  The present invention relates to a harvester for leaf vegetables such as spinach and komatsuna.

  Various harvesters have been proposed for the purpose of improving the efficiency of harvesting leafy vegetables such as spinach and Japanese mustard. For example, a transport device is provided that lifts the leaf part that is raised and arranged on the front side of the aircraft from both sides, cuts the roots in the soil with a cutter provided at the front end of the aircraft, and pulls the spinach with the transport device while lifting the spinach.

Japanese Patent Laid-Open No. 7-135831 JP-A-9-107765 JP 2001-346429 A JP 2005-304446 A JP 2009-142227 A JP 2014-166175 A

  For harvesters of leafy vegetables such as spinach, it is required to be able to harvest efficiently and harvest without damaging soft leaves. However, a conventional harvesting machine that picks up and harvests leaf-cut vegetables by sandwiching them with a conveyor is difficult to use when the leaf vegetables are not aligned and grown in the field. The problem is that the varieties that can be harvested are limited to upright, and the varieties that hang on the ground cannot be harvested.

  Therefore, in order to solve the above problems, a leaf vegetable harvesting machine has been developed that can efficiently and reliably harvest leaf spinach and other leaf vegetables in the soil without root damage. (Patent Document 6).

  However, further research has revealed that the following problems can occur in the harvesting machine disclosed in Patent Document 6 described above. Specifically, as shown in FIG. 6, when transporting, the rooted leaf vegetables are placed on a conveyor that sequentially moves at high speed, transported one by one, and stored in a container. At this time, the leaf vegetables are placed in a state of lying on the conveyor, which causes the soil present on the conveyor to adhere to the leaves. Leafy vegetables need to be washed with water when shipped as a product after harvesting, but the more soil adhering to the leaves, the longer it takes to wash, and the cost increases due to the use of a large amount of water. The problem which causes the damage of the leaf by washing with water may arise.

  Also, since it is stored in the container so that it falls and stacks, it is easy to cause damage such as bending of leaves, and it is stacked in the container in a disassembled state, so it is necessary to align the direction when taking out, shipping work There may be a problem that the time is increased.

  The present invention has been made in view of the above circumstances, and provides a leaf vegetable harvesting machine that can prevent soil from adhering to leaves when conveying rooted leaf vegetables and that can be taken in an aligned state. The purpose is to provide.

  The present invention solves the above-described problems by the solving means described below.

  A leaf vegetable harvesting machine according to the present invention is a leaf vegetable harvesting machine provided with a root cutting blade for rooting leaf vegetables by entering the ground of a farm field into a machine body having a power source and capable of traveling, It has an endless transport section that is placed immediately after the traveling direction with respect to the root cutting blade and places and transports the rooted leaf vegetables, and the moving speed of the transport section is higher than the traveling speed of the airframe. A structure having a conveyor set at a low speed, and the transport unit has a first support member that is bridged in a direction orthogonal to the moving direction and arranged at a predetermined interval in the moving direction, or the first In addition to the support member, it is necessary to provide a structure having second support members that are bridged between the adjacent first support members and that are disposed at a predetermined interval in the direction orthogonal to the moving direction.

  ADVANTAGE OF THE INVENTION According to this invention, when conveying rooted leaf vegetables, the leaf vegetable harvesting machine which can prevent that soil adheres to a leaf and can take in in an aligned state is realizable. Therefore, problems that may occur in the conventional apparatus, such as soil adhering to the leaves when leaf vegetables are placed and transported in a state lying on the conveyor, and when stored in a container or the like after the transportation, it becomes scattered. It is possible to solve the problem.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view (schematic diagram) showing an example of a leaf vegetable harvesting machine 1 according to an embodiment of the present invention. 2 is a partially enlarged view (schematic diagram) of the harvester 1 in a plan view, and FIG. 3 is a partially enlarged view (schematic diagram) of the harvester 1 in a side view. FIG. 4 is a perspective view (schematic diagram) showing an example of the conveyor 22 in the harvesting machine 1. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiments, and the repetitive description thereof may be omitted.

