Description

[Detailed explanation of the invention] When planting 2-year-old and 3-year-old Konniyaku potatoes mechanically, the buds will have grown several times at the time of planting, so the buds will not be damaged. Since the potatoes must be planted so that the sprouts are facing upward, the required number of conveyor plates are planted at equal intervals at right angles to the direction of rotation of the belt, and the Konniyaku potatoes are planted between the conveyor plates. By feeding, the belt rotates and the konnyaku yam is conveyed downward, and the bottom pulley is used to plant the konnyaku yam, which is equipped with a front cover that covers the front of the lower end of the belt where it is folded back. In the attaching machine, the upper end of a flexible elastic plate such as a rubber plate with resilience is supported on the inside of the front cover by the upper part of the front cover,
The lower end of the elastic plate is aligned near the lower end of the front cover, and the middle of the elastic plate is kept above the curved surface of the front cover.Structure of the potato dropping part of the conveying device in the Konnyaku potato planting machine. When the Konniyaku sweet potato falls to the ground, the probability that the sprout will be in an upward position is very high.

To explain the drawings, numeral 1 is a towing metal fitting disposed at the rear of a towing vehicle (not shown) such as a walking tractor, and numeral 2 is a machine frame on which each component of the present invention is mounted. Reference numeral 3 denotes a connecting rod which is fitted inside the towing fitting 1 and fixedly installed so as to be vertically adjustable, and its lower end is fixed to the front end of the machine frame 2. 4 is a pair of wheels arranged on the left and right, and bearings 5 are arranged on the lower left and right sides of the machine frame 2, respectively.
They are respectively fixed to both left and right ends of an axle 6 which is rotatably supported by. Reference numeral 7 denotes a support frame for supporting pulleys (described later), which consists of a pair of left and right sides, each lower end of which is fixed to the middle part of the machine frame 2 and stands parallel to the left and right, and its rising portion a has the same slope on both sides. The upper part is inclined rearward at the corner, and an overhang part b is provided at the upper end of the rising part a, which is bent and extended rearward in left and right parallel directions. Reference numeral 8 denotes a lower pulley that is rotatably supported on the lower part of the support rack 7, and reference numeral 9 designates a lower pulley that is rotatably supported by the lower part of the support rack 7, and 9 is a protrusion b on the upper part of the support rack 7 at a position where its front surface is set back from the front surface of the lower pulley 8.
The front pulley is rotatably supported on the front end of the
0 is a rear pulley rotatably supported by the rear end of the overhang b, and 11 is a belt wound around the pulleys 8, 9, and 10. Reference numeral 12 denotes a large number of conveyor plates installed at equal intervals on the surface of the belt 11, and the conveyor plates 12
Both plate surfaces are perpendicular to the longitudinal direction of the belt 11, and the receiving surface 12' (ie, the surface that faces upward when descending) of the conveying plate 12 embedded in the belt 11 forms a shallow ∨ shape. Due to the above-mentioned relative positions of the lower pulley 8 and the front pulley 9 of the belt 11, the upper part forms a rearward slope. Therefore, as the belt 11 runs around, the surface of the conveying plate 12 that passes between the lower pulley 8 and the front pulley 9 all forms an inclined surface with the implanted side facing lower and the leading edge side facing higher. 13 is a chain wheel fixed to the axle 6, 14 is a chain wheel attached to the lower pulley 8, and 15 is a chain wheel attached to the chain wheel 13 and the chain wheel 14, so that the power generated by the rolling of the wheel 4 is transferred to the lower pulley 8.
It is a transmission chain that transmits power to the Reference numeral 16 denotes a front cover disposed on the front side of the lower pulley 8 so as to cover the belt 11 in close proximity to the belt 11 so as to allow passage of the implanted conveyor plate 12, and is fixed to the machine frame 2. Konniyaku sweet potato A
The input section B for inputting the front cover 1 is provided almost horizontally.
The lower end of 6 is provided between the horizontal line and the vertical line at the center of the lower pulley 8, and is opened so that Konnyaku Potato A can fall to the ground. This prevents the cover from falling off the conveyance plate 12 while being conveyed to the lower end of the cover 16. front cover 16
An elastic plate 17 having a restoring force such as a rubber plate is arranged inside the front cover 16 and fixed to the upper end of the front cover 16 at the upper end of the elastic plate 17. The lower end of the front cover 17 is slightly longer than the lower end of the front cover 16 so that it is received without being fixed, and the middle part is the front cover 1.
6 and the elastic plate 17 to maintain a gap between them. 1
Numeral 8 denotes seed boxes loaded with Konniyaku sweet potatoes A mounted on the left and right sides of the support rack 7, and supported by left and right pillars 19 that stand up with their lower ends fixed to the machine frame 2, respectively. 20 is a groove cutting plate that opens a groove in the soil surface in which the potatoes A are dropped and arranged in close proximity to the front of the lower end of the front covering 16; 21 is a groove cutting plate whose lower end is fixed to the front part of the groove cutting plate 20; This is a mounting rod that is fitted into a support 22 fixed to the front part of the machine frame 2 and fixes the groove plate 20 so as to be vertically adjustable. Arrow E indicates the direction of rotation of the wheel 4. C is the surface of the field. D indicates the groove bottom. S indicates a plurality of strips cut into the lower part of the elastic plate 17.

