Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal material cleaning technology, and in particular to a Chinese medicinal material pretreatment device. Background Technology

[0002] After harvesting, Chinese medicinal herbs often contain mud, impurities, and some surface residue, especially root and rhizome herbs such as Astragalus membranaceus, Codonopsis pilosula, and Angelica sinensis. Their uneven surfaces easily trap dirt and grime. Therefore, they must be thoroughly cleaned before entering the subsequent processing steps. Currently, traditional Chinese medicinal herb cleaning methods mostly involve manual brushing or simple water immersion rinsing, which are inefficient, labor-intensive, and result in uneven cleaning that can easily damage the surface of the herbs. Although some mechanized cleaning equipment has been put into use, it generally suffers from problems such as complex structure, incomplete cleaning, serious water waste, and easy clogging, making it difficult to meet the requirements of efficient, environmentally friendly, and gentle cleaning.

[0003] Therefore, this invention proposes a pretreatment device for Chinese medicinal materials, aiming to solve the problems of poor cleaning effect, insufficient equipment stability, and limited cleaning function in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pretreatment device for Chinese medicinal materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pretreatment device for Chinese medicinal materials includes a support assembly. The support assembly includes two sets of support wheels, each with a roller at its top and outer groove rings at both ends that contact the support wheels. The rollers are covered by an outer shell assembly and are positioned on top of the support assembly. The outer shell assembly includes positioning wheels, at least two of which contact the two outer groove rings. The outer groove ring itself is a ring with grooves on its outer circumference. By arranging the two sets of support wheels at the bottom of the rollers and close to both ends, and arranging the two positioning wheels at the top of the rollers and close to both ends, with the outer arc positions of the support wheels and positioning wheels located in the grooves on the outer circumference of the outer groove ring, the rollers at the top of the support frame in the support assembly are positioned within the outer shell assembly. A support cylinder A rotates within the outer casing assembly, passing through and positioned at the top of the drum. A water spray hole A is drilled through the support cylinder A. One end of the support cylinder A is sealed, while the other end communicates with the interior and is connected to a water inlet connector. This water inlet connector connects to an external water inlet pipe, allowing water to be flushed into the support cylinder A and then sprayed out through the water spray hole A into the drum. This washes the medicinal herbs tumbling with the drum. A damping mechanism is used to separate the outer wall of the support cylinder A from the inner wall of the drum. The rubber contact and damping rubber joint increase the friction between the support cylinder A and the roller, so that when the support cylinder A rotates, it can better drive the roller to rotate. There is a transmission wheel B near one end of the support cylinder A. The outer shell assembly is equipped with a drive device, which is a servo motor. The servo motor is protected by a motor shell. The output end of the drive device is the transmission wheel A. The transmission wheel B is connected to the transmission wheel A by a transmission belt. It should be noted that the transmission wheel B and the transmission wheel A can also be transmission sprockets, and the transmission belt can also be a transmission chain, as long as it can play a driving and transmission role. The servo motor starts and drives the transmission wheel A to rotate. Transmission wheel A drives the transmission wheel B to rotate via the transmission belt. Transmission wheel B drives the support cylinder A to rotate. The rotation of the support cylinder A drives the drum to rotate through the friction of the damping rubber. The root and rhizome Chinese medicinal materials in the drum tumble as the drum rotates, and the staff works at the same time.

[0006] Preferably, the support assembly includes a support frame with its top tilted (non-horizontal), so that the roller is also tilted when placed on it, facilitating the rotation and tumbling of the medicinal materials from the tilted downward end. The support frame consists of several crossbar assemblies and includes a water hopper and a material hopper. The water hopper is located below the roller and is used to collect and collect wastewater that leaks out after rinsing the medicinal materials. The material hopper is located below the tilted downward end of the roller and is used to collect the cleaned medicinal materials that fall off after being tumbled by the roller.

[0007] Preferably, the outer shell assembly consists of an outer protective shell composed of two side plates and two end plates. The two side plates include side plate A and side plate B, and the two end plates include end plate A and end plate B. When side plates A and B are symmetrically arranged with respect to the rollers and are set on the top of the support frame, end plates A and B are respectively connected to the two ends of side plates A and B and set on the top of the support frame, thus forming an outer protective shell set on the top of the support frame. The outer protective shell has a top plate, which covers and fastens to the top of the outer protective shell. The top plate and the outer protective shell are hinged and locked and positioned by a latch. In addition, the outer shell assembly not only protects the rollers but also prevents water from splashing and spreading during rinsing as the rollers rotate, thus preventing contamination.

