Technical Field

The utility model relates to a material technical field is thrown to the concrete, and more specifically says, relates to a concrete mixing plant throws material device with accurate weighing.

Background

Along with the further increase of urban development, objective factors such as fluctuation of concrete raw materials, congestion of urban roads, weather change, increase of commercial concrete transport distance and the like can greatly affect the working performance of fresh concrete, for example, the slump loss of concrete is fast due to high temperature in summer, the concrete is easy to segregate due to low temperature in winter, and the like, and the working performance of commercial concrete is often required to be adjusted in real time on a construction site to meet the requirement of design regulation. However, most of the substances for adjusting the working performance of the concrete are liquids, such as water, organic liquids, inorganic liquids, salt solutions and other substances with flowing performance, the adding amount is large, and a container needs to be added from the tail of the concrete mixer truck manually, a construction site is often far away from a concrete mixing plant, the mixer truck does not have metering equipment, so that a series of problems that the liquid is inconvenient to carry, the liquid is not added timely, a climbing adding person with inaccurate liquid adding amount easily falls off due to the rotation of a tank body and the like exist, and the problems directly cause the loss of the concrete performance over time, increase the difficulty in controlling the concrete quality and create potential hidden dangers for personnel safety and engineering quality. Therefore, it is necessary to design a precise weighing and feeding device for commercial concrete mixing plant to solve the above problems. The patent document with the prior publication number of CN211389507U provides an accurate weighing and feeding device for a commercial concrete mixing plant, which indirectly pushes a piston to discharge liquid raw materials through a motor, and then combines a storage tank and a weighing platform to control the weight of the liquid raw materials, thereby completing accurate feeding. Although the device has more beneficial effects, the following problems still exist: the device promotes the piston through the bucket of exerting pressure, because the length that the bucket promoted the piston of exerting pressure is smaller, leads to the device to get the material efficiency lower, is unsuitable to get a large amount of materials. In view of this, we propose a precise weighing and feeding device for a concrete mixing plant.
