[0002] The crushing of raw materials for traditional Chinese medicine processing is an important link in the production process of traditional Chinese medicine. At present, mechanical crushing methods are usually used to crush traditional Chinese medicine, and screening is carried out through a sieve plate. Incompletely crushed traditional Chinese medicine materials (and even some stones, etc.) are likely to cause blockage of the sieve plate. Once blockage occurs, it is difficult to screen the medicinal materials, and it is necessary to stop the machine for blockage removal operations. This not only delays the medicinal material crushing work, increases the work intensity, but also greatly reduces the crushing and processing efficiency of the medicinal materials.

One end of the connecting shaft penetrates through the feeding hopper and is fixedly connected with a driven gear, and the driven gear is externally meshed with a driving gear, and the driving gear is fixed at the end of the screening assembly.

[0008] As a further solution of the present invention, the screening assembly includes a multi-stage sieve cylinder. The two sides of the outer wall of the multi-stage sieve cylinder are respectively connected with two bearing seats. A number of first-stage sieve holes, second-stage sieve holes, third-stage sieve holes and discharge holes are arranged outside the multi-stage sieve cylinder. The side wall of the multi-stage sieve cylinder is designed to be inclined to the left, and the diameter of the inner wall of the multi-stage sieve cylinder increases sequentially from right to left. The drying and cleaning assembly includes a blower, which is fixedly installed on a fixing frame. Two air outlets of the blower are respectively communicated with air guide pipes, and the bottoms of the two air guide pipes are connected to an air box. The air box penetrates and is fixed in the middle of the fixing frame. A number of air outlet holes are arranged at the bottom of the air box, and a cleaning brush is installed below the air box, and the cleaning brush contacts the top of the multi-stage sieve cylinder.

[0009] As a further solution of the present invention, three triangular blocks are respectively arranged on the two sides of the outer wall of the multi-stage sieve cylinder, and the distances between the three triangular blocks on the same side are equal. A support frame is fixedly connected inside the multi-stage sieve cylinder, a fixed shaft is fixed in the middle of the support frame, the fixed shaft is installed at the top end of a support leg through a shaft seat, and a driven wheel is fixedly connected to one end of the fixed shaft. The driven wheel is connected to the end of the crushing assembly through a transmission belt.

[0010] As a further solution of the present invention, the aggregate assembly includes a turnover box, and two bearing seats are respectively installed on both sides of the turnover box. The turnover box is fixed in the support leg. Material dropping hoppers are respectively arranged on both sides of the bottom of the turnover box, and discharge hoppers are respectively arranged on both sides in front of the turnover box.

[0011] As a further solution of the present invention, the knocking assembly includes a knocking block. The bottom of the knocking block is arc-shaped and contacts the outer wall of the multi-stage sieve cylinder. The top of the knocking block penetrates through the fixing frame and is fixedly connected with a top block. Slide rods are respectively fixed on both sides of the bottom of the top block, and the slide rods penetrate and slide in the fixing frame. A spring is sleeved outside the slide rods, and both ends of the spring are fixedly connected with the opposite surfaces of the top block and the fixing frame.

