Abstract

The present grading sieve has the defects that the purpose is single, the structure is bulky, and the present grading sieve can not adapt to separation of various products. Because different products has different requirements to the mesh size of a sieve plate, the vibration frequency of a straining box, the slope angle of vibration amplitude, etc., and the intensity of air current, etc. The present grading sieve is too difficult to meet various requirements one by one; the aim of the utility model is to provide a device which can conveniently change the parameters, in order to meet the classification sieving requirement of granularity products, such as peanuts, corns, beans, etc., meet the classification sieving requirement of large grainy products and small particle products, such as paddy, wheat, millet, etc., and meet the classification sieving requirement of products with different granularity and different specific weights.

Description

Multi-purpose sorting sieve

Use classifying screen more, belong to the device that in industrial and agricultural production, product is carried out sizing screening by granularity and proportion.

Existing classifying screen or purposes are single or structure is heavy, can not adapt to sorting to multi-assortment production, because different product, to the screen deck net hole size, intensity of screen box vibration frequency and amplitude inclination angle etc. and air-flow etc. all has different requirements, existing classifying screen is difficult to satisfy one by one the requirement that these have nothing in common with each other.

The purpose of this utility model is to provide a kind of device that can carry out conversion easily to above-mentioned parameter, to adapt to the requirement of various pelletized products being carried out sizing screening.

The utility model is mainly by frame, screen box, vibrational system, air flow system, drive system constitutes, screen box is fixed on the frame by spring suspension device, and screen box tilt adjustable, be fitted with the multi-deck screen plate in the screen box, the mesh of these sieve plates begins from the upper strata that lower floor is more little more, and each sieve plate all can be extracted out from screen box at any time and change, the screen box bottom is fixed with vibrational system and fan, vibrational system is made of adjustable centrifugal of disk and the degree of eccentricity, fan is coaxial with disk, drive by elastic driving band by buncher, regulate the motor speed and the eccentric block degree of eccentricity, can adjust screen box vibration frequency and amplitude, regulate the joint air door of fan, can adjust current rate, and because air-flow is blown into from the screen box bottom, the top is sent, and helps the cleaning removal of impurities of product, help the conveying of product in screen box, the sieve plate mesh also is difficult for stopping up.Suitably select above these parameters and change suitable sieve plate, can adapt to the sizing screening of different grain size different specific weight product in little granule product such as big granule product such as peanut in the crops, corn, beans and paddy, wheat, millet and the industry.

Below in conjunction with embodiment and accompanying drawing thereof, be described in further detail the utility model.

Accompanying drawing 1: the utility model overall pattern;

Accompanying drawing 2: the utility model vibrational system and fan structure figure.

Screen box 1 is fixed on the frame 3 by spring suspension device 2, multilayer sieve plate 4 can insert from screen box 1 rear portion or extract out, there is the discharging opening 5 and the sediment flushing outlet 6 of each layer the screen box front portion, feeding mouth 7 and dust-precipitator 8 are arranged at its top, flow control board 9 is arranged in the feeding mouth 7, and the forward mounting part 10 of screen box can have been used elongated hole and Luo bolt along frame 3 adjusting that is shifted up and down in this example, if regulate not too frequent, this simple in structure, cost is low.The screen box bottom is fixed with coaxial mounted vibrational system and fan, its axle 11 is fixed on screen box 1 bottom by bearing block 12, vibrational system is made up of disk 13 and centrifugal 14, two centrifugal 14 coaxial being installed on the disk 13, and can radially regulate, two centrifugal 14 usefulness spring held, two centrifugal subtended angles increases of raising along with rotating speed, the degree of eccentricity reduces, automatically regulate amplitude and can suppress resonance, the wind-force of fan can be regulated by the joint air door 15 of import department, and buncher 16 is installed on the frame, by flexible conveyor belt 17 power is passed to vibrational system and fan.

Claims

1, uses classifying screen more, mainly form, it is characterized in that the screen box tilt adjustable, the removable sieve plate of multilayer is arranged in the screen box, be fixed with vibrational system and air flow system on the screen box by frame, screen box, vibrational system, air flow system, drive system.

2, according to claim 1 use classifying screen more, it is characterized in that the fan of the eccentric wheel of vibrational system and air flow system is coaxial.

3, according to claim 1 and 2 use classifying screen more, it is characterized in that having adopted in the vibrational system adjustable centrifugal of the degree of eccentricity.

4, according to claim 1ly many use classifying screen, it is characterized in that drive system adopts buncher, and with the transmission of elastic driving band realization power.
