Description
Technical Field
[0001] The present invention relates to the technical field of screening and shelling of wild peach kernels, and specifically, to a shelling device for wild peach kernels with hierarchical screening. Background Art
[0002] Wild peach kernels are all treasures: the kernels are rich in nutrients and various trace elements needed by the human body. They not only have a good health care effect on the human body but also prevent various diseases. With the continuous increase in the output of wild peach kernels and market demand, the deep processing of wild peach kernels has become an increasingly prominent problem in scientific research and production.
[0003] Currently, for the existing shelling device for wild peach kernels with hierarchical screening, wild peach kernels are usually introduced into the inside of a screening barrel. By using the rotational centrifugal force of the screening barrel, wild peach kernels of different diameters fall through different-diameter screening holes opened on the surface of the screening barrel and finally fall into the inside of the shelling device for shelling and crushing the screened wild peach kernels. However, since the diameters of wild peach kernels are different, it cannot be guaranteed that each wild peach kernel will fall through the screening holes of different diameters. There will be some wild peach kernels whose diameters are similar to the aperture sizes of the screening holes, which easily causes some wild peach kernels to get stuck on the surface of the screening holes and requires manual removal of the wild peach kernels stuck in the screening holes, thus affecting the subsequent screening work of other wild peach kernels and causing blockage problems.
[0004] Therefore, there is an urgent need for a shelling device for wild peach kernels with hierarchical screening to solve the problems of the existing technology. Summary of the Invention
[0005] The purpose of the present invention is to provide a shelling device for wild peach kernels with hierarchical screening to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present invention aims to provide a shelling group for wild peach kernels with hierarchical screening, including a screening mechanism, side plates, and a shelling group;
[0007] The screening mechanism includes screening barrels. There are three screening barrels in total, which are arranged in parallel. The surfaces of the three screening barrels are all provided with screening holes, and the opening diameters of the screening holes gradually increase from left to right. One side of the surface of the leftmost screening barrel is fixedly connected with a mounting plate, and one side of the surface of the mounting plate is fixedly connected with a feeding barrel;
[0008] The side plates are fixedly installed on the back of the guiding plate. The upper end of the side of the side plates is fixedly installed with a fixing plate. An extrusion block is arranged on the surface of the fixing plate, and the position of the extrusion block corresponds to the surface of the screening holes. When the three screening barrels rotate, some wild peach kernels will be stuck in the screening holes and come into contact with and be extruded by the extrusion block, causing the wild peach kernels stuck in the screening holes to fall off and continue to roll as the three screening barrels rotate;
[0009] The shelling group includes stirring rods. There are two stirring rods in total, and the two stirring rods are symmetrically distributed inside the shelling group. The inside of the shelling group is correspondingly connected to the guide plate. The shelled wild peach kernels after sieving fall into the inside of the shelling group through the guide plate, and the shelling treatment of the shelled wild peach kernels after sieving is carried out by the rotation of the stirring rods.
[0010] As a further improvement of this technical solution, kits are movably installed on both sides of the surface of the sieving barrel. A fixing frame is fixedly installed on the surface of the kit. A driving shaft is rotatably installed at the center position of the surface of the fixing frame. One side of the surface of the driving shaft is fixedly connected to a first driving motor. Support legs are fixedly installed below the guide plate. Guide plates are fixedly installed below the three sieving barrels. Partition plates are fixedly installed at both ends of the side of the guide plate.
[0011] As a further improvement of this technical solution, a rotating rod is fixedly connected to one side of the surface of the driving shaft. The rotating rod and the three sieving barrels share the same center of the circle. By starting the first driving motor, the driving shaft and the rotating rod are driven to rotate, so that the three sieving barrels operate synchronously.
[0012] As a further improvement of this technical solution, there are also three guide plates. The three guide plates are distributed in an inclined shape directly below the three sieving barrels, and the three guide plates and the three sieving barrels are vertically corresponding through the partition plates.
[0013] As a further improvement of this technical solution, a baffle is fixedly connected to the bottom of the fixing plate. The baffle is in an arc shape. The length of the baffle matches the length of the three sieving barrels, and it is distributed on the back of the sieving barrel, and the bottom is correspondingly connected to the upper part of the guide plate.
[0014] As a further improvement of this technical solution, a discharge port is opened at the bottom of the front end of the shelling group. A cover plate is fixedly installed above the shelling group. A second driving motor is fixedly installed on the side of the shelling group. A connecting plate is fixedly installed inside the shelling group.
[0015] As a further improvement of this technical solution, a through groove is opened at a position on one side of the cover plate close to the guide plate. The inside of the shelling group is correspondingly connected to the guide plate through the through groove, and the shelled wild peach kernels after sieving are transported into the inside of the shelling group.
