[0001] The present invention relates to the technical field of walnut shell breaking and separation, and specifically to a bionic and efficient walnut shell breaking and kernel separation device. Background Art

[0002] Using mechanical equipment to break the shells of walnuts and separate the kernels is the development trend. However, current processing equipment often first uses a drum sieve to screen walnuts by size, then the large and small walnuts enter different funnels, and then pass through the bottom holes of the funnels into a squeezing shaft with semi-circular grooves for circular squeezing and shell breaking. Its structure and processing logic are relatively complex, and it cannot achieve bionic shell breaking of walnuts with a more ingenious structure.

[0003] Therefore, it is necessary to provide a bionic and efficient walnut shell breaking and kernel separation device to solve the problems raised in the above background art. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solution: A bionic and efficient walnut shell breaking and kernel separation device, including a shell breaking bin, a first shell breaking roller group, and a squeezing plate. Among them, at least one group of the first shell breaking roller group is arranged in the shell breaking bin. The first shell breaking roller group includes a first roller body and a second roller body that are symmetrically arranged and rotatably arranged in the shell breaking bin. There is a rotational speed difference between the first roller body and the second roller body. A through groove corresponding to the gap between the first roller body and the second roller body is also opened on one side of the shell breaking bin. A synchronous shaft is rotatably arranged outside the shell breaking bin, and a squeezing plate corresponding to the through groove is fixed on the synchronous shaft.

[0005] Further, as a preference, at least one group of second shell breaking roller groups is also arranged in the shell breaking bin. The second shell breaking roller group is located below the first shell breaking roller group. The structure of the second shell breaking roller group is the same as that of the first shell breaking roller group, and the gap between the first roller body and the second roller body in the second shell breaking roller group is smaller than the gap between the first roller body and the second roller body in the first shell breaking roller group.

[0006] Further, as a preference, the sides of the first roller body and the second roller body away from the squeezing plate are higher than the sides of the two close to the squeezing plate.

[0007] Further, as a preference, 2 - 5 squeezing plates are circumferentially arranged at the position of the synchronous shaft corresponding to the through groove.

[0008] Further, as a preference, the bottom of the shell breaking bin is communicated with a separation trough through a material guiding trough. A conveyor belt is embedded at the bottom of the separation trough. A blanking trough is arranged on one side of the separation trough, and a blower is embedded on the other side. An aggregate port is opened below the side of the separation trough close to the blower, and an aggregate trough is arranged below the aggregate port.

[0009] Furthermore, preferably, the conveyor belt includes a mounting base, in which two symmetrically arranged rotating wheels are rotatably provided. A belt body is drivingly connected between the two rotating wheels. An oscillator is further provided on the mounting base, and the output end of the oscillator can contact the belt body located above.

[0010] Furthermore, preferably, one side of the conveyor belt is hinged to the separation tank, and the other side of the conveyor belt is hinged to the telescopic column, and the other end of the telescopic column is supported on the ground.

[0011] Furthermore, preferably, the first roller body and the second roller body have the same structure, and both include a rotating shaft, a ring shaft, a support block and a semi-ring body. Among them, the rotating shaft is rotatably provided in the shell-breaking bin and has power. A ring shaft is sleeved outside the rotating shaft, and a sealing cavity is formed between the ring shaft and the rotating shaft.

[0014] Compared with the prior art, the present invention provides a bionic and efficient walnut shell-breaking and kernel-shell separation device, which has the following beneficial effects:

[0015] 1. In the embodiment of the present invention, on the one hand, the rotation of the first roller body and the second roller body is used to break the shell of the walnut. On the other hand, the extrusion plate can effectively feed the walnut between the first roller body and the second roller body, and make the walnut always have a downward movement trend. Moreover, there is a rotational speed difference between the first roller body and the second roller body, so that the action of manually rubbing the walnut to break the shell can be simulated.

[0016] 2. In the embodiments of the present invention, since the gap between the first roller body and the second roller body in the second shell-breaking roller group is smaller than the gap between the first roller body and the second roller body in the first shell-breaking roller group, the screening of walnuts can be achieved through the first shell-breaking roller group and the second shell-breaking roller group, so that walnuts with qualified particle sizes are shelled by the corresponding first shell-breaking roller group or second shell-breaking roller group; that is, its screening and shell-breaking are integrated designs.

