The positioning rod 809 is slidably connected to the gantry 1, and a sampling device is set. The sampling device can be effectively fixed by utilizing the cooperation between the connecting plate 801, the fixing block 802, the connecting frame 803, the fixing rod 804, the long plate 805 and the positioning column 806, which can ensure that it remains stable during the sampling process and avoids the sampling position deviation or inaccurate depth caused by shaking or movement, thereby significantly improving the accuracy of sampling. In addition, the fixed sampling device can also effectively reduce the risk of the sampling device falling off or tilting, further improving the safety level of the operation. One end of the limiting rod 809 is rotatably connected with a ball 810. The upper surface of the long board 805 is glued with a plurality of anti-skid strips 808, and the anti-skid strips 808 are made of rubber. The ball 810 slides along the surface of the gantry 1, and the ball 810 reduces the friction between the limit rod 809 and the gantry 1, so that the long board 805 can be pressed down more conveniently and smoothly. The anti-skid strip 808 can facilitate the staff to press the long board 805 and increase the friction. The arc surface of the limit rod 809 is covered with a spring 811, and the two ends of the spring 811 are fixedly connected to the limit rod 809 and the connecting frame 803 respectively. When the ball 810 contacts another circular hole opened on the surface of the gantry 1, At this time, the spring 811 begins to use its own elastic force to drive the limit rod 809 to slide and insert into the gantry 1.

A plurality of spurs 807 are fixedly connected to the surface of the positioning column 806. The positioning column 806 will also drive the spurs 807 to be inserted into the ground. The spurs 807 can effectively prevent the positioning column 806 from sliding upward when inserted into the ground, thereby improving the stability of the sampling equipment.

[0033] Reference Figure 5 and Figure 6As shown, specifically, the replacement device 9 includes three screw rods 91, and the three screw rods 91 are all threadedly connected to the drill bit 6. The surface of the spiral rotating rod 7 is provided with three circular grooves 95, and the three screw rods 91 are all slidably connected to the inner wall of the circular groove 95. The surface of the spiral rotating rod 7 is fixedly connected with a clamping block 92, and the surface of the drill bit 6 is provided with a clamping groove 94. The size of the clamping block 92 is adapted to the clamping groove 94, and the clamping block 92 is slidably connected to the clamping groove 94. By setting the replacement device 9, the replacement device 9 can regularly replace the drill bit 6 by utilizing the mutual cooperation between the screw rods 91, the clamping block 92, the clamping groove 94 and the circular groove 95, thereby effectively reducing the wear of the drill bit 6, extending the service life of the drill bit 6, and reducing the maintenance cost. At the same time, timely replacement of the drill bit 6 can keep the drill bit 6 in a good state, ensuring that the drill bit 6 is in a good condition during the drilling process The stability and accuracy of drilling can be improved, thereby improving the quality and reliability of drilling. A flexible pad 93 is glued to one end of the screw rod 91, and the flexible pad 93 is made of rubber. The screw rod 91 will drive the flexible pad 93 to move, so that the flexible pad 93 abuts against the inner wall of the circular groove 95. The flexible pad 93 can protect the circular groove 95 to prevent the screw rod 91 from abutting against the circular groove 95 with too much force, thereby causing damage and wear to the circular groove 95, thereby protecting the spiral rotating rod 7. The surfaces of the block 92 and the slot 94 are both provided with an inclined surface 96, and the inclined surface 96 facilitates docking and installation, thereby avoiding the situation where the spiral rotating rod 7 and the drill bit 6 have a high degree of adaptability and are difficult to align and install. The block 92 and the slot 94 facilitate the alignment of the screw rod 91 with the circular groove 95, thereby improving the efficiency of installing the drill bit 6.

[0034] Working principle: When using the sampling device, the supporting device 8 is needed to fix the sampling device. First, pull the limit rod 809, and the limit rod 809 slides along the surface of the connecting frame 803. The limit rod 809 will drive the ball 810 to move, so that the limit rod 809 is out of contact with the gantry 1. At this time, the limit rod 809 will stretch the spring 811, and then press the long board 805 toward the bottom plate 2. A number of anti-slip strips 808 are placed on the surface of the long board 805. The anti-slip strips 808 can facilitate the staff to press the long board 805. By increasing the friction force, the long board 805 will drive the fixing rod 804 to move, and the fixing rod 804 will drive the connecting frame 803 to slide along the surface of the fixing block 802. The long board 805 will drive the positioning movement while moving, until the positioning column 806 is inserted into the ground. When the ball 810 contacts another circular hole on the surface of the gantry 1, the spring 811 begins to drive the limiting rod 809 to slide and insert into the gantry 1 with its own elastic force. The spring 811 achieves the effect of automatically resetting the limiting rod 809, and the spring 811 can also The position of the limit rod 809 is limited to prevent the limit rod 809 from being lost due to loss of contact with the connecting frame 803. The ball 810 slides along the surface of the gantry 1 to reduce the friction between the limit rod 809 and the gantry 1, thereby pressing down the long board 805 more conveniently and smoothly. The positioning column 806 is inserted into the ground, and the positioning column 806 also drives the spur 807 to be inserted into the ground. The spur 807 can effectively prevent the positioning column 806 from sliding upward when inserted into the ground, thereby The stability of the sampling equipment is improved by setting up a sampling device. By utilizing the cooperation between the connecting plate 801, the fixing block 802, the connecting frame 803, the fixing rod 804, the long plate 805 and the positioning column 806, the sampling device can be effectively fixed to ensure stability during the sampling process and avoid shaking or movement that may cause sampling position deviation or inaccurate depth, thereby significantly improving the accuracy of sampling. In addition, fixing the sampling device can also effectively reduce the risk of the sampling device falling off or tilting, further improving the safety level of the operation.

[0035] When the drill bit 6 is used for drilling the ground for a long time, the drill bit 6 is prone to damage and wear, and the drill bit 6 needs to be replaced regularly. First, the screw rod 91 is rotated, and the screw rod 91 moves with the help of the thread in the drill bit 6 until the screw rod 91 is out of contact with the drill bit 6. At this time, the drill bit 6 is out of contact with the spiral rotating rod 7, and the removal of the drill bit 6 is completed. Then, the card groove 94 on the drill bit 6 is aligned with the card block 92 of the spiral rotating rod 7 and slidably installed. The inclined surface 96 facilitates the docking installation and avoids the situation where the spiral rotating rod 7 and the drill bit 6 have a high degree of adaptability and are difficult to align and install. The card block 92 and the card groove 94 facilitate the alignment of the screw rod 91 with the circular groove 95, thereby improving the efficiency of installing the drill bit 6. Then, the screw 91 is rotated again, and the screw 91 The flexible pad 93 will be driven to move, so that the flexible pad 93 is pressed against the inner wall of the circular groove 95. The flexible pad 93 can protect the circular groove 95, and prevent the screw rod 91 from pressing against the circular groove 95 with too much force, thereby causing damage and wear to the circular groove 95. The spiral rotating rod 7 can be protected and the service life can be extended. By setting up a replacement device 9 and utilizing the mutual cooperation among the screw rod 91, the block 92, the card groove 94 and the circular groove 95, the replacement device 9 can regularly replace the drill bit 6, thereby effectively reducing the wear of the drill bit 6, extending the service life of the drill bit 6, and reducing the maintenance cost. At the same time, timely replacement of the drill bit 6 can keep the drill bit 6 in a good state, ensure the stability and accuracy of the drill bit 6 during the drilling process, and thus improve the quality and reliability of drilling.
