[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is designed to separate individual seedlings into individual seedlings in a transplanter that uses aligned seedlings such as paper tube seedlings in a paper tube growing seedling container that is orderly and separably connected to each seedling in transplant cultivation of agricultural crops. Separation device.

[0002]

[Prior art]

 The inventors of the present invention previously provided, as Japanese Patent Application No. 3-285632, a first rotating body that comes into contact with a moving side surface of a seedling from which an aligned seedling is separated, and a surface of the first rotating body that comes into contact with the aligned seedling is separated. Rotate forward in the moving direction of the separated seedlings, and make the speed of the surface of the first rotating body in contact with the aligned seedlings faster than the moving speed of the seedlings, and make a second rotation forward in the moving direction of the separated seedlings. A body is provided so that the second rotating body rotates in the direction opposite to that of the first rotating body, and the separated seedlings not separated by the first rotating body have the moving front face of the second rotating body. We proposed a device for separating aligned seedlings so that they can be separated by contact.

In this apparatus for separating aligned seedlings, the second rotating body is positioned closer to the aligned seedlings than the first rotating body, and the first rotating body and the second rotating body are separated from each other at the moving end of the lateral movement mechanism. I was moving back and forth for a certain distance.

[0004]

[Problems to be solved by the device]

 In the above conventional technique, the second rotating body is located closer to the aligned seedlings than the first rotating body. Therefore, if the soil in the paper container of the seedling-growing container is not sufficiently filled, the paper container will be crushed. The second rotating body may come into contact with the seedling row next to the seedling row to be separated, and may separate up to the next seedling row or break the paper cylinder of the next seedling row.

Further, since the first rotary body and the second rotary body are moved back and forth by a predetermined distance at the moving end of the lateral movement mechanism, a mechanism for moving the first rotary body and the second rotary body back and forth is required. Therefore, the transmission of rotational power to the first rotating body and the second rotating body is complicated.

[0006] The present invention solves the above problems and ensures high-performance and high-efficiency aligned seedlings that are reliably separated into individual seedlings and are continuously separated into individual seedlings by a separation device with a simple mechanism. The purpose of the present invention is to provide a separating device for the purpose of dramatically expanding transplant cultivation.

[0007]

[Means for Solving the Problems]

 The apparatus for separating aligned seedlings according to the present invention is an apparatus for moving the aligned seedlings P that are orderly and separably connected to the individual seedlings Pb and supplying the separated seedlings Pb to separate them into individual seedlings Pb. The first rotating body 31 elastically deformed and in contact with the moving side surface of the seedling Pa to be formed is provided, and the surface of the first rotating body 31 in contact with the aligned seedling P is normally rotated in the moving direction Mc of the separated seedling Pa, The speed of the surface of the first rotating body 31 in contact with the aligned seedlings P is made faster than the moving speed of the aligned seedlings P, and the distance from the aligned seedlings P is first in the moving direction Mc of the separated seedlings Pa of the aligned seedlings P. The second rotating body 32 is provided at the same position as that of the rotating body 31, and the second rotating body 32 is rotated in the opposite direction to the first rotating body 31 and separated by the first rotating body 31. The seedlings Pa that were not separated were so separated that their moving front surfaces were in contact with the second rotating body 32.

[0008]

[Work]

 In the present invention, since the first rotating body 31 elastically deforms and contacts the moving side surface of the separated seedling, the second rotating body 32 is located at the same distance from the aligned seedling P as the first rotating body 31. Even so, the second rotating body 32 is in the moving direction Mc ahead of the separated seedling Pa.

Further, since the second rotating body 32 is located at the same position as the first rotating body 31 from the aligned seedlings P, even if the moving direction of the aligned seedlings P is changed, There is no need to change the position of the second rotating body 32.

