Description

A dust-free and environment-friendly electric hammer

technical field

The invention relates to an electric hammer, in particular to a dust-free and environment-friendly electric hammer.

Background technique

The electric hammer is an electric rotary hammer drill with a safety clutch attached to a pneumatic hammering mechanism. It is a type of electric drill. Compress air back and forth in a cylinder, so that the air pressure in the cylinder changes periodically, and the changing air pressure drives the hammer in the cylinder to strike the top of the electric hammer drill back and forth, just like we hit the electric hammer drill with a hammer. Hence the name electric hammer;

During the working process of the electric hammer, a lot of dust is usually generated due to vibration. These dusts permeate the working environment. After the operator inhales the lungs, it will cause lung discomfort, ranging from coughing and throat discomfort to severe silicosis. , will cause great harm to the operator's body, seriously affect the health and work efficiency of workers, and will also cause certain pollution to the surrounding environment. According to investigations, construction dust is the cause of smog in today's society one;

The dust removal device of the electric hammer has been studied at home and abroad, but the dust removal device of the electric hammer that can be used in production is very rare. Even the existing dust removal device of the electric hammer that can be produced and put into use has a very low dust removal efficiency, and The price is particularly expensive, and it is difficult to achieve real popularization in applications.

detailed description

The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is based on the technical solution of the present invention, and provides detailed implementation methods and specific operating procedures, but the scope of protection of the present invention is not limited to the following embodiments. .

As shown in the figure, a dust-free and environmentally friendly electric hammer includes an electric hammer body 1, an electric hammer drill bit 2 is installed on the electric hammer body, an electric hammer drill bit 2 is installed on the electric hammer body 1, and three sets of drainage tubes pass through the electric hammer The drill bit 2 is also fixed on the electric hammer body, and as an air flow channel, the drainage tube 3 sucks the dust around the electric hammer drill bit 2 of the electric hammer body into its interior, and filters it, and finally the dust falls into the collector fixed on the drainage tube 3 In the dust tank 5, in order to clean up the dust collected in the dust tank 5 in time, the dust tank 5 is detachably fixed on the drainage pipe. And set the corresponding screw thread at the interface of the drainage pipe 3, so that the dust collection tank 5 can be screwed on the drainage tube, and when there is too much dust in the dust collection tank, it can be easily completed by screwing it down and pouring out the dust Cleaning work; in order to make the airflow in the draft tube 3 move directionally, the exhaust wheel 6 is housed on the draft tube, as shown in Figure 2 and Figure 3, the described exhaust wheel 6 includes blades 602, blade main shaft 603 and peripheral Housing 601, the housing 601 is a cylindrical shape with one end open, and its bottom is provided with a plurality of exhaust holes 7, the blade main shaft 603 passes through the bottom of the housing 601, and the part equipped with the blades 602 is located inside the housing 601, and the blades The main shaft 603 is driven by the motor 8. When the blade main shaft 603 rotates, the rotation of the blade 602 can make the gas in the housing 6 flow from its open end to the bottom and be discharged from the exhaust hole 7 (the principle of the exhaust wheel 6 is similar to The existing centrifugal fan on the market can be replaced by it), when installing the exhaust wheel 6, the air inlet should be used as the butt joint end, so that the exhaust wheel 6 is connected with the drainage pipe 3, so that the exhaust wheel 6 can make the The gas in the drainage pipe 3 flows to the exhaust wheel 6 and flows out from the exhaust hole 7 at the bottom of the exhaust wheel. In order to achieve the dust collection effect, a dust removal net 9 needs to be set at the connection between the exhaust wheel 6 and the drainage tube 3, as As shown in Fig. 4, one is used to collect dust and make it gather on the dust removal net 9, when the dust on the dust removal net reaches a certain amount, it will fall off due to the vibration generated when the electric hammer drill bit 2 is working normally, and finally fall into the dust collector In the dust tank 5, if the dust removal net 9 is clogged, it can be handled by slightly knocking, or the exhaust wheel 6 is removed, and the dust removal net 9 is cleaned or replaced.

In order to rationally configure the space occupied by the drainage tube 3, the dust collection tank 5, the exhaust wheel 6 and the motor 8, there are two embodiments here, one, the cylindrical drainage tube 3 can be selected, and it is arranged above the drainage tube 3 The wind exhaust wheel 6 is provided with the dust collection tank 5 below it, and the exhaust wind wheel 6 is relatively up and down with the dust collection tank 5, as shown in Figure 6, the motor 8 is arranged on the end of the exhaust wind wheel 6 with the air discharge hole 7 In this way, the motor 8 drives the exhaust wheel 6 to operate, and the airflow in the drainage pipe 3 is sucked to the exhaust wheel 6, and the dust is filtered through the dust removal net 9 and collected in the dust collection tank 5; The shape of the pipe 3 is reasonably changed. For example, the drainage pipe 3 is made into two sections, which are respectively a horizontal section 301 and a vertical section 302. On the body, the vertical section 302 is vertically connected with the horizontal section to form a T shape, the exhaust wheel 6 is fixed on the vertical section 302 of the drainage pipe 3 , and the dust collection tank 5 is arranged at the bottom of the vertical section 302 .

The arrangement of the drainage pipe 3 , the dust collecting tank 5 and the exhaust wheel 6 is not limited to the above-mentioned ones, and those skilled in the art can make reasonable changes according to the scheme disclosed in the present invention, which will not be listed here.

Since the drainage tube 3 is set through the electric hammer drill bit 2 and fixed on the hammer body, the drainage tube 3 may hinder the normal operation of the electric hammer drill bit 2. For this, the length of the drainage tube 3 can be properly controlled, and the Its front end is provided with a trumpet-shaped dust collection cover 4, and the dust collection cover 4 is composed of a plurality of strips radially fixed on the front end of the drainage tube 3. It can be squeezed backwards and spread out under the blocking effect of the wall, not only will not affect the normal operation of the electric hammer drill 2, but also form a barrier ring to prevent the dust from diffusing to the outside, which is more conducive to the drainage tube to guide and collect the dust .

The parts not described in the present invention are prior art.
