High efficiency type drum agitator

Abstract

The invention discloses a high efficiency type drum agitator, which comprises a barrel, wherein the upper end of the barrel is provided with a charging opening; the lower end of the barrel is provided with a discharging opening; the inner wall of the barrel is provided with a connecting ring, which is located in an inner cavity of the barrel, through a first bearing; an agitating component is also arranged in the inner cavity of the barrel; the agitating component comprises a supporting rod and a connecting rod; the middle of the supporting rod is provided with a through opening which runs through the radial direction of the supporting rod; the connecting rod runs through the through opening; an elastic member which is located above the connecting rod is also arranged in the through opening; the supporting rod is also provided with an electromagnetic push rod; the outer wall of the barrel is connected with a gear ring in a sleeving manner; the high efficiency type drum agitator also comprises a driving component capable of driving the gear ring to rotate. When a raw material is more, the electromagnetic push rod is started to make a telescopic end of the electromagnetic push rod carry out repeated telescopic movement; in this way, the supporting rod can be controlled to carry out repeated up-and-down movement in the barrel; thus, the agitation coverage range of an agitating vane can be enlarged; an agitation dead angle is effectively avoided; the agitation of concrete is enabled to be more sufficient and uniform.

Description

technical field [0001] The invention relates to construction machinery, in particular to a concrete mixer. Background technique [0002] Concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. It is widely used in the field of construction. In industrial and civil construction, it has gradually changed from traditional manual mixing or sporadic mixing to the existing centralized management and supply. It can be seen that the centralized mixing of concrete is a major reform of concrete supply, and it has well realized the construction process. Specialization, commercialization and efficiency of concrete in China. To realize the concentrated mixing of concrete, the concrete mixing device is inseparable. Existing concrete mixing devices usually include a mixing tank and a mixing mechanism with stirring blades. In...

Problems solved by technology

Due to the fixed length of the stirring blade, even if it can mix the raw materials under the drive of the motor, there will still be areas in the mixing tank that the stirring blade cannot reach. These areas are actually dead angle areas. Uniformity and poor mixing effect will affect the quality of concrete
