Description

Technical Field

[0001] The utility model relates to the technical field of stacker-reclaimer hoppers, and more specifically, to a stacker-reclaimer hopper with a dustproof function. Background Art

[0002] A stacker-reclaimer is a large-scale material handling equipment, widely used in mines, ports, power plants, building materials and other industries. It is mainly used for stacking and retrieving bulk materials. It can realize efficient, large-scale and automated material handling, improve operating efficiency and reduce labor intensity. The stacker-reclaimer hopper is an intermediate device connecting the conveying system and the stacker-reclaimer. The hopper can temporarily store materials transported from the conveyor belt to provide a buffer for subsequent stacking or retrieving operations.

[0003] Publication No. CN220536507U provides a new type of stacker-reclaimer hopper. In view of the fact that during the operation of the existing stacker-reclaimer, materials are transported by a ground belt conveyor and are obliquely thrown into the hopper located at the head of the tail car by the belt conveyor roller at a certain initial velocity. However, since the materials have a certain speed, the upper hopper body will be seriously worn. The interior of the hopper is covered with wear-resistant blocks, which improves the wear resistance of the hopper. At the same time, the wear-resistant blocks are fixed to the hopper by countersunk bolts for easy replacement, and are divided into several blocks. Only the damaged wear-resistant blocks need to be replaced, and there is no need to replace the entire block, which saves costs. In addition, vibration plates are added on the left and right sides of the hopper. The servo motor changes the direction to drive the ball nut to move up and down to achieve up and down vibration of the vibration plate, thereby achieving shaking unloading of the material and avoiding hopper blockage.

[0004] When the stacker-reclaimer hopper is in use, there is no dust cover above the hopper. During the stacker-reclaimer operation, dust in the material is likely to diffuse into the air in large quantities, affecting the surrounding environment and the health of the workers.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting up a mobile dust-proof mechanism and a dust-sucking mechanism, a protective effect is played by a mobile dust-proof plate and a fixed plate to prevent a large amount of dust from spreading into the air from above the stacker-reclaimer hopper. By adjusting the opening distance between the mobile dust-proof plate and the stacker-reclaimer hopper, the minimum size of the feed and discharge ports is ensured to be maintained during the stacking and reclaiming process to avoid unnecessary dust diffusion. Dust suction is performed at the feed and reclaiming port to further improve the dust-proof effect. Compared with the prior art, the mobile dust-proof plate and the fixed plate are used to prevent the dust generated during work from spreading outward. At the same time, the opening size of the mobile dust-proof plate and the stacker-reclaimer hopper is adjusted according to the specific conditions of the work stacking and reclaiming to ensure that the opening is not too large during work, further preventing dust diffusion. At the same time, dust suction is performed at the stacker-reclaiming port to achieve a better dust-proof effect, preventing dust from spreading to the surrounding air and affecting the air quality, and preventing the health of the staff from being affected by inhaling a large amount of dust;

[0016] 2. The limit slider slides inside the limit slide groove, and the connecting slide rod slides inside the through slide groove, which plays a limiting role to prevent the movable dust plate and the threaded sleeve from rotating with the fixed groove, ensuring that the movable dust plate moves in the horizontal direction. At the same time, the dust collected in the dust box falls back into the hopper of the stacker and reclaimer by opening the electromagnetic valve. At the same time, the dust is also material debris and powder, etc., which can avoid material waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle of the utility model: During the use of the stacker and reclaimer hopper with dust-proof function provided by the utility model, the dust-proof effect is firstly achieved through the movable dust-proof plate 2 and the fixed plate 3 on the top of the stacker and reclaimer hopper 1, so as to prevent dust from being diffused into the air from the top of the stacker and reclaimer hopper 1 in large quantities when stacking and reclaiming materials. At the same time, when the opening size between the movable dust-proof plate 2 and the stacker and reclaimer hopper 1 is adjusted according to the demand of the specific stacking amount, the motor 4 is started, so that the motor 4 drives the threaded rod 6 at its output end to rotate, and at the same time, due to the threaded connection between the threaded rod 6 and the threaded sleeve 7, the threaded sleeve 7 is driven to move, so that the connecting slide rod 9 slides inside the through slide groove 8. The limiting slider 11 slides inside the limiting slide groove 10, thereby driving the movable dustproof plate 2 to move, thereby adjusting the opening size between the movable dustproof plate 2 and the stacker hopper 1 to avoid dust diffusion to the greatest extent. At the same time, when stacking and retrieving materials, it is carried out through the opening between the movable dustproof plate 2 and the stacker hopper 1. The dust at the opening is removed by starting the exhaust fan 16, so that the exhaust pipe 15 draws out the air in the dust collecting box 14, and then the dust passes through the exhaust hood 12 and the connecting pipe 13 into the dust collecting box 14. The dust is isolated by the filter 17, so that the dust remains in the dust collecting box 14, and the air is discharged through the exhaust fan 16, further avoiding dust diffusion.