This paper tube nursery container is a hexagonal column-shaped paper tube that is open at the top and bottom when unfolded, and is orderly bonded with water-soluble glue. When this paper cylinder is filled with soil and sown, and the seedlings are raised, the seedlings grow and become the aligned seedlings P of the paper cylinder seedlings, and an appropriate connection strength is maintained at the time of transplantation. However, the aligned seedlings P in this paper tube nursery container will be crushed when the seedlings are separated into individual seedlings if the soil is not sufficiently packed, or the paper will rot during the seedling raising period.

As a result, the lateral movement mechanism frame 12 continuously reciprocates in the direction of the rail 11.

The lateral movement mechanism frame 12 of the lateral movement mechanism 10 is provided with a vertical movement mechanism 20 that moves in a direction orthogonal to the movement direction Mc of the lateral movement mechanism 10. Then, the aligned seedlings P are placed on the belt 25 of the vertical movement mechanism 20 and intermittently in the direction orthogonal to the moving direction Mc of the horizontal movement mechanism 10 (downward in FIG. 1) at the moving end of the horizontal movement mechanism 10. Move to.

The vertical moving mechanism 20 is provided with pulleys 22 and 24 that are long and parallel to each other in the moving direction Mc of the horizontal moving mechanism 10 in the horizontal moving mechanism frame 12, and a belt 25 is provided between the pulleys 22 and 24. Cross over. Then, the lateral movement mechanism frame 12 moves laterally to the pulley 22 so that the rotation of the shaft 16 is conducted only at the movement end thereof, and the row of the aligned seedlings P of the aligned seedlings P is moved at the movement end of the lateral movement mechanism 10. The pulley 22 is rotated so as to move the belt 25 slightly more than one row.

A regulation body frame 2 is provided outside the machine frame 1 in parallel with the rail 11 in the moving direction of the vertical movement mechanism 20, and a regulation body shaft 3 is provided vertically above the regulation body frame 2 to A pair of freely rotating seedling restraint belts 5 are hung on the upper end.

The seedling regulation belts 5 are provided on the left and right sides of the lateral movement mechanism 10 for a long time in the moving direction Mc, and the surface on the side of the aligned seedlings P is located at substantially the same position as the conveyance end of the belt 25. A space is provided between the inner ends of the gutter 5 to accommodate the pair of separating rotary bodies 31 and 32 for separating and feeding the aligned seedlings P. Two belt drive pins are provided on the upper and lower sides in the direction of the seedling regulation belt 5 from the ends of the pair of lateral movement mechanism frames 12 on the seedling regulation belt 5 side, and the belt drive pins are provided on the surface of the seedling regulation belt 5 on the side of the aligned seedlings P. When the lateral movement mechanism 10 reciprocates through the hole, the surface of the seedling regulating belt 5 on the side of the aligned seedlings P reciprocates in the same direction.

A separating section frame 30 is provided above the machine frame 1 and between the inner sides of the pair of seedling regulating belts 5 at the center in the moving direction of the vertical moving mechanism 20.

A pair of shafts 33, 34 is provided below the separation part frame 30 and outside the separation part frame 30. The pair of shafts 33, 34 are parallel to the moving direction Mc of the lateral movement mechanism 10 and The positions in the moving direction are the same, gears with the same number of teeth mesh with the pair of shafts 33, 34, and they rotate in opposite directions at the same speed.

The pair of shafts 33, 34 outside the separating portion frame 30 are provided with a pair of elastic rollers 31, 32 as a separating rotating body fitted therein. Since the rollers 31 and 32 are fitted in the pair of shafts 33 and 34 having the same position in the moving direction of the vertical moving mechanism 20, the rollers 31 and 32 are provided at the same distance from the aligned seedlings P. The rollers 31 and 32 are cylindrical sponge bodies, and the rollers 31 and 32 are positioned so as to contact with the upper and lower sides of the side surface of the aligned seedling P placed on the belt 25, and the pair of rollers 31 and 32 are individual seedlings. The spacing should be narrower than the paper tube diameter of Pa.

In addition, the pair of shafts 33, 34 rotate at the same speed in the opposite directions, so that the pair of rollers 31, 32 rotate at the same speed in the direction in which the surfaces facing each other move away from the aligned seedling P, The peripheral speed is about three times as fast as the moving speed of the lateral moving mechanism 10.

