[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides the following technical solution: a safe and environmentally friendly sampling device for herbicide pesticide production, comprising: a sampling tube 1, the top of which has an opening, and a conical suction tube 2 fixedly connected to the bottom of the sampling tube 1, with a tube cap 7 sleeved on the bottom of the conical suction tube 2; a piston plate 3, which is movably inserted into the inside of the sampling tube 1; a drive housing 4, which is rotatably sleeved on the outer wall of the bottom of the sampling tube 1, with a lead screw 5 fixed inside the drive housing 4, the lead screw 5 passing through the piston plate 3 and being threadedly connected to the piston plate 3; a sealing holding sleeve 6, which is fixedly sleeved on the outer wall of the bottom of the sampling tube 1, and the bottom of the drive housing 4 is rotatably inserted into the inside of the sealing holding sleeve 6; and a sealing cone 8 inside the tube cap 7, which is movably inserted into the inside of the conical suction tube 2 for sealing the conical suction tube 2. A limiting ring 9 is provided at the bottom of the inner part of the drive housing 4. A corresponding limiting ring groove is formed on the outer wall of the sampling tube 1, and the limiting ring 9 is embedded in the limiting ring groove to limit the distance between the sampling tube 1 and the drive housing 4. A first sealing ring 10 is provided between the two limiting rings 9 and is embedded between the sampling tube 1 and the drive housing 4 to improve the sealing performance between the sampling tube 1 and the drive housing 4. A second sealing ring 11 is embedded between the sealing holding sleeve 6 and the drive housing 4 to improve the sealing performance between the drive housing 4 and the sealing holding sleeve 6. Anti-slip grooves are formed on the outer wall of the drive housing 4, the outer wall of the sealing holding sleeve 6, and the outer wall of the tube cap 7.

[0017] Specifically, in the initial state, the tube cap 7 is threaded onto the outer wall of the conical suction tube 2, and the sealing cone 8 is inserted into the interior of the conical suction tube 2; When in use, unscrew the tube cap 7 to rotate the drive housing 4. When the drive housing 4 rotates, it can synchronously drive the screw 5 to rotate. When the screw 5 rotates, it can drive the threaded piston plate 3 to rise and fall along the inner wall of the sampling tube 1. When the piston plate 3 rises, it can draw the pesticide agent through the opening at the bottom of the conical suction tube 2 into the interior of the sampling tube 1. After sampling is completed, tighten the tube cap 7. While tightening the tube cap 7, simultaneously insert the sealing cone 8 into the opening at the bottom of the conical suction tube 2 to seal the conical suction tube 2 and prevent drug leakage.

[0018] During the storage or transportation of the sampling device, the opening at the bottom of the conical suction tube 2 is closed, and the friction between the drive housing 4 and the sampling tube 1 is increased by the limiting ring 9, preventing the drive housing 4 from rotating accidentally. Furthermore, a first sealing ring 10 and a second sealing ring 11 are respectively provided between the drive housing 4 and the sampling tube 1 and between the sampling tube 1 and the sealing holding sleeve 6, which greatly enhances the sealing performance of the device, ensuring that the sample inside the device will not leak and ensuring the safety of the sample.
