Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural machinery, and particularly relates to a grain bin of a harvester capable of automatically unloading grain by turning over a cover and the harvester. BACKGROUND

[0002] A grain bin unloading device of a corn harvester is disclosed in patent CN213073626U, which comprises a mounting frame, a support assembly is arranged on the mounting frame, the support assembly comprises a mounting rod, an extension rod and a support rod, the mounting rod is fixed on the mounting frame, the extension rod and the support rod are both arranged obliquely on the mounting rod, the extension rod is close to one end of the mounting rod, the support rod is arranged on one side of the extension rod, the end of the support rod away from the mounting rod abuts against the side of the extension rod close to the support rod, a grain bin is arranged between the extension rod and the support rod through a lifting and overturning mechanism, and the bottom surface of the grain bin abuts against the top surface of the mounting frame; when unloading grain, the position of the grain bin of the unloading device is lifted and then overturned, so that the corn in the grain bin can be completely poured out of the grain bin; however, when the harvester unloads grain, the following problems exist: since there is a certain distance between the transport vehicle and the grain bin of the harvester, when the harvester overturns to unload grain, the grain and fruits are spilled outside the transport vehicle, causing certain waste.

[0003] A grain bin of a corn harvester is disclosed in patent CN102884914B, which comprises a bin body, a guide bin plate of the bin body is provided with a guide groove for extending the unloading guide surface at the bin opening end, the guide groove is hinged on the bin body, the guide groove can be reciprocally overturned inwards and outwards of the bin, a turnover limiting mechanism for limiting the turnover angle of the guide groove and an elastic member for making the guide groove turn over and reset are arranged between the bin body and the guide groove; the turnover limiting mechanism has an unloading position and a walking position, at the unloading position, the guide groove is outwardly turned over to the groove bottom parallel to or coplanar with the guide bin plate or the groove bottom exceeds the extension line of the guide bin plate; at the walking position, the guide groove is inwardly turned over to the groove bottom in a vertical position under the action of the elastic member, however, the opening of the guide groove needs to rely on the gravity of the guide groove and the gravity of the corn in the bin to realize the opening when overcoming the elastic force of the tension spring, when the corn in the bin is too little or the broken cob is blocked between the guide groove vertical plate and the bin body plate, the opening of the guide groove is difficult to be realized completely relying on the gravity without the aid of other external force. Moreover, the vertical rising (closing) of the guide groove needs the tension spring to overcome the gravity of the guide groove to pull the guide groove back, therefore, the turnover opening and vertical rising of the guide groove are realized completely relying on the balance of the tension force of the tension spring and the gravity, which has relatively high requirements for conditions and insufficient working stability.
