Peanut huller

Abstract

The invention relates to a peanut huller which is characterized by comprising a feeding hopper, a rotary drum, a rotary drum shaft, a notch board sieve, a material collecting drum, a material receiving board, a motor and a rack; the exterior of the rotary drum is fixed with an inverted cone-shaped vertical type hollow drum with spiral bulged ribs; the notch board sieve is also in an inverted cone shape; the annular hulling region between the rotary drum and the notch board sieve is gradually contracted from top to bottom; and the upper end of the rotary drum is provided with a cone-shaped uniform distributor with a spiral rib board. The peanut huller has the advantages that a vertical type hulling mode is adopted; the large area of the notch board sieve is effectively utilized and the hulling speed is enhanced so as to enhance the hulling efficiency; the rapid separation of peanuts from the hulling region is realized so as to avoid the peanuts from remaining in the hulling gap; the damage is decreased so as to reduce the damage rate of the peanuts; thus, the peanut huller can automatically adapt to the actual condition of different shape sizes of the peanuts; the hulling damage is lightened, and the completely hulling rate and the hulling efficiency are enhanced; and the hulling gap can be adjustable to adapt to the hulling of the peanuts with different varieties and shape sizes.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a peanut sheller for shelling peanuts. Background technique [0002] At present, people use a horizontal peanut shelling machine to shell peanut pods. The main components of the shelling machine are an open shelling cage (shelling drum) and a grid concave screen. The principle of shelling is to rely on high-speed The horizontally rotating shelling and breaking cages hit, squeeze and knead the peanut pods, causing the peanut pods to break and break, and the broken peanuts and peanut shells are separated from the grid concave screen, and then the peanut shells are blown by the fan. The air flow is blown out from the miscellaneous outlet, and the peanuts flow to the inclined vibrating screen and then flow out after being screened. [0003] This horizontal peanut shelling machine still has some disadvantages: the grid concave plate sieve is semi-cylindrical, the effective working area is s...

AI Technical Summary

Problems solved by technology

[0003] This horizontal peanut shelling machine still has certain disadvantages: the grid concave screen is semi-cylindrical, the effective working area is small, and the screening efficiency is low, resulting in The shelling efficiency of the whole machine is low; the fed peanuts and shelled peanuts and peanut shells are mainly concentrated at the bottom of the concave plate sieve with a limited area under the action of gravity, forming a thick material layer. The effective area of ​​the concave plate sieve is small, and the peanuts after shelling cannot be separated quickly, so the peanuts, peanut shells and peanut pods are mixed together in the shelling area, which increases the residence time in the shelling gap and is The number of times of agitation increases the probability of damage, and the damage rate of peanuts after shelling is high; the traditional horizontal peanut shelling machine is difficult to adjust the shelling gap, so the applicability to shelling of different varieties of peanuts is poor
