[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Embodiment 1

[0025] See also Figure 1-4 , a pesticide detection sampling device for agricultural products, including a body 1, the main frame of the entire device, supporting the installation and operation of other components, providing a stable structural foundation, the bottom of the body 1 is provided with moving wheels 2, so that the device can be easily moved in different places, increasing the mobility of the equipment, and the inner side of the body 1 is provided with a sampling component 3; The sampling assembly 3 includes a cylinder 31, which is used to drive the up and down movement of the device, control the up and down adjustment of the mounting plate 32 and other components, and is fixedly connected to the upper end of the vehicle body 1. The output end of the cylinder 31 is fixedly connected to the mounting plate 32, and the bottom of the mounting plate 32 is fixedly connected to a motor 33. The output end of the motor 33 is fixedly connected to a sampling barrel 34, which is a main component for collecting samples. It completes the sampling of soil or agricultural products by rotating and moving. The bottom of the sampling barrel 34 is fixedly connected to a scraper 35, and the bottom of the sampling barrel 34 is opened. A sampling port 36 is provided, which is the opening for soil to enter the sampling tube 34 and has a switch function to ensure the accuracy of the sampling process. A rotating ring 37 is rotatably connected to the bottom end of the inner part of the sampling tube 34, and a baffle 38 is fixedly connected to the outer wall of the rotating ring 37. The baffle 38 is used to block or open the sampling port 36 to control whether the soil can enter the sampling tube 34. A limiting rod 39 is fixedly connected to the bottom end of the inner part of the sampling tube 34 to limit the rotation range of the rotating ring 37 and the baffle 38, ensuring that the rotation of the baffle 38 does not exceed a predetermined range. The size of the baffle 38 is larger than the size of the sampling port 36, thereby ensuring that the baffle 38 can completely cover the sampling port 36 when blocking it. One side of the sampling port 36 is set as an inclined surface, thereby allowing the sampled soil to enter the interior of the sampling tube 34 more smoothly.

[0026] During use, when sampling is required, the motor 33 is first started to drive the sampling tube 34 to rotate clockwise, and then the rotating ring 37 inside the sampling tube 34 will also rotate clockwise under the inertia of its side baffle 38, and then the baffle 38 will rotate clockwise to the upper end of the sampling port 36, and then the upper end of the sampling port 36 can be blocked, and then the mounting plate 32 can be driven down by the cylinder 31, and the motor 33 and the sampling tube 34 will descend accordingly. When the scraper 35 at the bottom of the sampling tube 34 contacts the soil surface, at this time, since the sampling port 36 is in a closed state, the soil will not enter the interior of the sampling tube 34 through the sampling port 36, but will be pushed to the outside of the sampling tube 34. When the sampling tube 34 descends to the required After the sampling depth is reached, the motor 33 drives the sampling tube 34 to rotate counterclockwise. Similarly, the rotating ring 37 will also rotate counterclockwise under the inertia of its side baffle 38, and then the baffle 38 will rotate counterclockwise from the upper end of the sampling port 36, so that the sampling port 36 can be opened. It should be noted that no matter which direction the baffle 38 rotates, the limit rod 39 can play a limiting role. Since the sampling port 36 is initially in an open state, the scraper 35 at the bottom of the sampling tube 34 can push the soil into the interior of the sampling tube 34 during the rotation. When the sampling is completed, the motor 33 continues to rotate clockwise, and the sampling port 36 is blocked by the baffle 38, and the sampling tube 34 can be driven to rise by the cylinder 31. Embodiment 2

[0027] See also Figure 1-6 A knocking assembly 4 is provided inside and on both sides of the sampling tube 34. The knocking assembly 4 includes a connecting rod 41, which is fixedly connected to the upper end of the rotating ring 37. The upper end of the connecting rod 41 is rotatably connected to a connecting rod A42, and the other end of the connecting rod A42 is rotatably connected to a connecting rod B43 through a pin shaft. The other end of the connecting rod B43 slides through the sampling tube 34. A fixing plate 44 is fixedly connected to the inner wall of the vehicle body 1, and the upper end of the fixing plate 44 is rotatably connected to a rotating block through a pin shaft. A45 and a rotating plate 47, the outer wall of the rotating plate 47 is hinged with a rotating block B48, a telescopic rod A46 is fixedly connected between the rotating block A45 and the rotating block B48, the upper end and the side of the rotating plate 47 are respectively fixedly connected with a fixed block A49 and a fixed block B410, and the fixed block B410 is fixedly connected with a knocking rod 411 on the side close to the sampling tube 34, and the knocking rod 411 is used to knock the sample out of the sampling tube 34 after sampling to accelerate the discharge of soil or samples. The outer wall of the telescopic rod A46 is movably sleeved with a spring 412, and the two ends of the spring 412 are respectively fixedly connected to the rotating block A45 and the rotating block B48, and the spring 412 provides a restoring force to ensure the resetting of the rotating block. The knocking assembly 4 is provided with two groups and is centrally symmetrically distributed with the center of the sampling tube 34 as the midpoint.

