Description

[Detailed description of the invention] Conventionally, it is already known that a rice transplanter for planting pine seedlings has a hawk attached to the planting rod, but the width of the seedling receiving part of the hawk is equal to the width of the pair of left and right. Since the width was formed to be approximately the same as the inner width of the planting claw, when the planting claw scraped off the seedlings, the hawk would damage the spreading leaves of the seedlings, and also leave mud in the pocket of the hawk. The seedlings were easily clogged, and in this clogged state, the damage to the seedlings was even more severe.

Furthermore, when climbing up after planting, the hawk squeezes the leaves of the seedlings, damaging them and pulling out the planted seedlings.

In addition, in order to solve the above-mentioned problems, the cross section of the main part of the belt and the seedling receiving part at the tip thereof are both made into a U-shape, and the base side of the seedling receiving part is made wider than the tip part. Even if pressing, forging, or any other processing method is used to make the cross section of the seedling receiving part at the tip U-shaped, the cost will be extremely high, and the main part will be damaged during planting. The seedling soil remaining in the bent part of the container is pushed up and piled up, and it hardens, making the extrusion action unstable, and other problems occur, such as the planting depth of seedlings becoming deeper than the set amount. do.

The purpose of this invention is to solve the above-mentioned problems.A pair of left and right planting claws is attached to the tip of a planting rod, and the seedlings are pushed out on the inner back side of the planting claws. A hawk is provided, and the hawk is composed of a substantially inverted T-shaped plate consisting of a band-shaped portion and wing-shaped portions extending from both sides of the lower end of the hawk, and the wing-shaped portions are bent at their base sides and planted. U with opening on the claw side
It is formed into a letter-shaped seedling receiver, and the opening side of the seedling receiver approaches the inner surface of the planting claw, and the inner cavity gradually becomes wider as it moves away from the planting claw. It is characterized in that the other end is bent toward the planting claw and the upper end side to serve as an attachment part.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a planting rod, the middle part of which is supported by a crank pin 2 that moves in a circular motion by a crankshaft protruding from the planter case, and the base part of which is supported by a swinging arm 3 that is supported by the planter case. It is rotatably connected to the tip.

As shown in FIG. 7, a planting claw 4 consisting of a pair of left and right claw plates with an L-shaped cross section is screwed onto the tip of the planting rod 1, and the back part thereof (crank pin 2
A rod 6 with a hawk 5 screwed to its lower part is movable up and down, and the upper part of the rod 6 is connected to an operating rod that swings up and down by a cam attached to the crank pin 2.

Further, as shown in FIG. 2, the spring steel plate constituting the fork 5 has a substantially inverted T-shape or cross-shape consisting of a band-shaped portion and wing-shaped portions extending from both sides of the lower end of the band-shaped portion. As shown in FIGS. 3 to 5, the parts are bent at their bases and extended parts by press working to form a U-shaped opening on the side of the planting claw 4, and the width of the base is wider than that of the strip part. 7, and the tip portions 7a, 7a of the seedling receiving portion 7 are made substantially parallel to each other, and fit inside the left and right nail plates of the planting claw 4, and are directed toward the pocket portion 7b that is away from the planting claw 4. The inner width L of the pocket portion 7b (approximately equal to the width of the band-shaped portion) is larger than the inner width l of the tip portion, so that when the seedling receiving portion 7 pushes out the seedling, the base portion Even if seedling soil or mud is pushed up, it will fall from the base of the extension, and they will
They rarely adhere to the seedling receiver 7, and even if they do, they tend to fall off. Note that this effect is further improved by applying hard chrome plating to the entire surface.

While running the rice transplanter having the above-mentioned planting rod 1, the seedling platform is reciprocated from side to side, and when the planting rod 1 is moved up and down by rotation of the crank pin 2, the planting rod 1
The pine seedlings on the seedling table are scraped off one by one, lowered down, and planted on the rice field.

When the planting claws 4 scrape off the seedlings, since the width of the pocket 7b of the seedling receiving section 7 is wide, the planting claws 4 can easily pass through the leaves of the seedlings whose upper part is spread out from the base of the plant, and the seedlings can be placed on the field. When planting, the seedling receiving part 7 is not clogged with muddy soil, and when scraping the seedlings, the seedling leaves are not damaged by the clogged muddy soil.

Furthermore, when the hawk 5 rises together with the planting claw 4 after planting, the seedling receiver 7 that surrounds the planted seedlings has a wide pocket 7b, so it goes without saying that the leaves of the seedlings will not be damaged. There is no need to pull out the seedlings that have been planted.

In the present invention, as described above, a pair of left and right planting claws 4 are attached to the tip of the planting rod 1, and hawks 5 for pushing out seedlings are provided on the inner back surface of the planting claws 4. It is composed of a substantially inverted T-shaped plate consisting of a band-shaped portion and wing-shaped portions extending from both sides of the lower end, and the wing-shaped portions are bent at their base sides to form a U-shaped plate with the planting claw 4 side open. The opening side of the seedling receiving part 7 approaches the inner surface of the planting claw 4, and the inner cavity gradually becomes wider as it moves away from the planting claw 4. Since the other end is bent toward the upper end side of the planting claw 4 to form the attachment part, when bending it to form the seedling receiving part 7, the part to be bent becomes the base side of the wing-shaped part and forms a strip. There is no need to bend the entire portion, and the seedling receiving portion 7 can be bent into an accurate shape extremely easily.

Furthermore, even if bed soil or mud is pushed up along the base of the seedling receiving part 7 of the hawk 5 when seedlings are planted on the rice field, it will not fall off from the base that extends laterally from the strip. If the planting claws 4 scrape off the seedlings on the seedling stand, or if the planting claws 4 scrape off the seedlings, the seedlings will not get clogged. When planting and lifting, the leaves of the seedlings are not squeezed up, so there is no need to damage the leaves or pull out the seedlings.
