DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.
[0024] Example:
[0025] Reference Figure 1-6As shown, the biological gene extraction and grinding device includes a shell body 1, a cover shell 2 is installed on the upper cover of the shell body 1, a rotating motor 3 is fixedly installed on the top surface of the cover shell 2, a fixed gear ring 5 is fixedly installed in the cover shell 2, a rotating circular plate 4 is rotatably installed on the bottom surface of the cover shell 2, two rotating shafts 6 are rotatably installed on the rotating circular plate 4, the rotating shafts 6 extend into the shell body 1, a plurality of crushing rollers 7 are fixedly installed on the rotating shafts 6, a driving gear 8 is fixedly installed on the top end of the rotating shafts 6, the driving gear 8 is meshed with the fixed gear ring 5, a rotating strip plate 9 is rotatably installed in the cover shell 2, the top surface of the rotating strip plate 9 is fixedly connected to the driving end of the rotating motor 3, and the driving gear 8 is rotatably connected to the bottom surface of the rotating strip plate 9.
[0026] The connection between the driving end of the rotating motor 3 and the rotating strip 9 is located at the center of the top surface of the rotating strip 9, and the connection between the driving gear 8 and the rotating strip 9 is located at both ends of the bottom surface of the rotating strip 9, so that the rotating strip 9 can drive the two driving gears 8 to rotate synchronously.
[0027] A side wall scraper 10 matching the inner wall surface of the shell 1 is fixedly installed at the bottom end of the rotating circular plate 4. When the rotating circular plate 4 rotates, the side wall scraper 10 is driven to rotate, and the side wall scraper 10 scrapes the inner wall surface of the shell 1 to prevent the powder generated by grinding from being adsorbed on the inner wall surface of the shell 1.
[0028] The bottom end of the rotating shaft rod 6 is slidably installed with a bottom scraper strip 11 that matches the bottom surface of the inner bottom surface of the shell 1. The bottom scraper strip 11 includes a rotating scraper strip 111 and a sliding rod 112. The rotating scraper strip 111 is fixedly connected to the sliding rod 112, and the rotating scraper strip 111 is slidably connected to the rotating shaft rod 6. A telescopic spring 113 is fixedly installed on the top of the rotating scraper strip 111, and the other end of the telescopic spring 113 is fixedly connected to the rotating shaft rod 6. A limit block 114 is fixedly installed on the rotating scraper strip 111, and a limit slide groove matching the limit block 114 is provided on the rotating shaft rod 6. The rotating shaft rod 6 and the bottom scraper strip 11 are integrated with the cover shell 2. When the cover shell 2 is installed on the shell 1, the telescopic spring 113 is compressed, so that the sliding rod 112 is in close contact with the bottom surface of the inner wall of the shell 1, so that the rotating shaft rod 6 can rotate and revolve, so that the bottom scraper strip 11 can scrape the bottom surface of the inner wall of the shell 1 to prevent the powder generated by grinding from being adsorbed on the bottom surface of the inner wall of the shell 1.
[0029] The crushing rollers 7 on the two rotating shafts 6 are cross-distributed, which reduces the distance between the crushing rollers 7 and improves the grinding and crushing effect.
[0030] The utility model allows the rotating motor 3 to drive the rotating strip plate 9 to rotate, the rotating strip plate 9 drives the driving gear 8 to rotate, the driving gear 8 drives the rotating shaft 6 to revolve in the shell 1, and the rotating circular plate 4 is also driven by the rotating shaft 6, and the driving gear 8 is meshed with the fixed gear ring 5. When the driving gear 8 revolves, the driving gear 8 also rotates, so that the rotating shaft 6 and the crushing roller 7 not only revolve in the shell 1, but also rotate, so as to grind and crush the materials in the shell 1. At the same time, the rotation of the rotating circular plate 4 also drives the side wall scraping strip 10 to scrape the inner wall surface of the shell 1, and the bottom scraping strip 11 is driven by the rotating shaft 6 to rotate, so as to scrape the bottom surface of the inner wall of the shell 1.
[0031] Under the scraping of the side wall scraper 10 and the bottom scraper 11, no powder particles will be adsorbed on the inner wall of the shell 1, which will not affect the subsequent grinding. It is only necessary to remove the rotating shaft 6 and the crushing roller 7 integrated with the cover shell 2 from the shell 1. This is convenient for exposure to the outside world and is easy to clean, and will not affect the subsequent grinding.
[0032] The above is only a preferred embodiment of the utility model, and does not impose any form of limitation on the utility model. Although the utility model has been disclosed as above in the preferred embodiment, it is not used to limit the utility model. Any technician familiar with this patent can make equivalent replacements or changes based on the technical solution and utility model concept of the utility model without departing from the scope of the technical solution of the utility model, which should be covered within the protection scope of the utility model.
