[0012] Optionally, the driving assembly further includes a sealing box, which is fixedly disposed in the material guide trough body, and the first bevel gear and the second bevel gear are both located in the sealing box.

[0013] By adopting the above technical solution, the sealing box wraps the first bevel gear and the second bevel gear in the material guide trough body, so that the dust pollution generated during material transportation is not easy to drive the gears to cause abnormal wear due to dust accumulation.

[0014] Optionally, the adjusting assembly includes a spring, an air intake pipe, a rotating plate and a limiting telescopic plate; the spring is located in the plateless cavity of the anti-overflow telescopic plate, and its two ends are fixedly connected to the fixed end of the anti-overflow telescopic plate and the movable end of the anti-overflow telescopic plate respectively, and the spring is in a compressed state; one end of the air intake pipe is connected to the plateless cavity of the anti-overflow telescopic plate, and the other end is connected to the outside world; the rotating plate is rotatably arranged in the air intake pipe; the limiting telescopic plate is located on one side of the rotating plate, the fixed end of the limiting telescopic plate is fixedly connected to the air intake pipe, and the limiting telescopic plate is electrically connected to the controller.

After the air in the feed pipe flows, the gas in the circulation pipe is sucked into the feed pipe, and the gas at the bottom of the circulation pipe forms a slight negative pressure, which makes it easy for the dust floating in the material guide trough body to be sucked into the circulation pipe, thereby reducing the dust in the material guide trough body.

[0027] Material enters the chute body 3 through the feed pipe 31. The guide plate 32 concentrates the material on the belt of the belt conveyor 2. When the material transport volume is small, the drive assembly 4 adjusts the inclination angle of the guide plate 32 to facilitate the concentration of the material on the belt of the belt conveyor 2. When the material transport volume is large, the drive assembly 4 adjusts the inclination angle of the guide plate 32 to increase the contact surface between the belt of the belt conveyor 2 and the material, making it less likely for the material to accumulate in the chute body 3.

[0028] Reference Figure 2 and Figure 3A supporting plate 311 is fixedly mounted within the feed pipe 31, near the discharge section of the belt chute body 3. This rectangular plate-shaped supporting plate 311 is arranged to tilt downward from the feed section away from the belt conveyor 2 to the feed section close to the belt conveyor 2. A guide plate 32 is also arranged to tilt downward from the side close to the frame 1 to the side away from the frame 1. Two guide plates 32 are provided, one on each side of the width of the chute body 3.

[0029] Reference Figure 1 and Figure 2 , an anti-overflow telescopic plate 33 is fixedly provided on the side wall of the guide plate 32 close to the frame 1, and the movable end of the anti-overflow telescopic plate 33 abuts the belt of the belt conveyor 2. Two anti-overflow telescopic plates 33 are provided, and they correspond one to one with the guide plates 32. A dust curtain 34 is vertically provided on the side of the guide trough body 3 away from the feeding section of the belt conveyor 2, and the dust curtain 34 is connected to the guide trough body 3 in a sliding direction along the vertical direction. A controller 35 is fixedly installed on the top of the guide trough body 3. A circulation pipe 36 is provided on one side of the feed pipe 31. The circulation pipe 36 is in the shape of a rectangular tube, and its two ends are respectively connected to the feed pipe 31 and the guide trough body 3. The connection point between the circulation pipe 36 and the feed pipe 31 is located below the supporting plate 311.

[0030] Reference Figure 2 、 Figure 4 and Figure 5 , there are two groups of drive components 4, which correspond one to one with the two guide plates 32. The drive component 4 includes a guide block 41, a drive block 42, a drive unit 43 and a sealing box 44. The guide block 41 is horizontally arranged on one side of the guide plate 32 and is fixedly connected to the guide plate 32. A guide slope is provided on the side of the guide block 41 away from the guide plate 32. The guide slope is inclined from the side close to the feeding section of the belt conveyor 2 to the side away from the feeding section of the belt conveyor 2 toward the direction close to the guide plate 32. The drive block 42 is horizontally arranged on one side of the guide block 41 and is in the shape of a rectangular block. The drive block 42 and the guide trough body 3 are slidably connected along the length direction of the guide trough body 3 through a T-shaped slider and a T-shaped slide groove. A rubber pad 421 is fixedly provided on one side of the drive block 42, and the rubber pad 421 abuts against the guide block 41.

