Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a perilla leaf harvester with an automatic bundling and packaging function. Background Technology

[0002] Perilla is a plant widely used in the food and medical industries, and its leaves have high economic value. Traditional perilla leaf harvesting mainly relies on manual picking, which involves pinching off the top and pruning the leaves to allow the perilla to grow better. Although the leaves picked by pinching off the top and pruning the leaves are relatively intact, the harvesting efficiency is low and the labor intensity is high.

[0003] Currently, there are machines that harvest perilla leaves using perilla leaf harvesters. However, these machines remove the perilla leaves from the rootstock during harvesting in the field, and the remaining rootstock still needs to be removed manually. Moreover, perilla rootstock has medicinal value just like the leaves, so harvesting only the leaves would result in some waste. Furthermore, existing harvesting machines only have the function of harvesting and do not have a baling device, so the baling must be done separately later. Summary of the Invention

[0004] The purpose of this invention is to provide a perilla leaf harvester with an automatic bundling and packaging function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A perilla leaf harvester with automatic bundling and packaging function includes a machine body, a harvesting mechanism, a separating mechanism, a sorting mechanism, and a packaging mechanism. The machine body is fastened to the harvesting mechanism, the separating mechanism, and the sorting mechanism respectively, and the packaging mechanism is provided on the machine body.

[0006] The machine body serves to support the entire harvester. The harvesting mechanism, separating mechanism, and sorting mechanism are fixed to the machine body. The harvesting mechanism is used to cut perilla leaves and transport them to the sorting mechanism. The separating mechanism is used to separate the perilla roots and leaves and to recycle the roots. The sorting mechanism is used to sort and arrange the randomly placed leaves. The packing mechanism is used to bundle and pack the sorted perilla leaves.

[0007] Furthermore, the machine body includes a frame, a base plate, and wheels. The frame and the base plate are fastened together, and the frame and the wheels are rotatably connected. The frame is fastened together with the harvesting mechanism, the separating mechanism, and the sorting mechanism, respectively. A packing mechanism is provided on the base plate.

[0008] The frame is used to fix the harvesting mechanism, separating mechanism and sorting mechanism. The wheels are used to control the forward, backward and turning of the entire harvester. The base plate is fixed to the frame and is used to support the baling mechanism.

[0009] Furthermore, the harvesting mechanism includes a cutting assembly, a main conveying assembly, and detectors. The cutting assembly is fastened to the frame, the main conveying assembly is rotatably connected to the frame, and several sets of detectors are provided, with each set of detectors being fastened to the frame.

[0010] The cutting assembly is located at the front of the frame. The cutting assembly is used to cut off a portion of the rootstock with leaves. The cut perilla leaves are separated by a separation mechanism. The separated perilla leaves are transported to the sorting mechanism by the main conveyor assembly. The detector is used to detect the position of the lowest leaf on the rootstock, thereby adjusting the cutting height and improving cutting efficiency.

[0011] Furthermore, the cutting assembly includes a cutter, a cutting motor, a first transmission roller, a second conveying roller, a telescopic rod, a first transmission belt, a second transmission belt, a first support frame, and a second support frame. The cutting motor is fixedly connected to the frame, the output end of the cutting motor is fixedly connected to the first transmission roller, the first support frame is fixedly connected to the frame, the first support frame is rotatably connected to the first transmission roller, the first transmission roller and the first transmission belt are in frictional contact, the first transmission belt and the second conveying roller are in frictional contact, the second conveying roller and the first support frame are rotatably connected, the second conveying roller and the second transmission belt are in frictional contact, the second transmission belt and the telescopic rod are in frictional contact, the telescopic rod and the cutter are each provided with several sets, the upper end of the telescopic rod is fixedly connected to the cutter, the second support frame is provided with several sets, the several sets of second support frames are fixedly connected to the frame, and the second support frame and the telescopic rod are rotatably connected.

