[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model.

[0026] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown in the illustration, a bottom lifting and cleaning mechanism for a hopper, comprising a hopper 1 and a cleaning and lifting support 2 disposed at the bottom of the hopper 1, wherein the cleaning and lifting support 2 includes a water inlet pipe 21 and a spray frame, one end of the water inlet pipe 21 being connected to an external water source and the other end being connected to the spray frame.

[0028] It also includes a lifting drive mechanism for raising and lowering the cleaning and lifting bracket 2.

[0029] The spray frame includes an external cleaning pipe 22 and an internal cleaning pipe 23 that are connected to each other. The external cleaning pipe 22 surrounds the outside of the hopper 1 and is parallel to the lower port of the hopper 1. The external cleaning pipe 22 is connected to a plurality of external nozzles 3. The internal cleaning pipe 23 is opposite to the lower port of the hopper 1 and is vertically arranged. The internal cleaning pipe 23 is connected to an internal nozzle 4.

[0030] With this setup, the inner cleaning pipe sprays water into the hopper, while the outer cleaning pipe sprays water into the hopper. The two work together to clean the hopper efficiently and comprehensively. At the same time, the lifting drive mechanism drives the cleaning lifting bracket to move up and down, so that the inner and outer nozzles can move closer to or further away from the hopper. The lifting is stable and precise, solving the problem of cleaning the valve plate with a complex baffle structure at the bottom of the hopper and the valve plate with an automatic valve opening structure at the bottom of the hopper.

[0031] The cleaning and lifting support 2 also includes a fixed support 24. The fixed support 24 includes connecting vertical rods 241 located on both sides of the hopper 1 and a connecting horizontal rod 242 connected between the two connecting vertical rods 241 and located below the hopper 1. The external cleaning pipe 22 is fixed on the connecting horizontal rod 242. A driving horizontal part 243 is provided at the upper end of the connecting vertical rod 241. There are two lifting drive mechanisms, which are respectively located on one side of the corresponding connecting vertical rod 241. The driving end of the lifting drive mechanism is connected to the driving horizontal part 243.

[0032] This design reduces the space occupied by the lifting mechanism of the device. At the same time, the two lifting drive mechanisms work together to lift the cleaning support, which improves the stability of the lifting process.

[0033] It also includes a support platform 5 for placing the hopper 1. A vertically arranged positioning rod 51 is installed at the bottom of the support platform 5. A positioning block 52 is installed on the connecting crossbar 242 corresponding to the position of the positioning rod 51. The positioning block 52 is provided with a positioning hole 53 that is adapted to the shape of the positioning rod 51 and allows it to pass through to form a fit.

[0034] With this setting, the positioning hole and the positioning rod work together to restrict the radial movement of the positioning rod during the lifting process, thereby improving the stability of the cleaning lifting bracket and making the working positions of the inner and outer nozzles more precise.

[0035] The external nozzle 3 includes a connecting cylinder 31 and a main injection pipe 32 installed at the center of the connecting cylinder 31. The main injection pipe 32 divides the inner cavity of the connecting cylinder 31 into an injection channel 33 formed in the inner cavity of the main injection pipe 32 and an injection annular channel 34 located between the outer periphery of the injection channel 33 and the inner periphery of the connecting cylinder 31. A diffuser cone 321 is connected to the outer periphery of the upper end of the main injection pipe 32. The diameter of the outer peripheral surface of the diffuser cone 321 increases from the lower end to the upper end.

[0036] With this setup, the water entering the connecting cylinder from the side spray frame is dispersed by the main spray pipe into the spray channels and spray ring channels. The water in the spray ring channels diffuses outward through the diffuser cone to form a larger spray surface. The spray channels located in the center ensure that the water in the center is concentrated, thus achieving full coverage cleaning of the hopper.

[0037] The central screw hole of the diffuser cone 321 is rotatably engaged with the outer circumferential thread of the main injection pipe 32.

[0038] This setting allows for adjustment of the axial position of the diffuser cone connected to the main spray pipe by rotating it, thereby adjusting the area of ​​the spray surface formed by the diffuser cone and adapting it to hoppers of various sizes, thus improving the flexibility of adjustment.

[0039] The inner circumference of the connecting cylinder 31 is provided with a connecting ring 311, the inner circumference of the connecting ring 311 is threadedly connected to the outer circumference of the main jet pipe 32, and the connecting ring 311 is provided with a plurality of water outlet holes 312 along its axial direction.

[0040] This design facilitates the easy assembly and disassembly of the main jet pipe and ensures reliable connection. The connecting ring is equipped with a water outlet hole, which does not affect the water output of the jet ring channel.

[0041] The lifting drive mechanism includes a vertically arranged cylinder 61 and a cylinder cover 62 covering the cylinder 61.

[0042] This setting improves the stability of cylinder operation.

[0043] The external cleaning pipeline 22 is connected to the water inlet pipe 21 via a connecting hose 25.

[0044] This setup ensures that the connecting hose maintains a proper connection with the inlet pipe during the raising and lowering of the external cleaning pipeline.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
