Abstract

A continuous multilayer oscillating screen comprises screens, a hopper and motors, and is characterized in that a front frame (2) and a rear frame (3) are arranged on a support (1) made of metal, springs (4) are arranged among layers, the hopper (5) is mounted on the upper portion of the rear frame, a discharging port (6) is arranged on the front lower side of the hopper, a coarse screen (7) is mounted on an upper layer, a middle screen (8) is mounted on a middle layer, a fine screen (9) is mounted on a lower screen, a stock supporting plate (12) is mounted below the front end of each screen, and the eccentric oscillating motors (15) are mounted below the stock supporting plate. The continuous multilayer oscillating screen solves the problems of time consuming and labor waste of an existing screen, and has the advantages of success by the aid of screening once without replacing the screens, time and labor economization, physical strength reduction of farmers, fast speed, fine effects, small investment cost, capability of being widely used for rural areas, mines and factories needing classified screening, and the like.

Description

Continuous multi-layer vibrating screen

technical field

The utility model relates to the field of agricultural machinery, in particular to a vibrating screen capable of classifying coarse, medium and fine particles at one go.

technical background

Every year, during the harvest season of rice, wheat, and beans in rural areas, the purchasing department implements price evaluation based on quality; therefore, when this type of grain enters the warehouse, farmers often use more manpower to screen the grain in order to ensure the quality, and one by one Heaping grain is not only sifted once, but also needs to be changed frequently for coarse and fine sieves, which is time-consuming and laborious. After a day in groups of two, they are often exhausted with sore arms, backaches, and dust and sweat all over their bodies. Although electric rolling sieves and vibrating sieves have been introduced into the world at present, the sieves still need to be replaced constantly, which is very inconvenient.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned deficiencies, and provide a vibrating screen that can be continuously screened by category once input.

The purpose of this utility model is achieved by the following technologies: a continuous multi-layer vibrating screen, which is composed of a sieve, a hopper, and a motor, is characterized in that: on a support made of metal, there is a front frame and a rear frame; Springs are installed between layers, a hopper is installed on the upper part of the rear frame, and there is a discharge port at the front and lower part of the hopper. The upper layer is equipped with a coarse screen, the middle layer is equipped with a middle screen, and the lower layer is equipped with a fine screen. There are baffles and side plates on both sides. There is a material bearing plate under the front end of each layer of sieve, which is inclined to the rear. There is a side plate on each side of the material bearing plate. The front end of the material bearing plate is the discharge port. An eccentric vibrating motor is installed under the material bearing plate.

The remarkable effect of the utility model: one-time screening is successful; no need to change the sieve, saving time and labor and reducing farmers' physical strength, fast speed and good effect, and can be widely used in rural areas, mines and factories that need to be sorted and screened, and the input cost is small.
