[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

The feeding structure is used to avoid splashing of the medicinal materials during the powdering process, thereby avoiding waste; further, the crushing and filtering structure is used to perform detailed crushing, powdering and screening, and the powder of a predetermined particle size is sent into the powder box, which is convenient for subsequent use, improves production efficiency and reduces rework.

[0019] 2. The present invention screens and separates impurities such as sand, gravel, and soil in medicinal materials through a screening structure arranged at the upper end of the machine platform. The motor drives the gear to rotate, and the cooperation between the gear and the gear ring drives the screening drum to rotate at a constant speed. The centrifugal effect is used to screen out the sand, gravel, and soil impurities in the medicinal materials from the mesh holes of the screening drum, and they are stored in the dust collecting barrel for processing.

[0020] 3. The present invention takes into account the particularity of medicinal materials. There may be sand and gravel inside the rhizomes and leaves. Conventional screening cannot process these sand and gravel. The spiral turning plate and the shifting plate arranged on the inner side of the screening cylinder are used to turn and disperse the medicinal materials, thereby separating the sand and gravel wrapped in the rhizomes and leaves, further avoiding the impact of sand and gravel and soil on cost and quality.

[0021] 4. The present invention drives the crushing knife group to rotate at a high speed in the isolation plate through the action of the motor three and the driving shaft one, and the medicinal materials are crushed into medicinal residues by the impact and shearing of the crushing knife group on the isolation plate. The medicinal residues are blocked in the isolation plate by the action of the screen one and continue to be crushed by the crushing knife group, and are crushed into fine powder sufficient to pass through the screen one, thereby ensuring the uniformity of crushing.

[0022] 5. The present invention utilizes the action of drive shaft 2 and the lever to drive the swing arm to swing left and right in the installation slot, and then drives the arc brush plate to continuously brush the outer surface of screen 1 through the action of the installation slot on the arc brush plate, and utilizes the cleaning action of the brush on the pores of screen 1 to send large particles of medicinal material debris blocked in the pores of screen 1 back to the interior of the isolation plate, thereby preventing screen 1 from being blocked by these large particles that cannot pass through. Simultaneously, the surface of the isolation plate is continuously knocked through the knocking action of the shock component, so that the powder attached to the inside of the isolation plate falls off and falls through screen 1 to the screening component below, thereby ensuring the passing efficiency of the powder through screen 1.

[0023] 6. The present invention utilizes the action of motor 2 on the cable to drive the screening auxiliary component to slide left and right in a circular motion in the straight slide groove, and utilizes the protrusion installed on the auxiliary shaft to move screen 2 to cause the pores of screen 2 to deform and open, thereby promoting the drug powder on the upper layer of screen 2 to pass through screen 2 and fall into the powder box below, while the drug debris that cannot pass through will move to both sides under the continuous rolling of the auxiliary shaft, avoiding affecting the subsequent powder passing efficiency on screen 2, thereby realizing further screening of the drug powder.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1, as Figure 1 and Figure 3As shown, a crushing, screening and filtering device for processing traditional Chinese medicine includes a machine table 1, a screening structure 2 is arranged at the rear part of the upper end of the machine table 1, a feeding structure 3 is fixedly connected to the front end of the screening structure 2 and the upper end of the machine table 1, a crushing and filtering structure 5 connected to the inner cavity of the feeding structure 3 is arranged at the front part of the upper end of the machine table 1, a powder box 4 is slidably connected to the inner cavity of the machine table 1 at the front end, and the upper end of the powder box 4 is connected to the lower end of the crushing and filtering structure 5.

[0037] During the operation of this embodiment, the sand and soil components in the traditional Chinese medicine are first screened out through the action of the screening structure 2, so as to avoid these costs being mixed into the traditional Chinese medicine powder during the subsequent crushing and powdering process, affecting the quality of subsequent boiling and pill making; the medicine is simultaneously crushed and powdered through the cooperation of the feeding structure 3 and the crushing and filtering structure 5, and the medicinal materials are processed into fine powder. The feeding structure 3 is used to prevent the medicinal materials from splashing during the powdering process to avoid waste; further, the crushing and filtering structure 5 is used to perform detailed crushing, powdering and screening, and the powder of a predetermined particle size is sent to the powder box 4, which is convenient for subsequent use, improves production efficiency and reduces rework.

