Description

Technical Field

[0001] The invention relates to a vegetable harvesting machine, in particular to a pepper fruit removing device. Background Art

[0002] With the continuous expansion of the area and population that eat spicy food, the deep processing of peppers has developed rapidly. In recent years, the planting area and output have remained high. However, due to the large amount of manpower required in each link of pepper planting and harvesting, there are currently backward planting methods, high labor intensity, low harvesting efficiency, and problems such as de-cleaning rate, impurity rate, and skin damage, which cannot meet the requirements of commodity purchase. Now, in addition to large-scale growers using large-scale machinery for harvesting, a two-stage harvesting method is generally adopted, namely whole plant harvesting and seedling harvesting. Whole plant harvesting means that all pepper fruits are mature, the seeds are full, and the pepper seedlings are pulled up by the roots; seedling harvesting means harvesting with a sickle, drying, and then feeding the pepper fruit remover manually for de-peppering. Most pepper fruit removers use axial flow fruit removers, which have the following shortcomings: first, the pepper fruit removal travel is long, which cannot meet the requirements of the finished product, the fruit removal rate is low, the loss is large, and finally manual picking is still required; second, the machine is large in size and is not suitable for small-scale professional growers. Therefore, it is necessary to improve the product performance of pepper fruit removers and improve the mechanization of pepper harvesting. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a device for removing pepper fruits. In view of the problems of long drum threshing stroke, high breakage rate, high impurity rate and low threshing rate existing in the current pepper fruit threshing machines, the device adopts tangential feeding threshing and utilizes two combinations of spiked combs to remove the pepper fruits, thereby preventing the pepper fruits from being damaged and improving production efficiency.
