Description

[Detailed description of the invention] This invention relates to a float structure for a multi-row rice transplanter.

Conventional multi-row rice transplanters, for example, four-row rice transplanters, have a center float in the center of the lower part of the machine and side floats on the left and right sides to prevent the machine from sinking, to run smoothly, and to ensure proper planting. Maintains depth, etc.

In this invention, in the multi-row rice transplanter, the wing bodies are provided protrudingly on the left and right sides of the float, and the upper surface of the wing body is configured at a lower position than the upper surface of the float, and the wing body is placed in the planting area. It is an object of the present invention to provide a float structure of a multi-row rice transplanter that can effectively level the planting area by configuring it to be located at the front.

To explain the embodiment of this invention in detail based on the drawings, A is a four-row rice transplanter, with an engine 1 at the front, a transmission section 2 at the rear, and four rice transplanters at equal intervals to perform four-row planting at the rear. The seedling planting section 3 is equipped with attached claws, and four seedling mats can be placed at the front and rear heights.The seedling block is cut and taken out from the seedling outlet at the lower end using the planting claws, and four rows of seedlings are planted. A seedling stand 4 is provided on which the seedlings are placed, a handle 5 is protruded from the rear end, and wheels 6 are provided on the left and right sides of the machine.

Reference numeral 7 denotes the center float body, which has a narrow, approximately rectangular shape, and its width is slightly narrower than the mutual spacing between the planting claws.The front end extends to the front end of the body, and the rear end extends to the end of the seedling platform 4 It extends all the way to the end, and by being hollow, it functions as a float to keep the aircraft above the water surface.

Reference numeral 8 denotes a wing body protruding from the left and right sides of the center float body 7, and the left and right width of the wing body is configured to be the same length as the width of the wide part of the conventional center float body, and the upper surface of the wing body is designed to be similar to the center float body. The wing body is configured to be slightly lower than the upper surface of the float body and protrudes from the center float body so that the wing body is located in front of the seedling planting section 3.

Reference numeral 9 denotes a longitudinal convex body provided at the center of the bottom surface over approximately one-third of the front part of the center float body 7, protruding slightly downward from the bottom surface, and evenly separating muddy water from side to side at the tip of the center float body. and maintain float straightness.

10 is a planting depth adjustment lever provided at the rear end of the center float 7, and 11 is a locking device provided at the front end of the center float 7, which fixes the center float main body at a constant distance from the aircraft body. , 12 is a float sensing body, which causes a hydraulic system to sense the vertical movement of the float and swings the wheels. 13 is a side float provided on the left and right sides of the center float body 7.

The embodiment of this invention is constructed as described above, and while the body is held by the center float body 7 above the water surface of the field, it is moved by the wheels 6 and the seedling planting part 3 is operated. , the seedlings are cut from the seedling stand 4 and planted in the field, and the seedlings are planted while the vehicle is running.
Water currents are generated on both sides of the center float body 7 and tend to flow toward the seedling planting area at the rear of the center float body 7, but the wing body 8 is disposed in front of the seedling planting area. Therefore, the deep water current can prevent the deep water flow from flowing laterally by hitting the leading edge of the wing body 8 and directly mixing into the seedling planting area 3. In particular, Since the upper surface of the wing body 8 is formed lower than the float upper surface, the upper layer of the water flow flows on the upper surface of the wing body 8 and reaches the rear, but the lower layer of the water flow is blocked by the leading edge of the wing body 8 and reaches the protruding end of the wing body 8. The upper water flow flows from above into the blank space directly behind the wing body 8, and the lower water flow that has detoured around and flows into the blank space on the rear side of the wing body 8. Even if the upper surface of the wing body 8 is flown straight from the front, the blank area directly behind the wing body 8 is filled to some extent, so a wraparound force of 9J is generated by the sudden water flow, and in the end, , the lower water flow hardly flows immediately behind the wing body 8 and the seedling planting part 3
□The blank space directly behind the wing body 8 is filled by inflows from two different directions: the upper layer water flow that goes straight and the lower layer water flow that detours. The force of the straight upper layer water flow is reduced by the detouring lower layer water flow from the lateral direction. This is to prevent the effects of water flow as much as possible, and if the top surface of the wing body 8 and the top surface of the float are kept at the same height as in the past, a blank space will be formed at the rear of the wing body 8 as it advances. In this case, the flowing water that detours around from the protruding end of the wing body suddenly flows in all at once, causing the flowing water with increased flow force to reach the seedling planting area, but this problem is prevented in this proposal. Therefore, the wing body 8 can sufficiently harmonize the water flow protection function and the float function.

According to this invention, the wing bodies are protruded on the left and right sides of the float, and the upper surface of the wing body is formed lower than the upper surface of the float, so the wing body itself has a float function on the left and right sides of the float, and the balance between the left and right of the aircraft is maintained. It can be effectively taken above the water surface and therefore,
The float itself can be formed to have a narrow width corresponding to the float function on the left and right sides of the wing body, and even though the float is narrow, the left and right wing bodies can perform the float function on the left and right width of the aircraft. The left and right balance of the aircraft can be effectively maintained, there is no need to create a wide float close to the left and right width of the aircraft as in the past, and the water surface resistance can be reduced by 9 points compared to such a wide float. The water flow that bypasses the tip of the wing body is caused by the upper layer of water flowing on the upper surface of the wing body flowing into the space directly behind the wing body from above and filling the space, causing it to rapidly flow behind the wing body. , and the straight upper water flow from the upper surface of the wing body is decelerated to some extent by the detour water flow from the side, which prevents the flow from increasing due to the sudden detour flow phenomenon of the water flow. The seedling planting part has the effect of preventing as much as possible the danger of water flow hitting the planted seedlings and causing the seedlings to rot.
