Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to an auxiliary device for solid waste crushing for urban environmental protection. Background Technology

[0002] Environmental protection refers to all actions taken by humankind to solve existing or potential environmental problems, coordinate the relationship between humans and the environment, and ensure the sustainable development of the economy and society. In environmental protection, solid waste crushing helps to reduce waste at the source. Untreated solid waste is quite large in volume and occupies a lot of land space for landfill or temporary storage. In existing technologies, when using solid waste crushing equipment to crush some non-metallic, relatively loose, lightweight solid waste, such as plastic foam and paper, the feeding speed is reduced because the loose, lightweight solid waste takes up a lot of space, which in turn reduces the overall amount of solid waste processed. Therefore, to address the above problems, an auxiliary device for solid waste crushing for urban environmental protection is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model overcomes the existing defects and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An auxiliary device for solid waste crushing in urban environmental protection includes a waste crushing device. A fixed cover is fixedly connected to the top of the feed hopper of the waste crushing device. A conveyor is fixedly connected to the right end of the fixed cover. A bracket is fixedly connected to the top of the fixed cover. A motor is fixedly connected to the top of the bracket. A threaded shaft that is rotatably connected to the fixed cover is fixedly connected to the end of the motor's main shaft. A slider that is slidably connected to the bracket is helically connected to the outside of the threaded shaft. A fixed rod that penetrates the slider and the fixed cover is in contact with the bottom left side of the slider. The fixed rod is in contact with the fixed cover. A fixed seat that is in contact with the fixed cover is fixedly connected to the bottom of the fixed rod. A pressure plate is in contact with the bottom inner side of the fixed seat. A controller is fixedly connected to the left end of the fixed cover.

[0006] As a further improvement of this utility model, a first control switch is fixedly connected to the right side of both the upper and lower ends of the slider, and the first control switch at the top end is in contact with the bracket.

[0007] As a further improvement of this utility model, a fixed shaft that is rotatably connected to the fixed seat is fixedly connected to the left inner side of the pressure plate. A spring is fixedly connected to both the front and rear ends of the fixed shaft, and the other end of the spring is fixedly connected to the fixed seat. A magnetic plate is fixedly connected to the top of the pressure plate and the top inner side of the fixed cover. The magnetic plates at the top and bottom are of the same polarity and face each other. The angle rotation range of the pressure plate is 0° to 45°.

[0008] As a further improvement of this utility model, the outer top of the fixed rod is provided with a spring and a sliding plate arranged vertically, and the sliding plate is in contact with the slider. The sliding plate is fixedly connected to the fixed rod, the bottom end of the spring is in contact with the sliding plate, and a second control switch is fixedly connected to the top of the fixed rod.

[0009] As a further improvement of this utility model, the top end of the spring is in contact with a threaded plug, and the threaded plug is helically connected to the slider.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. An auxiliary device for crushing solid waste for urban environmental protection, comprising a threaded shaft, a slider, a fixed rod, a fixed seat, a pressure plate, and a first control switch, wherein when crushing some non-metallic, relatively loose, lightweight solid waste, after the conveyor is started to transport the solid waste into the fixed cover at the top of the feed hopper of the waste crushing equipment, the motor is started. At this time, the motor drives the threaded shaft to connect with the slider in a spiral manner. The slider drives the pressure plate to move down through the fixed rod and the fixed seat to press down the solid waste. When the slider moves down to trigger the first control switch at the bottom, the motor reverses to reset the slider and the pressure plate. When the slider resets and triggers the first control switch at the top, the pressure plate repeats the above operation to continue pressing down the solid waste. By controlling the reciprocating motion of the pressure plate to assist in pressing down some non-metallic, relatively loose, lightweight solid waste, the space occupied can be reduced, thereby accelerating the feeding speed and increasing the overall solid waste processing capacity.

[0012] 2. An auxiliary device for solid waste crushing in urban environmental protection, comprising a pressure plate, a fixed shaft, a spring, and a magnetic plate, wherein during the process of controlling the pressure plate to return to its upward position, when the pressure plate just returns to the top of the conveyor, the magnetic plates at the top of the pressure plate and the magnetic plates at the top of the inner side of the fixed cover repel each other due to their similar polarities. Furthermore, as the fixed seat at the bottom of the fixed rod drives the pressure plate to continue moving upward, the pressure plate continuously tilts. As the pressure plate drives the fixed shaft to rotate, the spring continuously contracts, allowing the solid waste conveyed on the top of the pressure plate to continuously slide down the tilted pressure plate, thereby preventing some solid waste from accumulating on the top of the pressure plate.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figure 1-3 As shown, an auxiliary device for solid waste crushing for urban environmental protection includes a waste crushing device 1. A fixed cover 2 is fixedly connected to the top of the feed hopper of the waste crushing device 1. A conveyor 3 is fixedly connected to the right end of the fixed cover 2. A bracket 4 is fixedly connected to the top of the fixed cover 2. A motor 5 is fixedly connected to the top of the bracket 4. A threaded shaft 6, which is rotatably connected to the fixed cover 2, is fixedly connected to the outside of the threaded shaft 6. A slider 7, which is slidably connected to the bracket 4, is screwed to the outside of the threaded shaft 6. A fixed rod 9, which penetrates the slider 7 and the fixed cover 2, is in contact with the bottom left side of the slider 7. The fixed rod 9 is in contact with the fixed cover 2. A fixed seat 10, which is in contact with the fixed cover 2, is fixedly connected to the bottom of the fixed rod 9. A pressure plate 11 is in contact with the bottom inner side of the fixed seat 10. A controller 19 is fixedly connected to the left end of the fixed cover 2.

