DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 4 As shown, the crushing mechanism 6 includes two first rotating rods 601, which are rotatably connected to the crushing box 2, one end of the two first rotating rods 601 can move through the crushing box 2, two first gears 602 are fixedly sleeved on the outer surfaces of the two first rotating rods 601, and the two first gears 602 are meshingly connected, and two second rotating rods 603 are rotatably connected in the crushing box 2, one end of the two second rotating rods 603 can move through the crushing box 2, two second gears 604 are fixedly sleeved on the outer surfaces of the two second rotating rods 603, and the two second gears 604 are meshingly connected. Through two sets of mutually meshing gear structures, namely the first gear 602 and the second gear 604, the two first rotating rods 601 and the two second rotating rods 603 can achieve relative rotation. When one of the rotating rods rotates, the meshing action of the gears can drive the rotating rod matched with it to rotate in the opposite direction, thereby providing multi-directional rotational power for the crushing process, ensuring that the crushing of the western medicine is more comprehensive and sufficient, and improving the quality and efficiency of the crushing.

[0025] like Figure 4 As shown, the outer surfaces of the two first rotating rods 601 and the two second rotating rods 603 are fixedly connected with crushing blades 605, and one end of one of the first rotating rods 601 and one of the second rotating rods 603 are fixedly connected with two second rotating wheels 606, and the outer surfaces of the two second rotating wheels 606 are transmission-connected with second synchronous belts 607, and the crushing blades 605 directly act on the western medicine to cut and crush it, and the second synchronous belt 607 connects one of the first rotating rods 601 and one of the second rotating rods 603, so that the two rotating rods can rotate in coordination, so that during the crushing process, the crushing blades 605 at different positions can cooperate with each other to perform staggered crushing on the western medicine, further enhancing the crushing effect and reducing the situation of insufficient crushing of the western medicine.

[0026] like Figure 2 and Figure 4As shown, one end of another second rotating rod 603 and one end of the second rotating shaft 405 are fixedly connected with two third rotating wheels 608, and the outer surfaces of the two third rotating wheels 608 are transmission-connected with a third synchronous belt 609. A transmission connection between the second rotating shaft 405 and another second rotating rod 603 is established through the third synchronous belt 609. After the dual-output shaft motor 401 is started and the second electromagnetic clutch 404 is turned on by the PLC controller 8, the power of the second rotating shaft 405 is transmitted to the second rotating rod 603, thereby driving the entire crushing mechanism 6 to operate, so that the crushing mechanism 6 can work continuously and efficiently, and it is also convenient to control the operating state of the crushing mechanism 6 by controlling the dual-output shaft motor 401.

[0027] like Figure 2 and Figure 6 As shown, the dust removal mechanism 7 includes a water tank 701, which is installed on the top of the base plate 1. A dust pump 702 is installed on the top of the base plate 1. A retractable dust pipe 703 is fixedly connected to the top of the cover plate 505. One end of the retractable dust pipe 703 away from the cover plate 505 is fixedly connected to the input end of the dust pump 702. The dust pump 702 cooperates with the retractable dust pipe 703. The retractable dust pipe 703 can adjust its position as the cover plate 505 moves, so as to always maintain effective absorption of the dust in the crushing box 2. The negative pressure generated by the dust pump 702 sucks in the dust generated by the crushing, effectively preventing the dust from flying out of the feed port 3, maintaining the cleanliness of the working environment, reducing the harm of dust to the health of operators, and also avoiding the pollution of dust to surrounding equipment and environment.

[0028] like Figure 2 and Figure 3 As shown, the output end of the dust suction pump 702 is fixedly connected to a delivery pipe 704, and the end of the delivery pipe 704 away from the dust suction pump 702 is connected to the interior of the water tank 701. The dust sucked in by the dust suction pump 702 is delivered to the water tank 701 through the delivery pipe 704, providing a channel for subsequent dust reduction treatment. By introducing dust into the water tank 701, the water level in the water tank 701 is lower than the filter 705, and the dust is treated with the water in the water tank 701, centralized treatment of dust is achieved, secondary diffusion of dust in the air is avoided, and the dust removal effect is further improved.

[0029] like Figure 6As shown, a filter screen 705 is fixedly connected to the water tank 701, a transverse pipe 706 is fixedly installed on the inner top of the water tank 701, and a nozzle 707 is installed at the bottom of the transverse pipe 706. Water is sprayed out through the nozzle 707 to reduce the dust entering the water tank 701, so that the dust is adsorbed by the water and falls. The filter screen 705 filters the water and dust after the dust reduction, and intercepts the dust in the water tank 701. The purified water can be recycled. This structural design ensures the dust reduction and filtering effects in the water tank 701, extends the service life of the water in the water tank 701, and reduces the operating cost of the equipment. At the same time, a movable door is hinged on one side of the water tank 701 to facilitate cleaning of the dust filtered on the filter screen 705.