  The leaf vegetable harvesting machine 1 includes a crawlers 10a and 10b, a self-propelled machine body 12 including an engine 34 that drives the crawlers 10a and 10b, and a harvesting mechanism section that roots and harvests leaf vegetables grown in a field. Is provided. On the upper part of the machine body 12, a control unit 30 for controlling the operation of the harvesting mechanism unit and a battery box 32 for driving an electric motor or the like are provided. An operation handle 13 is provided at the rear part of the machine body 12, and the operation handle 13 is used to operate the traveling direction, the traveling speed, the harvesting mechanism unit, and the like of the machine body 12. The engine 34 is disposed at a rear position of the airframe 12 below the operation handle 13.

  The harvesting mechanism unit includes a machine frame 14 that extends forward from the machine body 12, a tilt drive unit 16 that is supported by the machine frame 14, and a tilt that is supported by the front part of the machine frame 14 so as to be tiltable in a vertical plane. A frame 18, a root cutting blade 20 attached to the lower end portion of the tilting frame 18, and a conveyor 22 disposed behind the root cutting blade 20 are provided.

  As shown in FIGS. 1 to 3, the tilt drive unit 16 includes a drive unit body 16b including a drive rod 16a that is driven to extend and contract, and is pivotally supported on the upper portion of the machine frame 14 via a shaft 16c. The front end is pivotally supported on the upper part of the tilting frame 18.

  Further, the tilting frame 18 includes a support frame 18a that is pivotally supported on the front end of the machine frame 14 via a shaft 18c, and a lifting frame 18b that is supported movably on the support frame 18a. The support frame 18a tilts with respect to the traveling direction of the machine body 12 with the shaft 18c as a fulcrum, and the elevating frame 18b tilts together with the support frame 18a. The support frame 18a is provided with an adjusting unit 19 that adjusts the height position of the elevating frame 18b. The elevating frame 18b is moved up and down by adjusting the support position by the support frame 18a.

  According to said structure, the effect | action which tilts (swings) the tilting frame 18 with respect to a running direction is obtained by driving the drive rod 16a to extend and contract. An electric motor, a hydraulic mechanism (a hydraulic pump and a hydraulic cylinder), or the like can be used as a drive source provided in the drive unit main body 16b to drive the drive rod 16a to extend and contract (not shown).

  Further, the root cutting blade 20 is fixed so as to span between the lower ends of the tilting frame 18 (the lifting frame 18b). As an example, the root cutting blade 20 used in the harvesting machine of the present embodiment has a width of 10 [cm] in the traveling direction, a full width (width in a direction orthogonal to the traveling direction) of 100 [cm], and a thickness of about 10 [mm]. It is made of a plate of carbon tool steel, and the harvesting width is in a range outside the arrangement width of the crawlers 10a, 10b.

  In the present embodiment, the front edge (about 5 [cm] width) of the root cutting blade 20 is inclined so that the front side gradually becomes lower so that it can easily enter the ground of the field. The root cutting blade 20 has an action of cutting the roots of leaf vegetables while moving through the ground, and an action of lifting the leaf vegetables having the roots cut from the ground to the surface side. The front edge of the root cutting blade 20 is sharply formed so that the roots of leaf vegetables can be cut.

  At a position close to the rear edge of the root cutting blade 20, it is slightly spaced from the upper surface of the root cutting blade 20 (interval 5 [cm]), and a root pushing rod 24 is disposed in parallel with the root cutting blade 20. The root pushing rod 24 is fixed so as to be bridged between the tilting frames 18b. According to this, while the leaf vegetables that are rooted by the root cutting blade 20 and lifted to the surface side are further lifted to the ground surface side, the root push rod 24 hits the vicinity of the root of the lifted leaf vegetables and the upper side of the leaves is the conveyor 22. The effect that leaf vegetables are defeated so that it may turn to the side is acquired.

  As shown in FIGS. 1 to 3, the conveyor 22 has a front end on the ground surface slightly higher in the height direction than the root cutting blade 20 behind the root cutting blade 20 (backward with respect to the traveling direction of the machine body 12). Arranged so that the edge is located. According to this, the action which lifts and conveys the leaf vegetables lifted to the ground surface side by the root cutting blade 20 and the root pushing rod 24 which advance in the ground by the conveyor 22 arrange | positioned on the ground surface is acquired.

