Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oil-tea camellia fruit seed shell separation equipment, and in particular relates to an oil-tea camellia fruit seed shell sorting roller and a sorting system. Background Art
[0002] After the oil tea fruit is harvested, it is usually necessary to peel and remove the seeds. The fresh oil tea fruit is exposed to the sun for a few days, and the fruit will crack by itself. Most of the seeds will fall out by themselves, and then the slag shells are separated to obtain the oil tea seeds. The existing oil tea fruit seed shell separation equipment mostly uses a mesh drum or a mesh drum, which can only separate materials of different sizes by the size of the holes. However, the size of the oil tea seed is between 7 and 27 mm, and the size of the oil tea shell is irregular (when the thickness of the oil tea shell is less than 7 mm, its length may be greater than 7 mm). At this time, the mesh drum or mesh drum with a separation aperture of 7 mm cannot sort out the oil tea shells of this size, which increases the processing difficulty of the sorting equipment.
[0003] In addition, there is a large overlap in the sizes of tea seeds and shells. For example, the size of tea seeds is between 7 and 27 mm, while the size of tea shells is between 5 and 50 mm. The screen drum or sieve drum can only separate the tea shells other than the size of tea seeds through multi-stage separation, while the shells of 7 to 27 mm in size cannot be separated at all. Therefore, a device suitable for sorting tea seed shells is needed. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0028] like Figure 1As shown, the present application discloses a tea seed shell sorting drum, including a rotatable round rod sorting part 31 and a perforated plate sorting part 32, wherein the round rod sorting part 31 is coaxially arranged with the perforated plate sorting part 32, and the round rod sorting part 31 includes a plurality of round rods 33 arranged in parallel and spaced apart in pairs, and the plurality of round rods 33 are combined to form a drum screen; the outlet of the round rod sorting part 31 is fixedly connected with the inlet of the perforated plate sorting part 32, and the sorting size L of the round rod sorting part 31 is smaller than the sorting size φ of the perforated plate sorting part 32. A seed shell feeding section 34 is provided at the inlet of the round rod sorting part 31. The sorting size L corresponds to the minimum size of tea seeds, and the sorting size φ corresponds to the maximum size of tea seeds. For example, the size of tea seeds is between 7 and 27 mm, so the sorting size L is 7 mm, and the sorting size φ can be 33 mm. The sorting size L refers to the shortest distance between adjacent round rods 33. The selection dimension φ refers to the diameter of the selection holes of the orifice plate selection part 32 .
[0029] Furthermore, the round rod sorting part 31 rotates synchronously with the orifice plate sorting part 32. Specifically, the round rod sorting part 31 and the orifice plate sorting part 32 are driven by a power mechanism to rotate on the same third rotating shaft 35, and the outer periphery of the third rotating shaft 35 is connected to the inlet end of the round rod sorting part 31 and the outlet end of the orifice plate sorting part 32 through a connecting rod or a connecting frame, so that the third rotating shaft 35 drives the round rod sorting part 31 and the orifice plate sorting part 32 to rotate synchronously.
[0030] The specific implementation of the round rod sorting part 31 can be: comprising two annular ring seats, and the two ends of a plurality of round rods 33 are respectively fixed on the two annular ring seats, thereby forming a drum screen. One of the annular ring seats is fixedly connected to the end of the orifice plate sorting part 32 by welding or screw fixing, thereby forming a tea seed shell sorting drum.
[0031] Furthermore, the distance between two adjacent round rods 33 is a sorting size L, and L is 7 mm.
[0032] Furthermore, the sorting size φ of the orifice plate sorting part 32 is 33 mm.
[0033] The working principle of the tea seed shell sorting drum: the power mechanism drives the sorting drum to rotate, the round rod sorting section 31 and the orifice plate sorting section 32 start to rotate, and the seed shell mixture enters the round rod sorting section 31 through the seed shell feeding section 34.