Further, in FIG. 4, the side where the aligned seedlings P laterally move by the lateral movement mechanism 10 and approaches is the first roller 31 as the first rotating body, and the side that moves away is the second rotation. The second roller 32 as a body is used.

The first roller 31 is positioned so as to elastically deform and contact the moving side surface of the separated seedling Pa of the aligned seedling P, and the surface of the first roller 31 contacting the aligned seedling P moves of the separated seedling Pa. It rotates normally in the direction Mc, and the speed of the surface of the first roller 31 in contact with the aligned seedling P is faster than the moving speed of the aligned seedling P.

The second roller 32 is located at the same distance from the first roller 31 as the aligned seedling P. Since the second roller 32 is not in contact with the aligned seedling P, it is not deformed and is separated. It is located in front of the moving direction Mc of the seedling Pa and is rotating in the opposite direction to the first roller 31, and when the separated seedling Pa that was not separated by the first roller 31 moves as it is, its moving front surface becomes Contact the second roller 32.

A pair of flat belts 38 are provided outward from the opposite sides of the rollers 31, 32 to the aligned seedlings P by a shaft provided below the separating part frame 30. The flat belt 38 receives the individual seedlings Pb separated and fed from the rollers 31 and 32, sandwiches and conveys the seedlings Pb in the middle part of the paper cylinder, and feeds them to the opposite side of the aligned seedlings P.

A pair of flat belts 39 is provided in a direction perpendicular to the end of conveyance of the flat belts 38 by a shaft provided below the separating frame 30. The flat belt 39 receives the individual seedlings Pb delivered from the end of the transport of the flat belt 38, and sandwiches the upper part of the paper tube to convey and deliver it.

Next, the operation will be described.

The lateral movement mechanism frame 12 of the lateral movement mechanism 10 has its predetermined moving end, and the aligned seedlings P are placed on the belt 25 as the vertical movement mechanism 20 on the lateral movement mechanism 10, and the front end of the aligned seedlings P is placed. The separated rows of seedlings Pa are brought into contact with the seedling regulation belt 5 and elastically deform the first roller 31 to the position where they come into contact.

When the shaft 16 or the like is rotated by an appropriate means and the lateral movement mechanism frame 12 is laterally moved, the aligned seedling P is laterally moved, and the rollers 31, 32, the flat belts 38, 39, etc. are rotated. .

By the lateral movement of the lateral movement mechanism frame 12, as shown in FIG. 4, the row of the separated seedlings Pa in the front row of the aligned seedlings P moves in the illustrated movement direction Mc, and the first roller sequentially. Deform 31 and touch the front end.

At this time, the surface of the first roller 31 that is in contact with the side surface of the separated seedling Pa of the aligned seedlings P is normally rotated in the moving direction Mc of the separated seedling Pa and is rotating to the right in the figure, The separated seedlings Pa are sandwiched between the subsequent row of seedlings and the first roller 31 and rotated, so that the rotational force is reliably transmitted, and the separated seedlings Pa are rotated leftward. Therefore, the separated seedling Pa is peeled off from the connection portion of the seedling Pa next to the separated seedling Pa, and then separated from the connection portion with the next succeeding row of seedlings to be separated into individual seedlings Pb without difficulty. .

Further, since the speed of the surface of the first roller 31 in contact with the separated seedlings Pa is faster than the moving speed of the aligned seedlings P, the separated seedlings Pa and the next succeeding seedling row and It is sandwiched between the first roller 31 and the roller 31 and is rotated at a speed higher than the moving speed of the aligned seedlings P, so that the separated seedling Pa is separated from the next seedling Pa and is reliably separated. It

The separated seedling Pb is also in contact with the second roller 32 provided in front of the movement of the separated seedling Pa, and the second roller 32 rotates in the opposite direction to the first roller 31. Therefore, it is sandwiched between the pair of rollers 31 and 32 and is fed to the opposite side of the aligned seedlings P while standing.