  Here, the conveyor 22 will be described in detail. The conveyor 22 according to the present embodiment has a two-stage configuration of a first conveyor 22A and a second conveyor 22B. However, the present invention is not limited to this configuration, and may be a one-stage configuration or a three-stage configuration (not shown).

  Each of the first conveyor 22A and the second conveyor 22B is mounted such that endless transport sections 22Aa and 22Ba are wound around rollers (or pulleys, gears, etc.), respectively. By rotating and driving the roller with power, the endless transporting portions 22Aa and 22Ba are circulated and moved, and the leaf vegetables are sequentially placed and transported.

  The first conveyor 22 </ b> A is provided behind the root cutting blade 20 (backward with respect to the traveling direction of the machine body 12) and at a slightly higher position in the height direction than the root cutting blade 20. In order to make it easier to transfer the leaf vegetables, the conveying portion 22Aa is inclined so that the front end edge (on the root cutting blade 20 side) of the first conveyor 22A is at a low level. By bringing the front side of the conveyor 22 close to the ground surface, leaf vegetables can be prevented from being picked up.

  The second conveyor 22B is provided behind the first conveyor 22A (backward with respect to the traveling direction of the machine body 12), and is conveyed so that the front edge (the first conveyor 22A side) of the second conveyor 22B is low. The portion 22Ba is inclined. Furthermore, the arrangement is such that the front edge of the second conveyor 22B is lower than the rear edge of the first conveyor 22A, and the front edge of the second conveyor 22B and the rear edge of the first conveyor 22A are spaced apart. (As an example, the separation distance is about 20 [mm]). That is, the rear end edge of the first conveyor 22A and the front end edge of the second conveyor 22B are separated in the height direction and at the same time in the longitudinal direction of the traveling direction.

  The reason why the rear end edge of the first conveyor 22A and the front end edge of the second conveyor 22B are separated is that when the collected leaf vegetables are transferred from the first conveyor 22A to the second conveyor 22B, the leaf vegetables This is to remove the soil adhering to the soil.

  Here, as a characteristic configuration of the present embodiment, the moving speed of the transport units 22Aa and 22Ba of the first conveyor 22A and the second conveyor 22B is lower than the traveling speed of the machine body 12 (moving speed of the crawlers 10a and 10b). Is set to

  According to this, while the machine body 12 travels, the leaf vegetables are sequentially rooted and lifted onto the conveying portion 22Aa of the first conveyor 22A. At this time, since the traveling speed of the machine body 12 (moving speed of the crawlers 10a and 10b) is relatively fast and the moving speed of the transport section 22Aa of the first conveyor 22A is relatively slow, the first row lifted first is excluded. Then, the leafy vegetables from the second row are lifted and pressed to the place where the conveyance in the front row is staying. Further, the row is then lifted and pressed. That is, when focusing on one row to be harvested, the front row and the back row are pressed against each other, compressed to a denser state than the planting interval in the field (planting interval in the running direction), and in an aligned state while standing It can be transported. Therefore, in the conventional device, the problem is that soil is deposited on the leaf while lying on the conveyor at the time of conveyance, or the leaf is damaged by being stored in the container in a disassembled state, and the removal work It is possible to solve the problem of taking time and effort.

  In the present embodiment, the moving speed of the transport unit 22Ba of the second conveyor 22B is set to the same speed as the moving speed of the transport unit 22Aa of the first conveyor 22A. However, it is not limited to this. As another example, when the moving speed of the transport section 22Ba of the second conveyor 22B is set to be lower than the moving speed of the transport section 22Aa of the first conveyor 22A, the rooted leaf vegetables are the first conveyor. The above-mentioned effects are obtained at the stage where the sheet 22A is lifted onto the conveying part 22Aa of 22A, and the leaf vegetables are transferred from the conveying part 22Aa of the first conveyor 22A onto the conveying part 22Ba of the second conveyor 22B. Thus, the effect of being compressed into a state in which the alignment interval is closer is obtained.

