Gravel screening device for hydraulic engineering construction

Abstract

The invention discloses a gravel screening device for hydraulic engineering construction. The gravel screening device comprises a first vertical rod, a second vertical rod, a supporting frame, a mounting frame and a screen, the screen is slidably mounted on the mounting frame through a sliding structure, a positioning structure is further mounted between the screen and the mounting frame, a first groove body is formed in the second vertical rod, a first rotating shaft is rotatably mounted in the first groove body, the two ends of the first rotating shaft are each fixedly provided with a mounting rod, an impact roller is rotationally mounted between the two mounting rods, a moving cavity and a mounting groove are formed in the second vertical rod, and the moving cavity communicates with the mounting groove and the first groove body at the same time. The device has the advantages that the impact roller can rotate clockwise by utilizing the movement of the screen, therefore, an impact effect can be generated on the screen after the impact roller is in contact with the screen, a removing effect can be achieved on gravels blocked on the screen, meanwhile, impact can further achieve a shattering effect on gravels blocked on screen, and screening is facilitated.

Description

technical field [0001] The invention relates to water conservancy projects, in particular to a sand and stone screening device for water conservancy project construction. Background technique [0002] Sand and gravel are very important materials in the construction of water conservancy projects. During the specific use process, the sand and gravel will be screened by the sand and gravel screening device, so as to obtain the sand and gravel of the required size for use; the existing sand and gravel screening device is fixed on the frame The screen on the body is composed of a fixed connection between the two. During the screening process, some sand and gravel are easily stuck on the screen, which affects the screening of sand and gravel. At the same time, it is necessary to manually remove the jammed sand and gravel. Affect sand screening efficiency. Contents of the invention [0003] The object of the present invention is to solve the problems raised in the background tec...