[0012] A method for using a raw material crushing device for traditional Chinese medicine processing, the method comprising the following steps: When crushing traditional Chinese medicine raw materials, add the raw materials into the crushing box to make them contact with the crushing components, control the driving mechanism to work so that the gear set drives the crushing rollers to rotate, and crush the raw materials by extrusion with the crushing rollers, so that the crushed raw materials fall into the blanking box. Because the bottom of the blanking box is inclined, the crushed materials inside the blanking box can slide to the lower discharge port and fall into the guide hopper; During the rotation of the crushing rollers, the driving wheels at the ends can be driven to rotate. The driving wheels drive the driven wheels to rotate through the transmission belt. The driven wheels drive the driving gears to rotate through the fixed shafts. The driving wheels drive the spiral blades to rotate through the driven gears and the connecting shafts. During the rotation of the spiral blades, the crushed materials can be sent from the guide hopper into the multi-stage sieve cylinder. Because the fixed shafts are fixed to the multi-stage sieve cylinder through the support frames, the fixed shafts can drive the multi-stage sieve cylinder to rotate inside the two bearing seats through the support frames during rotation, and the multi-stage sieve cylinder is supported by the bearing seats to improve the stability of the rotation of the multi-stage sieve cylinder; Because the side wall of the multi-stage sieve cylinder is designed to be inclined to the left, and the inner diameter of the inner wall of the multi-stage sieve cylinder increases sequentially from right to left, the multi-stage sieve cylinder can convey the crushed materials to the left during rotation. The crushed materials are first screened through the first-level sieve holes. The small-particle crushed materials can pass through the first-level sieve holes and fall into the turnover box and be discharged from the rightmost discharge hopper. When the crushed materials move to the middle of the multi-stage sieve cylinder, the second-level sieve holes can screen the crushed materials. The medium-particle crushed materials can pass through the second-level sieve holes and fall into the turnover box and be discharged from the right discharge hopper. As the crushed materials continue to move to the left, the third-level sieve holes can screen the crushed materials again. The screened large-particle crushed materials can fall into the turnover box and be discharged from the left discharge hopper. As the multi-stage sieve cylinder drives the crushed materials to continue moving to the left, some of the crushed materials that cannot be screened are discharged through the discharge holes and discharged from the discharge hopper on the left side of the bottom of the turnover box. Therefore, the purpose of multi-stage screening and collection of crushed materials of different specifications can be achieved; During the process of the multi-stage sieve cylinder driving the crushed materials to move, since the multi-stage sieve cylinder is always in a rotating state, when the crushed materials blocked in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes move to the upper part, due to the gravity of the crushed materials themselves, part of the crushed materials can fall into the bottom inside the multi-stage sieve cylinder, thereby preventing the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes from being blocked and affecting the screening effect. When the crushed materials are stuck in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes and are difficult to discharge, the multi-stage sieve cylinder drives a plurality of triangular blocks on both sides to rotate. When the inclined surface of the triangular block moves to the position of the knocking block, because the bottom of the knocking block is designed as an arc, the inclined surface part of the triangular block can squeeze the knocking block, so that the knocking block drives the sliding rod to move upward through the top block, and the top plate stretches the spring. When the triangular block rotates and disengages from the knocking block, the top block is driven to move downward by the pulling force of the spring, so that the top block can drive the knocking block to quickly move downward and knock on the multi-stage sieve cylinder, causing the multi-stage sieve cylinder to vibrate and shake off the crushed materials in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes. As the multi-stage sieve cylinder drives the triangular block to continuously rotate, the knocking block can intermittently knock on the multi-stage sieve cylinder to achieve the purpose of automatically clearing the blockage of the multi-stage sieve cylinder; During the rotation of the multi-stage sieve cylinder, the cleaning brush at the bottom of the air box can contact the top of the multi-stage sieve cylinder. Since the cleaning brush is composed of several filaments and is flexibly designed, the filaments in the cleaning brush can penetrate the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes outside the multi-stage sieve cylinder. When the multi-stage sieve cylinder rotates, the cleaning brush can automatically clean the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes, further improving the blockage clearing effect. At the same time, the blower is started. The blower can introduce the gas into the air box through the air duct. The gas in the air box is blown from a plurality of air outlet holes opened at the bottom to the multi-stage sieve cylinder, cooperating with the cleaning brush to clean the multi-stage sieve cylinder and improving the cleaning effect. Moreover, the hot air can enter the inside of the multi-stage sieve cylinder through the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes, and can dry the crushed materials during the movement process, accelerating the water loss speed of the traditional Chinese medicine crushed materials.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the shredded materials are fed from the material guiding hopper into the multi-stage sieve cylinder through the feeding assembly. During the process of the multi-stage sieve cylinder driving the shredded materials to move, since the multi-stage sieve cylinder is always in a rotating state, when the shredded materials blocked in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes move to the upper part, due to the gravitational force of the shredded materials themselves, part of the shredded materials can fall into the bottom inside the multi-stage sieve cylinder, thereby preventing the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes from being blocked and affecting the screening effect. When the shredded materials are stuck in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes and are difficult to discharge, the multi-stage sieve cylinder drives a plurality of triangular blocks on both sides to rotate. When the inclined surface of the triangular block moves to the position of the knocking block, because the bottom of the knocking block is designed as an arc, the inclined surface part of the triangular block can squeeze the knocking block, so that the knocking block drives the sliding rod to move upward through the top block, and the top plate stretches the spring. When the triangular block rotates and disengages from the knocking block, the spring's pulling force drives the top block to move downward, enabling the top block to drive the knocking block to quickly move downward and knock on the multi-stage sieve cylinder, causing the multi-stage sieve cylinder to vibrate and shake off the shredded materials in the first-stage sieve holes, second-stage sieve holes and third-stage sieve holes. As the multi-stage sieve cylinder drives the triangular block to continuously rotate, the knocking block can intermittently knock on the multi-stage sieve cylinder, achieving the purpose of automatic blockage clearing without affecting the normal operation of the equipment. Cooperating with the drying and cleaning assembly to clean the multi-stage sieve cylinder and dry the Chinese medicine shredded materials inside it is beneficial to improving the processing efficiency of Chinese medicine raw materials; 2. In the present invention, the support frame drives the multi-stage sieve cylinder to rotate inside the two bearing seats. The side wall of the multi-stage sieve cylinder is designed to be inclined to the left, and the inner diameter of the inner wall of the multi-stage sieve cylinder increases sequentially from right to left, enabling the multi-stage sieve cylinder to convey the shredded materials to the left during rotation. The shredded materials are first screened through the first-stage sieve holes. The small-particle shredded materials can pass through the first-stage sieve holes and fall into the turnover box and be discharged from the rightmost discharge hopper. When the shredded materials move to the middle of the multi-stage sieve cylinder, the second-stage sieve holes can screen the shredded materials. The medium-particle shredded materials can pass through the second-stage sieve holes and fall into the turnover box and be discharged from the right discharge hopper. As the shredded materials continue to move to the left, the third-stage sieve holes can screen the shredded materials again. The screened large-particle shredded materials can fall into the turnover box and be discharged from the left discharge hopper. As the multi-stage sieve cylinder drives the shredded materials to continue moving to the left, some shredded materials that cannot be screened are discharged through the discharge holes and are discharged from the discharge hopper on the left side of the bottom of the turnover box. Therefore, the purpose of multi-stage screening of shredded materials of different specifications can be achieved, and the shredded materials of multiple specifications can be discharged from multiple discharge hoppers and discharge ports respectively, facilitating the classified collection of the shredded materials.

