Material crushing and screening device

Abstract

The invention discloses a material crushing and screening device, which comprises two side plates, wherein the side plates are symmetrically arranged on a workbench; a cylinder cover is fixedly connected with the side plates; two ends of a roller movably sleeve the cylinder cover; the roller comprises a turnover plate and a screening mesh; an installation hole and a slideway are processed in each side plate; a baffle plate is fixed at the outer side of each slideway; a driving shaft is arranged in the installation hole and matched with a rolling bearing and a bearing cover plate; a driving gear is processed on the driving shaft; a slide block is located in each slideway; a driven shaft is arranged between the slide blocks and matched with a rolling bearing I and a bearing cover plate I; a driven gear is processed on the driven shaft; one end of an adjusting screw rod is fixed on each slide block and the other end extends out of the baffle plate and is screwed with an adjusting nut; a pressure spring also sleeves each adjusting screw rod; the roller rotates and passes through the turnover plate to continuously take materials to a high place for free falling; and the driving shafts drive the driven shaft to rotate, and the materials are ground into powder and screened through the screening mesh under the grinding action of meshed driving gears and driven gear, so that the material crushing and screening device is compact in structure, suitable for grinding of various materials and good in universality.

Description

technical field [0001] The invention relates to a material processing device, in particular to a material crushing and screening device. Background technique [0002] The crushing and processing of materials is often involved in daily life, such as the processing of flour, grinding corn kernels into corn flour, etc. Manual operation is labor-intensive and low-efficiency, and it is processed by special mechanical equipment. Since the raw materials targeted by each equipment are inconsistent , The equipment occupies a large area and other problems restrict the development of the processing workshop. How to design a general-purpose material crushing and screening device is of great significance to food processing enterprises. [0003] A material crushing and screening device mentioned in the present invention solves the above problems. Contents of the invention [0004] In view of the deficiencies in the above problems, the present invention provides a material crushing and ...
