[0035] The present application will be described in detail below in conjunction with the drawings and examples.

[0036] ​​Example 1: A peanut dry peeling machine of the present invention includes a frame 2 and a peeling device 3, a feeding device 6, a power device 1, a discharge device 5, a peanut red skin suction device 7, and a clean peanut kernel recovery device 8 placed on the frame 2. The peeling device 3 includes a peeling cylinder 38, a peeling shaft 31, and multiple peeling rollers 34. Multiple peeling rollers 34 are arranged around the outer periphery of the peeling shaft 31 inside the peeling cylinder. In this example, eight peeling rollers 34 are used. A peanut peeling chamber is formed between the inner wall of the peeling cylinder 38 and the outer wall of the peeling rollers 34. The peeling rollers 34 and one end of the peeling shaft 31 are connected by a drive. The other end is connected to the power unit 1. A feed inlet 381 is opened on the upper side of the peeling tube 38. The feeding device 6 is placed on the side of the feed inlet 381 of the peeling device 3. The feeding inclined plate 62 is connected to the feed inlet 381 of the peeling tube of the peeling device 3. The discharge outlet 382 of the peeling tube is opened below the peeling tube 38. The discharge device 5 is correspondingly set on the frame 2 below the peeling tube 38. A clean peanut kernel recycling device 8 is set below the discharge device 5. A peanut red skin suction outlet 383 is opened between the feed inlet 381 and the discharge outlet 382 of the peeling tube, and a peanut red skin suction device 7 is connected to it.

[0037] The stripping device 3 also includes a fixed disk I 33, a fixed disk II 36, a gear I 37, and a gear II 4. The two ends of the stripping roller 34's shaft 35 are connected to the fixed disk I 33 and the fixed disk II 36 respectively, and pass through the fixed disk I 33 and the fixed disk II 36 respectively. One end of the roller shaft 35 closest to the power device 1 is connected to a shaft end retaining ring 32, and the other end, extending out of the fixed disk II 36, is equipped with a gear I 33. A gear shaft 42 is installed on the stripping shaft 31 at this end, and a gear II 4 is installed on it. Multiple gears I 33 are placed on gear II 4. The outer periphery meshes with it to ensure that gear II4 serves as the rotation track for gear I37. The two ends of the stripping cylinder 38 are respectively fixed to the frame 2 with left end cover 22 and right end cover 21. Gear I33, gear II4 and gear shaft 42 are all placed inside the left end cover 22. The shaft end retaining ring 32 and the stripping shaft 31 extending out of the fixed plate I33 are all placed inside the right end cover 22. The stripping shaft 31 extending out of the right end cover 21 is equipped with the transmission pulley II15 of the power device 1. The setting of the left and right end covers 22 and 21 serves to protect the stripping roller 34.

[0038] The power unit 1 comprises a motor 11, pulley I 13, pulley II 15, and a transmission belt 14. Pulley I 13 and pulley II 15 are respectively mounted on the motor output shaft 12 and the peeling shaft 31, and the transmission belt 14 is sleeved on pulley I 13 and pulley II 15. Driven by the motor 11, the transmission belt 14 and the peeling shaft 31 connected to pulley II 15 are rotated, which in turn drives the gear II 4 on it and the gear I 37 meshing with it to rotate, thereby driving the peeling roller 34 to rotate relative to the peeling cylinder 38. The peeling roller 34 rotates in the same direction as the peeling shaft 31, thus removing the red skin of the peanuts.

[0039] like Figure 2As shown, the distance between the outer circumferential surfaces of two adjacent stripping rollers 34 is 1-2 mm, and in this example, 2 mm. The distance between the inner circumferential surface of the stripping cylinder 38 and the outer circumferential surface of the stripping roller 34 is 1-2 mm, and in this example, 1 mm. The discharge port 382 formed in the stripping cylinder 38 is composed of a plurality of parallel grid strips, the width of the grid strips is 3-5 mm, and in this example, the width of the grid strips is 5 mm. According to the size of the peanut kernels to be stripped, the distance between adjacent grid strips is 15-30 mm, and in this example, the distance is 15 mm. The material of the stripping roller 34 is butadiene rubber. The roughness of the inner surface of the stripping cylinder is Ra50 or Ra25.

