Description
本發明係關於一種具備在機體的側部裝載苗的預備苗框、以及苗或肥料的輔助搬送構件的苗移植機。 The present invention relates to a seedling transplanting machine comprising a preliminary seedling frame for loading seedlings on the side of the body and an auxiliary conveying member for seedlings or fertilizer.
已知有如下苗移植機,在機體後部具備將苗栽種在農地中的苗栽種部,並且具備向農地供給肥料的施肥裝置,在該苗移植機中,在機體的側部具備由複數個預備載苗構件構成的預備苗框。 There is a seedling transplanting machine in which a seedling planting part that grows seedlings in agricultural land is provided at the rear of the body, and a fertilizing device that supplies fertilizer to the agricultural land is provided, and in the seedling transplanting machine, a plurality of preparations are provided on the side of the body. A seedling frame made up of seedling members.
在下述專利文獻1或2中,揭示有如下苗移植機,該苗移植機構成為,在由一根長的主連桿臂和兩根短的前側及後側副連桿臂構成的連桿機構上安裝複數個預備載苗構件,當使該連桿機構轉動時,能夠將前述複數個預備載苗構件切換成如下形態:複數個預備載苗構件成為上下多層並在俯視時為重複的層疊形態、和複數個預備載苗構件在前後方向上成為大致一條直線狀而展開的展開形態。 In the following Patent Document 1 or 2, there is disclosed a seedling transplanting mechanism which is a link mechanism composed of a long main link arm and two short front side and rear side sub-link arms A plurality of preliminary seedling members are mounted thereon, and when the link mechanism is rotated, the plurality of preliminary seedling members can be switched to a form in which a plurality of preliminary seedling members are stacked in a plurality of layers and are repeated in a plan view. And a plurality of pre-loaded seedling members are expanded in a substantially straight line shape in the front-rear direction.
因此,在專利文獻1或2記載的結構中,能夠切換複數個預備載苗構件的形態,提高從農地外裝載苗的裝載作業或向苗栽種部補充苗的補充作業的效率,並且能夠實現移動時的苗的裝載姿勢的穩定化。 Therefore, in the configuration described in Patent Document 1 or 2, it is possible to switch the form of a plurality of preliminary seedling-loading members, and to improve the efficiency of the loading operation of loading seedlings from the agricultural land or the replenishing operation of the seedlings, and to realize the movement. Stabilization of the loading posture of the seedlings.
尤其是,當在農地端存在水路時、或農地端的土質較差而 作業者不易靠近時,藉由使預備苗框朝前方突出,作業者不需要過度地伸出身體或手臂來進行苗的補充,因此大幅度地減少作業者的勞力,並且裝載苗所需要的時間變短,提高作業效率。 In particular, when there is a waterway at the farmland or the soil at the farmland is poor, When the operator is not easily approached, the operator does not need to excessively extend the body or the arm to replenish the seedlings by protruding the front frame, thereby greatly reducing the labor of the operator and the time required to load the seedlings. Shorten and improve work efficiency.
專利文獻1:日本特開2009-232809號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2009-232809
專利文獻2:日本特開2009-240224號公報 Patent Document 2: Japanese Laid-Open Patent Publication No. 2009-240224
在專利文獻1及2的苗移植機中,由於用施肥裝置向栽種的苗供給肥料,因此不僅進行苗的補充作業,還需要進行肥料的補充作業。因此,在將預備的苗裝載在預備苗框上時,也要將預備的肥料裝載在機體上,在施肥裝置中貯存的肥料減少時,無需返回到農地端便能進行肥料的補充。 In the seedling transplanting machines of Patent Documents 1 and 2, since the fertilizer is supplied to the planted seedlings by the fertilizing device, not only the seedlings are replenished, but also the fertilizer is required to be replenished. Therefore, when the prepared seedlings are loaded on the preliminary seedling frame, the prepared fertilizer is also loaded on the body, and when the fertilizer stored in the fertilizer application device is reduced, the fertilizer can be replenished without returning to the agricultural land.
然而,在專利文獻1及2的苗移植機中未設置與苗不同要從農地外裝載肥料並搬送到機體的肥料搬送用的構件,作業者需要將比苗重的肥料從農地端搬運到機體,存在作業者的勞力相對地增加的問題。 However, in the seedling transplanting machines of the patent documents 1 and 2, the member for fertilizer transfer which is different from the seedling to load the fertilizer from the agricultural land and is carried to the body is not provided, and the operator needs to transport the fertilizer which is heavier than the seedling from the farmland to the body. There is a problem that the labor of the operator is relatively increased.
尤其是,在農地端存在水路時、或農地端的土質較差等而難以從農地端直接將肥料裝載在機體上的狀況下,作業者不得不搬起沈重的肥料進入農地內,在腳踏在泥土上的不穩定的狀態下移動到機體。 In particular, when there is a waterway at the agricultural land, or when the soil at the farmland is poor, and it is difficult to directly load the fertilizer on the body from the farmland, the operator has to carry heavy fertilizer into the farmland and step on the soil. Move to the body in an unstable state.
雖然也能夠將肥料裝載在預備苗框上,但由於是假設將苗裝載在預備苗框上的情況,因此若用於沈重的肥料的裝載作業,則對預備苗框的構成構件施加的負荷較大,相比通常情況, 存在耐久性的下降變快、容易破損的問題。 Although it is also possible to load the fertilizer on the preliminary seedling frame, since it is assumed that the seedling is loaded on the preliminary seedling frame, if it is used for the loading operation of the heavy fertilizer, the load applied to the constituent members of the preliminary seedling frame is higher. Large, compared to the usual situation, There is a problem that the durability is lowered and the damage is easily broken.
如果減少裝載的肥料的量,雖然不會發生上述問題,但相對的肥料的裝載作業所需的時間變長,因此存在作業效率大幅度降低的問題。 If the amount of the loaded fertilizer is reduced, the above problem does not occur, but the time required for the loading operation of the relative fertilizer becomes long, and thus there is a problem that the work efficiency is largely lowered.
本發明的目的在於提供一種苗移植機,與預備苗框分開地設置肥料的搬送構件,能夠與農地端的狀態無關地裝載苗或肥料,有效地進行苗或肥料的裝載作業。 An object of the present invention is to provide a seedling transplanting machine in which a fertilizer conveying member is provided separately from a preliminary seedling frame, and it is possible to load seedlings or fertilizers independently of the state of the agricultural land, and to efficiently carry out the loading operation of the seedlings or the fertilizer.

在前述限制支柱24的上端部固定有切換裝置21,構成為藉由利用切換裝置21使連結三個預備載苗台20u、20m、20d的連桿臂41轉動,能夠將預備苗框19切換為層疊形態和展開形態。 The switching device 21 is fixed to the upper end portion of the restriction stay 24, and the link arm 41 that connects the three preparatory seedling stages 20u, 20m, and 20d is rotated by the switching device 21, whereby the preliminary seed frame 19 can be switched to Stacked form and expanded form.
該切換裝置21固定在前述限制支柱24、25的上端部,因此能抑制限制支柱24、25的上下長度並確保預備苗框19的連桿機構的轉動軌跡,因此可防止前述預備載苗台20u、20m、20d的位置過高且苗的裝載或取出變得困難之情況,而提高作業效率。 Since the switching device 21 is fixed to the upper end portions of the restriction stays 24 and 25, it is possible to suppress the vertical length of the support stays 24 and 25 and to ensure the rotation locus of the link mechanism of the preliminary seed frame 19, thereby preventing the aforementioned pre-loading stage 20u. The position of 20m, 20d is too high and the loading or unloading of the seedling becomes difficult, and the work efficiency is improved.
如圖5所示,為了防止作業者接觸構成前述切換裝置21的半圓形狀的齒輪32,做成切換裝置21由切換部罩31覆蓋的結構。 As shown in FIG. 5, in order to prevent an operator from coming into contact with the semicircular gear 32 constituting the switching device 21, the switching device 21 is covered by the switching portion cover 31.
圖5所示的該切換部罩31由於做成使前述齒輪32致動的切換致動器22的上部露出的結構,因此切換裝置21小型化地構成。此外,在切換部罩31形成切換致動器22的上部的覆蓋部,也可以做成覆蓋切換致動器22的結構。 The switching portion cover 31 shown in FIG. 5 has a structure in which an upper portion of the switching actuator 22 that activates the gear 32 is exposed. Therefore, the switching device 21 is configured in a small size. Further, the switching portion cover 31 forms a covering portion that switches the upper portion of the actuator 22, and may be configured to cover the switching actuator 22.
另外,將收納空的苗箱及空的取苗板等的空苗箱收放部33固定在前述限制支柱24、25上,並設置在行駛車體10的內側。 該空苗箱收放部33在本發明中係組合金屬製的棒體而構成的,但也可以使用其他材料來構成。此外,在圖1至圖4中,省略了空苗箱收放部33的圖示。 In addition, the empty seed box storage unit 33 that accommodates an empty seedling box and an empty seedling plate is fixed to the restriction stays 24 and 25, and is provided inside the traveling vehicle body 10. In the present invention, the empty box storage unit 33 is configured by combining metal rods, but may be formed using other materials. In addition, in FIGS. 1 to 4, the illustration of the empty box storage unit 33 is omitted.
藉由設置前述空苗箱收放部33,能夠收放使用後的空的苗箱及空的取苗板,因此能夠防止苗箱及取苗板被風吹起而落到農地中,節省作業者撿拾收集苗箱及取苗板的時間和勞力,提高作業效率。 By providing the empty seed box storage unit 33, it is possible to accommodate the empty seedling box and the empty seedling board after use, thereby preventing the seed box and the seedling board from being blown up by the wind and falling into the farmland, thereby saving the operator Pick up the time and labor of collecting seedling boxes and taking seedlings to improve work efficiency.
另外,藉由在預備苗框19與引擎罩13之間設置前述空苗箱收放部33,作業者在車體上幾乎不用移動便能夠將苗箱及取 苗板收放在空苗箱收放部33中,因此可減輕作業者的勞力。 Further, by providing the empty box storage portion 33 between the preliminary seed frame 19 and the hood 13, the operator can move the seedling box and take almost no movement on the vehicle body. The seedling plate is placed in the empty seed box storage portion 33, so that the labor of the operator can be reduced.
若將前述空苗箱收放部33配置在行駛車體10的外側,則存在如下問題,亦即,由於空苗箱收放部33的突出而無法使車體靠近牆壁,並且從駕駛者至空苗箱收放部33的距離變遠而難以到達空的苗箱及空的取苗板等。因此,如本實施形態1所示,配置靠車體內側是合理的,藉此提高苗移植機的操作性及作業性。 When the empty box storage unit 33 is disposed outside the traveling vehicle body 10, there is a problem in that the vehicle body cannot be brought close to the wall due to the protrusion of the empty box storage portion 33, and the driver is The distance between the empty box storage unit 33 becomes far, and it is difficult to reach an empty seedling box and an empty seedling board. Therefore, as shown in the first embodiment, it is reasonable to arrange the inner side of the vehicle body, thereby improving the operability and workability of the seedling transplanter.
接著,對預備苗框19和切換裝置21的連接結構、以及預備苗框19的動作進行說明。 Next, the connection structure of the preliminary seedling frame 19 and the switching device 21 and the operation of the preliminary seedling frame 19 will be described.

