The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a walnut shell separation and screening device for processing walnuts. Figure 1-3 As shown, the shell and kernel separation and screening device for walnut processing includes: a separation box 1 fixedly installed with a feed hopper 2; a guide plate 3, the guide plate 3 is hinged in the separation box 1 and is arranged corresponding to the feed hopper 2; a support plate 4, the support plate 4 is fixedly installed in the separation box 1; a separation frame 5, the separation frame 5 is arranged on the support plate 4 and is arranged corresponding to the guide plate 3; a first screen 6, the first screen 6 is fixedly installed on the separation frame 5; a second screen 7, the second screen 7 is fixedly installed on the support plate 4 and is arranged corresponding to the first screen 6; a bump 8, the bump 8 is fixedly installed on the separation frame 5 and is arranged corresponding to the first screen 6; a collecting box 9, the collecting box 9 is arranged in the separation box 1 and is arranged corresponding to the first screen 6 and the second screen 7; a traction mechanism, the traction mechanism is arranged on the support plate 4 to drive the separation frame 5 to vibrate and screen walnuts.

[0021] In this embodiment, the feed hopper 2 and the guide plate 3 are responsible for introducing the walnuts to be separated into the separation box 1, and the setting of the guide plate 3 helps the walnuts to enter smoothly and be initially guided. The support plate 4 provides stable support for the entire device, and the separation frame 5 is responsible for carrying the walnuts and separating the shells and kernels. The complete walnut shells and walnut kernels are discharged and separated through the opening at one end of the separation frame 5. The first screen 6 and the second screen 7 pass through the mesh to separate the fine walnut kernels and walnut shells. The broken walnut kernels and walnut shells fall into the collection box 9 through the first screen 6 and the second screen 7. The setting of the protrusion 8 helps to block the fine walnut kernels and walnut shells when the separation frame 5 vibrates, so as to screen more effectively. The collection box 9 is used to collect the fine walnut debris screened by the screen, which is convenient for subsequent collection and processing. The traction mechanism is arranged on the support plate 4, which is used to drive the separation frame 5 to vibrate, so as to achieve the screening of walnuts. Compared with the traditional manual screening, this vibration screening method not only improves the screening efficiency, but also can better separate the broken walnut kernels and walnut shells.

[0022] In a further preferred embodiment of the utility model, the traction mechanism includes a fixed block 10, a connecting block 11, a spring 12, a traction rope 13, a guide wheel 14 and a driving mechanism, the fixed block 10 is fixedly mounted on the support plate 4, the connecting block 11 is fixedly mounted on the separation frame 5 and slides through the support plate 4, the spring 12 is fixedly mounted between the fixed block 10 and the connecting block 11, the traction rope 13 is fixedly mounted on the fixed block 10 and passes through the spring 12 and the connecting block 11, the guide wheel 14 is arranged on the connecting block 11, the guide wheel 14 and the traction rope 13 are arranged correspondingly, and the driving mechanism is arranged on the support plate 4 to drive the traction rope 13 to reciprocate.

[0023] In this embodiment, the fixed block 10 is firmly mounted on the support plate 4 to provide stable support for the entire traction mechanism. The connecting block 11 is fixedly mounted on the separation frame 5 and slides through the support plate 4, so that the connecting block can reciprocate under the guidance of the fixed block 10. The spring 12, as the main component for generating vibration, is installed between the fixed block 10 and the connecting block 11. When the spring 12 is subjected to external force, it will deform and generate a restoring force, which enables the connecting block 11 to continuously reciprocate on the support plate 4. The traction rope 13 is a key component connecting the driving mechanism and the connecting block. When the driving mechanism drives the traction rope 13 to reciprocate, the connecting block 11 will also reciprocate, thereby driving the separation frame 5 to vibrate. The setting of the guide wheel 14 is to reduce the friction between the traction rope 13 and the connecting block 11 and improve the working efficiency of the entire mechanism. The guide wheel 14 is set corresponding to the traction rope 13, so that the traction rope 13 can slide smoothly on the guide wheel 14 without excessive resistance. The driving mechanism is the power source of the entire traction mechanism. It can adjust the vibration frequency and amplitude as needed, thereby achieving precise control of the walnut shell and kernel separation effect.

