Description

Technical Field

[0001] The present application relates to the technical field of concrete, and in particular to a mixing device. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering. When concrete is needed, a mixing device is usually required to mix concrete with water.

[0003] For example, a concrete

[0004] A soil mixing device, the utility model opens the barrel cover by pulling the handle, pours the concrete raw materials into the interior of the mixing barrel shell, at this time, the mixing motor is turned on, and the mixing gear starts to rotate under the rotation of the driving wheel. During the rotation, the mixing gear stirs the inner wall of the mixing barrel shell, and at the same time, the stirring plate on the inner wall of the mixing gear mixes the concrete in the barrel. The angle between the stirring plate and the mixing gear can make the concrete rotate with the mixing gear, and can effectively stir the concrete close to the inner wall of the mixing barrel shell to prevent uneven stirring from causing concrete solidification. After the mixing is completed, the entire device can be pushed by the cart handle according to the construction position of the workers, and it is convenient to move to the designated position for construction under the action of the universal ball wheel.

[0005] In the above patent, concrete can be stirred to prevent concrete lumps from adhering to the inner wall of the mixing barrel, but the device uses a discharge port to discharge the mixed concrete. The discharge port is arranged on the inner side of the mixing barrel. When discharging, it is easy for concrete to accumulate on the device and affect the use of the concrete. It is also easy for concrete to adhere to the inside of the discharge port, causing the discharge port to be blocked and affecting the use of the device. Utility Model Content
