AI Technical Summary

Technical Problem

Traditional swing-type grain silos have low unloading efficiency, are complex and difficult to operate, have a small range of movement, and require precise alignment with the unloading position.

Method used

The four-bar linkage consisting of the frame, first link, and second link, combined with the drive component and locking assembly, enables the smooth swinging and horizontal displacement of the bin, optimizes the unloading angle, and simplifies operation through the automatic opening of the bin door.

Benefits of technology

It improves unloading efficiency, reduces operational difficulty, increases the movement range of the hopper, enables materials to be accurately unloaded to the preset position, simplifies the unloading process, and improves the operating efficiency of the combine harvester.

Abstract

Embodiments of the present disclosure relate to the technical field of harvesting machines, and one embodiment of the present disclosure provides a swing type grain bin for a combine harvester, which comprises a frame body, a bin body, the first side of the bin body being provided with a discharge port, a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod connecting the frame body and the bin body to form a four-bar linkage, the four-bar linkage being capable of swinging to move the bin body between a discharge position and an initial position, when in the discharge position, the height of the first side of the bin body is lower than the height of the second side of the bin body, so as to unload materials to a preset receiving position, when in the initial position, the height of the first side of the bin body is equal to or higher than the height of the second side of the bin body, the second side being opposite to the first side, the first side being closer to the preset receiving position than the second side, and the discharge position being closer to the preset receiving position than the initial position, and a driving member, the driving member driving the four-bar linkage to swing. Through the above technical solution, the technical problem of low unloading efficiency of the swing type grain bin in the related art is solved.
