Straw smashing and recovering device for agricultural machinery

Abstract

The invention relates to a straw smashing and recovering device for agricultural machinery. The straw smashing and recovering device comprises a cut-off chamber, a smashing chamber and an extrusion chamber. A cutting motor is fixedly arranged above the cut-off chamber, a cut-off rotating shaft is jointly arranged on front and rear walls of the cut-off chamber, cutting blades are arranged on the outer side of the cut-off rotating shaft, and the smashing chamber is positioned on the right side of the cut-off chamber. A rotating rod is arranged under a smashing motor which is fixedly arranged above the smashing chamber, a filter screen is arranged on the rotating rod, a plurality of suspension ropes are arranged around the upper end of the filter screen, and impact beads are connected to lower portions of the suspension ropes respectively. The extrusion chamber is arranged below the smashing chamber, discharging retaining plates are fixedly arranged on upper left and right sides of the extrusion chamber, and second extrusion rollers are arranged under first extrusion rollers which are arranged under the discharging retaining plates respectively. A collection motor is arranged at an outlet of the extrusion chamber and provided with a collection roller. The straw smashing and recovering device has advantages of structural simplicity, effectiveness in smashing and recovering and increase of economic benefits.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw crushing and recovery device for agricultural machinery. Background technique [0002] According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which becomes "waste" that is "not very useful" but must be disposed of; and crop straw is a very valuable biomass energy in the agricultural ecosystem. resources; the comprehensive utilization of crop straw resources is of great significance to promoting farmers’ income increase, environmental protection, resource conservation and sustainable development of agricultural economy; in addition to the traditional method of crushing straw and returning it to the field as organic fertilizer, it has also stepped out of straw feed, straw vaporization, straw New approaches such as power generation, straw ethanol, and straw building materials hav...

[0002] According to relevant statistics, my country, as a large agricultural country, can produce more than 700 million tons of straw every year, which becomes "waste" that is "not very useful" but must be disposed of; and crop straw is a very valuable biomass energy in the agricultural ecosystem. resources; the comprehensive utilization of crop straw resources is of great significance to promoting farmers’ income increase, environmental protection, resource conservation and sustainable development of agricultural economy; in addition to the traditional method of crushing straw and returning it to the field as organic fertilizer, it has also stepped out of straw feed, straw vaporization, straw New approaches such as power generation, straw ethanol, and straw building materials have greatly improved the utilization value and utilization rate of straw, which is worth learning from; promote the subsequent utilization of straw; support straw substitute wood, fiber raw materials, clean pulping, biomass energy, and commercial organic fertilizers The industrialization of new technologies such as the development of new technologies, the improvement of supporting industries and downstream product development, and the extension of the comprehensive utilization industry chain of straw; costs, reduces the economic benefits of farmers, and reduces farmers' enthusiasm for straw recycling; therefore, a straw crushing and recycling device for agricultural machinery is needed
