Description

Technical Field

[0001] This utility model relates to the field of nut processing, and in particular to a nut shelling device. Background Technology

[0002] Nuts are a type of food with a hard shell and edible seeds inside, such as chestnuts, almonds, and walnuts. They are rich in nutrients and have excellent effects on human growth, development, and physical fitness. Before eating the nuts, the shells need to be broken to remove the edible parts inside.

[0003] Chinese patent announcement number CN221430180U discloses a nut shelling device, relating to the field of shelling devices. This nut shelling device includes a shelling equipment housing, inside which a crushing roller is installed. A transmission gear is mounted on the shaft of the crushing roller, and two sets of transmission gears mesh. A protective shell is installed on the outer side of the shelling equipment housing, and a grease storage tank is movably engaged on the protective shell. A lubrication wheel is rotatably connected inside the grease storage tank, and the lubrication wheel is in contact with the top of the transmission gears. A pressure block is slidably connected inside the grease storage tank. When the crushing roller is driven by a motor, the transmission gears driving the two sets of crushing rollers in this nut shelling device can be automatically lubricated, reducing the resistance and wear of the transmission gears, extending their service life, and ensuring smooth transmission. Furthermore, it eliminates the need for manual lubrication, making the lubrication process convenient and ensuring the stable operation of the nut shelling device, meeting usage requirements.

[0004] However, this device has the following drawbacks: although it can shell nuts using two crushing rollers, the fixed spacing between the rollers and the varying sizes of the nuts cause smaller nuts to easily slip between them, making it impossible to shell them. To address these drawbacks, we propose a nut shelling device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nut-opening device.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a nut shelling device, comprising:

[0007] The housing includes a cylindrical body, a support leg fixedly installed on the surface of the cylindrical body, a feeding frame fixedly installed on the upper surface of the cylindrical body, and a discharge trough opened in the bottom wall of the inner body of the cylindrical body.

[0008] The shell-breaking structure is located inside the cylinder and is used to open the shells of nuts. It includes a first connecting shaft and a second connecting shaft that are rotatably mounted on each other, a spiral blade that is fixedly mounted on the surface of the first connecting shaft, and a first rubber roller and a second rubber roller that are fixedly mounted on the surface of the second connecting shaft. The second rubber roller is shaped as a cone that is wider on the left and narrower on the right.

[0009] A feeding structure is provided inside the feeding frame for feeding the shell-breaking structure.

[0010] The first driving structure is located on the left side of the cylinder and is used to drive the shell-breaking structure to rotate. It includes a first spur gear and a second spur gear that are rotatably mounted on the left side of the cylinder, and a motor that is fixedly mounted on the left side of the first spur gear. The first spur gear and the second spur gear are fixedly connected to the left ends of the first connecting shaft and the second connecting shaft, respectively.

[0011] The second drive structure is located on the left side of the feeding frame and is used to drive the feeding structure to rotate.

[0012] Preferably, the first spur gear meshes with the second spur gear for transmission.

[0013] Preferably, the feeding structure includes a feeding roller rotatably mounted on the inner wall of the feeding frame, and storage holes equidistantly opened on the surface of the feeding roller.

[0014] Preferably, the second drive structure includes a driven pulley rotatably mounted on the left side of the feeding frame and a drive pulley fixedly mounted on the left end of the second spur gear, and the right end of the driven pulley is fixedly connected to the left end of the feeding roller.

[0015] Preferably, the drive pulley and the driven pulley are connected by a belt drive.

[0016] Preferably, two guide plates are fixedly installed on the inner wall of the cylinder.

[0017] Preferably, a material discharge plate is fixedly installed on the lower surface of the cylinder, and the material discharge plate is located directly below the discharge chute.

[0018] Preferably, the first rubber roller is located to the left of the second rubber roller, and the first rubber roller is located below the feeding frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting up a shell-breaking structure and a first driving structure, when the nuts fall into the cylinder from the feeding structure, the nuts are located between the spiral blades and the first rubber roller. As the spiral blades rotate, the nuts are driven to be conveyed along the first rubber roller to the second rubber roller. The extrusion force generated between the spiral blades and the second rubber roller can be used to break the shells of the nuts. Since the shape of the second rubber roller is set as a cone that is wider on the left and narrower on the right, the distance between the second rubber roller and the spiral blades will gradually increase from left to right. Larger nuts that cannot be shelled will continue to be conveyed to the right, while smaller nuts will be shelled. This process continues until the larger nuts are conveyed to the appropriate position, at which point the larger nuts can be shelled. This allows for the shelling of nuts of different sizes, avoiding the defect of smaller nuts being missed.

[0021] 2. By setting up a feeding structure, when the nuts are put into the feeding frame, the second drive structure can drive the feeding roller to rotate. At this time, the nuts in the feeding frame will fall into the storage hole one by one. As the feeding roller rotates, the nuts in the storage hole can fall into the cylinder, so that the nuts in the feeding frame can be fed evenly, avoiding too many nuts entering the cylinder and affecting the shelling quality.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a nut shelling device, comprising: a shell, a shell-breaking structure, a feeding structure, a first driving structure, and a second driving structure.

[0030] See Figure 1-2 The shell includes a cylinder 10, a support leg 11 fixedly installed on the surface of the cylinder 10, a feeding frame 12 fixedly installed on the upper surface of the cylinder 10, and a discharge trough 13 opened in the inner bottom wall of the cylinder 10. A discharge plate 70 is fixedly installed on the lower surface of the cylinder 10, and the discharge plate 70 is located directly below the discharge trough 13. When the nuts are discharged from the discharge trough 13, the discharge plate 70 will buffer and guide the nuts.

