Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention, in particular to a material transfer dust prevention device. Background Art

[0002] After the ore is mined, the raw sand and gravel need to be transported. During the ore transportation process, the raw sand and gravel placed in the open are easy to fly under the influence of airflow, and the dust stirred up by the sand and gravel will be directly released into the air, resulting in a decrease in air quality; dust and debris may be scattered from both sides of the conveyor belt, causing pollution to the surrounding environment and increasing cleaning costs; at the same time, some fine sand and gravel particles may be blown away by the wind, causing material loss. The loss of materials directly affects the economic benefits of the enterprise and increases production costs.

[0003] Therefore, dust-proof devices are generally used to cover the materials. When a conventional canopy-type dust cover is used, the dust cover and the pallet containing the materials are in a simple covering state. At this time, the dust cover and the pallet are separated. During the movement of the transport vehicle, the dust cover, the pallet and the materials are prone to shaking and colliding with each other, affecting the service life of the dust cover. At the same time, the materials on the materials are also prone to tipping over under the impact, affecting the driving or material transportation safety. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a material transfer dustproof device to solve the problem that the dust cover, the tray and the material are prone to shaking and colliding with each other, thus affecting the service life of the dust cover.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a material transfer dust prevention device, including a cover body, and also including:

[0006] A fixing frame is connected to the lower end of the cover body, and a vertical side wall of the fixing frame close to one side of the cover body is horizontally provided with an embedding groove for embedding the edge of the tray.

[0007] The technical principle of the utility model is as follows: materials are placed on a pallet, and then a forklift is used to insert the pallet, and the forklift drives the pallet to be transferred to the cover body, and in the process of horizontally moving the pallet, the side edge of the pallet is aligned with the embedding groove of the fixing frame, and the edge of the pallet is limited by the embedding groove of the fixing frame, and then neatly and stably placed in the entire material transfer dust-proof device; during transportation, the embedding groove of the fixing frame can fully limit the edge of the pallet, so that the entire material transfer dust-proof device and the pallet maintain a stable matching relationship, the cover body is not easy to collide with the material and the pallet, and the service life of the cover body can be improved; the placement of materials on the pallet is also more stable, which improves safety during transportation.

[0008] Furthermore, the cover body includes an end cover and a telescopic cover with an "n"-shaped longitudinal section profile. The end cover is fixedly installed on the end of the telescopic cover, and the lower ends of the telescopic cover and the end cover are connected to the upper side of the fixing frame.

[0009] Through the above-mentioned arrangement, the telescopic cover can be in a folded state when the pallet is installed in conjunction with the fixed frame, so that the pallet can be placed horizontally at one end of the cover body close to the end cover, making the installation of the pallet and the material more convenient; after the pallet and the material are placed, the telescopic cover can be pulled out to cover the pallet and the material, making it easier to adjust the length of the telescopic cover according to the amount of the pallet and the material, and making it easier to store or unfold the material transfer dust-proof device.

[0010] Furthermore, the cross-sectional profile of the fixing frame is in an "n" shape, the middle portion of the fixing frame is fixedly connected to the lower end of the end cover, and both ends of the fixing frame are connected to the lower end of the telescopic cover.

[0011] Through the above arrangement, the fixing frame can be stably fixedly connected with the telescopic cover and the end cover, making the structure of the material transfer dust prevention device more stable.

[0012] Furthermore, the telescopic cover includes several layers of single-layer covers which are sequentially mounted from the inside to the outside, and several limit strips which are sequentially fixed and arranged in parallel are vertically fixedly installed on the upper sides of both ends of the fixed frame. The lower end of the single-layer cover is slidably arranged between two adjacent limit strips, and the outermost or innermost single-layer cover is fixedly connected to the end cover at one end close to the end cover.

[0013] Through the above arrangement, when several pallets are arranged and placed, the innermost or outermost single-layer cover is pulled horizontally to drive several single-layer covers in the middle layer to move synchronously along the limit strip, so that the telescopic cover can be stretched, making the telescopic cover convenient to stretch.

[0014] Furthermore, an elastic sealing strip which can abut against a side wall of an adjacent single-layer cover is provided on one end of the single-layer cover close to the end cover.

[0015] Through the above-mentioned arrangement, the elastic sealing strip can seal between two adjacent single-layer covers to prevent material from flying around and achieve a good dust-proof effect; at the same time, when the innermost or outermost single-layer cover is pulled horizontally, the elastic sealing strip that is against the side wall of the adjacent single-layer cover can drive the adjacent single-layer cover to move synchronously, making the telescopic control of the telescopic cover more convenient.

[0016] Furthermore, the length of the single-side limiting strip is 0.9-0.95 times the length of the end of the fixing frame.

[0017] Through the above arrangement, it is ensured that the length of the limiting strip is long enough to reduce the gap between the single-layer cover at the end of the material transfer dust prevention device and the end of the fixing frame.

[0018] Furthermore, the width of the embedding groove is 0.8-0.9 times the width of the fixing frame.

[0019] Through the above arrangement, the embedding groove is wide enough to ensure that the edge of the pallet can be accurately embedded in the fixing frame, making the matching installation between the pallet and the fixing frame simpler and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