[0040] The suction device 7 includes a suction connector 71, a suction fan 73, and a connecting pipe 74. The cross section of the suction connector 71 is a convex structure, the small end of the convex structure is matched with the stripping cylinder suction port 383 and extends into the peanut red skin discharge port 383, and the other end is connected to the suction fan 73 through the connecting pipe 74. A filter screen 72 is arranged at the air suction port of the suction fan 73. The suction connector 71 is connected to the stripping cylinder 38 by screws, which is convenient for disassembly. The suction device 7 of the present application can fully absorb the peanut red skin inside the stripping chamber.

[0041] As shown in the drawings, Figure 6 The feeding device 6 is composed of a plurality of sheet metal parts welded together. A feeding hopper 64 is arranged on the top of a feeding frame 63. The bottom plate of the feeding hopper 64 is a feeding inclined plate 62. The feeding inclined plate 62 and the two side plates of the feeding frame 63 form a slot-shaped feeding port 65 structure. The feeding port 65 extends into the feeding port 381 of the stripping cylinder 38, and the peanut kernels are accurately fed into the stripping chamber. The hopper plate arranged above the feeding inclined plate 62 is a pluggable feeding amount adjusting plate 61.

[0042] A plurality of clamping grooves are symmetrically formed at the two ends of the feeding amount adjusting plate 61. Two buckles matched with the clamping grooves are arranged on the two side plates of the feeding hopper. The feeding amount is adjusted by adjusting the mounting clamping grooves of the feeding amount adjusting plate 61.

[0043] The discharge device 5 is an inverted conical outflow bin 51 arranged below the discharge port 382 of the stripping cylinder. The outflow bin 51 is fixed to the rack 2 by bolts, which is convenient for disassembly. A foreign matter removing fan 52 is arranged at one side of the bottom bin opening of the outflow bin 51. The peanut red skin discharged from the discharge port 382 is separated from the clean peanut kernels by the foreign matter removing fan 52. The two ends of the recycling basket 82 arranged below the bottom bin opening are provided with hanging ears, which are hung on the supporting rods arranged below the rack 2. The recycled clean peanut kernels are conveniently collected, and the stability of the recycling basket 82 is ensured.

[0044] In operation, peanut kernels pre-treated by dry processing enter the peeling chamber formed by the peeling cylinder 38 and peeling roller 34 through the feeding device 6. The peeling roller 34 rotates simultaneously with the peeling shaft 31, subjecting the peanut kernels to friction and compression, thus separating the red skin from the clean peanut kernels. Part of the detached red skin remains in the peeling chamber, while some adheres to the clean peanut kernels. The red skin adhering to the clean peanut kernels is discharged from the outlet 382 of the peeling cylinder 38 along with the peanut kernels. During the descent, the impurity removal fan 52 blows out and collects the red skin, while the clean peanut kernels fall into the collection frame 82 of the collection device 8. The red skin remaining in the peeling chamber is sucked out and collected by the suction device 7; this completes one working cycle of the peanut dry peeling machine.

[0045] Example 2: As Figure 2 As shown, in this example, the distance between the outer surfaces of two adjacent peeling rollers 34 is 1 mm. The distance between the inner surface of the peeling cylinder 38 and the outer surface of the peeling rollers 34 is 1.5 mm. The width of the grid bars of the discharge port 382 on the peeling cylinder 38 is 3 mm, and the distance between adjacent grid bars is 30 mm, depending on the size of the peanut kernels to be peeled.

[0046] Example 3: As Figure 2 As shown, the distance between the outer surfaces of two adjacent peeling rollers 34 in this example is 1.5 mm. The distance between the inner surface of the peeling cylinder 38 and the outer surface of the peeling rollers 34 is 2 mm. The width of the grid bars of the discharge port 382 on the peeling cylinder 38 is 4 mm, and the distance between adjacent grid bars is 20 mm, depending on the size of the peanut kernels to be peeled.
