Abstract

PURPOSE:To prevent lodging of planted seedling and to plant seedlings in a surely protected state by designing position of a planting pawl part so as not to bury the planting pawl part in soil even at a buried position of planted seedling in soil and equipping the planting pawl part. CONSTITUTION:In a process wherein the root part of seedling P to be planted is buried in soil together with a guide beak 46 and reaches from a position F a little before a lower dead point to a position G somewhat apart from the position, an operation rod 45 is protruded by cam working, a planting beak 43 is widely opened and a grasped seedling P to be planted is released. Consequently, the seedling P to be planted is surely grasped until the seedling is buried into planting depth, released in a state where the seedling is buried in the planting depth and movement of the guide beak 46 becomes slowest so that bad planting can be prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for planting tape-shaped strawberry seedlings, etc. in a seedling transplanter for transplanting the seedlings to a landing. .

[Prior Art and Problems to be Solved by the Invention] Conventionally, when planting seedlings (transplanted seedlings) on a landing, for example, when this seedling is a rush seedling, the fungal strain grown in the nursery is dug up. The plants were harvested, and once they had about 10 new buds, they were hand-planted by selecting the seedlings one by one, but this process was time-consuming and required hard labor.

For example, Japanese Patent Laid-Open Publication No. 15610/1983 discloses a method for mechanically performing the planting and dividing of seedlings. However, in this method, the seedlings are forcibly torn off from the seedlings placed on the seedling stand using separating claws, and then transferred to the planting claws and planted on a landing.

However, with this method, the seedlings are forcibly and mechanically torn off from the clustered seedlings, so the new shoots may be damaged or parts without new shoots may be torn off. If the seedlings are poorly planted, the seedlings will not take root and wither. However, it is not possible to determine whether the seedlings are defective immediately after planting, and as mentioned above, the seedlings may die after planting. It is finally determined when the growth of new shoots is not observed after a while. However, at this point, it is already too late to plant, so supplementary planting is not possible, and the result is that the plants remain in a state of missing plants, resulting in a significant decrease in yield.

For this reason, when planting seedlings with sprouts that have been selected and divided in advance, it may be possible to support the seedlings with tape material and use the tape to plant the seedlings. However, when planting tape-cut seedlings from tape-cut mature seedlings, when the seedlings are taken out using claw means and planted on landings, the seedlings have already been divided into seedlings for each plant, so it is difficult to plant them. The attachment claw means need not be a scraping claw that forcibly scrapes off the block-shaped clustered seedlings, and a tool that simply grips the seedlings is sufficient. Therefore, if you do this, the planting will be done at the same time as the seedlings are planted in the muddy soil, and the planting will disturb the landing area by making holes in the muddy soil with the movement of the seedlings when they are released. As a result, there are problems such as insufficient planting and the seedlings lodging, and it is necessary to solve these problems.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has been devised for the purpose of providing a planting device using a seedling transplanter that can eliminate these drawbacks. In the seedling transplanter, the seedling transplanter is provided with a claw means, in which the seedlings are waited at the seedling feed-out opening provided at the lower end of the seedling stand, and the seedlings are taken out and planted on the landing. The claw means is used to grasp the seedlings and take them out while waiting for planting, and the claws are used to release the seedlings when they are immersed in the muddy soil and are planted. The planting part, which is planted in the muddy soil, is composed of a guide claw part that is immersed in the muddy soil together with the seedling, and the planting part is made up of a guide claw part that is set so that the planting part is not immersed in the muddy soil even when the seedling is immersed in the muddy soil. It is characterized by being provided in a set position.

According to the present invention, with this configuration, seedlings can be reliably planted using the claw means.

[Example] Next, an embodiment of the present invention will be explained based on the drawings. In the drawing, 1 is a riding type traveling aircraft for working in rice fields, and the present invention is implemented in the rear part of the traveling aircraft 1. A transplanting device 2 for rice seedlings planted in eight rows is attached so as to be able to move up and down.

rollers 19 and 20 are integrally provided on the sprocket shaft 18a and the sprocket shaft 18a, respectively. On the other hand, 21 is a drive body disposed on the gear 14 side of the seedling vertical feeding path 12, and both upper and lower ends of the drive body 21 are supported by the rollers 19 and 20 via eccentric shafts 19a and 20a. The driving body 21 is rotated by the rotation of the gear 14 in time with the movement of the aircraft.
The vertical feed claw 21a provided in the hole operates while drawing an arcuate trajectory A. Following this arcuate trajectory A, the vertical feed claw 21a moves to the side closer to the tape grown seedling 22 and closes the hole. 22b while being in a contact interference state, move to the end of the vertical feed (to the lower end of the slope), move the tape adult seedling 22 by one vertical feed pitch (the pitch of the seedling P for planting), and then The feed claw 21a is removed from the hole 22b and separated,
Then, the tape returns to the starting end side of the vertical feed, thereby performing intermittent vertical feeding of the tape seedlings. Further, a pair of blades 23 are integrally provided at the lower end of the drive body 21, and are adapted to move in the same arcuate trajectory A as the vertical feed pawl 21a.

