Description

Technical Field

[0001] The present invention relates to the technical field of pesticide residue detection, and particularly to a portable pesticide residue detection device. Background Art

[0002] Pesticide residue detection is an important link to ensure food safety, promote the sustainable development of agriculture and safeguard public health. Excessive residues of some highly toxic pesticides (such as organophosphorus) may cause vomiting, convulsions and even death, posing a greater threat to sensitive populations such as children and pregnant women. Long-term exposure to low-dose pesticide residues may be associated with cancers, neurodegenerative diseases (such as Parkinson's disease), reproductive disorders, etc. In addition, excessive pesticides can cause land pollution, and then pollute the environment, resulting in incalculable consequences.

[0003] Therefore, pesticide residue detection is not only a legal obligation, but also a means of risk control throughout the entire chain from farmland to table. With the upgrading of consumers' health demands and the strengthening of global green trade rules, pesticide residue detection is transforming from a "compliance cost" to a "competitive strategic asset".

[0004] Traditional pesticide residue detection devices are relatively large in size. It is necessary to manually collect relevant products and transport them to the detection room for processing the products to be detected using relevant equipment. The entire process is relatively long, which is not conducive to quickly obtaining the pesticide residue detection results.

[0005] Therefore, in order to further facilitate the timely detection of pesticide residues, a portable pesticide residue detection device is specifically proposed, which can be placed in a vehicle and can directly and quickly detect the extracted products at the product location. Summary of the Invention

[0006] To solve the technical problems proposed in the background art, the present invention provides a portable pesticide residue detection device.

[0007] The present invention is implemented by the following technical solutions: A portable pesticide residue detection device includes a device body, a crushing member, a shaking member and a detection member.

[0008] The device body is successively connected by a lower housing, an upper housing and a feeding port from bottom to top. The three are communicated, and one side of the lower housing is provided with an opening.

[0009] The crushing member is arranged in the upper housing and is used for crushing the product to be detected and pushing the crushed tissue into the lower housing for collection.

[0010] The shaking member is arranged at the lower housing and is connected to the crushing member. When the crushing member moves vertically back and forth, it synchronously shakes and homogenizes the tissue and then stands still after shaking and homogenizing.

[0011] The detection component is installed inside the lower housing and is used to detect the tissue after standing still. Specifically, the detection component can be realized by a rapid detection card / test strip, an integrated optical spectrum or an electrochemical sensor and ultraviolet detection (not shown).

[0012] As a further improvement of the above solution, the crushing component includes a crushing assembly, an upper scraping component, a lower cleaning component and a driving component. The crushing assembly, the upper scraping component and the lower cleaning component are arranged inside the upper housing, and the driving component is arranged at the top of the upper housing.

The outer walls of the two frustum-shaped bodies are evenly fixedly connected with convex blocks, and the convex blocks at the positions where the two frustum-shaped bodies are close to each other are engaged. The outer walls of the two convex blocks are spirally provided with groove openings. Specifically, the groove openings are spiral and continuous tooth openings provided on the outer wall of the convex blocks, which are used to further improve the contact with the crushed product and improve the crushing efficiency and effect. The bottom ends of the two frustum-shaped bodies are respectively coaxially and rotatably connected with a cylinder and a sliding rod. The cylinder is fixedly connected to the bottom end of the upper housing, and the sliding rod is vertically slidably connected to the bottom end of the upper housing. A blanking opening is provided in the middle of the bottom end of the upper housing, and the blanking opening is directly below the connection position of the two frustum-shaped bodies. Chamfers are provided on the outer walls of the top ends of the two frustum-shaped bodies to facilitate guiding the product to be crushed under the engagement and extrusion of the convex blocks.

[0014] As a further improvement of the above solution, the upper scraping component includes two sliding sleeve blocks respectively slidably connected to the outer walls of the rotating shafts. The two sliding sleeve blocks are movable on the upper ends of the frustum-shaped bodies. The same sides of the two sliding sleeve blocks are fixedly connected with guiding plates. Arc-shaped guiding groove openings are provided on the inner sides of the two guiding plates along the rotating direction of the frustum-shaped bodies, which are used to receive and guide the product to the engagement position of the two convex blocks for crushing. A connecting plate is fixedly connected in the middle of the two guiding plates. A convex plate is fixedly connected to the middle of one side of the connecting plate. A spring is connected between the convex plate and the middle of the top end of the upper housing. The spring is used to ensure that the guiding plate always abuts against the top end of the frustum-shaped body and guide and position the product for crushing.

[0015] As a further improvement of the above solution, the lower cleaning component includes fixing rings respectively fixedly connected to the outer walls of the bottom ends of the two frustum-shaped bodies. Cleaning plates are fixedly connected to the outer walls of the two fixing rings. The cleaning plates are provided with an upward slope along the rotating direction of the frustum-shaped bodies, which is used to clean the tissue at the bottom end of the upper housing to the blanking opening when the cleaning plates rotate.

[0016] As a further improvement of the above solution, the driving component includes a driving rod rotatably connected to the middle of one side of the top end of the upper housing. The driving rod is L-shaped. A rotating handle is fixedly connected to the outer side of the driving rod, and a second bevel gear is fixedly connected to the inner side of the driving rod. Vertical grooves are symmetrically formed in the outer wall of the rotating shaft near the second bevel gear, and a spiral displacement notch is formed in the outer wall of the rotating shaft outside the upper housing.

