Description

Technical Field

[0001] This utility model specifically relates to the field of nut peeling technology, and more specifically to a macadamia nut peeling machine. Background Technology

[0002] Macadamia nuts are actually the common name for Australian nuts. The fruit is a drupe, green when immature, and turns brown when ripe. The kernel inside is wrapped in a brown seed coat and has a high oil content. Macadamia nuts need to be peeled after harvesting. Peeling macadamia nuts usually refers to removing the outer fleshy skin of the fruit, leaving the hard nut shell. Because the outer skin of macadamia nuts has a high water content, if it is not peeled in time after harvesting, it is easy for mold to grow and rot in a high temperature and humidity environment. Therefore, macadamia nuts need to be peeled in time after harvesting.

[0003] Currently, most macadamia nut peeling machines use roller or rolling machines, which separate the peel from the nut shell through the friction of rotating rollers or the squeezing action of rolling rollers.

[0004] However, in practice, it has been noted that the inner wall of the drum-type peeling machine has ridges. When the fresh fruit rotates with the drum, the ridges rub against the peel, causing it to break and fall off. When peeling in large quantities, some fresh fruit cannot rub against the ridges, resulting in some fresh fruit not being peeled completely. Moreover, there are cases where some peel still sticks to the outside of the nut shell after colliding with the ridges. This requires manual processing of some nuts that are not completely peeled, resulting in poor peeling quality. Utility Model Content

[0005] The purpose of this invention is to provide a macadamia nut peeling machine. The machine uses a nut positioning seat on a nut conveying mechanism to position the macadamia nuts. The nut positioning seat is also equipped with a cross-shaped opening blade corresponding to a straight opening blade. The extrusion between the straight and cross-shaped opening blades divides the outer skin of the nut, improving the peeling effect. This solves the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A macadamia nut peeling machine includes a mounting frame, a shell conveying mechanism movably connected to the inner side of the mounting frame, and side supports and knocking openers arranged in a rectangular array above the shell conveying mechanism, with the knocking openers arranged in a rectangular array and movably connected to the side supports.

[0008] The percussion mouth opener includes a vibrating percussion rod, with a metal percussion head and a rotating sleeve integrally formed at both ends of the vibrating percussion rod, and a slotted knife is fixedly connected to the bottom of the metal percussion head.

[0009] As a further technical solution of this utility model, the side support includes symmetrically arranged support plates, a support crossbar is fixedly connected between the two support plates, and a rotating sleeve is sleeved on the outside of the support crossbar in a rectangular array.

[0010] As a further technical solution of this utility model, a spring hanging rod is also provided above the supporting crossbar, and both ends of the spring hanging rod are fixedly connected to the supporting upright plate.

[0011] One end of the tension spring is engaged with the spring rod, and the other end is engaged with the perforated lug integrally provided at the end of the rotating sleeve.

[0012] As a further technical solution of this utility model, a rotating shaft is movably connected between the symmetrically described support plates, and a transmission pulley is fixedly connected through the rotating shaft through the support plate. Moreover, a linkage belt is sleeved on the outer side of the transmission pulley.

[0013] The rotating shaft is fixedly connected in a rectangular array with cylindrical cams corresponding to the vibrating striking rod, and the cylindrical cams are located below the vibrating striking rod.

[0014] As a further technical solution of this utility model, the shell fruit conveying mechanism includes shell fruit positioning seats arranged in a ring array, and each shell fruit positioning seat is provided with a positioning groove corresponding to the metal striking head, and the inner side of the positioning groove is provided with a cross-shaped opening knife that is fixedly connected to the shell fruit positioning seat.

[0015] As a further technical solution of this utility model, both ends of the shell fruit positioning seat are provided with driving rollers, both ends of the driving rollers are integrally provided with support shafts, and each side of the support shaft is provided with a sliding bearing seat that is fixedly connected to the mounting frame through an interference fit, and one end of the support shaft is also fixedly connected with a driving disc.

[0016] As a further technical solution of this utility model, the drive disc includes a driven gear and a large pulley arranged coaxially, and the driven gear and the large pulley are fixedly connected. In this case, any one of the rotating shaft ends is fixedly connected to a driving pulley corresponding to the large pulley, and a transmission belt is used for transmission between the driving pulley and the large pulley.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, a tension spring applies kinetic energy to a vibrating striking rod. When the metal striking head at the end of the vibrating striking rod falls, it strikes the outer shell. The vibration generated during the striking causes the peel to separate from the nut shell. Furthermore, the slotted blade at the bottom of the metal striking head can cut the peel, causing it to crack and making it easier to peel off, thereby improving the peeling effect.

