[0018] In order to make the technical means, creative features, objectives and effects of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0020] Example 1

[0021] like Figure 1-3 As shown, a food testing sample grinding device includes a shell 1, a base 2 is provided on the outer side of the bottom end of the shell 1, a motor Ⅰ7 and a motor Ⅱ8 are respectively provided at the inner top end of the shell 1 and the inner bottom end of the base 2, a connecting shaft is provided at the bottom end of the motor Ⅰ7, a grinding disk Ⅱ4 is provided at the bottom end of the connecting shaft, and a grinding disk Ⅰ3 in contact with the shell 1 and the grinding disk Ⅱ4 is provided at the top end of the motor Ⅱ8 and located on the inner side of the base 2.

[0022] The connecting shaft includes a connecting rod 9 connected to the bottom end of the motor I7, a sleeve 5 sleeved on the outside of the connecting rod 9 and connected to the grinding disk II4, and a spring 6 sleeved on the outside of the sleeve 5 and the connecting rod 9 and connected to the shell 1 and the grinding disk II4. The middle part of the sleeve 5 is hollow, the cross-section of the connecting rod 9 is rectangular, and the connecting rod 9 is inserted in the middle part of the sleeve 5. The spring 6 is compressed after the base 2 is installed on the shell 1, so that the spring 6 drives the grinding disk II4 to move downward and contact the grinding disk I3, and through the sleeve 5 and the connecting rod 9, the motor I7 can drive the grinding disk II4 at different positions to rotate.

[0023] A groove is provided in the middle of grinding disk I3, and the outer size of grinding disk II4 is matched with the inner size of grinding disk I3. A plurality of protrusions are provided on the inner side of the groove of grinding disk I3 and the bottom end of grinding disk II4. The protrusions of grinding disk I3 and grinding disk II4 are arranged alternately in a ring shape, and the surface of the protrusions has a frosted feel. Grinding disk I3 and grinding disk II4 drive the protrusions to rotate towards each other, so that grinding disk I3 and grinding disk II4 crush the sample, and driven by the elastic force of spring 6, the friction with the surface of the protrusions makes grinding disk I3 and grinding disk II4 grind the sample at the same time. At the same time, centrifugal force is generated on the sample during the grinding process, which can avoid the sample being located between the multiple protrusions of grinding disk I3 and grinding disk II4 respectively.

[0024] The inner side of the bottom end of the shell 1 and the outer side of the top end of the grinding disk Ⅰ3 are both provided with steps, and the steps of the shell 1 and the grinding disk Ⅰ3 are connected to each other, so that the sealing between the shell 1 and the grinding disk Ⅰ3 is improved by the steps.

[0025] The inner top thread groove of the base 2 and the outer bottom of the shell 1 are provided with threads, and the shell 1 is threadedly connected to the base 2. The base 2 and the grinding disk I3 can be quickly connected and separated through the threads, making it convenient and quick to clean the samples on the grinding disks I3 and II4.

[0026] Working principle:

[0027] When in use, the spring 6 drives the grinding disk II4 to move downward on the inner side of the shell 1, so that the grinding disk II4 is pressed and contacted with the sample, and by starting the motor I7 and the motor II8, the grinding disk I3 and the grinding disk II4 are rotated toward each other in height. At the same time, the grinding disks I3 and II4 have frosted protrusions on the upper surfaces to grind the sample, and the spring 6 is continuously stretched until the grinding disk II4 is in contact with the grinding disk I3, so that the grinding disk II4 can always be in contact with the sample and maintain effective grinding of the sample, thereby improving the grinding efficiency and grinding quality.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
