The specific working procedure is as follows:
according to the soil sampling state of the sampling device, the invention makes the distinction between before sampling, during sampling and after sampling, and makes the following detailed explanation according to the distinction:
First, before sampling:
Firstly, checking each part of the sampling device, then moving the sampling device to a position where soil sampling is required, as the first magnet 67 on the cam 6 is magnetically attracted with the corresponding second magnet 13 on the inner wall of the sampling tube 1, the side wall of the cam 6 away from the movable hole 64 is far away from the corresponding sampling groove 12, namely, the position of the sliding block 62 on the sliding rail 61 is limited and close to the movable hole 64, the sliding block 62 drives the push disc 8 to be limited and close to the movable hole 64 through the connecting rod 63, the push disc 8 drives the tension spring 81 and the corresponding sampling cover 4 to be positioned in the corresponding sampling groove 12, meanwhile, the annular groove 41 on the sampling cover 4 is communicated with the position of the strip-shaped groove 21 and corresponds to the position of the sampling cover 4 away from the center rod 5, the end of the sampling cover 4 is matched with the outer wall of the sampling tube 1, then one foot is trampled on the trample plate 92, and the limiting hole 91 on the strip-shaped plate 9 is driven to be staggered with the sampling groove 12 after trampling, so that the strip-shaped plate 9 is clamped into the annular groove 41 on the outer wall of the sampling cover 4, and the axial direction of the sampling cover 4 is locked;
Then, pressing the T-shaped rod 71 to drive the center rod 72 and the triangular bar 7 to synchronously move, the triangular bar 7 enters the corresponding triangular groove 51 under the guide of the guide surface 73 at the end part, along with the continuous pressing of the T-shaped rod 71, the T-shaped rod 71 drives the triangular bar 7 to be inserted into the triangular groove 51 in the center rod 5 at the lower position, the lower end of the T-shaped rod 71 pushes the plurality of center rods 5 to approach each other after moving along the center hole 32, the plurality of center rods 5 drive the adjacent two baffle rings 52 to approach each other in the process of approaching each other, the first spring 53 is compressed in the process of approaching the adjacent two baffle rings 52, one end of the adjacent two center rods 5 is fixedly connected with the mutually meshed teeth 54, so that the adjacent two center rods 5 are meshed through the teeth 54 after approaching under the extrusion of the T-shaped rod 71, the contact of the adjacent center rods 5 is realized, and the circumferential locking is finished, then the T-shaped rod 71 is rotated to drive the center rod 72 and the triangular strip 7 to rotate, the triangular strip 7 is rotated to drive the corresponding center rod 5 to rotate, one center rod 5 is rotated to drive the plurality of center rods 5 to synchronously rotate, the center rods 5 are axially and slidingly connected in the movable holes 64 of the cams 6, the corresponding cams 6 are driven to rotate during the rotation of the plurality of center rods 5, the supporting blocks 65 play a supporting role on the cams 6, the sliding blocks 62 are extruded away from the corresponding movable holes 64 through the cooperation of the sliding rails 61 and the sliding blocks 62 during the rotation of the cams 6, so that the sliding blocks 62 move to the position of the corresponding sliding rails 61, which is far away from the movable holes 64, the sliding blocks 62 drive the connecting rods 63 and the pushing discs 8 to be far from the corresponding movable holes 64, the axial movement of the sampling cover 4 is locked, but the circumferential movement is not locked, so in the process that the connecting rod 63 is far away from the corresponding movable hole 64, the connecting rod 63 drives the sampling cover 4 to rotate in the sampling groove 12 through spiral transmission, and the pushing disc 8 is far away from the corresponding inner bottom wall of the sampling cover 4, so that when the tension spring 81 is pulled, the pushing disc 8 pushes out the residual soil and other foreign matters in the sampling cover 4, after one end of the pushing disc 8 far away from the connecting rod 63 moves to the opening position of the sampling cover 4, one end of the sampling cover 4 far away from the connecting rod 63 is adapted to the outer wall of the sampling tube 1 again after rotating, and meanwhile, one surface of the pushing disc 8 far away from the connecting rod 63 is adapted to one end of the sampling cover 4, so that the outer wall of the sampling tube 1 forms a complete curved surface, the resistance of the sampling tube 1 entering the soil is reduced, and the preparation work of the sampling device is finished;
second, in the sampling:
On the basis that the T-shaped rod 71 and the central hole 32 do not rotate relatively, the adjacent central rod 5 is meshed and contacted, and the pedal 92 is stepped on, the handle 31 is held to drive the sampling rod 3, the sampling tube 1 and the drill bit 11 to rotate, so that the drill bit 11 is utilized to break open the floating soil and weeds into the soil, the sampling cover 4 can also move into the soil along with the entering of the sampling tube 1, and then soil sampling is carried out according to sampling requirements, wherein the soil sampling is divided into three types:
