Description

Technical Field

[0001] The invention relates to the technical field of nut shelling, in particular to a macadamia nut shelling device. Background Art

[0002] Macadamia nuts are a type of tree nut native to Australia, also known as macadamia nuts or volcanic beans. They are sweet and delicious, and are rich in nutrients, earning them the title of "Queen of Dried Fruits". The shell of macadamia nuts is round and hard, and must be opened with a special sheller.

[0003] At present, in order to make it easier for people to eat macadamia nuts, most manufacturers will open an arc-shaped slit on one side of the macadamia nut and attach an iron piece of fruit opener to the bag. When eating, hold the shell tightly with one hand and use the iron piece to pry the slit of the macadamia nut with the other hand to split the shell of the macadamia nut and take out the kernel.

[0004] However, this method has many disadvantages. Not only does it require a lot of grip to grasp the shell to prevent the macadamia nut from rotating when the shell is pried, but also in the process of opening, the iron sheet is often inserted too deeply, splitting the kernel together, and the split kernel is located in the shell that is split in half, making it difficult to take out. This results in some female consumers and children with less hand strength being unable to peel and eat them normally. If the macadamia nut is smashed open with a hammer or other tool, it is easy to crush the flesh if the force is not properly controlled, resulting in a waste of flesh and a certain risk. In addition, the tool needs to be used with both hands, which greatly increases the complexity of the operation.

[0005] Therefore, in view of the above problems, developing a new macadamia nut shelling device is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1-3 As shown, the present invention provides a macadamia nut shelling device, comprising a fixed cylinder 1 and a driving handle, one end of the driving handle being hinged to the fixed cylinder 1; wherein a guide groove 2 is provided on the side of the fixed cylinder 1, a shelling assembly is slidably arranged in the guide groove 2, and the driving handle is used to drive the shelling assembly to slide along the guide groove 2 to realize macadamia nut shelling.

[0032] The macadamia nut shelling device of the present invention comprises a fixed cylinder 1 and a driving handle. When in use, the macadamia nut only needs to be placed in the fixed cylinder 1, and the shelling component is embedded in the crack of the macadamia nut. By holding the driving handle with one hand, the shelling component can be driven to move relatively, thereby opening the macadamia nut. The device is simple to operate and easy to use, suitable for most people, and effectively solves the problem that the iron sheet shelling device is time-consuming and labor-intensive, and easily causes the nut kernel to break.

[0033] In a specific embodiment of the present invention, the driving handle specifically includes a handle body 3 and a driving rod 4 fixed on the handle body 3, one end of the handle body 3 is hinged to the fixed cylinder 1, and the driving rod 4 is used to drive the shell opening component to slide along the guide groove 2 to realize the shell opening of macadamia nuts. When it is necessary to open the shell of macadamia nuts, align the crack of macadamia nuts with the shell opening component and put it into the fixed cylinder 1, hold the fixed cylinder 1 and the handle body 3 with one hand, and then squeeze the fixed cylinder 1 and the handle body 3 hard, so as to drive the driving rod 4 to move toward the fixed cylinder 1, and then drive the shell opening component to slide along the guide groove 2. At this time, because the shell opening component is located in the crack of macadamia nuts, the shell opening component is driven by the driving rod 4 to move relatively, thereby forcing the macadamia nuts to open the shell.

[0034] In order to facilitate the automatic reset of the handle body 3 and the driving rod 4, an elastic component 5 is provided between the handle body 3 and the fixed cylinder 1. The present invention does not limit the specific form of the elastic component 5, which can be a spring or other elastic body that can cause the handle body 3 to reset.

[0035] In addition, the connection position between the fixed cylinder and the handle body 3 is not specifically limited, and can be installed at the top, upper middle part or middle part of the fixed cylinder. In a specific embodiment of the present invention, the handle body 3 is hingedly arranged on the top of the fixed cylinder 1. Specifically, a groove is provided on the top of the fixed cylinder 1, and a through hole is provided on both sides of the inner part of the groove. The handle body 3 passes through the handle body 3 through a pin shaft 6, and the through hole is hinged to the fixed cylinder 1.

[0036] On the basis of the above technical solution, the shell opening assembly specifically includes a left shell opening block and a right shell opening block, the left shell opening block and the right shell opening block are relatively slidably arranged in the guide groove 2, and the driving rod 4 is used to drive the left shell opening block and the right shell opening block to slide along the guide groove 2 to realize the shell opening of macadamia nuts. That is, when in use, the left shell opening block and the right shell opening block are both embedded in the crack of macadamia nuts, and the driving rod 4, under the action of the handle body 3, drives the left shell opening block and the right shell opening block to slide along the guide groove 2 to realize the shell opening of macadamia nuts, and the left shell opening block and the right shell opening block will not extend into the inside of the fruit shell to damage the flesh, thereby ensuring the integrity of the flesh.

[0037] like Figure 4 As shown, on the basis of the above technical solution, it is further preferred that the left shell opening block and the right shell opening block respectively include a guide column 7 and a shell opening piece 8, the guide column 7 is slidably connected to the guide groove 2, and the driving rod 4 is used to drive the guide column 7 to drive the shell opening piece 8 to move so as to realize the shell opening of macadamia nuts. The guide column 7 and the shell opening piece 8 here can be selected in an integrated processing and molding manner, and when the guide column 7 slides in the guide groove 2, it drives the shell opening piece 8 to move relatively, thereby forcing the macadamia nuts to be shelled.

[0038] In another specific embodiment of the present invention, in order to facilitate the timely resetting of the shell opening piece 8 for the next macadamia nut shell opening, an elastic component 5 is provided between the shell opening piece 8 and the inner side wall of the fixed cylinder 1. When the two shell opening pieces 8 are separated under the action of the driving rod 4, the elastic component 5 between the shell opening piece 8 and the inner side wall of the fixed cylinder 1 will be compressed. After the shell opening is completed, the elastic component 5 rebounds, thereby causing the shell opening piece 8 to quickly and automatically reset. Similarly, the present invention does not limit the specific form of the elastic component 5, which can be a spring or other elastic body that can cause the shell opening piece 8 to reset.

[0039] On the basis of the above scheme, more preferably, the inner diameter of the fixing cylinder 1 matches the outer diameter of the macadamia nuts to ensure the fixation of the macadamia nuts.

[0040] The sum of the thicknesses of the two shell-opening pieces 8 is less than or equal to the gap of the macadamia nut to ensure that the two shell-opening pieces 8 can be completely embedded in the gap of the macadamia nut.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