On the other hand, a pair of sprockets 15b and 15c are provided on the gear shaft 15a of the gear 15 disposed on the other side of the seedling vertical feeding path 12.
The sprocket 15c is operatively connected to a sprocket 25 disposed above through a chino 26, and the sprocket 15c is operatively connected to a sprocket 27 disposed below through a chino 26. These sprockets are configured to rotate synchronously, but the gear shaft 15a and the upper sprocket shaft 25a
The eccentric shaft 28 is placed between the rollers 28 and 29 provided at
A drive body 30 is attached via the blades 29a and 29a, and operates in an arcuate locus B in the opposite direction to that of the drive body 21. A cutter 31 is integrally provided so as to face the.

The cutter 31 and the receiving blade 23 are connected to the vertical feed claw 21.
In conjunction with the movement of the tape adult seedlings 22 to enter the holes 22b, the tape adult seedlings 22 move closer to each other, and the tape adult seedlings 22
While the cutter 31 is being fed vertically, the cutter 31 cuts the tape material 2 in such a state that the central cutting edge of the cutter 31 enters the hole 22b of the tape material, which is supported by the receiver blade 23.
2a is cut, and the receiver is configured to enter between the blades 23, so that the tape adult seedlings 22 are set to receive the cutting action of the tape material while being subjected to the vertical feeding action.

Further, a rotating arm 33 is attached to the lower sprocket shaft 27a.
is provided. On the other hand, a crank arm 34 is pivotally supported on the seedling mounting table 8, and the base end of a seedling feeding arm 35 is pivotally supported at the distal end of the crank arm 34. The seedling feeding arm 35 has a connecting plate 33a in the middle.
The seedling feeding arm 35 is connected to the rotary arm 433 via the rotary arm 433, and its tip is positioned below the cutter 31. However, the seedlings P cut and separated by the cutter 31 are
The seedling tray 8 is configured to send the seedlings to the side of the seedling feed-out port 8a provided at the lower end of the seedling stand 8 at the same time. The sent seedlings are held in the body 36 by a flexible seedling holder formed by whiskers protruding from both sides so that the lower half of the seedlings closes the seedling feeding port 8a so as not to fall off. However,
Further, at this time, during planting, the upper side of the seedling P is held by a seedling guide 37. This seedling guide 37 has a substantially U-shape with an open end in the vertical feeding direction of the seedlings, and serves as a support guide for the seedlings P when planting is fed vertically. The seedling P is planted at an early stage on the vertical feed start end side of the position 31 before being cut. And seedling feeding arm 3
The seedlings P sent by 5 are planted through the seedling feeding port 8a.
The root side of the seedling holder is temporarily held by the body 36, and the tip side is temporarily held by the seedling guide 37, and in this position, the planting described later is supplied to the beak 43 side. Incidentally, this seedling feeding arm 35 is formed with two protruding upper and lower feeding arms, and when planting the seedling P with the tape material 22a in between, it feeds both the upper and lower sides of the seedling P. The feed arm on the side) is short, and consideration is given to avoid interference with the beak 43 during planting, which will be described later.

In the figure, reference numeral 38 denotes a guide plate that guides the tape grown seedlings 22 from above the position of the vertical seedling feeding section 10 in a pinching manner from both left and right sides. A through hole 38a and a through groove 38b are formed. Further, a base end portion of a surface holder 38c formed by an elastic plate is fixed to the left guide plate 38, but the surface holder 38c is used more than necessary as the tape grown seedlings 22 are subjected to a vertical feeding action. This is to elastically hold and support the object so that it will not be transferred or its posture will be disturbed.

Reference numeral 40 indicates a claw device for planting provided in the gear case 6 so as to correspond to each city feeding port 8a;
is formed using a planter case 41 set in the same configuration as that of a general-purpose rice transplanter, but a bracket 42 that is approximately U-shaped in plan view is integrally provided at the tip of the planter case 41. Furthermore, insertion grooves 42a are provided on both left and right sides of the lower end of the bracket 42. On the other hand, 43 is a pair of beaks that grips the seedling P from both sides;
The tips are plate-shaped, and a sponge material 44 is adhered to the inner surfaces (gripping surfaces) facing each other. In this planting, the base end of the beak 43 has a boss portion 43a and an actuation plate 4.
3b are integrally formed. And the pair of plants is Beak 43.

