Description

Technical Field

[0001] The invention relates to the technical field of forest fruit processing, and more specifically to a variable-gap cutting shovel type green walnut dry peeling machine. Background Art

[0002] Walnut is a plant of the Juglandaceae family. It is rich in nutrients and is one of the world's famous "four major dried fruits". Walnut fruit is mainly composed of an outer green skin, a middle hard shell and an inner kernel. With the annual increase in walnut production, walnut peeling is very important for the later processing and utilization of walnuts. If the green skin of harvested green walnuts is not peeled off in time, it will affect the color of the kernel, causing the kernel to mold and black spots to appear on the surface of the walnut hard shell, which directly affects the commodity value and market competitiveness of walnuts.

[0003] At present, the main method for peeling green walnuts is mechanical peeling, but most of the existing green walnut peeling equipment has some problems. First, in the process of peeling green walnuts, the peeled green skin is often in a crumbly state, which is not conducive to the recycling and reuse of the green skin and causes harm to the environment. Secondly, the versatility is poor, and only green walnuts with a small size range can be peeled. When it comes to peeling green walnuts with a large size range of multiple varieties, there are problems of low peeling rate and high breakage rate. Third, the work efficiency is low. Many existing green walnut peeling equipment can only process green walnuts in batches. It is necessary to wait until a batch of green walnuts is completely processed before the next batch can be processed, which reduces the work efficiency. In order to recycle the green skin, protect the environment, and improve the efficiency and versatility of green walnut peeling equipment, it is necessary to address these shortcomings in green walnut peeling equipment.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention is powered by a power transmission mechanism, and uses a material lifting mechanism and a pressing and cutting mechanism to achieve preliminary squeezing and cutting of the graded green-skinned walnuts during the material lifting process, and uses a scraping mechanism to squeeze and scrape the green-skinned walnuts to separate the green skin from the nuts. The overall structure is simple, the function is reliable and easy to implement, and it has good versatility and extremely high efficiency.

[0020] (2) The present invention aims at the characteristics of uneven size and different thickness of green-skinned walnuts, especially the characteristics that different varieties of green-skinned walnuts have large differences in size and peeling characteristics. The green-skinned walnuts are first graded using existing equipment, and extrusion gaps of different sizes are formed between the inclined plate and the material lifting mechanism on the pressing and cutting mechanism, so that the green-skinned walnuts of different sizes after classification can be initially squeezed and cut.

DETAILED DESCRIPTION

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figure 1 As shown, the present invention provides a variable gap cutting shovel type green walnut dry peeling machine, which includes a frame 10, a power transmission mechanism 20 arranged on the frame 10, a pressing mechanism 30, a material lifting mechanism 40, a shoveling mechanism 50 and a material receiving mechanism 60;

[0034] The power transmission mechanism 20 provides power to the material lifting mechanism 40 and the scraping mechanism 50 respectively; the material lifting mechanism 40 is used to lift the green-skinned walnuts after external grading and convey them to the scraping mechanism 50; the pressing and cutting mechanism 30 cooperates with the material lifting mechanism 40 to complete variable gap extrusion cutting of the green walnuts during the lifting process; the scraping mechanism 50 is used to squeeze and scrape the green-skinned walnuts after pressing and cutting, and the extrusion and scraping gap can be changed by adjustment, so as to separate the walnut green skin and the walnut nut; the material collecting mechanism 60 is used to collect the separated walnut nut and walnut green skin.

[0035] The present invention is powered by a power transmission mechanism 20, and the green-skinned walnuts are lifted by a material lifting mechanism 40. Under the variable gap extrusion cutting of the pressing and cutting mechanism 30 and the extrusion and shoveling of the shoveling mechanism 50, the green-skinned walnuts can be subjected to variable gap extrusion cutting and shoveling without adding water, so that the green skin can be separated into blocks. The present invention has a wide range of adaptability to green-skinned walnuts of different sizes, greatly reduces the breakage rate of walnuts, and ensures the peeling effect.

