[0024] Embodiment 1:

[0025] See also Figure 1 The present application provides a dust prevention device for a drug pulverizer, comprising a first discharge pipe 1, a second discharge pipe 4, and a dust prevention cloth belt 9. The first discharge pipe 1 is a discharge pipe of a 40B universal pulverizer.

[0026] The second discharge pipe 4 is sleeved on the lower end of the first discharge pipe 1 , and the two are clearance-matched to form a sliding connection, so that the second discharge pipe 4 can move up and down along the first discharge pipe 1 .

[0027] A first connecting rod 2 is provided at the upper end of the first discharge pipe 1, and a second connecting rod 5 is provided at the upper end of the second discharge pipe 4 which is opposite to the first connecting rod 2. A first spring 6 is provided between the first connecting rod 2 and the second connecting rod 5. Under normal conditions, under the pulling force of the first spring 6, the second discharge pipe 4 is located at a higher position. When necessary, the second discharge pipe 4 can be pulled downward, and then the lower part of the discharge port of the second discharge pipe 4 can be moved to a lower position to facilitate the material to enter the corresponding barrel.

[0028] A strip-shaped toothed limit strip 3 is vertically installed on the side of the first discharge pipe 1. The teeth of the toothed limit strip 3 are in the form of a right-angled triangle, and the right-angled sides of each tooth are located at the bottom. The second discharge pipe 4 is rotatably connected to a pawl 7 used in conjunction with the toothed limit strip 3 through a rotating shaft. The rotating shaft is provided with a second spring for driving the pawl 7 to rotate toward the toothed limit strip 3. When the second discharge pipe 4 is pulled downward, the pawl 7 pops up, so that the second discharge pipe 4 can move downward smoothly. After the second discharge pipe 4 is released, the second discharge pipe 4 moves upward under the elastic force of the first spring 6, and the pawl 7 is stuck in the toothed limit strip 3 under the elastic force of the second spring, thereby achieving the purpose of fixing the position of the second discharge pipe 4; when the second discharge pipe 4 needs to be moved upward and reset again, it only needs to release the pawl 7, and the second discharge pipe 4 can be automatically reset under the elastic action of the first spring 6.

[0029] In order to facilitate the staff to rotate the ratchet 7, a handle is also provided on the ratchet 7.

[0030] The upper end of the dust-proof cloth belt 9 is fixedly connected to the lower end of the second discharge pipe 4, and the lower end of the dust-proof cloth belt 9 is extended downward. When in use, the lower end of the dust-proof cloth belt 9 is directly put on the barrel containing dust materials, which can effectively avoid the problem of dust diffusion outward, and effectively reduce the impact of drug dust on the surrounding environment. At the same time, the drug powder collected in the dust-proof cloth belt 9 can also be shaken back into the corresponding barrel, thereby reducing the problem of related drug production costs.

[0031] Embodiment 2:

[0032] Based on the first embodiment, Figure 2 As shown, the lower end of the second discharge pipe 4 is in a conical funnel shape, so that the powdery material discharged from the second discharge pipe 4 is more concentrated, which is beneficial to reduce the generation of dust.

[0033] In some specific embodiments, a limiting protrusion 10 is provided on the side of the second discharge pipe 4; a first rubber band 11 is provided at the upper end of the dustproof cloth belt 9, and the upper end of the dustproof cloth belt 9 is tied to the top of the limiting protrusion 10 by the first rubber band 11, so that the dustproof cloth belt 9 is firmly connected to the second discharge pipe 4. At the same time, by providing the first rubber band 11, the upper end of the dustproof cloth belt 9 is elastic, thereby facilitating the disassembly and installation of the dustproof cloth belt 9, and the maintenance and use of the dustproof cloth belt 9 are more convenient.

[0034] In some specific embodiments, a second rubber band 8 is provided at the lower end of the dustproof belt 9, so that the lower end of the dustproof belt 9 is elastic, thereby facilitating the staff to easily put the lower end of the dustproof belt 9 onto the corresponding barrel when in use.

[0035] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
