Straw smashing and returning device for agricultural planting

Abstract

The invention discloses a straw smashing and returning device for agricultural planting. The straw smashing and returning device comprises a base plate, a smashing chamber is fixedly installed in the middle of the top of the base plate, a smashing motor is fixedly installed in the smashing chamber through a support installed on the left side of the smashing chamber, a smashing shaft is fixedly installed on an output shaft of the smashing motor, one side of the smashing shaft penetrates through the left side of the smashing chamber and extends into the smashing chamber, the surface of the side, located in the smashing chamber, of the smashing shaft is sleeved with a smashing roller, smashing blades are fixedly installed on the outer surface of the smashing roller, and a discharging bin is fixedly installed in the middle of the bottom of the smashing chamber. According to the straw smashing and returning device for agricultural planting, through cooperative use of a first rotating motor, a cam plate, an extrusion plate, a reset spring, a push rod, a feeding port, a pretreatment chamber, a tool apron, a sectioning tool and a cutting plate, straw entering from the feeding port is subjected to sectioning treatment, so that the whole straw is cut into small sections, therefore, a subsequent smashing mechanism can conveniently smash the straws, the smashing effect of the smashing mechanism on the straws is greatly improved, the smashing effect is good, and the improvement of the straw fertilization effect is facilitated.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a straw crushing and returning device for agricultural planting. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. However, the current traditional straw crushing and changing field device, wh...
