[0022] The present invention adopts an annular collection box 1 with a V-shaped cross-section to collect fallen medicinal powder. The medicinal powder can be guided to the discharge hole 11 by the cooperation of the guiding inclined surface 13 and the inner inclined surfaces on both sides of the annular collection box 1. When the medicinal powder needs to be discharged, the solenoid valve 121 on the L-shaped discharge pipe 12 works, and then the medicinal powder is introduced into the cloth bottle body 123 through the gas recoil device 5. The cloth bottle body 123 has the same function as the cloth bag 3. By removing the connecting piece 122, the medicinal powder in the cloth bottle body 123 can be poured out, which is very convenient. The cloth bag 3 can be knocked by the knocking mechanism 6, so that the medicinal powder attached to the inner wall of the cloth bag 3 can fall off, thereby avoiding regional blockage of the cloth bag 3.

[0023] The extended connecting plate 15 is fixed to the external frame by bolts, and the feed pipe 2 and the discharge pipe 41 are connected to the external hot air drying system. During the drying process of the Chinese medicinal materials by the external hot air drying system, the hot air carries the powder into the feed pipe 2, and then enters the cloth bag 3. The cloth bag 3 can be knocked by the knocking mechanism 6. The knocking mechanism 6 includes a lifting tube 61 and a knocking component 62 that can knock the support rod 14 as the lifting tube 61 rises and falls. A cone head cover 63 is provided on the top of the lifting tube 61.

[0024] Furthermore, the knocking assembly 62 includes a plurality of knocking components arranged at equal angles around the lifting tube 61. The knocking components include a screw seat 621 and a guide block 622. The screw seat 621 is screwed with a suspension rod 623. The head end of the suspension rod 623 is provided with a telescopic cylinder 624. The telescopic cylinder 624 is provided with a telescopic groove 6241. A synchronous block 625 is provided in the telescopic groove 6241. The head end of the synchronous block 625 is provided with an abutment rod 626. The head end of the abutment rod 626 is provided with an abutment block 627. The abutment block 627 is provided with two upper and lower opposite A first wedge surface 6271 is provided, a spring 6251 is provided at the tail end of the synchronization block 625, a removable cover 6242 is provided at the head end of the telescopic cylinder 624, and a through-hole is provided on the cover 6242 for the abutment rod 626 to pass through. The guide block 622 is provided with two second wedge surfaces 6221 which are symmetrically arranged up and down and cooperate with the first wedge surface 6271. The screw seat 621 is horizontally arranged on the outer wall of the lifting tube 61, and the guide block 622 is arranged on the inner wall of the support rod 14. The installation heights of the guide blocks 622 of multiple knocking components are inconsistent.

[0025] Furthermore, the opening assembly 64 includes a fitting sealing plate 641, a hinged rod 642 is provided at the top end of the back of the fitting sealing plate 641, a hinged shaft 643 is provided at one end of the hinged rod 642, a blocking rod 644 is provided perpendicular to the outer wall of one end of the hinged shaft 643, a hinged seat 632 and a limiting rod 633 which is vertically arranged and used to block the blocking rod 644 are provided at the top of the cone head cover 63, the limiting rod 633 is located next to the hinged seat 632, and the hinged shaft 643 is hinged to the hinged seat 632.

[0026] Furthermore, the driving assembly 65 includes a rotating seat 651, a transmission tube 652 and a driving shaft 653. A plurality of mounting rods 6511 are provided on the outer wall of the rotating seat 651, a protrusion is provided on the inner wall of the transmission tube 652, a second turntable 654 is provided at the bottom of the driving shaft 653, and a plurality of second blades 6541 are arranged at equal angles around its circumference are provided on the second turntable 654. An oblique annular guide groove 6531 is provided on the outer wall of the driving shaft 653 for guiding the protrusion to reciprocate and rise and fall as it rotates. The mounting rod 6511 is connected to the inner wall of the feeding pipe 2, and the top of the transmission tube 652 is fixedly connected to the inner top wall of the cone head cover 63. The driving shaft 653 is rotatably set on the rotating seat 651, and the driving shaft 653 is slidably set in the transmission tube 652.

