[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] Example 1

[0025] See also Figure 1-6 A raw material crushing device for pharmaceutical preparation includes a crushing box 1, a feed bracket 2 and fixed legs 3, characterized in that the crushing box 1 has a feed port 4 on the top surface and a discharge port 5 on the bottom surface, the feed bracket 2 is erected above the feed port 4, and a plurality of groups of fixed legs 3 are fixedly connected to the bottom surface of the crushing box 1. The feed bracket 2 is fixedly connected to a feed assembly 6 that can control the feed rate. The crushing box 1 is connected to a crushing assembly 7 for fully crushing the pharmaceutical raw materials. The inner wall of the crushing box 1 is fixedly connected to a feed guide inclined plate 8, and the feed guide inclined plate 8 is located below the crushing assembly 7.

[0026] The feeding assembly 6 includes a feeding hopper 601, a feeding motor 602, a bidirectional threaded rod 603, a guide rod 604 and a control panel 605. The feeding bracket 2 is fixedly connected to the feeding hopper 601, the side of the feeding bracket 2 is fixedly connected to the feeding motor 602, the output shaft of the feeding motor 602 is fixedly connected to the bidirectional threaded rod 603, the inner wall of the feeding bracket 2 is fixedly connected to the guide rod 604, and the left and right sides of the bidirectional threaded rod 603 are both threadedly connected to the control panel 605. The control panel 605 is also slidably connected to the guide rod 604, and the bottom surface of the feeding hopper 601 abuts against the top surface of the control panel 605.

[0027] Pharmaceutical raw materials are placed into feed hopper 601 and feed motor 602 is activated. Based on actual production needs, the direction and speed of feed motor 602 are controlled, and the rotation of bidirectional threaded rod 603 is adjusted, causing control plate 605 to move left and right under the guidance of guide rod 604. When control plate 605 moves to the sides, the opening at the bottom of feed hopper 601 increases, accelerating the feed rate. When control plate 605 moves toward the center, the opening at the bottom of feed hopper 601 decreases, slowing the feed rate. This allows for precise control of the feed rate, ensuring that the raw materials enter crushing box 1 evenly and stably.

[0028] The crushing assembly 7 includes a crushing motor 701, a connecting turntable 702, a connecting sleeve 703, a mounting bracket 704, a mounting frame 705 and a screen 706. The mounting frame 705 is detachably connected to the inner wall of the crushing box 1 through the mounting bracket 704. The screen 706 is fixedly connected to the mounting frame 705. The top surface of the support base is fixedly connected to the crushing motor 701. The output shaft of the crushing motor 701 passes through the crushing box 1 and is fixedly connected to the connecting turntable 702. The bottom surface of the connecting turntable 702 is fixedly connected to the connecting sleeve 703. The bottom surface of the connecting sleeve 703 is rotatably connected to the mounting frame 705.

[0029] The crushing assembly 7 also includes a driving vertical rod 707, a driving bevel gear 708, a driven bevel gear 709, a driven cross bar 710, a spiral blade 711 and an arc scraper 712. The bottom surface of the connecting turntable 702 is also fixedly connected to the driving vertical rod 707, the driving vertical rod 707 is located in the connecting sleeve 703, the lower end of the driving vertical rod 707 is rotatably connected to the mounting frame 705, and a plurality of groups of evenly distributed driving bevel gears 708 are fixedly connected to the driving vertical rod 707. 8. The left and right sides of the driving bevel gear 708 are meshed with driven bevel gears 709. The driven bevel gears 709 are fixedly connected to driven cross bars 710. The driven cross bars 710 pass through the connecting sleeve 703 and are rotatably connected to the connecting sleeve 703. The driven cross bars 710 are fixedly connected to spiral blades 711. The ends of the driven cross bars 710 on the same side are rotatably connected to arc scrapers 712, and the arc scrapers 712 abut against the inner wall of the crushing box 1.

[0030] The crushing assembly 7 further includes a brush 713 . The side surface of the connecting sleeve 703 is fixedly connected with the brush 713 , and the bristles of the brush 713 abut against the sieve 706 .