[0019] During operation, by driving the screening assembly 8 to rotate continuously, when the screening assembly 8 is blocked, when the blocked crushed materials are moved to the upper part by the screening assembly 8, due to the gravity of the crushed materials themselves, part of the crushed materials can fall to the bottom to achieve the purpose of preliminary blockage removal. When the crushed materials are stuck inside the screening assembly 8 and difficult to discharge, the knocking assembly 12 can continuously knock the screening assembly 8, so that the screening assembly 8 can shake off the stuck crushed materials, achieving the purpose of automatic blockage removal without affecting the normal operation of the equipment, which is beneficial to improving the processing efficiency of traditional Chinese medicine raw materials.

[0020] As a further solution of the present invention, the crushing assembly 4 includes a driving mechanism 401. The driving mechanism 401 is composed of a gear set and a motor. A crushing roller 402 is fixed on one side of the gear set. The crushing roller 402 is installed inside the crushing box 1.

The material guiding hopper 6 communicates with the crushing box 1 and the multi-stage sieve cylinder 801. A spiral blade 702 is fixed outside the connecting shaft 701. The spiral blade 702 is located in the material guiding hopper 6. One end of the connecting shaft 701 penetrates through the material guiding hopper 6 and is fixedly connected with a driven gear 703.

[0022] As a further solution of the present invention, the screening assembly 8 includes a multi-stage sieve cylinder 801. A number of first-stage sieve holes 802, second-stage sieve holes 803, third-stage sieve holes 804 and discharge holes 805 are formed on the outer side of the multi-stage sieve cylinder 801. The side wall of the multi-stage sieve cylinder 801 is designed to be inclined to the left, and the diameter of the inner wall of the multi-stage sieve cylinder 801 increases sequentially from right to left.

