[0043] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0044] Example 1

[0045] like Figures 1 to 6A processing equipment for harvesting, shelling and screening nepeta seeds, including a harvesting assembly, a shelling assembly and a screening assembly. The shelling assembly includes a shelling box 5 and a shelling screen 6 installed in the shelling box 5. The shelling box 5 has a drop port 51 at the top connected to the discharge end of the harvesting assembly, and a discharge port 52 at the bottom connected to the feed end of the screening assembly. The shelling screen 6 has a plurality of filtering holes 611 therethrough. A roller frame 53 is installed in the shelling box 5. The roller frame 53 is rotatably connected to a shelling roller 54. The roller surface of the shelling roller 54 abuts against the upper side of the shelling screen 6.

[0046] The beneficial effects of this embodiment are as follows: during the harvesting operation, the Nepeta plants are fed into the feeding end of the harvesting assembly, the seeds on the branches and leaves of the Nepeta plants are plucked off by the harvesting assembly, and are discharged into the shelling assembly for shelling of the seeds. During the shelling process, the seeds are discharged into the shelling box 5 through the drop opening 51 and fall onto the shelling screen 6. At the same time, the shelling roller 54 is rotated, and the seeds falling onto the shelling screen 6 are crushed and shelled by the rotating shelling roller 54. The shelled seeds and the finely crushed shells are discharged from the filter holes 611 of the shelling screen 6 at the same time. , and discharged into the screening assembly through the discharge port 52, and the shelled seeds and the shells are separated by the screening assembly, thereby completing the seed harvesting operation. Through this operation method, it is only necessary to add the dried nepeta plants to the harvesting assembly, and the entire harvesting operation can be completed through the subsequent harvesting assembly, shelling assembly and screening assembly, thereby improving the existing method of processing the dried nepeta plants to obtain shelled nepeta seeds. The entire processing method has the technical problems of long process time, low efficiency, and large amount of manual labor.

[0047] That is, in the present invention, the harvesting assembly is used to pluck the seeds from the branches and leaves of the Nepeta plant, the shelling assembly is used to shell the seeds, and the screening assembly is used to screen the shelled seeds.

[0048] As a specific solution of the above embodiment, the material dropping port 51 is connected to a material dropping hopper, and the material discharging port 52 is connected to a material discharging hopper.

[0049] Based on the above embodiment, a plurality of shelling grains 541 are fixedly connected to the roller surface of the shelling roller 54, so that during the shelling process, the shelling efficiency can be improved by the shelling grains 541, and a seed accommodating space can be formed between adjacent shelling grains 541 to reduce the probability of the shelled seeds being squeezed again.

[0050] Example 2

[0051] like Figures 1 to 6 On the basis of Example 1, the shelling assembly also includes a gear ring 55 and a roller driving member 56 for driving the gear ring 55 to rotate. The gear ring 55 is rotatably connected to the inner side of the shelling box 5. One end of the shelling roller 54 is rotatably connected to the roller frame 53, and the other end is fixedly connected to the inner side of the gear ring 55.

[0052] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the shelling operation is performed, the roller driving member 56 is started to drive the gear ring 55 to rotate, driving the shelling roller 54 to rotate circumferentially with the roller frame 53 as the central axis, and the schizonepeta seeds on the shelling screen 6 are crushed and shelled.

[0053] The roller driving member 56 includes a driving gear 561 and a roller driving motor 562 whose output end is coaxially fixedly connected to the driving gear 561. The driving gear 561 and the roller driving motor 562 are both installed on the inner wall of the shelling box 5. The driving gear 561 is driven to rotate by the roller driving motor 562, thereby driving the gear ring 55 to rotate.

[0054] A protective cover No. 1 563 is also fixedly connected to the inner wall of the shelling box 5 . The protective cover No. 1 563 covers the roller driving motor 562 , and its output shaft passes through and is rotatably connected to the protective cover No. 1 563 , so as to protect the roller driving motor 562 through the protective cover No. 1 563 .

[0055] An annular groove is provided on the inner wall of the shelling box 5 to rotatably mount the gear ring 55 .

[0056] Example 3

[0057] like Figures 1 to 6 On the basis of Examples 1 and 2, the shelling assembly further includes a plurality of sorting plates 57, each of which is distributed on both sides of the shelling roller 54, and one end of each of which is fixedly connected to the inner side of the gear ring 55, and the other end of each of which extends inwardly toward the roller frame 53, and each of which is fixedly connected to a plurality of inclined rods 58 at intervals, and each of which is inclined downward toward the shelling screen 6 and abuts against the shelling screen 6, and each of which is distributed on both sides of the shelling roller 54 is inclined downward in a direction away from the shelling roller 54.

