Description
Technical Field
The utility model belongs to the technical field of agricultural machinery, concretely relates to novel sunflower thresher.
Background
In recent years, agricultural production has been gradually mechanized, and in order to promote economic development and meet production requirements, economic crops are more and more emphasized, wherein the sunflower industry is rapidly developed, and the corresponding sunflower planting area is wider and wider. After the sunflower is harvested, the sunflower needs to be threshed firstly, and if the sunflower is just harvested and is not threshed in time, the sunflower disc will be rotted, so that great loss can be caused to farmers, but the sunflower threshing method has many problems. At present, in regions with relatively backward production in China, people continue to thresh sunflowers by using a traditional mode of striking with hands and a wooden stick, the speed is slow, the damage is more, the production efficiency is low, if the threshing is not timely, the threshing is easy to mildew and rot, more manpower needs to be invested, and particularly in northeast regions with high sunflower yield and wide-spread people, the economic benefit obtained by sunflower planters using traditional threshing methods is not optimistic. The sunflower threshing device used in relatively developed areas is complex in operation, expensive in price and huge in equipment, is well applied to large sunflower processing plants, and is not suitable for common planters.