[0023] The aggregate assembly 10 includes a turnover box 101. The two sides of the outer wall of the multi-stage sieve cylinder 801 are respectively connected to two bearing seats 9. The two bearing seats 9 are respectively installed on both sides of the turnover box 101. During the rotation of the fixed shaft 807, the multi-stage sieve cylinder 801 can be driven to rotate inside the two bearing seats 9 through the support frame 809. The multi-stage sieve cylinder 801 is supported by the bearing seats 9 to improve the stability of the rotation of the multi-stage sieve cylinder 801. The turnover box 101 is fixed in the support legs 5. Discharge hoppers 102 are respectively formed on both sides of the bottom of the turnover box 101. Discharge hoppers 103 are respectively provided on both sides in front of the turnover box 101. When the multi-stage sieve cylinder 801 is working, crushed materials of multiple specifications can be discharged from the multiple discharge hoppers 102 and discharge hoppers 103 respectively, thereby facilitating the classified collection of the crushed materials.

[0024] Due to the fact that the side wall of the multi-stage sieve cylinder 801 is designed to be inclined to the left and the diameter of the inner wall of the multi-stage sieve cylinder 801 increases sequentially from right to left, the multi-stage sieve cylinder 801 can convey the crushed materials to the left during rotation, and the crushed materials can fall into the turnover box 101 through the first-stage sieve holes 802, second-stage sieve holes 803, third-stage sieve holes 804 and discharge holes 805 in sequence, so as to achieve the purpose of multi-stage screening of crushed materials of different specifications.

[0025] During the process of the multi-stage sieve cylinder 801 driving the crushed materials to move, since the multi-stage sieve cylinder 801 is always in a rotating state, when the crushed materials blocked in the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 move to the upper part, due to the gravity of the crushed materials themselves, part of the crushed materials can fall into the bottom inside the multi-stage sieve cylinder 801, thereby preventing the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 from being blocked and affecting the screening effect.

[0026] The drying and cleaning assembly 14 includes a blower 141. The blower 141 is fixedly installed on the fixing frame 11.

The cleaning brush 145 is in contact with the top of the multi-stage sieve cylinder 801; Since the cleaning brush 145 is composed of a plurality of filaments and is of a flexible design, the filaments in the cleaning brush 145 can penetrate the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 outside the multi-stage sieve cylinder 801. When the multi-stage sieve cylinder 801 rotates, the cleaning brush 145 can automatically clean the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804, further improving the clogging removal effect; The gas in the air box 143 is blown from a plurality of air outlet holes 144 opened at the bottom to the multi-stage sieve cylinder 801, cooperating with the cleaning brush 145 to clean the multi-stage sieve cylinder 801 and improving the cleaning effect; The hot air blown out from the air outlet holes 144 enters the inside of the multi-stage sieve cylinder 801 through the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804, and can dry the crushed materials during the movement process, accelerating the water loss speed of the traditional Chinese medicine crushed materials.

[0027] As a further solution of the present invention, three triangular blocks 806 are respectively opened on both sides of the outer wall of the multi-stage sieve cylinder 801, and the distances between the three triangular blocks 806 on the same side are equal; a support frame 809 is fixedly connected inside the multi-stage sieve cylinder 801. A fixed shaft 807 is fixed in the middle of the support frame 809. The outer part of the fixed shaft 807 is installed at the top end of the support leg 5 through a shaft seat. One end of the fixed shaft 807 is fixedly connected with a driven wheel 808, and the driven wheel 808 is connected to the end of the driving wheel 403 through a transmission belt 13.

[0028] During operation, since the fixed shaft 807 is fixed to the multi-stage sieve cylinder 801 through the support frame 809, the fixed shaft 807 can drive the multi-stage sieve cylinder 801 to rotate inside the two bearing seats 9 through the support frame 809 during rotation, thus facilitating the driving of the multi-stage sieve cylinder 801. Moreover, the driven wheel 808 drives the driving gear 704 to rotate through the fixed shaft 807, and the driving wheel 403 drives the spiral blade 702 to rotate through the driven gear 703 and the connecting shaft 701, enabling the multi-stage sieve cylinder 801 and the spiral blade 702 to work synchronously, thereby improving the working stability of the equipment.

