Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and particularly relates to an anti-blocking mechanism for a stone vibrating screen. Background Art

[0002] The stone vibrating screen is an indispensable equipment in mines, quarries, construction aggregate production lines and other places. It is used to grade and screen the mined or crushed stones to obtain products with different particle sizes to meet downstream process requirements or market demands.

[0003] However, in actual operation, stone vibrating screens often face the problem of material blockage, which not only affects screening efficiency and reduces production capacity, but also causes increased equipment wear, increased energy consumption, and even causes equipment failure and shutdown, seriously affecting the continuity and economic benefits of the entire production process.

[0004] Therefore, when the vibrating screen is screening stones, in order to reduce the blockage of the screen by stones, protect the equipment and ensure the work quality, a stone vibrating screen anti-blocking mechanism is needed to solve the existing problem. Utility Model Content

[0005] In view of this, the utility model aims to provide a stone vibrating screen anti-blocking mechanism for the deficiencies in the prior art, which can protect the equipment and ensure the working quality in order to reduce the blockage of the screen by the stone when the vibrating screen is screening the stone.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stone vibrating screen anti-blocking mechanism, including a vibrating screen body, a screen is installed in the vibrating screen body, that is, the screen screen screens the stone, and a support plate located on the vibrating screen body is fixedly installed above the screen, the support plate is installed horizontally, and a plurality of clamping grooves are opened on the support plate, and a connecting belt is installed inside the clamping groove, and an elastic ball is installed on the connecting belt, that is, an elastic ball, and a plurality of elastic needles are arranged on the surface of the elastic ball, that is, the elastic ball vibrates the upper surface of the screen, and the elastic needles correspond to the corresponding sieve holes while the elastic ball bounces up and down, and a limiting component is also installed on the support plate, that is, the limiting component limits and fixes the connecting belt.

[0007] The limiting component comprises a limiting groove, in which a limiting block is installed, and the top of the limiting block is connected to a limiting plate, that is, the limiting plate drives the limiting block to be clamped in the clamping groove to limit the connection.

[0008] A handle is also installed on the top of the limit plate, and the handle is arranged to be symmetrically installed in two positions, that is, the handle is convenient for the staff to hold the limit assembly to limit the connecting belt.

[0009] The end of the screen is also connected to a first receiving plate, and a second receiving plate located on the vibrating screen body is also installed below the screen, that is, stones of different particle sizes fall from the first receiving plate and the second receiving plate respectively.

[0010] A vibration motor is also installed on the vibration screen body. The vibration motor is installed on the side wall of the vibration screen body, that is, the vibration motor drives the frame and the screen on the screen to vibrate.

[0011] The screen is installed on the vibrating screen body by bolts and is detachable, which makes it convenient for the staff to repair or replace the screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Firstly, when the vibration motor drives the screen and the vibrating screen body to vibrate, the elastic ball will move up and down due to the rubber material, and hit the middle part of the screen. Every time the elastic ball vibrates up and down, it will drive the elastic force to press the sieve holes on the screen, and knock the stones stuck in the sieve holes into the second receiving plate, so as to prevent the stones from being stuck on the screen and affecting the progress of the screening work.

[0014] Secondly, in the limiting assembly, the limiting block is driven by the limiting plate to be fixed inside the limiting groove by the connecting belt, so that the elastic balls are evenly distributed on the screen, avoiding the elastic balls from gathering together and reducing work efficiency.
