Description

Feeding device of sorting machine

Technical Field

The invention relates to the field of sorting machines, in particular to a feeding device of a sorting machine.

Background

The sorting machine is widely used for grading and screening scattered materials, and can be generally divided into various forms such as a vibration sorting machine, a roller sorting machine, a relaxation sorting machine, a bar sorting machine, a vibration wind power composite sorting machine and the like according to the difference of the structure and the motion form of a sieve plate. When the separator works, materials fall into the sieve plate at a certain speed and an inclination angle, and are gradually dispersed, separated and screened through the movement of different forms of the sieve plate. The incident speed, angle and position of the material all affect the sorting effect and sorting efficiency of the sorting machine.

At present, the separator is widely applied in the fields of mine, building materials, metallurgy, machine-made sand and stone materials, building garbage, decoration garbage disposal and the like, and the feed of the separator is generally fed by a feeding device. However, the internal structures of the existing feeding devices are single flat plate structures with certain fixed inclination angles, and in engineering construction, once the feeding devices are installed and fixed, the inclination angles of the feeding devices are certain, so that in subsequent production and operation, under the condition that the front-end material flow working condition is stable, the incident angles of materials sliding to a sieve plate of a sorting machine through the feeding devices are relatively fixed, and the positions of the materials are relatively concentrated, so that the following problems are caused:

sorting efficiency is low:

the existing feeding device is generally manufactured according to the size of a material conveying belt, the difference between the width of the existing feeding device and the width of a sieve plate of a sorting machine is large, so that materials are difficult to uniformly disperse and tile on the sieve plate, and particularly, the materials are difficult to reach at the parts close to two sides of the front end of the sieve plate;

because the incident angle is relatively fixed, the blanking positions of the materials are relatively concentrated, so that the effective utilization area and the sorting efficiency of the sieve plate are reduced; meanwhile, when the types of materials are various and the components of the materials are complex, the fixed incident angle of the materials is maintained, and the materials with various types and components fall on the relatively concentrated position on the sieve plate, so that the expected separation effect is difficult to achieve;

the blanking positions are relatively concentrated, so that the effective utilization area of the sieve plate is reduced, the materials falling onto the sieve plate through the feeding device are concentrated near the blanking point and are difficult to reach the parts close to the two sides of the front end of the sieve plate, the materials are unevenly distributed on the sieve plate, the productivity of equipment is wasted, and the sorting efficiency is reduced;

an air inlet of the vibrating wind power composite sorting machine is positioned below the sieve plate, and an induced draft opening or an air outlet is positioned on one side of the end part of the feeding device, so that a wind field in a feeding box in the feeding device is disordered, even backflow wind and whirlwind are formed, light materials needing to be sorted by wind power cannot be effectively discharged from the induced draft opening or the air outlet, and the sorting efficiency is low;

secondly, the service life of the sieve plate is reduced:

because the distribution of the materials on the sieve plate is uneven and the blanking position is relatively concentrated, the concentrated impact and abrasion are easily caused to the local area of the sieve plate of the sorting machine, and the service life of the sieve plate is obviously shortened.
