Description

Technical Field

[0001] This utility model relates to the field of agricultural planting and processing equipment technology, and in particular to a seed harvesting device for catnip. Background Technology

[0002] Nepeta cataria is a perennial plant belonging to the genus Nepeta in the family Lamiaceae. When mature, the plant takes on a fan-shaped form, is of moderate height, and has opposite leaves covered with white downy hairs. The inflorescence is a spike-like cluster borne at the top of the main stem and branches. The fruit and seeds are mainly distributed at the branch tips and inflorescence area. The mature fruit is a small, ovoid nutlet, nearly triangular in shape, grayish-brown, about 1.7 mm long and 1 mm in diameter.

[0003] In existing technologies, catnip seeds are generally harvested by manually picking or beating them after they have been dried. Since catnip has lush stalks and each stalk bears multiple seeds, manual harvesting is time-consuming, labor-intensive, and not conducive to rapid harvesting. Utility Model Content

[0004] This invention addresses the technical problem of low efficiency in existing methods of harvesting catnip seeds by providing a catnip seed harvesting device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A seed harvesting device for catnip includes a primary conveyor belt assembly, a pressing assembly, at least two scraping assemblies, and a receiving trough. The pressing assemblies are spaced apart directly above the primary conveyor belt assembly, forming a conveying space between them for the plant stems to pass through. Each scraping assembly is located on one side of the primary conveyor belt assembly and is arranged at intervals along the conveying direction of the primary conveyor belt assembly. Each scraping assembly includes a third support, a scraping cylinder rotatably connected to the third support, a second motor with its output end coaxially driven to one end of the scraping cylinder, and multiple scraping plates, each with one end fixedly connected to the scraping cylinder. The scraping plates are spaced apart along the length of the scraping cylinder and circumferentially spaced within the scraping cylinder. The rotation plane of each scraping plate is perpendicular to the conveying direction of the primary conveyor belt assembly. The receiving trough is located below each scraping cylinder and opens upward toward each scraping cylinder.

[0007] The beneficial effects of this invention are as follows: During harvesting, the catnip plants are fed into the primary conveyor belt assembly from the feed end, with the stems of the catnip plants positioned on the primary conveyor belt assembly. The branches and leaves of the catnip plants are suspended on the side of the primary conveyor belt assembly, facing the scraping assembly, and located directly above the receiving trough. Under the continuous transmission action of the primary conveyor belt assembly, each catnip plant enters the conveying space. Simultaneously, the second motor is started, driving the scraping cylinder to rotate, which in turn drives multiple scraping blades to rotate simultaneously. The rotating scraping blades scrape the branches and leaves of the catnip plants suspended on the side of the primary conveyor belt assembly, thus... Seeds on the branches and leaves of the catnip plant fall into the receiving trough. Under the continuous conveying of the primary conveyor belt assembly, after being scraped by the scraper plates of multiple scraper assemblies, the catnip plant is sent out from the discharge end of the primary conveyor belt assembly. During the transmission process, the pressing assembly presses the stems of the catnip plant down onto the primary conveyor belt assembly to prevent the rotating scraper plates from snagging the catnip plant onto the primary conveyor belt assembly. By using this harvesting equipment, it is only necessary to feed the catnip plant into the feed end of the primary conveyor belt assembly and make the catnip plant in a preset posture, so as to improve the technical problem of low efficiency of the existing catnip seed harvesting method.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, each of the scraper blades includes a fixed plate and at least one flexible scraper blade, one end of the fixed plate is fixedly connected to the scraper cylinder, and one end of each flexible scraper blade is fixedly connected to the other end of the fixed plate.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when the scraper is scraping the seeds on the branches and leaves of the catnip plant, the flexible scraper contacts the branches and leaves and can bend in the opposite direction under the action of reaction force, reducing the possibility of the plant branches being broken due to the rotation of the scraper.

[0011] Furthermore, each scraper plate has at least two flexible scrapers, and the flexible scrapers of the same scraper plate are arranged at intervals along the conveying direction of the primary conveyor belt assembly, and a scraping space 343 is formed between two adjacent flexible scrapers.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that when using a flexible scraper to remove seeds from the branches and leaves of the catnip plant, as the flexible scraper rotates, some branches and leaves can enter the removal space 343. The adjacent flexible scrapers form a clamping and removal action on the branches and leaves, thereby improving the seed harvesting efficiency.

