Description

A hickory winnowing type shell and kernel separation device

technical field

The utility model relates to a hickory nut shell breaking device, in particular to a hickory nut winnowing type shell kernel separation device.

Background technique

In recent years, due to the high nutritional value and unique taste and flavor of pecan nuts, it has gradually been recognized by consumers and has become a popular high-end nut. At the same time, hickory nuts can be used to make activated carbon, natural plant fuel, extract tannin, etc., and have high economic value. Therefore, breaking the shell of hickory nuts to extract kernels can greatly increase the added value of hickory nuts.

At present, the best-selling variety in the international market that has been commercially cultivated on a large scale is American hickory. Since 1948, more than 80% of American pecans have been sold in the form of nuts. Some large pecan shelling factories have more than 10 hickory shelling and kernel production lines. The processing of pecans is basically an automatic or semi-automatic assembly line. Production, capable of processing 150,000 pounds of pecans per day, reaching 30 million pounds in a mature season. In my country, there are not many studies on the mechanical structure of hickory nut shelling and kernel extraction. Currently, the hickory nut kernels sold in the market are basically separated and screened by manual smashing.

The separation of shell and kernel of hickory nut material after shell breaking is an important process before the deep processing of hickory nut kernel. Research, development and design of a mechanical device for separating shell and kernel of hickory nut material is an urgent problem to be solved.

The plate is inclined, the upper edge is hinged with the frame, the lower end is connected with the frame through a spring, the support frame is connected to the back of the vibrating plate, the lower end of the support frame is provided with a bearing, and the frame is provided with a rotatable drive cam, and the drive cam wheel surface is in contact with the frame. The bearings are contacted and connected, and a collection box is arranged in the downward direction of the vibrating plate, and a blowing port is arranged between the collecting box and the vibrating plate, and the blowing port is connected with the fan.

The collection box is arranged under the vibrating plate, and within the range where the shell kernels are blown off, the collection box is divided into multiple collection chambers according to the distance from the vibrating plate.

The vibrating plate is a square plate, and guard edges are provided on both sides of the vibrating plate to guide the falling materials to prevent splashing outside; further, the non-smooth surface of the vibrating plate is provided with stepped protrusions to prevent After the material slides down, the falling speed is too fast, which is not conducive to blowing and separating.

The hickory material falls on the vibrating plate through the discharge port, and the vibrating plate is driven by the motor through the belt to drive the cam to rotate, so that the vibrating plate vibrates up and down, so that the hickory kernels and shells are loosened and separated, and are thrown out under the vibration of the vibrating plate , through the airflow at the blowing port, the shells and kernels of different weights are blown and dropped into different collection boxes.

The beneficial effects of the utility model are:

The utility model is based on the analysis of the various components of the hickory material after shelling and the research on the movement state of the hickory material in the air flow after the shelling, and proposes a design scheme of the hickory winnowing type shell and kernel separation mechanism. The land selection method is used to separate the ground walnut kernels and shell kernels after shell breaking, which has high production efficiency, effectively reduces the labor intensity of workers, and significantly improves social benefits.

detailed description

The utility model is described in detail below in conjunction with accompanying drawing:

The utility model proposes a hickory winnowing type shell kernel separation mechanism, as shown in Figure 1, the numbers in the accompanying drawings are respectively: in Figure 1, 1-frame, 2-feeding opening, 3-vibrating plate, 4-bearing, 5-fan, 6-collecting box, 7-air outlet, 8-driving cam, 9-spring.

As shown in the figure, the hickory winnowing type shell kernel separation mechanism includes a frame 1, a blanking port 2, a vibrating plate 3, a driving cam 8, a fan 5, and a collection box 6, and the blanking port 2 is arranged above the frame 1. , a vibrating plate 3 is set directly below the blanking port 2, and the swing angle range of the vibrating plate 3 is set to 35°~50°. For the reset operation of the vibrating plate 3, the vibration frequency of the vibrating plate 3 is kept stable. The back of the vibrating plate 3 is connected with a bracket, the lower end of the bracket is provided with a bearing 4, and the frame is provided with a rotatable driving cam 8, and the driving cam 8 wheel surface It is in contact with the bearing 4, and a collection box 6 is provided in the downward direction of the vibrating plate 3, and a blowing port 7 is arranged between the collecting box 6 and the vibrating plate 3, and the blowing port 7 is connected with the fan 5, and the height of the blowing port is between the vibration between the board and the collecting box.

The hickory nut shell kernel material that has undergone the grading and shell breaking process falls to the vibrating plate 3 through the discharge port 2, so that the hickory nut shell kernel material collides with the vibrating plate 3, so that the hickory nut kernel and the shell are separated, and the vibrating plate 3 is driven by the cam. 8 is driven by the motor through the belt and vibrates under the action of the spring 9, so that the hickory nut shell material is thrown out under the vibration of the vibrating plate 3, and under the action of the airflow of the fan 5 through the blowing port 7, due to the hickory shell kernel The suspension speeds of the materials in the airflow are different, and the hickory nut shell and kernel materials are separated and fall into the collection bins of different collection boxes 6 .

The hickory nut material after shelling is thrown out under the action of the vibrating plate, and under the action of the stable airflow provided by the fan, it is separated due to the difference in the suspension speed of each component of the hickory nut shell kernel mixture material in the airflow. Under the action of the vibration of the vibrating plate, it is helpful to disperse the shell kernel in the material, so that the minimum fluidization velocity becomes smaller, thereby reducing the air demand. The hickory nut shell and kernel mixture material after shelling falls from the feeding port, and hits the vibrating plate when it goes up on the vibrating plate, so that the hickory nut shell kernel material can pop out after the impact, ensuring that the hickory nut shell kernel is in a fluidized state; The air velocity for the separation of the various components of the walnut material is selected from the 4-72 type 2.5A fan, the air volume is 805~1677m ³ /h, the maximum flow rate is 0.21m ³ /s, the speed is 2900r/min, and the power is 0.75kW.

The utility model has the advantages of:

The utility model is based on the analysis of the various components of the hickory material after shelling and the research on the movement state of the hickory material in the air flow after the shelling, and proposes a design scheme of the hickory winnowing type shell kernel separation mechanism, so that after classification The hickory nut shell kernel mixture material after shelling completes the separation of hickory nut shell kernel to achieve high productivity. Reduce labor intensity, improve health conditions, and significantly increase social benefits.
