Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural processing machinery, and particularly relates to a wet peanut red coat removing machine. BACKGROUND

[0002] Peanut is not only an important crop, but also can provide a variety of nutrients, which is very beneficial to human health. The peanut kernel, peanut red coat and the like have high economic processing value. Peanut red coat removing is an important link in the peanut processing process, and is crucial for producing peanut kernel products. At present, the peanut coat removing process in China has not reached an ideal level. Although mechanical coat removing can improve production efficiency, it can cause damage to the peanut kernel. The efficiency and universality of the coat removing machine need to be improved.

[0003] At present, an extrusion type wet peanut red coat removing machine is mostly used in China. The working principle of the machine is that the peanut kernel enters the coat removing device from the feeding port, rotates with the coat removing wheel, is cut at the highest point by the blade, and is extruded out of the cut by the extrusion wheel to obtain the peanut kernel. The peanut red coat continues to rotate with the rubber wheel and is finally thrown out by the skin removing wheel. Although the equipment has high net removal rate and working efficiency, the universality is poor, and the whole kernel rate needs to be improved. The radius of the pressing wheel of the pressing device of the existing wet peanut red coat removing machine is not adjustable. Therefore, for different types and sizes of peanuts, the position of the peanut pressed into the coat removing device is the same. Since the peanut enters from the outside of the coat removing wheel, when small size peanuts enter, the pressing position may be shallow, and the extrusion force is not enough, which causes the peanut kernel to not be removed from the peanut red coat smoothly, so that the net removal rate is low. When large size peanuts enter, the pressing position is deep, and the clamping force is large, so that the large peanuts are easily broken, and the breakage rate is high.

[0004] Therefore, optimizing and improving the peeling machine and improving its universality are of great significance for improving the quality of peanut products. SUMMARY

[0005] In view of the above technical problems, the present application provides a wet peanut red coat removing machine. It can improve the peanut coat removing net removal rate and reduce the breakage rate, and can realize the coat removing of different varieties of peanuts, and improves the universality of the coat removing machine.

[0045] The present application will be described in detail below with reference to the accompanying drawings and examples.

[0046] Example 1: As Figure 1As shown, this invention discloses a peanut wet skinning machine, comprising a frame 1 and a skinning device 3, a pressing device 10, a skinning device 6, an extrusion device 8, a skinning device 9, an anti-flying device 5, a feed inlet 4, a discharge outlet 7, a transmission device 2, and a power device 11 mounted on the frame 1. The skinning device 3 includes multiple skinning wheels 31 arranged in parallel and side plates on both sides. A feed inlet 4 and a discharge outlet 7 are respectively opened on one side plate, and the feed channel 41 and discharge channel 71, which are connected to the side plate, extend into the skinning wheels 31. The pressing device 10, the anti-flying device 5, and the peeling device 6 are arranged clockwise inside the stripping wheel 31, with the peeling device 6 at the top. The extrusion device 8 is installed above the outside of the stripping wheel 31, below the peeling device 6. The peeling cleaning device 9 is located below the extrusion device 8 outside the stripping wheel 31, with its upper cleaning wheel 91 extending into the gap between the stripping wheels 31. The feeding channel 41 is located below the anti-flying device 5, the discharging channel 71 is located below the extrusion device 8, and the pressing device 10 is located below the feeding channel 41, inside the stripping wheel 31. The gap is larger than the outer gap. The pressing wheel 102 of the pressing device 10, the cutter 61 of the peeling device 6, and the anti-flying wheel 51 of the anti-flying device 5 all correspond to the inner gap between the peeling wheels 31. The extrusion wheel 81 of the extrusion device 8 and the peeling wheel 91 of the peeling device 9 correspond to the outer gap between the peeling wheels 31. During operation, peanut kernels enter the peeling device 3 through the feed inlet 4. During this process, some peanut kernels may fall off along the peeling device 3. The fallen peanut kernels continue to enter the peeling wheel 3 under the pushing action of the pressing wheel 102. 1. Inside the gap, as the peeling wheel 31 rotates, when the peanut kernel reaches its highest point, the peanut skin is cut by the cutter 61. The peanut kernel continues to rotate with the peeling wheel 31. When it passes through the extrusion device 8, the clean peanut kernel is squeezed out from the peanut skin and falls into the collection device through the discharge port 7. The peanut skin left in the gap of the peeling wheel 31 rotates with the peeling wheel 31. When it passes through the peeling device 9, the peanut skin is thrown out of the machine under the relative motion of the peeling wheel 91 and the peeling wheel 31. This completes one working cycle of peanut peeling.

