AI Technical Summary

Technical Problem

Existing feeding devices have complex structures. If materials are fed directly into the feeding cylinder without processing, it can easily lead to blockage, jamming and damage of the spiral blades, and the lifespan will be shortened after long-term use.

Method used

A crushing motor and a buffer platform are installed on the hopper of the feeding device. Multiple sets of vertical blades are used to initially crush and disperse the material, reduce the material mass and disperse its position in the feeding cylinder, and reduce the pressure on the feeding cylinder, conveying shaft and spiral blades.

Benefits of technology

It effectively avoids deformation and damage to the spiral blades, extends the service life of the device, and reduces jamming by dispersing materials, thereby improving the reliability and durability of the device.

Abstract

This utility model relates to a feeding device, specifically a feeding device with a protective structure. The feeding device includes a feeding structure and a hopper fixed to the feeding structure. A protective structure is provided on the hopper. The hopper is a hollow cavity structure with openings at both ends. The protective structure includes a crushing motor and a buffer platform located on one side of the crushing motor. The crushing motor is fixed to the outside of the hopper, and a support shaft is fixed to the output end of the crushing motor. Multiple sets of vertically arranged blades are fixed on the support shaft. The buffer platform is fixed inside the cavity of the hopper, and a conveying trough is provided through the buffer platform. The support shaft is located inside the conveying trough. This feeding device with a protective structure can significantly reduce the mass of the material before it falls into the feeding cylinder cavity, reducing the direct pressure on the feeding cylinder and spiral blades, preventing deformation and damage to the spiral blades, and preventing jamming, thus ensuring its long-term operation without damage.
