Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

In the first embodiment, as shown in fig. 1 to 3, the dust collection device according to the embodiment of the invention includes an angle grinder 1, a housing 2 is covered on a grinding wheel of the angle grinder 1, an opening is formed at the bottom of the housing 2, dust discharge holes 21 are formed at both front and rear ends of the housing 2, and the dust discharge holes 21 are connected with a dust collection pipeline. Angle grinder 1 is because the emery wheel is rotatory at the during operation, and the dust particulate matter that splashes is got rid of to front end or rear end (looking the direction of rotation of emery wheel) along with the inertia of emery wheel, and the emery wheel upper shield at angle grinder 1 in this embodiment is equipped with casing 2, prevents that dust particulate matter from scattering everywhere, plays the effect of gathering together dust particulate matter, and the bottom of casing 2 is provided with the opening, and the opening is convenient to be placed on angle grinder 1's emery wheel with the processing plate, dust exhaust hole 21 has all been seted up at casing 2 front and back both ends, and the dust particulate matter that the emery wheel splashes is followed dust exhaust hole 21 and is siphoned away, no matter how the turning to of emery wheel.

In the second embodiment, on the basis of the first embodiment, the front half part of the housing 2 is detachably connected with the rear half part of the housing 2. The angle grinder 1 is easy to wear and tear after being used for a long time, the grinding wheel needs to be replaced frequently, the conventional integrated shell is narrow in operation space, and time and labor are wasted when the shell is replaced. This embodiment obtains bigger operating space through split the first half with casing 2 back half, and is easier when changing the emery wheel. The front half part of the shell 2 can be connected with the rear half part of the shell 2 through a buckle or a screw, and the convenient disassembly and the cost are lower.

In the third embodiment, on the basis of the first embodiment, the front half part of the housing 2 is rotatably connected with the rear half part of the housing 2 through a hinge. Compared with the second embodiment, the detachable connection is more stable, but the grinding wheel replacement is still slightly troublesome. The first half of this embodiment casing 2 passes through hinge rotation with casing 2 latter half and is connected, directly lifts casing 2's first half, alright expose the emery wheel, and is more convenient during the change, but casing 2's fastness is not good, combines embodiment two and three, can combine hinge rotation connection and buckle, when changing the emery wheel, buckle when opening earlier, then lift casing 2's first half, both conveniently change the emery wheel and guarantee the firm of casing.

In the fourth embodiment, on the basis of the first, second or third embodiment, a sealing strip is arranged at the joint of the front half part of the shell 2 and the rear half part of the shell 2. First half of casing 2 and the latter half of junction of casing 2 can produce the gap unavoidably, and dust particulate matter is probably escaped through the gap, and it can organize escaping of dust particulate matter to increase the sealing strip in gap department, and simultaneously when angle mill 1 uses, unavoidably there is the vibration, and first half of casing 2 and the laminating of the latter half of junction of casing 2 do not closely will send the noise because of the vibration, influence operating personnel, and the sealing strip can also play syllable-dividing and amortization's effect.

In the fifth embodiment, on the basis of the first, second, third or fourth embodiment, the upper end of the housing 2 is provided with an observation window. The inside behavior of casing 2 can be observed to the observation window, conveniently adjusts cutting depth or cutting length, improves the efficiency of operation. Meanwhile, the observation window can also observe the amount of dust particles during working, so that the size of the air suction volume is adjusted.

Sixth, based on the first, second, third, fourth or fifth embodiment, the outer wall of the housing 2 is coated with an anti-corrosive paint. The shell 2 is made of metal materials for durability and firmness, and the anti-corrosion paint can protect the shell 2 and prevent rusting and corrosion. As the anti-rust paint has multiple colors, the anti-rust paint can be coated into different colors according to the requirements of a production field so as to distinguish different equipment types and meet the 5S requirement of the production field.

Seventh, based on the first, second, third, fourth, fifth or sixth embodiment, the inner wall of the housing 2 is coated with a smooth coating. The inner wall of the shell is coated with the smooth coating, the smooth coating reduces the friction resistance of air flow, dust is not easy to adhere to the inner wall of the shell, and the dust collection effect is improved.

In the eighth embodiment, the dust exhaust holes 21 are circular holes on the basis of the first, second, third, fourth, fifth, sixth or seventh embodiments. The circular dust exhaust holes 21 have no edges and corners, which are beneficial to the flow of air flow, reduce the flow resistance and have no dead angles for storing dirt and dirt.

In a ninth embodiment, on the basis of the first, second, third, fourth, fifth, sixth, seventh or eighth embodiment, the dust suction duct is provided with an air volume adjusting valve. The dust particle content that the different article of cutting produced is different, adjusts the dust absorption amount of wind to suitable flow according to the dust absorption condition of reality, can guarantee good dust absorption effect, can not produce huge wind again and make an uproar. The opening or closing of the single dust suction device can be controlled, and other users of the central suction fan are not affected.

In a tenth embodiment, the dust suction duct is a transparent duct based on the first, second, third, fourth, fifth, sixth, seventh, eighth or ninth embodiment. The suction state of dust particulate matter is conveniently observed to transparent pipeline, conveniently finds the pile up of dust particulate matter again, when certain place of pipeline piles up more dust particulate matter, strikes or vibrates the pile up of pipeline and puts up, makes the dust raise, and easily suction eliminates and blocks up the hidden danger.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
