Description

Technical Field

[0001] This utility model relates to the field of cashew nut shelling machine technology, and in particular to a feeding structure for a cashew nut shelling machine. Background Technology

[0002] Cashews have hard shells, so they need to be shelled during processing to remove the cashew kernels from the shells. Currently, cashew shelling equipment usually places the cashews in a specific conveyor channel and then uses a shelling knife to break open the shells to complete the shelling process.

[0003] Because shell conveyors typically use metal chains with sprocket drives, during the conveying process, the metal chain bears weight and may sag at locations where the support is insufficient. This can cause the load-bearing components of the conveyor to come into contact with the feed plate. Over long-term operation, this can lead to wear on the feed plate and reduce its service life. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a feeding structure for a cashew shelling machine, which solves the technical problem that the metal chain will sag due to insufficient support caused by the weight during the feeding process, which may cause the load-bearing parts of the conveyor bar to come into contact with the feeding plate, resulting in wear of the feeding plate and reduced service life under long-term operation.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0047] The following is in conjunction with the appendix Figures 1 to 12 To provide a further description, this utility model discloses a feeding structure for a cashew shelling machine, including a frame 1, a feeding device 2 at the upper end of the frame 1, a discharge hopper 12 at the lower end of the frame 1, and a feeding mechanism between the feeding device 2 and the discharge hopper 12.

[0048] The feeding mechanism includes a feeding device 3 with a pusher plate 33 and a pushing device 4 with a pusher plate 44. The pushing device 4 and the feeding device 3 are connected by a feeding plate 5 with a feeding groove 50. The pushing device 4 is located inside the feeding device 3 and the pushing plate 44 on the pushing device 4 is inserted into and passes through the feeding plate 5 and extends into the feeding groove 50. The front end of the feeding device 3 is provided with an opening device, which includes an upper opening mechanism and a lower opening mechanism 7.

[0049] Both ends of the feeding device 2 are provided with a first guide plate 10 and a second guide plate 11. The first guide plate 10 is provided on both sides of the feeding device 3, and the second guide plate 11 is provided on both sides of the pushing device 4. The second guide plate 11 is located below the first guide plate 10 and is in contact with the pushing chain 42 surrounding the pushing device 4. The lower opening mechanism 7 is provided inside the feeding device 3 and is connected to the end of the feeding plate 5.

[0050] The upper shell opening mechanism and the lower shell opening mechanism 7 are positioned opposite each other with a gap between them. The upper shell opening mechanism is provided with an upper shell opening group 6 and a support frame 60. There are 12 upper shell opening groups 6, which are set on the support frame 60. Six upper shell opening groups 6 form a group. A feeding limit device 8 is also provided between the two groups of upper shell opening groups 6.

[0051] In a preferred embodiment, the feeding device 2 includes a feeding hopper 20, a feeding brush 21, a feeding main shaft 22, a feeding secondary shaft 23, a feeding chain 24, and a feeding plate 25. The feeding brush 21 is mounted on a brush roller 27 and rotates via the brush roller 27. A portion of the feeding brush 21 extends into the interior of the feeding hopper 20, and its lower end contacts the end face of the feeding plate 25. The two ends of the feeding main shaft 22 and the feeding secondary shaft 23 are connected by the feeding chain 24. The four-phase connection is achieved by laying the feeding plate 25 in a circular manner between the feeding chains 24 at both ends of the feeding main shaft 22 and the feeding secondary shaft 23. The upper surface of the feeding plate 25 is provided with 12 inwardly recessed feeding grooves 26. As the brush roller 27 rotates toward the feeding hopper 20, it blocks the cashews outside the feeding grooves 26 into the feeding hopper 20. The cashews inside the feeding grooves 26 experience less resistance and can enter the feeding grooves 50 on the feeding plate 5 as the feeding chain 24 rotates.

[0052] In a preferred embodiment, the feeding device 3 includes a feeding main shaft 30, a feeding secondary shaft 31, a feeding chain 32, and a pusher plate 33. There are two feeding chains 32, which are respectively sleeved on both ends of the feeding main shaft 30 and the feeding secondary shaft 31. The two ends of the pusher plate 33 are respectively connected to the feeding chains 32 at both ends of the feeding main shaft 30 and the feeding secondary shaft 31. There are two or more pusher plates 33, which are laid on the feeding chains 32 at both ends of the feeding main shaft 30 and the feeding secondary shaft 31, and rotate with the rotation of the feeding chains 32.

[0053] In a preferred embodiment, there are two first guide plates 10, which are respectively arranged on both sides of the frame 1. The first guide plate 10 is provided with a chain channel 101 that is recessed inward. The upper part of the feed chain 32 enters and passes through the chain channel 101 of the first guide plate 10 and is then sleeved between the feed main shaft 30 and the feed auxiliary shaft 31.

[0054] In a preferred embodiment, the feeding device 4 further includes a feeding main shaft 40, a feeding secondary shaft 41, a feeding chain 42, and a connecting horizontal plate 43. The second guide plate 11 is located between the feeding main shaft 40 and the feeding secondary shaft 41. There are two feeding chains 42, which are respectively sleeved on both ends of the feeding main shaft 40 and the feeding secondary shaft 41. Both ends of the connecting horizontal plate 43 are respectively connected to the feeding chains 42 at both ends of the feeding main shaft 40 and the feeding secondary shaft 41. The feeding baffle 44 is disposed on the upper end surface of the connecting horizontal plate 43.