At this time, since the first roller 31 is elastically deformed to come into contact with the moving side surface of the separated seedling, the second roller 32 has the same distance from the aligned seedling P as the first roller 31. Even in this position, the second roller 32 is located in front of the moving direction Mc of the separated seedling Pa, and the distance between the separated seedling Pa and the next seedling row following the separated seedling Pa is sufficiently large.

Even if the separated seedling Pa is not separated by the first roller 31, if the separated seedling Pa moves as it is, the separated seedling Pa moves to the second roller 32 in front of the movement of the separated seedling Pa. The moving front surfaces of the first roller 31 and the first roller 31 are rotated in the opposite direction to the first roller 31, separated, and then fed out. Therefore, it is possible to prevent the occurrence of a separation error and ensure the separation.

Then, the seedling Pb sandwiched between the pair of rollers 31 and 32 and delivered is immediately sandwiched between the flat belts 38 and 39 and delivered further away, and is transferred to the main field by an appropriate transplanting device. Ported.

Further, since the first roller 31 and the second roller 32 as the separating rotating body can be continuously contacted with the aligned seedlings P to be separated, the side surface of the row of the seedlings Pa from which the aligned seedlings P are separated rotates. By sequentially contacting the first roller 31 with the second roller 32, the individual seedlings Pb are continuously separated and delivered.

When all the separated seedling rows in the front row of the aligned seedlings P are finished and the lateral movement mechanism frame 12 reaches the moving end, the aligned seedlings P are vertically moved by the belt 25 by one row. Then, the lateral movement mechanism frame 12 subsequently laterally moves the aligned seedlings P in the opposite direction, and the separation of the next row is started.

At this time, the second roller 32 is arranged at the same distance from the aligned seedling P as the first roller 31, and even if the moving direction of the aligned seedling P is changed, Since it is not necessary to change the position of the roller 32, there is no need for a mechanism for moving the first roller 31 and the second roller 32 forward and backward, and transmission of rotational power is simple. Then, as shown in FIG. 5, the roller 32 serves as the first rotating body and the roller 31 serves as the second rotating body, and the roles thereof are alternately separated.

Further, the belt 25 also intermittently moves the aligned seedlings P at the moving end on the opposite side of the lateral movement mechanism frame 12, and the seedlings Pa are continuously separated.

In the above examples, the paper tube seedlings in the paper tube seedling raising container are shown as the aligned seedlings P, but the soil itself is hardened in a predetermined shape, or the inorganic fiber or the seedling growing medium itself is connected in an orderly manner. Even a polymer compound may be used as long as it is separably and orderly linked to each seedling Pa.

Further, although the rollers 31 and 32 of the cylindrical sponge body are shown as the first rotating body and the second rotating body, either or both of the first rotating body and the second rotating body are shown. The other side may be belt-shaped.

Further, as the first rotating body and the second rotating body, the pair of rollers 31 and 32 rotate in opposite directions at the same speed, but the first rotating body and the second rotating body are shown. There may be a speed difference in the rotation of the body.

[0046]

[Effect of device]

 According to the present invention, the first rotating body elastically deforms and contacts the moving side surface of the separated seedling, and the second rotating body is located at the same distance from the aligned rotating seedling as the first rotating body. , The second rotating body is sufficiently separated from the next seedling row following the separated seedling, and even if the paper cylinder of the seedling raising container is not sufficiently filled with the soil, the paper cylinder is crushed. The second rotating body does not come into contact with the next row of seedlings to be separated, separate the next row of seedlings, or break the paper cylinder of the next row of seedlings.

In addition, the second rotating body is located at the same position as the first rotating body from the aligned seedlings, and even if the moving direction of the aligned seedlings is changed, the second rotating body is separated from the first rotating body. Since there is no need to change the position, there is no need for a mechanism for advancing and retracting the first rotating body and the second rotating body, and the transmission of the rotational power becomes simple.
