Description
Technical Field
[0001] The invention relates to the technical field of nut processing equipment, and in particular to a nut screening and shelling equipment. Background Art
[0002] With the development of the market economy, in response to the ever-increasing consumer demand, nuts can be shelled during the production process. After shelling, consumers can eat the kernels directly without additional processing. Shelled nuts are easier to carry and eat, suitable for fast-paced life. In addition, many foods, such as nut butters, candies, and baked products, require nuts as raw materials, which require nuts to be shelled before use.
[0003] Take walnuts as an example. During the shelling process, most of the walnut shells are crushed by pressure to facilitate direct consumption. However, after the shelling of walnuts and other nuts is completed, a large number of shelled nuts are still mixed with a certain amount of broken shells. In order to ensure the quality of the nuts, the broken shells inside need to be removed.
[0004] The existing method of removing broken shells mostly uses a filter structure to separate small-volume broken shells. However, in the process of removing broken shells from a large number of shelled nuts, the nuts are easily accumulated on the surface of the filter, causing the falling speed of the broken shells to slow down, affecting the efficiency of the nut shelling operation, and easily leading to incomplete cleaning of the broken shells. Therefore, the present application provides a nut screening and shelling device to meet the needs. Summary of the invention

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0034] Example 1: Reference Figure 1-4 The nut screening and shelling equipment shown comprises an enclosure frame 1 and a rotatable placing frame 2, wherein the placing frame 2 is located inside the enclosure frame 1, a screening net 3 which can move laterally is provided below the enclosure frame 1, and a collecting frame is provided below the screening net 3.
[0035] Specifically, during the operation of the nut screening and shelling equipment, the nuts to be shelled are placed in the placing rack 2, and a pressure shelling unit is provided above the placing rack 2. After being shelled by the pressure shelling unit, the nuts in the placing rack 2 can fall onto the surface of the screening net 3 in a lateral movement state as the placing rack 2 rotates, and the broken shells in the nuts fall into the collecting rack through the sieve holes of the screening net 3. Through this operation, the broken shells in the nuts after shelling can be effectively removed to achieve the purpose of sufficient impurity removal, reduce the time required in the manual sorting and impurity removal process, and improve the efficiency of nut processing operations.
[0036] When a large number of cracked nuts fall onto the screening net 3, they tend to accumulate on the screening net 3, which slows down the falling speed of the broken shells in the nuts. In order to increase the falling speed of the broken shells in the nuts, a screening net 3 that can move laterally is provided. When the screening net 3 is in a transverse state, the nuts accumulated on its surface can be quickly transferred, which effectively reduces the accumulation of nuts and makes the nuts flat on the screening net 3, thereby increasing the falling speed of the broken shells in the nuts and further increasing the screening speed.
[0037] A frame 4 is provided below the enclosure frame 1, and a guide frame 5 is provided on the frame 4 which can jump synchronously with the lateral movement of the screening net 3. The guide frame 5 is located below the screening net 3, and a plurality of arranged and distributed pressure columns 6 are provided on the side of the guide frame 5 facing the screening net 3. With the jumping of the guide frame 5, the plurality of pressure columns 6 synchronously hit the screening net 3, and the pressure columns 6 have a shaking effect on the screening net 3. The shaking force can effectively prevent the screening net 3 from being blocked, and can quickly separate the nuts from the broken shells. While ensuring the smoothness of the surface of the screening net 3, the broken shells in the nuts can also fall comprehensively and quickly, further improving the efficiency of nut removal.
[0038] Specifically, Figure 3-6 As shown, both sides of the screening net 3 are provided with moving blocks 31 extending to the outside of the frame 4, the end of the moving block 31 exposed to the outside of the frame 4 is provided with a slide groove connecting rod 32, the side of the slide groove connecting rod 32 away from the frame 4 is provided with a guide wheel 7, and the eccentric position of the guide wheel 7 is provided with a guide column 71 extending to the inside of the slide groove connecting rod 32.
[0039] The frame 4 is provided with two transverse guide rails 33 which can respectively accommodate the sliding of the moving block 31. With the rotation of the guide wheel 7, the guide column 71 is located inside the slide groove connecting rod 32 and rotates. Under the rotation pressure of the guide column 71, the slide groove connecting rod 32 can be forced to move back and forth transversely, so as to achieve the purpose of pulling the moving block 31 inside the transverse guide rail 33 to do a reciprocating transverse movement, and the screening net 3 can move synchronously transversely.
[0040] In order to provide driving force for the two guide wheels 7, the guide wheels 7 are connected to the synchronous wheels 10 through the synchronous belt 9, and the synchronous wheels 10 located on both sides of the frame 4 are connected through the same rotating shaft, which is arranged on the frame 4, and one end of the rotating shaft is provided with a motor 1 that can control its rotation, and the guide wheels 7, the synchronous wheels 10 and the motor 1 are all installed on the outside of the frame 4 through a bracket. When the motor 1 is running, under the connection of the synchronous belt 9, the guide wheels 7 and the synchronous wheels 10 can be rotated synchronously, so as to achieve the purpose of driving the screening net 3 to move horizontally.