[0028] When in use, after sampling is completed and the sampling tube 34 moves to a certain height, the sampled soil inside the sampling tube 34 needs to be taken out. At this time, the baffle 38 needs to release the obstruction of the sampling port 36, so the motor 33 needs to drive the sampling tube 34 to rotate counterclockwise, and the rotating ring 37 inside it will also rotate counterclockwise, thereby driving the connecting rod A41 at the upper end of the rotating ring 37 to rotate accordingly, and then the connecting rod A41 will push the connecting rod B43 to slide outward through the connecting rod A42, and then when the connecting rod A42 moves to the side of the fixed block A49, the motor 33 drives the sampling tube 34 to rotate and drives the connecting rod B43 to rotate at the same time, and the connecting rod B4 During the rotation, the connecting rod B43 will intermittently contact with the fixed block A49. When they are in contact, the rotating plate 47 will be pushed to rotate outward, and then the rotating block B48 will also rotate inward, and squeeze the telescopic rod A46 and the spring 412 between it and the fixed block A49 to shrink. When the outer end of the connecting rod B43 is not in contact with the fixed block, the spring A412 and the telescopic rod A46 cooperate to make the rotating block B48 and the rotating plate 47 rotate and reset and rotate to the sampling tube 34 within a certain range, so that the knocking rod 411 on the outer wall of the fixed block B410 at the upper end of the rotating plate 47 can be driven to knock the sampling tube 34, thereby increasing the speed of discharging the sampled soil inside the sampling tube 34. Embodiment 3

[0029] See also Figure 1-7The sampling tube 34 is provided with a water spraying assembly 5 on its outside, which can soften the soil by spraying water to ensure a smooth drilling process, and can adjust the spraying range during the sampling process to maintain a constant water volume, thereby further optimizing the sampling environment. The water spraying assembly 5 includes a fixing ring 51, which is fixedly sleeved on the outer wall of the sampling tube 34, and a water tank 52 is fixedly connected to the bottom of the fixing ring 51, and a connecting hose 53 is fixedly connected to the bottom of the water tank 52, and a nozzle 54 is fixedly connected to the other end of the connecting hose 53, which is responsible for spraying water evenly onto the soil surface to soften the soil for easy drilling. A telescopic rod B55 is fixedly connected to the bottom of the fixing ring 51, and the outer wall of the telescopic rod B55 is fixedly connected to the bottom of the fixing ring 51. The fixed sleeve is provided with a fixed sleeve 56, and the outer wall of the fixed sleeve 56 is rotatably connected with a rotating shaft A57 and a rotating shaft B510, and the end of the rotating shaft A57 away from the fixed sleeve 56 is fixedly connected to the nozzle 54, and the outer wall of the rotating shaft A57 is fixedly sleeved with a collar 58, and the upper end of the collar 58 is fixedly connected with a swing rod 59, and the end of the rotating shaft B510 away from the fixed sleeve 56 is fixedly connected with a connecting block 511, and the outer wall of the connecting block 511 is rotatably connected with a movable ring 512 through a pin shaft, and the movable ring 512 is movably sleeved on the outer wall of the swing rod 59, and the bottom of the fixed ring 51 is fixedly connected with a tooth plate 513, and the outer wall of the rotating shaft B510 is fixedly sleeved with a gear 514. The gear 514 is located on the side of the tooth plate 513 and meshes with it.

[0030] During use, when the sampling tube 34 is lowered to contact the ground, the water in the water tank 52 can be transported to the nozzle 54 through the connecting hose 53, and the soil is sprayed with water through the nozzle 54 to make the soil layer softer, thereby facilitating soil drilling. At the same time, when the bottom of the sampling tube 34 contacts the ground, the telescopic rod B55 at the bottom of the fixing ring 51 will also contact the ground. When the sampling tube 34 moves toward the lower end of the ground, the telescopic rod B55 will be compressed, which will drive the fixed sleeve 56 on its outer wall to rise, and then the nozzle 54 can be driven to rise through the rotating shaft A57, thereby ensuring that the nozzle 54 is always at the same distance from the soil surface. When 56 rises, it will drive the rotating shaft B510 and the gear 514 to rise. Since the gear 514 is meshed with the tooth plate 513, the gear 514 will rotate while rising, and the rotating shaft B510 will rotate accordingly, and then drive the connecting block 511 to rotate, and then the connecting block 511 will drive the movable ring 512 to rotate around the rotating shaft B510. When the movable ring 512 rotates, it will slide on the outer wall of the swing rod 59, so that the swing rod 59 can swing. When the swing rod 59 swings left and right, it will drive the sprinkler head 54 to swing left and right within a certain range through the rotating shaft A57, so as to ensure the range of water spraying.
