Description

A mortar mixer

Technical field

The utility model relates to the technical field of mortar mixers, in particular to a mortar mixer.

Background technique

Mortar mixer is a machine that mixes cement, sand and gravel aggregates and water into a mortar mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. After mixing, it is usually necessary to tilt the bracket to export the internal mortar.

After searching, the existing Chinese patent with publication number CN215396049U discloses a vertical mortar mixer. By placing the barrel on the bracket, the mortar inside the bucket can be poured by rotating the bracket, and the limiting mechanism on the bracket is used. The barrel can be fixed to prevent the barrel from moving during blanking, resulting in deviation of the blanking position and waste of mortar. The limit rod limits the position of the barrel, making the barrel more stable when rotating, and the rotation is The ring is easily connected to the limit rod, so that the barrel will not slide when pouring mortar, and the use effect is better. The cylinder drives the rack to move, and the rack drives the gear on the bracket to rotate, which can drive the bracket to rotate, so that the material There is no need to use manpower to rotate the bracket when the barrel is unloaded, which saves more manpower.

The above-mentioned technical solution has the following disadvantages. Although such a mortar mixer structure can drive the barrel to dump by rotating the bracket to discharge the internal mortar during use, in actual use, the mortar has high adhesion and needs to be dumped at a larger angle. Only then can the mortar in the barrel be completely poured out, which makes the overall center of gravity of the mixer advance, resulting in poor overall stability, and the top mixing mechanism rotates and opens to separate from the barrel. Such a structure has a limited range of movement during use, and the mixing The leaves are prone to damage due to collision with the barrel.

In view of this, this creation improves and solves the above problems, and after painstaking research and application of academic theory, a technical solution that is reasonably designed and can effectively improve the above defects is proposed.

The information disclosed in this Background section is merely intended to enhance understanding of the general background of the present invention and should not be construed as an admission or in any way implied that the information constitutes prior art that is already known to those skilled in the art.