[0041] like Figure 5 , Figure 6 As shown, the frame 4 is provided with a channel for accommodating the guide frame 5 to be exposed, and the two ends of the guide frame 5 located outside the frame 4 are provided with pressure wheels 51, and the parts of the guide frame 5 exposed to the outside of the frame 4 are connected to the frame 4 through an elastic structure, and the side of the guide wheel 7 away from the frame 4 is provided with a driving cam 8 that can rotate synchronously with it, and the driving cam 8 is located directly above the pressure wheel 51. In a natural state, the pressure column 6 is closely attached to the lower surface of the screening net 3. With the rotation of the guide wheel 7, the driving cam 8 rotates to press the pressure wheel 51 to descend until the elastic structure contracts, the pressure wheel 51 and the guide frame 5 descend, and the pressure column is separated from the screening net 3.
[0042] With the continuous rotation of the guide wheel 7, the driving cam 8 is separated from the pressure wheel 51, and the elastic structure can carry the guide frame 5 to reset, so that the pressure wheel 51, the guide frame 5 and the pressure column 6 can bounce back elastically. With the continuous transverse movement of the screening net 3, the guide frame 5 and the pressure column 6 can bounce continuously. In this process, the screening net 3 can be continuously collided to generate an oscillating force. Under the oscillating force, the clogging of the screening net 3 can be effectively avoided, and the nuts and the broken shells can be quickly separated. While ensuring the patency of the surface of the screening net 3, the broken shells in the nuts can also be comprehensively and quickly reduced.
[0043] The elastic structure includes a pressure spring 52 arranged at the bottom end of the guide frame 5. The bottom end of the pressure spring 52 is arranged on the frame 4 through a positioning joint 53. Both sides of the frame 4 are provided with a vertical rod 54 that penetrates the guide frame 5. The positioning joint 53 and the pressure spring 52 are located outside the vertical rod 54. When the driving cam 8 rotates to press the pressure wheel 51 to descend, the pressure spring 52 shrinks along the distribution direction of the vertical rod 54. When the driving cam 8 is separated from the pressure wheel 51, the pressure spring 52 is reset along the distribution direction of the vertical rod 54 to achieve the purpose of driving the guide frame 5 to jump. The setting of the vertical rod 54 can maintain the stability of the jumping path of the guide frame 5 and the pressure column 6, and avoid the deviation of the guide frame 5 and the pressure column 6 during the jumping process.
[0044] Example 2: Figure 7-10As shown, on the basis of Example 1, a plurality of shell breaking channels 21 recessed downward are provided on the placing rack 2, and a driving shaft 22 and a supporting shaft 23 are provided on both sides of the placing rack 2, the driving shaft 22 is installed on the side wall of the enclosure frame 1, and a motor 2 for controlling the rotation of the driving shaft 22 is provided on the outside of the enclosure frame 1, and a supporting guide rail 15 for accommodating the supporting shaft 23 is provided on the inside of the enclosure frame 1. During the operation of the nut screening and shell breaking equipment, the motor 2 drives the placing rack 2 to rotate around the driving shaft 22 as the center, and the supporting shaft 23 is located in the supporting guide rail 15 and rotates, so that the shell breaking channels 21 are tilted and receive the falling nuts to be shelled. Under the action of gravity, the falling nuts can be distributed along the path of the shell breaking channels 21.
[0045] When the shelling operation is completed, the placing rack 2 can be rotated around the driving shaft 22 again under the action of the second motor, and the inclination angle increases, so that the nuts located inside the shelling channel 21 fall smoothly onto the surface of the screening net 3.
[0046] It is worth noting that a protective block 16 is provided inside the placing rack 2 and the surrounding rack 1, and the protective block 16 is opposite to one end of the shell breaking channel 21 close to the support shaft 23. The protective block 16 has a blocking effect on the nuts, and can prevent the nuts in the shell breaking channel 21 from falling. When the placing rack 2 rotates around the driving shaft 22 again, and the inclination angle increases, the protective block 16 and the placing rack 2 are staggered, and the blocking of the shell breaking channel 21 is released, so that the nuts can fall smoothly.
[0047] Specifically, the pressure shell breaking unit includes a plurality of extrusion bars 11 directly above the shell breaking channel 21, and the plurality of extrusion bars 11 are connected by a movable frame 12 that can be raised and lowered, and a support frame 13 is provided on the enclosure frame 1, and a pneumatic component 14 that can control the lifting and lowering movement of the movable frame 12 is provided on the support frame 13. When the nuts to be shelled fall into the shell breaking channel 21, the movable frame 12 and the extrusion bars 11 are lowered under the driving force of the pneumatic component 14, and the extrusion bars 11 can squeeze the nut shell to break it.
[0048] In order to allow the nut raw materials to fall smoothly into the shelling channel 21, an inclined discharge rack 17 is provided above the enclosure frame 1. The discharge rack 17 is connected to the frame 4, and a plurality of conveying pipes 18 for accommodating the falling nuts are provided at the lower position of the discharge rack 17. The bottom ends of the conveying pipes 18 extend to the inner sides of the shelling channel 21 respectively.
[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
