Description

[Detailed description of the invention] In this invention, a floating plate 2 is provided on the outer periphery of the short pipe 1, and irregularities 3 and 4 are provided on the outer periphery of the plate 2 in the same plane as the plate 2. A plurality of blade plates 5 are provided on the side surface, and the blade plate 5 extends from the short pipe 1 to the middle of the side surface of the floating plate 2, and from the middle to the outer periphery there is a surrogate blade with the same side surface formed flat. This relates to a desk crawler for use.

The short pipe 1, the floating plate 2, and the blade plate 5 are integrally molded from synthetic resin, and the short pipe 1 and the floating plate 2 are concentric and have unevenness 3, 4.
is formed into a waveform as shown in FIGS. 4 and 5.

It is preferable to provide four blade plates 5 at an opening angle of 90 degrees, and the proximal end is connected to the outer circumferential surface of the short pipe 1, and the distal end is connected to the floating plate 2 (radius 20 degrees).
CR! It is located at a radius of 172 of radius 1) (in the middle of the side surface), and is formed flat from its tip to the irregularities 3 and 4 on the outer peripheral edge.

In the figure, 6 indicates a horizontal shaft on which the short pipe 1 is freely fitted, 7 is a tilling rotary of the tractor, 8 is a machine frame of a working machine, 9 is a link between the machine frame 8 and the horizontal shaft 6, Reference numeral 10 is a vertical adjustment lever for the horizontal shaft 6, reference numeral 11 is a ground leveling plate, and reference numeral 12 is a tail wheel.

Therefore, as shown in FIGS. 1, 2 and 3, the horizontal axis 6
Short pipes 1 are installed in parallel in a freely movable manner, water is applied to the rice field after wheat harvesting, and when the tractor and tilling rotary 7 are operated to till the rice field, the lower part of the multiple parallel floating plates 2 at the rear of the tailwheel 12. The waist slat 5 rolls around the horizontal axis 6 in contact with the ground 13 of the paddy field, and rolls downward below the water surface 14, but without contacting the soil surface 15 below the water surface 14.

This transfer is caused by the movement of the floating plate 2 due to the running of the tractor, which causes the water 14 in the paddy field to push the blade plate 5 backwards, and the pressure causes the blade plate 5 and floating plate 2 to roll in the direction of the arrow, and the unevenness 3 and 4 on the water surface. Wheat straw, its stumps, grass, etc. floating on the soil surface 14 can be pushed into the soil surface 15 and inserted into the soil surface 15 in an upright state.

In conventional desk rollers for puking, when the floating plate is moved by the running of the tractor, if the horizontal axis that supports the floating plate tilts due to irregularities in the ground, excessive force is applied to the floating plate and it is easily damaged, and the floating plate is a flat plate. This defect is caused by the fact that the water resistance caused by the tractor's movement is low, making it difficult for the water to roll, and the force to push straw, stumps, grass, etc. floating on the water surface into the soil surface is weak, making it difficult to insert them into the soil surface in an upright position. was there.

The present invention was developed in view of the above-mentioned defects, and since the present invention is constructed as described above, when the floating plate 2 moves due to the running of the tractor, the horizontal shaft 6 supporting the floating plate 2 may tilt due to irregularities in the ground, etc. However, because of the blade plate 5, the floating plate 2 is reinforced and is not easily damaged even if an excessive force is applied. The flat side surfaces can easily penetrate into the soil surface 15, and the unevenness 3 and 4 have a strong force to push wheat straw, its stumps, grass, etc. floating on the water surface into the soil surface 15, and insert it into the soil surface 15 in an upright position. As a result, there are benefits such as preventing rice plants from being left out in rice transplanting operations using rice transplanting machines and eliminating the need for supplementary planting after rice transplanting.
