Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a shelling device and a peanut shelling machine. Background Technology

[0002] Peanuts, as a widely cultivated oilseed and cash crop globally, occupy an important position in food processing and oil production. With the continuous expansion of the peanut industry, the requirements for peanut shelling efficiency and quality are increasing. Traditional manual shelling methods are not only labor-intensive and inefficient but also costly, making them unsuitable for large-scale production. Therefore, peanut shelling machines have emerged as a key piece of equipment for improving shelling efficiency.

[0003] Existing peanut shelling machines typically use iron sheets directly welded to the extrusion rollers for the extrusion plates. While this achieves basic shelling, the shelling effect is poor, resulting in a high rate of peanut kernel breakage and decreased product quality, impacting subsequent sales and processing. Furthermore, any partial wear on the overall structure necessitates replacing the entire extrusion roller, leading to high maintenance costs and prolonged downtime, severely hindering production continuity and economic efficiency. Therefore, developing a novel shelling device has become a pressing issue for those skilled in the art. Utility Model Content

Detailed Implementation

[0038] To better understand the purpose, structure, and function of this invention, the following detailed description of a shelling device and peanut shelling machine of this utility model is provided in conjunction with the accompanying drawings.

[0039] Example 1

[0040] like Figure 1-12As shown, the shelling device of this utility model includes a shelling mechanism for shelling peanuts. The shelling mechanism comprises a first shelling mechanism 5 and a second shelling mechanism 6. By dividing the shelling mechanism into the first shelling mechanism 5 and the second shelling mechanism 6, peanut shelling can be divided into two steps. First, peanuts are placed in the first shelling mechanism 5 for shelling. Peanuts not shelled in the first shelling mechanism 5 are then placed in the second shelling mechanism 6 for shelling. The first shelling mechanism 5 is equipped with a first pressing mechanism, the function of which is to shell the peanuts through the first pressing mechanism. The first pressing mechanism includes a pressing roller 2 and a first arc grid 3. A pressing roller 2 and a first arc-shaped grid 3 are arranged on the upper part of the machine so that they cooperate with each other. The pressing roller 2 rotates to squeeze the peanuts against the first arc-shaped grid 3, thereby separating the peanut kernels from the shells. The pressing roller 2 is equipped with a pressing plate 203. By setting the pressing roller 2 with the pressing plate 203, the peanuts are squeezed by the pressing plate 203 to complete the shelling action. The pressing plate 203 is a rubber sheet. The rubber sheet is used as the pressing plate 203 because it can buffer the extrusion force through its own elastic deformation, thereby reducing the damage of the peanut kernels during the shelling process. The pressing plate 203 is equipped with a connecting piece 204. The pressing plate 203 is connected to the first connecting plate 202 through the connecting piece 204. The 03 is equipped with a connector 204, and the extrusion plate 203 is connected to the first connecting plate 202 through the connector 204, so that the connector 204 fixes the extrusion plate 203 to the first connecting plate 202. The connector 204 is a quick-release connection. When the extrusion plate 203 is severely worn or damaged, it can be replaced through the connector 204, which can effectively reduce the equipment's maintenance time and maintenance costs. The first arc grid 3 is equipped with a first grid bar 303. By setting the first grid bar 303 on the first arc grid 3, it can cooperate with the extrusion plate 203 to complete the peanut shelling action. The second shelling mechanism 6 is equipped with a second extrusion mechanism, which includes an extrusion plate 203. The pressure roller 2 and the second arc-shaped grid 4 are arranged in the second extrusion mechanism to cooperate with each other to form a second shelling process. The second arc-shaped grid 4 is provided with second grid bars 403. By setting the second grid bars 403 on the second arc-shaped grid 4, it can cooperate with the extrusion plate 203 to extrude and shell the peanuts. The spacing of the second grid bars 403 is smaller than the spacing of the first grid bars 303, so that peanuts that were not shelled in the first shelling can be shelled in the second shelling. The extrusion plate 203, the first arc-shaped grid 3, and the second arc-shaped grid 4 can all be replaced according to different needs. For example, the first arc-shaped grid 3 with a larger gap between the first grid bars 303 can be replaced.

[0041] In this embodiment, the extrusion roller 2 is provided with a first fixing plate 201. By providing the first fixing plate 201 on the extrusion roller 2, the extrusion roller 2 can be fixed on the transmission shaft by the first fixing plate 201, and the first fixing plate 201 can be rotated by the transmission shaft. The first fixing plate 201 is connected to the first connecting plate 202. By connecting the first fixing plate 201 and the first connecting plate 202, multiple first connecting plates 202 are fixed to the first fixing plate 201. During operation, the first connecting plates 202 rotate with the first fixing plate 201. The first arc grid 3 is provided with a second connecting plate 302, and the second connecting plate 302 is provided with a second fixing plate 301. By providing the second fixing plate 301 on the first arc grid 3, This allows the first arc grid 3 to be fixed in the first shelling mechanism 5 via the second fixing plate 301; the second connecting plate 302 is provided with a first grid bar 303, wherein the first grid bar 303 is evenly distributed according to the required gap and cooperates with the extrusion roller 2; the first grid bar 303 is provided with a first fixing bar 304, which fixes the first grid bar 303, making its structure more stable and reducing the damage rate; the extrusion sheet 203 is a rubber sheet, which can buffer the extrusion force through its own elastic deformation, and will not damage the peanut kernel due to excessive hardness.

