Description

Technical Field

[0001] The invention relates to the technical field of tea oil production, in particular to an automatic rotary crushing and screening machine for tea seeds. Background Art

[0002] Camellia seeds are the seeds of the tea tree and are mainly used to extract camellia oil. Before extracting the oil, the shells of the camellia seeds need to be peeled off, and then the shelled camellia seeds need to be crushed into particles of a specified size. The tea oil in the camellia seeds is then extracted through oil extraction techniques such as pressing or leaching.

[0003] However, there are usually some problems when crushing tea seeds. With the development of science and technology, technical personnel in related fields have also optimized the crushing methods of tea seeds. In order to make a more accurate comparison, a Chinese patent with publication number CN111229387A discloses an automatic screening and crushing cylinder of a tea seed crusher, including a filter cylinder, a rotating disk is fixedly connected to the bottom of the filter cylinder, a center plate is rotatably connected to the bottom of the rotating disk, a power rod is vertically penetrated at the bottom of the center plate, a crushing cylinder is vertically arranged inside the filter cylinder, a fixed plate is fixedly connected to the bottom of the crushing cylinder, a spiral plate is arranged around the inner side wall of the filter cylinder, a discharge port is arranged around the top of the fixed plate, a power wheel is arranged inside the fixed plate, a rotating gear is rotatably connected to one side of the power wheel, a rotating rod is arranged inside the crushing cylinder, and a fixed gear ring is arranged at the bottom of the rotating rod.

[0004] When the above-mentioned prior art is in use, the power device drives the power rod to rotate, and then the power wheel drives the rotating gear to rotate, and the rotating gear drives the rotating rod to rotate through the fixed gear ring, so that the power rod and the crushing rod on the surface of the rotating rod rotate, and the crushing rod collides with the tea seeds to crush the tea seeds, so that the crushed tea seeds leak out through the leakage hole. During this period, the uncrushed tea seeds are rotated and lifted up by the spiral plate at the bottom of the filter cylinder to the crushing cylinder for re-crushing.

[0005] However, there are still some shortcomings in the process of crushing camellia seeds in the above-mentioned prior art:

[0006] 1. Since the surface of tea seeds is usually attached with shells, the shells will be mixed in after they are crushed, and the shells of tea seeds need to be removed during the oil extraction process. However, the above-mentioned prior art cannot remove the shells in tea seeds, which directly affects the quality of the extracted tea oil, and it is easy for the shell fragments to enter the tea oil, affecting the consumer's experience when using the tea oil.

[0007] 2. Since the camellia seeds are very hard after drying and their appearance is mostly oval, the above-mentioned prior art crushes the camellia seeds by mutual collision between the crushing rods and the camellia seeds, which easily causes the camellia seeds to fall through the gaps between the crushing rods and cannot be fully crushed. Therefore, it takes repeated attempts to completely crush them into particles of a specified size, thus affecting the crushing efficiency.

[0008] 3. In addition, before crushing, in order to facilitate shelling, the tea seeds usually need to be dried, such as by natural drying and heating to evaporate the internal moisture. However, the above-mentioned prior art can only crush the dried tea seeds, and cannot dry and crush the tea seeds at the same time, and the dried tea seeds need to be poured into a crushing barrel, which increases unnecessary workload and wastes time and the processing cost of the tea seeds.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing camellia seed crushing methods. Summary of the invention

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-Figure 13 Embodiments of the present invention are described in detail.

[0048] The embodiment of the present application discloses an automatic rotary crushing and screening machine for camellia seeds. The automatic rotary crushing and screening machine for camellia seeds is mainly used in the process of crushing and screening camellia seeds. In terms of technical effect, it can continuously crush, separate and screen the camellia seeds to improve work efficiency. During the process, the camellia seeds are squeezed and crushed to prevent the smooth surface of the camellia seeds from being difficult to crush quickly. In particular, in the process of crushing the camellia seeds, the camellia seeds can be heated to allow the moisture in the camellia seeds to evaporate quickly, thereby ensuring that the camellia seeds and the shells can be quickly separated, thereby enhancing the screening effect. Furthermore, the automatic rotary crushing and screening machine for camellia seeds can also screen the crushed camellia seed kernels and shells by air selection, and the shells can be blown out during the process to completely separate the camellia seed kernels and the shells.

