Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a quantitative feeding device for concrete production and preparation. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of cementitious materials that bind aggregates into a whole. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion, and the resulting cement concrete is mixed and stirred. It is also called ordinary concrete. It is widely used in civil engineering. In the production and preparation of concrete, a feeding device is needed to feed and transport the materials.

[0003] According to the description of a quantitative feeding device for concrete production and preparation disclosed in the patent website (authorization announcement number: CN218659838U), "The utility model discloses a quantitative feeding device for concrete production and preparation, belonging to the technical field of concrete production, which includes a box body, the lower surface of the box body is fixedly connected to the upper surface of the base, the upper surface of the base is fixedly connected to the lower surface of the vibration structure, the support rod is fixedly connected with a positioning rod outside, one end of the positioning rod is clamped with one side of the connecting plate, the other side of the connecting plate is clamped with the side corresponding to the rotating plate, and the slide groove is slidably connected to the positioning rod; the quantitative feeding device for concrete production and preparation, by setting an adjustment structure, the feeding device adopts the quick cooperation between the rotating plate, the connecting plate and the supporting rod when transporting materials, so that the two partition plates will move up and down intermittently, and the amount of transported materials can be controlled to avoid excessive or insufficient concrete when mixing, which not only prevents material waste, but also improves subsequent work efficiency."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the telescopic rod will drive the guide plate to move synchronously when moving up and down, and the rear guide plate will drive the mesh plate to vibrate in the box, the feeding device can reduce the speed of the material falling and avoid the accumulation of materials during transportation. However, in actual use, since the guide plate is slidably connected to the groove, when the mesh plate moves up and down, it is easy for part of the material to pass through the groove and fall into the outside of the box, thereby causing material waste. This has certain limitations. Therefore, it is necessary to improve a quantitative feeding device for concrete production and preparation to solve the above problems. Utility Model Content
