Description

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

In other words, the soil leveling device slides along the track of the wheels, making it possible to perform planting and leveling of the ground from the wheel tracks without flooding the planted seedlings with muddy water, and has a simple structure. The purpose of the present invention is to provide the following information so that it can be carried out suitably.

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

Figure 1 shows a plan view of a 4-row rice transplanter, with a main float (1) running in the front and back direction at the bottom of the machine, and short auxiliary floats (2) (2) on both sides. However, on both sides of the main float (1) near the middle in the front-rear direction and on the inside middle of both auxiliary floats (2) (2), there are leveling sections (la) (Ia) for leveling for planting seedlings. ), (2
a) Form (2a) into a slightly protruding shape, and form a large space behind the flat parts (la), (la), (2a) and (2g) that opens rearward to the rear end of the float. The structure is such that the rear of each leveled portion is the planting position (a) by the planting claws (3).

An engine (E) is mounted above the front side of the main float (1), and both auxiliary floats (2) ( 2
) are provided with wheels with lugs (4) (4), respectively, and both axles (4) are installed at the rear of both swing transmission cases (5) (5) extending rearward from both sides of the engine (E). 4)(4
) are installed so that transmission can be freely transmitted, and the transmission cases (5) (5
) The front parts of both auxiliary floats (2) (2) are supported by support rods (6) (6) extending to both sides of the front part of the main float (1). A handle (7) (7) is extended to the upper part, and a seedling planting depth adjustment rod (8) installed between the float and the fuselage side is installed so that the float can be adjusted up and down. ) (7) The seedling stand (9) installed diagonally in front of the 4
The structure is such that each planting claw (3) of the book can scrape off the seedlings from the lower part of the seedling stand (9) and plant the seedlings at each planting position (a).

In addition, within the hollow opening formed by each of the floats (1), (2), and (2), on the rear side of the planting position (a), and behind both axles (404), Ground leveling body (
A) (A) is installed, but the ground leveling body (A) has an inclined plane from the wide rear part (10) to the narrow front part (11)! (1, 2) (12) are extended and formed into a substantially triangular shape, and the supporting metal fittings (14) are joined to the round pipe support 7 frame (13) installed horizontally in the upper part of the fuselage. Insert both ends of the U-shaped rod (15) that engages the frame (13) into the support metal (14), insert a bottle (16) into one end, and attach a butterfly nut to the other end (17) are screwed together and can be tightened freely, and a bottle (18
) and a torque spring (19), the upper part of the support rod (20) is rotatably connected so that the support rod (20) is elastically biased forward, and The lower part of the support rod (20) is rotatably connected to the support piece (21) fixed on the upper surface of the section via a pin (22) and a torque spring (23). It is installed and configured so that it is pressed against the rice field.

6 to 10 show different embodiments, and in the embodiment shown in FIG. 6, the lower ground-contacting part of the rod that hangs from the support frame (13) is shaped like a U, and the ground leveling body (
In Fig. 7, a large number of rods are installed vertically in a comb-like shape to form the ground leveling body (A), and in Fig. 8, the plate body is bent forward to form a horizontally elongated structure. A ground leveling body (A) is formed and this ground leveling body (A) is urged downward by a spring (30), and in Fig. 9, the ground leveling body is bent forward into an inverted ■-shaped chevron shape. form a body (A), and put this earth leveling body (A) into a bin (3
1) and the bottle hole (32), the vertical position can be changed. In Fig. 10, a wide plate is made into a boat-shaped sled to form the earth leveling body (A>), and the tip is fixed by a spring (33). The part is biased so that it rotates upward.

The rice transplanter moves forward in the direction of arrow (c) using both axles (4) (4), and the main float (1) and both auxiliary floats (2) (2) slide on the rice field. The planting position fi of the rice field leveled by the leveling section (la) (la), (2a) (2a)! Each planting claw (3) plants 100 seedlings in (a), and planting is carried out so that four rows of planted seedlings (b) are formed as shown in Figure 4.

In this state, the leveling body (A) shown in Fig. 5 is arranged in rows (B) (
The ground leveling body (A), which is tilted under the pressure of the torque springs (19) and (23), smoothes the tracks left by the wheels (4) between the wheels (4) and slides on the rice field between the wheels (4). The ground is leveled so that it is level, but the leveling body (A) is located behind the planting position (A) and behind the wheels (4), so it does not interfere with the flow of muddy water and does not push mud onto the planted seedlings. It is possible to level the ground without having to do so.

In this way, the present invention has a main float (1) at the bottom of the fuselage.
Auxiliary floats (2) (2) are installed on both sides of the main float (1), and both auxiliary floats (2) (2) are installed on both sides of the main float (1) near the center in the longitudinal direction, and both auxiliary floats (2) (2) near the middle of the main float (2) in the longitudinal direction. Cut out the inside to create a large space between each float (1), (2), and (2), and place the front of this space at the planting position (
b), while disposing wheels (4) (4) between each float (1) (2) (2), and
(1) (2) In the space formed by (2), at the rear side of the planting position (A), and at the rear side of the planting position (A), and with the wheels (4) (
4"), a ground leveling body for leveling the wheel marks was installed so that it was supported by the aircraft so that it could slide onto the rice field.
Although soil leveling bodies are installed between each float, seedlings can be planted in the weak spots where the muddy flow passing between the floats has been weakened, and wheel marks can be leveled afterwards. Therefore, it is possible to prevent the deterioration of the planting posture of seedlings and the reduction of the soil leveling effect due to this muddy water flow, and to minimize the negative effects of muddy water flow to ensure reliable planting and complete land leveling. This has an extremely remarkable effect.