[0049] Embodiment 1:

[0050] Reference Figure 1 and Figure 2 As shown, an automatic rotary crushing and screening machine for camellia seeds comprises a processing cylinder 1, a support shaft 2 is rotatably mounted on the upper side of the processing cylinder 1, a crushing cylinder 3 is rotatably sleeved on the outer wall of the support shaft 2, and a feeding pipe 31 for pouring camellia seeds into the crushing cylinder 3 is arranged at either end.

[0051] Furthermore, in this embodiment, a driving unit 4 is arranged between the support shaft 2 and the outer wall of the crushing cylinder 3, and the driving unit 4 includes a driving motor 41 installed on the outer wall of the processing cylinder 1 through a motor seat and connected to the support shaft 2. An execution unit 5 for crushing tea seeds is arranged between the support shaft 2 and the outer wall of the crushing cylinder 3. A screening unit 6 for separating the crushed tea seeds and their shells is also arranged on the processing cylinder 1. The screening unit 6 includes a plurality of discharge cylinders 61 installed on the outer wall of the processing cylinder 1.

[0052] During the specific implementation process, the tea seeds are first poured into the crushing cylinder 3 through the feeding pipe 31, and then the driving unit 4 controls the support shaft 2 and the crushing cylinder 3 to rotate, and cooperates with the execution unit 5 to squeeze and crush the tea seeds. During this period, the tea seeds in the crushing cylinder 3 are heated and dried by the execution unit 5 to quickly evaporate the moisture inside, thereby facilitating the separation of the crushed tea seeds and the shells; then the crushing cylinder 3 discharges the crushed tea seeds and shells downward along the processing cylinder 1, and blows off the shells through the screening unit 6, thereby completing the screening of the tea seeds, and then the processed tea kernels are collected at the bottom of the processing cylinder 1.

[0053] Continue to refer to Figure 2As shown, since the crushing drum 3 needs to rotate during the crushing process of tea seeds, in order to facilitate the addition of tea seeds into the crushing drum 3 during the rotation process, in this embodiment, a plurality of annularly distributed fan-shaped material openings 32 are opened at one end of the crushing drum 3 close to the feed pipe 31, and an annular frame 33 is rotatably provided on the end of the crushing drum 3 and is sleeved on the outside of the plurality of fan-shaped material openings 32. The annular frame 33 will not interfere with the rotation of the crushing drum 3. One end of the feed pipe 31 passes through the annular frame 33 and is connected with the fan-shaped material opening 32, and the other end passes through the processing drum 1 and a hopper 34 is installed thereon.

[0054] During the specific implementation process, after the tea seeds are poured into the hopper 34, the tea seeds are discharged into the annular frame 33 through the feed pipe 31 and enter the crushing drum 3 through the fan-shaped material opening 32. The crushing drum 3 drives the multiple fan-shaped material openings 32 to keep rotating all the time, and the tea seeds can enter the crushing drum 3 through the multiple fan-shaped material openings 32 respectively, thereby avoiding the accumulation of tea seeds between the annular frame 33 and the crushing drum 3 to cause blockage, and then the tea seeds to be crushed can be continuously added to the crushing drum 3, which is convenient for cooperating with the execution part 5 to continuously crush the tea seeds, thereby improving work efficiency.

[0055] Reference Figure 3 As shown, in order to facilitate the crushing of tea seeds through the cooperation between the support shaft 2, the crushing barrel 3 and the execution part 5, in this embodiment, the support shaft 2 and the crushing barrel 3 are both horizontally placed on the inner wall of the processing barrel 1, and the driving part 4 also includes two linked bevel gear rings 42 installed on the outer walls of both ends of the crushing barrel 3, and the outer wall of the support shaft 2 is provided with two control bevel gear rings 43 respectively arranged opposite to the linked bevel gear rings 42.

[0056] Furthermore, in this embodiment, two positioning plates 44 are symmetrically arranged on the inner walls on both sides of the end of the processing cylinder 1 relative to the crushing cylinder 3 along the support shaft 2, and a transmission bevel gear 46 meshing with the linkage bevel gear ring 42 and the control bevel gear ring 43 is rotatably arranged on the positioning plate 44 through the positioning shaft 45.

