Description

Technical Field

[0001] The invention relates to the technical field of agricultural product sampling devices, in particular to an agricultural product quality detection sampling device which is convenient for random inspection. Background Art

[0002] Agricultural products are items produced in agriculture, such as rice, sorghum, peanuts, corn, wheat and local specialties of various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities, and do not include various processed products. The quality and safety of agricultural products mainly come from primary agricultural products, that is, the reliability, usability and intrinsic value of plants, animals, microorganisms and their products obtained in agricultural activities, including the nutrition, hazards and external characteristic factors formed and remaining in the process of production, storage, circulation and use. There are requirements for characteristics such as grade, specification, quality, as well as requirements for the level of hazards to people and the environment. Therefore, agricultural products often need to undergo special quality testing before entering the market.

[0003] However, the base of agricultural products is large, and comprehensive testing is time-consuming and laborious. Therefore, sampling testing is generally used to conduct quality inspection on the same batch of agricultural products. During the sampling process, a special sampling device is required. Since common agricultural products are mainly particles, common random sampling devices mostly rely on auger blades for transmission. The overall device occupies a large area and is not easy to move. The sampling process is relatively rigid. When dealing with various types of storage containers, the sampling end is not flexible enough, and the device can often only store one sample. When it is necessary to conduct random inspections on a variety of agricultural products, the previously sampled products need to be taken out first, and the operation is relatively cumbersome. To this end, we designed a sampling device for agricultural product quality inspection that is easy to inspect to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a sampling device for detecting agricultural product quality that is convenient for random inspection, and solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sampling device for detecting agricultural product quality that is convenient for random inspection, comprising a shell, a negative pressure fan is fixedly installed inside the shell, and a negative pressure cabin is fixedly mounted on the outside of the shell, the negative pressure cabin and the negative pressure fan are interconnected, and a soft sampling tube is fixedly connected to the outside of the negative pressure cabin, a movable plate is movably mounted on the bottom of the shell, and a cylinder and a guide rail are fixedly installed on the inner side of the shell, a fixed base is fixedly installed above the movable plate, and evenly distributed storage boxes are arranged on the inner side of the fixed base, and the storage boxes and the negative pressure fan match each other.

[0006] Furthermore, a through opening matching the storage box is provided on the top of the shell, and evenly distributed supporting legs are fixedly mounted on the outside of the shell, and a handle is fixedly mounted on the top of the shell.

[0007] Furthermore, a slider is mounted on the outside of the guide rail, the slider is associated with the cylinder, the cylinder and the guide rail are located on both sides of the inner wall of the shell, and the distance between the two sliders matches the length of the storage box.

[0008] Furthermore, an electromagnet and a detector are arranged outside the sliding block, and a metal body matching the electromagnet is arranged outside the storage box.

[0009] Furthermore, the inner fixed sleeve of the shell is provided with an electric telescopic column located below the through opening, the top of the electric telescopic column is provided with a telescopic rod, and the bottom of the storage box is provided with a top groove matching the telescopic rod.

[0010] Furthermore, a storage cabin located on one side of the through opening is fixedly installed on the top of the shell, the inner side of the storage cabin is movably covered with evenly distributed cover plates, the outside of the storage box is provided with a card slot matching the cover plate, and the top of the storage box is provided with a gripping groove.

[0011] Furthermore, a clamping plate is movably mounted on the inner side of the storage cabin, and uniformly distributed clamping springs are fixedly connected between the storage cabin and the clamping plate.

[0012] Furthermore, a limit seat located above the fixed base is fixedly installed inside the shell, a limit plate is movably sleeved below the limit seat, and evenly distributed limit springs are fixedly connected between the limit seat and the limit plate.

[0013] The present invention provides a sampling device for detecting agricultural product quality which is convenient for random inspection and has the following beneficial effects:

[0014] 1. The agricultural product quality inspection sampling device which is convenient for random inspection uses a negative pressure fan and a soft sampling tube as well as a storage box and a shell in coordination. The main body of the agricultural product quality inspection sampling device which is convenient for random inspection is a shell, and a negative pressure fan, a negative pressure cabin, and a soft sampling tube are arranged inside the shell. When the negative pressure fan is working, the negative pressure inside the negative pressure cabin can be changed, thereby causing suction to be generated at the end of the soft sampling tube. When sampling, the staff can directly insert the soft sampling tube into the storage container, and transport the sample to the inside of the shell through the soft sampling tube, the negative pressure cabin, and the negative pressure fan. After entering the shell, the sample can fall into the internal storage of the storage box and wait for output. The volume of the shell and the negative pressure fan is smaller than that of the traditional auger blade, and the movement of the soft sampling tube is also more flexible, so the sampling work can be carried out more conveniently.

[0015] 2. The agricultural product quality inspection sampling device that is convenient for random inspection uses a storage box and a slider as well as an electromagnet and an electric telescopic column, so that during operation, the cylinder of the agricultural product quality inspection sampling device that is convenient for random inspection can be started and the slider can be moved outside the guide rail. When the slider moves to both sides of the storage box, the electromagnet is energized and generates magnetic force, which adsorbs the metal bodies at both ends of the storage box. When the slider continues to move, it can drive the storage box to move until the storage box is moved to match the discharge port of the negative pressure fan. After the negative pressure fan completes sample collection, the electric telescopic column is started and the storage box storing the sample is pushed out of the through opening through the telescopic rod. When sampling different types of agricultural products, the slider drives other storage boxes to store samples, thereby facilitating the sampling device to sample different types of agricultural products.