[0017] 3. In the embodiments of the present invention, when using the protrusions to squeeze walnuts, the protrusions tend to be pushed towards the direction of the rotating shaft by the reaction force of the walnuts. The external thread is located on the side of the internal thread close to the sealing cavity, and there is no interference between the external thread and the internal thread, and neither of them will be damaged; when the rotating shaft rotates, a restriction will be generated between the external thread and the internal thread to prevent the protrusion assembly from detaching from the ring shaft;

[0018] 4. In the embodiments of the present invention, while using the protrusions to squeeze walnuts, the sphere in the sealing cavity shakes under the drive of the ring shaft, thereby hitting the offset column so that the hemispherical body can perform micro-vibrations on the broken walnut shells, making it easier to separate from the walnut kernels.

[0026] Embodiment: Please refer to Figures 1 to 6 , in the embodiment of the present invention, a bionic high-efficiency walnut shell-breaking and kernel-shell separation device includes a shell-breaking bin 1, a first shell-breaking roller group 2 and an extrusion plate 5. Among them, at least one group of the first shell-breaking roller group 2 is arranged in the shell-breaking bin 1. The first shell-breaking roller group 2 includes a first roller body and a second roller body that are symmetrically arranged and rotatably arranged in the shell-breaking bin 1. There is a rotational speed difference between the first roller body and the second roller body. A through groove 4 corresponding to the gap between the first roller body and the second roller body is also opened on one side of the shell-breaking bin 1. An extrusion plate 5 corresponding to the through groove 4 is fixed on the externally rotatable synchronous shaft 6 of the shell-breaking bin 1.

[0027] That is to say, in this embodiment, on the one hand, the shell-breaking of walnuts is realized by the rotation of the first roller body and the second roller body. On the other hand, the extrusion plate 5 can effectively feed the walnuts between the first roller body and the second roller body, and make the walnuts always have a tendency to move downward. Moreover, there is a rotational speed difference between the first roller body and the second roller body, so that the action of manually rubbing the walnuts to break the shells can be simulated.

[0028] As a preferred embodiment, at least one group of second shell-breaking roller groups 3 is also arranged in the shell-breaking bin 1. The second shell-breaking roller group 3 is located below the first shell-breaking roller group 2. The structure of the second shell-breaking roller group 3 is the same as that of the first shell-breaking roller group 2, and the gap between the first roller body and the second roller body in the second shell-breaking roller group 3 is smaller than the gap between the first roller body and the second roller body in the first shell-breaking roller group 2.

[0029] It should be explained that since the gap between the first roller body and the second roller body in the second shell-breaking roller group 3 is smaller than the gap between the first roller body and the second roller body in the first shell-breaking roller group 2, the screening of walnuts can be realized through the first shell-breaking roller group and the second shell-breaking roller group, so that the walnuts with qualified particle sizes are shell-broken by the corresponding first shell-breaking roller group or second shell-breaking roller group; that is, its screening and shell-breaking are integrated designs;

[0030] Furthermore, it should be noted that, during implementation, a third shell-breaking roller group, a fourth shell-breaking roller group, etc. may also be configured in the shell-breaking bin 1;

[0031] As a preferred embodiment, the sides of the first roller and the second roller away from the extrusion plate 5 are higher than the sides thereof close to the extrusion plate 5 .

[0032] During multiple debugging, it was found that when the squeezing plate 5 is used for feeding, its length should be consistent with the length of the first roller body and the second roller body, or even slightly longer than the first roller body and the second roller body, so that the walnuts at each position can be squeezed by the squeezing plate;

[0033] At this time, the length of the extruded plate is longer and its stability is worse;

[0034] Therefore, the following improvements are made in this embodiment: the side of the first roller and the second roller away from the extrusion plate 5 is higher than the side of the two rollers close to the extrusion plate 5, so that the walnuts can gather toward the extrusion plate, and the length of the extrusion plate does not need to be configured to be consistent with the length of the first roller and the second roller, thereby ensuring the stability of feeding.

[0035] As a preferred embodiment, there are 2 to 5 extrusion plates 5 in a circular array at the position of the synchronization shaft 6 corresponding to the through slot 4.

[0036] In this embodiment, the bottom of the shell breaking bin 1 is connected to the separation trough 8 by a material guide trough 7, a conveyor belt 9 is embedded in the bottom of the separation trough 8, a material discharge trough 12 is provided on one side of the separation trough 8, and a blower 10 is embedded on the other side. A material collection port is opened below the side of the separation trough 8 close to the blower 10, and a material collection trough 13 is provided below the material collection port.

