Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, in particular to a reinforced drill bit. Background Art

[0002] A drill bit is a cutting tool used by a general drill or drilling machine to cut a circular hole. The basic principle of a drill bit is to rotate the drill bit cutting edge, cut the workpiece, and then remove the drill cuttings through the drill groove. Commonly used drill bits include twist drills, flat drills, center drills, deep hole drills and casing drills. Existing drill bits have a cutting face configured to drill into a formation (e.g., a rock formation). In some cases, the base face of the drill bit may be spaced apart from the proximal end of the cutting face, and an axially extending wall extends between the base face and the cutting face.

[0003] After searching, a Chinese patent discloses a long spiral reinforced drill bit (authorization announcement number CN202325248U), including a drill core and spiral blades. The upper end of the drill core is provided with a connection portion connected to the drill rod, and the lower end of the drill core is provided with a drill tip. The drill core includes an upper center tube, and the spiral blades are arranged on the outer periphery of the upper center tube. The lower end of the upper center tube is fixed with an integral casting portion, and the integral casting portion includes a lower center tube coaxially connected to the upper center tube and a lower spiral blade integrally formed on the lower center tube. Although this patented technology can make the double spiral blades more firmly connected, it is not easy to be damaged during the drilling process.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the current drill bit will generate a lot of dust when in use, which can be easily inhaled by the staff, thereby causing harm to the health of the staff and greatly reducing the practicality of the equipment. Utility Model Content

[0006] The technical solution of the utility model is as follows: a reinforced drill bit comprises a drill rod, one end of the drill rod is fixedly installed with a drill bit body, the outer side of the drill rod is fixedly connected with an annular water tank, one side of the annular water tank is fixedly connected with a bellows, the side of the bellows away from the annular water tank is fixedly connected with a dust cover, both ends of the inside of the drill rod are provided with sliding grooves, the inside of the sliding grooves are rotatably connected with threaded rods, the outer sides of the threaded rods are threadedly connected with threaded plates, the threaded plates are fixedly connected to the inner wall of the dust cover, two motors are fixedly installed on the top of the drill rod, the output shafts of the motors extend to the inside of the sliding grooves and are fixedly connected to the corresponding threaded rods, the motors are equipped with batteries inside, a controller is fixedly installed on the top of the drill rod, and a wireless signal transceiver is fixedly installed on the top of the drill rod.

[0007] By adopting the above technical solution, the dust cover is driven to move downward or upward by the rotation of the threaded rod, and the dust cover can have a certain ductility through the action of the bellows, so that it can contact the drilled ground, reduce the dust floating on the drill body during use, and thus reduce the inhalation of dust by the staff.

[0008] As a preferred embodiment, a plurality of liquid inlet holes are opened inside the drill bit body, a plurality of delivery pipes are arranged inside the drill rod, one end of the delivery pipes extends to the inside of the annular water tank, and the end of the delivery pipes away from the annular water tank extends to the inside of the corresponding liquid inlet holes, and the inside of the annular water tank is filled with cutting fluid.

[0009] By adopting the above technical solution, the cutting fluid in the annular water tank will be transported to the corresponding liquid inlet hole through the delivery pipe. The cutting fluid is an emulsion with good cooling performance, lubrication performance, rust prevention performance and pollution-free characteristics.

[0010] As a preferred embodiment, a transmission end is fixedly mounted on one end of the drill rod away from the drill bit body.

[0011] By adopting the above technical solution, the rotation of the transmission end can drive the rotation of the drill rod, and then drive the rotation of the drill bit body.

[0012] As a preferred implementation, one end of the dust cover away from the bellows is fixedly connected to a resistance cover.

[0013] By adopting the above technical solution and using the resistance cover, the leakage of dust can be reduced.

[0014] As a preferred implementation, a liquid inlet pipe is fixedly connected to the top of the annular water tank, and a threaded cover is provided at the top of the liquid inlet pipe.

[0015] By adopting the above technical solution and using the liquid inlet pipe, the cutting fluid can be introduced into the annular water tank.

[0016] The bottom ends of the drill body and the abutment cover are both coated with a zinc coating.

[0017] The provision of the galvanized coating can increase the wear resistance of the drill body and the bottom of the abutment cover.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, before the drill body is used, an instruction is sent to the wireless signal transceiver through the wireless terminal, and then the wireless signal transceiver transmits the information to the controller, and the controller controls the start of the motor to drive the threaded rod to rotate, which can drive the threaded plate to slide in the corresponding slide groove, and then drive the dust cover to move up or down, and through the action of the bellows, the dust cover can have a certain ductility and can contact the perforated ground, thereby reducing the phenomenon of dust floating during the use of the drill body, and then can reduce the inhalation of dust by the staff, thereby improving the practicality of the equipment.

In the utility model, when the drill body is in use, the cutting fluid in the annular water tank will be transported to the corresponding liquid inlet hole through the delivery pipe, and the cutting fluid is an emulsion, which has good cooling performance, lubrication performance, rust prevention performance and pollution-free characteristics.
