Efficient stone crushing device for water conservancy project

Abstract

The invention provides an efficient stone crushing device for a water conservancy project. The efficient stone crushing device comprises a first material box, a second material box, a lifting rolling part, at least one group of grinding rollers, a discharging pipe and a plurality of dust removal parts; the second material box is arranged above the first material box in a connected manner; the bottom of the second material box communicates with the first material box through a first open hole; a lifting motor and a feeding hole are arranged at the top of the second material box; a filter screen plate is horizontally and fixedly arranged in the second material box; the lifting rolling part is arranged in the first material box and the second material box and corresponds to the first open hole in position; a pressing plate is horizontally arranged at the bottom of the lifting rolling part; the pressing plate is driven by the lifting motor to vertically move up and down in the first material box and the second material box to roll broken stones on the filter screen plate; the at least one group of grinding rollers are arranged between the lifting rolling part and the inner side wall of the second material box in a manner of corresponding to the position of the feeding hole; the discharging pipe penetrates through the bottom of the first material box and is used for discharging the ground broken stones; and the plurality of dust removal parts are used for guiding water into the first material box and removing dust from the first material box and the second material box. The device disclosed by the invention can thoroughly crush broken stones and can automatically remove dust.

Description

technical field [0001] The invention relates to the technical field of stone crushing machinery, in particular to a high-efficiency stone crushing device used in water conservancy projects. Background technique [0002] Water conservancy engineering is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. It is also called water engineering. Water is an indispensable and precious resource for human production and life, but its natural existence The state is not exactly what a human needs. Only by building water conservancy projects can we control water flow, prevent floods, and adjust and distribute water to meet the needs of people's life and production for water resources. Blocks are crushed and utilized.

Problems solved by technology

[0003] After retrieval, Chinese Patent No. CN211937124U discloses a high-efficiency stone crushing device for water conservancy engineering, including a treatment tank, a feed inlet is opened on one side of the top of the treatment tank, and a pipeline is connected to the other side of the top of the treatment tank through an opening. One end of the pipeline is located at the top of the opening of the treatment tank, and a dust suction fan is installed through bolts, and a dust inlet is opened at the bottom of one side of the treatment tank. By setting a stone breaking motor, a stone breaking motor, a stone breaking roller and a stone breaking roller, The stone-breaking motors are used to drive the stone-breaking rollers to rotate the stones relatively to crush the stones, and then the stone-breaking motors are used to drive the stone-breaking rollers to rotate relatively to further crush the crushed stones. crushing, but this device is not effective for stone crushing, there are still many stones that are not completely crushed, and it is easy to generate more dust when crushing stones, and it is easy to cause dust when cleaning the dust Spread out
