[0030] Preferably, four movable grooves are equidistantly opened around the bottom of the annular plate 3, and a movable block 4 is arranged in the movable groove. A translation component for driving the movable block 4 to move along the movable groove is provided on the annular plate 3, and the bottom of the movable block 4 is fixedly connected to an arc plate 6 through a connecting rod 5, and a pointed cone end is provided at the bottom of the arc plate 6.

[0031] In the above technical scheme, when in use, the bracket 1 is placed on the surface of the soil, and the annular frame 2 is driven to descend by the driving component, thereby bringing the annular plate 3, the mounting frame 32, the moving block 4, the connecting rod 5, and the curved plate 6 down, and at the same time, the rotating component is cooperated to drive the annular plate 3 to rotate, so that the moving block 4, the connecting rod 5 and the curved plate 6 rotate, so that the pointed cone columnar component composed of four curved plates 6 drills into the soil. After the drilling is completed, the driving component and the rotating component are stopped. At this time, the top of the curved plate 6 is located on the surface of the soil, and then the sampling plate 7 is driven by the pushing component to move in the direction away from the cavity. At the same time, the movable plate 8 compresses the first spring 9 to deform it to generate a force, so that the sampling port on the sampling plate 7 is located in the soil, and then the rotation of the curved plate 6 and the driving sampling plate 7 is realized through the continued driving of the rotating component, so that soil of different layers is collected into the sampling port. After that, the rotating assembly is stopped and the pushing of the pushing assembly is cancelled. At this time, the first spring 9 releases the force to reset the movable plate 8 and the sampling plate 7. The annular frame 2 is driven to rise and reset through the driving assembly, so that the arc plate 6 is taken away from the soil. The sampling plate 7 can be pushed out by the pushing assembly again, and the internal soil can be taken out to realize drilling sampling of soil at different levels. When stones in the soil block the movement of the arc plate 6 during the process of the arc plate 6 drilling into the soil, the rotating assembly and the driving assembly are stopped at this time. At this time, the four moving blocks 4 are driven to move away from each other through the translation assembly, so that the connecting rod 5 and the arc plate 6 move therewith, so that the four arc plates 6 are separated, and then the rotating assembly and the driving assembly are started again to realize the rotation and descent of the arc plate 6, so that it can avoid the stones and continue to descend to the required depth, thereby realizing the avoidance of the stones and ensuring smooth sampling.

[0032] like Figures 2 to 6As shown, the pushing assembly includes a stop block 10 fixedly mounted on the inner side of the sampling plate 7, a vertical plate 11 is slidably arranged in the cavity, a squeezing block 12 cooperating with the stop block 10 is arranged on the side of the vertical plate 11 close to the stop block 10, and a slope is arranged on the side of the squeezing block 12 close to the stop block 10, a second spring 13 is fixedly mounted on the bottom wall of the cavity, the top of the second spring 13 is fixedly connected to the vertical plate 11, a push rod 14 is threadedly connected to the top of the arc plate 6, the bottom end of the push rod 14 extends into the cavity and contacts the vertical plate 11, and a knob 15 is arranged on the top of the push rod 14. The knob 15 is turned forward to move it with the push rod 14 down to press against the vertical plate 11 and the squeezing block 12, and the squeezing block 12 cooperates with the inclined surface to squeeze the abutment block 10 and the sampling plate 7, so that the movable plate 8 moves accordingly to compress the first spring 9 to deform it and generate a force, so that the sampling plate 7 moves away from the cavity, thereby driving the sampling plate 7. At the same time, the vertical plate 11 squeezes the second spring 13 to deform it and generate a force. Conversely, the knob 15 is reversed to make the push rod 14 rise, and the second spring 13 releases its force to move the vertical plate 11 and the squeezing block 12 up, and the first spring 9 releases its force to reset the movable plate 8 and the sampling plate 7.

[0033] like Figure 4 As shown, the translation assembly includes a screw rod 16 rotatably installed in a moving groove, the moving block 4 is threadedly sleeved outside the screw rod 16, a mounting cavity is provided in the middle of the ring plate 3, one end of the screw rod 16 extends to the mounting cavity and a first bevel gear 17 is fixedly installed therein, a second bevel gear 18 meshing with a plurality of first bevel gears 17 is provided inside the mounting cavity, a first motor 19 is fixedly installed in the middle of the top end of the ring plate 3, and the output shaft of the first motor 19 is fixedly connected to the second bevel gear 18. Starting the first motor 19 causes its output shaft to rotate forwardly with the second bevel gear 18, thereby driving the first bevel gear 17 and the screw rod 16 to rotate, so that the moving block 4 is moved, so that the four moving blocks 4 move away from each other, and vice versa, starting the first motor 19 causes its output shaft to reverse, so that the movement reset of the four moving blocks 4 approaching each other can be realized.

[0034] like Figures 2 to 4 As shown, the rotating assembly includes a connecting shell 20 fixedly connected to the top of the ring plate 3 and located outside the first motor 19, and the top of the mounting frame 32 is fixedly connected to the second motor 21 through a pair of pads, and the output shaft of the second motor 21 is fixedly connected to the middle of the top of the connecting shell 20. The second motor 21 is started so that its output shaft rotates with the connecting shell 20 and the ring plate 3, thereby driving the ring plate 3.

[0035] like Figure 1As shown, the driving assembly includes a screw 22 rotatably mounted in a slide slot, both ends of the annular frame 2 are threadedly sleeved outside the screw 22, and a third motor 23 is symmetrically fixedly mounted on the top of the bracket 1, and the bottom end of the output shaft of the third motor 23 is fixedly connected to the top end of the adjacent screw 22. The third motor 23 is started to rotate its output shaft forward to drive the screw 22 to rotate, so that the annular frame 2 is driven to descend, and vice versa, the output shaft of the third motor 23 is reversed to achieve the rise of the annular frame 2.