[0055] In a preferred embodiment, there are two second guide plates 11, which are respectively disposed on both sides of the frame 1. The two ends of the guide plates 11 are arc-shaped. The second guide plates 11 are disposed inside the annular push chain 42 and are in contact with the upper part of the chain roller. The second guide plates 11 are also provided with two mounting blocks 110 and are fixed to both sides of the frame 1 by the mounting blocks 110.

[0056] In a preferred embodiment, there are 12 sets of upper shell-opening assemblies 6 arranged side by side on the support frame 60. Each upper shell-opening assembly 6 includes a lifting rod 61, a lifting spring 62, a lifting slide rail 63, a lifting slider 64, an upper blade plate 65, and an upper shell-opening blade 66. A first V-shaped block 691 is provided adjacent to the upper shell-opening blade 66. Specifically, the lifting rod 61 is fitted with the lifting spring 62 and fixed to the support frame 60 by a plum nut 69. The lifting slider 64 is fixed to the support frame 60 and connected to the lifting slide rail 63 between it and the connecting strip 68. The lower end of the lifting rod 61 is connected to the upper blade plate 65 through the connecting strip 68. The upper shell-opening blade 66 is disposed on the upper blade plate 65 and passes through the contour feeding groove 67 of the upper blade plate 65. The first V-shaped block 691 is disposed at the end of the contour feeding groove 67. One end of the lowering spring 62 abuts against the lower end of the support frame 60, while the other end of the lifting spring 62 abuts against the upper end of the connecting strip 68. Therefore, under the action of the lifting spring 62, the upper shell assembly 6 always maintains downward pressure. When the cashew nut passes through the upper shell assembly and the lower shell assembly 7 under the push of the pusher plate 33, the cashew nut will push up the upper shell knife 66 assembly, causing the lifting spring 62 to move upward. During this process, the lifting slider 64 cooperates with the lifting slide rail 63 to limit the movement. The lifting spring 62 maintains downward pressure while the upper shell knife 66 and the lower shell knife 72 contact and break the upper and lower parts of the cashew nut shell, respectively. The broken shell crack will contact the first V-shaped block 691 and the second V-shaped block 73 and be completely cracked by the protrusions 87 of the first V-shaped block 691 and the second V-shaped block 73.

[0057] In a preferred embodiment, the lower shell-opening mechanism 7 includes a left blade holder 70, a right blade holder 71, a lower shell-opening blade 72, and a second V-shaped block 73. A contoured channel 74 is formed between the left blade holder 70 and the right blade holder 71. The lower shell-opening blade 72 is disposed within the contoured channel 74 between the left blade holder 70 and the right blade holder 71. The second V-shaped block 73 is inserted from the V-shaped notch formed at the ends of the left blade holder 70 and the right blade holder 71 and abuts against the end of the lower shell-opening blade 72. The lower shell-opening blade 72 and the second V-shaped block 73 extend above the bottom of the contoured channel 74, so that after the lower shell-opening blade 72 cuts open the nut shell, it inserts into the cut crack starting from the tip of the second V-shaped block 73. The crack is then widened from small to large according to the triangular shape of the second V-shaped block 73 to break open the lower part of the nut shell. In this embodiment, the number of lower shell-opening blades 72 is the same as the number of upper shell-opening blades 66.

[0058] In a preferred embodiment, the feeding limiting device 8 includes a mounting rod 81, a connecting plate 82, an adjusting bolt 83, an adjusting plate 84, and guide wheels 85. The mounting rod 81 is disposed between the two sets of upper shell groups 6 and connected to the support frame 60. The connecting plate 82 is disposed at the lower end of the mounting rod 81 and connected to the adjusting plate 84. The adjusting bolt 83 is inserted into and passes through the connecting plate 82 and is connected to the adjusting plate 84. The height of the adjusting plate 84 is adjusted by rotating the adjusting bolt 83. The guide wheels 85 are disposed at the lower end of the adjusting plate 84. There are two or more guide wheels 85 arranged side by side at the lower end of the adjusting plate 84 to limit the push plate 33 passing through the upper shell group 6.

[0059] In a preferred embodiment, the connecting plate 82 has an inwardly recessed lifting adjustment portion 86, and the upper part of the adjusting plate 84 protrudes upward to form a protrusion 87, which is disposed in the lifting adjustment portion 86. The adjusting bolt 83 is inserted and passes through the upper end of the connecting plate 82, extends into the lifting adjustment portion 86, and connects with the protrusion 87 of the adjusting plate 84. The connecting plate 82 also has two strip holes that penetrate the lifting adjustment portion 86 and are connected to the adjusting plate 84 by bolts.

[0060] In this embodiment, the connection between each chain and each shaft is achieved by the corresponding sprockets mounted on each shaft. The driving device is a motor 9. In addition, the chain used for transmission is a standard chain, and the chain used for conveying is a bent plate chain. This is common knowledge and will not be described in detail.

[0061] In summary, the first guide plates on both sides of the feeding device lift the feeding chains on both sides to keep them in a relatively stable state, preventing them from sagging due to their own weight and the weight of the pusher plate, which would cause friction between the pusher plate and the feeder plate and damage to them. In addition, the second guide plates on both sides of the pushing device can keep the pusher plate installed on the pusher chain at a preset height to push the cashews placed on the feeding groove. The feeding limit device on the shell opening device can limit the pusher plate, making it more stable.

[0062] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications and variations to the above embodiments, but such modifications are all included within the broad scope of the foregoing disclosure, drawings and claims.
