Description

Technical Field

[0001] This utility model relates to the field of walnut peeling equipment, specifically to a walnut peeling device. Background Technology

[0002] There are several methods for removing the green husk from walnuts, including but not limited to the following four:

[0003] (1) Composting method: This is a traditional Chinese method for peeling walnuts. Adding a 10 cm thick layer of wheat chaff or dry leaves to the pile can increase the temperature inside the pile, promote fruit ripening, and speed up the peeling process. Generally, the pile is composted for 3 to 5 days. When more than 50% of the green husks have separated from the shell or cracked, they can be peeled by tapping them with a stick. For those that have not yet peeled, the pile can be composted for several more days until all the husks have been peeled.

[0004] (2) Chemical method: After harvesting, dip the fruit in a 0.3% to 0.5% ethephon solution for about half a minute, then pile them in a cool place or indoors with a thickness of about 50 cm, maintaining a temperature of 30℃ and a relative humidity of 80% to 90%. After about 5 days, the peeling rate can reach more than 95%. If a layer of wheat bran or dry grass of about 10 cm is added on top of the pile, the peeling will occur in about 2 days.

[0005] (3) Spray ethephon before harvest: When the walnuts are close to maturity, add 800-1200 mg of ethephon to 1 kg of water to make a solution. Spray the solution on the surface of the walnut fruit 10 days before harvest. Harvest 10 days later. The cracking rate can reach 95%. After harvesting, ferment for 1-2 days.

[0006] (4) Freeze-thaw method for removing green husks: a method that uses low temperature to freeze the green husks of walnuts and then melts them at high temperature to remove the green husks.

[0007] The above methods can effectively remove the green husk of walnuts, but they have the drawbacks of low peeling efficiency and long time consumption. Therefore, a device that can mechanically remove the green husk of freshly picked walnuts is needed. Utility Model Content

[0036] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0037] This utility model provides a walnut peeling device, as shown in Figures 1-11. The walnut peeling device includes: a feeder 1, a peeling machine 2 connected to the feeder 1, a vibrating conveyor 3 connected to the peeling machine 2, and a transport machine 4 connected to the vibrating conveyor 3. The peeling machine 2 includes: a frame 5, peeling rollers 6 mounted on the frame 5, multiple peeling curved blades 7 mounted below the peeling rollers 6, and guide rails 8 connected at one end to the peeling curved blades 7 and at the other end to the feeder 1. The number of guide rails 8 is the same as the number of peeling curved blades 7. The function of the guide rails 8 is to feed walnuts between the peeling rollers 6 and the peeling curved blades 7. The feeder 1 feeds walnuts to the guide rails 8 in a rhythmic manner. The peeling roller 6 includes: a first rotating shaft 9 mounted on the frame 5; multiple rotating walnut transport discs 10 mounted on the first rotating shaft 9; a three-claw peeling disc 11 mounted inside the walnut transport discs 10 and rotating with the first rotating shaft 9; a connecting sleeve 12 mounted on the first rotating shaft 9 and connecting adjacent walnut transport discs 10; a first driving mechanism for driving the rotation of all walnut transport discs 10; a second driving mechanism for driving the rotation of the first rotating shaft 9; the end of the guide rail 8 facing between the walnut transport discs 10 and the peeling curved blade 7; the walnut transport discs 10 and the peeling curved blade 7 corresponding one-to-one; and the rotational speed of the three-claw peeling disc 11 being higher than that of the walnut transport discs 10. A set of vertically arranged walnut transport trays 10 and peeling curved blades 7 form a peeling component. A connecting sleeve 12 connects to the walnut transport trays 10. A first drive mechanism drives the walnut transport trays 10 to rotate, allowing the walnuts fed by the guide rail 8 to pass between the peeling rollers 6 and the peeling curved blades 7. Meanwhile, a three-jaw peeling disc 11 rotates at a higher speed than the walnut transport trays 10, removing the green husks from the walnuts. The number of walnut transport trays 10 corresponds to the number of peeling components, allowing the same number of walnuts to be peeled simultaneously.

[0038] The walnut transport tray 10 includes: a first toothed disc 13, a second toothed disc 14 concentric and parallel to the first toothed disc 13, and two symmetrically arranged on the edges of the first toothed disc 13 and connected.

[0039] The second toothed disc 14 has a cleaning component 15; the cleaning component 15 is n-shaped, one end of the cleaning component 15 is connected to the first toothed disc 13, and the other end of the cleaning component 15 is connected to the second toothed disc 14. The top of the cleaning component 15 is provided with a protruding prying tool 16. Both the first toothed disc 13 and the second toothed disc 14 are provided with multiple through holes, which can prevent the green walnut skin from getting stuck. The prying tool 16 rotates with the first toothed disc 13 and the second toothed disc 14 to remove the walnut skin stuck in the peeling curved knife 7. The width between the first toothed disc 13 and the second toothed disc 14 should be smaller than the diameter of the walnut. Walnuts that are too small will fall off, forming the initial screening of the walnuts.

