Rock crushing and heading machine

Abstract

The invention discloses a rock crushing and heading machine. The rock crushing and heading machine structurally comprises a crushing and shoveling cap, a suspension arm column block, a pressing rod pushing and stretching machine base, a conveying belt supporting table, a control chamber base, a front surrounding plate and a bucket discharging groove. The rock crushing and heading machine has the advantages that the suspension arm column block is matched with the pressing rod pushing and stretching machine base, a combined crossed bevel overturning traction effect is formed by a compressed spring wire piston rod and a hydraulic cylinder frame groove in the bottom end of the rack, it is guaranteed that an overturning plate pressure-bearing seat and a frame strip overturning plate frame are buffered through a reserved groove of crossed acting force, a swinging piston pushing effect is formed by upper and lower pressure-bearing elastic pressing thrust, the integrated linkage of the whole rack is improved, the double-station telescopic alternate movement track flexible adjusting effect is achieved, the heading distance is stable in the rock crushing process, the rack protection space issufficient, the consistent operation effect of inertia buffering and rigid boosting is facilitated, continuous propelling of the heading machine is improved, and the stable quarrying and material collecting engineering progress for continuous chiseling through is formed.

Description

technical field [0001] The invention relates to a rock crushing tunneling machine, which belongs to the field of mechanical equipment. Background technique [0002] The rock layer in the mine is often accompanied by high-density stone such as granite, which is convenient for people to carve into handicrafts and made into materials for building foundations, ensuring the rigid processing effect of mine rock crushing and excavation equipment, and the stability of the project progress, improving rock processing The efficiency of collection, the disadvantages of current technologies that need to be optimized are: [0003] During the rock crushing process, there will be counter-point collision between the rebound pressure of the chisel frame and the propulsion impact force, which will cause the rigid impact force of the rock surface and the recoil force to seriously damage the steel plate of the entire frame boom, resulting in the shaft being completely damaged. The phenomenon of...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a rock crushing tunneling machine to solve the counterpoint collision between the rebound pressure of the chisel frame and the propulsion impact force during the rock crushing process, which will cause the rigidity of the rock surface. The impact force and recoil force seriously damage the steel plate of the whole frame boom, resulting in the phenomenon that the shaft rod and the shell frame are completely concave, resulting in the phenomenon that the lock pin is stuck during the lifting process of the frame, which affects the entire chisel pressure. The swing pressure and inertial force of the claws, and the lack of linkage rock formation pressure, cause the rock formation to slip off the gravel, and cannot continue to break and excavate large rock formation materials, which reduces the working efficiency of the equipment and interferes with the progress of the project.
