Cement hammering and recycling device for building

Abstract

The invention discloses a cement hammering and recycling device for a building. The cement hammering and recycling device comprises a base, wherein supporting plates are fixedly arranged on the left side and the right side of the top of the base, a top plate is fixedly arranged at the tops of the supporting plates, and a hammering chamber is fixedly arranged between the left supporting plate and the right supporting plate through a support; and the top of the top plate is fixedly provided with a lifting sliding rail, the left side of the lifting sliding rail is connected with a rack in a sliding mode through a sliding block, the bottom end of the rack is fixedly connected with a heavy hammer, the top of the top plate is rotationally connected with a second rotating shaft through a support,the second rotating shaft is fixedly provided with an incomplete gear, the top of the top plate is further fixedly provided with a second speed reducing motor, and the motor shaft at the front end ofthe second speed reducing motor is connected with the second rotating shaft through a belt transmission mechanism. According to the cement hammering and recycling device, the incomplete gear is meshed with the rack to drive the heavy hammer to move upwards, and when the incomplete gear is disengaged from the rack, the heavy hammer is rapidly descended under the action of gravity, and hammering and crushing are carried out on a cement block in the hammering chamber, and the heavy hammer is large in acting force and good in crushing effect.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a cement hammer crushing and recycling device for construction. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. Early lime and The mixture of volcanic ash is very similar to the modern lime pozzolanic cement. The concrete made of crushed stones is cemented with it. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. Due to the superiority of cement, the current construction Most of the objects use cement, which has high hardness and can resist erosion. However, it has also brought some problems. After the building is demolished, there will be a large number of cement blocks. These cement blocks are large a...

Problems solved by technology

[0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. Early lime and The mixture of volcanic ash is very similar to the modern lime pozzolanic cement. The concrete made of crushed stones is cemented with it. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. Due to the superiority of cement, the current construction Most of the objects use cement, which has high hardness and can resist erosion. However, it has also brought some problems. After the building is demolished, there will be a large number of cement blocks. These cement blocks are large and difficult to handle. If they are thrown away, they will cause waste. , become construction waste

[0003] Cement blocks can be reused after being crushed. The hardness of cement is high, and the crushing effect of ordinary crushing devices is not good. Larger, resulting in lower device life
