The first vibrating screen 1 is positioned at the bottom end of the first screen cloth 101 and is communicated with the feed inlet end of the horizontal rolling screen 2 through a second conveying device 5.

As shown in fig. 2, the horizontal type rolling screen 2 includes a cylindrical inner mesh 201 disposed obliquely downward. The screen mesh aperture of cylinder inner mesh screen 201 is K2, and its top feed inlet end communicates with second conveyer 5, and bottom discharge gate end communicates with abandonment silo through third conveyer 6. The cylindrical inner mesh screen 201 is externally sleeved with an outer mesh screen 202. The outer screen 202 is composed of two cylindrical first outer screens 2021 having a screen aperture K3 and a second outer screen 2022 having a screen aperture K4. The horizontal type rolling screen 2 is provided with a first collector 204 for collecting the screened objects of the inner screen 201 and the outer screen 202 and a second collector 205 for collecting the screened objects between the inner screen 201 and the outer screen 202.

And the discharge end of the first conveying device 4 is communicated with the second vibrating screen 3 through a second lifting machine 8.

The second vibrating screen 3 includes: a second screen 304 and a third screen 305 arranged in parallel up and down and inclined downwards. The second screen 304 has a hole diameter K5, and the third screen 305 has a hole diameter K6. The screen of the second vibrating screen 3 is supplied to the oil press through a mixing pipe 10.

At this moment, the crushed juglans sigillata materials are firstly screened by the first vibrating screen 101 in the first vibrating screen 1, the materials on the screen partially enter the horizontal rolling screen 2, and the screened materials enter the first conveying device 4. The material fraction is then screened a second time in the horizontal roller screen 2, first between the top of the inner screen 201 and the first outer screen 2021, and the screen material falls through the first collector 204 into the first conveyor 4. Then, the third screening is completed between the inner mesh screen 201 and the first outer mesh screen 2021, the screened material between the inner mesh screen 201 and the first outer mesh screen 2021 enters the first lifting machine 7 through the second collector 205, and the screened material enters the first transportation device 4 through the first collector 204.

With the arrangement, on one hand, materials blocked at the mesh openings of the screen of the horizontal type rolling screen 2 can be blown into the screen by the air flow blown by the air blower 206, so that the problem of screen blockage is solved. On the other hand, because the viscidity of the walnut kernel can lead to adopting the roll screen alone and can not separating the shell benevolence of the walnut completely, have some walnut kernels to adhere on the shell to by the transport of third conveyer 6 to abandonment material storehouse, lead to appearing the material extravagant. The blower 206 designed by adopting the specific combination form and the position and the orientation of the air outlet of the invention ensures that the airflow entering the horizontal rolling screen 2 is in a vortex shape, thereby driving the juglans sigillata to continuously roll with high strength, further separating the walnut kernels adhered to the shell, improving the efficiency of separating the juglans sigillata shells and kernels, and avoiding the walnut kernels from being carried into a waste material bin by the walnut shells to cause waste.

In addition, when the crisp walnut extracts oil, often only need to break to the walnut-meat of certain mesh number can accomplish and extract oil, but if the walnut-meat adopted the walnut-meat to extract oil completely, it is very easy to appear that the material piles up at the oil press feed inlet and does not get into the mechanism part that extracts oil to lead to the condition that oil press operating condition is relatively poor, even is down. Therefore, the applicant designs a shell and kernel separating device with a unique screening mechanism and a specific screen mesh size in particular to obtain walnut kernels and walnut shell material components with required specific particle sizes, so that a pecan oil pressing material in a specific combination form can be obtained, and continuous oil pressing of the oil press on the pecan oil pressing material is realized.

The research of the applicant finds that the walnut and the walnut have obvious technical difference when oil is pressed, and the existing walnut oil pressing process is adopted, so that the oil press can be seriously blocked by adopting pure walnut kernels, and the oil press is usually stopped to clean materials when the oil press is started and the oil press is not enough for 20% of the continuous working time of the oil press design. Therefore, the applicant proposes the method of tertiary screening of the invention, selects specific components and compositions through tertiary screening, and combines a material controller to mix the compositions in a specific mass ratio to form the oil-pressing material.

As shown in fig. 5, the sixth transportation device 3073 or the fifth transportation device 3072 is provided with a laser grating sensor 908 near the material chamber 901, in the pecan shell and kernel separation control device shown in embodiment 6.

The signal output end of the laser grating sensor 908 is in signal connection with the signal input end of the microprocessor 11. The signal output end of the microprocessor 11 is in signal connection with the control signal input end of the second electromagnetic valve 907. When the microprocessor 11 receives the grating full-shading signal continuously sent by the laser grating sensor 908, it controls the second electromagnetic valve 907 to open for a preset time.

The design is mainly used for monitoring the loading amount of materials in the material cabin 901, and when the material cabin 901 is fully loaded, the grating surface of the laser grating sensor 908 can be blocked, so that a grating full-shielding signal continuously emitted by the laser grating sensor 908 is caused. At this time, the microprocessor 11 controls the second solenoid 907 to open for a predetermined time, so as to release the excessive materials in the material chamber 901 into the waste collector.

Example 8

As shown in fig. 5, two electric push rods 910 are symmetrically disposed outside the material chamber 901 of the hickory nut shell and kernel separation control device in embodiment 7. The control signal input end of the electric push rod 910 is connected with the signal of the microprocessor 11. At this time, when the microprocessor 11 receives the grating full-shading signal continuously emitted from the laser grating sensor 908, the following control and judgment are performed:

s1, controlling the two electric push rods 910 to perform rapid synchronous reverse reciprocating motion for a preset time.

And S2, if the grating full-shielding signal sent by the laser grating sensor 908 disappears, the step S4 is executed. If the grating full-shading signal from the laser grating sensor 908 does not disappear, the process proceeds to step S3.

And S3, controlling the second electromagnetic valve 907 to be opened for a preset time, and then entering the step S4.

And S4, terminating.

Since the material is fed into the material chamber 901 from the discharging end of the sixth transporting device 3073 or the fifth transporting device 3072, the material is easily formed into a pyramid shape in the material chamber 901 below the discharging end of the sixth transporting device 3073 or the fifth transporting device 3072, and at this time, when the tip of the pyramid enters the sixth transporting device 3073 or the fifth transporting device 3072, the grating full-shielding signal continuously emitted by the laser grating sensor 908 is also caused. However, the material compartment 901 does not necessarily reach the full load standard, and the dumping of the material may result in unnecessary waste of the material. By adopting the arrangement, when the grating full-shielding signal continuously sent by the laser grating sensor 908 is triggered for the first time, the pyramid-shaped material stacking structure is destroyed by firstly shaking the material cabin 901 from left to right, so that the pyramid-shaped material stacking structure tends to be tiled under the action of inertia, and unnecessary material waste is avoided.

It is to be noted and understood that various modifications and improvements can be made to the invention described in detail above without departing from the spirit and scope of the invention as claimed. Accordingly, the scope of the claimed subject matter is not limited by any of the specific exemplary teachings given.
