Sand screening machine for water conservancy engineering

Abstract

The invention discloses a sand screening machine for water conservancy engineering, which comprises a fixed plate 1, a fixed plate 2, a horizontal plate, a support plate 1 and a stirring box. The bottom of the stirring box is provided with a discharge port 1, a fixed block, a motor, Feed inlet, rotating shaft, stirring rod 1, sand screen 1, through hole 1, vertical rod 1, stirring rod 2, vertical rod 2, vertical rod 3, sand sieving cylinder, mounting plate 1, mounting plate 2 and bolts, The fixed plate 1 and the fixed plate 2 are respectively horizontally inserted with the moving rod 1, the moving rod 2, the sand sieving tank, the sand sieving net 2, the storage plate, the cylinder, the piston rod and the limiter at the bottom of the discharge port 1. between the fixed plate 1 and the fixed plate 2, a sand sieve funnel with an upward opening, a support plate 2, a discharge port 2, a sand sieve net 3, an inverted L-shaped connecting plate and a sieve screen are arranged between the fixed plate 1 and the fixed plate 2. Sand net four, the bottoms of the fixed plate one and the fixed plate two are provided with damping devices. Compared with the prior art, the present invention has the advantages of good sand screening effect, easy cleaning and high stability.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering equipment, in particular to a sand screening machine for water conservancy engineering. Background technique [0002] Water conservancy engineering is a general term for various engineering constructions built to control, utilize and protect surface and underground water resources and the environment. Projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and rejuvenating profits are also called water projects. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. According to its service objects, it is divided into flood control projects, farml...

AI Technical Summary

Problems solved by technology

2. Water conservancy projects are generally large in scale, require large investment, complex technology and long construction period

When the sand screening machine in the prior art is in use, not only the sand screening effect is not good, but a large amount of gravel is mixed in the sand, which affects the use effect and quality of the sand, and the sand screening machine cannot be cleaned. A large amount of impurities have accumulated in the sand sieving machine, causing the sand sieving machine to be blocked, affecting the sand sieving effect, and making it inconvenient to use. At the same time, the stability of the sand sieving machine is not high, and the sand sieving machine is prone to sideslip during use, and its service life is low.
