Blanking adjustable discharging hopper device and concrete batch plant applying same

Abstract

The invention provides a blanking controllable discharging hopper device and concrete batch plant applying same. The discharging hopper device comprises a discharging hopper assembly (10) and a discharging valve assembly (20) connected below the discharging hopper assembly (10); wherein the discharging valve assembly (20) comprises a tubular valve body part (21) which is connected with a valve hopper assembly and is provided with a blanking channel, a valve part (23) which is arranged on the tubular valve body part (21) and comprises a rotating shaft (231) and a door sheet (232) connected onto the rotating shaft (231), as well as a driving part (24) which is connected to the end part of the rotating shaft (231) and drives the rotating shaft, so that the door sheet (232) can be selectively located at any position between full open position and full close position. The concrete batch plant of the invention comprises a stirring main machine and the discharging hopper device. The invention can conveniently realize control on lockage degree of discharging valve.

Description

technical field [0001] The invention relates to an adjustable discharging hopper device and concrete mixing equipment with the same. Background technique [0002] In the field of construction machinery, concrete mixing plants (buildings) are experiencing rapid development. Customers are increasingly pursuing product quality. On the one hand, they require higher mixing efficiency, and on the other hand, they pursue shorter mixing cycles. [0003] In the normal working cycle of the concrete mixing plant, there are many factors that affect the working cycle of the mixing plant, and one of the important factors is the unloading time of the mixing main engine. [0004] The mixing host is equipped with a discharge hopper device to control the discharge speed. The discharge door of the existing discharge hopper device on the mixing main engine has three states: fully open state, half open state and closed state. The unloading structure of the concrete mixing station is generally ...

AI Technical Summary

Problems solved by technology

However, if the unloading valve of the main engine is simply canceled and half-opened, the concrete will quickly enter the discharge hopper, and the concrete accumulated in the discharge hopper will also quickly enter the feed port of the mixer truck, which may cause the concrete to accumulate at the feed port, resulting in If the mixer truck is blocked, it will affect the unloading time

Therefore, the unloading hopper device with only three control states of half-open, fully open and closed cannot meet the actual unloading needs.
