[0002] To prevent the overuse of pesticides, pesticide residues in areas where pesticides have been sprayed need to be tested to avoid repeated application of pesticides to the same plot of land.
[0003] The authorized publication number "CN219142258U" describes "a soil pesticide residue detection sampling device, including a column, a lifting assembly installed inside the column, a horizontal plate slidably connected to the side of the lifting assembly away from the column, a lifting rod assembly installed above the horizontal plate, a fixed plate slidably connected to the lifting rod assembly, a transmission mechanism fixedly installed above the fixed plate, a rotating cylinder rotatably connected below the fixed plate, the top of the rotating cylinder fixedly connected to the transmission mechanism, and the bottom of the rotating cylinder penetrating the horizontal plate; a vertical rod slidably connected to the end of the horizontal plate away from the column, and an anchoring assembly fixedly installed at the bottom of the vertical rod. This utility model can achieve sampling of the soil surface and soil interior by the rotating cylinder; moreover, with the column as the center, rotating with a radius of the distance from the rotating cylinder on the horizontal plate to the column, it can achieve multi-point sampling of the soil in the area, avoiding the need for repeated fixing as in traditional sampling devices, improving the accuracy of sampling locations and the precision of soil sample detection."
[0004] The aforementioned patents effectively improve the sampling accuracy of the sampling device, but in practical applications, the patents are large in size and complex in structure, which can easily lead to cumbersome changes in sampling locations and affect sampling efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A pesticide residue detection and sampling device includes:
[0008] Mounting plate, the top of which is fixedly mounted a handle; and
[0009] The sampling mechanism includes a drilling shaft, which is rotatably embedded in the center of the outer wall of the mounting plate. A spiral conveying blade is installed on the outer surface of the drilling shaft. Two limiting rods are fixedly installed at the bottom of the mounting plate. A limiting slider is movably sleeved on the outer surface of each limiting rod.

[0014] As a preferred embodiment of this utility model, anti-slip strips are fixedly connected at equal intervals on the outer surface of the grip.
[0015] Beneficial effects
[0016] Compared with existing technologies, this utility model provides a pesticide residue detection and sampling device, which has the following beneficial effects:
[0017] 1. In this solution, the handle facilitates the carrying of the mounting plate and sampling mechanism, enabling quick replacement when changing sampling locations and improving the efficiency of soil sampling in areas with pesticide residues. The drilling shaft on the mounting plate rotates, and pressing down the mounting plate 1 facilitates the spiral conveyor blade to follow the drilling shaft into the soil. The rotation of the spiral conveyor blade facilitates the expulsion of soil. The limiting slider slides on the limiting rod, facilitating the lifting and lowering of the sampling tube, which works in conjunction with the spiral conveyor blade to sample the soil, further improving the efficiency of the sampling mechanism.
[0018] 2. In this design, the abutment spring ensures that the limiting slider always moves downwards, which facilitates the reset of the sampling tube and the recycling of the sampled soil. The L-shaped hook allows the sampling tube to be fixed near the mounting plate, preventing it from resetting for a certain period of time. This also facilitates the preservation of soil samples between the spiral conveyor and the sampling tube, improving the safety of the sampling mechanism. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0025] Example:
[0026] Please see Figure 1-3 A pesticide residue detection and sampling device, comprising:
[0027] Mounting plate 1, with a handle 2 fixedly mounted on its top; and
[0028] The sampling mechanism 3 includes a drilling shaft 301, which is rotatably embedded in the center of the outer wall of the mounting plate 1. A spiral conveying blade 302 is installed on the outer surface of the drilling shaft 301. Two limiting rods 303 are fixedly installed at the bottom of the mounting plate 1. A limiting slider 304 is movably sleeved on the outer surface of each limiting rod 303. A sampling tube 305 is fixedly installed between the outer walls of the two limiting sliders 304, and the sampling tube 305 is sleeved on the outer surface of the spiral conveying blade 302.
