[0041] Telescopic rod 24 is inserted into the inside of support rod 22 from the bottom surface of support rod 22, and the height of support mechanism 2 is adjusted by locking telescopic rod 24 in the required position through the extrusion and contact of locking buckle 23 and the side wall of telescopic rod 24, needle seat 25 is used for finally contacting with the ground, provides the stable support point, and the whole device is stably supported on the ground, when the support height needs to be adjusted, locking buckle 23 is loosened first, telescopic rod 24 is slid freely in support rod 22, telescopic rod 24 is adjusted to the appropriate position, and then is fixed through locking buckle 23, and the height adjustment of support mechanism 2 is completed.

[0043] The bottom surface of mounting seat 1 is fixedly connected with mounting cylinder 3, the bottom surface of mounting cylinder 3 is fixedly installed with mounting bin 4 through screw, mounting bin 4 is used as a structure for containing and installing other components, one side of mounting bin 4 is rotatably connected with hand wheel 5 through bearing, the side wall of the rotating rod 51 of hand wheel 5 is key-connected with first transmission mechanism 6, when rotating hand wheel 5, rotating rod 51 rotates, and the rotating torque is transmitted to first transmission mechanism 6 due to the transmission effect of key connection, and the bottom side wall of first transmission mechanism 6 is threadedly connected with one end of moving mechanism 7;

[0044] The first transmission mechanism 6 comprises a first bevel gear 61, a second bevel gear 62, a limiting frame 63 and a lead screw 64. The side wall of the first bevel gear 61 is in meshing connection with the second bevel gear 62. The side wall of the rotating rod 51 of the hand wheel 5 is in key connection with the inside of the first bevel gear 61. The inside of the second bevel gear 62 is in key connection with the top end of the lead screw 64. The side wall of the lead screw 64 is in screw connection with the moving mechanism 7. The two ends of the limiting frame 63 are in rotating connection with the side wall of the rotating rod 51. The bottom of the limiting frame 63 is in rotating connection with the side wall of the lead screw 64.

[0045] The side wall of the first bevel gear 61 is in meshing connection with the second bevel gear 62, so as to realize the transmission of power and the transformation of speed and torque. The rotating rod 51 of the hand wheel 5 drives the first bevel gear 61 to rotate, so that the second bevel gear 62 rotates. The inside of the second bevel gear 62 is in key connection with the top end of the lead screw 64, so as to transmit the rotary motion to the lead screw 64. Meanwhile, the two ends of the limiting frame 63 are in rotating connection with the side wall of the rotating rod 51, and the bottom is in rotating connection with the side wall of the lead screw 64. The limiting frame 63 plays a role in limiting and supporting the lead screw 64 and the rotating rod 51, so as to ensure the stability of the lead screw 64 and the rotating rod 51 during rotation, and prevent the lead screw 64 and the rotating rod 51 from deviating or shaking due to force. When the second bevel gear 62 rotates, the lead screw 64 rotates. The rotary motion of the lead screw 64 is the key to driving the subsequent moving mechanism 7 to move.

[0046] The main role of the first transmission mechanism 6 is to convert the rotation of the hand wheel 5 into the rotation of the lead screw 64, change the transmission ratio through the meshing of the bevel gears, and ensure the stability during transmission by using the limiting frame 63, so as to provide reliable power transmission and support for the movement of the subsequent moving mechanism 7.

The other end of the connecting plate 72 is fixedly connected with the side wall of the limiting ring 73. The limiting ring 73 is in rotating connection with the side wall of the sampling mechanism 9.

[0048] When the lead screw 64 rotates under the drive of the first transmission mechanism 6, the internal thread cylinder 71 will move axially along the lead screw 64 due to the screw connection. One end of the connecting plate 72 is fixedly connected with the side wall of the internal thread cylinder 71, and the other end is fixedly connected with the side wall of the limiting ring 73. Therefore, the movement of the internal thread cylinder 71 will drive the connecting plate 72 and the limiting ring 73 to move together. Due to the screw connection between the internal thread cylinder 71 and the lead screw 64, the internal thread cylinder 71 will realize linear motion by rotating the lead screw 64, thereby driving the connecting plate 72 and the limiting ring 73 connected thereto to displace correspondingly. The rotary motion of the lead screw 64 is converted into linear motion, so as to realize the up-down movement of part of the components in the device. Meanwhile, the limiting ring 73 will be connected and interacted with the sampling mechanism 9 subsequently. Through the linear motion of the moving mechanism 7, the position of the sampling mechanism 9 can be adjusted, so as to prepare the position for soil sampling operation.

[0050] When the rotating rod 51 rotates, the third bevel gear 81 rotates to drive the fourth bevel gear 83 meshingly connected therewith to rotate, and the driving rod 82 rotates accordingly, the driving rod 82 is rotatably connected in the box body 85 through a bearing to ensure the smoothness of rotation, and the bottom end of the driving rod 82 is fixedly connected with the top end of the hexagonal column 84 to transmit the rotating motion to the hexagonal column 84 and provide a power source for the subsequent rotating action of the sampling mechanism 9.

[0052] When the hexagonal column 84 rotates, the sampling rod 91 will rotate together due to the cooperation of the hexagonal groove 92 and the hexagonal column 84, when the sampling rod 91 rotates, the spiral blade 94 rotates accordingly, and the soil is cut into and upwardly conveyed by the spiral structure of the spiral blade 94, and the spiral gap of the spiral blade 94 on the bottom end of the sampling rod 91 is smaller than the spiral interval on the bottom side wall of the sampling rod 91, so that the soil is more easily cut into and upwardly pushed from the bottom of the spiral blade 94 during sampling, and the efficiency and effect of sampling are improved.

[0053] Meanwhile, in order to be able to call the up and down movement of the sampling rod 91, through the limiting ring 73 in the movement of the movement mechanism 7 and is limited by the limiting disc 93, so that the sampling rod 91 can be driven to move up and down, so that the sampling rod 91 moves downward, and the helical blade 94 is convenient for taking out the corresponding position of the soil.
