Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to an auxiliary recycling device for stone waste. Background Technology

[0002] During stone processing, steps such as cutting, grinding, and carving generate a large amount of stone waste, including stone powder, stone chips, and small pieces of stone scraps. To avoid impacting the working environment and to achieve resource recycling, the stone waste generated during processing is recycled. For easier sorting, the waste is classified according to different particle sizes, mostly through a screening screen. The recycled stone waste is poured into the screen and falls onto the screen, separating large and small particles. However, the stone waste falls in a fixed position upon entering the screen, primarily in the middle of the screen. This causes a large accumulation of stone particles in the middle, affecting the screening of other stone waste. Furthermore, due to the weight of the stone waste, continuous falling into the middle of the screen can cause it to sag, damaging the entire screen and shortening its lifespan. Utility Model Content

[0003] Therefore, this utility model proposes an auxiliary recycling device for stone waste, which can adjust the falling position of stone waste to avoid accumulation and damage to the screen.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A stone waste auxiliary recycling device includes a recycling box, a feed pipe, a screen, and a uniform feeding mechanism. The top surface of the recycling box has an opening, and the bottom end of the feed pipe extends into the recycling box from the opening and is rotatably connected to the opening. The screen is located inside the recycling box and below the opening. The uniform feeding mechanism includes a rotary motor, a gear, a rack, a receiving plate, a guide plate, a side plate, an electric turntable, and an elliptical rod. The rotary motor is located on the top surface of the recycling box, and its output shaft is connected to the gear. The rack is arranged circumferentially along the outer wall of the feed pipe, and the gear meshes with the rack. The receiving plate is located inside the feed pipe, and its top surface has a symmetrically arranged feeding groove. The top surface of the guide plate is rotatably connected to the bottom surface of the receiving plate and is located on one side of the feeding groove. The side plates are arranged opposite each other on the bottom surface of the receiving plate. The electric turntable is arranged on the opposite side wall of the side plates. The two ends of the elliptical rod are connected to the rotation surface of the electric turntable, and the guide plate is located on both sides of the elliptical rod.

[0006] Preferably, it also includes a feed funnel, which is disposed on the top surface of the feed pipe.

[0007] Preferably, the uniform feeding mechanism includes a slider, the inner wall of the opening is provided with an annular groove, and the slider is disposed on the outer wall of the feed pipe and located in the annular groove.

The output shaft of the electric push rod is connected to one side of the inclined plate, and the bottom end of the feed pipe is located above the moving path of the inclined plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model provides an auxiliary recycling device for stone waste. When stone waste is poured into the recycling box from the feed pipe, it falls onto the receiving plate and then drops from the discharge channels on both sides. A guide plate is provided on one side below the discharge channels. When the electric turntable drives the guide rod to rotate, it can push the guide plate to rotate outward, thereby changing the discharge position of the stone waste. At the same time, during the discharge process, the rotary motor can drive the gear to rotate, and the gear drives the feed pipe to rotate through the rack, changing the position of the discharge channels. This allows the stone waste to fall to different positions on the screen, preventing the stone waste from accumulating in the middle of the screen and affecting normal discharge. It also prevents the middle of the screen from being damaged by excessive impact, thus extending the service life of the screen. Attached Figure Description

[0019] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0020] See Figures 1 to 3 This utility model provides an auxiliary recycling device for stone waste, including a recycling box 1, a feeding pipe 2, a screen 3, and a uniform feeding mechanism. The recycling box 1 has an opening 4 on its top surface. The bottom end of the feeding pipe 2 extends into the recycling box 1 through the opening 4 and is rotatably connected to the opening 4. The screen 3 is disposed inside the recycling box 1 and located below the opening 4. The uniform feeding mechanism includes a rotary motor 5, a gear 6, a rack 7, a receiving plate 8, a guide plate 9, a side plate 10, an electric turntable 11, and an elliptical rod 12. The rotary motor 5 is located on the top of the recycling box 1. The output shaft of the feed pipe 2 is connected to the gear 6. The rack 7 is arranged circumferentially along the outer wall of the feed pipe 2. The gear 6 meshes with the rack 7. The receiving plate 8 is arranged inside the feed pipe 2. The top surface of the receiving plate 8 is symmetrically provided with a discharge channel 13. The top surface of the guide plate 9 is rotatably connected to the bottom surface of the receiving plate 8 and is located on one side of the discharge channel 13. The side plates 10 are arranged opposite to each other on the bottom surface of the receiving plate 8. The electric turntable 11 is arranged on the opposite side wall of the side plates 10. The two ends of the elliptical rod 12 are connected to the rotation surface of the electric turntable 11. The guide plate 9 is located on both sides of the elliptical rod 12.

