[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, a walnut shelling and kernel-shell separation device includes a box body 3. The whole walnuts will fall into the box body 3 and then fall downward for shelling, which can prevent a large number of walnuts from being shelled at the same time and reduce the possibility of clogging of the device during shelling. A shelling mechanism 4 for shelling the walnuts is fixedly installed at the lower end of the box body 3. The shell of the walnut can be broken first, and then the shell can be gradually broken open. This shelling method can ensure the completeness of the walnut kernel when the shell is broken.

[0034] Then, there are different shelling methods for different varieties of walnuts to facilitate subsequent separation work. A separation mechanism 5 for separating walnut kernels and walnut shells is fixedly installed at the lower end of the shelling mechanism 4. The weights of the walnut shells and walnut kernels after shelling are different. When the walnut shells and walnut kernels fall freely, they can be better separated by the flow of air.

[0035] Further explanation, in order to better crack the walnut shell, as Figure 3As shown, the shell breaking mechanism 4 includes a shell breaking box 41. The whole walnut will fall from the box body 3 into the shell breaking box 41. A rotating motor 42 is fixedly installed at the rear end of the shell breaking box 41. The output end of the rotating motor 42 passes through the inner cavity of the shell breaking box 41 and is fixedly installed with a threaded roller 43. By starting the rotating motor 42, it drives the threaded roller 43 to rotate. A friction frame 44 adapted to the right side of the threaded roller 43 is provided, and the walnut will definitely fall between the threaded roller 43 and the friction frame 44. Then, the threaded roller 43 rotates to cooperate with the friction frame 44 to crack the walnut.

[0036] Then, the diameters of the roller surfaces between the threaded grooves of the threaded roller 43 are different. Larger walnuts can be shelled at the front side, while smaller walnuts will roll to the back side before being shelled. Two rotating rollers 47 are rotatably installed in the inner cavity of the box body 3. The walnuts that fall into the box body 3 need to pass through the two rotating rollers 47 to break the shells, and then they can be shelled by the threaded roller 43 and the friction frame 44;

[0037] Then, the rotating roller 47 on the left is connected to the threaded roller 43 by a belt, and the two rotating rollers 47 are connected to each other by a belt. When the rotating motor 42 drives the threaded roller 43 to rotate, the threaded roller 43 can drive the two rotating rollers 47 to rotate through the belt.

[0038] Specifically, start the rotating motor 42 to drive the threaded roller 43 to rotate, and the threaded roller 43 can drive the two rotating rollers 47 to rotate at the same time. The rotating rotating roller 47 can crack the walnut shells that fall into the box body 3, which is convenient for subsequent shelling work. When the cracked walnuts fall from the box body 3 into the shell breaking box 41, they will fall between the threaded roller 43 and the friction frame 44. The rotating threaded roller 43 will cooperate with the friction frame 44 to crack the shells. After the shelling is completed, the walnut shells and walnut kernels are separated, the volume will become smaller, and then they will fall between the threaded roller 43 and the friction frame 44 to be separated and then collected.

[0039] Further explanation, in order to crack the shells of different types of walnuts, such as Figure 4 As shown, the friction frame 44 includes a cylinder 441 fixedly mounted on the right end of the shell breaking box 41, the output end of the cylinder 441 passes through the inner cavity of the shell breaking box 41 and is fixedly mounted with an arc block 442, the position of the arc block 442 can be adjusted by starting the cylinder 441, the arc-shaped inner wall of the arc block 442 is provided with a friction roller 443, the arc block 442 can drive the friction roller 443 to move, when the friction roller 443 is close to the threaded roller 43, the walnut shell will be broken faster, which is suitable for thick-shelled walnuts, when the friction roller 443 is away from the threaded roller 43, the walnut shell will be slowly broken into smaller pieces, which is used to process thin-shelled walnuts;

[0040] Then, the connection relationship between the friction roller 443 and the arc block 442 is a movable connection. The friction roller 443 and the front end of the threaded roller 43 are fixedly installed with a connecting rod. The front ends of the two connecting rods are fixedly installed with pulleys 45. A tensioning wheel 46 is provided between the two pulleys 45. A belt is wound between the two pulleys 45 and the tensioning wheel 46. When the threaded roller 43 rotates, the friction roller 443 can be driven to rotate through the pulley 45. The tensioning wheel 46 is a conventional technology. When the friction roller 443 moves, the belt between the pulley 45 and the tensioning wheel 46 is always in a taut state.

[0041] Specifically, different types of walnuts have different shelling methods. When processing thick-shelled walnuts, it is necessary to start cylinder 1 441 to push the arc block 442 and the friction roller 443 to move toward the side close to the threaded roller 43, so that the volume of the walnut shell after shelling is larger. When processing thin-shelled walnuts, it is necessary to start cylinder 1 441 to pull the arc block 442 and the friction roller 443 to move toward the side away from the threaded roller 43, so that the walnut shell is broken into smaller pieces.

