A multi-stage crushing device for the production of deer antler powder

Abstract

The invention relates to a multistage smashing device for producing antler powder. The problems that existing antler powder is poor in smashing effect and is not thoroughly smashed are effectively solved. According to the technical scheme, the multistage smashing device comprises a box, a filtering screen is fixed to an opening in the lower end of the box, and a volume-variable frame composed of first vertical plates, second vertical plates and U-shaped plates is arranged on the upper surface of the filtering screen. A vertical rod is arranged over the frame, a pressing hammer is arranged at the lower end of the vertical rod, and a stirring rod capable of contracting towards the pressing hammer and resetting in the reverse direction is arranged below the pressing hammer. First ratchet wheel and pawl structures are arranged on the two sides of the vertical rod, the outer side of each U-shaped plate is rotationally connected with a reciprocating lead screw, when the vertical rod moves upwards, first pawls drive the first ratchet wheels on the same side to rotate, and therefore the rectangular frame is reset after the volume becomes large. A baffle is arranged at the lower end of thefiltering screen, when the vertical rod moves upwards, a rope drives the baffle to move backwards, and when the vertical rod moves downwards, the baffle is reset forwards. The multistage smashing device is novel in conception, ingenious in structure and high in practicality.

Description

technical field [0001] The invention relates to the field of velvet crushing equipment, in particular to a multistage crushing device for the production of velvet powder. Background technique [0002] In the production process of velvet powder, the velvet antler is first removed, the surface fluff is removed, and then washed, cut into sections and dried. The dried velvet strips are hard and brittle, and the interior of the velvet strips has a honeycomb structure. Can be crushed and ground. [0003] At present, velvet antler powder is mostly crushed by rotating blade agitating pulverizer or roller pressure roller pulverizer. Due to the hard and brittle characteristics of velvet antler strips after drying, these two pulverizers are hard and brittle during the pulverization process. Both have the disadvantages of poor crushing effect and large particle diameter after crushing, so further screening, filtering and grinding are required after crushing, which leads to long crushin...