[0058] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the schizonepeta seeds on the shelling screen 6 are crushed and shelled by the rotating shelling roller 54, each material sorting plate 57 rotates synchronously with the rotation of the material sorting plate 57 to flatten the material that has fallen and accumulated on the shelling screen 6, thereby reducing material accumulation. At the same time, during the rotation of each material sorting plate 57, each inclined rod 58 located in front of and behind the rotation direction of the shelling roller 54 simultaneously turns over the seeds on the shelling screen 6, thereby reducing accumulation, improving the material falling effect, and preventing the material from clogging the filter holes 611. During this process, each inclined rod 58 located behind the rotation direction of the shelling roller 54 can turn over the seeds crushed by the shelling roller 54 to prevent compaction and facilitate the next crushing and shelling operation.

[0059] On the basis of the above-mentioned embodiment, each inclined rod 58 on the same material sorting plate 57 forms an acute angle structure opening downward relative to the material sorting plate 57 , and the closer to the inner side of the gear ring 55 , the larger the acute angle.

[0060] Example 4

[0061] like Figures 1 to 6 On the basis of Examples 1-3, the shelling screen 6 includes at least three plate screens 61 and a vertical linear support member 62 installed at the bottom of the shelling box 5. The ends of each plate screen 61 are butted end to end to form an annular plate structure. Each plate screen 61 is provided with a filtering hole 611. The outer end of each plate screen 61 is rotatably connected to a screen seat 612 fixed to the inner wall of the shelling box 5. The driving end of the vertical linear support member 62 is upward and butted against the lower side of each plate screen 61 at the same time.

[0062] The beneficial effect of adopting the preferred scheme in the above embodiment is that after completing the staged shelling operation of the seeds, the vertical linear support member 62 can be recovered so that each plate screen 61 can rotate downward with its own connected screen seat 612 as the central axis under the action of its gravity, so that the retained materials on each plate screen 61 can fall completely for thorough cleaning.

[0063] On the basis of the above-mentioned embodiment, each plate screen 61 is tilted downward toward the axis of the shelling screen 6, and the tilt angle is not greater than 5°, so that the shelled seeds falling on the shelling screen 6 can slide and be flattened under the action of their gravity. At the same time, when the vertical linear support member 62 supports each plate screen 61 upward at the same time to form the shelling screen 6, the ends of adjacent plate screens 61 can form a limiting effect on each other, ensuring that the shelling screen 6 is formed in an inverted cone shape, thereby preventing adjacent plate screens 61 from being misaligned.

[0064] An avoidance hole 613 is formed at the central axis position of the shelling screen 6 to ensure smooth separation and closing of the plate screens 61 .

[0065] Example 5

[0066] like Figures 1 to 6 On the basis of Examples 1-4, the vertical linear support member 62 includes a bottom support frame 621 installed at the bottom of the shelling box 5, a vertical linear driving member 622 fixed to the bottom support frame 621, and a top support frame 623 fixedly connected to the driving end of the vertical linear driving member 622, and the top support frame 623 is simultaneously in contact with the lower side of each plate screen 61.

[0067] The beneficial effect of adopting the preferred scheme in the above embodiment is that, during the shelling operation, the driving end of the vertical linear drive member 622 supports the top support frame 623 upward, so that the top support frame 623 stably supports each plate screen 61, so that the screen surface of each plate screen 61 is simultaneously in contact with the roller surface of the shelling roller 54 and remains stable; when performing a cleaning operation, the driving end of the vertical linear drive member 622 is retracted downward, so that the top support frame 623 can be moved downward and the support for each plate screen 61 can be cancelled, so that each plate screen 61 can rotate downward with its respective connected screen seat 612 as the central axis under the action of its gravity.

[0068] The top support frame 623 is in a ring-shaped structure and is in contact with the upper end of each plate screen 61 .

[0069] Based on the above embodiment, a hanging plate 614 is fixedly connected to the lower side of each plate screen 61 near the end of the avoidance hole 613, so that when each plate screen 61 rotates downward, the hanging plate 614 abuts against the inner side of the top support frame 623 to form a hanging structure, thereby preventing each plate screen 61 from detaching from the top support frame 623.

[0070] Based on the above embodiment, the vertical linear support member 62 further includes a second protective cover 624 fixed to the bottom support frame 621, and the second protective cover 624 is provided on the vertical linear drive member 622 to protect the vertical linear drive member 622. The vertical linear drive member 622 can be a cylinder, and its piston end is slidably connected and extends out of the second protective cover 624 to be connected to the top support frame 623.

