Description

TECHNICAL FIELD

[0001] The utility model relates to a belt conveyor technical field especially relates to a full sealing environmental protection belt conveyor. BACKGROUND

[0002] The belt conveyor is widely used in the material conveying of coal mine, sandstone, cement and other industries, and is a commonly used material conveying equipment. The conventional belt conveyor is usually exposed, and a large amount of dust is easily generated in the material conveying process. With the increasing requirement for environmental protection, more and more closed means are used to seal the belt conveyor to reduce and avoid the dust escaping in the conveying process.

[0003] In the prior art, the machine body of the belt conveyor generally adopts a truss structure instead of a single beam structure of DT II (A), the sealing on both sides is relatively complicated and the effect is not good, and the whole length is not sealed. Even if a dust cover is installed, the sealing is still not strict, so that dust is running and leaking, which is not conducive to environmental protection. In addition, the connection structure of the protective cover and the machine body in the prior art is unreasonable, and there are noise problems and rainwater will enter the internal system along the matching surface. For example, the utility model patent with publication number CN 219429229 U discloses a full sealing dust suppression belt conveyor, which only uses upper sealing plates and side sealing plates. In actual production, the sweeper cannot completely clean the adhered materials on the conveying surface of the belt, and there will always be residues. When the belt is in the return stroke, the adhered materials will fall off during the contact with the lower roller under the action of gravity. If not collected, it will pollute the site. In addition, the design of the sealing structure has high implementation and application cost.

[0004] In view of the above, the applicant proposes the full sealing environmental protection belt conveyor of the present application, which is optimized and improved from the machine body, dust cover, material guide groove, roller group and other aspects to improve the sealing effect.
