Agricultural straw smashing machine with secondary smashing structure

Abstract

The invention discloses an agricultural straw smashing machine with a secondary smashing structure in the technical field of smashing machines. A groove is formed in the end, away from a transmissionrod, of each fixing block. A secondary smashing barrel is arranged at the bottom of an extrusion chamber. The top of the secondary smashing barrel communicates with the extrusion chamber through a connecting opening. Arranged blades are inserted in grooves through insertion blocks, the insertion blocks are fixed in the grooves through threaded holes and fixing bolts, and therefore the insertion blocks can be demounted conveniently, and the blades are demounted independently for replacing and cleaning; and when straw is added into the a primary smashing barrel from adding openings, the rotatingstirring blades can be used for cutting the long straw section by section, and after-period extrusion is facilitated; and meanwhile, the extrusion chamber is arranged, the cut straw falls into the straw again, an electric telescopic rod pushes an extruding plate, the extruding plate is used for pushing the cut straw to the left side of an inner cavity of the extrusion chamber, the cut straw is extruded, and the secondary smashing barrel can smash the clumpy straw conveniently.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to an agricultural straw pulverizer with a secondary pulverization structure. Background technique [0002] Straw refers to the part of mature crop stems, leaves or ears, usually refers to the remaining part after harvesting seeds of wheat, rice, corn, potato, rape, cotton, sugarcane and other crops, and straw is rich in nitrogen and phosphorus , Potassium, Calcium, Magnesium and organic matter, etc., are a kind of renewable biological resources with many uses. Straw is also a kind of roughage, which can be eaten by cattle, sheep and other livestock. Although the device that can crush straw has been proposed in the prior art, When it is impossible to cut and crush the straw effectively and quickly, and the blades in the traditional shredder cannot be disassembled separately, and cannot be replaced and cleaned after long-term use; [0003] To this end, we propose an agricultural...
