Description

Technical Field

[0001] This utility model relates to the technical field of concrete processing equipment, specifically a concrete aggregate batching machine. Background Technology

[0002] In the concrete production process, aggregates are the main component, and the accuracy of their proportions directly affects the strength, durability, and other properties of concrete.

[0003] However, existing concrete aggregate batching machines place various raw materials of aggregate separately inside the distribution bins, and then enter the collection box through the discharge pipe at the bottom of the distribution bin. When the weighing sensor at the bottom of the collection box senses that the raw materials collected inside the collection box have reached the preset value, it sends a signal to the PLC controller. The PLC controller controls the solenoid valve on the discharge pipe to close, and finally, through the motor, the collection box is reversed 180° to pour out the raw materials inside the collection box. Each collection box requires a drive motor, resulting in high manufacturing costs for the entire device.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing concrete aggregate batching machines. Utility Model Content

[0016] Please see Figure 1-4This utility model provides a technical solution: a concrete aggregate batching machine, including a collection bin 1, a distribution bin 2 fixedly connected to the top of the collection bin 1, a first discharge pipe 3 provided at the lower end of the distribution bin 2, a first electromagnetic valve 4 provided on the first discharge pipe 3, a column 5 fixed at the center of the top of the collection bin 1, a rotating shaft 9 rotatably mounted between the column 5 and the collection bin 1 via a bearing, a support plate 10 fixed to the outside of the rotating shaft 9, a weighing sensor 11 fixed to the top of the support plate 10, a collection box 12 fixed to the top of the weighing sensor 11, the collection box 12 being located directly below the first discharge pipe 3, and a drive mechanism provided inside the column 5.

[0017] The drive mechanism includes a servo motor 6, which is fixed at the bottom of the column 5. A first bevel gear 7 is fixed at the output end of the top of the servo motor 6. One side of the top of the first bevel gear 7 meshes with the bottom of one side of the second bevel gear 8. The end of the rotating shaft 9 passes through the side wall of the column 5 and is fixedly connected to the middle of one side of the second bevel gear 8. The material distribution bin 2, the first discharge pipe 3, the first solenoid valve 4, the second bevel gear 8, the rotating shaft 9, the support plate 10, the weighing sensor 11, and the collection box 12 are all distributed at equal angles about the central axis of the first bevel gear 7. When the first bevel gear 7 rotates, it can drive several second bevel gears 8, rotating shafts 9, support plates 10, weighing sensors 11, and collection boxes 12 to rotate simultaneously.

[0018] The bottom of the collection bin 1 is provided with a second discharge pipe 14, and a second solenoid valve 15 is provided on the second discharge pipe 14. The opening and closing of the second discharge pipe 14 can be controlled by the second solenoid valve 15.

[0019] The outer wall of the material collection bin 1 is equipped with a PLC controller 13, and the PLC controller 13 is electrically connected to the first solenoid valve 4, the servo motor 6, the weighing sensor 11, and the second solenoid valve 15. The PLC controller 13 can control the operation of the first solenoid valve 4, the servo motor 6, the weighing sensor 11, and the second solenoid valve 15.

[0020] A support rod 16 is fixed to the bottom of the outer side of the collection bin 1, and the support rod 16 is distributed at equal angles about the central axis of the collection bin 1. The design of the support rod 16 plays a supporting role for the entire device, so that the second discharge pipe 14 can be suspended, which is conducive to the discharge of raw materials inside the second discharge pipe 14.

[0021] Working principle: When using this concrete aggregate batching machine, the various raw materials of the aggregate are first loaded into several distribution bins 2. Then, the PLC controller 13 activates the first solenoid valve 4, opening the first discharge pipe 3. The raw materials inside the distribution bins 2 enter the collection box 12 through the first discharge pipe 3. When the weighing sensor 11 senses that the raw materials inside the collection box 12 have reached the preset value, the weighing sensor 11 transmits a signal to the PLC controller 13. The PLC controller 13 then controls the first solenoid valve 4 to close the first discharge pipe 3. After all the raw materials have been collected in the collection boxes 12, the PLC controller 13 starts the servo motor 6. The servo motor 6 drives the first bevel gear 7 to rotate. The first bevel gear 7 drives several second bevel gears 8, the rotating shaft 9, the support plate 10, the weighing sensor 11, and the collection boxes 12 to rotate simultaneously until all the collection boxes 12 rotate 180° simultaneously, so that all the raw materials inside the collection boxes 12 are discharged. Then, the servo motor 6 is started to rotate in the opposite direction, so that all the collection boxes 12 rotate 180° in the opposite direction simultaneously to reset and be ready for the next material collection.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
