A green walnut peeling machine

Abstract

The invention discloses a green walnut peeling machine, which belongs to the technical field of agricultural machinery. It includes a frame, a transmission device and a peeling device. The peeling device includes an inner knife cylinder (1), an inner blade (2), an outer knife holder (4) and an outer blade (5). The inner knife cylinder (1) is provided with a Rotating shaft (7), multiple inner blades (2) parallel to each other are uniformly welded on the outer circumference of the inner knife cylinder (1), and multiple outer blades (5) are welded inside the outer knife holder (4), which is characterized in that: The outer knife rest (4) is arranged on the inner knife cylinder (1) by two groups in a spiral shape, and the upper part of the outer knife rest (4) is provided with a walnut conveying track (6), and the outer knife rest (4) The lower part is provided with a walnut conveying lower track (3), and the section of the walnut conveying upper track (6) and the walnut conveying lower track (3) is trumpet-shaped. The invention can prolong the walnut conveying and cutting action time in the machine, so that the damage rate of the green walnut is low and the cleaning rate is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a green walnut peeling machine. Background technique [0002] The maturity time of walnuts is relatively concentrated. During the walnut harvest period, a large number of mature green walnuts will urgently need to be peeled. If the walnut green skins are not removed in time, the quality of walnut kernels will be affected. The prior art discloses several mechanical walnut peeling machines, such as a green walnut peeling machine (patent number CN204070440 U), which includes a frame, a barrel, and a transmission mechanism. The barrel is provided with a rotating shaft, and its characteristic In that: the material cylinder is composed of an upper cylinder and a lower cylinder, the lower cylinder is fixed on the upper cylinder by adjusting bolts, the upper part of the lower cylinder is provided with a feeding hopper, and the rotating shaft is fixed by a beari...

AI Technical Summary

Problems solved by technology

Although this patent has beneficial effects such as compact structure, small floor space, light weight, and being able to adapt to walnut varieties with different transverse diameters, due to the rotor blades provided on the conical rotor and the cylinder blades provided on the inner wall of the lower cylinder The strips and walnuts are hard extruded, and the inner wall of the cylinder is made of stainless rigid material, so it is easy to damage the walnut green skin during extrusion and peeling, resulting in a high breakage rate, and because the cylinder blade is vertical shape, and the rotor blade on the conical rotor is obliquely straight, so when the green-skinned walnut enters the cylinder, the peeling time between the green-skinned walnut, the rotor blade and the cylinder blade is very short. If the walnut greenskin is thick If it is not, the green skin cannot be removed in a short time, resulting in a low removal rate, and because of the small space between the cylinder blade and the rotor blade, during the green skin cutting process, the peeled walnuts will also have patina phenomenon, which will cause Make the walnut skin black in a short time, which seriously affects the appearance quality of the walnut

[0003] In short, there are many kinds of walnuts in my country, with large size differences and irregular shapes. The thickness and strength of walnut shells also vary greatly. The effect of the existing green walnut peeling machines is not very satisfactory. Partial cutting of green walnuts cannot fully and effectively cut the green skin on the entire outer circumference of the walnut, and the problem of patina during walnut peeling is a problem that cannot be solved by existing walnut peeling machines.
