Concrete hopper

Abstract

The invention discloses a concrete hopper which comprises a supporting frame, a storage hopper arranged on the supporting frame and an eccentric hopper door arranged at an outlet of the storage hopper. The eccentric hopper door comprises an eccentric shaft support arranged on the supporting frame, an eccentric shaft arranged on the eccentric shaft support, a triangular force transmission frame hinged to the eccentric shaft support through the eccentric shaft, a hopper door fixedly connected with one vertex of the triangular force transmission frame, and a handle fixedly connected with anothervertex of the triangular force transmission frame; one end of the eccentric shaft is connected with the eccentric shaft support, and the other end of the eccentric shaft is connected with the storagehopper; the eccentric shaft is located at the side, close to the hopper door, of the center of the storage hopper; and the hopper door rotates along the eccentric shaft under the action of the handlethrough the triangular force transmission frame so as to be opened and closed. The concrete hopper disclosed by the invention can be used for small-slump concrete pouring, and provides a larger adjustment space for concrete mixing proportion design.

Description

technical field [0001] The invention relates to the technical field of concrete hoppers, in particular to a concrete hopper. Background technique [0002] Concrete prefabricated components are widely used in the construction industry due to their quality assurance and fast construction speed. , Appearance quality, but its production process requires the use of concrete with a lower slump, but after the slump of the concrete is reduced, the construction process also changes accordingly, and the hopper mouth cannot be opened and the concrete cannot flow out freely if the ordinary hopper is used Problems such as the hopper mouth will affect the production progress of prefabricated components, and the slump will continue to be lost with the hydration reaction and water evaporation after concrete mixing, which will lead to the unusable concrete and waste of resources. Contents of the invention [0003] In order to solve the above problems, the object of the present invention i...