[0034] like Figure 1-Figure 8The tea fruit seed shell sorting system shown in the figure comprises a hot air dryer, a drum sorting machine 3, a dough belt sorting machine and a terry belt sorting machine arranged in the order of sorting process, the hot air dryer dries fresh tea fruit; the drum sorting machine 3 sorts out a seed shell mixture with a particle size less than 33 mm; the dough belt sorting machine preliminarily separates 70% to 85% of the fruit shells, and the terry belt sorting machine separates 15% to 30% of the fruit shells, and finally tea seeds with a shell content of less than 1% are obtained.
[0035] Furthermore, the seed husk mixture with a diameter greater than 33 mm at the outlet of the perforated plate sorting part 32 enters the shelling machine and the seed husk separator 14 in sequence, and then enters the drum sorting machine 3 again. A discharging machine 1 and a feeding elevator 2 are arranged between the hot air dryer and the drum sorting machine 3; a conveying elevator 4 is arranged between the drum sorting machine 3 and the vibrating auxiliary material machine 5.
[0036] After picking, the fresh tea fruit is dried in a hot air dryer to make the tea fruit burst. The burst tea seed shell mixture enters the drum sorter 3, and the drum sorter 3 sorts out two streams of materials: a seed shell mixture larger than 33 mm and a seed shell mixture smaller than 33 mm. The seed shell mixture larger than 33 mm enters the shell breaking machine and then enters the drum sorter 3 for sorting again. The seed shell mixture smaller than 33 mm enters the dough belt sorter to preliminarily sort out most of the tea fruit shells. The tea seed shells from the dough belt sorter enter the terry belt sorter to further sort out the tea fruit shells, and finally tea seeds with a shell content of less than 1% are obtained.
[0037] Further, the specific structure of the drum sorting machine 3 is as follows: Figure 1 As shown, the drum sorting machine 3 includes a sorting drum driven to rotate by a power mechanism, and the sorting drum includes a coaxially arranged round rod sorting part 31 and a perforated plate sorting part 32, and the round rod sorting part 31 and the perforated plate sorting part 32 are coaxially arranged. Preferably, the round rod sorting part 31 and the perforated plate sorting part 32 rotate synchronously, and the round rod sorting part 31 includes a plurality of round rods 33 arranged in parallel with each other, and the plurality of round rods 33 are combined to form a drum screen; the round rod sorting part The sorting size L of 31 is smaller than the sorting size φ of the orifice plate sorting part 32; the inlet of the round rod sorting part 31 is provided with a seed shell feeding section 34; the outlet of the round rod sorting part 31 is fixedly connected to the inlet of the orifice plate sorting part 32, and the seed shell mixture after the shell bursting in the hot air dryer enters the round rod sorting part 31 and the orifice plate sorting part 32 in turn, and the seed shell mixture smaller than φ at the outlet of the orifice plate sorting part 32 enters the vibrating auxiliary material machine 5, the dough making belt sorting machine, and the terry belt sorting machine in turn. The specific implementation of the synchronous rotation of the round rod sorting part 31 and the orifice plate sorting part 32 can be as described above, of course, it can also be other implementations.
[0038] The working principle of the tea seed shell sorting drum: the power mechanism drives the sorting drum to rotate, the round rod sorting section 31 and the orifice plate sorting section 32 start to rotate, and the seed shell mixture enters the round rod sorting section 31 through the seed shell feeding section 34. After separation in the round rod sorting section 31, the broken residues and fruit shells with a size smaller than L are discharged through the gap between two adjacent round rods 33, and the seed shell mixture with a size larger than L enters the orifice plate sorting section 32; after separation in the orifice plate sorting section 32, the seed shell mixture with a size larger than φ is discharged from the orifice plate sorting section 32, and the seed shell mixture with a size smaller than φ is discharged through the sieve holes of the orifice plate sorting section 32.
[0039] Furthermore, the sorting size L of the round rod sorting part 31 is 7 mm. The sorting size φ of the orifice plate sorting part 32 is 33 mm.
[0040] Furthermore, the round rod sorting part 31 rotates synchronously with the orifice plate sorting part 32. Specifically, the round rod sorting part 31 and the orifice plate sorting part 32 are driven by a power mechanism to rotate on the same third rotating shaft 35, and the outer periphery of the third rotating shaft 35 is connected to the inlet end of the round rod sorting part 31 and the outlet end of the orifice plate sorting part 32 through a connecting rod or a connecting frame, so that the third rotating shaft 35 drives the round rod sorting part 31 and the orifice plate sorting part 32 to rotate synchronously.
