DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 A food inspection homogenizer in this embodiment includes a machine base 1, a machine head 2, a rotating shaft 3 and a stirring and crushing head 4 which together form a machine body structure.

[0031] It should be noted that the machine head 2 is slidably connected to the machine base 1 for up and down adjustment, and cooperates with the machine head 2 to drive the stirring and crushing head 4 integrally connected to the rotating shaft 3 to rotate to crush the sample evenly.

[0034] A driving motor is fixed inside the machine head 2 , and the output shaft of the driving motor is connected and fixed to the rotating shaft 3 via a coupling. The external thread of the machine head 2 is connected to a fastening head in contact with the machine base 1 .

[0035] The driving motor can drive the rotating shaft 3 to rotate when it works.

[0036] In this embodiment, the stirring and crushing head 4 is provided with a telescopic crushing structure, and the rotating shaft 3 is provided with an adjusting sealer.

[0037] It should be noted that the telescopic crushing structure includes a plurality of cutter heads 6 that are movably inserted through the outside of the mixing and crushing head 4, and cooperates with the elastic telescopic parts fixed inside the mixing and crushing head 4 to realize the expansion and folding of the cutter heads 6.

[0038] The elastic telescopic member includes an elastic telescopic rod 5 fixed to the top of the inner cavity of the mixing and crushing head 4, and the other end of the elastic telescopic rod 5 is fixed to a connecting seat 7, and a rotating rod 8 is rotatably connected between the connecting seat 7 and the cutter head 6. The rotating rod 8 rotates up and down, and when the elastic telescopic rod 5 is in a compressed state, the end of the cutter head 6 away from the rotating rod 8 is aligned with the surface of the mixing and crushing head 4.

[0039] The regulating sealer in this embodiment includes an regulating movable member slidably connected to the outside of the rotating shaft 3 , the outside of the regulating movable member is rotatably connected to a rotating seat 12 , and the outer movable sleeve of the rotating seat 12 is provided with an annular sealing airbag 13 .

[0040] The adjusting movable part includes a slide groove 9 opened on the outside of the rotating shaft 3, a ring seat 10 is slidably connected in the slide groove 9, a rotating groove 11 is opened on the outside of the ring seat 10, a rotating seat 12 is located in the rotating groove 11, and an annular sleeve groove for sleeveing ​​an annular sealing airbag 13 is opened on the outside of the rotating seat 12.

[0041] The annular sleeve groove facilitates the installation and replacement of the annular sealing airbag 13.

[0042] When the annular seat 10 is located at the bottom in the slide groove 9, the lower surface of the annular seat 10 is aligned with the lower surface of the stirring and crushing head 4, and the cutter head 6 is aligned with the surface of the stirring and crushing head 4, and the elastic telescopic rod 5 is in a compressed state.

[0043] The upper surface of the cutter head 6 is tilted downward at an angle of thirty degrees from the inside to the outside, so that the annular seat 10 can be moved downward and squeezed to move the cutter head 6 at the same time.

[0044] The outside of the annular sealing airbag 13 is movably connected to a hose 14, the other end of the hose 14 is connected to a rubber inflatable ball 16, and the outside of the rubber inflatable ball 16 is connected to a switch valve.

[0045] A pulley 15 around which the hose 14 passes is fixed to the lower surface of the machine head 2 by means of fastening screws, so as to facilitate the movement and guidance of the hose 14 .

[0046] The switch valve includes an air inlet and outlet cylinder 17 connected to the outside of the rubber inflatable ball 16, a ring seat 18 is fixed inside the air inlet and outlet cylinder 17, an elastic telescopic rod 19 is fixed inside the ring seat 18, and a sealing block 20 is fixed at the other end of the elastic telescopic rod 19 to seal the opening of the ring seat 18.

[0047] When the elastic telescopic rod 19 is in the extended state, the sealing block 20 is separated from the ring seat 18, and the surface thread of the air inlet and outlet cylinder 17 is penetrated by a thread head 21.

[0048] The elastic telescopic rod 1 5 and the elastic telescopic rod 2 19 are both composed of two ends of the telescopic rod fixed to the inner two ends of the telescopic spring.

[0049] The working principle is:

[0050] The sample test tube is clamped and fixed by the provided clamping member 22, and the head portion 2 is moved downward so that the stirring and crushing head 4 is located in the test tube. At the same time, the provided annular seat 10 is slidably connected with the slide groove 9, and the annular seat 10 is moved downward to contact the food in the test tube, and then the provided rubber inflatable ball 16 is manually pressed, so that when the rubber inflatable ball 16 is squeezed, the gas in the rubber inflatable ball 16 is discharged into the annular sealing airbag 13 through the connected hose 14, so that the annular sealing airbag 13 expands and clings to the inner wall of the test tube (it should be noted that when the rubber inflatable ball 16 is squeezed, the sealing block 20 seals the annular seat 18 under the action of air pressure, so that the gas is pressed into the annular sealing airbag 13. When the rubber inflatable ball 16 is released by hand, the internal and external air pressure difference causes the external air pressure to push the sealing block 20 to separate from the annular seat 18, and the elastic telescopic rod 19 is stretched synchronously, and the external The gas in the boundary layer enters into the rubber inflatable ball 16. At the same time, when the gas in the rubber inflatable ball 16 is filled, the elastic telescopic rod 19 is elastically reset to drive the sealing block 20 to move and seal the annular seat 18), thereby facilitating the combination of the rotating shaft 3, the annular seat 10, the rotating seat 12 and the annular sealing airbag 13 to seal the opening of the test tube, thereby facilitating the head 2 to drive the stirring and crushing head 4 on the rotating shaft 3 to rotate in a closed state, while driving the cutter head 6 to rotate synchronously to crush and homogenize the food in the test tube, thereby preventing the food from splashing to the outside of the test tube during the stirring and crushing process, and at the same time facilitating the effective crushing of the food by limiting the crushing space through the sealing member (it should be noted that when the rotating shaft 3 rotates, the rotating seat 12 is connected with the rotating groove 11 by rotation, so that when the rotating shaft 3 drives the annular seat 10 to rotate, it will not synchronously drive the rotating seat 12 to rotate);

[0051] In addition, after the crushing and shaking process, the threaded head 21 is loosened and opened to vent air, so that the annular sealing airbag 13 shrinks and separates from the test tube. The stirring and crushing head 4 is separated from the test tube by moving the machine head 2 upward. At the same time, the lower annular seat 10 moves downward in the slide groove 9, and the annular seat 10 contacts and squeezes the cutter head 6 to move, driving the rotating rod 8 to rotate to press and shrink the elastic telescopic rod 5 until the cutter head 6 is aligned with the surface of the stirring and crushing head 4, so that the annular seat 10 can continue to move down to the bottom wall of the stirring and crushing head 4, thereby facilitating the annular seat 10 to scrape the food on the rotating shaft 3 and the stirring and crushing head 4 into the test tube for storage, thereby avoiding waste (it should be noted that after the movable annular seat 10 is separated from the cutter head 6, the cutter head 6 can be reset and popped out under the elastic reset action of the elastic telescopic rod 5).

[0052] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