[0016] 3. The agricultural product quality inspection sampling device that is convenient for random inspection uses a storage box and a cover plate as well as a clamping spring and a clamping plate in coordination, so that after the storage box storing the samples is pushed out, the staff can move the cover plate, take the cover plate out from the inner side of the storage compartment, and insert the cover plate into the inner side of the storage box to seal the samples and prevent the samples from scattering. At the same time, the remaining cover plates are squeezed and fixed again under the action of the clamping plate and the clamping spring, so that the agricultural product quality inspection sampling device that is convenient for random inspection can properly temporarily store the samples.

[0017] 4. The agricultural product quality inspection sampling device that is convenient for random inspection, through the coordinated use of the fixed base and the movable plate as well as the limit spring and the limit plate, enables the storage box to be evenly arranged between the fixed base and the limit plate. The limit plate can squeeze the storage box under the action of the elastic force of the limit spring, and cooperate with the fixed base to assist in fixing the storage box. When it is necessary to add a storage box or to inspect the structure inside the shell, the staff can open the movable plate and drive the fixed base to move to the outside of the shell, thereby facilitating the staff to inspect the inside of the shell or add a storage box.

The principle and use process of the detector 18 are the same as those in the prior art and will not be repeated here.

[0029] See also Figure 1 and Figure 3 as well as Figure 4 A fixed base 12 is fixedly installed above the movable plate 13, and evenly distributed storage boxes 10 are arranged on the inner side of the fixed base 12. The storage boxes 10 and the negative pressure fan 9 match each other. A through opening 4 matching the storage box 10 is opened on the top of the shell 1. The storage box 10 is used to store samples extracted by the negative pressure fan 9. After storage, the storage box 10 needs to be taken out from the inside of the shell 1, and the through opening 4 is used for the output of the storage box 10. Evenly distributed supporting legs 14 are fixedly installed on the outside of the shell 1, and a handle 2 is fixedly installed on the top of the shell 1. When the device as a whole is in use, the staff can hold the handle 2 to move the shell 1 as a whole. After the shell 1 is moved to the specified position, it can be supported by the supporting legs 14.

[0030] The shell 1 is internally fixed with an electric telescopic column 11 located below the through opening 4. After the sample enters the storage box 10 for internal storage, the electric telescopic column 11 can be started and the telescopic rod 19 can be extended. The top of the electric telescopic column 11 is provided with the telescopic rod 19. The bottom of the storage box 10 is provided with a top groove matching the telescopic rod 19. The top end of the telescopic rod 19 can contact with the top groove at the bottom of the storage box 10, and then the storage box 10 storing the sample is ejected from the shell 1 through the through opening 4.

[0031] See also Figures 5 to 7A storage compartment 6 located on one side of the through opening 4 is fixedly installed above the shell 1, and a cover plate 5 evenly distributed is movably mounted on the inner side of the storage compartment 6. A card slot matching the cover plate 5 is provided on the outside of the storage box 10.

The cylinder 15 works and drives the slider 20 to move outside the guide rail 16. When the slider 20 moves to both sides of the storage box 10, the detector 18 detects the presence of the storage box 10 and controls the slider 20 to power the electromagnet 17. After the electromagnet 17 is energized, it generates magnetic force and interacts with the metal bodies at both ends of the storage box 10. 25 are attracted to each other, the slider 20 continues to move and drives the storage box 10 to move until the storage box 10 is moved to match the discharge port of the negative pressure fan 9. After the negative pressure fan 9 is started, the negative pressure inside the negative pressure cabin 8 is changed, and then the end of the soft sampling tube 7 generates suction, and the sample is transported to the inside of the shell 1 through the soft sampling tube 7, the negative pressure cabin 8, and the negative pressure fan 9. After entering the shell 1, the sample falls into the storage box 10 for internal storage and waits for output. At this time, the electric telescopic column 11 is started and the telescopic rod 19 is extended. The telescopic rod 19 and the storage box 10 The bottoms are in contact with each other, and then the storage box 10 storing the sample is pushed out from the shell 1 through the through opening 4. After the storage box 10 is pushed out, the cover plate 5 is moved, the cover plate 5 is taken out from the inner side of the storage cabin 6, and the cover plate 5 is inserted into the inner side of the storage box 10 to seal the sample to prevent the sample from scattering. At the same time, the remaining cover plates 5 are squeezed and fixed again under the action of the clamping plate 23 and the clamping spring 24. When sampling different types of agricultural products, each mechanism is started again and the above operation is circulated. When the storage box 10 needs to be added, the movable plate 13 is opened. The fixed base 12 is driven to move to the outside of the shell 1, and the storage box 10 is filled into the interior of the fixed base 12. When the movable plate 13 is closed, the top of the storage box 10 contacts the limit plate 22 and pushes the limit plate 22 to move inside the limit seat 3, while compressing the limit spring 21. When the movable plate 13 is closed and stable, the limit plate 22 squeezes the storage box 10 under the action of the limit spring 21, and cooperates with the fixed base 12 to assist in fixing the storage box 10, thereby completing the entire use process of the agricultural product quality detection sampling device that is convenient for random inspection.