[0027] The hot air carries the powder into the feed pipe 2, and then the hot air flows into all the exhaust windows 631. The hot air impacts the sealing plate 641, and the sealing plate 641 flips around the axis of the hinge shaft 643. Then the hot air can enter the interior of the cloth bag 3, and the blocking rod 644 on the hinge shaft 643 gradually abuts against the limiting rod 633, so that the sealing plate 641 cannot continue to rotate, that is, the rotation angle of the sealing plate 641 is limited. In the process of rapid flow of hot air, the second turntable 654 rotates because the second blade 6541 is impacted by the flowing hot air, and the second The turntable 654 drives the driving shaft 653 to rotate synchronously. The oblique annular guide groove 6531 on the driving shaft 653 can drive the protrusion to move up and down on it. The protrusion drives the transmission tube 652 to move up and down on the driving shaft 653. The transmission tube 652 drives the cone head cover 63 to move up and down. The cone head cover 63 drives the lifting tube 61 to move up and down on the feeding tube 2. The vertical slide groove and the vertical slide bar 21 cooperate to prevent the lifting tube 61 from deflecting during the lifting process. During the lifting process, the lifting tube 61 also drives the knocking component 62 to knock the cloth bag 3 synchronously.

[0028] When the lifting tube 61 rises, the lifting tube 61 drives the screw seat 621, the hanging rod 623, the telescopic cylinder 624, the abutting rod 626 and the abutting block 627 to rise synchronously, and the first wedge surface 6271 at the upper end of the abutting block 627 gradually conflicts with the second wedge surface 6221 at the lower end of the guide block 622. Then, the abutting block 627 moves toward the screw seat 621 through the cooperation of the first wedge surface 6271 and the second wedge surface 6221. The abutting block 627 drives the abutting rod 626 to move synchronously, and the abutting rod 626 drives the synchronous block 625 to retract into the telescopic groove 6241. In order to prevent the two first wedge surfaces 6271 on the abutting block 627 from being misaligned due to the deflection of the synchronous block 625, the telescopic groove 6241 is tightened. 6241 is set to have a polygonal cross-section. At the same time, the spring 6251 is compressed, and the first wedge surface 6271 at the upper end of the abutment block 627 gradually separates from the second wedge surface 6221 at the lower end of the guide block 622. Then the spring 6251 drives the synchronization block 625 to move in the opposite direction through the elastic force, and the synchronization block 625 drives the abutment rod 626 and the abutment block 627 to move in the opposite direction. The abutment block 627 hits the corresponding support rod 14, and the support rod 14 generates a shaking force, which is then transmitted to the cloth bag 3. The guide blocks 622 on all the knocking components are inconsistent in height, so that different height areas of the cloth bag 3 can be subjected to the shaking force. Of course, the downward movement of the lifting tube 61 can also generate a shaking force on the cloth bag 3, thereby avoiding regional blockage of the cloth bag 3.

[0029] After the powder in the hot air is filtered out by the cloth bag 3, the hot air is discharged from the discharge pipe 41. However, some powder will still adhere to the cloth bag 3. Therefore, a gas recoil device 5 is provided to clean it thoroughly to facilitate the collection of the powder.

[0030] The gas recoil device 5 includes a gas storage tank 51, a jet ring tube 52 and a transmission assembly 53 for driving the jet ring tube 52 to rise and fall. An outlet pipe 511 is provided on the top of the gas storage tank 51, and an electromagnetic valve 121 is provided on the outlet pipe 511. A pressurized suction pump 512 is provided at the bottom of the gas storage tank. A jet head group is provided on the inner side of the jet ring tube 52. Two connecting brackets 42 are provided on the outer wall of the closed cover body 4. The gas storage tank 51 is connected to the two connecting brackets 42. The jet ring tube 52 is located between the outer wall of the cloth bag 3 and the inner wall of the closed cover body 4. The transmission assembly 53 is arranged on the closed cover body 4, and the jet ring tube 52 is connected to the transmission assembly 53.

