Description

[Detailed explanation of the invention] When planting 2-year-old and 3-year-old Konniyaku potatoes mechanically, at the time of planting Konniyaku potatoes,
The buds have grown several times, so be careful not to damage them.
In addition, since it is necessary to plant the buds with the buds facing upward, a long hole in the rotational direction is provided in the center of the conveying belt, and a large number of conveying plates are planted perpendicular to the circumferential direction of the belt. The lower pulley and the front pulley, which are about to be wrapped around each other, are each provided with a space corresponding to the long hole in the belt in the center, and the long hole in the center of the belt that runs around as the lower pulley rotates due to being driven by the drive wheel. By inserting the sprouts of potatoes facing downwards, the potatoes will be transported downwards as the belt runs around, and when the belt turns around, it will be placed at the front of the lower pulley. The Konniyaku potato planting machine was installed in such a way that the buds of the Konniyaku sweet potatoes are supported by the action of the front cover until they point upwards, so that when the Konniyaku potatoes fall to the ground, the sprouts are facing upwards. If the sprouts of sweet potatoes are straight, they will easily pass through the gap in the center of the lower pulley and front pulley, but if the sprouts are curved laterally, In this case, the bud hits the part of the pulley that receives the belt and gets caught between the belt and the pulley, causing damage to the bud. Therefore, we installed a pair of guide plates approximately parallel to each other at a position wider than the width of the long hole in the belt, with the tips of each facing the gap in the center between the lower pulley and the front pulley. This problem is solved by correcting the orientation of the potato sprout so that it can easily pass through the gap in the center of the pulley so that it does not touch the pulley.

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. Reference numeral 4 indicates a left wheel, and 4' indicates a right wheel, which are fixed to both left and right ends of a wheel 6 which is rotatably supported by bearings 5 and 5' disposed on the left and right lower sides of the machine frame 2, respectively. Reference numeral 7 denotes a support rack for supporting a pulley (described later), and is composed of a left support rack 7' and a right support rack 7'', each of which has its lower end fixed to the front part of the machine frame 2 and stands up parallel to the left and right. The upper portions of portions a and a' are inclined rearward at the same angle of inclination on the left and right sides, and overhang portions b and b' are provided at the upper ends of the rising portions a and a', which are bent and extended rearward in parallel to the left and right.
9 is a lower pulley that is rotatably supported at the lower part of the support rack 7, and 9 is a front end of the overhangs b and b' on the upper part of the support rack 7 in 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
is a rear pulley that is rotatably supported on the rear end of the overhanging parts b, b', and includes at least the lower pulley 8 and the front pulley 9.
Leave a gap in the center of each pot so that the potato sprouts can pass through easily. 11 is the pulley 8,
Belt wrapped around 9 and 10, 12 is belt 1
1, the surfaces of the conveyor plates 12 are perpendicular to the longitudinal direction of the belt 11, and between the respective conveyor plates 12, the belt A long hole 16 is opened in the center of the tube 11 in the direction of propagation, and the hole 16 is wide enough to allow the sprout of the potato to enter easily. Note that the receiving surface 12' (that is, the surface that faces upward when descending) of the conveying plate 12 planted on the belt 11 forms a shallow V shape centered on the center of the long hole 16 bored in the belt 11. . Then,
The surface of the portion of the belt 11 that hangs between the lower pulley 8 and the front pulley 9 has an upwardly inclined rearward surface due to the relative position of the lower pulley 8 and the front pulley 9. 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;
4 is a chain wheel attached to the lower pulley 8, and 15 is a chain wheel 1.
3 and the chain wheel 14 to transmit the power generated by the rolling of the wheels 4 and 4' to the lower pulley 8. A front cover 17 is fixed to the machine frame 2 and covers the front side of the conveyor plate 12 installed on the belt 11 around the lower pulley 8 . The input section B into which the Konniyaku sweet potatoes A are placed is set almost horizontally.
The lower end of the front cover 17 is provided between the horizontal line and the vertical line at the center of the lower pulley 8, and is opened so that the potatoes A can fall to the ground, and the potatoes A can be thrown into the input section B. This prevents the front cover 17 from falling off the conveyance plate 12 while being conveyed from there to the lower end of the front cover 17. 18 is a left guide plate, and 18' is a right guide plate, which is composed of a pair of left and right guide plates. Opposing guide surfaces are formed to maintain an interval that allows the sprouts of sweet potatoes to easily pass through, and each tip thereof faces the gap in the center of the front pulley 9, and the length of the belt 11 is They are arranged substantially parallel to each other at a position wider than the width of the hole 16. 19 is the left information board,
Reference numeral 19 denotes a right guide plate, which is composed of a pair of left and right guide plates, and each outer side is connected to the left and right rising parts a,
a′, and each inner side forms a left and right opposing guide surface to maintain a gap that allows the potato sprouts to easily pass through.
They are arranged almost parallel to each other at a position wider than the width of 6.
Numerals 20 and 20' are seed boxes for loading Konniyaku potatoes that are mounted on support racks 7' and 7'', and the lower ends are fixed to the machine frame 2 and the upper ends of the left and right pillars 21 and 21' stand up. 22 is a groove cutting plate that opens a groove in the soil surface in which the sweet potatoes A are dropped and arranged in close proximity to the front of the lower part of the front cover 17, and 23 is the groove cutting plate 2.
This is a mounting rod whose lower end is fixed to the front part of the machine frame 2, and which is fitted into a support 24 fixed to the front part of the machine frame 2 to fix the groove plate 20 so as to be vertically adjustable in height. Arrow E indicates the direction of rotation of wheels 4, 4'. C is the surface of the field. D
indicates the groove bottom.