[0047] Furthermore, such as Figures 1-4 As shown, the stripping wheel 31 of the stripping device 3 is made of rubber and is externally tangential to the power wheel 111 in the power device 11, thereby achieving fixation. During operation, the power device 11 drives the stripping wheel 31 to rotate clockwise. The gap between adjacent stripping wheels 31 is a wedge shape that is narrower on the outside and wider on the inside. The minimum value L1 of the wedge-shaped gap is 4mm, the maximum value L2 is 24mm, and the thickness H of the stripping wheel is 28mm.

[0048] like Figure 4 As shown, the angle α between the wedge-shaped inclined surface of the stripping wheel 31 and the vertical direction is 20°.

[0049] like Figures 5-8As shown, the pressing device 10 comprises a pressing shaft 101, an adjusting shaft 106, a plurality of pressing wheel sets and a fixing disc 105, the pressing shaft 101 is fixed on the frame 1 through a bearing seat, the pressing shaft 101 and the adjusting shaft 106 are arranged side by side, the fixing disc 105 is fixedly connected on the pressing shaft 101 and sleeved on the adjusting shaft 106, so as to fix the positions of the pressing shaft 101 and the adjusting shaft 106, the plurality of pressing wheel sets are arranged side by side on the pressing shaft 101 and the adjusting shaft 106, each pressing wheel set comprises a pressing wheel 102, a large gear 103 and a small gear 104, the large gear 103 is sleeved on the pressing shaft 101 and is not fixed with the pressing shaft 101, the small gear 104 which is in meshing transmission with the large gear 103 is installed on the adjusting shaft 106 and rotates with the adjusting shaft 106; the pressing wheel 102 comprises a mounting disc 1013 concentrically arranged on the pressing shaft 101, an inner side diameter 1012, an outer side diameter 1011 and a rotating disc 1014, the inner side diameter 1012 and the outer side diameter 1011 are uniformly and circumferentially connected on the outer periphery of the rotating disc 1014 and are arranged between the mounting disc 1013 and the rotating disc 1014, the mounting disc 1013 is provided with an adjusting shaft mounting hole, a plurality of arc-shaped holes are uniformly and circumferentially spaced apart on the rotating disc 1014 and are connected with the corresponding inner side diameter 1012 and outer side diameter 1011 through connecting bolts, the large gear 103 is fixedly connected with the rotating disc 1014, by rotating the adjusting shaft 106, the small gear 104 is driven to rotate, and then the large gear 103 and the rotating disc 1014 are driven to rotate around the pressing shaft 101, the arc-shaped holes on the rotating disc 1014 are rotated, and the inner side diameter 1012 and the outer side diameter 1011 are synchronously moved along the arc-shaped holes on the rotating disc 1014 through the connecting bolts thereon, so as to adjust the radius of the pressing wheel 102.

[0050] The two ends of the inner side diameter 1012 are arranged inside the outer side diameter 1011 and are tangent to the inner ring of the outer side diameter 1011, and the rotating disc 1014 and the mounting disc 1013 are attached to the outer side diameter 1011 and the inner side diameter 1012.

[0051] The pressing depth of the pressing wheel 102 to the stripping wheel 31 is 13 mm, and the diameter of the pressing wheel 102 in this example is 113 mm. According to the size of the stripping wheel 31 of the stripping device 3, the distance between adjacent pressing wheels is matched with the stripping device, so that the pressing wheel can be smoothly pressed into the gap of the stripping device and the work can be smoothly carried out when the radius of the pressing wheel is adjusted, and the width W1 of the pressing wheel is 8 mm.

