To ensure that pesticide residue levels in agricultural products meet standards, accurate testing of crop residues is necessary.

[0003] In the prior art, the utility model patent with patent publication number CN220188353U discloses a pesticide residue detection device for agricultural products. This device uses a plug-in method to set the material cylinder inside the shell and a split splicing method to connect the material cylinder and the agitator. This allows the entire mechanism for crushing and mixing agricultural products to be easily disassembled and assembled, so that it can be quickly removed after use and cleaned independently, thus achieving the effect of convenient disassembly and cleaning.

[0004] However, the pesticide residue detection device in the aforementioned patent still has certain drawbacks in use. When conducting pesticide residue detection on agricultural products, the height of the device cannot be adjusted according to the actual situation, making it inconvenient for staff of different heights to use and causing inconvenience to staff when detecting pesticide residues on agricultural products. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pesticide residue detection device for agricultural products, which can adjust the height of the device according to the actual situation so that it can be used by staff of different heights, bringing convenience to staff when detecting pesticide residues in agricultural products.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pesticide residue detection device for agricultural products, comprising a housing, a PLC controller inside the housing, a display screen and buttons electrically connected to the PLC controller on the top of the housing, a stirrer detachably connected to the housing, and a support structure and an adjustment mechanism. The support structure includes a platform, four sets of guide rods symmetrically fixed at the bottom of the platform, each set of guide rods having a slidable support leg, a positioning frame fixedly connected to the top of the platform, and rubber clamps symmetrically fixed on the inner walls of the left and right sides of the positioning frame. The housing cooperates with the rubber clamps... The device is mounted on a positioning frame, with the bottom of the housing in contact with the top of the platform. The adjustment mechanism includes a transmission worm gear. Two sets of support plates are fixedly connected to the bottom of the platform. The transmission worm gear is rotatably mounted on the two sets of support plates. A handwheel is provided at the front end of the transmission worm gear. Two sets of fixing plates are symmetrically fixed on the left and right sides of the bottom of the platform. A transmission rod is rotatably mounted on the two sets of fixing plates. A worm wheel is fixedly sleeved in the middle of the transmission rod, and the worm wheel meshes with the transmission worm gear. Support plates are symmetrically fixedly connected to both ends of the transmission rod. U-shaped support grooves are fixedly connected to the two sets of support legs on the left and the two sets of support legs on the right. The bottom ends of the two sets of support plates abut against the inside of the two sets of U-shaped support grooves, respectively.

[0008] Preferably, a sleeve is fixedly provided at the middle of the rear end of the handwheel, and a socket is provided at the rear end of the sleeve to cooperate with the transmission worm gear. A slot is provided at the bottom of the socket. A locking block is fixedly provided at the front end of the transmission worm gear.

[0010] Preferably, the handwheel has multiple hanging holes arranged in a circular array, and a hook is fixedly provided at the front end of the platform.

[0011] Preferably, a crank handle is rotatably provided at the front edge of the handwheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the housing is first clamped into the positioning frame. During clamping, the rubber clamps on both sides of the housing are squeezed, causing the rubber clamps to generate elasticity, thus stabilizing the housing on the platform. Initially, the transmission rod rests on two sets of U-shaped support grooves, and the platform is in its lowest position. When height adjustment is needed, the transmission worm is rotated via the handwheel, causing the transmission worm to mesh with the worm wheel, driving the transmission rod to rotate. This causes the transmission rod to rotate the support plate downwards, so that the bottom of the support plate abuts against the inside of the U-shaped support groove. The downward rotation of the support plate pushes the platform, causing the platform to slide upwards along the guide rod, raising the platform height. This, in turn, raises the housing. Furthermore, the engagement between the transmission worm and the worm wheel has a self-locking function, preventing the worm wheel from rotating on its own. After the platform is raised, it remains stable and does not fall down. This allows the device's height to be adjusted according to actual conditions, facilitating use by personnel of different heights and providing convenience for workers testing pesticide residues in agricultural products.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] Example

