Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, to a waste compression device. Background Technology

[0002] Waste disposal refers to the process of removing, rendering harmless, and recycling solid waste generated in daily life and production. Its core objective is to achieve the harmlessness, resource recovery, and reduction of waste, avoiding environmental pollution, resource waste, or harm to public health. To reduce waste volume and increase density, thus facilitating transportation, storage, and processing, waste is often compressed.

[0003] A search revealed that utility model patent CN220841571U discloses a waste treatment compression device, including a compression box, a pushing mechanism, and a compression mechanism. The compression box has a base at its lower front side. The pushing mechanism is located on the upper surface of the base. The compression mechanism is located at the upper end of the compression box. It also includes a door opening mechanism, which is located at the upper end of the compression box and is installed in conjunction with doorways on the front and rear sides of the compression box. A control switch group is fixedly connected to the left side of the compression box, and the input end of the control switch group is electrically connected to an external power source. The pushing mechanism includes a push plate, a lead screw, a connecting rod, and a second push plate. The pushing mechanism also includes a first motor. The compression mechanism includes a third motor, a worm gear, an external threaded column, an internal threaded sleeve, a second worm wheel, and a compression block. This waste treatment compression device reduces manual labor and avoids equipment tilting, thus eliminating limitations on the location of use.

[0004] However, the above-mentioned patents still have the following shortcomings: feeding, compression and unloading all take a certain amount of time, which affects the efficiency of waste compression and treatment, and it is not convenient to put waste into the compression box, nor is it convenient to transport the compressed waste. Therefore, we propose a compression device for waste treatment. Utility Model Content

[0029] In this embodiment, a rotating shaft is provided at the bottom of the turntable 2, and the turntable 2 is rotatably connected to the worktable 1 by the cooperation of the bearing and the rotating shaft. At the same time, the bottom surface of the compression box 3 is in contact with the top surface of the worktable 1. In addition, the device is controlled by a controller and powered by an external power supply. This is conventional prior art and will not be described in detail.

[0030] For details, please refer to Figure 1 and Figure 4 The feeding mechanism 5 includes two uprights 15 fixedly connected to the side of the workbench 1. The top of the two uprights 15 is fixedly connected to a feeding frame 16. The inner cavity of the feeding frame 16 is rotatably connected to three first conveying rollers 17. The three first conveying rollers 17 are drivenly connected to a feeding conveyor belt 18. The inner cavity of the feeding frame 16 is rotatably connected to a first support roller 20.

[0031] In this embodiment, a first servo motor 19 drives a first conveyor roller 17 to rotate counterclockwise, and the first conveyor roller 17 drives a feeding conveyor belt 18 to rotate counterclockwise. The feeding conveyor belt 18 feeds the garbage to be compressed, so that the garbage falls into the compression box 3. In addition, the first servo motor 19 and the first conveyor roller 17 can also be connected to a reducer for speed reduction. This is existing technology and will not be described in detail.

[0032] For details, please refer to Figure 1 , Figure 3 and Figure 5The material conveying mechanism 6 includes two connecting frames 21 fixedly connected to the bottom surface of the workbench 1. The bottom ends of the two connecting frames 21 are respectively fixedly connected to material conveying frames 22.

[0033] In this embodiment, the conveyor belt 24 is used to catch the garbage compression block falling from the chute 4, and the rotation of the conveyor belt 24 is used to transport the garbage compression block. In addition, the second servo motor 25 and the second conveying roller 23 can also be connected and decelerated by a reducer. This is the prior art and will not be described in detail.

[0034] For details, please refer to Figure 1 The transverse dimensions of the inner cavity of the compression box 3 are equal to the external dimensions of the extrusion plate 9 and the push plate 11.

[0035] In this embodiment, the extrusion plate 9 and the push plate 11 are ensured to be able to extend into the inner cavity of the compression box 3. The extrusion plate 9 is used to extrude and compress the waste in the inner cavity of the compression box 3, and the push plate 11 is used to push out the compressed waste block in the inner cavity of the compression box 3, so that the waste falls from the discharge chute 4 onto the conveyor belt 24.

[0036] For details, please refer to Figure 4 The side of the feeding conveyor belt 18 is in contact with the inner wall of the feeding rack 16.

[0037] In this embodiment, the inner wall of the feeding rack 16 is used to limit the side of the feeding conveyor belt 18 to prevent the garbage on the feeding conveyor belt 18 from falling off the side of the feeding conveyor belt 18.

[0038] For details, please refer to Figure 5 Multiple second support rollers 26 are rotatably connected between the two material conveying frames 22. The multiple second support rollers 26 penetrate the inner side of the material conveying belt 24. The top surface of the second support rollers 26 is in contact with the top surface of the inner side of the material conveying belt 24, and the side surface of the material conveying belt 24 is in contact with the inner side surface of the material conveying frame 22.

[0039] In this embodiment, the second support roller 26 is used to support the conveyor belt 24, and the inner side of the conveyor frame 22 is used to limit the side of the conveyor belt 24 to ensure the stability of the conveyor belt 24 between the two second conveyor rollers 23.

[0040] For details, please refer to Figure 1 and Figure 3The number of teeth on the outer side of the incomplete gear 14 is one-third the number of teeth on the outer side of the spur gear 12. The three compression boxes 3 are evenly arranged in a circle with the rotating shaft of the turntable 2 as the center.

[0041] In this embodiment, the stepper motor 13 drives the incomplete gear 14 to rotate one revolution, which in turn drives the spur gear 12 and the turntable 2 to rotate 120 degrees, so that the three compression boxes 3 move intermittently, and the three spur gears 12 move sequentially to the end of the feeding conveyor belt 18, directly below the extrusion plate 9 and the push plate 11.

[0042] Working principle: In use, firstly, the first servo motor 19 is started to drive the first conveyor roller 17 to rotate counterclockwise intermittently. The first conveyor roller 17 drives the feeding conveyor belt 18 to rotate counterclockwise, and the feeding conveyor belt 18 moves the garbage to be compressed upward, so that the garbage falls into the compression box 3 below the top of the feeding conveyor belt 18. Then, the stepper motor 13 is started to drive the incomplete gear 14 to rotate. Through the meshing transmission between the incomplete gear 14 and the spur gear 12, the turntable 2 and the three compression boxes 3 rotate synchronously by 120 degrees, so that the compression box 3 containing garbage moves to the bottom of the extrusion plate 9, and the other compression box 3 moves to the bottom of the feeding conveyor belt 18 for feeding. Then, the first electric telescopic rod 8 is started to drive the extrusion plate 9 to move up and down for one cycle, and the extrusion plate 9 uses the extrusion plate 9 to compress the garbage in the inner cavity of the compression box 3. The garbage is compressed into compressed garbage blocks. Finally, when the incomplete gear 14 and the spur gear 12 mesh again, the turntable 2 and the three compression boxes 3 rotate synchronously by 120 degrees. This causes the compressed garbage boxes 3 to move above the dropping chute 4. The second electric telescopic rod 10 drives the push plate 11 to move down, causing the compressed garbage blocks inside the compression box 3 to fall onto the conveyor belt 24. The second servo motor 25 is then activated to drive the second conveyor roller 23 and the conveyor belt 24 to rotate. The conveyor belt 24 transports the compressed garbage blocks. At the same time, another compression box 3 containing garbage moves below the extrusion plate 9 for compression, and the third compression box 3 moves below the top of the feeding conveyor belt 18 for feeding. This continuous compression of garbage ensures high work efficiency.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
