Referring to fig. 1, the utility model provides an embodiment's entry driving machine boulder cleaning device, it includes dregs storehouse 30, row's thick liquid system and installs the whitewashing device in entry driving machine 10. The front end of the heading machine 10 is provided with a cutter head 20, and a muck bin 30 is positioned between the heading machine 10 and the cutter head 20. The slurry discharge system comprises a slurry discharge pipe 51, and one end of the slurry discharge pipe 51 is communicated with the residue soil bin 30. The guniting device comprises a telescopic nozzle 40, and a duct 11 capable of accommodating the nozzle 40 to extend out is arranged on the side wall of the heading machine 10. In this embodiment the lance 40 is secured in the heading machine 10 by means of an orifice device 12, the orifice device 12 being secured to the inner end of the tunnel 11, the orifice device 12 being provided with a through-hole through which the lance 40 can pass.

The nozzle 40 is connected to a slurry inlet system. The slurry inlet system comprises a slurry supply which is in communication with the nozzle 40 via a high pressure pump 53. The high-pressure pump 53 is connected with the slurry inlet end of the spray pipe 40 through the high-pressure rotary joint 42, so that the spray pipe 40 can rotate and stretch, the slurry can be sprayed out of the spray pipe 40 at a high speed, and the soil body can be cut efficiently. The slurry inlet system also comprises a slurry inlet pipe 52, one end of the slurry inlet pipe 52 is communicated with the muck bin 30, and the other end of the slurry inlet pipe 52 is connected with a slurry supply device. In the present embodiment, the stock discharge pipe 51 is located below the stock inlet pipe 52.

Further, a lance 40 is located at the bottom of the roadheader 10. The direction of extension of the lance 40 is at an acute angle to the direction of advancement of the heading machine 10. The extending end of the spray pipe 40 can extend to the front of the cutter head 20, a storage pit 70 is formed below the boulder 60, and the horizontal position of the storage pit 70 is lower than that of the heading machine 10, so that the boulder 60 does not affect the heading of the heading machine 10 after falling into the storage pit 70. In addition, because the slurry discharge pipe 51 is arranged below the slurry inlet pipe 52 in the embodiment, the mixed liquid of the slurry and the soil body can be directly discharged through the slurry discharge pipe 51 without passing through the slurry inlet pipe 52, and the mixed liquid is prevented from flowing back along the slurry inlet pipe 52. The slurry discharging end of the spray pipe 40 is provided with a spray head 41, the side wall and the end part of the spray head 41 are provided with spray holes, and the spray pipe 40 drives the spray head 41 to rotate when rotating, so that the construction efficiency of the storage pit 70 is improved.

The working principle of the utility model is as follows:

when the heading machine 10 encounters the boulder 60, the heading of the heading machine 10 is stopped in time, and the density is prepared to be (1.4-1.6) g/cm according to specific geological conditions³High density slurry of (a). The lance 40 is extended out of the heading machine through the tunnel 11 with the extended end of the lance 40 extending into the earth. At this time, the high-pressure pump 53 is started, the high-density slurry in the slurry supply device sequentially passes through the high-pressure pump 53 and the high-pressure rotary joint 42 to be connected into the spray pipe 40, the spray pipe 40 rotates at a high speed, the slurry is sprayed from the spray head 41 to cut the soil body, and meanwhile, the spray pipe 40 continues to extend, so that the spray head 41 is pushed forward to the soil body below the bottom of the boulder 60. The nozzle 41 is repeatedly advanced back and forth below the bottom of the boulder 60 by repeatedly extending and retracting the nozzle 40The row spraying pit making is carried out, the cut residue soil is mixed with the high-density slurry, and the mixed liquid enters the residue soil bin 30 and is discharged through the slurry discharge pipe 51. The size of the housing pit 70 is determined based on the amount of slag discharged, and the progress of manufacturing the housing pit 70 is determined. When the volume of the storage pit 70 reaches the required size, the spray pipe 40 is retracted into the heading machine, the cutter head driving system is started to drive the cutter head to rotate, the boulder 60 is shifted, the boulder 60 falls into the storage pit 70 under the action of self gravity, and obstacle removing work is completed.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited thereto, and various changes and modifications may be made without departing from the spirit of the invention.
