Abstract
Description
Technical Field
[0001] This utility model relates to a peanut shelling device, specifically a vertical umbrella-shaped multifunctional peanut shelling device. Background Technology
[0002] Traditional peanut shelling equipment typically uses a high-speed rotating machine body to break peanut shells through collision, crushing, and friction to separate peanut kernels from shells. However, crushing the outer shell can easily damage the inner peanut kernels. Incomplete peanut kernels affect peanut processing and yield. Therefore, all peanut shelling equipment manufacturers are committed to researching ways to reduce peanut kernel breakage during shelling. Peanut shelling equipment on the market is trying to find a balance between reducing the machine speed to reduce the breakage rate and improving shelling efficiency.
[0003] The structure of traditional horizontal peanut shelling equipment mainly includes: a drum frame, a horizontal drum screen mounted on the drum frame, a power main shaft located inside the drum screen, and a striking rod or crushing roller mounted on the power main shaft. The drum screen is equipped with screen holes with gaps. The peanuts entering the drum screen are centrifugally rotated inside the drum screen by the power main shaft and the crushing rod or crushing roller. The peanut shells are broken by collision, crushing and friction. Finally, the broken peanut kernels and peanut shells are discharged from the screen holes of the drum screen. However, the aforementioned structure utilizes centrifugal force and rotating crushing rods to crush peanut shells, resulting in the drum screen only working on the screen wall at its highest position, with poor crushing effect in other areas. Consequently, the overall work efficiency is not high. Furthermore, the enclosed structure of its horizontal drum causes the peanuts to be repeatedly crushed within the enclosed space during operation, leading to a high crushing rate. Increasing the crushing space in traditional shelling machines can result in incomplete shelling. Additionally, adjusting the crushing spacing according to the size of the peanuts is quite difficult with traditional horizontal peanut shelling equipment. This is because the power shaft and crushing structure of horizontal peanut shelling equipment cannot be adjusted in position; only the position of the horizontal drum screen can be adjusted. The large size of the horizontal drum screen makes position adjustment difficult and results in low precision. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a vertical umbrella-shaped multi-functional peanut shelling device, which can effectively reduce the spindle speed to reduce the peanut kernel breakage rate, while also increasing the screening area through the umbrella-shaped rice sieve. Through the open crushing chamber, it uses a human hand-kneading method to remove shells, avoiding the drawback of high breakage rate caused by forced breakage due to internal pressure, thereby improving shelling efficiency.
[0005] This utility model provides a vertical umbrella-shaped peanut multifunctional shelling device, including: a shelling chamber, a vertical rotating umbrella-shaped rice sieve located in the shelling chamber, and a crushing frame. The vertical rotating umbrella-shaped rice sieve is rotatably connected to the shelling chamber via a power main shaft. The crushing frame is fixed to the shelling chamber and located above the vertical rotating umbrella-shaped rice sieve. A gap for crushing peanut shells is provided between the vertical rotating umbrella-shaped rice sieve and the crushing frame. Peanuts entering the shelling chamber fall onto the vertical rotating umbrella-shaped rice sieve and, driven by the vertical rotating umbrella-shaped rice sieve, come into contact with the crushing frame, causing the peanut shells to be crushed. The peanut kernels and crushed peanut shells are discharged from the shelling chamber through the holes of the vertical rotating umbrella-shaped rice sieve.
[0006] As a preferred embodiment of this utility model, the vertical rotating umbrella-shaped rice sieve includes an umbrella-shaped sieve and a shaft seat fixed to the center of the umbrella-shaped sieve and connected to the main power shaft. The umbrella-shaped sieve is mounted on the main power shaft through the shaft seat, and the vertically arranged main power shaft drives the umbrella-shaped sieve to rotate around the axis.
[0007] As a preferred embodiment of this utility model, the vertical rotating umbrella-shaped rice sieve includes an umbrella-shaped sieve grate, and the power main shaft is used to drive the umbrella-shaped sieve grate to rotate in a direction perpendicular to the ground.