[0071] Example 6

[0072] like Figures 1 to 6 On the basis of Examples 1-5, the roller frame 53 includes a fixed frame 531 fixedly connected to the inner wall of the shelling box 5 and a central axis 532 rotatably connected to the fixed frame 531 at the upper end, the central axis 532 is arranged coaxially with the shelling screen 6, and the lower end side wall is fixedly connected to one end of the shelling roller 54.

[0073] The beneficial effect of adopting the preferred scheme in the above embodiment is that during the process of shelling the seeds, the fixed frame 531 stably supports the rotation of the shelling roller 54 through the connection of the central shaft 532, and the shelling roller 54 and the central shaft 532 rotate at the same time about the central axis of the central shaft 532, so that the seeds falling onto the shelling screen 6 are crushed and shelled by the rotating shelling roller 54.

[0074] Based on the above embodiment, the lower end of the central shaft 532 extends into the avoidance hole 613 to block the avoidance hole 613 and prevent the materials of each plate screen 61 from falling directly from the avoidance hole 613. There is a gap between the central shaft 532 and the side wall and the hole wall of the avoidance hole 613 to form a falling space for the shelled seeds to fall.

[0075] Example 7

[0076] like Figure 1 , Figures 7 to 11 On the basis of embodiments 1-6, the harvesting assembly includes a primary conveyor belt assembly 1, a pressing assembly 2, at least two scraping assemblies 3 and a material receiving trough 4. The pressing assembly 2 is arranged at intervals just above the primary conveyor belt assembly 1, and a conveying space 18 for plant stems to pass through is formed between the primary conveyor belt assembly 1 and the primary conveyor belt assembly 1. Each scraping assembly 3 is arranged on one side of the primary conveyor belt assembly 1 and is arranged at intervals along the conveying direction of the primary conveyor belt assembly 1. Each scraping assembly 3 includes a third bracket 31, which is rotatably connected to the third bracket. The scraper barrel 31, the No. 2 motor 33 whose output end is coaxially connected to one end of the scraper barrel 32, and multiple scraper plates 34 whose one ends are fixedly connected to the scraper barrel 32, each scraper plate 34 is arranged at intervals along the length direction of the scraper barrel 32, and is arranged at intervals on the scraper barrel 32 in the circumferential direction, and the rotation plane of each scraper plate 34 is perpendicular to the transmission direction of the primary conveyor belt assembly 1, the material receiving trough 4 is located at the lower side of each scraper barrel 32, and at the same time opens upward toward each scraper barrel 32, and the material receiving trough 4 is connected to the drop port 51.

[0077] The beneficial effect of adopting the preferred scheme in the above embodiment is that during the harvesting operation, the nepeta plants are fed in from the feeding end of the primary conveyor belt assembly 1, and the stems of the nepeta plants are located on the primary conveyor belt assembly 1, while the branches and leaves of the nepeta plants are suspended on the side of the primary conveyor belt assembly 1 toward the scraper assembly 3 and are located directly above the receiving trough 4, so that under the continuous transmission action of the primary conveyor belt assembly 1, each nepeta plant enters the conveying space 18, and at the same time, the No. 2 motor 33 is started to drive the scraper barrel 32 to rotate, driving the multiple scraper plates 34 to rotate at the same time, and the rotating scraper plates 34 form a scraping operation for the branches and leaves of the nepeta plants suspended on the side of the primary conveyor belt assembly 1, so that the nepeta The seeds on the branches and leaves of the plant fall into the receiving trough 4 and are input into the shelling box 5 through the drop port 51. Under the continuous conveying of the primary conveyor belt assembly 1, after the scraping operation of the scraper plates 34 of multiple scraper assemblies 3, the nepeta plants are sent out from the discharge end of the primary conveyor belt assembly 1. During the transmission process, the pressing assembly 2 presses the stems of the nepeta plants down on the primary conveyor belt assembly 1 to prevent the rotating scraper plates 34 from hanging and falling the nepeta plants on the primary conveyor belt assembly 1. By using the harvesting equipment, it is only necessary to feed the nepeta plants into the feeding end of the primary conveyor belt assembly 1 and make the nepeta plants be in a preset posture, so as to improve the technical problem of low efficiency of the existing nepeta seed harvesting method.

[0078] In addition, each scraper plate 34 is arranged at intervals along the length direction of the scraper barrel 32, that is, a non-scraping space is formed between two adjacent scraper plates 34. When the nepeta plant after being scraped by the scraper plate 34 is continuously transported backward by the primary conveyor belt assembly 1, the nepeta plant passes through the non-scraping space to reach the rotating circular surface where the next scraper plate 34 is located. In the non-scraping space, the nepeta plant can rebound and shake due to its own toughness, and shake off the seeds that have fallen off or are about to fall off, thereby improving the scraping efficiency.

