Handheld concrete crushing tool

Abstract

The invention belongs to the technical field of concrete crushing, and discloses a handheld concrete crushing tool. The handheld concrete crushing tool comprises an outer shell, wherein a motor is fixedly installed at the top of the rear side of the outer shell, the output end of the motor penetrates through the outer shell, extends into an inner cavity of the outer shell and is fixedly connected with a main shaft, the other end of the main shaft is fixedly connected with a cam, an outer extending edge is arranged on the periphery of the cam, and the bottom of the cam is in extrusion contact with a supporting wheel. According to the handheld concrete crushing tool, a worker holds a push-pull rod with hands, the tool is supported by matching a balancing weight at the other end, the worker does not need to press the body on the tool to directly feel the strong vibration feeling of the tool, so that the physical and psychological burden of the worker is reduced, moreover, when the crushing depth of the tool is adjusted, the worker does not need to apply pressure, the crushing depth can be adjusted by controlling a hydraulic rod to stretch out and draw back, the operation is convenient, and the working pressure of the worker is also reduced.

Description

technical field [0001] The invention belongs to the technical field of concrete crushing, in particular to a hand-held concrete crushing tool. Background technique [0002] Concrete crusher is suitable for metallurgy, mining, construction, chemical industry, water conservancy and railway departments. It is used for fine crushing and medium crushing of various ores and rocks with a compressive strength below 250Mpa. It has a large crushing ratio, uniform particle size of the finished product, and low power consumption. , Easy maintenance and so on. [0003] The above-mentioned crushers are large in size and not portable, and they cannot effectively impact and crush the concrete floor. In addition, the existing tools for crushing the concrete layer include impact drills and other tools, which have obvious disadvantages when used That is, in order to provide support for the impact drill, the staff will press part of the body on the tool.

Problems solved by technology

[0003] The above-mentioned crushers are large in size and not portable, and they cannot effectively impact and crush the concrete floor. In addition, the existing tools for crushing the concrete layer include impact drills and other tools, which have obvious disadvantages when used That is, in order to provide support for the impact drill, the staff will press part of the body on the tool. This practice has certain safety hazards, and after long-term use, its strong vibration will still cause great damage to the staff's body and endanger the staff. Secondly, the dust generated by the impact and crushing of impact drills pollutes the environment and endangers the health of the staff; thirdly, the drill bit of the impact drill is continuously used for a long time to heat up, which will easily cause the life of the device to be reduced; tools for improvement