[0036] like Figures 2 to 7 As shown, a cover body 24 is fixedly installed in the middle of the top of the mounting frame 32, an air hole is opened in the middle of the top of the cover body 24, a plunger 25 is connected to the inner thread of the air hole, an annular shell 26 is fixedly installed on the top of the ring plate 3, an annular groove matching the annular shell 26 is opened at the bottom of the mounting frame 32, an arc-shaped opening connected with the cover body 24 is opened on the top wall of the annular groove, the top of the annular shell 26 extends into the annular groove, a plurality of air inlets 27 connected thereto are provided on the top of the annular shell 26, an annular cavity is opened inside the moving block 4, the bottom of the annular shell 26 is connected with the annular cavity through a telescopic tube 28, a channel 29 connected with the annular cavity is provided inside the connecting rod 5, a heating cavity 30 is provided inside the arc plate 6, and the channel 29 is connected with the heating cavity 30. Start the second motor 21 to rotate its output shaft. The heat generated by the second motor 21 when it is working enters the annular shell 26 through the arc-shaped opening and the air inlet 27, then enters the annular cavity through the telescopic tube 28, and then enters the heating cavity 30 through the channel 29, so as to heat the arc plate 6. In winter, filamentous ice is formed in the soil body due to the freezing of water. When the arc plate 6 is separated, the filamentous ice will hinder the movement of the arc plate 6. By heating the arc plate 6, the filamentous ice in the soil body can be melted, so that the arc plate 6 will not be hindered by the filamentous ice when moving, thereby ensuring the smooth movement of the arc plate 6 and further ensuring the smooth avoidance. On hot days, the plunger 25 can be removed so that the heat of the second motor 21 can be dissipated through the pores.

[0037] like Fig. 9 As shown, one side of the arc plate 6 is provided with an arc section 31, and the other side of the arc plate 6 is provided with an arc receiving surface that matches the arc section 31. The arc section 31 allows the arc plate 6 to cut the soil when it rotates after being separated, so that the arc plate 6 is subjected to less resistance and can rotate better.

[0038] like Figure 1As shown, the cover 24, the annular shell 26, the moving block 4, and the connecting rod 5 are made of stainless steel. This makes the heat conduction effect of the cover 24, the annular shell 26, the moving block 4, and the connecting rod 5 poor, so that the heat generated by the second motor 21 can be lost less in the process of moving into the heating chamber 30, so that more heat can enter the heating chamber 30 to heat the soil and melt the filamentous ice.

[0039] The working principle of this embodiment is as follows:

[0040] Working principle: When in use, the bracket 1 is placed on the soil surface, the third motor 23 is started to make its output shaft rotate forward to drive the screw 22 to rotate, so that the ring frame 2 is driven to descend, thereby driving the ring plate 3, the mounting frame 32, the moving block 4, the connecting rod 5, and the arc plate 6 to descend, and the second motor 21 is started to make its output shaft rotate with the connecting shell 20 and the ring plate 3, so that the moving block 4, the connecting rod 5 and the arc plate 6 rotate, so that the pointed cone columnar component composed of the four arc plates 6 is drilled into the soil. After the drilling is completed, the third motor 23 and the second motor 21 are stopped. At this time, the top position of the arc plate 6 The first spring 9 is pressed against the surface of the soil, and the second spring 13 is pressed against the vertical plate 11 to generate a force, and then the second motor 21 is started to realize the rotation of the arc plate 6 and the driving sampling plate 7, so that the soil at different levels can be collected into the sampling cavity. The second motor 21 is then turned off, and the reverse knob 15 is turned on to make the push rod 14 rise, and the second spring 13 releases its force to bring the vertical plate 11 and the squeeze block 12 up, and the first spring 9 releases its force to bring the movable plate 8 and the sampling plate 7 back to their original positions, and the third motor 23 is started to reverse its output shaft, and the reverse is achieved, the annular frame 2 rises and resets, so that the arc plate 6 is taken away from the soil, and the sampling plate 7 can be pushed out again in the same way as above to remove the soil, so as to realize the drilling sampling of soil at different levels. When the arc plate 6 is drilling into the soil, a stone in the soil body blocks the movement of the arc plate 6. When the condition is reached, the third motor 23 and the second motor 21 are stopped, and the first motor 19 is started to rotate its output shaft forward to rotate the second bevel gear 18, thereby driving the first bevel gear 17 and the screw rod 16 to rotate, so that the moving block 4 moves, and the four moving blocks 4 move away from each other, so that the connecting rod 5 and the arc plate 6 move accordingly, so that the four arc plates 6 are separated, and then the third motor 23 and the second motor 21 are started again to realize the rotation and descent of the arc plate 6, so that it can avoid stones and continue to descend to the required depth, thereby avoiding stones and ensuring smooth sampling;Start the second motor 21 to rotate its output shaft. When the second motor 21 is working, the heat generated enters the annular shell 26 through the arc-shaped opening and the air inlet 27, then enters the annular cavity through the telescopic tube 28, and then enters the heating cavity 30 through the channel 29, so as to heat the arc plate 6. In winter, due to the freezing of water inside the soil, filamentous ice is formed inside the soil. When the arc plate 6 is separated, these filamentous ice will hinder the movement of the arc plate 6. By heating the arc plate 6, the filamentous ice in the soil can be melted, so that the arc plate 6 will not be hindered by the filamentous ice when moving, ensuring the smooth movement of the arc plate 6, and then ensuring the smooth avoidance. In hot weather, the plunger 25 can be removed so that the heat of the second motor 21 can be dissipated through the air holes. ;
