concrete mixing system

Abstract

The invention provides a concrete stirring system. The concrete stirring system comprises a front-stage stirring device and a rear-stage stirring device. The rear-stage stirring device comprises a rear-stage stirring barrel, a central stirrer, a first planet stirrer, a second planet stirrer and a rear-stage driving mechanism. The central stirrer and the rear-stage stirring barrel are coaxially arranged, the central stirrer, the first planet stirrer and the second planet stirrer are arranged in parallel and are all connected with the rear-stage driving mechanism, the rear-stage driving mechanism drives the central stirrer to rotate around the axis of the rear-stage stirring barrel, and the rear-stage driving mechanism further drives the first planet stirrer to revolute around the axis of the rear-stage stirring barrel and rotate around the rotating axis of the first planet stirrer. The front-stage stirring device comprises a front-stage stirring barrel, a front-stage stirring shaft anda front-stage driving device. Concrete in a stirring container can be sufficiently stirred, no stirring dead space exists in the stirring process, and thus the uniformity of the final concrete can beeffectively guaranteed, building quality is ensured, stirring efficiency can be effectively improved, and feeding timeliness is ensured.

Description

technical field [0001] The invention relates to civil construction equipment, in particular to a concrete mixing system. Background technique [0002] Concrete is a commonly used building material. Concrete is formed by mixing sand, cement, gravel and water. Concrete mixing is realized by a mixer. The existing concrete mixer has the following defects: during the concrete mixing process, the The concrete near the stirring paddle can be fully stirred, but the concrete far away from the stirring paddle cannot be fully stirred, especially the coagulation near the side wall of the container of the mixer, often deposits, which seriously affects the quality of the concrete ; Moreover, the existing agitator directly pours sand, cement and crushed stone into the mixing container, then adds water and then stirs. In this way, due to the fact that sand, crushed stone and cement are originally separated, the mixing time is long and the efficiency is low. Low. [0003] Therefore, in ord...