[0042] In this embodiment, the second arcuate grid 4 is provided with a third connecting plate 402, and the third connecting plate 402 is provided with a third fixing plate 401. By providing the third connecting plate 402 and the third fixing plate 401 on the second arcuate grid 4, the third fixing plate 401 can fix the second arcuate grid 4 in the second peeling mechanism 6 and connect it to the third connecting plate 402. The third connecting plate 402 is provided with a second grid bar 403. By providing the second grid bar 403 on the third connecting plate 402, the second grid bar 403 can be evenly distributed on the third connecting plate 402 according to the required spacing. The second grid bar 403 is provided with a second fixing bar 404. By providing the second fixing bar 404 on the second grid bar 403, the second fixing bar 404 reinforces the second grid bar 403, making the overall structure of the second arcuate grid 4 more stable and enabling better peeling work.

[0043] The shelling mechanism in this embodiment includes an air separation mechanism 7. By setting the air separation mechanism 7 below the shelling mechanism, the air separation mechanism 7 blows out the lighter peanut shells as the shelled peanut kernels and shells fall downwards. The air separation mechanism 7 includes a first fan 18, a fourth connecting plate 1801, and a first fan blade 1802. By setting the first fan 18 inside the air separation mechanism 7, the first fan 18 can blow out the peanut shells. The air separation mechanism 7 includes a first outlet 21. By setting the first outlet 21 below the air separation mechanism 7, the peanut shells are blown away after passing through the air separation mechanism 7, and the remaining peanut kernels and unshelled peanuts fall through the first outlet 21. The air separation mechanism 7 also includes a third outlet 19. By setting the third outlet 19 on the air separation mechanism 7, the peanut shells that have passed through the air separation mechanism 7 are blown to the outside through the third outlet 19.

[0044] In this embodiment, the first outlet 21 is equipped with a screening mechanism 8. By setting the screening mechanism 8 below the first outlet 21, peanut kernels and unpeeled peanuts that have passed through the air separation mechanism 7 fall from the first outlet 21 into the screening mechanism 8 for screening. The screening mechanism 8 is equipped with a first fan 18. By setting the first fan 18 inside the screening mechanism 8, the peanut shells that have fallen through the air separation mechanism 7 are blown into the air separation mechanism 7 by the first fan 18, and then blown to the outside by the air separation mechanism 7. The screening mechanism 8 is equipped with a first screening mechanism 801. By setting the first screening mechanism 801 on the screening mechanism 8, the peanut kernels that have passed through the screening mechanism 8 are further screened by the first screening mechanism 801 for the next step. Screening; the screening mechanism 8 is also provided with a second screening mechanism 802. By providing a second screening mechanism 802 on the screening mechanism 8, the smaller unshelled peanuts that have passed through the screening mechanism 8 will flow out through the second screening mechanism 802, while those that need to be shelled a second time will be sent into the conveying mechanism 22 by the second screening mechanism 802; the second screening mechanism 802 is provided with a second outlet 23. By providing a second outlet 23 on the second screening mechanism 802, the smaller unshelled peanuts will flow out through the second outlet 23; the second screening mechanism 802 is also provided with a conveying mechanism 22. By providing a conveying mechanism 22 on the second screening mechanism 802, the peanuts that need to be shelled a second time will be sent into the conveying mechanism 22 by the second screening mechanism 802.

[0045] In this embodiment, a pneumatic conveying mechanism 9 is provided at the outlet of the conveying mechanism 22. By providing the pneumatic conveying mechanism 9 at the outlet of the conveying mechanism 22, the unshelled peanuts in the conveying mechanism 22 are fed into the pneumatic conveying mechanism 9. The pneumatic conveying mechanism 9 is provided with a second fan 17, a fifth connecting plate 1701, and a second fan blade 1702. By providing the second fan 17 on the pneumatic conveying mechanism 9, the second fan 17 blows the unshelled peanuts in the pneumatic conveying mechanism 9 into the second shelling mechanism 6.

[0046] In this embodiment, the first shelling mechanism 5 is provided with a first inlet 501, which allows peanuts to be shelled to be placed into the first inlet 501; the second shelling mechanism 6 is provided with a second inlet 601, which allows unshelled peanuts in the pneumatic conveying mechanism 9 to be blown into the second inlet 601 by the wind power of the second fan 17 for a second shelling; the second shelling mechanism 6 is provided with an air outlet 602, which allows the air transmitted from the pneumatic conveying mechanism 9 to the second shelling mechanism 6 to be discharged from the air outlet 602.