[0042] Further explanation, in order to separate the walnut shell and walnut kernel after the shell is broken, as Figure 5 As shown, the separation mechanism 5 includes a separation box 51. The walnut shells and walnut kernels after the shells are broken will fall into the separation box 51. The inner cavity of the separation box 51 is fixedly installed with a cylinder 2 52. The right end of the separation box 51 is provided with two rectangular grooves. Separation fans 53 are fixedly installed in the two rectangular grooves. The separation fans 53 blow the walnut shells and walnut kernels after the shells are broken by the shell breaking mechanism 4. The weights of the walnut shells and walnut kernels are different. When the walnut shells and walnut kernels fall freely, the separation fan 53 will blow the lighter one to the left, and the heavier one will fall directly down.

[0043] Then, rotating plates 54 are rotatably installed on the lower sides of the left and right ends of the separation box 51. The walnut shells after shelling can be collected from one side of the rotating rotating plate 54, and the side of the rotating plate 54 that does not rotate will be used to collect the walnut kernels after shelling. Two inclined plane blocks 55 are provided in the middle of the inner cavity of the separation box 51. The walnut shells or walnut kernels fall on the inclined surfaces of the inclined plane blocks 55 and roll downward without getting stuck in the separation box 51. The two inclined plane blocks 55 are both provided on the lower side between the threaded roller 43 and the friction roller 443, and are positioned to the left. The walnut shells and walnut kernels will fall to the right side of the inclined plane block 55, and the lighter side will be blown to the left side of the inclined plane block 55 by the separation fan 53, thereby realizing the separation of walnut shells and walnut kernels. An adjusting mechanism 56 is provided on the lower side of the inclined plane block 55.

[0044] Specifically, the walnut shells and walnut kernels after shelling will fall into the separation box 51 and freely fall on the right side of the inclined block 55. During the free fall, the separation fan 53 will blow the walnut shells and walnut kernels, and the lighter ones will be blown to the left side of the inclined block 55 by the separation fan 53, completing the separation of the walnut shells and walnut kernels. The switches of the rotating plates 54 on both sides can be controlled by the adjustment mechanism 56. The walnut shells produced after shelling will fall from the rotating plates 54, and the walnut kernels will fall from the separation box 51 for collection.

[0045] Further explanation, in order to facilitate the separation of different types of walnut shells and walnut kernels, such as Figure 6 As shown, the adjustment mechanism 56 includes a support shell 561, and a movable plate 562 is slidably mounted on the inner wall of the lower side of the support shell 561. The output end of the second cylinder 52 is connected to the movable plate 562. By starting the second cylinder 52, it pushes the movable plate 562 to move left and right. When processing thick-shelled walnuts, the walnut shell is heavier than the walnut kernel, and the movable plate 562 will be on the right. When processing thin-shelled walnuts, the walnut shell is lighter than the walnut kernel, and the movable plate 562 will be on the left.

[0046] Then, rolling plates 563 are fixedly installed on both ends of the movable plate 562. When the movable plate 562 is on that side, the rolling plate 563 will block the outlet of the separation box 51 on that side, so that the walnut shells cannot fall down. Then, they roll toward the side of the rotating plate 54 through the inclined surface of the rolling plate 563, and finally roll down from the rotating plate 54 and are collected. A number of L-shaped plates 564 are fixedly installed on the upper ends of the two rolling plates 563. The L-shaped plates 564 will move with the rolling plates 563, and when they contact the rotating plate 54, they will push the rotating plate 54 to rotate.

[0047] Specifically, when processing thin-shelled walnuts, start cylinder 2 52 to drive the movable plate 562 and the rolling plate 563 to move to the left, and the rolling plate 563 will drive the L-shaped plate 564 to move. When the L-shaped plate 564 on the left side contacts the rotating plate 54, it will push the rotating plate 54 to rotate, and the lighter walnut shells will roll down from the inclined surface of the L-shaped plate 564 and then be collected by the rotating plate 54, and the heavier walnut kernels will fall directly downward. When processing thick-shelled walnuts, start cylinder 2 52 to drive the movable plate 562 and the rolling plate 563 to move to the right, push the rotating plate 54 on the right, and the heavier walnut shells will roll down from the rotating plate 54 on the right, while the lighter walnut kernels will fall directly.

[0048] The specific implementation of this embodiment is as follows: start the rotating motor 42, so that it drives the threaded roller 43 to rotate, and the threaded roller 43 can drive the two rotating rollers 47 to rotate at the same time. The rotating rotating rollers 47 can crack the walnut shells that fall into the box body 3, which is convenient for the subsequent shelling work. When the cracked walnuts fall from the box body 3 into the shell breaking box 41, they will fall between the threaded roller 43 and the friction frame 44. The rotating threaded roller 43 will cooperate with the friction frame 44 to crack the shells. After the shelling is completed, the walnut shells and walnut kernels are separated, the volume will become smaller, and then they will fall between the threaded roller 43 and the friction frame 44 to be separated and then collected;

[0049] When processing thin-shelled walnuts, it is necessary to start cylinder 1 441 to pull the arc block 442 and the friction roller 443 toward the side away from the threaded roller 43 to break the walnut shell into smaller pieces. Then, start cylinder 2 52 to drive the moving plate 562 and the rolling plate 563 to move to the left. The rolling plate 563 will drive the L-shaped plate 564 to move. When the L-shaped plate 564 on the left side contacts the rotating plate 54, it will push the rotating plate 54 on the left side to rotate.