Either one of the insertion holes 42 corresponds to the actuation plate 43b.
The two boss portions 43b are pivotally supported on the bracket 42 by front and rear pins 43c so as to be able to swing freely, with the two boss portions 43b being passed through from the inside of the bracket 43a.

On the other hand, the planter case 41 is provided with an operating rod 45 that is set to appear and retract by cam operation linked to the circulation movement for planting. The upper end of 46 is integrally attached.

A locking portion 46a is formed at the upper end of the guide beak 46. The locking portion 46a locks the tip of the penetrating actuation plate 43b. And the nail device 40 is used for planting.

During planting, the operating rod 45 protrudes from the planter case 41 on the trajectory in which the beak 43 moves beyond the bottom dead center and toward the top dead center.
3c as a fulcrum, the actuating rod 45 moves from the D position slightly before reaching the top dead center to the E position beyond the top dead center, causing the actuating rod 45 to move toward the planter case 41. The operating plate 43b is swung upward, and the planting beak 43 is swung so that the distance between the seedlings P and the beak 43 becomes narrower. Grasp the tape material 22a, and for planting, take out the seedling P from the seedling outlet 8a and move it down toward the bottom dead center. The seedling P is planted together with the guide beak 46 when the root part of the seedling P is immersed in the mud, and the operating rod 4
5 protrudes by cam operation and the beak 43 expands during planting.

The gripped planting involves releasing the seedling P, but in this planting the beak 43 is positioned so that it will not sink into the mud even when it reaches the bottom dead center. on the other hand,
Regarding the guide beak 46, in the running trajectory where the seedling is pulled out of the mud from the bottom dead center position, when planting seedlings immersed in the mud, the seedlings should be firmly planted by pressing them against the front wall of the hole. In order to prevent it from collapsing, it is displaced forward in the direction of the aircraft's movement from the bottom dead center position.

In the embodiment of the present invention configured as a slow speed tape seedling 22, the tape material 22a is intermittently vertically fed one pitch at a time by the vertical feeding operation of the vertical feeding claw 21a that is timed with the running of the machine. The seedlings P that have been cut will be gripped by the claw device 40 and will be planted on the landing.

In this device, the seedlings P are tape-cut, sent to the seedling feed-out port 8a, and waiting there for planting.The tape material 22a is held between the beaks 43 and
And it will be rolled out from here. Therefore, the beak 43 does not come into direct contact with the seedling P during planting, but receives an indirect gripping action via the tape material 22a, so even if the gripping force is strong, it is effectively protected. As a result, healthy planting will allow seedlings P to be planted. This means that the amount of seedlings P during planting is not constant due to manual division, and thick planting is particularly effective when the seedlings P are grabbed. When the seedling P is released during planting, the beak 43 will not be caught on the tape material 22a, and the posture of the seedling P will not be disturbed.

Moreover, in this planting, the beak 43 reaches the bottom dead center near the muddy soil area without penetrating into the muddy soil, and then releases, so the beak 43 releases its grip in time with the planting of the seedling P. Even if it opens horizontally as much as possible, 01
When planting seedlings in the i-field, there are no large holes in the site, and as a result, the transplanted seedlings do not have problems such as the seedlings P being insufficiently planted and falling over, and the seedlings are planted in an orderly manner. You will be able to work.

Moreover, in this case, when the seedling P is immersed in the mud during planting, the guide beak 46 is also immersed in the mud.
Even if the beak 43 does not enter the muddy soil during planting, the guide beak 46 protects the seedlings and there is no problem. Moreover, the guide beak 46 moves downward almost in time with the immersion into the muddy soil, and the planting is immersed deep into the muddy soil before the seedlings P, so the planting has the advantage that the seedlings can be further protected. Yes. At the stage when the seedling P reaches approximately the bottom dead center, the planting beak 43 opens and the grip on the seedling P is released. The grip is held firmly until the plant is immersed in the water, and it is released when the planting is almost immersed to the depth and the movement of the guide beak 46 is at its slowest. Planting in a way that prevents the plant from immersing itself in the soil has the advantage of preventing defects from occurring.

[Operations and Effects] In short, the present invention is configured as described above, so the seedlings are planted waiting at the seedling dispensing opening, and the seedlings are taken out by the claws and planted on the landing. , Since the planting claw part does not get into the mud even if the seedlings are immersed in the mud, the landing area will not be disturbed even if the opening operation is performed at the same time as planting the seedlings in field II. ,
Moreover, during planting, the seedlings are immersed in the mud while being protected by guide claws that are immersed in the mud.As a result, the seedlings are prevented from lodging and are planted. Since the seedlings are planted in a manner that ensures their protection, the planting can greatly contribute to improving performance.