[0019] 2. In this utility model, the rectangular array of positioning grooves on the shell positioning seat can position the shelled fruit and prevent it from rolling when it is tapped. In addition, the cross-shaped opening blade on the inner side of the positioning groove, together with the tapping of the metal tapping head, divides the peel at the bottom, reduces the area of ​​the peel, thereby reducing the contact area between the peel and the nut shell, making it easier for the peel to fall off the nut shell quickly, and further improving the peeling effect on macadamia nuts.

[0020] 3. In this utility model, through the transmission cooperation between the driven gear and the driving gear, the drive motor drives the shell fruit conveying mechanism to rotate through the driven gear, and the driven gear and the large pulley rotate synchronously. Then, through the transmission cooperation between the driven gear and the drive pulley, the rotating shaft rotates. The cylindrical cam on the rotating shaft, corresponding to the vibrating striking rod, can make the end of the vibrating striking rod swing up and down continuously, continuously striking the shell fruit.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-9 This utility model provides a macadamia nut peeling machine, including a mounting frame 2, a shell conveying mechanism 4 movably connected to the inner side of the mounting frame 2, and a side support 5 and a knocking opener 6 arranged in a rectangular array above the shell conveying mechanism 4, and the knocking opener 6 is movably connected to the side support 5 in a rectangular array.

[0034] The percussion opening device 6 includes a vibrating percussion rod 61. The two ends of the vibrating percussion rod 61 are respectively provided with a metal percussion head 62 and a rotating sleeve 65. The bottom of the metal percussion head 62 is fixedly connected to a slotted opening knife 63, and the side of the rotating sleeve 65 is also provided with a tension spring 64.

[0035] By adopting the above technical solution, the tension spring 64 applies kinetic energy to the vibrating striking rod 61. When the metal striking head 62 at the end of the vibrating striking rod 61 falls, it strikes the shell. The vibration generated during the striking causes the peel to separate from the nut shell. Furthermore, the slotted blade 63 at the bottom of the metal striking head 62 can cut the peel, causing it to crack open and making it easier to peel off, thereby improving the peeling effect.

[0036] Furthermore, the side support 5 includes symmetrically arranged support plates 51, with a support crossbar 56 fixedly connected between the two support plates 51, and rotating sleeves 65 arranged in a rectangular array around the outside of the support crossbar 56.

[0037] More specifically, a spring hanging rod 55 is provided above the support crossbar 56, and both ends of the spring hanging rod 55 are fixedly connected to the support upright plate 51.

[0038] One end of the tension spring 64 is engaged with the spring rod 55, and the other end is engaged with the perforated lug 66 integrally provided at the end of the rotating sleeve 65.

[0039] Furthermore, a rotating shaft 52 is movably connected between the symmetrical support plates 51, and a transmission pulley 54 is fixedly connected through the rotating shaft 52 through the support plate 51. Moreover, a linkage belt 14 is sleeved on the outer side of the transmission pulley 54.

[0040] The rotating shaft 52 is fixedly connected in a rectangular array with cylindrical cams 53 corresponding to the vibrating striking rod 61, and the cylindrical cams 53 are located below the vibrating striking rod 61.

[0041] Furthermore, the shell and fruit conveying mechanism 4 includes shell and fruit positioning seats 44 arranged in a ring array, and each shell and fruit positioning seat 44 is provided with a positioning groove 45 corresponding to the metal striking head 62, and the inner side of the positioning groove 45 is provided with a cross-shaped opening knife 46 fixedly connected to the shell and fruit positioning seat 44.

[0042] More specifically, both ends of the shell positioning seat 44 are provided with drive rollers 41, and both ends of the drive rollers 41 are integrally provided with support shafts 42. Furthermore, each side of the support shaft 42 is interference-fitted with a sliding bearing seat 43 that is fixedly connected to the mounting frame 2. One end of the support shaft 42 is also fixedly connected to a drive disc 9.

[0043] By adopting the above technical solution, the rectangular array of positioning grooves 45 opened on the shell positioning seat 44 can position the shelled fruit and prevent it from rolling when it is struck. In addition, the cross-shaped opening knife 46 inside the positioning groove 45, together with the metal striking head 62, divides the bottom peel, reduces the area of ​​the peel, thereby reducing the contact area between the peel and the nut shell, making it easier for the peel to fall off the nut shell quickly, and further improving the peeling effect of macadamia nuts.

[0044] Furthermore, the drive disc 9 includes a driven gear 91 and a large pulley 92 coaxially arranged, and the driven gear 91 and the large pulley 92 are fixedly connected. In this case, the end of any one of the rotating shafts 52 is fixedly connected to a driving pulley 10 corresponding to the large pulley 92, and a transmission belt 15 is used for transmission between the driving pulley 10 and the large pulley 92.

