Full-automatic mechanical grain unloading device of reaping machine

Abstract

The invention discloses a full-automatic mechanical grain unloading device of a reaping machine. The full-automatic mechanical grain unloading device comprises a grain unloading hopper; a hinge shaft is fixed on the grain unloading hopper; the grain unloading hopper is rotationally mounted at a grain discharge opening through the hinge shaft; a grain discharge hopper control mechanism comprises a grain discharge hopper control rotating arm, a grain discharge hopper driving rotating arm and a pull rod component connected between the grain discharge hopper control rotating arm and the grain discharge hopper driving rotating arm; a support shaft is nested on the grain discharge hopper control rotating arm; the support shaft is mounted on a support seat; a grain unloading hopper control rod is fixed on the grain discharge hopper control rotating arm; a grain unloading clutch control mechanism comprises a grain unloading clutch control rotating arm which is nested on the support shaft; a grain unloading clutch control rod is fixed on the grain unloading clutch control rotating arm; and interlocking plates are arranged on the grain unloading hopper control rotating arm and the grain unloading clutch control rotating arm respectively. The grain unloading device provided by the utility model has high degree of automation, and can open and close the grain unloading hopper without the assistance of human, thereby preventing damage of components caused by misoperation.

Description

technical field [0001] The invention relates to a grain unloading device for a harvester, in particular to a fully automatic mechanical grain unloading device for a harvester. Background technique [0002] Domestic combine harvesters equipped with unloading hoppers, first, need to manually open the unloading hopper to unload the grain when unloading the grain, and then manually close the unloading hopper after the unloading is completed, the operation is laborious and laborious, and the working efficiency of the harvester is low. The unloading operation takes a long time. The second, when controlling the grain unloading hopper and the grain auger, the actions are uncoordinated, causing damage to parts such as the grain auger and the grain unloading hopper. Furthermore, if the grain outlet is not closed tightly, the grains will usually overflow, resulting in waste. In addition, many of the current grain unloading devices are operated by the joystick rotating up and down lef...