[0050] The cracked walnut shells and walnut kernels fall into the separation box 51 and freely fall on the right side of the inclined block 55. During the free fall, the separation fan 53 blows the walnut shells and walnut kernels. The lighter walnut shells will be blown to the left side of the inclined block 55 by the separation fan 53. The walnut shells will roll down the inclined surface of the L-shaped plate 564 and then be collected by the rotating plate 54 on the left. The heavier walnut kernels will fall directly downwards.

[0051] When processing thick-shelled walnuts, it is necessary to start the cylinder 1 441 to push the arc block 442 and the friction roller 443 to move to the side close to the threaded roller 43, so that the volume of the walnut shell after the shell is broken is larger. Then, start the cylinder 2 52 to drive the moving plate 562 and the rolling plate 563 to move to the right, pushing the rotating plate 54 on the right side to rotate it.

[0052] The broken walnut shells and walnut kernels will fall into the separation box 51 and freely fall on the right side of the inclined block 55. During the free fall, the separation fan 53 will blow the walnut shells and walnut kernels. The lighter walnut kernels will be blown to the left side of the inclined block 55 by the separation fan 53. The walnut kernels will roll down the inclined surface of the inclined block 55 and then fall directly downward for collection, while the heavier walnut kernels will fall directly downward and be collected by the rotating plate 54 on the right.

[0053] Example 2

[0054] This embodiment provides a walnut processing production line based on the first embodiment, in which the walnut shelling and kernel-shell separation equipment in the first embodiment is installed and used in conjunction with the equipment to achieve the purpose of walnut kernel processing on the production line.

[0055] Further explanation, in order to facilitate the transportation of walnuts and walnut kernels after shelling, as Figure 1 As shown, a screening device 2 for screening walnuts by size is fixedly installed on the upper end of the box 3, which can screen out larger walnuts to prevent blockage during shelling. A loading conveyor belt 1 for loading walnuts is provided on the upper side of the screening device 2. The complete walnuts are transported to the upper side of the screening device 2 through the loading conveyor belt 1. A unloading conveyor belt 6 for transporting the walnut kernels after shelling is provided on the lower side of the separation mechanism 5. The walnut kernels after shelling and separation will fall onto the unloading conveyor belt 6 and then be collected.

[0056] Further explanation, in order to prevent the shell breaking mechanism 4 from being blocked, as shown in FIG. Figure 8 As shown, the screening device 2 includes a tank body 21, and two curved plates 22 are fixedly installed on the inner wall of the tank body 21. When the complete walnuts enter the curved plates 22, they will be scattered by the two curved plates 22, so that the walnuts will not gather together, which is convenient for subsequent screening work. A support frame 23 is fixedly installed in the inner cavity of the tank body 21, and a vibration motor 24 is fixedly installed on the upper end of the support frame 23. The vibration motor 24 is supported by the support frame 23, and the vibration motor 24 is a prior art. The screening function is achieved by the vibration of the vibration motor 24.

[0057] Then, a screening plate 25 is fixedly installed at the output end of the vibration motor 24. The opening of the screening plate 25 can screen out larger walnuts, which are driven to shake by the vibration motor 24, not only allowing smaller walnuts to fall from the screening plate 25, but also preventing larger walnuts from blocking the opening on the screening plate 25. An arc-shaped hole is provided on the front side of the arc-shaped surface of the tank body 21, and the larger walnuts will leave the tank body 21 through the arc-shaped hole. A material receiving box 26 fixedly installed on the surface of the tank body 21 is provided on the front side of the arc-shaped hole. The larger walnuts will roll into the material receiving box 26 and be collected. A discharge pipe 27 is fixedly installed at the lower end of the tank body 21. The discharge pipe 27 is connected to the box body 3, and the walnuts of the appropriate size will enter the box body 3 from the tank body 21 through the discharge pipe 27.

[0058] The specific implementation of this embodiment is as follows: the loading conveyor belt 1 and the unloading conveyor belt 6, the loading conveyor belt 1 will move the complete walnuts to the upper side of the screening device 2, and then fall into the tank body 21. When the walnuts touch the curved plate 22, they will roll and disperse around, which is convenient for subsequent screening. Finally, the walnuts will roll on the tank body 21 and fall on the upper end of the screening plate 25. The vibration motor 24 is started to drive the screening plate 25 to shake, which can allow smaller walnuts to fall from the screening plate 25 and prevent larger walnuts from blocking the opening on the screening plate 25, thus realizing the screening of walnuts, and the larger walnuts will roll on the upper end of the screening plate 25, leave the tank body 21 from the curved hole and then fall into the receiving box 26 for collection. Walnuts that meet the size will enter the box body 3 from the tank body 21 through the discharge pipe 27.

[0059] It should be noted that the specific installation methods, circuit connection methods and control methods of the loading conveyor belt 1, the unloading conveyor belt 6, the vibration motor 24, the rotating motor 42, the cylinder 1 441, the cylinder 2 52 and the separation fan 53 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
