Description

Technical Field

[0001] This invention relates to the field of walnut processing technology, specifically to an automatic walnut shell and kernel sorting device and sorting method. Background Technology

[0002] Walnuts have extremely high nutritional value; their roots, stems, leaves, and fruits all have uses, making them a veritable treasure trove. They are one of the most widely distributed economic tree species in China. China primarily processes walnut kernels, with main products including walnut kernel foods, walnut oil, and walnut health products, fully demonstrating the immense nutritional value of walnut cultivation and processing. To facilitate walnut processing, shelling is necessary, followed by kernel separation. Traditional walnut shell-kernel sorting methods are inconvenient for separating and classifying the shells and kernels.

[0003] Chinese patent CN114886125B discloses a method and apparatus for sorting walnut shells and kernels. An electric pusher brings a pressure plate and a support plate closer together to squeeze the walnuts, separating the shells from the kernels. A feeding ramp guides the shells and kernels onto a conveyor belt. A blower provides airflow in the opposite direction to the conveyor belt's transport direction, preventing the shells from moving with the belt and thus completing the sorting. While this method separates the shells and kernels by directing the airflow relative to the conveyor belt's direction, the weight of the separated shells and kernels is not fixed. There are instances where kernels are carried away by the wind and the shells remain unaffected. Furthermore, as the shells and kernels continuously move onto the conveyor belt, some shells, after traveling a certain distance, accumulate with others behind the belt, at which point the wind can no longer propel them further. Summary of the Invention

[0004] To address the aforementioned issues, an automatic walnut shell kernel sorting device is provided. Through the cooperation of a processing frame and a movable plate, kernels placed inside damaged walnut shells that have entered the processing frame will leave the damaged shells. The kernels will break into smaller pieces due to impact. A storage shell limits the position of the walnut kernels as they are output onto the conveyor belt. The conveyor belt and an air outlet assembly allow kernels and walnut shells of different weights to exit from the first and second discharge ports, respectively.

[0005] To address the problems of existing technologies, an automatic walnut shell sorting device is provided, comprising a sorting box, two conveyor belts fixedly installed inside the sorting box and facing each other, an air outlet assembly fixedly installed between the two conveyor belts with its outlet facing the two conveyor belts, and a sorting pretreatment assembly. The sorting pretreatment assembly includes a processing frame, a movable plate, and a discharge frame. The top surface of the sorting box has inlets that guide the walnut shells to be sorted into the two conveyor belts. First discharge ports are located on the bottom surfaces at both ends of the sorting box along the conveyor belt's transport direction, and a second discharge port is located on the bottom surface of the sorting box at the center of the two conveyor belts. The processing frame is fixed. A processing frame is installed inside the sorting box, with the center of each conveyor belt positioned above it. The opening of the processing frame is vertical, and the processing frame is directly below the feed inlet. A movable plate is slidably installed inside the processing frame, sliding horizontally and perpendicular to the transport direction of the conveyor belt. The movable plate performs reciprocating linear motion. A discharge frame is fixed between the processing frame and the conveyor belt, with its opening vertical. A storage shell is rotatably installed on the discharge frame away from the opening of the processing frame. The rotation axis of the storage shell is parallel to the transport direction of the conveyor belt. The storage shell has through holes for walnut shell kernels to pass through, and the storage shell performs pendulum-like motion.

[0006] Preferably, the sorting pretreatment component further includes a fixing frame, the number of fixing frames is two, the fixing frame is provided with fixing holes for fixing the processing frame and the discharge frame, the number of processing frames is at least two, and all processing frames are evenly arranged along the vertical direction.

[0007] Preferably, the sorting pretreatment component further includes an output gear and a servo motor. The output gear is rotatably mounted inside the sorting box. The axis of the output gear is vertically set and the height of the output gear is not higher than the discharge frame. An extension rod extending upward is coaxially fixed on the output gear. A fixed sleeve is coaxially fixed on the extension rod. Two fixed strips are fixedly fixed on the outer wall of the fixed sleeve and evenly arranged around the axis of the fixed sleeve. A movable strip is slidably mounted on the outside of the processing frame. The sliding direction of the movable strip is parallel to the movable plate and the two move synchronously. When the fixed strip rotates with the output gear, it can contact the movable strip.

