Detailed Description of the Invention [Industrial applications]

The present invention, in transplant cultivation of agricultural crops, a transplanting machine using seedlings raised in a seedling raising container such as a paper tube seedling raising container which is arranged in a plurality of rows in a separably orderly separable manner into individual seedlings, or a seedling treating device, The present invention relates to a separating device for sequentially separating individual seedlings from a group of aligned seedlings by a rotating body.

[Prior art]

A separating device for sequentially separating individual seedlings from a group of aligned seedlings such as paper tube seedlings by a rotating body is, as shown in JP-B-50-21923, a plurality of paragraphs provided corresponding to each seedling row. It has been proposed to separate and drop by a payout body by a rotating disk body having a. Further, Japanese Patent Publication No. Sho 63-50962 proposes a separating device using a plurality of rotating rolls that press against the moving front surface of the separated seedlings of the moving aligned seedling group.

[Problems to be Solved by the Invention]

In the conventional rotating disc having the paragraphs of the prior art, an attempt is made to separate from the vertical direction with respect to the plane of the arrangement direction of the seedlings of the aligned seedling group, and the paper tube raising container has upper and lower openings. Since the paper that forms the paper tube nursery container rots and its strength decreases during the seedling raising period, its connection strength is maintained. The paper tears and causes a separation error,
The left-over seedlings may be obstacles to the next separation and may cause separation errors one after another. Further, in the case of using the plurality of rotating rolls, the separated seedlings are laid down as they are, so that the heights and directions of the seedlings are not uniform and it is inefficient because it requires manpower to align the seedlings. Moreover, since the seedlings are not separated one after another and a large number of seedlings are separated at one time in various directions, this device cannot be used for a transplanter. The present invention solves the above-mentioned problems, surely separates individual seedlings one by one, and a separating device that is fed out as an aligned seedling row even after the separation enables a highly efficient and highly efficient transplanter or seedling treatment device. The purpose is to dramatically expand transplant cultivation.

An embodiment of the present invention will be described below with reference to the drawings. As a seedling raising container 42 that is arranged in a plurality of rows in a separable and orderly manner and connected to individual seedlings 41, a paper tube raising seedling container 42 is shown. This paper tube seedling raising container 42 is a hexagonal column-shaped paper tube with open top and bottom that is tied together with a water-soluble glue. The seedling group 40 is formed, and the water-soluble glue gradually dissolves and disappears due to irrigation, and the paper cylinders gradually bond to each other due to the progress of decay, and maintain an appropriate connection strength during transplantation. However, the paper-lined seedling group 40 with this paper tube rots the paper during the seedling raising period, the strength of the paper tube is reduced and it is easy to tear, and the mutual connection of the paper tubes is too strong, so that they cannot be easily separated. Sometimes you want to. Next, a separation device for separating the aligned seedling group 40 into individual seedlings 41 will be described. In FIG. 1, reference numeral 1 is a rotating body or a sponge body roller as a first rotating body, and 2 is a sponge body roller as a rotating body or a second rotating body.

The roller 2 is rotated in the direction opposite to that of the roller 1 so that the roller 2 faces the side surface on the side, and is brought into close contact with the side surface of the seedling row subsequent to the separated seedling 41a. That is, in FIG. 1, the roller 2 is rotating to the right while moving to the right, and is provided to the left of the separated seedling 41a. The distance between the shafts 3 and 4 of the rollers 1 and 2 and the diameter of the rollers 1 and 2 must be appropriately determined according to the size of the seedling 41 of the aligned seedling group 40, but the shafts 3 and 4 are different from those of the rollers 1 and 2. Closest part is seedling 41
The diameter of the seedling 41 is set to be narrower than the diameter of the seedling 41 so that the separated seedling 41 can be sandwiched between the roller 1 and the roller 2 and fed out. And in this embodiment, the diameter of the seedling 41 is about 2 cm.
The diameters of the rollers 1 and 2 are about twice that, and the distance between the axes 3 and 4 of the rollers 1 and 2 is about 2.5 times that. Further, spur gears (not shown) having the same number of teeth are fitted and meshed with the shafts 3 and 4 of the rollers 1 and 2, so that the rollers 1 and 2 rotate in opposite directions at the same peripheral speed. Shafts 9 and 10 are installed parallel to the shafts 3 and 4 at the same intervals as the shafts 3 and 4, and pulleys 11 and 12 are fitted into the shafts 9 and 10, respectively.

