Description

Technical Field

[0001] The utility model relates to the technical field of peanut processing, in particular to a peanut peeling machine. Background Art

[0002] A peanut peeling machine is a machine used to remove the outer shell of peanuts, which is widely used in fields such as food processing, agricultural production, and households. The working principle of the peanut peeling machine mainly relies on mechanical friction, impact, or rubbing, etc.

[0003] Reference can be made to the existing literature, an efficient peanut peeling machine (CN219939601U). In the reference, the first peeling roller and the second peeling roller are set to carry out preliminary peeling work on peanuts. The peanuts after preliminary peeling fall onto the top surface of the set vibrating plate, and then through the set vibrating motor, the peanuts are further vibrated and peeled, thereby increasing the peeling efficiency of the device for peanuts and realizing efficient peeling work.

[0004] The driving mode of the peeling roller in the above literature is to use an electric motor as the driving source, then drive a gear to rotate through a pulley structure, and then drive another gear meshing with it to rotate in the opposite direction. This is the traditional driving mode of peanut peeling machines on the market. This design will cause the distance between the two peeling rollers to be unable to be adjusted. Once adjusted, the two gears cannot mesh and thus cannot produce linkage. The peeling rollers with a fixed distance design are difficult to effectively adapt to peanuts of different sizes. For smaller peanuts, the matching degree is not high and it is easy to cause incomplete peeling. For larger peanuts, it is easy to cause extrusion and breakage of the peanuts. And in the above literature, the peanut skins are sucked into the collection box by wind power, and at the same time, dust and impurities will be sucked in. The peanut skins and dust and impurities are easily scattered in the collection box and are not convenient for centralized treatment. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a peanut peeling machine is proposed. The utility model drives two peeling roller assemblies to move in opposite directions through a peeling distance adjustment component, adjusts the distance between the peeling roller assemblies within a certain range, and can make corresponding adjustments according to the size of the peanuts before peeling, reducing the situations of incomplete peeling or peanut breakage. At the same time, the peanut skins and debris after wind sorting will be centrally collected into the water tank for subsequent treatment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0029] Refer to Figures 1-5, A peanut peeling machine, comprising: a peeling chamber 1, a peeling distance adjustment component is provided on the left side of the peeling chamber 1. The peeling distance adjustment component includes two sliders 15 that can move in opposite directions and can drive the peeling roller component connected thereto to move in the opposite direction for distance adjustment. The lower part of the peeling chamber 1 is connected to a wind separation chamber 5 through a feed hopper 4. A blower 7 and a water storage tank 6 are respectively installed at both ends of the wind separation chamber 5 through fixing plates. The air outlet of the blower 7 is connected to a first air duct 8. The wind separation chamber 5 and the water storage tank 6 are connected through a second air duct 11. Peanut skins are sent into the water storage tank 6 through the second air duct 11 for collection. Peanuts enter the peeling chamber 1 and are rubbed and peeled by the reverse rotation of two peeling roller components. The peeling distance adjustment component serves as the driving source for the two peeling roller components, and can drive the two peeling roller components to move and rotate in the opposite direction, replacing traditional transmission methods such as belt pulleys and gears. The peeling roller components move in the opposite direction for distance adjustment, and then can be adjusted accordingly according to the actual size of the peanuts to achieve a more matching distance for peeling operations. The peanuts and peanut skins after peeling treatment in the peeling chamber 1 will be concentrated and enter the wind separation chamber 5 through the feed hopper 4. By operating the blower 7 on one side of the wind separation chamber 5, pressurized gas is sent into the wind separation chamber 5 through the first air duct 8. The air outlet of the first air duct 8 is arranged inside the wind separation chamber 5, and the second air duct 11 is connected to the right side of the wind separation chamber 5, and its setting position is slightly higher than that of the first air duct 8, so that the lighter peanut skins float up and enter the second air duct 11 and are sent into the water storage tank 6, and then the dust and impurities that enter together with the peanut skins are concentrated in the water storage tank 6, effectively avoiding the scattered distribution of peanut skins and dust, and facilitating subsequent processing.

[0030] It is conceivable that multiple air outlets of the first air duct 8 can be equidistantly arranged to increase the blowing range.

[0031] Specifically, the peeling distance adjustment component mainly includes: a driving box 3, which is fixed to the peeling chamber 1 through two fixed brackets 12; a bidirectional screw 14, which is rotatably connected inside the driving box 3; an adjustment knob 13, which is connected to one end of the bidirectional screw 14 and is rotatably connected to one side of the driving box 3. Further, the peeling distance adjustment component further includes: two sliders 15 threadedly connected to the outside of the bidirectional screw 14. The thread directions of the two sliders 15 are the same and both are provided with installation grooves at one end; a driving motor 16, which is fixed inside the installation grooves. During the operation of the peeling distance adjustment component: First, rotate the adjustment knob 13 to drive the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 can cause the two sliders 15 threadedly connected to the outside to move in the opposite direction. The two sliders 15 are symmetrically distributed with respect to the central position of the bidirectional screw 14 and move within the stroke of the bidirectional screw 14. Installation grooves for installing the driving motor 16 are preset in both sliders 15. The driving motor 16 serves as the driving source for driving the peeling roller component to rotate. The driving motors 16 operate in opposite directions and can drive the two peeling roller components to rotate in the opposite direction to rub the peanuts.