[0023] Please see Figures 1-7 This utility model discloses a pesticide residue detection device for agricultural products, comprising a housing 1, inside which is a PLC controller. The top of the housing 1 has a display screen 2 and buttons 3 electrically connected to the PLC controller. A stirrer 4 is detachably connected to the housing 1. The device also includes a support structure and an adjustment mechanism. The support structure includes a platform 5, with four sets of guide rods symmetrically fixed at the bottom of the platform 5. Each of the four sets of guide rods 6 has a slidably fitted support leg 7. A positioning frame 8 is fixedly connected to the top of the platform 5. Rubber clips 9 are symmetrically fixed on the inner walls of the left and right sides of the positioning frame 8. The housing 1 is engaged with the rubber clips 9. Mounted on the positioning frame 8, the bottom end of the housing 1 contacts the top end of the platform 5. The adjustment mechanism includes a transmission worm gear 10. Two sets of support plates 11 are fixedly connected to the bottom end of the platform 5. The transmission worm gear 10 is rotatably mounted on the two sets of support plates 11. A handwheel 12 is provided at the front end of the transmission worm gear 10. Two sets of fixing plates 13 are symmetrically fixed on the left and right sides of the bottom end of the platform 5. A transmission rod 14 is rotatably mounted on the two sets of fixing plates 13. A worm wheel 15 is fixedly sleeved in the middle of the transmission rod 14. The worm wheel 15 meshes with the transmission worm gear 10. Support plates 16 are symmetrically fixedly connected to both ends of the transmission rod 14. Support plates 16 are fixedly mounted on the two sets of support legs 7 on the left and the two sets of support legs 7 on the right. The housing 1 is fixedly connected to a U-shaped support groove 17, and the bottom ends of the two sets of support plates 16 respectively abut against the inside of the two sets of U-shaped support grooves 17. In use, the housing 1 is first clamped into the positioning frame 8. During clamping, the two sides of the housing 1 are squeezed against the rubber clamping strips 9, so that the rubber clamping strips 9 generate elasticity, thereby making the housing 1 stably placed on the platform 5. Initially, the transmission rod 14 rests on the two sets of U-shaped support grooves 17, and the platform 5 is in the lowest position. When the height needs to be adjusted, the transmission worm gear 10 is rotated by the handwheel 12, so that the transmission worm gear 10 drives the transmission rod 14 to rotate through the meshing with the worm wheel 15, thereby causing the transmission rod 14 to drive the support plates 16 towards the platform 5. The downward rotation causes the bottom of the support plate 16 to abut against the inside of the U-shaped support groove 17. The downward rotation of the support plate 16 pushes the platform 5, causing the platform 5 to slide upward along the guide rod 6, raising the height of the platform 5. This, in turn, raises the housing 1. The transmission worm 10 and worm wheel 15 have a self-locking function, preventing the worm wheel 15 from rotating on its own. After the platform 5 is raised, it remains stable and does not fall down. This allows the device's height to be adjusted according to actual conditions, facilitating use by workers of different heights and providing convenience for workers testing pesticide residues in agricultural products.

[0024] A sleeve 18 is fixedly provided at the middle of the rear end of the handwheel 12. The rear end of the sleeve 18 has a socket that mates with the transmission worm gear 10. A slot is provided at the bottom of the socket. A locking block 19 is fixedly provided at the front end of the transmission worm gear 10. The locking block 19 is integrally formed with the transmission worm gear 10. The sleeve 18 is detachably fitted onto the transmission worm gear 10 through the socket, and the locking block 19 is engaged in the slot. In use, the sleeve 18 is fitted onto the transmission worm gear 10, so that the locking block 19 is engaged in the slot. The height of the platform 5 can be adjusted by rotating the transmission worm gear 10 through the handwheel 12. After the height is adjusted, the sleeve 18 can be pulled off the transmission worm gear 10, and the handwheel 12 can be removed to prevent accidental contact with the handwheel 12 that could cause the transmission worm gear 10 to rotate.

[0025] Both sides of the top of the two sets of U-shaped support grooves 17 are symmetrically fixedly connected with limiting plates 22; by setting the limiting plates 22, they can block the support strip 16, forming a limit on the support strip 16, and preventing the support strip 16 from separating from the U-shaped support groove 17 during rotation.

[0026] The handwheel 12 is provided with a plurality of hanging holes 20 arranged in a ring, and a hook 21 is fixedly provided at the front end of the platform 5. After the handwheel 12 is removed, it can be hung on the hook 21 through the hanging holes 20 so that it can be taken down and used at any time, avoiding the situation of being lost when it is placed down.

[0027] A crank handle 23 is rotatably provided at the front edge of the handwheel 12; by providing the crank handle 23, the handwheel 12 can be rotated more conveniently.

[0028] This utility model discloses a pesticide residue detection device for agricultural products. In operation, the housing 1 is first inserted into the positioning frame 8. During insertion, the rubber clamping strips 9 on both sides of the housing 1 are compressed, causing them to spring and stabilize the housing 1 on the platform 5. Initially, the transmission rod 14 rests on two sets of U-shaped support grooves 17, and the platform 5 is in its lowest position. When height adjustment is needed, the transmission worm gear 10 is rotated via the handwheel 12. This worm gear 10, through meshing with the worm wheel 15, drives the transmission rod 14 to rotate, which in turn causes the transmission rod 14 to rotate downwards, causing the support plate 16 to rotate downwards. The bottom of the 6-shaped support is abutted against the inside of the U-shaped support groove 17. The support bar 16 rotates downward to push the platform 5, which in turn causes the platform 5 to slide upward along the guide rod 6, raising the height of the platform 5. This, in turn, raises the housing 1. The transmission worm 10 and worm wheel 15 have a self-locking function, preventing the worm wheel 15 from rotating on its own. After the platform 5 is raised, it remains stable and does not fall down. Once the height of the housing 1 is adjusted, the handwheel 12 is removed and hung on the hook 21 to prevent accidental contact with the handwheel 12 that could cause the transmission worm 10 to rotate, thus ensuring height stability.