[0036] As attached Figure 2 As shown, the material lifting mechanism 40 includes a chain plate 41 and a baffle 42. The chain plate 41 is arranged on the frame 10 and connected to the power transmission mechanism 20. The baffles 42 are evenly arranged on the chain plate 41 to block the green-skinned walnuts.

[0037] In this embodiment, the graded green-skinned walnuts fall onto the chain plate 41 of the material lifting mechanism 40, and the chain plate 41 can be driven from bottom to top under the driving action of the power transmission mechanism 20, and the green-skinned walnuts are driven to perform lifting movement through the chain plate 41. The baffle 42 is used to prevent the green-skinned walnuts from sliding during the lifting process. Specifically, the height of the baffle 42 is 30 mm, and the horizontal diameter and side diameter of the green-skinned walnuts are less than 60 mm, so it can be ensured that during the lifting process, the baffle 42 can block the green-skinned walnuts from falling.

[0038] As attached Figure 3 As shown, the cutting mechanism 30 includes an inclined plate 31, a compression rod 32, a rubber groove plate 33 and a variable blade knife group 34. The inclined plate 31 is connected to the frame 10 through the compression rod 32. A cutting gap is formed between the inclined plate 31 and the chain plate 41 of the material lifting mechanism 40. The variable blade knife group 34 and the rubber groove plate 33 are arranged on the lower surface of the inclined plate 31 and correspond to the position of the cutting gap.

[0039] Furthermore, four groups of variable blade knife groups 34 are provided, and two groups are provided on both sides of the rubber groove plate 33. The center lines of each group of variable blade knife groups 34 do not overlap each other, so that adjacent variable blade knife groups 34 are misaligned, thus ensuring that different variable blade knife groups 34 can cut different positions of the green-skinned walnuts.

[0040] Furthermore, five groups of compression rods 32 are respectively arranged at opposite ends of the inclined plate 31, and each group of compression rods 32 respectively corresponds to the position of the variable blade group 34 and the rubber groove plate 33, so as to ensure the overall rebound effect of the inclined plate 31. In this embodiment, two compression rods 32 are used in each group, and are located at the two ends of the corresponding variable blade group 34 and the rubber groove plate 33, and the number of groups and the number of each group can be adjusted according to actual needs.

[0041] Specifically, the compression rod 32 includes a connecting screw 321 and a compression spring 322 mounted on the connecting screw 321, and the connecting screw 321 connects the tilting plate 31 and the frame 10. The height difference of the compression springs 322 on the compression rod 32 at the corresponding two ends of the tilting plate 31 is 25 mm, so that the inclination of the tilting plate 31 can be ensured.

[0042] In this embodiment, the effective width of the inclined plate 31 is 480 mm. When the compression rod 32 is not working, a 40-65 mm cutting gap is formed between the inclined plate 31 and the material lifting mechanism 40. The inclined plate 31 and the chain plate 41 are both inclined and tilted in the horizontal direction to form a gradually changing cutting gap, which is used to process green-skinned walnuts of corresponding sizes. The number of the compression rod 32 and the variable blade set 34 can be adjusted according to actual needs to ensure the reliability of the overall operation of the cutting mechanism 30.

[0043] In this embodiment, when the material lifting mechanism 40 drives the green-skinned walnuts to be lifted and enter the pressure-cutting gap, they are squeezed and cut under the action of the variable-edge knife group 34. When passing through the rubber groove plate 33, the green-skinned walnuts are rotated under the action of the pressure of the rubber groove plate 33. Therefore, the variable-edge knife groups 34 on the front and rear sides of the rubber groove plate 33 can cut different surfaces of the green-skinned walnuts.

[0044] In this embodiment, the pressure cutting mechanism 30 is provided with multiple groups of variable blade knife groups 34 and rubber groove plates 33. After a group of variable blade knife groups 34 completes cutting, the rubber groove plates 33 squeeze the green-skinned walnuts in cooperation with the material lifting mechanism 40, which can cause the green-skinned walnuts to rotate to a certain extent, and the center lines of different variable blade knife groups 34 do not overlap each other, which ensures that different groups of variable blade knife groups 34 have different cutting positions for green-skinned walnuts. Connected by the compression rod 32, when the inclined plate 31 is subjected to a large force, it can move upward, which can increase the pressure cutting gap, and again avoid damage to the walnut nuts due to excessive pressure.

