[0022] 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.

[0023] Please see Figure 1-5This utility model provides an embodiment of a soil sampler, comprising: a handle 01, with rubber sleeves 02 covering the outer walls of both ends of the handle 01; a connecting rod 03 fixedly installed in the lower middle of the handle 01; a fixing plate 04 fixedly installed below the connecting rod 03; the fixing plate 04 can completely remove soil samples from the drill barrel 08, facilitating the preservation and transportation of large quantities of intact soil samples; a fixing rod 05 fixedly installed inside the lower part of the connecting rod 03; a rubber ring 06 provided on the outer wall of the fixing rod 05, which increases damping; and a rotating plate 07 connected to the outer wall of the rubber ring 06. The connecting rod 03 rotates out around the fixed rod 05. The rotating plate 07 and the fixed disk 04 can limit the drill cylinder 08. The drill cylinder 08 is set between the fixed disk 04 and the rotating plate 07. When the drill cylinder 08 is moved away from the grip rod 01, the vent hole can easily discharge the air between the fixed disk 04 and the drill cylinder 08 without affecting the movement of the drill cylinder 08. The upper sides of the drill cylinder 08 are fixedly connected to the upright rods 09. After the upright rods 09 pass through the holes of the grip rod 01, the limiting plate 11 rotates out around the shaft 10 to limit the drill cylinder 08. The shaft 10 is set inside the upper part of the upright rod 09. The limiting plate 11 is connected to the outer wall of the shaft 10.

[0024] The handle 01 has a hole corresponding to the size of the upright 09. After the upright 09 passes through the hole in the handle 01, the limiting plate 11 rotates around the shaft 10 to limit the position of the drill barrel 08. The rubber sleeve 02 is fixedly connected to the handle 01, and the rubber sleeve 02 facilitates the grip of the operator. The diameter of the fixing plate 04 is the same as the inner diameter of the drill barrel 08, ensuring that the fixing plate 04 can push out all the soil samples in the drill barrel 08, thereby cleaning the inner wall of the drill barrel 08. The rubber ring 06 is fixedly connected to the fixing rod 05, and the rubber ring 06 increases the damping effect. The rotating plate 07 is rotatably connected to the rubber ring 06. Rotating the rotating plate 07 around the fixing rod 05 to connect the connecting rod 03, the rotating plate 07 and the fixing plate 04 can limit the position of the drill barrel 08.

[0025] Ventilation holes are provided on both sides of the upper part of the drill cylinder 08. When the drill cylinder 08 is moved away from the handle 01, the ventilation holes can easily expel the air between the fixed plate 04 and the drill cylinder 08 without affecting the movement of the drill cylinder 08. The drill cylinder 08 is slidably connected to the connecting rod 03. When the drill cylinder 08 moves along the outer wall of the connecting rod 03 towards the handle 01, the fixed plate 04 can completely remove the soil sample from the drill cylinder 08, which is convenient for the preservation and transportation of large quantities of intact soil samples. The shaft 10 is fixedly connected to the upright 09 to ensure the firmness of the shaft 10 position. The limiting plate 11 is rotatably connected to the shaft 10. After the upright 09 passes through the hole of the handle 01, the limiting plate 11 can be rotated around the shaft 10 to limit the position of the drill cylinder 08.

[0026] Working principle: When using the device, first hold the rubber sleeve 02 with both hands, insert the drill cylinder 08 into the soil and remove it. Then, rotate the rotating plate 07 around the fixed rod 05 into the connecting rod 03. Hold the drill cylinder 08 with one hand and move it towards the gripping rod 01. The drill cylinder 08 slides on the outer wall of the connecting rod 03, and the fixed plate 04 can completely push out the soil sample from the drill cylinder 08. The pushed-out soil is collected and preserved. At this time, the upright rod 09 passes through the hole in the gripping rod 01, and the limiting plate 11 rotates out around the shaft 10, completing the limiting of the drill cylinder 08. The above is the complete working principle of this utility model.
