Description

Technical Field

[0001] The utility model relates to the technical field of food detection, and more specifically to a device for detecting harmful elements in green food. Background Art

[0002] Green food refers to safe, high-quality edible agricultural products and related products that are produced in a good ecological environment, produced in accordance with green food standards, subject to full quality control and have obtained the right to use the green food logo. Therefore, before green food is sold, it is necessary to use detection equipment to test harmful elements in green food to prevent food that does not meet the requirements from entering the market.

[0003] Based on the above, the inventors found that the existing detection device usually has only one detection end when in use. Therefore, it can only be removed and replaced with a new food sample when the previous food sample completes the detection work. There is a long replacement gap in the middle, which affects the detection efficiency. Therefore, in view of this, the existing structure is studied and improved to provide a green food harmful element detection device, in order to achieve a more practical purpose.

[0026] See also Figure 4 The synchronous adjustment mechanism 7 includes a gear ring 11, a support frame 12 is sleeved on the outer side of the gear ring 11, and one end of the support frame 12 is fixedly connected to a sliding rod 13 and a fixed rod 14 on the upper and lower sides respectively, and a group of second tooth blocks 15 are fixedly connected to the inner sides of the support frame 12 and one side of the gear ring 11. In order to make the sealing cover 5 move synchronously with the replacement of the food sample, a synchronous adjustment mechanism 7 is provided.

[0027] See also Figure 3The support plate 6 is located on the top surface of the base 1, and the base 1 of the support plate 6 is slidably connected in the front-back direction. Two detection grooves are provided on the top surface of the support plate 6, and two food samples can be placed through the two detection grooves.

[0028] See also Figure 3 The two tooth columns 9 are respectively located on the outside of the two groups of first tooth blocks 10, and the tooth columns 9 are meshed and connected with the first tooth blocks 10. When the first sample completes the detection work, the drive motor 4 is started to drive the rotating rod 8 to rotate, and the tooth columns 9 are meshed and connected with the first tooth blocks 10 to make the support plate 6 move to one side, and the sample that has completed the detection leaves the inspection position, and the new sample is replaced, and the second sample is moved toward the bottom of the detection probe 3.

[0029] See also Figure 4 The gear ring 11 is fixedly connected to the middle part of the rotating rod 8, and the second tooth block 15 on one side of the gear ring 11 is meshed with the second tooth block 15 on both sides of the inside of the support frame 12. The rotation of the rotating rod 8 drives the gear ring 11 to rotate synchronously. When the second tooth block 15 on the outside of the gear ring 11 is meshed with the second tooth block 15 on one side of the inside of the support frame 12, the support frame 12 moves outward at this time, driving the sealing cover 5 to separate, so that the first food sample leaves the inspection position. As the gear ring 11 continues to rotate, the second tooth block 15 on the outside of the gear ring 11 is meshed with the second tooth block 15 on the other side of the inside of the support frame 12, driving the sealing cover 5 to reset, and the second food sample moves below the detection probe 3.

[0030] See also Figure 4 The path length of the second tooth block 15 on one side of the tooth ring 11 and the path length of the second tooth block 15 on both sides inside the support frame 12 are both equal to half of the distance between the two detection slots, and the moving path of the support frame 12 is equal to half of the moving path of the inspection sample.

[0031] See also Figure 4 The top end of the sliding rod 13 is slidably connected to the detection bracket 2, and the bottom end of the fixed rod 14 is fixedly connected to the front side of the sealing cover 5. The movement of the support frame 12 drives the support plate 6 to move through the fixed rod 14, and the sliding rod 13 ensures the movement stability of the support frame 12.

At this time, the two sealing covers 5 are arranged in a close fit on the outside of the detection probe 3, so that the detection environment is in a sealed state to avoid interference from external light. When the first sample completes the detection work, the drive motor 4 is started to drive the rotating rod 8 to rotate, and the first tooth block 10 is engaged and connected through the tooth column 9 to move the support plate 6 to one side, and the sample that has completed the detection leaves the inspection position, and a new sample is carried out. During the replacement work, the second sample is moved toward the bottom of the detection probe 3. The rotation of the rotating rod 8 drives the gear ring 11 to rotate synchronously. When the second tooth block 15 on the outer side of the gear ring 11 is meshed and connected with the second tooth block 15 on one side of the inner side of the support frame 12, the support frame 12 moves outward, driving the sealing cover 5 to separate, so as to facilitate the first food sample to leave the inspection position. With the continuous rotation of the gear ring 11, the second tooth block 15 on the outer side of the gear ring 11 is meshed and connected with the second tooth block 15 on the other side of the inner side of the support frame 12, driving the sealing cover 5 to reset. At this time, when the second food sample moves to the bottom of the detection probe 3, the detection of harmful elements can be continued.