[0079] On the basis of the above-mentioned embodiment, the bottom of the material receiving trough 4 is an inclined slope, and an opening is formed through the inclined bottom of the material receiving trough 4 to allow the material in the material receiving trough 4 to fall down.

[0080] A horizontal No. 1 conveyor belt 41 is arranged below the receiving trough 4, the feeding end of the No. 1 conveyor belt 41 is located directly below the through opening at the bottom of the receiving trough 4, and the discharging end of the No. 1 conveyor belt 41 is connected to the inclined No. 2 conveyor belt 42, the feeding end of the No. 2 conveyor belt 42 is located at the discharging end of the No. 1 conveyor belt 41, and the discharging end of the No. 2 conveyor belt 42 is connected to the drop opening 51. The materials falling into the receiving trough 4 are transferred to the shelling box 5 through the drop opening 51 by the No. 1 conveyor belt 41 and the No. 2 conveyor belt 42.

[0081] In the embodiment of the present invention, conveyor belt No. 1 41 and conveyor belt No. 2 42 are both well-known technologies to those skilled in the art, and both include a mounting frame, an active roller rotatably connected to the mounting frame, a driven roller kinetically connected to the mounting frame, a motor whose output shaft is connected to the active roller, and a material belt tensioned by the active roller and the driven roller. The active roller is driven to rotate by the motor, so that the tensioned material belt can rotate, thereby realizing material transmission.

[0082] Among them, the material pressing assembly 2 includes a No. 2 bracket 21, a vertical linear drive 22 installed on the No. 2 bracket 21, a material pressing component 23 fixedly connected to the driving end of the vertical linear drive 22, and a plurality of vertically arranged limit rods 24; the vertical linear drive 22 extends vertically downward; the material pressing component 23 is arranged in parallel just above the primary conveyor belt assembly 1, and forms a conveying space 18 for the plant stems to pass through between the primary conveyor belt assembly 1; a plurality of limit rods 24 are distributed at intervals, the upper ends are vertically slidably connected to the No. 2 bracket 21, and the lower ends are fixedly connected to the material pressing component 23.

[0083] In this way, during the continuous transmission of the Nepeta plants by the primary conveyor belt assembly 1 , the pressing assembly 23 presses down on the stems of the Nepeta plants.

[0084] Among them, the vertical linear drive member 22 can adopt a cylinder. Through the vertical extension and retraction of the vertical linear drive member 22, the pressing component 23 can be moved vertically toward or away from the primary conveyor belt assembly 1 to change the width of the conveying space 18, thereby changing the pressure of the pressing component 23 on the stems of the nepeta plants, ensuring smooth transmission, and ensuring that the nepeta plants on the primary conveyor belt assembly 1 will not fall off the primary conveyor belt assembly 1 due to the scraping action of the scraper assembly 3.

[0085] As one of the parallel schemes of the above-mentioned embodiment, the pressing component 23 is a flat plate parallel to the primary conveyor belt assembly 1. When the Nepeta plants are transported between the conveying space 18, sliding friction is formed between the Nepeta plants and the pressing component 23, and the primary conveyor belt assembly 1 drives the Nepeta plants to complete the transmission operation.

[0086] As the second parallel scheme of the above-mentioned embodiment, the pressing assembly 23 includes a pressing frame 231 which is fixedly connected to the driving end of the vertical linear driving member 22 and multiple limit rods 24, two rotating rollers 232 rotatably connected to the pressing frame 231, and a ring-shaped pressing belt 233; the two rotating rollers 232 are arranged in parallel on the inner side of the pressing belt 233, and the pressing belt 233 is tensioned; the pressing belt 233 is arranged in parallel just above the primary conveyor belt assembly 1, and a conveying space 18 for the plant stems to pass through is formed between the pressing belt 233 and the primary conveyor belt assembly 1.

[0087] In this embodiment, the pressing assembly 23 also includes a plurality of pressing rollers 234 that are spaced apart and parallel to the limiting rod 24. The plurality of pressing rollers 234 are located on the same horizontal plane, and the side surfaces simultaneously abut against the inner sides of the upper and lower belt surfaces of the pressing belt 233 to support the belt surface of the pressing belt 233.

[0088] When the nepeta plants are transported between the conveying spaces 18, the pressing belt 233 presses the nepeta plants down onto the primary conveyor belt assembly 1; during the transport of the nepeta plants, the pressing belt 233, which is tightened by the two rotating rollers 232, rotates under the friction force to ensure that the nepeta plants are smoothly and quickly transported by the primary conveyor belt assembly 1. In addition, during the transport, under the reaction force of the nepeta plants, the lower belt surface of the pressing belt 233 and the belt portion between the rotating roller 232 and the pressing roller 234, and the belt portion between two adjacent pressing rollers 234 are adaptively recessed upward to form a space for accommodating the stems of the nepeta plants, thereby ensuring that the nepeta plants are smoothly transported.

