Description

Technical Field

[0001] The utility model relates to the technical field of granular fertilizer batching equipment, in particular to automatic granular fertilizer batching and metering equipment. Background Art

[0002] Granular fertilizer automatic batching and metering equipment is an efficient and accurate automation equipment, which is widely used in the fertilizer production industry. The equipment can automatically complete the batching and metering of granular fertilizers, greatly improving production efficiency and product quality. Granular fertilizer automatic batching and metering equipment generally achieves the metering effect by controlling the flow rate and time of raw material delivery during use. In order to avoid failure of the metering structure, it is usually calibrated before use. Since the existing granular fertilizer automatic batching and metering equipment has multiple push-feed metering mechanisms, it is not easy to calibrate and has certain shortcomings. For this reason, we propose a granular fertilizer automatic batching and metering equipment. Utility Model Content

At the same time, by setting an audible and visual alarm, people can be reminded that the corresponding push-material metering mechanism has a large error. When in use, the user first aligns the weighing bucket with the positioning block of the weighing component and inserts it, and then controls the rotation motor of the rotating component to operate. The operating rotating motor can drive the rotating plate, the weighing component and the weighing bucket to rotate until the weighing bucket is directly below the push-material component to be calibrated. Subsequently, a certain amount of raw materials are pushed out by the push-material component, and the pushed raw materials can fall into the weighing bucket and be weighed by the weighing sensor, and converted into an output signal and transmitted to the external control device. When the weighed weight is significantly different from the expected weight, the external control device can control the audible and visual alarm to sound for calibration.
