Description

Technical Field

[0002] Peanut, also known as "long fruit", is a kind of nut with abundant production and wide consumption in my country. It belongs to the order Rosales and the family Leguminosae. It is an annual herb with an erect or creeping stem, 30-80 cm long, with separate wing and keel petals. The pod is 2-5 cm long and 1-1.3 cm wide, swollen, thick, and flowering and fruiting period is June to August. It is mainly distributed in Brazil, China, Egypt and other places.

[0003] After the raw peanuts are picked, the peanuts need to be de-tailed in batches. In the prior art, a peanut de-tailing machine is usually used to remove the peanut tails. However, most of the existing peanut de-tailing machines use de-tailing tooth knives to cut the peanut tails. During the cutting process, the broken peanut tails are easily stuck inside the tooth blades, which in turn affects the effect of subsequent peanut de-tailing. In addition, manual screening is still required after de-tailing to screen out the results that meet the requirements, which is quite time-consuming. Summary of the invention