[0021] After the waste generated during stone processing is collected, it can be poured into the feed pipe 2. A receiving plate 8 is set at the bottom of the feed pipe 2, and a discharge channel 13 is set on both sides of the receiving plate 8. The stone waste can fall from the discharge channel 13 into the recycling box 1 and onto the screen 3. The screen 3 can be used to screen the stone waste. Small-sized stone waste can pass through the screen 3 and fall to the bottom of the recycling box 1, while large-sized stone waste will be intercepted on the screen 3. After the screened stone waste is recycled, it can be used in other processing applications, realizing the effective utilization of resources.

[0022] A guide plate 9 is installed on one side of the bottom of the feeding trough 13, and an elliptical rod 12 is between the guide plates 9. The electric turntable 11 can drive the elliptical rod 12 to rotate. When the short axis of the elliptical rod 12 is horizontal, the guide plate 9 is in a vertical state. As the electric turntable 11 drives the elliptical rod 12 to rotate, the guide plate 9 will be pushed outward. After the stone waste passing through the feeding trough 13 comes into contact with the guide plate 9, it will change its feeding position, thereby avoiding the accumulation of stone waste in the middle of the screen 3, so that the stone waste can be dispersed and fed evenly. In addition, the feed pipe 2 and the opening 4 are rotatably connected. The rotary motor 5 can drive the gear 6 to rotate. The gear 6 can drive the feed pipe 2 to rotate through the rack 7, thereby changing the position of the feeding trough 13, further changing the feeding position of the stone waste, so that the stone waste falls more evenly onto the screen 3, avoiding the screen 3 from being subjected to more impact and thus reducing its lifespan.

[0023] Preferably, it also includes a feed funnel 14, which is disposed on the top surface of the feed pipe 2.

[0024] The feed hopper 14 can collect stone waste, allowing it to smoothly enter the feed pipe 2.

[0025] Preferably, the uniform feeding mechanism includes a slider 15, the inner wall of the opening 4 is provided with an annular groove 16, and the slider 15 is disposed on the outer wall of the feed pipe 2 and located in the annular groove 16.

[0026] When the feed pipe 2 rotates, the slider 15 can rotate along the annular groove 16, ensuring that the feed pipe 2 can rotate stably.

[0027] Preferably, it also includes a door 17, which is disposed on the side wall of the recycling bin 1 and located on one side of the screen 3.

[0028] The door 17 can be opened to allow the stone waste on and off the screen 3 to be removed from the recycling bin 1.

[0029] Preferably, the uniform feeding mechanism further includes a hinge 18, and the top surface of the guide plate 9 is connected to the bottom surface of the receiving plate 8 through the hinge 18.

[0030] When the elliptical rod 12 pushes the guide plate 9 to rotate, it can rotate around the hinge 18. When the major axis of the elliptical rod 12 leaves the guide plate 9, the guide plate 9 can rotate back under the action of gravity and return to a vertical state.

[0031] Preferably, the uniform feeding mechanism further includes an arc-shaped protrusion 19, which is disposed in the middle of the receiving plate 8, and the feeding channel 13 is located on both sides of the arc-shaped protrusion 19.

[0032] Stone waste falling onto the receiving plate 8 can roll to both sides under the action of the arc-shaped protrusion 19 and fall out of the discharge channel 13.

[0033] Preferably, the uniform feeding mechanism further includes an electric push rod 20 and an inclined plate 21. The electric push rod 20 is inclinedly disposed on the top surface inside the recycling box 1, with its output shaft facing below the center of the feed pipe 2. The output shaft of the electric push rod 20 is connected to one side of the inclined plate 21, and the bottom end of the feed pipe 2 is located above the moving path of the inclined plate 21.

[0034] The electric push rod 20 can move the inclined plate 21 to the bottom of the discharge channel 13. The stone waste falling in the discharge channel 13 can fall onto the inclined plate 21. The inclined plate 21 can guide the stone waste to the middle of the screen 3. On the one hand, the middle of the screen 3 can screen the stone, and on the other hand, it can unload the impact when the stone falls, reducing the wear of the screen 3.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