[0008] Preferably, the support wheels on the support frame are located near the four corners of the top of the water receiving hopper, and the positioning wheels at the bottom of the top plate are located near the two ends of the top of the roller. After the top plate is placed on top of the outer protective shell and locked, the positioning wheels at the bottom of the top plate can press into the grooves of the outer groove ring to cooperate with the support wheels to position the roller. Specifically, the two support wheels and the positioning wheels form an outer triangular positioning, and the two sets of support wheels and one positioning wheel form two outer triangular positioning. The roller is positioned near the two ends through the two outer triangular positioning, without hindering the rotation of the roller.

[0009] Preferably, two support cylinders B are provided between end plate A and end plate B. The two support cylinders B are arranged side by side and located below support cylinder A. The two support cylinders B are in contact with the inner wall of the roller. One support cylinder A and the two support cylinders B form an inner triangular positioning in the roller, which can not only provide auxiliary support for the roller, but also prevent the roller from shaking or shifting. The two outer triangular positioning formed by the two sets of support wheels and the two positioning wheels, and the inner triangular positioning formed by one support cylinder A and the two support cylinders B in the roller, cooperate with the two outer triangular positioning to provide stable support and positioning for the roller, thereby improving the stability of rotation.

[0010] Preferably, support cylinder A is provided with brush bristles A, and support cylinder B is provided with brush bristles B. When support cylinder A rotates and drives the roller to rotate, the brush bristles A on support cylinder A and the brush bristles B on support cylinder B can be inserted into the gaps on the surface of the roller. There is a certain damping between the positions of the two support cylinders B through end plate A and end plate B. In addition, the surfaces of the two support cylinders B are in contact with the inner wall of the roller, so that the support cylinders B do not completely follow the rotation of the roller. When the roller rotates, brush bristles A and brush bristles B can clean the water leakage gaps on the surface of the roller. At the same time, when support cylinder B is not rotating, the brush bristles B on it can also clean the inner wall of the roller while the roller is rotating.

[0011] Preferably, the water inlet connector rotatably fitted at the end of the support cylinder A is locked onto the end plate B. A communication assembly is provided on the support cylinder A and the support cylinder B. The communication assembly includes three sleeves connected by a communication pipe. The three sleeves are connected through the communication pipe. A communication water hole is opened on the support cylinder A and the support cylinder B. The three sleeves are respectively fitted onto one support cylinder A and two support cylinders B and cover the communication water hole. A spray hole B is opened through the support cylinder B. When water enters the support cylinder A from the water inlet connector, the water not only enters the support cylinder A, but also enters the sleeve on the support cylinder A through the communication water hole, then enters the other two sleeves through the communication pipe, and then enters the support cylinder B through the communication water hole. In this way, the water entering the support cylinder A and the support cylinder B can be sprayed out from the spray hole A and the spray hole B into the drum to rinse the inner wall of the drum and rinse the medicinal materials tumbling in the drum.

[0012] Preferably, a straight cylinder is movably connected between end plate A and end plate B. The straight cylinder is suspended and does not contact the inner wall of the drum. The straight cylinder is provided with water spray holes C and brush bristles C. One end of the straight cylinder passes through end plate B and is connected to an external water supply pipe through a water pipe connector. In this way, after water enters the straight cylinder, it is sprayed out through the water spray holes C to rinse the Chinese medicinal materials at a closer distance. Combined with the soft brush bristles C, the medicinal materials are cleaned and brushed to improve the cleaning effect of the medicinal materials.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Stable structure and smooth operation: The outer triangular positioning is formed by two sets of support wheels and two positioning wheels, and the inner triangular positioning is formed by support cylinder A and two support cylinders B. This achieves multi-point support for the roller, effectively preventing the roller from shaking or shifting during operation and improving the stability of the equipment operation.

[0014] 2. Significantly improved cleaning effect: Both support cylinder A and support cylinder B are equipped with water spray holes and brush bristles, which can spray and brush the medicinal materials at the same time during the rotation of the drum. The surface of the medicinal materials is cleaned from multiple directions when they tumble in the drum, which is especially suitable for root and rhizome medicinal materials with uneven surfaces.

[0015] 3. High water resource utilization rate: The water circuit between support cylinder A and support cylinder B is connected by the connecting component. The water inlet connector only needs to be connected at one place to realize the simultaneous water supply of multiple pipes. The structure is simple, saves water resources, and avoids the problems of complex and easy leakage of traditional multi-pipe layout.

[0016] 4. Strong self-cleaning function: The bristles can insert into the gaps on the surface of the roller during the rotation of the roller, automatically cleaning the drainage holes that may be blocked, avoiding poor drainage due to the accumulation of mud and sand, and reducing the frequency of equipment maintenance.