[0008] Preferably, the processing frame further includes an elastic connector, one end of which is fixedly connected to the movable strip, and the other end of which is fixedly connected to the processing frame.

[0009] Preferably, the number of fixed sleeves is the same as the number of processing frames and their positions correspond one-to-one, and the fixing strips on two adjacent fixed sleeves are perpendicular to each other.

[0010] Preferably, two feed inclines are fixedly installed at the bottom of the processing frame. The line connecting the two feed inclines is parallel to the sliding direction of the movable plate. The feed inclines are used to guide the walnut shell kernels in the processing frame to leave from the center of the processing frame.

[0011] Preferably, one end of the movable strip can extend into the interior of the processing frame, and the movable plate is provided with a long groove that can be inserted into the movable strip.

[0012] Preferably, the processing frames are fitted together, and the processing frames and the discharge frames are fitted together.

[0013] Preferably, the discharge frame further includes a rotating disk, and an L-shaped bracket for rotating the rotating disk is fixedly installed on the discharge frame. The rotating disk and the output gear are connected by bevel gear transmission. The axis of the rotating disk is parallel to the transport direction of the conveyor belt. An eccentric first fixed shaft is fixedly installed on the rotating disk, and a second fixed shaft is fixedly installed on the discharge frame. A connecting strip is fixedly installed on the storage shell. The connecting strip has a limiting groove that can slide with the first fixed shaft, and a round hole that can be shafted with the second fixed shaft.

[0014] An automatic sorting method for walnut shells and kernels, using the aforementioned automatic sorting equipment for walnut shells and kernels, includes the following steps:

[0015] S1. After pressing whole walnuts, a mixture of walnut kernels is obtained. The mixture of walnut kernels is then poured into the feed inlet.

[0016] S2. The walnut kernels enter the processing frame through the feed inlet. At this time, the movable plate in the processing frame is in reciprocating linear motion. While the movable plate is moving, it continuously impacts the walnut kernel mixed raw material, causing the kernels placed inside the walnut shell to leave the walnut shell and the kernels that leave the walnut shell to break.

[0017] S3. The walnut kernel mixture after passing through the processing frame enters the discharge frame. The storage shell, which moves in a pendulum motion, outputs the walnut kernel mixture onto the conveyor belt. The walnut kernel mixture is distributed in a sinusoidal curve on the conveyor belt.

[0018] S4. The air outlet component blows out air, causing the lighter kernels to move with the air and leave from the first discharge port, while the heavier walnut shells leave from the second discharge port along with the conveyor belt.

[0019] The advantages of this invention compared to the prior art are:

[0020] This invention, through the cooperation of a processing frame and a movable plate, enables the kernels placed inside the broken walnut shells to leave the shells upon entering the processing frame. The kernels are broken into smaller pieces due to impact. The storage shell limits the position of the kernels as they are output onto the conveyor belt. The conveyor belt and the air outlet assembly allow kernels and shells of different weights to exit through the first and second discharge ports, respectively. This ensures that the weight of the kernels and shells entering the conveyor belt is within a fixed range, preventing the kernels and shells from moving in the same direction due to similar weights. It also ensures that the kernels do not come into contact with other kernels or shells and accumulate on the conveyor belt. Attached Figure Description

Detailed Implementation

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] See Figures 1-5 and Figure 7 As shown, an automatic walnut shell kernel sorting device includes a sorting box 1, two conveyor belts 2 fixedly installed inside the sorting box 1 and arranged in opposite directions, an air outlet assembly 3 fixedly installed between the two conveyor belts 2 with its air outlet facing the two conveyor belts 2, and a sorting pretreatment assembly 4. The sorting pretreatment assembly 4 includes a processing frame 41, a movable plate 42, and a discharge frame 43. The top surface of the sorting box 1 has inlets 11 that guide the walnut shell kernels to be sorted into the two conveyor belts 2 respectively. The bottom surfaces of both ends of the sorting box 1 along the conveying direction of the conveyor belts 2 have first discharge ports 12, and the bottom surface of the sorting box 1 located at the center of the two conveyor belts 2 has a second discharge port 13. The processing frame 41 is fixedly installed inside the sorting box and each conveyor belt 2 has an air outlet 3 fixedly installed between the two conveyor belts 2 with its air outlet facing the two conveyor belts 2. A processing frame 41 is provided above the center of each of the conveyor belts 2. The opening of the processing frame 41 is set vertically. The processing frame 41 is located directly below the feed inlet 11. The movable plate 42 is slidably set inside the processing frame 41. The sliding direction of the movable plate 42 is horizontal and perpendicular to the transport direction of the conveyor belt 2. The movable plate 42 performs reciprocating linear motion. The discharge frame 43 is fixedly set between the processing frame 41 and the conveyor belt 2. The opening of the discharge frame 43 is set vertically. A storage shell 431 is rotatably set on the discharge frame 43 away from the opening of the processing frame 41. The rotation axis of the storage shell 431 is parallel to the transport direction of the conveyor belt 2. The storage shell 431 has a through hole 4311 that allows walnut shell kernels to pass through. The storage shell 431 performs pendulum motion.

