[0045] The screening and feeding assembly 2 is used for screening and feeding the walnut according to the diameter to the corresponding position of the shell-fruit separating assembly 3, and when in use, the walnut can be directly added into the screening and feeding assembly 2 to realize automatic screening.

[0046] With reference to Figures 4-6 The shell-fruit separating assembly 3 comprises two groups of installation plates one 31 and installation plates two 32 which are symmetrically arranged upwards and downwards, a plurality of sleeve rings one 311 are rotationally arranged on the installation plate one 31, a plurality of sleeve rings two 321 are rotationally arranged on the installation plate two 32, the plurality of sleeve rings one 311 and the plurality of sleeve rings two 321 are one-to-one corresponding and are located at coaxial positions, therefore, the sleeve ring one 311 and the sleeve ring two 321 at the corresponding position each have two, the sleeve ring one 311 is located at the outer side, the two sleeve rings two 321 are located at the inner side, the inner diameter of the sleeve ring one 311 is smaller than that of the corresponding sleeve ring two 321, the installation plate one 31 and the installation plate two 32 are moved to drive the sleeve ring one 311 and the sleeve ring two 321 to move synchronously, when the two groups of symmetrically arranged sleeve rings one 311 and sleeve rings two 321 are close to each other, a spherical cavity is formed in the inside, the walnut is placed in the spherical cavity to perform the shelling operation, a plurality of shelling needles 33 are fixedly arranged on the inner walls of the sleeve ring one 311 and the sleeve ring two 321 in the radial direction, the length of the shelling needle 33 is smaller than the shell thickness of the walnut, the shelling needle 33 cannot pierce the shell of the walnut when the shelling treatment is performed, and the integrity of the kernel in the walnut is ensured.

[0047] With reference to Figure 1 and 3The screening and feeding assembly 2 comprises a separation box 21 provided with a feeding pipe 23 on one side, and an inclined separation plate 22 is arranged in the separation box 21, the separation plate 22 is in a high position at one end close to the feeding pipe 23, and the walnuts are added into the separation box 21 through the feeding pipe 23. Since the separation plate 22 at one end of the feeding pipe 23 is in a high position, the walnuts roll downwards along the separation plate 22 after entering the separation box 21, a plurality of rows of leakage holes 24 are formed in the separation plate 22, the diameters of the plurality of rows of leakage holes 24 gradually increase from high to low, when the walnuts roll along the separation plate 22, the walnuts with large diameters cannot enter the leakage holes 24 with small diameters and continue to roll downwards along the separation plate 22, and the walnuts roll downwards to the leakage holes 24 with appropriate sizes and drop through the separation plate 22, so that the walnuts are classified according to diameters through the leakage holes 24 with different sizes. A plurality of conveying pipes 25 corresponding to the leakage holes 24 are fixedly arranged below the separation plate 22, the walnuts dropping through the leakage holes 24 with the same size enter the same conveying pipe 25, the conveying pipe 25 is arranged in an inclined manner, the walnuts enter the conveying pipe 25 and roll along the conveying pipe 25, only one walnut can pass through the conveying pipe 25 at a time, and the output end of the conveying pipe 25 corresponds to the center positions of the two sleeve rings two 321. When the two sleeve rings two 321 are opened, a gap is formed between the two sleeve rings two 321 to enable the walnuts to roll in, the walnuts roll along the conveying pipe 25 and enter the lower sleeve ring two 321 and block the subsequent walnuts from continuing to roll, after the walnuts are crushed by the sleeve ring one 311 and the sleeve ring two 321, the walnut kernels are completely retained, the walnuts with small diameters after the shells are removed pass through the sleeve ring one 311 and the sleeve ring two 321 from the lower sleeve ring two 321 and the sleeve ring one 311, and the shells directly drop after being crushed, so that the subsequent walnuts continue to roll downwards and enter the sleeve ring two 321 to wait for being crushed and shelled.

[0048] The spherical cavities formed by the plurality of groups of the sleeve ring one 311 and the sleeve ring two 321 have diameters consistent with the sizes of the corresponding leakage holes 24, so that the walnuts entering the spherical cavities can be matched with the sizes of the spherical cavities, and the shells of the walnuts are successfully removed.

