Reinforced concrete crusher

Abstract

The invention discloses a reinforced concrete crusher comprising a crushing box, a discharging box and a crushing hammer, a motor frame is installed in the middle of the top end of the crushing box, asecond motor is installed on the inner side of the motor frame, a rotary disc is installed at the front end of a rotary shaft of the second motor, a rotating shaft is installed on the edge of the rotary disc, and a connecting rod is installed on the outer side of the rotating shaft; a first fixing frame is installed at the bottom end of the connecting rod, a long rod is installed at the bottom end of the first fixing frame, a limiting cylinder is arranged on the outer side of the long rod, and a connecting block and the crushing hammer are installed at the bottom end of the long rod. A supporting plate is arranged below the crushing hammer, a buffer pad is installed on the surface of the upper end of the supporting plate, a connecting plate is installed in the middle of the bottom end ofthe supporting plate, a second fixing frame is installed at the bottom end of the connecting plate, and a fixing block is installed on the inner side of the second fixing frame; a first motor is installed on the middle of the bottom end of the inner side of the crushing box, and the front end of a rotary shaft of the first motor is connected to the fixing block; the discharging box is arranged onthe right side of the crushing box. The reinforced concrete crusher is reasonable in structure, reinforced concrete can be crushed conveniently, and the crushing effect and the crushing efficiency areeffectively improved.

Description

technical field [0001] The invention relates to the technical field of concrete treatment, in particular to a pulverizer for reinforced concrete. Background technique [0002] Compared with concrete, the tensile strength of steel bars is very high, so people usually add reinforcement materials such as steel bars to the concrete to work together, the steel bars bear the tension, and the concrete bears the compressive stress; secondly, there is a good relationship between the steel bars and the concrete. Sometimes the surface of the steel bar is also processed into spaced ribs (called deformed steel bar) to improve the mechanical engagement between the concrete and the steel bar, but this is still not enough to transmit the tension between the steel bar and the concrete, although greatly It improves the firmness of reinforced concrete, but it also causes a lot of trouble when the building is demolished. After the steel bar is mixed with the concrete, the steel bar is stuck in ...

[0002] Compared with concrete, the tensile strength of steel bars is very high, so people usually add reinforcement materials such as steel bars to the concrete to work together, the steel bars bear the tension, and the concrete bears the compressive stress; secondly, there is a good relationship between the steel bars and the concrete. Sometimes the surface of the steel bar is also processed into spaced ribs (called deformed steel bar) to improve the mechanical engagement between the concrete and the steel bar, but this is still not enough to transmit the tension between the steel bar and the concrete, although greatly It improves the firmness of reinforced concrete, but it also causes a lot of trouble when the building is demolished. After the steel bar is mixed with the concrete, the steel bar is stuck in the concrete. When the building is demolished, the broken concrete is often firmly attached to the steel bar. It is difficult to crush and recycle. The traditional pulverizer is easy to be damaged by the steel bar. The crushing efficiency is slow. The traditional pulverizer is difficult to separate the steel bar from the concrete. The operation is complicated, and the device is not convenient for the steel bar when crushing the reinforced concrete Recycling, manual recycling of steel bars is time-consuming and labor-intensive, and the device is prone to a lot of dust after the concrete is broken, which affects the working environment
