Description

[Detailed explanation of the idea] The present invention relates to a wheel trace leveling device for a rice transplanter.

In other words, the ground is leveled by sliding the ground leveling plate following the tracks of both axles, and even if the planting depth is adjusted, the ground contact angle of the leveling plate remains constant and good leveling performance can be maintained. The present invention provides a simple structure that can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a plan view of a four-row rice transplanter. A main float 6 that is long in the front and back direction is installed at the bottom of the waist body, and short auxiliary floats 7 and 7 are installed on both sides of the main float 6. 6
7. Both sides and both auxiliary floats at the middle rear of the
7 has recesses 6a, 6a, 7a, ?, which serve as planting positions by the planting claws 8, on the inside at the middle part of the planting claws 8, respectively. a, and the rear part of each float is formed narrow from each recess to the rear end.

An engine E is mounted above the front side of the main float 6, and the recesses 6a, ? Wheels with lugs 1, 1 are located between both sides of the main float 6 and both auxiliary floats 7.7 in front of the position a.
are respectively arranged, and both axles 1, 1 are installed at the rear of both swing transmission cases 9, 9 extending rearward from both sides of the engine E.
The main floats 6 and 7 are connected to each other so that the front parts of the two auxiliary floats 7 and 7 are supported by supports 10 and 10 that extend to both sides of the front parts of the transmission cases 9 and 9, respectively.
A handle 11.11 is extended rearward from the rear of the float, and a seedling planting depth adjustment rod 12 installed between the float and the fuselage side is installed so that the float can be adjusted up and down.
1. The seedling platform 13 installed obliquely in front of the seedling platform 11 is movable horizontally so that each of the four planting claws 8 scrapes the seedlings from the lower part of the seedling platform 13 and places the seedlings in each planting position. It is constructed in the same way as the conventional type so that it is planted.

A support frame 5 made of a round pipe is fixed horizontally to the rear of the lower part of the seedling stand 13, and the upper part of a support metal fitting 15 having a U-shaped cross section is joined to the rear surface of the support frame 5. Insert one end of the U-pole rod 16 that is engaged with the U-pole rod 16 into the upper notch 15a of the support metal fitting 15, and insert the retaining pin 17 into one end of the U-pole rod 16, and insert the U-pole rod 16 into the hole 18 on the rear surface of the support metal fitting 15. Other end threaded portion 16
A wing nut 19 is screwed onto a from the outside, and a bent portion 2at3a is bent in the corresponding direction on the upper part of the parallel link 2.3 which is in the front and back position and also shifts in the lateral direction.
Bent portion 2a at the front and back of the lower part of 5.

A stopper 20 is formed at the front of the lower part of the support fitting 15 to prevent the link 2 from rotating forward from the vertical position, and a tension type spring 4 is inserted.
It is constructed by hooking one end of the hook 4a onto the bent portion 2a.

A is a leveling plate, which has a narrow front end 21 and a wide rear end 22, and has sloped side edges 23, 23 from the front end 21 to the rear end 22, so that muddy water can flow above them. A U-shaped support plate 24 is fixed to the upper center surface of the ground leveling plate A, and bent portions 2b are bent in corresponding directions at the lower portions of the parallel links 2 and 3.
, 3b are inserted into the front and back of the support plate 24 so as to be freely rotatable, and the other end hook 4b of the spring 4 is hooked on the bending part 3b. The installation is configured so that A is tilted forward.

In addition, both leveling plates A and A are installed vertically so that they are located behind the planting position A and behind the wheels 1 and 1, respectively.

Then, with the rice transplanter moving forward in the direction of the arrow by both axles 1, 1, and the main float 6 and auxiliary floats 7 and 7 sliding on the rice field, each of the four planting claws 8 is at the planting position A. Planting is carried out respectively, and the ground leveling plates A and A follow and slide on the tracks left by both axles 1 and 1 to level the ground.

In this state, the leveling plates A, A supported by the parallel links 2, 3 are tilted forward and slide on a circular surface while being pressed toward the field side by the spring 4, leveling the ground by leaving the marks of the wheels 1, 1. However, even if the planting depth is adjusted by operating the seedling planting depth adjustment rod 12, the leveling plate A does not change its attitude due to the support of the parallel links 2 and 3, and it continues to spread the rice field while being pressed by the spring 4. Can glide.

In addition, when the ground leveling plate A is sliding on the rice field and leveling the ground, the rear end 2
Since the two side edges 23, 23 are low, it is possible to prevent muddy water from overflowing above them and washing away the planted seedlings on the sides.

Note that by loosening the wing nut 19 and rotating the whole body around the support frame 5, it can be raised upward, and by tightening the wing nut 19, the whole body can be stored upward.

In this way, the present invention is equipped with a main float that is long in the longitudinal direction at the bottom of the fuselage, and short auxiliary floats on both sides of the main float. The rear part of each float is cut out to have a large space between each float, and the front part of the space is used as the planting position. In the large space at the rear, leveling plates are installed so that they can be slid against the rice field behind both axles at the rear side of the planting position so that the ground leveling plates that are inclined at the front height can be leveled and leveled with the wheel marks. Parallel links for support and springs for pressing the field side are interposed on the support frame side of the aircraft body, and the ground leveling plate is installed so that it can move up and down while maintaining its posture. The ground leveling plate can be slid to follow and level the ground, and even when adjusting the planting depth, etc., the ground leveling plate does not change the forward tilted posture, keeping the ground contact angle constant and leveling while applying just the right amount of pressure. It has the characteristics that it can level the ground without changing its performance, and that it has a simple structure and can be suitably implemented.

Furthermore, although the present invention provides a wheel track leveling device between each float, it is possible to plant seedlings when the flow of muddy water passing between the floats is weakened, and to level the ground from the wheel tracks afterwards. As a result, the effect of muddy water flow on the seedlings at the time of planting can be extremely minimized.As a result, the seedlings are planted when the muddy water flow is fast between the float and the wheel track leveling device, unlike conventional methods. It has the characteristic that it can solve the problem of difficulty in maintaining a certain planting posture.