[0012] The cutter is used to cut perilla leaves. The cutting motor is mounted on the frame and is a switch that controls the rotation of the cutter. The output torque of the cutting motor drives the first transmission roller to rotate. The first transmission roller, through contact with the first transmission belt and the first transmission belt, and the second transmission roller, drives the second transmission roller to rotate. The second transmission roller, through contact with the second transmission belt and the second transmission belt, and the second transmission belt, and the telescopic rod, drives the telescopic rod to rotate. The upper end of the telescopic rod is fixed to the cutter. Therefore, the telescopic rod drives the cutter to rotate, thereby cutting the perilla leaves. The first support frame is fixed to the frame and supports the first transmission roller and the second transmission roller. Several sets of telescopic rods and cutters are provided to cut multiple rows of perilla leaves, improving cutting efficiency. The second support frame is fixed to the frame and supports the telescopic rod.

[0013] Furthermore, the main conveying assembly includes a blade conveyor belt, a conveyor motor, a main conveyor roller, a third transmission belt, and a third transmission roller. The conveyor motor is fastened to the frame, the output end of the conveyor motor is fastened to the third transmission roller, the third transmission roller and the third transmission belt are in frictional contact, and there are two sets of main conveyor rollers. One set of main conveyor rollers is in frictional contact with the third transmission belt, and the two sets of main conveyor rollers are in frictional contact with the blade conveyor belt. The two sets of main conveyor rollers are rotatably connected to the frame.

[0014] The conveyor motor is fixed to the frame. The output torque of the conveyor motor drives the third transmission roller to rotate. The third transmission roller drives the main conveyor roller to rotate through contact with the third transmission belt and the contact between the third transmission belt and the main conveyor roller. The frame supports the two sets of main conveyor rollers. When the two sets of main conveyor rollers rotate, they drive the blade conveyor belt to rotate. The perilla leaves are conveyed through the blade conveyor belt and enter the sorting mechanism when they reach the end.

[0015] Furthermore, the separation mechanism includes a secondary conveying assembly, a pressing plate, a guide plate, and a root and stem collection frame. The secondary conveying assembly is located on one side of several sets of cutters, and the guide plate is located on the other side of several sets of cutters. The secondary conveying assembly is fastened to the frame, the pressing plate is fastened to the frame, the secondary conveying assembly passes through the pressing plate, the guide plate is arranged in an arc shape, the guide plate is fastened to the frame, and the root and stem collection frame is located at the outlet end of the secondary conveying assembly and is fastened to the frame.

[0016] The secondary conveyor assembly is fixed to the frame. After being cut by the cutter, the perilla leaves enter the secondary conveyor assembly, which clamps the perilla roots and stems for transport. During transport, the front end of the perilla leaves contacts the guide plate, which is arranged in an arc. As the perilla leaves pass through the guide plate, the front end bends in the transport direction, causing the perilla leaves to face the extrusion plate. The bent front end of the perilla leaves enters the extrusion plate. When passing through the extrusion plate, since the perilla leaves face the same direction as the transport direction, they are squeezed by the extrusion plate. The leaves are subjected to a force opposite to the transport direction, thus separating from the roots and stems. The leaves fall onto the leaf conveyor belt for transport, while the roots and stems continue to be transported with the secondary conveyor assembly. After reaching the end, they fall into the root and stem collection box.

[0017] Furthermore, the auxiliary conveying assembly includes a clamping conveyor belt, a first rotating shaft, a clamping motor, a fourth transmission belt, a third support frame, a fourth support frame, and a second rotating shaft. Two sets of clamping conveyor belts are provided, each with a groove on its outer ring, arranged at an angle. The third and fourth support frames are respectively fixedly connected to the frame. The third support frame is fixedly connected to the guide plate, and the fourth support frame is fixedly connected to the clamping motor. Two sets of first rotating shafts and two sets of second rotating shafts are provided, as are two sets of fourth transmission belts. One set of fourth transmission belts is in frictional contact with two sets of first rotating shafts, and the other set is in frictional contact with two sets of second rotating shafts. The two sets of first rotating shafts are rotatably connected to the fourth support frame, and the two sets of second rotating shafts are rotatably connected to the third support frame. The output end of the clamping motor is fixedly connected to one set of first rotating shafts, and the clamping conveyor belt is in frictional contact with both one set of first rotating shafts and one set of second rotating shafts.

