[0076] The operation of the lifting mechanism 8 is as follows: the first screw 802 is driven to rotate by the second motor 805, and the first screw 802 and the first nut 803 are threaded together, and the guiding effect of the guide bar 804 and the guide groove 8011 is cooperated to drive the first nut 803, the guide bar 804 and the movable disk 9 to move up and down together, and the drill rod 7 will move with the movable disk 9 to achieve the adjustment of the up and down position, so that the drill rod 7 can be inserted into the soil layer or leave the soil layer.

[0077] like Figure 2-5 as well as Fig. 9As shown, the pressing mechanism 12 includes a second screw rod 1201, a second nut 1202, a pressure plate 1203, a guide portion movable left and right, a pressure strip 1208 and a second spring 1209; one end of the second screw rod 1201 is fixedly connected to the output shaft end of the first motor 2, the second nut 1202 is threadedly connected to the second screw rod 1201, a middle hole is provided in the middle of the pressure plate 1203, the second nut 1202 is fixedly engaged in the middle hole on the pressure plate 1203, a side of the pressure plate 1203 is provided with an embedding groove 12031, and the embedding groove 12031 is connected to the guide portion, The pressure strip 1208 is cooperatively connected with the vertical groove 102 opened in the wall of the protective tube 1, and the vertical groove 102 is connected with the bottom circular groove 101, the bottom end of the pressure strip 1208 is fixedly connected to the top of the insertion tube 11, the top end of the pressure strip 1208 is bent 90° toward the axial direction of the protective tube 1, and the bent portion of the pressure strip 1208 is slidingly connected with the side groove 103 opened on the inner wall of the protective tube 1, and the side groove 103 is connected with the vertical groove 102, the top of the pressure strip 1208 is elastically connected to the top end surface of the vertical groove 102 by the second spring 1209, and the bent portion of the pressure strip 1208 is in contact with the bottom surface of the pressure plate 1203.

[0078] The guide portion includes a guide rod 1204, a positioning column 1205 and a first spring 1206; the guide rod 1204 passes through the embedding groove 12031, and at least one positioning column 1205 is fixedly connected to one side of the guide rod 1204, the positioning column 1205 is matched and connected with a positioning hole 1207 opened on the inner wall of the protective tube 1, the first spring 1206 is sleeved on the positioning column 1205, and the guide rod 1204 is elastically connected to the inner wall of the protective tube 1 through the first spring 1206.

[0079] The bottom end of the guide rod 1204 is fixedly connected with a second permanent magnet 15 , the second permanent magnet 15 is magnetically connected with a first permanent magnet 14 , the first permanent magnet 14 is fixedly connected with a support frame 13 , and the support frame 13 is fixedly connected to the top surface of the movable disk 9 .

[0080] In the initial state of the entire drilling rig, the position of the movable plate 9 is as follows Figure 4 As shown, it is in the highest position, the drill rod 7 is received in the protective tube 1, wherein the first permanent magnet 14 and the second permanent magnet 15 are in contact with each other, the two are magnetically attracted together, and the first spring 1206 is in a stretched state, and the guide rod 1204 passes through the embedding groove 12031.

[0081] When in use as a whole, the bottom end of the protective tube 1 is placed on the soil layer, and then the first motor 2 is started. The first motor 2 drives the second screw 1201 to rotate forward, and the second screw 1201 and the second nut 1202 are threaded, and the guiding effect provided by the guide rod 1204 and the embedded groove 12031 makes the second nut 1202 and the pressure plate 1203 move downward together, and the pressure plate 1203 pushes the bent part of the pressure strip 1208 downward, and the pressure strip 1208 is guided by the vertical groove 102 and moves downward, thereby pushing the insertion tube 11 to move downward, so that the insertion tube 11 is inserted into the soil layer, and at the same time the pressure strip 1208 stretches the second spring 1209.

[0082] After the above operations, the protective tube 1 is connected to the soil layer, especially the insertion tube 11 is inserted into the soil layer to avoid pits and there is a gap between the protective tubes 1.

[0083] Then, turn off the first motor 2, and then drive the movable disk 9 downward through the lifting mechanism 8. The movable disk 9 drives the first permanent magnet 14 downward through the support frame 13. The first permanent magnet 14 is separated from the second permanent magnet 15, and the two lose magnetic attraction. At this time, the drill rod 7 is still in the protective tube 1, and then start the first motor 2.

[0084] After the above operation, the second permanent magnet 15 loses the magnetic attraction of the first permanent magnet 14, and pulls the guide rod 1204 through the elastic force of the first spring 1206, so that the guide rod 1204 is separated from the embedded groove 12031, so that when the first motor 2 drives the second screw rod 1201 to rotate, the nut and the pressure plate 1203 rotate together, and the pressure plate 1203 does not move up and down. The driving connection between the first motor 2 and the pressing mechanism 12 is released, and the height position of the pressure plate 1203 remains unchanged, and the pressing state of the pressure strip 1208 is always maintained.

[0085] Subsequently, the first motor 2 drives the drill rod 7 to rotate, and the lifting mechanism 8 drives the drill rod 7 downward, so that the drill rod 7 drills into the soil layer. After drilling, the lifting mechanism 8 drives the drill rod 7 upward, so that the drill rod 7 leaves the soil layer, until the first permanent magnet 14 is aligned with the second permanent magnet 15, so that the first permanent magnet 14 provides magnetic attraction for the second permanent magnet 15. When the guide rod 1204 is aligned with the embedded groove 12031, the guide rod 1204 directly enters the embedded groove 12031. When the guide rod 1204 is not aligned with the embedded groove 12031, the guide rod 1204 is pressed on the circumferential surface of the pressure plate 1203 by the action of magnetic attraction, and the first motor 2 drives the pressure plate 1203. After 203 is reversed to align the embedding groove 12031 with the guide rod 1204, the guide rod 1204 enters the embedding groove 12031, and at the same time the guide rod 1204 stretches the first spring 1206 to generate a stretching elastic force, and then the first motor 2 is driven in the reverse direction, in conjunction with the guidance of the guide rod 1204 and the embedding groove 12031, so that the pressure plate 1203 is reset upward, the pressure rod loses the downward pressure, and the elastic force of the second spring 1209 drives the pressure rod and the insert cylinder 11 to reset, and the insert cylinder 11 is pulled out of the soil layer, and then the first motor 2 is turned off.

[0086] Through the above design, the pressing mechanism 12 and the rotation drive of the drill rod 7 share the drive of the first motor 2, and both use one power source. The left and right movement of the guide part in the pressing mechanism 12 is used to establish or disconnect the connection with the first motor 2, so that the pressing mechanism 12 is disconnected during the process of the drill rod 7 drilling into or leaving the soil layer. The pressing mechanism 12 will not affect the drive of the drill rod 7 by the first motor 2.

[0087] Furthermore, the left and right driving of the guide part is achieved by the movable disk 9 driving the first permanent magnet 14 to leave the second permanent magnet 15 and reset, so that the left and right movement of the guide part does not require additional power source and manual operation.

[0088] When implemented, a ball structure can be provided on the top surface of the bent portion of the pressure rod, and the ball can fit with the bottom surface of the pressure plate 1203 to ensure rolling friction when the pressure plate 1203 rotates, thereby reducing wear.
