Description

Technical Field

[0001] This utility model belongs to the field of agricultural product testing technology, and in particular to a device for detecting pesticide residues in agricultural products. Background Technology

[0002] The development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. Strict limits exist for pesticide residues in agricultural products, and accurate detection of pesticide residues in crops is necessary to ensure compliance. This requires the use of detection devices, which first pulverize the agricultural products. However, pulverization can result in dead zones, affecting the uniformity of the pulverization process.

[0003] A search revealed a Chinese patent document (authorization announcement number CN118329574B) for a pesticide residue detection device for agricultural products. The device includes a detection platform with a crushing component, a mixing component, a detector, and a test tube tray on its top. Several test tubes are inserted into the top of the test tube tray. The crushing component includes a horizontally fixed crushing tank with openings at both ends. An inner circular plate is horizontally slidably sealed inside the crushing tank, and an outer circular plate, coaxially arranged with the crushing tank, moves horizontally to its side. The diameter of the outer circular plate is larger than the inner diameter of the crushing tank. The inner and outer circular plates also move synchronously. An addition tube communicating with the inner cavity of the crushing tank is fixedly installed on its upper outer wall. This invention solves the problems of poor crushing effect on crops and the inability to uniformly mix the crushed crops with the pesticide residue detection buffer solution, leading to low accuracy of detection results; and the problem of cross-contamination during continuous testing of crops. The aforementioned patent's detection device requires prior crushing of agricultural products, but the crushing process has dead zones, affecting the uniformity of crushing. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide residue detection device for agricultural products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pesticide residue detection device for agricultural products, comprising a detector for detecting pesticide residues in agricultural products and a crushing bucket for crushing agricultural products. The detector is installed on the top of a counterweight plate, and an inverted U-shaped assembly plate is welded to the top of the counterweight plate. An assembly ring plate is provided between the assembly plate and the counterweight plate, and arc-shaped plates are welded to both sides of the assembly ring plate.

[0006] The arc-shaped plate is rotatably connected to the assembly plate via the first rotating shaft. A servo motor that provides power to the first rotating shaft is installed on the outer wall of the assembly plate. A rotary motor is installed on the outer wall of the assembly ring plate. The output shaft of the rotary motor passes through the assembly ring plate and the crushing barrel and is connected to a rotating rod. Multiple movable crushing blades are welded to the outer periphery of the rotating rod.

[0007] As a preferred embodiment, the outer periphery of the crushing barrel is also connected to multiple feed pipes that penetrate the assembly ring plate, and the outer periphery of the crushing barrel is connected to a feed pipe with a threaded cap.

[0008] As a preferred embodiment, a control valve is installed on the outer periphery of the feed pipe.

[0009] As a preferred embodiment, pulleys for limiting the assembly ring plate are installed on the top of the counterweight plate and on the transverse inner wall of the assembly plate.

[0010] As a preferred embodiment, the inner wall of the grinding barrel is welded with multiple fixed grinding blades that are adapted to the movable grinding blades, and the outer periphery of the rotating rod is also welded with multiple stirring blades for stirring agricultural products, and the stirring blades do not contact the fixed grinding blades.

[0011] As a preferred embodiment, a viewing window is embedded in the outer periphery of the crushing barrel.

[0012] As a preferred embodiment, a test tube box is also installed at the top of the counterweight plate, and the test tube box contains multiple test tubes for liquid sampling and testing.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This pesticide residue detection device for agricultural products benefits from the design of a servo motor and an assembly ring plate. The servo motor drives the first rotating shaft and the arc plate to rotate, which in turn causes the assembly ring plate and the crushing barrel to deflect at a certain angle, thereby changing the tilt angle of the crushing barrel. Compared with the horizontal design of the crushing barrel, this avoids dead corners in the crushing process, ensures the uniformity of crushing, and indirectly improves the accuracy of pesticide residue detection in agricultural products. During rotation, the pulley can limit the assembly ring plate to ensure its stability.

[0015] This pesticide residue detection device for agricultural products benefits from the design of a rotary motor, a movable pulverizing blade, and a fixed pulverizing blade. The rotary motor drives the rotating rod to rotate, which in turn drives the movable pulverizing blade to rotate. This allows the movable pulverizing blade to work in conjunction with the fixed pulverizing blade to pulverize the agricultural products in the pulverizing barrel. The rotation of the stirring blade can agitate the existing agricultural products, change their state, and improve the pulverizing effect.