[0049] The shell-kernel separation assembly 3 further comprises a control mechanism for driving the two groups of mounting plates one 31 and mounting plates two 32 to open and close, the mounting plates one 31 and mounting plates two 32 reciprocate to open and close under the action of the control mechanism, the mounting plates one 31 and mounting plates two 32 located above are driven upwards while the mounting plates one 31 and mounting plates two 32 located below move downwards, when the two groups of mounting plates one 31 and mounting plates two 32 approach each other, the shell-kernel separation assembly 3 is provided with a plurality of groups of the sleeve ring one 311 and the sleeve ring two 321, the sleeve ring one 311 and the sleeve ring two 321 are arranged in a circular cavity, the sleeve ring one 311 and the sleeve ring two 321 are arranged in a circular cavity, and the sleeve ring one 311 and the sleeve ring two 321 are arranged in a circular cavity.

[0050] Referring to Figures 7-8The control mechanism comprises the driving frame 36 for driving the first mounting plate 31 and the second mounting plate 32 to move up and down and the cylinder 34 arranged horizontally for driving the two driving frames 36 at the two up and down positions to move reversely to realize the opening and closing.

[0051] The driving frame 36 is vertically slidably arranged in the outer box body 1, a plurality of positioning rods 11 are vertically arranged in the outer box body 1, the driving frame 36 is provided with a positioning hole 362, the positioning hole 362 is slidably connected with the positioning rod 11, the positioning rod 11 and the positioning hole 362 are guided in cooperation to ensure the stability of the driving frame 36 during movement, and the driving frame 36 is connected with the first abutting structure between the first mounting plate 31, so that the driving frame 36 has a buffer displacement when driving the first mounting plate 31 to move, so that the first mounting plate 31 can be pulled apart by a larger distance when being opened to ensure that the walnut shell is peeled off.

[0052] Referring to Figures 7-8 , the cylinder 34 is fixedly arranged on the inner wall of the outer box body 1, and the telescopic end of the cylinder 34 is fixedly provided with a guide frame 35, the cylinder 34 drives the guide frame 35 to move when being telescoped, referring to Figures 9-10 , the movement direction of the guide frame 35 is perpendicular to the movement direction of the driving frame 36, the guide frame 35 is provided with two symmetrically arranged guide openings 351, and the driving frame 36 is fixedly provided with a guide column 361, the guide column 361 extends into the guide opening 351 and abuts against the inner wall of the guide opening 351, the driving frame 36 can only slide up and down under the limiting action of the positioning rod 11, therefore, when the guide frame 35 moves transversely, the guide opening 351 abuts against the guide column 361 to drive the driving frame 36 to move, the guide column 361 needs to change the longitudinal position along the contour change of the guide opening 351, the two guide openings 351 on the guide frame 35 are arranged obliquely, so that the two guide openings 351 form a "V" type structure, since the two guide openings 351 are symmetrically and obliquely arranged, when the guide frame 35 moves in the direction of opening of the guide opening 351, the two guide columns 361 gradually approach each other to drive the driving frame 36 to approach each other, when the guide frame 35 moves in the direction of convergence of the guide opening 351, the two guide columns 361 move away from each other to drive the driving frame 36 to move away from each other, thereby realizing the opening and closing of the first mounting plate 31 and the second mounting plate 32.

[0053] The second abutting structure is arranged between the first mounting plate 31 and the second mounting plate 32, so that the first mounting plate 31 has a buffer displacement when driving the second mounting plate 32 to move, so that the first mounting plate 31 and the second mounting plate 32 can be pulled apart by a larger distance when being opened to ensure that the walnut shell is peeled off.

[0054] Referring to Figure 4 , 7The mounting plate 31 is equipped with a drive mechanism for rotating the first collar 311 and the second collar 321. After the shell-breaking needle 33 cuts through the walnut shell, the first collar 311 and the second collar 321 maintain the covering state of the walnut. At this time, the drive mechanism controls the first collar 311 and the second collar 321 to rotate in opposite directions. The multiple collars 311 transmit power to each other. When the drive mechanism drives one of the collars 311 to rotate, the multiple collars 311 rotate synchronously. The two collars 321 are mutually driven. When the drive mechanism drives one of the collars 321 to rotate, multiple collars 321 rotate synchronously. When the collars 311 and 321 rotate in opposite directions, the shell-breaking needles 33 on the collars 311 and 321 apply a force in the opposite direction to the walnut shell, scratching weft lines on the outer wall of the walnut. When the collars 311 and 321 stop rotating, the position of the shell-breaking needles 33 is misaligned with the warp lines. (Refer to...) Figure 11 Because the shell of the walnut is marked with a grid of warp and weft lines by the shell-breaking needle 33, the connection strength of the walnut shell in the warp and weft line section is weaker than that of the intact part. When the two sets of ring one 311 and ring two 321 are separated, a certain distance is pulled between ring one 311 and ring two 321. The shell of the walnut is pulled outward by the shell-breaking needle 33 until the shell of the walnut breaks along the warp and weft lines, exposing the intact walnut kernel.

