[0028] Reference Figure 1 , Figure 3 and Figure 4In order to screen out tea seeds of suitable size, a servo motor 41, a screening cylinder 42, a first fixed frame 43 and a material blocking door 44 constitute a screening mechanism 4, wherein the servo motor 41 is installed on the front side of the upper part of the support box 1, the screening cylinder 42 is rotatably connected to the upper part of the support box 1, the front part of the screening cylinder 42 is bolted to the output shaft of the servo motor 41, the screening cylinder 42 is evenly provided with sieve holes, the first fixed frame 43 is installed at the front part of the screening cylinder 42, the material blocking door 44 is slidably connected to the first fixed frame 43, the part where the material blocking door 44 contacts the first fixed frame 43 is made of damping material, a feed port is provided at the upper front part of the screening cylinder 42, and the material blocking door 44 blocks the feed port on the screening cylinder 42.

[0029] Reference Figure 1 , Figure 4 and Figure 5 In order to prevent the tea seeds from clogging the sieve holes on the screening cylinder 42, the second fixed frame 51, the rotating frame 52, the anti-jamming frame 53 and the first spring 54 constitute an anti-jamming mechanism 5, wherein the second fixed frame 51 is installed on the top of the annular frame 2, the anti-jamming frame 53 is slidably connected to the second fixed frame 51, four first springs 54 are wound around the lower part of the anti-jamming frame 53, the upper and lower ends of the first spring 54 are respectively fixed to the anti-jamming frame 53 and the second fixed frame 51, the anti-jamming frame 53 moves downward and is inserted into the sieve holes on the screening cylinder 42, and the rotating frame 52 is welded on the front and rear sides of the screening cylinder 42, and the rotating frame 52 has a plurality of protrusions, and the protrusions on the rotating frame 52 rotate to contact the anti-jamming frame 53.

[0030] When it is necessary to screen the camellia seed raw materials during the camellia oil production process, the raw material screening device for camellia oil production can be used. People first open the material blocking door 44, put a proper amount of camellia seed raw materials into the screening cylinder 42, close the material blocking door 44, start the servo motor 41, and the output shaft of the servo motor 41 rotates to drive the screening cylinder 42 to rotate at a low speed. The screening cylinder 42 rotates to screen the camellia seeds. The camellia seeds of suitable sizes fall out of the sieve holes on the screening cylinder 42 into the support box 1, and the camellia seeds of unsuitable sizes remain in the screening cylinder 42, thereby screening the camellia seeds. Since the screening cylinder 42 rotates at a low speed, the camellia seeds will not splash at will. The rotation of the screening cylinder 42 drives the rotating frame 52 to rotate. When the protrusion on the rotating frame 52 rotates to contact the anti-jamming frame 53, The protrusion on the rotating frame 52 squeezes the anti-jamming frame 53 to move downward, the first spring 54 is compressed, and the anti-jamming frame 53 is inserted downward into the sieve holes on the screening cylinder 42, so that the tea seeds stuck in the sieve holes of the screening cylinder 42 can be pushed out to avoid the screening cylinder 42 from being blocked. The anti-blocking effect is good, which is conducive to the smooth progress of the tea seed screening operation. When the protrusion on the rotating frame 52 rotates to disengage from the anti-jamming frame 53, the first spring 54 is reset to make the anti-jamming frame 53 move upward and reset. When the screening of the tea seed raw material is completed, the servo motor 41 is turned off, and the rotating door 3 is opened by the handle on the rotating door 3, the tea seed raw material of suitable size in the supporting box 1 is taken out, the rotating door 3 is closed, and the material blocking door 44 is opened to process the tea seed raw material of unsuitable size in the screening cylinder 42, and the material blocking door 44 is closed.

[0031] Example 2, based on Example 1, refer to Figure 1 and Figure 6 , also includes an auxiliary mechanism 6. In order to scatter tea seeds of different sizes, the first rotating shaft 61, the auxiliary plate 62 and the torsion spring 63 constitute the auxiliary mechanism 6, wherein the first rotating shaft 61 is installed on both sides of the left and right sides of the screening cylinder 42 through bearings, and four auxiliary plates 62 are evenly welded on the first rotating shaft 61, and the auxiliary plates 62 are inclined toward the lower right. The front and rear parts of the first rotating shaft 61 are both wound with torsion springs 63, and the inner and outer ends of the torsion spring 63 are respectively fixed to the first rotating shaft 61 and the screening cylinder 42.

