Description

[Detailed Description of the Invention] The present invention relates to a machine for planting potatoes such as Japanese yam and konnyaku yam while separating them for a predetermined period of time.

Generally, when planting potatoes such as rainbow, konjac and konjac potatoes, the parent potato is divided into multiple pieces to increase the number of individual potatoes and then planted as seed potatoes. Conventional planting machines transport a large number of seed potatoes stored in a hopper one by one using an ordinary conveyor, isolate them for a predetermined period of time, and then drop them onto cultivated land for planting. ), and the seed potatoes are planted in random orientations, sometimes facing up (down). However, seed potatoes planted with the outer skin facing downward and the cut surface facing upward will germinate about a week later than those planted with the outer skin facing upward, so if the seed potatoes are planted in a random orientation, growth will be sparse and the seed potatoes will grow sparsely. The disadvantage was that the farming work involved in raising the crops was troublesome. In addition, this type of planting machine has a disc-shaped seed removal plate that is rotated by another power source and has a plurality of forked pegs protruding radially from the seed box, and the seed potatoes are harvested from the seed box located below. A device was developed in 1973 to prick the seed potato, rotate it, and operate a two-pronged pricker with a cam plate at the height of the rotating shaft of the seed removal plate to drop the pricked seed potato.
It is known from Publication No. 21128. However, this device requires an additional power source to drive the seed removal plate, and the rotational force transmission mechanism between the power source and the seed removal plate, and the potato planting interval regardless of the advancing speed of the planting machine. This requires a means to keep the value constant, resulting in a complicated structure. In addition, because the seed potatoes are stabbed downward and removed and dropped at the level of the rotating shaft of the seed removal plate, the falling distance is long, and there is a high probability that the seed potatoes that have been stabbed will fall with their outer skins downward, making it impossible to ensure that their outer skins fall upwards. The drawback is that it cannot be done. Furthermore, a bifurcated pincer is required for each needle, resulting in a complicated structure and high manufacturing cost. The present invention aims to provide a practical planting machine that overcomes these drawbacks with a simple configuration.

This invention involves attaching a rotary ring 1 to the fuselage, which has a cross-sectional shape that touches the ground and rotates without power as the aircraft advances, and stingers 2 and 2' are separated by a predetermined interval in a recessed groove 14 in the center of the outer periphery of the rotary ring. A plurality of needles are provided, and the needles 2, 2' prick plants such as potatoes at a lower position near the ground contact position of the same rotating wheel.
The present invention relates to a planting machine characterized in that a scraper 3 which can be pulled out from a rotary wheel 2' and dropped is attached so as to be inserted into a recessed groove 14 of a rotary wheel 1.

In the figure, 4 is the machine frame, 5 is the rotating shaft of the rotary wheel, and 6 is a lug protruding from the outer periphery of the rotary wheel 1, which is attached to the machine frame 4.
When the wheel is towed and advances, the same lug kicks the soil and rotates the rotary wheel 1. 7 is scraper 3
8 is a spring that presses the scraper 3 against the rotating ring 1; 9 is pivotally supported on the machine frame 4;
The height of the rotating wheel 1 is adjusted by changing the angle and fixing the swinging rod. 10 is a connection part with a working vehicle, 11 is a saddle for riding, 12 is a tire, 13 is a footrest plate, 14 is a recessed groove for inserting the seed potatoes of the rotary wheel 1, 15 is a lug cover, 1
6 is a soil removal board. A is the seed potato, a is the outer skin of the same type of potato, and b is the cut surface.

In this invention, when the aircraft is advanced at a constant speed, the rotary wheel 1 that touches the ground and rolls rotates at the same circumferential speed. When the rotating wheel 1 reaches a predetermined position above,
A seed potato A cut into small pieces by an operator is inserted into pricking needles 2 and 2' of a rotary wheel 1 from its outer skin a, and fixed so that the cut surface b of the seed potato A faces upward or outward. The seed potato A is inserted into the needles 2 and 2' of the rotating wheel 1 one after another, and when the rotating wheel 1 rotates and the seed potato A comes close to the grounding point, the scraper 3 removes the seed potato A from the needles 2 and 2'.
It is pulled out from 2' and falls with the outer skin facing upwards. At this position of the scraper 3, the needle 2,
Since 2' is facing downward and the falling distance is short, the seed potato A that is pulled out and falls onto the cultivated ground will surely have the outer skin a side facing upward. Moreover, the planting interval of the seed potatoes A is the interval between the needles 2 and 2' of the rotary wheel 1, and is constant regardless of the traveling speed of the machine.

By making the cross-sectional shape of the rotary wheel 1 into a shape and providing a recessed groove 14 in the center, the strength of the rotary wheel 1 is not only increased, but also the manual stabbing operation of the seed potato A is performed by the raised side walls on both sides. Can be easily and quickly guided. Furthermore, the recessed groove 14 serves as a guide for the scraper 3 and has the function of stably operating the scraper 3.

As described above, according to the present invention, by having the configuration with the above characteristics, seed potatoes A can be reliably planted at regular intervals with the outer skin a facing upward.
Furthermore, since the rotary wheel 1 is grounded and rolls on its own, no special power source or power transmission mechanism is required, and the scraper has an extremely simple structure, so it can be manufactured at low cost.