如圖6所示,在預備苗框19的層疊形態下,本實施形態1的切換裝置21為容納在從側面觀察時為預備載苗台20u、20m、20d的前後寬度的範圍內的前後寬度。藉由使切換裝置21的前後寬度比預備載苗台20u、20m、20d的前後寬度小,從而在層疊形態下切換裝置21不會從預備載苗台20u、20m、20d的前後寬度突出,能夠做成小型化的結構。 As shown in Fig. 6, in the stacked form of the preliminary seedling frame 19, the switching device 21 of the first embodiment accommodates the front and rear widths in the range of the front and rear widths of the preliminary load carrying tables 20u, 20m, and 20d when viewed from the side. . By making the front-back width of the switching device 21 smaller than the front-rear width of the preliminary load-bearing stages 20u, 20m, and 20d, the switching device 21 does not protrude from the front-back width of the preliminary load-bearing stages 20u, 20m, and 20d in the stacked form. Made into a compact structure.
此外,切換裝置21的前後寬度也可以與預備載苗台20u、20m、20d的前後寬度大致相同。 Further, the front-rear width of the switching device 21 may be substantially the same as the front-rear width of the preliminary load-bearing stages 20u, 20m, and 20d.
如圖6及圖7所示,三個預備載苗台20u、20m、20d在連桿臂41隔有間隔地連結。另外,該預備載苗台20u和預備載苗台20m由前側的第一副連桿臂42連結,預備載苗台20m和預 備載苗台20d由後側的第二副連桿臂43連結。 As shown in FIGS. 6 and 7, the three preparatory seedling stages 20u, 20m, and 20d are connected to each other at a distance between the link arms 41. Further, the preliminary seedling loading table 20u and the preliminary seedling loading table 20m are connected by the first sub-link arm 42 on the front side, and the pre-loading table 20m and the pre-loading table are prepared. The seedling stage 20d is connected by the second sub-link arm 43 on the rear side.
前述預備載苗台20u透過轉動部46轉動自如地與第一副連桿臂42連接,並透過轉動部47轉動自如地與連桿臂41連接。 The preliminary loading stage 20u is rotatably coupled to the first sub-link arm 42 via the rotating portion 46, and is rotatably coupled to the link arm 41 via the rotating portion 47.
前述預備載苗台20m透過轉動部48轉動自如地與第一副連桿臂42連接,並透過從動轉動軸45轉動自如地與連桿臂41連接,並透過轉動部49轉動自如地與第二副連桿臂43連接。 The preliminary loading stage 20m is rotatably coupled to the first sub-link arm 42 via the rotating portion 48, and is rotatably coupled to the link arm 41 via the driven rotating shaft 45, and is rotatably and movably transmitted through the rotating portion 49. The two sub-link arms 43 are connected.
前述預備載苗台20d透過轉動部50轉動自如地與連桿臂41連接,並透過轉動部51轉動自如地與第二副連桿臂43連接。 在前述連桿臂41的中央部且比前述從動轉動軸45更靠前側位置,設有將連桿臂41轉動自如地安裝在限制支柱24、25上的主轉動軸44。 The preliminary loading stage 20d is rotatably connected to the link arm 41 via the rotating portion 50, and is rotatably coupled to the second sub-link arm 43 via the rotating portion 51. A main rotating shaft 44 that rotatably attaches the link arm 41 to the regulating stays 24, 25 is provided at a position on the front side of the link arm 41 and above the driven rotating shaft 45.
此外,該主轉動軸44相當於本發明的軸的一個例子,主轉動軸44與連桿臂41連接的部分相當於本發明的連桿機構的轉動中心的部分的一個例子。 Further, the main rotation shaft 44 corresponds to an example of the shaft of the present invention, and an portion of the main rotation shaft 44 connected to the link arm 41 corresponds to an example of a portion of the rotation center of the link mechanism of the present invention.
另外,前述第二副連桿臂43在靠近預備載苗台20m的部分透過轉動軸52與限制支柱25的上端部連接,第二副連桿臂43構成為以該轉動軸52為中心能夠轉動。 Further, the second sub-link arm 43 is connected to the upper end portion of the regulating stay 25 through the rotating shaft 52 at a portion close to the preliminary loading table 20m, and the second sub-link arm 43 is configured to be rotatable about the rotating shaft 52. .
前述主轉動軸44做成藉由切換裝置21的切換致動器22的驅動來進行轉動的結構,伴隨主轉動軸44的轉動,連桿臂41轉動,伴隨連桿臂41的轉動,與其兩端連接的預備載苗台20u及預備載苗台20d分別被第一副連桿臂42及第二副連桿臂43限制,並且維持大致水平的狀態地移動。 The main rotating shaft 44 is configured to be rotated by the driving of the switching actuator 22 of the switching device 21, and with the rotation of the main rotating shaft 44, the link arm 41 rotates, with the rotation of the link arm 41, The pre-loading stage 20u and the pre-loading stage 20d which are connected to each other are restricted by the first sub-link arm 42 and the second sub-link arm 43, and are moved in a substantially horizontal state.
另外,伴隨連桿臂41的轉動,由從動轉動軸45連接的預備載苗台20m也被第一副連桿臂42及第二副連桿臂43限制,並且維持大致水平的狀態地移動。 Further, with the rotation of the link arm 41, the preliminary load carrying table 20m connected by the driven rotating shaft 45 is also restricted by the first sub-link arm 42 and the second sub-link arm 43, and is moved substantially in a horizontal state. .
在圖6所示的預備苗框19的層疊形態下,若連桿臂41朝 左轉動,則預備載苗台20u上升後,一邊下降一邊朝前方移動,預備載苗台20d下降後,一邊上升一邊朝後方移動。並且,預備苗框19成為圖8所示的展開形態。 In the stacked form of the preliminary seedling frame 19 shown in Fig. 6, if the link arm 41 faces When it is turned to the left, the pre-loading stage 20u is raised, and the front side is moved forward while descending, and the preliminary loading stage 20d is lowered, and then moved upward while moving. Further, the preliminary seedling frame 19 has an expanded form as shown in FIG.
圖15係顯示展開形態中預備苗框19的俯視圖。在此,省略了預備苗框19及切換裝置21以外的部分的圖示。前述連桿臂41、第一副連桿臂42及第二副連桿臂43相對於預備載苗台20u、20m、20d平行地配置在等距離的位置上,如圖15所示,在展開形態下,這些連桿臂41、42、43成為重疊的狀態。 Fig. 15 is a plan view showing the preliminary seedling frame 19 in the unfolded configuration. Here, illustration of portions other than the preliminary seed frame 19 and the switching device 21 is omitted. The link arm 41, the first sub-link arm 42, and the second sub-link arm 43 are disposed at equidistant positions in parallel with the preliminary load-bearing stages 20u, 20m, and 20d, as shown in FIG. In the form, the link arms 41, 42, and 43 are in an overlapping state.
另外,如圖5及圖15所示,從行駛車體10側朝向車體外側,依次配置切換裝置21、連桿臂41、第一副連桿臂42、第二副連桿臂43、預備載苗台20u、20m、20d,因此沒有妨礙裝載在預備載苗台20u、20m、20d上的苗的動作的構件,而容易進行苗墊塊的裝載。 Further, as shown in FIGS. 5 and 15, the switching device 21, the link arm 41, the first sub-link arm 42, and the second sub-link arm 43 are arranged in order from the side of the traveling vehicle body 10 toward the outside of the vehicle body. Since the seedling stages 20u, 20m, and 20d are provided, there is no member that hinders the movement of the seedlings placed on the preliminary seedling loading stages 20u, 20m, and 20d, and the seedling mat is easily loaded.
在現有的乘用型插秧機中,設置決定收放狀態的預備載苗構件的停止位置的止動器,因此在每次將預備載苗構件切換為展開形態或層疊形態時都需要手動作業來解除該止動器的作用狀態,存在作業效率下降的問題,並且還必需做成將該止動器切換為作用狀態和非作用狀態的結構,存在預備載苗構件的結構變得複雜的問題。 In the conventional passenger-type rice transplanter, since the stopper for determining the stop position of the preliminary seed-loading member in the retracted state is provided, manual work is required every time the preliminary seed-carrying member is switched to the expanded form or the stacked form. When the action state of the stopper is released, there is a problem that the work efficiency is lowered, and it is necessary to change the stopper to the active state and the non-acting state, and the configuration of the preliminary load-carrying member is complicated.
並且,設置支承構件,該支承構件用於在將預備載苗構件切換為展開形態時,防止所裝載的苗從預備載苗構件的前側及後側落下,但由於該支承構件的上部為朝上方突出的形狀,在將苗裝載在預備載苗構件上時,作業者必需避開該支承構件的上部地裝載苗,因此不容易裝載苗,存在苗的補充作業的效率下降的問題。 Further, a support member for preventing the loaded seedling from falling from the front side and the rear side of the preliminary seed carrying member when the preliminary seed carrying member is switched to the expanded form is provided, but since the upper portion of the supporting member is upward In the protruding shape, when the seedling is placed on the preliminary seedling member, the operator must carry the seedlings away from the upper portion of the supporting member, so that it is not easy to load the seedling, and there is a problem that the efficiency of the seedling replenishing operation is lowered.
再者,由於未在預備載苗構件彼此之間設置輔助苗移動的 搬送輔助旋轉體等,因此存在苗朝後方移動所需要的勞力增加且作業效率下降的問題。 Furthermore, since the auxiliary seedling members are not provided with auxiliary seedling movement between them Since the auxiliary rotating body or the like is conveyed, there is a problem that the labor required for moving the seedling rearward increases and the work efficiency is lowered.
如圖10、圖12及圖15所示,在三個預備載苗台20u、20m、20d的前側兩端部分別形成朝前方突出的一對前側突出部38a1、38b1、38c1,在後側端部中央分別形成朝後方突出的後側突出部38a2、38b2、38c2。 As shown in Fig. 10, Fig. 12, and Fig. 15, a pair of front side protruding portions 38a1, 38b1, and 38c1 projecting forward are formed at the front end portions of the three preliminary load carrying tables 20u, 20m, and 20d, respectively, at the rear end. Rear center projections 38a2, 38b2, and 38c2 projecting rearward are formed in the center of each of the portions.
因此,在使三個預備載苗台20u、20m、20d處於展開形態時,位於機體前側的預備載苗台20u、20m的後部突出部38a2、38b2配置在從側面觀察時與位於機體後側的預備載苗台20m、20d的前側突出部38b1、38c1重複的位置。 Therefore, when the three preparatory seedling stages 20u, 20m, and 20d are in the unfolded configuration, the rear protruding portions 38a2 and 38b2 of the preliminary loading stage 20u and 20m located on the front side of the machine body are disposed on the rear side of the body when viewed from the side. The positions at which the front side projections 38b1, 38c1 of the seedling stage 20m, 20d are repeated are prepared.
此外,上述前側突出部38a1、38b1、38c1係前側止動器部的一個例子,上述後側突出部38a2、38b2、38c2係後側止動器部的一個例子。藉此,在三個預備載苗台20u、20m、20d處於沿前後方向排列的展開形態時,由於能夠使三個預備載苗台20u、20m、20d沿前後方向排列,因此能夠使裝載在預備載苗台20u、20m、20d上的苗箱平滑地朝後側移動,相比以往能夠提高作業效率。 Further, the front side protruding portions 38a1, 38b1, and 38c1 are examples of the front side stopper portion, and the rear side protruding portions 38a2, 38b2, and 38c2 are examples of the rear side stopper portion. In this way, when the three preparatory seedling stages 20u, 20m, and 20d are in the developed form arranged in the front-rear direction, the three preparatory seedling stages 20u, 20m, and 20d can be arranged in the front-rear direction, so that the loading can be performed in preparation. The seedling boxes on the seedling platforms 20u, 20m, and 20d smoothly move toward the rear side, which improves work efficiency compared to the past.