[0045] As attached Figure 4 As shown, the variable blade set 34 includes a variable blade 341, a toothed baffle 342 and a connecting screw 343. The tail of the variable blade 341 is connected to the inclined plate 31 through the connecting screw 343. The blade of the variable blade 341 corresponds to the material lifting mechanism 40, which is convenient for acting on walnuts. The toothed baffle 342 is arranged at the tail of the variable blade 341 and inserted into the inclined plate 31 through a toothed structure, and is used to block the tail end of the variable blade 341, so as to prevent the variable blade 341 from rotating during operation.

[0046] Furthermore, the variable-edge blade 341 is a pointed blade, that is, the head is a pointed angle, and the thickness of the blade gradually increases from the head to the tail. While cutting the green-skinned walnuts, it can give the walnut green skin an opening force along the direction of increasing thickness of the variable-edge blade 341, causing part of the green skin to crack and fall off.

[0047] In this embodiment, each variable-edge knife set 34 includes 17 variable-edge blades 341, and the distance between two adjacent variable-edge blades 341 is 25 mm, so a green-skinned walnut can be cut by at least two variable-edge blades 341. The length of the variable-edge blade 341 is 36 mm, and the maximum thickness is 8 mm. The number of the variable-edge blades 341 can also be adjusted according to actual needs to ensure the reliability of the variable-edge knife set 34.

[0048] As attached Figure 5 and Figure 6 As shown, the scraping mechanism 50 includes a material protection hopper 51, a squeeze plate 54 and a conical rubber roller 59 respectively arranged on the frame 10, and the conical rubber roller 59 is connected to the power transmission mechanism 20 and can rotate. The squeeze plate 54 corresponds to the surface position of the conical rubber roller 59, and forms different squeeze and scrape gaps. The material protection hopper 51 is located above the conical rubber roller 59 and the squeeze plate 54, and the open end corresponds to the position of the squeeze and scrape gap. The squeeze plate 54 is provided with a scraping knife group 55 corresponding to the position of the squeeze and scrape gap, and the scraping knife group 55 is used to scrape the green-skinned walnuts that fall into the squeeze and scrape gap.

[0049] Furthermore, at least two groups of extrusion plates 54 are arranged in parallel along the axial direction on the surface of the conical rubber roller 59, and the adjustment range of the extrusion and scraping gap formed by the extrusion plate 54 and the conical rubber roller 59 is 26 to 49 mm, which can meet the size range of all walnut nuts. At least two groups of scraping knife groups 55 are arranged on the extrusion plate 54 along the movement direction of the green-skinned walnuts in the extrusion and scraping gap, which are used to reliably scrape the green-skinned walnuts. Specifically, the extrusion plate 54 is provided with 5 groups, and the scraping knife group 55 is provided with 10 groups, and the number of the two can be adjusted according to actual needs.

[0050] Furthermore, a material dividing hinge 53 is arranged in parallel in the material protection hopper 51, and a material dividing plate 52 is arranged on the inner wall opposite to the material dividing hinge 53; the material dividing plate 52 corresponds to the side position of the material dividing hinge 53, and both are respectively connected to the corresponding extrusion plates 54. The material dividing hinge 53 can prevent green walnuts from falling into the gap between adjacent extrusion plates 54, and the material dividing plate 52 can prevent green walnuts from falling into the gap between the upper ends of the extrusion plates 54 at both ends and the material protection hopper 51, thereby ensuring the reliability of the scraping mechanism 50.

[0051] Specifically, the material dividing plate 52 is made of a rubber plate, which is simple, reliable and easy to install. The number of the material dividing hinges 53 is adjusted according to the number of the extrusion plates 54 to ensure that the green walnuts in the material protection hopper 51 can fall into the extrusion and scraping gap.

