Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a straw throwing and returning machine with a crushing effect. Background Art

[0002] At present, the treatment of crop straw mostly adopts the method of straw crushing and returning to the field. Straw crushing and returning to the field not only avoids the environmental pollution problems caused by burning straw, but also can increase soil organic matter, improve soil structure, make the soil loose, increase porosity, reduce capacity, and promote microbial activity and the development of crop roots.

[0003] According to Chinese patent application number "CN213127129U," a dual-shaft spreading and returning machine suitable for large-scale farm operations comprises a base plate with universal wheels mounted at each of its four corners. A crushing box is mounted on the top of the base plate via a fixed frame, and two symmetrically distributed crushing mechanisms are disposed within the crushing box along its length. The crushing mechanisms comprise a rotating shaft, each end of which is connected to the inner walls of the crushing box via bearings. Spiral blades are fixed to the rotating shaft, and equidistantly distributed crushing blades are fixed to the outer wall of the rotating shaft via fastening bolts. During use, straw is fed from a feed hopper into the feed box. The first and second guide rollers rotate and squeeze the loose straw into shape, while simultaneously carrying it downward into small pieces cut by a cutter and dropping them into the crushing box. The pieces are then rapidly crushed within the crushing box, and the resulting straw debris falls through a large-aperture mesh plate into a spreading pipe and is then scattered out, completing the straw return to the field.

[0004] The above device filters the crushed straw through a mesh plate so that the straw that meets the size can fall down. However, the mesh plate is in a static state and is very likely to cause blockage, affecting the efficiency of returning the straw to the field. Therefore, a straw spreading and returning machine with a crushing effect is proposed to solve the above problems. Utility Model Content
