Small excavation crusher for underground roadway of coal mine

Abstract

The invention discloses a small excavation crusher for an underground roadway of a coal mine. The small excavation crusher for the underground roadway of the coal mine comprises a vehicle body, wherein a conveying device is arranged in the vehicle body, and an excavation crushing arm is arranged at the top of the vehicle body; through cooperation of a triggering device and a clamping device, whenthe orientation of a bucket device deviates from the orientation of the conveying device, an energy storage device is driven through the conveying device to rotate, energy stored in the energy storagedevice is increased, and meanwhile, the bucket device acts, and is enabled to temporarily store deposits; through a shifting device, energy transmission can be automatically interrupted after the energy stored in the energy storage device is enough; through cooperation of the bucket device, the triggering device and the clamping device, when the orientation of the bucket device and the orientation of the conveying device are the same, the energy in the energy storage device is automatically released, and meanwhile, the bucket device generates corresponding action, the deposits stored in the bucket device can be pushed into the conveying device conveniently, and then the deposits in the side front part of the bucket device can be cleaned conveniently, so that the time and labor are saved,and the practicability of the excavation crusher is improved.

Description

technical field [0001] The invention relates to the field of small excavating crushers, in particular to a small excavating crusher for coal mine underground roadways. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the ground surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. During the mining process of underground coal mines, it is necessary to use a small excavating crusher in the coal mine underground roadway to excavate, clean up and remove the accumulations in the roadway. broken. [0003] The existing small excavator crusher for coal mine underground roadway is improved on the basis of traditional small excavator. The specific improvement is to install a breaker on the excavator arm and install a transmission mec...

Problems solved by technology

[0003] The existing small excavator crusher for coal mine underground roadway is improved on the basis of traditional small excavator. The specific improvement is to install a breaker on the excavator arm and install a transmission mechanism on the car body. The bottom end of the transmission mechanism is fixed. A bucket is installed. When in use, first use the breaker to break the accumulation, and then use the excavation bucket to push the accumulation into the bucket, and then the accumulation moves up along the bucket and enters the transmission mechanism under the push of the excavation bucket. And convey upwards, so as to realize the excavation, cleaning and crushing of the accumulations in the roadway. However, the orientation of the bucket is always consistent with the orientation of the vehicle body. When there is accumulation on the side of the bucket, it is necessary to use the excavating arm and The cooperation of the bucket pushes the accumulation in front of the side of the bucket gradually to the front of the bucket, and then the accumulation can be pushed to the transmission mechanism, which is time-consuming and laborious. Therefore, it is urgent to design a small mining crusher for coal mine underground roadway.