[0032] In this embodiment, the peeling roller assembly includes: a peeling roller main body 17, which is provided with two inside the peeling chamber 1; a second connecting frame 25, which is fixed to both ends of the peeling roller main body 17; a connecting rod 24, which is connected to the other end of the second connecting frame 25, and one of the connecting rods 24 is directly fixed to the output end of the driving motor 16. During the peeling process, the peeling roller main body 17 plays a main rubbing role. After the driving motor 16 operates, it will drive the second connecting frame 25 and the peeling roller main body 17 integrated with it to rotate through the connecting rod 24.

[0033] Specifically, refer to Figure 4 , movable openings are provided on both the left and right sides of the peeling chamber 1. Two fixing blocks 19 are slidably arranged inside the movable openings. Slideways 18 are provided at both the upper and lower ends of the movable openings. Bearings 20 are installed inside the fixing blocks 19. The connecting rods 24 are fixed to the inner rings of the bearings 20. The upper and lower ends of the fixing blocks 19 are connected to first connecting frames 21 that can move inside the slideways 18. Both of the movable openings are square in design and their height matches that of the fixing blocks 19, ensuring the stability of the movement of the fixing blocks 19. The bearings 20 integrated inside the fixing blocks 19 are used to fix the connecting rods 24 in the peeling roller assembly. The cylindrical connecting rods 24 are fixed to the inner rings of the bearings 20, making the rotation of the connecting rods 24 smoother. During the reverse movement of the peeling roller assembly, the four fixing blocks 19 in the two movable openings all move inside the movable openings, and the first connecting frames 21 at the upper and lower ends of the fixing blocks 19 move inside the two slideways 18 in the movable openings. This design can not only support the peeling roller assembly but also ensure the stability of the rotation and displacement of the peeling roller assembly.

[0034] Furthermore, as Figure 4 shown, two baffles 22 are fixed inside the peeling chamber 1. Slideways 23 are provided on the baffles 22. The second connecting frames 25 move on the slideways 23. Since there are movable openings for the movement of the fixing blocks 19 on both the left and right sides of the peeling chamber 1, during the processing, the peanuts and debris inside are likely to float out from the movable openings at both ends. Therefore, two baffles 22 are installed inside the peeling chamber 1. The height of the baffles 22 matches the internal height of the peeling chamber 1, and only a slideway 23 for passing through the cylindrical second connecting frame 25 is left.

[0035] Above the peeling chamber 1, there is a feed hopper 2. Peanuts are poured in concentratedly through the feed hopper 2. Transparent observation windows are provided at both the front ends of the peeling chamber 1 and the water storage tank 6. The transparent observation windows facilitate observing the peeling situation inside the peeling chamber 1 and then adjusting the spacing of the peeling roller assembly. The transparent observation window on the water storage tank 6 facilitates observing the turbidity of the internal liquid for water source replacement.

[0036] The wind separation chamber 5 is arranged in a drawer type, which is convenient for centralized collection of the shelled peanuts. There is a water injection port above the water storage tank 6 and a drain pipe 9 with a valve 10 is connected below it. When changing the water source, open the valve 10 to make the mixture of peanut skins, debris, etc. concentrate and drain through the drain pipe 9, and then add a new water source through the water injection port.

[0037] Working principle: When using the present utility model, during the process of adjusting the distance between the peeling roller assemblies, first rotate the adjusting knob 13 to drive the rotation of the bidirectional screw 14. The rotation of the bidirectional screw 14 can make the two sliders 15 connected by external threads move in opposite directions. The two sliders 15 are symmetrically distributed around the central position of the bidirectional screw 14 and move within the stroke of the bidirectional screw 14. Installation grooves for installing the drive motors 16 are preset in both sliders 15. The drive motors 16 serve as the drive sources for driving the rotation of the peeling roller assemblies. The drive motors 16 operate in opposite directions and can drive the two peeling roller assemblies to rotate in opposite directions to rub the peanuts. The peanuts and peanut skins after the peeling treatment in the peeling chamber 1 will concentrate and enter the wind separation chamber 5 through the material guiding hopper 4. By operating the blower 7 on one side of the wind separation chamber 5, the pressurized gas is sent into the wind separation chamber 5 through the first air duct 8. The air outlet of the first air duct 8 is arranged inside the wind separation chamber 5. The second air duct 11 is connected to the right side of the wind separation chamber 5, and its installation position is slightly higher than that of the first air duct 8, so that the lighter peanut skins float up and enter the second air duct 11 and are sent into the water storage tank 6. Furthermore, the dust and impurities that enter together with the peanut skins are concentrated in the water storage tank 6, effectively avoiding the scattered distribution of peanut skins and dust, which is convenient for subsequent treatment.

[0038] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