[0030] like Figure 6 As shown, a water pump 708 is installed on one side of the water tank 701, and the output end of the water pump 708 is fixedly connected to a water pipe 709. The end of the water pipe 709 away from the water pump 708 passes through the water tank 701 and is connected to the interior of the cross pipe 706. The water in the water tank 701 is pumped into the cross pipe 706 by the water pump 708 and then sprayed out through the nozzle 707, thereby realizing the recycling of water. There is no need to frequently replace the water in the water tank 701, thereby improving the practicality and convenience of the equipment.

[0031] like Figure 6 As shown, the input end of the water pump 708 is fixedly connected to a pumping pipe 710, and the end of the pumping pipe 710 away from the water pump 708 is connected to the interior of the water tank 701. The pumping pipe 710 provides a stable water source for the water pump 708, ensuring that the water pump 708 can continuously pump out the water in the water tank 701 and transport it to the horizontal pipe 706, thereby ensuring the normal water spraying of the nozzle 707.

[0032] like Figure 2 and Figure 3 As shown, one side of the crushing box 2 is fixedly connected to one side of the water tank 701 by two discharge pipes 9, and two control valves 10 are installed on the two discharge pipes 9. The discharge pipes 9 and the control valves 10 facilitate the discharge of the crushed western medicine in the crushing box 2 and the treated water in the water tank 701, and the control valves 10 facilitate opening and closing of the discharge pipes 9.

[0033] The method of use and working principle of the device: When in use, in the initial state, the feed port 3 is in a closed state, the dual-output shaft motor 401 is started and the first electromagnetic clutch 402 is turned on through the PLC controller 8, the first output shaft of the dual-output shaft motor 401 drives the first rotating shaft 403 to rotate, the first rotating shaft 403 drives the threaded rod 502 to rotate through the first rotating wheel 506 and the first synchronous belt 507, the fixed rod 503 limits the movable plate 504, so that the threaded rod 502 rotates to make the two movable plates 504 move along the threaded rod 502 and the fixed rod 503, thereby driving the cover plate 505 to move, when the movable plate 504 moves to contact with the first sensor 508, the first sensor 508 feeds back a signal to the PLC controller 8, and the PLC controls After receiving the signal, the device 8 turns off the dual output shaft motor 401, and the feed port 3 is opened at this time. Then, the western medicine to be crushed is poured into the crushing box 2 from the feed port 3, and then the dual output shaft motor 401 is started to reverse through the PLC controller 8. The first output shaft of the dual output shaft motor 401 drives the first rotating shaft 403 to rotate in the opposite direction, and the threaded rod 502 is rotated in the opposite direction through the first rotating wheel 506 and the first synchronous belt 507. The two moving plates 504 drive the cover plate 505 to move in the opposite direction. When the moving plate 504 moves to contact with the second sensor 509, the second sensor 509 feeds back the signal to the PLC controller 8. After receiving the signal, the PLC controller 8 turns off the dual output shaft motor 401 and disconnects the first electromagnetic clutch 402. At this time, the feed port 3 is closed, and then The dual output shaft motor 401 is started by the PLC controller 8 and the second electromagnetic clutch 404 is turned on. The second output shaft of the dual output shaft motor 401 drives the second rotating shaft 405 to rotate. The second rotating shaft 405 drives another second rotating rod 603 to rotate through the third rotating wheel 608 and the third synchronous belt 609. The second rotating rod 603 drives one of the second rotating rods 603 to rotate in the opposite direction through the second gear 604. At the same time, one of the second rotating rods 603 drives one of the first rotating rods 601 to rotate through the second rotating wheel 606 and the second synchronous belt 607. The first rotating rod 601 then drives another first rotating rod 601 to rotate in the opposite direction through the first gear 602, so that the crushing blades 605 on the four rotating rods rotate to cut the western medicine entering the crushing box 2. Cutting and crushing. During the crushing operation, the dust suction pump 702 is started through the PLC controller 8. The dust suction pump 702 generates negative pressure, and the dust generated by the crushing in the crushing box 2 is sucked in through the retractable dust suction tube 703. The dust enters the water tank 701 through the conveying pipe 704. At the same time, the PLC controller 8 starts the water pump 708. The water pump 708 draws out the water in the water tank 701 through the pumping pipe 710, and conveys the water to the horizontal pipe 706 through the water conveying pipe 709, and then sprays it out from the nozzle 707. The dust entering the water tank 701 is subjected to dust reduction treatment. The water and dust after dust reduction are filtered through the filter 705, and the filtered water remains in the water tank 701 and can be recycled. After the crushing is completed, the control valve 10 on the discharge pipe 9 on one side of the crushing box 2 is opened to discharge the crushed western medicine.
