Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a walnut peeling and screening mechanism. Background Art

[0002] Walnut is a common nut. Not only is its kernel nutritious, but its outer skin also has unique medicinal value. Walnut skin tastes bitter and spicy, and is warm in nature. It can soothe the liver and relieve qi, eliminate accumulation and relieve stagnation. There are many folk recipes for using walnut skin to treat various diseases. After the walnut is ripe, whether the outer green skin is peeled and cleaned is one of the indicators that determine the quality of the walnut.

[0003] In the process of walnut peeling, the green skin needs to be broken and peeled off manually to facilitate the subsequent processing of the walnuts. In actual work, the existing manual technology can basically meet the peeling and screening of walnut skins, but there are still the following two problems:

[0004] 1. The peeling effect of walnuts of uneven sizes is not good. Because it only peels the green skin of the walnut, and the peeling is not very thorough, it is necessary to further clean the surface of the walnut shell manually, which reduces the overall efficiency of peeling the green skin;

[0005] 2. Moreover, during the green peel peeling process, if the green peel is stored together with the walnuts or the remaining green peel is not cleaned in time or is not cleaned thoroughly enough, it will mold on the walnut shell, causing black spots on the walnuts, seriously affecting the quality of the walnuts.

[0006] To this end, the present application provides a walnut peeling and screening mechanism. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and provide a walnut peeling and screening mechanism.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a walnut peeling and screening mechanism, comprising a supporting frame, a peeling component is arranged on the supporting frame, the peeling component comprises an outer shell, the outer shell is penetrated and connected with a feed port, a second rotating shaft is arranged in the feed port, a pressure wheel is sleeved on the second rotating shaft, one end of the second rotating shaft penetrates the peeling component and is fixedly connected with the second gear and a nut, one end of the second rotating shaft is away from the second gear and is movably connected with the other end of the peeling component, a first gear is arranged on the outer wall of one end of the peeling component close to the second gear, a first rotating shaft is penetrated by the first gear, one end of the first rotating shaft is movably connected with the peeling component, and the other end of the first rotating shaft is fixedly connected to the output end of the motor.

[0009] As a preferred embodiment, a screening assembly is arranged in the peeling assembly, and the screening assembly is arranged at an angle. The screening assembly includes a screen plate, and the screen plate is provided with screen holes. A scraper is arranged on the end of the screen holes close to the second gear, and a pull ring is fixedly connected to the scraper. A pull groove is arranged on the end of the screen plate away from the second gear, and a groove is arranged at the bottom end of the peeling assembly.

[0010] As a preferred embodiment, a protective shell is provided in the peeling component, both ends of the protective shell are fixedly connected to the peeling component, a heating tube is fixedly connected in the protective shell, a cover plate is fixedly connected to the end of the peeling component close to the second gear, a flap is provided at the end of the peeling component away from the cover plate, the flap is movably connected to the peeling component through a third rotating shaft, and a limiting block is movably connected to the flap.

[0011] The technical effect of adopting the above further scheme is: heating the water in the peeling component to a certain temperature through the heating conduit, so that the kernel expands, the peeling efficiency is improved, the peeling effect is improved, the integrity of the walnut kernel is maintained, and the flavor of the final product is enhanced.

[0012] As a preferred embodiment, a water filling assembly is provided on one end of the support frame, and the water filling assembly includes a water tank, and a water pump is provided on the water tank, and the water pump is fixedly connected to the water tank through a fixing seat and bolts, and a water inlet pipe is penetrated and connected to the end of the water pump away from the cover plate, and the other end of the water inlet pipe is penetrated and connected to the water tank, and a water outlet pipe is penetrated and connected to the end of the water pump close to the second gear, and the other end of the water outlet pipe penetrates the peeling assembly and is fixedly connected to the peeling assembly, and the water outlet pipe is fixedly connected to a nozzle in the peeling assembly, and a storage box is provided at the bottom end of the peeling assembly, and the storage box is arranged on the support frame, and drainage outlets are respectively provided at both ends of the storage box.