[0038] Embodiment 2: Based on the embodiment 1, this embodiment uses a screening structure 2 disposed on the upper end of the machine 1 to screen and separate the impurities such as sand and soil in the medicinal materials. The motor 24 drives the gear 27 to rotate, and the gear 27 and the gear ring 26 cooperate to drive the screening drum 25 to rotate at a constant speed. The sand and soil impurities in the medicinal materials are screened out from the mesh of the screening drum 25 by centrifugal action, and are stored in the dust collecting drum 28 for processing;

[0039] Furthermore, due to the particularity of the medicinal materials, there will be sand and gravel inside their rhizomes and leaves, which cannot be processed by conventional screening. The spiral turning plate 23 and the material shifting plate 29 arranged on the inner side of the screening cylinder 25 are used to turn and disperse the medicinal materials, thereby separating the sand and gravel wrapped in the rhizomes and leaves, further avoiding the impact of sand and gravel and soil on cost and quality.

[0040] Specifically, in order to achieve the screening of sand and soil components in traditional Chinese medicine, refer to Figure 2 and Figure 3 The screening structure 2 includes a shielding box 21 fixedly connected to the rear of the upper end of the machine 1, a screening drum 25 is rotatably connected to the inner surface of the shielding box 21, a gear ring 26 is symmetrically fixedly connected to the outer surface of the screening drum 25, and a gear 27 meshing with the adjacent gear ring 26 is symmetrically rotatably connected to the front and rear of the inner surface of the shielding box 21, and a motor 24 connected to the two gears 27 through a transmission shaft is fixedly installed at the rear end of the shielding box 21.

[0041] The rotation of motor 24 can drive gear 27 to rotate, and gear 27 meshes with gear ring 26, thereby driving the screening drum 25 to rotate, and the medicinal materials are sent into the screening drum 25 through the relay plate 22 at the rear. Due to the continuous rotation of the screening drum 25, the medicinal materials therein will shake, thereby causing the sand and soil therein to be separated from the medicinal materials, and then fall downward through the mesh holes opened on the screening drum 25, and finally fall into the dust collecting drum 28.

[0042] Furthermore, in order to realize turning over the medicinal materials during the screening process and expose the impurities wrapped inside the medicinal materials, refer to Figure 2 A plurality of material shifting plates 29 are fixedly connected to the inner surface of the screening cylinder 25 in an annular distribution, a spiral material turning plate 23 is fixedly connected to the inner surface of the screening cylinder 25, a dust collecting cylinder 28 is provided on the portion of the inner surface of the shielding box 21 at the upper end of the machine 1, and relay plates 22 are symmetrically fixedly connected to the front and rear ends of the screening cylinder 25, and the relay plate 22 located at the front is connected to the feeding structure 3.

[0043] The spiral turning plate 23 on the inner side of the screening cylinder 25 can cause the medicinal materials to move forward gradually and separate the sand and gravel contained in the medicinal materials during the gradual forward movement. However, the inside of the medicinal materials, that is, the rhizomes and leaves, may also be mixed with some sand and gravel or soil due to contamination during the planting and harvesting processes. These soils cannot be separated by conventional screening alone. Therefore, a turning plate 29 is also installed on the inner side of the screening cylinder 25. The turning plate 29 continuously turns the medicinal materials in the screening cylinder 25, thereby causing the soil in the rhizomes and leaves to be separated from the medicinal materials, thereby further improving the purity of the medicinal materials.

[0044] Furthermore, in order to guide the medicinal materials fed by the screening structure 2 into the crushing and filtering structure 5 and prevent the medicinal materials from flying out of the crushing and filtering structure 5 during the crushing process, thereby reducing the waste of medicinal materials and unnecessary safety hazards, refer to Figure 3 and Figure 4 The feeding structure 3 includes a splash-proof box 31 fixedly connected to the upper end of the machine table 1, the relay plate 22 located at the front is connected to the inner cavity of the splash-proof box 31, the lower part of the inner surface of the splash-proof box 31 is symmetrically connected to a one-way flap 32 for rotation front and back, the inner surface of the one-way flap 32 is fixedly connected to a central axis 34 rotatably connected to the inner surface of the splash-proof box 31, the outer surface of the central axis 34 is symmetrically fixedly connected to a clockwork spring 33 fixedly connected to the inner surface of the splash-proof box 31, the splash-proof box 31 can only rotate downward in one direction, and the lower part of the inner surface of the splash-proof box 31 is connected to the crushing and filtering structure 5.

