Double-roller staggered anti-sticking rotary tiller for vibration scraping of rice stubble fields

Abstract

The invention discloses a double-roller staggered anti-sticking rotary tiller for vibration scraping of rice stubble fields. The double-roller staggered anti-sticking rotary tiller for vibration scraping of rice stubble fields comprises a whole rack, a knife roller assembly and a scraping device, wherein the knife roller assembly is a staggered knife roller assembly, and the staggered knife rollerassembly includes two knife roller assembly bodies; each knife roller assembly body includes a knife shaft, four orthogonal knife holders are fixed on the cross section of each knife shaft, and the knife holders on every two adjacent cross sections are arranged in a spiral shape; a rotary blade is fixed on each knife holder, the two knife shafts of the two knife roller assembly bodies are arranged in parallel and at the same height, and the rotary blades on the two knife shafts are staggered; and a gap is formed between two tips of every two staggered rotary blades. A double-knife-roller rotary blade staggered structure is adopted, and the axial distance between every two adjacent rotary blades of one same knife roller can be increased on the premise of ensuring the quality of rotary tillage, so that flow of rice straw and soil in the knife rollers is increased, accumulation of the rice straw and soil on the knife shafts, and soil adhesion and rice straw entanglement are reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of tillage in agricultural machinery, and specifically refers to a double-roller staggered anti-winding and sticking rotary tiller for vibrating and scraping rice stubble fields. Background technique [0002] The agricultural area in the middle and lower reaches of the Yangtze River adopts the rotary tillage method to directly bury and return the rice straw in the rice stubble field, which has the advantages of reducing the operation process, saving costs, and improving soil fertility. Due to the heavy soil and high water content of the rice stubble field, the high stubble and large amount of straw left after rice harvesting lead to a serious problem of rice stubble sticking to the soil in rotary tillage operations. Therefore, it is a development trend to study rotary tillage anti-tangle and anti-sticking technology in the agricultural areas of the middle and lower reaches of the Yangtze River. The followin...