並且,無需進行將前側止動器部38a1、38b1、38c1及後側止動器部38a2、38b2、38c2切換為作用狀態或非作用狀態的操作,便能夠將預備載苗台20u、20m、20d切換為展開形態或層疊形態,因此能夠防止預備載苗台20u、20m、20d的結構變得複雜,並且提高作業效率。 Further, it is not necessary to perform an operation of switching the front side stopper portions 38a1, 38b1, 38c1 and the rear side stopper portions 38a2, 38b2, 38c2 to the active state or the inactive state, so that the preliminary seed carrying stations 20u, 20m, 20d can be mounted. Since the configuration is switched to the expanded form or the stacked form, it is possible to prevent the structure of the preliminary load carrying stages 20u, 20m, and 20d from being complicated, and to improve work efficiency.
如圖10、圖12的側視圖所示,在三個預備載苗台20u、20m、20d的前側突出部38a1、38b1、38c1形成前低後高傾斜形狀(前低後高傾斜部)的引導面,使該引導面比各預備載苗台20u、20m、20d的載苗面高。 As shown in the side views of Fig. 10 and Fig. 12, the front side protruding portions 38a1, 38b1, and 38c1 of the three preliminary load carrying tables 20u, 20m, and 20d form a front low rear high inclined shape (front low rear high inclined portion). The guide surface is made higher than the seed carrying surface of each of the preliminary seedling stages 20u, 20m, and 20d.
並且,在展開形態下,在從側面觀察時,在前述引導面或比引導面更靠後方配置後側止動器部。另外,使三個預備載苗台20u、20m、20d的後側突出部38a2、38b2、38c2比各預備載苗台20u、20m、20d的載苗面高,並且與前側突出部38a1、38b1、38c1的上表面相同,或比前述上表面低。 Further, in the unfolded form, the rear side stopper portion is disposed rearward of the guide surface or the guide surface when viewed from the side. Further, the rear side protruding portions 38a2, 38b2, and 38c2 of the three preliminary seed carrying tables 20u, 20m, and 20d are made higher than the seed carrying surfaces of the respective prepumps 20u, 20m, and 20d, and the front side protruding portions 38a1, 38b1. The upper surface of 38c1 is the same or lower than the aforementioned upper surface.
如上所述,將前側突出部38a1、38b1、38c1設為前低後高的傾斜部,藉此在將三個預備載苗台20u、20m、20d切換為展開狀態,並使苗箱等從前側的預備載苗台20u、20m朝後側的預備載苗台20m、20d移動時,該苗箱能夠往上載置於前低後高的傾斜部並朝後方移動,因此苗箱的移動變得容易,與以往相比能夠提高作業效率。 As described above, the front side protruding portions 38a1, 38b1, and 38c1 are set to be inclined portions having a front lower rear height, whereby the three preliminary load carrying tables 20u, 20m, and 20d are switched to the unfolded state, and the seedling box or the like is moved from the front side. When the pre-loading table 20u and 20m are moved toward the rear loading stage 20m and 20d, the seedling box can be placed on the inclined portion which is placed at the front lower rear height and moved rearward, so that the movement of the seedling box becomes easy. It can improve work efficiency compared with the past.
另外,藉由將形成於前側突出部38a1、38b1、38c1的引導面的後部的前側止動器部、和形成於後側突出部38a2、38b2、38c2的後側止動器部形成為比各預備載苗台20u、20m、20d的載苗面高,從而將三個預備載苗台20u、20m、20d切換到層疊形態時,能夠利用前側突出部38a1、38b1、38c1和後側突出部38a2、38b2、38c2防止裝載在各預備載苗台20u、20m、20d上的苗箱等的前後移動,因此可防止苗箱從各預備載苗台20u、20m、20d朝下方落下,無需拾起落下的苗箱,與以往相比能夠提高作業效率。 Further, the front side stopper portion formed at the rear portion of the guide surface of the front side protruding portions 38a1, 38b1, 38c1 and the rear side stopper portion formed at the rear side protruding portions 38a2, 38b2, 38c2 are formed as each When the seedling surface of the preparatory seedling stages 20u, 20m, and 20d is high, when the three preliminary seedling stages 20u, 20m, and 20d are switched to the stacked form, the front side protruding portions 38a1, 38b1, 38c1 and the rear side protruding portion 38a2 can be utilized. 38b2, 38c2 prevent the movement of the seedling boxes and the like placed on the respective pre-loading stages 20u, 20m, and 20d, so that the seedling boxes can be prevented from falling downward from the respective pre-loading stages 20u, 20m, and 20d, and there is no need to pick up and drop. The seedling box can improve work efficiency compared with the past.
在前述各預備載苗台20u、20m、20d的一對前側突出部38a1、38b1、38c1的左右之間、且該預備載苗台20u、20m、20d的底部分別設有用於支承前側的預備載苗台20u、20m的後側突出部38a2、38b2等的支承構件38a3、38b3、38c3,該支承構件38a3、38b3、38c3在一對前側突出部38a1、38b1、38c1彼此之間的空間部突出而形成。 The front side of each of the pair of front side protrusions 38a1, 38b, and 38c1 of each of the preliminary load carrying stages 20u, 20m, and 20d is provided with a front load for supporting the front side of each of the bottoms of the preliminary load carrying stages 20u, 20m, and 20d. Support members 38a3, 38b3, 38c3 of the rear side projections 38a2, 38b2 of the seedlings 20u and 20m, the support members 38a3, 38b3, 38c3 projecting in the space between the pair of front side projections 38a1, 38b1, 38c1 form.
此外,在前側突出部38a1、38b1、38c1及後側突出部38a2、38b2中的一方設置支承構件38a3、38b3、38c3,做成利用該支承構件38a3、38b3、38c3支承前側突出部38a1、38b1、38c1及後側突出部38a2、38b2中的另一方的結構。 Further, one of the front side protruding portions 38a1, 38b1, 38c1 and the rear side protruding portions 38a2, 38b2 is provided with supporting members 38a3, 38b3, 38c3, and the front side protruding portions 38a1, 38b1 are supported by the supporting members 38a3, 38b3, 38c3.

藉由做成上述結構,由於能夠在各預備載苗台20m、20d的前側突出部38b1、38c1的左右之間利用支承構件38b3、38c3支承各自的前側的預備載苗台20u、20m的後側突出部38a2、38b2,因此各預備載苗台20u、20m、20d不會過於下降,展開狀態的各預備載苗台20u、20m、20d可確實地以大致相同的高度成為排列姿勢,苗箱的裝載作業變得容易,與以往相比能夠提高作業效率。 With the above-described configuration, the rear side of each of the preparatory seedling stages 20u and 20m on the front side can be supported by the support members 38b3 and 38c3 between the right and left of the front side protruding portions 38b1 and 38c1 of the respective pre-loading stages 20m and 20d. Since the protruding portions 38a2, 38b2 are not excessively lowered, the preliminary loading stage 20u, 20m, and 20d in the unfolded state can be reliably arranged at substantially the same height, and the seedling box is The loading work is easy, and the work efficiency can be improved compared with the past.
另外,藉由在各預備載苗台20u、20m、20d的底部設置支承構件38a3、38b3、38c3,從而後側突出部38a2、38b2、38c2的上端部位於與前側突出部38a1、38b1、38c1的上端部大致相同的高度或下側,因此往上載置至具有前低後高的傾斜部的前側突出部38a1、38b1、38c1的苗箱的移動平滑地進行,與以往相比能夠提高作業效率。 Further, by providing the support members 38a3, 38b3, and 38c3 at the bottoms of the respective prepumps 20u, 20m, and 20d, the upper end portions of the rear side projections 38a2, 38b2, and 38c2 are located at the front projections 38a1, 38b1, and 38c1. Since the upper end portions have substantially the same height or the lower side, the movement of the seedling boxes placed on the front side protruding portions 38a1, 38b1, and 38c1 having the inclined portions having the front lower rear height is smoothly performed, and the work efficiency can be improved as compared with the related art.
另外,在三個預備載苗台20u、20m、20d的左右側面的前後的四個部位,分別配置防止苗箱落下的第一、第二、第三分隔壁38a4、38b4、38c4。 Further, the first, second, and third partition walls 38a4, 38b4, and 38c4 for preventing the seedling box from falling are disposed at four positions on the front and rear sides of the left and right side surfaces of the three preliminary loading stage 20u, 20m, and 20d, respectively.
並且,也可以做成將第二移動連桿構件39b的轉動支點44設置在與預備載苗台20m的從動轉動軸45相同的軸上,從而第二預備載苗台20m不會朝前後移動的結構。 Further, the rotation fulcrum 44 of the second moving link member 39b may be disposed on the same axis as the driven rotating shaft 45 of the preliminary loading table 20m, so that the second preliminary loading table 20m does not move forward and backward. Structure.
圖14(a)、圖14(b)係顯示在處於展開形態的各預備載苗台20u、20m、20d上移動的苗的側視圖,圖14(c)係省略苗的俯視圖。另外,圖14(c)、圖14(d)係設有輔助苗的搬 送的輔助搬送旋轉體的俯視圖、主要部分的側視圖。 Figs. 14(a) and 14(b) are side views showing the seedlings that move on the respective seedling loading stages 20u, 20m, and 20d in the developed state, and Fig. 14(c) is a plan view in which the seedlings are omitted. In addition, FIG. 14(c) and FIG. 14(d) are provided with auxiliary seedlings. The top view of the auxiliary conveyance rotating body and the side view of the main part.
在前述三個預備載苗台20u、20m、20d的前側突出部38a1、38b1、38c1中的預備載苗台20m及預備載苗台20d的前側突出部38b1、38c1上分別配置用以空轉以輔助搬送苗的搬送輔助旋轉體47b、47c。此時,做成搬送輔助旋轉體47b、47c的上表面比前述前側突出部38b1、38c1的前低後高的傾斜面的上部更朝上方突出的結構。 The preliminary loading stage 20m of the front side protruding portions 38a1, 38b1, and 38c1 of the three preliminary loading stage 20u, 20m, and 20d and the front side protruding portions 38b1 and 38c1 of the preliminary loading stage 20d are respectively arranged to be idling to assist The transfer auxiliary rotation bodies 47b and 47c of the seedlings are conveyed. At this time, the upper surfaces of the conveyance auxiliary rotating bodies 47b and 47c are protruded upward from the upper portions of the inclined surfaces higher than the front side protrusions 38b1 and 38c1.
藉由在前述前側突出部38b1、38c1設置搬送輔助旋轉體47b、47c,在處於展開形態,作業者朝預備載苗台20m及預備載苗台20d壓入苗後移動苗時,能夠減輕對苗的移動施加的力,因此減輕作業者的勞力。 By providing the conveyance auxiliary rotating bodies 47b and 47c in the front side protruding portions 38b1 and 38c1, when the operator moves the seedlings to the preliminary seedling loading table 20m and the preliminary seedling loading table 20d in the expanded state, the seedlings can be reduced. The force exerted by the movement, thus reducing the labor of the operator.
並且,搬送輔助旋轉體47b、47c的上表面位於比前側突出部38b1、38c1更靠上方,藉此輔助搬送旋轉體47b、47c可確實地發揮作用。 Further, the upper surfaces of the conveyance assist rotating bodies 47b and 47c are located above the front side protrusions 38b and 38c1, whereby the auxiliary conveyance rotating bodies 47b and 47c can function reliably.
圖16係顯示切換裝置21的結構的說明圖。如該圖16所示,前述限制支柱24、25配置在車體內側,前述連桿臂41配置在比限制支柱24、25更靠外側。另外,在限制支柱24、25的上端部固定有固定支撐板58,在固定支撐板58上固定有切換致動器22。 FIG. 16 is an explanatory diagram showing the configuration of the switching device 21. As shown in FIG. 16, the restriction stays 24 and 25 are disposed inside the vehicle body, and the link arms 41 are disposed outside the restriction stays 24 and 25. Further, a fixed support plate 58 is fixed to the upper end portions of the restriction stays 24, 25, and a switching actuator 22 is fixed to the fixed support plate 58.
