[0002] Soil refers to a loose layer of material on the Earth's surface, composed of various granular minerals, organic matter, water, air, microorganisms, and the like, capable of supporting plant growth. Soil is composed of minerals formed from weathered rocks, organic matter from the decomposition of plant and animal remains, microbial remains, soil organisms (solid phase), water (liquid phase), air (gaseous phase), and oxidized humus. Soil testing typically involves sampling with a soil sampler, a device used to obtain soil from the ground.

[0003] The existing soil sampler requires manual sampling when in use, which results in manual sampling when the device is used, and sampling is very laborious. At the same time, during the sampling process, the soil is prone to falling in the middle of the sample, affecting the final sampling effect. Based on this, the present invention provides a retractable soil detection sampling device to solve the above-mentioned problems. Utility Model Content

A drill bit 10 is provided at the lower end of the sampling tube 9, which is driven by the rotating motor 5 to rotate the drill bit 10 and cooperate with the electric telescopic rod 7 to make the sampling tube 9 enter the ground. Then the electric cylinder 12 is started to drive the lifting block 13 to descend. Then, through the action of the connecting rod 17, the connecting rod 17 pushes the push rod 16 to move, and then the scraper 15 rotates outward, so that during the rotation of the sampling tube 9, the surrounding soil samples are introduced into the sampling tube 9 through the scraper 15. When the sampling is completed, the electric cylinder 12 is reset and the scraper 15 is stored back into the sampling port 901, thereby storing the soil sample inside the sampling tube 9 to prevent the soil sample from falling due to the vibration of the machine.

[0021] Specifically, in this embodiment, the lower end surface of the sampling barrel 9 is provided with a plurality of sampling ports 901. A scraper 15 is rotatably mounted within each sampling port 901, and a push rod 16 is fixedly connected to the inner end of each scraper 15. The push rod 16 controls the rotation of the scraper 15. When the scraper 15 rotates out of the sampling port 901, it scrapes the surrounding soil layer, allowing the soil sample to enter the sampling barrel through the sampling port 901. When sampling is completed, the scraper 15 returns to the sampling port 901, sealing the sampling port 901 and preventing the soil sample from falling out of the sampling barrel 9.

[0022] Specifically, in this embodiment, a fixing plate 11 is fixedly connected to the upper side of the inner wall of the sampling tube 9, an electric cylinder 12 and a battery 18 are fixedly installed on the upper end of the fixing plate 11, and the output end of the electric cylinder 12 passes through the fixing plate 11 and is fixedly connected to the lifting block 13.

[0023] Specifically, in this embodiment, the lower end of the lifting block 13 is fixedly connected to the guide rod 1301, the lower end of the guide rod 1301 is slidably connected to the inner wall of the guide column 14, the guide column 14 is fixedly connected to the bottom of the lower end of the sampling tube 9, and the four side walls of the lifting block 13 are fixedly installed with a first hinged seat.

[0024] Specifically, in this embodiment, the lifting block 13 is hinged to four connecting rods 17 via a first hinge seat. The other end of the connecting rod 17 is hinged to the push rod 16 via a second hinge seat, and the second hinge seat is fixedly mounted on the inner side of the upper end of the push rod 16. The connecting rod 17 and the two hinge seats are both spherical hinges, which have a high degree of freedom and can achieve a larger angle of rotation, thereby facilitating the rotation of the scraper 15. When the electric cylinder 12 is activated, it drives the lifting block 13 downward. Subsequently, the connecting rod 17 pushes the push rod 16 to move, causing the scraper 15 to rotate outward. As the sampling barrel 9 rotates, the surrounding soil sample is introduced into the sampling barrel 9 through the scraper 15.

[0025] The working principle of the present utility model is as follows: a worker places the device at the location to be sampled and then starts the device. A drill bit 10 is provided at the lower end of the sampling tube 9. The drill bit 10 is driven by the rotating motor 5 to rotate and cooperate with the electric telescopic rod 7 to make the sampling tube 9 enter the ground. Then the electric cylinder 12 is started to drive the lifting block 13 to descend. Then, through the action of the connecting rod 17, the connecting rod 17 pushes the push rod 16 to move, thereby causing the scraper 15 to rotate outward, so that during the rotation of the sampling tube 9, the surrounding soil samples are introduced into the sampling tube 9 through the scraper 15.

[0026] Among them, the connecting rod 17 and the two hinged seats are spherical hinges with a high degree of freedom, which can achieve a larger angle of rotation, thereby facilitating the rotation of the scraper 15. When the electric cylinder 12 is started, the lifting block 13 is driven to descend, and then the connecting rod 17 is used to push the push rod 16 to move, thereby causing the scraper 15 to rotate outward, so that during the rotation of the sampling tube 9, the surrounding soil samples are introduced into the sampling tube 9 through the scraper 15. When the sampling is completed, the electric cylinder 12 is reset and the scraper 15 is stored back into the sampling port 901, thereby storing the soil sample inside the sampling tube 9 to prevent the soil sample from falling due to the vibration of the machine.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
