Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to a lump ore powder vibration screening device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in the ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Screening devices are needed to classify ore blocks and ore powders of different sizes during the mining process, but there are still some problems with the existing vibrating screening devices when they are used.

[0003] There is an existing ore screening device with a Chinese patent announcement number of CN211051942U, which includes a bottom plate, a conveyor belt and a screening box. The screening box is fixedly installed on the upper surface of the bottom plate, and the top of the screening box is connected to a feed hopper. The upper surface of the bottom plate and the side wall of the feed hopper are rotatably provided with a conveyor belt roller, and the two conveyor belt rollers are connected by a conveyor belt. The conveyor belt roller on the bottom plate is coaxially connected to a second driven wheel, and a motor is installed on the upper surface of the bottom plate. The output shaft of the motor is coaxially fixedly connected to a driving wheel, and the driving wheel is connected to the second driven wheel through a belt; when the ore screening device is used, the screening moves left and right to improve the screening efficiency, but because the position of the lower end collection box does not change, ores of different sizes will be mixed when unloading. At the same time, the existing screening device may be blocked after long-term use, which affects the screening efficiency. If it is not processed, it will lead to incomplete screening and affect the accuracy of classification.

[0004] Therefore, we propose a lump ore powder vibration screening device to solve the above problems. Utility Model Content
