All kinds of benefits have led to the popularity and popularity of walnuts, so the increase in production is increasing.
- the fifth physical method of ultrasonic shredding is to use ultrasonic waves to shatter the shell of the walnut to achieve the separation of the shell. This method does not need to consider the size and shape of the walnut as well as the classification and positioning problems. However, due to the immaturity of the method, it is difficult to ensure that the walnut shell is shattered without causing certain damage to the walnut kernel.
- the invention consists of a frame, a transmission control device, a feeding mechanism, and a shell-breaking device.
- the frame is equipped with a shell-breaking device, which is separated from each other by a workbench.
- the impact cylinder and the clamping cylinder are arranged between the plates, and the transmission control device is arranged at the front and the lower part of the frame, and the motor and the dial and the control cam which are coaxially arranged with the motor shaft, and the active sprocket and the sheave which are set on the lower shaft,

- the disadvantage of the device is that the whole kernel rate is not high, the walnut needs to be positioned before processing, the damage to the walnut kernel is large, the processing steps are numerous, the shelling efficiency is low, and the walnut kernel is easily damaged twice, and the manufacturing cost is high.
- a shell spring positioning post the shell spring positioning post passing through a positioning hole in the piston sleeve, further comprising a piston pin perpendicular to the piston sleeve axis and connected to the piston, and further comprising a piston sleeve mounted on the piston sleeve perpendicular to the piston sleeve axis a rotating shaft, the rotating shaft is equipped with a cam cutter at one end, and the other end is a handle, and the running curve of the cam cutter rotating around the rotating shaft can push the piston pin to move back and forth in the limiting hole on the piston sleeve and contact the piston and the stopper; On the extension line of the piston central axis, the stop is fixedly mounted on the piston sleeve. Use the piston movement to hit the walnut and the block during work to achieve the purpose of breaking the shell.
- the disadvantage of this device is that the continuous reciprocating impact puts high demands on the spring.
- the walnut kernel is easily damaged, the whole kernel rate is greatly reduced, and the adaptability to walnuts of different sizes is poor.
- the centrifugal collision type shell breaking method the chemical etching method, the vacuum shell breaking method, the ultrasonic shell breaking method, and the mechanical shell breaking method.
- the first method the walnut after centrifugation hits the wall at high speed to deform the shell until it ruptures, but the broken kernels are generated after the shell is broken, so the method is not satisfactory;
- the second method the dosage of the medicament is not easy to control in actual operation, the walnut kernel It is susceptible to corrosion, and it can cause environmental pollution by poor handling. Therefore, the method is rarely applied.
- the third and fourth methods are expensive, the cost of breaking the shell is too high, and the shelling effect is not ideal.
- the fifth method the device is simple, the cost is low, and the shelling effect can be improved by improving the structure of the component, so the method is more explored and applied.
- the smashing of the tamping by the smashing method should be designed to deform the slab.
- the shape of the nut is consistent, that is, the slab must have a certain flexibility and hardness, and the coefficient of friction between the raft and the tamping should be selected to be larger to meet the requirements of the husking.
- the common domestic mechanical shelling processing equipment is classified into four categories according to the method of shelling: extrusion method, impact method, shear method and milling method.
- the cotton walnut sheller researched by Wu Ziyue uses the principle of double-toothed disc-toothed shell peeling. After the cotton walnut is fed into the shelling device, the circular toothed disc drives the cotton walnut to rotate into the gap and squeezes into the gap. The tooth tip of a certain distance continuously squeezes the surface of the walnut shell, so that the crack expands continuously, and finally the walnut shell is basically The top is completely broken, and the broken shell and walnut kernel fall down through the minimum gap.
- Zhang Zhongxin's research and development of the roller-and-eye type walnut opening machine is mainly composed of a cone-roller classifying device and a pair of roller-hole-opening devices.
- the classifying device consists of a pair of large-end, small-end, small-end tapered rollers. In composition, the gap between the two rolls gradually increases from the big end to the small end.
- the roller-and-eye opening device is a pair of cylindrical squeeze rollers of the same diameter, with a hole on the eye, and the size of the socket gradually increases from the big end to the small end.
