Description

Technical Field

[0001] This utility model applies to the field of traditional Chinese medicine sieving technology, and in particular relates to a gravity sieving device for traditional Chinese medicine. Background Technology

[0002] Currently, Chinese medicinal materials refer to medicinal materials produced in a specific region with specific natural conditions and ecological environment. During the processing of Chinese medicinal materials, it is necessary to screen the raw materials to separate impurities and raw materials of different diameters for subsequent deep processing.

[0003] However, in current methods of sieving traditional Chinese medicine (TCM), the herbs are placed on screens with varying mesh diameters, allowing the substances to be sieved to fall and separate under their own gravity. During this process, when a large quantity of raw TCM is poured onto the screen surface, the accumulation of material prevents it from passing through the screen quickly, thus affecting sieving efficiency. Therefore, we propose a gravity sieving device for TCM. Utility Model Content

[0004] The main purpose of this invention is to provide a gravity sieving device for traditional Chinese medicine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gravity sieving device for traditional Chinese medicine, wherein hollow rotating rods are rotatably installed on both sides of the inner side of the mounting frame, and a fixed frame is movably and detachably installed between the sides of every two sets of hollow rotating rods, and a sieving screen plate is fixedly embedded in the bottom of the inner side of each fixed frame.

[0007] Both ends of the mounting frame are fixedly mounted with transmission frames. Each transmission frame is equipped with a drive mechanism, which is connected to the hollow rotating rod. The mounting frame is equipped with a reciprocating movement mechanism, which is connected to the drive mechanism.

[0008] As an optional solution to the technical solution of this application, the driving mechanism includes a follower gear and a transmission gear block. Each hollow rotating rod is rotatably mounted inside the transmission frame via a bearing. A follower gear is fixedly sleeved on the outer side of each hollow rotating rod. A movable frame is slidably mounted inside each transmission frame. Transmission gear blocks are fixedly mounted at both ends of the inner sidewall of each transmission frame. Movable slots are opened inside both ends of the sidewall of each transmission frame, and the movable frames are slidably mounted inside the movable slots.

[0009] By adopting the above technical solution, the meshing transmission action of the transmission gear and the follower gear can cause the follower gear to reciprocate clockwise and counterclockwise, driving the fixed frame and the screening screen plate to tilt synchronously inside the installation frame. This allows the Chinese herbal raw materials piled inside the fixed frame to tilt and reciprocate on the surface of the screening screen plate as the fixed frame rotates, thus dispersing the Chinese herbal materials and improving the screening efficiency of the Chinese herbal raw materials.

[0010] As an optional solution to the technical solution of this application, the reciprocating moving mechanism includes a connecting plate and a rotating plate. Guide tubes are fixedly installed at both ends of the side of the mounting frame. A guide groove is opened inside the guide tube, and a fixed rod is slidably inserted into the guide groove. A connecting block is fixedly installed at the top of the side of each fixed rod. An mounting rod is fixedly installed on the outside of each connecting block. A rotating sleeve is rotatably sleeved on the outside of each mounting rod through a bearing. A connecting plate is fixedly installed on the outside of each rotating sleeve. A support rod is rotatably inserted into the end of each connecting plate away from the connecting block through a bearing. A rotating plate is rotatably installed at both ends of the outside of the mounting frame, and the side of the support rod is rotatably inserted into the side of the rotating plate through a bearing. A rotating motor is fixedly installed at both ends of the inner side of the mounting frame, and the side of the rotating motor drive shaft is fixedly connected to the outside of the rotating plate through a coupling. A connecting rod is fixedly installed at both ends of the outside of each movable frame. A transmission plate is fixedly installed between the sides of every two sets of connecting rods, and the side of the transmission plate is fixedly connected to the top of the outside of the fixed rod.

[0011] By adopting the above technical solution, the two ends of the connecting plate are respectively connected to the fixed block and the outer side of the rotating plate by combining the rotating sleeve and the support rod. Then, when the rotating motor runs and drives the rotating plate to rotate synchronously on the outer wall of the mounting frame, the circumferential rotation of the rotating plate can be converted into a horizontal reciprocating force on the connecting block and the fixed rod under the connecting transmission action of the connecting plate. This allows the fixed rod to drive the movable frame to move horizontally back and forth synchronously inside the transmission frame.

[0012] As an optional solution to the technical solution of this application, each of the fixed frames has a connecting bolt threaded through both ends on its side, and the top of the connecting bolt is threaded into the hollow rotating rod.

[0013] By adopting the above technical solution, the connecting bolts can be screwed on to disassemble the fixed frame and the hollow rotating rod, thereby allowing the screened Chinese herbal raw materials inside the fixed frame to be removed, facilitating the dumping and transfer of the Chinese herbal raw materials.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A gravity sieving device for traditional Chinese medicine, as described in this application, comprises a fixed frame and a sieving screen plate rotatably mounted on both sides inside the mounting frame, and a follower gear connecting the fixed frame and the movable frame. A rotating sleeve and a support rod connect the two ends of a connecting plate to the fixed block and the outer side of the rotating plate, respectively. When the rotating motor rotates, causing the rotating plate to rotate synchronously on the outer wall of the mounting frame, the circumferential rotation of the rotating plate is converted into horizontal reciprocating movement of the connecting block and the fixed rod under the connecting transmission action of the connecting plate. By applying force, the fixed rod can drive the movable frame to move horizontally back and forth inside the transmission frame. Combined with the meshing transmission of the two sets of transmission gears and the follower gear, the follower gear can drive the fixed frame and the screening screen plate to tilt synchronously inside the installation frame by rotating clockwise and counterclockwise. This allows the Chinese herbal raw materials piled inside the fixed frame to tilt and roll back and forth on the surface of the screening screen plate as the fixed frame rotates, thus dispersing the Chinese herbal materials and improving the screening efficiency of the Chinese herbal raw materials.