[0045] The splash box 31 is used to prevent the splash of medicine, and at the same time, it can also guide the medicine provided by the relay plate 22 to move to the crushing and filtering structure 5. The one-way flap 32 arranged at the lower side of the splash box 31 can be flipped in one direction, and the medicine can move from the splash box 31 to the crushing and filtering structure 5. However, it is well known that the medicine will inevitably splash when it is crushed. In this process, if the medicine flies out, it will cause a certain degree of waste. At the same time, there are also some safety hazards, which affect production safety.

[0046] Therefore, the one-way flap 32 can only flip in one direction. When the medicinal materials move from top to bottom, they can force the one-way flap 32 to flip downward and thus enter the crushing and filtering structure 5. After the medicinal materials enter, the central axis 34 will drive the one-way flap 32 to reset under the action of the clockwork spring 33, but the medicinal materials splashing up from the bottom cannot break through the blockade of the one-way flap 32, thereby ensuring production safety.

[0047] Embodiment 3: Based on Embodiment 2, this embodiment further drives the crushing knife group 52 to rotate at high speed in the isolation plate 53 through the action of the motor 3 58 and the drive shaft 1 521, and the crushing knife group 52 impacts and shears the medicinal materials in the isolation plate 53 to crush the medicinal materials into medicinal residues, and the medicinal residues are blocked in the isolation plate 53 by the action of the screen 1 54 and continue to be crushed by the crushing knife group 52, and are crushed into fine powders sufficient to pass through the screen 1 54, thereby ensuring the crushing uniformity;

[0048] Furthermore, the driving shaft 555 and the lever 554 are utilized to drive the swing rod 552 to swing left and right in the mounting groove 557, and then the mounting groove 557 drives the arc brush plate 551 to continuously brush the outer surface of the screen 54, and utilizes the cleaning effect of the brush on the pores of the screen 54 to send the large particles of medicinal material debris blocked in the pores of the screen 54 back to the interior of the isolation plate 53, so as to prevent the screen 54 from being blocked by these large particles that cannot pass through. Simultaneously, the surface of the isolation plate 53 is continuously knocked by the knocking effect of the shock component 56, so that the powder attached to the inside of the isolation plate 53 falls off and passes through the screen 54 to the screening component 57 below, so as to ensure the passing efficiency of the powder through the screen 54.

[0049] Specifically, to achieve drug fragmentation, refer to Figure 5The crushing and filtering structure 5 includes a crushing bin 51 opened at the upper end of the machine 1 and connected to the inner cavity of the splash-proof box 31, an isolation plate 53 is fixedly connected to the inner surface of the crushing bin 51, a crushing knife group 52 that is rotatably connected to the inner surface of the isolation plate 53 is rotatably connected to the inner surface of the crushing bin 51, and the left and right ends of the crushing knife group 52 are fixedly connected to a driving shaft 521 that penetrates the inner cavity of the crushing bin 51 and extends to the left and right ends of the machine 1, and the lower part of the inner surface of the isolation plate 53 is fixedly connected to the isolation plate 53 that is connected to its outer surface, one side of the machine 1 is fixedly connected to a motor 3 58 that is connected to one of the driving shafts 521 through a coupling through a bracket, and anti-blocking components 55 that are rotatably connected to the outer surface of the adjacent driving shaft 521 are symmetrically distributed on the inner surface of the crushing bin 51, and shock components 56 that are symmetrically arranged on the inner surface of the crushing bin 51 and are in contact with the outer surface of the isolation plate 53, and a screening component 57 is arranged at the lower part of the inner surface of the crushing bin 51.

[0050] It should be particularly noted that the above-mentioned crushing knife group 52 is a conventional crushing tool, which crushes the Chinese medicine into fragments by high-speed rotation and friction with the inner wall of the isolation plate 53, and forms powder sufficient to pass through the screen 54 during the continuous crushing process, thereby achieving a crushing effect. The crushing tool is a mature technical means in the prior art and has been widely used in the prior art. In the present invention, it is only used to achieve the function of crushing medicinal materials, and its internal structure or operating principle will not be described in detail.

