[0004] However, during the process of feeding hazardous waste through the conveyor belt, a small portion of the hazardous waste will remain on the conveyor belt. Since hazardous waste is inherently dangerous, the portion of hazardous waste adhering to the conveyor belt increases the subsequent cleaning processes and steps. Utility Model Content

[0005] To address the issues in existing technologies where a small portion of hazardous waste remains on the conveyor belt during the feeding process, and the added complexity and time required for subsequent cleaning due to the inherent dangers of hazardous waste, this invention provides a hazardous waste feeding device that automatically removes the portion of hazardous waste adhering to the conveyor belt surface. This prevents the waste from remaining on the belt and thus avoids unnecessary cleaning steps. Furthermore, the device eliminates the need for manual cleaning, enhancing safety and avoiding the adverse effects of manual hazardous waste removal on personnel. The specific technical solution is as follows: A hazardous waste feeding device includes a support frame, on which a conveying unit is mounted. The conveying direction of the conveying unit is from left to right, and a scraping mechanism is mounted at the output end on the right side of the conveying unit. The scraping mechanism includes a lifting seat that moves vertically upwards and downwards. A connecting plate is fixedly installed on the right side of the lifting seat. A drive frame is fixedly installed at the bottom end of the connecting plate. A lead screw is threaded through the drive frame in the vertical direction. A second motor is installed at the bottom end of the lead screw. The output end of the second motor is connected to the bottom end of the lead screw. An mounting plate is fixedly installed on the right side wall of the lifting seat. A baffle is fixedly installed at the top end of the mounting plate. A wedge surface is provided at the top end of the baffle.

[0006] In the above technical solution, the conveying unit is rotatably mounted on two conveying rollers on the left and right sides above the support frame. A conveyor belt is sleeved on the outside of the two conveying rollers. A first motor is provided at the front end of the support frame, and the output end of the first motor is connected to the left conveying roller. A reinforcing frame is provided in the middle of the support frame.

[0007] In the above technical solution, the second motor is mounted on the lower surface of the reinforcing frame.

[0008] In the above technical solution, the drive frame is U-shaped.

[0009] In the above technical solution, a guide mechanism is provided on the right side of the baffle; The guiding mechanism includes two fixed plates fixedly installed on the front and rear sides of the right end of the baffle. A fixed plate is fixedly installed on the front fixed plate, and a worm gear is rotatably mounted on the fixed plate. A rotating shaft is rotatably mounted between the two fixed plates. A worm wheel is fixedly installed at the front end of the rotating shaft. The worm gear and the worm wheel are meshed and connected. A first guide plate and a second guide plate are fixedly installed on the rotating shaft. The first guide plate rotatably fits against the wedge sidewall.

[0010] In the above technical solution, the cross-sectional shape of both the first guide plate and the second guide plate is set as an isosceles triangle.

[0011] In the above technical solution, the centerline corresponding to the bottom edge of the second guide plate is two to five times the centerline corresponding to the bottom edge of the first guide plate.

[0012] The hazardous waste feeding device of this utility model has the following advantages compared with the prior art: I. In the process of feeding hazardous waste via conveyor belt, a small amount of hazardous waste may remain on the conveyor belt. Since hazardous waste is inherently dangerous, the portion of hazardous waste adhering to the conveyor belt increases the need for subsequent cleaning processes. This utility model addresses this by installing a baffle and wedge at the right output end of the conveyor belt, which can automatically remove the portion of hazardous waste adhering to the conveyor belt surface. This avoids the need for additional cleaning processes due to the persistent presence of hazardous waste on the conveyor belt surface, saving unnecessary cleaning steps. Furthermore, the method of cleaning without requiring manual intervention is safer and avoids the adverse effects of manual cleaning of hazardous waste on people. II. By setting up a second motor, lead screw, drive frame, and lifting seat, this utility model can realize the baffle's contact with or separation from the right output end of the conveyor belt, flexibly change the position of the baffle and wedge surface, and thus achieve the cleaning of the baffle and wedge surface after the equipment is used. Third, by setting a first guide plate and a second guide plate, this utility model can guide and transport hazardous waste falling from the baffle and wedge to the next process, which facilitates the accurate guidance and feeding of the hazardous waste material to the next receiving device. IV. By setting up a worm gear, a worm wheel, a first guide plate, and a second guide plate, the angle of the first guide plate and the second guide plate can be adjusted so that the first guide plate can fit against the side wall of the baffle, preventing the material on the wedge surface and the baffle surface from falling through the gap between the first guide plate and the baffle.

