Corn harvester and grain bin of corn harvester

Abstract

The invention discloses a corn harvester and a grain bin of a corn harvester. The corn harvester comprises a grain bin which comprises a bin body, a guide groove used for prolonging an unloading and guiding surface is arranged at a bin opening end of a guide bin plate of the bin body and is hinged on the bin body, the guide groove can overturn towards the inside and the outside of the bin in a reciprocating manner, an overturning limiting mechanism for limiting the overturning angle of the guide groove, and an elastic piece for overturning and resetting the guide groove are arranged between the bin body and the guide groove; the overturning limiting mechanism is provided with an unloading position and a walking position, when the overturning limiting mechanism is in the unloading position, the guide groove turns outwards until the bottom of the groove is turned outwards completely to be parallel to the guide bin plate or share one plane with the guide bin plate, or the bottom of the groove exceeds an extension line of the guide bin plate; and when the overturning limiting mechanism is in the walking position, the guide groove turns inwards until the bottom of the groove is in the vertical position due to the action an elastic piece. When the corn harvester walks or harvests, the guide groove erects due to the elastic action of the elastic piece, the whole width of the corn harvester is reduced, and the overturning limiting mechanism limits the rotation angle of the guide groove.

Description

technical field [0001] The invention relates to a corn harvester and a corn harvester granary, belonging to the technical field of agricultural machinery. Background technique [0002] At present, the corn harvester generally adopts a hydraulic side-turning granary. When unloading grain, the hydraulic transmission mechanism is controlled to push the granary to roll over to the corn transport vehicle located on one side of the granary. This kind of granary has the characteristics of fast unloading speed. The structure of the granary is as follows figure 1 As shown, the granary includes a silo body, and the silo body is surrounded by front and rear silo plates, a deflector plate 1 on one side of the granary rollover, and a side silo plate on the other side, wherein the deflector plate 1. It is an oblique warehouse plate that is inclined outward from the bottom of the warehouse to the mouth of the warehouse. This ensures that the grain in the warehouse can be poured out quickl...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of poor passing performance of corn harvesters in the prior art, the purpose of the present invention is to provide a corn harvester granary that can not only unload grain smoothly, but also make the corn harvester have good passability.