前述主轉動軸44固定在連桿臂41上,而且貫通形成有齒部55的圓弧的中心位置並固定在齒輪32上。並且,主轉動軸44轉動自如地與限制支柱24、25連接,做成主轉動軸44、齒輪32及連桿臂41為一體轉動的結構。 The main rotation shaft 44 is fixed to the link arm 41, and penetrates the center position of the circular arc in which the tooth portion 55 is formed and is fixed to the gear 32. Further, the main rotating shaft 44 is rotatably coupled to the regulating stays 24, 25, and the main rotating shaft 44, the gear 32, and the link arm 41 are integrally rotated.
如圖16所示,從行駛車體10的內側朝向外側依序配置有前述前後一對限制支柱24、25、切換致動器22、齒輪32、連桿臂41,並且如圖15所示,在連桿臂41的外側連接預備苗框19。 As shown in FIG. 16, the front and rear pair of restriction stays 24, 25, the switching actuator 22, the gear 32, and the link arm 41 are sequentially disposed from the inner side toward the outer side of the traveling vehicle body 10, and as shown in FIG. A preliminary seedling frame 19 is connected to the outside of the link arm 41.
藉由做成前述結構,從在輔助底板27上進行作業的作業者觀察,成為切換裝置21位於比連桿臂41、第一副連桿臂42及第二副連桿臂43更靠前側的結構,因此能夠防止作業者的手或手臂碰觸到轉動中的連桿臂41、第一副連桿臂42及第二副連桿臂43,能夠提高作業的安全性。 With the above configuration, the operator who is working on the sub-chassis 27 observes that the switching device 21 is located further forward than the link arm 41, the first sub-link arm 42, and the second sub-link arm 43. With this configuration, it is possible to prevent the operator's hand or arm from touching the rotating link arm 41, the first sub-link arm 42, and the second sub-link arm 43, and it is possible to improve work safety.
構成前述切換裝置21的切換致動器22、軸著於該切換致動器22的輸出軸(省略圖示)的轉動齒輪61及齒輪32如圖5所示,做為與限制支柱24、25的上部一起被前述切換部罩31覆蓋的結構。 The switching actuator 22 constituting the switching device 21 and the rotating gear 61 and the gear 32 that are axially mounted on the output shaft (not shown) of the switching actuator 22 are shown as a restriction post 24 and 25 as shown in FIG. The upper portion is covered by the switching portion cover 31 as described above.
此外,前述切換部罩31也可以做成例如為下方敞開的箱型形狀,並從切換裝置21的上部覆蓋的結構。另外,也可以做成為側面敞開的箱型形狀,並從前述限制支柱24、25側的側面覆蓋來覆蓋切換裝置21,然後在敞開的側面部分安裝蓋的結構。 Further, the switching portion cover 31 may be configured to have a box shape that is open at the lower side and that is covered from the upper portion of the switching device 21. Further, it is also possible to form a box shape which is open on the side, and covers the switching device 21 from the side surface on the side of the restriction stay 24, 25, and then attaches the cover to the open side portion.
若將切換部罩31做成下方敞開的箱型形狀並從切換裝置21的上方裝卸自如地安裝的結構,則切換部罩31的拆卸變得容易,因此能夠提高維修保養性。 When the switching portion cover 31 has a box shape that is open at the lower side and is detachably attached from above the switching device 21, the detachment of the switching portion cover 31 is facilitated, so that the maintenance performance can be improved.
此外,將切換致動器22配置在接近齒輪32的位置,則能夠使切換裝置21的尺寸更加小型化。 Further, by arranging the switching actuator 22 at a position close to the gear 32, the size of the switching device 21 can be further reduced in size.
另外,也可以將限制支柱24、25做成如下結構,亦即,使各自內部為空心的管形狀,使向切換致動器22供給電源的電線束通過限制支柱24的內部而與切換致動器22連接。 Further, the regulating stays 24 and 25 may be configured such that the respective inner portions have a hollow tube shape, and the electric wire bundle that supplies power to the switching actuator 22 passes through the inside of the restriction stay 24 and is switched and actuated. The device 22 is connected.
藉由做成該結構,即使做成使限制支柱24、25轉動時使預備苗框19朝向車體的內側的結構,也能夠防止向切換致動器22供給電源的電線束纏繞在一起。 With this configuration, it is possible to prevent the electric wire bundle that supplies power to the switching actuator 22 from being entangled even when the preparation frame 19 is oriented toward the inside of the vehicle body when the restriction stays 24 and 25 are rotated.
圖10係顯示設有停止板73a1、73a2的層疊形態的預備苗框19的側視圖,圖11係顯示停止板73a1、73a2的安裝位置的 主要部分側視圖。並且,圖12係顯示設有停止板73a1、73a2的展開形態的預備苗框19的側視圖,圖13係顯示停止板73a1、73a2的安裝位置的主要部分側視圖。 Fig. 10 is a side view showing the preliminary seedling frame 19 in a stacked form in which the stop plates 73a1, 73a2 are provided, and Fig. 11 shows the mounting position of the stop plates 73a1, 73a2. Side view of the main part. 12 is a side view showing the preliminary seedling frame 19 in which the stop plates 73a1 and 73a2 are deployed, and FIG. 13 is a side view showing a main portion of the mounting positions of the stop plates 73a1 and 73a2.
設置停止板73a1、73a2,該停止板73a1、73a2用於在操作前述切換操作開關而將預備苗框19切換為層疊形態及展開形態時,與連桿臂41、第一及第二副連桿臂42、43接觸而限制其以上的轉動。該停止板73a1、73a2以層疊形態分別設置在中央的預備載苗台20m和下層的預備載苗台20d的側面。 Stop plates 73a1, 73a2 for switching the preparatory frame 19 to the stacked form and the expanded form when operating the switching operation switch, and the link arm 41, the first and second secondary links The arms 42, 43 are in contact to limit the rotation thereof. The stop plates 73a1 and 73a2 are respectively provided in a stacked form on the side surface of the preliminary seed load table 20m at the center and the preliminary load table 20d of the lower layer.
如圖10及圖11所示,若預備苗框19為層疊形態,則連桿臂41與位於下側的停止板73a2接觸而限制其以上的轉動,藉由持續該轉動限制,在切換致動器22上產生一定以上的負荷、或者成為過熱狀態的控制裝置100使切換致動器22停止。 As shown in FIG. 10 and FIG. 11, when the preliminary seedling frame 19 is in a stacked form, the link arm 41 comes into contact with the lower stop plate 73a2 to restrict the rotation thereof, and the switching is activated by continuing the rotation restriction. The control device 100 that generates a certain amount of load on the device 22 or that is in an overheated state stops the switching actuator 22.
另外,如圖12及圖13所示,若預備苗框19成為展開形態,則連桿臂41與位於前側的停止板73a1接觸而限制其以上的轉動,藉由持續該轉動限制,在切換致動器22上產生一定以上的負荷、或者成為過熱狀態的控制裝置100使切換致動器22停止。 Further, as shown in FIG. 12 and FIG. 13, when the preliminary seedling frame 19 is in the unfolded configuration, the link arm 41 comes into contact with the stop plate 73a1 on the front side to restrict the rotation thereof, and the switching is continued by the rotation restriction. The control device 100 that generates a certain amount of load or a superheated state on the actuator 22 stops the switching actuator 22.
如上所述,切換致動器22的停止係透過控制裝置100來進行,但也可以做成如下結構,亦即,使該切換致動器22為電動馬達,在該電動馬達的內部配置使用通電切換構件92的通電路徑,當根據負荷而達到一定溫度以上時,該通電切換構件92彎曲而從通電狀態強制性地被切換到非通電狀態。 As described above, the stop of the switching actuator 22 is transmitted through the control device 100, but the switching actuator 22 may be an electric motor, and the electric power may be placed inside the electric motor. When the energization path of the switching member 92 reaches a certain temperature or higher according to the load, the energization switching member 92 is bent and forcibly switched from the energization state to the non-energized state.
若採用上述結構,則在將預備苗框19切換為層疊形態或展開形態時,作業者不需要操作切換操作開關73來使切換致動器22停止,因此能夠集中於其他操作,相比以往能夠提高作業效率。 According to the above configuration, when the preliminary seed frame 19 is switched to the stacked form or the expanded form, the operator does not need to operate the switching operation switch 73 to stop the switching actuator 22, so that it is possible to concentrate on other operations, and it is possible to concentrate on other operations. Improve work efficiency.
另外,由於做成在預備苗框19成為層疊形態或展開形態 時,連桿臂41與停止板73a1、73a2接觸的結構,因此可防止因機體的振動而使連桿臂41、第一及第二副連桿臂42、43動作而使得預備苗框19朝前後搖動,可防止苗落下,並且可減輕搖動引起的預備苗框19及其他構成構件的磨損。 In addition, it is formed in a stacked form or a expanded form in the preliminary seedling frame 19. When the link arm 41 is in contact with the stop plates 73a1, 73a2, it is possible to prevent the link arm 41 and the first and second sub-link arms 42 and 43 from being operated by the vibration of the body, so that the preparation frame 19 is directed toward The front and rear shaking can prevent the seedling from falling, and can reduce the wear of the preliminary seedling frame 19 and other constituent members caused by the shaking.
再者,在將預備苗框19切換為層疊形態或展開形態時,由於能夠省略使切換致動器22停止的開關等的構成構件及電路,因此大幅度地削減構件件數的同時,結構變得簡單。 In addition, when the preliminary seedling frame 19 is switched to the stacked form or the expanded form, the constituent members and the circuit such as the switch that stops the switching actuator 22 can be omitted. Therefore, the number of components is greatly reduced and the structure is changed. It's simple.
以圖17(a)及圖17(b)對本發明的切換裝置21的結構進行說明。 The configuration of the switching device 21 of the present invention will be described with reference to Figs. 17(a) and 17(b).
設置構成前述切換裝置21的蓋板78,在比使連桿臂41動作的齒輪32更靠車體的外側的位置安裝輔助板79。並且,在該蓋板78與輔助板79的左右之間安裝保持板80,將該保持板80設為朝輔助板79側延伸而由該輔助板79支撐,做成利用該輔助板79和保持板80從左右支撐切換致動器22的結構。 The cover plate 78 constituting the switching device 21 is provided, and the auxiliary plate 79 is attached to a position outside the vehicle body than the gear 32 that operates the link arm 41. Further, a holding plate 80 is attached between the cover plate 78 and the left and right of the auxiliary plate 79, and the holding plate 80 is extended toward the auxiliary plate 79 side and supported by the auxiliary plate 79, and the auxiliary plate 79 is used and held. The plate 80 supports the structure of the actuator 22 from the left and right.
在上述結構的切換裝置21中,在蓋板78與輔助板79的左右之間設置保持板80,利用該保持板80和輔助板79從左右支撐切換致動器22,由此在連桿臂41、第一及第二副連桿臂42、43與停止板73a1、73a2接觸而施加負荷時,即使向保持板80施加欲使切換致動器22移動的力,也能夠由蓋板78和保持板80來承受該力,因此能夠以足夠的強度確實地支撐切換致動器22。 In the switching device 21 of the above configuration, a holding plate 80 is provided between the left and right sides of the cover plate 78 and the auxiliary plate 79, and the switching actuator 22 is supported from the left and right by the holding plate 80 and the auxiliary plate 79, thereby being at the link arm 41. When the first and second sub-link arms 42 and 43 are in contact with the stop plates 73a1 and 73a2 to apply a load, even if a force for moving the switching actuator 22 is applied to the holding plate 80, the cover plate 78 and The retaining plate 80 is subjected to this force, so that the switching actuator 22 can be reliably supported with sufficient strength.
