Canal bottom lining machine with herringbone two-way concrete scraper mechanism

Abstract

The invention relates to a canal bottom lining machine with a herringbone two-way concrete scraper mechanism. The canal bottom lining machine with the herringbone two-way concrete scraper mechanism comprises a truss, a paving trolley, a conveying device, a discharging hopper, and two groups of the scraper mechanisms, wherein the paving trolley is arranged on the truss, the conveying device is arranged at the top of the truss, and the discharging hopper is arranged on the lower part of the output end of the conveying device; each scraper mechanism comprises a scraping plate, a hinge, an upper stop block and a lower stop block, the scraping plates are arranged at the bottom of the paving trolley through the hinges, the upper stop blocks are arranged on the upper parts outside the hinges, thelower stop blocks are arranged on the lower parts outside the hinges, and the upper stop blocks and the lower stop blocks can rotate and abut against each other according to the hinges; and the two groups of the scraper mechanisms are arranged in a herringbone mirror image mode, and the discharging hopper is arranged between the two groups of the scraper mechanisms. The canal bottom lining machine with the herringbone two-way concrete scraper mechanism has a simple overall structure, the operation is convenient, the construction efficiency is improved, and probability of mechanical failure and construction cost are reduced; and additional electric equipment and manual participation are not needed during paving, energy is saved, and labor intensity of construction personnel is reduced.

Description

technical field [0001] The invention relates to the field of concrete paving, in particular to a trench bottom lining machine with a herringbone bidirectional concrete scraper mechanism. Background technique [0002] During the construction of the canal bottom concrete, after the concrete is dropped from the conveying device to the working surface by the canal bottom concrete lining machine, a paving device is required to spread the accumulated concrete. [0003] Existing concrete paving devices are divided into two forms: electric screw paving devices and electric scraper paving devices. When paving canal bottom works, electric spiral paving devices are widely used at present. Electric spiral paving devices need to be equipped with special motors, reducers and other driving devices, which not only have complex structure, require electric drive, take up a lot of space, and have high costs. Moreover, there are problems such as difficulty in replacing wear parts and difficult...

AI Technical Summary

Problems solved by technology

When paving the canal bottom project, electric spiral paving devices are widely used at present. Electric spiral paving devices need to be equipped with special motors, reducers and other driving devices. Not only the structure is complex, electric drive is required, it takes up a lot of space, and the cost is high.

Moreover, there are problems such as difficulty in replacing worn parts and difficulty in maintenance in the later stage

[0004] Since the material distribution method is left and right reciprocating, when the paving scraper is used to pave the concrete, the direction of the paving slab must change with the change of the paving direction, so as to meet the purpose of always paving the concrete forward. Equipped with a power device for rotating the paving scraper, it not only has problems such as complex structure, high failure rate in use, and high construction cost

Moreover, because the electric scraper takes up a lot of space in the vertical direction, it is not suitable for use in large-scale canal bottom concrete lining projects.
