Description

[Detailed description of the invention] [Industrial application field]

The present invention is a transplanter or a seedling processing device that uses seedlings grown in a seedling container such as a paper cylinder seedling container that is connected in an orderly manner so as to be separable into individual seedlings in the transplant cultivation of agricultural products. This invention relates to a separation device for separating individual seedlings.

[Conventional technology]

As shown in Japanese Patent Publication No. 50-21923, a separating device that sequentially separates a group of aligned seedlings, such as paper tube seedlings, into individual seedlings is a rotary type having a plurality of stepped sections corresponding to each row of seedlings. It has been proposed to separate and fall using a feeding body made of a disc body. Further, Japanese Patent Publication No. 63-50962 proposes a separation device using a plurality of rotating rolls that press against the moving front surface of the seedlings to be separated in a moving group of aligned seedlings.

[Problems to be solved by the invention]

In the conventional technique using a rotary disc body having a step section, the seedlings are separated from the arranged seedlings in a direction perpendicular to the surface thereof, and the paper tube seedling growing container is open at the top and bottom.
During the seedling-raising period, the paper that forms the paper cylinder seedling-raising container rots and its strength decreases, but its connection strength is maintained, so if you try to separate it from the vertical direction, the paper of the seedling-raising container will tear. Separation errors may occur during separation, and the seedlings left behind may become an obstacle to the next separation, resulting in successive separation errors. In addition, in the method using a plurality of rotating rolls, the separated seedlings are simply knocked over, so the heights and directions of the seedlings are scattered, and it requires manpower to align the seedlings, which is inefficient. Further, the seedlings are not separated one after another, but a large number of seedlings are separated in various directions at a time, so this device cannot be used in a transplanter. The present invention solves the above-mentioned problems, and uses a separating device that reliably separates seedlings from side to side, and even after separation, feeds them out as a lined row of seedlings. The aim is to provide equipment and dramatically expand transplant cultivation.

[Means to solve the problem]

The separating device according to the invention of claim 1 is arranged to separate seedlings 40 from a group of arranged seedlings grown in a seedling growing container 42 which is connected to the seedlings 41 in an orderly manner so as to be separable into individual seedlings 41.

Two shafts 22.23 are provided below the lateral movement mechanism frame 21 and are long (at the same height) in the direction of movement. In addition, although not shown, the shaft 23 is carved with a cylindrical cam in which a forward groove and a backward groove are formed in an endless intersecting shape, which is known in rice transplanters, etc., and a projection (not shown) provided on the lateral movement mechanism frame 21 is formed. When the shaft 23 rotates, the lateral movement mechanism frame 21 moves back and forth continuously in the lateral direction, and the movement speed is slower than the outer circumferential speed of the rollers 1 and 2.
In the embodiment, it is about 1/3 of that. In front of the roller 1.2, a pair of belts 5.7 are attached to the seedlings 4.
A vertical movement mechanism 30 is provided to move the group of aligned seedlings 40 in the vertical direction of one conveyance direction. The vertical movement mechanism 30 is provided with a vertical movement mechanism frame 31 that is substantially rectangular in plan view, and a pair of longitudinally long seedling guide bodies are provided on the left and right upper sides of the vertical movement mechanism frame 31 at intervals slightly wider than the width of the lined seedling group 40. 32 is provided. Then, the aligned seedling group 40 is placed on the vertical movement mechanism 30 and is intermittently moved in the vertical direction at the left and right moving ends of the lateral movement mechanism 20.