[0037] In addition, the conveyor belt 9 includes a mounting base 91, in which two symmetrically arranged wheels 92 are rotatably arranged, and a belt body 93 is transmission-connected between the two wheels 92. An oscillator is also arranged on the mounting base 91, and the output end of the oscillator can contact the belt body 93 located above.

[0038] In addition, one side of the conveyor belt 9 is hinged to the separation trough 8, and the other side of the conveyor belt 9 is hinged to the telescopic column 11, and the other end of the telescopic column 11 is supported on the ground.

[0039] In this embodiment, different friction coefficients, wind resistance coefficients, vibrations, etc. are used to separate walnut shells and kernels. The different friction coefficients of walnut shells, kernels and contact surfaces are used to show different motion states under the action of vibration and airflow. The walnut kernels move downward toward the inclined plane, and the shells are relatively light. Under the action of vibration and force component, they move upward against the inclined plane to achieve shell-kernel separation.

[0040] In this embodiment,Figure 5 and 6 The structures of the first roller body and the second roller body are the same, and both include a rotating shaft 21, a ring shaft 22, a support block 23, and a semi-ring body 24. Among them, the rotating shaft 21 is rotatably arranged in the shell-breaking bin 1 and has power. A ring shaft 22 is sleeved outside the rotating shaft 21. A sealing cavity is formed between the ring shaft 22 and the rotating shaft 21. A plurality of support blocks 23 fixed between the rotating shaft 21 and the ring shaft 22 are arranged in the sealing cavity. Two semi-ring bodies 24 which are symmetrically arranged and detachable are further arranged outside the ring shaft 22. A flexible pad 25 is attached to the outside of the semi-ring body 24, and a protrusion assembly 26 is further arranged on the flexible pad 25.

[0041] To improve the adaptability of the device, in this embodiment, two semi-ring bodies 24 are configured. The inner diameter of the semi-ring body 24 matches the outer diameter of the ring shaft 22, and the outer diameter of the semi-ring body 24 can be specifically configured according to the actual situation. That is, semi-ring bodies 24 of multiple specifications can be prepared in advance, so that the distance between the first roller body and the second roller body can be adjusted;

[0042] The support block 23 can be integrally formed on the inner side of the ring shaft 22. The support block 23 can be distributed along the axial direction of the ring shaft 22. The support block 23 and the rotating shaft 21 can be fixedly connected by means of threaded connection;

[0043] By configuring the protrusion assembly 26, the shell-breaking efficiency of walnuts can be improved.

[0044] Specifically, the protrusion assembly 26 includes a column body 261 and a protrusion 262. Among them, the column body 261 can sequentially slide through the flexible pad 25, the semi-ring body 24, and the ring shaft 22 and then extend into the sealing cavity. A protrusion 262 is arranged at one end of the column body 261 away from the sealing cavity. External threads 266 are also arranged on the outer surface of the column body 261. A through hole is formed in the ring shaft 22 for the column body to pass through. Internal threads are arranged on the inner surface of the through hole;

[0045] When one end of the column body 261 extends into the sealing cavity, the external threads are located on the side of the internal threads close to the sealing cavity.

[0046] When using the protrusion 262 to squeeze the walnut, the protrusion 262 has a tendency to be pushed towards the direction of the rotating shaft 21 by the reaction force of the walnut. The external threads are located on the side of the internal threads close to the sealing cavity, and there will be no interference between the external threads and the internal threads, and neither of them will be damaged.

[0047] When the rotating shaft 21 rotates, a restriction will be generated between the external threads and the internal threads;

[0048] As a preferred embodiment, a displacement post 263 is connected to the middle of the cylinder 261 by a reset ring gasket 264. Both ends of the displacement post 263 extend out of the cylinder 261, and a hemisphere 265 is provided at the end far from the sealing cavity. A sphere is loaded into the sealing cavity.

[0049] While squeezing the walnut by means of the protrusion 262, the sphere in the sealing cavity shakes under the drive of the ring shaft 22, so as to impact the displacement post 263, enabling the hemisphere to perform micro-vibration on the broken walnut shell, and thus making it easier to separate from the walnut kernel.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