[0057] During the specific implementation process, when the driving motor 41 drives the support shaft 2 to rotate, the support shaft 2 drives the transmission bevel gear 46 to rotate through the control bevel gear ring 43, and the transmission bevel gear 46 drives the crushing drum 3 to rotate through the linkage bevel gear ring 42, and the control bevel gear ring 43 and the linkage bevel gear ring 42 have opposite directions, so that the support shaft 2 and the crushing drum 3 rotate relative to each other, so as to cooperate with the execution part 5 to crush the tea seeds, thereby improving the crushing efficiency and crushing strength.

[0058] Reference Figure 2 and Figure 4As shown, in order to facilitate the crushing of tea seeds, in this embodiment, the execution part 5 includes a plurality of rotating frames 51 installed on the outer wall of the support shaft 2, and a plurality of linkage frames 52 are installed on the inner wall of the crushing cylinder 3. The rotating frames 51 and the linkage frames 52 both have a plurality of support rods 53 equidistantly distributed along the axial direction of the support shaft 2, and the support rods 53 on the rotating frames 51 and the linkage frames 52 are staggered, and a plurality of staggered extrusion columns 54 are rotatably arranged on the support rods 53 of the rotating frames 51 and the linkage frames 52.

[0059] Furthermore, in this embodiment, a plurality of discharge ports 55 staggered with the linkage frame 52 are evenly opened on the outer wall of the crushing cylinder 3, and a heat drying branch chain 56 for accelerating the evaporation of water inside the oil tea seeds is provided between the support shaft 2 and the rotating frame 51.

[0060] It should be noted that the outer wall of the extrusion column 54 is evenly installed with multiple annularly distributed raised strips for increasing friction. The raised strips can prevent the extrusion column 54 from making smooth contact with the tea seeds, making it difficult to perform extrusion and crushing, thereby enhancing the crushing efficiency.

[0061] During the specific implementation process, during the relative rotation of the support shaft 2 and the crushing drum 3, the support shaft 2 and the crushing drum 3 respectively drive the rotating frame 51 and the linkage frame 52 to move in a relative circumferential direction, so that the oil tea seeds are squeezed and crushed by the extrusion columns 54 on the rotating frame 51 and the linkage frame 52, and the multiple extrusion columns 54 can effectively prevent the oil tea seeds from being smooth and difficult to crush quickly; during this period, when the crushing drum 3 rotates, the oil tea seeds inside it are thrown out through the discharge port 55 under the action of centrifugal force and fall downward, so as to separate the crushed oil tea seeds and the shells through the screening part 6; at this time, the oil tea seeds in the crushing process can be heated and dried by the hot drying branch chain 56, so that the moisture inside the oil tea seeds can be quickly evaporated, so as to speed up the separation speed and separation effect of the oil tea seeds and the shells.

[0062] Reference Figure 5 and Figure 6 As shown, in order to facilitate the rapid separation of the tea seeds from the shell after being crushed, the moisture inside the tea seeds needs to be evaporated quickly. Based on this, a hot drying branch chain 56 is provided in this embodiment. Specifically, the hot drying branch chain 56 includes an air storage cavity 561 opened inside the support shaft 2, and a first air pump 562 is installed on the side of the outer wall of the processing cylinder 1 away from the driving motor 41 through a bracket. The air delivery end of the first air pump 562 is installed with an exhaust pipe extending into the air storage cavity 561, and the exhaust pipe rotates through the support shaft 2.

[0063] Furthermore, in this embodiment, a plurality of air outlets 563 corresponding to the positions of the support rods 53 are provided on the support shaft 2, an air duct 564 connected to the air outlet 563 is provided inside the support rod 53, and a plurality of exhaust holes 565 connected to the air duct 564 are provided on the outer wall of the support rod 53, a plurality of receiving plates 566 corresponding to the positions of the rotating frame 51 are installed on the inner wall of the air storage chamber 561, and a plurality of electric heating tubes 567 are provided on the receiving plates 566 and extend into the air duct 564 after passing through the air outlet 563.

[0064] In the specific implementation process, before pouring the tea seeds into the crushing cylinder 3, first start the first air pump 562 and the electric heating tube 567. The first air pump 562 inputs external air into the air storage chamber 561 and discharges it from the exhaust hole 565 after passing through the air outlet 563 and the air channel 564. At this time, the air in the air channel 564 is heated by the electric heating tube 567, so as to ensure that the high-temperature air heated in the air channel 564 can heat the inside of the crushing cylinder 3 when it is discharged.

