Gravel processing device for bridge engineering construction by changing parabola accelerated crushing

Abstract

The invention discloses a gravel processing device for bridge engineering construction by changing parabola accelerated crushing. The device structurally comprises a shell, a feed port, a counter-attack plate, a uniform impact device, a rotor and a discharge port. According to the gravel processing device, through the cooperation of the changing parabola structure and a gradual change type groovestrip, the movement of changing the parabola track is carried out on the crushed stone which is subjected to single physical impact under the rotation effect, so that the counter-attack plate is prevented from being deformed and the crushing diameter of the crushed stone is prevented from being influenced due to the centralized abrasion of the counter-attack plate when the crushed stone impacts onthe impact plate; meanwhile, the situation that the crushed stone enhance the change of the throwing motion trail of the crushed stone under the rotary buckling action of a traditional striking plateis avoided, the uniform grinding structure is used for clamping the crushed stone with large impact during falling, the situation that the crushed stone directly collide with the rotor to acceleratethe abrasion degree of the rotor is avoided, the clamping shell is used for achieving the secondary splitting effect on the crushed stone, therefore, the crushed stones are crushed, and the crushed stones are prevented from rebounding and flying out when falling down under the action of gravity.

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
