Description

Technical Field

[0001] This utility model relates to the technical field of concrete equipment, specifically to a discharge device for concrete mixing equipment. Background Technology

[0002] In the field of construction engineering, concrete mixing equipment is an indispensable tool. Its performance directly affects the quality of concrete and construction efficiency. Traditional concrete mixing equipment discharge devices mostly adopt a fixed design, that is, the discharge port position is fixed and cannot be flexibly adjusted according to actual needs. This design has many inconveniences when using it. For example, when concrete needs to be transported to different locations, it is necessary to move the mixing equipment or transport vehicles, which not only increases the difficulty of operation and time costs, but may also have an adverse effect on the quality of concrete.

[0003] The patent publication number CN213769917U describes a method for flexibly adjusting the position of the discharge pipe by setting an adjustment mechanism and a connecting plate, thereby improving production efficiency to some extent. However, this patent only addresses the adjustment of the discharge pipe position and does not optimize aspects such as the stability of the mixing drum, the automation level of the discharge device, or space utilization. In actual use, insufficient stability of the mixing drum may lead to uneven mixing or equipment damage, while low automation of the discharge device increases the labor intensity of operators. Insufficient space utilization may result in a loose overall structure of the equipment, which is not conducive to transportation and installation. Therefore, we propose a discharge device for concrete mixing equipment. Utility Model Content
