Problems solved by technology
[0002] At present, when the soil drilling machine is changing the drill pipe, the connection between the switching device and the drill pipe is usually connected by a threaded connection, which often causes the wires at both ends of the drill pipe to loosen at the same time, which is time-consuming, laborious, and poor in safety, which seriously affects the operating efficiency of the machine mouth. , and even sometimes plugging will occur when the drilling hole encounters a sand layer

The invention relates to a drilling machine rod change device which solves the problems that a traditional screw thread is not firm in connection, time and labor are wasted, safety is poor, operation efficiency is low, a rod is easily plugged and the like. The drilling machine rod change device comprises a conduction device and a drilling rod, the conduction device comprises a conduction column and a sleeve, a cavity is formed in the conduction column, the sleeve is sleeved outside the conduction column and provided with a water filling nozzle, a flange plate is arranged at the top of the conduction column, a switchover cover is arranged at the bottom of the conduction column, a T-shaped connector is formed in the switchover cover, and a flange is arranged on the drilling rod and connected with the T-shaped connector in the switchover cover in a matched and clamped manner. The drilling machine rod change device is ingenious in design, simple in structure, convenient and rapid to use, easy to manufacture, low in cost, convenient to maintain, high in safety and convenient, rapid, firm and reliable in connection, the operation efficiency of a machine opening is greatly improved, the labor intensity of staff is reduced, rod change time is largely shortened, and the rod is not easily plugged when a hole is drilled in a sand bed. The drilling machine rod change device is applied to production practice and fine in effect, and meets design requirements.
Description
technical field [0001] The invention relates to the technical field of soil drilling construction, in particular to a rod changing device for a drilling machine. Background technique [0002] At present, when the soil drilling machine is changing the drill pipe, the connection between the switching device and the drill pipe is usually connected by a threaded connection, which often causes the wires at both ends of the drill pipe to loosen at the same time, which is time-consuming, laborious, and poor in safety, which seriously affects the operating efficiency of the machine mouth. , Even sometimes when the borehole encounters a sand layer, the plugging phenomenon will also occur. Contents of the invention [0003] The object of the present invention is to provide a brand-new rod changing device for a drilling machine in order to solve the above-mentioned problems in the prior art. [0004] The present invention is achieved through the following technical solutions: [00...
