Description

Grain unloading device for a foldable corn ear box

technical field

The utility model relates to an agricultural machinery accessory, in particular to a grain unloading device for a foldable corn ear box.

Background technique

Today's corn harvester technology has been widely recognized, but due to the needs of users and the limitation of supporting power, the degree of mechanization of ear unloading has been reduced, workers have many work links, and the labor intensity is high, which increases additional labor and reduces work. efficiency.

Contents of the invention

The technical task of the utility model is to provide a grain unloading device for a foldable corn ear box with high working efficiency and low labor intensity for the above deficiencies.

The technical scheme adopted by the utility model to solve its technical problems is: the device comprises an ear box suspension frame, an ear box support, a grain unloading door panel and a grain unloading oil tank, the ear box support is fixedly installed on the ear box suspension frame, and the ear box support is a The top of the side is connected to the top of the side folding plate through hinge three; the bottom of the side folding plate is connected to one end of the bottom folding plate through hinge one; the top of the other side of the ear box support is connected to the top of the grain unloading door plate through hinge two Connection; a support rod is arranged between the lower part of the side folding plate and the middle part of the grain unloading door plate, and the lower part of the side folding plate is hinged to the grain unloading oil cylinder relative to the other side of the connecting support rod.

The two ends of the support rod are respectively hinged with the side folding plate and the grain unloading door plate.

The side folding plate is inclined at an angle of 10°-20° relative to the ear box support in the vertical direction.

The side folding board, the bottom folding board and the grain unloading door board are of a single board structure or a parallel double board structure connected by connectors.

When unloading grain, with the help of the force of the unloading oil cylinder, the angle of the side folding plate continues to increase, and due to the action of the hinge and the support rod between the side folding plate and the bottom folding plate, the inclination angle of the two increases. At the same time, the grain unloading door panel is opened.

Compared with the prior art, the grain unloading device of a foldable corn ear box of the utility model has the characteristics of reasonable design, compact structure, easy processing, convenient use, high working efficiency, and reduced labor intensity of workers.