[0045] Furthermore, a drive motor 8 is fixedly connected to the side of the mounting frame 2, and the end of the drive motor 8 is interference-fitted with a drive gear 11 that is connected to the driven gear 91.

[0046] More specifically, one end of the mounting frame 2 is fixedly connected to an inclined discharge hopper 3, while the other end of the mounting frame 2 is provided with a feed hopper 7 fixedly connected to the top of the mounting frame 2;

[0047] The inner side of the feed hopper 7 is fixedly connected with partitions in a rectangular array, and the partitions are staggered with the positioning grooves 45.

[0048] By adopting the above technical solution, through the transmission cooperation between the driven gear 91 and the driving gear 11, the drive motor 8 drives the shell fruit conveying mechanism 4 to rotate through the driven gear 91. The driven gear 91 and the large pulley 92 rotate synchronously. Then, through the transmission cooperation between the drive belt 15 and the driving pulley 10, the rotating shaft 52 is driven to rotate. The cylindrical cam 53 on the rotating shaft 52, corresponding to the vibrating striking rod 61, can make the end of the vibrating striking rod 61 swing up and down continuously, and continuously strike the shell fruit.

[0049] Furthermore, the mounting frame 2 is provided with a vibrating peeling screen 1 located below the discharge hopper 3 at one end. The bottom of the vibrating peeling screen 1 is movably connected to a fixed frame 12. A crank connecting rod mechanism is provided between the fixed frame 12 and the vibrating peeling screen 1. One end of the crank connecting rod mechanism is driven by a rotary motor 13 fixedly connected to the fixed frame 12.

[0050] Furthermore, both ends of the crank-connecting rod mechanism are movably connected to the fixed frame 12, and the middle position of the crank-connecting rod mechanism is also movably connected to the lower part of the vibrating peeling screen 1. The rotary motor 13 drives the vibrating peeling screen 1 to move up and down rapidly through the crank-connecting rod mechanism, vibrating the shelled fruit on the vibrating peeling screen 1, causing the peel to pass through the vibrating peeling screen 1 and fall downwards, while the nuts roll along the inclined direction of the vibrating peeling screen 1.

[0051] Furthermore, the outer side of the vibrating peeling screen 1 is movably connected with swing rods in a rectangular array, and the other end of the swing rods is movably connected to the fixed frame 12. The rotary motor 13 drives the crank in the crank-rocker mechanism to make circular motion, and the circular motion of the crank is converted into the reciprocating linear motion of the vibrating peeling screen 1 through the connecting rod. When the crank rotates, the connecting rod pushes the vibrating peeling screen 1 to make reciprocating motion within a certain stroke, so that the nuts on the vibrating peeling screen 1 are subjected to vibration and pushing action, and the peel is separated from the nuts by the vibration.

[0052] The working principle of this utility model is as follows: In use, the shells are first placed into the feed hopper 7. The partition in the feed hopper 7 diverts the shells and guides them into the positioning groove 45 on the sliding bearing seat 43. The drive motor 8 drives the drive roller 41 on the support shaft 42 to rotate through the meshing between the drive pulley 10 and the driven gear 91, thereby moving the shell positioning seats 44 arranged in a rectangular array. Simultaneously, the large pulley 92, integrated with the driven gear 91, drives the rotating shaft 52 to rotate through the transmission belt 15 and the drive pulley 10. The cylindrical cam 53 on the rotating shaft 52 rotates continuously, pushing the vibrating striking rod 61 upwards. The tension spring 64 at the end of the vibrating striking rod 61 applies kinetic energy to the vibrating striking rod 61. When the metal striking head 62 at the end of the vibrating striking rod 61 falls, it impacts the metal striking head 6... The shells below are struck, and the vibration generated during the striking separates the peel from the nut shell. The flat blade 63 at the bottom of the metal striking head 62 and the cross blade 46 in the positioning groove 45 work together to cut the peel into multiple pieces, improving the separation effect of peel and nut shell during peeling. After being struck, the shells continue to move with the shell positioning seat 44 until they rotate to one end, and then fall into the vibrating peeling screen 1 through the discharge hopper 3. The rotary motor 13, which is fixed to the side of the fixed frame 12, drives the crankshaft connected to the bottom of the vibrating peeling screen 1 to rotate, thereby vibrating the vibrating peeling screen 1 and separating the cut and struck shells. The peel falls through the holes on the vibrating peeling screen 1 and the nuts move to the other end of the vibrating peeling screen 1 through vibration. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
