Specific Embodiment

[0028] The technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0029] As Figure 1-6 shown, a pulverizing device for plant extraction provided by the present invention includes a pulverizing tank 1. A jetting assembly is arranged at the bottom of the pulverizing tank 1 for jetting the dust in the pulverizing tank 1 towards the top of the pulverizing tank 1. A powder outlet 2 and a powder outlet pipe 3 are arranged on one side of the top of the pulverizing tank 1. A filter 4 is arranged between the powder outlet 2 and the powder outlet pipe 3. Through the filtration of the filter 4, only the dust can enter the powder outlet pipe 3 through the powder outlet 2.

[0030] Inside the crushing tank 1, a rotating shaft 5 is provided. A number of crushing knives 6 are sleeved outside the rotating shaft 5. One side of the rotating shaft 5 is connected to a rotating motor 7. The rotating shaft 5 is driven by the rotating motor 7 to rotate, thereby driving the crushing knives 6 to rotate for crushing.

[0031] Through holes are also provided on the crushing knives 6. When too much material is fed, the plants can pass through the through holes, which can prevent the materials from jamming the operation of the crushing knives during crushing.

[0032] In order to make the crushing device crush thoroughly, when a number of crushing knives 6 are sleeved outside the rotating shaft 5, they should be at least more than two-thirds of the height of the crushing tank 1.

[0033] An air venting disk 8 is provided between the jet component and the crushing tank 1. A number of vent holes 9 with the same diameter are provided on the air venting disk 8. The design of multiple holes can make the airflow distribute more evenly when flowing out. Compared with a single large hole, multiple small holes can reduce the concentration and turbulence of the airflow at the outlet, make the distribution of the airflow in space more uniform, make the gas flow more smoothly during jetting, and reduce the resistance and energy loss caused by the concentration of the airflow.

[0034] To facilitate the maintenance of the air venting disk 8, the air venting disk 8 is detachably connected to the crushing tank 1. A handle 10 for easy disassembly is provided outside the air venting disk 8. An air venting groove 11 is provided on the crushing tank 1, and the air venting disk 8 is inserted into the air venting groove 11.

[0035] In order to prevent the leakage of dust in the crushing tank 1, a sealing strip 12 is provided at the contact position between the air venting disk 8 and the air venting groove 11.

[0036] A scraping brush 17 is provided at the bottom of the rotating shaft 5. The scraping brush 17 contacts the air venting disk 8, which is convenient for the scraping brush 17 to scrape away the substances stuck on the air venting disk 8, making the collection of the jet more smooth.

[0037] A closed jet hood 15 is provided at the bottom of the crushing tank 1. The jet component is installed inside the jet hood 15. The jet component includes a number of jet pipes 16 and a jet motor. The jet pipes 16 are connected to the jet motor. By enclosing the crushing tank 1 and the jet component, the dust can be quickly removed from the powder outlet 2 under the action of air pressure.

[0038] In order to accurately control and optimize the production efficiency, an air valve can also be provided on the air venting disk 8, and an intermittent air venting setting is adopted, so that the flow of gas can be accurately controlled according to the preset time interval or conditions, which is convenient for discharging the crushed dust.

[0039] Working principle

[0040] In a closed pulverization environment, when the jet component jets air, the dust moves towards the powder outlet 2. Since the jetting does not generate too much air flow, the plants fed through the feed inlet 13 will fall, be pulverized by the pulverizing knife 6, and the pulverized dust will be discharged from the powder outlet 2 under the action of the jet component and filtered by the filter 4.

[0041] Subsequently, in order to facilitate the separation of the dust from the air, methods such as centrifugal separation, bag dust removal, and static electricity can be adopted.

[0042] The present utility model is described through preferred embodiments. Those skilled in the art will know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. The present utility model is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application all belong to the scope of protection of the present utility model.