[0013] The technical effect of adopting the above further scheme is: during the peeling process, since the walnut skin is relatively hard and difficult to handle in a dry state, the water stored in the water tank is pumped out by a water pump, and the water is transported to the peeling component through the outlet pipe and the nozzle to participate in the walnut peeling process, so that the water can penetrate into the gap between the walnut green skin and the shell, and the green skin is easier to be peeled off through the lubricating effect of water. At the same time, the presence of water can slow down the direct friction during the mechanical peeling process, thereby avoiding damage to the walnut kernel, thereby achieving the purpose of improving the peeling efficiency, reducing the walnut damage rate, reducing pollution and improving the freshness of the walnut.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are

[0015] 1. By setting up a peeling component, pour the walnuts to be peeled into the peeling component through the feed port, turn on the motor, and because the gaps of the first gear and the second gear intersect, the motor drives the first gear and the second gear to start rotating. At this time, the second rotating shaft, the pressure wheel and the protective shell in the peeling component rotate synchronously, and the diameter of the pressure wheel in the peeling component increases with the decrease in height, so that walnuts of different sizes can be fully squeezed between the protective shell and the pressure wheel to make the walnut skin fall off, thereby realizing the peeling process of the walnuts.

[0016] 2. By setting up the screening component, the shortest distance between the largest pressure wheel and the protective shell is smaller than the average minimum size of the walnut. At this time, the peeled skin after being fully squeezed falls down onto the screen plate due to gravity. Since the size of the sieve holes on the screen plate is larger than the size of the peeled skin, the peeled skin passes through the screen plate and falls into the storage box set at the lower end of the screen plate, while the peeled walnuts are discharged to the other half of the storage box through the flap for storage, thereby realizing the screening process of walnut peeling, improving the peeling efficiency, ensuring the peeling quality, reducing the damage rate and enhancing the market competitiveness.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 4 As shown, this embodiment provides a technical solution: a solar panel protective cover, including a support frame 1, a peeling component 2 is arranged on the support frame 1, the peeling component 2 includes a shell 21, the shell 21 is penetrated and connected with a feed port 22, a second rotating shaft 28 is arranged in the feed port 22, a pressing wheel 210 is sleeved on the second rotating shaft 28, one end of the second rotating shaft 28 penetrates the peeling component 2 and is fixedly connected with a second gear 27 and a nut 29, the second rotating shaft 28 is away from the second gear 27 and is movably connected with the other end of the peeling component 2, a first gear 25 is arranged on the outer wall of the peeling component 2 close to the second gear 27, a first rotating shaft 24 is penetrated by the first gear 25, and a first rotating shaft 24 is arranged on the outer wall of the first gear 25. The first end of the first rotating shaft 24 is movably connected to the peeling component 2, and the other end of the first rotating shaft 24 is fixedly connected to the output end of the motor 26. The walnuts to be peeled are poured into the peeling component 2 through the feed port 22, and the motor 26 is turned on. Because the gaps of the first gear 25 and the second gear 27 intersect, the motor 26 drives the first gear 25 and the second gear 27 to start rotating. At this time, the second rotating shaft 28, the pressure wheel 210 and the protective shell 211 in the peeling component 2 rotate synchronously, and the diameter of the pressure wheel 210 in the peeling component 2 gradually increases with the decrease in height, so that walnuts of different sizes can be fully squeezed between the protective shell 211 and the pressure wheel 210 to make the walnut skin fall off, thereby realizing the peeling process of the walnuts.

[0029] Further, such as Figure 3-Figure 4 As shown: a screening component 4 is arranged in the peeling component 2, and the screening component 4 is arranged at an angle. The screening component 4 includes a screen plate 41, and a screen hole 42 is opened on the screen plate 41. A scraper 43 is arranged on the end of the screen hole 42 close to the second gear 27, and a pull ring 45 is fixedly connected to the scraper 43. A pull groove 44 is opened on the end of the screen plate 41 away from the second gear 27, and a groove is opened at the bottom end of the peeling component 2.

[0030] The above solutions still have the problem of how to enhance the peeling efficiency of the device, such as Figure 3As shown: In the present embodiment, a protective shell 211 is provided in the peeling component 2, and both ends of the protective shell 211 are fixedly connected to the peeling component 2, a heating tube 212 is fixedly connected in the protective shell 211, and a cover plate 23 is fixedly connected to the end of the peeling component 2 close to the second gear 27, and a flap 214 is provided at the end of the peeling component 2 away from the cover plate 23. The flap 214 is movably connected to the peeling component 2 through a third rotating shaft 213, and a limited block 215 is movably connected on the flap 214. The water in the peeling component 2 is heated to a certain temperature through the heating tube 212, so that the kernel expands, thereby improving the peeling efficiency, improving the peeling effect, maintaining the integrity of the walnut kernel, and enhancing the flavor of the final product.