[0052] As Figure 9As shown, the skinning device 5 is provided with a plurality of cutters 61 on a guide rail 51 fixed on the frame 1, and the cutters 61 are connected to the guide rail 51 through springs 52, with the working ends of the cutters 61 extending into the gap of the stripping wheel 31 by 12 mm from the outer edge of the stripping wheel. To cooperate with the stripping device, the distance between adjacent cutters 61 is 35 mm. When small-sized peanuts pass through, the peanuts are clamped in a deep position due to the small size, and the position of the spring cutter 61 is high, so that the top end of the cutter 61 can just contact the peanuts when the small-sized peanuts pass through, and since the peanuts are pretreated, a relatively small force can make a cut, thereby achieving the subsequent stripping purpose; when large-sized peanuts pass through, the peanuts are clamped in a shallow position due to the large size, so that the spring cutter 61 will be compressed when the large-sized peanuts pass through, and at this time, the large peanuts can pass through and contact the cutter 61, thereby making a cut to complete the subsequent stripping. The working end of the cutter 61 in this example is a rhombus end, and the material is selected to be alloy steel, which has the advantages of high cutting efficiency, good cutting quality, long service life, convenient cutter replacement, and the like, and can improve processing efficiency, reduce cost, and improve product quality, etc. The spring 62 is selected to be low-carbon manganese steel, which has the advantages of low price, good hardenability, and high strength, and according to actual needs, the cutter spring 62 in this example.

[0053] As shown in Figure 10 The flying prevention device 5 includes a flying prevention shaft 52 and a plurality of flying prevention wheels 51 arranged side by side on the flying prevention shaft 52, and the number of the flying prevention wheels 51 is one less than the number of the stripping wheels 31, corresponding to the gaps of the adjacent stripping wheels 31, located above the feeding channel 41, and the flying prevention shaft 52 is installed on the frame 1 through a bearing seat. The function of the flying prevention device is to prevent peanuts from flying out during the operation of the stripping device 3. The material of the flying prevention wheel 51 is selected to be alloy steel material with wear resistance and corrosion resistance, which is safe and reliable and does not need to be frequently disassembled. The structure of the flying prevention wheel 51 is a pair of symmetrical circular truncated cone structures on both sides of the disc, and the outer diameter of the disc is larger than the outer diameters of the two sides of the circular truncated cone, and the gap between the flying prevention wheel 51 and the stripping wheel 31 is matched. In this example, the outermost diameter of the flying prevention wheel 51 is 120 mm, the inner diameter is 70 mm, the width W2 of each flying prevention wheel 51 is 28 mm, and the distance between the adjacent two flying prevention wheels 51 is 4 mm, which cooperates with the stripping wheel 31 in this example. The flying prevention wheel 51 is rotated around the flying prevention shaft 52 driven by the stripping wheel 31, which can fully prevent the peanuts from flying out during rotation and improve the stripping efficiency of the stripping machine.

[0054] Further, as shown in Figures 1-3As shown, the extrusion device 8 includes an extrusion shaft 82 and a plurality of extrusion wheels 81 arranged side by side on the extrusion shaft 82, in this example, three extrusion wheels 81 are provided, which are in gap cooperation with the stripping wheels 31 and are located above the discharge channel 71 outside the stripping wheels 31. The extrusion shaft 82 is installed on the frame 1 through a bearing seat. The extrusion wheels 81 are made of a material with sufficient strength and wear resistance, such as alloy steel or hard plastic. The surface of the extrusion wheels 81 is sprayed, plated or heat treated to increase the friction and wear resistance.

[0055] The extrusion wheels 81 are flat discs, and a small gap of 1-2 mm is left between the two sides of the adjacent extrusion wheels 81 and the stripping wheels 31 to prevent power loss. In this example, the width of the extrusion wheels 81 is 3 mm, and the gap between the adjacent extrusion wheels 81 is 29 mm. The extrusion wheels 81 are pressed in with a depth that extends beyond the length of the inner side of the stripping wheels 31 to ensure that they can effectively strip the peanut skin.

