A slide bar 13 is fixedly connected to the top of the base 1, and the other end of the connecting rod 14 is slidably connected to the outside of the slide bar 13. The outer portion of the gear 17 is meshedly connected to the outer portion of the rack 16 .

[0032] Specifically, the output end of the second motor 18 plays a fixing role on the gear 17. By starting the second motor 18, the gear 17 meshes with the rack 16, so that the gear 17 moves along the outside of the rack 16, and the connecting slider 19 plays a fixing role on the second motor 18, and the connecting slider 19 plays a limiting role in the limiting groove 20, so that the connecting slider 19 is synchronously driven to move along the inner wall of the limiting groove 20, thereby guiding the gear 17 to move in a directional manner, thereby driving the connecting rod 14 to move along the outside of the slide rod 13, and the T-shaped slider 22 is limited in the T-shaped groove 21, thereby driving the T-shaped slider 22 to move along the inner wall of the T-shaped groove 21, so that one end of the conveying pipeline 3 can be raised and lowered, so that the conveying pipeline 3 can be adjusted more smoothly, and then under the action of the support block 2, the other end of the conveying pipeline 3 is fixed and rotated, which can improve the construction efficiency and adapt to different geological conditions.

[0033] Reference Figure 1 and Figure 2 The dust collection assembly includes a fan 9, which is fixedly connected to the top of the base 1. The other end of the fan 9 is fixedly connected to a collection box 10, and the other end of the collection box 10 is fixedly connected to a dust suction port 11. The top of the base 1 is fixedly connected to a support plate 12, and the bottom of the collection box 10 is fixedly connected to the top of the support plate 12.

[0034] Specifically, the base 1 fixes the fan 9. By starting the fan 9, the collecting box 10 is fixed at one end of the fan 9, so that the dust suction port 11 can collect the scattered dust when discharging the discharge pipe 5. The collecting box 10 fixes the dust suction port 11, so that the dust enters the collecting box 10 through the dust suction port 11 for better processing, thereby increasing the service life of the internal parts. The collecting box 10 is fixed at the top of the support plate 12, so that the collecting box 10 can be fixed.

[0036] Specifically, the outside of the conveying pipe 3 plays a fixing role on the feed pipe 4, so that when mud and stone enter the conveying pipe 3 through the feed pipe 4, the outside of the conveying pipe 3 plays a fixing role on the first motor 6, so that the first motor 6 is used to fix the spiral blade 7 at the output end of the first motor 6, and the spiral blade 7 is limited in the conveying pipe 3, thereby driving the spiral blade 7 to rotate on the inner wall of the conveying pipe 3, and the outside of the conveying pipe 3 plays a fixing role on the discharge pipe 5, so that the mud and stone are discharged through the discharge pipe 5.

[0037] Working principle: When using this device, by starting the second motor 18, the gear 17 moves along the outside of the rack 16, and the connecting slider 19 is synchronously driven to move along the inner wall of the limit groove 20, thereby guiding the gear 17 to move in a directional manner, thereby driving the connecting rod 14 to move along the outside of the slide rod 13, and then driving the T-shaped slider 22 to move, so that one end of the conveying pipe 3 can be lifted and adjusted, so that when one end of the conveying pipe 3 is lifted and moved, the T-shaped slider 22 is moved along the inner wall of the T-shaped groove 21 through the action of the T-shaped groove 21, so that the conveying pipe 3 is more stable when adjusted, and then under the action of the support block 2, the other end of the conveying pipe 3 is fixed and rotated, which can not only improve the construction efficiency and adapt to different geological conditions, but also meet diversified production needs. When mud and stone enter the conveying pipe 3 through the feed pipe 4, the first motor 6 is activated, thereby driving the spiral blade 7 to rotate on the inner wall of the conveying pipe 3, so that the mud and stone are discharged through the discharge pipe 5;

[0038] When the mud and rocks are discharged, the fan 9 is started so that the dust suction port 11 collects the scattered dust when the discharge pipe 5 is discharged. In this way, the dust enters the collection box 10 through the dust suction port 11 for better processing, thereby increasing the service life of the internal parts.