[0040] The connecting sleeve 12 includes: a sleeve 17, a bearing 18 disposed within the sleeve 17 and fitted onto the first rotating shaft 9, and connecting ends 19 disposed on both sides of the sleeve 17; a first connecting hole 20 is provided at the center of the first geared disc 13, and a second connecting hole 22 is provided at the center of the second geared disc 14; the connecting end 19 is a circular tube 23 inserted into the first connecting hole 20 or the second connecting hole 22, and the circular tube 23 is provided with a circular ring 24 bolted to the first geared disc 13 or the second geared disc 14. The connecting sleeve 12 connects adjacent walnut transport discs 10, connecting all the walnut transport discs 10 in series into a whole, and is driven to rotate by a first driving mechanism, not synchronously with the rotation of the first rotating shaft 9.

[0041] The first drive mechanism includes: a first sprocket 25 mounted on the sleeve 17; a second shaft 26 mounted on the frame 5; a second sprocket 27 mounted on the second shaft 26 and corresponding to the first sprocket 25; a first chain 28 connecting the first sprocket 25 and the second sprocket 27; a third sprocket 29 mounted on the second shaft 26; a first servo motor 32 mounted on the frame 5; a first reducer 33 connected to the first servo motor 32; a fourth sprocket 30 mounted on the first reducer 33; and a second chain 31 connecting the third sprocket 29 and the fourth sprocket 30. The first servo motor 32 drives the first reducer 33, the first reducer 33 drives the fourth sprocket 30, the fourth sprocket 30 drives the third sprocket 29, the third sprocket 29 drives the second sprocket 27, and the second sprocket 27 drives the first sprocket 25.

[0042] The first sprocket 25 drives the connecting sleeve 12 to rotate, and the connecting sleeve 12 drives the walnut transport tray 10 to rotate. Not all sleeves 17 need to be equipped with the first sprocket 25; the first sprocket 25 can be installed at appropriate intervals.

[0043] The three-jaw peeling disc 11 includes: a disc 34 disposed on the first rotating shaft 9 and located between the first toothed disc 13 and the second toothed disc 14; three base blocks 35 arranged in a circumferential array on the sidewall of the disc 34; and peeling claws 36 disposed on the base blocks 35. Each peeling claw 36 includes a connecting rod 37 connected to the base blocks 35, and a hook 38 bent outwards at the tail end of the connecting rod 37. The base blocks 35 have two parallel support members 39, with a circular shaft 40 between the support members 39. The connecting rod 37 has a circular hole rotatably connected to the circular shaft 40. A first spring 41 is provided at the front end of the connecting rod 37, connecting to the sidewall of the disc 34. A threaded hole is provided on the connecting rod 37 between the first spring 41 and the circular hole, and a screw 42 is disposed within the threaded hole. The screw 42 has a screw located on the connecting rod 37. A first nut 43 is provided on one side, and a second nut is provided on the screw 42 on the other side of the connecting rod 37.

[0044] 44. The lower end of the screw 42 can abut against the top of the base block 35. The working principle of the three-claw peeling disc 11 is as follows: Walnuts with green skin pass between the walnut transport disc 10 and the peeling curved blade 7. The front end of the digging hook 38 contacts the green skin and digs it off. If the digging hook 38 is fixed, it will either jam the walnut or the peeling will not be complete. Therefore, the first spring 41 is designed to pull the front end of the connecting rod 37, so that the digging hook 38 has a retraction effect while making maximum contact with the green skin, which can prevent the digging hook 38 from getting stuck. At the same time, the screw 42, the first nut 43 and the second nut 44 limit the maximum retraction distance of the digging hook 38 to prevent the digging hook 38 from not being able to dig off the green skin at all. The three peeling claws 36 can achieve the effect of gradually removing the green skin. It should be noted that the number of peeling claws 36 is not limited to three, but can be three or more.

[0045] The peeling curved blade 7 includes: a round rod 46 mounted on the frame 5 and spatially parallel to the first rotating shaft 9; a long rod 47 hinged to the round rod 46; and two parallel arc blades 48 mounted at the other end of the long rod 47, the center of which is concentric with the center of the first toothed disc 13.

[0046] The arc-shaped blades 48 are respectively positioned below the first toothed disc 13 and the second toothed disc 14. The inner side of each arc-shaped blade 48 has serrations. A connecting rod 49 connects the front end of the peeling curved blade 7 to the arc-shaped blade 48. A gantry frame 50 is mounted on the frame 5, and a second spring 51 connects the outer side of each arc-shaped blade 48 to the gantry frame 50. To prevent excessively large walnuts from failing to pass through the gap between the walnut transport disc 10 and the peeling curved blade 7, the arc-shaped blade 48 is connected to the gantry frame 50 via the second spring 51. The tension of the second spring 51 ensures that the walnut remains in contact with the digging hook 38. As the walnut gradually decreases in size, the arc-shaped blades 48, under tension, consistently lift the walnut to contact the digging hook 38, and the peeled walnut skin falls between the arc-shaped blades 48. The walnuts tumble at multiple angles under the action of the walnut transport disc 10 and the three-claw peeling disc 11, thus removing most of the green husk.

