Differential speed stubble breaking type belt cleaning device

Abstract

The invention discloses a differential-speed stubble-breaking type seed belt cleaning device belonging to the field of agricultural machinery; wherein a vertical mounting frame is arranged in the axial center of the central axis of the mounting frame, and symmetrically arranged in sequence from the center of the central axis of the mounting frame to both ends. The shaft sleeve of the side mounting frame, the side mounting frame and the elastic retaining ring at the shaft end; the two ends of the central axis of the mounting frame are respectively connected with the rear ends of the two side mounting frames through bearings with seats; The two legs of the frame are respectively welded on the inner sides of the two side mounting frames, and the grain divider is installed on the upper cross plate of the casing mounting frame through the grain divider mounting frame and the middle part is also connected by bolts. The invention effectively cleans the sowing belt, improves the quality of no-tillage sowing, and increases the yield of crops; at the same time, the amount of disturbance to the soil is small, and the amount of soil movement is small, which can effectively reduce water and soil loss and improve soil moisture.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a differential speed stubble breaking type seed belt cleaning device. Background technique [0002] Conservation tillage has the characteristics of water storage and moisture retention, reducing runoff, water evaporation, wind erosion, water erosion, increasing soil organic matter, increasing soil aggregate structure, and improving fertility. Therefore, conservation tillage technology has been widely promoted and applied in my country in recent years. The key to implementing conservation tillage is to develop suitable and reliable supporting equipment, among which the no-tillage seeder is a key part. Since the no-tillage planter performs sowing operations on the ground covered with straw, it is necessary to install a certain straw cleaning device in front of the no-tillage planter, so as to provide a clean planting belt for subsequent planting operations. The seed...

AI Technical Summary

Problems solved by technology

The seed belt cleaning devices used in existing no-tillage seeders are mainly divided into two types: passive and active. Obtain a clean seeding belt, but the weight of the existing domestic no-tillage seeder is not enough to meet the requirements of cutting straws, especially for the one-ripening corn planting area in Northeast China, where the corn stalks are relatively thick and the amount of straw is large, and the overall seeding belt cleaning effect is not good good

The active seed belt cleaning device rotates at a high speed under the power drive, and the straw is fully cut, but there are problems such as deep penetration into the soil and large soil disturbance. In addition, the chopped straw is mixed with the soil, which affects the subsequent sowing operation.
