A turnover mechanism for a harvester bin

By designing a tilting mechanism, the grain bin is made synchronously linearly moved and tilted by the cooperation of a threaded rod and a fixed plate. This solves the problem of the harvester tilting due to its increased center of gravity, and ensures the safety and accuracy of the unloading process.

AI Technical Summary

Technical Problem

The existing combine harvester grain bin tipping device lifts the grain inside the bin to a high place and flips it over during unloading, causing the combine harvester's center of gravity to rise suddenly, increasing the risk of tipping over, especially when used on uneven ground.

Method used

A flipping mechanism was designed, in which a drive component drives a threaded rod to rotate, a sliding block slides along the threaded rod, and a fixed plate cooperates with the rotating rod to achieve synchronous linear motion and flipping of the grain bin, maintaining a stable center of gravity; at the same time, springs and counterweights are used to control the opening and closing of the sealing cover to ensure accurate grain leakage.

Benefits of technology

This effectively prevents the harvester from shifting its center of gravity during grain unloading, reduces the risk of tipping over, ensures accurate grain discharge, reduces waste, and improves the safety and practicality of the device.

Abstract

The utility model discloses a kind of overturning mechanisms for harvester granary, its technical key points include harvester body, granary body and overturning device, one side of overturning device is fixedly connected with one side of harvester body, one side of granary body is fixedly connected with the side of overturning device away from harvester body, overturning device is set, driving assembly drives two threaded rods to rotate, since fixed plate is rotatably connected with two sliding blocks, and two rotating rods are rotatably connected on fixed plate, during the process that fixed plate slides towards driving assembly along with two sliding blocks, fixed plate will rotate around two sliding blocks, although granary body and grain inside granary body will rotate, but granary body and grain inside will simultaneously linear motion towards driving assembly at this time, at this time, granary body is still on harvester body, at this time, it can avoid overall device gravity center deviation, reduce the risk of harvester body rollover.
