Description

A Concrete Mixer Convenient for Feeding and Unloading

technical field

The utility model belongs to the technical field of mixers, in particular to a concrete mixer which is convenient for feeding and discharging materials.

Background technique

Concrete mixer is a machine used to mix cement, sand aggregate and water and mix it into concrete mixture. Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by mixing cement with cement as cementing material, sand and stone as aggregate, and water (may contain admixtures and admixtures) in a certain proportion, also known as ordinary concrete. Concrete is widely used in civil construction engineering. In construction engineering, concrete mixers are often used to mix concrete.

The invention with authorized publication number CN 106476141 A discloses a concrete mixer, which includes a mixing box, a feeding device and a water inlet device. The position of the water device is provided with a water inlet, and a stirrer is provided inside the stirring box. The stirrer includes a stirring shaft arranged in the center of the stirring box and a plurality of stirring blades of different lengths arranged on the stirring shaft. There is a drive, an isolation plate is set between the agitator and the drive, and a discharge port is set on the isolation plate. The lower part of the feeding device and the water inlet device are equipped with an electronic weighing device. The electronic weighing device is connected with the controller. There is a feeding pipe under the feeding device, and an electric control feeding valve is arranged on the feeding pipe. The water inlet valves are all connected with the controller. However, the technical solution of this patent has the following defects: when taking out the mixed concrete, due to the driver provided at the lower end of the mixer, the mixed concrete can only be extracted from the feeding device using a suction pump. This increases the difficulty of concrete unloading, which will increase the workload of the staff. At the same time, it will be difficult to take out the concrete at the bottom of the inner side of the mixing tank if it is taken out by a suction pump, resulting in retention and waste of resources.

Therefore, in order to facilitate the removal of the mixed concrete, reduce the labor intensity of the staff, reduce the retention of concrete at the bottom of the mixing tank, and make full use of resources, a concrete mixer that is convenient for feeding and unloading is urgently needed to solve the existing problems.