- the two pairs of rollers are relatively rolled respectively, and the classified walnuts are broken into the corresponding sockets and then broken under the action of the two rollers, and then collected through the discharge slide.
- the centrifugal walnut secondary shell breaker developed by Wang Xiaotong [21] and others used the impact method to break the walnut. Under the friction of the pallet and the pushing action of the dial, the walnut falling on the centrifugal plate rotates together with the centrifugal plate. When the centrifugal plate reaches a certain rotational speed, the walnut will fly out at a certain speed, and the impact barrel occurs. The collision is completed and the shell is broken. By adjusting the rotation speed of the centrifugal plate, the impact force of the walnut can be adjusted, and an ideal shell-breaking effect can be obtained.
- the walnut shelling and rectifying device developed by Zhang Yong consists of a base and a top cover.
- the upper part of the base is a round table with a concave stripping chamber on the top surface and a ring of serrations on the inner edge.
- the walnut sheller developed by Chai Jinwang using the principle of friction grinding uses a toothed inner and outer mill to break the shell of the walnut.
- the outer grinding is fixed on the frame, and the inner grinding is rotated by the motor. Walnuts rupture and shell in the gap between the inner and outer grinding. After breaking to the appropriate particle size, the gap between the baffle and the inner mill bottom falls onto the blanking plate.
- the machine can not automatically adapt to the size of the walnut, and because the walnut varieties are diverse and different in size, there are certain defects in practical applications. When smashing walnuts of different sizes, it is necessary to replace the inner and outer diameters of different sizes.
- the main problems of most shellers are: low shelling rate, many stripping machines are not stripped or broken, and the shelling rate is 80% or even lower; the loss rate is high and the high dew rate is low. Due to the incomplete shell breaking, some broken walnut kernels are difficult to remove in the broken shell. Some shellers have a loss rate of 20%, while the high dew rate is about 60%. The integrity of the nuts is poor, and many shellers pursue stripping. The increase of shell ratio leads to high breaking rate of walnut kernel; the adaptability is poor. When the factors such as walnut variety, size and shell shape change, the shelling performance of shelling machine deteriorates. Most of the mechanical shell breaking equipment has a fixed gap between the shells. Because of the irregular shape of the walnuts, the walnuts are put into batches.
- Two-roll classifier the two rollers are inclined at an angle to the horizontal plane, and the two rollers are at a certain angle and relatively rotated. Due to the angle between the two rolls, the step spacing between the two rolls is gradually increased. Under the action of gravity, the walnut rolls down the seam. When the distance between the rolls is greater than the diameter of the fruit, the walnut falls from the two rolls. In the fruit slot.
- Roller type classifier the drum has several layers of drum units, each layer of the drum unit is evenly covered with small holes, the apertures in the same layer of drums have the same aperture, the apertures of different layers of rollers are different, and within each layer The aperture increases sequentially from the inside to the outside.
- the roller rolls at a constant speed the walnut is fed from the upper part of the drum, and conveyed along the outer surface of the drum. The walnuts are sequentially passed through the rollers of different apertures, and are graded from small to large.
- the shell roller device for separating the pile roller The apparatus consists of a pair of full length rollers that are in contact with each other, the outer surface of the roller being covered with a fleece, relatively rotatable and inclined with respect to a horizontal plane.
- the device When the walnut shell mixture is fed from the high end, the smooth walnut is not easily adhered by the fluff to the groove between the two rolls and slides down until it is discharged from the bottom, and the rough walnut shell is adhered by the fluff. Finally, the fleece roller is dropped into the discharge hopper.
- the device In order to achieve a certain separation effect, the device generally has a plurality of pairs of pile rollers repeatedly separated. Since the fracture ports of the walnut shell and the kernel have burrs, they can all be adhered by the pile, so the separation effect of the device is not good.
- the walnut shell kernel sorting machine developed by Dong Yuande et al. uses the wind-selection principle to separate the walnut shell kernels.
- test results show that the air volume and the length of the wind chamber have a significant effect on the shell content in the shell.
