[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to solve the problem that the ecological and environmental protection deep soil sampling device is inconvenient to sample soil at different depths when used, which reduces the sampling accuracy of the soil, please refer to Figures 1 to 5 The structure of the device body is as follows: a sampling tube 1, the inner wall of the sampling tube 1 is slidably connected to a sealing plate 2, the sampling tube 1 is set to fix the moving path of the sealing plate 2, and the sealing plate 2 is sealed at the connection between the inner wall of the sampling tube 1 to improve the functional structural stability of the soil sampler, the top and bottom ends of the sealing plate 2 are respectively fixedly connected to a movable rod 4 and a conical drill 3, the conical drill 3 is set to reduce the direct contact area with the soil, and it is convenient for the soil sampler to extend into the soil during the transmission process, the side of the movable rod 4 is slidably connected to a fixed plate 5, the fixed plate 5 is set to fix the moving path of the movable rod 4, and the side of the fixed plate 5 is fixedly connected to the inner wall of the sampling tube 1.

[0027] The fixing plate 5 is fixed in the inner cavity of the sampling tube 1, and the two ends of the top of the fixing plate 5 are slidably connected to the limit rods 6 through the opened through grooves. The fixed plate 5 is set to fix the moving path of the two limit rods 6, and the bottom ends of the two limit rods 6 are fixedly connected to the sealing plate 2. The two limit rods 6 are set to prevent the movable rod 4 from rotating during the longitudinal movement, thereby improving the movement stability of the movable rod 4. The top of the limit rod 6 is fixedly connected to the limit block 7. The two limit blocks 7 are set to prevent the limit rod 6 from detaching from the fixing plate 5 during the movement, thereby improving the functional structure stability of the soil sampler. The top of the movable rod 4 is fixedly connected with a threaded block 8, and the threaded block 8 is threadedly connected with a threaded tube 9, so that the threaded block 8 can move along the threaded path of the threaded tube 9, and the side of the threaded tube 9 has an interference fit with the limit bearing 11.

[0028] The set limit bearing 11 fixes the rotation position of the threaded tube 9, and the outer ring of the limit bearing 11 is embedded and fixedly connected with the sampling tube 1, so as to facilitate the relative rotation of the threaded tube 9 and the sampling tube 1. A handle 10 is fixedly connected to the top of the threaded tube 9. The set handle 10 facilitates the rotation of the threaded tube 9, thereby improving the convenience of using the soil sampler. By extending the sampling tube 1 into the specified depth in the soil, the handle 10 is rotated, and the threaded block 8 moves along the threaded path of the threaded tube 9. During the transmission process, the sealing plate 2 is adjusted to a specified height inside the sampling tube 1. At this time, the sampling tube 1 is pushed to extend into the soil, so that the space below the sealing plate 2 inside the sampling tube 1 samples the soil at a specified depth, thereby improving the soil sampling accuracy of the soil sampler at different depths.

[0029] A sampling barrel 1 extends from the top of the threaded tube 9, and a movable ring 12 is sleeved on the outer wall of the sampling barrel 1. The inner wall of the movable ring 12 is slidably connected to the sampling barrel 1, so that the movable ring 12 can be moved along the path of the sampling barrel 1. The two ends of the inner wall of the movable ring 12 are slidably connected to the limit plates 13 through the grooves. The two limit plates 13 are fixedly connected to the sampling barrel 1 on the side. The limit plates 13 are fixed to the moving path of the movable ring 12 to prevent the movable ring 12 from rotating relative to the sampling barrel 1 during movement, thereby improving the functional structural stability of the soil sampler. The two side surfaces of the sampling barrel 1 are connected with connecting rods 17 through a plurality of grooves arranged in an array, and the end faces of the two connecting rods 17 pass through the movable ring 12.

[0030] The grooves at both ends of the side of the sampling tube 1 are located in the same horizontal plane and are plugged into two plug-in rods 17 to fix the longitudinal height of the movable ring 12.

The two screw blocks 15 are fixedly connected to the movable ring 12 on the adjacent sides. Pedals 14 are fixedly connected at both ends of the outer wall of the movable ring 12. By adjusting the height of the two pedals 14, the length of the sampling tube 1 extending into the soil is adapted to facilitate the sampling tube 1 to be stepped into the soil. A rubber plate 18 with an anti-slip effect is fixedly connected to the top of the pedal 14, and the provided rubber plate 18 provides an anti-slip effect.

[0031] The working principle, size and model are irrelevant to the function of this application, so they are not described in detail. The control method of the utility model is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0032] How it works

[0033] When using the ecological and environmentally friendly deep soil sampling device, the user moves the conical drill 3 to the position of the soil to be sampled, and provides a downward force to the sampling tube 1 by stepping on the pedal 14 during the transmission process, so that the conical drill 3 and the sampling tube 1 extend into the soil. When the soil plane moves to the position of the pedal 14, the user rotates the bolt 16 to release the threaded connection between the bolt 16 and the screw block 15, and releases the plug-in rod 17 extending into the groove on the side of the sampling tube 1. At this time, the movable ring 12 moves along the sampling tube 1 to the specified position, so that the bolt 16 is threadedly connected with the screw block 15, and the plug-in rod 17 penetrates the movable ring 12 and extends into the groove on the side of the sampling tube 1, so as to fix the position of the pedal 14, thereby facilitating stepping on the pedal 14, so that the sampling tube 1 moves to the specified depth for sampling, thereby preliminarily improving the convenience of use of the soil sampler.

[0034] The sampling tube 1 extends to the specified position of the soil, and the handle 10 is rotated to make the threaded block 8 move along the threaded path of the threaded tube 9. During the transmission process, the height of the sealing plate 2 inside the sampling tube 1 is adjusted to release the sealing and shielding effect of the sealing plate 2 on the sampling tube 1. At the same time, the pedal 14 is stepped on to achieve soil sampling, which is convenient for sampling soil at a specified depth. The two limit rods 6 are moved along the through groove opened at the top of the fixed plate 5 to prevent the sealing plate 2 and the movable rod 4 from rotating during the movement, thereby improving the movement stability of the threaded block 8 along the threaded path of the threaded tube 9. The limit block 7 is set to prevent the limit rod 6 from detaching from the fixed plate 5 during the movement, thereby improving the functional structural stability of the soil sampler.
