[0041] The cleaning box 3, the water tank 4 and the blower 5 are all located below the conveyor belt 1 and are arranged in sequence.

[0042] The cleaning mechanism includes:

[0043] A rotating shaft 31 rotatably connected inside the cleaning box 3. A plurality of groups of brushes 32 are fixedly connected to the rotating shaft 31. One end of the brush 32 away from the rotating shaft 31 extends outside the cleaning box 3 and contacts the surface of the conveyor belt 1 for cleaning the conveyor belt 1.

[0044] The cleaning mechanism includes:

[0045] A water pump 44, fixedly connected to the water tank 4. The output end of the water pump 44 is connected to a water spray pipe 45, and one end of the water spray pipe 45 away from the water pump 44 faces the surface of the conveyor belt 1 for cleaning the surface of the conveyor belt 1;

[0046] The top of the water tank 4 is open. A partition 41 is fixedly connected to the water tank 4. The partition 41 divides the water tank 4 into a water storage cavity and a water receiving tray. The input end of the water pump 44 is connected to a water suction pipe 46, and the water suction pipe 46 is communicated with the water storage cavity.

[0047] A scraper 42 is fixedly connected to the water tank 4. The top end of the scraper 42 is attached to the surface of the conveyor belt 1, and is used to scrape off the water droplets adhering to the surface of the conveyor belt 1.

[0048] An air inlet 33 is opened on the cleaning box 3. The air inlet 33 is inclined towards the surface of the conveyor belt 1. A first air duct 6 is communicated with the cleaning box 3. One end of the first air duct 6 away from the cleaning box 3 is communicated with the water storage cavity. The end of the first air duct 6 communicated with the water storage cavity is in an inverted U shape, and its opening is close to the bottom of the water storage cavity. A flow limiting hole 61 is opened on the first air duct 6, and the flow limiting hole 61 is close to the bottom of the water receiving tray.

[0049] A second air duct 7 is provided on one side of the water tank 4 away from the first air duct 6. The second air duct 7 is communicated with the water storage cavity, and the communication part is located at the top of the water storage cavity. A filter screen 43 is fixedly connected in the water storage cavity. The filter screen 43 divides the water storage cavity into a first chamber and a second chamber. The water suction pipe 46 and the second air duct 7 are communicated with the first chamber, and the first air duct 6 is communicated with the second chamber.

[0050] One end of the second air duct 7 away from the water tank 4 is connected to the suction input end of the blower 5.

[0051] A sewage outlet 47 and a water filling port 48 are fixedly connected to the bottom of the water tank 4. The water filling port 48 is communicated with the first chamber, and the sewage outlet 47 is communicated with the second chamber.

[0052] A motor 11 is fixedly connected to the frame 2. The output end of the motor 11 is fixedly connected to the conveyor roller 12. When the motor 11 works, it drives the conveyor roller 12 to rotate, and further drives the conveyor belt 1 to convey traditional Chinese medicine pieces or traditional Chinese medicine.

[0053] A driving guide wheel 13 is fixedly connected to one end of the conveyor roller 12. A driven guide wheel 34 is fixedly connected to one end of the rotating shaft 31. The driving guide wheel 13 is rotationally connected to the driven guide wheel 34 through a transmission belt 35. When the conveyor roller 12 rotates, it will drive the driving guide wheel 13 to rotate, and further drive the driven guide wheel 34 to rotate through the transmission belt 35, so as to drive the rotating shaft 31 to rotate.

[0054] During the operation of this mechanism, the conveyor belt 1 rotates to transport the traditional Chinese medicine pieces or traditional Chinese medicine placed thereon. The transportation direction is from the direction away from the cleaning box 3 towards the cleaning box 3. When the traditional Chinese medicine pieces or traditional Chinese medicine on the conveyor belt 1 are transported above the cleaning box 3, they are taken away by the staff. The dust generated during the transportation of the traditional Chinese medicine pieces or traditional Chinese medicine will accumulate and adhere to the conveyor belt 1. As the conveyor belt 1 continues to operate, the conveyor belt 1 with accumulated and adhered dust will rotate towards the cleaning box 3. Synchronously, the rotating shaft 31 in the cleaning box 3 will continuously rotate under the transmission of the driving guide wheel 13, the transmission belt 35, and the driven guide wheel 34, thereby driving the brush 32 thereon to rotate rapidly around the rotating shaft 31, so as to clean the conveyor belt 1 in contact with the brush 32 and remove the accumulated and adhered dust thereon. At the same time, the negative pressure in the cleaning box 3 will suck the external air through the air inlet 33, and then the dust swept and fallen by the brush 32 can be collected and sucked, and transported towards the blower 5 along the first air duct 6;

