Description

[Detailed description of the invention] This invention is designed to level the wheel marks using a leveling tool placed behind the running wheels, and to prevent the seedlings from being disturbed in their posture when planting at the rear. Regarding the rice transplanter.

The above-mentioned ground leveling tool for leveling wheel marks can be used to level wheel marks without being affected by the hardness or softness of the mud by turning it downward. There is a risk that the rotation of the rotating pivot portion will be hindered by the scattering of mud as the traveling wheels rotate, making it impossible to perform the leveling work as expected.

In view of these circumstances, the present invention reliably prevents mud from scattering to the rotational pivot portion of the ground leveling tool by effectively utilizing its original function by selecting the location of the rotational pivot portion of the ground leveling tool. The purpose is to ensure that the ground leveling tool operates as expected over a long period of time.

Next, embodiments of the present invention will be described based on the drawings.

A transmission case 1 for vehicle speed change is connected to the engine E mounted at the front of the aircraft, and wheel transmission cases 3, 3, in which driving wheels 2, 2 are rotatably mounted on both left and right sides of the mission case 1, are mounted on the horizontal axis. The rear end of a frame 15, which also serves as a transmission case and which is pivotally connected around a core so as to be able to swing up and down and extends rearward from the rear of the transmission case 1, reciprocates the seedling tray 4 in a forward-tilting position from side to side. The planting device 7 is connected to the front end of a feed case 16 containing a built-in transverse feed shaft 4a, and the planting device 7 is connected to a planting case 17 extending rearward from the feed case 16 and containing a built-in power transmission shaft (not shown). is installed, and the seedling planting claw 5 is configured to be driven in a reciprocating circular rotation so as to draw an elliptical trajectory, and the long flows 1 to 6 in the longitudinal direction of the machine are arranged.
. . . integrally with its rear end side facing rearward from both ends of the pipe-shaped horizontal shaft 18 that is supported in a hugging state by the recess 16 a on the lower surface of the feed case 16 and the U-shaped metal fitting 13. Bracket 1 is attached to extended arm 18a.
9 are pivotally connected, and the rear end side is centered and the front end side is connected to the fuselage via a bending link 20 so as to be vertically swingable.
The seedling planting device 7 is maintained at a constant height on the mud surface by the buoyancy of the wheels 2, 2 and the ground reaction force of the wheels 2, 2. This is a walk-behind rice transplanter for taking out one seedling block from a mat-like seedling using the seedling planting claw 5 and planting it at a constant depth under the mud surface.

At the rear position of the left and right running wheels 2, 2, a ground leveling plate 8 formed by a plate spring is clamped and attached to a bracket 9 by an elastic piece 10a made of a stronger plate spring, and this bracket 9 is attached to the aircraft body. A coil spring 10b is provided between the elastic piece 10a and a bracket 21 fixed to the body, and the grounding plate 8 is rotatably biased downward. Ground leveling tool 10
As the aircraft advances, the leveling plate 8 is inserted into the passage grooves of the wheels 2, 2 and the periphery thereof, leveling the grooves and removing mud near the seedling planting device 7. Planting is structured to suppress flow and prevent disturbance of seedling posture.

On the front surface of the feed case 16 between the running wheels 2 and the seedling planting device 7, mud from the side of the running wheels 2 spreads from the transverse feed shaft 4a of the seedling platform 4 to the lower end of the feed case 16. A mud cover 11 is provided to prevent mud from scattering onto the transverse feed shaft 4a of No. 4 and the rear seedling planting device 7.

This mudguard cover 11 and a bracket 12 for attaching the ground leveling tool 10 are attached to the feed case 16 via bolts 14.

In other words, by positioning the pivoting support A consisting of the horizontal axis X and the bracket 12 on the back of the mudguard cover 11,
The structure is configured to reliably prevent mud from being scattered by the wheels 2 onto the rotation pivot A, so that the ground leveling tool 10 can perform its function as expected over a long period of time, and the wheel marks can be well leveled. It is designed to make it easier to understand.

In summary, the characteristic configuration of the rice transplanter of the present invention is that a forward-leaning seedling rest is provided at the rear of the running wheels, and the seedling rest is moved left and right through a transverse feed shaft provided in the feed case. At the same time, mud from the running wheels is deposited on the front side of the feed case from the horizontal feed shaft of the seedling rack to the lower end of the feed case. In a rice transplanter equipped with a mud cover that prevents mud from scattering on the device, a ground leveling tool for leveling wheel marks is supported in a feed case portion located at the back of the mud cover so as to be able to swing up and down. The main feature is that the pivot parts are connected in a row, and this configuration provides the following effects.

In other words, by effectively utilizing a cover to prevent mud from scattering on the horizontal feed shaft of the seedling stand, and setting the pivot position of the soil leveling tool at the back of the cover, the lateral movement of the seedling stand can be easily achieved. It is possible to form a wall that is almost continuous from a relatively high position corresponding to the height of the feed shaft to the mud surface, which eliminates the need to provide a long mud cover downward, or to level the ground. Even if the top end of the tool is not longer than necessary, the planting device and planting device can reliably prevent mud from scattering from the wheel side on the seedlings. Without adding a new structure to prevent mud from scattering to the pivot, the original mud guard function can be effectively utilized to reliably prevent mud from scattering to the pivot, allowing the soil leveling tool to function as intended. It has been possible to maintain functionality for a long period of time.