A belt 33 having a width slightly narrower than the width of the lateral movement mechanism frame 21 is passed between the belts 5 and 5. The pulley 34 rotates at the moving end of the lateral movement mechanism 20 so as to intermittently move one row of seedlings in the group of aligned seedlings 40 in the direction of the rollers 1.2. Next, the operation will be explained. The lateral movement mechanism 20 of the seedling separation device has a predetermined movement end,
A group of aligned seedlings 40 is placed on a belt 33 serving as a vertical movement mechanism 30, and is fed to a position where the front end of the group of aligned seedlings 40 comes into contact with a seedling regulating body 13 on the roller 1 side serving as a first rotating body. At this time, the front end of the roller 1 as the first rotating body is in contact with the front end of the foremost row of the sorted seedling group 40, and the front end of the roller 2 as the second rotating body is in a position touching the front end of the first row of the sorted seedling group 40. It should be at almost the same position as the front end. When the shafts 3, 4, 9, 10, and 23 are rotated by appropriate means, the lateral movement mechanism frame 21 moves in the lateral direction, and the rollers 1.2, belts 5, 7, and seedling regulating body 13.14 are integrally moved. , and the roller 1°2 and belt 5.7 rotate. As a result, the seedling rows 41a of the aligned seedling group 40 are separated.
, 41b, 41c, .
The front ends of the two rotate as they touch each other. At this time, the rotating direction of the roller 1 is such that the side of the roller 1 that contacts the side surface of the seedlings 41a to be separated rotates in the opposite direction to the moving direction of the roller 1, and its outer peripheral speed is faster than the moving speed of the roller l. Therefore, a force is applied from the roller 1 to the seedlings 41a to be separated in the same plane as the surface of the group of aligned seedlings 40, and the seedlings 41a to be separated try to rotate within that plane, and the seedlings next to the separated seedlings Seedling 41b
The seedling growing containers 42 are successively uncoupled from their ends, and the seedlings 41 with their connections peeled off are sandwiched between the following seedling row and the roller 1 and rolled. Also, since the seedlings 41a to be separated are rolled in the opposite direction to the rotation direction of the roller 1, the seedlings 41b next to the seedlings to be separated are separated.
Because it is connected to the next seedling 41c and the following seedling row, it is impossible to rotate in the same direction as the seedling 41a to be separated. Seedling 41 following the seedling to be peeled off and separated from the front end
The seedlings b are not pulled out while being connected to the seedlings 41a to be separated (and are reliably separated). The separated seedlings 41 contact the roller 2, which is a second rotating body, and are rotated in the opposite direction to the roller 1. The separated seedlings 41.a, which were not separated by the roller 1, also come into contact with the roller 2. Then, the seedlings 41 are separated by being rolled in the opposite direction to the rollers 1 by the rollers 2.The seedlings 41, which are picked up and fed out by the rollers 1.2, are immediately transferred to the sponge body 6 of the pair of belts 5.7, Therefore, even if there are entangled leaves or entangled roots between the separated seedlings 41 and the group of aligned seedlings 40, the seedlings are separated far enough to separate them. The seedling rows 41a, 41a, etc. to be separated are fed out while maintaining their posture, ensuring separation.
41b, 41c, . . . , the aligned seedling group 40 is sequentially separated into individual seedlings 41, and the separated seedlings 41 are taken out one by one from the belts 5 and 7. After all the separation of the front row of the aligned seedling group 40 is completed, the lateral movement mechanism 2
0 reaches the moving end, the vertical movement mechanism 30 moves the aligned seedling group 40 vertically by one row of seedlings, and at the same time, the roller 1 and the belt 5 and the roller 2 and the belt 7 move in and out, and the first Switching the roles of the rotating body and the second rotating body, the lateral movement mechanism 20 moves the rollers 1 and 2 in the opposite direction.
etc., and the separation of the next column is started. In the above embodiment, the seedling growing container 42 made of a paper cylinder was used as the aligned seedling group 40, but even if the seedling growing medium itself is made of inorganic fibers or polymer compounds forming the seedling growing container, individual seedlings 41 may be It is sufficient if they are connected in an orderly manner so that they can be separated. Further, although the rotary body is shown as having two rollers 1 and 2, the rotary body may be one, or a large number may be provided and separated from a plurality of locations. In addition, although the sponge roller 1.2 is used as the rotating body, one or both sides may be belt-shaped. If both sides are belt-shaped, the first rotating body and the second
Even if there are entangled leaves or entangled roots between the separated seedlings 41 and the group of aligned seedlings 40, it is possible to feed them far enough to separate the separated seedlings 41 and the arranged seedling group 40. Although a roller made of a rigid body such as synthetic resin with many projections or an elastic body such as rubber may be used.Also, if the second rotating body is at the same peripheral speed as the first rotating body Although an example in which the second rotating body rotates in the opposite direction is shown, it is sufficient that the second rotating body rotates in the opposite direction to the first rotating body, and the second rotating body may rotate at a different circumferential speed. At the moving end of 20, the first rotating body and the second
Although an example has been shown in which the rotating body is moved in and out to switch its role and separate continuously, it is also possible to provide a separating device dedicated to each reciprocation and switch it at the moving end of the lateral movement mechanism 20, It is also possible to prepare a plurality of aligned seedling groups 40 and replace them one after another to continuously separate them. In addition, although an example was shown in which the aligned seedling group 40 is intermittently fed by the vertical moving mechanism 3D at the moving end of the horizontal moving mechanism 20, the aligned seedling group 4D is continuously fed and the rotating bodies 1 and 2 are moved correspondingly. Alternatively, the arranged seedling group 40 may be fixed and the rotating body 1.
2 may be moved in correspondence with the seedling rows to be separated. In addition, although an example has been shown in which the aligned seedling group 40 is separated from the vertical state by the rotating bodies 1 and 2 moving laterally, the aligned seedling group 40 may also be in an oblique or inverted state, and the rotating bodies 1 and 2 may be moved. The direction may be in the direction of the row of seedlings to be separated, and is not limited to the horizontal direction; for example, the separation may be performed by moving in the vertical direction. In addition, an example is shown in which the seedlings 41 that are fed out while being sandwiched between the rotating body 1.2 are fed out while being sandwiched between the pair of belts 5 and 7. 41 may be dropped directly into a gutter or the like and planted, or may be placed upside down, placed on a belt, conveyed and arranged, and then planted.

