Description

Technical Field

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

[0002] In order to ensure the safety of food, food must be tested. Food testing uses the sampling rules in statistics to first sample samples from many foods, that is, samples, and then test the samples to determine the safety of food samples based on certain rules and standards.

[0003] In the prior art, when sampling food, such as sampling grain in a granary, a sampling rod is generally inserted into the piled grain, and then a plurality of sampling holes are opened on the surface of the sampling rod. After the sampling rod is inserted into the grain, the sampling holes are opened, so that grains at different depths can be sampled. However, such sampling devices in the prior art are more cumbersome to operate, and an additional step of opening the sampling holes is required. Therefore, an improved sampling device for food testing is needed to address this problem. Utility Model Content

[0020] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] See also Figure 1-5 The utility model provides a technical solution: a sample sampling device for food detection, comprising a sampling rod 1, wherein a plurality of sampling mechanisms are arranged at the lower end of the sampling rod 1, wherein the sampling mechanisms include storage bins 2, filling blocks 3, cavities 4, and movable cover plates 5, wherein a plurality of storage bins 2 are evenly and fixedly arranged inside the lower end of the sampling rod 1, a filling block 3 is fixedly arranged at the lower end of the storage bin 2, a cavity 4 is arranged on one side of the filling block 3, and a movable cover plate 5 is movably engaged inside the cavity 4 so that the movable cover plate 5 can move up and down inside the cavity 4.

[0022] A spring 6 is provided at the lower end of the movable cover plate 5 inside the cavity 4, and the movable cover plate 5 can be pushed upward by the spring 6, that is, the spring 6 is always kept in a compressed state;

[0023] A handle 7 is fixedly provided on the upper end of the sampling rod 1, and the device can be conveniently held by the handle 7, so that the device can be conveniently inserted into the grain pile;

[0024] A guide block 8 is fixedly provided at the lower end of the sampling rod 1, and the guide block 8 can act as a drill bit, and can also facilitate the insertion of the sampling rod 1 into the grain pile;

[0025] The outer surface of the upper end of the sampling rod 1 is provided with a scale 9, through which the operator can understand the insertion depth of the device conveniently;

[0026] The outer surface of the movable cover 5 is provided with a groove 10, and the friction between the rice and the movable cover 5 can be increased through the groove 10. When the sampling rod 1 is inserted into the rice pile, the friction force on the movable cover 5 is upward, and the friction force affects the elastic force of the spring 6 to keep the movable cover 5 closed; and when the sampling rod 1 is fully inserted into the rice pile, when the sampling rod 1 is pulled out, the movable cover 5 is subjected to a downward friction force, and as the sampling rod 1 is pulled out, the movable cover 5 compresses the spring 6 and moves downward, forming a Figure 5In the state shown, as the sampling rod 1 moves upward, the rice in the grain pile can enter the cavity 4, so that the stratified sampling can be completed; until the movable cover 5 is pulled out of the grain pile; the elastic force of the spring 6 can push the movable cover 5 to close, and then when the staff wants to take out the rice stored in the cavity 4, the groove 10 makes it convenient for the staff to push the movable cover 5 down; thereby, the cavity 4 is opened, which can facilitate the workers to pour out the rice.

[0027] Working principle: When the device is used for sampling, the sampling rod 1 is directly inserted into the grain pile. When the sampling rod 1 is inserted into the grain pile, the movable cover 5 moves downward and the friction force is opposite to the moving direction of the movable cover 5. In this way, the friction force on the movable cover 5 is upward. At this time, the movable cover 5 is affected by the friction force and the elastic force of the spring 6 to keep the movable cover 5 closed. When the sampling rod 1 is fully inserted into the grain pile, the sampling rod 1 is pulled out. At this time, the movable cover 5 is subjected to a downward friction force. This friction force can overcome the elastic force of the spring 6. As the sampling rod 1 is pulled out, the movable cover 5 compresses the spring 6 and moves downward, forming a Figure 5 In the state shown, as the sampling rod 1 moves upward, the rice in the grain pile can enter the cavity 4, so that the stratified sampling can be completed; until the movable cover 5 is pulled out from the grain pile; the movable cover 5 can be pushed closed under the elastic force of the spring 6 (there may be a certain amount of rice stuck in the closed part of the movable cover 5, but after the sampling rod 1 is pulled out, the staff will need to check the dryness of the taken out rice, and whether the movable cover 5 is airtight has little effect), and then when the staff wants to take out the rice stored in the cavity 4, the groove 10 facilitates the staff to push the movable cover 5 down; thereby, the cavity 4 is opened, and it is convenient for the workers to pour out the rice to check the dryness. In this way, when the device is used for sampling, it only needs to be plugged and unplugged once, which can improve the sampling efficiency and is easy to operate. Compared with the sampling device in the traditional technology, it is more convenient to promote and use.
