Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a potato seeding machine that cuts whole seeds and sows them in the main field, or a stationary potato seed cutting device.

In the case of this type of conventionally provided products, since the seeds are cut in the longitudinal direction during cutting, it requires labor such as manually arranging the seeds, and in the case of a method in which the cutting blade is rotated, Seeds had to be supplied individually to the cutting position, which naturally limited efficiency.

The present invention aims to fully solve such problems, and the first invention is suitable for means such as a stationary potato seed cutting device in which cut seeds are dropped together into a container, and the second invention is It is suitable for means such as a potato seeding machine, in which cut seeds are separated from each other and dropped at different locations. Whole potato seeds have an oval shape, and must be cut in the longitudinal direction.A pair of rollers made of an elastic material with the same elasticity is rotated inwards, and a pair of rollers is cut from above. When the potato seeds are fed for a short period of time, they are smoothly bitten into the longitudinal direction, and a cutting blade is provided at the center of the pair of rollers for a short period of time, and the pair of rollers are energized and displaced by the same distance. If they are arranged freely, the potato seeds will be cut into nearly half the size, and if the transfer conveyors corresponding to each of the cut potato seeds are arranged in a V-shape, they will fall to different locations. The present invention was developed by focusing on the fact that this can be done.

The present invention will be described in detail below with reference to the drawings.The reversing roller 4, screw conveyor 5,
A guide roller 7 is provided, and the screw conveyor 5 and the guide roller 7 are mounted parallel to each other in substantially the same plane, and the reversing roller 4 is connected to the screw conveyor 5.
The shaft is mounted parallel to the top of the A seed supply gutter 1 is provided above the starting end of the screw conveyor 5.
A swingable regulating plate 2 is provided inside the device to smooth the flow of seeds, and this is swinged by a lever 3 to keep the flow of seeds supplied to the screw conveyor 5 constant. A seed cutting device is provided below the terminal end of the screw conveyor 5, which comprises a holding roller 11 made of an elastic roller having the same elastic force, and a cutting blade 13 made of a fixed blade body. The holding roller 11 is the shaft 1
2, and is driven to rotate internally by a sprocket and a chain, and the distance between the pair of holding rollers 11 is set to a small distance that prevents the potato seeds from freely passing through, that is, about 20 mm, and the shaft 12 is attached to the arm body. 2
The arms 20, 20' are rotatably supported on the machine frame 10 via a shaft 23, and the shafts 20, 20' of the arms 20, 20' are rotatably supported on the machine frame 10 through a shaft 23.
3. Teeth 22, 22' are provided on the peripheral edges near the teeth 22, 22', which mesh with each other so that the arms 20, 20' can be displaced by the same angle in opposite directions, thereby making the displacement distance of the pair of holding rollers 11 from the cutting blade 13 the same. . arm body 2
Engagement pieces 21, 21' are provided at the intermediate part of 0, 20',
A tension spring 25 is engaged between the engagement pieces 21 and 21' to elastically bias the pair of holding rollers 11 toward the inner cutting blade 13. Shaft 12 of holding roller 11
The shaft 1 is placed at the center between the two shafts at almost the same height as the shaft center of the
A cutting blade 13 is arranged with the cutting edge 31 facing parallel to 2,
The engaging piece 26 provided on the machine frame 10 and the hole 29 provided on the cutting blade 13 are fastened with bolts 27 and nuts 28. A pair of transfer conveyors 19 corresponding to both sides of the cutting blade 13 are provided below the cutting blade 13 in a "V" shape, and are rotatably supported between the machine frames 9 and 10 by shafts 16 and 16'. The distance between the discharge ends of the pair of transfer conveyors 19 is adjustable. The transfer conveyor 19 is synchronized with the winged conveyor 14 and the flat conveyor 15, which are driven to internally rotate with respect to each other, and is configured to collect and transfer the cut seeds.
The winged conveyor 14 is supported by shafts 17, 17' and 18', and the flat conveyor 15 is supported by shafts 16, 16' and 18, and shafts 16, 16', 17, 1
7' are configured to be connected and driven by a sprocket and a chain, respectively. Any elastic material can be used for the holding roller 11, but
Preferably, a rubber sponge with high hardness or natural rubber with low hardness is desirable, and it is more preferable to provide unevenness on the surface to improve the biting. The cutting blade 13 is a hardened blade made of carbon tool steel or the like, but in order to prevent the cut seeds from sticking to the blade surface, it is better that the blade surface is not smooth, and a plurality of holes 30 are formed on the blade surface. It is preferable to reduce the contact area by providing such a structure, or to introduce it into the contact surface to facilitate the separation of the seeds from the cutting blade 13. In addition, the cutting blade 13
If the cutting blade 13 is driven to swing without being fastened to a fixed body, the ability to remove the seeds from the cutting blade 13 is further improved. If the cutting blade 13 is configured to spray or drop a disinfectant, pathogenic bacteria on the seeds will not infect other seeds.

Next, to explain the operation of the present invention, the seeds supplied to the supply gutter 1 are sequentially dropped in appropriate amounts onto the screw conveyor 5 by the regulating plate 2, and are transferred while being rolled by the action of the threaded string 6, and guided. One seed corresponds to the gap divided by the threaded string 6 of the roller 7 and the screw conveyor 5, and one seed can be easily separated.
The seeds are arranged into individual seeds and transported. The seeds discharged from the screw conveyor 5 are
In the invention and the second invention, the holding roller 1
1 is largely displaced relative to the large potato seed, and slightly displaced relative to the small potato seed, and elastically held by the holding roller 11 and pressed against the cutting blade 13 to be cut in half. However, at this time, since the holding roller 11 is configured to be displaced by the same amount on the left and right depending on the size of the seed, the seeds can be cut nearly in half, and the rotation of the holding roller 11 bites into the seeds in the longitudinal direction. The cut surface of the seeds can also be longitudinal. In the second invention, the seeds cut into two by the cutting blade 13 are transferred by the left and right transfer conveyors 19, respectively, and when sown in the main field, the discharge end distance of the transfer conveyor 19 is set to be the same as the furrow. If the conveyance direction of the transfer conveyor 19 is arranged perpendicular to the direction of movement of the machine, it is possible to simultaneously sow two rows with the set of apparatus according to the present invention, and the discharge end distance of the transfer conveyor 19 is made the same as the distance between plants, If the conveyance direction of the transfer conveyor 19 is arranged parallel to the direction of movement of the machine, two seeds can be sown in the same row at once, resulting in a very highly efficient seeding machine.

Since the present invention is configured as described above, in the first invention and the second invention, potato seeds are elastically held on the rollers using the holding roller 11 made of a pair of elastic rollers having the same elastic force. Since the seeds are cut by being pressed against the cutting blade 13 while being bitten and conjugated, it is possible to cut the seeds in the longitudinal direction with extremely high efficiency.In addition, the structure is simple, there are few failures, and the operation is smooth, making it possible to cut potato seeds. It has the effect of being painless. In the second invention, one potato seed is further cut into two seed pieces, which are separated by a pair of transfer conveyors 19 and sown simultaneously in two rows, or simultaneously in the same row between plants. By being able to sow seeds at intervals, it has the effect of providing a very highly efficient seeding machine.
