[0023] like Figures 1 to 12 As shown, an embodiment of the present invention provides a Chinese medicinal material cleaning and drying device, including a cylinder 100, a cleaning cylinder and a conversion mechanism. The cylinder 100 is vertically arranged, and a volumetric cavity with a variable volume is provided in the cleaning cylinder. The cleaning cylinder includes a top plate 101, a filter plate 102, a connecting plate 103 and a bottom seal 104. The top plate 101 is rotatably arranged in the cylinder 100 axis. There is a spacing between the axis of the top plate 101 and the axis of the cylinder 100 and the extension direction is consistent. There are multiple filter plates 102 and multiple connecting plates 103. The multiple filter plates 102 and the multiple connecting plates 103 are alternately distributed around the axis of the top plate 101, and the space between adjacent filter plates 102 and connecting plates 103 is consistent. The top plate 101 and the connecting plate 103 are hinged together by a hinge shaft 105, which extends in the vertical direction, and each hinge shaft 105 is slidably arranged on the top plate 101 along the radial direction of the top plate 101, and multiple filter plates 102 and multiple connecting plates 103 are respectively slidably connected to the bottom surface of the top plate 101, and the bottom cover 104 is arranged below the filter plate 102 and the connecting plate 103, and the bottom cover 104 is respectively connected to the filter plate 102 and the connecting plate 103; the cavity is surrounded by the top plate 101, the bottom cover 104, the multiple filter plates 102 and the multiple connecting plates 103; each filter plate 102 is provided with a plurality of filter holes 106, and the liquid in the cylinder 100 can enter and exit the cavity through the filter holes 106.

[0024] Assuming that the direction in which the filter plate 102 moves away from the axis of the top plate 101 is the forward direction, in the forward direction of the filter plate 102, the filter plate 102 has a first state and a second state; in the first state, one of the hinge shafts 105 on each filter plate 102 is located in front of the other hinge shaft 105; in the second state, the two hinge shafts 105 on each filter plate 102 are at the same distance from the axis of the top plate 101.

[0025] The conversion mechanism is used to control the volume change of the cavity and to change the front-to-back sequence of the two hinge shafts 105 on the filter plate 102 when the filter plate 102 switches between the first state and the second state.

[0026] A volume-variable cavity is provided, and the liquid in the cleaning cylinder and the liquid in the cylinder body 100 can be quickly exchanged; through the coordinated arrangement of the filter plate 102 and the connecting plate 103, when the filter plate 102 is in the first state, the liquid in the cylinder body 100 moves in the same direction after entering the cavity, and the liquid in the cavity can generate a vortex. When the filter plate 102 is in the second state, the flow direction of the liquid in the cavity is no longer in the same direction, and the relative speed between the liquid entering the cavity and the Chinese medicinal materials in the cavity is large, so that the Chinese medicinal materials can be better cleaned; a conversion mechanism is provided, and after the filter plate 102 enters the second state from the first state and then enters the first state, the hinge shaft 105 on the front side of the same filter plate 102 is not the same, and the direction of the filter plate 102 is opposite, and the rotation direction of the vortex generated by the liquid entering the cavity is opposite, which can also perform impact cleaning on the Chinese medicinal materials in the cavity.

[0027] In this embodiment, the conversion mechanism includes a connecting rod 107 and a guide assembly. The connecting rod 107 is provided with a plurality of connecting rods 107, and the plurality of connecting rods 107 are evenly divided into two groups. The two groups of connecting rods 107 extend along the axial direction of the top plate 101, and each group of connecting rods 107 is divided into a plurality of small parts. The plurality of small parts are evenly distributed around the rotation axis of the top plate 101, and each small part includes two connecting rods 107, wherein one end of the two connecting rods 107 in one small part of one group of connecting rods 107 is rotatably connected, and the other ends of the two connecting rods 107 are respectively rotatably connected to one end of a connecting rod 107 in two adjacent small parts; the middle parts of the two connecting rods 107 in a small part of one group of connecting rods 107 are respectively rotatably connected to the middle parts of one of the two adjacent small parts in the other group of connecting rods 107; the rotation axis of each connecting rod 107 extends in the vertical direction; one end of the rotatably connected two connecting rods 107 of a small part of a group of connecting rods 107 close to the filter plate 102 is sleeved on a hinge The two middle parts of the two connecting rods 107 are respectively sleeved on the two hinge shafts 105 adjacent to the hinge shaft 105, and there is only one hinge shaft 105 between the two adjacent small parts in the group that is not connected to the connecting rod 107. When one of the filter plates 102 or the connecting plate 103 is pushed, the filter plate 102 or the connecting plate 103 will drive all the filter plates 102 and the connecting plates 103 to move synchronously through the linkage between the multiple connecting rods 107, and the pushed filter plate 102 or the connecting plate 103 will move far away. When moving away from the axis of the top plate 101, all filter plates 102 or connecting plates 103 simultaneously move away from the axis of the top plate 101, and the multiple filter plates 102 and connecting plates 103 gradually form a nearly circular shape, increasing the volume of the cavity. When the pushed filter plates 102 or connecting plates 103 move toward the axis of the top plate 101, all filter plates 102 or connecting plates 103 simultaneously approach the axis of the top plate 101, and the multiple filter plates 102 and connecting plates 103 gradually move closer to each other and shrink, reducing the volume of the cavity. The guide assembly is used to change the orientation of the filter holes 106 on the filter plates 102 when the volume of the cavity is maximum.

