Description

Technical Field

[0001] This utility model relates to the field of belt conveyors, and in particular to a dust prevention device for belt conveyors. Background Technology

[0002] Belt conveyors, widely used in mines, ports, factories, and other material handling applications, generate significant amounts of dust during operation. This dust not only pollutes the working environment but also affects the health of operators. Therefore, equipping belt conveyors with effective dust control devices is essential. Currently, the most common dust control device for belt conveyors is a fixed dust cover. This type of dust cover is typically installed on the conveyor frame using bolts, welding, or other fixing methods, isolating the conveyor belt and material transport area from the external environment to achieve dust prevention. However, this type of fixed dust cover has some significant shortcomings:

[0003] 1. Inconvenient to disassemble and assemble: Once a fixed dust cover is installed, it often takes a lot of time and manpower to disassemble or reinstall it.

[0004] 2. Impact on maintenance work: Due to the structural limitations of fixed dust covers, they hinder maintenance personnel from inspecting and repairing the internal components of the conveyor to a certain extent. When the conveyor malfunctions and it is necessary to inspect and repair critical components such as internal rollers, idlers, and drive units, the presence of fixed dust covers makes it difficult for maintenance personnel to quickly and easily access these components. Summary of the Invention

[0005] This utility model aims to address the shortcomings of existing technologies by providing a dustproof device for belt conveyors.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dustproof device for a belt conveyor, including a support installed on the outside of the end legs of the conveyor, a sliding rod clamped on the top of the support, a clamping seat for fixing the sliding rod detachably installed on the top of the support, a plurality of telescopic semi-dustproof covers slidingly mounted on the sliding rod, and the semi-dustproof covers rotating around the sliding rod, the tops of corresponding semi-dustproof covers on two sliding rods being magnetically fixed to form a complete cover, the contact surfaces of two adjacent plate dustproof covers on a sliding rod being magnetically fixed, a fixing frame being provided at the end of the conveyor housing, and the semi-dustproof covers located at the end of the conveyor being magnetically fixed to the fixing frame.

[0007] Specifically, the bottom of the clamping seat is equipped with a pressure block, and the clamping seat is fixed to the top of the support by bolts and the pressure block presses the slide rod.

[0008] Notably, the semi-dust cover is an accordion-style telescopic cover.

[0009] Specifically, the semi-dust cover has first mating plates on both sides, and the two first mating plates that come into contact are magnetically fixed together, and the first mating plates that come into contact are magnetically fixed together with the fixing frame.

[0010] Specifically, the top outer end of the semi-dust cover is provided with a second docking plate, and the two contacting second docking plates are magnetically fixed together.

[0011] Specifically, the bottom of the first docking plate is provided with a base plate, and the bottom of the base plate is provided with a sliding sleeve, which is fitted onto the sliding rod.

[0012] The beneficial effects of this utility model are:

[0013] This utility model, by setting up a support, sliding rod, and clamping seat, makes the entire dustproof device easy and quick to assemble and disassemble, and convenient to use.

[0014] This invention features a retractable semi-protective cover secured with magnetic attachment. When maintenance or inspection is required, personnel can easily compress the cover to quickly expose the area to be inspected, eliminating the need for cumbersome disassembly required by traditional fixed dust covers. This design significantly reduces preparation time, enhances convenience, and improves efficiency. Attached Figure Description

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1-2 As shown, a dustproof device for a belt conveyor includes a support 1 installed on the outside of the end legs of the conveyor. A sliding rod 2 is clamped on the top of the support 1. A clamping seat 3 for fixing the sliding rod 2 is detachably installed on the top of the support 1. A pressure block 6 is provided at the bottom of the clamping seat 3. The clamping seat 3 is fixed to the top of the support 1 by bolts and the sliding rod 2 is clamped by the pressure block 6. By setting the support 1, sliding rod 2, and clamping seat 3, the entire dustproof device is easy to assemble and disassemble, and convenient to use.

[0021] Several telescopic semi-dust covers 4 are slidably mounted on the slide rod 2, and the semi-dust covers 4 rotate around the slide rod 2. The tops of corresponding semi-dust covers 4 on two slide rods 2 are magnetically fixed to form a complete cover. The contact surfaces of two adjacent dust covers 4 on one slide rod 2 are magnetically fixed. A fixing frame 5 is provided at the end of the conveyor housing, and the semi-dust covers 4 located at the end of the conveyor are magnetically fixed to the fixing frame 5. The semi-dust covers 4 are accordion-style telescopic covers. First docking plates 7 are provided on both sides of the semi-dust covers 4. Two contacting first docking plates 7 are magnetically fixed. The contacting first docking plates 7 and the fixing frame 5 are magnetically fixed. A second docking plate 8 is provided at the top outer end of the semi-dust covers 4. Two contacting second docking plates 8 are magnetically fixed. A base plate 9 is provided at the bottom of the first docking plate 7. A sliding sleeve 10 is provided at the bottom of the base plate 9. The sliding sleeve 10 is fitted onto the slide rod 2.

[0022] When maintenance or inspection is required, maintenance personnel can easily compress the semi-dust cover 4 to quickly expose the area to be inspected, eliminating the need for cumbersome disassembly as with traditional fixed dust covers. This design significantly reduces preparation time before maintenance and improves efficiency. Furthermore, the semi-dust cover 4 can be rotated along the slide bar 2 to the ground, completely exposing the entire conveyor. This provides maintenance personnel with a more spacious and convenient operating area, making maintenance work more efficient and convenient, especially suitable for the repair and replacement of complex internal components of the conveyor.

[0023] The two semi-dust covers 4 on both sides, as well as the adjacent semi-dust covers 4 on the same side, are fixed by magnetic attraction. This connection method is simple, quick, and reliable. During maintenance, maintenance personnel can easily disassemble or reassemble the semi-dust covers 4 without using tools to remove bolts or perform welding operations, greatly improving the convenience of maintenance.

[0024] In operation, the first connecting plate 7 and the second connecting plate 8 are magnetically fixed, forming a complete dust cover 4. During normal operation, the semi-dust cover 4 tightly covers the conveyor belt and material conveying area, effectively preventing dust leakage. The magnetic fixing method ensures a tight connection between the semi-dust covers 4, further enhancing the dustproof effect, thereby reducing wear on conveyor components and improving equipment reliability and service life. Since maintenance does not require large-scale disassembly and reinstallation of the semi-dust cover 4, the risk of damage to the semi-dust cover 4 and conveyor components during maintenance is reduced. When the conveyor needs modification or upgrade, this adjustable dust cover design better meets new requirements. For example, when adjusting the conveyor length, only the semi-dust cover 4 needs to be extended or retracted accordingly, eliminating the need for large-scale replacement and installation like traditional fixed dust covers, reducing the cost and time of equipment modification.

[0025] The dustproof device of this utility model, through its unique telescopic dustproof cover design and magnetic fixing method, has significant beneficial effects in improving maintenance efficiency, enhancing maintenance convenience, reducing maintenance costs, and improving the quality of the working environment.
