Description

Technical Field

[0001] This invention relates to the field of intermediate bucket technology, specifically to an intermediate bucket gate, device, and control system. Background Technology

[0002] In the production processes of concrete batching plants, dry mortar plants, and precast component factories, the mixer needs a fixed amount of time to complete concrete mixing. If aggregate is conveyed via belt after the mixer unloads, a significant production downtime occurs, leading to low efficiency. Therefore, the industry generally adopts an intermediate silo pre-storage model, where metered sand and gravel are pre-stored in the intermediate silo while the mixer is operating. Once the mixer is ready, the aggregate is immediately added, achieving continuous production with mixing and material preparation simultaneously. The intermediate hopper gate, as a key control component between the intermediate silo and the mixer, directly determines production efficiency, material proportioning accuracy, and operational safety. However, existing intermediate hopper gates have the following drawbacks: 1. Existing intermediate hopper gates mostly use a single-cylinder or dual-cylinder shared drive structure, which is prone to uneven force distribution, resulting in incomplete gate closure and material leakage. Material leakage will cause extra materials to be mixed into the unmixed mixer, directly destroying the concrete mix ratio and causing product quality problems.

[0003] 2. Some technologies use a small gate design, which can improve the tightness of closure, but it will significantly reduce the material feeding speed, thus leading to a decrease in production efficiency.

[0004] 3. Most existing intermediate sluice gate structures adopt an integral design, which means that when a component is damaged, a completely new piece of equipment must be replaced, resulting in high maintenance costs and long maintenance time. Summary of the Invention

[0005] The purpose of this invention is to provide an intermediate hopper gate, device, and control system to solve the problems mentioned in the background art.

[0022] Working principle: When using this invention, the material is temporarily stored in the intermediate silo 3 via the conveyor 4. When the preset feeding time is reached, the control module 6 sends a command to the solenoid valve group 63. The solenoid valve group 63 controls the cylinder body 22 on the fixed seat 21 to retract. The cylinder body 22 drives the swing arm 23, which drives the rotating shaft 24 to deflect on the bearing 25. The gate body 26 on the rotating shaft 24 deflects and opens, allowing the material in the intermediate silo 3 to fall into the mixing station 5 below via the intermediate hopper assembly 1. The reinforcing plate 27 is used to improve the mechanical strength of the gate body 26. In the intermediate bucket assembly 1, the first side plate 11, the second side plate 12, and the extension plate 13 constitute the main body of the intermediate bucket. The first corner plate 14 and the second corner plate 15 are used to cooperate with the gate body 26 to achieve sealing. The fixing rod 16 is used to improve the mechanical strength of the intermediate bucket. The blocking plate 18 is used to install the seated bearing 25. The through hole 19 and the through groove 17 are used to avoid the rotating shaft 24. The control module 6 is used to control the operation of the intermediate bucket gate. The human-machine interaction module 61 is used for command input and data visualization. The power supply module 62 is used to supply power to the system, using 36V low-voltage power supply. The solenoid valve assembly 63 is used to control the cylinder, the data acquisition module 64 is used to collect the operating data of the intermediate hopper gate, the fault self-diagnosis unit 611 performs fault diagnosis based on preset thresholds. For example, in the case of minor faults such as low material level, a pop-up alarm is triggered without affecting production. In the case of serious faults such as low air pressure or gate not in position, the machine is immediately stopped and an alarm is triggered. The display unit 612 is used to display the gate status, air pressure, material level status, cumulative number of runs, and current fault code in real time. The operation unit 613 is used to switch operation modes, manually open and close the gate, set parameters, reset faults, and query historical faults. The alarm unit 614 is used to issue alarm reminders. The displacement sensor 641 is used to detect the cylinder extension and retraction stroke and determine whether the gate is in position based on the stroke data. The pressure sensor 642 is used to detect the air pressure, the material level sensor 643 is used to detect the material level, and the gate position sensor 644 is used to detect the gate opening and closing status. The signal from the displacement sensor 641 is used for double confirmation to avoid misjudgment caused by a single sensor failure. The installation position and installation method of the sensors are common knowledge in the field, so they will not be described in detail.
