Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material grinders, in particular to a medicinal material grinder for veterinary drug production. Background Art

[0002] Veterinary drugs are substances used to prevent, treat, or diagnose animal diseases, or to purposefully regulate animal physiological functions. During veterinary drug production, a grinder is often used to pulverize the raw materials to increase their surface area, making it easier to extract the active ingredients. This pulverization process also helps ensure a more even mixing of the ingredients, creating finer, more uniform particles.

[0003] The patent with the current announcement number CN220759418U discloses a high-efficiency grinding device for Chinese herbal medicine, including a crushing barrel: a mounting barrel is installed at the bottom of the crushing barrel, and the shafts at both ends of the mounting barrel are rotatably mounted on the upper side of a U-shaped frame. One end of the mounting barrel extends outward from the outside of the U-shaped frame and is mounted with a driven pulley. A first motor is installed at the bottom of the U-shaped frame, and a second motor is installed at the bottom of the mounting barrel. A shaft is installed at the upper end of the second motor. The shaft is located at the bottom of the crushing barrel and is mounted with crushing blades. The shaft is located inside the discharge pipe and is welded with spiral blades. When using the device, the fixing mechanism is first installed on the upper side of the workbench, and the U-shaped frame, i.e., the crushing barrel, is placed on the fixing mechanism and fixed. After fixing, the material to be crushed is placed inside the crushing barrel. The first motor drives the driving pulley to rotate, and the driving pulley will drive the driven pulley and the crushing barrel to rotate through the belt, causing the crushing barrel to rotate left and right.

[0004] However, the above-mentioned crushing device still has the following problems during actual use:

[0005] During the pulverization process of a veterinary drug pulverizer, the high-speed rotating blades within the pulverization chamber exert shear and impact forces on the medicinal materials through a centrifugal field, achieving fine crushing of the medicinal materials. However, the gas-solid two-phase flow formed by the rotating blades can cause some fine particles of powder to adhere to the inner wall of the pulverization chamber or the surface of the screen due to inertia. When the lid is opened, the air pressure in the chamber drops sharply, causing airflow turbulence. The powder originally bound by centrifugal force is instantly dispersed with the airflow, forming secondary dust. This phenomenon not only causes dust pollution in the processing site and increases cleaning and maintenance costs, but also poses a risk of dust inhalation, threatening the respiratory health of operators. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a medicinal material grinder for veterinary drug production, which can collect the raised veterinary drug powder before opening the sealing cover.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1-6A medicinal material grinder for veterinary drug production includes a grinder body 1, a grinding barrel 2 installed at the upper end of the grinder body 1 and a sealing cover 3 installed at the opening of the grinding barrel 2. The sealing cover 3 is fixedly connected to a U-shaped tube 11 on the side close to the grinding barrel 2. A collecting pipe 7 is rotatably connected to the inside of the U-shaped tube 11. The other end of the collecting pipe 7 passes through the top of the sealing cover 3 and is connected to a dust collecting assembly. The upper end of the grinding barrel 2 is connected to an exhaust mechanism, and the input end of the exhaust mechanism is connected to the end of the dust collecting assembly away from the collecting pipe 7. A dust inlet 17 is provided at the end of the collecting pipe 7 close to the U-shaped tube 11.

[0026] like Figures 1 to 6 As shown, when the medicinal material grinder for veterinary drug production of the utility model is used, the veterinary drugs to be crushed are first placed in the crushing barrel 2, and then the sealing cover 3 is covered, and then the grinder body 1 is opened. After the grinder body 1 is started, the crushing blades inside the crushing barrel 2 will crush the veterinary drugs until they become powder, and then the grinder body 1 is closed, and then the power of the grinder body 1 is turned off to stop the crushing blades;

[0027] After the pulverizer body 1 stops, the staff manually moves the collecting pipe 7 toward the direction of the exhaust mechanism. After the dust collecting component at the front end of the collecting pipe 7 is aligned with the exhaust mechanism, the exhaust mechanism is started. At this time, the dust inlet 17 of the collecting pipe 7 is also aligned with the opening of the U-shaped tube 11. After that, the veterinary drug powder floating in the pulverizing barrel 2 can be extracted from the opening of the U-shaped tube 11 through the dust collecting component and the dust inlet 17 of the collecting pipe 7.

[0028] The extracted veterinary drug powder will be blocked and collected by the dust collecting assembly, and then the sealing cover 3 is opened, which can prevent the powder inside the crushing barrel 2 from floating into the air and affecting the environment and staff.

