Embodiment Construction

[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] Such as Figure 1 to Figure 5 As shown, a concrete side material recovery device includes a frame 1, a grinding barrel 2 is fixedly connected to the frame 1, and a fixed screw 21 and a moving screw 22 are rotatably connected in the grinding barrel 2, and the moving screw 22 is slidably arranged on the In the width direction of the grinding barrel 2, the outer diameters of the fixed screw 21 and the moving screw 22 gradually increase from one end to the other. The fixed screw 21 and the moving screw 22 are arranged in parallel and the axes of the two are located in the same horizontal plane. Between the fixed screw 21 and the moving screw 22, a grinding channel 23 for grinding concrete side material is formed. The wi...

Abstract

The invention provides a concrete offcut recycling device, belongs to the technical field of civil construction equipment and solves the problem that existing concrete milling is high in labor intensity. The concrete offcut recycling device comprises a rack, a milling barrel is fixedly connected on the rack, a fixed screw and a movable screw are rotatably connected in the milling barrel, a milling passage is formed between the fixed screw and the movable screw, the rack is rotatably connected with an incoming material conveying belt on the outer side of the milling barrel, an output end of the incoming material conveying belt is positioned above one end, larger in width, of the milling passage, first grid holes are formed in the incoming material conveying belt, the rack is connected with a first recycling passage below the incoming material conveying belt, and the rack is further rotatably connected with a first returning material conveying belt, a second returning material conveying belt and a third returning material conveying belt on the outer side of the milling barrel. The concrete offcut recycling device can automatically mill and recycle concrete offcut and is high in milling quality and efficiency.

Description

technical field [0001] The invention belongs to the technical field of civil construction equipment, and relates to a concrete scrap recovery device. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; water (may contain admixtures) and admixture) in a certain proportion, the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering. Inorganic cementitious materials such as cement, lime, and gypsum are mixed with water to make the concrete mixture plastic; and then through chemical and physical and chemical actions, it coagulates and hardens to produce strength. In the actual construction process, the concrete blocks removed from the wall can be recycled and reused, but due to the needs of transportation, st...