另外,藉由防止切換致動器22的移動,能夠防止切換致動器22與齒輪32的距離分離,因此不需要切換裝置21的調整作業,能夠提高作業效率。 Further, by preventing the movement of the switching actuator 22, it is possible to prevent the distance between the switching actuator 22 and the gear 32 from being separated. Therefore, the adjustment work of the switching device 21 is not required, and the work efficiency can be improved.
如圖18及圖19所示,在基礎支撐框架23的上部朝向機體內側設置安裝構件101,在該安裝構件101的機體內側端部設置 預備苗框19的限制支柱24、25。 As shown in FIGS. 18 and 19, a mounting member 101 is provided toward the inside of the body in the upper portion of the base support frame 23, and is disposed at the inner end of the body of the mounting member 101. The support pillars 24, 25 of the seedling frame 19 are prepared.
另外,在該安裝構件101的機體外側設置支撐構件102,在該支撐構件102中、在以層疊形態沿上下方向重疊的預備載苗台20u、20m、20d的左右方向的中央部的成為下方的位置設置第一轉動構件103。並且,在該第一轉動構件103的上部設置轉動構件104的基部側,在該轉動構件104的端部側設置輔助裝載構件105。 In addition, the support member 102 is provided on the outer side of the body of the attachment member 101, and the center portion of the preparation stage 102 in the left-right direction of the preliminary load-bearing stages 20u, 20m, and 20d which are stacked in the vertical direction in a stacked form is below. The first rotating member 103 is disposed at a position. Further, a base portion side of the rotating member 104 is provided at an upper portion of the first rotating member 103, and an auxiliary loading member 105 is provided at an end portion side of the rotating member 104.
如圖18所示,若使轉動構件104朝機體前方轉動,則輔助裝載構件105位於在展開形態下位於最前列的預備載苗台20u的下方,並成為朝向機體前側突出的姿勢,並且使轉動構件104朝機體後方轉動,則輔助裝載構件105位於在展開形態下位於最後列的預備載苗台20d的下方,並成為朝向機體前側突出的姿勢。此時,做為輔助裝載構件105的機體外側端部位於預備載苗台20u、20m、20d的機體外側端部的下方,剩餘部分不會露出機體外側的結構。 As shown in Fig. 18, when the turning member 104 is rotated toward the front of the body, the auxiliary loading member 105 is positioned below the preliminary loading table 20u which is located at the forefront in the deployed state, and is in a posture that protrudes toward the front side of the body, and is rotated. When the member 104 is rotated toward the rear of the body, the auxiliary loading member 105 is positioned below the preliminary loading table 20d in the last row in the unfolded state, and is in a posture protruding toward the front side of the body. At this time, the outer end portion of the body as the auxiliary loading member 105 is located below the outer end portion of the body of the preparatory loading platforms 20u, 20m, and 20d, and the remaining portion does not expose the outer structure of the body.
此外,雖然該輔助裝載構件105比預備苗框19的機體外側端部更朝外側突出之情況並不佳,但比機體內側端部更朝內側移動,且移動到底板11中、作業者無法移動的(腳無法靠近的)部位也沒有問題。 Further, although the auxiliary loading member 105 is less protruded outward than the outer end portion of the body of the preliminary seedling frame 19, it is moved more inward than the inner end portion of the body, and moves into the bottom plate 11, and the operator cannot move. There is no problem with the part (the foot cannot be close).
在上述底板11上移動時,作業者必須確保立足地的穩定性,基本上不會讓腳靠近底板11的端部。因此,即使輔助裝載構件105位於底板11的端部的上方,也不會與作業者的腳接觸,亦不會因作業者踩踏而使輔助裝載構件105破損。 When moving on the above-mentioned bottom plate 11, the operator must ensure the stability of the ground, and basically does not allow the foot to approach the end of the bottom plate 11. Therefore, even if the auxiliary loading member 105 is positioned above the end portion of the bottom plate 11, it does not come into contact with the operator's foot, and the auxiliary loading member 105 is not damaged by the operator's stepping on.
藉由使輔助裝載構件105的機體內側端部位於比前述預備苗框19的機體內側端部更靠內側,作業者容易目視輔助裝載構件105,而且靠近在底板11上進行作業的作業者,因此作業者 容易從輔助裝載構件105取出肥料袋,而提高作業效率。 By positioning the inner end portion of the auxiliary loading member 105 on the inner side of the inner side end portion of the preliminary seedling frame 19, the operator can easily visually recognize the auxiliary loading member 105 and approach the operator who performs work on the bottom plate 11, and therefore Operators It is easy to take out the fertilizer bag from the auxiliary loading member 105, and the work efficiency is improved.
如圖22(a)、圖22(b)、圖23(a)、圖23(b)所示,在前述第一轉動構件103的下部形成一字形或十字形的第一鎖定槽103a,在前述安裝構件101上設置上下轉動自如的轉動限制構件103b,做成將該轉動限制構件103b插入到第一鎖定槽103a來限制轉動構件104的轉動的結構。在將該第一鎖定槽103a做成一字形時,在使輔助裝載構件105朝機體前方或後方移動時,轉動限制構件103b能夠插入到第一鎖定槽103a中,在做成十字形時,即使在使輔助裝載構件105朝機體外側方向轉動(使轉動構件104轉動90度)的狀態下,轉動限制構件103b亦能夠插入到第一鎖定槽103a中。 As shown in Fig. 22 (a), Fig. 22 (b), Fig. 23 (a), and Fig. 23 (b), a first locking groove 103a having a shape of a cross or a cross is formed at a lower portion of the first rotating member 103, The mounting member 101 is provided with a rotation restricting member 103b that is rotatable up and down, and the rotation restricting member 103b is inserted into the first lock groove 103a to restrict the rotation of the rotating member 104. When the first locking groove 103a is formed in a shape of a line, when the auxiliary loading member 105 is moved toward the front or the rear of the body, the rotation restricting member 103b can be inserted into the first locking groove 103a, even when the cross shape is formed, The rotation restricting member 103b can also be inserted into the first locking groove 103a in a state where the auxiliary loading member 105 is rotated in the outer side of the body (rotating the rotating member 104 by 90 degrees).
此外,在比前述轉動構件104更靠機體內側,在上下方向上設有前述限制支柱24、25,藉此該限制支柱24、25成為轉動臂104朝機體內側方向轉動的限制構件。 Further, the restricting stays 24 and 25 are provided in the vertical direction on the inner side of the body than the rotating member 104, whereby the restricting stays 24 and 25 serve as restricting members for rotating the rotating arm 104 toward the inside of the machine body.
藉此,可防止使轉動構件104過度移動,輔助裝載構件105過度朝機體內側方向移動,不需要使輔助裝載構件105移動到適當的位置的作業,提高作業效率的同時,可防止輔助裝載構件105與引擎罩13等接觸而使得輔助裝載構件105、引擎罩13、以及周邊的構成構件破損。 Thereby, it is possible to prevent the rotation member 104 from being excessively moved, and the auxiliary loading member 105 is excessively moved toward the inside of the machine body, and it is not necessary to move the auxiliary loading member 105 to an appropriate position, and the work efficiency can be improved, and the auxiliary loading member 105 can be prevented. The auxiliary loading member 105, the hood 13, and the surrounding constituent members are broken by contact with the hood 13 or the like.
藉由做成前述結構,在從農地端裝載肥料袋時,當使轉動構件104轉動到機體前側,能夠使輔助裝載構件105朝機體的前方突出,因此在農地外的作業者能夠容易地將肥料裝載到機體上,而提高作業效率。 According to the above configuration, when the fertilizer bag is loaded from the agricultural land, when the rotating member 104 is rotated to the front side of the body, the auxiliary loading member 105 can be protruded toward the front of the body, so that the operator outside the farm can easily apply the fertilizer. Loaded on the body to improve work efficiency.
尤其是,在農地端具有水路的農地、或在農地端的立足地不穩定的農地中進行作業時,作業者不需要過度地伸出身體將肥料袋裝載在機體上,因此可減輕作業者的勞力,並且由於不 需要拾起掉落的肥料袋的作業,因此提高作業效率。 In particular, when working on a farmland with a waterway at the end of the farmland or in an unstable farmland at the end of the farmland, the operator does not need to overextend the body to load the fertilizer bag on the body, thereby reducing the labor of the operator. And because not It is necessary to pick up the fallen fertilizer bag, thus improving work efficiency.
另外,由於能夠使轉動構件104朝機體外側轉動,輔助裝載構件105以朝機體外側突出的姿勢保持,因此即使機體橫靠在農地端,也能夠使輔助裝載構件105靠近農地端,因此能夠對應各式各樣的作業條件,而冀望提高作業效率、減輕作業者的勞力。 Further, since the rotation member 104 can be rotated toward the outside of the body, the auxiliary loading member 105 can be held in a posture that protrudes toward the outside of the body. Therefore, even if the body is laterally opposed to the farmland, the auxiliary loading member 105 can be brought closer to the farmland end, so that it is possible to correspond to each other. Various types of working conditions, and hope to improve work efficiency and reduce the labor of the operators.
並且,藉由做成使輔助裝載構件105移動時、使轉動構件104朝機體外側方向轉動的結構,轉動構件104或輔助裝載構件105不在底板11上移動,因此作業者無需避開轉動構件104或輔助裝載構件105,能夠在底板11上進行苗或肥料的補充作業,而提高作業效率。 Further, when the auxiliary loading member 105 is moved and the rotating member 104 is rotated toward the outside of the machine body, the rotating member 104 or the auxiliary loading member 105 does not move on the bottom plate 11, so that the operator does not need to avoid the rotating member 104 or The auxiliary loading member 105 can perform a supplementary operation of seedlings or fertilizer on the bottom plate 11, thereby improving work efficiency.
再者,藉由做成不論使輔助裝載構件105朝機體前部、後部哪方移動,輔助裝載構件105的外側端部都位於預備苗框19的外側端部的大致正下方的結構,從而能夠防止輔助裝載構件105朝機外突出,因此防止輔助裝載構件105與牆壁等接觸而破損,而提高耐久性。 Further, by making the auxiliary loading member 105 move toward the front and the rear of the body, the outer end portion of the auxiliary loading member 105 is located substantially directly below the outer end portion of the preliminary seedling frame 19, thereby making it possible to Since the auxiliary loading member 105 is prevented from protruding toward the outside of the machine, the auxiliary loading member 105 is prevented from coming into contact with the wall or the like and broken, and durability is improved.
另外,由於若使輔助裝載構件105朝機體後部側移動,則能夠使輔助裝載構件105接近施肥裝置17,因此作業者從輔助裝載構件105取下肥料袋並移動到施肥裝置17的距離變短,而提高作業效率並且減輕作業者的勞力。 Further, when the auxiliary loading member 105 is moved toward the rear side of the body, the auxiliary loading member 105 can be brought close to the fertilizer application device 17, so that the distance that the operator removes the fertilizer bag from the auxiliary loading member 105 and moves to the fertilizer application device 17 becomes short. Improve work efficiency and reduce the labor of the operator.
並且,能夠在進行肥料的補充作業之前將肥料袋裝載到輔助裝載構件105上,因此減少了裝載到底板11上的肥料袋的數量,作業者在進行苗或肥料的補充作業時容易移動,而提高作業效率。 Further, the fertilizer bag can be loaded onto the auxiliary loading member 105 before the fertilizer filling operation, so that the number of the fertilizer bags loaded on the bottom plate 11 is reduced, and the operator can easily move while performing the seedling or fertilizer replenishing operation. Improve work efficiency.