[0055] When the conveyor belt 1 with adhered dust continues to move above the water tank 4, the water pump 44 will extract the clear water in the first chamber through the water suction pipe 46 and spray it through the water spray pipe 45, so as to clean the surface of the conveyor belt 1, and the purpose of further removing the dust on the surface of the conveyor belt 1 can be achieved. The cleaning sewage will fall into the water receiving tray under the action of its own weight, and the scraper 42 will scrape off the water droplets adhered to the surface of the conveyor belt 1 to reduce the residual water stains adhered to the conveyor belt 1;

[0056] When the conveyor belt 1 with residual water stains moves above the blower 5, the blower 5 operates to suck the air in the second air duct 7 and quickly eject it through the air jet pipe 51, thereby drying the residual water stains on the surface of the conveyor belt 1. It should be noted that the blower 5 is internally provided with a heating wire to heat the ejected air, so as to improve the drying efficiency and ensure that the conveyor belt 1 with residual water stains is fully dried after moving above the blower 5, facilitating the continuous transportation of traditional Chinese medicine pieces or traditional Chinese medicine. After the blower 5 extracts the air in the second air duct 7, the second air duct 7 will be in a negative pressure state, and then the air at the top of the first chamber will be extracted through the end of the second air duct 7 far away from the blower 5, making the first chamber in a negative pressure state. One end of the first air duct 6 far away from the water tank 4 is connected to the external air through the air inlet 33 of the cleaning box 3. Thus, under the action of the internal and external atmospheric pressure difference, the air in the first air duct 6 can be sucked in, and then the mixed gas formed by the dust cleaned in the cleaning box 3 and the external air is sucked into the second chamber through the first air duct 6. The water liquid in the second chamber can adsorb the dust in the mixed gas, making the clean air float in the form of bubbles to the air at the top of the second chamber. This part of the air passes through the filter screen 43 for secondary filtration and enters the top of the first chamber, and then is extracted by the second air duct 7 and conveyed into the blower 5 to dry the conveyor belt 1; synchronously, the sewage falling into the water receiving tray will be sucked into the second chamber through the flow limiting hole 61 under the action of the negative pressure in the first air duct 6 to achieve the purpose of collecting sewage. The sewage entering the second chamber will be filtered by the filter screen 43 and enter the first chamber in a clear water state, facilitating the continuous extraction of the water pump 44, and thus facilitating the continuous cleaning of the surface of the conveyor belt 1.

[0057] When the dust content in the sewage in the second chamber is too high, it may affect the filtering efficiency of the filter screen 43, resulting in the clear water entering the first chamber through the filter screen 43 not being sufficient for the extraction and use of the water pump 44. At this time, the conveyor belt 1 can be paused. First, open the sewage discharge port 47 to discharge the sewage collected in the second chamber, and then open the water filling port 48. Through an external water pipe, clear water is filled into the first chamber through the water filling port 48. The clear water entering the first chamber will reversely pass through the filter screen 43 and enter the second chamber, so as to achieve the purpose of backwashing the filter screen 43. The sewage after washing is discharged through the sewage discharge port 47. When the turbidity of the discharged sewage is significantly reduced, then close the sewage discharge port 47, refill the storage cavity with clear water through the water filling port 48 until the liquid level in the storage cavity is close to its top (the liquid level cannot contact the top of the storage cavity), and then close the water filling port 48 to stop filling clear water. Then control the conveyor belt 1 to continue working. In this way, the dust accumulated and attached to the surface during the transportation of traditional Chinese medicine pieces or traditional Chinese medicine by the conveyor belt 1 can be continuously removed, avoiding the dust accumulated on the surface of the conveyor belt 1 from spreading into the air, polluting the working environment of the hospital, and affecting the health of employees.

[0058] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and should not be considered as limiting the scope of implementation of the present utility model. Any equivalent changes and improvements made within the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