[0032] During the process of the screening cylinder 42 rotating to screen the tea seed raw materials, the tea seeds in the screening cylinder 42 move to hit the auxiliary plate 62, and the auxiliary plate 62 swings, so that the first rotating shaft 61 rotates forward and reverse, and the torsion spring 63 deforms adaptively. The auxiliary plate 62 scatters the tea seeds of different sizes to prevent the tea seeds of suitable sizes from being blocked by large-particle tea seeds and difficult to be screened out, which is conducive to accurately screening out the tea seeds of suitable sizes and improving the screening accuracy.

[0033] Reference Figure 1 , Figure 7 and Figure 8, also includes a dispersion mechanism 7. In order to prevent the oil-tea seeds from accumulating in the middle of the support box 1, the third fixed frame 71, the bevel gear 72, the first magnet rod 73, the limit rod 74, the second rotating shaft 75, the third rotating shaft 76, the dispersion plate 77 and the second magnet rod 78 constitute the dispersion mechanism 7, wherein the third fixed frame 71 is installed on the upper side of the rear of the support box 1, the rear of the screening drum 42 rotates through the front of the third fixed frame 71, the rear of the screening drum 42 is welded with a bevel gear 72, the upper and lower sides of the third fixed frame 71 are installed with the second rotating shaft 75 through bearings, the rear of the third fixed frame 71 is installed with the third rotating shaft 76 through bearings, the second rotating shaft 75 is welded with a bevel gear 72, and the third rotating shaft 76 is also welded with a bevel gear 72. Bevel gears 72 are welded, and adjacent bevel gears 72 mesh with each other. A dispersion plate 77 is installed on the upper inner part of the support box 1 through a bearing, and the rear part of the dispersion plate 77 passes through the rear part of the support box 1. A first magnet rod 73 is installed on the rear side of the third rotating shaft 76, and a first magnet rod 73 is also installed on the rear side of the lower part of the screening cylinder 42. Second magnet rods 78 are symmetrically installed on the front and rear sides of the upper rear side of the dispersion plate 77. The front first magnet rod 73 and the front second magnet rod 78 are magnetically matched, and the rear first magnet rod 73 and the rear second magnet rod 78 are magnetically matched. Limit rods 74 are welded on both sides of the upper and rear sides of the support box 1, and the second magnet rods 78 are located between the two limit rods 74. The second magnet rods 78 rotate and contact with the limit rods 74.

[0034] In the process of screening the tea seeds, the tea seeds of suitable size fall on the dispersion plate 77, the screening drum 42 rotates to drive the first magnet rod 73 at the front to rotate, and the screening drum 42 rotates to drive the bevel gear 72 at the front to rotate, so that the bevel gears 72 on the left and right sides rotate, and then the bevel gear 72 at the rear rotates, and the bevel gear 72 at the rear side rotates through the third shaft 76 to rotate the first magnet rod 73 at the rear, and the first magnet rods 73 on the front and rear sides rotate in opposite directions. When the first magnet rod 73 at the front rotates to contact the second magnet rod 78 at the front, the first magnet rod 73 at the front and the second magnet rod 78 at the front are magnetically attracted, so that the dispersion plate 77 rotates to the left, and the second magnet rod 78 at the front rotates to contact the left limit rod 74. When in contact, the front second magnet rod 78 is intercepted, the front first magnet rod 73 and the front second magnet rod 78 are separated, and then the rear first magnet rod 73 rotates to contact the rear second magnet rod 78, and the rear first magnet rod 73 and the rear second magnet rod 78 are magnetically attracted, so that the dispersion plate 77 rotates to the right, and when the rear second magnet rod 78 rotates to contact the right limit rod 74, the rear second magnet rod 78 is intercepted, and the rear first magnet rod 73 and the rear second magnet rod 78 are separated. By rotating the dispersion plate 77 left and right, the tea seeds of suitable sizes can be transported to the left and right sides of the support box 1, thereby avoiding the accumulation of tea seeds in the middle of the support box 1, and making full use of the internal space of the support box 1.

