[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Refer to Figures 1-3 , a screw feeder cleaning device, including the main body 1 of the screw feeder, a plugging component 2, a cleaning component 3 and a discharge component 4. The plugging component 2 is arranged on the main body 1 of the screw feeder, and the plugging component 2 performs a closing treatment on the top of the main body 1 of the screw feeder. The cleaning component 3 is arranged on the main body 1 of the screw feeder, and the cleaning component 3 flushes the screw blades inside the main body 1 of the screw feeder. The discharge component 4 is arranged at the bottom of the main body 1 of the screw feeder, and the discharge component 4 facilitates the discharge of sewage inside the main body 1 of the screw feeder;

[0027] The plugging component 2 includes an upper clamping plate 21 detachably connected to the spiral feeder body 1. A lower clamping plate 22 is fixedly connected to the bottom of the upper clamping plate 21. Both the upper clamping plate 21 and the lower clamping plate 22 are arranged in an arc shape. A groove 23 is formed at the top of the spiral feeder body 1. A sleeve 24 is fixedly connected to the upper clamping plate 21. There are four sleeves 24, and the four sleeves 24 are evenly distributed at the four corners of the upper clamping plate 21. A self-tapping screw 25 threadedly penetrates through the sleeve 24. After the self-tapping screw 25 threadedly penetrates through the sleeve 24 and the upper clamping plate 21, it is connected to the spiral feeder body 1. The self-tapping screw 25 is threadedly connected to the spiral feeder body 1. A chute 26 is formed in the spiral feeder body 1 through the groove 23. There are two chutes 26, and the two chutes 26 are symmetrically distributed with the central axis of the upper clamping plate 21 as the center. An elastic plate 27 is slidably connected to the inside of the spiral feeder body 1. The inner circumference of the chute 26 is equal to the outer circumference of the elastic plate 27. A spring 28 is fixedly connected to the bottom of the elastic plate 27. The spring 28 is fixedly connected to the spiral feeder body 1. A pressing plate 29 is fixedly connected to the bottom of the upper clamping plate 21. There are two pressing plates 29, and the two pressing plates 29 are symmetrically distributed with the central axis of the upper clamping plate 21 as the center. The pressing plate 29 is in close contact with the elastic plate 27. After the self-tapping screw 25 rotates and moves to be separated from the spiral feeder body 1, the upper clamping plate 21 and the sleeve 24, the spring 28 changes from the compressed state to the initial state. The spring 28 bounces upward, and the pressing plate 29 receives an upward acting force. The upper clamping plate 21 moves upward accordingly, so that the outer wall of the upper clamping plate 21 and the outer wall of the spiral feeder body 1 are no longer in the same state, facilitating the cleaning personnel to move the upper clamping plate 21 to be separated from the spiral feeder body 1.

[0028] Referring to Figure 3 , a fitting groove 210 is formed in the spiral feeder body 1 through the groove 23. The fitting groove 210 is adapted to the pressing plate 29. The inner circumference of the fitting groove 210 is equal to the outer circumference of the pressing plate 29. The fitting groove 210 facilitates the fitting between the pressing plate 29 and the spiral feeder body 1.

[0029] Referring to Figure 4 , the cleaning component 3 includes a mounting plate 31 fixedly connected to the outer wall of the spiral feeder body 1. A top frame 32 is fixedly connected to the mounting plate 31. An adjustment groove 33 is formed inside the top frame 32. A slider 34 is slidably connected to the top frame 32 through the adjustment groove 33. The mounting plate 31, the top frame 32 and the adjustment groove 33 facilitate the slider 34 to be mounted above one side of the spiral feeder body 1 without affecting the installation and disassembly of the upper clamping plate 21.

[0030] Referring to Figure 4, a transfer pipe 35 is fixedly connected inside the slider 34, and the transfer pipe 35 is arranged in an inclined shape. The inclined end of the transfer pipe 35 is fixedly connected with a spray head 36. One end of the transfer pipe 35 far from the spray head 36 is communicated with a water delivery pipe. After water moves into the interior of the transfer pipe 35 through the water delivery pipe, it is sprayed obliquely through the spray head 36 onto the spiral blades inside the spiral feeder body 1, thereby flushing the spiral blades.

[0031] Refer to Figure 4 , an electric telescopic rod 37 is fixedly connected to the top frame 32. The telescopic end of the electric telescopic rod 37 is fixedly connected with the slider 34. After the electric telescopic rod 37 operates, the slider 34 moves obliquely accordingly, adjusting the position of the spray head 36.

[0032] Refer to Figures 1-2 , the discharge assembly 4 includes a discharge pipe 41 fixedly communicated with the bottom of the spiral feeder body 1. A closing cover 43 is threadedly connected to the bottom of the discharge pipe 41. The outer side of the bottom of the discharge pipe 41 is adapted to the inner side wall of the closing cover 43, and the closing cover 43 plugs the bottom of the discharge pipe 41.

[0033] Refer to Figures 1-2 , a filling rod 42 is fixedly connected inside the closing cover 43. The filling rod 42 is made of rubber material and has a certain elasticity. The outer side wall of the filling rod 42 is in close contact with the inner side wall of the discharge pipe 41. The filling rod 42 plugs the interior of the discharge pipe 41 to prevent the materials inside the spiral feeder body 1 from flowing into the interior of the discharge pipe 41. The motor installed on the spiral feeder body 1 is a forward and reverse rotation motor. After the spiral blades are driven to rotate in the reverse direction by the forward and reverse rotation motor, the sewage inside the spiral feeder body 1 is discharged through the discharge pipe 41.

[0034] Working principle: When it is necessary to clean the spiral blades inside the spiral feeder body 1, the self-tapping screw 25 rotates upward and moves away from the sleeve 24. The spring 28 changes from the compressed state to the initial state, and the elastic plate 27 pops up upward. The elastic plate 27 ejects the pressure plate 29, causing the upper clamping plate 21 to pop up upward, so as to facilitate removing the upper clamping plate 21 from the spiral feeder body 1, and then it is convenient to block or open the outside of the spiral feeder body 1. One end of the transfer pipe 35 far from the spray head 36 is communicated with a water delivery pipe. Water is transmitted into the interior of the transfer pipe 35 through the water delivery pipe and sprayed out through the spray head 36 to flush the spiral blades inside the spiral feeder body 1. The electric telescopic rod 37 operates, and the slider 34 drives the spray head 36 to move to evenly flush the spiral blades inside the spiral feeder body 1. The motor on the spiral feeder body 1 drives the spiral blades to rotate in the reverse direction, and the closing cover 43 drives the filling rod 42 to move away from the discharge pipe 41. The sewage generated by flushing inside the spiral feeder body 1 is discharged through the discharge pipe 41, thereby flushing the spiral blades inside the spiral feeder body 1.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
