Intelligent weighing and batching system for concrete aggregate

Abstract

The invention discloses an intelligent weighing and batching system for concrete aggregate. The system comprises a rack, a hopper fixedly arranged on the rack, a weighing hopper located under the hopper, a hanging mechanism used for hanging the weighing hopper on the rack and a weighing system sensor used for weighing. A movable hopper is arranged between the hopper and the weighing hopper, the movable hopper is slidably connected to the bottom end of the hopper in the vertical direction, an inner cavity of the movable hopper is communicated with an inner cavity of the hopper all the time, a discharging port is formed in the bottom end of the movable hopper, a driving mechanism used for driving the movable hopper to move is arranged between the movable hopper and the hopper, and a material blocking mechanism used for controlling the discharging port in the bottom end of the movable hopper to be opened and closed is arranged on the movable hopper. A valve plate is rotationally connected into a vertical part, a driving piece used for driving the valve plate to rotate is fixedly arranged on the weighing hopper, and when the valve plate is in the horizontal state, an inner cavity of the vertical part is separated. The system has the effects that impact on the weighing hopper is weakened, and inaccurate weighing results caused by too large impact are reduced.

Description

technical field [0001] The invention relates to the field of concrete aggregate weighing, in particular to an intelligent weighing and batching system for concrete aggregate. Background technique [0002] In the process of concrete production, cement is used as the cementing material to mix sand and gravel aggregates, water, admixtures and admixtures and other raw materials, and finally made into concrete, which is put into construction and production as building materials. As a kind of concrete processing equipment, concrete batching plant generally requires accurate proportioning of various materials during the production of concrete. In this process, concrete batching machines are usually used to weigh sand and gravel aggregates. [0003] The concrete aggregate weighing system in the related art usually includes a silo, a discharge opening at the bottom of the storage silo and a valve for controlling the opening and closing of the discharge opening, and also includes the ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the aggregate continuously falls into the weighing hopper at the discharge port of the hopper, and the accumulation height of the aggregate continues to rise. In order to ensure normal discharge, the discharge port and the The distance between the bottom walls of the weighing hopper is large, resulting in a high drop height of the aggregate when the hopper starts to discharge, which has a large impact on the weighing hopper, so there is a certain room for improvement
