AI Technical Summary

Technical Problem

When using existing concrete mix proportioning devices, materials tend to fall out of the gaps in the mechanical structure, resulting in poor proportioning. Furthermore, when the device is not in use, the materials tend to stick and accumulate, making it impossible to automatically discharge them.

Method used

The design of the arc-shaped storage tank and rubber deformation block ensures that the material is received when it rotates to the top and detached from the contact area when it rotates to the bottom. Combined with the use of an air pump and an electromagnet, it achieves accurate metering and automatic material feeding.

Benefits of technology

It achieves precise quantitative measurement and automatic feeding of materials, avoids material leakage and clumping, and improves the accuracy and efficiency of feeding.

Abstract

This application discloses a concrete mix proportioning device, relating to the field of concrete mixing technology, including a mixing component, which comprises a mixing element, a storage element, and a metering element. The mixing element includes a mixing tank, the storage element includes a storage cylinder, and the metering element includes a rotating drum, a storage trough, a deformable block, and a motor. The storage cylinder is fixed to one side of the mixing tank, and a rectangular storage trough is formed through the top and bottom of the storage cylinder. The rotating drum is rotatably disposed inside the storage cylinder and has a storage trough with an arc-shaped cross-section. The storage trough is used to store a fixed quantity of material. Deformable blocks are fixed on both sides of the storage trough and are fixed to the rotating drum. The deformable blocks are made of rubber. This device enables precise metering. When the storage trough rotates to the top, it receives the material, and when it rotates to the bottom, it disengages from the material contact area, ensuring that only a fixed quantity of material is taken out each time. The rubber deformable block undergoes elastic deformation when the material protrudes from the storage trough, such as when the material collides with a guide plate, to prevent the rotating drum from jamming or being damaged.
