Folding suspended leveler for compound rotary cultivator special for paddy field

Abstract

The invention relates to a folding suspended leveler for a compound rotary cultivator special for a paddy field and belongs to the technical field of agricultural machinery. The folding suspended leveler consists of a field-leveling plate and a horizontal plate, wherein a horizontal plate mounting base is arranged in the middle of the field-leveling plate; a horizontal plate supporting plate and a connecting piece are symmetrically arranged on two sides of the field-leveling plate; harrow teeth are arranged on the field-leveling plate; and the horizontal plate consists of a main plate of the horizontal plate, extension plates, a rack, a semicircular gear, a hydraulic cylinder, a pin shaft and a pin shaft base, wherein the extension plate is arranged at two ends of the main plate of the horizontal plate through the pin shaft base and the pin shaft; and harrow teeth are arranged on bottom surfaces of the main plate of the horizontal plate and the extension plates. The leveler is provided with the horizontal plate which is movably arranged on the field-leveling plate, when a tractor is inclined to cause the leveler of the rotary cultivator to tilt to left and right sides, the horizontal plate can always keep a horizontal state, so the leveler can level the paddy field, remove slurry bank and guarantee the consistency for leveling the soil of the paddy field. The folding suspended leveler has the advantage of solving the problems of harrow missing and slurry bank phenomena of the conventional strong-pressure plate due to tilting and manual collection of the extension plates during work at headland.

Description

technical field [0001] The invention relates to a folding and suspending leveler of a special compound rotary cultivator for paddy fields, which belongs to the technical field of agricultural machinery. Background technique [0002] The special compound rotary tiller for paddy fields uses the rotary tiller on the knife-roller assembly to plow and break up the farmland soil, and then uses the strong pressure plate on the rear end frame of the knife-roller assembly to rake the farmland soil to complete the pre-planting of the farmland. preparations. Because the existing rotary tillers all rely on large and medium-sized tractors as the traction power, when the tractors are plowing in the field, due to their own weight too large and the softness of the farmland soil base, in addition to the reasons for mechanical operation technology, the tractors are not pulling. During the walking process, the siltation degree of the wheels on both sides in the soil is different, which make...

Problems solved by technology

Because the existing rotary tillers all rely on large and medium-sized tractors as the traction power, when the tractors are plowing in the field, due to their own weight too large and the softness of the farmland soil base, in addition to the reasons for mechanical operation technology, the tractors are not pulling. During the walking process, the siltation degree of the wheels on both sides in the soil is different, which makes the tractor body tilt, which drives the rotary tiller to tilt, resulting in uneven soil in the farmland after rotary tillage, and the strong pressure plate at the rear end of the rotary tiller. This will lead to the leakage of rakes or mud ridges in the farmland soil, which will affect the planting quality and crop yield of the farmland, and also increase the workload of post-management of the farmland
