Description

Technical Field

[0001] This utility model belongs to the field of automatic material distribution technology, specifically relating to an automatic material distribution control system. Background Technology

[0002] The material distribution vehicle is an important piece of equipment in the production of prestressed concrete pipe piles. It has a compact structure, is easy to operate, and is convenient to maintain. Its hopper capacity is generally slightly larger than the discharge capacity of the mixer, and it is usually advisable to load one batch of concrete. The vehicle speed is higher than that of the placing truck to reduce waiting time. Shock-absorbing springs are installed between the hopper and the frame to eliminate concrete segregation caused by vehicle vibration during travel, and to prevent damage to the hopper from vibration.

[0003] However, existing material distribution vehicles typically rely on operators to operate control valves to control the material flow rate and discharge time. During the discharge process, operators can also adjust the valve opening at any time according to actual needs to change the discharge speed and time. This method of material distribution not only fails to accurately control the amount of material discharged, but also places very high demands on the operator. Utility Model Content
