Figure 1 and Figure 2 As shown, a sliding block 14 is welded on one side of the first motor 6 facing the base 1, and the outside of the sliding block 14 is connected to the internal sliding slot of the base 1. The first motor 6 can be restricted by the sliding block 14 to adjust its horizontal position longitudinally after transmission. An auger 5 is welded on the output shaft of the first motor 6. The auger 5 in contact with the soil can be rotated by the output of the first motor 6, and the spiral part around the auger 5 can make the soil discharged from the outside of the hole as it rotates.

Figure 3 , Figure 4 and Figure 5As shown, tooth grooves 15 for transmission are provided on both sides between the second transmission plate 8 and the first transmission plate 7, and a gear 16 for transmission is provided between the two tooth grooves 15, and the outer portion of the gear 16 is meshed and connected with the outer portion of the tooth groove 15. When the first transmission plate 7 moves longitudinally with the first motor 6, the horizontal position of the second transmission plate 8 is driven by the transmission of the gear 16 and the tooth groove 15;

[0025] In this embodiment, a second threaded rod 17 is disposed on one side of the outer portion of the second transmission plate 8, and the upper and lower ends of the second threaded rod 17 are rotatably connected to the inner portion of the second transmission plate 8, such as Figure 4 and Figure 5 As shown, a transmission frame 10 is disposed at the upper end of one side of the outer portion of the second threaded rod 17, and a third motor 18 is disposed at the upper end of the second threaded rod 17. The output shaft of the third motor 18 can drive the second threaded rod 17 to rotate, and the outer portion of the second threaded rod 17 and the inner portion of the transmission frame 10 generate relative motion. The transmission frame 10 is restricted by the second transmission plate 8 and is converted from a rotational motion to a longitudinal linear motion. The longitudinal linear motion can adjust the structure of the position connection of the transmission frame 10.

[0026] In this embodiment, the second shifting bars 20 are disposed on both sides of the transmission frame 10, and the first shifting bar 19 is disposed at the front end between the two second shifting bars 20. Figure 5 As shown, the two second toggle bars 20 and the first toggle bar 19 are located around the upper end of the first motor 6, and the rotation of the second threaded rod 17 can make the first toggle bar 19 and the second toggle bar 20 move longitudinally downward and contact the soil pile produced by excavation, contacting the upper end position of the soil pile;

The sliding rail 21 restricts the connecting bar 22 and thus fixes the stability of the horizontal position adjustment of the second transmission plate 8.

[0029] Working principle: when using the device and excavating for the set pre-take, after pushing the base 1 and the auger 5 to the desired position by the handle 3, the limiting bar 4 contacts the ground and makes the auger 5 in a horizontal state, the first motor 6 is started, and the output shaft of the first motor 6 can drive the auger 5 to rotate, and the second motor 13 is started, and the output shaft of the second motor 13 can drive the first threaded rod 9 to rotate, and the rotation of the first threaded rod 9 can produce relative movement with the outer wall of the first motor 6. After the first motor 6 is restricted by the sliding block 14, the auger 5 is converted from rotational motion to longitudinal linear motion. During the longitudinal movement of the first motor 6, the first motor 6 will drive the first transmission plate 7 to adjust the horizontal position, and the tooth groove 15 on the surface of the first transmission plate 7 will drive the second transmission plate 8 with the tooth groove 15 to adjust the position through the gear 16. The adjustment of the position of the second transmission plate 8 can directly adjust the position of the first toggle bar 19 and the second toggle bar 20. As the auger 5 moves downward longitudinally, the position of the first toggle bar 19 and the second toggle bar 20 is adjusted. After excavation, the auger 5 needs to be recovered. When the auger 5 is recovered, The third motor 18 is started, and the output shaft of the third motor 18 can drive the second threaded rod 17 to rotate. The second threaded rod 17 can generate relative motion with the transmission frame 10. The transmission frame 10 is restricted by the second transmission plate 8 to convert the rotational motion into longitudinal linear motion, so that the first toggle bar 19 and the second toggle bar 20 move toward the periphery of the excavation position. After the first toggle bar 19 and the second toggle bar 20 move to the lowest end, the first toggle bar 19 and the second toggle bar 20 will contact the uppermost part of the excavated soil pile, and the first telescopic rod 11 is started. The contraction of the first telescopic rod 11 and the second telescopic rod 12 can realize the outward pushing of the contact position of the soil pile. During the pushing of the soil, the rotation of the second motor 13 is stopped. As the first telescopic rod 11 and the second telescopic rod 12 are contracted and reset, the second motor 13 is restarted, and the positions of the first toggle bar 19 and the second toggle bar 20 are further adjusted. After the positions of the first toggle bar 19 and the second toggle bar 20 are adjusted, the soil pushing and the stopping of the second motor 13 are repeated, thereby realizing the pushing of the soil from top to bottom layer by layer.