[0028] In this embodiment, a plurality of slide grooves 108 are provided on the top plate 101, and the number of the slide grooves 108 is consistent with the number of the hinge shafts 105. Each slide groove 108 extends along the radial direction of the top plate 101 and penetrates the top plate 101 along the axial direction of the top plate 101. The end of each hinge shaft 105 close to the top plate 101 is slidably set in one of the slide grooves 108. Two sets of connecting rods 107 are located above the top plate 101. The slide grooves 108 can further limit the movement direction of the filter plate 102 and the connecting plate 103, so that the filter plate 102 can be converted between the first state and the second state more accurately.

[0029] In this embodiment, two sets of connecting rods 107 are also provided at the bottom end of the filter plate 102, so that both ends of the filter plate 102 and the connecting plate 103 can be subjected to force at the same time, and the movement of the filter plate 102 and the connecting plate 103 is smoother.

[0030] In this embodiment, the guide assembly includes two arc plates 109, two top blocks 110 and two telescopic rods 111. The two arc plates 109 are fixedly mounted on the bottom of the cylinder 100, and the two arc plates 109 are rotationally symmetrical about the center of the bottom of the cylinder 100. A corresponding arc groove 112 is opened on each arc plate 109, and a pole is provided in the middle of each arc groove 112, and the distance between the pole and the axis of the cylinder 100 is the farthest; the two telescopic rods 111 are both provided on a group of connecting rods 107 away from the filter plate 102 at the bottom end of the filter plate 102, and the two telescopic rods 111 are located on a side of one connecting rod 107 in the group of connecting rods 107 away from the filter plate 102, and the two telescopic rods 111 are respectively connected to the same connecting plate 103 or the filter plate 102. The two hinge shafts 105 are coaxial, and each telescopic rod 111 can slide in a corresponding arc groove 112. The telescopic rod 111 is an electric push rod. When the top plate 101 rotates to a certain position in the cylinder 100, one of the telescopic rods 111 will contact an arc plate 109. At this time, the telescopic rod 111 contracts and the arc plate 109 will not contact the telescopic rod 111, and the rotation of the top plate 101 in the cylinder 100 will not be restricted; the two ends of the two arc grooves 112 have overlapping parts. When one of the telescopic rods 111 moves to its end in the corresponding arc groove 112, the other telescopic rod 111 has already slid into the corresponding arc groove 112, and the movement of the filter plate 102 and the connecting plate 103 is always guided by the arc groove 112.

[0031] Two top blocks 110 are arranged at the bottom of the cylinder 100, and each top block 110 is arranged corresponding to an arc plate 109. The top blocks 110 are made of flexible material. When one of the telescopic rods 111 slides to the extreme point of the corresponding arc groove 112, the other telescopic rod 111 is located on the side of the top block 110 away from the axis of the cylinder 100 and is slidably connected to the top block 110. Under the guidance of the arc groove 112, the telescopic rod 111 in the arc groove 112 drives the corresponding hinge shaft 105 toward the axis of the cylinder 100. Under the cooperation of the other telescopic rod 111 and the top block 110, the hinge shaft 105 adjacent to the hinge shaft 105 also approaches the axis of the cylinder 100, and the direction of the filter hole 106 on the filter plate 102 changes accordingly.

[0032] In this embodiment, in the rotation direction of the cleaning cylinder, a filter screen is provided on the filter plate 102 located in front of the axis of the top plate 101, and the filter screen is located outside the cavity. During the rotation of the cleaning cylinder, the liquid in the cylinder body 100 is more likely to enter the interior of the cylinder body 100 from the filter plate in front of the axis of the top plate 101, and more impurities in the liquid will be intercepted by the filter screen. After the cleaner liquid enters the cylinder body 100 and exchanges with the liquid in the cavity, the liquid with impurities in the cavity is more likely to be discharged from the filter plate 102 on the rear side of the top plate 101 into the cylinder body 100. The volume change of the cavity causes the liquid in the cavity to backflush the filter screen, which has a certain cleaning effect on the filter screen.

[0033] In this embodiment, the thickness of the filter plate 102 is greater than the diameter of the hinge shaft 105, and the thickness direction of the filter plate 102 is perpendicular to the extension direction of the line connecting the two hinge shafts 105 on the filter plate 102. The filter holes 106 on the filter plate 102 penetrate the filter plate 102 along the thickness direction of the filter plate 102. When there is an angle between the extension direction of the filter holes 106 and the radial direction of the top plate 101, the liquid entering the cavity from the filter holes 106 will flow along the extension direction of the filter holes 106, and a vortex will be formed in the cavity, thereby accelerating the movement of the Chinese medicinal materials in the cavity, thereby making the surface of the Chinese medicinal materials rinsed more cleanly.

