Front frame for resonance crusher with skewed-arranged large beam and resonance crusher

Abstract

The invention relates to a front frame for a resonance crusher with a skewed-arranged large beam and a resonance crusher. The front frame comprises a front vertical plate, wherein an oil cylinder mounting supporting seat is fixedly connected to the other side of the front surface of the front vertical plate, and the oil cylinder mounting supporting seat is used for mounting a lifting oil cylinder of a crushing system counterweight; a counterweight left baffle and a counterweight right baffle are arranged at the lower end of the oil cylinder mounting supporting seat, and a second front wheel frame mounting plate is arranged under the counterweight left baffle and the counterweight right baffle; a second front wheel frame mounting hole is formed in the lower part of the second front wheel frame mounting plate, and the axis of the second front wheel frame mounting hole is higher than the axis of a first front wheel axle mounting flange hole; and a second front wheel frame is mounted in the second front wheel frame mounting hole, and a plurality of solid front wheels are mounted on the second front wheel frame. The front frame improves the coordination and reliability of the entire resonance crusher, provides sufficient support for the resonance crusher and balances the overall counter weight of the resonance crusher.

Description

Technical field [0001] The invention relates to a vehicle frame, in particular to a front frame used for an offset beam resonance crusher, and a resonance crusher using the front frame. Background technique [0002] Cement concrete refers to a general term for engineering composite materials that are integrated with water, such as cement, sand, and stone. It has a wide range of uses. Cement concrete paving is one of the main uses of hydraulic concrete. Roads paved with cement concrete follow As the service life increases, its pressure-bearing capacity and strength will be further weakened. That is, when the hydraulic (mud) concrete pavement can no longer bear the service function at the end of its service life, it needs to be treated to construct a new pavement structure. Resonance crushing technology uses the principle of resonance to adjust the vibration frequency of the hammer head to make it close to the natural frequency of the cement concrete pavement. By stimulating its re...

[0003] Chinese patent document CN206859028U records a cement pavement crushing vehicle. This type of crusher is the most common structural form of resonance crusher in the prior art. During the process, the front wheel on the side next to the hammer head is close to the edge of the road shoulder and has a width of nearly one meter. It is a dead corner that the hammer head cannot touch. This dead corner part often needs to be crushed manually and with an excavator, which seriously affects road construction. efficiency and quality
