A stone crushing device used in water conservancy projects

Abstract

The invention discloses a stone crushing device used in hydraulic engineering. The stone crushing device comprises a foundation rectangular base. The upper end of the foundation rectangular base is provided with a primary stone crushing box body and a secondary stone crushing roller device. The upper end of an inner cavity of the primary stone crushing box body is provided with a primary stone crushing device which is composed of a rectangular groove, a first fixing bearing, a sliding bearing, a rotating shaft, a roller, a driving device and a roller displacement adjusting device. The roller displacement adjusting device is composed of a rectangular opening, an adjusting rod, a connection rod, a first screw hole, a second screw hole and an adjusting screw rod. The secondary stone crushingroller device is composed of a supporting base, a second fixing bearing, a stone crushing roller, a stone crushing block, a circular discharge outlet, a rectangular through groove, a net sieve and a driving assembly. The lower end of the inner cavity of the primary stone crushing box body is provided with a feeding device which is composed of a circular feed inlet, an inclined supporting bottom plate, a screw rod and a first driving motor. The stone crushing device has the beneficial effects of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of hydraulic engineering equipment, in particular to a stone crushing device used in hydraulic engineering. Background technique [0002] Crushing devices are often needed in water conservancy projects. Traditional stone crushing devices can only perform simple crushing and then discharge directly. The efficiency of crushing stones is not only low but also the effect of crushing stones is not good. The size of the particles leads to a large number of unqualified particles, which not only reduces the working efficiency of the stone crushing device but also causes economic waste. Therefore, a stone crushing device used in water conservancy projects is now needed. Some primary crushing devices carry out the first crushing, and at the same time, the size of the crushed particles can be adjusted by adjusting the gap distance between the rollers, and the secondary crushing can also be carried out through the equipped crushi...

The efficiency of crushing stones is not only low but also the effect of crushing stones is not good. The size of the particles leads to a large number of unqualified particles, which not only reduces the working efficiency of the stone crushing device but also causes economic waste. Therefore, a stone crushing device used in water conservancy projects is now needed. Some primary crushing devices carry out the first crushing, and at the same time, the size of the crushed particles can be adjusted by adjusting the gap distance between the rollers, and the secondary crushing can also be carried out through the equipped crushing roller Particle screening, which not only improves the working efficiency of the stone crushing device, but also makes the crushing effect better, improves the pass rate, and reduces economic waste