[0031] When the crushing motor 701 is started, its output shaft rotates the connecting disc 702, which in turn drives the connecting sleeve 703 and the drive vertical rod 707. The driving bevel gear 708 on the drive vertical rod 707 meshes with the driven bevel gear 709, rotating the driven crossbar 710. The spiral blades 711 on the driven crossbar 710 crush the pharmaceutical raw materials entering the crushing chamber 1. During the crushing process, the curved scraper 712, as the connecting sleeve 703 rotates, scrapes off any raw materials adhering to the inner wall of the crushing chamber 1, ensuring that the raw materials are fully crushed. Simultaneously, the brush 713 on the side of the connecting sleeve 703 cleans the screen 706 during rotation, preventing it from clogging and ensuring that the crushed raw materials pass smoothly through the screen 706, achieving particle size screening.

[0032] Example 2

[0033] This embodiment further adds the following improvements on the basis of the first embodiment: a water tank 10 is provided on the side of the crushing box 1 through the support plate 9, a water spray head 11 is fixedly connected to the internal top surface of the crushing box 1, a water pump 12 is provided in the water tank 10, and the water outlet of the water pump 12 is fixedly connected to a water pipe 13, and the end of the water pipe 13 passes through the crushing box 1 and is fixedly connected to the water spray head 11.

[0034] After the crushing is completed, the water pump 12 is started, and the water pump 12 conveys the water in the water tank 10 to the water spray head 11, and the water spray head 11 sprays water to clean the inside of the crushing box 1 to clear the residual materials.

[0035] A movable cavity 14 is opened inside the fixed leg 3, and a movable cylinder 15 is fixedly connected to the top surface of the movable cavity 14. The output end of the movable cylinder 15 is fixedly connected to a movable plate 16. The movable plate 16 is slidably connected to the movable cavity 14, and the bottom surface of the movable plate 16 is fixedly connected to a movable wheel 17.

[0036] To move the device, the cylinder 15 within the fixed leg 3 is activated. The output of the cylinder 15 pushes the movable plate 16 downward, extending the wheels 17 on the bottom of the plate 16 and contacting the ground. The wheels 17 now allow for easy transport and repositioning of the device. Once the device is positioned appropriately, the cylinder 15 is activated, retracting the wheels 17 and allowing the fixed leg 3 to support the device, ensuring stability.

[0037] How it works

[0038] Pharmaceutical raw materials are placed into feed hopper 601 and feed motor 602 is activated. Based on actual production needs, the direction and speed of feed motor 602 are controlled, and the rotation of bidirectional threaded rod 603 is adjusted, causing control plate 605 to move left and right under the guidance of guide rod 604. When control plate 605 moves to the sides, the opening at the bottom of feed hopper 601 increases, accelerating the feed rate. When control plate 605 moves toward the center, the opening at the bottom of feed hopper 601 decreases, slowing the feed rate. This allows for precise control of the feed rate, ensuring that the raw materials enter crushing box 1 evenly and stably.

[0039] When the crushing motor 701 is started, its output shaft rotates the connecting disc 702, which in turn drives the connecting sleeve 703 and the drive vertical rod 707. The driving bevel gear 708 on the drive vertical rod 707 meshes with the driven bevel gear 709, rotating the driven crossbar 710. The spiral blades 711 on the driven crossbar 710 crush the pharmaceutical raw materials entering the crushing chamber 1. During the crushing process, the curved scraper 712, as the connecting sleeve 703 rotates, scrapes off any raw materials adhering to the inner wall of the crushing chamber 1, ensuring that the raw materials are fully crushed. Simultaneously, the brush 713 on the side of the connecting sleeve 703 cleans the screen 706 during rotation, preventing it from clogging and ensuring that the crushed raw materials pass smoothly through the screen 706, achieving particle size screening.

[0040] After the crushing is completed, the water pump 12 is started, and the water pump 12 conveys the water in the water tank 10 to the water spray head 11, and the water spray head 11 sprays water to clean the inside of the crushing box 1 to clear the residual materials.

[0041] To move the device, the cylinder 15 within the fixed leg 3 is activated. The output of the cylinder 15 pushes the movable plate 16 downward, extending the wheels 17 on the bottom of the plate 16 and contacting the ground. The wheels 17 now allow for easy transport and repositioning of the device. Once the device is positioned appropriately, the cylinder 15 is activated, retracting the wheels 17 and allowing the fixed leg 3 to support the device, ensuring stability.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
