Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a raw material crushing device for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, mixed with water in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete. It is widely used in civil engineering. In the existing technology, when processing concrete raw materials, a roller is usually used to roll the stones into uniform sizes.

[0003] However, the existing technology lacks the function of shaking screening. In actual use, after the stones are crushed, a screen is needed to screen out the stones of suitable size. The screen cannot shake internally, resulting in the stones being unable to fall out from above the screen, resulting in limitations in the existing technology.

[0004] In addition, the prior art lacks the function of rotating transportation. In actual use, some stones cannot be crushed into a uniform size during crushing, resulting in the need for secondary transportation and crushing. The prior art uses manual screening to pick them out, which is inefficient and has cumbersome steps, resulting in the inability to improve work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a raw material crushing device for concrete production to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A rotating conveying assembly is fixedly connected to one side of the housing, and the rotating motion assembly includes a fixed tube, a rotating rod and a guide piece. The inner bottom wall of the fixed tube is clamped with the rotating rod, and the outer surface of the rotating rod is fixedly connected with the guide piece;

[0010] The inner wall of the shell is fixedly connected with a rolling assembly, and the bottom end of the shell is fixedly connected with a supporting assembly.

[0015] Preferably, a feed port is fixedly connected to the top end of the shell, and a discharge port is fixedly connected to the bottom end of the shell.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A raw material crushing device for concrete production is provided with a first motor, a connecting block, a screen and a fixing frame. When in use, the connecting block is driven to move forward and backward by an external power supply of the first motor, and the connecting block drives the screen to move forward and backward. The crushed small stones fall onto the surface of the screen, and the shaking of the screen causes the small stones to fall into the device, while the stones larger than the screen opening will not fall into the device, thereby achieving the effect of shaking screening. The fixing frame is provided with a slope surface, so that the large stones can automatically roll to other positions for secondary transportation and crushing, thereby achieving the effect of guiding the large stones to the next process, avoiding the need for a screen to screen out stones of appropriate size after the stones are crushed, and the screen cannot shake inside, resulting in the inability of the stone to fall out from above the screen, resulting in limitations in the prior art.

[0018] 2. The raw material crushing device for concrete production is provided with a fixed pipe, a rotating rod, a guide plate, a material receiving pipe, a material discharging pipe and a second motor. When in use, the rotating rod is fixed by the fixed pipe, and the rotation of the rotating rod drives the guide plate to rotate. The guide plate rotates upward around the rotating rod, and the surface of the guide plate transports large stones upward for secondary rolling, thereby achieving the effect of transporting large stones for secondary rolling, and then the large stones are transmitted into the fixed pipe through the material receiving pipe, and the transported large stones go out from the material discharging pipe. The external power supply of the second motor drives the rotating rod to rotate, thereby achieving the effect of guiding the transportation of large stones, avoiding the situation that some stones cannot be rolled into a uniform size during rolling, resulting in the need for secondary transportation and rolling again. The existing technology uses manual screening to pick them out, which is inefficient and cumbersome, resulting in the inability to improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