[0056] Further, as shown in Figure 11 The skin removing device 9 includes a skin removing shaft 92 and a plurality of skin removing wheels 91 arranged side by side on the skin removing shaft 92, which are located below the extrusion device 8 outside the stripping wheels 31. In this example, the skin removing wheels 91 are three, which are in gap cooperation with the stripping wheels 31. The skin removing shaft 92 is installed on the frame 1 through a bearing seat, and a sprocket wheel II 26 is installed thereon, and the chain 28 of the power device is sleeved thereon. Its function is to remove the peanut red skin adhered in the gap of the stripping wheels 31. In this example, the skin removing wheels 91 are in the shape of a pentagram, the width W3 of the skin removing wheels 91 is 4 mm, and the distance L3 between the adjacent skin removing wheels 91 is 28 mm. The skin removing shaft 92 cooperates with the bearing seat 12. When the rotation direction of the skin removing wheels 91 is opposite to that of the stripping wheels 31, the peeling efficiency of the stripping machine can be greatly improved. The skin removing wheels 91 are made of a material with corrosion resistance and a small surface friction coefficient, such as alloy steel, aluminum alloy, etc. The surface of the skin removing wheels 91 is relatively smooth, which reduces the friction between the skin removing wheels 91 and the stripping wheels 31 and reduces the mechanical loss. The service life of the pentagram-shaped skin removing wheels 91 is long, and they can be repeatedly used for many times, which reduces the material and labor costs and also reduces the pollution to the environment.

[0057] As shown in Figures 1-3As shown, the power device 11 includes power wheel I 111, power wheel II 112 and its transmission shaft 113, wherein the power wheel I 111 is arranged above the frame 1 through its transmission shaft 113, and two power wheel II 112 are arranged below the frame 1 through its transmission shaft, forming a stable triangular structure and respectively tangential to the stripping wheel 31, and chain wheels I 25, chain wheels III 27 and chain wheels IV 29 are respectively installed on the transmission shaft, and each chain wheel is externally arranged with a chain 28, wherein the transmission shaft of one power wheel II 112 is connected with the transmission device 2, and the transmission device 2 includes a motor 22, a large pulley 24 and a small pulley 21, the large pulley 24 is installed on the transmission shaft of one power wheel II 112 and is in transmission connection with the small pulley 21 on the output shaft of the motor 22 through a belt. The power wheel I 111 is a roller shaft with two side edges, and the roller shaft is tangent to the outer edge of the stripping wheel 31; the power wheel II 112 is a plurality of round wheels arranged side by side on the roller shaft with two side edges (the number of round wheels is the same as the number of gaps of the stripping wheel 31), and each round wheel is in cooperation with a gap of the stripping wheel 31, and the width of each round wheel is 4 mm and the spacing between the round wheels is 28 mm. The material of the power wheel is an alloy material. Driven by the motor 22, the small pulley 21 and the large pulley 24 are rotated, thereby driving the transmission shaft on which the large pulley 24 is installed, the chain wheels and the power wheel II 112 to rotate, and the power wheel I 111 and the other power wheel II 112 are driven to rotate synchronously through the chain, thereby driving the stripping wheel 31 tangential to the power wheel to rotate.

[0058] Other parts of the present application all adopt existing structures, which will not be described herein.

[0059] In the working process of the present application, the pretreated peanut kernels are sent into the feeding channel 41 through the feeding port 4, and the peanut kernels gradually approach the stripping device 3 fixed by three power wheels rotating in the clockwise direction under the action of the vibration of the machine, and contact the stripping wheel 31, and then enter the gap of the stripping wheel 31 and rotate with the stripping wheel 31. Part of the peanut kernels falls off and enters the gap of the stripping wheel 31 under the pushing action of the pressing device 10 and continues to rotate with the stripping wheel 31. When the peanut kernels move to the highest point, a long opening with a depth of about 2-3 mm is cut by the skin cutting knife 61 of the skin cutting device 6, which opens the bolt for the clean peanut kernels to be stripped from the red skin, and the clean peanut kernels are pressed out from the red skin by the extrusion wheel 81 and thrown to the discharge channel 71, and then flow out to the container through the discharge port 7.
