Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a decomposition device for food detection. Background Art

[0002] By testing food ingredients, additives, pesticide residues, total bacteria count and other indicators, the quality and safety of food can be effectively judged, thereby protecting the rights and interests of consumers. In the process of food safety testing, different foods are usually handled differently during the testing process. When handling some harder foods during the testing process, they usually need to be crushed by decomposition equipment first. Existing decomposition processing equipment includes grinding and crushing decomposition and crushing knife crushing and decomposition. When the crushing knife is used to crush harder foods, since the food is harder, the crushing knife is often damaged during the crushing process, which will lead to broken knife chips in the crushed food. Since there is no knife chip separation mechanism in the decomposition equipment, the subsequent testing of the decomposed food sample mixed with knife chips will have a certain impact on the test results. Therefore, a decomposition device for food testing is proposed to address the above problems. Utility Model Content

[0023] Example 2

[0024] like Figure 1-2 As shown, in order to solve the problem of poor sealing between the bucket cover 1 and the crushing barrel 2, a sealing ring 4 is fixedly connected to the top of the crushing barrel 2, and the sealing ring 4 is in close contact with the bucket cover 1. The sealing ring 4 is made of rubber. By arranging the sealing ring 4 made of rubber between the bucket cover 1 and the crushing barrel 2, the sealing between the bucket cover 1 and the crushing barrel 2 is improved.

[0025] Example 3

[0026] like Figure 2 As shown, in order to solve the problem of inconvenience in controlling the rotation of the crushing knife 10, a motor 7 is fixedly connected to the right end of the inner side of the barrel cover 1, and the end of the main shaft of the motor 7 is fixedly connected to a driving bevel gear 8. The outer side of the driving bevel gear 8 is meshed with a driven bevel gear 9, and the driven bevel gear 9 at the top is fixedly connected to the fixed shaft 5, and the driven bevel gear 9 at the bottom is fixedly connected to the sleeve shaft 6. The driving bevel gear 8 is driven by the motor 7 to mesh with the driven bevel gear 9, which facilitates the control of the rotation of the crushing knife 10.

[0027] Example 4

[0028] like Figure 2 As shown, in order to solve the problem of being inconvenient to quickly position the iron plate 11 after being pressed down, the block 15 is slidably connected to the crushing barrel 2, and the block 15 is engaged with the iron plate 11. The top side of the block 15 is tilted. By making the top of the block 15 tilted, when the iron plate 11 is pressed and the inclined surface of the block 15 comes into contact, it is convenient to automatically control the block 15 to compress the second spring 16 and retract it into the inner wall of the crushing barrel 2.

[0029] Example 5

[0030] like Figure 2-4 As shown, in order to solve the problem of inconvenience in replacing the damaged crushing knife 10, a fixing sleeve 17 is provided at one end of the outer side of the fixed shaft 5 and one end of the outer side of the sleeve shaft 6. A slider 18 is rotatably connected to the inner side of the fixing sleeve 17. A fixing block 19 is fixedly connected to one end of the outer side of the slider 18, and the fixing block 19 is slidably connected to the fixing sleeve 17. A positioning shaft 20 is fixedly connected to the bottom end of the fixing block 19.

The fixing block 19 at the bottom and the positioning shaft 20 at the bottom are both slidably connected to the fixed shaft 5. The outer side of the positioning shaft 20 is slidably connected to a connecting block 21. The connecting block 21 at the top is slidably connected to the sleeve shaft 6, and the connecting block 21 at the bottom is slidably connected to the fixed shaft 5.

By rotating the fixing sleeve 17 and the spiral connection with the fixed shaft 5 or the sleeve shaft 6, the fixing block 19 is further driven upward by the slider 18, thereby controlling the positioning shaft 20 to slide upward from the connecting block 21 outside the crushing knife 10, which facilitates the removal of the damaged crushing knife 10 for replacement.

[0031] In this embodiment, when the device is used to decompose harder food before testing, the magnetic plate 12 is first sucked onto the iron plate 11, and then the magnetic plate 12 is pressed to compress the first spring 13. When the iron plate 11 contacts the bottom end of the inner side of the crushing barrel 2 and the clamping block 15 is clamped together with the iron plate 11 under the elastic force of the second spring 16, the food can be crushed during decomposition. At this time, the food is placed in the crushing barrel 2, and the barrel cover 1 is rotated to be spirally connected to the crushing barrel 2. Then, the controller 3 controls the motor 7 to drive the active bevel gear 8 to engage the driven bevel gear 9, further controls the fixed shaft 5 to rotate, and at the same time controls the sleeve shaft 6 to rotate with the fixed shaft 5. Rotation in opposite directions can control the rotation of the upper and lower crushing blades 10 to crush the food. After the food is crushed, when the crushing blade 10 is damaged, the magnetic plate 12 will adsorb the crushing blade 10 debris in the crushed food, so that when the crushed food is poured out for testing, it can prevent the knife chips from mixing in the crushed food and affecting the subsequent test results. Then, by rotating the fixed sleeve 17 and spirally connecting it with the fixed shaft 5 or the sleeve shaft 6, the fixed block 19 is further driven upward by the slider 18, thereby controlling the positioning shaft 20 to slide upward from the connecting block 21 on the outside of the crushing blade 10, and the damaged crushing blade 10 can be removed for replacement.
