Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery field especially relates to a peanut sheller. BACKGROUND

[0002] Peanut is important oil crop and economic crop. In the processing of peanut, shelling is a key link. The traditional peanut shelling mainly relies on manual operation, and the efficiency is low and the labor intensity is big. With the development of agricultural mechanization, peanut sheller emerges as the times require.

[0003] The two fans on the existing peanut sheller are usually driven by two driving mechanisms respectively, or two shafts are used to drive the two fans respectively. These two designs greatly increase the manufacturing and installation cost of the equipment, and during work, the shelling and blowing of peanuts are affected due to the inconsistent start of the two fans, thereby reducing the shelling efficiency of peanuts. The existing peanut sheller usually adopts a simple mechanical structure to perform shelling through extrusion, friction and other methods. Due to the similarity of size, shape and weight between peanut shell and peanut kernel, after the shelling step of peanut is completed, when the fan blows the peanut shell outward, the peanut kernel and the peanut shell fall down at the same time, and part of the peanut kernel will block the peanut shell, so that the wind blown by the fan to the peanut shell is blocked by the peanut kernel, thereby part of the peanut shell cannot be blown to the outside by the fan. These peanut shells will fall down with the peanut kernels, thereby reducing the shelling rate of peanuts. This situation not only affects the quality of peanut products, but also increases the cost and workload of subsequent manual sorting. Therefore, how to develop a new type of peanut sheller has become a problem to be solved by technical personnel in the field. SUMMARY