[0016] 2. The traditional Chinese medicine gravity screening device of this application is connected to the side of the hollow rotating rod by connecting bolts through the fixed frame. When the hollow rotating rod rotates, it can drive the fixed frame to rotate synchronously. This rolling motion of the traditional Chinese medicine raw materials accumulated on the surface improves screening efficiency. At the same time, the connecting bolts can be loosened to separate the fixed frame and the hollow rotating rod, thereby removing the screened traditional Chinese medicine raw materials from the fixed frame and facilitating the dumping and transfer of the traditional Chinese medicine raw materials.

Hollow rotating rods 11 are rotatably installed on both sides of the inner side of the mounting frame 1, and there are four sets of hollow rotating rods 11. A fixed frame 12 is movably and detachably installed between the sides of every two sets of hollow rotating rods 11. A sieving screen plate 13 is fixedly embedded in the bottom of the inner side of each fixed frame 12. A connecting bolt 14 is threaded through and screwed to both ends of the side of each fixed frame 12. The top of the side of the connecting bolt 14 is threaded into the inner side of the hollow rotating rod 11. The inner side of the hollow rotating rod 11 near the fixed frame 12 has a thread that matches the outer wall of the connecting bolt 14.

[0022] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, guide tubes 3 are fixedly installed at both ends of the side of the mounting frame 1. A guide groove 31 is opened inside the guide tube 3, and the fixing rod 26 is slidably inserted into the guide groove 31. A connecting block 32 is fixedly installed at the top of the side of each fixing rod 26. An mounting rod 33 is fixedly installed on the outside of each connecting block 32. A rotating sleeve 34 is rotatably sleeved on the outside of each mounting rod 33 through a bearing. A connecting plate 35 is fixedly installed on the outside of each rotating sleeve 34. A support rod 37 is rotatably inserted into the end of each connecting plate 35 away from the connecting block 32 through a bearing. A rotating plate 36 is rotatably installed at both ends of the outside of the mounting frame 1, and the side of the support rod 37 is rotatably inserted into the inside of the side of the rotating plate 36 through a bearing. A rotating motor 4 is fixedly installed at both ends of the inner side of the mounting frame 1, and the side of the drive shaft of the rotating motor 4 is fixedly connected to the outside of the rotating plate 36 through a coupling.

[0023] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, each of the movable frames 22 has a connecting rod 24 fixedly installed at both ends of its outer side, and a transmission plate 25 is fixedly installed between the sides of every two sets of connecting rods 24, and the side of the transmission plate 25 is fixedly connected to the top of the outer side of the fixed rod 26.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown, each hollow rotating rod 11 is rotatably mounted inside the transmission frame 2 via a bearing on its side. A follower gear 21 is fixedly sleeved on the outside of each hollow rotating rod 11. A movable frame 22 is slidably mounted inside each transmission frame 2, and the follower gear 21 is located inside the movable frame 22. Transmission gear blocks 23 are fixedly mounted at both ends of the inner sidewall of each transmission frame 2, and two sets of transmission gear blocks 23 are diagonally arranged inside the movable frame 22. Movable grooves 27 are opened inside both ends of the side of each transmission frame 2, and the movable frame 22 is slidably mounted inside the movable grooves 27.

[0025] During operation, the raw materials of traditional Chinese medicine to be screened and processed are poured into the fixed frame 12. Then, the rotating motor 4 is turned on by the external control switch, causing it to rotate and drive the rotating plate 36 to rotate synchronously on the outer wall of the mounting frame 1. Then, by combining the rotating sleeve 34 and the support rod 37, the two ends of the connecting plate 35 are respectively connected to the fixed block and the outer side of the rotating plate 36. Under the connecting transmission action of the connecting plate 35, the circumferential rotation of the rotating plate 36 can be converted into a horizontal reciprocating force on the connecting block 32 and the fixed rod 26. This allows the fixed rod 26 to drive the movable frame 22 to move horizontally back and forth synchronously inside the transmission frame 2. At the same time, the transmission gear blocks 23 on both sides inside the movable frame 22 can move horizontally back and forth synchronously, while the transmission gear blocks 23 on the upper and lower sides move horizontally back and forth. 3. During the movement, after meshing with the follower gear 21 for transmission, the follower gear 21 can drive the fixed frame 12 and the screening screen plate 13 to tilt synchronously inside the mounting frame 1 in clockwise and counterclockwise directions. This allows the Chinese herbal raw materials piled inside the fixed frame 12 to tilt and roll back and forth on the surface of the screening screen plate 13 as the fixed frame 12 rotates, thus dispersing the Chinese herbal materials. Under the screening action of the two sets of screening screen plates 13, Chinese herbal raw materials of different diameters can be screened and separated. Then, the connecting bolt 14 is tightened to remove it from the fixed frame 12 and the hollow rotating rod 11. Finally, the two sets of fixed frames 12 are lifted to remove them from the mounting frame 1, and the Chinese herbal raw materials piled on their surface are transferred.