如上所述,若使前述輔助裝載構件105朝機體前側移動,則容易從農地外裝載肥料。然而,若準備肥料的位置從使輔助 裝載構件105朝前方移動後的位置位於機體內側、或機體外側,則作業者搬起肥料袋進行移動的距離稍微變長,無法充分提高作業效率、或減輕勞力。 As described above, when the auxiliary loading member 105 is moved toward the front side of the body, it is easy to load the fertilizer from the outside of the farm. However, if the position of the fertilizer is prepared from the auxiliary When the position where the loading member 105 moves forward is located inside the machine body or outside the machine body, the distance that the operator moves the fertilizer bag and moves is slightly longer, and the work efficiency cannot be sufficiently improved or the labor can be reduced.
另外,在將輔助裝載構件105分別設置在左右的預備苗框19、19的下方的結構中,即使能夠幾乎不移動地將肥料裝載在左右一方的輔助裝載構件105上,若不搬起肥料袋移動便無法裝載在左右另一方的輔助裝載構件105上,無法充分冀望提高作業效率、減輕勞力。 Further, in the configuration in which the auxiliary loading members 105 are respectively disposed below the left and right preliminary seedling frames 19 and 19, the fertilizer can be loaded on the left and right auxiliary loading members 105 without moving, and the fertilizer bag is not lifted. The movement cannot be carried on the other auxiliary loading member 105 on the left and the right, and it is not possible to sufficiently improve the work efficiency and labor.
在上述的圖18及圖19的結構中,如果使轉動構件104朝機體內側轉動直到與限制支柱24、25接觸,則能夠使輔助裝載構件105靠近機體內側。然而,此時,從進行作業的作業者觀察,輔助裝載構件105在農地端處於傾斜方向上,因此作業者在將肥料袋裝載到輔助裝載構件105上時,需要適當地使肥料袋朝向傾斜方向裝載,不僅不能提高作業效率,有時反而在裝載上花費時間和勞力,存在作業效率下降的問題。 In the above-described configuration of Figs. 18 and 19, when the rotating member 104 is rotated toward the inside of the body until it comes into contact with the regulating stays 24, 25, the auxiliary loading member 105 can be brought closer to the inside of the body. However, at this time, when the worker who performs the work observes that the auxiliary loading member 105 is in the oblique direction at the agricultural land end, the operator needs to appropriately tilt the fertilizer bag toward the oblique direction when loading the fertilizer bag onto the auxiliary loading member 105. Loading not only does not improve work efficiency, but sometimes it takes time and labor to load, and there is a problem that work efficiency is lowered.
作為解決上述問題的方法,具有圖19及圖20所示的結構。 As a method for solving the above problem, the configuration shown in Figs. 19 and 20 is obtained.
在設置於前述安裝構件101上的支撐構件102的基部側,設置第三轉動構件106而將該支撐構件102構成為前後自由轉動,在該第三轉動構件106的上部形成一字形或十字形的第二鎖定槽106a,並在前述限制支柱24、25上以上下轉動自如的方式設置轉動止動器106b,做成將該轉動止動器106b插入到第二鎖定槽106a中來限制前述支撐構件102的轉動的結構。 On the base side of the support member 102 provided on the aforementioned mounting member 101, a third rotating member 106 is provided to configure the supporting member 102 to be freely rotatable forward and backward, and a top or cross shape is formed on the upper portion of the third rotating member 106. The second locking groove 106a is provided with the rotation stopper 106b rotatably above and below the restriction stays 24, 25, and the rotation stopper 106b is inserted into the second locking groove 106a to restrict the support member. The rotating structure of 102.
此外,在做成上述結構時,將前述轉動限制構件103b插入到第一鎖定槽103a中來限制前述轉動構件104的轉動,而使轉動臂構件處於不進行無法預期的動作的狀態。 Further, in the above configuration, the rotation restricting member 103b is inserted into the first lock groove 103a to restrict the rotation of the rotating member 104, and the rotating arm member is in a state in which an unexpected operation is not performed.
在上述的結構中,做成如下結構,亦即,成為支撐構件102 的轉動支點的第三轉動構件106位於比成為前述轉動構件104的第一轉動構件103更靠機體內側,若使支撐構件102朝機體前側轉動到輔助裝載構件105的前端部與農地端大致平行的位置,則輔助裝載構件105位於機體的前側、在圖20中位於底板11的前側,因此即使在農地端中放置肥料袋的位置靠近機體內側,作業者也能夠搬起肥料袋不移動地進行肥料的裝載作業。因此,提高作業效率並且減輕作業者的勞力。 In the above configuration, the following structure is formed, that is, the support member 102 is formed. The third rotating member 106 of the pivot point is located closer to the inside of the body than the first rotating member 103 that becomes the rotating member 104. When the supporting member 102 is rotated toward the front side of the body, the front end portion of the auxiliary loading member 105 is substantially parallel to the agricultural end. In the position, the auxiliary loading member 105 is located on the front side of the body, and is located on the front side of the bottom plate 11 in FIG. 20, so that even if the position where the fertilizer bag is placed in the agricultural land end is close to the inside of the body, the operator can lift the fertilizer bag and move the fertilizer without moving. Loading job. Therefore, the work efficiency is improved and the labor of the operator is reduced.
此外,若做成使輔助裝載構件105移動到底板11的前側時,支撐構件102與限制支柱24、25的接觸的配置結構,則無需進行支撐構件102的細微的操作便能夠移動到裝載位置,因此提高作業效率。 Further, when the auxiliary loading member 105 is moved to the front side of the bottom plate 11, the arrangement structure in which the supporting member 102 is in contact with the regulating stays 24, 25 can be moved to the loading position without performing minute operations of the supporting member 102. Therefore, the work efficiency is improved.
藉由做成上述配置結構,若使支撐構件102朝機體後方轉動,則支撐構件102的轉動在與限制支柱24、25接觸的位置受到限制,但此時,輔助裝載構件105的機體外側端部位於預備苗框19的機體外側端部的下方,因此可防止輔助裝載構件105與牆壁等接觸而破損,並且由於輔助裝載構件105不位於底板11的上方,因此作業者在底板11上容易進行苗或肥料的補充作業,而提高作業效率。 With the arrangement described above, when the support member 102 is rotated toward the rear of the body, the rotation of the support member 102 is restricted at a position in contact with the restriction stays 24, 25. However, at this time, the outer end portion of the auxiliary loading member 105 is provided. It is located below the outer end of the body of the preliminary seedling frame 19, so that the auxiliary loading member 105 can be prevented from being damaged by contact with the wall or the like, and since the auxiliary loading member 105 is not located above the bottom plate 11, the operator can easily carry out the seedling on the bottom plate 11. Or supplementation of fertilizers to improve work efficiency.
另外,在設置左右的輔助裝載構件105、105的結構中,由於能夠使左右的輔助裝載構件105、105分別朝機體內側移動,因此作業者在左右的輔助裝載構件105、105之任一構件上都容易裝載肥料袋,而進一步提高作業效率。 Further, in the configuration in which the auxiliary loading members 105 and 105 are provided, the left and right auxiliary loading members 105 and 105 can be moved toward the inside of the body, so that the operator is on any of the left and right auxiliary loading members 105 and 105. It is easy to load fertilizer bags, which further improves work efficiency.
在上述的結構中,若將第二鎖定槽106a形成為十字形,則輔助裝載構件105還能夠成為朝機體的左右外側方向突出的姿勢,但由於支撐構件102的第三轉動構件106設置在靠機體內側,因此與使轉動構件104轉動的結構相比較,輔助裝載構件 105朝機體外側的突出量變小。藉此,在機體側方具有足夠的空間時,使轉動構件104轉動而使輔助裝載構件105的突出量較多對於作業者來說容易進行肥料裝載。 In the above configuration, when the second lock groove 106a is formed in a cross shape, the auxiliary loading member 105 can also be in a posture protruding toward the left and right outer sides of the body, but the third rotating member 106 of the support member 102 is disposed on the support member 102. The inside of the body, thus the auxiliary loading member compared to the structure that rotates the rotating member 104 The amount of protrusion of 105 toward the outside of the body becomes small. Thereby, when there is a sufficient space on the side of the machine body, the rotation of the rotating member 104 and the large amount of protrusion of the auxiliary loading member 105 make it easy for the operator to load the fertilizer.
然而,在住宅地等、農地端的附近存在牆壁的場所等,若輔助裝載構件105的突出量過多則與牆壁接觸,因此存在無法利用轉動構件104的轉動進行輔助裝載構件105朝機體側方的突出操作的情況。此時,藉由使支撐構件102轉動,在抑制突出量的狀態下使輔助裝載構件105朝機體側方突出,從而能夠防止輔助裝載構件105與牆壁的接觸,並且減輕肥料的裝載作業所需要的作業者的勞力。 However, in a place such as a residential site or the like where there is a wall in the vicinity of the farmland end, if the amount of protrusion of the auxiliary loading member 105 is too large, the wall is in contact with the wall. Therefore, the auxiliary loading member 105 cannot be protruded toward the side of the body by the rotation of the rotating member 104. The case of operation. At this time, by rotating the support member 102, the auxiliary loading member 105 is protruded toward the side of the body while suppressing the amount of protrusion, thereby preventing the auxiliary loading member 105 from coming into contact with the wall and reducing the load required for the loading operation of the fertilizer. The labor of the operator.
上述的結構係輔助裝載構件105靠近機體內側的結構,但也可以如圖21所示,能夠做成將輔助裝載構件105固定在機體外側位置的結構。 The above-described configuration is a configuration in which the auxiliary loading member 105 is close to the inside of the machine body. However, as shown in FIG. 21, the auxiliary loading member 105 may be fixed to a position outside the machine body.
將前述第一轉動構件103和轉動構件104構成為從前述支撐構件102自由裝卸,並且在該支撐構件102的外側端部設置延長構件108的基部側。並且,藉由在該延長構件108的端部安裝輔助裝載構件105,能夠做成使輔助裝載構件105位於從機體大幅度朝外側離開的位置的結構。 The first rotating member 103 and the rotating member 104 are configured to be detachably attached from the support member 102, and the base side of the extending member 108 is provided at the outer end portion of the supporting member 102. Further, by attaching the auxiliary loading member 105 to the end portion of the extension member 108, the auxiliary loading member 105 can be positioned to be largely separated from the body.
在該結構中,使安裝有延長構件108的支撐構件102轉動,使輔助裝載構件105朝機體前側或機體後側移動都不會與限制支柱24、25接觸,因此需要作業者在肥料袋的裝載作業位置、以及輔助裝載構件105的搬送停止位置對轉動止動器106b進行操作來成為限制安裝有延長構件108的支撐構件102的轉動的狀態。 In this configuration, the support member 102 to which the extension member 108 is attached is rotated, and the auxiliary loading member 105 is moved toward the front side of the body or the rear side of the body without coming into contact with the restriction stays 24, 25, so that the operator needs to load the fertilizer bag. The work position and the conveyance stop position of the auxiliary loading member 105 operate the rotation stopper 106b to restrict the rotation of the support member 102 to which the extension member 108 is attached.
另外,移動到機體後側的輔助裝載構件105的機體外側端部位於預備苗框19的機體外側端部的下方時,需要限制安裝有 延長構件108的支撐構件102的轉動。此時,第二鎖定槽106a形成為一字形或十字形,藉此能夠將轉動止動器106b可插入第二鎖定槽106a的位置判斷為安裝有延長構件108的支撐構件102的轉動停止位置。 Further, when the outer end portion of the auxiliary loading member 105 that is moved to the rear side of the body is located below the outer end portion of the body of the preliminary seedling frame 19, it is necessary to restrict the installation. The rotation of the support member 102 of the elongate member 108. At this time, the second locking groove 106a is formed in a straight shape or a cross shape, whereby the position at which the rotation stopper 106b can be inserted into the second locking groove 106a can be determined as the rotation stop position of the support member 102 to which the extension member 108 is attached.
