Description

Technical Field:

[0001] The utility model relates to the technical field of mining, in particular to a crushed stone conveying device for mining. Background Art:

[0002] Mining is the technology and science of extracting mineral resources from within the earth's crust and on the earth's surface. Broadly speaking, mining also includes the extraction of coal and petroleum. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metal ores are important chemical raw materials and building materials. Mining is the technology and science of extracting mineral resources from within the earth's crust or on the earth's surface. Generally, it refers to the extraction of metal or non-metal ore deposits. Broadly speaking, mining also includes the extraction and beneficiation of coal and petroleum. Its essence is a process of selective collection and transportation of materials.

[0003] For example, a crushed stone conveying device for mining with the publication number of "CN210594049U" can avoid the direct fall of crushed stones through the receiving plate of the receiving device, provide primary material receiving, reduce the impact of crushed stones on the receiving box, and can not only treat the air but also filter the crushed stones. However, in the existing crushed stone conveying device for mining, during the process of conveying mined crushed stones, vibration can be provided to sort and filter the crushed stones to select more qualified crushed stone raw materials. However, the vibration provided by the vibrator is in a relatively small and high-frequency mode, which causes small pieces of crushed materials to be shaken out, but the conveying speed of the crushed stones is relatively slow. Therefore, the transmission efficiency of the crushed stones inside the receiving device is relatively low, and further the working efficiency of the crushed stone conveying device for mining is relatively low.

[0004] At the same time, in the existing crushed stone conveying device for mining, since the ore crushed stones collected inside the mining site are mixed with a certain amount of soil and other sundries, the soil sundries will have residual plant roots and vines that cannot be cleaned. The toughness of the plant roots and vines is relatively strong, and they are easy to wind around the rotating shaft of the conveyor belt and are also easy to wind and jam in the mechanical gaps of the crushed stone conveying device for mining, causing damage to the internal structure of the crushed stone conveying device, and making the use effect of the crushed stone conveying device for mining relatively poor. Summary of the Utility Model:

[0005] The purpose of the utility model is to provide a crushed stone conveying device for mining to solve the deficiencies of low use efficiency and poor use effect in the prior art.