[0013] Furthermore, the fixed plate and the corresponding flexible scraper form an obtuse angle structure.

[0014] The beneficial effect of adopting the above-mentioned further solution is that when each scraper assembly rotates simultaneously to perform scraping operation on the catnip plants continuously conveyed by the primary conveyor belt assembly, the flexible scraper at the end of the obtuse angle structure makes contact with the plant branches and leaves in advance, and performs sequential and continuous scraping operation on the plant branches and leaves as the scraper cylinder rotates. Compared with the method where the entire surface of the scraper plate directly contacts the plant branches and leaves at the same time, the scraping effect is better.

[0015] Furthermore, the scraper assembly is provided with at least three scraper assemblies, and the opening directions of the obtuse angle structure of the scraper blades of two adjacent scraper assemblies are opposite.

[0016] The beneficial effects of adopting the above-mentioned further scheme are as follows: When each scraping assembly rotates simultaneously to scrape the catnip plants continuously conveyed by the primary conveyor belt assembly, the scraping plates of some scraping assemblies form a downward obtuse angle structure to directly scrape the upper layer of the plant branches and leaves. At the same time, the scraping plates of other scraping assemblies 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 sequential and vertical cyclic scraping action can create a continuous shaking effect on the branches and leaves, so as to ensure that the seeds are fully detached from the plant.

[0017] Furthermore, each of the scraping assemblies also includes multiple cleaning brushes with one end fixedly connected to the corresponding No. 3 bracket, and the other end of each cleaning brush extends downward toward the corresponding scraping plate, and the other end of the cleaning brush extends within the rotation range of the scraping plate.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the scraper rotates and performs scraping operation, the cleaning brush located in the rotation plane of the scraper can clean the attached materials on the scraper.

[0019] Furthermore, it also includes a support plate with one end fixedly connected to one side of the primary conveyor belt assembly, and the other end of the support plate extends toward the scraper assembly and extends within the rotation range of each of the flexible scrapers.

[0020] The beneficial effects of adopting the above-mentioned further scheme are: during the continuous conveying of catnip plants through the primary conveyor belt assembly, the support plate can support the connection between each branch and the stem of the catnip plant, thereby reducing the possibility that the entire plant will break directly from the stem under the action of the rotating scraper; during the support process of the support plate, the rotating flexible scraper will deform upon contact with the support plate.

[0021] Furthermore, the other end of the support plate is inclined downward and extends into the upper opening of the receiving groove.

[0022] The beneficial effects of adopting the above-mentioned further scheme are: the inclined support plate can guide the falling material, reducing the chance of branches and leaves getting stuck on the support plate. At the same time, when the flexible scraper rotates from the upper side to the lower side of the support plate, the guiding effect formed by the inclined support plate can reduce the deformation requirements of the flexible scraper, so that the flexible scraper only needs to undergo a small adaptive deformation to pass through the support plate and complete the material removal operation of the plant seeds.

[0023] Furthermore, the primary conveyor belt assembly includes a first support, a drive roller, a driven roller, multiple support rollers, a conveyor belt, and a first motor mounted on the first support. The two ends of the drive roller, the driven roller, and the multiple support rollers are rotatably connected to the first support, and the roller surfaces abut against the inner side of the conveyor belt. The conveyor belt is tensioned by the drive roller and the driven roller. The multiple support rollers are spaced apart on the same horizontal plane and simultaneously abut against the upper surface of the conveyor belt. The output shaft of the first motor is drivenly connected to one end of the drive roller. The pressing assembly is spaced apart directly above the conveyor belt and forms a conveying space with the conveyor belt for the plant stems to pass through.

[0024] The beneficial effects of adopting the above-mentioned further scheme are as follows: During the harvesting operation, the catnip plants are fed into the conveyor belt from the feed end, with the stems of the catnip plants positioned on the conveyor belt and the branches and leaves of the catnip plants hanging on the side of the conveyor belt facing the scraper assembly and located directly above the receiving trough. Under the continuous transmission action of the conveyor belt, each catnip plant enters the conveying space. During this process, the No. 1 motor is started to drive the drive roller to rotate, which in turn drives the tensioned conveyor belt to rotate.