[0031] Reference Figure 4 and Figure 5The driving part 43 is located on the guide trough body 3 and is used to drive the driving block 42 to slide. The driving part 43 includes a motor 431, a first bevel gear 432, a second bevel gear 433 and a lead screw 434. The motor 431 is horizontally mounted on the guide trough body 3, and the motor 431 is electrically connected to the controller 35. The first bevel gear 432 is vertically arranged in the guide trough body 3 and is fixedly connected to the output shaft of the motor 431. The second bevel gear 433 is vertically arranged in the guide trough body 3 and is meshed with the first bevel gear 432. The lead screw 434 is horizontally arranged and fixedly connected to the second bevel gear 433. The lead screw 434 is rotatably arranged in the guide trough body 3 through a bracket, and the lead screw 434 is threadedly connected to the driving block 42. The sealing box 44 is vertically arranged in the guide trough body 3 and is in the shape of a rectangular box. The sealing box 44 is fixedly connected to the guide trough body 3. The first bevel gear 432 and the second bevel gear 433 are both located in the sealing box 44 . The output shaft of the motor 431 is rotatably connected to the sealing box 44 , and the lead screw 434 is rotatably connected to the sealing box 44 .

[0032] When the material transportation volume is small, the controller 35 controls the output shaft of the motor 431 to rotate forward, the output shaft of the motor 431 drives the first bevel gear 432 to rotate, the first bevel gear 432 drives the second bevel gear 433 to rotate, the second bevel gear 433 drives the screw 434 to rotate, the screw 434 drives the driving block 42 to slide toward the direction of the feeding section of the belt conveyor 2, the driving block 42 pushes the guide block 41 through the rubber pad 421, the guide block 41 drives the guide plate 32 to rotate, and the adjusting component 5 drives the movable end of the anti-overflow telescopic plate 33 to extend.

[0033] When the material transportation volume is large, the controller 35 controls the output shaft of the motor 431 to rotate in the opposite direction. The output shaft of the motor 431 drives the screw 434 to rotate through the first bevel gear 432 and the second bevel gear 433. The screw 434 drives the driving block 42 to slide in the direction away from the feeding end of the belt conveyor 2. The guide plate 32 slides naturally under the influence of gravity, so that the guide block 41 is always in contact with the rubber pad 421 on the driving block 42. The adjustment component 5 drives the movable end of the anti-overflow telescopic plate 33 to retract, so that the contact surface between the belt of the belt conveyor 2 and the material is easy to adjust.

[0034] Reference Figure 2 and Figure 6The adjustment assembly 5 is provided with two groups, one corresponding to each of the two overflow-proof telescopic plates 33. The adjustment assembly 5 includes a spring 51, an air inlet pipe 52, a rotating plate 53, and a limiting telescopic plate 54. The spring 51 is located within the plateless cavity of the overflow-proof telescopic plate 33 and is arranged parallel to the overflow-proof telescopic plate 33. The two ends of the spring 51 are fixedly connected to the fixed end and the movable end of the overflow-proof telescopic plate 33, respectively, and the spring 51 is in a compressed state. The air inlet pipe 52 is rectangular in shape, with one end of the air inlet pipe 52 connected to the plateless cavity of the overflow-proof telescopic plate 33 and the other end connected to the outside world. The rotating plate 53 is vertically arranged within the air inlet pipe 52 and is in the shape of a rectangular plate. The rotating plate 53 is rotatably connected to the air inlet pipe 52. The limiting telescopic plate 54 is located on the side of the rotating plate 53 away from the overflow-proof telescopic plate 33. The fixed end of the limiting telescopic plate 54 is fixedly connected to the air inlet pipe 52. The limiting telescopic plate 54 is an electric telescopic rod and is electrically connected to the controller 35.

[0035] Reference Figure 1 The lifting assembly 6 includes a support frame 61 and a telescopic lifting rod 62. The support frame 61 is vertically mounted on the top of the guide chute body 3 and is fixedly connected to the guide chute body 3. The telescopic lifting rod 62 is vertically mounted, with its fixed end fixedly connected to the support frame 61, and its movable end fixedly connected to the dust curtain 34. The telescopic lifting rod 62 is electrically powered and electrically connected to the controller 35.

[0036] When the material transport volume is small, the controller 35 controls the movable end of the lifting and telescopic rod 62 to extend, and the movable end of the lifting and telescopic rod 62 drives the dust curtain 34 to slide downward. When the guide block 41 drives the guide plate 32 to rotate, the compressed spring 51 returns to its original position, and outside air flows into the plateless cavity of the anti-overflow telescopic plate 33 through the air inlet pipe 52. The movable end of the anti-overflow telescopic plate 33 always closely contacts the belt surface of the belt conveyor 2. When the transported material presses the movable end of the anti-overflow telescopic plate 33, the movable end of the limit telescopic plate 54 limits the rotating plate 53. The gas in the plateless cavity of the anti-overflow telescopic plate 33 is not easily discharged to the outside through the air inlet pipe 52, making the movable end of the anti-overflow telescopic plate 33 difficult to retract.