[0065] When the tea seeds are subsequently poured into the crushing drum 3, the tea seeds can be heated by the heat inside the drum and crushed while being heated, so that the moisture in the tea seeds can be quickly evaporated, and the tea seeds and the shells can be quickly separated during the crushing process, avoiding the tea seeds and the shells from sticking together and being difficult to separate, thereby enhancing the screening effect; and the water vapor in the crushing drum 3 will be discharged to the outside through the discharge port 55.

[0066] Reference Figure 7 and Figure 8 As shown, in order to prevent the discharge port 55 from being blocked by the camellia seeds with a larger diameter, it is necessary to dredge the camellia seeds when they are thrown out of the crushing drum 3. Based on this, in this embodiment, an anti-clogging branch chain 57 for dredging the discharge port 55 is installed on the inner wall of the processing drum 1. Specifically, the anti-clogging branch chain 57 includes an arc plate 571 installed on the inner wall of the processing drum 1 and located above the crushing drum 3. A plurality of dredging groups are arranged along the circumferential direction at the lower end of the arc plate 571, and each dredging group includes a plurality of top blocks 572 corresponding to the position of the discharge port 55.

[0067] Furthermore, in this embodiment, the discharge port 55 is composed of a discharge hole and two tapered holes, the two tapered holes are interconnected through the discharge hole, and the diameter of the tapered hole gradually decreases toward the side close to the discharge hole, an elastic member 573 is installed between the top block 572 and the arc plate 571, and the top block 572 is a conical structure that conflicts with the side of the discharge port 55 away from the axis of the crushing barrel 3.

[0068] It should be noted that the elastic member 573 always applies an elastic force having a tendency to move toward the side of the crushing cylinder 3 to the top block 572 , so that the top block 572 always abuts against the outer wall of the crushing cylinder 3 .

[0069] During the specific implementation process, when the discharge port 55 on the outer wall of the crushing drum 3 coincides with the top block 572, the top block 572 is quickly inserted into the discharge port 55 under the action of the elastic member 573, so that the oil tea seeds blocked in the discharge port 55 can be pushed out to the inside of the crushing drum 3 for further crushing. This can prevent the discharge port 55 from being blocked, which makes it difficult for the qualified oil tea seeds to be thrown out, thereby ensuring that the oil tea seeds can be thrown out from the discharge port 55 only after being crushed to a specified diameter, so that the oil tea seeds can be fully crushed, and there is no need to pour the oil tea seeds with larger diameter back into the crushing drum 3 for repeated crushing, thereby reducing unnecessary workload.

[0070] In addition, when the crushing drum 3 throws out the tea seeds, the arc plate 571 can cover the top of the crushing drum 3 to prevent the tea seeds from being thrown out from the top of the crushing drum 3 and causing waste, and the top of the processing drum 1 is not closed to facilitate the discharge of steam in the crushing drum 3.

[0071] Reference Fig. 9 and Fig.10 As shown, in order to completely separate the crushed tea seeds and the shells, they need to be screened so as to collect the tea seeds. Based on this, a screening part 6 is also provided in this embodiment. Specifically, the screening part 6 also includes an air tank 62 installed inside the processing cylinder 1 through a plurality of fixing rods. The air tank 62 is located below the crushing cylinder 3. A plurality of second air pumps 63 are installed on the upper end of the air tank 62. The air inlet end of the second air pump 63 extends to the outside after passing through the processing cylinder 1, and the air delivery end of the second air pump 63 extends to the inside of the air tank 62. A plurality of nozzles are evenly installed on the outer wall of the air tank 62. A plurality of through holes 64 are opened on the outer wall of the processing cylinder 1 at the same height as the air tank 62. A discharge cylinder 61 for discharging the shells of the tea seeds is installed on the outer wall of the through hole 64.

[0072] Furthermore, in this embodiment, the discharge cylinder 61 is composed of an ascending cylinder 611, a transition cylinder 612 and a descending cylinder 613, wherein the ascending cylinder 611 connected to the processing cylinder 1 gradually tilts upward toward the side away from the processing cylinder 1, and the side of the ascending cylinder 611 away from the processing cylinder 1 is equipped with a downward tilted descending cylinder 613 through the transition cylinder 612.