[0021] Example 2

[0022] like Figure 2As shown, in order to solve the problem that it is not convenient to automatically control the motor 5 to reverse after the slider 7 drives the pressure plate 11 to the bottom or top through the fixed rod 9 and the fixed seat 10, a first control switch 8 is fixedly connected to the right side of both the upper and lower ends of the slider 7, and the first control switch 8 at the top is in contact with the bracket 4. After the slider 7 drives the pressure plate 11 to the bottom or top through the fixed rod 9 and the fixed seat 10, the first control switch 8 on the corresponding side is triggered by the slider 7, which facilitates the automatic control of the motor 5 to reverse.

[0023] Example 3

[0024] like Figure 2-3 As shown, to address the issue of solid waste accumulating on the top of the pressure plate 11 when it resets upwards, a fixed shaft 12, rotatably connected to the fixed base 10, is fixedly connected to the inner left end of the pressure plate 11. A spring-loaded spring 13 is fixedly connected to both the front and rear ends of the outer side of the fixed shaft 12, with the other end of the spring-loaded spring 13 fixedly connected to the fixed base 10. Magnetic plates 18 are fixedly connected to the top of the pressure plate 11 and the inner top of the fixed cover 2, with the top and bottom magnetic plates 18 having the same polarity. In contrast, the angle rotation range of the pressure plate 11 is from 0° to 45°. During the process of controlling the pressure plate 11 to reset upward, when the pressure plate 11 just resets to the top of the conveyor 3, the magnetic plate 18 at the top of the pressure plate 11 and the magnetic plate 18 at the top of the inner side of the fixed cover 2 repel each other, causing the pressure plate 11 to tilt. This further drives the fixed shaft 12 to rotate, causing the spring 13 to continuously contract, which facilitates the automatic sliding of solid waste falling on the top of the pressure plate 11, thereby preventing solid waste from accumulating on the top of the pressure plate 11.

[0025] Example 4

[0026] like Figure 2 As shown, in order to solve the problem that it is not easy to automatically control the motor 5 to stop when the force of pressing down solid waste is large, the top of the outer side of the fixing rod 9 is provided with a spring 14 and a sliding plate 15 arranged vertically, and the sliding plate 15 is in contact with the slider 7. The sliding plate 15 is fixedly connected to the fixing rod 9, and the bottom end of the spring 14 is in contact with the sliding plate 15. The top of the fixing rod 9 is fixedly connected to a second control switch 16. When the force of pressing down solid waste is large, the fixing rod 9 drives the sliding plate 15 to compress the spring 14 and trigger the second control switch 16, which facilitates the automatic control of the motor 5 to stop.

[0027] Example 5

[0028] like Figure 1-2 As shown, in order to solve the problem that the spring 14 is inconvenient to replace after long-term use, the top of the spring 14 is in contact with a threaded plug 17, and the threaded plug 17 is screwed to the slider 7. After the spring 14 has been used for a long time, the threaded plug 17 can be rotated to disengage from the slider 7, making it convenient to take out the spring 14 for replacement.

[0029] In this embodiment, when crushing some non-metallic, relatively loose, lightweight solid waste using the device, the device is started by the controller 19. At this time, the conveyor 3 continuously transports the solid waste to the fixed cover 2 at the top of the feed hopper of the waste crushing equipment 1. Then, the motor 5 drives the threaded shaft 6 to connect with the slider 7. The slider 7 drives the pressure plate 11 to move downward through the fixed rod 9 and the fixed seat 10. As the pressure plate 11 moves downward, in conjunction with the spring force of the spring spring 13 on the left fixed shaft 12 of the pressure plate 11, the pressure plate 11 will first rotate to a horizontal position and contact the fixed seat 10. Then, as the slider 7 drives the pressure plate 11 to continue moving downward through the fixed rod 9 and the fixed seat 10, the pressure plate 11... The conveying non-metallic lightweight solid waste is pressed down by the pressure plate 11. As the solid waste is continuously pressed down by the pressure plate 11, when the force of the pressure plate 11 pressing the non-metallic lightweight solid waste is large, the fixing rod 9 will start to continuously drive the slide plate 15 to compress the spring 14. The waste will be continuously crushed by the waste crushing device 1. When the fixing rod 9 drives the slide plate 15 to compress the spring 14 and triggers the second control switch 16, the motor 5 stops. When the second control switch 16 is no longer triggered by the fixing rod 9 due to the elastic force of the spring 14 on the slide plate 15, the motor 5 restarts and continues to control the pressure plate 11 to press down the solid waste. When the waste pressed down by the pressure plate 11 is completely crushed, at this time... After sliding down, slider 7 triggers the first control switch 8 at the bottom, and then the controller 19 automatically controls motor 5. Motor 5 starts to reverse and reset slider 7 and pressure plate 11. During the upward reset of slider 7 and pressure plate 11, when pressure plate 11 is just reset to the top of conveyor 3, as pressure plate 11 continues to reset upward, the magnetic plates 18 at the top of pressure plate 11 and the inner top of the fixed cover 2 repel each other, and pressure plate 11 starts to tilt, driving fixed shaft 12 to rotate. The spring 13 will continuously contract, and the solid waste conveyed on top of pressure plate 11 will continuously slide down the tilted pressure plate 11. When the first control switch 8 is reset to the trigger top, the controller 19 will control the motor 5 to rotate forward again and repeat the above operation. At this time, by controlling the reciprocating motion of the pressure plate 11, some non-metallic and relatively loose light solid waste is pressed down to reduce the space occupied when it is conveyed into the feed hopper of the waste crushing equipment 1, thereby speeding up the feeding speed and increasing the overall solid waste processing capacity. During the use of the device, the spring 14 may undergo fatigue deformation after long-term use, so it needs to be replaced regularly. At this time, the spring 14 can be removed and replaced by rotating the threaded plug 17 to disengage it from the slider 7.