在上述的結構中,相比圖18、圖19的結構,轉動支點位於機體外側,若使轉動構件104朝機體前側轉動到輔助裝載構件105的前端部與農地端大致平行的位置,則成為輔助裝載構件105從機體較大地離開的結構,因此在進行肥料的裝載作業時在周圍沒有障礙物,能夠效率良好地進行肥料的裝載作業。 In the above configuration, the pivot point is located outside the body than the structure of Figs. 18 and 19, and the rotation member 104 is rotated toward the front side of the body to a position where the front end portion of the auxiliary loading member 105 is substantially parallel to the farmland end. Since the loading member 105 has a structure in which the body is largely separated from the body, there is no obstacle around the fertilizer loading operation, and the fertilizer can be efficiently loaded.
另外,藉由在延長構件108的端部設置輔助裝載構件105,從而在使輔助裝載構件105朝機體後側移動時,能夠使輔助裝載構件105與施肥裝置17的間隔變窄,因此作業者將肥料袋移動到施肥裝置17上的距離變短,而提高作業效率、減輕作業者的勞力。 Further, by providing the auxiliary loading member 105 at the end of the extension member 108, when the auxiliary loading member 105 is moved toward the rear side of the body, the interval between the auxiliary loading member 105 and the fertilizer application device 17 can be narrowed, so the operator will The distance that the fertilizer bag moves to the fertilizer application device 17 becomes shorter, and the work efficiency is improved and the labor of the operator is reduced.
此外,在圖18、圖19的結構中,也能夠使輔助裝載構件105朝離開機體外側的位置移動,但由於轉動支點位於預備苗框19的下方,因此輔助裝載構件105朝前側的突出量少,而且在從進行作業的作業者觀察時,輔助裝載構件105在農地端中處於傾斜方向上,因此作業者在將肥料袋裝載到輔助裝載構件105上時,需要適當地使肥料袋朝向傾斜方向裝載,不僅不能提高作業效率,有時反而在裝載上花費時間和勞力,存在作業效率下降的問題。 Further, in the configuration of Figs. 18 and 19, the auxiliary loading member 105 can be moved to a position away from the outside of the body, but since the pivot point is located below the preliminary frame 19, the amount of protrusion of the auxiliary loading member 105 toward the front side is small. Moreover, when viewed from an operator who performs the work, the auxiliary loading member 105 is in the oblique direction in the agricultural land end, so when the operator loads the fertilizer bag onto the auxiliary loading member 105, it is necessary to appropriately tilt the fertilizer bag toward the oblique direction. Loading not only does not improve work efficiency, but sometimes it takes time and labor to load, and there is a problem that work efficiency is lowered.
如圖24(a)、圖24(b)所示,係將前述輔助裝載構件105切換到肥料的裝載作業或向施肥裝置17進行補充的作業位置、進行苗的栽種作業時或作業結束時的收納位置的結構。前述輔助裝載構件105透過安裝有第二轉動構件109的安裝構件110 安裝在前述支撐構件102、轉動構件104或延長構件108的任一構件上。此時,做成如下結構,亦即,使該第二轉動構件109作為轉動支點來使輔助裝載構件105轉動,能夠移動到俯視時與前述預備苗框19重疊的位置。 As shown in Fig. 24 (a) and Fig. 24 (b), the auxiliary loading member 105 is switched to the loading operation of the fertilizer or the work position to be replenished to the fertilizer application device 17, the planting operation for the seedling, or the end of the work. The structure of the storage position. The auxiliary loading member 105 passes through the mounting member 110 to which the second rotating member 109 is mounted Mounted on any of the aforementioned support members 102, rotating members 104 or elongated members 108. At this time, the second rotating member 109 is rotated as a pivot point to rotate the auxiliary loading member 105, and can be moved to a position overlapping the preliminary seedling frame 19 in plan view.
並且,做成如下結構,亦即,以連結彈簧112連結該第二轉動構件109的下部側、和設在支撐構件102、轉動構件104或延長構件108上的連結銷111的下部側,藉此在對輔助裝載構件105進行轉動操作時,越過支點前,利用該連結彈簧112的張力維持作業位置或收納位置。 Further, the lower side of the second rotating member 109 and the lower side of the connecting pin 111 provided on the supporting member 102, the rotating member 104 or the extension member 108 are connected by the connecting spring 112, whereby When the auxiliary loading member 105 is rotated, the working position or the storage position is maintained by the tension of the connecting spring 112 before the fulcrum is passed.
此外,前述連結彈簧112具有在未受到強大的力時不會越過支點的程度的彈壓力。藉此,在苗的栽種作業時或機體的收納時,能夠使輔助裝載構件105以第二轉動構件109為轉動支點移動到與預備苗框19重疊的位置,因此可防止輔助裝載構件105堵塞作業者乘降的機體的前方或側方,在作業者從機體乘降時不需要使輔助裝載構件105移動,而提高作業效率。 Further, the aforementioned coupling spring 112 has an elastic pressure that does not exceed the fulcrum when a strong force is not applied. Thereby, the auxiliary loading member 105 can be moved to the position overlapping the preliminary seedling frame 19 with the second rotating member 109 as the pivot point during the planting operation of the seedling or the storage of the body, so that the auxiliary loading member 105 can be prevented from being clogged. In front of or behind the body of the descending body, it is not necessary to move the auxiliary loading member 105 when the operator rides and descends from the body, thereby improving work efficiency.
另外,由於能夠防止在機體收納時輔助裝載構件105成為朝機體前方或機體側方突出的姿勢,因此能夠使機體的前後寬度、或左右寬度變得小型化,故不需要取得收納所需要的大的空間,而提高收納性。 In addition, since the auxiliary loading member 105 can be prevented from being protruded toward the front of the body or the side of the body when the body is stored, the front and rear widths or the left and right widths of the body can be reduced in size, so that it is not necessary to obtain a large size required for storage. Space, while improving storage.
並且,在裝載並移動肥料時,亦即,從機體前側朝後側轉動操作輔助裝載構件105時,能夠防止手碰觸到輔助裝載構件105、或轉動時受到的離心力而導致輔助裝載構件105在作業者意想不到的時刻進行轉動,因此可防止肥料袋落下,且不需要撿拾肥料袋的作業。 Further, when the fertilizer is loaded and moved, that is, when the auxiliary loading member 105 is rotated from the front side to the rear side of the body, it is possible to prevent the hand from hitting the auxiliary loading member 105 or the centrifugal force received during the rotation, thereby causing the auxiliary loading member 105 to The operator rotates at an unexpected time, so that the fertilizer bag can be prevented from falling, and the operation of picking up the fertilizer bag is not required.
另外,在成為前述轉動構件104的轉動支點的第一轉動構件103、或成為前述支撐構件102的轉動支點的第三轉動構件 106的附近,安裝對前述支撐構件102或轉動構件104進行轉動操作的、俯視時為L字形狀的轉動操作桿113。 Further, the first rotating member 103 that becomes the pivot point of the rotating member 104, or the third rotating member that becomes the pivot point of the supporting member 102 In the vicinity of 106, a rotary operation lever 113 having an L shape in plan view is attached to the support member 102 or the rotary member 104.
藉由做成上述結構,能夠將肥料袋裝載在輔助裝載構件105上,並使支撐構件102、轉動構件104或延長構件108朝向機體後側轉動的轉動方向、和使輔助裝載構件105從預備苗框19的下方朝機體後側轉動的轉動方向為相同方向,因此在利用轉動操作桿113對支撐構件102、轉動構件104進行轉動操作時,藉由裝載在輔助裝載構件105上的肥料袋的重量或離心力,可防止輔助裝載構件105轉動,將從農地外裝載的肥料袋立刻用於施肥裝置17的肥料補充作業時,不需要額外的轉動操作桿113的操作,故提高作業效率。 With the above configuration, the fertilizer bag can be loaded on the auxiliary loading member 105, and the rotation direction of the support member 102, the rotating member 104 or the extension member 108 toward the rear side of the body, and the auxiliary loading member 105 can be prepared from the seedlings. The rotation direction of the lower side of the frame 19 toward the rear side of the body is the same direction, and therefore the weight of the fertilizer bag loaded on the auxiliary loading member 105 when the support member 102 and the rotating member 104 are rotated by the rotary operation lever 113 Alternatively, the centrifugal force can prevent the auxiliary loading member 105 from rotating, and when the fertilizer bag loaded from the agricultural land is immediately used for the fertilizer replenishing operation of the fertilizer application device 17, the operation of rotating the operation lever 113 is not required, so that the work efficiency is improved.
另外,藉由做成利用連結彈簧112的張力來將輔助裝載構件105維持在作業位置或收納位置,若越過支點則利用連結彈簧112的張力來切換作業位置和收納位置的結構,作業者不需要在越過支點後再施加轉動操作的力,可減輕作業者的勞力。 In addition, the auxiliary loading member 105 is maintained at the working position or the storage position by the tension of the connecting spring 112, and when the fulcrum is crossed, the structure of the working spring and the storage position are switched by the tension of the connecting spring 112, and the operator does not need to The force of the turning operation is applied after the fulcrum is passed, and the labor of the operator can be reduced.
並且,藉由在支撐構件102或轉動構件104的轉動支點的附近設置轉動操作桿113,作業者能夠以較輕的力進行越過支點的操作,因此進一步減輕作業者的勞力。 Further, by providing the turning operation lever 113 in the vicinity of the pivoting fulcrum of the support member 102 or the rotating member 104, the operator can perform the operation of crossing the fulcrum with a light force, thereby further reducing the labor of the operator.
上述的輔助裝載構件105做成如下結構,亦即,藉由使第一轉動限制構件103b或轉動止動器106b出入於第一鎖定槽103a或第二鎖定槽106a,來切換轉動狀態和非轉動狀態。然而,在該結構中,每當作業者使輔助裝載構件105移動時都需要鎖定的開關操作,存在作業者的勞力多少增加的問題。 The auxiliary loading member 105 is configured to switch between the rotation state and the non-rotation by causing the first rotation restricting member 103b or the rotation stopper 106b to enter and exit the first locking groove 103a or the second locking groove 106a. status. However, in this configuration, the switch operation requiring locking is required every time the operator moves the auxiliary loading member 105, and there is a problem that the labor of the operator is somewhat increased.
為了解決上述的問題,如圖25所示,在前述限制支柱24、25上安裝滑動支撐構件114,該滑動支撐構件114設置在支撐構件102的基部側,在該滑動支撐構件114的上部形成轉動限 制用的凹部114a。並且,在前述限制支柱24、25上固設進入該凹部114a的限制構件115,在該限制構件115及滑動支撐構件114的下方固設限制該滑動支撐構件114的下降的下降止動器116,並且在前述滑動支撐構件114與基礎支撐框架23的上下之間,以伸縮自如的方式設置朝上方對滑動支撐構件114施力的彈壓構件117。 In order to solve the above problem, as shown in FIG. 25, a slide supporting member 114 is provided on the aforementioned restricting stays 24, 25, which is provided on the base side of the support member 102, and a rotation is formed at the upper portion of the slide support member 114. limit A recess 114a for use. Further, a restriction member 115 that enters the recess portion 114a is fixed to the restriction stays 24, 25, and a lowering stopper 116 that restricts the lowering of the slide support member 114 is fixed under the restriction member 115 and the slide support member 114, Further, between the slide support member 114 and the upper and lower sides of the base support frame 23, the elastic member 117 that urges the slide support member 114 upward is provided in a telescopic manner.
