Description

Technical Field

[0001] The utility model relates to the technical field of mining, in particular to a multi-stage vibrating screen for mining. Background Art

[0002] Mining is the process of extracting useful minerals, metals, and gemstones from the crust of the Earth or other celestial bodies. This typically involves using various methods and techniques, such as mining, excavation, beneficiation, and extraction, to obtain the desired resources. Mining generates large quantities of rock, which requires screening using a vibrating screen. However, pouring the rock directly into the feed hopper mounted on the vibrating screen can easily cause blockage.

[0003] A Chinese patent discloses an ore screening device for mining (authorization announcement number CN207025805U). The patented technology mainly includes a chassis, the interior of the chassis is hollow, and a feed port is opened at the right side of the top surface of the chassis, and a lower hopper is welded at the feed port; a plurality of vibrating screens are arranged at intervals above and below, and the screening holes of the vibrating screens become smaller from top to bottom, and the vibrating screens are arranged tilted downward from right to left; a connecting seat is welded at the right end of the vibrating screen. Under the action of high-pressure water flow, the surface of the ore is washed. At the same time, since the ore rolls along the vibrating screen, the force effect of the high-pressure water flow is small, and the rolling speed of the entire ore is reduced. At this time, the screening time is correspondingly extended, thereby increasing the quality of vibratory screening. During the long-term vibration action, the slag on the surface of the ore falls off, and the water flow washes down the slag, thereby making the ore screening efficiency more outstanding.

[0004] However, this patent still has some shortcomings. During mining, a large amount of stone will be produced, and a vibrating screen is needed to screen the stone. However, directly pouring the stone into the feed hopper installed with the vibrating screen can easily cause the stone to clog the feed hopper. Therefore, those skilled in the art have provided a multi-stage vibrating screen for mining to solve the problems raised in the above background technology. Utility Model Content