[0031] Furthermore, the transmission assembly 53 includes an air transmission tube 531, a bidirectional screw 532 and a guide rod 533. The side wall of the air transmission tube 531 is provided with an external box 534 connected thereto. The external box 534 is provided with a first rotary disk 535. The first rotary disk 535 is provided with a plurality of first blades 536 arranged at equal angles around its circumference. The two sides of the jet ring tube 52 are respectively provided with a screw seat that cooperates with the bidirectional screw 532 and a guide seat that cooperates with the guide rod 533. The top of the jet ring tube 52 is provided with a There is an air inlet 521, and a connecting pipe 43 is provided on the top of the closed cover body 4. One end of the air transfer pipe 531 is connected to the air outlet pipe 511. The bidirectional screw 532 is rotatably set on the closed cover body 4 and the extended connecting plate 15, and the top of the bidirectional screw 532 is fixedly connected to the bottom of the first turntable 535. The guide rod 533 is fixedly connected to the inner top wall of the closed cover body 4. The top of the connecting pipe 43 is connected to the air transfer pipe 531, and the bottom of the connecting pipe 43 is connected to the air inlet 521 through a bellows.

[0032] Furthermore, the nozzle group includes multiple nozzles 522 arranged at equal angles around the circumference of the nozzle ring tube 52. The nozzles 522 are arranged at an angle. There are two nozzle groups, and the two nozzle groups are symmetrically arranged on the inner side of the nozzle ring tube 52.

[0033] Furthermore, the gas recoil device 5 also includes a plurality of knocking components 54, which are arranged on the jet ring tube 52 at equal angles around the circumference of the jet ring tube 52. The knocking components 54 include a knocking rod 541 and a guide rod 542. The tail end of the knocking rod 541 is provided with a U-shaped frame 543, and the U-shaped frame 543 is provided with a transmission rod 544. The guide rod 542 is provided with a wavy guide groove 5421 that slides with the transmission rod 544. The bottom of the jet ring tube 52 is provided with a sliding seat 523 that slides with the knocking rod 541, and the head end of the knocking rod 541 is in contact with the outer wall of the cloth bag 3.

[0034] Close the discharge pipe 41 and the feed pipe 2, then open the solenoid valve 121 on the L-shaped discharge pipe 12 and the solenoid valve 121 on the air outlet pipe 511. Of course, the sealing plate 641 rotates in the opposite direction due to its own gravity, and then the sealing plate 641 closes the exhaust window 631, which can prevent dust from falling into the feed pipe 2. The high-pressure gas stored in the gas storage tank 51 is discharged from the air outlet pipe 511, and then the high-pressure gas enters the air transfer pipe 531. When the high-pressure gas flows in the air transfer pipe 531, it impacts the first blade 536. After being impacted, the first blade 536 drives the first turntable 535 to rotate, and the first turntable 535 drives the bidirectional screw 532 to rotate. Through the cooperation between the bidirectional screw 532 and the screw seat, and the cooperation between the guide rod 533 and the guide seat, the jet ring tube 52 can move back and forth in a horizontal state. At the same time, the high-pressure gas can enter the bellows through the connecting pipe 43, and then enter the jet ring tube 52 through the air inlet 521. Then the high-pressure gas is ejected through the nozzle 522. The high-pressure gas can directly act on the outer wall of the cloth bag 3, and then the dust attached to the inner wall of the cloth bag 3 can fall off. Since the pressure inside the closed cover body 4 is lower than the external pressure, the high-pressure gas carries the dust that falls into the annular collection box 1 and is quickly discharged from the discharge hole 11. The dust is then filtered and collected through the cloth bottle body 123, and the gas is discharged to the outside.

[0035] In order to increase the area on which the high-pressure gas acts on the outer wall of the cloth bag 3, two groups of nozzles are provided, one group of nozzles 522 is tilted upward, and the other group of nozzles 522 is tilted downward, thereby invisibly expanding the effective area.

[0036] During the up and down reciprocating movement of the jet ring tube 52, all the tapping components 54 also work synchronously and continuously. The jet ring tube 52 drives the sliding seat 523 to move up and down synchronously. The sliding seat 523 drives the tapping rod 541, the U-shaped frame 543 and the transmission rod 544 to move synchronously. The transmission rod 544 moves back and forth through the wavy guide groove 5421. The transmission rod 544 drives the U-shaped frame 543 to move back and forth synchronously. The U-shaped frame 543 drives the tapping rod 541 to move back and forth synchronously. The tapping rod 541 continuously taps the cloth bag 3 to generate shaking force, so that the dust attached to the cloth bag 3 can be thoroughly cleaned.
