Description

Sieve plate and beam structure of three-axis elliptical orbit vibrating screen

technical field

The utility model belongs to the field of vibrating screening machinery, and mainly relates to a sieve plate and a beam structure of a three-axis elliptical track vibrating screen. the

Background technique

In the prior art, the sieve plate of the vibrating screen is generally installed on the lower beam of the vibrating screen frame, and the sieve plate is fixed through the sieve plate mounting holes on the lower beam. Due to the need to drill holes on the lower beam, the strength of the lower beam is damaged, and the lower beam of the screen machine is also subject to the impact and wear of materials, which all affect the service life of the screen machine. Even if there is the lower beam guard plate, because it is integral, the replacement and installation of the guard plate are all inconvenient. In addition, in the existing three-axis elliptical track vibrating screen used for sintering, the sieve plate is very easy to loosen, and it is also very inconvenient to install and replace. the

Contents of the invention

The purpose of this utility model is to provide a sieve plate and beam structure of a three-axis elliptical track vibrating screen. The vibrating screen with this structure can effectively prevent the sieve plate from loosening, and at the same time effectively prevent the impact and wear of materials on the lower beam of the screen frame. . the

The utility model is achieved through the following measures. It is a three-axis elliptical track vibrating screen mainly composed of a screen frame, three vibrators, a screen plate and a vibration-reducing support device. Under the long hole of the seat, there is a two-way limit groove for T-shaped bolts; in the direction of the incoming flow of the lower beam of the screen frame, a guard plate seat is welded; one side of the L-shaped guard plate is located between the screen plate and the U-shaped support. Between them, the sieve plate and the L-shaped guard plate are fixed to the U-shaped support by T-shaped bolts; the other side of the L-shaped guard plate is fixed to the guard plate seat by countersunk screws; the surface of the L-shaped guard plate in contact with the material, Composite with non-metal wear-resistant layer. In order to make the sieve plate installed firmly and not loose, there is no non-metal wear-resistant layer on the part of the L-shaped guard plate in contact with the sieve plate. For the convenience of installation and disassembly, the L-shaped guard plate is composed of multiple sections along the length direction of the lower beam. The corners of the L-shaped guard plate are processed into obtuse angles or circular arcs. The non-metallic wear layer on the L-shaped guard is rubber or polyurethane. the

The beneficial effect of the utility model is that the sieve plate and the lower beam are fixed by the U-shaped support and the T-shaped bolt, and the installation is firm and not loose; the L-shaped guard plate installed in the direction of the material flow can effectively prevent the impact of the material on the lower beam And wear, the composite wear layer can improve the life of the guard plate. It has the characteristics of compact structure, firm installation and long service life, and is suitable for three-axis elliptical orbit vibrating screens and other screening equipment. the

Detailed ways

An embodiment of the present utility model is described below in conjunction with accompanying drawing. The three-axis elliptical trajectory vibrating screen is mainly composed of a screen frame, three vibrators, a screen plate and a vibration-reducing support device. On the top of the lower beam 8 of the screen frame, a U-shaped support 11 is welded, and under the long hole of the U-shaped support 11, a T-shaped bolt bidirectional limiting groove 10 is arranged (patent has been declared, patent application number 201020203970.9) ; In the direction of the incoming flow of the lower beam 8 of the screen frame, a guard plate seat 7 is welded; one side of the L-shaped guard plate 5 is located between the sieve plate 3 and the U-shaped support 11, and the sieve plate 3 and the U-shaped support 11 are connected by T-shaped bolts 9 The guard plate 5 is fixed to the U-shaped support 11; the other side of the L-shaped guard plate 5 is fixed to the guard plate seat 7 through the countersunk head screw 6; the surface of the L-shaped guard plate 5 in contact with the material is compounded with a rubber wear-resistant layer . In order to make the sieve plate 3 installed firmly and not loose, there is no rubber wear-resistant layer on the circular part that contacts the sieve plate 3 on the L-shaped guard plate 5 . Guard plate is made up of three sections along the length direction of lower beam 8. The corner of the L-shaped guard plate 5 is processed into an obtuse angle. the
