[0021] The following provides a detailed description of two implementation manners of the present application with reference to the accompanying drawings.

[0022] The first implementation manner:

[0023] Figures 1-4 There is shown a sample crushing device for food detection, including a base 1. A pair of fixed frames 2 are fixedly connected to the upper end of the base 1. A cylinder 3 is fixedly connected to the inner wall of the fixed frame 2. A threaded plate 4 is threadedly connected to the inner wall of the cylinder 3. A pair of circular grooves are opened at the upper end of the base 1. An electric push rod 1 5 is fixedly connected inside the circular grooves. Those skilled in the art can make an optimal selection of the model of the electric push rod 1 5, such as ETS-50. A circular plate 1 6 is fixedly connected to the telescopic end of the electric push rod 1 5. A circular plate 2 7 is placed in a fitting manner on the upper end of the circular plate 1 6. An adjusting motor 9 is fixedly connected to the upper end of the circular plate 2 7. Those skilled in the art can make an optimal selection of the model of the adjusting motor 9, such as model Y80M1-2. An insertion connecting pipe 10 is fixedly connected to the output end of the adjusting motor 9. A material receiving cylinder 11 and a filter plate 1 12 are slidably sleeved on the outer end of the insertion connecting pipe 10. A plurality of crushing knives 25 are fixedly connected to the outer end of the insertion connecting pipe 10. A limit ring 13 is movably sleeved on the outer end of the filter plate 1 12. A plugging groove is opened at the lower end of the limit ring 13. The upper end of the material receiving cylinder 11 is movably inserted into the plugging groove. A pair of electric push rods 2 14 are fixedly connected to the upper end of the fixed frame 2. Those skilled in the art can make an optimal selection of the model of the electric push rod 2 14, such as ETS-30. A water tank 15 is fixedly connected to the telescopic end of the electric push rod 2 14. A water pump is fixedly connected inside the water tank 15. A water pipe 16 is fixedly connected to the water outlet end of the water pump. A sprayer 17 is fixedly connected to the lower end of the water pipe 16;

[0024] A pair of fixed pipes 8 are fixedly connected to the upper end of the circular plate one 6. A pair of fixed slots into which the fixed pipes 8 are movably inserted are provided at the lower end of the circular plate two 7. The lower end of the material receiving cylinder 11 is fixedly connected to the upper end of the circular plate two 7. The outer diameter of the filter plate one 12 is smaller than the inner diameter of the limiting ring 13. The material receiving cylinder 11, the filter plate one 12 and the limiting ring 13 are fixedly connected by bolts. A water inlet pipe is fixedly connected to the upper end of the water tank 15. A pair of limiting pipes 18 are fixedly connected to the upper end of the limiting ring 13. A pair of docking slots into which the limiting pipes 18 are movably inserted are provided at the lower end of the cylinder 3. A push rod 20 is fixedly connected to the upper end of the threaded plate 4. A feed inlet 21 is provided at the upper end of the threaded plate 4. A sealing plug 22 is movably inserted into the interior of the feed inlet 21.

[0025] Before crushing the sample, place the circular plate two 7 on the circular plate one 6. At this time, the fixed pipes 8 will be inserted into the fixed slots, so that the circular plate two 7 is not easy to rotate on the circular plate one 6, improving the stability of the circular plate two 7. Then insert the lower end of the filter plate one 12 into the limiting ring 13, and then sleeved the limiting ring 13 on the material receiving cylinder 11. Use bolts to fix the material receiving cylinder 11, the filter plate one 12 and the limiting ring 13 into a whole. Then start the electric push rod one 5 to push the circular plate one 6 and the filter plate one 12 upward until the filter plate one 12 is inserted into the cylinder 3 (as shown in combination with Figure 3 ), at the same time, the upper part of the insertion pipe 10 and the crushing knife 25 will be inserted into the cylinder 3, and the limiting pipe 18 will be inserted into the docking slot. The limiting pipe 18 can limit the filter plate one 12 so that it is not easy to rotate together with the insertion pipe 10, thus completing the installation work before crushing the sample;

