Peanut sheller

Abstract

The invention belongs to the field of agricultural mechanical equipment and particularly provides a peanut sheller. The peanut sheller comprises a rack, a feeding hopper, a shelling mechanism and a driving mechanism, wherein the shelling mechanism comprises an upper jaw plate fixedly installed on the rack and a lower jaw plate with two ends hinged to the lower portion of the upper jaw plate respectively through a long hinge rod and a short hinge rod, an included angle formed by the upper jaw plate and a horizontal line is 6-10 degrees, an included angle formed by the lower jaw plate and a horizontal line is 2-4 degrees, and multiple protruding shelling units are evenly arranged on the lower surface of the lower jaw plate and the upper surface of the lower jaw plate at intervals. The driving mechanism drives the lower jaw plate to perform back and forth swing around the upper jaw plate with the long hinge rod and the short hinge rod as swing arms. The peanut sheller is novel in concept and simple in structure, the upper jaw plate and the lower jaw plate are adopted to form a wedge-shaped dynamic shelling space, the protruding shelling units can inwards extrude, drag and crush peanuts from an inlet of the wedge-shaped space stage by stage, and the peanut threshing rate is greatly improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and specifically provides a peanut sheller. Background technique [0002] At present, in terms of agricultural production, most of the shelling of peanuts has been carried out by mechanical equipment. The structure of the existing peanut shelling machines is roughly similar, and its main components are the open shelling and beating cage (shelling drum) and the grid concave screen. , Squeeze and knead the peanut pods to break and break the peanut pods. The broken peanut kernels and broken peanut shells are separated from the grid concave screen, and then the peanut shells are blown out from the miscellaneous discharge port by the airflow of the fan, and the peanut kernels The flow is screened on an inclined vibrating screen and then discharged. The breakage rate of peanut kernels after shelling by the peanut sheller using this principle exceeds 7%~8%, and even reaches 10% in...

AI Technical Summary

Problems solved by technology

[0003] The Chinese invention whose authorized notification number is CN102551177B: a peanut peeling machine discloses a shelling mechanism, which includes a guide rail arranged horizontally on the frame, a fixing plate and a The movable sieve plate and the fixed plate are fixed on the frame, and are arranged obliquely above the movable sieve plate. The movable sieve plate is driven by the power mechanism to move back and forth on the horizontal guide rail repeatedly to shell the peanuts. Although the shelling mechanism operates at a certain To a certain extent, the shelling of peanuts is realized, but since the movable sieve plate has been moving in the horizontal direction, the wedge-shaped space formed between it and the fixed plate is actually fixed, which is not conducive to the sliding and rolling of peanuts in the wedge-shaped space when the movable sieve plate moves , affecting the breaking efficiency of peanuts