[0034] In this embodiment, a bracket 113, a rotating plate 114 and a motor 115 are provided on the cylinder 100. The cylinder 100 has no top. The bracket 113 is telescopically arranged on the top of the cylinder 100 in the vertical direction. One end of the rotating plate 114 is rotatably arranged below the bracket 113. The other end of the rotating plate 114 is connected to the top plate 101. The rotation axis of the rotating plate 114 coincides with the axis of the cylinder 100. The motor 115 is fixedly installed on the bracket 113, and the output end of the motor 115 is connected to the end of the rotating plate 114 that rotates on the bracket 113. The motor 115 rotates The top plate 101 rotates within the cylinder 100 via a rotating plate 114. A feed port 118 is located in the middle of the top plate 101. A movable portion 116 is provided on the bottom cover 104. The movable portion 116 and the bottom cover 104 are connected by a zipper. Like the bottom cover 104, the movable portion 116 is made of a flexible material. When the volume of the chamber changes, the multiple filter plates 102 can drive the bottom cover 104 and the movable portion 116 to move. The bottom cover 104 and the movable portion 116 fold to accommodate the change in the chamber volume, preventing the medicinal materials in the chamber from escaping. The bracket 113 is telescopic. After the Chinese medicinal materials are cleaned, the cleaning cylinder can be taken out of the cylinder 100 and removed from the movable portion 116.

[0035] In this embodiment, a drying mechanism is provided on the rotating plate 114 , and the drying mechanism is located above the feed port 118 , and the Chinese medicinal materials in the cleaning cylinder can be dried through the feed port 118 .

[0036] In this embodiment, a drain port 117 is provided on the side of the cylinder 100 .

[0037] The working principle of the Chinese medicinal material cleaning and drying device provided in the above embodiment is as follows: First, add cleaning water into the cylinder 100, then add Chinese medicinal materials into the cleaning cylinder through the feed port 118, and then start the motor 115. The motor 115 drives the rotating plate 114 to rotate. The rotation of the rotating plate 114 drives the top plate 101 to rotate around the axis of the cylinder 100. While the top plate 101 rotates, it drives the telescopic rod 111 to rotate in the corresponding arc groove 112 through the filter plate 102, the connecting plate 103, and the connecting rod 107.

[0038] Assume that the two telescopic rods 111 are respectively the first rod and the second rod. Figure 9As shown, the position of point P is the position of the first rod, and the position of point O is the position of the second rod. When the first rod just slides into the corresponding arc groove 112, the volume of the cavity is the smallest, the angle between the adjacent connecting plates 103 and the filter plates 102 is the smallest, and the filter plates 102 are in the first state. The top plate 101 continues to rotate, and the first rod continues to rotate in the arc groove 112. Under the guidance of the arc groove 112, the first rod gradually moves away from the axis of the top plate 101. The first rod drives multiple hinge shafts 105 to slide in the direction away from the axis of the top plate 101 in the slide groove 108 through the connecting rod 107. The hinge shaft 105 drives the filter plates 102 and the connecting plates 103 to move synchronously. As the hinge shaft 105 slides, the angle between the adjacent filter plates 102 and the connecting plates 103 becomes larger and larger, and the volume of the cavity gradually increases. When the first rod moves to the extreme point of the arc groove 112 (as shown in FIG. Figure 10 As shown in FIG1 , the second rod will pass over the arc plate 109 and contact the corresponding top block 110. The first rod is in front of the second rod. The top plate 101 continues to rotate. The first rod will drive the corresponding hinge shaft 105 to approach the axis of the top plate 101. The second rod will be subjected to a resistance under the action of the top block 110 and will move away from the axis of the top plate 101, forming a Figure 11 , at this time, the first rod is located at the rear side of the second rod; the top plate 101 rotates, and the hinge shaft 105 corresponding to the first rod approaches the axis of the top plate 101 under the guidance of the arc groove 112, and the second rod will also be separated from the corresponding top block 110 and move with the hinge shaft 105 corresponding to the first rod (as shown in FIG. Figure 12 During this process, the positions of the first rod and the second rod relative to the axis of the top plate 101 are exchanged, the orientation of the filter plate 102 is changed, and the flow direction of the water entering the cavity through the filter plate 102 is also changed, so that the Chinese medicinal materials in the cavity can be better cleaned.

[0039] Similarly, when the first rod is about to disengage from the corresponding arc groove 112 , the second rod will slide into the corresponding arc groove 112 , completing the same action, causing the filter plate 102 to change its direction again.

[0040] After the Chinese medicinal materials are cleaned, the water in the cylinder 100 is drained through the drain port 117, and then the drying mechanism is started to dry the Chinese medicinal materials in the cavity. After the Chinese medicinal materials are dried, the bracket 113 is started, and the bracket 113 drives the cleaning cylinder to move upward and out of the cylinder 100, and then the zipper between the movable part 116 and the bottom cover 104 is opened to take out the Chinese medicinal materials.

[0041] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
