Description

Technical Field

[0001] The utility model relates to the technical field of stone mining, in particular to a mud powder screen for a quarry. Background Art

[0002] A quarry is a place dedicated to mining stones. It mainly extracts stones from underground or rocks for use in construction, road construction, concrete manufacturing, etc. During the quarrying process, screening equipment is needed to classify stones of different sizes.

[0003] According to a mud powder screen for quarries with application number 202320613991.5, this solution effectively solves the problem that during actual screening, water is needed to moisten rocks and the like during mining to facilitate drilling. At this time, the soil and dust on the bottom rocks will stick to the rocks, making it difficult to make these adhered soil and dust fall off during actual screening. At the same time, during screening, some smaller rocks will also stick to large rocks through the moist soil. These smaller rocks are easily removed during screening due to their small size, resulting in waste.

[0004] However, the following problems still exist in the operation of this solution:

[0005] (1) In the above scheme, only multiple screens can be used to screen the stones during operation. However, during the screening process, the stones are wet, which may cause the mesh of the screen to become clogged, and manual clearing is required, which affects the overall screening efficiency.

[0006] (2) During the screening process, when the amount that the screen can screen is lower than the discharge amount, blockage will occur during the discharge of stones and the problem of unmanageable blockage will occur. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The quarry uses a mud powder screen, and the small-aperture screen is lifted by the first cylinder. At the same time, the trigger rods inside the small-aperture screen and the medium-aperture screen are triggered, and then the medium-aperture screen is lifted by the small-aperture screen, and the large-aperture screen is lifted by the medium-aperture screen. In the process of lifting, the second connecting block on the surface of the second connecting column inside the mounting block on both sides of the small-aperture screen, the medium-aperture screen and the large-aperture screen rotates, and in the process of rotating, the connecting disc fixedly connected to the second connecting column on the side of the second connecting block squeezes the first spring, and at the same time, the first connecting block fixedly installed by the first connecting column on the side of the fixed housing rotates on the surface of the first connecting shaft, so that the small-aperture screen, the medium-aperture screen and the large-aperture screen are in an up and down swing state, so that the internal stones are quickly screened. In the whole operation, the screening speed is accelerated by the simulated shaking method to avoid the clogging of the screening mesh due to the wetting of the stone during the screening process, and then there is no need to manually clean the clogged mesh, and the overall screening efficiency is higher.

[0016] 2. The quarry uses a mud powder screen, and the second cylinder pushes the sealing plate. During the pushing process, the second spring on the top of the sealing plate is stretched, and during the stretching process, the sealing plate drives the damping rod to contract, so that the sealing plate and the conveying pipe are in a non-fitting state, and then the feeding shell enters the connecting shell.

The whole operation process can effectively achieve the effect of timed discharge, and thus in the process of discharge, it can avoid blockage caused by the discharge volume being greater than the processing volume and being unable to screen.
