Civil engineering sand sieving device

Abstract

The invention relates to a civil engineering sand sieving device. The civil engineering sand sieving device uses crosses formed by transverse rods and longitudinal rods for forming a sieving net structure, enables the transverse rods and the longitudinal rods to perform equal interval adjustment according to requirements through a transverse interval adjustment device and a longitudinal interval adjustment device, and simultaneously uses a locking function of a hydraulic telescopic rod in a hydraulic cylinder and a self-locking function of threads for achieving position locking after the equalinterval adjustment, enables the transverse rods and the longitudinal rods in the sieving net structure to be stable and reliable in the sieving process, is suitable for different grain diameters offine sand or sand stone, and avoids replacement of a sieving net, and meanwhile a power device drives the transverse rods and the longitudinal rods, which cooperate with one another, to separate whenhole blocking of the sieving net occurs or the sieving net needs to be cleaned, and then achieves cleaning effect by adjusting intervals. The civil engineering sand sieving device is simple to operateand ingenious in structure, avoids the replacement of the sieving net, and meanwhile can clean up the sieving net timely, and greatly improves sieving efficiency and quality.

Description

technical field [0001] The invention belongs to the technical field of sand screening devices, in particular to a sand screening device for civil engineering. Background technique [0002] Civil engineering refers to the general term for the science and technology of constructing various land engineering facilities. Civil engineering refers to various technical work such as survey, planning, design, construction, installation and maintenance for new construction, reconstruction or expansion of buildings, structures and related supporting facilities, etc. engineering entities. [0003] During the routine operation of civil engineering, it is often necessary to use sand with a qualified particle size, so as to meet the needs of the construction project. The existing sand screening device on the construction site can only screen out one kind of sand, but often due to the required sand particle size The difference between the screens makes the staff have to replace the screen,...

Problems solved by technology

[0003] During the routine operation of civil engineering, it is often necessary to use sand with a qualified particle size, so as to meet the needs of the construction project. The existing sand screening device on the construction site can only screen out one kind of sand, but often due to the required sand particle size The difference between the screens makes the staff have to replace the screen, which is complicated to operate, and the screening of sand is uneven, resulting in low work efficiency; and in the construction of dams in civil engineering, rock crushing is often used to obtain sand and gravel with different particle sizes. At this time, it is also necessary to replace the screen for screening sand and gravel. It is time-consuming and laborious to replace the screen, and the installation accuracy is difficult to grasp. At the same time, when the screen is blocked or stuck, not only for the The efficiency and quality of screening will be affected, and at the same time, the screen will be damaged to a certain extent, and the life of the screen will be reduced. Therefore, we urgently need a sand screening device for civil engineering to solve the above problems.
