Description

Technical Field

[0001] The utility model relates to the field of harvesters, in particular to a self-unloading granary for a small-sized harvester. Background Art

[0002] During the harvesting process, existing small harvesters currently use hanging grain bags to load grain. Grain bags can only hold 40 kg of grain. After a bag of grain is full, it is necessary to take the bag down, bundle it, and then place it on the pedal of the harvester. The main defects of this method are as follows: first, the grain bags filled with grain are stacked on the pedal of the harvester. Since the grain bags are not fixed, there is a risk of the grain bags falling during the operation, which is dangerous. At the same time, when the grain bags are replaced after they are full, the harvester needs to stop working for manual replacement, resulting in low efficiency. Utility Model Content