[0025] Furthermore, the primary conveyor belt assembly also includes a tension roller that is rotatably connected to the first bracket at both ends. The roller surface of the tension roller abuts against the inner side of the conveyor belt, causing the upper surface of the conveyor belt to form an inclined section and a horizontal section. The roller surface of each support roller abuts against the inner side of the horizontal section. The inclined section is inclined, and the pressing assembly is spaced apart and positioned directly above the horizontal section.

[0026] The beneficial effects of adopting the above-mentioned further scheme are: during the conveying process, the inclined section serves as the feed end of the conveyor belt, which facilitates the receiving and conveying of catnip plants, so as to adjust the conveying posture of the catnip plants in advance and ensure the subsequent seed harvesting effect.

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0039] Example 1

[0040] like Figures 1 to 5A seed harvesting device for catnip includes a primary conveyor belt assembly 1, a pressing assembly 2, at least two scraper assemblies 3, and a receiving trough 4. The pressing assemblies 2 are spaced above the primary conveyor belt assembly 1, forming a conveying space 18 between them for the plant stems to pass through. Each scraper assembly 3 is located 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 scraper assembly 3 includes a third support 31 and a rotatable connection. The scraper cylinder 32 of the third bracket 31, the second motor 33 coaxially connected to one end of the scraper cylinder 32 at the output end, and multiple scraper plates 34 with one end fixedly connected to the scraper cylinder 32 are arranged at intervals along the length of the scraper cylinder 32 and at intervals around the scraper cylinder 32. The rotation plane of each scraper plate 34 is perpendicular to the transmission direction of the first-stage conveyor belt assembly 1. The receiving groove 4 is located on the lower side of each scraper cylinder 32 and opens upward toward each scraper cylinder 32.

[0041] The beneficial effects of this embodiment are as follows: During harvesting, the catnip plants are fed into the primary conveyor belt assembly 1 from the feed end, with the stems of the catnip plants positioned on the primary conveyor belt assembly 1, while the branches and leaves of the catnip plants are suspended on the side of the primary conveyor belt assembly 1 facing the scraper assembly 3, and located directly above the receiving trough 4. Under the continuous transmission action of the primary conveyor belt assembly 1, each catnip plant enters the conveying space 18. At the same time, the second motor 33 is started, driving the scraper cylinder 32 to rotate, which in turn drives multiple scraper blades 34 to rotate simultaneously. The rotating scraper blades 34 perform a scraping operation on the branches and leaves of the catnip plants suspended on the side of the primary conveyor belt assembly 1. The seeds on the branches and leaves of the catnip plant fall into the receiving trough 4. Under the continuous conveying of the primary conveyor belt assembly 1, after being scraped by the scraper plates 34 of multiple scraper assemblies 3, the catnip plant is 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 catnip plant down onto the primary conveyor belt assembly 1 to prevent the rotating scraper plates 34 from snagging the catnip plant onto the primary conveyor belt assembly 1. By using this harvesting equipment, it is only necessary to feed the catnip plant into the feed end of the primary conveyor belt assembly 1 and make the catnip plant in a preset posture, so as to improve the technical problem of low efficiency of the existing catnip seed harvesting method.

[0042] In addition, each scraper 34 is spaced apart along the length of the scraper cylinder 32, that is, a non-scraping space is formed between two adjacent scraper 34. When the catnip plant after being scraped by the scraper 34 is continuously conveyed backward by the primary conveyor belt assembly 1, the catnip plant passes through the non-scraping space to reach the rotating circumferential surface of the next scraper 34. In the non-scraping space, the catnip plant can rebound and shake under its own toughness, shaking off the seeds that have fallen or are about to fall off, thereby improving the scraping efficiency.

[0043] The pressing assembly 2 includes a second support 21, a vertical linear drive 22 mounted on the second support 21, a pressing component 23 fixedly connected to the drive end of the vertical linear drive 22, and multiple vertically arranged limiting rods 24; the vertical linear drive 22 extends vertically downward; the pressing component 23 is arranged parallel to the top of the primary conveyor belt assembly 1, and forms a conveying space 18 between it and the primary conveyor belt assembly 1 for the plant stems to pass through; the multiple limiting rods 24 are distributed at intervals, with their upper ends vertically slidingly connected to the second support 21 and their lower ends fixedly connected to the pressing component 23.

[0044] Thus, during the continuous transport of catnip plants through the primary conveyor belt assembly 1, the pressing component 23 presses down on the stems of the catnip plants.

