Laneway repair machine

Abstract

The invention discloses a laneway repair machine which comprises a portal frame (1), a rotating oil cylinder (2), a large arm seat (3), a large arm (4), a large arm oil cylinder (5), a small arm oil cylinder (6), a small arm (8), a breaking hammer oil cylinder (9), a breaking hammer (11), a bucket oil cylinder (12), a link mechanism (13), a quick connector (14) and a bucket or hydraulic shear (15), wherein the small arm oil cylinder (6) is positioned below the large arm (4); the large arm oil cylinder (5) is arranged in a cavity of the large arm (4); the rear end of the breaking hammer (11) is provided with a slide block or idler wheel (7); the upper part of the breaking hammer oil cylinder (9) is provided with a sliding groove (10); the slide block or idler wheel (7) can move in the sliding groove (10); one end of the breaking hammer oil cylinder (9) is movably connected with the breaking hammer (11), and the other end is movably connected with the small arm (8); the quick connector (14) is arranged on the small arm (8); the link mechanism (13) is connected with the quick connector (14); and two grooves positioned on the quick connector (14) are closed and opened through a control mechanism, so that the fast replacement of the bucket (15) and the hydraulic shear (15) can be realized. The laneway repair machine disclosed by the invention has the advantages of realizing that breaking, shearing and assembling functions are integrated into a whole, simplifying the procedure of the mutual replacement of multiple equipment, reducing the construction auxiliary time and increasing the work efficiency of laneway excavation.

Description

technical field [0001] The invention relates to a backhoe loader, in particular to a roadway repairing machine with multiple functions such as digging, crushing and pruning. Background technique [0002] In mine construction, after drilling and firing, most of the traditional backhoe loaders are used to excavate and load the muck to the conveying mechanism (scraper transportation, mine truck transportation) for output, but in actual work, it is often encountered that the muck contains Irregular large rocks and irregular rocks will appear around the roadway during the blasting process. In order not to damage the conveying mechanism and improve the working efficiency of the conveying mechanism, most of the mine construction will replace the bucket with a breaker to deal with the large rocks and the surrounding roadway.

Problems solved by technology

[0002] In mine construction, after drilling and firing, most of the traditional backhoe loaders are used to excavate and load the muck to the conveying mechanism (scraper transportation, mine truck transportation) for output, but in actual work, it is often encountered that the muck contains Irregular large rocks and irregular rocks will appear around the roadway during the blasting process. In order not to damage the conveying mechanism and improve the working efficiency of the conveying mechanism, most of the mine construction will replace the bucket with a breaker to deal with the large rocks and the surrounding roadway. Irregular rocks are broken, and the replacement method is to manually disassemble a lot of screws before disassembling the bucket from the backhoe loader, and then install the breaker with fastening screws. This disassembly and replacement method is used in construction. There are the following problems: First, due to construction needs, the bucket and breaker are replaced frequently, which not only takes a long time to replace, but also is troublesome to disassemble and assemble, and the labor intensity is high, thus reducing the construction efficiency and increasing the construction cost. Hidden dangers; the second is that for objects such as steel bars, anchor rods, and cement blocks that appear around the roadway, the breaker cannot be trimmed. Usually, it is repaired manually by using a special trimmer. Not only is the trimming efficiency low, the labor intensity is high, and safety accidents are prone to occur

Therefore, the existing backhoe loaders have problems such as less functions, low construction efficiency, and weak applicability.
