Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor technology, specifically, it relates to a double-sided semi-open sliding dustproof device for conveyor belts. Background Technology

[0002] Dust covers for belt conveyors are sealed covers that prevent dust from flying and polluting the environment during the conveying of materials. They are installed on the belt conveyor frame and can protect the equipment from wind and rain while preventing dust from spreading and meeting environmental protection requirements.

[0003] When used for conveying materials on the ground, belt conveyors usually need to be equipped with dust covers. However, the structure of traditional conveyor belt dust covers is relatively fixed. If it is necessary to open the dust cover to inspect the conveyor belt inside, or if there is material spilled on the outside of the conveyor belt that needs to be cleaned, the dust covers on the sides must be removed one by one. Moreover, since the dust covers are relatively large, the process of dismantling and reassembling them becomes very cumbersome, which seriously affects work efficiency. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a conveyor belt double-sided semi-open sliding dustproof device.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A conveyor belt double-sided semi-open sliding dustproof device includes a fixed support frame, on which a fixed dustproof cover and a semi-sliding dustproof cover are provided. The fixed support frame includes two semi-circular arc support frames, one on the left and one on the right. The fixed dustproof cover is located on the inner side of the arc support frame, and the semi-sliding dustproof cover is located on the outer side of the arc support frame.

[0007] A first track and a second track are connected between the two arc-shaped support frames. There are two first tracks that are attached to each other and arranged side by side above the middle top of the arc-shaped support frame. There are also two second tracks that are respectively arranged on the outer bottom of both sides of the arc-shaped support frame.

[0008] The half-side sliding dust cover includes two half-side dust covers and two half-side dust cover brackets. The top and bottom of the half-side dust cover brackets are respectively mounted between the first track and the second track located on the same side via a rolling assembly. The half-side dust covers are correspondingly mounted on the half-side dust cover brackets located on the same side.

[0009] The lengths of the first track and the second track correspond and cover the notch portion of the fixed dust cover.

[0010] Furthermore, the half-side dust cover bracket includes a lower square steel at the bottom, an upper square steel at the top, and two sets of arc-shaped square steel.

[0011] Furthermore, the half-side dust cover is fixed to the half-side dust cover bracket by I-beams.

[0012] Furthermore, the rolling assembly includes pulleys that are restricted to rolling within the first and second tracks by engaging.

[0013] Furthermore, four sets of pulleys are provided within one of the rolling components.

[0014] Furthermore, the bottom of the fixed support frame is supported by a dust cover mounting bracket and a roller bracket.

[0015] Furthermore, a limiting hole is made on the second track.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The conveyor belt double-sided semi-open sliding dustproof device described in this utility model allows the semi-sliding dustproof cover to move along the first and second tracks via a rolling assembly. When maintenance or cleaning is not required, it can move to the gap in the fixed dustproof cover to cover and block dust. When maintenance or cleaning is needed, it can simply be moved to another position, thereby improving work efficiency and reducing conveying costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments.

[0028] like Figure 1-8 As shown, the conveyor belt double-sided semi-open sliding dustproof device of this utility model includes a dust cover mounting frame 8 as a base and an idler frame 10, on which a conveyor belt 14 is mounted. On the dust cover mounting frame 8, a fixed support frame 1 is provided, which includes two semi-circular arc-shaped support frames 11, one on the left and one on the right.

[0029] A fixed dust cover 9 and a half-sliding dust cover 2 are provided on the fixed support frame 1. The fixed dust cover 9 is located on the inner side of the arc-shaped support frame 11, and the half-sliding dust cover 2 is located on the outer side of the arc-shaped support frame 11. The fixed dust cover 9 has a gap, which allows workers to enter the inside of the conveyor belt for maintenance or cleaning.

[0030] Two arc-shaped support frames 11 are connected by a first track 12 and a second track 13. There are two first tracks 12 that are attached to each other and arranged in a row above the middle top of the arc-shaped support frame 11. There are also two second tracks 13 that are respectively arranged on the outer bottom of the two sides of the arc-shaped support frame 11.

[0031] The semi-sliding dust cover 2 includes two semi-dust covers 21 and two semi-dust cover supports 22. The top and bottom of the semi-dust cover supports 22 are respectively mounted between a first track 12 and a second track 13 located on the same side via a rolling assembly 4. The semi-dust covers 21 are correspondingly mounted on the semi-dust cover supports 22 located on the same side. The lengths of the first track 12 and the second track 13 are corresponding and cover the notch of the fixed dust cover 9. This allows the semi-sliding dust cover 2 to move along the first track 12 and the second track 13 via the rolling assembly 4. When maintenance or cleaning is not required, it can move to the notch of the fixed dust cover 9 to cover and block dust. When maintenance or cleaning is required, it can simply be moved to another position.

[0032] from Figure 7 It can also be seen that the fixed dust cover 9 can extend to the outside of the fixed support frame 1, and the half-side sliding dust cover 2 is the same. It is only necessary to extend the first track 12 and the second track 13 by the corresponding lengths.

[0033] The half-side dust cover bracket 22 includes a lower square steel 221 at the bottom, an upper square steel 222 at the top, and two sets of arc-shaped square steels 223. The half-side dust cover 21 is fixed to the half-side dust cover bracket 22, namely the lower square steel 221, the upper square steel 222, and the square steel 223, by I-beams.

[0034] The rolling assembly 4 includes pulleys 3 that are locked within the first track 12 and the second track 13 by engaging. Screws are also provided on the first track 12 and the second track 13 to enable movement. Furthermore, four sets of pulleys 3 are provided within one rolling assembly 4, which improves overall stability.

[0035] Several limiting holes 131 are also provided on the second track 13. The limiting holes 131 can limit the movement position of the half dust cover 21, and at the same time, can ensure that it will not easily move when covering the gap of the fixed dust cover 9. Specifically, it can be fixed between the limiting holes 131 by limiting pins 6, and the limiting pins 6 can be fixedly connected to the rolling component 4 by iron chain 5.

[0036] Dustproof plates 7 are also installed on top of the two first tracks 12 to further ensure the normal operation of the tracks.
