Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction joint roughening, and in particular to a construction joint roughening treatment machine. Background Technology
[0002] Construction joints are joints formed at the interface between new and old concrete during the concrete pouring process when construction is interrupted. If the surface of the joint is smooth, the new and old concrete cannot bond effectively, which will become a weak point in the structure. Construction joint roughening machines are devices that mechanically remove the laitance from the concrete surface, allowing the concrete to expose a rough surface, thereby increasing the bonding area of the concrete and improving the overall strength of the structure.
[0003] In traditional techniques, the collection of waste materials usually involves fixing with multiple screws and disassembling with special tools. It is not a quick-release design, and each disassembly and assembly requires unscrewing every screw. The same applies during installation, which consumes too much time and significantly reduces the overall efficiency of the operation. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a construction joint roughening machine, which aims to improve the problem of low disassembly and assembly efficiency caused by the cumbersome disassembly and assembly of traditional technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A construction joint roughening machine includes a baffle, a handle fixedly connected to the outside of the baffle, a damping rod fixedly connected to the outside of the baffle, a hollow cylinder fixedly connected to the outside of the damping rod, and a fixing mechanism fixedly connected to the outside of the hollow cylinder. The fixing mechanism includes a grooved column, which is fixedly connected to the outside of the hollow cylinder. A push rod is engaged inside the grooved column, and an auxiliary plate is slidably connected to the lower surface of the push rod. A first spring and a second spring are installed between the auxiliary plate and the grooved column.
[0006] Preferably, a waste collection box is fixedly connected to the outside of the push rod, and a cover plate is installed on the upper part of the waste collection box.
[0007] Preferably, a chisel is rotatably connected inside the hollow cylinder, and a track is rotatably connected outside the chisel.
[0008] Preferably, a rotating column is rotatably connected to the outside of the track, and a motor is fixedly connected to the outside of the rotating column, with the motor fixedly connected inside the hollow cylinder.
[0009] Preferably, the hollow cylinder is fixedly connected to a rubber protective cover.
[0010] Preferably, an M-shaped folding rod is fixedly connected inside the rubber protective cover.
[0011] Preferably, the hollow cylinder is externally fixedly connected with a grooved protective ring.
[0012] Preferably, a guide tube is fixedly connected inside the grooved protective ring, and the guide tube is fixedly connected outside the cover plate.
[0013] This utility model has the following beneficial effects: 1. In this utility model, by pushing the push rod forward to contact the auxiliary plate, the auxiliary plate squeezes the first spring and the second spring. When the front end of the push rod passes through the grooved column, the first spring and the second spring lift the auxiliary plate with their own reaction force. At the same time, the push rod is also lifted and tightly engaged with the grooved column. The waste residue collection box fixedly connected to the outside of the push rod also remains stationary. When it needs to be removed, the push rod can be pressed down, thus achieving the effect of quick installation and disassembly of the waste residue collection box.
[0014] 2. In this utility model, the operator holds the handle, and the motor drives the rotating column to rotate, which in turn drives the track to rotate. The track drives the chisel to rotate. During operation, the damping rod can greatly reduce the vibration caused by the rotational impact. The waste generated during construction enters the guide pipe through the grooved protective ring, and the guide pipe then sends the waste to the waste collection box, thus achieving the effect of collecting and treating the waste.
