Rapid icebreaking drilling mechanism

Abstract

The invention relates to the field of electric drills, in particular to an ice-surface electric drill bit. A rapid icebreaking drilling mechanism comprises a middle rod, a spiral blade and a motor, wherein the spiral blade is spirally and fixedly wound around the middle rod, an output shaft of the motor is connected to the top of the middle rod through a transmission mechanism and drives the middle rod to rotate, an icebreaking piton is arranged at the bottom of the middle rod, the center of the outer side of the bottom of the middle rod is symmetrically provided with a pair of icebreaking blades which are arranged in an inclined mode, the bottom edge of each icebreaking blade is provided with sawteeth, the top edge of one icebreaking blade is connected with the spiral blade, and the end face of each icebreaking blade is provided with an electric heating piece in an adhering mode. According to the rapid icebreaking drilling mechanism, the bottom of the electric drill bit is provided with the pair of icebreaking blades with the sawteeth, the ability to smash an ice surface of the drill bit is enhanced by means of the sharp corners of the sawteeth, holes can be smoothly drilled in the surface by means of pressure and rotating torque provided by a small motor of agricultural machinery, and convenience is brought to fishing carried out by fishmen in the northern area.

Description

technical field [0001] The invention relates to the field of electric drills, in particular to an ice surface electric drill bit. Background technique [0002] In the northern region, because the temperature is very low, the river water will freeze very thickly in winter. When fishermen want to catch fish, they need to cut through the thick ice. Now most of the fishermen dig holes for fishing on the ice by hand. The diameter of the holes is about 20-50cm. figure 1 The tools shown are manually excavated, grasping the poles on both sides with both hands, breaking the ice with the sharp cone at the bottom, and then shoveling off the ice chips with a shovel. It takes at least 10 minutes to dig a hole, which is very inefficient and labor-intensive. . Some people have also thought about using electric drills to drill holes in the ice, but the existing electric drills that can be placed on small agricultural machinery can provide little drilling pressure, and the ice itself is r...

Now most of the fishermen dig holes for fishing on the ice by hand. The diameter of the holes is about 20-50cm. figure 1 The tools shown are manually excavated, grasping the poles on both sides with both hands, breaking the ice with the sharp cone at the bottom, and then shoveling off the ice chips with a shovel. It takes at least 10 minutes to dig a hole, which is very inefficient and labor-intensive.

Some people have also thought about using electric drills to drill holes in the ice, but the existing electric drills that can be placed on small agricultural machinery can provide little drilling pressure, and the ice itself is relatively hard and very dense and smooth. , when the drill bit rotates at high speed, it will evaporate ice debris to generate water vapor, and the water vapor covering the drill bit will also play a lubricating role, so the general drill bit cannot drill holes on the ice layer at all, and there is a lack of a simple one that can drill on the ice layer. hole tool
