A broken stone processing equipment for bridge engineering construction which is changed from throwing to accelerated crushing

Abstract

The invention discloses a crushing stone processing equipment for bridge engineering construction which is changed from throwing to accelerated crushing. Beneficial effects: the present invention utilizes the combination of the re-throwing structure and the gradual groove bar to change the parabolic trajectory of the crushed stones that are subjected to a single physical impact under the action of rotation, so as to avoid causing them to Concentrated wear leads to the deformation of the impact plate and affects the crushing diameter of the gravel. At the same time, it avoids the change of its parabolic trajectory under the action of the traditional impact plate rotation and buckle. The impacted gravel is jammed when it falls, so as to avoid its direct impact with the rotor, and accelerate the wear of the rotor, and use the jamming to split the gravel again, so as to realize the crushing effect on the gravel and avoid its impact on the rotor. While falling due to gravity, there is a rebound effect and it flies out.

Description

technical field [0001] The field of bridge construction equipment of the present invention, more precisely, is a broken stone processing equipment for bridge engineering construction which is changed from throwing to accelerated crushing. Background technique [0002] In the process of road and bridge construction, the process is relatively complicated, and the bearing load of the bridge needs to be strictly controlled during construction. Therefore, improving the quality of bridge construction is the first priority of the construction party during construction, because most of them use concrete during construction. Therefore, the concrete needs to be manufactured in strict accordance with the requirements of bridge construction during processing. When making concrete, it is necessary to crush and process the crushed stones of a certain specification to avoid the appearance of cracks on the surface after the pouring is completed. There are raised stones. [0003] Bridge con...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a crushing equipment for bridge engineering construction that is changed from throwing to accelerated crushing, so as to solve the problem of the prior art that the crushing is achieved through a simple physical action of the impact type. The crushing of the stone is squeezed and stroked under the rotation of the rotor, so that the crushed stone hits the counterattack plate in a parabolic trajectory under the centrifugal action, because the center of the circle and the movement track are the same, the surface of the counterattack plate is prone to concentrated One place is severely worn, which leads to the deformation of the impact plate, which affects the crushing diameter of the gravel. It is large and has an impact effect, so the gravel will be directly stuck on the surface of the rotor due to the action of gravity, thereby increasing the wear of the rotor, and it may bounce out from the feeding port. deficiency of necessary injury
