[0024] The following details the preferred specific embodiments for implementing the present utility model, and a clear and complete description is made in conjunction with the attached drawings.

[0025] Please refer to Figures 1 - 5 , the present utility model provides a soil sampling device for agricultural promotion.

[0026] It includes a mounting cylinder 100, a sampling device 200 for sampling soil is arranged inside the mounting cylinder 100, and a support device 300 for supporting the mounting cylinder 100 is arranged outside the mounting cylinder 100.

[0027] The sampling device 200 includes a sampling cylinder 220 arranged inside the mounting cylinder 100 for sampling soil. The bottom of the sampling cylinder 220 adopts a conical structure, and the stainless steel at the bottom end of the sampling cylinder 220 is strengthened by quenching to facilitate sampling agricultural soil with the sampling cylinder 220. A driving component 210 for driving the sampling cylinder 220 to move up and down is arranged at the top of the sampling cylinder 220, and an extraction component 230 for extracting the soil in the sampling cylinder 220 is arranged inside the sampling cylinder 220.

[0028] The driving assembly 210 includes a driving rod 211 fixedly installed at the top of the sampling cylinder 220 for driving the sampling cylinder 220 to move up and down. The driving rod 211 penetrates through the top of the installation cylinder 100 and can move up and down within the installation cylinder 100. An anti-collision rod 212 is installed at the top of the driving rod 211 to prevent the driving rod 211 from completely entering the installation cylinder 100. The anti-collision rod 212 reduces the risk of collision with the operator during equipment operation and also prevents the driving rod 211 from falling into the installation cylinder 100.

[0029] An operation plate 213 for driving the driving rod 211 to move up and down is provided on the rod body of the driving rod 211. The operation plate 213 is located above the installation cylinder 100. There are two operation plates 213 in total, and the two operation plates 213 are respectively arranged on both side surfaces of the driving rod 21. The operation plate 213 is made of stainless steel, and the surface of the operation plate 213 is wrapped with an anti-slip rubber sleeve, so that the two operation plates 213 can be used to control the driving rod 211 to drive the sampling cylinder 220 to take samples from the soil. A fixing plate 214 for restricting the extraction assembly 230 is fixedly installed on the rod body of the driving rod 211, and the fixing plate 214 is located inside the cavity of the installation cylinder 100.

[0030] The extraction assembly 230 includes a moving plate 234 provided inside the cavity of the sampling cylinder 220 for ejecting the soil inside the sampling cylinder 220. The cross-section of the moving plate 234 is circular, and the diameter of the moving plate 234 is the same as the inner diameter of the sampling cylinder 220, so that the soil inside the sampling cylinder 220 can be ejected by the up and down movement of the moving plate 234, and thus the sampling of agricultural soil can be completed. A moving rod 233 for driving the moving plate 234 to move up and down is fixedly installed at the top of the moving plate 234, and the moving rod 233 penetrates through the plate body of the fixing plate 214.

[0031] A driving plate 231 for driving the moving rod 233 to move up and down is fixedly installed at the top of the moving rod 233. A locking rod 232 for locking the driving plate 231 is provided on the plate body of the driving plate 231, and the locking rod 232 is threadedly connected to the driving rod 211. Therefore, when sampling agricultural land soil, the installation cylinder 100 can be placed on the soil surface, and then the installation cylinder 100 can be supported by the support device 300. Then, by driving the driving rod 211 to move downwards through the two operation plates 213, the sampling cylinder 220 can be moved into the soil to complete the soil sampling. Then, the installation cylinder 100 is taken out. At this time, the sampling cylinder 220 is moved out of the installation cylinder 100 through the two operation plates 213. Finally, the locking rod 232 is removed from the driving plate 231 to release the locking of the driving plate 231, and then the moving plate 234 at the bottom of the moving rod 233 is driven by the driving plate 231 to eject the soil inside the sampling cylinder 220, so that the soil sampling can be quickly completed.

[0032] The supporting device 300 includes hinge blocks 320 fixedly installed on the outer side of the installation cylinder 100, and there are three hinge blocks 320. The three hinge blocks 320 are distributed in a circumferential array on the cylinder wall of the installation cylinder 100. A supporting component 310 for supporting the installation cylinder 100 is movably connected inside the hinge block 320.

[0033] The supporting component 310 includes a hinge rod 311 movably connected to the hinge block 320. A plug rod 312 for inserting into the soil to support the installation cylinder 100 is fixedly installed at the bottom end of the hinge rod 311. Thus, when it is necessary to support the installation cylinder 100, the hinge rod 311 can be rotated around the hinge block 320, and then the plug rod 312 is inserted into the soil to complete the support of the installation cylinder 100.
