Harrow plate adjusting device for paddy field flattening machine

Abstract

The invention discloses a harrow plate adjusting device for a paddy field flattening machine, and belongs to the field of agricultural machinery. The harrow plate adjusting device for the paddy fieldflattening machine comprises a driving bevel gear and a driven bevel gear, wherein the driving bevel gear is connected with a universal joint of a rotary tillage rake universal joint; the driven bevelgear is close to a harrow; a transition bevel gear is engaged between the driving bevel gear and the driven bevel gear; an 'L'-shaped driven shaft is connected between the transition bevel gear and the driven bevel gear; the L-shaped driven shaft comprises a vertical portion and a transverse portion; the vertical portion is connected with the middle of the transition bevel gear; and the transverse portion penetrates through the driven bevel gear. When a rotary tillage rack drives the harrow to steer through the universal joint, the universal joint transmits steering moment to the driving bevel gear, at the moment, the driving bevel gear begins to rotate, after being stressed, the transition bevel gear which is engaged with the driving bevel gear transfers around a point where the verticalportion is connected with the transverse portion, during transferring, the transition bevel gear drives the driven bevel gear to rotate, and therefore, the steering moment is transmitted. After the technical scheme is adopted, dragging and sliding of the harrow plate during steering are improved, and meanwhile, the cultivated land area is broadened.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a paddle adjustment device for a paddy field leveling machine. Background technique [0002] In the traditional technique, the plow can only be operated in the paddy field, so it is called the water plow. After the water buffalo plows the field, the person stands on the plow, and the ox drags the plow to plow twice. Pieces are plowed and broken to make the field easy to plant. In some fields, the soil is compacted and beaten two or three times, and the last time is called Guanxu. People use their legs to press on the stalk sticks to make the sputum teeth tilt up, mainly to flatten the field and bring the soil from the high place to the low place to make the field level. The water in the field should not be deep, because the field will not be flat if it is deep, but it should not be shallow either. If the water is scarce, the soil will not be carried away. The depth and shal...

Problems solved by technology

[0004] However, in practical applications, the rear board of the existing paddy field leveling machine always has a certain angle with the paddy field leveling machine when it rises. When used in paddy fields, due to the existence of ridges, especially those with higher height Existence, there will always be some paddy fields that cannot be operated. At the corners and near the ridges, the slats will slip and cannot completely lift the soil, which brings great trouble and distress to people.

Simultaneously, because the assembly that connects the slats in the prior art is a circular tube, it is easy to bend and not firm when in use.
