[0023] As shown in Figures 1 and 2, a soil extraction device includes an insert 3, the insert 3 includes a cylinder 4 and a plug at the lower end of the cylinder 4, a plurality of sampling members 5 are arranged on the cylinder 4 at equal intervals in the vertical direction, the sampling member 5 includes a sampling groove 23 opened on the side wall of the cylinder 4, and a protruding baffle 6 is provided on the upper part of the sampling groove 23. The protruding baffle 6 is connected to the side wall of the sampling groove 23 through a first moving member 20. The first moving member 20 is used to control the protruding baffle 6 to extend out of the sampling groove 23. The inner side of the sampling groove 23 A switch component for opening and closing the sampling groove 23 is provided at the lower part of the wall, and a second movable member 21 is provided on the upper part of the switch component. The second movable member 21 is connected to the extending scraper 7. The second movable member 21 is used to control the extending scraper 7 to extend out of the sampling groove 23. A sampling plate 9 is provided in the sampling groove 23 and is located below the extending baffle 6. The sampling plate 9 is connected to the side wall of the sampling groove 23 through a third movable member 22. The third movable member 22 is used to control the sampling plate 9 to extend out of the sampling groove 23 to sample the soil.

[0024] When it is necessary to sample the soil, the insert 3 is inserted into the soil to be sampled, the first movable member 20 controls the extending baffle 6 to extend out of the sampling groove 23 and to contact the end of the extending baffle 6 with the side wall of the soil. The extending baffle 6 is convenient for preventing the soil above the extending baffle 6 from falling into the sampling groove 23, and then the second movable member 21 controls the extending scraper 7 to extend out of the sampling groove 23 and contact the side wall of the soil. The switch opens the opening of the sampling groove 23 and moves the extending scraper 7 downward so that the extending scraper 7 scrapes the soil. Then, the third movable member 22 controls the sampling plate 9 to extend out of the sampling groove 23 to sample the scraped soil. In this way, it is not easy to sample soil that does not belong to the depth, thereby improving the accuracy of sampling. After the sampling plate 9 samples the soil, the third movable member 22 controls the sampling plate 9 to move to the sampling groove 23 and reset. The first movable member 20 and the second movable member 21 respectively control the extending baffle 6 and the extending scraper 7 to reset, and the switch opens and closes the opening of the sampling groove 23.

[0025] The upper end surface of the extended scraper 7 is set at an angle, and the height of one end of the upper end surface of the extended scraper 7 connected to the second movable member 21 is higher than the other end thereof, thereby reducing the probability of soil falling from the extended scraper 7 entering the sampling trough 23, and the soil on the extended scraper 7 can roll down along its inclined surface.

[0026] The switch component includes a receiving groove opened at the lower part of the inner wall of the sampling groove 23, and a gate-controlled movable member 24 is provided at the bottom of the receiving groove. The gate-controlled movable member 24 is connected to the movable plate 8, and the gate-controlled movable member 24 is used to move the movable plate 8 to the opening of the sampling groove 23 to close it.

[0027] The other end of the sampling plate 9 is connected to a swing plate 11 through a hinge shaft 10. The hinge shaft 10 is connected to a swing motor fixedly connected to the sampling plate 9. The side wall of the hinge shaft 10 is fixedly connected to the swing plate 11. When the swing motor is started, it drives the swing plate 11 to swing upward in a clockwise direction. The second moving member 21 controls the sampling plate 9 to extend out of the sampling groove 23. The swing plate 11 contacts the soil. At this time, the swing motor is started, driving the swing plate 11 to swing downward in a counterclockwise direction. The swing plate 11 further scrapes the soil. After the swing plate 11 swings a certain angle, the second moving member 21 controls the swing plate 11 to extend into the soil. At this time, the swing motor is started, driving the swing plate 11 to swing upward in a clockwise direction, collecting the soil on the swing plate 11 and the sampling plate 9. Then the second moving member 21 controls the swing plate 11 and the sampling plate 9 to reset back to the sampling groove 23.

[0028] Elastic rubber pads 12 are provided on the upper and lower sides of the hinge shaft 10. The two ends of the elastic rubber pad 12 are respectively connected to the sampling plate 9 and the swing plate 11. The setting of the elastic rubber pad 12 is convenient for preventing the soil from contacting the hinge shaft 10, thereby affecting the rotation of the hinge shaft 10 and reducing the sampling efficiency.

[0029] As shown in Figures 3 and 4, a pushing piece and a storage box 13 are provided in the sampling groove 23. The pushing piece and the storage box 13 are located on both sides of the sampling plate 9. A feeding port is provided on the side of the storage box 13 facing the pushing piece. The pushing piece includes a pushing movable piece 19 connected to the inner side wall of the sampling groove 23. The other end of the pushing movable piece 19 is connected to a pushing plate 18. The pushing movable piece 19 controls the movement of the pushing plate 18 to push the soil on the sampling plate 9 into the storage box 13.

[0030] The pushing plate 18 is arranged at an angle, and a horizontally arranged limiting slide is provided at the upper end of the pushing plate 18. The distance between the upper end of the pushing plate 18 and the feeding port is smaller than the distance between the lower end of the pushing plate 18 and the feeding port. The upper end of the pushing plate 18 is arranged below the top of the feeding port. The upper end of the feeding port is hinged with a hinged door 14, and one side of the hinged door 14 is connected to the inner wall of the storage box 13 by an elastic spring 16. During the movement of the pushing plate 18, the upper end of the pushing plate 18 first contacts the hinged door 14 to open the feeding port, so as to facilitate pushing the soil pushed by the pushing plate 18 into the storage box 13. In addition, the other side of the hinged door 14 is provided with a limiting plate 17 connected to the outer wall of the storage box 13. When the hinged door completely blocks the feeding port, the limiting plate 17 is arranged in contact with the hinged door.

[0031] A plurality of protrusions 15 are arranged at equal intervals on the side where the hinged door and the push plate 18 are arranged facing each other. When the push plate 18 moves the hinged door, the push plate 18 contacts the plurality of protrusions 15 on the hinged door in sequence from top to bottom, thereby driving the hinged door and the push plate 18 to shake, so as to shake off the soil adhering to the push plate 18 and speed up the efficiency of the soil pushed by the push plate 18 into the storage box 13.

[0032] As shown in Figure 1, the two storage boxes 13 arranged adjacent to each other are fixedly connected or detachably connected, and a handle is connected to the upper end of the uppermost storage box 13, and the handle extends out of the cylinder 4. A placement slot for accommodating the storage box 13 is provided on the cylinder 4. When the storage box 13 needs to be taken out, all the storage boxes 13 can be taken out of the placement slot by using the handle, which is convenient for testing the storage box 13 and cleaning the storage box 13.

[0033] As shown in Figure 1, the insert 3 is connected to the support frame 1 through the lifting member 2. The lifting member 2 is used to adjust the distance between the insert 3 and the support frame 1. The support frame 1 can be fixed on the ground. The distance between the insert 3 and the support frame 1 is adjusted by the lifting member 2, and then the insert 3 is inserted into the soil.

[0034] The lifting member 2 is used to adjust the distance between the insert 3 and the support frame 1. The lifting member 2 can be a first lifting telescopic rod, which can be driven by hydraulic, electric or other driving methods.

[0035] The door control moving member 24 , the first moving member 20 , the second moving member 21 and the third moving member 22 may all be driving telescopic rods, and the driving telescopic rods may be driven by hydraulic, electric or other driving methods.