[0026] When crushing the sample, place the sample in the cylinder 3. Start the adjustment motor 9 to drive the insertion pipe 10 and the crushing knife 25 to rotate in the cylinder 3 by its output end (at this time, the outer end of the insertion pipe 10 also rotates in the filter plate one 12 and the material receiving cylinder 11), and cut the sample in the cylinder 3 through the crushing knife 25. After the sample is crushed into the required size, it will pass through the filter plate one 12 and fall into the material receiving cylinder 11, which is convenient for personnel to collect the crushed sample. Then start the electric push rod one 5 to pull the circular plate one 6 and the filter plate one 12 downward until the insertion pipe 10 and the crushing knife 25 are removed from the cylinder 3. Finally, remove the circular plate two 7 from the circular plate one 6, and then remove the bolts from the limiting ring 13, and then remove the limiting ring 13 from the filter plate one 12. After removal, there is a gap between the filter plate one 12 and the material receiving cylinder 11, so pour out the crushed sample in the material receiving cylinder 11 for detection;

[0027] After the sample is broken, when cleaning the sample debris on the inner wall of the cylinder 3 and cleaning the inner wall of the cylinder 3, manually rotate the push rod 20 to drive the threaded plate 4 to rotate in the cylinder 3 and move downward along the inner wall of the cylinder 3. During the movement, it will push the sample debris adhering to the inner wall of the cylinder 3, so as to take out the debris adhering to the inner wall of the cylinder 3. Its cleaning steps are simple and time-saving, greatly improving the convenience of personnel cleaning debris and the efficiency of breaking samples. After taking out the threaded plate 4 and the push rod 20 from the cylinder 3, start the second electric push rod 14 to make its telescopic end pull the water tank 15 and the nozzle 17 downward. When the nozzle 17 enters the cylinder 3 (combined with Figure 4 as shown), start the water pump to spray the water in the water tank 15 onto the inner wall of the cylinder 3 through the nozzle 17. As the nozzle 17 continuously moves downward in the cylinder 3, the water can be sprayed on different positions in the cylinder 3, so as to facilitate the personnel to clean the inner wall of the cylinder 3, make it not easy for the sample debris to adhere to the inner wall of the cylinder 3, and then make it not easy for different sample debris to be mixed together, and then ensure the accuracy of the sample detection result. And the cleaning steps are simple and convenient for personnel to operate.

[0028] The second implementation mode:

[0029] On the basis of the first implementation mode, this implementation mode adds structures such as the water box 24, and the rest is the same as the first implementation mode.

[0030] Figures 4-5 It is shown that the side end of the fixed frame 2 is fixedly connected with the third electric push rod 23. Those skilled in the art can make the best choice for the model of the third electric push rod 23, such as ETS-50. The telescopic end of the third electric push rod 23 is fixedly connected with the water box 24, and the filter plate two 19 is movably inserted inside the water box 24.

[0031] When cleaning the inner wall of the cylinder 3 and cleaning the debris in the cylinder 3, it is necessary to start the third electric push rod 23 to make its telescopic end push the water box 24 to move directly below the cylinder 3. At this time, the water box 24 will be directly above the insertion pipe 10 (combined with Figure 4 as shown), and the water box 24 does not contact the insertion pipe 10, so that the debris pushed out from the cylinder 3 will fall on the filter plate two 19 in the water box 24, and the inner diameter of the cylinder 3 is smaller than the inner diameter of the water box 24, so that the debris is not easy to fall outside the water box 24 when falling, which is convenient for personnel to collect the sample debris. At the same time, the water for cleaning the inner wall of the cylinder 3 will also enter the water box 24, and the filter plate two 19 can filter the debris contained in the water. On the one hand, it can reduce the waste of debris, and on the other hand, it can improve the cleanliness of the water so that it can be recycled.

[0032] Combined with the current actual requirements, the above-described embodiments adopted in this application, the scope of protection is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the scope of protection of this utility model.