[0089] Example 8

[0090] like Figures 7 to 11 On the basis of Examples 1-7, each scraper plate 34 includes a fixed plate 341 and at least one flexible scraper plate 342 , one end of the fixed plate 341 is fixedly connected to the scraper barrel 32 , and one end of each flexible scraper plate 342 is fixedly connected to the other end of the fixed plate 341 .

[0091] The beneficial effect of adopting the preferred scheme in the above embodiment is that when the scraper plate 34 is scraping the seeds on the branches and leaves of the Nepeta plant, the flexible scraper plate 342 contacts the branches and leaves and can form a reverse bend under the action of the reaction force, thereby reducing the possibility of breaking the plant branches due to the rotation of the scraper plate 34.

[0092] On the basis of the above embodiment, at least two flexible scrapers 342 are provided for each scraper plate 34, and each flexible scraper plate 342 of the same scraper plate 34 is arranged at intervals along the conveying direction of the primary conveyor belt assembly 1, and a material removal space 343 is formed between two adjacent flexible scrapers 342. When the seeds on the branches and leaves of the Nepeta plant are removed by the flexible scraper plates 342, as the flexible scraper plates 342 rotate, part of the branches and leaves can enter the material removal space 343, and the branches and leaves are clamped and removed by the adjacent flexible scrapers 342, so as to improve the seed harvesting efficiency.

[0093] A "V"-shaped groove is formed at the feeding space 343 to increase the possibility of the branches and leaves of the nepeta plant entering the feeding space 343, and the gradually narrowing width of the feeding space 343 is used to gradually clamp and feed the branches and leaves of the nepeta plant, thereby improving the feeding effect. The bottom of the "V"-shaped groove formed by the feeding space 343 is an arc surface structure to prevent the branches and leaves of the nepeta plant from entering the bottom of the groove and being unable to escape.

[0094] On the basis of the above embodiment, at least three scraper assemblies 3 are provided, and the opening directions of the obtuse angle structures of the scraper plates 34 of two adjacent scraper assemblies 3 arranged on the same straight line along the conveying direction of the primary conveyor belt assembly 1 are opposite. When each scraper assembly 3 rotates simultaneously to carry out the scraping operation on the Nepeta plants continuously conveyed by the primary conveyor belt assembly 1, the scraper plates 34 of some scraper assemblies 3 form a downward obtuse angle structure to directly scrape the upper layer of the plant branches and leaves, and at the same time, the scraper plates 34 of other scraper assemblies 3 form an upward obtuse angle structure to directly scrape the lower layer of the plant branches and leaves, thereby improving the scraping effect; in this way, the cyclic scraping action of scraping in sequence and up and down can form a continuous shaking effect on the branches and leaves to ensure that the seeds are fully detached from the plant.

[0095] Each scraper assembly 3 further includes a plurality of cleaning brushes 35, one end of which is fixedly connected to the corresponding No. 3 bracket 31, and the other end of each cleaning brush 35 extends downwardly and obliquely toward the corresponding scraper plate 34, and the other end of the cleaning brush 35 extends within the rotation range of the scraper plate 34. When the scraper plate 34 rotates and performs the scraping operation, the cleaning brush 35 located in the rotation plane of the scraper plate 34 can clean the attached objects on the scraper plate 34.

[0096] On the basis of the above embodiment, the harvesting assembly further includes a support plate 19 having one end fixedly connected to one side of the primary conveyor belt assembly 1, and the other end of the support plate 19 extends toward the scraper assembly 3 and extends within the rotation range of each flexible scraper 342. In the process of continuously conveying the nepeta plants through the primary conveyor belt assembly 1, the support plate 19 can support the connection between each branch and the stem of the nepeta plant to reduce the possibility that the entire plant is directly broken from the stem under the action of the rotating scraper plate 34; in the process of supporting the support plate 19, the rotating flexible scraper 342 touches the support plate 19 and deforms.

[0097] The other end of the support plate 19 is tilted downward and extends to the upper opening of the receiving trough 4. The tilted support plate 19 can guide the falling of the material, reducing the probability of branches and leaves being retained on the support plate 19. At the same time, when the flexible scraper 342 rotates from the upper side of the support plate 19 to the lower side, the guiding effect formed by the tilted support plate 19 can reduce the deformation requirement of the flexible scraper 342, so that the flexible scraper 342 only needs to undergo a small adaptive deformation to pass through the support plate 19 and complete the material removal operation for the plant seeds.

