A Straw Harvesting, Crushing and Returning Machine

Abstract

The invention discloses a straw harvesting, crushing and returning machine, which comprises a reel, a cutting assembly, a feeding assembly, a conveying assembly, a crushing assembly, a grass discharge assembly, a transmission mechanism and a frame. The whole machine of the present invention adopts a frame structure and a detachable combined mechanism, has multiple functions, low energy consumption and high operating efficiency. It can realize multiple functions such as large-scale stubble harvesting, straw harvesting, crushing, and returning to the field. One operation can complete multiple operations such as straw picking, stubble cutting, crushing, spreading or collecting and storing at the same time, which can save operating time and reduce operating costs, and can meet the requirements of large-scale operations in the field.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a straw harvesting, crushing and returning machine. Background technique [0002] With the rapid development of my country's rural economy and agricultural mechanization, the effective utilization rate of crop straws such as rice, wheat and corn has dropped sharply, and a large amount of straws have been discarded or burned, resulting in serious waste and pollution of resources. Measures and approaches for effective and rational utilization of straw. Crop straw crushing and returning to the field is beneficial to increase the organic matter and nutrient content of the soil, improve the physical properties of the soil, increase the biological activity of the soil, and have a significant effect on increasing yield. Therefore, the development and utilization of straw has become the main way to solve the utilization of crop straw, and has become a new focus of the deve...

Patent CN203353212U discloses a large-scale straw crushing and returning machine. This utility model straw crushing and returning machine has a better straw crushing effect, but this machine can only realize the crushing of straw, and cannot realize the harvesting of high stubble straw of the combine harvester and the Recycling of crushed straw

Patent CN1O3688677A discloses a straw crushing and returning machine. The straw crushing and returning machine crushes the straw through a high-speed rotating arc cutter, and the crushed straw is returned to the field on the spot, which solves the problem of the crushing blade of the existing straw crushing and returning machine. (Swinging knife) is perpendicular to the ground. For the problem that the upright straw on the ground cannot be crushed and returned to the field, but this machine does not have the functions of straw collection and stubble harvesting, which brings about low efficiency of straw crushing and easy entanglement of the crushing knife. Grass, which cannot meet the needs of large-scale operations in the field
