Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly relates to a peanut shelling device for peanut processing. Background Art

[0002] Peanuts, originally named groundnuts, are a kind of nut with rich production and wide consumption in China, also known as "life prolonging fruits", "mud beans", "foreign beans", etc. They belong to the Rosales order and are annual herbaceous plants of the Leguminosae family. The stems are erect or prostrate, 30 - 80 cm long. The wing petals are separated from the keel petals. The pods are 2 - 5 cm long and 1 - 1.3 cm wide, inflated, with thick pods. The flowering and fruiting period is from June to August. They are mainly distributed in Brazil, China, Egypt, etc. They can be used as raw materials for making soaps and hair oils and other cosmetics. With the progress of society, industrialization is becoming more and more common, and various jobs are replaced by machines. Peanut shelling in agricultural operations is one example.

[0003] After retrieval, a Chinese invention patent, with the publication number: CN109349653B, and the name: A multifunctional peanut shelling device. This invention includes: a peanut screening mechanism, a peanut shelling mechanism, a vibrating feeding mechanism, and a peanut shell compression mechanism. The device can continuously feed automatically, can shell peanuts, can separate peanuts and peanut shells, can blow peanut shells together for collection, and can compress peanut shells.

[0004] However, in the actual use process, the above - mentioned and similar technical solutions still have some problems:

[0005] 1. In the peanut shelling operation system based on a rotating shelling wheel and a fixed mesh cylinder, there is a poor coordination between peanut shelling and screening. Specifically, under the rotational pushing action of the shelling wheel, peanuts show a sliding motion trend on the inner wall of the mesh cylinder, resulting in a serious uneven distribution of the extrusion force exerted by the shelling wheel on the peanut circumference. This non - uniform extrusion causes local stress concentration on the peanut shell, easily leading to unilateral rupture and shedding of the shell, and even peanut grain breakage, affecting product quality.

[0006] 2. The narrow gap design between the shelling wheel and the mesh cylinder limits the movement space of peanuts. The broken shells half - wrapping peanuts and un - shelled small peanuts, due to their irregular geometric shapes and abnormal equivalent particle sizes, are prone to dynamic interference with the sieve holes when passing through the mesh cylinder and penetrate the sieve mesh in an abnormal posture, which affects the workload of re - selection.

[0007] 3. Under the action of wind force, although a certain degree of spatial separation between peanut shells and peanut grains is achieved, some peanuts are still in an adhesive state. The peanut shells and peanut grains fall together, with a large mass, and it is easy to have a situation where they cannot be separated by wind force, lacking a collision mechanism. Summary of the Invention

[0008] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a peanut processing shelling device which can make the peanuts evenly stressed, prevent the peanuts from directly passing through the mesh holes, and effectively separate the peanut shells and peanut kernels.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A shelling device for peanut processing, comprising a shell, a hopper is installed at the top of the shell, a shelling mechanism is connected to the shell, the shelling mechanism comprises an inner rotating disk, the top of the shell is rotatably connected to the inner rotating disk, the shell is located outside the inner rotating disk and is rotatably connected to the outer rotating disk, a guide disk is arranged between the inner rotating disk and the outer rotating disk, a guide groove is arranged on the guide disk, the top of the guide groove is connected to the hopper, the guide groove is used to introduce peanuts, and the peanuts are rubbed by the rotation of the inner rotating disk and the outer rotating disk, so as to break the peanut shells;

[0011] A separation mechanism is connected to the bottom of the shell, and the separation mechanism includes a mounting cylinder. A mounting cylinder is installed inside the bottom end of the shell, and a second motor is connected to the mounting cylinder. An impeller is installed on the output shaft of the second motor, so as to facilitate the separation of peanut kernels and peanut shells by wind force.

[0012] Preferably, the inner rotating disk rotates in opposite directions to the outer rotating disk, and the guide disk and the outer rotating disk are both truncated cone-shaped rings. The inner rotating disk is truncated cone-shaped, so that an angular velocity difference is formed between the top and bottom ends of the peanuts, which promotes the crushing of the peanut shells and the downward movement of the peanuts.

[0013] Preferably, there are multiple guide grooves distributed in a circular array, and the guide groove is waist-shaped. The top of the guide groove is arranged below the discharge port of the hopper, and the bottom of the guide groove is arranged outside the bottom end of the inner rotating disk, so as to facilitate the introduction of more peanuts into the guide groove, thereby facilitating the shelling of the peanuts.