[0013] In summary, this invention can automatically remove some hazardous waste adhering to the surface of the conveyor belt, avoiding the need for subsequent cleaning processes due to hazardous waste remaining on the conveyor belt surface, saving unnecessary subsequent cleaning steps. At the same time, the method of cleaning without human intervention is safer and avoids the adverse effects of manual cleaning of hazardous waste on people. Attached Figure Description

Detailed Implementation

[0015] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0016] See Figures 1 to 4 As shown, a hazardous waste feeding device includes a support frame 1, on which a conveying unit is provided. The conveying direction of the conveying unit is set from left to right, which can convey hazardous waste materials from left to right. A scraping mechanism is provided at the output end on the right side of the conveying unit. The scraping mechanism scrapes off the materials adhering to the conveying device, eliminating the need for manual cleaning. For details, please refer to [link / reference]. Figure 1 and Figure 2 As shown, the scraping mechanism includes a lifting seat 6 that moves vertically upwards and downwards. A connecting plate 7 is fixedly installed on the right side of the lifting seat 6. A drive frame 8 is fixedly installed at the bottom of the connecting plate 7. A lead screw 9 is threaded through the drive frame 8 in the vertical direction. A second motor 10 is installed at the bottom of the lead screw 9. The output end of the second motor 10 is connected to the bottom end of the lead screw 9. An installation plate 11 is fixedly installed on the right side wall of the lifting seat 6. A baffle 12 is fixedly installed at the top of the installation plate 11. A wedge surface 13 is provided at the top end of the baffle 12. The scraping mechanism is activated by the second motor 10. The screw 9 is rotated, which causes the drive frame 8 to move the mounting plate 11, the lifting seat 6 and the connecting plate 7 in a vertical direction. This allows the lifting seat 6 to move along the support frame 1, causing the baffle 12 and the wedge surface 13 to move closer to or further away from the surface of the conveyor belt 3. This allows for thorough maintenance and cleaning of the wedge surface 13 and the baffle 12 that are away from the surface of the conveyor belt 3 after the equipment is used. The wedge surface 13 can scrape off the material at the conveying device while preventing the material from remaining at the intersection of the baffle 12 and the top of the wedge surface 13.

[0017] See Figure 1 As shown, the conveying unit is rotatably mounted on two conveying rollers 2 on the left and right sides above the support frame 1 via bearings. A conveyor belt 3 is sleeved on the outer side of the two conveying rollers 2. A first motor 4 is installed at the front end of the support frame 1, and the output end of the first motor 4 is connected to the left conveying roller 2. A reinforcing frame 5 is installed in the middle of the support frame 1. The first motor 4 drives the left conveying roller 2 to rotate, which drives the conveyor belt 3 to rotate clockwise, so as to make the left and right conveying rollers 2 rotate synchronously, so as to realize the conveying of hazardous waste material at the top of the conveyor belt 3 clockwise to the right. A second motor 10 is installed on the lower surface of the reinforcing frame 5, and the reinforcing frame 5 provides a position for the installation of the second motor 10.

[0018] In order to enable the drive frame 8 to drive the mounting plate 11 to move while being connected to the lead screw 9, the drive frame 8 is U-shaped, so as to ensure that the lead screw 9 is threadedly connected to the drive frame 8 without interfering with the top of the drive frame 8.