[0041] Furthermore, a dust collector 16 is provided beside the drum sorting machine 3. The specific function of the dust collector 16 is to remove the dust generated during the round rod separation and the perforated plate separation process, reduce the dust pollution at the work site, and has the functions of fire prevention and explosion prevention.
[0042] Furthermore, the dough belt sorting machine includes a primary dough belt sorting machine 6 and a secondary dough belt sorting machine 7 which are arranged in sequence, and the secondary dough belt sorting machine 7 is arranged in parallel with the primary dough belt sorting machine 6 in the vertical direction. The specific structure of the dough belt sorting machine is as follows: the dough belt sorting machine includes a dough belt 61 arranged on a first active roller 63 and a first driven roller 64, the working surface of the dough belt 61 is inclined and a first feed hopper 62 is arranged above it, and a first baffle 65 is arranged on both sides of the dough belt 61 on the upper side and along the moving direction of the working surface of the dough belt 61 to prevent the oil tea fruit seed shell mixture from sliding off the two sides of the dough belt 61; when working, the dough belt 61 rotates, the oil tea fruit shell is discharged from the upper end of the dough belt 61, and the oil tea fruit seed shell mixture is discharged from the lower end of the dough belt 61 to enter the next level of sorting.
[0043] During operation, the dough-making belt 61 is arranged on the first active roller 63 and the first driven roller 64. The motor drives the first active roller 63 to rotate, and the first driven roller 64 is driven to rotate under the action of the dough-making belt 61. The oil tea fruit shell mixture enters the first feeding hopper 62 and falls onto the dough-making belt 61. The oil tea fruit shell is light in weight and has great friction with the dough-making belt 61. Therefore, the oil tea fruit shell falls onto the dough-making belt 61 and rotates with the dough-making belt 61 and is discharged from the upper end of the dough-making belt sorting machine. The oil tea fruit is heavier than the oil tea fruit shell and has less friction with the dough-making belt. Since the dough-making belt 61 is inclined, the oil tea fruit rolls downward along the inclined direction of the dough-making belt 61 and is discharged from the lower end of the dough-making belt sorting machine.
[0044] Furthermore, the loop belt sorting machine includes a primary loop belt sorting machine 8 and a secondary loop belt sorting machine 9 which are arranged in sequence. The specific structure of the loop belt sorting machine is as follows: the loop belt sorting machine includes a loop belt 82 arranged on a second active roller 84 and a second driven roller 85, the working surface of the loop belt 82 is arranged horizontally and a second feed hopper 81 is arranged above it, and a second baffle 83 is arranged on both sides of the loop belt 82 located on the upper side and along the movement direction of the working surface of the loop belt 82 to prevent the oil tea fruit seed shell mixture from sliding off the two sides of the loop belt 82; a rotatable shaking material mechanism is arranged on the side of the loop belt 82 away from its working surface and located on the inner side of the loop belt 82. When working, the shaking material mechanism rotates, and the end of the shaking material mechanism knocks the inner side of the loop belt 82, so that the oil tea fruit shell on the loop belt 82 vibrates and falls off.
[0045] Furthermore, the shaking mechanism includes a first rotating shaft 88, and at least one shaking rod 86 is arranged outside the first rotating shaft 88. The rotation of the first rotating shaft 88 drives the shaking rod 86 to rotate together. During the rotation of the shaking rod 86, the shaking rod 86 rotates to contact and hit the inner side of the loop belt 82, so that the oil tea fruit shell located on the outer side of the loop belt 82 vibrates and falls off.
[0046] Specifically, Figure 8 As shown, the first rotating shaft 88 is connected to the bearing seat 89 through a bearing, and the bearing seat 89 is fixedly arranged on the inner side of the terry belt 82; a connecting rod is fixedly arranged on the periphery of the first rotating shaft 88, and a bearing is fixedly installed on the end of the connecting rod away from the first rotating shaft 88, and one end of the shaking rod 86 is connected to the bearing. The shaking rod 86 is driven to rotate during the rotation of the first rotating shaft 88, so that the oil tea shell on the outer side of the terry belt 82 is vibrated and falls off. Preferably, the axial direction of the shaking rod 86 is parallel to the width direction of the terry belt 82; the two shaking rods 86 are symmetrically arranged on both sides of the first rotating shaft 88 in the radial direction.
