Description

Proportioning equipment is used in preparation of special cement of high-speed railway Technical Field The utility model relates to the field of cement preparation, in particular to proportioning equipment for preparing special cement for high-speed rail. Background In construction of high-speed railway infrastructure, cement is used as a key building material, the proportioning precision of the cement and sand directly influences the bearing capacity and durability of a high-speed railway track, and along with continuous improvement of engineering quality requirements of high-speed railway construction, the defects of a traditional cement preparation proportioning mode in precision control and automation degree are gradually revealed. When preparing the cement for the high-speed railway ballastless track, if the proportion of cement and grit deviates from design standard, can lead to concrete intensity to be insufficient or fracture, directly influence the security and the stability of high-speed railway operation, current equipment degree of automation is low, traditional ratio flow relies on manual operation material loading, measurement and mixing, can't realize automatic weighing and the ratio of material, in the construction of large-scale high-speed railway, not only consume a large amount of manpowers, still lead to the ratio mistake because of human error easily, delay construction progress, consequently, need design a special cement preparation of high-speed railway and use proportioning equipment to solve above problem. Disclosure of utility model The utility model aims to provide proportioning equipment for preparing special cement for high-speed rail, which is used for solving the problems set forth in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: the proportioning equipment for preparing the special cement for the high-speed rail comprises a protective box and a weighing box, wherein a supporting component for driving the protective box to lift is arranged on the outer side of the protective box, two feed hoppers are arranged on the top surface of the protective box, a baffle for blocking a discharge hole of the feed hopper is arranged on the top of the inner side of the protective box, a driving component for driving the baffle to transversely move is arranged on the inner side of the protective box, and perforations are formed in the surface of the baffle; The weighing box is located in the inner cavity of the protective box, weighing equipment for supporting the weighing box is installed at the bottom of the weighing box, a slope plate is installed in the weighing box, and a discharging component for blocking the side face of the weighing box is arranged on one side of the weighing box.
