Description

Technical Field

[0001] The present application relates to the technical field of aggregate scales, and in particular to a concrete aggregate calibration device. Background Art

[0002] Concrete aggregates are needed in the concrete processing process. Concrete aggregates refer to loose granular materials that play a role as a skeleton or filler in concrete. Aggregate scales are key equipment in concrete production. When concrete is produced, the specific weight of the required aggregates and powders is calculated through the corresponding mix ratio before mixing and production. The accuracy of the aggregate scale weighing directly affects the production quality of concrete. Therefore, we need to calibrate the batching scale bucket weekly, monthly, or even annually to ensure the accuracy of the concrete batching scale weighing.

[0003] At present, the calibration of aggregate scales is generally to place weights directly in the scale bucket or on the edge of the scale bucket, and read the corresponding values ​​to determine the accuracy of the aggregate scale. However, placing weights in the hopper or on the edge of the hopper will bring certain operating difficulties to the operator: 1. Due to the narrow edge of the hopper, the weights placed on the edge are likely to fall and injure the operator, posing a major safety hazard; 2. If the weights are placed in the hopper, the hopper has a small entry and exit space and the weight of the weights themselves, it is time-consuming and laborious to put them in or take them out, making the calibration process more troublesome and reducing the safety and convenience of calibration. Utility Model Content

[0004] In order to improve the convenience during calibration, the present application provides a concrete aggregate calibration weighing device.

[0005] The present application provides a concrete aggregate weighing device, which adopts the following technical solution:

[0006] A concrete aggregate weighing device comprises a plurality of weighing devices arranged at intervals along the periphery of a weighing bucket, wherein the weighing devices comprise:

[0007] A suspension rod, the suspension rod being rotatably arranged on the weighing bucket;

[0008] A placing frame, which is arranged on the suspension rod and is used for placing weights;

[0009] A positioning mechanism is arranged on the weighing bucket and is used to position the placement frame; during calibration, the positioning mechanism unlocks the placement frame and causes the placement frame to rotate under the action of gravity and causes the suspension rod to be set vertically downward; after the calibration is completed, the placement frame is rotated to abut against the weighing bucket and is positioned by the positioning mechanism.

[0010] By adopting the above technical solution, when calibration is required, the positioning mechanism is unlocked, and the placement frame rotates downward under the action of gravity so that the boom is positioned in a vertical state, and then the weights are placed in the placement frame for calibration. After the calibration is completed, the weights are taken out, and the placement frame is rotated to rest against the scale bucket. The positioning mechanism positions the placement frame, which reduces the risk of weights falling and improves the convenience of putting in or taking out weights, thereby improving the safety and convenience during calibration, so that the calibration device can be calibrated at any time, and subsequent calibration leaves do not need to be installed and unlocked again. At the same time, the placement frame is positioned by the positioning mechanism, which improves the stability of the calibration device when the scale bucket is in use, thereby further improving the stability during subsequent calibration, and further improving the safety and convenience of calibration.

[0019] By adopting the above technical solution, when the positioning buckle plate locks the placement frame, the movable plate is pressed against the lower surface of the limit plate under the action of the elastic member, thereby preventing the positioning buckle plate from rotating away from the placement frame. When unlocking is required, the rotation of the shaft drives the limit plate to squeeze the movable plate, so that the limit plate rotates to the bottom of the movable plate, so that the positioning buckle plate is unlocked, the shaft is released and the limit plate rotates and presses against the lower surface of the movable plate for positioning, thereby preventing the positioning buckle plate from rotating; when locking is required, the rotation of the shaft drives the positioning buckle plate and the limit plate to rotate, and when the positioning buckle plate is against the scale bucket, the limit plate presses against the upper surface of the movable plate for positioning, thereby preventing the positioning buckle plate from rotating away from the placement frame, thereby realizing unlocking and locking of the placement frame, thereby improving the convenience during calibration.

After the connecting shaft is plugged into the fixing ring, the pushing member pushes the movable shaft to plug and cooperate with the connecting shaft and enables the connecting shaft to be rotatably installed on the fixing ring and the movable shaft.

[0031] By adopting the above technical solution, the connecting screw is turned away from the connecting shaft, and the hanging rod drives the connecting shaft to push the movable shaft away from the fixed ring and close to the connecting screw, so that the connecting shaft is disengaged from the fixed ring, and then the connecting shaft moves back to disengage from the movable shaft, thereby realizing disassembly from the placement frame; when connection is required, the connecting shaft is plugged and installed on the fixed ring, and the connecting screw is turned to push the movable shaft close to the connecting shaft, so that the connecting shaft and the movable shaft are plugged and matched, thereby realizing the disassembly and rotational connection between the hanging rod and the placement frame.
