Abstract

The utility model provides multi-stage oscillating screen. A multilayer screen mesh with large inclination angles is arranged on a screen basket. A discharge groove is arranged on both sides of the lower surface of each layer screen mesh. A vibration transmission shaft is horizontally arranged on the center of gravity position of the screen basket. A couple of eccentric wheels are respectively arranged on both ends of the transmission shaft. The utility model has the advantages of simple structure, electricity saving, and high screening efficiency. The utility model is an ideal feed division machine for sand stone extraction, mining extraction and construction worksite.

Description

Multi-stage oscillating screen

The utility model relates to a kind of multi-stage oscillating screen that sandstone or ore are sieved out by different size specifications.

General vibratory sieve only is provided with one to the secondary screen net in the prior art, and they can only sieve the material of two to three kinds of size specifications simultaneously, and the multilayer vibratory sieve of existing design, generally all be to adopt at the per pass sieve to establish this method of vibrating motor, but this Structure of Vibrating Screen complexity, the cost height, power consumption is big.

It is a kind of simple in structure, light and handy that the purpose of this utility model is to provide, and power saving can be sieved the material of multiple size specification, the adjustable multi-stage oscillating screen of Oscillation Amplitude simultaneously.

The technical scheme that the utility model solves is: it comprises sieve basket, screen cloth, motor, transmission mechanism, support and compression spring, it is characterized in that on the sieve basket of vibratory sieve, being provided with the screen cloth of several layers high inclination-angle, both sides below every layer of screen cloth are provided with blow tank, vibration transmission shaft is located on the horizontal level of sieve basket center of gravity, and cross the sieve basket left and right sides, the two ends of power transmission shaft are loaded onto adjustable fixed eccentric of a pair of degree of eccentricity and variable eccentric respectively.

Advantage of the present utility model:

1. adopt multilayer basket rack and panel construction, material usage is few, from heavy and light.

2. vibration transmission shaft is installed on the sieve basket horizontal location of the center of gravity, can make shake power be distributed to the sieve basket to greatest extent, equably everywhere, material screening efficient height, power saving.

3. the eccentric degree of eccentricity reaches the purpose of adjusting the Oscillation Amplitude size on the power transmission shaft thereby can adjust as required.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Figure one is the structural representation of the utility model multi-stage oscillating screen.

Figure two is the partial structurtes schematic diagram of the utility model transmission mechanism.

Be welded into the sieve basket 1 of four layers of high inclination-angle with shaped steel, every layer of the sieve basket is welded with crossbeam 2, the more little steel wire in lower floor aperture is laid on respectively on every layer of basket frame screen cloth in order to begin more from the upper strata, four legs 3 of sieve basket have compression spring 4, and by the compression spring 4 be fixed on the pillar on ground, both sides below every layer of screen cloth are respectively equipped with blow tank 5, be convenient to material like this and in screening process, in time tumble heap, vibration transmission shaft 6 is contained on the sieve basket horizontal location of the center of gravity, and cross and sieve basket 1 left and right sides, fixed eccentric 7 and 9 is separately fixed at the two ends of power transmission shaft, variable eccentric 8 and 10 is fixed on fixed eccentric 7 and 9 by screw respectively, in addition, on each eccentric wheel, have stand-by screw respectively in advance, when needs are adjusted every pair of eccentric degree of eccentricity, can after they are aligned with each other screwhole position, fix with screw, also be provided with compression spring 12 under motor 11 supports, motor 11 is by V belt 13, belt pulley 14 is connected with power transmission shaft 6.

During use, actuating motor 11 power supplys, motor is passed to power transmission shaft 6 to power by V belt 13 and belt pulley 14, power transmission shaft 6 drives eccentric wheel and rotates together, owing to eccentric rotation produces centrifugal force, this centrifugal force makes power transmission shaft 6 drive whole sieve basket shake, and the material on each layer screen cloth bounces on screen cloth and rolls, wherein the less material of granularity is fallen down one deck screen cloth by mesh, and the material that granularity is bigger then tumbles on the stockpile by blow tank.

Claims

1. multi-stage oscillating screen, comprise sieve basket, screen cloth, motor, transmission mechanism, support and compression spring, it is characterized in that: the screen cloth of on sieve basket (1), establishing the several layers high inclination-angle, both sides below every layer of screen cloth are provided with blow tank (5), power transmission shaft in the vibrating mechanism (6) is located on the horizontal level of sieve basket (1) center of gravity, and cross sieve basket (1) left and right sides, the two ends of power transmission shaft (6) are loaded onto the adjustable fixed eccentric of a pair of degree of eccentricity (7) and (9) respectively, variable eccentric (8) and (10).
