Pneumatic walnut hull breaking machine

Abstract

The invention provides a pneumatic walnut hull breaking machine and belongs to the field of forest fruits. The pneumatic walnut hull breaking machine consists of a machine frame, a transmission control device, a feeding mechanism and a hull breaking device. The hull breaking device is installed on the machine frame and consists of impact cylinders and holding cylinders which are installed among partition plates of a working rack in a connecting mode. The transmission control device is installed under the front portion of the machine frame and consists of an electric motor, a poking wheel, a control cam, a driving chain wheel, a grooved wheel, side-by-side front end chain wheels, a driven chain wheel, side-by-side back end chain wheels, a clamping switch, a holding switch and a strike switch, wherein the poking wheel, the control cam and the electric motor are sleeved coaxially, the driving chain wheel and the grooved wheel are sleeved on a lower shaft, the side-by-side front end chain wheels and the driven chain wheel are sleeved on an upper shaft, the side-by-side back end chain wheels are installed at the back portion of the machine frame, and the clamping switch, the holding switch and the strike switch are installed at the lower portion of the machine frame at intervals. The driving wheel, the driven wheel, the front end chain wheels and the back end chain wheels are respectively linked through chains, a material box is installed at the back portion of the working rack, a slot is arranged on one wall of the box, and the feeding mechanism is arranged under the position tightly close to the slot and consists of the side-by-side chains, rotary rollers installed on the chains at intervals in a connecting mode, rolling plate supporting the rotary rollers and tensioning chain wheels. The pneumatic walnut hull breaking machine is strong in adaptability on walnut types, complete in walnut hull separation, few in broken walnut nuts and high in hull breaking efficiency.

Description

Technical field [0001] The pneumatic walnut shell breaking machine of the present invention belongs to the field of forest and fruit machinery, and particularly relates to a walnut shell breaking device. Background technique [0002] At present, the walnut shell breaking method is mainly adopted at home and abroad by the fixed gap extrusion method. The main problems are: [0003] ① Poor adaptability to walnut varieties. Due to the irregular shape of walnuts, there are large differences in the dimensions, shell and kernel gap, shell thickness and hardness. The shell breaking machinery, equipment and devices manufactured according to this idea are only suitable for walnuts of the same variety and the same size. When the gap is larger than the size of the walnut, part of the walnut is not broken or only partially broken, and the one-time broken shell rate is low; [0004] ②The separation of shell and kernel is difficult. The shape of Chinese walnut varieties is mostly non-spherical....

AI Technical Summary

Problems solved by technology

[0003] ① Poor adaptability to walnut varieties

Due to the irregular shape of walnuts, there are large differences in their external dimensions, shell-kernel clearance, shell thickness and hardness. The shell-breaking machinery, equipment, and devices manufactured according to this idea are only suitable for walnuts of the same variety and size. When the gap is larger than the size of the walnut, some walnuts will not be shelled or only partially shelled, and the one-time shelling rate is low;

[0004] ②It is difficult to separate shell and kernel

The shape of Chinese walnut varieties is mostly non-spherical. When the size is suitable and the feeding posture is not suitable, about 20% of the walnuts will be broken along the suture line after the shell is broken by the fixed-gap extrusion sheller. The hindrance of internal septum and inner pleats prevents walnut kernels from coming out of the shell, and the kernels must be manually harvested, which increases production costs;

[0005] ③ Due to high working precision or integrated design, some cracking devices have complex structures, high manufacturing costs and difficult maintenance