[0052] In this embodiment, the material protection hopper 51 is located above the extrusion plate 54 and the conical rubber roller 59, and together with the material dividing plate 52 and the material dividing hinge 53, ensures that the green-skinned walnuts can smoothly enter the working area, that is, the extrusion and scraping gap, and can also prevent the green-skinned walnuts from directly sliding out along the clockwise rotation direction of the conical rubber roller 59. The extrusion and scraping gap formed between the top of each group of the extrusion plates 54 and the conical rubber roller 59 is large, which is convenient for the green-skinned walnuts to enter smoothly.

[0053] Furthermore, the conical rubber roller 59 includes a rubber roller shaft 591, a metal plate 592, a rubber roller body 593 and a rubber layer 594, and the rubber roller body 593 is connected to the frame 10 through the rubber roller shaft 591. The outer surface of the rubber roller body 593 is provided with a rubber layer 594, and the two end surfaces are provided with metal plates 592. The rubber roller body 593 is a conical structure, and the surface is provided with a rubber layer 594, and the surface of the rubber layer 594 is provided with a notch, so as to increase the friction between the conical rubber roller 59 and the green-skinned walnut, and prevent the green-skinned walnut from being stuck.

[0054] In the present embodiment, a conical rubber roller 59 is used. Since a rubber layer 594 is provided on the rubber roller body 593, when the rubber roller body 593 rotates and squeezes the green-shelled walnuts between the extrusion plate 54, the extrusion force is too large and the rubber layer 594 will be compressed to a certain extent, thereby protecting the walnut nuts from damage. That is, during the scraping process, the rubber layer 594 is compressed to protect the walnut nuts and ensure the peeling effect. The structure is simple and the function is reliable.

[0055] Furthermore, the extrusion plate 54 is connected to the frame 10 by an adjusting screw 56, and there is a certain gap between adjacent extrusion plates 54. By moving the position of the adjusting screw 56 on the frame 10, the position of the extrusion plate 54 can be adjusted, thereby changing the extrusion and scraping gap formed by the extrusion plate 54 and the conical rubber roller 59. When the position of the extrusion plate 54 changes, since the material separation hinge 53 and the material separation plate 52 are both made of rubber plates and connected to the corresponding extrusion plate 54 and the material protection hopper 51, the two will adjust their positions adaptively to prevent the green-skinned walnuts from falling into the non-working area. Further, a separation column 57 is set below the extrusion plate 54 and at the end of the extrusion and scraping gap, and a guide plate 58 is set below the separation column 57. The peeled green skin and walnut nuts can be separated by the separation column 57, and the green skin directly falls in the gap between the adjacent separation columns 57, and the walnut nuts will slide through the separation column 57 to the guide plate 58.

[0056] As attached Figure 7 As shown, the scraping blade assembly 55 includes a scraping blade 551 , a connecting boss 552 , a positioning block 553 , a bidirectional spring 554 , a positioning pin shaft 555 , a cotter pin 556 and a limit block 557 .

[0057] The end of the connecting boss 552 is provided with a scraping blade 55. The connecting boss 552 is fixedly connected to the mounting extrusion plate 54 through a positioning block 553. The connecting boss 552 and the positioning block 553 are connected through a positioning pin 555, so that the scraping blade 551 can be preliminarily positioned. The positioning pin 555 is provided with a cotter pin 556. The positioning block 553 is provided with a limit block 557 corresponding to the position of the cotter pin 556. The limit block 557 limits the rotation of the cotter pin 556 to limit the position of the scraping blade 551. A bidirectional spring 554 is provided between the connecting boss 552 and the surface opposite to the extrusion plate 54.

[0058] Furthermore, the scraping blade 551 includes a connecting plate and a blade arranged on the connecting plate. The blades are arranged in three parallel rows, and the blades are arc blocks with blade edges and pointed ends. Specifically, the connecting plate is a rectangular thin plate, and the blade in the middle of the three blades has a larger arc diameter than the blades at the two ends. The scraping blade 551 fits the shape characteristics of the walnut and can more effectively scrape off all the green skin on the surface of the walnut.

