Device for bridge construction

Abstract

The invention discloses a device for bridge construction. The device comprises a machine seat and a stone crusher installed in the machine seat. The stone crusher is internally provided with a crushing portion, the inner top wall on the right side of the crushing portion is provided with a stone inlet in a penetrated manner, and the inner bottom wall on the left side of the crushing portion is internally provided with a movement guide cavity. The position, on the right side of the movement guide cavity, of the inner bottom wall of the crushing portion is internally provided with a lower discharging opening in a penetrated manner, and the top of the lower discharging opening is provided with a conical groove. The movement guide cavity is internally connected with a rising-landing slippage block extending upwards in a slippage fit manner, the extending segment at the top of the rising-landing slippage block stretches into the crushing portion, and the top, stretching into the crushing portion, of the rising-landing slippage block is provided with an arc surface extending in the lower right direction. The movement guide cavity under the bottom of the rising-landing slippage block is internally provided with first elastic pieces, the inner wall on the left side of the crushing portion is internally provided with a transfer groove, the inner top wall on the left side of the transfer groove is internally provided with a square groove in a connected manner, and right side of the transfer groove is internally provided with a first movement guide groove extending vertically in a penetrated manner. The device is simple in structure and convenient to operate, the crushing effect of hardened fertilizer is improved, the amount of labor is reduced, and stone crushing uniformity is improved.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge construction device. Background technique [0002] High-performance concrete is a new type of high-tech concrete. It has good durability, homogeneity, stability and economy when applied to bridges. It has certain strength and high impermeability. It can greatly improve the performance of ordinary concrete. Based on modern concrete technology. Crushed stone is the most used raw material in high-performance concrete, and the thickness of crushed stone plays a key role in the performance of high-performance concrete. The hammer crusher currently used in the market smashes the stone through the high-speed revolving hammer head, the stone particles are uneven, the hammer crusher is noisy, dusty, poor in stability, and the structure is complex and the operation is cumbersome. . Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