[0031] The above solutions still have the problem of how to enhance the peeling efficiency of the device, such as Figure 1 as well as Figure 3 As shown: In this scheme, a water filling component 3 is arranged at one end of the support frame 1, and the water filling component 3 includes a water tank 31, and a water pump 33 is arranged on the water tank 31. The water pump 33 is fixedly connected to the water tank 31 through a fixing seat 32 and a bolt 36. The end of the water pump 33 away from the cover plate 23 is penetrated and connected with a water inlet pipe 35, and the other end of the water inlet pipe 35 is penetrated and connected with the water tank 31. The end of the water pump 33 close to the second gear 27 is penetrated and connected with a water outlet pipe 34, and the other end of the water outlet pipe 34 penetrates the peeling component 2 and is fixedly connected to the peeling component 2. The water outlet pipe 34 is fixedly connected with a nozzle 37 in the peeling component 2. The bottom end of the peeling component 2 is provided with a storage box 5, and the storage box 5 is arranged on the support frame 1. On the support frame 1, drainage outlets 6 are respectively provided at both ends of the storage box 5. During the peeling process, since the walnut skin is hard and difficult to handle in a dry state, the water stored in the water tank 31 is pumped out by a water pump 33, and the water is transported to the peeling component 2 through the outlet pipe 34 and the nozzle 37 to participate in the walnut peeling process, so that the water can penetrate into the gap between the walnut green skin and the shell. The green skin is easier to be peeled off through the lubricating effect of water. At the same time, the presence of water can slow down the direct friction during the mechanical peeling process, thereby avoiding damage to the walnut kernel, thereby achieving the purpose of improving the peeling efficiency, reducing the walnut damage rate, reducing pollution and improving the freshness of the walnut.

[0032] Working principle:

[0033] like Figure 1-4 As shown:

[0034] When in use: pour the walnuts to be peeled into the peeling assembly 2 through the feed port 22, turn on the motor 26, and because the first gear 25 and the second gear 27 have gaps intersecting, the motor 26 drives the first gear 25 and the second gear 27 to start rotating. At this time, the second rotating shaft 28, the pressing wheel 210 and the protective shell 211 in the peeling assembly 2 rotate synchronously, and the diameter of the pressing wheel 210 in the peeling assembly 2 increases as the height decreases, so that walnuts of different sizes can be peeled by the gap between the protective shell 211 and the pressing wheel 210. The walnut skin is fully squeezed to fall off, and the walnut peeling process is completed. The shortest distance between the largest pressing wheel 210 and the protective shell 211 is smaller than the average minimum size of the walnut. At this time, the peeled skin that is fully squeezed falls down on the screen plate 41 under the action of gravity. Since the size of the sieve holes 42 opened on the screen plate 41 is larger than the size of the peeled skin, the peeled skin passes through the screen plate 41 and falls into the storage box 5 set at the lower end of the screen plate 41. The residue remaining on the screen plate 41 can be pushed out by pulling the pull ring 45, realizing Manual cleaning can prevent the sieve hole 42 from being blocked due to excessive accumulation of residues on the sieve plate 41, resulting in a decrease in the working efficiency of the device. The peeled walnuts are discharged to the other half of the storage box 5 through the flap 214 for storage. During the peeling process, since the walnut skin is hard and difficult to handle in a dry state, the water stored in the water storage tank 31 is pumped out by the water pump 33, and the water is transported to the peeling component 2 through the outlet pipe 34 and the nozzle 37 to participate in the walnut peeling process, so that the water can penetrate into the gap between the walnut green skin and the shell. The green skin is easier to be peeled off through the lubricating effect of water. At the same time, the presence of water can slow down the direct friction during the mechanical peeling process, thereby avoiding damage to the walnut kernel, thereby achieving the purpose of improving the peeling efficiency, reducing the walnut damage rate, reducing pollution and improving the freshness of the walnut. The water in the peeling component 2 is heated to a certain temperature by the heating conduit 212, so that the kernel expands, the peeling efficiency is improved, the peeling effect is improved, the integrity of the walnut kernel is maintained and the flavor of the final product is enhanced.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
