AI Technical Summary
The fixed tilting and unloading heights of existing corn harvesters limit the transport capacity of the receiving trucks, making it impossible to meet production demands.
A corn harvester grain bin structure with a two-stage lifting mechanism is designed. The grain bin body is lifted and tilted by sliding connection of fixed frame and floating frame, combined with first and second actuators, thereby increasing the unloading height.
It enables the efficient transport of more corn ears on complex terrain, thereby improving production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a corn harvester granary structure of secondary lifting type. BACKGROUND
[0002] The overturning height of the granary of the existing corn harvester is fixed, and the unloading height is also fixed, in this case, the height of the grain receiving vehicle of the harvester is limited to a fixed height, and since the height of the surrounding plate of the bin of the grain receiving vehicle is limited by the overturning height of the granary of the corn harvester, the amount of corn ears transported at a time is a fixed value, therefore, the existing grain receiving vehicle cannot meet the existing production demand due to the limitation of the height of the granary. SUMMARY
[0003] The utility model discloses a corn harvester granary structure of secondary lifting type.
[0004] A corn harvester granary structure of secondary lifting type, comprising a fixed frame, a floating frame, a granary box, a first actuating mechanism and a second actuating mechanism, the floating frame is slidably connected with the fixed frame, the rear end of the granary box is hingedly connected with the top end of the floating frame, the first actuating mechanism is used for driving the floating frame to lift relative to the fixed frame, and the second actuating mechanism is used for driving the granary box to overturn.
[0005] Further, the fixed frame comprises two oppositely arranged supports, the supports are provided with a first fixed leg and a second fixed leg, the upper end of the second fixed leg is fixedly connected to the first fixed leg through a connecting piece, a predetermined angle is arranged between the first fixed leg and the second fixed leg, and the two supports are connected through a plurality of connecting rods.
[0006] Further, the floating frame comprises a first floating leg and a second floating leg, the first floating leg and the second floating leg are connected through a connecting rod, the first floating leg is slidably arranged in the first fixed leg, and the second floating leg is slidably arranged in the second fixed leg.
[0007] Further, the first actuating mechanism comprises two first oil cylinders, the bottoms of the two first oil cylinders are respectively connected to the two first fixed legs, and the floating joints of the two first oil cylinders are respectively connected to the first floating leg and the second floating leg.
[0008] Further, the second actuating mechanism comprises two second oil cylinders, the bottoms of the two second oil cylinders are respectively connected to the first floating leg and the second floating leg, and the floating joints of the two second oil cylinders are respectively connected to the granary box.
[0009] Beneficial effects: compared with the prior art, the utility model discloses a grain depot support leg's telescopic structure promotes the unloading height of grain depot, and in the harvesting process, due to the promotion of the unloading height, the apron of the grain receiving vehicle can be higher, and more kinds of grain receiving vehicles can be adapted, and better efficiency is obtained on the complex ground such as ridge, so that more ear is transported single time, and production efficiency is improved.