  Here, the configuration of the transport unit 22Aa of the first conveyor 22A and the transport unit 22Ba of the second conveyor 22B will be described. Each of the transport units 22Aa and 22Ba according to the present embodiment includes a first support member 22Ab and 22Bb that are spanned in a direction orthogonal to the moving direction and arranged at a predetermined interval in the moving direction (parallel bar structure). Is formed. As an example, the first support members 22Ab and 22Bb are formed using rod-shaped members having a circular cross section. However, it is not limited to this structure, You may comprise using a rod-shaped member or plate-shaped member with a polygonal cross section.

  According to this, the first support members 22Ab and 22Bb are arranged at predetermined intervals in the moving direction, so that the groove portions 22Ac and 22Bc are formed between the adjacent first support members 22Ab and between 22Bb, respectively. It is formed. Therefore, when lifting rooted leaf vegetables, the roots are hooked into the groove portions 22Ac and 22Bc to be surely lifted, and the roots are dropped into the groove portions 22Ac and 22Bc and placed in an aligned state. In addition, it is possible to carry the sheet so as not to be displaced downward even when the inclination angle is given.

  At this time, the disposition interval L1 between the adjacent first support member 22Ab and the first support member 22Ab and the disposition interval L2 between the adjacent first support member 22Bb and the first support member 22Bb are all leafy vegetables in the field. It is preferable that the length is set to be smaller than the planting interval (planting interval in the traveling direction) L3.

  According to this, on the transport unit 22Aa of the first conveyor 22A and the transport unit 22Ba of the second conveyor 22B, the compressed space is compressed to a state denser than the planting interval in the field (planting interval in the traveling direction). With respect to leafy vegetables in which the alignment interval (alignment interval in the running direction) is narrow, it becomes possible to support more by dropping more root portions into the groove portions 22Ac and 22Bc.

  In addition to the first support members 22Ab and 22Bb, as a modification of the transport unit 22Aa of the first conveyor 22A and the transport unit 22Ba of the second conveyor 22B, between the adjacent first support members 22Ab and 22Ab and between 22Bb and 22Bb It is also possible to form a structure having a second support member (not shown) that is spanned by a predetermined distance in the direction perpendicular to the moving direction, that is, a lattice structure or a mesh structure. The same effect as the said structure (parallel bar structure) can be acquired also by the said structure.

  In the present embodiment, the electric motor 36 is used as a power source for moving the transport units 22Aa and 22Ba of the first conveyor 22A and the second conveyor 22B. As an example, the control unit 30 may change the output of the electric motor 36 to variably control the moving speeds of the transport units 22Aa and 22Ba.

  Or as a modification, it is good also as a structure which uses a hydraulic motor (not shown) as a motive power source which moves conveyance part 22Aa, 22Ba of 1st conveyor 22A and 2nd conveyor 22B. As an example, the moving speed of the transport units 22Aa and 22Ba may be variably controlled by changing the amount of oil that the control unit 30 passes through the hydraulic motor. As a method of changing the oil amount, a method for controlling the output of a hydraulic pump (not shown) or a control valve (not shown) provided in a piping path from the hydraulic pump to the hydraulic motor is controlled. Or the like can be used.

  Alternatively, as another modified example, an internal combustion engine (engine 34), which is a power source for running the machine body 12, is commonly used as a power source for moving the transport units 22Aa and 22Ba of the first conveyor 22A and the second conveyor 22B. Also good. As an example, the control unit 30 may be configured to control so as to be a predetermined speed set in advance corresponding to the rotational speed of the engine 34, that is, corresponding to the traveling speed of the crawlers 10a and 10b.

  Incidentally, both the inclination angle of the conveyance surface of the conveyance unit 22Aa of the first conveyor 22A with respect to the ground and the inclination angle of the conveyance surface of the conveyance unit 22Ba of the second conveyor 22B with respect to the ground may be set as appropriate. When configured as a fixed-angle type, as an example, different angles may be set so that the inclination angle of the first conveyor 22A is about 15 [°] and the inclination angle of the second conveyor 22B is about 30 [°]. As another example, the inclination angle of the first conveyor 22A and the second conveyor 22B may be set to the same angle so that both are about 30 [°].

