Abstract
Description
Technical Field
[0001] This utility model belongs to the field of veterinary drug processing technology, and in particular relates to a rapid pulverizing and screening device for veterinary drug raw materials. Background Technology
[0002] Veterinary drugs refer to substances used to prevent, treat, diagnose animal diseases, or purposefully regulate animal physiological functions. They are diverse, encompassing chemical drugs, antibiotics, traditional Chinese medicine (TCM) herbs, and biological products. Among these, TCM herbs, using natural plants, animals, and minerals as raw materials, and based on TCM theory, employ unique processing techniques and formulation principles to achieve unique therapeutic effects, thus occupying an important position in the veterinary drug field. In the processing of TCM herbs, fine pulverization and screening are crucial steps to fully release the effective components and obtain better efficacy. The herbs to be processed are poured into a crushing device, where a cutting blade squeezes and grinds them at high speed. The crushed herbs fall onto a vibrating screen under gravity. The vibrating screen then starts, causing the herbs to bounce continuously on the screen surface through high-frequency vibration. Fine powder of the correct size passes through the screen and is collected, while larger, unqualified particles remain on the screen surface. When a certain amount of substandard medicinal materials accumulate on the sieve, workers need to manually dump them and put them back into the crushing device for secondary crushing to complete the entire crushing and screening process of Chinese medicinal materials. However, the continuous retention of substandard medicinal materials on the vibrating screen will hinder the normal screening of the screen and significantly reduce the screening efficiency of the vibrating screen. The operation of manually collecting and cleaning substandard medicinal materials and performing secondary crushing not only consumes a lot of manpower, but also increases the labor costs in the production process. Utility Model Content
[0003] Based on the above background, the purpose of this utility model is to provide a rapid pulverization and screening device for veterinary drug raw materials.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A rapid pulverizing and screening device for veterinary drug raw materials includes a housing; the housing has a feed inlet at the top right end.
[0006] The top of the box is provided with a first guide plate, which is inclined downward from left to right, and the right end of the first guide plate is connected to the side of the feed inlet.
[0007] The chamber is equipped with a crushing component and a screen. The crushing component is located below the feed inlet and above the right end of the screen.
[0008] The box is equipped with a screen, which is inclined downwards from right to left.
[0009] The bottom of the box is provided with a discharge port;
[0010] The left side of the box has a waste outlet, and the bottom of the waste outlet is at the same level as the bottom left side of the screen.
[0011] A waste hopper is provided on the left side of the box, and the waste hopper is located below the waste inlet;
[0012] A lifting assembly is provided on the left side of the box body, which is used to lift the waste hopper.
[0013] The top left side of the box is equipped with a tilting assembly for tilting the waste hopper.
[0014] Through the above technical solution, the raw material enters the box from the feed inlet, is crushed by the crushing component and falls onto the screen for screening. Qualified particles are sent out from the discharge port at the bottom of the box, while unqualified particles enter the waste hopper from the waste port in the inclined direction of the screen. When the waste hopper is full, the lifting component raises the waste hopper to the top of the box, located at the left end of the first guide plate. Then, the tilting component rotates and tilts the waste hopper to pour the unqualified particles onto the first guide plate and into the box for secondary crushing.
[0015] Furthermore, the crushing component includes a first rotating shaft, two first rotating shafts are rotatably disposed in the housing, and one end of the first rotating shaft extends out of the housing and is coaxially connected to a first gear, the two first gears are meshed together, and a first motor is provided on the side of the housing, the first motor is connected to one of the first rotating shafts;
[0016] The side of the first rotating shaft is provided with a linear array of cutters along its axial direction, and the cutters of the two first rotating shafts are staggered.
[0017] Through the above technical solution, the first motor drives the first rotating shaft to rotate, and the first gear drives another first rotating shaft to rotate, thereby driving the cutter to rotate with the first rotating shaft and chop the raw materials.
[0018] Furthermore, the screen is slidably disposed inside the box, and a vibration motor is provided on the inner wall of the box, with the output end of the vibration motor connected to the screen.
[0019] The above technical solution improves the screening effect of the screen by using a vibrating motor to vibrate the screen.
[0020] Furthermore, the lifting assembly includes a lifting block, which is slidably connected to the left side of the box; the waste hopper is provided with second rotating shafts on both sides, which are rotatably connected to the lifting block;
[0021] The side of the box is provided with a threaded rod, and two threaded rods are symmetrically arranged at both ends of the left side of the box. The lifting block is threadedly connected to the threaded rod.
[0022] By rotating the threaded rod, the lifting block rises along the axial direction of the threaded rod under the limit on the side of the box, thereby driving the waste hopper to rise to the top of the box.
[0023] Furthermore, a protective shell is provided at the lower left side of the box body;
[0024] The lower end of the threaded rod is coaxially provided with a worm gear, and a third rotating shaft is rotatably provided inside the protective shell. Worms are provided at both ends of the third rotating shaft; the worms are meshed with the worm gear.
[0025] One end of the third rotating shaft extends out of the protective shell and is connected to the output end of the third motor;
[0026] The third motor is located on the side of the protective casing.
[0027] Through the above technical solution, the third motor drives the third rotating shaft to rotate, and the worm gears at both ends of the third rotating shaft rotate to drive the worm wheel to rotate, thereby driving the two threaded rods to rotate synchronously, lifting or lowering the waste hopper.
[0028] Furthermore, one end of the second rotating shaft extends out of the lifting block and is connected to a second gear;
[0029] The tilting assembly includes a rack that is slidably disposed on the side of the housing.
[0030] The housing is equipped with a cylinder, and the output end of the cylinder is connected to a rack.
[0031] With the above technical solution, when the waste hopper is raised to the top of the box, the cylinder drives the rack to slide down and mesh with the second gear. As the rack moves, the second gear rotates, causing the waste hopper to rotate and pour the particles into the first guide plate.
[0032] Furthermore, a second guide plate is provided on the side of the box body. The second guide plate is rotatably disposed at the bottom of the waste outlet and is open or closed relative to the waste outlet.
[0033] When the second guide plate is in the open state, the second guide plate is tilted downward from right to left, and the left end of the second guide plate is located above the opening of the waste hopper.
[0034] Through the above technical solution, unqualified particles can be better fed into the waste hopper through the second guide plate. When the waste hopper is full and needs to be raised, the second guide plate can be rotated to close the waste outlet. When the waste hopper falls below the waste outlet, the staff can reopen the second guide plate to guide the material.
[0035] Furthermore, baffles are provided on the top three sides of the box.
[0036] This utility model has the following beneficial effects:
[0037] 1. Raw materials enter the box through the feed inlet, are crushed by the crushing component, and fall onto the screen for screening. Qualified particles are discharged from the discharge port at the bottom of the box, while unqualified particles enter the waste hopper from the waste port at the inclined direction of the screen. When the waste hopper is full, the lifting component raises the waste hopper to the top of the box, located at the left end of the first guide plate. Then, the tilting component rotates and tilts the waste hopper to pour the unqualified particles onto the first guide plate and into the box for secondary crushing. There is no need for manual collection and lifting to the feed inlet, which reduces labor costs.
[0038] 2. The third motor drives the third rotating shaft to rotate, and the worm gears at both ends of the third rotating shaft rotate to drive the worm wheel to rotate, thereby driving the two threaded rods to rotate synchronously, providing better stability for the lifting or lowering of the waste hopper.
