Description

Technical Field

[0001] The utility model belongs to the field of straw recycling, in particular to a corn straw recycling and crushing device. Background Art

[0002] Corn stover refers to the stems and leaves of corn plants, which are left after the corn crop is harvested. These stovers are usually yellow or golden in color, slender in shape, and fibrous in texture. They are usually regarded as an agricultural waste. Straw recycling is an environmentally friendly agricultural practice that aims to make full use of farm straw to reduce resource waste, reduce environmental pollution, and create economic opportunities.

[0003] According to application number 202220655878.9, a straw recycling and pulverizing device is disclosed, which relates to the technical field of straw recycling. In order to solve the problem that the existing straw pulverizer often has incomplete pulverization during pulverization, a lower supporting bracket is arranged at the upper end of the supporting platform, a pulverizing bin is arranged at the upper end of the lower supporting bracket, two pulverizing knife sticks are arranged inside the pulverizing bin, and the knife teeth of the two pulverizing knife sticks correspond to each other in an interlaced manner, a bracket slot is arranged on the inner wall of the lower supporting bracket, a plug-in plate is installed inside the bracket slot, a material receiving groove is arranged inside the plug-in plate, a discharging screen is arranged inside the material receiving groove, a recycling box is arranged below the plug-in plate, a suspension platform is arranged on the outer wall of one side of the lower supporting bracket, a lower knife groove is arranged inside the suspension platform, a straw cutter is arranged inside the lower knife groove, a cutting gantry is arranged outside the straw cutter, and a cutting scale is arranged on the outer wall of the cutting gantry;

[0004] This comparative case has effectively solved the problem that the existing straw crushers often have incomplete crushing during crushing, resulting in low straw utilization rate. However, since the crushed straw is screened by the discharge screen, and the screen is in a static state, after the crushed straw falls to the top of the screen, it is easy to accumulate on the top of the screen, which not only makes it impossible to screen the straw, but also affects the collection of the straw.