[0016] This pesticide residue detection device for agricultural products can not only pulverize agricultural products, but also adjust the process to avoid dead zones in the pulverization and ensure uniform pulverization. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] Please see Figures 1 to 4As shown, an agricultural product pesticide residue detection device is provided. This embodiment includes a detector 1 for detecting pesticide residues in agricultural products and a pulverizing bin 2 for pulverizing agricultural products. The detector 1 can be a fully automatic 24-channel rapid pesticide residue detector TY-QN24. The detector 1 is mounted on the top of a counterweight plate 3. An inverted U-shaped assembly plate 4 is welded to the top of the counterweight plate 3. An assembly ring plate 5 is provided between the assembly plate 4 and the counterweight plate 3. Sliding devices for limiting the assembly ring plate 5 are installed on the top of the counterweight plate 3 and the transverse inner wall of the assembly plate 4. Wheel 13, both sides of the assembly ring plate 5 are welded with arc-shaped plates 6. The arc-shaped plates 6 are rotatably connected to the assembly plate 4 through the first rotating shaft. The outer wall of the assembly plate 4 is equipped with a servo motor 7 that provides power to the first rotating shaft. The servo motor 7 drives the first rotating shaft and the arc-shaped plates 6 to rotate, causing the assembly ring plate 5 and the crushing barrel 2 to deflect at a certain angle, thereby changing the tilt angle of the crushing barrel 2. After deflecting at a certain angle for a period of time, the servo motor 7 is controlled to reverse, forming a back-and-forth shaking state, which indirectly improves the uniformity of crushing and indirectly improves the accuracy of pesticide residue detection in agricultural products.

[0028] A rotary motor 8 is installed on the outer wall of the assembly ring plate 5. The output shaft of the rotary motor 8 passes through the assembly ring plate 5 and the crushing barrel 2 and is connected to a rotating rod 9. Multiple movable crushing blades 10 are welded to the outer periphery of the rotating rod 9. Multiple fixed crushing blades 14 adapted to the movable crushing blades 10 are welded to the inner wall of the crushing barrel 2. Multiple stirring blades 15 for stirring agricultural products are also welded to the outer periphery of the rotating rod 9. The stirring blades 15 do not contact the fixed crushing blades 14. When the rotary motor 8 is turned on, the rotary motor 8 drives the rotating rod 9 to rotate, which in turn drives the movable crushing blades 10 to rotate. This allows the movable crushing blades 10 to work with the fixed crushing blades 14 to crush the agricultural products in the crushing barrel 2. The rotation of the stirring blades 15 can stir the existing agricultural products, change the state of the agricultural products, and improve the crushing effect.

[0029] To meet usage requirements, the outer periphery of the crushing barrel 2 is also connected to multiple feed pipes 11 that pass through the assembly ring plate 5. The shape of the feed pipe 11 can also be set to L-shape for easy feeding, and the end can also be set to a pointed shape for easy liquid collection later. The outer periphery of the crushing barrel 2 is connected to a feed pipe 12 with a threaded cap. The agricultural products to be processed and the corresponding reagents and liquids are introduced into the crushing barrel 2 through the feed pipe 12, and then the threaded cap is closed. A control valve is installed on the outer periphery of the feed pipe 11.

[0030] A viewing window is embedded in the outer periphery of the crushing barrel 2.

[0031] The top of the counterweight plate 3 is also equipped with a test tube box 16, which contains multiple test tubes for liquid sampling and testing. The test tubes are for auxiliary work and do not have the function of storing samples. If storage is required, the test tube box 16 needs to fulfill the function of storing samples. After the crushing is completed, the test tubes in the test tube box 16 are taken out, aligned with the designated feed pipe 11, and the control valve of the feed pipe 11 is opened to feed and receive the material. After the necessary auxiliary treatment is performed, the pesticide residue detection of agricultural products is carried out using the detector 1.

[0032] It should be noted that the crushing operation in this application is only one of the operations before testing. For different agricultural products, there should be other supporting treatments, as well as corresponding equipment and functions, such as pre-cleaning, post-filtration, etc. This application will not describe them one by one. This application is an improvement on the shortcomings of crushing in the background technology. In addition, after the test is completed, it is necessary to perform a thorough cleaning before the next operation to avoid cross-contamination.

[0033] Since this application is conducted in a water-rich working environment and involves liquid discharge, all structures and instruments must be treated to prevent water damage and corrosion, especially the instruments, to avoid short circuits or component corrosion, which could reduce the equipment's lifespan.

[0034] The detector 1, servo motor 7, and rotary motor 8 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0036] Working principle

[0037] This agricultural product pesticide residue detection device introduces the agricultural products to be processed, along with corresponding reagents and liquids, into the crushing barrel 2 through the feed pipe 12. After sealing the screw cap, the rotary motor 8 is turned on. The rotary motor 8 drives the rotating rod 9 to rotate, which in turn drives the movable crushing blade 10 to rotate. This allows the movable crushing blade 10, in conjunction with the fixed crushing blade 14, to crush the agricultural products in the crushing barrel 2. The rotation of the stirring blade 15 agitates the existing agricultural products, changing their state and improving the crushing effect. During the crushing process, the servo motor 7 drives the first rotating shaft and the arc plate 6 to rotate, causing the assembly ring plate 5 and the crushing barrel 2 to deflect at a certain angle, thereby changing the tilt angle of the crushing barrel 2. After deflecting at a certain angle for a period of time, the servo motor 7 is controlled to reverse, creating a back-and-forth swaying state, indirectly improving the uniformity of crushing and the accuracy of pesticide residue detection. After crushing is complete, the test tubes in the test tube box 16 are taken out, aligned with the designated feed pipe 11, and the control valve of the feed pipe 11 is opened to feed and receive the materials. After necessary auxiliary processing, the pesticide residues in the agricultural products are detected using the detector 1.

[0038] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
