A paddle board adjustment device for paddy field leveling machine

Abstract

The invention discloses a helical plate adjustment device for a paddy field leveling machine in the field of agricultural machinery, comprising a driving helical gear connected to a universal joint of a rotary tiller and a driven helical gear close to the helical gear, the driving helical gear and the driven helical gear A transition helical gear is meshed between the gears, and an "L"-shaped driven shaft is connected between the transition helical gear and the driven helical gear. The L-shaped driven shaft includes a vertical part and a transverse part, and the vertical part and the transition helical The middle part of the gear is connected, and the transverse part passes through the driven helical gear. When the rotary harrow is driven by the universal joint to turn, the universal joint transmits the steering torque to the driving helical gear. At this time, the driving helical gear starts to rotate, and the transitional helical gear meshing with the driving helical gear is stressed and surrounds the vertical part and The connecting point of the transverse part rotates, and the transitional helical gear in the rotation drives the driven helical gear to rotate, thereby completing the transmission of the steering torque. After adopting the technical proposal, the phenomenon of dragging and slipping when turning the board is improved, and the cultivated land area is expanded simultaneously.

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.