[0098] On the basis of the above embodiment, the first-stage conveyor belt assembly 1 includes a No. 1 bracket 11, an active roller 12, a driven roller 13, a plurality of support rollers 14, a conveyor belt 15 and a No. 1 motor 16 installed on the No. 1 bracket 11. Both ends of the active roller 12, the driven roller 13 and the plurality of support rollers 14 are rotatably connected to the No. 1 bracket 11, and the roller surfaces are all in contact with the inner side of the conveyor belt 15. The conveyor belt 15 is tensioned on the active roller 12 and the driven roller 13. The plurality of support rollers 14 are arranged at intervals on the same horizontal plane and simultaneously in contact with the upper belt surface of the conveyor belt 15. The output shaft of the No. 1 motor 16 is drivingly connected to one end of the active roller 12. The pressing assembly 2 is arranged at intervals just above the conveyor belt 15 and forms a conveying space 18 with the conveyor belt 15 for the plant stems to pass through. During the harvesting operation, the nepeta plants are fed in from the feeding end of the conveyor belt 15, and the stems of the nepeta plants are located on the conveyor belt 15, while the branches and leaves of the nepeta plants are hung on the side of the conveyor belt 15 toward the scraper assembly 3 and are located directly above the receiving trough 4, so that under the continuous transmission action of the conveyor belt 15, each nepeta plant enters the conveying space 18. During this process, the No. 1 motor 16 is started to drive the active roller 12 to rotate, which can drive the tensioned conveyor belt 15 to rotate.

[0099] The primary conveyor belt assembly 1 also includes a tensioning roller 17 rotatably connected to the first bracket 11 at both ends, the roller surface of the tensioning roller 17 abuts against the inner side of the conveyor belt 15, and the upper belt surface of the conveyor belt 15 forms an inclined section 151 and a horizontal section 152, the roller surface of each support roller 14 abuts against the inner side of the horizontal section 152, and the pressing assembly 2 is arranged at intervals just above the horizontal section 152. During the conveying process, the inclined section 151 serves as the feed end of the conveyor belt 15, which is convenient for receiving the Nepeta plants to be conveyed, so as to pre-adjust the conveying posture of the Nepeta plants and ensure the subsequent seed harvesting effect.

[0100] A plurality of material troughs 153 are provided at intervals on the outer ring side of the belt surface of the conveyor belt 15. In the process of conveying the nepeta plants by the rotating conveyor belt 15, the material troughs 153 can form a space for accommodating the stems of the nepeta plants and form a forward sliding effect on the nepeta plants, ensuring that the nepeta plants are smoothly and quickly conveyed backward. When the nepeta plants are transferred to the discharge end of the conveyor belt 15, the opening of the material trough 153 at the active roller 12 opens, ensuring that the nepeta plants clamped in the material trough 153 can be smoothly released.

[0101] By opening the material receiving groove 153 , when the Nepeta plant is placed on the inclined section 151 , the material receiving groove 153 on the inclined section 151 can form a friction effect on the Nepeta plant, thereby preventing the Nepeta plant placed on the inclined section 151 from rolling downward.

[0102] Example 9

[0103] like Figure 1 , Figure 12 to Figure 14 On the basis of Embodiments 1-8, the screening assembly includes a screening box 7, a blowing assembly 8 installed on the side wall of the screening box 7, and a dust suction assembly 9 installed on the top of the screening box 7. The top of the screening box 7 is provided with a feed inlet 71 and a dust suction inlet 72. The feed inlet 71 is connected to the discharge port 52. A primary screening plate 73 and a plurality of secondary screening plates 74 are installed in the screening box 7. The primary screening plate 73 and each secondary screening plate 74 are arranged at intervals in the upper and lower sides. The primary screening plate 73 and each secondary screening plate 74 are arranged at an angle, and the primary screening plate 73 and the adjacent secondary screening plates 74 and the adjacent two secondary screening plates 74 are arranged at an angle. The inclination directions of the screening plates 74 are opposite, and the primary screening plate 73 and each secondary screening plate 74 are provided with sieve holes, and the aperture of each sieve hole decreases in sequence according to the top-down arrangement order of the primary screening plate 73 and each secondary screening plate 74 where it is located. A plurality of discharge pipes 75 are also fixed to the side wall of the screening box 7, and each discharge pipe 75 is respectively connected to the lower end of the primary screening plate 73 and the lower end of each secondary screening plate 74, the air outlet end of the blowing assembly 8 faces the upper side of the primary screening plate 73, the feed port 71 is located directly above the primary screening plate 73, and the inlet end of the dust suction assembly 9 is connected to the dust suction port 72.

