[0036] Example 2
[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0038] Specifically, the sludge discharge component 26 includes a sludge inlet pipe 26-1 connected to one side of the gathering frame 21, a sleeve 26-2 connected to one side of the sludge inlet pipe 26-1, a sludge discharge pipe 26-3 connected to the bottom of the sleeve 26-2, and a one-way valve 26-4 provided on one side of both the sludge inlet pipe 26-1 and the sludge discharge pipe 26-3.
[0039] The sludge discharge component 26, through the combination of sludge inlet pipe 26-1, sleeve 26-2, sludge discharge pipe 26-3 and one-way valve 26-4, realizes the one-way intake and discharge of sludge. Sludge inlet pipe 26-1 introduces the sludge in the collection frame 21 into sleeve 26-2. One-way valve 26-4 ensures that the sludge can only flow in one direction to avoid backflow. Sludge discharge pipe 26-3 discharges the sludge in sleeve 26-2, making the sludge cleaning process more orderly and controllable.
[0040] Specifically, a pneumatic push rod 26-5 is provided on one side of the sleeve 26-2. One side of the pneumatic push rod 26-5 passes through the sleeve 26-2 and is fixedly connected to a piston 26-6. The piston 26-6 contacts the inner wall of the sleeve 26-2.
[0041] The pneumatic push rod 26-5 and piston 26-6 provide a power source for the sludge discharge component 26. The pneumatic push rod 26-5 pushes the piston 26-6 to move within the sleeve 26-2, generating negative or positive pressure, thereby realizing the intake and discharge of sludge, enhancing the automation of the sludge discharge process and reducing manual operation.
[0042] Specifically, a support plate 26-7 is fixedly connected to the other side of the pneumatic push rod 26-5. The support plate 26-7 contacts the bottom of the sleeve 26-2. Connecting rods 26-8 are fixedly connected to all four sides of the support plate 26-7. The connecting rods 26-8 are fixedly connected to the bottom of the cleaning machine 11.
[0043] The support plate 26-7 and connecting rod 26-8 provide a stable support structure for the pneumatic push rod 26-5, ensuring that the pneumatic push rod 26-5 remains stable during operation, so that the piston 26-6 can reliably reciprocate within the sleeve 26-2, ensuring the smooth progress of sludge discharge.
[0044] Specifically, the purification component 27 includes a purification pipe 27-1 connected to the other side of the gathering frame 21. The bottom of the purification pipe 27-1 is connected to a box 27-2. One side of the box 27-2 is fixedly connected to the gathering frame 21. A filter plate 27-3 is provided in the inner cavity of the box 27-2. A drain pipe is connected to the bottom of the box 27-2.
[0045] The cleaning mud and water generated is purified through the purification pipe 27-1, the housing 27-2 and the filter plate 27-3 in the purification component 27. The mud and water enter the housing 27-2 through the purification pipe 27-1, and after being filtered by the filter plate 27-3, the clean water is discharged from the drain pipe, effectively separating the mud and water and preventing mud particles from entering the sewer and causing blockage.
[0046] Specifically, one side of the rotating shaft 24 passes through the cleaning machine 11 and the housing 27-2, and is fixedly connected to the driving bevel gear 27-4. One side of the driving bevel gear 27-4 is meshed with the driven bevel gear 27-5. The inner cavity of the driven bevel gear 27-5 is fixedly connected to the swing shaft 27-6. Both sides of the swing shaft 27-6 are rotatably connected to the inner cavity of the housing 27-2 through bearings. The surface of the swing shaft 27-6 is provided with a vibration part 27-7.
[0047] The rotating shaft 24 drives the driving bevel gear 27-4, the driven bevel gear 27-5, and the swing shaft 27-6 to rotate, transmitting the power of the drive motor 23 to the vibration part 27-7, providing a power source for the vibration of the filter plate 27-3, so that the filter plate 27-3 remains in a vibrating state during operation and prevents clogging.
