Technical Field

[0001] This utility model relates to the field of backhoe hydraulic drilling rig technology, and in particular to a rapid drilling device suitable for backhoe hydraulic systems. Background Technology

[0002] The backhoe hydraulic drilling rig is an important piece of engineering machinery used for drilling. It is commonly used in mining, foundation construction, geological exploration, and other fields.

[0003] Existing hydraulic drilling rigs for backhoes often only allow drilling in a straight up-and-down motion. When encountering special terrain, it may be necessary to drill at an angle, making it difficult for existing drilling devices to meet the usage requirements. Therefore, in view of the above situation, there is an urgent need to develop a fast drilling device suitable for backhoe hydraulic systems that is convenient for drilling and allows for adjustment of the drilling angle to meet different drilling needs, in order to overcome the shortcomings in current practical applications and meet current requirements.

[0008] Furthermore, the angle adjustment mechanism includes a third gear and a driving component; the third gear is mounted and fixed on the support shaft; the driving component drives the third gear to rotate.

[0009] Furthermore, the driving component includes a first electric telescopic rod and a rack connected to the telescopic end of the first electric telescopic rod; the rack meshes with the third gear; and the first electric telescopic rod is fixed on the adapter frame.

[0010] Furthermore, the driving component also includes a slider and a slide rail that slide in a sliding fit; the slider is mounted on the rack, the slide rail is fixed on the adapter frame, and the slide rail is parallel to the rack.

[0011] Furthermore, the drilling mechanism includes a hydraulic cylinder, a lifting plate, a drill bit, and a drill bit rotation assembly; the hydraulic cylinder is fixed to the frame, and the telescopic end of the hydraulic cylinder is fixed to the lifting plate, driving the lifting plate to rise and fall; the drill bit is rotatably connected below the lifting plate; the drill bit rotation assembly is mounted on the lifting plate and connected to the drill bit, driving the drill bit to rotate.

Furthermore, the angle of the drilling mechanism is fixed by the locking mechanism, thus meeting the needs of different drilling angles. This rapid drilling device, applicable to backhoe hydraulic systems, operates by using a hydraulic motor to drive the first gear, second gear, and drill bit to rotate. A hydraulic cylinder drives the lifting plate and drill bit to move downwards, allowing the drill bit to drill a hole in the ground. Additionally, a first electric telescopic rod drives the rack to move up and down, which in turn drives the third gear to rotate. The rotation of the third gear drives the support shaft and frame to rotate, which in turn drives the drilling mechanism to rotate, thereby adjusting the drilling angle. After adjustment, a second electric telescopic rod drives the locking plate to firmly press against the adapter frame, making the connection between the frame and the adapter frame more stable. In summary, this utility model facilitates drilling and allows for adjustment of the drilling angle to meet different drilling needs. Attached Figure Description

Two locking mechanisms 6 that pass through the adapter frame 1 are fixedly installed on the rear side of the frame 2. A drilling mechanism 3 is installed on the front side of the frame 2. In use, drilling is performed through the drilling mechanism 3. In addition, the angle adjustment mechanism 5 drives the support shaft 201 and the frame 2 to rotate. The rotation of the frame 2 drives the drilling mechanism 3 to rotate, thereby adjusting the drilling angle of the drilling mechanism 3. After adjustment, the locking mechanism 6 is locked onto the adapter frame 1 to improve the stability of the frame 2.

[0027] The drilling mechanism 3 includes: a hydraulic cylinder 301, a lifting plate 302, a hydraulic motor 303, a first gear 304, a second gear 305, and a drill bit 306.

The lifting plate 302 is slidably connected to the limiting rods 4. In use, the first gear 304, the second gear 305 and the drill bit 306 are driven to rotate by the hydraulic motor 303. The lifting plate 302 and the drill bit 306 are driven to move down by the hydraulic cylinder 301, so that the drill bit 306 drills a hole in the ground.

[0028] The angle adjustment mechanism 5 includes: a first electric telescopic rod 501, a rack 502, a third gear 503, a slider 504, and a slide rail 505.

When the second electric telescopic rod 601 drives the locking plate 602 to separate from the adapter frame 1, the frame 2 can be rotated by the angle adjustment mechanism 5.

[0030] The hydraulic cylinder 301 and hydraulic motor 303 mentioned above are both controlled by a hydraulic system. The hydraulic system is installed on the backhoe hydraulic drilling rig (not shown in the figure).

In addition, the first electric telescopic rod 501 drives the rack 502 to move up and down. The movement of the rack 502 drives the third gear 503 to rotate. The rotation of the third gear 503 drives the support shaft 201 and the frame 2 to rotate. The rotation of the frame 2 drives the drilling mechanism 3 to rotate, thereby adjusting the drilling angle of the drilling mechanism 3. After adjustment, the second electric telescopic rod 601 drives the locking plate 602 to press tightly against the adapter frame 1, making the connection between the frame 2 and the adapter frame 1 more stable.