[0104] The beneficial effect of the preferred scheme in the above embodiment is that, during screening, the shelled nepeta seeds are added into the screening box 7 from the feed port 71, and the nepeta seeds fall downward through the feed port 71 to the upper side of the screening side of the primary screening plate 73. At the same time, the blowing component 8 and the dust suction component 9 are started to blow the nepeta seeds falling in front of the blowing component 8, and the lighter impurities in the nepeta seeds are quickly blown away and blown to the primary screening plate 73, and the running dust suction component 9 sucks out the lighter impurities, completing the impurity separation. The heavier Nepeta seeds fall onto the primary screening plate 73 and are screened, the larger seeds are guided to the discharge pipe 75 connected to the lower end of the primary screening plate 73 through the primary screening plate 73, and the smaller seeds fall toward the secondary screening plate 74 through the sieve holes of the primary screening plate 73, and this cycle continues until they are screened in sequence by multiple secondary screening plates 74, completing the step-by-step separation operation of the Nepeta seeds and separating the impurities in the Nepeta seeds, thereby improving the technical problem of poor multi-stage screening effect of the existing separation equipment.

[0105] The bottom wall of the screening box 7 is inclined downward and opened downward to discharge the material screened by the lower secondary screening plate 74. During the screening process, containers or container belts can be set at the discharge ends of the plurality of discharge pipes 75 and the lower end opening of the screening box 7 for timely storage.

[0106] The vertical plane formed by the lower opening of the feed port 71 is located in front of the blowing assembly 8 to ensure that the blowing assembly 8 blows air on the seeds falling from the feed port 71 .

[0107] A horizontal No. 1 conveyor belt 41 is also provided below the discharge port 52, the feed end of the No. 1 conveyor belt 41 is located directly below the through opening at the bottom of the receiving trough 4, and the discharge end of the No. 1 conveyor belt 41 is connected to the inclined No. 2 conveyor belt 42, the feed end of the No. 2 conveyor belt 42 is located at the discharge end of the No. 1 conveyor belt 41, and the discharge end of the No. 2 conveyor belt 42 is connected to the feed port 71. The materials falling into the receiving trough 4 are transferred to the screening box 7 through the feed port 71 by the No. 1 conveyor belt 41 and the No. 2 conveyor belt 42.

[0108] In this embodiment, a plurality of mounting openings 76 are provided on the side wall of the screening box 7 , and each mounting opening 76 is connected to the lower end of the primary screening plate 73 and the lower end of each secondary screening plate 74 , respectively, so that the feed end of each discharge pipe 75 can be installed at the corresponding mounting opening 76 .

[0109] A plurality of inclined grooves 761 are also provided on the inner wall of the screening box 7, and the lower ends of the inclined grooves 761 are connected to the mounting openings 76 one by one, so that the primary screening plate 73 and the secondary screening plates 74 can be installed in the corresponding inclined grooves 761 through the mounting openings 76, thereby realizing the disassembly and assembly operations of the lower ends of the primary screening plates 73 and the secondary screening plates 74.

[0110] Based on the above embodiment, springs 762 are fixedly connected to the lower side of the primary screening plate 73 and the lower sides of each secondary screening plate 74, and the upper end of each spring 762 is correspondingly fixedly connected to the primary screening plate 73 and each secondary screening plate 74, and the lower end abuts against the bottom of the inclined groove 761.

[0111] When the material falls on the primary screening plate 73 or each secondary screening plate 74, the impact force of the falling seeds causes slight vibration of the corresponding primary screening plate 73 or each secondary screening plate 74, so as to reduce the possibility of seeds accumulating on the plate surface through the vibration, thereby improving the filtering and screening effect.

[0112] Example 10

[0113] Figure 12 to Figure 14 Based on Examples 1-9, the upper end of the primary screening plate 73 is higher than the height of the blowing assembly 8.

[0114] The beneficial effect of adopting the preferred scheme in the above embodiment is that while the lighter impurities in the Nepeta seeds are quickly blown toward the primary screening plate 73 by the blowing component 8, the lighter seeds in the Nepeta seeds are synchronously blown toward the primary screening plate 73. At this time, since the upper end of the primary screening plate 73 is higher than the height of the blowing component 8, the upper end of the primary screening plate 73 blocks the seeds to reduce the possibility of the seeds being sucked out by the dust suction component 9, reduce the seed loss rate, and improve the separation effect.

[0115] Based on the above embodiment, the upper end of the primary screening plate 73 and the dust suction port 72 are respectively located in two parallel and spaced vertical planes. The dust suction port 72 forms a wind selection path for impurities to pass through compared to the primary screening plate 73. While the seeds are blocked by the upper end of the primary screening plate 73, the seeds passing through the upper end of the primary screening plate 73 can be separated from the impurities at the wind selection path by utilizing the gravity of the seeds themselves and the blocking effect of the inner wall at the top of the screening box 7, so as to further reduce the possibility of seeds being sucked out by the dust suction assembly 9.

