Problems solved by technology

[0003] Many concrete laboratories in the prior art will be equipped with a small mixer for concrete testing. The raw materials need to be configured and weighed elsewhere, and then poured into the mixer. The efficiency of concrete raw material allocation is not high, and the mixing efficiency is also low. Not ideal, the entire mixer is not easy to clean, and residual concrete raw materials will affect the quality of the test

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0038] refer to figure 1 , a small-scale concrete trial mixing system for laboratories, including a pre-mixing box 1 located at the upper end of a base 9, a configuration table 2, a feeding auger 3 and a main mixing box 4, and concrete raw materials are arranged above the feed port of the pre-mixing box 1 The disposition table 2 is used for batching, and the discharge port of the pre-mixing box 1 is communicated with the feed port of the main mixing box 4 through the feeding auger 3 . Concrete raw materials enter the pre-mixing box 1 after batching through the configuration table 2, and then enter the main mixing box 4 through the feeding auger 3.

Abstract

The invention discloses a small concrete trial mixing system for a laboratory. The small concrete trial mixing system comprises a pre-stirring box, a batching table, a feeding spiral conveyor and a main stirring box; the batching table used for concrete raw material batching and weighing is arranged above a feed port of the pre-stirring box; the raw material enters the pre-stirring box after beingbatched by the batching table; and then a discharge port of the pre-stirring box is in communication with a feed port of the main stirring box through the feeding spiral conveyor. The small concretetrial mixing system can be used for trial mixing concrete in the laboratory, the raw material can be weighed through cooperation of the batching table and a charging barrel, the expected proportion raw material can be conveniently obtained, the concrete batching efficiency is improved, pre-mixing is carried out before raw material main mixing, the concrete stirring speed can be increased, and thebatching efficiency is high; and the whole system is convenient to clean and high in practicability.

Description

technical field [0001] The invention relates to the technical field of concrete production and research and development of mix proportions, in particular to a small-scale concrete trial mix system for laboratories. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. The combination of different types of raw materials and the same type of raw material combinations with different ratios will produce concrete with different qualities. Therefore, in order to adapt the concrete that meets the requirements, it is necessary to obtain high-quality concrete through adaptation tests without raw materials. [0003] Many concrete laboratories in the prior art will be equipped with a small mixer for concrete testing. The raw materials need to be configured an...
