Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and more specifically, to a weighing device for concrete processing. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; cement concrete obtained by mixing with water in a certain proportion, also known as ordinary concrete, is widely used in civil engineering. In the process of concrete processing, a variety of raw materials are used, so weighing devices are needed to weigh the amount of materials.

[0003] However, there are various types of weighing devices in the prior art. For example, utility model patent CN216050219U relates to an aggregate weighing device for convenient loading concrete processing. The utility model is provided with a fixed box, a warning light, and a measuring box inside the fixed box. The bottom of the inner wall of the measuring box is provided with two fixed grooves, and the insides of the two fixed grooves are slidably connected to the driving blocks. The surfaces of the two driving blocks are fixedly connected to the mounting rods. The surface of the mounting rods is rotatably sleeved with a connecting plate. The other end of the connecting plate is fixedly connected to a baffle. The two baffles slide inside the measuring box, and the inner wall of the measuring box is rotatably connected to the rotating shaft and the rotating rod through bearings. The utility model uses the material to squeeze the mounting plate, so that the interference block on the surface of the mounting plate triggers the control switch. Since the control switch is electrically connected to the warning light, when the control switch is triggered, the warning light lights up, reminding the amount of material, thereby achieving the weighing function and avoiding errors.

[0004] Although this weighing equipment can effectively weigh materials and remind the amount of materials, it is exposed to the external environment. When a large amount of materials are directly put into the equipment, the concrete will produce a large impact force during the falling process, and a large amount of dust will appear. If it is not protected, it will pollute the working environment. At the same time, the impact force will also cause damage to the equipment. In order to avoid this phenomenon, it is very necessary to design a weighing device for concrete processing. Utility Model Content

In the process of weighing the concrete material, the dust cover 6 that can move up and down is lowered, so that the dust cover 6 is close to the corresponding weighing bucket 4 and close to it, but does not squeeze the weighing bucket 4, and the open weighing bucket 4 is protected from dust. Then the material is loaded and placed in the feeding hopper 12, and then the rotating motor 9 is started. The rotating motor 9 provides driving force to the spiral conveying shaft 10, so that the spiral conveying shaft 10 drives the spiral blade 11 to move together, and the spiral blade 11 is used to rotate and push the material, and the material is slowly and continuously pushed from the conveying cylinder 8 into the weighing bucket 4, thereby avoiding a large impact force caused by a large amount of material being put into the bucket at one time, and a large amount of dust being generated. At the same time, the flying dust can be blocked to ensure that the working environment is not polluted.
