Example Embodiment

[0031] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0032] See Figure 1 to Figure 3 , The figure shows a preferred embodiment of the dust removal device of the present invention, the device is used for roadway boring equipment, such as roadheader 4, digging and anchoring machine, etc., this embodiment is applied to the roadheader 4 as an example, the dust removal device Be explained. As shown in the figure, the dust removal device at least includes a negative pressure air cylinder 3, a dust removal motor and a dust remover 6, as well as an air curtain mechanism 1 and a positive pressure air cylinder 2 connected in sequence.

[0033] Among them, the air curtain mechanism 1 is arranged on the inner wall of the roadway where the roadhea...

Abstract

The invention discloses roadway construction equipment and a dust removing device thereof. The dust removing device comprises a negative-pressure wind-cone, a dust removing fan, a dust remover, an air curtain mechanism and a positive-pressure wind-cone, wherein the air curtain mechanism is arranged on the roadway construction equipment or the roadway inner wall of roadway construction equipment operation; the air curtain mechanism is used for ejecting air current into a roadway to form a dust-blocking air curtain for isolating the control chamber of the roadway construction equipment from a tunneling work surface; the positive-pressure wind-cone is arranged on the roadway construction equipment or the roadway inner wall; the exhaust end of the positive-pressure wind-cone is arranged between the dust-blocking air curtain and the tunneling work surface; the exhaust end of the positive-pressure wind-cone points to the tunneling work surface; and the air sucking end of the negative-pressure wind-cone is arranged between the dust-blocking air curtain and the tunneling work surface. According to the dust removing device disclosed by the invention, air is supplied to the tunneling work surface through the positive-pressure wind-cone for blowing gas near the tunneling work surface away and lowering the gas concentration on the tunneling work surface, so that safety problems of explosion and the like possibly caused by the accumulation of gas on the tunneling work surface to a certain degree are avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to roadway excavation equipment and a dust removal device thereof. Background technique [0002] The roadheader is a comprehensive coal mining equipment that integrates the functions of cutting, loading, and walking. Since most of the excavation working faces are dry coal seams with very low water content, during the excavation process of the roadheader, there will be generated A large amount of dust, especially the amount of dust generated by rock roadway machine excavation, can be as high as 1000mg / m3 or more, and the operator of the roadheader is generally very close to the dust source, and the dust seriously endangers the physical and mental health of the operator. [0003] Patent No. CN200710015894 discloses "A Closed Dust Removal Method and Device for Road Header". The dust removal device in this patent includes an air curtain dust sealing device, a suction cylinder, a win...
