Technical Field

[0001] This utility model relates to the field of rotary drilling rig barrel technology, specifically a rotary drilling rig barrel. Background Technology

[0002] Rotary drilling is a construction technique used for hole drilling in building foundation engineering. It uses tools such as a drill bucket to rotate and cut soil and lift soil cuttings to complete the drilling. It is suitable for large-scale foundation construction such as high-rise buildings, bridges, and municipal facilities. It is mainly used for geological conditions such as sandy soil, cohesive soil, and silty soil, and is involved in various construction scenarios such as cast-in-place piles, continuous walls, and foundation reinforcement. Rotary drilling requires a drill barrel to operate.

[0003] Existing patent CN221032430U discloses a noise-reducing rotary drilling bit structure, including a rotary drilling barrel. The top of the rotary drilling barrel has a drill rod connection port. Hydraulic jacks are installed on both sides of the upper part of the rotary drilling barrel. Two hydraulic jacks are connected to a power source via hydraulic lines. Lifting rods are installed at the lower part of each hydraulic jack, and both lifting rods are located inside the rotary drilling barrel. A circular steel wing plate is connected to the lower part of the two lifting rods. A rotary drilling bit base is installed at the bottom opening of the rotary drilling barrel. Drill teeth are installed at the lower part of the rotary drilling bit base. An opening communicating with the interior of the rotary drilling barrel is provided on the rotary drilling bit base. One side of the rotary drilling bit base is hinged to the rotary drilling barrel, and the other side is detachably connected to the rotary drilling barrel. This invention avoids the method of shaking the barrel during soil discharge, effectively reducing noise and mitigating noise pollution to the surrounding environment and residents.

The drive shaft 28 and the rotating shaft 24 are rotatably connected to the pusher plate 23. The main gear 27 and the driven gear 26 mesh. The model of the motor 29 can be YCT225-4A. By adding the auxiliary drill barrel 21, the hole quality can be improved. It can also play a guiding role during drilling, ensuring the drilling inclination, shortening the drilling time, and improving drilling efficiency. The hydraulic cylinder 22 can push the pusher plate 23 to move vertically, which can remove the residual soil and debris from the inner wall of the auxiliary drill barrel 21 and the main drill barrel 1. At the same time, the motor 29... The main gear 27 can rotate, which in turn controls the rotation of the driven gear 26, thereby driving the rotating shaft 24 and the spiral blade 25 to rotate. This assists in the rapid discharge of excavated soil from the main drill barrel 1 and the auxiliary drill barrel 21, improving the efficiency of excavated soil discharge. A stabilizing disc 41 is fixedly connected to the outside of the rotating shaft 24. A support groove 42 is formed on the top of the pusher plate 23 along the axis of the rotating shaft 24. Support blocks 43 are slidably connected to both sides of the support groove 42. The top of the support blocks 43 is fixedly connected to the bottom of the stabilizing disc 41. Rotation of the rotating shaft 24 can drive the stabilizing disc 41 to rotate, which in turn drives the support blocks 43 to rotate. The support block 43 and the stabilizing plate 41 can improve the rotational stability of the rotating shaft 24 and reduce the probability of it swinging. The top of the pusher plate 23 is fixedly connected to the protective box 71, and the motor 29 is fixedly connected to the protective box 71. The protective box 71 is located outside the main gear 27 and the driven gear 26. The protective box 71 can protect the main gear 27 and the driven gear 26, prevent them from being contaminated by impurities, and ensure their stable operation. The bottom of the rotating shaft 24 is fixedly connected to the insertion rod 81.

A sealing ring 61 is provided on the inner wall of the sliding port 34. The sealing ring 61 adheres to the inner wall of the sliding port 34 and seals the gap between the sliding port 34 and the push rod 35, preventing slag from entering the cavity 33.

[0020] Working principle: During operation, when it is necessary to discharge excavated soil, the hydraulic cylinder 22 operates to push the pusher plate 23 downward. The downward movement of the pusher plate 23 drives the rotating shaft 24 to move, simultaneously discharging the excavated soil from the main drill barrel 1 and the auxiliary drill barrel 21, preventing residue from remaining on their inner walls. The motor 29 starts, driving the drive shaft 28 to rotate. The rotation of the drive shaft 28 drives the main gear 27 to rotate, which in turn drives the driven gear 26 to rotate. The rotation of the driven gear 26 drives the rotating shaft 24 to rotate, which in turn drives the spiral blades 25 to rotate. The rotation of the spiral blades 25 assists in pushing the excavated soil out quickly. As the pusher plate 23 moves downward... As the device continues to move downwards, all the slag in the auxiliary drill barrel 21 and the main drill barrel 1 can be discharged. While the rotating shaft 24 is rotating, it can also drive the fixed plate 31 to rotate. The rotation of the fixed plate 31 can drive the scraper 38 to rotate, which can clean the slag at the bottom of the discharge plate and prevent slag residue. At the same time, the spring 37 is initially in a compressed state, which can push the scraper 38 to make close contact with the pusher plate 23 when the scraper 38 is worn, which can ensure the cleaning effect and reduce the replacement frequency. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
