Agricultural machinery straw crushing device based on water-washing silt removal technology

Abstract

The invention discloses an agricultural machinery straw crushing device based on a water-washing silt removal technology. The agricultural machinery straw crushing device comprises a cleaning box, a crushing box and a separating box, wherein the top end of the cleaning box is embedded with the crushing box; the bottom end of the crushing box is provided with a communicating hole; the center of thetop end surface of the crushing box is provided with a first motor; the inner cavity of the crushing box is provided with a crushing shaft; the bottom end of the crushing shaft penetrates through thecommunicating hole and is fixedly connected with a stirring rod through a connecting sleeve; the right side end of the cleaning box is fixedly connected with the separating box; the bottom part of the inner cavity of the separating box is provided with a separating net which separates the inner cavity of the separating box into a discharge chamber and a drainage chamber; and the interior of the discharge chamber is provided with a rotating shaft which is sleeved by an auger. According to the invention, through embedding of the crushing box on the cleaning box, two processes of crushing and cleaning are integrated together, and convenience in processing is greatly improved, so non-processing time is reduced, and processing efficiency is improved; and water stirred in the cleaning box is utilized to completely clean silts in crushed straw, and cleanness of straw can be effectively guaranteed, so the difficulty of subsequent processing is reduced, and the quality of processing is improved.

Description

technical field [0001] The invention relates to the field of straw crushing machinery, in particular to an agricultural machinery straw crushing device based on water washing and sand removal technology. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after the seeds are harvested. 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. [0003] Agriculture has bee...
