Concrete precast block production device

Abstract

The invention discloses a concrete precast block production device. The concrete precast block production device structurally comprises a rack, a stirring barrel, a hopper and a swinging-off device; a stirring shaft, stirring blades and a magnet strip are arranged in the stirring barrel; the swinging-off device is arranged on the top faces of the stirring blades and composed of a pressed plate, an upper elastic column, a lower biting clamp, a pushing frame and a shock mechanism; the upper elastic column and the lower biting clamp abut against the bottom end of the pressed plate and the interiors of the stirring blades together; the pushing frame is fixedly connected to the arching end of the lower biting clamp; and the shock mechanism is arranged at the tail ends of the outer sides of the stirring blades. According to the concrete precast block production device, the swinging-off device is arranged on the upper end faces of the stirring blades, so that concrete stirred to the high position collides with the pressed plate in advance when falling onto the stirring blades, the pressed plate is driven by the lower biting clamp to be further pressed downwards, the pressed plate is driven by the lower biting clamp and the upper elastic column to bounce upwards, the pressed plate can shake up and down when being collided by the concrete, the concrete is shaken off as soon as possible, and the situation that the concrete is solidified on the stirring blades, and consequently the concrete stirring effect is affected is avoided.

Description

technical field [0001] The invention relates to the field of concrete equipment, in particular to a production equipment for concrete prefabricated blocks. Background technique [0002] When the concrete prefabricated block is produced, the concrete is mixed and produced by the mixer, and then put into the prefabricated block grinding tool for molding; [0003] However, when the mixing equipment is working, the concrete is stirred through the outer end of the mixing blade. When the mixing blade rotates slowly, the concrete driven to the top by the rotation of the mixing blade falls because of insufficient speed, and hits the mixing blade of the next stage. Above all, the concrete on the surface layer will naturally flow back into the concrete material, and the concrete that hits the mixing blade first will easily stick to the mixing blade, which will affect the weight of the mixing blade and cause the stirring blade to shake when it rotates, which will affect the shaping of ...

[0003] However, when the mixing equipment is working, the concrete is stirred through the outer end of the mixing blade. When the mixing blade rotates slowly, the concrete driven to the top by the rotation of the mixing blade falls because of insufficient speed, and hits the mixing blade of the next stage. Above all, the concrete on the surface layer will naturally flow back into the concrete material, and the concrete that hits the mixing blade first will easily stick to the mixing blade, which will affect the weight of the mixing blade and cause the stirring blade to shake when it rotates, which will affect the shaping of the concrete. influences