[0116] A falling space for materials to fall is formed between the upper end of the primary screening plate 73 and the inner wall of the screening box 7, the dust suction port 72 is located directly above the falling space, and the uppermost secondary screening plate 74 is located directly below the falling space. When the seeds are separated from the impurities at the wind selection path, the seeds can fall from the falling space onto the uppermost secondary screening plate 74 for subsequent screening operations, thereby improving the seed screening rate and reducing the possibility of seeds being directly sucked out by the dust suction component 9.

[0117] On the basis of the above embodiment, the blowing assembly 8 includes a blower 81 and an air guide pipe 82 whose air inlet end is connected to the air outlet end of the blower 81, and the air outlet end of the air guide pipe 82 extends into the screening box 7 and opens horizontally toward the primary screening plate 73. During screening, the blower 81 is started, and the wind is introduced from the air guide pipe 82 into the screening box 7 and toward the primary screening plate 73, blowing the nepeta seeds falling in front of the air guide pipe 82, and the lighter impurities in the nepeta seeds are quickly blown away and blown toward the primary screening plate 73.

[0118] The blowing assembly 8 also includes a blowing pipe 83 with closed ends, the blowing pipe 83 is horizontally arranged and the middle side wall is connected to the air outlet end of the air guide pipe 82, and the side wall of the blowing pipe 83 is penetrated with a plurality of blowing ports 831 all opening horizontally toward the primary screening plate 73; and the feed port 71 extends along the length direction of the blowing pipe 83. During screening, the blower 81 is started, and the wind is introduced into the blowing pipe 83 through the air guide pipe 82, and is blown out horizontally toward the primary screening plate 73 through each blowing port 831 of the blowing pipe 83 at the same time. In this process, the wind blown out horizontally from each blowing port 831 at the same time forms a wind curtain to ensure that the material falling from the feed port 71 is blown away, so that the impurities in the material are fully blown away from the seeds.

[0119] On the basis of the above embodiment, the dust collection component 9 includes a dust collection pipe 91 whose inlet end is connected to the dust collection port 72, a dust collector 92 whose inlet end is connected to the outlet end of the dust collection pipe 91, a dust guide pipe 93 whose inlet end is connected to the outlet end of the dust collector 92, and a dust collection box 94 connected to the outlet end of the dust guide pipe 93. When the dust collection component 9 is used to suck out the impurities separated from the material, the dust collector 92 is started, and the dust collector 92 sucks the impurities from the dust collection port 72, the dust collection pipe 91, the dust collector 92 and the dust guide pipe 93 into the dust collection box 94 in sequence, and the impurities are stored by the dust collection box 94 for centralized processing.

[0120] The dust collection assembly 9 also includes a check valve 95 arranged on the dust guide pipe 93. The dust collection box 94 is used to store dust collection liquid, and the outlet end of the dust guide pipe 93 extends below the liquid surface, so that the dust collection liquid added to the dust collection box 94 can absorb impurities and dust in the seed screening process, reduce the dust in the screening box 7, and prevent the liquid in the dust collection box 94 from flowing back and affecting the vacuum cleaner 92 through the check valve 95.

[0121] Based on the above embodiment, a feed hopper 77 is further included, which includes a vertical pipe 771 arranged vertically and an inclined pipe 772 whose upper end is connected to the lower end of the vertical pipe 771. The inclined pipe 772 is arranged obliquely, and its lower end is connected to the feed port 71. During screening, the schizonepeta seeds are added into the vertical pipe 771, and the schizonepeta seeds are introduced into the screening box 7 through the guidance of the inclined pipe 772. The inclined inclined pipe 772 can reduce the speed of the seeds falling, reduce the possibility that the seeds are piled up, and cause the blowing assembly 8 to fail to fully blow away the impurities in the seeds.

[0122] The width of the inclined tube 772 gradually increases from the upper end to the lower end, and the width of the feed port 71 is equal to the width of the lower end of the inclined tube 772. The inner wall of the inclined tube 772 is fixedly connected with a plurality of guide plates 773. Each guide plate 773 is arranged obliquely, and the upper end extends toward the middle of the width direction of the inclined tube 772, and the lower end extends toward the two ends of the width direction of the inclined tube 772. The width of the inclined tube 772 gradually increases from the upper end to the lower end, which relatively increases the area formed by the seeds falling in front of the blowing assembly 8, and when the seeds fall from the inclined tube 772, each guide plate 773 can guide the seeds to the two ends of the width direction of the inclined tube 772, so that the seeds are evenly distributed and fall in front of the blowing assembly 8 in a dispersed manner, thereby ensuring that the blowing assembly 8 fully blows away the impurities mixed in the seeds.