[0015] Preferably, a plurality of springs are installed between the guide plate and the hopper, and the plurality of springs are arranged in a circular array. A top column is installed on the inner side of the outer rotating plate, and the end of the top column contacts the outer wall of the guide plate, and the guide plate is tilted, thereby limiting the rotation of the guide plate.

[0016] Preferably, a driving assembly is connected to the installation cylinder. The driving assembly includes a first motor. The first motor is installed at the top end of the installation cylinder. The inner rotating disk is fixedly connected to the output shaft of the first motor. A support column is fixedly connected to the top end of the installation cylinder. A second gear is rotatably connected to the support column. A fixed shell is rotatably connected between the inner rotating disk and the outer rotating disk. The fixed shell is fixedly connected to the support column. A first gear is installed at the bottom end of the inner rotating disk. An internal gear is installed at the bottom end of the outer rotating disk. The two ends of the second gear are respectively meshed with the first gear and the internal gear. The first motor drives the inner rotating disk to rotate, driving the first gear to rotate. Under the transmission of the second gear, the internal gear and the outer rotating disk are driven to rotate. The inner rotating disk and the outer rotating disk rotate in opposite directions. The position of the guide disk remains unchanged. The outer wall of the inner rotating disk and the inner wall of the outer rotating disk are rough, so as to perform rolling friction on the peanuts.

[0017] Preferably, there are a pair of the second gears. The fixed shell is in a slope shape above the second gears to prevent the second gears from squeezing the peanuts.

[0018] Preferably, the second motor is installed inside the installation cylinder. The second motor is suspended. The installation cylinder is provided with mesh holes on the outer periphery of the impeller. The bottom of the installation cylinder communicates with the cavity where the impeller is located, facilitating the inhalation of air.

[0019] Preferably, a plurality of blocking rods are fixedly connected to the outer periphery of the installation cylinder where the mesh holes are located. The plurality of blocking rods are arranged in a circular and staggered manner, so as to slow down the falling speed of the peanut grains and shells and facilitate the separation by the wind.

[0020] Preferably, the top end of the outer shell is in a funnel-shaped structure. The outer shell is provided with a falling groove at the bottom end of the funnel shape. The blocking rods extend into the interior of the falling groove. The bottom end of the falling groove is inclined. The outer shell is provided with a first discharge plate on the outer wall of the lowest side of the falling groove. The first discharge plate communicates with the bottom end of the inclined part of the falling groove. The outer shell is provided with a communicating blowing groove outside the falling groove. The bottom end of the blowing groove is inclined. The outer shell is provided with a second discharge plate on the outer wall of the lowest side of the blowing groove. The second discharge plate communicates with the bottom end of the inclined part of the blowing groove, so as to facilitate the separate discharge of the peanut grains and peanut shells.

[0021] Compared with the prior art, the present invention provides a peanut shelling device for peanut processing, which has the following beneficial effects:

[0022] 1. For the peanut shelling device used for peanut processing, the peanuts are in contact with the top outer wall of the guide plate. The peanuts enter the guide groove. The first motor is started to drive the inner rotating disc and the outer rotating disc to rotate in opposite directions. The position of the guide plate remains unchanged. The outer wall of the inner rotating disc and the inner wall of the outer rotating disc are rough, so as to perform rolling friction on the peanuts. Since the guide plate, the inner rotating disc and the outer rotating disc are all frustum-shaped, an angular velocity difference is formed between the top and the bottom of the peanuts, and the angular velocity difference promotes the crushing of the peanut shells and at the same time promotes the downward movement of the peanuts, thus ensuring the shelling rate.

[0023] 2. For the peanut shelling device used for peanut processing, when the outer rotating disc rotates, the top column rotates, thereby pushing the guide plate to swing in a circular motion. The guide plate swings through the rotating ball, and the spring plays a limiting role to limit the rotation of the guide plate. When the top column pushes the guide plate away, the distance between one side of the guide plate and the outer rotating disc will increase, so as to facilitate the peanuts to enter the guide groove. The peanuts inside the guide groove will tend to the outside. When the distance between one side of the guide plate and the outer rotating disc becomes smaller, the peanuts will tend to the inside. Thus, by continuously switching the positions of the peanuts, the irregular peanuts will tilt, facilitating their contact and friction with the rotating discs for shelling, and facilitating the separation of peanut kernels and peanut shells, thus facilitating the next sieving step.

