Abstract
An adjustable dust adsorption head comprises a main dust adsorption head which is connected through a connector and a negative pressure air cylinder. The adjustable dust adsorption head is characterized in that side dust adsorption heads are respectively arranged on two sides of the main dust adsorption head, and the side dust adsorption heads are in rotation connection with the main dust adsorption head through a shaft sleeve and a matched pin shaft. According to the adjustable dust adsorption head, the side dust adsorption heads are added, the side dust adsorption heads and the main dust adsorption head are designed to be in rotation connection, the length of a dust adsorption opening is adjustable, the dust adsorption opening can extend into a working face of a concave part, the adjustable dust adsorption head can be adaptive to a complex dust adsorption working face, the problem that the dust adsorption head is replaced frequently according to working conditions is avoided, middle preparing working processes are reduced, working efficiency is improved, the materials of the dust adsorption head meets the requirements of safety regulations in a coal mine, and the adjustable dust adsorption head can be used in coal mine underground environment.
Description
Technical field
The utility model belongs to the dedusting technology field, relates to a kind of colliery arch support supported laneway wall except laying dust device-specific cleaner head, particularly a kind of adjustable cleaner head device.
Background technology
Coal mine roadway wall laying dust affects tunnel integrated environment health, has the potential safety hazard of secondary dust blast, and the special-purpose laying dust treatment facility safe and effective removing of energy tunnel, colliery laying dust reduces workman's workload.
At present, the colliery tunnel support form is more, comprise arch lane supporting, bolt-spary supports, arch support bolt-spary supports etc., the tunnel wall shape that various support forms form is different, integral body presents uneven situation, especially arch support bolt-spary supports, arch support can be given prominence to the shotcrete face, forms muscles and bones shape structure; According to the tunnel lithology, the arch support spacing is different, causes the planar condition of wall different.Traditional cleaner head is the strip nozzle structure, and during greater than the sunk part width, the cleaner head suction nozzle can't be close to the depression work plane when suction inlet length, causes pick-up performance to reduce; As change the cleaner head of little suction inlet length, though can address the above problem, reduce operating efficiency.
The utility model content
The purpose of this utility model is in order to design a kind of cleaner head of suitable colliery out-of-flatness work plane, to reduce the workman and frequently change the cleaner head link because work plane changes.
The technical solution of the utility model is, a kind of adjustable cleaner head, comprise the main cleaner head that is connected with negative pressure air duct by joint, key is: the both wings in main cleaner head arrange respectively the side cleaner head, and the side cleaner head is rotationally connected by axle sleeve, supporting bearing pin and the formation of main cleaner head.
Bearing pin junction at main cleaner head and side draught dirt also is equipped with back-moving spring.
Described axle sleeve comprises the collar bush that is arranged on main cleaner head and the side shaft cover that is arranged on the side cleaner head.
The place of being rotationally connected of described main cleaner head and side cleaner head also is provided with primary seal plate and side seal board.
Be respectively arranged with main hairbrush and side hairbrush on the lower surface of main cleaner head and side cleaner head.
The utility model is by increasing the side cleaner head, and side cleaner head and main cleaner head are designed to be rotationally connected, it is the suction port adjustable in length, can be deep into the position work plane that caves in, can adapt to complicated dust suction work plane, avoid frequently changing cleaner head because of operating mode, in the middle of reducing, the preparation link, increase work efficiency.The cleaner head material meets the safety regulations in coal mine requirement, can use at the colliery subsurface environment.

In accompanying drawing, 1 represents main cleaner head, and 2 represent the side cleaner head, and 3 represent back-moving spring, and 4 represent bearing pin, and 5 represent collar bush, and 6 represent the primary seal plate, and 7 represent side seal board, and 8 represent the side shaft cover, and 9 represent main hairbrush, and 10 represent the side hairbrush.
The specific embodiment
A kind of adjustable cleaner head comprises the main cleaner head 1 that is connected with negative pressure air duct by joint, and key is: the both wings in main cleaner head 1 arrange respectively side cleaner head 2, and side cleaner head 2 forms with main cleaner head 1 and is rotationally connected by axle sleeve, supporting bearing pin 4.
Bearing pin 4 junctions at main cleaner head 1 and side draught dirt 2 also are equipped with back-moving spring 3.
Described axle sleeve comprises that the collar bush 5 that is arranged on main cleaner head 1 and the side shaft that is arranged on side cleaner head 2 overlap 8.
Described main cleaner head 1 also is provided with primary seal plate 6 and side seal board 7 with the place of being rotationally connected of side cleaner head 2.
Be respectively arranged with main hairbrush 9 and side hairbrush 10 on the lower surface of main cleaner head 1 and side cleaner head 2.
The utility model in the specific implementation, as shown in Figure 1, the utility model structure is as follows: main cleaner head 1 both wings are used respectively bearing pin 4 installation side cleaner head 2, bearing pin 4 outside cover back-moving springs 3, the both sides extension of back-moving spring 3 overlaps with main cleaner head 1 and side cleaner head 2 upper surfaces respectively, and is in tensioned state.
Fig. 2 shown in 3, is main cleaner head 1 of the present utility model and side cleaner head 2 modular construction figure, and collar bush 5 and side shaft cover 8 are connected respectively at matrix separately, and the axle sleeve outside arranges respectively primary seal plate 6 and side seal board 7; Main hairbrush 9, side hairbrush 10 are inlayed respectively in the both sides of main cleaner head 1 and side cleaner head 2, form vacuum chamber separately.
During work, as be in smooth work plane situation, due to the effect of back-moving spring 3, side cleaner head 2 is in state shown in Figure 1 with main cleaner head 1, can effectively remove the plane laying dust.As run into when caving in work plane, greater than the depressed part bit length, the cleaner head middle part is unsettled due to cleaner head length, at this moment, operating personnel slightly firmly press cleaner head, and rotate by the side cleaner head 2 that turning cylinder connects both sides, as shown in Figure 4, main cleaner head 1 can reach depression position bottom dust suction.As from the depression work plane when moving on to smooth work plane, the side cleaner head 2 of both sides is lost the job in the face of its extruding force, only is subjected to the elastic restoring force of back-moving spring 3, makes cleaner head revert to state shown in Figure 1.
