Abstract
A three-shaft elliptical track vibrating screen plate and beam structure belongs to the vibrating screening mechanical field. A three-shaft elliptical track vibrating screen which is mainly composed of a screen frame, three vibration exciters, a screen plate and a vibration damping supporting device is characterized in that a U-shaped support is welded on each screen frame lower beam. A T-shaped bolt bidirectional limit slot is equipped on the lower part of the U-shaped support long-strip hole. A protective plate seat is welded on the screen frame lower beam part facing the material flow. One side of an L-shaped protective plate is located between the screen plate and the U-shaped support. The screen plate and the L-shaped protective plate are fixed on the U-shaped support through a T-shaped bolt. The other side of the L-shaped protective plate is fixed on the protective plate seat through a countersunk rivet. A non-metal wear resistant layer is compounded on one L-shaped protective plate surface which is in contact with the materials. The three-shaft elliptical track vibrating screen plate and beam structure which has the characteristics of compact structure, firm screen plate installation and prolonged lower beam service life is suitable for a three-shaft elliptical track vibrating screen and other screening devices.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to the sieve plate and the beam structure of three-axis elliptic track vibratory sieve.
Background technology
The sieve plate of vibratory sieve generally is mounted on the sill of vibratory sieve screen frame in the prior art, by the sieve plate installing hole on the sill sieve plate is fixed.Owing to need on sill, hole, so that the intensity of sill is damaged, the sill of screen(ing) machine also will be subjected to the impact wear of material, these all influence the service life of screen(ing) machine.Even the sill backplate is arranged, owing to be whole, the replacing of backplate and installation are all inconvenient.The three-axis elliptic track vibratory sieve that existing in addition sintering deposit is used, sieve plate is very easily loosening, and installation and replacing are also very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of sieve plate and beam structure of three-axis elliptic track vibratory sieve, and this structural vibrations sieve can prevent effectively that sieve plate is loosening, has also prevented the impact wear of material to the screen frame sill simultaneously effectively.
The utility model is realized by following measure.Main by screen frame, three three-axis elliptic track vibratory sieves that vibrator, sieve plate and vibration damping support device are formed, it is characterized in that: on the screen frame sill, be welded with the U-shaped bearing, below the strip hole of U-shaped bearing, be provided with the bidirectionally limited groove of tommyhead bolt; The screen frame sill meet the materials flow direction, be welded with plate support; One side of L shaped backplate is fixed to sieve plate and L shaped backplate on the U-shaped bearing by tommyhead bolt between sieve plate and U-shaped bearing; The another side of L shaped backplate is fixed on the plate support by sunk screw; The surface that L shaped backplate contacts with material is compounded with nonmetal wearing layer.For sieve plate is installed firmly, not loosening, the position that contacts with sieve plate on L shaped backplate does not have nonmetal wearing layer.In order to mount and dismount conveniently, L shaped backplate is made up of multistage along the length direction of sill.Obtuse angle or circular arc are processed in the corner of L shaped backplate.Nonmetal wearing layer on the L shaped backplate is rubber or polyurethane.
The beneficial effects of the utility model are that sieve plate and sill are fixed by U-shaped bearing and tommyhead bolt, install firmly, do not become flexible; Meet the L shaped backplate that the materials flow direction is installed, can effectively prevent impact and the wearing and tearing of material to sill, compound wearing layer can improve the life-span of backplate.Have compact conformation, install firmly and the characteristics of long service life, be applicable to three-axis elliptic track vibratory sieve and other screening plant.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the A-A cutaway view of Fig. 2, the i.e. structural representation of sieve plate and crossbeam.1 is screen frame, the 2nd among the figure, vibrator, the 3rd, sieve plate, the 4th, vibration damping support device, the 5th, L shaped backplate, the 6th, sunk screw, the 7th, plate support, the 8th, sill, the 9th, tommyhead bolt, the 10th, the bidirectionally limited groove of tommyhead bolt, the 11st, U-shaped bearing.
The specific embodiment
Below in conjunction with a description of drawings embodiment of the present utility model.Three-axis elliptic track vibratory sieve mainly is made up of screen frame, three vibrators, sieve plate and vibration damping support devices.On screen frame sill 8, be welded with U-shaped bearing 11, below the strip hole of U-shaped bearing 11, be provided with the bidirectionally limited groove 10 of tommyhead bolt (having declared patent, number of patent application 201020203970.9); Screen frame sill 8 meet the materials flow direction, be welded with plate support 7; One side of L shaped backplate 5 is fixed to sieve plate 3 and backplate 5 on the U-shaped bearing 11 by tommyhead bolt 9 between sieve plate 3 and U-shaped bearing 11; The another side of L shaped backplate 5 is fixed on the plate support 7 by sunk screw 6; The surface that L shaped backplate 5 contacts with material is compounded with the rubber wear-resisting layer.For sieve plate 3 is installed firmly, not loosening, the circular position that contacts with sieve plate 3 on L shaped backplate 5 does not have the rubber wear-resisting layer.Backplate is formed by three sections along the length direction of sill 8.Obtuse angle shape is processed in the corner of L shaped backplate 5.
