Accurate dosing and feeding device used for anchoring and shotcreting work

Abstract

The invention discloses an accurate dosing and feeding device used for anchoring and shotcreting work. The device comprises a device body, a cavity is formed in the device body, the upper end of the cavity is communicated with the lower end of a transverse groove, the transverse groove is located in the upper end of the device body, two guiding plates are arranged on the left end of the transversegroove, two guiding plates are arranged on the right end of the transverse groove, the number of the guiding plates is four, one end of each guiding plate is fixedly connected to the top of the transverse groove, one side of the other end of each guiding plate is connected with one end of a guiding shaft through a first bearing, the middle of the outer side of each guiding shaft is sleeved with abelt pulley, the number of the belt pulleys is four, the two belt pulleys at the left end of the transverse groove are connected in a wound mode through a belt, and the two belt pulleys at the rightend of the transverse groove are connected in a wound mode through a belt. The belts drive containing grooves to move to achieve the feeding effect for the cavity; a user controls the feeding quantityaccording to a stirring progress, and therefore the mass of materials is increased; under the condition that no machines are additionally arranged, dosing and feeding are made matched each time, anddosing and feeding quantity is 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