[0035] Reference Figure 1 and Fig. 9 , also includes an entry and exit mechanism 8. In order to enhance the stability of the material blocking door 44 and prevent the material blocking door 44 from opening accidentally, a discharging plate 81, a second spring 82, a latch 83 and a third spring 84 constitute the entry and exit mechanism 8, wherein the latch 83 is slidably connected to the right part of the first fixed frame 43, the latch 83 is stuck at the bottom of the material blocking door 44, the third spring 84 is connected between the pin 83 and the first fixed frame 43, the left and right sides of the bottom of the material blocking door 44 are fixedly connected with the second spring 82, the lower part of the second spring 82 is fixedly connected to the first fixed frame 43, the discharging plate 81 is connected to the front upper part of the support box 1, a discharging port is opened at the front upper part of the support box 1, and the discharging plate 81 is located at the discharging port on the support box 1.

[0036] Initially, the material blocking door 44 is in a closed state, the second spring 82 is stretched, and the latch 83 is stuck at the bottom of the material blocking door 44. When the material blocking door 44 needs to be opened, the latch 83 is pulled to the right, the third spring 84 is stretched, the latch 83 moves to the right and no longer blocks the material blocking door 44, and the second spring 82 is reset to make the material blocking door 44 move downward and open. In this way, the material blocking door 44 can be automatically opened, which is beneficial to improving the efficiency of screening camellia seed raw materials. After the material blocking door 44 moves downward, the latch 83 is released, and the elastic force of the third spring 84 makes the latch 83 abut against the right side of the material blocking door 44. Then the camellia seed raw materials can be loaded into the screening cylinder 42. When the camellia seed raw materials are screened, When the blocking door 44 is completed and the unsuitable camellia seeds in the screening cylinder 42 need to be processed, when the discharge port on the screening cylinder 42 corresponds to the discharge port on the supporting box 1, the blocking door 44 is opened, and the unsuitable camellia seeds can slide out through the discharge plate 81. When the blocking door 44 needs to be closed, the blocking door 44 is manually pulled to reset, and the second spring 82 is stretched. When the blocking door 44 moves upward to disengage from the latch 83, the third spring 84 is reset to make the latch 83 move to the left to jam the bottom of the blocking door 44. This can enhance the stability of the blocking door 44, avoid accidental opening of the blocking door 44, and facilitate safe and stable camellia seed screening operations.

[0037] Reference Figure 1 and Fig.10 , also includes a buffer mechanism 9. In order to provide buffer protection for the tea seed raw materials falling into the support box 1, a buffer plate 91, a fourth spring 92 and a magnet plate 93 constitute the buffer mechanism 9, wherein the buffer plate 91 is slidably connected to the inside of the support box 1, and the fourth springs 92 are fixedly connected to the left and right sides of the bottom of the buffer plate 91, and the lower parts of the fourth springs 92 are fixedly connected to the bottom of the support box 1. There are two magnet plates 93, one magnet plate 93 is installed in the middle of the bottom of the buffer plate 91, and the other magnet plate 93 is installed in the middle of the bottom of the support box 1, and the upper and lower magnet plates 93 are magnetically matched.

[0038] In the process of screening the camellia seed raw materials, the camellia seeds of suitable size fall on the buffer plate 91, and the elastic force of the fourth spring 92 buffers the camellia seeds through the buffer plate 91, thereby preventing the camellia seeds from falling directly on the bottom of the support box 1 and being damaged, which is conducive to keeping the camellia seeds intact. As the number of camellia seeds on the buffer plate 91 increases, the buffer plate 91 moves downward, the fourth spring 92 is compressed, and the buffer plate 91 drives the upper magnet plate 93 to move downward. When the upper magnet plate 93 moves downward to contact with the lower magnet plate 93, the two magnet plates 93 are magnetically attracted, and when the rotating door 3 is opened, the upper magnet plate 93 moves downward to contact with the lower magnet plate 93. After that, the oil tea seeds on the buffer plate 91 gradually slide out, and the two magnet plates 93 are magnetically attracted to fix the buffer plate 91, thereby preventing the buffer plate 91 from moving upward due to the elastic force of the fourth spring 92 before the oil tea seeds on the buffer plate 91 are completely removed, so that it is convenient to remove all the oil tea seeds on the buffer plate 91. After all the materials on the buffer plate 91 are removed, the buffer plate 91 is manually pulled upward to separate the two magnet plates 93, and then the buffer plate 91 is released, and the fourth spring 92 is reset to make the buffer plate 91 move upward and reset, and then the rotating door 3 is rotated to close.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
