Abstract

At present, farmers in remote areas of China still rely on traditional methods to raise cattle and sheep, which results in low efficiency and high labor costs. Therefore, most ordinary farmers urgently need a miniature feed mixer to process crop by-products into feed that can be consumed by livestock. Although the micro mixer is small in size, due to the toughness and strength of the grass, it still has the same cutting force of the twisting arm and the kneading wire as the large feed mixer. Therefore, during the operation of the mixing operation, it will produce relatively large impact and vibration noise. In response to the above issues, this article uses the finite element method to model and analyze the vibration characteristics of the silo part of a small fully mixed feed mixer. It is found that the first two natural frequencies of the structure are exactly within its working frequency range, and resonance phenomena will inevitably occur. This will generate noise that causes harm to the human body and also damage the structure of the feed machine, affecting its normal operation and damaging working components, Reduce the service life of the feed mixer. So, based on its first six modal shapes, the structure was optimized and improved, and finally a structure was designed that can effectively avoid the working frequency of a small fully mixed feed mixer.