[0035] The finished walnuts are processed by extrusion to obtain a walnut kernel mixture. This mixture is then poured into the sorting box 1 through the inlet 11. The mixture exits through the inlet 11 and enters the processing frame 41. The movable plate 42 in the processing frame 41 continuously reciprocates linearly. The moving plate 42 collides with or pushes the walnut kernel mixture against the inner wall of the processing frame 41. Due to the impact, some kernels inside the broken walnut shells will detach, breaking the large kernels into smaller pieces. The walnut kernel mixture passing through the processing frame 41 enters the discharge frame 43. Then, under the pendulum-like movement of the storage tank 431, it is continuously output to the conveyor belt 2. The walnut kernel mixture on the conveyor belt 2 will then exhibit a sinusoidal curve shape. The air outlet component 3 continuously outputs airflow in the opposite direction to the conveyor belt 2. Smaller kernels... The kernels will move with the wind and leave from the first discharge port 12. The heavier walnut shells will be transported by the conveyor belt 2 and leave from the second discharge port 13. Compared with the prior art, the processing frame 41 and the movable plate 42 of the present invention cooperate to make the kernels placed inside the broken walnut shells in the processing frame 41 leave the broken walnut shells. The kernels will be broken into smaller pieces due to impact. The storage shell 431 limits the position of the walnut kernels output to the conveyor belt 2. The conveyor belt 2 and the air outlet component 3 cooperate to make the kernels and walnut shells of different weights leave from the first discharge port 12 and the second discharge port 13 respectively. This ensures that the weight of the walnut shells and kernels entering the conveyor belt 2 is within a fixed range, avoiding the situation where the kernels and kernels move in the same direction due to similar weights. At the same time, it also ensures that the kernels on the conveyor belt 2 will not come into contact with other walnut shells or kernels and will not pile up and move.

[0036] See Figure 2 and Figures 5-8 As shown: The sorting pretreatment component 4 also includes a fixing frame 44. There are two fixing frames 44. The fixing frame 44 is provided with fixing holes 441 that can fix the processing frame 41 and the discharge frame 43. There are at least two processing frames 41. All processing frames 41 are evenly arranged along the vertical direction.

[0037] The mixed walnut kernels leave from the feed inlet 11 and enter the processing frame 41. The mixed walnut kernels entering the first processing frame 41 contain some kernels that are inside the broken walnut shells. In the first processing frame 41, these kernels will leave the broken walnut shells due to collision. The kernels that leave the broken walnut shells will enter the second processing frame 41. The kernels that leave the broken walnut shells will collide again in the second processing frame 41 and break. Multiple processing frames 41 can be set as needed to break the kernels into smaller pieces. Compared with the prior art, the processing frames 41 of the present invention are limited to a minimum number, thereby avoiding the weight of kernels and walnut shells being similar after only one processing frame 41.

[0038] See Figure 2 and Figures 5-9 As shown: The sorting pretreatment component 4 also includes an output gear 45 and a servo motor 46. The output gear 45 is rotatably mounted inside the sorting box 1. The axis of the output gear 45 is vertically set and the height of the output gear 45 is not higher than the discharge frame 43. An extension rod 451 extending upward is coaxially fixed on the output gear 45. A fixed sleeve 452 is coaxially fixed on the extension rod 451. Two fixed strips 453 are fixedly fixed on the outer wall of the fixed sleeve 452 and evenly arranged around the axis of the fixed sleeve 452. A movable strip 411 is slidably mounted on the outside of the processing frame 41. The sliding direction of the movable strip 411 is parallel to that of the movable plate 42 and the two move synchronously. When the fixed strip 453 rotates with the output gear 45, it can contact the movable strip 411.