[0029] As a further solution of the present invention, the knocking assembly 12 includes a knocking block 121. The bottom of the knocking block 121 is designed in an arc shape and contacts the outer wall of the multi-stage sieve cylinder 801. The top of the knocking block 121 penetrates through the fixing frame 11 and is fixedly connected to a top block 122. Sliding rods 123 are respectively fixed on both sides of the bottom of the top block 122. The sliding rods 123 penetrate and slide in the fixing frame 11. A spring 124 is sleeved outside the sliding rods 123. The two ends of the spring 124 are respectively fixedly connected to the opposite surfaces of the top block 122 and the fixing frame 11.

[0030] The multi-stage sieve cylinder 801 drives a plurality of triangular blocks 806 on both sides to rotate. When the inclined surface of the triangular block 806 moves to the position of the knocking block 121, due to the arc-shaped design of the bottom of the knocking block 121, the inclined surface part of the triangular block 806 can squeeze the knocking block 121, and the position of the knocking block 121 can be automatically adjusted to facilitate the subsequent knocking work of the knocking block 121. When the triangular block 806 disengages from the knocking block 121, the top block 122 is driven to move downward by the pulling force of the spring 124, enabling the top block 122 to drive the knocking block 121 to quickly move downward and knock on the multi-stage sieve cylinder 801, causing the multi-stage sieve cylinder 801 to vibrate and shake off the crushed materials, facilitating the blockage removal of the primary sieve holes 802, secondary sieve holes 803, and tertiary sieve holes 804 on the multi-stage sieve cylinder 801.