[0045] The vertical linear drive component 22 can be a cylinder. By extending and retracting the vertical linear drive component 22, the pressing component 23 can move 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 stem of the catnip plant, ensuring smooth transmission, and ensuring that the catnip plant on the primary conveyor belt assembly 1 will not fall off the primary conveyor belt assembly 1 due to the scraping action of the scraping assembly 3.

[0046] As one of the parallel solutions in the above embodiments, the pressing component 23 is a flat plate parallel to the primary conveyor belt assembly 1. When the catnip plants are transported between the conveying spaces 18, sliding friction is formed between the catnip plants and the pressing component 23, and the primary conveyor belt assembly 1 drives the catnip plants to complete the transport operation.

[0047] As a second parallel embodiment of the above, the pressing assembly 23 includes a pressing frame 231 that is fixedly connected to the driving end of the vertical linear drive member 22 and multiple limiting rods 24, two rotating rollers 232 that are rotatably connected to the pressing frame 231, and a ring-shaped pressing belt 233; the two rotating rollers 232 are arranged parallel to each other on the inner side of the pressing belt 233 and tension the pressing belt 233; the pressing belt 233 is arranged parallel to each other directly above the primary conveyor belt assembly 1 and forms a conveying space 18 between the pressing belt assembly 1 and the primary conveyor belt assembly 1 for the plant stems to pass through.

[0048] In this embodiment, the pressing assembly 23 further includes multiple pressing rollers 234 that are spaced apart and parallel to the limiting rod 24. The multiple pressing rollers 234 are on the same horizontal plane, and their sides 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.

[0049] When the catnip plants are conveyed between the conveyor spaces 18, the pressing belt 233 presses the catnip plants down onto the primary conveyor belt assembly 1. During the conveying process, the pressing belt 233, tensioned by two rotating rollers 232, rotates under friction to ensure that the catnip plants are conveyed smoothly and quickly by the primary conveyor belt assembly 1. Furthermore, during the conveying process, under the reaction force of the catnip plants, the lower surface of the pressing belt 233, particularly the portion between the rotating rollers 232 and the pressing rollers 234, and the portion between two adjacent pressing rollers 234, adaptively indents upwards to form a space to accommodate the catnip plant stems, thereby ensuring the smooth conveying of the catnip plants.

[0050] Example 2

[0051] like Figures 1 to 4 Based on Embodiment 1, each scraper 34 includes a fixed plate 341 and at least one flexible scraper 342. One end of the fixed plate 341 is fixedly connected to the scraper cylinder 32, and one end of each flexible scraper 342 is fixedly connected to the other end of the fixed plate 341.

[0052] The beneficial effect of the preferred solution in the above embodiments is that when the scraper 34 is scraping the seeds on the branches and leaves of the catnip plant, the flexible scraper 342 contacts the branches and leaves and can bend in the opposite direction under the action of reaction force, reducing the possibility of the plant branches being broken due to the rotation of the scraper 34.

[0053] As a specific embodiment of the above, the flexible scraper 342 can be made of rubber or silicone material and undergoes adaptive deformation when subjected to the reaction force of the catnip plant.

[0054] Example 3

[0055] like Figures 2 to 4 Based on embodiments 1 and 2, each scraper 34 has at least two flexible scrapers 342, and the flexible scrapers 342 of the same scraper 34 are arranged at intervals along the conveying direction of the primary conveyor belt assembly 1, and a scraping space 343 is formed between two adjacent flexible scrapers 342.

[0056] The beneficial effect of the preferred solution in the above embodiments is that when using the flexible scraper 342 to remove seeds from the branches and leaves of the catnip plant, as the flexible scraper 342 rotates, some branches and leaves can enter the removal space 343. The adjacent flexible scrapers 342 form a clamping and removal action on the branches and leaves, thereby improving the seed harvesting efficiency.

[0057] Based on the above embodiment, a "V" shaped groove is formed at the material-plucking space 343 to increase the possibility of the catnip plant branches and leaves entering the material-plucking space 343, and the material-plucking space 343 with gradually narrowing width forms a gradually clamping and material-plucking effect on the catnip plant branches and leaves, thereby improving the material-plucking effect.

[0058] The bottom of the "V"-shaped groove formed by the material handling space 343 has an arc-shaped structure to prevent the branches and leaves of the catnip plant from entering the bottom of the groove and becoming unable to get out.

