Abstract
The utility model provides a double-layer raw coal roller screen, which is technically characterized by consisting of upper and lower layers of roller screen surfaces, wherein each of the upper and lower layers of roller screen surfaces consists of 8 to 30 parallel rollers at different intervals; screen plates are arranged on the rollers; the roller screen surfaces have an inclination angle along the motion direction of raw coal; a plurality of groups of screen plates are arranged on the rollers; distances among the screen plates are set according to the particle size; and each layer of rollers of the roller screen are driven by an independent speed reducer and an independent motor through a driving chain. The utility model has the advantages that: the roller screen has a simple structure and a reasonable layout, the capacity of matching the roller screen with a transporting system is improved, the efficiency of particle size classification is improved, and three materials with different level sizes are sieved.
Description
Technical field
The utility model relates to a kind of colliery and uses the coal classifying equipoment, particularly a kind of double-deck raw coal roller picker that is applicable to raw coal pre-classification and screening.
Background technology
Present raw coal roller picker is the individual layer roller picker, in use can only two groups of granularity ranks of classification, can not classification three groups granularity rank, to other requirement of particular level of granularity, it just can't satisfy in the actual production of colliery.Like patent announcement number is CN201632407U; Patent announcement number is CN201061787Y; Patent announcement number is 2123383U; Patent announcement number is CN201046435Y; Patent announcement number is CN201848384U; Patent announcement number is CN2451243Y; Patent announcement number is CN2936453Y; Patent announcement number is CN2030113U; Patent announcement number is CN2829914Y; Patent announcement number is CN200984552Y; Patent announcement number is CN101091950A; Patent announcement number is CN2361392Y, and the technology that these patents provided is the roller picker of individual layer compass screen surface.
Summary of the invention
The purpose of the utility model is to the deficiency that exists in the above-mentioned technology, and a kind of double-deck raw coal roller picker is provided, and not only compact conformation is reasonable, and screening efficiency is high.
The purpose of the utility model is to realize like this; Comprise reductor, motor, transmission bracket, screen box, driving-chain, screen tray axle and base; It is characterized in that reductor and fire-proof motor are fixed on the transmission bracket, fire-proof motor and reductor carry out transmission through belt.Driving-chain is connected with the sieve bobbin with reductor; And also connect through driving-chain between two sieve bobbins, screen box is fixed on the base, and two layer screen bobbin is up and down arranged in the screen box; And all becoming certain angle of inclination, the spacing that the sieve bobbin on upper strata is installed is greater than the spacing of lower screen bobbin.
Roller picker is made up of two-layer roller bearing compass screen surface up and down; Two-layer up and down roller bearing compass screen surface is made up of 8～30 different parallel roller bearings of spacing respectively; The screen tray that helps sieve that can make run of mine coal seam loosening is installed on the roller bearing, and the roller bearing compass screen surface has the angle of inclination along the raw coal direction of motion.The screen tray of installing on the roller bearing is the screen tray of many groups, sets the distance between screen tray according to granule size.The roller bearing compass screen surface is 3～8 ° along the angle of inclination of the raw coal direction of motion.Every layer of roller bearing of roller picker is respectively by independently reductor and motor come transmission through driving-chain.
The beneficial effect of the utility model is: the gap difference that the screen tray axle of levels is arranged can be sieved out the material of different stage; The sieve distance between axles on upper strata is bigger; Can sieve out than bulk materials; The relative upper strata of following interlamellar spacing reduces to sieve out less material, is conducted oneself with dignity and the effect of sieving the axle revolving force advances to fall discharge along sieve aperture less than the material in lower screen bobbin gap, and then sieves out the material of three kinds of ranks size.This invention simplifies the structure, and connection and reasonable arrangement has improved the ability to provide the auxiliary items with transportation system, has improved the efficient of partition size.
Description of drawings:
Fig. 1 is the structure chart of utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
The specific embodiment:
Can be known that by Fig. 1-3 is made up of reductor 1, fire-proof motor 2, transmission bracket 3, screen box 4, driving-chain 5, sieve bobbin 6 and base 7 parts, reductor 1 is fixed on the transmission bracket 3 with fire-proof motor 2, fire-proof motor 2 and reductor 1 carry out transmission through belt.Driving-chain 5 is connected with sieve bobbin 6 (1), 6 (2) with reductor 1; And also connect between the sieve bobbin 6 (1) and 6 (2) through driving-chain 5; Screen box 4 is fixed on the base 7; Two layer screen bobbin 6 (1) and 6 (2) is up and down arranged in the screen box 4, and all become certain angle of inclination, the spacing that the sieve bobbin 6 (1) on upper strata is installed is greater than the spacing of lower screen bobbin 6 (2).
Double-deck tilting roller picker job step: by motor-driven, the special-shaped screen tray that is serially connected in through the chain transmission on the parallel axes of several inclination certain angles is done constant speed rotation in the same way, forms the compass screen surface of two rollings.Material to be sieved travels forward under the rotary screen dribbling is moving; Granularity compass screen surface discharge greater than compass screen surface gap, upper strata from the upper strata; Discharge from lower floor's compass screen surface greater than the granularity in lower floor compass screen surface gap, fall discharge less than the granularity in lower floor compass screen surface gap from lower floor compass screen surface space, thereby accomplish the purpose of screening.
Claims (2)
1. double-deck raw coal roller picker; Comprise reductor, motor, transmission bracket, screen box, driving-chain, screen tray axle and base, it is characterized in that roller picker is made up of two-layer roller bearing compass screen surface up and down; Two-layer up and down roller bearing compass screen surface is made up of 8～30 different parallel roller bearings of spacing respectively; Screen tray is installed on the roller bearing, and the roller bearing compass screen surface has the angle of inclination along the raw coal direction of motion, and the screen tray of installing on the roller bearing is the screen tray of many groups; Set the distance between screen tray according to granule size, every layer of roller bearing of roller picker is respectively by independently reductor and motor come transmission through driving-chain.
