Description

A dust-free and environment-friendly electric hammer

technical field

The invention relates to the technical field of dust-free and environment-friendly electric hammers, in particular to a dust-free and environment-friendly electric hammer.

Background technique

Electric hammer is a kind of electric tool. Electric hammer is a kind of electric drill. It is mainly used to drill holes in concrete, floors, brick walls and stone materials. It is specially used for drilling holes on walls, concrete and stone materials. In response to the development and production needs of modern society, many types of electric hammers have appeared on the market. There are electric hammers that can be adjusted to the appropriate position and can be equipped with appropriate drill bits to replace ordinary electric drills and electric hammers used in electric picks. On the basis, a piston with a crankshaft and connecting rod driven by an electric motor is added to reciprocate and compress air in a cylinder, so that the air pressure in the cylinder changes periodically, and the changed air pressure drives the hammer in the cylinder to reciprocate and hit the top of the drill bit. Like we use a hammer to hit the drill bit. So it is called an electric hammer. Because the drill bit of the electric hammer rotates and produces frequent impacts along the direction of the electric drill rod, it can be used in brittle cement concrete and Quickly punch holes in stone and other materials, the high-grade electric hammer can use the switch to make the drill bit of the electric hammer in different working states, that is, only rotate without impact, only impact without rotation, both impact and rotation, in the traditional hammer and iron hammer Drilling with one hammer and one hammer, until the motor drives the drill bit to helically drill, and develops into the current electric hammer cylinder drilling. Step by step, the drilling work is easier, more efficient and labor-saving, and the diameter of the hole, the shape of the hole , the depth of the hole has become controllable, the human operation has been liberated, and the safety and efficiency of the work have also been greatly improved. However, during the development of the point hammer development process, the electric hammer is easy to cause a lot of dust and debris. Flying makes the working environment worse, and the problem of harm to human health has not been effectively solved. The following problems exist in the implementation of the traditional dust-free and environmentally friendly electric hammer;

1. The collection of dust is not perfect enough. Although it can have a concentrated treatment effect on the splashed dust and debris, it cannot guarantee complete removal. For the splashed dust and debris floating in the working environment, it increases the follow-up The cleaning of the environment increases the workload;

2. It is more troublesome to replace the collected debris storage bag, the operation is not convenient enough, and the time-saving and labor-saving effect of the original electric hammer cannot be achieved. It takes a lot of steps for the operator to replace the storage bag, and due to the relationship between the suction of the fan , will make part of the dust move to the direction of the fan, causing pollution to the pipe wall and fan, which is not conducive to subsequent use, and at the same time increases the difficulty of the maintenance and cleaning of the electric hammer as a whole.