[0039] The servo motor 46 operates, causing the output gear 45 to rotate. When the output gear 45 rotates, it drives the fixed sleeve 452 on the extension rod 451 to rotate simultaneously. The fixed bar 453 rotates around the axis of the extension rod 451. When the fixed bar 453 rotates to a position close to the processing frame 41, it will contact the movable bar 411. At this time, the fixed bar 453 continues to rotate, thereby pushing the movable bar 411 to move. When the movable bar 411 moves, the movable plate 42 will move simultaneously. When the fixed bar 453 rotates away from the processing frame 41, the fixed bar 453 will no longer contact the movable bar 411. Compared with the prior art, the extension rod 451, fixed sleeve 452, fixed bar 453 and movable bar 411 of the present invention cooperate to enable the movable plate 42 to move with the rotation of the output gear 45, thereby enabling the movable plate 42 within a certain range to move intermittently with the rotation of the output gear 45.

[0040] See Figures 6-9 As shown: The processing frame 41 also includes an elastic connector 412, one end of which is fixedly connected to the movable strip 411, and the other end of which is fixedly connected to the processing frame 41.

[0041] When the movable bar 411 moves along the fixed bar 453, it will compress the elastic connector 412. When the fixed bar 453 is no longer in contact with the movable bar 411, the elastic connector 412 will release the compression state and provide elastic force to push the movable bar 411 to move to the initial position. The movable bar 411 will then drive the movable plate 42 to return to the initial position. Compared with the prior art, the elastic connector 412 of the present invention allows the movable plate 42 to move in the opposite direction along the original path, so that the servo motor 46 does not need to perform forward and reverse rotation to make the movable plate 42 reciprocate.

[0042] See Figures 6-8 As shown: the number of fixed sleeves 452 is the same as the number of processing frames 41 and their positions correspond one-to-one. The fixing strips 453 on two adjacent fixed sleeves 452 are perpendicular to each other.

[0043] The output gear 45 rotates under the operation of the servo motor 46. The fixed bar 453 corresponding to the position of the first processing frame 41 at the top of the vertical direction will rotate around the axis of the extension rod 451. The fixed bar 453 will contact the movable bar 411 on the first processing frame 41 at the top of the vertical direction and push it to move. At this time, the movable bar 411 in the second processing frame 41 at the top of the vertical direction will disengage from the corresponding fixed bar 453. At this time, the movable bar 411 in the second processing frame 41 at the top of the vertical direction will move in the opposite direction to the movable bar 411 on the first processing frame 41 at the top of the vertical direction under the elastic force of the elastic connector 412. Compared with the prior art, the present invention limits the position of the fixed bar 453 on the adjacent fixed sleeves 452, so that the movable plate 42 in the adjacent processing frames 41 moves in opposite directions, thereby preventing the mixed raw materials of walnut kernels from directly passing through the processing frame 41.

[0044] See Figures 8-9 As shown: Two feed inclines 413 are fixedly installed at the bottom of the processing frame 41. The line connecting the two feed inclines 413 is parallel to the sliding direction of the movable plate 42. The feed inclines 413 are used to guide the walnut shell kernels in the processing frame 41 to leave from the center of the processing frame 41.

[0045] The walnut kernel mixture that comes into contact with the movable plate 42 will come into contact with the inner wall of the processing frame 41. Then, the walnut kernel mixture will move vertically downward along the inner wall to the feed inlet 413 and leave from the center of the processing frame 41. Compared with the prior art, the feed inlet 413 of the present invention defines the position where the walnut kernels leave the fixed frame, thereby ensuring that the walnut kernel mixture that leaves one processing frame 41 can be impacted by the movable plate 42 in another processing frame 41.

[0046] See Figure 9As shown: one end of the movable strip 411 can extend into the interior of the processing frame 41, and the movable plate 42 is provided with a long groove 421 that can be inserted into the movable strip 411.

[0047] After prolonged operation, the movable plate 42 may collide with hard materials such as walnut shells multiple times. If slight deformation occurs on the movable plate 42, affecting normal operation, the movable plate 42 can be moved vertically to disengage the movable strip 411 from the long slide groove 421. Then, a new movable plate 42 can be taken out and inserted into the processing frame 41 through the long slide groove 421. Compared with the prior art, the movable plate 42 of the present invention moves synchronously with the movable strip 411 through the long slide groove 421, thereby enabling the movable plate 42 to be replaced quickly and conveniently.

