Description

Technical Field

[0001] The utility model relates to the field of material recovery, in particular to a coal slime feeding and recovery system for a belt conveyor. Background Art

[0002] Underground transportation of coal and stone mainly relies on belt conveyors. During the transfer process, due to the water content of underground coal and stone, it is easy to have situations such as coal slime and crushed coal sticking to the belt. The direct loss of materials will occur if this part of the solid materials is not recovered, and coal accumulation will also occur in individual areas. In particular, the coal dust sticking to the belt will cause adverse operating conditions such as increased load of the belt conveyor and belt deviation. The simple belt conveyor scraper will also cause increased dust. In view of the above situation, there is currently a lack of corresponding solution equipment. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a coal slime feeding and recovery system for a belt conveyor that scrapes and cleans the lower belt and directly reuploads the falling material onto the belt.

[0004] The equipment includes a scraper mechanism and a falling material retransmission mechanism;

[0005] The scraper mechanism includes a body shell, and a scraper is arranged inside the body shell;

[0006] The falling material retransmission mechanism includes a transmission shell sleeve, and the transmission shell sleeve includes a first transmission section and a second transmission section; the first transmission section is communicated with the chamber of the body shell, the second transmission section is arranged at the tail end of the first transmission section, the chambers of the first transmission section and the second transmission section are communicated, and feeding augers are respectively arranged inside the first transmission section and the second transmission section;

[0007] A material release pipe is arranged on the second transmission section. The material release pipe is arranged corresponding to the upper belt of the belt conveyor.

[0008] Further, the first transmission section is arranged horizontally, and the second transmission section is arranged perpendicular to the first transmission section.

[0009] The achieved effect is that the coal dust and falling material on the lower belt scraped by the scraper enter the first transmission section of the transmission shell sleeve through the body shell, are conveyed to the second connection section and rise through the internal auger, and the material is retransmitted onto the belt by the material release pipe.

[0010] The beneficial effects of the utility model are as follows: The utility model solves the problems of waste of falling coal during belt cleaning and serious dust in the prior art, realizes the upload after the falling coal is scraped, can automatically recover materials, and avoids dust during the recovery process. Moreover, the equipment has a simple structure, is convenient to maintain, and operates safely. Description of the Drawings

[0016] The realization, functional features and advantages of the purpose of the present utility model will be further described in conjunction with embodiments with reference to the accompanying drawings. Specific implementation mode

[0017] Refer to Figure 1 , Figure 2 , a coal slime falling and recycling system of a belt conveyor according to the present utility model includes a scraper mechanism 1 and a falling and returning conveyor mechanism;

[0018] The scraper mechanism 1 includes a body shell 14, and a scraper is arranged inside the body shell 14;

[0019] The falling and returning conveyor mechanism includes a conveyor housing sleeve, and the conveyor housing sleeve includes a first conveying section 21 and a second conveying section 22; the first conveying section 21 is communicated with the chamber of the body shell 14, the second conveying section 22 is arranged at the tail end of the first conveying section 21, the chambers of the first conveying section 21 and the second conveying section 22 are communicated, and feeding augers are respectively arranged inside the first conveying section 21 and the second conveying section 22;

[0020] A material release pipe 221 is arranged on the second conveying section 22. The material release pipe 221 corresponds to the upper belt of the belt conveyor.

[0021] Furthermore, the first conveying section 21 is arranged horizontally, and the second conveying section 22 is arranged perpendicular to the first conveying section 21.

[0022] The achieved effect is that the coal dust on the lower belt and the falling material scraped by the scraper enter the first conveying section 21 in the conveyor housing sleeve through the body shell 14, are conveyed to the second connection section and rise by the internal auger, and the material is retransmitted to the upper part of the belt by the material release pipe 221.

[0023] Further, a spraying mechanism is provided inside the machine body housing 14. The spraying mechanism is a nozzle arrayed at the upper part of the inner cavity of the machine body housing 14, and the nozzle is connected to an external water source.

[0024] The effect achieved thereby is to spray water on the lower belt during the process of scraping coal slime, with higher cleanliness.

[0025] Further, the scraper includes a coal slime scraper 12 and a water draining scraper 13;

[0026] The coal slime scraper 12 is a plurality of small scrapers arranged staggeredly, and the water draining scraper 13 is an integral scraper with a flat cutting edge; the coal slime scraper 12 and the water draining scraper 13 are arranged at intervals.

[0027] During use, the water draining scraper 13 is arranged in front of the coal slime scraper 12, where the front here refers to the direction of movement of the lower belt as the front.

[0028] The effects achieved thereby are that a plurality of coal slime scrapers 12 are convenient for flexible replacement and maintenance; the water draining scraper 13 further cleans the belt and scrapes off excess water.