[0024] 3. For the peanut shelling device used for peanut processing, the peanut kernels and peanut shells will fall onto the upper end of the outer shell and enter the inside of the falling groove. The second motor is started, and the wind blows out from the mesh holes. Under the action of the blocking rod, the peanut kernels and peanut shells will be blocked, slowing down the falling speed of the peanut kernels and peanut shells. The peanut shells are lighter, so it is easy for the wind to blow the peanut shells away from the falling groove. The peanut kernels are heavier, so they enter the bottom of the falling groove, thus facilitating the separation of peanut kernels and peanut shells. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In the present invention, the inner rotating disk 35 rotates in a direction opposite to that of the outer rotating disk 31, thereby driving the peanuts to rotate. When the peanuts rotate, the entire peripheral wall of the peanuts can be squeezed, so as to uniformly crush the peanut shells. The guide disk 32 and the outer rotating disk 31 are both in the shape of a frustum-shaped ring, and the inner rotating disk 35 is in the shape of a frustum, so as to form an angular velocity difference between the top and the bottom of the peanuts. The angular velocity difference promotes the crushing of the peanut shells and at the same time promotes the downward movement of the peanuts.

[0039] In the present invention, a plurality of guide grooves 33 are provided. The plurality of guide grooves 33 are distributed in an annular array. The guide grooves 33 are in the shape of a waist. The top end of the guide groove 33 is located below the discharge port of the hopper 2, and the bottom end of the guide groove 33 is located outside the bottom end of the inner rotating disk 35, so as to facilitate the introduction of more peanuts into the guide grooves 33, and thus facilitate the shelling of the peanuts.

[0040] In the present invention, a driving assembly 34 is connected to the mounting cylinder 48. The driving assembly 34 includes a first motor 341. The first motor 341 is installed at the top end of the mounting cylinder 48. The inner rotating disk 35 is fixedly connected to the output shaft of the first motor 341. A support column 346 is fixedly connected to the top end of the mounting cylinder 48. A second gear 345 is rotatably connected to the support column 346. A fixed shell 343 is rotatably connected between the inner rotating disk 35 and the outer rotating disk 31. The fixed shell 343 is fixedly connected to the support column 346. A first gear 344 is installed at the bottom end of the inner rotating disk 35. An internal gear 342 is installed at the bottom end of the outer rotating disk 31. The two ends of the second gear 345 are respectively engaged with the first gear 344 and the internal gear 342. The first motor 341 drives the inner rotating disk 35 to rotate, driving the first gear 344 to rotate. Under the transmission of the second gear 345, the internal gear 342 and the outer rotating disk 31 are driven to rotate. The inner rotating disk 35 and the outer rotating disk 31 rotate in opposite directions, and the position of the guide disk 32 remains unchanged. The outer wall of the inner rotating disk 35 and the inner wall of the outer rotating disk 31 are rough, so as to perform rolling friction on the peanuts.

[0041] In the present invention, a pair of second gears 345 are provided. The fixed shell 343 is in a slope shape above the second gear 345, so as to prevent peanuts from falling between the teeth of the second gear 345 and avoid affecting the operation of the second gear 345.

[0042] Embodiment 2: On the basis of Embodiment 1, a peanut processing shelling device, the bottom of the outer shell 1 is connected with a separation mechanism 4. The separation mechanism 4 includes a mounting cylinder 48. The mounting cylinder 48 is installed inside the bottom end of the outer shell 1. A second motor 43 is connected to the mounting cylinder 48. An impeller 49 is installed on the output shaft of the second motor 43, so as to facilitate the separation of peanut grains and peanut shells by wind power.

[0043] In the present invention, the second motor 43 is installed inside the installation cylinder 48. The second motor 43 is suspended in the air. The installation cylinder 48 is provided with mesh holes 44 on the outer periphery of the impeller 49. The bottom of the installation cylinder 48 communicates with the cavity where the impeller 49 is located, so as to facilitate driving the impeller 49 to rotate through the second motor 43, sucking external air into the inside of the installation cylinder 48, and then blowing it out through the mesh holes 44, thereby facilitating the separation of the fallen peanut grains and peanut shells.

[0044] In the present invention, a plurality of blocking rods 45 are fixedly connected to the outer periphery of the installation cylinder 48 at the mesh holes 44. The plurality of blocking rods 45 are arranged in a circular and staggered manner. The staggered blocking rods 45 can slow down the falling speed of the peanut grains and peanut shells, thereby giving more time for separation by wind force.