[0031] See Figure 2 and Figure 3 The shell-breaking structure is located inside the cylinder 10 and is used to open the shells of nuts. It includes a first connecting shaft 20 and a second connecting shaft 21 that are rotatably mounted on each other, a spiral blade 22 that is fixedly mounted on the surface of the first connecting shaft 20, and a first rubber roller 23 and a second rubber roller 24 that are fixedly mounted on the surface of the second connecting shaft 21. The second rubber roller 24 is shaped as a cone that is wider on the left and narrower on the right.

[0032] See Figure 1 and Figure 3 The first driving structure is located on the left side of the cylinder 10 and is used to drive the shell-breaking structure to rotate. It includes a first spur gear 30 and a second spur gear 31 that are rotatably mounted on the left side of the cylinder 10, and a motor 32 that is fixedly mounted on the left side of the first spur gear 30. The first spur gear 30 and the second spur gear 31 are fixedly connected to the left ends of the first connecting shaft 20 and the second connecting shaft 21, respectively. The first spur gear 30 and the second spur gear 31 mesh and drive each other. The drive motor 32 can drive the first spur gear 30 to rotate. By using the meshing transmission of the first spur gear 30 and the second spur gear 31, the first connecting shaft 20 and the second connecting shaft 21 can be driven to rotate.

[0033] See Figure 2-3 Two guide plates 60 are fixedly installed on the inner wall of the cylinder 10. The first rubber roller 23 is located to the left of the second rubber roller 24 and is located below the feeding frame 12.

[0034] When the nuts fall from the feeding frame 12 into the cylinder 10, they are positioned between the spiral blade 22 and the first rubber roller 23. As the spiral blade 22 rotates, it drives the nuts to be conveyed along the first rubber roller 23 to the second rubber roller 24. The extrusion force generated between the spiral blade 22 and the second rubber roller 24 can be used to crack the nuts. Since the second rubber roller 24 is shaped like a cone with a wider left side and a narrower right side, the distance between the second rubber roller 24 and the spiral blade 22 gradually increases from left to right. Larger nuts that cannot be cracked will continue to be conveyed to the right, while smaller nuts will be cracked. Once the larger nuts are conveyed to the appropriate position, they can be cracked. This process allows for the cracking of nuts of different sizes, avoiding the defect of smaller nuts being missed.

[0035] See Figure 1 , Figure 2 and Figure 4 The feeding structure is located inside the feeding frame 12 and is used to feed the shell-breaking structure. The feeding structure includes a feeding roller 40 that is rotatably installed on the inner wall of the feeding frame 12, and storage holes 41 that are equidistantly opened on the surface of the feeding roller 40.

[0036] The second drive structure is located on the left side of the feeding frame 12 and is used to drive the feeding structure to rotate. The second drive structure includes a driven pulley 50 rotatably mounted on the left side of the feeding frame 12 and a drive pulley 51 fixedly mounted on the left end of the second spur gear 31. The right end of the driven pulley 50 is fixedly connected to the left end of the feeding roller 40. The drive pulley 51 and the driven pulley 50 are connected by belt drive. When the second spur gear 31 rotates, it can drive the drive pulley 51 to rotate. The belt drive can drive the driven pulley 50 to rotate, thereby driving the feeding roller 40 to rotate.

[0037] When the nuts are placed in the feeding frame 12, the second drive structure can drive the feeding roller 40 to rotate. At this time, the nuts in the feeding frame 12 will fall into the storage hole 41 one by one. As the feeding roller 40 rotates, the nuts in the storage hole 41 can fall into the cylinder 10, so that the nuts in the feeding frame 12 can be fed evenly, avoiding too many nuts entering the cylinder 10 and affecting the shelling quality.

[0038] Working principle:

[0039] Pour the nuts into the feeding basket;

[0040] The drive motor 32 can drive the first spur gear 30 to rotate. The meshing transmission of the first spur gear 30 and the second spur gear 31 can drive the drive pulley 51 to rotate. The transmission of the belt can drive the driven pulley 50 to rotate, which in turn can drive the feeding roller 40 to rotate. At this time, the nuts in the feeding frame 12 will fall into the storage hole 41 one by one. As the feeding roller 40 rotates, the nuts in the storage hole 41 can fall into the cylinder 10, so that the nuts in the feeding frame 12 can be fed evenly.

[0041] When the first spur gear 30 and the second spur gear 31 mesh and drive each other, the first connecting shaft 20 and the second connecting shaft 21 can be driven to rotate, which in turn can drive the first rubber roller 23, the second rubber roller 24 and the spiral blade 22 to rotate.

[0042] When the nuts fall into the cylinder 10, they are positioned between the spiral blades 22 and the first rubber roller 23. As the spiral blades 22 rotate, they drive the nuts along the first rubber roller 23 to the second rubber roller 24. The pressure generated between the spiral blades 22 and the second rubber roller 24 can then be used to crack the nuts. Since the second rubber roller 24 is a conical shape that is wider on the left and narrower on the right, the distance between the second rubber roller 24 and the spiral blades 22 gradually increases from left to right. Larger nuts that cannot be cracked will continue to be conveyed to the right, while smaller nuts will be cracked. This process continues until the larger nuts are conveyed to the appropriate position, at which point they can be cracked. This allows for the cracking of nuts of different sizes.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
