[0040] The guide trough body 2 includes an expanded arc-shaped upper cover plate 206 arranged on the top of the guide trough body 2, two side plates 202 fixedly connected to the lifting frame 14 through the connecting flange 201, and a wear-resistant side plate 205 is welded on the inner side of the side plate 202. A roller assembly is arranged below the guide trough body 2, and a conveyor belt 203 is arranged above the roller assembly. A double-layer overflow prevention skirt plate 204 is arranged between the wear-resistant side plate 205 and the conveyor belt 203, which is arranged in conjunction with the wear-resistant side plate 205, and the sealing and dustproof effect is better. The overflow skirt plate 204 is made of a composite of highly wear-resistant polyurethane and natural rubber. When the double-layer overflow-proof skirt plate 204 is installed, the skirt edge is fixed with angle aluminum and clamped by a clamp. A secondary skirt edge is provided on the skirt edge. After the installation position is determined, it is pulled outward to be in close contact with the conveyor belt 203 to play a secondary sealing role. The length of the skirt edge is the same as the length of the guide trough. The round head of the angle aluminum is inserted into the triangular opening of the clamp. The T-bolt is connected with the C-shaped piece welded on the side plate. The handle on the T-bolt is rotated to achieve clamping.

[0041] The roller assembly includes a roller support 16 arranged below the guide trough body 2, a plurality of rollers 17 are arranged on the top of the roller support 16, bottom support plates 18 are arranged on both sides of the rollers 17, and a high molecular polyethylene plate 19 is arranged on the top of the bottom support plate 18, a transparent acrylic plate 20 is arranged on the top of the bottom support plate 18 through a clamping piece, and the clamping piece is an L-shaped buckle arranged on the inner side of the bottom support plate 18, and a clamping piece is arranged on the side plate 202, and the transparent acrylic plate 20 can be installed by aligning the seams;

[0043] Embodiment 3

[0044] In conjunction with Example 1 and Example 2, please refer to Figure 1 , Figure 4 and Fig.11 As shown, the specific improvements are as follows: a dust curtain installation box 21 is fixedly arranged on the top of the guide trough body 2, and multiple dust curtain installation boxes 21 are arranged at the overflow and outlet of the guide trough. A cover plate 22 is arranged on the top of the dust curtain installation box 21, and a limit rod 23 is fixedly connected to the bottom of the cover plate 22. A limit hole adapted to the limit rod 23 is opened on the top of the dust curtain installation box 21. The limit rod 23 is used to limit the cover plate 22. A dust curtain 24 is arranged at the bottom of the cover plate 22. The dust curtain 24 has no less than 5 layers and is made of wear-resistant, flame-retardant and antistatic rubber material, which is soft and tough, and is guaranteed not to harden or crack, and has a long service life.

[0045] Through the arrangement of the above structure, the dust curtain installation box 21 and the dust curtain 24 can effectively absorb the passing dust through the effect of static electricity, and the dust will fall down by itself due to the effect of gravity, so as to achieve the effect of self-dust reduction.

[0046] Embodiment 4

[0047] In conjunction with Embodiments 1 to 3, please refer to Figure 5 , Fig. 9 and Fig.10As shown, the specific improvements are as follows: the scraper 7 is arranged on the top of the conveyor belt 203, and the driving assembly 8 is arranged on the inner side of the double-layer anti-overflow skirt 204, wherein the driving assembly 8 is a linear guide rail or a screw driving assembly, which is the prior art and is used to drive the scraper 7 to perform linear motion, and a movable connecting member 25 is arranged on one side of the driving assembly 8, and the movable connecting member 25 is a sliding seat slidably connected to the driving assembly 8, and the movable connecting member 25 and the scraper 7 are connected through a mounting assembly, and the mounting assembly includes two mounting plates 26, one of which is fixed on the surface of the movable connecting member 25, and the other is fixed on the surface of the scraper 7, and a threaded rod 27 is threadedly connected between the two mounting plates 26, and a hand nut 28 is threadedly arranged on one end of the threaded rod 27 that passes through the outside of the mounting plate 26, and an anti-loosening gasket 29 is sleeved on the surface of the threaded rod 27 and between the hand nut 28 and the mounting plate 26, for improving the connection stability of the hand nut 28;

[0048] Through the setting of the above-mentioned structure, the driving component 8 drives the scraper 7 to reciprocate on the conveyor belt 203, so as to clean the residual materials accumulated on the conveyor belt 203, ensure the smooth passage of materials inside the material guide trough, and avoid the residual materials from being mixed into different materials later. The scraper 7 can be quickly disassembled through the installation component, which is convenient for maintenance or replacement.

[0049] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0050] When in use, the guide trough body 2 is installed at the receiving part of the belt conveyor. The two sides of the guide trough body 2 are equipped with double-layer overflow prevention skirt plates 204 and wear-resistant side plates 205, which have excellent fitting and sealing performance. The double side plate sealing structure has a more ideal effect. The expansion arc upper cover plate 206 and the dust curtain 24 are used in combination to have an excellent dust reduction effect. Driven by the hydraulic cylinder 13, the guide trough body 2 can be lifted and lowered by the lifting frame 14. When conveying materials, the materials enter the guide trough body 2 through the feed channel 15. At this time, the pad 6 is impacted. Under the elastic force of the spring 5, the impact force of the material falling can be slowed down to protect the conveyor belt 203. At the same time, by starting the electric push rod 9, the U-shaped frame 12 is driven to move up and down, which can drive the rotating plates 3 on both sides to move up and down. During the movement of the rotating plates 3, the slider 11 rotates between the U-shaped frame 12 and slides in the chute 10. The angle adjustment of the two rotating plates 3 can control the material unloading speed and amount, further improving the stability during unloading, and avoiding excessive accumulation of materials on the conveyor belt 203, which affects the conveying efficiency.

[0051] After the conveying is completed, the drive components 8 on both sides are started to drive the scraper 7 to reciprocate on the conveyor belt 203, and the remaining materials accumulated on the conveyor belt 203 are cleaned. At the same time, the materials adhering to the conveyor belt 203 can also be scraped off to ensure that the materials in the guide trough pass smoothly. During the use of the scraper 7, the threaded rod 27 can be pulled out from between the two mounting plates 26 by screwing out the hand nut 28 and taking out the anti-loosening gasket 29, and then the scraper 7 can be removed from the drive component 8, which is convenient for maintenance or replacement of the scraper 7;

[0052] Since the dust curtain 24 is made of wear-resistant, flame-retardant and anti-static rubber material, it can effectively absorb the passing dust through the effect of static electricity, and fall down by itself due to gravity to achieve the effect of self-dust reduction. The dust curtain 24 is connected to the cover plate 22. During use, the dust curtain 24 can be directly taken out from the guide trough body 2 by moving the cover plate 22 above the dust curtain installation box 21 upwards and moving the limit rod 23 out of the installation box, so that the dust curtain 24 can be easily maintained.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