[0031] A usage method of a raw material crushing equipment for traditional Chinese medicine processing, the usage method includes the following steps: When crushing and processing traditional Chinese medicine raw materials, add the raw materials into the crushing box 1 to make them contact with the crushing assembly 4. Control the driving mechanism 401 to work so that the gear set drives the crushing roller 402 to rotate, and crush the raw materials by extrusion through the crushing roller 402, causing the crushed raw materials to fall into the blanking box 2. Due to the inclined design of the bottom of the blanking box 2, the crushed materials inside the blanking box 2 can slide to the lower discharge port 3 and fall into the guiding hopper 6. During the rotation of the crushing roller 402, it can drive the rotation of the driving wheel 403 at the end. The driving wheel 403 drives the rotation of the driven wheel 808 through the transmission belt 13. The driven wheel 808 drives the rotation of the driving gear 704 through the fixed shaft 807. The driving wheel 403 drives the rotation of the spiral blade 702 through the driven gear 703 and the connecting shaft 701. During the rotation of the spiral blade 702, it can send the crushed materials from the feeding hopper 6 into the multi-stage sieve cylinder 801. Since the fixed shaft 807 is fixed to the multi-stage sieve cylinder 801 through the support frame 809, the fixed shaft 807 can drive the multi-stage sieve cylinder 801 to rotate inside the two bearing seats 9 during rotation, and the multi-stage sieve cylinder 801 is supported by the bearing seats 9 to improve the stability of the rotation of the multi-stage sieve cylinder 801; Since the side wall of the multi-stage sieve cylinder 801 is designed to be inclined to the left, and the diameter of the inner wall of the multi-stage sieve cylinder 801 increases sequentially from right to left, the multi-stage sieve cylinder 801 can convey the crushed materials to the left during rotation. The crushed materials are first screened through the first-stage sieve holes 802. The small-particle crushed materials can fall into the turnover box 101 through the first-stage sieve holes 802 and be discharged from the rightmost discharge hopper 102. When the crushed materials move to the middle of the multi-stage sieve cylinder 801, the second-stage sieve holes 803 can screen the crushed materials. The medium-particle crushed materials can fall into the turnover box 101 through the second-stage sieve holes 803 and be discharged from the right discharge hopper 103. As the crushed materials continue to move to the left, the third-stage sieve holes 804 can screen the crushed materials again. The screened large-particle crushed materials can fall into the turnover box 101 and be discharged from the left discharge hopper 102. As the multi-stage sieve cylinder 801 drives the crushed materials to continue moving to the left, some of the crushed materials that cannot be screened are discharged through the discharge holes 805 and are discharged from the discharge hopper 103 at the left bottom of the turnover box 101. Therefore, the purpose of multi-stage screening and collection of crushed materials of different specifications can be achieved; During the process of the multi-stage sieve cylinder 801 driving the crushed materials to move, since the multi-stage sieve cylinder 801 is always in a rotating state, when the crushed materials blocked in the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 move to the upper part, due to the gravity of the crushed materials themselves, part of the crushed materials can fall into the bottom inside the multi-stage sieve cylinder 801, thereby preventing the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 from being blocked and affecting the screening effect. When the crushed materials are stuck in the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes 804 and are difficult to discharge, the multi-stage sieve cylinder 801 drives a plurality of triangular blocks 806 on both sides to rotate. When the inclined surface of the triangular block 806 moves to the position of the knocking block 121, since the bottom of the knocking block 121 is designed in an arc shape, the inclined surface part of the triangular block 806 can squeeze the knocking block 121, causing the knocking block 121 to drive the sliding rod 123 to move upward through the top block 122, and the top plate stretches the spring 124. When the triangular block 806 rotates and disengages from the knocking block 121, the pulling force of the spring 124 drives the top block 122 to move downward, enabling the top block 122 to drive the knocking block 121 to quickly move downward and knock on the multi-stage sieve cylinder 801, causing the multi-stage sieve cylinder 801 to vibrate and shake off the crushed materials in the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes. As the multi-stage sieve cylinder 801 drives the triangular block 806 to continuously rotate, the knocking block 121 can intermittently knock on the multi-stage sieve cylinder 801 to achieve the purpose of automatically clearing the blockage of the multi-stage sieve cylinder 801; During the rotation of the multi-stage sieve cylinder 801, the cleaning brush 145 at the bottom of the air box 143 can contact the top of the multi-stage sieve cylinder 801. Since the cleaning brush 145 is composed of several filaments and is designed to be flexible, the filaments in the cleaning brush 145 can penetrate the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes outside the multi-stage sieve cylinder 801. When the multi-stage sieve cylinder 801 rotates, the cleaning brush 145 can automatically clean the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes, further improving the blockage clearing effect. At the same time, the blower 141 is started. The blower 141 can work to introduce gas into the air box 143 through the air duct 142. The gas in the air box 143 is blown from a plurality of air outlet holes 144 opened at the bottom to the multi-stage sieve cylinder 801, cooperating with the cleaning brush 145 to clean the multi-stage sieve cylinder 801 and improving the cleaning effect. Moreover, the hot air can also enter the inside of the multi-stage sieve cylinder 801 through the first-stage sieve holes 802, second-stage sieve holes 803, and third-stage sieve holes, and can dry the crushed materials during the movement process, accelerating the water loss speed of the traditional Chinese medicine crushed materials.

