[0002] Macadamia nuts, also known as macadamia nuts, Australian walnuts or Australian walnuts, are a tree nut native to Australia. Macadamia nuts not only taste great, but are also rich in nutritional value. It is rich in unsaturated fatty acids, which can regulate blood sugar and improve the metabolic level of diabetic patients. It is also beneficial to cardiovascular and cerebrovascular health and can prevent the occurrence of certain cardiovascular and cerebrovascular diseases. In addition, macadamia nuts also contain a large amount of vitamin E, which is a powerful antioxidant that can remove free radicals in the body, delay skin aging, and prevent rheumatic diseases. The chlorophyll in macadamia nuts can promote metabolism and help cells heal. In addition, it also contains a variety of essential amino acids for the human body, which can play a role in nourishing the brain.

[0003] Macadamia nuts are shaped like olives, and ripe fruits have a layered structure. The first layer is the green skin layer, which is thicker and the kernel is wrapped in a harder shell.

[0026] The utility model provides a macadamia nut green skin shelling machine 100.

[0027] See also Figure 1-Figure 3 In one embodiment of the utility model, the macadamia nut green skin shelling machine 100 includes a frame 30, a shelling bin 10 and a vibrating screening structure 20. The shelling bin 10 is arranged on the frame 30 and is provided with a scraper 40 inside, which is used to shell the macadamia nuts for green skin. The shelling bin 10 is provided with a feed port 11 at the upper end and a discharge port 12 at the lower end. The vibrating screening structure 20 includes a screening element 21 and a pulling element 22. The starting end of the screening element 21 is located below the discharge port 12. The screening element 21 is inclined downward from the discharge port 12 and is provided with a number of notches 21a, which are used to screen the external green skin of macadamia nuts. A rotating element 23 is provided on the shelling bin 10, and one end of the pulling element 22 is connected to the screening element 21, and the other end is connected to the rotating element 23.

[0028] In this embodiment, a driving member 43 is provided outside the shelling bin 10, and the scraper 40 includes a tool roller 42 and a rotating roller 41, wherein the tool roller 42 is sleeved outside the rotating roller 41, and the driving member 43 is connected to the rotating roller 41, and one side of the rotating roller 41 is exposed outside the shelling bin 10, and the rotating member 43 is installed on the exposed part of the rotating roller 41, wherein the driving member 43 can be a common stepping motor, but is not limited to this, after connecting to an external power supply, the driving member 43 can drive the scraper 40 to rotate in the shelling bin 10 to shell the nuts, and at the same time, the rotating roller 41 drives the rotating member 23 to rotate together while rotating.

[0029] In one embodiment of the utility model, the rotating member 23 is provided with a connecting column 231, and the connecting column 231 is eccentrically arranged. The screening member 21 is provided with a convex strip 211. One end of the pulling member 22 is connected to the connecting column 231, and the other end is connected to the convex strip 211. The frame 30 is provided with a first support frame 31 and a second support frame 32. One end of the screening member 21 is mounted on the first support frame 31, and the other end is mounted on the second support frame 32. The first support frame 31 is provided with a first sliding groove 31a, and the second support frame 32 is provided with a second sliding groove 32a. The two ends of the screening member 21 are respectively mounted in the first sliding groove 31a and the second sliding groove 32a.

[0030] In this embodiment, a first sliding column 311 is provided in the first sliding groove 31a, and a second sliding column 321 is provided in the second sliding groove 32a. The first sliding column 311 is sleeved with a first elastic member 33, and the second sliding column 321 is sleeved with a second elastic member 34. The first elastic member 33 and the second elastic member 34 respectively abut against the screening element 21, so that the screening element 21 can only abut against the bottom of the first sliding groove 31a and the second sliding groove 32a in a normal state; wherein, limit platforms 212 are provided at both ends of the screening element 21, and through holes 213 are provided on the limit platforms 212 at both ends, and the through holes 213 on both sides cooperate with the first sliding column 311 and the second sliding column 321, so that the screening element 21 can only move along the first sliding column 311 and the second sliding column 321, and cannot occur lateral movement, thereby improving stability.

[0031] The pulling member 22 can be a nylon rope, and the first elastic member 33 and the second elastic member 34 can both be springs, but are not limited to this; it can be understood that the rotating member 23 is in a standard annular shape, and the position of the connecting column 231 is eccentric. When the rotating member 23 rotates, the connecting column 231 continuously changes its position, and the length of the pulling member 22 is fixed. When the connecting column 231 moves to a position relatively far away from the screening member 21, the screening member 21 is pulled to move upward. In the process of the connecting column 231 rotating to a position relatively close to the screening member 21, under the elastic force of the first elastic member 33 and the second elastic member 34, the screening member 21 rebounds to the initial position. During the whole movement, the screening member 21 reciprocates up and down to generate vibration; after the nuts are peeled in the shelling bin 10, they fall from the discharge port onto the screening member 21, and the screening member 21 generates vibration to screen the peels and kernels.

[0032] In one embodiment of the utility model, the width of each notch 21a gradually increases from the starting end to the end of the screening element 21, and a collecting basket 50 is provided on the frame 30. The collecting basket 50 is located below the screening element 21. A partition plate 51 is provided in the collecting basket 50 to separate the internal space of the collecting basket 50.

[0033] It can be understood that after the macadamia nuts are shelled without green skin in the shelling bin 10, the green skin and kernels fall onto the screening element 21 from the discharge port 12. The screening element 21 moves repeatedly to generate vibrations, thereby accelerating the green skin to fall from the notch 21a. The width of the notch 21a becomes larger as it tilts downward. Because the green skin is generally smaller, it falls at the starting end of the notch 21a when it falls, and the macadamia nuts continue to slide down along the screening element 21. When the width of the notch 21a is greater than the outer diameter of the macadamia nuts, the macadamia nuts fall from the corresponding notch 21a to the collection basket 50, so that macadamia nuts of different sizes can be screened.

[0034] Working principle: macadamia nuts are put into the shelling bin 10 from the feed port 11 for shelling of the green skin. After shelling of the green skin is completed, the green skin and macadamia nuts fall from the discharge port 12 to the screening element 21. With the cooperation of the rotating member 23 and the pulling member 22, the screening element 21 reciprocates to generate vibration, thereby accelerating the screening of the green skin and kernels. The green skin falls from the initial end of the notch 21a, and the macadamia nuts continue to slide down along the screening element 21. When the width of the notch 21a is greater than the outer diameter of the macadamia nuts, the macadamia nuts fall from the corresponding notch 21a to the collecting basket 50, so that macadamia nuts of different sizes can be screened.

[0035] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
