Description

Cross alloy drill

Technical Field

The utility model belongs to the technical field of soil drilling tool, a cross alloy bores is related to.

Background

The drill is a tool for drilling through holes or blind holes in solid materials and reaming existing holes. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills. During digging, the drill bit rotates around the vertical shaft and moves axially. The soil is cut under the action of torque and axial force of the drill bit, is broken and loosened under the action of extrusion and centrifugal force of the working blades, forms soil flow and presses the pit wall, and meanwhile, the soil flow is lifted along the page and conveyed to the ground surface. When the soil flow moves to the position without pit wall blocking, the broken soil is thrown to the periphery of the pit due to the action of centrifugal force, and the whole pit digging process is completed; although the drill bit can realize the drilling function, the drill bit needs to be replaced to ream the drilled hole after drilling a hole, so that the operation of people is inconvenient, and meanwhile, the working efficiency is also reduced.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-3, the cross alloy drill of the present invention includes a drilling assembly 100, a drill bushing 200, a reaming assembly 300, and a reinforcement assembly 400.

The drill bushing 200 is fixedly sleeved on the drilling assembly 100, the pair of reaming assemblies 300 is arranged on the side surface of the drill bushing 200, when the drilling assembly 100 is in work, a cross-shaped alloy drill needs to be installed on the drilling machine, the drilling machine is started to drive the cross-shaped alloy drill to rotate, when the drilling assembly 100 is in contact with the ground, the drilling assembly 100 can drill the ground, and after the drilling assembly 100 is lowered to a certain depth, the reaming assemblies 300 can perform reaming work on holes drilled by the drilling assemblies 100, soil scraps are generated when the reaming assemblies 300 perform reaming on the holes or the drilling assembly 100 performs drilling on the ground, a plane where each reaming assembly 300 is located intersects with a central axis where the drill bushing is located, the intersection angle is a, and the intersection angle is an acute angle, so that the reaming assemblies 300 can lead the soil scraps out of the holes and discharge the soil scraps to the outside of the holes, and the drilling efficiency and the reaming efficiency of the cross-shaped alloy drill are improved, meanwhile, the soil scraps are prevented from blocking the holes.

The reinforcing component 400 is arranged between the drill bushing 200 and the reaming component 300, and through the arrangement of the reinforcing component 400, the connection strength between the reaming component 300 and the drill bushing 200 is effectively increased, and meanwhile, the rigidity of the reaming component 300 is also enhanced, so that the reaming component 300 is not easy to damage in the reaming process.

Each group of reaming assemblies 300 comprises a guide plate 310 fixedly connected with the drill bushing 200, an upper cutter slot 311 is formed in the bottom of each guide plate 310, an upper cutter blade 312 is installed on the upper cutter slot 311, when the reaming assemblies 300 are in a reaming process, the drilling assembly 100 continues to move downwards relative to the ground, the two upper cutter blades 312 rotate with the central axis of a drilled hole, and when the upper cutter blades 312 contact the soil on the ground, the upper cutter blades 312 cut soil, and the guide plate 310 at the moment is in the rotating process, so that the soil cut off can move along the inclined surface of the guide plate 310, and the soil is discharged to the outside from the hole.
