Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, this mining scraping plate electric hydraulic excavating machine includes the large arm in excavator upper frame
4, the sub-arm 2 being connect with the large arm 4, rotary oil cylinder 3 built in sub-arm 2, the forearm 1 that the sub-arm 2 connects；Forearm 1
Connection bucket 12 is controlled by telescopic oil cylinder.Large arm 4 and sub-arm 2 and forearm 1 constitute three joint arms work structuring of the invention.
It further include being disposed through the intracavitary scraper plate conveyer belt 8 of chassis of dredging machine, 8 front end of scraper plate conveyer belt is equipped with shovel
Bucket 14.
Further, it is connected between the large arm 4 and sub-arm 2 by telescopic oil cylinder.It realizes between sub-arm 2 and large arm 4
Flexible operation.
Further, rotary oil cylinder 3 built in the sub-arm 2.Rotary oil cylinder 3 can realize ± 90 degree of rotations, meet 360 degree of nothings
Obstacle is broken to be excavated.
Further, it is connected between the sub-arm 2 and forearm 1 by telescopic oil cylinder.It realizes between forearm 1 and sub-arm 4
Flexible operation.
Further, the scraper plate conveyer belt 8 passes through the control driving of hydraulic motor 7.Scraper plate transport is realized by hydraulic motor 7
With 8 operating.
Further, the scraper bowl 14 is controlled by the bucket cylinder 13 being set on chassis of dredging machine.Pass through bucket cylinder 13