[0051] The isolation plate 53 installed in the crushing bin 51 is used to provide an environment for the crushing knife group 52 to crush medicinal materials. The screen 54 installed on its inner surface is used to screen the medicinal materials. The medicinal materials that do not meet the specified size are intercepted inside the isolation plate 53 and continue to be crushed by the crushing knife group 52. The crushing knife group 52 simultaneously drives the anti-blocking component 55 to operate, thereby reciprocatingly brushing the outer surface of the screen 54, thereby promoting the powder in the screen 54 to move downward and avoid clogging of the screen 54. At the same time, it will drive the shock component 56 to continuously knock on the surface of the isolation plate 53, further promoting the drug powder in the isolation plate 53 to fall through the screen 54 into the screening component 57 below, and further screened by the screening component 57 to ensure the fineness of the medicine.

[0052] Further, to avoid clogging of the screen 54, refer to Figure 6 and Figure 7The anti-blocking component 55 includes an arc-shaped slide groove 556 opened on the side of the inner surface of the crushing chamber 51 close to the driving shaft 521, and the two arc-shaped slide grooves 556 are opened on the sides away from each other. The inner surfaces of the two mounting grooves 557 are rotatably connected with a lever 554, and the inner surface of the mounting groove 557 is slidably connected with a notch 553 rotatably connected to the outer surface of the adjacent driving shaft 521. The left end of the notch 553 is opened with a notch 553 connected to the right end, and the lever 554 is connected to the swing rod 5 The joint of 52 is slidably connected to the inner surface of the groove 553 through a limiting column, and the side of the lever 554 away from the isolation plate 53 is fixedly connected to the anti-blocking component 55 which is connected to the adjacent driving shaft 521 through a gear set transmission; the swing rods 552 on both sides are rotatably connected to the side of the same side driving shaft 521 with an arc brush plate 551 which is slidably connected to the inner surface of the adjacent arc slot 556 through a pulley, and the inner arc surface of the arc brush plate 551 is provided with a plurality of bristles and is in close contact with the outer surface of the screen 54.

[0053] The driving shaft 2 555 is transmitted through the gear set and the driving shaft 1 521, and will continuously drive the lever 554 to rotate. During this process, the lever 554 will continuously drive the swing rod 552 to swing back and forth along the axis of the driving shaft 1 521 through the action of the slot 553, and the running radius is the same as the radius of the arc chute 556. The arc chute 556 is concentric with the screen 1 54, and the center of the circle is located on the central axis of the driving shaft 1 521, thereby driving the arc brush plate 551 to move back and forth along the restricted trajectory of the arc chute 556, continuously brushing the outer surface of the screen 1 54, pushing the drug powder or debris blocked in the pores of the screen 1 54 back to the inside of the isolation plate 53, and passing through the screen 1 54 or continuing to be crushed under the continuous impact of the crushing knife group 52.

[0054] Further, in order to cooperate with the anti-blocking component 55 to prevent the screen 54 from being blocked during the crushing and powdering process, refer to Figure 8 The shock assembly 56 includes a rotating shaft 561 rotatably connected to the inner surface of the crushing chamber 51, and the outer surface of the rotating shaft 561 is connected to the outer surface of the driving shaft 521 through a transmission belt. The outer surface of the rotating shaft 561 located in the inner cavity of the crushing chamber 51 is linearly distributed and fixedly connected with a plurality of mounting rings 562, and the inner surfaces of the plurality of mounting rings 562 are circularly distributed and rotatably connected with three connecting rods 563, and a rubber ball 564 is fixedly connected to the side of the plurality of connecting rods 563 away from the adjacent mounting ring 562, and the distance between the mounting ring 562 and the isolation plate 53 is less than the length of the connecting rod 563.