[0024] In a further preferred embodiment of the utility model, the driving mechanism includes a rotating motor 15, a disc 16, an eccentric shaft 17 and a limit block 18, the rotating motor 15 is fixedly mounted on the support plate 4, the disc 16 is fixedly mounted on the output shaft of the rotating motor 15, the eccentric shaft 17 is fixedly mounted on the disc 16, the eccentric shaft 17 is fixedly connected to the traction rope 13, the limit block 18 is fixedly mounted on the support plate 4, and the limit block 18 is slidably connected to the traction rope 13.

[0025] In this embodiment, the rotating motor 15 is the power source of the entire driving mechanism, and it is fixedly mounted on the support plate 4. When the motor is started, its output shaft starts to rotate, thereby driving the disc 16 fixedly connected thereto to rotate together. An eccentric shaft 17 is fixedly mounted on the disc 16, which means that the center of the shaft does not coincide with the center of the disc. When the disc rotates, the eccentric shaft will produce a periodic reciprocating motion rather than a simple circular motion. One end of the traction rope 13 is fixedly connected to the eccentric shaft 17, and the other end is connected to the separation frame 5 through the guide wheel 14 and the connecting block 11. When the eccentric shaft 17 reciprocates with the rotation of the disc 16, it pulls the traction rope 13, thereby driving the connecting block 11 and the separation frame 5 to reciprocate on the support plate 4. In order to ensure that the movement trajectory of the traction rope 13 is stable and smooth, a limit block 18 is also provided. The limit block 18 is fixedly mounted on the support plate 4 and is slidably connected to the traction rope 13. When the traction rope 13 moves, it will slide along a predetermined path under the guidance of the limit block without deviating from the direction or generating excessive friction.

[0026] In a further preferred embodiment of the utility model, a detection head 19 is fixedly mounted on the support plate 4 , and the detection head 19 is arranged corresponding to the separation frame 5 . An injection assembly 20 is arranged on the support plate 4 , and the injection assembly 20 is arranged corresponding to the detection head 19 .

[0027] In the present embodiment, the detection head 19 is fixedly mounted on the support plate 4 and is arranged corresponding to the separation frame 5. When the walnut in the separation frame 5 passes through the detection head 19, the sensor will quickly capture the state information of the walnut, identify the walnut kernel and the walnut shell, and control the jet assembly 20 to spray the walnut shell outward. The jet assembly 20 is arranged on the support plate 4 and is arranged corresponding to the detection head 19. The jet assembly 20 includes a plurality of jet nozzles, which can quickly spray airflow when receiving instructions. When the detection head 19 detects that the walnut shell in the separation frame 5 falls, it sends a signal to the jet assembly 20. After receiving the signal, the jet assembly 20 will start immediately, spray appropriate airflow through the jet nozzle, and push the walnut shell away from the original motion trajectory. Since the jet treatment is local and precise, it will not cause damage to the walnut kernel.

[0028] In a further preferred embodiment of the utility model, a discharge device is provided on the separation box 1 for discharging walnut kernels and walnut shells, and the discharge device is arranged corresponding to the jet assembly 20. The discharge device includes a first discharge port 21, two baffles 22, a second discharge port 23 and a guide block 24. The first discharge port 21 is opened on the separation box 1, and the first discharge port 21 is arranged corresponding to the jet assembly 20. The two baffles 22 are respectively fixedly mounted on the separation box 1 and arranged corresponding to the first discharge port 21. The second discharge port 23 is opened at the bottom of the separation box 1 and arranged corresponding to the separation frame 5. The guide block 24 is fixedly mounted on the bottom of the separation box 1 and arranged corresponding to the second discharge port 23.

