Impacting type ice driller

Abstract

The invention provides an impacting type ice driller. The impacting type ice driller comprises a rack, a motor mounted on the rack and a drilling rod capable of being driven by the motor to rotate, and is characterized by further comprising a fixed part and a rotary part, which are oppositely arranged in the axial direction, wherein the rotary part is connected with the drilling rod, and can keep synchronous motion with the drill rod under the driving of the motor; irregular surfaces, which are matched with each other, are arranged on relative end faces of the fixed part and the rotary part; and the rotary part can do axial reciprocating motion relative to the fixed part through mutual contact and separation action of the irregular surfaces when the rotary part rotates. The impacting type ice driller has the advantages that the irregular surfaces, which are matched with each other, are arranged on the relative end faces of the fixed part and the rotary part, and the rotary part can do the axial reciprocating motion relative to the fixed part through the mutual contact and the separation action of the irregular surfaces when the rotary part rotates, so that an impacting effect is generated on an ice layer in an ice drilling process of the drilling rod, and the drilling effect is relatively good.

Description

technical field [0001] The invention relates to a mechanical device for drilling ice, in particular to an impact ice drilling machine. Background technique [0002] In the past, people usually used chisels to drill holes in the ice layer. Manual ice drilling was not only time-consuming and laborious, but also the ice drilling effect was poor, and it was difficult to drill ideal ice holes. In order to overcome the above-mentioned defects of manual ice drilling, various automatic ice drilling machines have been invented. The existing automatic ice drilling machines generally include a frame, a motor and a drill. The motor is installed on the frame, and the drill is installed on the output of the motor on axis. When the ice drilling machine is working, the ice drilling machine is erected on the ice surface. After the motor is started, the drill bit is driven to rotate, and the drill bit rotates inside the ice layer to complete the entire ice drilling process. Although the exi...

AI Technical Summary

Problems solved by technology

Although the existing automatic ice drilling machine has realized automatic operation and greatly improved work efficiency, because the drill bit is fixedly connected with the output shaft of the motor, the drill bit cannot move axially reciprocating relative to the output shaft of the motor, so the drill bit When drilling ice, the ice can only be shaved by rotating, that is, the drill bit cannot produce up and down impact on the ice layer while rotating. In addition, because the ice layer is slippery and brittle, it is very difficult for the drill bit to rotate in the ice layer. Easy to slip, which leads to poor ice drilling effect
