Description

Seed grain recovery unit Technical Field The invention relates to the technical field of kernel recovery of corn harvesters, in particular to a kernel recovery device. Background In the three large grain crops in China at present, the mechanized harvesting rate of wheat is over 90 percent, the mechanized harvesting rate of rice is about 70-80 percent, the mechanized harvesting rate of corn is not 70 percent, the gap is large, and the dominant mode of the mechanized harvesting of corn in China is the cluster harvesting mode. Because of the large difference of the corn agronomy and the physical characteristics of crops in different areas, the corn mechanical harvesting can not be realized by using a harvester structure like wheat and rice, and the domestic cross-region harvesting can be realized just because the cross-region operation brings good harvesting benefit to harvester owners, the great promotion of sales of the wheat-rice harvester is promoted, and the quick promotion of the mechanized harvesting rate is naturally driven. The corn agronomic problem is mainly characterized in that the corn harvesting states in different areas are greatly different, and the water content difference is greatly different when different corn varieties in different areas are harvested. The outstanding problem is that the corn harvesting in Huang-Huai-Hai region needs to take account of wheat and corn rotation, the season needs to be robbed, and the corn harvesting period is generally advanced, so that the time is favorably strived for the wheat rotation rushed planting. Therefore, crops are generally green when Huang-Huai-Hai corn is harvested in a wax ripening period, the corn has higher moisture content, the seeds falling in the process of peeling ears have high impurity humidity, the seeds cannot be directly returned to a granary, the seeds need to be stored in a seed recovery box, but the corn seeds are difficult to discharge from the seed recovery box due to high humidity, and the operation efficiency is affected. However, in northern single-season corn planting areas such as northwest, northeast and the like, corn is basically ripe at the time of harvest in a full-ripe period, the moisture content of the corn is low, and seeds falling in the process of peeling ears can be directly returned to the ear box, so that secondary seed unloading can be avoided. According to different corn planting technologies in each area, the grain recovery device configured by the corn harvester has various forms, namely a drawer type, a mechanical grain unloading type and a grain lifting recovery box. The requirements of users in different areas cannot be met, the cross-region operation cannot be realized, and the user income is low. Although there is also a dual-purpose seed recovery device for discharging the seed and returning the ear box, when the water content of the seed is high, the seed is easy to solidify in the recovery box, so that the seed is difficult to discharge, and the requirements of users in different areas still cannot be met. Disclosure of Invention The invention aims to provide the grain recovery device which can realize the direct return of grains to the ear box and can also be rapidly discharged from the grain recovery box and can meet different requirements of different areas on grain treatment modes. The invention discloses a grain recycling device for achieving the purpose, which comprises a grain recycling box and a grain elevator positioned at the outer side of the grain recycling box, wherein a grain conveying device is arranged in the grain recycling box, the lower end of the grain elevator is communicated with one end of the grain conveying device for outputting grains, the grain conveying device comprises a grain conveying opening and closing door positioned at the upper part of the grain conveying opening and closing door, when the grain conveying opening and closing door is completely opened, grains completely enter the grain conveying device through the upper part of the grain recycling box, and when the grain conveying opening and closing door is closed, a grain recycling gap is reserved between the grain conveying device and the side wall of the grain recycling box, and the grain conveying device is in a closed shape in the grain recycling box. When the seeds are required to be returned to the ear box, the seed conveying opening and closing door is opened, the seeds enter the seed conveying device and are conveyed to the seed elevator by the seed conveying device, then enter the ear box through the seed elevator, and when the seeds are required to be stored in the seed recovery box, the seed conveying opening and closing door is closed, and the seeds enter the seed recovery box through the seed recovery gap. The requirements on different treatment modes of the seeds can be easily met. Preferably, the grain conveying device is arranged in the grain recovery box in the front-back direction, the grain