[0073] It should be noted that a plurality of step bars 614 are installed on the inner bottom wall of the lifting cylinder 611 . The side of the step bars 614 away from the processing cylinder 1 gradually tilts upward, and there is a sinking groove between two adjacent step bars 614 .

[0074] During the specific implementation process, the crushed tea kernels and shells are thrown out from the crushing cylinder 3 and fall downward. At this time, the second air pump 63 is started, and the second air pump 63 inputs air into the air storage tank 62 and sprays it to the side of the through hole 64 through the nozzle; when the tea kernels and shells fall to the side of the through hole 64, the airflow ejected by the nozzle can blow the shells into the through hole 64 and be discharged through the discharge cylinder 61, while the tea kernels fall downward along the processing cylinder 1 for collection, so that the tea kernels and shells are screened by air selection.

[0075] It should be further explained that, since the moisture in the tea seeds evaporates due to heat during the crushing process, the weight of the tea seed kernel is greater than the weight of its shell. Therefore, the tea seed kernel will not be blown into the discharge barrel 61 by air selection. On the contrary, only the lighter shell can be blown into the discharge barrel 61.

[0076] During the screening process, since the camellia kernels with smaller diameters are also lighter in weight, they are easily blown out into the discharge barrel 61. At this time, the camellia kernels and shells can be blocked by the lifting barrel 611 and the step bars 614, so that the camellia kernels and shells fall into the sinking trough. At this time, the nozzle continues to spray air toward the through hole 64, which can blow up the camellia seed shells in the sinking trough and discharge them after passing through the transition barrel 612 and the discharge barrel 613, while the camellia kernels accumulate in the sinking trough and cannot be blown up, so that the camellia kernels and shells can be further screened, so as to completely separate the camellia kernels and shells, and then the camellia kernels in the sinking trough can be poured out and collected.

[0077] Embodiment 2:

[0078] Reference Fig.11 , Fig.12 and Fig.13 As shown, on the basis of Example 1, in order to ensure that the crushed tea seed kernels and shells can be completely separated, a kneading part 7 for peeling the tea seed shells off the tea seed kernels is also provided in this embodiment. Specifically, the kneading part 7 includes a fixed plate 71 installed on the inner wall of the processing cylinder 1 through a positioning block, the fixed plate 71 is located below the crushing cylinder 3 and above the air storage tank 62, and a through hole for receiving the tea seeds and shells is opened at the upper end of the fixed plate 71, and a collecting hopper 72 located below the crushing cylinder 3 is also installed on the inner wall of the processing cylinder 1, and the lower end of the collecting hopper 72 gradually shrinks and is connected to the through hole.

[0079] Furthermore, in this embodiment, a positioning vortex rod 73 is installed at the lower end of the fixed disk 71, a rotating disk 74 is rotatably arranged below the fixed disk 71, and a linkage vortex rod 75 that cooperates with the positioning vortex rod 73 is installed at the upper end of the rotating disk 74. A plurality of annularly distributed drop holes 76 are evenly opened on the rotating disk 74 near its edge, and the middle part of the rotating disk 74 has an upwardly protruding frustum, through which the tea seeds and shells falling from the through hole can be guided between the positioning vortex rod 73 and the linkage vortex rod 75.

[0080] Furthermore, in this embodiment, an annular support frame 77 rotatably arranged at the lower end of the rotating disk 74 is installed on the inner wall of the processing cylinder 1, a bevel gear ring 78 is sleeved on the outer wall of the rotating disk 74, a connecting shaft 79 is passed through the side wall of the processing cylinder 1 close to the driving motor 41, an auxiliary bevel gear 80 meshing with the bevel gear ring 78 is sleeved on the outer wall of the connecting shaft 79, and the connecting shaft 79 is connected to the output shaft of the driving motor 41 through a belt drive.

[0081] During the specific implementation process, the crushed tea seeds and shells are thrown out by the crushing cylinder 3 and then fall between the fixed disk 71 and the rotating disk 74 after passing through the collecting hopper 72 and the through hole. During this period, the output shaft of the driving motor 41 drives the bevel gear and the rotating disk 74 to rotate through the connecting shaft 79 and the auxiliary bevel gear 80, so that the rotating disk 74 drives the linked vortex rod 75 and the fixed disk 71 and the positioning vortex rod 73 to rotate relative to each other, so that the linked vortex rod 75 and the positioning vortex rod 73 can gradually transport the tea seeds and shells to their outer edge. At the same time, they can be kneaded to facilitate the complete separation of the tea kernels and shells that fit each other, thereby enhancing the screening effect, thereby improving the overall quality of the tea kernels after screening, and then the kneaded tea kernels and shells are transported to the outer edge of the rotating disk 74 and fall downward through the drop hole 76.