Next, to explain the operation, when the Konniyaku potato planting machine is connected to the rear part of a tractor or traction machine and moves forward, the wheels 4 roll in the direction of arrow E due to ground resistance, and together with the wheels 4, the axle 6 chain wheel 13 fixed to
rotate at the same time, and the rotational force is transferred to transmission chain 1.
5 to the chain wheel 14. Therefore, since the lower pulley 8 with the chain wheel 14 is driven, the belt 11 wound around the lower pulley 8, the front pulley 9, and the rear pulley 10 runs around in the traveling direction.
The conveyor plate 12 attached to the belt 11 is also conveyed in the traveling direction. When the Konniyaku sweet potatoes A loaded in the seed box 18 are fed one after another into the input section B between the conveyor plates 12, the Konniyaku sweet potatoes A are conveyed in the direction of travel and are pushed through the front pulley 9. When it crosses over, it is placed on the conveying plate 12 and conveyed downward. When the conveyance plate 12 is lowered, since the receiving surface 12' side of the conveyance plate 12 is formed into a shallow ∨ shape, the potato A is fixed to the center of the conveyance plate 12 and does not roll sideways, but instead moves to the center. When the sweet potato A is conveyed to the lower pulley 8 in a stable state, the belt 11 changes its direction upward according to the circumference of the lower pulley 8, and the conveyor plate 12 also changes every moment. By changing the receiving angle of
Since the front cover 16 is disposed on the front side of the lower pulley 8, it is temporarily stopped from falling to the ground, and when the conveyance plate 12 further moves, the front cover 16 and the conveyance plate 12 are quickly disposed. Since the gap is larger than the size of potato A, it will fall to the ground at this time. At this time, it is possible to drop the bud to the ground with it facing upward, but in this case,
On the inside of the cover plate 16, the upper end of an elastic plate 17 such as a rubber plate is fixed and suspended at the upper end of the cover plate 16, and a gap is left between the cover plate 16 and the elastic plate 17. When the potato A hits the elastic plate 17, the weight of the sweet potato A causes the elastic plate 17 to escape and curve, causing the sweet potato A to gradually move downward and come out from the elastic plate 17, causing the elastic plate 17 to It is restored to a flat plate shape, and the sprouts of potato A slide into contact with the lower part of the elastic board 17, adjusting their posture so that they are facing upwards and falling along the elastic board. Because the shape of the potato is not uniform, the movement of each potato when falling is different, but the elastic plate absorbs the energy of these different movements, and the shape of the potato is different. Since the falling posture of the bud can be adjusted, the bud can maintain a stable posture until it reaches the ground, and even after falling, the bud can remain almost upward. Furthermore, the interval between falls can be made almost constant. Also, as shown in Figure 4, if one or more slits S are attached to the bottom of the elastic board, the flexibility of the elastic board will be supplemented, and the contact with the sprouts of potato A will be softened, making it easier for the buds to slide. Since there is no need to correct the posture with excessive force due to contact, the buds are protected and accuracy is increased. In addition, it can also be used as a planting machine for taro and other sprouted bulbs.

Due to the above-described structure and operation, the present invention allows the elastic plate 17 to be appropriately deformed by the weight of the potatoes when planting the potatoes, thereby preventing a change in the direction or position of the potatoes near the lower pulley 8. The elastic plate 17 absorbs the energy of the movement of the sweet potato caused by the potato, and the elastic plate 17 acts to compensate for the sprout when the sweet potato falls, which is an essential condition. It has the advantage that it is easy to plant the plants facing upwards, and that they can be planted at even intervals.
