Problems solved by technology

Under certain working conditions, the maximum stress in some areas of the scraper exceeds the allowable stress of the scraper material, which in turn leads to strength failure
[0008] At present, most of the scraper conveyors used in coal mines are forged products made of alloy steel, which are heavy and have high frictional resistance; the scraper and the bottom plate of the groove side are subject to dynamic load and static pressure friction and wear, especially the extrusion wear of the scraper and the side of the groove Seriously affect the service life of the scraper conveyor
Moreover, due to the weight of the scraper made of alloy steel, the no-load of the scraper conveyor will also be too large, and more than 35% of the driving output power is used to do work to drive the scraper to move itself.
In order to meet the demand of the conveying volume, the output power of the driving device can only be increased. In this way, on the one hand, energy consumption will be increased and the transportation cost of the equipment will be increased; on the other hand, in order to increase the output power, the volume and Weight, while increasing the cost of equipment manufacturing, the overweight driving device will also cause the overall weight of the scraper conveyor to increase, increasing the working pressure of the hydraulic support; moreover, the excessive volume of the driving device also poses a greater challenge to the operating space of the workplace. High requirements reduce the flexibility of the scraper conveyor and increase the working limitations
[0009] In addition, the scraper is made of alloy steel. After materials such as coal mined by coal mining equipment collide with the scraper during the blanking process, the larger lumps of coal may be crushed, affecting The quality of coal, from another aspect to reduce the economic indicators of mining
[0010] To sum up, it can be seen that the above-mentioned defects in the existing scraper structure will limit the service life and performance of the whole scraper conveyor. Improve the structure of the existing scraper conveyor and become a skilled person in the field. Urgent problems

Abstract

The invention provides a material conveying device. The material conveying device comprises a material conveying groove, a material bearing and conveying assembly and a driving device; the material conveying groove comprises a walking track; the material bearing and conveying assembly comprises an annular chain, walking units, and strip-shaped elastic material bearing parts; the walking units arearranged on the chain at intervals and can be driven by the chain to move on the walking track in the material conveying direction; the walking units are provided with bottom faces close to the material conveying groove, top faces opposite to the bottom faces and side faces extending between the top faces and the bottom faces; the strip-shaped elastic material bearing parts are connected to the top faces and / or the side faces of the two adjacent walking units; and the chain can be driven by the driving device to circularly rotate relative to the material conveying groove in the material conveying direction. According to the material conveying device, the working state of the material conveying device can be improved, and the device stability and economic indexes are improved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, in particular to conveying equipment, in particular to a material conveying device. Background technique [0002] At present, scraper conveyors used in various industrial productions are the main transportation equipment for continuous transportation of granular materials. Especially used in mining fields such as coal mining, it can be well matched with mining equipment, and can be used as a moving support track for mining equipment, and can be adjusted and propelled under the drive of hydraulic supports. In particular, when the scraper conveyor is used in the current coal mining operation, the function of the scraper conveyor is not only as a carrier for coal and material transportation, but also as the running track of the shearer, so it has become an indispensable part of the modern coal mining process. main equipment. The scraper conveyor can keep running continuously, and ...