[0055] Reference Figure 6 and 12, the walnut is approximately circular, the mounting plate one 31 and the mounting plate two 32 drive the ring one 311 and the ring two 321 to move up and down along the vertical direction, the positions of the two sets of ring one 311 and ring two 321 do not exceed the central cross-sectional position of the walnut, in the peeling process, the pulling force F1 applied by the shell breaking needle 33 to the walnut shell is vertical, there is a brown, lignified, sheet-shaped or net-shaped connection between the walnut shell and the kernel, also called the walnut diaphragm, when the walnut is shelled, the diaphragm is mainly separated from the kernel, the shell breaking needle 33a on the ring two 321 and the weft mark W1 have the contact point A, in the pulling process, the weft mark W1 is first broken, then tears from the weft mark W1 to the weft mark W2, the force point position changes from the weft mark W1 to the weft mark W2 constantly, and finally the force point is the weft mark W2, there is an angle between the tangent L1 of the shell of the force-bearing part of the walnut and the pulling force F1, since the walnut shell is approximately spherical, in the tearing process, the force F1 acting on the walnut shell is the radial outward force of the walnut, and according to the force analysis, it can be obtained that the radial outward force of the walnut is regarded as the component force f1 towards the outside of the walnut, the shell breaking needle 33b on the ring one 311 and the weft mark W2 have the contact point B, the plurality of shell breaking needles 33b apply the outward pulling force F2 to the outside of the weft mark W2, and take the end point of the walnut as the force point, there is an angle between the tangent L2 of the shell of the force-bearing part of the walnut and the pulling force F2, and according to the force analysis, it can be obtained that the component force f2 generated by the pulling force F2 is also towards the outside of the walnut, so that no pressure is generated to the inside of the walnut in the shelling process, while the walnut is shelled, the broken shell is peeled away from the walnut kernel, compared with the existing technology of shelling the walnut by extrusion, the integrity of the walnut kernel can be maximally preserved, and the shelling effect of the walnut is improved.

[0056] With reference to Figures 13-14 , the first abutting structure comprises a guide rod one 363 fixedly arranged on the driving frame 36, two stop sheets one 364 are fixedly arranged on the guide rod one 363, the mounting plate one 31 is slidably connected with the guide rod one 363 and located between the two stop sheets one 364, a spring one is arranged between the stop sheet one 364 close to the driving frame 36 and the mounting plate one 31, in the initial state, the spring one is in the elongated state, pushes the mounting plate one 31 to abut against the stop sheet one 364 away from the driving frame 36, when the walnuts are surrounded and combined, the ring one 311 abuts against the walnuts, so that the mounting plate one 31 is blocked, until the spring one is compressed to the limit position, the stop sheet one 364 close to the driving frame 36 and the mounting plate one 31 are effectively driven, at this time, the shell breaking needle 33 is broken to form the weft mark under the action of the thrust force.

[0057] With reference to Figures 13-14The second abutting structure comprises a guide rod two 313 fixedly arranged on the mounting plate one 31, two blocking pieces two 312 fixedly arranged on the guide rod two 313, the mounting plate two 32 slidably connected with the guide rod two 313 and located between the two blocking pieces two 312, and a spring two arranged between the blocking piece two 312 close to the mounting plate one 31 and the mounting plate two 32. In the initial state, the spring two is in the elongated state, and the mounting plate two 32 is pushed to abut against the blocking piece two 312 away from the mounting plate one 31. When the walnut is surrounded and combined, the collar two 321 abuts against the walnut, so that the mounting plate two 32 is blocked until the spring two is compressed to the limit position, the blocking piece two 312 close to the mounting plate one 31 and the mounting plate two 32 are effectively driven, and at this time, the hull breaking needle 33 is broken to form the weft mark under the action of the thrust.

[0058] When the mounting plate one 31 and the mounting plate two 32 are separated, the hull breaking needle 33 is clamped into the weft mark on the walnut shell, so that when the driving frame 36 moves outward, the spring one is first reset, and when the blocking piece one 364 close to the driving frame 36 abuts against the mounting plate one 31, the mounting plate one 31 is pulled outward, the shell at the end of the walnut is broken, the collar one 311 is no longer limited by the walnut, the driving frame 36 continues to move outward, the spring two is reset, and when the blocking piece two 312 close to the mounting plate one 31 abuts against the mounting plate two 32, the mounting plate two 32 is pulled outward, and the mounting plate one 31 and the mounting plate two 32 are pulled apart by a certain distance, so that the shell in the middle of the walnut is broken, and the shelling is completed.