[0017] 5. High applicability and convenient operation: The inclined roller setting allows the medicinal materials to automatically move towards the discharge end during the washing process. Combined with the design of the water receiving hopper and the material receiving hopper, continuous operation can be achieved, making it suitable for large-scale production.

There are at least two positioning wheels 151 that contact the two outer groove rings 31. The outer groove ring 31 itself is a ring body with a groove on the outer ring. By arranging the two sets of support wheels 24 at the bottom of the roller 3 and close to both ends, and arranging the two positioning wheels 151 at the top of the roller 3 and close to both ends, and with the outer arc positions of the support wheels 24 and positioning wheels 151 located in the groove on the outer ring of the outer groove ring 31, the roller 3 on the top of the support frame 21 in the support assembly 2 is positioned in the shell assembly 1. A support cylinder A5 rotates within the outer casing assembly 1, passing through and positioned at the top of the drum 3. A water spray hole A54 is drilled through the support cylinder A5. One end of the support cylinder A5 is sealed, while the other end communicates with the interior and is connected to a water inlet connector 52. The water inlet connector 52 connects to an external water inlet pipe, allowing water to be pumped into the support cylinder A5 and sprayed out through the water spray hole A54 into the drum 3. This washes the medicinal herbs tumbling with the drum 3. A damping mechanism is used to separate the outer wall of the support cylinder A5 from the inner wall of the drum 3. The rubber 53 contact and the damping rubber 53 contact increase the friction between the support cylinder A5 and the roller 3, so that when the support cylinder A5 rotates, it can better drive the roller 3 to rotate. There is a transmission wheel B51 near one end of the support cylinder A5. The outer shell assembly 1 is equipped with a drive device 4, which is a servo motor. The servo motor is protected by a motor protective shell. The output end of the drive device 4 has a transmission wheel A41. The transmission wheel B51 and the transmission wheel A41 are connected by a transmission belt. It should be noted that the transmission wheel B51 and the transmission wheel A41 can also be transmission sprockets, and the transmission belt can also be a transmission chain, as long as it can play a driving and transmission role. The servo motor starts and drives the transmission wheel A41 to rotate. The transmission wheel A41 drives the transmission wheel B51 to rotate through the transmission belt. The transmission wheel B51 drives the support cylinder A5 to rotate. The rotation of the support cylinder A5 drives the roller 3 to rotate through the friction of the damping rubber 53. The root and rhizome Chinese medicinal materials in the roller 3 tumble as the roller 3 rotates, and the staff works at the same time.

[0025] Reference Figure 1-9 A pretreatment device for Chinese medicinal materials, more specifically in this invention, includes a support component 2 comprising a support frame 21.

The support frame 21 consists of several crossbar components, and the support frame 21 is provided with a water receiving hopper 22 and a material receiving hopper 23. The water receiving hopper 22 is located below the roller 3 and is used to collect and collect the wastewater that leaks out after rinsing the medicinal materials. The material receiving hopper 23 is located below the inclined downward end of the roller 3 and is used to collect the cleaned medicinal materials that are tumbled and discharged by the roller 3.

[0026] Reference Figure 1-9A pretreatment device for traditional Chinese medicine materials, more specifically in this invention, comprises an outer protective shell consisting of two side plates and two end plates, wherein the two side plates include side plate A11 and side plate B12, and the two end plates include end plate A13 and end plate B14.

When side plates A11 and B12 are symmetrically arranged around the roller 3 and mounted on the top of the support frame 21... The end plate A13 and end plate B14 are respectively connected to the two ends of the side plate A11 and side plate B12 and are set on the top of the support frame 21, thus forming an outer protective shell set on the top of the support frame 21. The outer protective shell has a top plate 15, which covers and fastens to the top of the outer protective shell. The top plate 15 and the outer protective shell are hinged and locked and positioned by a lock. In addition, the outer shell assembly 1 can not only protect the roller 3, but also prevent water from splashing and spreading during rinsing as the roller 3 rotates, thus preventing pollution.

[0029] Reference Figure 1-9A pretreatment device for traditional Chinese medicine materials, more specifically in this invention, includes a support cylinder A5 with brush bristles A55 and a support B6 with brush bristles B62. When the support cylinder A5 rotates and drives the roller 3 to rotate, the brush bristles A55 on the support cylinder A5 and the brush bristles B62 on the support B6 can be inserted into the gaps on the surface of the roller 3. There is a certain damping between the positions of the two support cylinders B6 penetrating the end plate A13 and the end plate B14. In addition, the surfaces of the two support cylinders B6 are in contact with the inner wall of the roller 3, so that the support cylinders B6 do not completely follow the rotation of the roller 3.