[0059] In this embodiment, the scraping blade 551 is not in direct contact with the extrusion plate 54, and there is a certain gap between the two to facilitate the rotation of the scraping blade 551. When the green-skinned walnut is squeezed by the conical rubber roller 59 and passes through the scraping blade 551, the scraping blade 551 scrapes into the green skin, and the green-skinned walnut continues to be squeezed and moves downward, driving the scraping blade 551 to rotate. After rotating to a certain position, the scraping blade 551 is reset under the action of the bidirectional spring 554 to complete the scraping. After multiple scrapings, the green skin of the green-skinned walnut is separated from the walnut nut.

[0060] Furthermore, the material collecting mechanism 60 includes a nut collecting basket 61 and a green peel collecting basket 62. The nut collecting basket 61 corresponds to the position of the material guide plate 58, and the green peel collecting basket 62 corresponds to the position of the separation column 57, so as to facilitate the collection of the separated nuts and green peels.

[0061] The variable gap cutting shovel type green walnut dry peeling machine provided by the present invention has the following working process:

[0062] The graded green-skinned walnuts fall onto the chain plate 41 of the material lifting mechanism 40, are lifted, and move to the pressing and cutting mechanism 30. Since pressing and cutting gaps of different sizes are formed between the inclined plate 31 on the pressing and cutting mechanism 30 and the material lifting mechanism 40, the graded green-skinned walnuts enter the different pressing and cutting gaps in order according to their sizes.

[0063] First, two groups of variable blade knife groups 34 cut the corresponding green-skinned walnuts. Under the joint action of the rubber groove plate 33 and the baffle plate 42 of the material lifting mechanism 40, the green-skinned walnuts are subjected to extrusion force and rotate to a certain extent. Then, the two groups of variable blade knife groups 34 cut the rotated green-skinned walnuts. This ensures that the surfaces of the green-skinned walnuts cut by the front and rear groups of variable blade knife groups 34 are not the same surface, and the center lines of the variable blade knife groups 34 do not overlap, ensuring different cutting positions. When the inclined plate 31 is subjected to a large reverse pressure from the green-skinned walnuts, the inclined plate 31 will move up under the action of the compression rod 32 to achieve a change in the gap and ensure that the walnuts are not damaged.

[0064] After being pressed and cut, the graded green-skinned walnuts continue to enter the material hopper 51 of the scraping mechanism 50 under the lifting action of the material lifting mechanism 40. Under the action of the material dividing rubber 52 and the material dividing hinge 53, they enter the extrusion scraping gaps of different sizes formed by the extrusion plate 54 and the conical roller 59 according to the size and position after the initial classification. The material hopper 51 can prevent the green-skinned walnuts from directly rolling out of the scraping area. By moving the adjustment screw 56, the extrusion plate 54 can be moved along the axial direction of the conical rubber roller 59, so that the extrusion scraping gap changes. Through the action of the scraping knife group 55 on the extrusion plate 54, the green skin on the surface of the walnut falling into the extrusion scraping gap can be scraped off. After scraping, the green skin of the walnut is separated from the walnut nut under the action of the separation column 57, and the green skin directly falls into the green skin collection basket 62. The walnut nut slides to the guide plate 58 and then falls into the nut collection basket 61.

[0065] The present invention can press and scrape the graded green-skinned walnuts to make the green skin of the walnuts fall off, and can separate the green skin into blocks to facilitate environmental protection and green skin recovery. By setting different pressing and scraping gaps and extrusion and scraping gaps, under the action of the compression rod and the elastic part, it has a wide adaptability to green-skinned walnuts of different varieties or sizes, greatly reducing the breakage rate of walnuts.

[0066] The invention aims at the characteristic that the green-peeled walnut has recycling value, does not need to add water for treatment during the working process, and the separated green peel is in block shape, thereby ensuring the convenience of recycling the green peel.

[0067] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