[0059] Example 4

[0060] like Figures 2 to 4 Based on embodiments 1-3, the fixed plate 341 and its corresponding flexible scraper 342 form an obtuse angle structure.

[0061] The beneficial effect of adopting the preferred solution in the above embodiments is that when each scraper assembly 3 rotates simultaneously to perform scraping operation on the catnip plants continuously conveyed by the primary conveyor belt assembly 1, the flexible scraper 342 at the end of the obtuse angle structure makes contact with the plant branches and leaves in advance, and performs sequential and continuous scraping operation on the plant branches and leaves as the scraper cylinder 32 rotates. Compared with the method where the entire surface of the scraper 34 directly contacts the plant branches and leaves at the same time, the scraping effect is better.

[0062] The included angle of an obtuse angle structure can be 110°, 120°, 130°, 135°, 140°, and 145°, etc.

[0063] Example 5

[0064] like Figures 2 to 4 Based on embodiments 1-4, the scraper assembly 3 is provided with at least three scraper plates 34 arranged on the same straight line along the conveying direction of the primary conveyor belt assembly 1, and the opening directions of the obtuse angle included structure of two adjacent scraper assemblies 3 are opposite.

[0065] The beneficial effect of the preferred scheme in the above embodiments is that when each scraping assembly 3 rotates simultaneously to scrape the catnip plants continuously conveyed by the primary conveyor belt assembly 1, the scraping plates 34 of some scraping assemblies 3 form a downward obtuse angle structure to directly scrape the upper layer of the plant branches and leaves. At the same time, the scraping plates 34 of other scraping 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 sequential and vertical cyclic scraping action can create a continuous shaking effect on the branches and leaves to ensure that the seeds are fully detached from the plant.

[0066] As one specific embodiment of the above scheme, along the conveying direction of the primary conveyor belt assembly 1, starting from the feed end of the primary conveyor belt assembly 1, such as... Figure 3 The obtuse angle structure of the odd-numbered (first, third, fifth...) scraper assembly 3 has an opening in the counterclockwise direction of the rotation of the scraper plate 34, while the obtuse angle structure of the even-numbered (second, fourth, sixth...) scraper assembly 3 has an opening in the clockwise direction of the rotation of the scraper plate 34.

[0067] When the opening of the obtuse-angled structure is in the counterclockwise direction of the rotation of the scraper plate 34, the scraper plate 34 moves downward to scrape the upper layer of plant branches and leaves; when the opening of the obtuse-angled structure is in the clockwise direction of the rotation of the scraper plate 34, the scraper plate 34 moves upward to scrape the lower layer of plant branches and leaves.

[0068] As a second specific embodiment, the opening direction of the obtuse angle structure of each scraper assembly 3 is opposite to the opening direction of one of the specific embodiments.

[0069] Example 6

[0070] like Figures 2 to 4 Based on embodiments 1-5, each scraper assembly 3 also includes multiple cleaning brushes 35 with one end fixedly connected to the corresponding No. 3 bracket 31. The other end of each cleaning brush 35 extends downward 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.

[0071] The beneficial effect of the preferred solution in the above embodiments is that when the scraper 34 rotates and performs scraping operation, the cleaning brush 35 located in the rotation plane of the scraper 34 can clean the attached material on the scraper 34.

[0072] The cleaning brush 35 can be made of rubber.

[0073] Example 7

[0074] like Figures 2 to 4 Based on embodiments 1-6, the catnip seed harvesting equipment of this utility model further includes a support plate 5 with one end fixedly connected to one side of the primary conveyor belt assembly 1, and the other end of the support plate 5 extends toward the scraper assembly 3 and extends within the rotation range of each flexible scraper 342.

[0075] The beneficial effect of the preferred scheme in the above embodiments is that, during the continuous conveying of catnip plants through the primary conveyor belt assembly 1, the support plate 5 can support the connection between each branch and the stem of the catnip plant, thereby reducing the possibility that the entire plant will break directly from the stem under the action of the rotating scraper 34; during the support process of the support plate 5, the rotating flexible scraper 342 touches the support plate 5 and deforms.