It is rotated by 1,12, and the spur gears (not shown) having the same number of teeth are fitted and meshed with the shafts 9,10,
The belts 5 and 7 rotate in opposite directions at the same peripheral speed, and the peripheral speeds thereof rotate at a speed slightly higher than the peripheral speed of the rollers 1 and 2. Further, the shaft 3 and the shaft 9 are integrated, the shaft 4 and the shaft 10 are integrated,
In addition, the roller 1 and the belt 5 and the roller 2 and the belt 7 are alternately arranged so that the distance between the shaft 3 and the shaft 4 and the distance between the shaft 9 and the shaft 10 do not change, and the conveying direction of the seedling 41 of the pair of belts 5 and 7 is conveyed. That is, the seedling row of the vertically aligned seedling group 40 is moved in and out by a predetermined distance that is slightly less than the pitch of one row of seedlings. On the left and right sides of the front ends of the rollers 1 and 2, seedling regulators 13 and 14 that regulate the position of the aligned seedling group 40 in the frontal direction are provided at substantially the same height as the pair of belts 5 and 7, and the rollers 1 and 2 come and go So that you can go in and out at the same time. The shafts 3 and 4 of the rollers 1 and 2, the shafts 9 and 10, and the seedling regulators 13 and 14 are provided on the lateral movement mechanism frame 21 that is a substantially rectangular shape in plan view as the lateral movement mechanism 20, and the aligned seedling group 40 Reciprocate laterally a distance slightly wider than the width. Below the lateral movement mechanism frame 21, two shafts 22 and 23 that are long in the movement direction and have the same height are provided, and the shafts 22 and 23 are fitted into the lateral movement mechanism frame 21 and move along it. . Although not shown, the shaft 23 is engraved with a cylindrical cam in which a forward groove and a backward groove, which are known in rice transplanters and the like, are formed in an endless cross shape, and mesh with a protrusion (not shown) provided in the lateral movement mechanism frame 21. The rotation of the shaft 23 causes the lateral movement mechanism frame 21 to continuously reciprocate in the lateral direction, and the movement speed thereof is slower than the outer peripheral speed of the rollers 1 and 2, and in the embodiment, about the same. 1/3. In front of the rollers 1 and 2, a vertical movement mechanism 30 for moving the aligned seedling group 40 in the vertical direction of the pair of belts 5 and 7 in the conveying direction of the seedlings 41.
To provide. The vertical movement mechanism 30 is provided with a vertical movement mechanism frame 31 having a substantially rectangular shape in a plan view, and a pair of seedling guides that are long in the vertical direction at intervals slightly wider than the width of the aligned seedling group 40 on the left and right above the vertical movement mechanism frame 31. 32 is provided. Then, on the vertical movement mechanism 30, aligned seedlings 40
And the left and right moving ends of the horizontal moving mechanism 20 are intermittently moved in the vertical direction. The vertical movement mechanism 30 includes a horizontal movement mechanism 20 in a vertical movement mechanism frame 31.
A pulley 34 is provided on the side farther from the rollers 1 and 2 at the same height in the moving direction, and a pulley 35 is also provided on the side closer to the rollers 1 and 2. A belt 33 having a width slightly narrower than the width of the lateral movement mechanism frame 21 is stretched between the two pulleys 34 and 35.
Then, the pulley 34 is arranged at the moving end of the lateral movement mechanism 20 so that the seedlings are aligned.
Rotate so that only one row of 40 seedlings is intermittently transferred in the direction of rollers 1 and 2. Next, the operation will be described. The lateral movement mechanism 20 of the seedling separation device is a predetermined moving end,
Place the aligned seedling group 40 on the belt 33 as the vertical movement mechanism 30,
The front end of the aligned seedling group 40 is fed to a position where it comes into contact with the seedling regulating body 13 on the roller 1 side as the first rotating body. At this time, the front end of the roller 1 as the first rotating body is located in contact with the front end of the front row of the aligned seedling group 40, and the front end of the roller 2 as the second rotating body is at the second row of the aligned seedling group 40. The position is almost the same as the front end. When the shafts 3, 4 and the shafts 9, 10 and the shaft 23 are rotated by an appropriate means, the lateral movement mechanism frame 21 moves laterally and the rollers 1, 2
The belts 5 and 7 and the seedling regulation bodies 13 and 14 move integrally, and the rollers 1 and 2 and the belts 5 and 7 rotate. As a result, the seedling rows 41a, 41 separated from the aligned seedling group 40 are separated.
The front end of the roller 1 as the first rotating body contacts and rotates on the side surface of the seedling 41a separated on the front side of b, 41c, .... At this time, the direction of rotation of the roller 1 is such that the side in contact with the side surface of the seedling 41a separated from the roller 1 rotates in the direction opposite to the direction of movement of the roller 1, and the peripheral speed thereof is faster than the speed of movement of the roller 1. Therefore, the seedling 41a to be separated is subjected to a force in the same in-plane direction as the surface of the aligned seedling group 40 from the roller 1, the seedling 41a to be separated tries to rotate in the surface, and Seedling container 42 with seedling 41b and subsequent seedling row