[0016] As a further improvement of this technical solution, the connecting plate divides the inside of the shelling group into three parts. The stirring rods rotate inside the shelling group through the second driving motor, and the shelling and crushing treatment of the wild peach kernels transported by the through groove and the guide plate is carried out.
[0017] As a further improvement of this technical solution, the extrusion blocks are evenly distributed at a position above the back of the sieving barrel, and the size of the extrusion blocks matches the diameter size of the sieve holes.
[0018] Compared with the prior art, the beneficial effects of the present invention:
[0019] In the shelling device for the graded and screened wild peach pit shells, since there are wild peach pits with a diameter similar to that of the screening holes, they will get stuck on the surface of the screening holes and keep rotating with the screening barrel, affecting the subsequent screening efficiency of the wild peach pits. By arranging the extrusion blocks to contact the surface of the wild peach pits stuck on the screening holes and using the extrusion force, the wild peach pits are extruded from the surface of the screening holes, ensuring the normal screening operation of the wild peach pits in the subsequent process and avoiding the problem of blockage.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts belong to the scope of protection of the present invention.
[0033] Please refer to Figure 1 - Figure 8 As shown in the figure, the purpose of this embodiment is to provide a hierarchical screening device for shelling peach kernels, which includes a screening mechanism 100, side plates 200 and a shelling group 300;
[0034] The screening mechanism 100 includes a screening barrel 105. There are three screening barrels 105 in total. The three screening barrels 105 are arranged in parallel, and screening holes 106 are formed on the surfaces of the three screening barrels 105. The opening diameters of the screening holes 106 gradually increase from left to right. One side of the surface of the leftmost screening barrel 105 is fixedly connected with a mounting plate 103, and one side of the surface of the mounting plate 103 is fixedly connected with a feeding barrel 104;
[0035] The side plates 200 are fixedly installed on the back of the guide plate 101. The upper end of the side of the side plates 200 is fixedly installed with a fixing plate 201. An extrusion block 203 is arranged on the surface of the fixing plate 201. The extrusion block 203 corresponds to the position of the surface of the screening hole 106. When the three screening barrels 105 rotate, some peach kernels will be stuck in the screening holes 106. When the screening barrels 105 continue to rotate, the extrusion block 203 enters the screening holes 106 and contacts and extrudes the part of the peach kernels stuck in the screening holes 106, so that the peach kernels stuck in the screening holes 106 fall off and continue to roll as the three screening barrels 105 rotate;
[0036] The shelling group 300 includes stirring rods 304. There are two stirring rods 304 in total. The two stirring rods 304 are symmetrically distributed inside the shelling group 300. The inside of the shelling group 300 is correspondingly communicated with the guide plate 101. The screened peach kernels fall into the inside of the shelling group 300 through the guide plate 101, and the screened peach kernels are shelled by the rotation of the stirring rods 304;
[0037] It should be noted that: there are three screening barrels 105 in total. Screening holes 106 are formed on the surfaces of the three screening barrels 105, and the diameters of the screening holes 106 increase from left to right;
[0038] By starting the first drive motor 107, the drive shaft 108 drives the sieve barrel 105 to rotate. Pour the wild peach pits into the feed barrel 104. With the centrifugal force generated by the rotation of the sieve barrel 105, the wild peach pits roll inside the sieve barrel 105. First, the wild peach pits with smaller diameters are screened out from the leftmost part of the sieve barrel 105. Then, the wild peach pits with larger diameters are screened out from the middle part of the sieve barrel 105 in turn. Finally, the wild peach pits with the largest diameters are screened out from the rightmost part of the sieve barrel 105. And during the screening process of wild peach pits with different diameters, some wild peach pits will be stuck on the surface of the sieve holes 106 because they match the diameter of the sieve holes 106. In the long run, it will affect the screening work efficiency of other wild peach pits in the future;
[0039] When some wild peach pits are stuck at the position of the sieve holes 106, they will rotate synchronously with the sieve barrel 105. When the sieve holes 106 with wild peach pits stuck rotate to the top position with the sieve barrel 105, they will contact and be squeezed by the extrusion block 203. Using the downward acting force generated by the contact extrusion, the wild peach pits can be effectively extruded from the surface of the sieve holes 106.