  Alternatively, when configured as an angle variation formula, the tilt angle of the first conveyor 22A may be varied to about 10 to 15 [°] according to the tilt angle of the tilt frame 18 that performs the tilt operation. The mechanism for changing the angle is configured such that the front end portion of the first conveyor 22A is connected to the lower end of the tilting frame 18 to change the angle by a mechanical interlocking operation, or the tilting frame 18 is mechanically connected. First, a mechanism for changing the angle of the first conveyor 22A is provided separately, and the tilt angle of the tilt frame 18 is sensed, and the control unit 30 can change the angle (not shown).

  Furthermore, as a characteristic configuration of the present embodiment, a pair of guide plates 38 a and 38 b are provided upright at positions above both ends of the root cutting blade 20. At this time, the entire width of the root cutting blade 20 (width in the direction orthogonal to the traveling direction) is relatively long, and the entire width of the transport portion 22Aa of the first conveyor 22A (width in the direction orthogonal to the moving direction) is relatively short. In addition, the guide plates 38a and 38b have a front end portion in the traveling direction that is the same as or outward from the side end portion of the root cutting blade 20, and a rear end portion in the traveling direction that is the conveying portion 22Aa of the first conveyor 22A. It is arrange | positioned so that it may become the same position or inward position as the side edge part.

  According to this, leaf vegetables that are sequentially rooted and lifted onto the conveying portion 22Aa of the first conveyor 22A pass between the pair of guide plates 38a and 38b, thereby causing the traveling direction (conveying) Plant 22Aa in the direction perpendicular to the traveling direction and the width between the full width of the root cutting blade 20 in the direction orthogonal to the moving direction of the portion 22Aa and the width of the conveying portion 22Aa. Compressed to a state denser than (interval), and can be conveyed while standing and aligned. Therefore, in combination with the above-described configuration, in the moving direction and the orthogonal direction of the conveying units 22Aa and 22Ba, it is possible to realize conveyance in a state where the conveying unit 22Aa and 22Ba are compressed and densely arranged in a standing state. The problem can be solved more reliably.

  On the other hand, the accommodating part 40 which accommodates the leaf vegetables conveyed by the 2nd conveyor 22B is provided in the upper part of the body 12 behind 2nd conveyor 22B. According to this, leafy vegetables can be accommodated in the accommodating part 40 and collect | recovered sequentially. As a modification, a configuration may be adopted in which a container or the like is arranged in the accommodating portion 40 (not shown).

Then, the effect | action which harvests leaf vegetables with the harvester 1 which concerns on this embodiment is demonstrated.
The harvesting machine 1 drives the crawlers 10a and 10b to move (advance) the machine body 12 and performs root cutting of the leaf vegetables with the root cutting blade 20 that has entered the ground, and lifts and conveys the vegetables to the conveyor 22 for transportation. The operation of accommodating in the accommodating portion 40 is performed. In FIG. 5, the harvesting operation | movement from root cutting of leaf vegetables by the harvester 1 to conveyance is shown typically.

  First, by driving the crawlers 10a and 10b and moving the machine body 12 forward, the root cutting blade 20 sequentially roots leafy vegetables. At this time, it is preferable to advance the machine body 12 while tilting (swinging) the tilting frame 18 by driving the drive rod 16a of the tilting drive unit 16 to extend and contract.

  That is, the root cutting blade 20 fixed to the tilting frame 18 is tilted (oscillated). According to this, when there are obstacles such as stones in the ground, the method of moving the root cutting blade 20 horizontally only pushes the obstacles forward and the obstacles cannot be avoided. While this results in hindrance to cutting, it acts to push the obstacle up and down, making it less likely to be affected by the obstacle. Therefore, the accumulation of soil accompanying the advance of the root cutting blade 20 is suppressed, and the root cutting operation of leaf vegetables can be performed smoothly.

