Detailed Description
Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model belongs.
Referring to fig. 1 and 2, a ventilation device of an excavating and anchoring integrated machine provided in this embodiment includes: the device comprises an air supply device 3 and a dust removal device, wherein the air supply device 3 is arranged on a supporting platform 2, the dust removal device is arranged on a tunneling platform 1, and the tunneling platform 1 and the supporting platform 2 are separated by a dust curtain; the air outlet 5 of the air supply device 3 is positioned in the front area of the dust-proof curtain.
The dust collector is arranged on the tunneling platform 1 and is used for removing dust in the tunneling operation area, and a dust curtain is arranged between the tunneling operation area and the rear supporting area, so that a relatively independent space is formed in the tunneling operation area, the ventilation effect is poor, and the air supply device 3 is used for guiding clean air at the rear end of the equipment to the front and increasing the ventilation effect for the tunneling operation area.
Specifically, the chassis of the supporting platform 2 is of a hollow structure, an air supply channel is formed, the air supply device 3 is communicated with the air supply channel, and the air outlet 5 is positioned at the front end of the chassis. The air supply duct is formed by effectively utilizing the hollow space of the chassis, and the structure is simple.
The dust removing device comprises two dust removing fans 4 which are arranged on the tunneling platform 1, the front end of each dust removing fan is an air inlet, the rear end of each dust removing fan is an air outlet, and a sewage outlet is arranged at the bottom of each dust removing fan; a spraying device is arranged in the dust removal fan 4, and a water pipe interface for supplying water to the spraying device is arranged on the outer wall of the dust removal fan 4; the cutting arm of the heading machine is of a hollow structure, a plurality of dust collection openings are formed in the cutting arm, and an air duct communicated with the air inlet is formed in the rear end of the cutting arm. The cutting arm is of a hollow structure, forms an air inlet channel of the dust removal fan 4 and is communicated with an air inlet of the dust removal fan 4; during operation, the dust removal fan 4 is used for exhausting air, and a plurality of dust collection openings arranged on the cutting arm can collect dust, so that the dust collection efficiency is improved.
