Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Example 1
As shown in fig. 1 and 3, it is a schematic structural diagram of a dust-proof excavator according to a preferred embodiment of the present invention. The dust-proof excavator in the embodiment comprises a suspension arm 109 and a crushing drill rod 108, wherein the crushing drill rod 108 is arranged at the front end of the suspension arm 109.
The front end of the boom 109 is also provided with a transparent dust cover 101 which surrounds the breaking rod 108. In this embodiment, the transparent dust cover 101 is made of reinforced glass fiber reinforced plastic, and the transparent dust cover 101 surrounds the breaking rod 108.
A dust suction filter 112 is further provided on the arm 109, the dust suction filter 112 is connected to the transparent dust cover 101 through the ventilation hose 102, and a water tank 110 is further provided on the arm 109.

In order to realize the cutoff and opening of water flow, the electromagnetic control valve 117 is electrically connected with a controller of the dustproof excavator through an electric control line, and the controller sends a control instruction to control the electromagnetic control valve 117 to be opened to realize the opening of the water flow after receiving a vibration signal, so that the spraying effect is realized.
An illumination device 107 is also provided in the transparent dust cover 101 to facilitate the excavating operation as much as when no treatment device is provided. The lighting device 107 is explosion-proof sealed, and a metal net is arranged at the front part of the lighting device 107 to prevent fragments from being collided and damaged.
The utility model discloses a dustproof excavator is when broken rock and road surface, and produced dust is at first through the one-level dust fall of shower head 111, and remaining small dust particle is clean basically through the air that exhausts behind dust absorption filter 112's second grade dust fall, can not produce the pollution to the air.
Two layers of filter screens are also arranged in the dust absorption filter 112: the first layer is a metal filter screen 103 which is responsible for filtering out large fragments; the second layer is a filter screen formed by non-woven fabric filter cotton, and can filter fine dust.
Furthermore, the illumination device 107 is provided in the transparent dust cover 101, so that the operation is convenient as the operation without processing device. In addition, the transparent dust cover 101, the water tank 110 and the dust absorption filter 106 are all arranged on the suspension arm 109, and the vibration generated by the crushing head 118 is not transmitted to the components, so that the service lives of the components can be well ensured.
Example 2
Fig. 2 is a partial schematic structural view of a second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the transparent dust cover 101 is replaced by a chain dust cover 201, the chain dust cover 201 mounted on the suspension arm 109 is formed by a metal chain or a metal bead which is surrounded into a circle, and the crushing rod 108 is arranged in the middle of the chain dust cover 201, so that the structure can ensure that the broken dust and broken bits do not splash, and can well resist the impact damage of broken bits.
The embodiment of this embodiment is the preferred embodiment of the present invention, not so limiting the protection scope of the present invention, if the first embodiment and the second embodiment can be combined to change the transparent dust cover into the chain dust cover, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