此外,前述支撐構件102與圖19、圖21等所示的結構不同,做成即便裝載或不裝載肥料袋也位於安裝構件101上的結構,並做成以限制支柱24、25為轉動支點朝前後方向轉動的結構。支點位置係靠近第三轉動構件106的位置,因此成為在輔助裝載構件105移動到靠近機體內側的位置時,位於與農地端部大致平行的位置的結構。 Further, the support member 102 is different from the structure shown in Figs. 19, 21, etc., and is configured to be placed on the mounting member 101 even with or without a fertilizer bag, and is configured to restrict the stays 24, 25 as pivot points toward Structure that rotates in the front and rear direction. Since the fulcrum position is close to the position of the third rotating member 106, it is located at a position substantially parallel to the agricultural land end when the auxiliary loading member 105 is moved to a position close to the inside of the body.
根據上述的結構,若在輔助裝載構件105上裝載肥料袋,則根據肥料袋的重量使得輔助裝載構件105下降,並且連動滑動支撐構件114而一邊按壓彈壓構件117一邊沿限制支柱24、25下降。於是,形成於滑動支撐構件114上的凹部114a位於比限制構件115更下方,因此支撐構件102能夠以限制支柱24、25為轉動支點朝機體前後方向轉動,能夠使輔助裝載構件105移動。 According to the above configuration, when the fertilizer bag is loaded on the auxiliary loading member 105, the auxiliary loading member 105 is lowered in accordance with the weight of the fertilizer bag, and the sliding support member 114 is interlocked, and the pressing members 117 are pressed while descending along the regulating stays 24, 25. Then, since the concave portion 114a formed on the slide supporting member 114 is located below the restricting member 115, the support member 102 can be rotated in the front-rear direction of the body with the regulating stays 24, 25 as the pivot points, and the auxiliary loading member 105 can be moved.
因此,若在輔助裝載構件105上裝載肥料、或者作業者朝下方按下輔助裝載構件105,則轉動限制狀態被解除,由於為了在輔助裝載構件105上裝載肥料並朝施肥裝置17搬送、或進行肥料袋的裝載作業,可以朝機體前側移動,因此轉動機構成為簡單的結構,且成為容易組裝或拆解的維修保養性高的結構。 Therefore, when the auxiliary loading member 105 is loaded with the fertilizer or the operator pushes the auxiliary loading member 105 downward, the rotation restriction state is released, and the fertilizer is loaded onto the auxiliary loading member 105 and transported to the fertilizer application device 17 or performed. Since the loading operation of the fertilizer bag can be moved toward the front side of the body, the rotating mechanism has a simple structure and is highly maintainable and easy to assemble or disassemble.
另外,作業者進行的轉動限制解除操作僅為肥料袋的裝載、或輔助裝載構件105的按下操作,因此可防止作業者的勞 力增加。 Further, the rotation restriction releasing operation by the operator is only the loading of the fertilizer bag or the pressing operation of the auxiliary loading member 105, so that the operator can be prevented. The force increases.
如圖25(a)、圖25(b)所示,在前述滑動支撐構件114上,在圓周上彼此分離180度的位置分別形成一個凹部114a,共形成兩個。另一方面,若進入凹部114a內則限制支撐構件102的轉動並使輔助裝載構件105處於非轉動狀態的限制構件115在限制支柱24、25的圓周上彼此分離90度的位置上形成有一個、共形成有四個。另外,下降止動器116也可以做成在能夠抵住滑動支撐構件114的位置(例如,前述四個限制構件115、115、115、115的下方位置)設置一個或複數個突起體的結構,也可以做成能夠抵住滑動支撐構件114的圓形狀。 As shown in Fig. 25 (a) and Fig. 25 (b), on the slide supporting member 114, a recess portion 114a is formed at a position separated from each other by 180 degrees on the circumference, and two are formed in total. On the other hand, if the restriction member 115 which restricts the rotation of the support member 102 and causes the auxiliary loading member 105 to be in a non-rotation state to enter the concave portion 114a is formed at a position separated from each other by 90 degrees on the circumference of the restriction stays 24, 25, There are four in total. In addition, the lowering stopper 116 may be configured to be provided with one or a plurality of protrusions at a position capable of abutting against the sliding support member 114 (for example, a position below the four restriction members 115, 115, 115, and 115). It is also possible to form a circular shape that can withstand the sliding support member 114.
在圖26中,在機體的左右兩側分別設有劃線構件200,該劃線構件200與進行苗的栽種作業的作業位置相鄰,在下一工序的作業位置的農地面上形成直進行駛的基準線。該劃線構件200做成如下結構,亦即,為了進行苗的栽種而使苗栽種部16下降時,左右一側朝下方轉動而在農地面上形成基準線,並且,另一方的劃線構件200成為從農地面大幅度朝上方退避的姿勢。該劃線構件200的切換轉動操作藉由使苗栽種部16進行升降動作時、使設在劃線構件200的基部側的切換致動器201致動來進行。 In Fig. 26, a scribe member 200 is provided on each of the left and right sides of the body, and the scribe member 200 is adjacent to the work position at which the seedling is planted, and forms a straight forward travel on the agricultural ground at the work position of the next step. Baseline. The scribing member 200 has a configuration in which, when the seedling planting portion 16 is lowered for planting the seedlings, the left and right sides are rotated downward to form a reference line on the agricultural floor, and the other scribing member is formed. 200 is a posture that is largely retreated from the farm floor. The switching rotation operation of the scribing member 200 is performed by actuating the switching actuator 201 provided on the base side of the scribing member 200 when the seedling planting portion 16 is moved up and down.
此外,做成如下結構,亦即,若使前述苗栽種部16上升則切換致動器201致動,朝大幅度地離開農地面的上方對前述劃線構件200進行轉動操作,並且若使苗栽種部16下降則儲存在控制裝置100中的與前次的致動方向相反側的劃線構件200朝下方轉動並與農地面接觸。 Further, when the seedling planting portion 16 is raised, the switching actuator 201 is actuated, and the scribing member 200 is rotated upward to largely move away from the agricultural floor, and if the seedling is made When the planting portion 16 is lowered, the scribing member 200 stored on the side opposite to the previous actuation direction stored in the control device 100 is rotated downward and comes into contact with the agricultural ground.
為了利用該機構,也可以如圖27(a)、圖27(b)、圖29所示做成如下結構,亦即,若滑動支撐構件114下降到限制構 件115無法進入前述凹部114a內的位置,則設置檢測該滑動支撐構件114的接近的下降檢測構件118,若該下降檢測構件118檢測出滑動支撐構件114的接近,則前述切換致動器201致動,使劃線構件200朝下方轉動。 In order to utilize this mechanism, as shown in FIGS. 27(a), 27(b), and 29, the following structure may be employed, that is, if the sliding support member 114 is lowered to the restraining structure If the member 115 cannot enter the position in the recess 114a, a drop detecting member 118 that detects the approach of the sliding support member 114 is provided. If the drop detecting member 118 detects the approach of the sliding support member 114, the switching actuator 201 causes The scribe member 200 is rotated downward.
利用上述結構,在使輔助裝載構件105朝機體後側移動時,能夠防止輔助裝載構件105或所裝載的肥料袋與劃線構件200接觸,因此不必在輔助裝載構件105的轉動操作前另外進行使劃線構件200下降的操作,而冀望提高作業效率,並且防止劃線構件200、輔助裝載構件105的破損。 With the above configuration, when the auxiliary loading member 105 is moved toward the rear side of the body, the auxiliary loading member 105 or the loaded fertilizer bag can be prevented from coming into contact with the scribing member 200, so that it is not necessary to additionally perform the rotation operation of the auxiliary loading member 105 before the rotation operation of the auxiliary loading member 105. The operation of the scribing member 200 is lowered, and the work efficiency is improved, and the damage of the scribing member 200 and the auxiliary loading member 105 is prevented.
此外,也可以如圖27(a)、圖27(b)及圖29所示做成如下結構,亦即,在將轉動限制構件103b或轉動止動器106b朝轉動限制解除位置操作時的移動位置上設置前述下降檢測構件118,劃線構件200與轉動限制構件103b或轉動止動器106b的轉動限制的解除操作連動而下降。 Further, as shown in Figs. 27(a), 27(b) and 29, the movement may be performed when the rotation restricting member 103b or the rotation stopper 106b is operated toward the rotation restricting release position. The lowering detecting member 118 is provided at the position, and the scribe member 200 is lowered in conjunction with the releasing operation of the rotation restriction of the rotation restricting member 103b or the rotation stopper 106b.
另外,為了防止肥料的飛散或水的進入等,在前述施肥裝置17的肥料的貯存部的上部,以能夠開閉的方式設置轉動自如的給料斗蓋17a。在補充肥料時,打開該給料斗蓋17a向施肥裝置17供給肥料的結構。此時,也可以如圖29所示做成如下結構,亦即,設置若打開前述給料斗蓋17a則成為“接通”的敞開檢測開關121,若該敞開檢測開關121成為“接通”,則控制裝置100使前述切換致動器201致動,使劃線構件200下降。 In addition, in order to prevent the scattering of the fertilizer or the entry of the water, the hopper lid 17a that is rotatable is provided in an upper portion of the storage portion of the fertilizer of the fertilizer application device 17 so as to be openable and closable. When the fertilizer is replenished, the structure in which the hopper lid 17a is supplied with fertilizer to the fertilizer application device 17 is opened. In this case, as shown in FIG. 29, an open detection switch 121 that is "on" when the hopper lid 17a is opened may be provided, and if the open detection switch 121 is "on", Then, the control device 100 activates the aforementioned switching actuator 201 to lower the scribing member 200.
利用上述結構,在肥料的補充作業時,若打開給料斗蓋17a進行補充的準備,則劃線構件200自動下降並自動切換到使輔助裝載構件105移動的狀態,因此作業者不需要進行劃線構件200的下降操作,而提高作業效率。 According to the above configuration, when the hopper lid 17a is opened for replenishment during the replenishing operation of the fertilizer, the scribing member 200 is automatically lowered and automatically switched to the state in which the auxiliary loading member 105 is moved, so that the operator does not need to perform scribing. The lowering operation of the member 200 improves work efficiency.
在本發明的苗移植機中,設有作為驅動源的引擎210、從該 引擎210接受驅動力來變更機體的行駛輸出的大小、以及輸出方向的HST(hydrostatic transmission:液體靜壓動力傳動)211。該HST211如圖5等所示做成如下結構,亦即,藉由操作設置在引擎罩13上的行駛操作桿212,來對行駛輸出的大小以及輸出方向進行切換操作。 In the seedling transplanter of the present invention, an engine 210 as a drive source is provided, from which The engine 210 receives the driving force to change the size of the traveling output of the body and the HST (hydrostatic transmission) 211 in the output direction. The HST 211 is configured as shown in FIG. 5 and the like, that is, by operating the travel operation lever 212 provided on the hood 13 to switch the size of the travel output and the output direction.
此外,如圖29所示,該行駛操作桿212的操作也可以做成在行駛操作桿212與HST211之間設置由複數個構件構成的連動機構(省略圖示)的結構,也可以做成如下控制結構,亦即,設置檢測行駛操作桿212的操作角度的行駛電位計(potentiometer)213,將該行駛電位計213檢測出的操作角度發送到控制裝置100,使HST211的輸出軸旋轉的HST伺服馬達214致動,來變更HST211的輸出。 Further, as shown in FIG. 29, the operation of the travel operation lever 212 may be such that a linkage mechanism (not shown) including a plurality of members is provided between the travel operation lever 212 and the HST 211, and may be configured as follows. The control structure, that is, a potentiometer 213 that detects an operation angle of the travel operation lever 212, transmits an operation angle detected by the travel potentiometer 213 to the control device 100, and rotates the HST servo of the output shaft of the HST 211. The motor 214 is actuated to change the output of the HST 211.