The mutual connections are peeled off from their ends without difficulty, and the separated seedlings 41 are sandwiched between the following row of seedlings and the roller 1, rolled and separated. Also, since the separated seedling 41a is rolled in the direction opposite to the rotation direction of the roller 1, the seedling 41b next to the separated seedling is separated because it is connected to the next seedling 41c and the subsequent seedling row. Since it is impossible to rotate in the same direction as the seedling 41a to be separated, first peeled from the front side end of the connecting portion of the next seedling 41b of the separated seedling, the seedling 41b next to the separated seedling is separated. The seedling 41a is not pulled out while being connected to the seedling 41a and is reliably separated. The seedling 41 separated and fed by the roller 1 is provided so as to face the side surface of the seedling 41a, which is subsequently separated from the roller 1 by approaching the aligned seedling group 40, in contact with the already separated seedling 41. Since the roller 2 as a second rotating body comes into contact with the roller 2 and the roller 2 is rotating in the opposite direction to the roller 1, the separated seedling 41 is sandwiched between the rollers 1 and 2 and fed out. It is forcibly separated from the aligned seedling group 40. Further, even if the separated seedling 41a is weakly contacted with the roller 1 and is not separated, the seedling 41a subsequently contacts the roller 2 and is rolled by the roller 2 in the opposite direction to the roller 1 and separated. . Then, the seedlings 4 fed out by being sandwiched by the rollers 1 and 2
1 is the sponge body 6,8 of the pair of belts 5,7 immediately.
It is sandwiched by and is extended further. For this reason, even if there is a leaf entanglement or root entanglement between the separated seedling 41 and the aligned seedling group 40, it is fed out while keeping the separated posture sufficiently far enough to separate it, and the separation is ensured. Become. The rollers 1 and 2 are separated from the seedling rows 41a, 41b and 41.
Since they are moving in the c, ... direction, 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 the separation of the front row of the aligned seedling group 40 is completed, the lateral movement mechanism 20
When the moving end reaches the moving end, the vertically moving mechanism 30 vertically moves the aligned seedling group 40 by one row, and at the same time, the roller 1 and the belt 5 and the roller 2 and the belt 7 move in and out to make the first rotation. The roles of the body and the second rotating body are switched, and the lateral movement mechanism 20 laterally moves the rollers 1, 2 and the like in the opposite direction to start separation of the next row. In the above examples, the seedling container 42 with a paper tube is shown as the aligned seedling group 40, but even if the seedling culture medium itself is the inorganic fiber or polymer compound forming the seedling container, each seedling 41 is It is sufficient if they are separably and orderly connected. Also, two rollers as the rotating body of the invention of claim 1.
Although shown by 1 and 2, one of the roller 1 and the roller 2 may be used as the rotating body and a fixed body may be provided on one side, or a plurality of rotating bodies may be provided and separated from a plurality of locations. Also, although the sponge rollers 1 and 2 are shown as the rotating body, one or both sides may be formed into a belt shape, and when both sides are formed into a belt shape, the first rotating body and the second rotating body are formed. Even if there is a leaf entanglement or a root entanglement between the separated seedling 41 and the aligned seedling group 40, only the separated seedling 41 and the aligned seedling group 40 can be extended far enough. Although a sponge body is shown because the paper tube seedling is illustrated, a rigid roller made of synthetic resin or the like with a large number of protrusions or an elastic body such as rubber may be used. Further, although the example in which the second rotating body rotates in the opposite direction at the same peripheral speed as the first rotating body has been shown, it is sufficient that the second rotating body rotates in the opposite direction to the first rotating body. Alternatively, they may be rotated at different peripheral speeds. Further, at the moving end of the lateral movement mechanism 20, the first rotating body and the second rotating body
Although an example was shown in which the rotating body is moved in and out and its role is switched to perform continuous separation, it is also possible to provide a dedicated separating device for each reciprocating and switch it at the moving end of the lateral moving mechanism 20. It is also possible to prepare a plurality of aligned seedling groups 40 and replace them one by one to separate them continuously. Further, the example of intermittently feeding the aligned seedling group 40 by the vertical movement mechanism 30 at the moving end of the lateral movement mechanism 20 is shown, but the aligned seedling group 40 is continuously fed to move the rotating bodies 1 and 2 in correspondence therewith. Alternatively, the aligned seedling group 40 may be fixed and the rotating bodies 1 and 2 may be moved in correspondence with the row of seedlings to be separated. Further, the example of separating the aligned seedling group 40 from the standing state by the rotating bodies 1 and 2 moving in the lateral direction is shown, but the aligned seedling group 40 may be in an oblique state or an inverted state, and the moving of the rotating bodies 1 and 2 The direction is not limited to the horizontal direction as long as it is the seedling row direction to be separated, and for example, it may be moved vertically to be separated. Further, an example has been shown in which the seedling 41 fed between the rotating bodies 1 and 2 is fed between the pair of belts 5 and 7, but the seedlings fed between the rotating bodies 1 and 2 are shown. The 41 may be dropped directly into a gutter or the like for planting, or it may be inverted and then placed on a belt to be conveyed and aligned before being planted.