[0045] In the present invention, the top end of the outer shell 1 is in a funnel-shaped structure, so as to facilitate the collection of peanut grains and peanut shells into the wind screening end. The outer shell 1 is provided with a falling groove 46 at the bottom of the funnel shape. The blocking rods 45 extend into the inside of the falling groove 46. The bottom end of the falling groove 46 is inclined. The outer shell 1 is provided with a first discharge plate 41 on the outer wall of the lowest side of the falling groove 46. The first discharge plate 41 communicates with the bottom end of the inclined part of the falling groove 46. The peanut grains are heavier and enter the bottom of the falling groove 46, so as to facilitate discharge through the first discharge plate 41. The outer shell 1 is provided with a communicating blowing groove 47 outside the falling groove 46. The bottom end of the blowing groove 47 is inclined. The outer shell 1 is provided with a second discharge plate 42 on the outer wall of the lowest side of the blowing groove 47. The second discharge plate 42 communicates with the bottom end of the inclined part of the blowing groove 47. The peanut shells are lighter, and the wind blows the peanut shells away from the falling groove 46 and makes them enter the blowing groove 47, so as to facilitate the discharge of the peanut shells through the second discharge plate 42.

[0046] Embodiment 3: On the basis of Embodiment 2, a peanut shelling device for peanut processing. The outer rotating disk 31 is rotatably connected to the bottom end of the hopper 2. The hopper 2 is connected with an adjusting mechanism 5. The adjusting mechanism 5 includes a top block 52. The top block 52 is installed in the bottom end inside of the hopper 2 and is suspended in the air. The bottom end of the top block 52 is fitted with a rotating ball 53 in a rotating manner. The bottom end of the rotating ball 53 is fixedly connected to the top end of the guide disk 32. The guide disk 32 can swing in a circular motion along the center of the rotating ball 53 through the rotating ball 53, avoiding the deviation of the guide disk 32.

[0047] In the present invention, a plurality of springs 51 are installed between the guide disk 32 and the hopper 2. The plurality of springs 51 are arranged in a circular array, thereby restricting the rotation of the guide disk 32. A top column 54 is installed inside the outer rotating disk 31. The end of the top column 54 abuts against the outer wall of the guide disk 32. The guide disk 32 is inclined, so as to facilitate pushing the guide disk 32 to swing, forming a gap between the peanut grains and peanut shells in the guide groove 33, and facilitating separation during falling.

[0048] Working principle: Place the peanuts to be shelled inside the hopper 2. The peanuts come into contact with the top outer wall of the guide plate 32 and enter the guide groove 33. Start the first motor 341. The first motor 341 drives the inner rotating disc 35 to rotate, driving the first gear 344 to rotate. Under the transmission of the second gear 345, the inner gear 342 and the outer rotating disc 31 are driven to rotate. The inner rotating disc 35 and the outer rotating disc 31 rotate in opposite directions, and the position of the guide plate 32 remains unchanged. The outer wall of the inner rotating disc 35 and the inner wall of the outer rotating disc 31 are rough, so as to perform rolling friction on the peanuts. Since the guide plate 32, the inner rotating disc 35 and the outer rotating disc 31 are all frustum-shaped, an angular velocity difference is formed between the top and the bottom of the peanuts, which promotes the crushing of the peanut shells and at the same time promotes the downward movement of the peanuts, thus ensuring the shelling rate;

[0049] When the outer rotating disc 31 rotates, the ejector pin 54 rotates, thus pushing the guide plate 32 to swing in a circular motion. The guide plate 32 swings through the rotating ball 53, and the spring 51 plays a limiting role to limit the rotation of the guide plate 32. When the ejector pin 54 pushes the guide plate 32 away, the distance between one side of the guide plate 32 and the outer rotating disc 31 will increase, which is convenient for peanuts to enter the guide groove 33. The peanuts inside the guide groove 33 will tend to the outside. When the distance between one side of the guide plate 32 and the outer rotating disc 31 becomes smaller, the peanuts will tend to the inside, so as to facilitate the separation of peanut grains and peanut shells by continuously switching the positions of the peanuts, thus facilitating the next screening step;

[0050] The peanut grains and peanut shells will fall onto the upper end of the outer shell 1 and enter the inside of the falling groove 46. Start the second motor 43. The second motor 43 drives the impeller 49 to rotate, thus sucking the external air into the installation cylinder 48 and blowing it out through the mesh holes 44. The wind blows into the falling groove 46. Under the action of the blocking rod 45, the peanut grains and peanut shells will be blocked, slowing down the falling speed of the peanut grains and peanut shells. The peanut shells are lighter, so it is convenient for the wind to blow the peanut shells away from the falling groove 46. The peanut shells enter the inside of the blowing groove 47 and are discharged from the second discharge plate 42. The peanut grains are heavier, so they enter the bottom of the falling groove 46 and are discharged from the first discharge plate 41, thus facilitating the separation of peanut grains and peanut shells.

[0051] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