【Effect of the invention】

According to the invention of claim 1, since the rotating body rotates in the same plane as the surface of the group of aligned seedlings and separates the group of aligned seedlings, the seedlings to be separated are separated from the group of aligned seedlings by the rotating body. Since a force is applied in the same plane as the plane of the group, the seedlings to be separated will try to rotate within that plane, and the connections between the seedling-raising containers can be peeled off and separated one by one from the ends without any force, and the seedling-raising containers can be separated. can be reliably separated without damaging it. In addition, since the rotating body moves in the direction of the seedling rows to be separated and separates the group of aligned seedlings into individual seedlings, the separated seedlings are taken out one by one and transferred to the main field in rows as a transplanter. It is also easy to plant the seedlings in a row or to stack them in rows as a seedling processing device. According to the invention of claim 2, the first rotating body is provided which rotates in contact with the side surface of the seedlings to be separated on the front side of the seedling row to be separated in the group of aligned seedlings, and the first rotating body is separated. The side that touches the side of the seedlings is rotated in the opposite direction to the moving direction of the first rotating body at a speed faster than that (since the seedlings are separated, the seedlings are separated in the opposite direction to the rotating direction of the first rotating body). When the seedling tries to rotate, the seedling to be separated is first separated from one end of the connecting part of the next seedling, so it is more difficult (separation can be ensured).
The second rotating body 2 was directed toward the side of the seedlings to be separated that was in contact with the separated seedlings, and the second rotating body was rotated in the opposite direction to the first rotating body, so that the seedlings were not separated. Even if the seedlings being separated are not separated by the first rotating body, the second rotating body subsequently contacts the separated seedlings and tries to rotate in the opposite direction to the first rotating body, Since it is peeled off from the connecting portion on the opposite side from the first rotating body, it can be separated easily and more reliably. In addition, since the separated seedlings are fed out while being sandwiched between the first rotating body and the second rotating body, the separated seedlings are forcibly separated from the group of aligned seedlings. Even if there are entangled leaves or entangled roots between the group of aligned seedlings, the seedlings are fed out far enough to separate them while maintaining a separated posture, allowing for more reliable separation.
