Description

[Detailed Description of the Invention] The present invention is intended to provide a potato cutting and sowing device having a novel configuration.

In the conventionally provided device 1 of this kind, as shown in FIG. 7, the rotary arm 1A has two arms spaced apart by 90 degrees from both sides of the cutting knife 1B and the partition plate 1C. The four arms are fixed to the rotary arm shaft 1D and are configured to rotate. On the other hand, the right pressure plate 1E and the left pressure plate 1F are the right bending rod 1G and the left bending rod 1.
The partition plate 1 is moved by the tension of the spring S through H.
C, and is configured to maintain a minimum distance from the partition plate 1C by stoppers 1I, 1J, and 1K. Therefore, potato 2 is rotary arm 1
By the rotation of A, the seeds are pressed against the knife 1B and cut, and are divided into left and right seeds 2A and 2B on the left and right sides of the partition plate 1C. These seeds 2A, 2B are supported between the left and right side pressure plates 1E, 1F and the partition plate, but are pressed downward by the rotating arm that moves further, and fall and are sown. but,
When the diameter of the potatoes increases, as shown in FIG. 9, one of the potatoes 2A rotates and cannot fall.
Furthermore, since the next potato is subsequently cut as shown in Figure 10, there is a problem in that two potatoes accumulate on one side and fall off at the same time. In addition, if it is necessary to narrow the space between plants, it is necessary to speed up the rotation of the arm, but if the rotation of the arm is increased in this way, variations between the plants become noticeable.

The present invention is intended to fully solve this problem, and the details of one embodiment thereof will be described below with reference to the drawings.

3 is the potato cutting and sowing device of the present invention. The configuration is such that a partition plate 3B is provided at a rear position in the rotational direction of the rotary arm shaft 3A at an angle perpendicular to the rotary arm axis, and a cutting knife 3C is provided on the rotary arm shaft side of this partition plate. installation,
The above rotating arm axis has left and right flat iron arms 3D,
An appropriate number of sets of 3E are fixed radially across the cutting knife and partition plate, and pressed from the outside to the inside at a constant interval on the left and right sides of the cutting knife and partition plate. Left and right pressure plates 3F and 3G are provided, and the lower edge of the right pressure plate among the left and right pressure plates is cut out at a position higher than the other lower edge, and the right pressure plate 3G is configured such that its lower edge can be adjusted up and down. has been done. A small protrusion 3D' is provided on the left arm so as to protrude in the direction of the left pressure plate, and a groove 3F' is formed below the left pressure plate into which the small protrusion is loosely fitted. 3H and 3I are supported by posture correction plates so that the upper part is wide and the lower part is pinched.
J is a curved rod that supports the left and right side pressure plates so as to press them in the direction of the partition plate. Therefore, the above-mentioned right pressure plate 3G
The vertically adjustable structure has a fan-shaped upper fixed plate 3.
A fan-shaped lower movable plate 3G'' is pivotally attached to G' by a pin P at the lower end.
The arcuate groove 3G provided at G'' is fixed with a thumbscrew 3G fixed to the upper fixing plate 3'.T is a knob.

Next, the function of the present invention will be explained along with its effects.

The seeds that have fallen from the bucket (not shown) are supported between the first two points on the upper part of the posture correction plates 3H and 3I, but the seeds are corrected on the left and right sides against the tension of the spring (not shown). Continue falling while pushing the board apart. At this time, the seed yam is supported between the two closest points in its form by the slope of the left and right posture correction plates and the tension of the spring. Then, as the rotation of the rotary arm progresses, this seed potato is pressed against the cutting knife, advances further, and is cut into the partition plate 3B.
It is divided into left and right. At this time, the seeds are supported between the left and right pressure plates and the partition plate by the action of the bent rod and spring. Furthermore, the seeds moved by the rotation of the rotary arm lose their support at the lower edge of the right pressure plate, which has a small angle at first, and fall. At this time, the cut half piece is supported between the left pressure plate and the partition plate, but as the rotation of the rotary arm progresses, it moves further, loses its support at the lower edge of the left pressure plate, and falls. By carrying out this operation continuously, the left and right halves are dropped alternately, thereby controlling the distance between the plants to a predetermined distance and sowing the seeds.
In particular, in the case of the present application, since the left arm has a small protrusion 3D' protruding from it, as shown in Figs. 5 and 6,
When pushing down the seed 2A with the arm, the small protrusion also comes into contact with it, so even in the case of potatoes with a large diameter, the problem pointed out at the beginning can be solved.
In addition, the height of the lower edge of the right pressure plate can be adjusted by moving the lower movable plate 3G'' according to the desired spacing between plants and the rotational speed of the arm, which eliminates variations among plants during sowing. Can be done.