[0029] In this embodiment, the discharge device is arranged corresponding to the jet assembly 20, ensuring that the walnut shell can quickly and accurately enter the discharge device after being blown away by the jet assembly 20. The first discharge port 21 is opened on the separation box 1 and is arranged corresponding to the jet assembly 20. After the jet assembly 20 blows away the walnut shell, the walnut shell will enter the first discharge port 21 along the air flow direction, thereby achieving preliminary separation from the walnut kernel. Two baffles 22 are respectively fixedly mounted on the separation box 1 and arranged corresponding to the first discharge port 21. The function of the baffle 22 is to prevent the walnut shell from being scattered to other areas during the blowing process, and to ensure that the walnut shell can be discharged through the first discharge port 21 in a concentrated and orderly manner. After the preliminary treatment of the jet assembly 20 and the discharge device, the walnut kernel will fall directly to the bottom. When it reaches the bottom, the walnut kernel will be discharged through the second discharge port 23, achieving complete separation from the walnut shell. The function of the guide block 24 is to guide the walnut kernel to smoothly enter the second discharge port 23 to prevent it from being blocked or scattered during the discharge process.

[0030] In a further preferred embodiment of the utility model, a reciprocating mechanism is provided on the separation box 1 for pushing the guide plate 3 to move up and down along the hinge point, the reciprocating mechanism includes a reciprocating motor 25, a cam 26 and a slide groove 27, the reciprocating motor 25 is fixedly mounted on the separation box 1, the cam 26 is fixedly mounted on the output shaft of the reciprocating motor 25, the cam 26 is in conflict with the guide plate 3, and the slide groove 27 is opened on the inner wall of the separation box 1 and is slidably connected to the guide plate 3.

[0031] In the present embodiment, the reciprocating motor 25 is fixedly mounted on the separation box 1 as a power source to provide a stable power output for the entire reciprocating mechanism. The cam 26 is fixedly mounted on the output shaft of the reciprocating motor 25 and rotates as the motor rotates. When the cam 26 rotates, its outer contour conflicts with the guide plate 3, thereby pushing the guide plate 3 to move up and down along the hinge point. The chute 27 is provided on the inner wall of the separation box 1 and is slidably connected to the guide plate 3. The design of the chute 27 not only provides a stable motion trajectory for the guide plate 3, but also ensures the stability and accuracy of the guide plate 3 during the up and down movement. Through the guiding effect of the chute 27, the guide plate 3 can accurately respond to the push of the cam 26, realize efficient reciprocating motion, prevent walnuts from piling up on the guide plate 3, and deliver the walnuts to the separation frame 5 at the same time.

[0032] In a further preferred embodiment of the utility model, the separation frame 5 is arranged in an inclined shape, and the baffle 22 and the guide block 24 are both arranged in an inclined shape for guiding the walnut shells and walnut kernels.

[0033] In the present embodiment, the interior of the separation frame 5 is designed to be inclined, which can effectively transport walnut kernels and walnut shells, and ensure the unloading of walnut kernels and walnut shells. This design not only improves the separation efficiency, but also reduces the damage of walnuts during the separation process. The baffle 22 and the guide block 24 are also designed to be inclined, mainly used for guiding walnut shells and walnut kernels. The inclined design of the baffle 22 allows the walnut shells to enter the first discharge port 21 more smoothly along the inclined surface after being blown away by the jet assembly 20, preventing the walnut shells from being blocked and scattered during the discharge process. The inclined design of the guide block 24 helps to guide the walnut kernels to enter the second discharge port 23 smoothly, ensuring the smooth discharge of the walnut kernels. This inclined design not only optimizes the separation and discharge process of the walnut shell kernels, but also improves the working efficiency of the entire device.

[0034] In summary, compared with the related art, the shell and kernel separation and screening device for walnut processing of the utility model realizes efficient and accurate separation of walnut shell and kernel as well as orderly discharge as a whole. Through the specially designed separation frame, guide plate, jet assembly and discharge device, the device can make full use of the differences in the physical properties of walnut shell and kernel to achieve effective separation of shell and kernel. At the same time, the design of the reciprocating mechanism makes the separation process more automated and efficient, thereby improving the efficiency of walnut processing. The inclined separation frame, baffle and guide block further optimize the separation and discharge effects, and reduce the damage and waste of walnuts.
