Stone crushing device for municipal tunnel construction

Abstract

The invention discloses a stone crushing device for municipal tunnel construction. The stone crushing device for municipal tunnel construction comprises a machine body; a static jaw is fixedly connected to the interior of the machine body; a movable jaw is movably connected to the interior of the machine body; a discharging port is fixedly connected to the bottom of the machine body; a movable groove is formed in one side of the machine body; a buffer pad is fixedly connected to the inner side of the movable groove; and the inner side of the movable groove is movably connected with a transmission rod. According to the stone crushing device for municipal tunnel construction, the frame of a second filter screen is driven by the action of the movable jaw to collide and shake in a dust collector, dust on the second filter screen is continuously shaken off and collected, and therefore, the second filter screen is conveniently cleaned, the dust collector does not need to be manually disassembled for cleaning, and a fan is effectively protected; and meanwhile, the action of the movable jaw is converted into vibration to the discharging port, so that broken stones can be smoothly discharged, the inner wall of the discharging port can be cleaned, dust and small broken stones are prevented from being adhered to the inner wall of the discharging port, and the purpose of preventing the discharging port from being blocked is achieved.

Description

Technical field [0001] The present invention relates to the field of tunnel construction stone crushing technology, and is specifically a stone crushing device for municipal tunnel construction. Background technique [0002] The municipal tunnel is built in urban underground and is used as a tunnel that lay various municipal facilities. Due to further developing industries in the city, there is more and more underground pipelines for municipal facilities for municipal facilities, such as tap water, sewage, heating, hot water, gas, communication, power supply, etc. The development of the pipeline system requires a large number of municipal tunnels to fundamentally solve the problem of the management of underground pipeline systems of various municipal facilities. At the time of deposition, line, cable, cables, should have strict order and system to avoid excavation of streets and squares during maintenance and reconstruction. In the tunnel construction mining, a large amount of la...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stone crushing device for municipal tunnel construction, which uses the action of the movable jaw to drive the frame of the second filter screen to collide and vibrate inside the vacuum cleaner, continuously shaking off the second filter screen It is more convenient to clean the second filter. It does not need to be manually disassembled to clean the vacuum cleaner, which effectively protects the fan. At the same time, the movement of the movable jaw is transformed into vibration to the discharge port, so that the crushed stones can be discharged smoothly. At the same time It can also clean the inner wall of the discharge port, prevent dust and small gravel from adhering to the inner wall of the discharge port, and prevent the discharge port from being blocked. Excessive dust will affect the work of the fan and at the same time, because the second filter is located inside the vacuum cleaner, the cleaning of the second filter is also very inconvenient.
