Raw material crushing device for rubber production

The invention discloses a raw material crushing device for rubber production. The raw material crushing device comprises a crushing box, a filtering plate and a stirring shaft, wherein the filtering plate and the stirring shaft are arranged in the crushing box; a material charge hopper is arranged above the crushing box; a stirring wheel is arranged in the crushing box and is positioned above a filtering plate; a first stirring gear is arranged at the surface of the stirring wheel; a stirring shaft is arranged under the filtering plate, and a second stirring gear is arranged at the surface ofthe stirring shaft; a material guide hopper is arranged under the stirring shaft; a stirring rod is arranged under the material guide hopper, and a third stirring gear is arranged on the stirring rod;a material discharge pipe is arranged at one side of the bottom end of the crushing box. The raw material crushing device has the advantages that by arranging a temperature adjusting device, the temperature in the crushing box can be adjusted according to the temperature requirement of rubber crushing, so that the rubber crushing effect is better, and the crushed rubber meets the requirements; byarranging multiple crushing devices, the rubber can be more thoroughly crushed; the structure is reasonable, and the operation is more convenient.
