Stubble-cleaning soil-crushing rotary tillage apparatus

Abstract

The invention provides a stubble-cleaning soil-crushing rotary tillage apparatus. A handle unit A, a handle unit C, a handle unit E, a handle unit B, a handle unit D and a handle unit F are successively uniformly arranged at the outer periphery of a cutter shaft along a spiral direction. The handle unit A is successively provided with a right stubble-cleaning knife, a right soil-crushing knife and a right rotary tillage knife from the left to the right; the handle unit C is successively provided with a right rotary tillage knife, a right stubble-cleaning knife and a right soil-crushing knife from the left to the right; the handle unit E is successively provided with a right soil-crushing knife, a right rotary tillage knife and a right stubble-cleaning knife from the left to the right; the handle unit B is successively provided with a left stubble-cleaning knife, a left soil-crushing knife and a left rotary tillage knife from the left to the right; the handle unit D is successively provided with a left rotary tillage knife, a left stubble-cleaning knife and a left soil-crushing knife from the left to the right; and the handle unit F is successively provided with a left soil-crushing knife, a left rotary tillage knife and a left stubble-cleaning knife from the left to the right. The apparatus provided by the invention can simultaneously realize stubble-cleaning, soil-crushing and rotary tillage functions, and is simple in overall structure, small in land occupation and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a stubble and soil rotary tiller. Background technique [0002] The farmland rotary tillers currently used in our country usually only have the functions of rotary tillage and soil crushing. The device and the crushing device are simply combined on one machine, and each mechanism is relatively independent. In addition, in order to increase the stubble removal function, an independent stubble removal mechanism will be set on this type of machinery. This relatively independent setting method not only makes the structure of the agricultural machinery very complicated, but also increases the floor space of the machinery, so that it is very inconvenient to operate such a large-scale machinery in the farmland. Simultaneously, it is easy to generate interference among relatively independently arranged mechanisms, which reduces the stability of the implement. Contents ...

Problems solved by technology

This relatively independent setting method not only makes the structure of the agricultural machinery very complicated, but also increases the floor space of the machinery, so it is very inconvenient to operate such a large machinery in the farmland

At the same time, interference is likely to occur between relatively independent mechanisms, which reduces the stability of the machine tool