[0019] See also 3 and Figure 4 As shown, a guide mechanism is provided on the right side of the baffle 12. The guide mechanism includes two fixed plates 14 fixedly installed on the front and rear sides of the right end of the baffle 12. A fixed plate 15 is fixedly installed on the front fixed plate 14. A worm gear 16 is rotatably installed on the fixed plate 15. A rotating shaft 17 is rotatably installed between the two fixed plates 14. A worm wheel 18 is fixedly installed on the front end of the rotating shaft 17. The worm gear 16 is meshed with the worm wheel 18. A first guide plate 19 and a second guide plate 20 are fixedly installed on the rotating shaft 17. The first guide plate 19 rotates to fit against the side wall of the wedge surface 13. Since the wedge surface 13 is in contact with the surface of the conveyor belt 3, as the conveyor belt 3 rotates clockwise and the baffle 12 and the wedge surface 13 remain in the same position, the hazardous waste material adhering to the surface of the conveyor belt 3 can be scraped off to the first guide plate 19, so that the hazardous waste is automatically scraped off and cleaned up. As most of the hazardous waste is conveyed to the next process through the surfaces of the first guide plate 19 and the second guide plate 20, In addition, by adjusting the rotation of the worm gear 16, the worm wheel 18 and the rotating shaft 17 can be made to rotate synchronously, thereby causing the first guide plate 19 to be in contact with or away from the side wall of the wedge surface 13, so as to adjust the relative position of the first guide plate 19 and the wedge surface 13. When the first guide plate 19 is not in use, the first guide plate 19 can be made to disengage from the wedge surface 13 by rotating the first guide plate 19 clockwise, so as to achieve a complete cleaning of the first guide plate 19.

[0020] The cross-sectional shape of the first guide plate 19 and the second guide plate 20 is set as an isosceles triangle, so as to ensure that the first guide plate 19 can fit the wedge surface 13 while avoiding the material from staying at the intersection of the first guide plate 19 and the wedge surface 13 and affecting the feeding.

[0021] In addition, the center line corresponding to the bottom edge of the second guide plate 20 is two to five times the center line corresponding to the bottom edge of the first guide plate 19. When the center line corresponding to the bottom edge of the second guide plate 20 is any multiple of two to five times the center line corresponding to the bottom edge of the first guide plate 19, it can guide the material to the right side of the conveyor belt 3 while ensuring that the conveyor belt 3 is connected to the material receiving device, thus avoiding the second guide plate 20 being too short and affecting the next process of material receiving.

[0022] It is worth noting that the first motor 4 and the second motor 10 used in this application are commonly available self-locking motors with lockable output terminals. When they are stopped, their output terminals can lock themselves and will not rotate under external force. The above-mentioned existing components will not be described in detail here.

[0023] The working principle of the hazardous waste feeding device in this embodiment is as follows: The first motor 4 is turned on to drive the left conveyor roller 2 to rotate, which in turn drives the conveyor belt 3 to rotate clockwise, so that the left and right conveyor rollers 2 rotate synchronously, and the hazardous waste material at the top of the conveyor belt 3 is conveyed clockwise to the right. When the hazardous waste material adhering to the surface of the conveyor belt 3 rotates to the wedge surface 13, since the wedge surface 13 is in contact with the surface of the conveyor belt 3, as the conveyor belt 3 rotates clockwise and the baffle 12 and the wedge surface 13 remain in the same position, the hazardous waste material adhering to the surface of the conveyor belt 3 can be scraped off to the first guide plate 19, so that the hazardous waste is automatically scraped off and cleaned up. As most of the hazardous waste is transported to the next process through the surfaces of the first guide plate 19 and the second guide plate 20; By adjusting the rotation of the worm gear 16, the worm wheel 18 and the rotating shaft 17 can be made to rotate synchronously, thereby causing the first guide plate 19 to be in contact with or away from the side wall of the wedge surface 13, so as to adjust the relative position of the first guide plate 19 and the wedge surface 13. When the first guide plate 19 is not in use, the first guide plate 19 can be made to disengage from the wedge surface 13 by rotating the first guide plate 19 clockwise, so as to achieve a thorough cleaning of the first guide plate 19. The second motor 10 is turned on to make the lead screw 9 rotate, so that the drive frame 8 drives the mounting plate 11, the lifting seat 6 and the connecting plate 7 to move vertically in sync, so that the lifting seat 6 moves along the support frame 1, and makes the baffle 12 and the wedge surface 13 move closer to or away from the surface of the conveyor belt 3, so that the wedge surface 13 and the baffle 12 away from the surface of the conveyor belt 3 can be thoroughly maintained and cleaned after the equipment is used up. This invention can automatically remove some hazardous waste adhering to the surface of the conveyor belt 3, avoiding the need for subsequent cleaning processes due to hazardous waste always adhering to the surface of the conveyor belt 3, saving unnecessary subsequent cleaning steps. At the same time, the method of cleaning without human intervention is safer and avoids the adverse effects of manual cleaning of hazardous waste on people.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
