The specific embodiment:
Road wheel 2 of the present invention adopts train wheel, and walking driving mechanism 3 adopts electronic walking driving mechanism, and other parts adopt common mining machinery processing method processing, and the connected mode assembling of by specification and Figure of description gets final product.Excavate cutter 12 to lay 2 along import department's symmetry ground in collection quarrel storehouse 10, adopt quarrel storehouse 17 interior with movable partition panel 18 every 3 branch storehouses.Movable partition panel 18 is because the effect of limited block 19 can only be done the rotation of 90 degree in adopting quarrel storehouse 17.Operating principle: road wheel operates on the rail, by the walking of walking drive mechanism.Rotating shaft 4 was rotated in motor 8 drove, interior rotating shaft 4 drives drill bit 5 and rotates, drill bit 5 begins to carry out the drilling operation in advance of tunnelling, the quarrel soil that drills through takes in the collection quarrel storehouse 10 with the drill bit spiral, motor 15 drives outer rotaring tube 9 and rotates, driving collection quarrel storehouse 10 and excavation cutter 12 rotates, the hole that excavation cutter 12 is bored with drill bit 5 is that excavate at the center, the quarrel soil that excavates enters by the import of adopting quarrel storehouse 17 and adopts in the quarrel storehouse 17, owing to adopt in the quarrel storehouse 17 and be provided with movable partition panel 18, to adopt the quarrel storehouse and be separated into 3 storehouses, rotate when excavating cutter 12, the muck removal mouth 22 of adopting quarrel storehouse 17 is in when making progress, owing to adopt in the quarrel storehouse limited block 19 be installed, movable partition panel is lived for 18 limited 19 grades at this moment, the quarrel soil that excavates enters each minute storehouse of adopting in the quarrel storehouse respectively, if do not establish movable partition panel 18 will adopt the quarrel storehouse be separated into 3 storehouses, when the muck removal mouth 22 of adopting quarrel storehouse 17 is in upwards, then all quarrel soil of adopting in the quarrel storehouse all drop on the bottom of adopting in the quarrel storehouse, the mouth that advances to be cut of then adopting bottom, quarrel storehouse just can't enter quarrel soil again, and excavating cutter work will be affected.Rotate when excavating cutter 12, the muck removal mouth 22 of adopting quarrel storehouse 17 is in when downward, movable partition panel 18 falls automatically, adopt the quarrel soil in the storehouse of each minute in the quarrel storehouse and all fall in the collection quarrel storehouse 10, fall quarrel soil in the collection quarrel storehouse 10 and fall the special in addition transportation down of collection quarrel storehouse by the muck removal hole 16 in collection quarrel storehouse again and be cut and transport the tunnel on the native tipping lorry by adopting quarrel storehouse muck removal mouth 22.Rail is that one section of one section limit laying is excavated on the limit forward, with prefabricated units the tunnel is carried out retaining wall simultaneously, thereby excavation speed is fast, and can excavate about 80m every day, and the time and labour saving is laborsaving.The present invention is specially adapted for the excavation of silt soil property.
