Pre-stored hopper processing and monitoring system and operation method of ready-mixed concrete mixer

Abstract

The invention relates to a pre-storage hopper processing and monitoring system and operation method of a ready-mixed concrete mixer. A pre-storage hopper is arranged under the hopper, and an automatic control opening and closing material inlet and an automatic control opening and closing discharge port are arranged on the upper and lower sides of the pre-storage hopper; the inner wall of the pre-storage hopper Set a negative pressure air duct, and set a dust removal device on its upper part; set a stress sensing plate at the lower part of the pre-storage hopper, and monitor the feeding amount and stocking amount in the pre-storage hopper through the stress sensing plate; set a humidity sensor at the lower part of the inner wall of the pre-storage hopper, The moisture content of concrete is monitored in real time, and a water inlet is set on the top of the pre-storage hopper. The present invention relates to a pre-storage hopper processing and monitoring system and operation method of a ready-mixed concrete mixer, which performs corresponding buffering of concrete to avoid the risk of material spilling out, and at the same time monitors the moisture content state of the concrete in the pre-storage hopper as well as the amount of stored material and the amount of material used in real time. Monitoring, reducing the waiting time of vehicles, improving transportation efficiency, has good economic and technical benefits.

Description

technical field [0001] The invention relates to a pre-storage hopper processing and monitoring system and operation method of a ready-mixed concrete mixer, which is suitable for adding a pre-storage hopper between a traditional mixer hopper and a transport vehicle for corresponding buffering, and monitoring the moisture content of concrete in the pre-storage hopper and feeding Quantity and inventory are monitored. Background technique [0002] The mixer is a kind of construction machinery, which is mainly used for mixing construction materials such as cement, sand and stone, and various dry powder mortars. This is a machine in which a shaft with blades rotates in a cylinder or tank to agitate and mix various ingredients into a mixture or consistency. There are many kinds of mixers, such as forced mixers, single-shaft mixers, twin-shaft mixers, etc. [0003] At present, the material of the traditional mixer directly enters the transport vehicle from the main engine, resulti...

AI Technical Summary

Problems solved by technology

[0003] At present, the material of the traditional mixer directly enters the transport vehicle from the main engine, resulting in the following outstanding problems: first, the production efficiency is slow, and the waiting time of the transport vehicle is long; The continuous impact is large; the third is that when the concrete is placed, there will be dry ash falling, which will cause dust pollution; the fourth is that the moisture content of the concrete in the hopper cannot be monitored in real time, and the poured concrete is often too dry and does not meet the quality requirements; five. It is because the stock and feeding amount of concrete in the hopper cannot be monitored, resulting in inaccurate statistics on the amount of concrete used