[0048] See Figures 6-7 As shown: the processing frames 41 are all fitted together, and the processing frame 41 and the discharge frame 43 are fitted together.

[0049] When the walnut kernel mixture moves from one processing frame 41 to another, the walnut kernel mixture will not leave the connection point between the two processing frames 41 because the two processing frames 41 are in contact. When the walnut kernel mixture enters the discharge frame 43 from the processing frame 41, the walnut kernel mixture will not leave the connection point between the processing frame 41 and the discharge frame 43 because the discharge frame 43 and the processing frame 41 are in contact. Compared with the prior art, the present invention limits the spacing between processing frames 41 and between processing frames 41 and discharge frame 43, thereby preventing leakage of walnut kernel mixture.

[0050] See Figures 7-8 and Figure 10 As shown: The discharge frame 43 also includes a rotating disk 432. An L-shaped bracket 433 that can rotate the rotating disk 432 is fixedly installed on the discharge frame 43. The rotating disk 432 and the output gear 45 are connected by a bevel gear 434. The axis of the rotating disk 432 is parallel to the transport direction of the conveyor belt 2. An eccentric first fixed shaft 4321 is fixedly installed on the rotating disk 432. A second fixed shaft 435 is fixedly installed on the discharge frame 43. A connecting strip 4312 is fixedly installed on the storage shell 431. A limiting groove 4313 that can slide with the first fixed shaft 4321 is opened on the connecting strip 4312. A round hole 4314 that can be shafted with the second fixed shaft 435 is opened on the connecting strip 4312.

[0051] The output gear 45 causes the rotating disk 432 to rotate via the bevel gear 434. When the rotating disk 432 rotates, the first fixed shaft 4321 slides in the limiting groove 4313, thereby causing the connecting bar 4312 to reciprocate within a certain range around the axis of the second fixed shaft 435. Compared with the prior art, the rotating disk 432, connecting bar 4312 and bevel gear 434 of the present invention cooperate to make the movement of the storage shell 431 controlled by the output gear 45, thereby making the movement of the storage shell 431 consistent with the output gear 45.

[0052] See Figures 1-5 and Figure 7 As shown: An automatic sorting method for walnut shells and kernels, using the aforementioned automatic sorting equipment for walnut shells and kernels, includes the following steps:

[0053] S1. After pressing whole walnuts, a mixture of walnut kernels is obtained. The mixture of walnut kernels is poured into the feed inlet 11.

[0054] S2. The walnut kernels enter the processing frame 41 through the feed inlet 11. At this time, the movable plate 42 in the processing frame 41 is in reciprocating linear motion. While the movable plate 42 is moving, it continuously impacts the walnut kernel mixed raw material, thereby causing the kernels placed inside the walnut shell to leave the walnut shell and the kernels that leave the walnut shell to break.

[0055] S3. The walnut kernel mixture after passing through the processing frame 41 enters the discharge frame 43. The pendulum-shaped storage shell 431 outputs the walnut kernel mixture onto the conveyor belt 2. The walnut kernel mixture is distributed in a sinusoidal curve on the conveyor belt 2.

[0056] S4, the air outlet component 3 blows out air, causing the lighter kernels to move with the air and leave from the first discharge port 12, while the heavier walnut shells leave from the second discharge port 13 along with the conveyor belt 2.

[0057] Compared to the prior art, the processing frame 41 and the movable plate 42 of the present invention cooperate to allow the kernels placed inside the broken walnut shells to leave the broken walnut shells after entering the processing frame 41. The kernels will break into smaller pieces due to impact. The storage shell 431 limits the position of the walnut kernels output to the conveyor belt 2. The conveyor belt 2 and the air outlet assembly 3 cooperate to allow kernels and walnut shells of different weights to leave from the first outlet 12 and the second outlet 13 respectively. This ensures that the weight of the walnut shells and kernels entering the conveyor belt 2 is within a fixed range, avoiding the situation where the kernels and kernels move in the same direction due to similar weights. At the same time, it also ensures that the kernels on the conveyor belt 2 will not come into contact with other walnut shells or kernels and will not pile up and move.

[0058] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
