The second drive shaft 203 is opposite to the first drive shaft 202 in position, and is respectively located on the left side and the right side of the grain bin. The first drive shaft 202 is arranged at the right end of the grain bin, and the second drive shaft 203 is arranged at the left end of the grain bin. The second drive shaft 203 is connected to the first drive shaft 202 through the third drive shaft 204 to realize transmission.

The second connecting shaft 3012 is arranged perpendicular to the direction of the first connecting shaft 3011. The second connecting shaft 3012 is connected to the transmission part of the harvester. One end of the second connecting shaft 3012 is sleeved with a second gear 3012a. The second gear 3012a meshes with the first gear 3011a. The other end of the second connecting shaft 3012 is sleeved with a second bearing 3012b and a third end cover 3012c. The fixed shaft assembly 301 is further provided with a third gear 3013 connected to the grain elevator. The third gear 3013 meshes with the first gear 3011a, and the first gear 3011a is connected to the auger 102 in the grain elevator 1 to drive the auger 102 in the grain elevator to rotate.

The driving power of the harvester is transmitted from the second gear 3012a to the first gear 3011a, and then the first gear 3011a rotates to drive the third gear 3013 to rotate, and the auger 102 in the grain elevator 1 rotates following the third gear 3013.

[0038] In this embodiment, support seats 206 are further respectively provided on the first drive shaft 202 and the second drive shaft 203.

[0039] The embodiment also provides a harvester, which includes the above-mentioned grain bin. By adopting such a grain bin, the harvester can avoid being overweight during operation, thereby affecting the performance and service life of the harvester.

[0040] In summary, a grain bin and a harvester are provided. By setting the drive oil cylinder 201, the display boards on the four sides of the top of the grain bin are driven to open to form a secondary grain bin, so as to increase the storage capacity of the grain during the operation of the harvester. The grain lifting cylinder 1 is lifted as the display board opens and closes, and the position of the grain outlet 103 of the grain lifting cylinder is adjusted, so that the falling point of the harvested grain changes, making the grain evenly distributed in the grain bin, and avoiding the situation that the grain bin is overweight, which affects the harvesting safety, the service performance of the harvester and reduces the service life. At the same time, the increase in the storage capacity of the grain bin also reduces the time for parking and unloading the grain, further improving the harvesting efficiency of the harvester.