[0043] The upper scraping assembly includes two sliding sleeve blocks 15 respectively slidably connected to the outer walls of the rotating shafts 4. The two sliding sleeve blocks 15 move on the upper ends of the frustums 5. The same sides of the two sliding sleeve blocks 15 are fixedly connected with guiding plates 16.

[0044] The lower cleaning assembly includes fixing rings 30 respectively fixedly connected to the outer walls of the bottoms of the two frustums 5. Cleaning plates 31 are fixedly connected to the outer walls of the two fixing rings 30.

[0045] The driving assembly includes a driving rod 11 rotatably connected to the middle of one side of the top of the upper housing 1. The driving rod 11 is L-shaped. A handle 12 is fixedly connected to the outer side of the driving rod 11, and a second bevel gear 10 is fixedly connected to the inner side of the driving rod 11. Vertical grooves are symmetrically formed on the outer wall of the rotating shaft 4 near the second bevel gear 10, and a spiral displacement notch 28 is formed on the outer wall of the rotating shaft 4 outside the upper housing 1.

A connecting rod 14 is fixedly connected to one side of each of the two rotating sleeve blocks 13. When the rotating shaft 4 driven by the displacement notch 28 rotates and moves vertically reciprocally synchronously, under the connection of the rotating sleeve block 13 and the connecting rod 14, the other rotating shaft 4 moves synchronously.

[0046] The implementation principle of a portable agricultural residue detection device in the embodiment of the present application is as follows:

[0047] When agricultural residue detection of a product is required, take out the accompanying device and place it on a flat area. After installing the static box 26, place the product at the feeding port 3 according to its size and press it down. Larger-sized products need to be cut. Then, directly rotate the handle 12 clockwise in the established direction with one hand. Under the meshing connection of the second bevel gear 10 and the first bevel gear 8, the rotating shaft 4 drives the entire table body 5 to rotate, and the convex block 6 drives the other table body 5 to rotate. The two table bodies 5 perform extrusion and crushing on the pressed product. As the two table bodies 5 rotate, the contact surface with the product can be further improved by using the groove opening 7. One of the rotating shafts 4 can achieve reciprocating rotation in the vertical direction by the sliding connection between the displacement notch 28 and the spherical block 29. Under the connection of the rotating sleeve block 13 and the connecting rod 14, the other rotating shaft 4 is synchronously driven to perform reciprocating displacement in the vertical direction. As the crushing progresses, the product tissue will fall to the bottom end of the inner wall of the upper housing 1.

[0048] At the same time, the guiding plate 16 at the top will remain in contact with the top of the table body 5 under the elasticity of the spring 18, so that the rotating table body 5 can be guided by the guiding plate 16 to guide the product to the two table bodies 5, facilitating the crushing operation. As the two table bodies 5 reciprocate in the vertical direction, the contact with the product can be further improved.

[0049] Meanwhile, the cleaning plate 31 at the bottom will rotate with the rotation of the table body 5, and under the vertical reciprocating displacement, it will clean the tissues accumulated and precipitated on the inner wall of the bottom end of the upper shell 1, and make them fall into the lower shell 2 for collection. A plug plate can also be slidably connected to the bottom end of the feeding port 27, and a sealing rubber ring is provided at the connection between the plug plate and the bottom end of the upper shell 1 to artificially control the crushing time by using the plug plate.

[0050] Embodiment 2: Combining Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 , on the basis of Embodiment 1, the further improvement of this embodiment lies in:

[0051] The oscillating member includes guiding strips 23 symmetrically and fixedly connected to both sides of the inner wall of the upper shell 1. A sliding plate 24 is horizontally slidably connected to the two guiding strips 23. A placement slot is provided at the middle of the sliding plate 24 facing the opening of the lower shell 2. Insertion slots 25 are symmetrically opened on both sides of the sliding plate 24 where the placement slot is located. A static box 26 is inserted and connected in the insertion slots 25. The top port diameter of the static box 26 is larger than the diameter of the feeding port 27. One side of the top end of the sliding plate 24 is fixedly connected with a guiding frame plate 22. The top end of the guiding frame plate 22 is an inclined guiding slot. A slider 21 is slidably connected to the guiding slot. The slider 21 is fixedly connected to one side of the sliding rod 20. When the rotating shaft 4 drives the sliding rod 20 to slide vertically in a reciprocating manner, the entire sliding plate 24 is driven to drive the static box to slide horizontally in a reciprocating manner along the guiding strips 23, cooperate with pouring an appropriate amount of pure water from the feeding port 3 for oscillating treatment, and after the crushing operation is completed, perform static settling. After the static settling is completed, the detection member detects the static product mixture.

[0052] The implementation principle of a portable agricultural residue detection device in the embodiment of the present application is as follows:

[0053] As the two table bodies 5 slide vertically in a reciprocating manner, one of the table bodies 5 will drive the sliding rod 20 at the bottom to slide vertically in a reciprocating manner synchronously. Under the oblique sliding of the slider 21 and the guiding frame plate 22, the entire sliding plate 24 slides horizontally in a reciprocating manner along the guiding strips 23, so that the static box 26 inserted at the insertion slots 25 oscillates the tissues placed inside, accelerates the internal homogenization, and appropriately adds pure water at the feeding port 3 to accelerate the mixing of the two. After the crushing is completed, wait for the precipitation to complete, and cooperate with the detection member for quick detection.

[0054] The above implementation manners are only the preferred implementation manners of the present invention and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
