Problems solved by technology

The existing chute grid screen is welded by I-steel, which has poor structural strength and wear resistance. It is prone to deformation under the impact of ore for a long time and cannot effectively block large pieces of ore from entering the chute, which seriously affects production efficiency.
In addition, after the grid is damaged, in order to avoid affecting production, it must be repaired and replaced in time, resulting in an increase in cost, and it is difficult to repair after the slide grid screen is deformed, and sometimes it needs to be completely replaced, affecting production

Abstract

The invention discloses a grate of a draw shaft. The grate of the draw shaft comprises a grate frame, wherein a plurality of sieve holes are formed in the grate frame; the grate frame comprises a plurality of grate secondary pieces; and the grate secondary pieces are detachably assembled together through connecting pieces to form the grate frame. The grate of the draw shaft is high in integral structure strength and convenient to repair and change, and can be reused.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a grid screen for a chute. Background technique [0002] In mining, the ore is frequently transported. In order to improve the transport efficiency and save costs, it is usually necessary to set up a chute to dump the ore directly from top to bottom. The ore finally reaches the vibrating ore feeding machine through the exit of the chute. In order to prevent large ore from blocking the chute or causing impact damage to the vibrating ore drawer, a chute grate is usually installed at the mouth of the chute to prevent large ore from entering the chute. The existing chute grid screen is welded by I-steel, which has poor structural strength and wear resistance. It is prone to deformation under the impact of ore for a long time and cannot effectively block large pieces of ore from entering the chute, seriously affecting production efficiency. In addition, after the grid is damaged, in o...