[0047] This utility model discloses a peanut shelling machine, including a frame 11, a drive mechanism 10 on the frame 11, which provides power to the entire peanut shelling machine; a first shelling mechanism 5 with a first channel 27, through which unshelled peanuts, peanut kernels, and peanut shells are discharged after being shelled in the first shelling mechanism 5; a second shelling mechanism 6 with a second channel 28, through which unshelled peanuts, peanut kernels, and peanut shells are discharged; and a third channel 29 on an air separation mechanism 7, connecting the first channel 27 and the second channel 29. The peanut kernels and shells flowing out of channel 28 flow into the third channel 29; by providing an inclined surface 2901 in the third channel 29, when the air separation mechanism 7 blows the peanut shells out by wind, it can prevent the peanut kernels from being blown out as well; by providing a fourth channel 30 in the first outlet 21, the unpeeled peanuts and peanut kernels flow out in this channel; by providing a fifth channel 31 in the screening mechanism 8, the fan in the screening mechanism 8 can blow air upward through the fifth channel 31, causing some peanut shells that were not blown away and fell through the fourth channel 30 to be blown back; by providing a sixth channel 32 in the pneumatic conveying mechanism 9, the unpeeled peanuts can be blown through the sixth channel 32 to the second shelling mechanism 6 for a second shelling.

[0048] In this embodiment, the drive mechanism 10 and the screening mechanism 8 are connected by a first transmission mechanism 12, which transmits power from the drive mechanism 10 to the screening mechanism 8. The frame 11 is connected to the intermediate shaft 25, and the first transmission mechanism 12 and the intermediate shaft 25 are connected by a second transmission mechanism 13, which transmits power from the first transmission mechanism 12 to the intermediate shaft 25. The intermediate shaft 25 is connected to the air separation mechanism 7 by a third transmission mechanism 14, which transmits power from the intermediate shaft 25 to the air separation mechanism 7. The three transmission mechanisms 14 transmit power to the air separation mechanism 7; the intermediate shaft 25 is connected to the first shelling mechanism 5 through the fourth transmission mechanism 15, so that the power on the intermediate shaft 25 is transmitted to the first shelling mechanism 5; the first shelling mechanism 5 and the second shelling mechanism 6 are connected through the fifth transmission mechanism 16, so that the power on the first shelling mechanism 5 is transmitted to the second shelling mechanism 6; the frame 11 is equipped with a control switch 24, so that the control switch 24 can control the switching on and off of the entire peanut shelling machine.

[0049] In this embodiment, the screening mechanism 8 is equipped with an auxiliary mechanism, which is movably connected to the frame 11 and the screening mechanism 8. By providing the auxiliary mechanism, the screening mechanism 8 can swing back and forth. The auxiliary mechanism includes a first auxiliary mechanism 803 and a second auxiliary mechanism 804. These two mechanisms movably connect the screening mechanism 8 to the frame 11. The intermediate shaft 25 is equipped with an eccentric mechanism 26. Mechanism 26 is fixedly connected to screening mechanism 8, and eccentric mechanism 26 is drivenly connected to intermediate shaft 25. By setting eccentric mechanism 26 on intermediate shaft 25, the power on intermediate shaft 25 can be transmitted to eccentric mechanism 26. Through the fixed connection between eccentric mechanism 26 and screening mechanism 8, the power transmitted by intermediate shaft 25 is then transmitted to screening mechanism 8 by eccentric mechanism 26. Screening mechanism 8 realizes screening action through the movable connection of auxiliary mechanism and the power of eccentric mechanism 26, thereby completing the screening of peanut kernels and unshelled peanuts.

[0050] In this embodiment, peanuts enter the first shelling mechanism 5 through the first inlet 501 for the first shelling. After passing through the first shelling mechanism 5, the peanuts are separated into peanut kernels, peanut shells, and unshelled peanuts. The peanut shells are blown to the outside through the third outlet 19 by the air separation mechanism 7. The peanut kernels and unshelled peanuts fall to the screening mechanism 8. The screening mechanism 8 screens the peanut kernels into the first screening mechanism 801, and the unshelled peanuts into the second screening mechanism 802. The unshelled peanuts pass through the second screening mechanism 802. Peanuts smaller than the required size are screened out. Peanuts requiring a second shelling are conveyed by conveyor 22 to pneumatic conveyor 9, and then conveyed by pneumatic conveyor 9 to the second shelling mechanism 6 for a second shelling. After shelling, the peanut shells are blown out again by air separation mechanism 7, and the peanut kernels fall into screening mechanism 8. Screening mechanism 8 screens the peanut kernels into the first screening mechanism 801. The peanut kernels are then screened by the first screening mechanism 801, and peanut kernels smaller than the required size flow out. The remaining peanut kernels will flow out with the slide of the first screening mechanism 801.

[0051] The shelling device and peanut shelling machine of this embodiment use a detachable rubber sheet as the extrusion plate 203. When extruding peanuts, the degree of contact with the peanut is much lower than that of materials such as metal. Furthermore, the rubber sheet can buffer the extrusion force through its own elastic deformation, thereby reducing the damage of peanut kernels during the shelling process. The detachable design makes it very convenient to replace the rubber sheet. When the rubber sheet is worn, aged, or damaged, the operator can easily remove it and replace it with a new rubber sheet. Unlike the welded extrusion plate 203, it does not require complicated operations such as disassembling the entire component or re-welding. This can effectively reduce the equipment's maintenance time and maintenance costs.