[0082] During operation: Step 1: First, start the first air pump 562 and the electric heating tube 567. The first air pump 562 inputs air into the air storage chamber 561 and discharges it from the exhaust hole 565 after passing through the air outlet 563 and the air duct 564. At this time, the air in the air duct 564 is heated by the electric heating tube 567, so that the heated high-temperature air can heat the inside of the crushing barrel 3 when it is discharged; secondly, start the drive motor 41, and the drive motor 41 drives the support shaft 2 to rotate. During this period, the crushing barrel 3 can be driven to rotate by controlling the coordination between the bevel gear ring 43, the transmission bevel gear 46 and the linkage bevel gear ring 42, and the support shaft 2 and the crushing barrel 3 rotate relative to each other.

[0083] The second step: pour the tea seeds into the crushing drum 3 through the feed pipe 31. At this time, the support shaft 2 and the crushing drum 3 respectively drive the rotating frame 51 and the linkage frame 52 to move in relative circumferential directions and extrude and crush the tea seeds through the extrusion column 54. During this period, the heat inside the crushing drum 3 can heat the tea seeds to quickly evaporate the moisture in the tea seeds, so that the tea seeds and the shell can be quickly separated during the crushing process, and the water vapor in the crushing drum 3 will be discharged to the outside through the discharge port 55.

[0084] Step 3: When the crushing drum 3 rotates, the tea seeds inside it are thrown out through the discharge port 55 under the action of centrifugal force and fall downward. When the discharge port 55 on the outer wall of the crushing drum 3 coincides with the top block 572, the top block 572 can push the tea seeds blocked in the discharge port 55 into the crushing drum 3 for further crushing. This can prevent the discharge port 55 from being blocked and affecting the difficulty in throwing out the tea seeds that meet the conditions, thereby ensuring that the tea seeds can be thrown out from the discharge port 55 only after being crushed to a specified diameter, so that the tea seeds can be fully crushed.

[0085] Step 4: The crushed tea seeds and shells are thrown out by the crushing cylinder 3, and then fall between the fixed disk 71 and the rotating disk 74 after passing through the collecting hopper 72 and the through hole. During this period, the output shaft of the driving motor 41 drives the bevel gear and the rotating disk 74 to rotate through the connecting shaft 79 and the auxiliary bevel gear 80, so that the rotating disk 74 drives the linked vortex rod 75 and the fixed disk 71 and the positioning vortex rod 73 to rotate relative to each other.

[0086] The linked vortex rod 75 and the positioning vortex rod 73 can gradually transport the tea seeds and shells to their outer edge and rub them, so that the tea seed kernels and shells that are attached to each other can be completely separated, thereby enhancing the screening effect and improving the overall quality of the tea seed kernels after screening. Subsequently, the kneaded tea seed kernels and shells are transported to the outer edge of the rotating disk 74 and fall downward through the drop hole 76.

[0087] Step 5: The crushed camellia kernels and shells are thrown out from the crushing cylinder 3 and fall downward. At this time, the second air pump 63 is started. The second air pump 63 inputs air into the air storage tank 62 and sprays it to one side of the through hole 64 through the nozzle, and blows the camellia seed shells into the through hole 64 and is discharged through the discharge cylinder 61. The camellia kernels fall downward along the processing cylinder 1 for collection, so that the camellia kernels and shells are screened by air selection.

[0088] During the screening process, the lifting cylinder 611 and the step bars 614 can block the lighter camellia kernels and shells, causing them to fall into the sinking trough. At this time, the nozzle can blow up the camellia shells in the sinking trough and discharge them after passing through the transition cylinder 612 and the discharge cylinder 613, while the camellia kernels accumulate in the sinking trough and cannot be blown up, so that the camellia kernels and shells can be further screened, so as to completely separate the camellia kernels and shells, and then the camellia kernels in the sinking trough can be poured out and collected.

[0089] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

[0090] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