[0008] As a preferred embodiment of this utility model, the umbrella-shaped sieve of the vertical rotating umbrella-shaped rice sieve includes: an umbrella-shaped frame composed of at least four screening surfaces, wherein the included angle between the sieve bars of two adjacent screening surfaces is between 0 degrees and less than 90 degrees, so that the peanuts passing through the two adjacent screening surfaces change direction to achieve the crushing of peanut shells by kneading.
[0009] As a preferred embodiment of this utility model, the umbrella-shaped sieve of the vertical rotating umbrella-shaped rice sieve consists of eight screening surfaces, and the angle between the sieve bars on each screening surface and the main umbrella rod is 35-45 degrees.
[0010] As a preferred embodiment of this invention, the angle between the grating bars on each screening surface and the main umbrella rod is 41 degrees.
[0011] As a preferred embodiment of this invention, the angle between the screen surface of the vertical rotating umbrella-shaped rice sieve and the ground is between 20 and 60 degrees.
[0012] As a preferred embodiment of this utility model, the crushing frame includes multiple rice-peeling rods, which are fixedly connected to the shelling chamber and are used to rub and crush peanuts in conjunction with a vertical rotating umbrella-shaped rice sieve.
[0013] As a preferred embodiment of this utility model, the rice-pulling frame further includes a connecting rod, and two adjacent rice-pulling rods are fixedly connected by the connecting rod. The multiple rice-pulling rods and the multiple connecting rods form an umbrella-shaped rice-pulling frame that covers the vertical rotating umbrella-shaped rice sieve. One end of the multiple rice-pulling rods is gathered and fixedly connected to the lifting seat above the power main shaft, and the other end of the multiple rice-pulling rods is fixedly connected to the inner wall of the hulling chamber.
[0014] As a preferred embodiment of this utility model, the rice-breaking frame further includes: a resilient kneading belt (rubber material) installed on the rice-pulling rod, the kneading edge of the resilient kneading belt contacting the vertical rotating umbrella-shaped rice sieve, and the resilient kneading belt being used to discharge peanuts and broken peanut shells from the holes of the vertical rotating umbrella-shaped rice sieve.
[0015] As a preferred embodiment of this utility model, the shelling chamber includes a cylindrical fixed chamber with openings at the top and bottom and a rotating chamber located below the cylindrical fixed chamber. The upper edge of the rotating chamber extends to a position higher than the lower edge of the cylindrical fixed chamber. The lower edge of the rotating chamber is fixedly connected to the bottom edge of the vertical rotating umbrella-shaped rice sieve. The rotating chamber rotates with the vertical rotating umbrella-shaped rice sieve. A bolt adjustment seat is fixedly connected to the outer side of the cylindrical fixed chamber. A support rod is provided on the overall frame corresponding to the position of the bolt adjustment seat. The height position of the cylindrical fixed chamber relative to the overall frame is adjusted by the bolt adjustment seat and the threaded rod, thereby adjusting the gap height between the rice-scooping rod fixed on the cylindrical fixed chamber and the vertical rotating umbrella-shaped rice sieve.
[0016] As a preferred embodiment of this utility model, the power spindle is fixed to the overall frame via a bearing seat, and the power spindle is connected to the drive motor via a pulley, chain, or intermediate linkage mechanism. The drive motor drives the power spindle to rotate the vertical rotating umbrella-shaped rice sieve.
[0017] The advantages and positive effects of this utility model are:
[0018] 1. This utility model replaces the existing horizontal barrel-shaped rice sieve with a vertical rotating umbrella-shaped rice sieve. Due to the use of vertical screening, the actual shelling area is much larger than that of the horizontal barrel-shaped rice sieve, which can reduce the motor speed and improve the breakage rate of peanut kernel shelling.
[0019] 2. This utility model uses a rice sieve as a rotating component instead of the existing method where the rice sieve is stationary and the striking rod moves, so as to facilitate the adjustment of the gap between the rice sieve and the striking rod.
