Gravel screening machine with adjustable feeding speed

Abstract

A sand and gravel screening machine with adjustable feeding speed, which relates to the field of sand and gravel processing, includes a screening cylinder placed laterally inclined, a fixing mechanism for fixing the screen, and the screening cylinder includes a The feeding mechanism, the screening net inside the cylinder and a plurality of material outlets, the screening net includes a first screening net and a second screening net, and the first screening net and the second screening net will screen the cylinder The interior is divided into three independent cavities, and each cavity is connected to a material outlet. The pores of the first sieve are larger than the pores of the second sieve; the first sieve and the second sieve The dredging device is respectively provided under the bottom of the casing; the feeding mechanism includes a casing, and a rotating shaft passing through the casing is arranged under the inside of the casing, and symmetrically arranged baffles are connected to the rotating shaft. The invention solves the problems of low efficiency of the existing screening machine, easy blockage of the screening net and inability to adjust the feeding speed of the feed port.

Description

technical field [0001] The invention relates to the field of sand and gravel processing, in particular to a sand and gravel screening machine with adjustable feeding speed. Background technique [0002] The sand and gravel screening machine can also be called the sand and gravel plane rotary screen. The square swinging screen is a new type of high-efficiency screening equipment. It is also called a reciprocating screen because of the motion track of the screen box when it is working; and because it is a high-precision screening equipment, some manufacturers also call it a precision screening machine or a square screen. Precision screening machine. The traditional gravel screening machine solves the problem that the output of the rotary vibrating screen is very small, the efficiency is not high, and it cannot meet the needs of modern industries; moreover, the screen of the screening machine is easily blocked by sand and gravel, which slows down the speed of sand and gravel l...