[0029] As a preferred embodiment of the present invention, the exhaust mechanism includes an exhaust pipe 8, a connecting block 12, and a dust collection assembly. One end of the connecting block 12 is fixedly connected to the upper end of the crushing barrel 2, and the other end of the connecting block 12 is fixedly connected to the outer wall of the lower end of the exhaust pipe 8. The dust collection assembly is located inside the exhaust pipe 8, and the upper end of the exhaust pipe 8 abuts against the dust collection assembly. The dust collection assembly includes a cross bracket 18, an exhaust motor 19, and a fan blade 14. The four ends of the cross bracket 18 are fixedly connected to the inner wall of the lower end of the exhaust pipe 8, the middle portion of the cross bracket 18 is fixedly connected to the outer wall of the exhaust motor 19, and the output shaft of the exhaust motor 19 is fixedly connected to the central axis of the fan blade 14.

[0030] More specifically, when the collecting tube 7 rotates and the dust collecting assembly rotates to abut against the upper surface of the exhaust tube 8, the exhaust motor 19 is started. After the exhaust motor 19 is started, its output shaft rotates with the fan blades 14. The fan blades 14 rotate to extract air from the inside of the exhaust tube 8, and then the powder can be extracted through the dust collecting assembly, the collecting tube 7 and the U-shaped tube 11. After the floating powder is sucked away, the powder can be prevented from floating when the sealing cover 3 is opened later.

[0031] It should be noted that a filter is provided inside the exhaust pipe 8 or a collection bag is provided outside the exhaust pipe 8 to intercept and collect the extracted veterinary drug powder.

[0032] As a preferred embodiment of the present invention, the dust collection assembly includes a connecting pipe 5 and a disassembly assembly, one end of the disassembly assembly is connected to the end of the collection pipe 7 away from the U-shaped pipe 11, the other end of the disassembly assembly is connected to one end of the connecting pipe 5, and the other end of the connecting pipe 5 is against the upper surface of the exhaust pipe 8. The disassembly assembly includes a swivel 6 and a T-shaped anti-slip ring 16, the end of the connecting pipe 5 away from the exhaust pipe 8 is provided with a T-shaped anti-slip groove 15, the T-shaped anti-slip ring 16 is rotatably connected to the T-shaped anti-slip groove 15, the end of the T-shaped anti-slip ring 16 away from the T-shaped anti-slip groove 15 is fixedly connected to one end of the swivel 6, and the other end of the swivel 6 is threadedly connected to the collection pipe 7.

[0033] More specifically, by providing a dust collection assembly, an effective connection can be formed between the collection pipe 7 and the exhaust pipe 8. When the fan blades 14 inside the exhaust pipe 8 rotate, the floating powder can be sucked away more conveniently and quickly.

[0034] In addition, when disassembling and cleaning at a later time, it is only necessary to rotate the swivel 6. When the swivel 6 rotates, the T-shaped anti-slip ring 16 can be rotated inside the T-shaped anti-slip groove 15, and during the rotation, the connecting pipe 5 is pushed outward, thereby separating the exhaust pipe 8 from the connecting pipe 5, and then the inside of the connecting pipe 5 and the exhaust pipe 8 can be cleaned.

[0035] As a preferred solution of the present invention, the upper surface of the crushing barrel 2 is fixedly connected to the sealing rail 4, the bottom surface of the connecting pipe 5 near one end of the exhaust pipe 8 is slidingly connected to the sealing rail 4, and a sealing gasket is provided on the contact surface between the connecting pipe 5 and the sealing rail 4.

[0036] More specifically, by providing the sealing rail 4 , firstly, the rotation trajectory of the connecting pipe 5 can be limited to prevent deviation, and secondly, dust will not overflow from here during normal pulverization inside the pulverizing barrel 2 .

[0037] As a preferred solution of the present invention, the upper surface of the sealing rail 4 near one end of the exhaust pipe 8 is fixedly connected to a support block 9, the upper end of the support block 9 is fixedly connected to a self-resetting switch 10, and the side wall of the connecting pipe 5 near one end of the exhaust pipe 8 is fixedly connected to a trigger block 13 that can squeeze the self-resetting switch 10.

[0038] More specifically, by setting the self-resetting switch 10 and the trigger block 13, the exhaust motor 19 will only start after the connecting pipe 5 is rotated to this position so that the trigger block 13 contacts the self-resetting switch 10. It will be in the off state at other times, thereby saving electricity.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