- the length of the wind chamber has a significant effect on the shell content of the kernel.
- the feed rate has a significant effect on the loss rate of the high lure.
- Liu Mingzheng and others designed and researched the rotary cage and oscillating walnut grading sieves, which can avoid the walnuts from getting stuck, and can make the walnuts with the corresponding gaps fully fall, and improve the classification efficiency and classification accuracy.
- Liu Mingzheng and others have improved the working belt in the walnut peeling and shelling device, which reduces the breaking rate of walnuts, improves the integrity of walnut kernels, reduces the loss of walnut kernels, and effectively increases the inner side and the idler. The friction between the belt and the idler prevents the smooth operation of the timing belt.
- the device comprises at least one walnut fixing mechanism and at least two impact rods arranged on the frame, the walnut shell mold has a walnut positioning hole, and the walnut shell mold
- the side wall is provided with at least two openings communicating with the positioning holes of the walnut, and the plurality of impact rods are driven by the moving mechanism to penetrate the walnuts disposed in the positioning holes of the walnut through the corresponding holes corresponding to each of the impact rods, and include
- the positioning quantitative feeding slider is arranged on both sides of the walnut positioning hole for covering the positioning hole of the walnut; the walnut positioning hole or the walnut in the walnut positioning groove is impacted by the impact rod, and the slider is set, the impact speed is fast, and the kernel is taken.
- the completeness rate is high; the invention realizes the rapid and stable feeding of the walnut by positioning the fixed-cycle reciprocating motion of the quantitative feeding slider, fully utilizes the efficiency of the machine for processing the walnut, realizes the automation and controllability of the walnut feeding, and reduces the labor cost. Improve processing efficiency.
- the shearing and squeezing force of the walnut is broken, the walnut shell is broken, the walnut kernel is exposed, and the belt is flexible, which will alleviate the walnut kernel.
- Destruction, and through the function of the flexible blade hammering system the walnut kernel embedded in the walnut shell can be further separated. Since the blade is a spiral curved surface made of a flexible material, the damage to the walnut kernel can be alleviated during the hammering process.
- the separation system automates the separation of the shells.
- the height adjustment device is adopted, so that the device can be adapted to handle different sizes of walnuts, so that it can be used in large-volume production operations, shortening labor time, saving labor, reducing processing cost, and better solving the problem of walnut peeling and shelling. Manual problems and increased shelling rate and high dew rate.
- Zhang Yanbin and others invented the two-way separation equipment of the walnut shell roller coupled with the pneumatic and flexible spiral blades.
- the walnut shell material is transported from the feeding hopper, and the walnut shell material is accelerated into the spiral hopper drum at a certain speed after being accelerated in the feeding hopper, and the walnut kernel material enters the separation area of the walnut shell kernel under the wind conveying effect, and the walnut shell material is large.
- the variable-pitch spiral conveying blade mechanism fixedly connected on the inner wall of the spiral blade drum has a spiral direction of right-handed rotation. When the spiral blade drum rotates clockwise, the spiral blade functions to transport the walnut shell material, and the material conveying direction is from the exit direction. Delivery to the import direction.
- the walnut shell material In the separation area of the walnut shell kernel, the walnut shell material is transported to the high point by the spiral blade II in the circumferential direction, while the spiral leaf II has the effect of transporting the walnut shell material to the inlet direction; after reaching a certain height, the walnut shell material is thrown from the air. Next, there is an initial velocity in the direction of the inlet. Under the action of wind power, the walnut kernels are subjected to a small wind force to fall on the walnut kernel conveying area; the walnut shell is sent to the walnut shell conveying area by a large wind force. In the walnut kernel conveying area, the walnut kernel is transported to the spiral blade drum outlet direction by the small pitch spiral blade III.
- the spiral blade III Since the spiral blade III has a small pitch and a small friction coefficient, a typical screw conveying effect is formed in this region, and the walnut kernel does not. Affected by the wind, the walnut kernel is transported by the small pitch spiral blade III to the spiral blade drum outlet direction and falls into the walnut kernel collector.