[0076] As a parallel scheme of the above embodiments, each flexible scraper 342 (rotating clockwise) with an obtuse angle structure that opens upward relative to the support plate 5 has its rotation plane spaced apart from the other end of the support plate 5, so that the flexible scraper 342 will not collide with or deform with the support plate 5 during the rotation process, so as to ensure that the flexible scraper 342 directly scrapes the branches and leaves of the catnip plant.

[0077] Example 8

[0078] like Figures 2 to 4 Based on embodiments 1-7, the other end of the support plate 5 is inclined downward and extends to the upper opening of the receiving groove 4.

[0079] The beneficial effect of the preferred solution in the above embodiments is that the inclined support plate 5 can guide the falling material, reducing the probability of branches and leaves getting stuck on the support plate 5. At the same time, when the flexible scraper 342 rotates from the upper side to the lower side of the support plate 5, the guiding effect formed by the inclined support plate 5 can reduce the deformation requirements 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 5 and complete the material removal operation of the plant seeds.

[0080] Based on the above embodiment, multiple diagonal braces are fixedly connected to the lower side of the support plate 5 to support the support plate 5 and ensure its stability.

[0081] Example 9

[0082] like Figure 1 and Figure 5 Based on embodiments 1-8, the primary conveyor belt assembly 1 includes a first support 11, a drive roller 12, a driven roller 13, multiple support rollers 14, a conveyor belt 15, and a first motor 16 mounted on the first support 11. The two ends of the drive roller 12, the driven roller 13, and the multiple support rollers 14 are rotatably connected to the first support 11, and the roller surfaces all abut against the inner side of the conveyor belt 15. The conveyor belt 15 is tensioned by the drive roller 12 and the driven roller 13. The multiple support rollers 14 are spaced apart on the same horizontal plane and simultaneously abut against the upper surface of the conveyor belt 15. The output shaft of the first motor 16 is drivenly connected to one end of the drive roller 12. The pressing assembly 2 is spaced apart directly above the conveyor belt 15 and forms a conveying space 18 with the conveyor belt 15 for the plant stems to pass through.

[0083] The beneficial effect of adopting the preferred scheme in the above embodiments is that, during the harvesting operation, the catnip plants are fed into the feed end of the conveyor belt 15, and the stems of the catnip plants are placed on the conveyor belt 15, while the branches and leaves of the catnip plants are suspended on the side of the conveyor belt 15 facing the scraper assembly 3 and located directly above the receiving trough 4, so that under the continuous transmission action of the conveyor belt 15, each catnip plant enters the conveying space 18. During this process, the No. 1 motor 16 is started to drive the drive roller 12 to rotate, which in turn drives the tensioned conveyor belt 15 to rotate.

[0084] One end of the support plate 5 is fixedly connected to the first bracket 11.

[0085] Example 10

[0086] like Figure 1 and Figure 5 Based on embodiments 1-9, the primary conveyor belt assembly 1 further includes a tension roller 17 with both ends rotatably connected to the first bracket 11. The roller surface of the tension roller 17 abuts against the inner side of the conveyor belt 15, so that 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. The pressing assembly 2 is spaced apart and positioned directly above the horizontal section 152.

[0087] The beneficial effect of adopting the preferred scheme in the above embodiments is that, during the conveying process, the inclined section 151 serves as the feed end of the conveyor belt 15, which facilitates the receiving and conveying of catnip plants, so as to pre-adjust the conveying posture of the catnip plants and ensure the subsequent seed harvesting effect.

[0088] Among them, the pressing components 23 of the pressing assembly 2 are arranged parallel and spaced above the horizontal section 152, and together with the conveyor belt 15, they form a conveying space 18 for the plant stems to pass through.

[0089] Based on the above embodiment, the outer ring side of the conveyor belt 15 is provided with multiple material troughs 153 spaced apart. During the process of conveying the catnip plants by the rotating conveyor belt 15, the material troughs 153 can form a space to accommodate the stems of the catnip plants and create a forward sliding effect on the catnip plants, ensuring that the catnip plants are smoothly and quickly conveyed backward. When the catnip plants are conveyed to the discharge end of the conveyor belt 15, the opening of the material trough 153 at the drive roller 12 opens, ensuring that the catnip plants clamped in the material trough 153 can be smoothly removed.

[0090] By opening the material container 153, when the catnip plant is placed on the inclined section 151, the material container 153 on the inclined section 151 can create a frictional effect on the catnip plant, preventing the catnip plant placed on the inclined section 151 from rolling downwards.
