Straw smashing device of cotton stalk pulling pulverizer

Abstract

The invention discloses a straw smashing device of a cotton stalk pulling pulverizer. The front of a rack is internally provided with an auger conveying drum, wherein a double-drum clamping extrusionconveying mechanism is arranged in the middle, on the rear part of the auger conveying drum, of the rack horizontally in an up-down mode, the conveying mechanism comprises a lower clamping roller, anupper clamping roller, a bearing seat, a sliding bearing seat, an adjusting bolt and a tensioning spring, and rectangular convex edges are uniformly arranged on the axial roller surfaces of the upperclamping roller and lower clamping roller; a cutting knife smashing mechanism is arranged in the rear of the rack, and comprises a rotating drum, cutting knives, fixing bolts and cutting knife brackets; the cutting knife brackets are uniformly distributed on the peripheral surface of the rotating drum at intervals, the top face of each cutting knife bracket is high in the front and low in the rear, and the cutting knives are obliquely arranged on the cutting knife brackets through the fixing bolts; a throwing mechanism is arranged above the cutting knife smashing mechanism, and comprises a rotary throwing plate and a throwing port. The device has the advantages that the smashing capacity is strong, and cotton stalks can be finely smashed and return to the field.

Description

Technical field [0001] The invention relates to a straw crushing device of a cotton pulling rod crusher. Background technique [0002] The scale of cotton planting in my country has been increasing year by year in recent years. It has become the world's largest cotton producer and consumer, and its total output and unit yield rank first in the world. The process of recycling cotton straw is an important part of the agricultural production process. Recycling straw after harvest is beneficial to increase soil fertility, reduce the amount of chemical fertilizer, improve the structure of the soil to increase crop production, and reduce environmental pollution caused by burning straw; [0003] Cotton stalk has a high crude fiber content and has the conditions to be used as animal feed after production and processing, which can ensure the comprehensive utilization of cotton stalks in a large area and realize the efficient use of resources. At the same time, cheap straw feed can save the b...

Problems solved by technology

[0005] The straw pulverizing device of the existing cotton stalk pulverizer grinds the straw unevenly and incompletely, and can only coarsely pulverize the cotton straw. The thickness and size of the pulverized straw are different. On the one hand, it is not conducive to The stalks are decomposed and returned to the field. On the other hand, it is not conducive to throwing the crushed stalks out during recycling. At the same time, blockages are prone to occur during the crushing process, resulting in low crushing efficiency and affecting normal work quality and efficiency.
