Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a harvester top cover assembly. Background Art

[0002] Harvester is an integrated machine for harvesting crops. It completes harvesting and threshing at one time, and collects the grains into the storage bin, and then transports the grains to the transport vehicle through the conveyor belt. It can also be harvested manually, by laying the straw of crops such as rice and wheat in the field, and then picking up and threshing them with grain harvesting machinery. The top of the harvester's grain bin will be equipped with a top cover, and there will be a transparent plate on the top cover for the driver to observe the situation inside the cabin.

[0003] However, the existing transparent plates are riveted to the top cover by rivets. After long-term use, when the transparent plate becomes blurred and needs to be replaced, it is necessary to use a drill to pierce the rivets and remove them, and then re-drill and rivet them. The replacement efficiency is low and the difficulty is great. Therefore, a harvester top cover assembly is proposed. Utility Model Content