[0029] In this embodiment, the handle 2 facilitates the carrying of the mounting plate 1 and the sampling mechanism 3, enabling quick replacement when changing sampling locations and improving the efficiency of soil sampling in areas with pesticide residues. The drilling shaft 301 on the mounting plate 1 rotates, pressing down the mounting plate 1, which facilitates the driving of the spiral conveyor blade 302 to follow the drilling shaft 301 into the soil. The rotation of the spiral conveyor blade 302 facilitates the expulsion of soil. The limiting slider 304 slides on the limiting rod 303, which facilitates the lifting and lowering of the sampling tube 305, allowing it to work with the spiral conveyor blade 302 to sample the soil, further improving the efficiency of the sampling mechanism 3.
[0030] Please refer to the specific details. Figure 1 As shown, a drive motor 4 is fixedly installed on the top of the mounting plate 1, and the output end of the drive motor 4 is fixedly connected to one end of the drilling shaft 301.
[0031] In this embodiment, the drive motor 4 facilitates the rotation of the drilling shaft 301, thereby improving the ease of use of the sampling mechanism 3.
[0032] Please refer to the specific details. Figure 1 As shown, each limiting slider 304 is connected to an abutment spring 5 between itself and the outer wall of the mounting plate 1.
[0033] In this embodiment, the abutment spring 5 facilitates the downward movement of the limiting slider 304, thereby facilitating the reset of the sampling tube 305 and the recycling of the sampled soil.
[0034] Please refer to the specific details. Figure 1 As shown, the top of the sampling tube 305 is hinged with multiple L-shaped hooks 6.
[0035] In this embodiment, the L-shaped hook 6 has a certain degree of elasticity. The sampling tube 305 can be easily fixed at a position close to the mounting plate 1 by the L-shaped hook 6, which can prevent the sampling tube 305 from resetting for a certain period of time. This facilitates the preservation of soil samples between the spiral conveyor blade 302 and the sampling tube 305, and improves the safety of the sampling mechanism 3.
[0036] Please refer to the specific details. Figure 1 As shown, each L-shaped hook 6 has an anti-slip block 7 fixedly connected to its outer wall, and the top of the mounting plate 1 has multiple corresponding grooves.
[0037] In this embodiment, the stability of the L-shaped hook 6 is improved by the cooperation of the anti-slip block 7 and the corresponding groove.
[0038] Please refer to the specific details. Figure 2-3 As shown, anti-slip strips 8 are fixedly connected at equal intervals on the outer surface of the grip 2.
[0039] In this embodiment, the anti-slip effect of the grip 2 is improved by using the anti-slip strip 8.
[0040] Working principle: During use, the handle 2 facilitates the carrying of the mounting plate 1 and the sampling mechanism 3. During sampling, the bottom ends of the drilling shaft 301 and the sampling tube 305 are pressed against the area to be sampled. The handle 2 is used to press down on the mounting plate 1 and start the drive motor 4. The drive motor 4 drives the drilling shaft 301 to rotate, which in turn drives the spiral conveyor blade 302 to rotate. During downward pressure, the drilling shaft 301 drives the spiral conveyor blade 302 into the soil. At this time, the bottom of the sampling tube 305 presses against the ground. Under the constraint of the sampling tube 305, the soil sample continuously enters the spiral conveyor blade 305. In the space between the drilling shaft 301 and the sampling tube 305, when the drilling shaft 301 descends, it will drive the sampling tube 305 to slide on the limiting rod 303 along with the limiting slider 304, and continue to approach the mounting plate 1 to a suitable position, hang multiple L-shaped hooks 6, so that the anti-slip block 7 is embedded in the corresponding groove. At this time, turn off the drive motor 4, and pull out the drilling shaft 301 and the spiral conveyor blade 302. When it is necessary to take out the sample, remove the L-shaped hooks 6, and under the action of the abutment spring 5, drive the sampling tube 305 to reset, and recover the soil sample on the spiral conveyor blade 302.
[0041] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
