Accurate dosing and feeding device used for anchoring and shotcreting work

Abstract

The invention discloses a precision distributing device for anchor shotcrete operation, which comprises a device body, a cavity is arranged in the device body, the upper end of the cavity communicates with the lower end of a transverse groove, and the transverse groove is located at the bottom of the device body. In the upper end, two guide plates are provided at the left and right ends of the transverse groove, and the number of guide plates is four. One end of the four guide plates is fixedly connected to the top of the transverse groove, and one side of the other end of the four guide plates Both are connected to one end of the guide shaft through the first bearing, and the outer middle part of the guide shaft is sleeved with a belt pulley. The number of pulleys is four. The two pulleys at the left end of the transverse groove are connected by belt winding, and the transverse groove The two belt pulleys on the right end are also connected by belt winding. The belt drives the placement groove to move, and realizes the feeding effect on the cavity. The user controls the amount of feeding according to the mixing progress, which improves the quality of the material without increasing the machine. Next, make each batching and feeding match, and the batching and feeding amount are accurate.

Description

Technical field [0001] The present invention relates to the related technical field of mines, in particular to a precise material distribution device used for anchor spraying operations. Background technique [0002] Bolting and shotcreting are engineering measures that use bolts and shotcrete to support the surrounding rock. The role of bolts is to enhance the friction between the joint surface and the rock formation and enhance the stability of the rock block or rock formation. The function of shotcrete is to reinforce the surrounding rock and prevent it from lifting, peeling or falling. The two combine to exert the self-supporting capacity of the surrounding rock. [0003] Due to the wide application of bolt-and-spray technology in mine production, the bulk materials such as yellow sand and cement transported from mine trucks to underground are increasing year by year, but these materials must be mixed evenly according to a certain ratio before they can be used, so there is disc...

AI Technical Summary

Problems solved by technology

[0005] 1. In the prior art, there is no good equipment for the batching process. The traditional manual batching prolongs the construction process and reduces the construction progress;

[0006] 2. There is no good feeding device in the prior art. Generally, all the materials are directly placed in the mixer. This mixed method makes the quality of the produced materials poor and cannot meet the use standards of the materials;

[0007] 3. If the machine is used to automatically feed the material, the cost of the equipment will be greatly increased, and the ingredients of the machine cannot match the feeding material
