[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the return belt cleaning device of one embodiment of the present invention includes a mounting frame 1, a support seat 2, a mounting plate 3 and an adjustment component 4. The mounting frame 1 is U-shaped, the support seat 2 is arranged inside the mounting frame 1, and the two mounting plates 3 are relatively arranged above the support seat 2 and are slidably connected to the support seat 2. The top of the mounting plate 3 is provided with a mounting hole 100 connected to the frame of the belt conveyor. The adjustment component 4 is arranged in the support seat 2 and connected to the mounting plate 3. The adjustment component 4 makes the two mounting plates 3 move closer to or away from each other.

[0027] The adjustment assembly 4 enables the two mounting plates 3 to move toward or away from each other on the support base 2, thereby adjusting the spacing between the two mounting plates 3 according to the width of the belt conveyor frame. This allows both mounting plates 3 to be stably connected to the frame through the mounting holes 100, securing the return belt cleaning device beneath the frame. Therefore, the return belt cleaning device of this embodiment is adaptable to belt conveyors of varying sizes.

[0028] As shown in Figure 4 The adjusting assembly 4 comprises a bidirectional screw rod 41 rotatably installed inside the support base 2, one end of the bidirectional screw rod 41 is fixedly connected with a knob 42, the outer surface of the bidirectional screw rod 41 is threadedly connected with two threaded hole plates 43, both of the threaded hole plates 43 are fixedly connected with sliding blocks 44, both of the sliding blocks 44 are slidably connected with the support base 2, and the sliding blocks 44 are fixedly connected with the mounting plates 3. The bidirectional screw rod 41 has two threads with different rotation directions, when the knob 42 is screwed, the bidirectional screw rod 41 rotates, so that the two threaded hole plates 43 move away from or close to each other, thereby driving the two mounting plates 3 to move away from or close to each other, the sliding blocks 44 are slidably connected with the support base 2, which plays a guiding role and makes the mounting plates 3 have high stability when moving.

[0029] As shown in Figures 1 to 3 Both sides of the two mounting plates 3 close to each other are provided with scraping assemblies 5. As shown in Figure 5 The scraping assembly 5 comprises a support plate 51, an elastic member 52, a connecting column 53 and a scraping plate 54, one side of the support plate 51 is connected with the mounting plate 3, the support plate 51 is provided with a blind hole 200 for installing the elastic member 52, the connecting column 53 is inserted into the blind hole 200 and connected with one end of the elastic member 52, and the scraping plate 54 is arranged at the end of the connecting column 53 away from the elastic member 52. By arranging the elastic member 52, when the device is installed on the rack, the scraping plate 54 can tightly abut against the belt, so that the subsequent manual adjustment process of the belt is saved, and when stubborn slag is encountered, the scraping plate 54 can automatically retract to avoid damage to itself and the belt. The scraping assemblies 5 on the two mounting plates 3 are staggered, when the two mounting plates 3 move close to each other, the scraping assemblies 5 on the two mounting plates 3 will not interfere with each other in structure, ensuring that the mounting plates 3 can move smoothly.

[0030] The top of the scraping plate 54 is in the shape of a triangular prism, which can better fit the belt and produce a large pressure on the belt to ensure good scraping effect of the slag.

[0031] Further, two blind holes 200 are formed in the support plate 51. At least two blind holes 200 are formed to arrange two elastic members 52 and two connecting columns 53, so as to provide stable and reliable elastic support for the scraping plate 54.

[0032] As shown in Figure 1 and Figure 2 The top of the mounting rack 1 is provided with an elastic pad 6. When the return belt cleaning device is installed in place, the top of the elastic pad 6 will contact the belt, which plays a certain sealing and dust reduction effect, reducing the pollution to the environment during belt cleaning.

[0033] Furthermore, the top of the elastic pad 6 is not higher than the top of the scraper plate 54 , thereby ensuring that the scraper plate 54 can press against the belt and ensure the cleaning effect of the scraping component 5 .

[0034] like Figure 1 and Figure 2 As shown, a water pump 7 is provided on one side of the mounting frame 1. A water spray pipe 8 is provided at the drainage end of the water pump 7, and the water spray pipe 8 faces the belt. The water spray pipe 8 can spray water onto the belt, thereby softening the material residue on the belt to a certain extent, making it easier for the scraper 54 to scrape the material residue off and reducing the dust generated during the scraping.

[0035] like Figure 2 and Figure 3 As shown, the two mounting plates 3 are fixedly connected to each other on one side thereof, and the two mounting plates 9 are staggered up and down. A discharge trough 300 is provided on one side of the support base 2, and a discharge barrel 10 corresponding to the discharge trough 300 is fixedly connected to the bottom surface of the support base 2. When the belt passes through a plurality of scraper plates 54, the scraper plates 54 can scrape off the slag on the belt. The scraped slag and sewage will flow into the discharge trough 300 through the mounting plates 9, and then enter the discharge barrel 10 from the discharge trough 300, and finally fall to the designated position, thereby collecting the slag and sewage and reducing environmental pollution. The two mounting plates 9 are staggered up and down, which, on the one hand, prevents the slag and sewage from contaminating the support base 2, and on the other hand, prevents the two mounting plates 9 from structural interference when the mounting plates 3 move relative to each other.

[0036] Furthermore, the flow plate 9 is tilted, with the side of the flow plate 9 close to the discharge trough 300 lower than the side of the flow plate 9 away from the discharge trough 300, so that the scraped residue and sewage can only flow into the discharge trough 300 and the discharge barrel 10.

[0037] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