[0040] Therefore, on the basis of the above structure, combined with Figure 1 - Figure 2 As shown, the structure of the screening mechanism 100 is further disclosed. On both sides of the surface of the sieve barrel 105, there are movably installed kits 109. On the surface of the kits 109, there are fixedly installed fixing frames 110. At the central position of the surface of the fixing frames 110, there is a rotatably installed drive shaft 108. On one side of the surface of the drive shaft 108, there is a fixedly connected first drive motor 107. Below the guide plate 101, there are fixedly installed support legs 111. Below the three sieve barrels 105, there is a fixedly installed guide plate 101. At both ends of the side surface of the guide plate 101, there are fixedly installed partition plates 102;
[0041] Furthermore, by starting the first drive motor 107, the drive shaft 108 rotates. Since a rotating rod is connected to the central position inside the sieve barrel 105, one end of the rotating rod is fixedly connected to the drive shaft 108, and the installed kits 109 movably install the sieve barrel 105 above the guide plate 101. Therefore, the sieve barrel 105 can be kept in a rotating state above the guide plate 101;
[0042] The sieve barrel 105 rotates to screen the wild peach pits, and the wild peach pits with different diameters fall onto the surface of the guide plate 101 through the sieve holes 106 in turn. The guide plate 101 is also correspondingly connected to the three sieve barrels 105 and plays a blocking effect through the partition plates 102, facilitating the transmission of the screened wild peach pits with different diameters to the inside of the shelling group 300 for shelling and crushing treatment.
[0043] Therefore, on the basis of the above structure, combined with Figure 3 - Figure 5As shown, the structure of the side plate 200 is further disclosed. A baffle 202 is fixedly connected to the bottom of the fixing plate 201. The baffle 202 is arc-shaped. The length of the baffle 202 matches the length of the three grading buckets 105 and is distributed on the back of the grading buckets 105. The bottom is correspondingly communicated with the upper part of the material guiding plate 101.
[0044] Furthermore, since some of the wild peach kernels match the diameter size of the grading holes 106 and are stuck at the positions of the grading holes 106, and rotate with the grading buckets 105, it is necessary to manually remove the wild peach kernels stuck in the grading holes 106. When the grading holes 106 with wild peach kernels rotate to the surface position of the baffle 202 through the rotation of the grading buckets 105, since one end of the wild peach kernel is stuck in the grading holes 106 and will protrude from the positions of the grading holes 106, it will contact the surface of the extrusion block 203. After the collision, pressure is generated, and the wild peach kernels can be detached from the positions of the grading holes 106, avoiding the need to manually remove the wild peach kernels from the surface of the grading holes 106 and effectively improving the grading work efficiency of the wild peach kernels.
[0045] Therefore, on the basis of the above structure, combined with Figure 6 - Figure 8 As shown, the structure of the shelling group 300 is further disclosed. A discharge port 301 is opened at the bottom of the front end of the shelling group 300. A cover plate 302 is fixedly installed above the shelling group 300. A second driving motor 303 is fixedly installed on the side of the shelling group 300. A connecting plate 305 is fixedly installed inside the shelling group 300.
[0046] Furthermore, the graded wild peach kernels fall from the grading holes 106 onto the surface of the material guiding plate 101. Since the material guiding plate 101 is inclined and arranged below the grading buckets 105, the wild peach kernels will roll above the material guiding plate 101. A through groove is opened at a position on one side of the cover plate 302 close to the material guiding plate 101. The inside of the shelling group 300 is correspondingly communicated with the material guiding plate 101 through the through groove, and the graded wild peach kernels are transported into the shelling group 300. The second driving motor 303 is started to drive the stirring rod 304 to rotate. There are two stirring rods 304 in total, and the two stirring rods 304 are symmetrically distributed inside the shelling group 300. The wild peach kernels falling from the through groove position are directly transported to the middle position between the two stirring rods 304. When the two stirring rods 304 rotate and stir, the outer shells of the wild peach kernels are extruded, so that the outer shells of the wild peach kernels are broken. The broken outer shells of the wild peach kernels and the kernels are discharged from the discharge port 301 position, and finally the broken outer shells of the wild peach kernels and the kernels are separated.
[0047] In summary, the working principle of this solution is as follows: Pour the wild peach kernels from the feeding bucket 104 and let them fall inside the screening bucket 105. The screening bucket 105 drives the drive shaft 108 to rotate by means of the first driving motor 107 to conduct screening treatment on the wild peach kernels. Under the action of centrifugal force, the wild peach kernels of different diameters are screened out from the bottom of the screening bucket 105 and fall onto the surface of the guide plate 101. Since there are wild peach kernels with a diameter similar to that of the screening holes 106, they will get stuck on the surface of the screening holes 106 and keep rotating with the screening bucket 105, affecting the subsequent screening efficiency of the wild peach kernels. By arranging the extrusion block 203 to contact the surface of the wild peach kernels stuck on the surface of the screening holes 106 and using the extrusion force, the wild peach kernels are extruded from the surface of the screening holes 106 to ensure the normal screening operation of the wild peach kernels;
[0048] Transfer the screened wild peach kernels to the guide plate 101, and use the through groove opened at a position close to the guide plate 101 on one side of the cover plate 302 to transfer the screened wild peach kernels into the shelling group 300, directly introducing them to the middle position between the two stirring rods 304. Crush the wild peach kernels by rotating the two stirring rods 304 and discharge them from the discharge port 301 position. Finally, separate the crushed wild peach kernels and the kernels.
[0049] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