[0020] 3. The rotating umbrella-shaped rice sieve of this utility model adopts a zoned sieve surface. By dividing the sieve bars of adjacent areas into different oblique angles, the peanuts that slide naturally down the umbrella surface will rotate naturally when passing through the sieve surface of different areas, so as to achieve the peanut shelling by hand kneading. Compared with the crushing method, this method is less damaging to the peanuts, thereby reducing the peanut breakage rate.
[0021] 4. This utility model, by installing a tough kneading strap on the rice-pulling rod to assist the rice-pulling rod in kneading the peanuts, can also push the shelled peanut kernels out of the grate holes to prevent the peanut kernels from being crushed by secondary compression.

[0030] See Figure 1-7This embodiment provides a vertical umbrella-shaped peanut multifunctional shelling device, including: a shelling chamber 1, two vertical rotating umbrella-shaped rice sieves 2 located in the shelling chamber 1, and two crushing frames 3. The vertical rotating umbrella-shaped rice sieves 2 are rotatably connected to the shelling chamber 1 via a power main shaft 5. The crushing frames 3 are fixedly connected to the shelling chamber 1 and located above the vertical rotating umbrella-shaped rice sieves 2. A gap 4 for crushing peanut shells is provided between the vertical rotating umbrella-shaped rice sieves 2 and the crushing frames 3. Peanuts entering the shelling chamber 1 fall onto the vertical rotating umbrella-shaped rice sieves 2 and, driven by the vertical rotating umbrella-shaped rice sieves 2, come into contact with the crushing frames 3, causing the peanut shells to be crushed. The peanut kernels and crushed peanut shells are discharged from the shelling chamber through the holes of the vertical rotating umbrella-shaped rice sieves 2. The vertical rotating umbrella-shaped rice sieve 2 includes an umbrella-shaped sieve and a shaft seat 6 fixed to the center of the umbrella-shaped sieve and connected to the main power shaft 5. The umbrella-shaped sieve is mounted on the main power shaft 5 via the shaft seat 6, and the shaft seat 6 is integrally formed with or separate from the umbrella-shaped sieve. The vertically arranged main power shaft 5 drives the umbrella-shaped sieve to rotate around its axis. The umbrella-shaped sieve includes an umbrella-shaped frame composed of eight screening surfaces 7, wherein the included angle between the sieve bars of two adjacent screening surfaces is between 0 degrees and less than 90 degrees, allowing the peanuts passing through adjacent screening surfaces to change direction, thereby crushing the peanut shells by kneading. The inclination angle between each screening surface 7 and the umbrella frame is 41 degrees. The angle between the sieve surface of the vertical rotating umbrella-shaped rice sieve 2 and the ground is 30 degrees. The vertical rotating umbrella-shaped rice sieve 2, with its angled sieve bars on the sieve surface 7, causes the peanuts falling into the shelling chamber 1 to rotate with the vertical rotating umbrella-shaped rice sieve 2 after contacting it, and to be crushed by the rubbing of the two adjacent sieve surfaces 7 and the crushing frame 3.
[0031] Furthermore, the crushing frame 3 in this embodiment includes: a rice-scraping rod 8, a resilient kneading belt 9 mounted on the rice-scraping rod 8, and a connecting rod 16 connecting two adjacent rice-scraping rods 8. The resilient kneading belt 9 is made of hard rubber, and its kneading edge contacts the upper surface of the vertical rotating umbrella-shaped rice sieve 2. The resilient kneading belt 9 is used to discharge peanuts and broken peanut shells from the holes of the vertical rotating umbrella-shaped rice sieve 2 to prevent secondary crushing of peanut kernels. The rice-scraping rod 8 is used to cooperate with the vertical rotating umbrella-shaped rice sieve 2 to knead and crush peanuts. Among them, eight rice-scraping rods and two sets of sixteen connecting rods form an umbrella-shaped crushing frame 3 covering the vertical rotating umbrella-shaped rice sieve 2. One end of the eight rice-scraping rods is gathered and fixed to the lifting seat 19 above the power main shaft, and the other end of the eight rice-scraping rods is fixed to the inner wall of the shelling chamber. The wall-breaking frame 3 is lifted by the lifting seat 19 to facilitate subsequent adjustment of the gap between the vertical rotating umbrella-shaped rice sieve 2 and the wall-breaking frame 3. The lifting seat 19 is connected to the hoist 22 installed on the overall frame 13. The hoist 22 drives the wall-breaking frame 3 to adjust its height through the lifting seat 19.
