Problems solved by technology

[0002] The existing straw returning machines mainly crush the straw and lay it on the ground surface, or bury it shallowly on the ground surface. This mode will lead to too many large gaps on the soil surface, resulting in poor passability for subsequent sowing operations,

Abstract

The invention discloses a pulverizing, shred kneading, screw compressing and compacting straw returning machine which comprises a shell, a picking and chopping device installed on the shell, a spiralconveying device installed at the position, behind the picking and chopping device, of the shell and used for conveying materials chopped by the picking and chopping device, a shred kneading and thinning device arranged on the upper side of the shell and communicated with the spiral conveying device, a screw compressing device arranged at the position, under a shred kneading box body, of the shell, communicated with the shred kneading box body and provided with a discharge pipe at the tail end, a deep loosening and deep burying device hinged to the rear side of the shell, connected with the discharge pipe of the screw compressing device and used for deeply burying the materials, a first driving mechanism for driving the picking and chopping device, the spiral conveying device and the screwcompressing device to work at the same time, and a second driving mechanism for driving a driving shred kneading roller and a driven shred kneading roller to work at the same time.

Description

technical field [0001] The present invention relates to the field of agricultural engineering, and more specifically, the present invention relates to a machine for crushing, kneading, spirally compressing and densifying straw returning to the field. Background technique [0002] The existing straw returning machines mainly crush the straw and lay it on the ground surface, or bury it shallowly on the ground surface. This mode will lead to too many large gaps on the soil surface, resulting in poor passability for subsequent sowing operations, and the seeds cannot be separated from the soil. Good soil contact etc. issues. Moreover, after the straws distributed on the soil surface decayed, the organic matter mainly existed on the soil surface, and the effect on the organic matter content of the whole soil layer was not obvious. Therefore, on the basis of the existing straw returning machine, the present invention further pulverizes the crushed straw by kneading, densifying and...
