A gypsum rough grinding device

Abstract

The invention discloses a gypsum coarse grinding device. A driving shaft bearing is rotationally connected with a material storage box, and the right side of the driving shaft is fixedly connected with stirring teeth; the left side of the driving shaft is fixedly connected with two semi-conical gears, a bevel gear is arranged at the lower ends of the semi-conical gears, a bevel gear is meshed withthe tooth parts of the semi-conical gears, the bevel gear is fixedly connected with the upper end of the driven shaft, the lower bearing of the driven shaft is connected with the device body in a rotating mode, and the tooth parts of the semi-conical gears on the left and right sides are mutually staggered; and the lower end of the driven shaft is fixedly connected with a screw rod, and the screwrod is in threaded connection with a sleeve ring. The device drives a connecting rod to drive a bottom plate to make reciprocating opening and closing through a lantern ring so as to realize intermittent blanking, a crankshaft drives a push rod to push a movable plate to reciprocate left and right along a guide rail, left wedge-shaped plates are driven to move left and right, the wedge-shaped plates on the left side and the right side are used for grinding and crushing gypsum falling from the bottom plate, and the gypsum which is ground and crushed by the wedge-shaped plates is discharged from a discharging pipe. The device is reasonable and applicable in structural design, greatly improves the rough machining efficiency of the gypsum and saves labor force.

Description

technical field [0001] The invention relates to a gypsum processing machine, in particular to a gypsum rough grinding device. Background technique [0002] Gypsum is a monoclinic mineral, a hydrate whose main chemical composition is calcium sulfate. Gypsum is a versatile industrial and construction material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fireproof performance. [0003] Most of the gypsum raw materials need to be crushed before being reused during production. Most of the existing gypsum crushing and grinding devices add raw materials manually, which has a low degree of automation, low gypsum processing efficiency, and consumes a lot of labor.
