Problems solved by technology

[0002] In the prior art, the well-known technology is the striking sleeves in use. At present, the striking sleeves used in the cantilever screen are all cylindrical barrel-shaped, and their outer surfaces are also smooth cylindrical surfaces. At the same time, the impact force received by each sieve is similar, so the vibration of each sieve is not very different, which is not good for removing the blockage between the two sieves, and cannot achieve the best anti-clogging effect. This is the shortcoming of existing technology

Embodiment Construction

[0012] In order to clearly illustrate the technical characteristics of the two schemes, the two schemes are described below through a specific implementation mode and in conjunction with the accompanying drawings.

[0013] The first technical solution:

[0014] by attaching figure 1 with 2 It can be seen that the impact sleeve for the cantilever screen of this program has a cylindrical barrel-shaped impact sleeve body 1. In this program, there is a spiral protrusion on the outer surface of the impact sleeve body 1, and the height of the spiral protrusion is 3-10mm, the pitch is 10-30mm. It is also possible to have a fixed helical spring 2 on the outer surface of the striking sleeve 1, the diameter of the helical spring 2 is 3-10 mm, preferably 6 mm, and the pitch is 10-30 mm. What this concrete examination mode adopts is to have fixed helical spring 2 on the outer surface of percussion cover body 1, and described helical spring 2 diameter is 6 millimeters, and pitch is 18 m...

Abstract

The invention provides two technical schemes of a beating sleeve for a cantilever screen. In the first scheme, the beating sleeve comprises a cylindrical barrel-shaped beating sleeve body, a spiral projected table is arranged on the outer surface of the beating sleeve body, or a fixed spiral spring is arranged on the outer surface of the beating sleeve body. In the second scheme, the beating sleeve body of the beating sleeve is a cylindrical spiral body. Through the two structures, the outer surface of the beating sleeve is changed into the unsmooth cylindrical surface with height variations, and the stress of two adjacent screen strips can be different when the cylindrical surface beats on the screen strips, so the two screen strips have different vibration and unequal amplitudes, materials blocked between the two screen strips are favorably removed, and the blocking prevention effect is improved.

Description

Technical field: [0001] The invention relates to a part in an industrial screening equipment, in particular to a striking sleeve for a cantilever screen Background technique: [0002] In the prior art, the well-known technology is the striking sleeves in use. At present, the striking sleeves used in the cantilever screen are all cylindrical barrel-shaped, and their outer surfaces are also smooth cylindrical surfaces. At the same time, the impact force received by each sieve is similar, so the vibration of each sieve is not very different, which is not good for removing the blockage between the two sieves, and cannot achieve the best anti-clogging effect. This is the weak point that existing technology exists. Invention content: [0003] The present invention aims at the deficiencies in the prior art, and provides a technical solution for a cantilever screen using a striking sleeve. It forms a non-smooth cylindrical surface with high and low changes. Such a cylindrical su...