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 and 4' roll in the direction of arrow E due to ground resistance, and the wheels 4 and 4' roll in the direction of arrow E due to ground resistance. .
Therefore, since the lower pulley 8 equipped 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, and the belt 11 Planted conveyor board 12
are also transported in the forward direction. In this case, in the present invention, a gap is provided in the center of the lower pulley 8 and the front pulley 9 so that the potato sprouts can easily pass through, and a gap is provided between the belts 11 between each conveyor plate 12. There is a long hole 1 in the center facing the direction of travel.
6 and a long hole 16 wide enough for the Konniyaku sweet potato sprouts to fit through easily. When the potatoes A are fed one after another in the opposite direction from the input section B with the sprouts facing down, the potatoes A are quickly conveyed in the direction of travel. By forming a shallow V-shape centered on the center of the elongated hole 16 attached to the belt 11, the potatoes are quickly fixed to the center of the conveyor plate 12 and are kept stable in the center without rolling sideways. When the sweet potato is conveyed to the lower pulley 8, the belt 11 changes its direction upward according to the circumference of the lower pulley 8, and the conveying plate 12 also changes its receiving angle moment by moment. The receiving angle is now pointing downwards, and soon potato A will fall downwards.
In this case, since the front cover 17 is disposed in front of the lower pulley 8, it is temporarily prevented from falling to the ground, and when the conveyance plate 12 moves further, the front cover 17 and the conveyance plate 12 are separated. This creates a gap that is larger than the size of potato A, so it will fall to the ground at this time. At this time, the konnyaku potatoes are turned upside down compared to when they were put in, allowing them to fall to the ground with the sprouts facing upwards, and the intervals at which they fall are almost constant. Not only the sprouts of Konniyaku sweet potatoes grow straight, but also those that are severely curved to the side. That is, the sprouts of Konniyaku potato A are located on the left and right guide boards 18,1.
8' and the gap in the center of the front pulley 9. However, if the bud is severely bent, if there are no guide plates 18, 18', the bud will pass through the front pulley 9. Although the left and right guide plates 1 may be pinched and damaged between the circumferential surface of belt 9 and the back surface of belt 11,
8 and 18', the direction of the sprout is corrected so that it can pass through the gap in the center of the front pulley 9 without touching the front pulley 9, so the potato A can now pass through the front pulley 9 without damaging the sprout. The sprouts of potato A then pass through the gap in the center of the lower pulley 8. Since the bud passes between the left and right guide plates 19, 19' beforehand, the direction of the bud is corrected by the left and right guide plates 19, 19' in the same way as when passing through the front pulley 9. Since the sprouts are allowed to safely pass through the gap in the center of the lower pulley 8, the sprouts of potato A can be planted without damaging them at all.

As described above, the present invention arranges the front pulley 9 above the lower pulley 8, and the front pulley 9 and the rear pulley 10.
A belt 1 in which a large number of conveyor plates 12 are equally distributed
1 is wound around the belt 11, and the belt 11 has a long hole 16 facing in the traveling direction between the conveyor plates 12 at the center.
At least the front pulley 9 and the lower pulley 8
What does this mean? A gap is created in the center to match the width of the long hole 16 attached to the belt 11.
In the Konniyaku potato planting machine, in which only both edges of Konniyaku potato A are received by the front pulley 9 and lower pulley 8, the sprout of Konniyaku potato A is placed in the center between the front pulley 9 and the lower pulley 8. It is possible to pass through the gaps in the
In addition, since the left and right guide plates 18, 18' and the left and right guide plates 19, 19' are arranged respectively, with their tips facing the gap between the front pulley 9 and the lower pulley 8, the guide plates will not cause the bending. Even if an ivy bud occurs, correct its direction so that the belt 11 and front pulley 9 or lower pulley 8 can safely handle the bud without pinching the bud.
Because it can pass through the gap in the center of
Since the buds are not damaged, the above-mentioned structure has the effect of allowing the buds of sweet potatoes to fall upward to the bottom of the furrow without causing damage to the buds.
