Abstract
Description
Technical Field
[0001] This utility model relates to the field of nut processing technology, specifically to a nut peeling device. Background Technology
[0002] After nuts mature, they develop a green husk on their surface, which needs to be removed to obtain the nuts. Current nut peeling devices typically work by squeezing the fruit to break the nut husk and separate it from the nut. However, even after the husk is broken, it is not completely separated from the nut. There are still fibrous connections between the husk and the nut, causing the husk to stick to the nut. This requires manual peeling, which increases labor costs and reduces the efficiency of nut peeling. Utility Model Content
[0003] In order to overcome the problems existing in the background technology, the present invention provides a nut peeling device to solve the technical problem that after the current nut peeling device in the background technology peels the nut, there are still peel fibers connecting the peel and the nut, which causes the peel to stick to the nut. The peel needs to be peeled off manually, which increases labor costs and reduces the efficiency of nut peeling.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A nut peeling device includes a housing 1, a pressing mechanism 2, and a peeling mechanism 3. The pressing mechanism 2 and the peeling mechanism 3 are installed inside the housing 1, and the discharge end of the pressing mechanism 2 is connected to the feed end of the peeling mechanism 3. The peeling mechanism 3 includes a fixed cylinder 31, a drum screen 32, a stirring rod 33, and a motor I 34. The fixed cylinder 31 is fixedly installed inside the housing 1, and the drum screen 32 is rotatably installed inside the fixed cylinder 31. The drum screen 32 is rotatably installed in an annular groove provided on the inner wall of the fixed cylinder 31 via annular slide rails provided at both ends. The fixed cylinder 31 and the drum screen 32 are inclinedly arranged in the housing 1. The stirring rod 33 is evenly arranged on the inner wall of the drum screen 32. The end of the drum screen 32 is provided with a funnel-shaped feed inlet that connects to the discharge end of the pressing mechanism 2. The side wall of the feed inlet is provided with an annular groove for belt connection. The annular groove is connected to the motor I 34 installed at the bottom of the housing 1 via a belt, driving the drum screen 32 to rotate in the fixed cylinder 31.
[0006] Preferably, the pressing mechanism 2 includes a pressing cylinder 21 and an arc-shaped pressing groove 22. The pressing cylinder 21 is rotatably mounted on the inner wall of the housing 1 and is connected to a motor II 23 mounted on the outer wall of the housing 1. The arc-shaped pressing groove 22 is fixedly mounted on both sides of the inner wall of the housing 1. The upper and lower ends of the arc-shaped pressing groove 22 extend arc-shapedly from the bottom of the pressing cylinder 21 to the side of the pressing cylinder 21. Press rollers I 24 are evenly rotatably mounted on the outer wall of the pressing cylinder 21. Arc-shaped pressing rollers II 25 are installed at the bottom of the arc-shaped pressing groove 22. The distance between the arc-shaped pressing rollers II 25 and the pressing rollers I 24 gradually decreases from top to bottom. A feeding hopper 4 for feeding nuts into the housing 1 is installed at the top of the housing 1. The feeding hopper 4 is connected between the upper end of the arc-shaped pressing groove 22 and the pressing cylinder 21. A spout structure with a spout extending into the feed inlet of the drum screen 32 is provided at the lower end of the arc-shaped pressing groove 22.
[0007] Preferably, conical protrusions 26 are uniformly provided on the pressure rollers I 24 and II 25.
[0008] Preferably, the bottom of the fixed cylinder 31 is provided with a discharge window 311 to facilitate the leakage of fruit peel.
[0009] Preferably, the bottom of the casing 1 is provided with discharge hoppers 5 located below the arc-shaped pressure groove 22 and below the drum screen 32, respectively, to facilitate the discharge of fruit peels.
[0010] Preferably, the end of the housing 1 is provided with a nut discharge port 6 that connects with the discharge end of the drum screen 32 to facilitate the discharge of nuts.
[0011] The beneficial effects of this utility model are as follows: This utility model, through its pressing and peeling mechanisms, first uses the pressing mechanism to press open the nut shells, and then the peeling mechanism, with its rotating drum screen and continuously agitating rods, strikes and crushes the pressed-open nuts, thus separating the shells from the nuts. The crushed shells leak downwards through the sieve holes of the drum screen, thus separating them. The drum screen's crushing and striking action ensures the shells are completely removed from the nuts, avoiding the situation in traditional peeling machines where the shells are merely pressed open while still attached to the nuts. This device eliminates the need for manual peeling, saving manpower and improving the efficiency of nut peeling. Attached Figure Description

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0020] like Figure 1-7 As shown, this utility model provides a nut peeling device, including a housing 1, a pressing mechanism 2, and a peeling mechanism 3. The pressing mechanism 2 and the peeling mechanism 3 are installed inside the housing 1, and the discharge end of the pressing mechanism 2 is connected to the feed end of the peeling mechanism 3. The peeling mechanism 3 includes a fixed cylinder 31, a drum screen 32, a stirring rod 33, and a motor I 34. The fixed cylinder 31 is fixedly installed inside the housing 1, and the drum screen 32 is rotatably installed in the fixed cylinder 31. The drum screen 32 is rotatably installed in an annular groove provided on the inner wall of the fixed cylinder 31 through annular slide rails provided at both ends. The fixed cylinder 31 and the drum screen 32 are inclinedly arranged in the housing 1. The stirring rod 33 is evenly arranged on the inner wall of the drum screen 32. The end of the drum screen 32 is provided with a funnel-shaped feed inlet that connects to the discharge end of the pressing mechanism 2. The side wall of the feed inlet is provided with an annular groove for belt connection. The annular groove is connected to the motor I 34 installed at the bottom of the housing 1 through a belt, driving the drum screen 32 to rotate in the fixed cylinder 31. During peeling, the nuts are fed into the pressing mechanism 2 in the machine housing 1 to squeeze the peel open, and then fed into the peeling mechanism 3. The motor 1 34 drives the drum screen 32 to rotate in the fixed cylinder 31 via belt drive. The stirring rod 33 set on the inner wall of the drum screen 32 beats and crushes the nuts with the peel opened, so that the peel still attached to the nuts is completely removed. The crushed peel leaks down through the screen holes of the drum screen 32 and is separated. The drum screen 32 crushes and beats the nuts with the peel opened, so that the peel is completely removed from the nuts. This avoids the situation in traditional peeling machines where the peel is only pressed open while the peel is still attached to the nuts. This device does not require manual peeling, saving manpower and improving the efficiency of nut peeling.