8. A method for using a raw material crushing device for traditional Chinese medicine processing, according to any one of claims 1-7, a raw material crushing device for traditional Chinese medicine processing, characterized in that, The usage method includes the following steps: When processing traditional Chinese medicine raw materials by crushing, the raw materials are added into the crushing box (1) to contact with the crushing assembly (4). The driving mechanism (401) is controlled to work so that the gear set drives the crushing roller (402) to rotate. The raw materials are crushed by extrusion through the crushing roller (402), and the crushed raw materials fall into the blanking box (2). Due to the inclined design of the bottom of the blanking box (2), the crushed materials inside the blanking box (2) can slide to the lower discharge port (3) and fall into the guiding hopper (6). During the rotation of the crushing roller (402), the driving wheel (403) at the end can be driven to rotate. The driving wheel (403) drives the driven wheel (808) to rotate through the transmission belt (13). The driven wheel (808) drives the driving gear (704) to rotate through the fixed shaft (807). The driving wheel (403) drives the spiral blade (702) to rotate through the driven gear (703) and the connecting shaft (701). During the rotation of the spiral blade (702), the crushed materials can be sent from the guiding hopper (6) into the multi-stage sieve cylinder (801). Since the fixed shaft (807) is fixed to the multi-stage sieve cylinder (801) through the support frame (809), the fixed shaft (807) can drive the multi-stage sieve cylinder (801) to rotate inside the two bearing seats (9) through the support frame (809) during rotation. The multi-stage sieve cylinder (801) is supported by the bearing seats (9) to improve the rotation stability of the multi-stage sieve cylinder (801). Since the side wall of the multi-stage sieve cylinder (801) is designed to be inclined to the left and the inner diameter of the inner wall of the multi-stage sieve cylinder (801) increases sequentially from right to left, the multi-stage sieve cylinder (801) can convey the crushed materials to the left during rotation. The crushed materials are first screened through the first-stage sieve holes (802). The small-particle crushed materials can pass through the first-stage sieve holes (802) and fall into the turnover box (101) and are discharged from the rightmost blanking hopper (102). When the crushed materials move to the middle of the multi-stage sieve cylinder (801), the second-stage sieve holes (803) can screen the crushed materials. The medium-particle crushed materials can pass through the second-stage sieve holes (803) and fall into the turnover box (101) and are discharged from the right discharge hopper (103). As the crushed materials continue to move to the left, the third-stage sieve holes (804) can screen the crushed materials again. The screened large-particle crushed materials can fall into the turnover box (101) and are discharged from the left blanking hopper (102). As the multi-stage sieve cylinder (801) drives the crushed materials to continue moving to the left, some of the crushed materials that cannot be screened are discharged through the discharge holes (805) and are discharged from the discharge hopper (103) at the left bottom of the turnover box (101). Therefore, the purpose of multi-stage screening and collection of crushed materials of different specifications can be achieved. During the process of the multi-stage sieve cylinder (801) driving the crushed materials to move, since the multi-stage sieve cylinder (801) is always in a rotating state, when the crushed materials blocked in the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804) move to the upper part, due to the gravity of the crushed materials themselves, part of the crushed materials can fall into the bottom inside the multi-stage sieve cylinder (801), thereby preventing the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804) from being blocked and affecting the screening effect. When the crushed materials are stuck in the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804) and are difficult to discharge, the multi-stage sieve cylinder (801) drives a plurality of triangular blocks (806) on both sides to rotate. When the inclined surface of the triangular block (806) moves to the position of the knocking block (121), since the bottom of the knocking block (121) is arc-shaped, the inclined surface part of the triangular block (806) can squeeze the knocking block (121), so that the knocking block (121) drives the sliding rod (123) to move upward through the top block (122), and the top plate stretches the spring (124). When the triangular block (806) rotates and disengages from the knocking block (121), the top block (122) is driven to move downward by the pulling force of the spring (124), so that the top block (122) can drive the knocking block (121) to quickly move downward and knock on the multi-stage sieve cylinder (801), causing the multi-stage sieve cylinder (801) to vibrate and shake off the crushed materials in the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804). As the multi-stage sieve cylinder (801) drives the triangular block (806) to continuously rotate, the knocking block (121) can intermittently knock on the multi-stage sieve cylinder (801) to achieve the purpose of automatically unclogging the multi-stage sieve cylinder (801); During the rotation of the multi-stage sieve cylinder (801), the cleaning brush (145) at the bottom of the air box (143) can contact the top of the multi-stage sieve cylinder (801). Since the cleaning brush (145) is composed of several filaments and is flexibly designed, the filaments in the cleaning brush (145) can penetrate the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804) outside the multi-stage sieve cylinder (801). When the multi-stage sieve cylinder (801) rotates, the cleaning brush (145) can automatically clean the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804), further improving the unclogging effect. At the same time, the blower (141) is started. The blower (141) can work to introduce gas into the air box (143) through the air duct (142). The gas in the air box (143) blows towards the multi-stage sieve cylinder (801) from a plurality of air outlet holes (144) opened at the bottom, cooperating with the cleaning brush (145) to clean the multi-stage sieve cylinder (801) and improving the cleaning effect. Moreover, the hot air can enter the inside of the multi-stage sieve cylinder (801) through the first-stage sieve holes (802), second-stage sieve holes (803) and third-stage sieve holes (804), and can dry the moving crushed materials, accelerating the water loss rate of the traditional Chinese medicine crushed materials.