Since the seedlings to be separated tend to rotate in the plane and the connection between the seedling-growing containers can be peeled off from their ends in sequence without difficulty, the seedling-growing container can be reliably separated without damage. In addition, a lateral movement mechanism that moves in the separated seedling row direction is provided, a rotary body that separates the seedlings is provided in the lateral movement mechanism, and the rotary body that separates the seedlings moves in the separated seedling row direction and is separated. Since the seedlings are taken out one by one, it is easy to plant the seedlings in a row in the main field as a transplanter or to align and deposit them as a seedling treatment device. According to the invention of claim 2, a first rotating body that rotates in contact with a side surface of the separated seedling is provided on the front side of the separated seedling row of the aligned seedling group, and the first rotating body is separated. The side contacting the side of the seedling should rotate in the direction opposite to the moving direction of the first rotating body and faster than its moving speed, and the separated seedling should try to rotate in the direction opposite to the rotating direction of the first rotating body. Therefore, the seedling to be separated is peeled off from one end of the connecting portion of the seedling next to the seedling to be separated more reasonably and surely. Further, a second rotating body is provided behind the first rotating body in the moving direction, the second rotating body is rotated in the opposite direction to the first rotating body, and the first rotating body and the second rotating body are rotated. The body is integrally moved in the seedling row direction of the seedlings to be separated next, and the separated seedlings are sandwiched between the first rotating body and the second rotating body to be fed out,
Since the separated seedlings are forcibly separated from the aligned seedling group, even if there is a leaf entanglement or root entanglement between the separated seedling and the aligned seedling group, the posture that is separated sufficiently far enough to separate it It is fed out while maintaining the temperature, and more reliable separation is possible.
