Description

A concrete production proportioning machine

Technical Field

The utility model relates to the technical field of concrete production, in particular to a concrete production proportioning machine.

Background Art

Concrete is made by mixing and stirring raw materials such as aggregates (sand, stone), cement, water, admixtures and additives in a certain proportion. During the concrete production process, a proportioning machine is needed to proportion the concrete raw materials before mixing them to avoid affecting the production quality of the concrete.

A concrete batching machine with publication number CN219788826U in the prior art is provided with a weighing sensor to sense the change of material weight inside the hopper, and then starts the first motor to drive the baffle to be inserted into the guide bin to reduce the flow and gradually close the guide bin. This structure can control the amount of material descending according to the change of hopper weight, thereby playing a role in accurately controlling the batching ratio.

Although the raw materials can be accurately proportioned, in actual use, the proportioned raw materials cannot be pre-processed, which will cause the materials discharged from the batching bin to fall on both sides of the lower hopper, and the raw materials cannot be evenly placed in the lower hopper. As a result, a long time is required to stir the raw materials in the future to evenly mix them together, which greatly reduces the production efficiency of the device, otherwise it will affect the quality of concrete production.

For this purpose, we propose a concrete production proportioning machine.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: a concrete production proportioning machine, including a support frame 1, a silo 2 is fixedly connected to the top of the support frame 1, a load-bearing sensor is generally arranged in the silo 2 to achieve the proportioning function of the concrete raw materials, and a partition 3 is arranged inside the silo 2 for isolating the concrete raw materials, a mixing hopper 5 is arranged below the silo 2, a fixed frame 4 is fixedly connected to the discharge end of the silo 2, and a material guide structure is arranged inside the fixed frame 4;

The material guiding structure includes a material guiding cover 6, which is rotatably connected to the bottom of the fixed frame 4, and a discharge port 11 is arranged at the eccentric position of the bottom of the material guiding cover 6. Inclined plates 7 are staggered and fixedly connected to both sides of the fixed frame 4, and a gear ring 8 is fixedly connected to the outer wall of the material guiding cover 6. A material guiding motor 9 is fixedly connected to the bottom of the bin body 2 through a connecting frame, and a gear 10 meshing with the gear ring 8 is fixedly connected to the output end of the material guiding motor 9;

When in use, the concrete raw materials are first poured into the chambers separated by the partitions 3 in the silo 2. When producing concrete, the valve at the bottom of the silo 2 is opened, and the concrete raw materials fall into the fixed frame 4, and then fall on the inclined plate 7. The inclined plate 7 can be used to preliminarily mix the raw materials from the two silos, and the mixed raw materials fall into the mixing hopper 5 through the discharge port 11. Then, the starting material guide motor 9 drives the gear 10 to rotate, which in turn drives the meshing gear ring 8 to rotate, thereby driving the material guide cover 6 to rotate, and then driving the discharge port 11 to rotate, so as to make the concrete raw materials fall evenly in the mixing hopper 5, and avoid the problem that the raw materials are piled up in one place, resulting in a long subsequent mixing time.

In order to achieve the mixing function of the proportioned concrete raw materials, a rotating rod 12 is fixedly connected at the center of the bottom of the material guide cover 6, and the bottom of the rotating rod 12 is rotatably connected to the bottom end of the mixing hopper 5. A plurality of stirring rods 13 are fixedly connected to the outer wall of the rotating rod 12 and located on one side of the mixing hopper 5. The material guide cover 6 is driven by the material guide motor 9 to rotate to pre-treat the concrete raw materials, and the rotating rod 12 is driven to rotate, thereby driving the stirring rod 13 to rotate in the mixing hopper 5, thereby achieving the mixing function of the concrete raw materials.

In order to ensure the complete discharge of the raw materials inside the mixing hopper 5, a scraper 17 is obliquely arranged on the inner side of the mixing hopper 5. The side wall of the scraper 17 is in contact with the inner side of the mixing hopper 5. The outer wall of the rotating rod 12 is fixedly connected to the scraper 17 through a connecting rod. When the material guide motor 9 drives the rotating rod 12 to rotate, it also drives the scraper 17 to rotate, thereby scraping off the raw materials adhering to the inner wall of the mixing hopper 5, avoiding the concrete raw materials from adhering to the inner wall of the mixing hopper 5, affecting the mix ratio of concrete, and thus reducing the production quality of concrete.

Among them, the fixed plate 14 is wrapped and fixedly connected to the outer wall of the mixing hopper 5, and the fixed support of the mixing hopper 5 is realized by the fixed plate 14. The four corners of the outer wall of the fixed plate 14 are respectively fixedly connected to the outer wall of the support frame 1. A pair of connecting plates 15 are fixedly connected to the bottom of the fixed plate 14. A conveying mechanism 16 is arranged between the connecting plates 15 and below the discharge end of the mixing hopper 5. The conveying mechanism 16 is mainly composed of a motor, a transmission roller and a conveyor belt.

Through the setting of the conveying mechanism 16, when the concrete raw materials are mixed, the valve at the bottom of the mixing hopper 5 is opened, and the mixed raw materials fall onto the conveyor belt of the conveying mechanism 16. Then the motor of the conveying mechanism 16 is started to drive the conveying roller to rotate, thereby driving the conveyor belt to transmit, so that the raw materials discharged from the mixing hopper 5 can be transported to subsequent equipment, thereby improving the practical performance of the device.

In order to prevent the raw materials from accumulating in the material guide cover 6 and being unable to be discharged, the bottom of the material guide cover 6 is tilted toward the discharge port 11, which is conducive to the raw materials falling into the material guide cover 6 to quickly slide toward the discharge port 11, thereby facilitating the rapid discharge of the raw materials and improving the practical performance of the device.