[0037] When the material transport volume is large, the controller 35 controls the movable end of the lifting and telescopic rod 62 to retract, which drives the dust curtain 34 to slide upward. When the guide block 41 drives the material guide plate 32 to rotate, the controller 35 controls the movable end of the limit telescopic plate 54 to retract, and the limit telescopic plate 54 stops limiting the position of the rotating plate 53. The distance between the fixed end of the anti-overflow telescopic plate 33 and the belt of the belt conveyor 2 decreases, and the movable end of the anti-overflow telescopic plate 33 retracts, and the gas in the plate cavity of the anti-overflow telescopic plate 33 is discharged to the outside through the air inlet pipe 52.

[0038] Reference Figure 2, there are two groups of sealing assemblies 7, and they are respectively located on both sides of the width direction of the guide trough body 3. The sealing assembly 7 includes a wear-resistant plate 71, a first mounting plate 72 and a second mounting plate 73. The wear-resistant plate 71 is located at the bottom end of the guide trough body 3, and is hinged to the guide trough body 3 by a hinge. The wear-resistant plate 71 abuts against the non-working belt surface of the belt conveyor 2. The first mounting plate 72 is located on the side of the wear-resistant plate 71 away from the belt conveyor 2, and is in the shape of a rectangular plate. The first mounting plate 72 is fixedly connected to the wear-resistant plate 71 by bolts. The second mounting plate 73 is located on one side of the frame 1, and is in the shape of a rectangular plate. The second mounting plate 73 is fixedly connected to the first mounting plate 72, and the second mounting plate 73 is fixedly connected to the frame 1 by bolts. A plurality of first mounting plates 72 and second mounting plates 73 are arranged at intervals along the length direction of the frame 1.

[0039] When in use, the wear-resistant plate 71 abuts against the non-working belt surface of the belt conveyor 2, the anti-overflow telescopic plate 33 abuts against the working belt surface of the belt conveyor 2 to form a primary seal, and the wear-resistant plate 71 abuts against the non-working belt surface of the belt conveyor 2 to form a secondary seal, thereby realizing double sealing of the material guide trough body 3.

[0040] The implementation principle of a fully sealed material guide trough for a belt conveyor in the embodiment of the present application is as follows: Material enters the chute body 3 through the feed pipe 31. The guide plate 32 concentrates the material onto the belt of the belt conveyor 2. The anti-overflow telescopic plate 33 abuts the working belt surface of the belt conveyor 2 to form a primary seal, and the wear-resistant plate 71 abuts the non-working belt surface of the belt conveyor 2 to form a secondary seal. When the transported material presses against the movable end of the anti-overflow telescopic plate 33, the movable end of the limit telescopic plate 54 limits the position of the rotating plate 53. This prevents the gas in the non-plate cavity of the anti-overflow telescopic plate 33 from being easily discharged to the outside through the air inlet pipe 52, making the movable end of the anti-overflow telescopic plate 33 difficult to retract.

[0041] When the material transport volume is small, the controller 35 controls the movable end of the lifting and telescopic rod 62 to extend, and the movable end of the lifting and telescopic rod 62 drives the dust curtain 34 to slide downward. The controller 35 controls the output shaft of the motor 431 to rotate in the forward direction. The output shaft of the motor 431 drives the lead screw 434 to rotate through the first bevel gear 432 and the second bevel gear 433. The lead screw 434 drives the drive block 42 to slide toward the feed section of the belt conveyor 2. The drive block 42 pushes the guide block 41 through the rubber pad 421. The guide block 41 drives the guide plate 32 to rotate, and the compressed spring 51 returns to its original position. The outside air flows into the plateless cavity of the anti-overflow telescopic plate 33 through the air inlet pipe 52, and the movable end of the anti-overflow telescopic plate 33 always closely contacts the belt surface of the belt conveyor 2.

[0042] When the material transport volume is large, the controller 35 controls the movable ends of the telescopic lifting rod 62 and the limiting telescopic plate 54 to retract. The movable end of the telescopic lifting rod 62 drives the dust curtain 34 to slide upward, and the limiting telescopic plate 54 stops limiting the rotating plate 53. The controller 35 controls the output shaft of the motor 431 to rotate in the opposite direction. The output shaft of the motor 431 drives the lead screw 434 to rotate through the first bevel gear 432 and the second bevel gear 433. The lead screw 434 drives the drive block 42 to slide away from the feed end of the belt conveyor 2. The guide plate 32 naturally drops under the influence of gravity, so that the guide block 41 always contacts the rubber pad 421 on the drive block 42. The distance between the fixed end of the anti-overflow telescopic plate 33 and the belt of the belt conveyor 2 is reduced. The movable end of the anti-overflow telescopic plate 33 retracts, and the gas in the plate cavity of the anti-overflow telescopic plate 33 is discharged to the outside through the air inlet pipe 52. This makes the contact surface between the belt of the belt conveyor 2 and the material easier to adjust, thereby preventing material from accumulating in the guide trough body 3.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
