Description

Technical Field

[0001] The utility model belongs to the technical field of concrete manufacturing, and particularly relates to a feeding device for a concrete mixer. Background Art

[0002] By using a feeding device, raw materials (such as cement, gravel, sand, etc.) can be quickly and accurately transported to the interior of the mixer. At the same time, the feeding device can continuously provide raw materials to the mixer during the mixing process, thereby ensuring the continuity and stability of the mixing process and improving production efficiency. In the prior art, a motor, a cylinder and a material box are usually set, and the motor drives the cylinder to rotate so that the material box is lowered. The cylinder can be used to shovel the raw materials and then rotate to a suitable position for feeding. However, in this method, the discharge range of the material box cannot be adjusted. Therefore, when processing different batches or different types of raw materials, it may not be possible to adapt to the optimal feeding speed and amount, thereby affecting production efficiency.

[0003] For example, the utility model with announcement number CN217670232U discloses a feeding device for a concrete mixer. In the technical solution of this patent, a motor is arranged on the base, and the output end of the motor is connected to a cylinder. The bottom of the cylinder is hinged to the base, and the output end of the cylinder is bolted to a material box. The motor drives the cylinder to rotate, so that the material box is lowered. By utilizing the action of the cylinder, the material box can shovel and collect raw materials, and then rotate to a suitable position for feeding. However, this method cannot meet the demand of adjusting the discharge range of the material box according to the size of the feed port of the mixer. For different mixers, the size and shape of the feed port of the mixer are different. The fixed material box discharge port cannot more effectively receive and guide the material into the mixer, which may make it inconvenient to control the concrete placement position at the construction site, affecting the construction progress and efficiency. When processing different batches or different types of raw materials, it may not be able to adapt to the optimal feeding speed and amount, thereby affecting production efficiency.
