Rhombus trajectory moving compound sieve and sieving machine thereof

Abstract

The invention relates to a rhombus trajectory moving compound sieve. The sieve comprises a rack and a machine shell, the rack is provided with the machine shell, a feeding opening is formed in the upper portion of the machine shell, a first discharging opening is formed in the bottom of the machine shell, a rhombus vibration sieving unit is arranged in the machine shell, and comprises a first sieving plate set and a second sieving plate set, and the first sieving plate set and the second sieving plate set are arranged on the two sides of the inner wall of the machine shell. According to the rhombus trajectory moving compound sieve and the sieving machine thereof, particulate of river sand, food raw materials and the like can be effectively sorted and sieved according to the thickness, and the sieving machine has the beneficial effects of being high in sorting and sieving efficiency and small in labor intensity, and saving time and labor

Description

technical field [0001] The present invention relates to the technical field of screening equipment, and more specifically, relates to a compound sieve moving on a rhombic track and a screening machine thereof. The compound sieve and its screening machine are suitable for screening particulate matter such as construction sand and food raw materials. Background technique [0002] Existing sieving machines use multi-layer or multi-stage sieving devices to sieve the size of the particles. The sieving machine uses the relative movement between the bulk material and the sieve surface to allow some particles to pass through the sieve holes. Sand, gravel, gravel and other materials are divided into different levels of vibrating screening machinery and equipment according to particle size. During the sieving process, the particles in the material whose particle size is smaller than the sieve size pass through the sieve surface and fall under the sieve, which is called undersize. Pa...

AI Technical Summary

Problems solved by technology

Because the vibration frequency of the vibrating motor is too frequent, there is a disadvantage of low screening efficiency when screening materials with large particle size differences, and only a single separation can be performed, and the production efficiency is low; the existing screening equipment occupies an area of Large, complex structure, low manufacturing cost, extremely prone to failure, high maintenance cost, and long maintenance time
