The outer cylinder 2 is arranged on the frame 1 in a rotating connection manner, and the outer cylinder 2 can rotate in the circumferential direction relative to the frame 1. One end of the outer cylinder 2 is configured as a feeding port 6 for input of traditional Chinese medicinal materials, and the other end of the outer cylinder 2 is configured as a discharging port 7 for output of traditional Chinese medicinal materials. The cleaning water pipe 9 is arranged on the inner side wall of the outer cylinder 2, and the arrangement direction of the cleaning water pipe 9 is consistent with the axial direction of the outer cylinder 2, and the cleaning water pipe 9 is arranged along the axial direction of the outer cylinder 2. The plurality of sprayers 10 are installed on the cleaning water pipe 9, and the plurality of sprayers 10 can spray water to the inside of the outer cylinder 2 from multiple directions, so as to ensure that different areas inside the outer cylinder 2 can be effectively sprayed.

[0031] The inner cylinder 3 is arranged in the inner space of the outer cylinder 2, and the inner cylinder 3 can be arranged in the embedded manner to form an assembly relationship with the outer cylinder 2. A plurality of water permeable holes 8 are arranged on the surface wall of the inner cylinder 3, and the plurality of water permeable holes 8 are regularly or irregularly distributed to achieve a specific water permeable function. One end of the inner cylinder 3 is in communication with the feeding port 6 of the outer cylinder 2, and the other end of the inner cylinder 3 is in communication with the discharging port 7 of the outer cylinder 2, so as to form a complete flow path of the material entering the inner cylinder 3 through the feeding port 6, being processed in the inner cylinder 3, and being discharged through the discharging port 7. The conveying blade 4 is arranged along the axial direction of the inner cylinder 3, and the conveying blade 4 can be stably arranged on the inner wall of the inner cylinder 3 by welding, bolt connection or other suitable fixing methods. The conveying blade 4 can efficiently drive the traditional Chinese medicinal materials in the inner cylinder 3 to move in a specific direction.

[0032] The water supply assembly is an independent functional unit, and its core function is to provide a stable water source for the cleaning water pipe 9, so as to ensure that the water flow can be continuously and accurately injected into the cleaning water pipe 9, and meet the demand of the cleaning operation on the water quantity and water pressure.

[0033] The driving assembly is the power core unit of the device, and is designed to provide power for the outer cylinder 2, so that the outer cylinder 2 can rotate in the circumferential direction. The rotation of the outer cylinder 2 drives the inner cylinder 3 associated therewith to rotate synchronously, and then drives the conveying blade 4 arranged on the inner wall of the inner cylinder 3 to rotate, so as to realize efficient conveying of the traditional Chinese medicinal materials in the inner cylinder 3. At the same time, the plurality of nozzles 10 arranged on the cleaning water pipe 9 can realize multi-directional water spraying due to the rotation of the outer cylinder 2 and the specific layout thereof, so as to ensure that the materials in the outer cylinder 2 and the inner cylinder 3 can be covered by the cleaning liquid at different angles, and meet the dual functional demand of the device on the material cleaning and conveying.

[0034] Working principle: in the operation process of the traditional Chinese medicinal material cleaning device, the operator first places the traditional Chinese medicinal materials to be cleaned in the inner space of the inner cylinder 3 through the feeding port 6. Then, the water supply assembly is started to spray water to the inner cylinder 3, and the sprayed water flow enters the inner cylinder 3 through the plurality of water permeable holes 8 arranged on the surface wall of the inner cylinder 3, and then the traditional Chinese medicinal materials in the cylinder are preliminarily cleaned.

[0035] Subsequently, the driving assembly is started to drive the outer cylinder 2 to rotate in the circumferential direction on the rack 1 by the mechanical transmission mode. Since the outer cylinder 2 and the inner cylinder 3 have associated structures, the rotation of the outer cylinder 2 drives the inner cylinder 3 to rotate synchronously, and the conveying blade 4 arranged on the inner wall of the inner cylinder 3 rotates. In this process, the conveying blade 4 drives the traditional Chinese medicinal materials in the inner cylinder 3 to be continuously conveyed along the axial direction of the inner cylinder 3.

[0036] At the same time, the rotation of the outer cylinder 2 drives the synchronous rotation of the cleaning water pipe 9 connected thereto, and further drives the rotation of the plurality of spray heads 10 mounted on the cleaning water pipe 9 along the circumferential direction of the outer cylinder 2. During the rotation of the spray heads 10, the spray heads 10 can perform water spraying on the Chinese herbal medicines in the inner cylinder 3 from different directions, effectively reducing the possible cleaning dead angle in the cleaning process of the Chinese herbal medicines, significantly improving the cleaning degree of the Chinese herbal medicines, and meeting the high-quality requirement of the Chinese herbal medicine cleaning process.

The water pump is used to increase the water flow pressure to meet the water pressure requirement of the cleaning operation. One end of the delivery pipe 19 is in communication with the cleaning water pipe 9, and the other end of the delivery pipe 19 is assembled in a rotatable connection manner with the water outlet pipe 16. In this connection structure, the delivery pipe 19 takes the connection part between the delivery pipe 19 and the water outlet pipe 16 as the rotation fulcrum, and during the operation of the equipment, the delivery pipe 19 can rotate synchronously with the cleaning water pipe 9, ensuring that the water in the water supply source box 5 can be stably and continuously delivered to the cleaning water pipe 9 through the delivery pipe 19 while the cleaning water pipe 9 rotates with the outer cylinder 2, thereby providing reliable water supply guarantee for the cleaning function of the equipment.

The gear ring 13 is annularly arranged outside the outer cylinder 2 and tightly adheres to the outer cylinder 2, and the relative positions of the two are fixed. The drive gear 12 and the gear ring 13 are precisely designed to be meshed with each other. When the motor 11 drives the drive gear 12 to rotate, the teeth of the drive gear 12 and the teeth of the gear ring 13 interact with each other, and the rotational motion of the drive gear 12 is smoothly transmitted to the gear ring 13, thereby driving the outer cylinder 2 connected thereto to rotate along the circumferential direction of its own axis, providing reliable power support for the rotation function of the outer cylinder 2 of the equipment, and ensuring the stability and accuracy of power transmission during equipment operation.

[0041] In some embodiments of the present application, during long-term operation of the equipment, sewage generated during the cleaning process will gradually accumulate inside the outer cylinder 2 due to continuous cleaning of traditional Chinese medicinal materials. Therefore, the outer wall of the outer cylinder 2 is pre-provided with a sewage discharge port, and a sewage cover is detachably connected to the sewage discharge port. The connection mode can be selected from threaded connection, buckle connection or flange connection, etc., to ensure that the sewage cover can tightly adhere to the sewage discharge port after installation, thereby achieving good sealing performance and effectively preventing leakage of sewage in the outer cylinder 2.

The rotating ring 14 on the outer cylinder 2 is precisely installed between the two rotating wheels 15, and the rotating ring 14 can be flexibly rotated between the two rotating wheels 15, thereby driving the outer cylinder 2 to rotate around its axis. In order to ensure the stability of the rotating ring 14 during rotation and prevent the rotating ring 14 from deviating relative to the rotating wheel 15, a protruding structure 20 is specially provided on both sides of the rotating wheel 15. The protruding structure 20 surrounds the edge of the rotating wheel 15, forming a limiting constraint for the rotating ring 14, so that the rotating ring 14 is stably limited in the rotating wheel 15, ensuring that the rotating ring 14 always maintains the preset motion track during the long-time operation of the outer cylinder 2, and maintaining the stability and reliability of the equipment operation.