[0055] The rotation of the driving shaft 521 will drive the rotating shaft 561 to rotate through the transmission action of the belt, thereby driving the mounting ring 562 to rotate. During the rotation of the mounting ring 562, the connecting rod 563 and the rubber ball 564 will be in a state perpendicular to the central axis of the rotating shaft 561 under the action of centrifugation. However, since the distance between the mounting ring 562 and the isolation plate 53 is smaller than the length of the connecting rod 563, it will hit the outer surface of the isolation plate 53 when passing through the isolation plate 53, causing vibration to the isolation plate 53 and its contents, and promoting the drug powder on the inner surface of the isolation plate 53 to fall downward. However, since the connecting rod 563 is rotating, the connecting rod 563 will fold upward after the collision until the rubber ball 564 completely passes through the isolation plate 53, thereby cyclically colliding with the isolation plate 53.

[0056] Embodiment 4. Based on embodiment 3, this embodiment utilizes the action of motor 2 573 on cable 575 to drive the screening auxiliary component 574 to slide left and right in the straight slide groove 576 in a circular manner, and utilizes the protrusion 5743 installed on the auxiliary shaft 5742 to move the screen 2 572 to cause the pores of the screen 2 572 to deform and open, thereby promoting the drug powder on the upper layer of the screen 2 572 to pass through the screen 2 572 and fall into the powder box 4 below, while the drug debris that cannot pass through will move to both sides under the continuous rolling of the auxiliary shaft 5742, so as to avoid affecting the passing efficiency of subsequent powder particles on the screen 2 572, thereby realizing further screening of the drug powder.

[0057] Specifically, in order to further screen the drug powder and reduce the generation of agglomerates, refer to Fig. 9 The screening component 57 includes a mounting frame 571 fixedly connected to the lower portion of the inner surface of the crushing bin 51, a screen 572 is fixedly connected to the inner surface of the mounting frame 571, a straight slide groove 576 communicating with the rear end is provided at the lower portion of the front end of the mounting frame 571, a screening auxiliary component 574 is commonly provided on the inner surfaces of the two straight slide grooves 576, cables 575 connected to the screening auxiliary component 574 through connecting rings are slidably connected to the inner surfaces of the two straight slide grooves 576, a motor 573 is fixedly connected to the right side of the inner cavity of the machine 1, and the output end of the motor 573 is wound and connected with the rope ends on both sides of the cable 575 through a winding shaft, and the lower end of the mounting frame 571 corresponds to the upper end of the powder box 4.

[0058] When the drug powder falls on the screen 572, it will fall into the powder box 4 below through the screen 572, but some drug residues will inevitably pass through the screen 1 54 and fall on the screen 572, thus requiring further screening through the screen 572. However, the screen 572 cannot move, so the screening auxiliary component 574 is driven by the action of the motor 573 and the cable 575 to slide in a circle in the straight slide groove 576, thereby assisting the powder on the upper side of the screen 572 to move into the powder box 4.

[0059] Further, in order to assist the medicine powder on the upper part of the screen 572 to move into the powder box 4, refer to Fig.10 The screening auxiliary component 574 includes an auxiliary shaft 5742 which is slidably connected to the inner surface of the straight slide groove 576, and a plurality of protrusions 5743 are fixedly connected to the outer surface of the auxiliary shaft 5742. The front and rear ends of the auxiliary shaft 5742 are fixedly connected to gear 2 5741, and the upper parts of the outer surfaces of the two gears 5741 are meshed with racks 5744 which are fixedly connected to the adjacent end surfaces of the mounting frame 571, and the outer surface of the auxiliary shaft 5742 is in close contact with the lower end of the screen 2 572.

[0060] During the rotation of motor 2 573, the winding shaft will be driven to rotate. During the forward and reverse rotation of motor 2 573, the auxiliary shaft 5742 will be pulled by cable 575 to slide left and right in the straight slide groove 576. During the sliding process, the auxiliary shaft 5742 is driven to rotate by the cooperation of gear 2 5741 and rack 5744, and the sieve 2 572 is driven to arch up through the protrusion 5743 on the auxiliary shaft 5742, and the pores on the sieve 2 572 are simultaneously driven to open, so that the drug powder therein is separated from the pores and falls into the powder box 4 below. Furthermore, some large particles of drug residues can be moved to the left and right sides through the protrusions on the sieve 2 572, thereby avoiding the accumulation of drugs on the top of the sieve 2 572 and affecting the subsequent powder separation and filtration efficiency.