[0047] The front end of the frame 5 is provided with a limiting rod 52, which is parallel to the first rotating shaft 9. The lower end of the limiting rod 52 is provided with a vertical baffle 53. The baffle 53 is provided with a number of trapezoidal limiting holes 54 equal to the number of peeling curved blades 7. The front end of the peeling curved blade 7 is provided with a limiting element 76 located within the trapezoidal limiting holes 54. The limiting holes 54 and the limiting rod 52 are used to prevent the arc blade 48 from moving downwards too much, thus preventing the green skin of the walnut from being peeled off. The limiting holes 54 and the limiting element 76 work together to prevent the peeling curved blade 7 from moving left and right and failing to cooperate with the walnut transport tray 10.

[0048] The frame 5 includes a crossbar 55, parallel support arms 56 mounted on the crossbar 55, a first rotating shaft 9 mounted on the support arm 56, a gantry frame 50 mounted on the support arm 56, a second rotating shaft 26 mounted on the gantry frame 50, a round rod 46 between the support arms 56, and a limiting rod 52 between the support arms 56. It also includes the support structure required for mounting the first drive mechanism and the second drive mechanism.

[0049] The second drive mechanism includes a fifth sprocket 57 mounted on the first rotating shaft 9, a second servo motor 58 mounted on the frame 5, a second reducer 59 mounted on the second servo motor 58, a sixth sprocket 61 mounted on the output shaft of the second reducer 59, and the sixth sprocket 61 and the fifth sprocket 57 connected by a third chain 60.

[0050] The feeding machine 1 includes an inclined conveying trough 62, a drive shaft 63 disposed within the conveying trough 62, a driven shaft 64 disposed parallel to the drive shaft 63, a seventh sprocket 65 and an eighth sprocket 66 disposed on the drive shaft 63, a ninth sprocket 67 and a tenth sprocket 68 disposed on the driven shaft 64, a fourth chain 69 connecting the seventh sprocket 65 and the ninth sprocket 67, a fifth chain 70 connecting the eighth sprocket 66 and the tenth sprocket 68, multiple transport rods 72 laid on the fourth chain 69 and the fifth chain 70, and a third drive mechanism for driving the drive shaft 63 to rotate. The transport rods 72 are provided with bowl-shaped recesses 73, and the number of bowl-shaped recesses 73 is equal to the number of peeling curved blades 7. The front end of the conveying trough 62 is provided with a guide 74, which has a slot corresponding to the bowl-shaped recess 73. One end of the guide rail 8 rests in the slot, and the other end of the guide rail 8 is hinged to the arc-shaped blade 48. A hopper 77 is also provided on the inclined conveying trough 62. Walnuts are placed in the hopper 77. The third drive mechanism drives the drive shaft 63 to rotate, which in turn drives the driven shaft 64. This causes the third chain 60 and the fourth chain 69 to rotate the conveyor rod 72, forming a conveyor belt. The bowl-shaped recess 73 should be large enough to hold only one walnut. The walnut is carried within the bowl-shaped recess 73 to the guide 74 and enters the guide rail 8 through the slot. In addition to the third servo motor and its gearbox, the third drive mechanism should also include a metronome to control the speed and rhythm of the conveyor rod 72. The metronome is existing technology. After setting the metronome, the walnuts can be allowed to enter the guide rail 8 one by one. After the green husk of the previous walnut in the same row is removed, the next walnut will enter the guide rail 8. That is to say, the three-claw peeling disc 11 can only remove the green husk of one walnut at a time. Therefore, the number of three-claw peeling discs 11 can be increased in parallel and they can be made to work at the same time to improve the efficiency of removing the green husk.

[0051] The guide rail 8 is only in contact with the slot and is not fixed. The support arm 56 of the frame 5 is equipped with a support rod 71 to keep the guide rail 8 at an angle.

[0052] After the green husks are removed, the walnuts enter the vibrating conveyor 3. Vibrating conveyor 3 is existing technology and will not be described in detail. The bottom of the trough of vibrating conveyor 3 is equipped with sieve holes. The walnuts, after the green husks are removed, pass through the sieve with attached walnuts...

[0053] The green peel will fall off under the vibration and fall through the sieve holes.

[0054] A collection trough 75 is provided below the frame 5 and the material trough to collect the peeled green skin.

[0055] The final transport aircraft 4 can be any existing type of transport aircraft 4, used to transport the walnuts after they have been peeled to another location.

[0056] The working principle of this utility model is as follows:

[0057] The harvested walnuts are destemmed and poured into hopper 77. At the same time, feeder 1, peeling machine 2, vibrating conveyor 3, and conveyor 4 are started. The walnuts enter the peeling machine from feeder 1 along guide rail 8. Under the action of peeling roller 6, the green skin is removed. Then, the walnuts enter the vibrating conveyor 3 to shake off the attached green skin and are sent away by conveyor 4.

[0058] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
