Embodiment Construction

[0019] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0020] like figure 1 and figure 2 As shown, according to the embodiment of the present invention, the mixing device includes a mixing drum 10 and a feeding hopper 30 . The stirring port of the mixing drum 10 is provided with a material guiding tube 20; The material guiding cylinder 20 is sealed with a sealing member 40 , and the outer wall of the sealing member 40 is provided with a spiral groove 41 that rotates in the same direction as the stirring blades in the mixing drum 10 .

[0021] During the rotation of the mixing drum 10, the concrete will be squeezed and tumbled. At this time, under the action of the spiral groove 41 of the sealing member 40 and the mixing blade of the mixing drum 10 th...

Abstract

The invention provides a stirring apparatus and a concrete mixer comprising the same. The stirring apparatus comprises a stirring drum (10) and a feed hopper (30) arranged at the stirring mouth of the stirring drum (10); the stirring mouth of the stirring drum (10) is provided with a material guiding canister (20); the stirring drum (10) is arranged in a rotatable manner relative to the feed hopper (30); a sealing element (40) is arranged on the feed hopper (30) and is cooperated with the material guiding canister (20) in a sealed manner; and the outer wall of the sealing element (40) is provided with a helical groove (41) with a turning direction same to the turning direction of stirring blades in the stirring drum (10). The stirring apparatus provided by the invention is capable of solving the problem that concrete is easy to overflow during stirring in the prior art.

Description

technical field [0001] The invention relates to the field of concrete mixing machinery, in particular to a mixing device and a concrete mixer truck including the mixing device. Background technique [0002] In the process of transporting concrete by concrete mixer truck, in order to prevent segregation or consolidation of concrete, the mixing drum needs to be continuously rotated so that the concrete is mixed and stirred during the lifting and turning process to keep the concrete mixed evenly. [0003] In the process of concrete mixing, since there is inevitably a certain gap between the feed inlet and the mixing drum, for a concrete mixer truck full of materials, when driving on a bumpy road or uphill, the concrete mortar in the mixing drum, etc. It is easy to overflow from the gap, thereby spilling on the road surface, etc., causing pollution to the surrounding environment, and there is no better solution at present. Contents of the invention [0004] The present invent...
