Description

Technical Field

[0001] The utility model relates to the technical field of commercial concrete production, in particular to a precise batching system for commercial concrete production. Background Art

[0002] Commercial concrete, also known as ready-mixed concrete, refers to a pre-mixed, quality-certified concrete mixture that is sold to construction companies as a commodity and then transported to the construction site for pouring. Traditionally, the preparation of ready-mixed concrete relies on manual batching, where each material is weighed individually on a scale and then manually mixed. This manual batching method is not only labor-intensive but also inefficient, with the accuracy of the batching being particularly difficult to ensure. Existing concrete batching machines can automatically measure and batch sand, stone, cement, and other ingredients according to different concrete ratios, reducing labor intensity and improving efficiency. Furthermore, compared to traditional manual batching, they can also guarantee concrete quality to a certain extent. However, when the concrete batching machine is performing automatic batching, it controls the dosage of various concrete aggregates by stopping the conveyor belt. When the conveyor belt is stopped, the concrete aggregates on the conveyor belt will slide forward a distance due to inertia, causing the front-end aggregate to rush out of the conveyor belt and into the weighing hopper, resulting in excess ingredients and inaccurate dosage. The accuracy of ingredients is closely related to the performance of concrete. Therefore, the industry urgently needs to solve the problem of accurate batching in ready-mixed concrete production.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-6 The utility model provides a technical solution: a precise batching system for commercial concrete production, comprising a coarse aggregate silo 2, a fine aggregate silo 3, a cementitious material silo 4 for storing raw materials, and a conveying module 1 below the silo discharge port. Batching modules are provided at the discharge ports of the coarse aggregate silo 2, the fine aggregate silo 3, and the cementitious material silo 4. The batching module includes a discharge control module 5 connected to the discharge ports of the coarse aggregate silo 2, the fine aggregate silo 3, and the cementitious material silo 4, and a weighing module 6 directly below the discharge control module 5.

[0020] A bracket 7 is provided at the bottom of the weighing module 6, and the discharge control module 5 is mounted on the bracket 7 through a support 8;

[0021] The main body of the discharge control module 5 is a pyramidal cylinder without a top or bottom. The top of the pyramidal cylinder is connected to the discharge port of the silo. The bottom of the pyramidal cylinder is provided with a discharge control board 9 which slides on a slide rail. A first driving component 10 is installed on the discharge control board 9. A small discharge port is provided on the discharge control board 9. A discharge compensation plate 13 is provided at the small discharge port which slides on a slide rail. A third driving component 14 is installed on the discharge compensation plate 13.

[0022] The main body of the weighing module 6 is a rectangular cylinder without a top or bottom. A weighing plate 11 is slidably provided at the bottom of the rectangular cylinder via a slide rail. A second driving component 12 is installed on the weighing plate 11. A conical guide hopper (not shown) is provided below the rectangular cylinder so that the weighed material can fall completely onto the conveyor belt of the conveying module 1.

[0023] The first drive component 10, the second drive component 12, the third drive component 14 and the weighing plate 11 are connected to the external control center for electrical signals;

[0024] The first driving component 10 , the second driving component 12 and the third driving component 14 are a pneumatic telescopic rod, a hydraulic telescopic rod or an electric telescopic rod.

[0025] During use, the external control center controls the first driving component 10 to retract through the built-in batching system data, and pulls the discharge control plate 9 away from the bottom of the pyramid-shaped cylinder. The material in the silo falls on the weighing plate 11 of the weighing module 6. Due to the impact of the material, the weighing value of the weighing plate 11 will be greater than the actual weight of the material. After the weighing value of the weighing plate 11 reaches the set value of the batching system, the first driving component 10 extends to block the discharge control plate 9 to the bottom of the pyramid-shaped cylinder, and the material discharge is suspended. After the weighing value of the weighing plate 11 drops to a stable value, the batching system controls the third driving component 14 to retract, and removes the discharge compensation plate 13 to expose a small The material in the silo falls from the small discharge port onto the weighing plate 11 of the weighing module 6, and in the process, the discharge compensation plate 13 is gradually pushed, and the material flow rate is gradually reduced. After the weighing value of the weighing plate 11 reaches the set value of the batching system, the small discharge port is completely closed, and the weighing plate 11 is removed by the second driving component 12, so that the material falls onto the conveying module 1, completing the weighing and batching process. Since the flow rate of the small discharge port is small, the material impact at this time is greatly reduced, which effectively improves the weighing accuracy. By controlling the material discharge amount of the coarse aggregate silo 2, the fine aggregate silo 3, and the cementitious silo 4, the purpose of accurate batching is achieved.