  Next, the leaf vegetables rooted with the root cutting blade 20 are lifted to the surface side by the root push rod 24. Furthermore, it is lifted by the transport unit 22Aa of the first conveyor 22A that circulates and is placed on the transport unit 22Aa to start transport.

  At this time, since the traveling speed of the machine body 12 (moving speed of the crawlers 10a and 10b) is relatively fast and the moving speed of the transport section 22Aa of the first conveyor 22A is relatively slow, the first row lifted first is excluded. Then, the leafy vegetables from the second row are lifted and pressed to the place where the conveyance in the front row is staying. Further, the row is then lifted and pressed. Therefore, in the traveling direction, it is compressed to be denser than the planting interval in the field, and can be transported in an aligned state while standing.

  In addition, the leaf vegetables have the front end in the running direction being the same as or outward from the side end of the root cutting blade 20, and the rear end in the running direction being the same as the side end of the transport section 22Aa of the first conveyor 22A. Alternatively, by passing between a pair of guide plates 38a, 38b arranged to be inward positions, the width of the entire width of the root cutting blade 20 is changed to the width of the entire width of the conveying portion 22Aa. It will be in a state of being pressed. Therefore, in the direction orthogonal to the traveling direction, the compressed space is compressed to be denser than the planting interval in the field, and it is possible to carry the vehicle while standing and aligned.

  In the conveyance process, the rear end edge of the first conveyor 22A and the front end edge of the second conveyor 22B are arranged apart from each other by a predetermined distance (about 20 [mm]), so the conveyance unit 22Aa of the first conveyor 22A. When leaf vegetables are transferred from the top onto the transport section 22Ba of the second conveyor 22B, the action of dropping the soil attached to the vicinity of the roots can be obtained without dropping the leaf vegetables.

  In addition, since the conveyance section 22Aa of the first conveyor 22A and the conveyance section 22Ba itself of the second conveyor 22B also have the above-described grooves 22Ac and 22Bc, the effect of dropping the soil attached to the leaf vegetables during the conveyance is obtained. Can do. Furthermore, the roots are hooked into the groove portions 22Ac and 22Bc to be surely lifted, and the roots are dropped into the groove portions 22Ac and 22Bc so that they can be placed in an aligned state. It is possible to carry the sheet so as not to slip down.

  The leafy vegetables conveyed by the conveyance unit 22Ba of the second conveyor 22B reach the accommodation unit 40 provided in the upper part of the machine body 12 behind the second conveyor 22B. At this time, since the leaf vegetables are in a state of being densely compressed and aligned while standing, it is possible to perform the operation of collecting them in a container or the like very easily and without damaging the leaves.

  In this way, since the leafy vegetables are not placed in a state lying on the conveyor while reaching the storage unit 40 after being rooted, the soil existing on the conveyor is attached to the leaves. Can be resolved. Therefore, when washing with water for shipping as a product after harvesting, the time for washing with water can be shortened, so that costs can be reduced and leaf damage caused by washing with water can be prevented.

  As described above, according to the leaf vegetable harvesting machine according to the present invention, when transporting the rooted leaf vegetables, it is possible to prevent soil from adhering to the leaves and to take them in an aligned state. It becomes possible. Therefore, the problem that can occur in conventional harvesting machines due to the leafy vegetables being placed on the conveyor and soil being attached to the leaves, that is, it takes time to wash the water when shipping, By using this water, the cost increases, and further, it is possible to solve the problem of causing leaf damage due to washing with water.

  In addition, since the harvesting operation is not performed such that the rooted leaf vegetables are sandwiched and lifted by a conveyor, it can be harvested without damaging the soft leaf vegetables, and it can be dropped in a conventional harvesting machine. Since they are stored in the container so that they are stacked, the leaves are likely to be bent and bent, and they are stacked in the container in a disassembled state. This makes it possible to solve problems such as

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the present invention. In particular, soy leafy vegetables such as spinach and komatsuna are assumed as leafy vegetables, but it can be similarly applied to vegetables other than leafy vegetables or flowers that are harvested by root cutting. is there.