[0047] Furthermore, in order to further remove the tea fruit shells adhering to the loop belt 82, a rotatable scraper mechanism is provided at one end of the loop belt 82, which is away from the tea fruit seed discharge end of the loop belt sorter. The scraper mechanism is in clearance fit with the outer side of the loop belt 82 to remove the tea fruit shells on the loop belt 82. The scraper mechanism includes a second rotating shaft and a scraper plate 87. A plurality of scraper plates 87 are provided in a circular array outside the rotating shaft. The length of the working surface of the plurality of scraper plates 87 corresponds to the width of the loop belt 82. When working, the working surface of the scraper plate 87 is parallel to the axial direction of the second rotating shaft. It should be noted that the rotation direction of the loop belt 82 is consistent with the rotation direction of the scraper plate 87.
[0048] During operation, the loop belt 82 is arranged on the second active roller 84 and the second driven roller 85. The motor drives the second active roller 84 to rotate, and the loop belt 82 drives the second driven roller 85 to rotate. The camellia seed shell mixture enters the second feed hopper 81 and falls onto the loop belt 82 on the upper side. The camellia seed shell mixture moves along with the loop belt 82 on the loop belt 82. When the camellia seed shell moves to the discharge end, the camellia seed slides off the loop belt 82, and the camellia seed is discharged. The fruit shells are still adhered to the loop belt 82 and rotate with the loop belt 82; the shaking rod 86 located at the lower end rotates continuously, and when the shaking part rotates to collide with the loop belt 82, the oil-tea fruit shells fall off the loop belt 82 due to the vibration; at this time, there are still some oil-tea fruit shells on the loop belt 82 that have not fallen off the loop belt 82, and continue to move to the scraper plate 87, and the scraper plate 87 and the loop belt 82 are gap-matched, and the oil-tea fruit shells on the loop belt 82 fall off under the action of the scraper plate 87.
[0049] The working principle of the tea seed shell sorting system is as follows:
[0050] After picking, the fresh tea fruit is dried in a hot air dryer to make it burst; the seed shell mixture after bursting enters the drum sorting machine 3 through the discharging machine 1 and the feeding elevator 2, and the slag shell at the outlet of the drum sorting machine 3 is transported to the designated point through the slag shell discharging machine 15; the first level of the drum sorting machine 1 is a 7mm gap round rod sorting, which sorts out the broken residues and fruit shells less than 7mm, and the seed shell mixture larger than 7mm enters the orifice plate sorting part 32 for further sorting; the second level of the drum sorting machine 1 is a Φ33mm diameter orifice plate sorting, and the seed shell mixture larger than 33mm at the outlet of the orifice plate sorting part 32 enters the shell breaker, and then enters the seed shell separator 14 through the return conveyor 13 for seed shell separation, and then enters the drum sorting machine 3 again;
[0051] The seed husk mixture with a diameter less than 33 mm at the outlet of the orifice plate sorting part 32 enters the vibrating spreader 5 through the conveying elevator 4. The vibrating spreader 5 evenly sends the seed husk mixture to the primary dough making belt sorter 6 to sort out part of the husk (about 70% of the husk); the seed husk mixture continues to pass through the secondary dough making belt sorter 7 to further sort out part of the husk (about 15% of the husk);
[0052] The seed shell mixture then enters the primary terry belt sorter 8 to further sort out some of the shells (about 10% shells); the seed shell mixture then enters the secondary terry belt sorter 10 to once again sort out some of the shells (about 4-5% shells), and finally the camellia seeds with a shell content of less than 1% are obtained; the separated shells are transported to the shell collection area via the shell discharging conveyor elevator 11, and the separated camellia seeds are transported to the camellia seed collection area via the camellia seed discharging conveyor elevator 12.
[0053] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
