Converse speed-difference follow-up wedge-shaped shovel type apparatus for cleaning weeds and soil on disc surface

Abstract

The invention belongs to the technical field of agricultural machines, and especially relates to a converse speed-difference follow-up wedge-shaped shovel type apparatus for cleaning weeds and soil on a disc surface. A disc shaft is connected with a disc via a shaft sleeve, and the center position of the upper surface of the disc is provided with a gear box in which a gear shaft is installed; the disc shaft is sleeved by a large gear, the gear shaft is sleeved by a small gear, and the small gear is engaged with the large gear; and one end of the gear shaft penetrates the cover of the gear box, and is fixedly connected with one end of a Z type wedge-shaped shovel. When the apparatus works, the disc rotates and drives the disc shaft to rotate, the rotating disc shaft drives the wedge-shaped shovel to conversely rotate on the disc surface via the gear group and the gear shaft, thereby realizing the purpose of cleaning weeds and soil on the disc surface. The gear box installed on the disc surface is designed in a modularization manner, and the apparatus is simple in structure and convenient to mount and dismount, and can be directly installed on a conventional disc furrow opener.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a device for cleaning grass and soil on the surface of a wedge-shaped shovel disc with reverse differential speed. Background technique [0002] At present, no-till planters have been widely used in no-till and less-till land, and the opener, as its key component, directly affects the quality of sowing and the efficiency of the machine. When there are many weeds and high soil viscosity, there are many weeds and soil on the surface of the opener, which will affect the normal operation of the opener to a certain extent, thus affecting the quality of sowing. . The existing soil and grass cleaning devices mainly install scrapers on the guard plate of the opener, and the scraper close to the surface of the disc can remove the soil when the disc rotates, but this increases the working resistance of the opener at the same time. , and it is easy to cause clods and weeds ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of the existing discs such as poor surface cleaning and grass cleaning effects, large soil disturbance, and large working resistance of the opener, the present invention provides a reverse differential speed follower wedge-shaped shovel type disc surface cleaning, The soil device can rotate with the disc on the surface of the disc opener to clean up the weeds and soil on the surface of the disc