[0048] Specifically, the vibrating part 27-7 includes cams 27-71 fixedly connected to both sides of the surface of the swing shaft 27-6. Each side of the cams 27-71 is provided with a movable rod 27-72. A slider 27-73 is fixedly connected to one side of the movable rod 27-72. A slide block 27-74 is slidably connected to the surface of the slider 27-73. The slide block 27-74 is fixedly connected to the inner cavity of the housing 27-2. A lifting rod 27-75 is fixedly connected to the top of the slider 27-73. The top of the lifting rod 27-75 passes through the slide block 27-74 and extends to the bottom of the filter plate 27-3.
[0049] The cam 27-71, movable rod 27-72, slider 27-73, slide block 27-74 and lifting rod 27-75 of the vibrating part 27-7 work together to convert the rotation of the swing shaft 27-6 into the up and down movement of the lifting rod 27-75, thereby driving the filter plate 27-3 to vibrate, effectively preventing the filter plate 27-3 from being clogged by impurities due to long-term use.
[0050] Specifically, a first spring 27-76 is fixedly connected to the top of the movable rod 27-72, a fixed seat 27-77 is fixedly connected to the top of the first spring 27-76, and one side of the fixed seat 27-77 is fixedly connected to the slide 27-74.
[0051] The first spring 27-76 provides a restoring force to the movable rod 27-72. When the cam 27-71 moves away from the movable rod 27-72, the first spring 27-76 returns to its original position, so that the movable rod 27-72, the slider 27-73 and the lifting rod 27-75 return to their initial positions, ensuring that the vibrating part 27-7 can work continuously and stably.
[0052] Specifically, a second spring 27-31 is fixedly connected to both sides of the top of the filter plate 27-3, and a mounting plate 27-32 is fixedly connected to the top of the second spring 27-31. The mounting plate 27-32 is fixedly connected to the inner cavity of the housing 27-2.
[0053] The second spring 27-31 connects the filter plate 27-3 and the mounting plate 27-32. It acts as a buffer when the filter plate 27-3 is impacted by the lifting rod 27-75, while also enhancing the vibration effect of the filter plate 27-3, thereby improving filtration efficiency and service life.
[0054] Specifically, there are multiple sets of second springs 27-31, which are evenly distributed on the bottom of mounting plates 27-32.
[0055] Multiple sets of second springs 27-31 evenly distributed at the bottom of the mounting plate 27-32 can provide more uniform buffering and vibration assistance to the filter plate 27-3, so that the filter plate 27-3 can get good vibration effect in all positions, further improving the filtration performance.
[0056] In use, the chives are placed on the conveyor belt 13 and rinsed by water spraying through the nozzle 12. The mud and water mix to form mud slurry. Inside the cleaning machine 11, the gathering plate 22 gathers the mud slurry towards the screw conveyor 25. The drive motor 23 drives the rotating shaft 24 and the screw conveyor 25 to rotate, transporting the mud slurry to the gathering frame 21. Then, the pneumatic push rod 26-5 is activated, and the piston 26-6 moves inside the sleeve 26-2 to generate negative pressure. The one-way valve 26-4 on the mud inlet pipe 26-1 opens, and the sludge is sucked into the sleeve 26-2. Subsequently, when the piston 26-6 moves in the reverse direction, the one-way valve 26-4 on the mud discharge pipe 26-3 opens, and the sludge is discharged through the mud discharge pipe 26-3. This overcomes the problem in the prior art that the mud slurry formed by the mixture of mud and water accumulates in the mud removal device, making the cleaning work extremely difficult.
[0057] Meanwhile, the muddy water generated during washing enters the housing 27-2 through the purification pipe 27-1, is filtered by the filter plate 27-3, and then discharged. The rotating shaft 24 drives the active bevel gear 27-4, the driven bevel gear 27-5, the swing shaft 27-6, and the cam 27-71 to rotate. The cam 27-71 pushes the movable rod 27-72, causing the slider 27-73 to slide within the slide block 27-74 and stretching the first spring 27-76. When the cam 27-71 moves away from the movable rod 27-72, the first spring 27-76 returns to its original position, causing the lifting rod 27-75 to move and impact the filter plate 27-3. The second spring 27-31 acts as a buffer and enhances the vibration effect. The muddy water is fully filtered under the vibration of the filter plate 27-3, and the clean water is discharged from the drain pipe. The entire process achieves mud removal from the chives, sludge cleaning, and muddy water purification, solving the problems existing in current devices.
[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