[0032] Furthermore, in this embodiment, the shelling chamber 1 includes a cylindrical fixed chamber 10 with openings at the top and bottom and a rotating chamber 11 located below the cylindrical fixed chamber 10. The upper edge of the rotating chamber 11 extends to a position higher than the lower edge of the cylindrical fixed chamber 10. The diameter of the rotating chamber 11 is slightly larger than the diameter of the cylindrical fixed chamber 10 to ensure that it can surround the bottom edge of the cylindrical fixed chamber 10. The lower edge of the rotating chamber 11 is fixedly connected to the bottom edge of the vertical rotating umbrella-shaped rice sieve 2. The vertical rotating umbrella-shaped rice sieve 2 and the rotating chamber 11 are integrally formed. The vertical rotating umbrella-shaped rice sieve 2 is welded into an umbrella shape by steel bars, and the annular rotating chamber 11 is welded on the outer circumference of the bottom.
[0033] The rotating chamber 11 rotates with the vertical rotating umbrella-shaped rice sieve 2. The cylindrical fixed chamber 10 is fixedly connected to the outside of the bolt adjustment seat 12. The support rod 14 is set on the overall frame 13 corresponding to the position of the bolt adjustment seat 12. The cylindrical fixed chamber 10 adjusts its height position relative to the overall frame 13 through the bolt adjustment seat 12 and the support rod 14, thereby adjusting the gap height between the rice-scooping rod 8 fixed on the cylindrical fixed chamber 10 and the vertical rotating umbrella-shaped rice sieve 2.
[0034] Furthermore, in this embodiment, the main power shaft 5 is vertically fixed to the overall frame 13 via a bearing seat. The main power shaft 5 is connected to the reduction gear 18 via a sprocket and a chain 17. The reduction gear 18 is connected to the output shaft of the drive motor 15 via a transmission belt 20. The drive motor 15 drives the main power shaft 5 to rotate the vertical rotating umbrella-shaped rice sieve 2.
[0035] Furthermore, in this embodiment, two shelling chambers 1 are installed on the overall frame 13 to improve the overall shelling efficiency of the device, and two conveyor belts 21 are provided below the shelling chambers 1 for conveying peanut kernels.
[0036] Working principle: The vertically rotating umbrella-shaped rice sieve 2, arranged in an umbrella shape, rotates vertically within the shelling chamber 1. Peanuts entering from above the shelling chamber 1 fall onto the rotating vertically rotating umbrella-shaped rice sieve 2. The vertically rotating umbrella-shaped rice sieve 2 causes the peanuts to come into contact with the rice-peeling rod 8 and the resilient kneading belt 9. After contacting the upper surface of the vertically rotating umbrella-shaped rice sieve 2, the peanuts slide downwards along the umbrella surface due to gravity and slide in a downward direction under the action of the inclined grate bars. When passing the rice-peeling rod 8 and the dividing point of the two sieve surfaces 7, they will rotate naturally, allowing the peanuts to be shelled in a manner that mimics human hand kneading. After being shelled, the peanut kernels fall from the grate holes into the conveyor belt under the action of the resilient kneading belt 9.
[0037] The processing method of vertical rotating umbrella-shaped rice sieve includes the following steps:
[0038] Step S1: Prepare the central shaft seat, umbrella shaft rib, grate bar, and circular umbrella shaft seat for connecting the power spindle 5;
[0039] Step S2: Weld one end of the eight evenly distributed umbrella shaft ribs to the shaft seat and the other end to the circular umbrella shaft seat to form the main umbrella frame;
[0040] Step S3: Weld eight screening surfaces 7 onto the main umbrella frame. Each screening surface 7 is welded with a grate bar at the same angle, starting from one umbrella shaft rib. One end of the grate bar is welded to the umbrella shaft rib, and the other end is welded to the circular umbrella shaft base.