[0021] The pressing mechanism 2 includes a pressing cylinder 21 and an arc-shaped pressing groove 22. The pressing cylinder 21 is rotatably mounted on the inner wall of the housing 1 and is connected to a motor II 23 mounted on the outer wall of the housing 1. The arc-shaped pressing groove 22 is fixedly mounted on both sides of the inner wall of the housing 1. The upper and lower ends of the arc-shaped pressing groove 22 extend arc-shapedly from the bottom of the pressing cylinder 21 to the side of the pressing cylinder 21. Press rollers I 24 are evenly rotatably mounted on the outer wall of the pressing cylinder 21. Arc-shaped pressing rollers II 25 are installed at the bottom of the arc-shaped pressing groove 22. The distance between the arc-shaped pressing rollers II 25 and the pressing rollers I 24 gradually decreases from top to bottom. A feeding hopper 4 for feeding nuts into the housing 1 is installed at the top of the housing 1. The feeding hopper 4 is connected between the upper end of the arc-shaped pressing groove 22 and the pressing cylinder 21. The lower end of the arc-shaped pressing groove 22 is provided with a spout structure that extends into the feed inlet of the drum screen 32. Nuts are fed from the feed hopper 4 on the machine casing 1 into the space between the pressure cylinder 21 and the arc-shaped pressure groove 22. The motor II 23 drives the pressure cylinder 21 to rotate, causing the pressure rollers I 24 and II 25 to squeeze the nuts, thereby breaking open the shells and separating the nuts from the shells. Under the rotation of the pressure cylinder 21, the squeezed nuts enter the drum screen 32 from the discharge port for further separation of the shells. Through the setting of the pressure cylinder 21 and the arc-shaped distribution of the pressure rollers II 25, the distance between the pressure rollers II 25 and the pressure rollers I 24 gradually decreases from top to bottom, which makes it easy to feed nuts from the top between the pressure rollers I 24 and the pressure rollers II 25. As the pressure cylinder 21 rotates, the nuts gradually fall into the position where the distance between the pressure rollers I 24 and the pressure rollers II 25 is smaller at the bottom. The pressure rollers I 24 and the pressure rollers II 25 squeeze the nuts, thereby breaking open the shells. This structure is simple in principle and ingenious in design, which facilitates the feeding of nuts and can easily and efficiently squeeze the nuts open, thereby improving the efficiency of nut peeling.
[0022] The pressure rollers I 24 and II 25 are uniformly provided with conical protrusions 26. When the pressure rollers I 24 and II 25 squeeze the nuts, the conical protrusions 26 insert into the peel, which is more conducive to squeezing and pressing the peel open, avoiding the situation where the peel is not pressed open, and improving the success rate of peeling nuts.
[0023] The bottom of the fixed cylinder 31 is provided with a discharge window 311 to facilitate the discharge of fruit peels. The fruit peels that are crushed in the drum screen 32 leak out through the discharge window 311, making it easy for the fruit peels to be discharged.
[0024] The bottom of the casing 1 is provided with discharge hoppers 5, located below the arc-shaped pressure groove 22 and below the drum screen 32, respectively, to facilitate the discharge of fruit peels. Fruit peels that leak from the gap of the pressure roller II 25 and fruit peels that leak from the drum screen 32 are discharged from the discharge hoppers 5.
[0025] The end of the casing 1 is provided with a nut discharge port 6 that connects with the discharge end of the drum screen 32 to facilitate the discharge of nuts.
[0026] Work process:
[0027] During peeling, nuts are fed from the feed hopper 4 on the machine housing 1 into the space between the pressure cylinder 21 and the arc-shaped pressure groove 22. The motor II 23 drives the pressure cylinder 21 to rotate, causing the pressure rollers I 24 and II 25 to squeeze the nuts, thereby pressing open the peel and separating the nuts from the peel. Under the rotation of the pressure cylinder 21, the pressed nuts enter the drum screen 32 from the discharge port for further peel separation. The drum screen 32 is driven by the belt drive of the motor I 34 to rotate in the fixed cylinder 31, causing the stirring rods 33 set on the inner wall of the drum screen 32 to beat and crush the nuts with the peeled peel, thereby completely removing the peel still attached to the nuts. The crushed peel leaks downward from the screen holes of the drum screen 32 and is separated. The drum screen 32 crushes and beats the nuts with the peeled peel, making the peel completely detach from the nuts. The peeled nuts are discharged from the nut discharge port 6.
[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
