An easy-to-assemble material conveying protection device for paver

Abstract

A paving machine conveying protection device easy to assemble comprises a side plate, a side protection, a bottom frame for supporting a middle protection and the middle protection and is characterized in that side protection assembly extending blocks and a side protection assembly hole are formed in the side face of the side protection, side plate notches and a side plate assembly hole are formed in the side plate for installing the side protection, the side protection assembly extending blocks are connected with the side plate notches in a matched mode, and the side protection assembly hole is connected with the side plate assembly hole through bolts; a middle protection assembly extending block and a middle protection assembly hole are formed in the bottom of the middle protection, a bottom frame notch and a bottom frame assembly hole are formed in the bottom frame for supporting the middle protection, the middle protection assembly extending block is connected with the bottom frame notch in a matched mode, and the middle protection assembly hole is connected with the bottom frame assembly hole through bolts. The number of the fixing bolts is greatly decreased, needed assembly space is small, assembling and disassembling are quite convenient, and time and labor are saved.

Description

technical field [0001] The invention relates to an easy-to-assemble material feeding protection device for a paver, belonging to the technical field of engineering machinery. Background technique [0002] The main function of the paver conveying system is to transport the mixed material in the paver hopper to the material trough at the rear of the paver through the scraper conveying device. The main function of the material conveying protection set on the scraper conveyor chain is to ensure that the scraper conveyor chain is relatively accurate and has sufficient operating space, so that the conveyor chain can continuously transport the paving mixture without being stuck. result in chain damage. During the paving work, the amount of asphalt mixture changes cyclically, so the impact on the conveying protection is also constantly changing. This cyclical impact will cause the assembly bolts of the conveying protection to loosen or even fall off, resulting in failure of the con...

Problems solved by technology

During the paving work, the amount of asphalt mixture changes cyclically, so the impact on the conveying protection is also constantly changing. This cyclical impact will cause the assembly bolts of the conveying protection to loosen or even fall off, resulting in failure of the conveying system

like Figure 7 As shown, the currently widely used single feeding side protection is fixed by three or four bolts, and the protection of a single feeding is fixed by two bolts; this kind of fixing requires a large assembly space and is inconvenient to disassemble. And it takes a long time; it is difficult to repair and replace after the connecting bolts are loose or fall off, resulting in long-term construction stagnation