[0018] Because the cutter rotates counterclockwise, the cut perilla root faces the clamping conveyor belt. The groove above the clamping conveyor belt is arranged at an angle so that the perilla head faces the transport direction. The fourth support frame and the frame are fixed, and the clamping motor is fixed on the fourth support frame. The output torque of the clamping motor drives the lower first rotating shaft to rotate. The lower first rotating shaft rotates together with the upper first rotating shaft through contact with the fourth transmission belt. When the first rotating shaft rotates, it drives the clamping conveyor belt and the second rotating shaft to rotate together. When the upper and lower clamping conveyor belts transport perilla, the perilla head first contacts the upper half of the guide plate, so that the head bends towards the extrusion plate. The bent perilla head enters the extrusion plate first. When passing through the extrusion plate, the leaves are subjected to a force opposite to the transport direction, thus separating from the root. The root continues to be transported with the clamping conveyor belt.

[0019] Furthermore, the extrusion plate is provided with a circular through hole, the radius of the inlet section of the circular through hole gradually decreases, and the extrusion plate is also provided with a material passage groove and a conveying groove, which are connected to each other.

[0020] When perilla is transported by the clamping conveyor belt, the perilla head is guided by the guide plate toward the circular through hole and enters from the larger inlet. As the radius of the circular through hole gradually decreases, the leaves are subjected to a force opposite to the transport direction, thus separating from the root and stem. The root and stem can continue to be transported through the feed trough, which is used to pass through the clamping conveyor belt.

[0021] Furthermore, the sorting mechanism includes a support plate, a vertical baffle, an inclined baffle, a vibration motor, a push rod, and a rangefinder. The support plate is fastened to the frame, the support plate is arranged at an angle, the support plate is equipped with a vibration motor, and the support plate is also equipped with a vertical baffle and an inclined baffle. There are two sets of vertical baffles and two sets of inclined baffles. The push rod is fastened to the frame, the push rod is placed below the support plate, and the push rod is equipped with a rangefinder.

[0022] The support plate is fixed to the frame and positioned at the outlet of the blade conveyor belt. Perilla leaves are conveyed to the support plate via the blade conveyor belt. The support plate is inclined so that the perilla leaves can slide down. Since the separated perilla leaves are arranged randomly and stacked, a vibrating motor on the support plate works to vibrate and separate the stacked perilla leaves as they slide down, flattening them on the plate surface. Because the vibration direction is directional, the perilla leaves will continue to move in the same direction under inertia until they are all pressed against the inclined baffle, thereby achieving width adjustment. Finally, each leaf falls sequentially onto the packaging mechanism below. After a certain number of perilla leaves have fallen, the distance measuring instrument measures their height. If it meets the standard of sixty to eighty leaves, the push rod pushes this batch of perilla leaves into the packaging mechanism.

[0023] Furthermore, the packaging mechanism includes a bundling machine and a blade collection frame. Both the bundling machine and the blade collection frame are securely connected to the base plate. The bundling machine is located on the side near the push rod, and the bundling machine and the blade collection frame are securely connected.

[0024] Both the bundling machine and the leaf collection frame are fixed on the base plate. After the perilla leaves are pushed into the bundling machine by the push rod, the bundling machine bundles and packages the perilla leaves. Then the push rod pushes the packaged perilla leaves into the leaf collection frame.

[0025] Compared with the prior art, the beneficial effects of the present invention are: 1. The grooves on the clamping conveyor belt are arranged at an inclination so that the perilla head faces the transportation direction. When transporting perilla, the perilla head first contacts the upper part of the guide plate and bends towards the extrusion plate. The bent perilla head first enters the extrusion plate. When passing through the extrusion plate, the leaves are subjected to a force opposite to the transportation direction, thereby separating from the root and stem. The root and stem continue to be transported with the clamping conveyor belt. The harvester realizes the separation of stems and leaves inside the machine and can collect perilla leaves and root and stem at the same time, saving resources. 2. The stacked perilla leaves are rearranged and bundled by a sorting mechanism, eliminating the need for manual operation and improving packaging efficiency. 3. Automatically detect the position of the lowest leaf on the perilla plant to dynamically adjust the height of the cutter and improve cutting efficiency. Attached Figure Description

[0031] The main body 1 is used to support the entire harvester. The harvesting mechanism 2, the separating mechanism 3, and the sorting mechanism 4 are fixed to the main body 1. The harvesting mechanism 2 is used to cut the perilla leaves and transport them to the sorting mechanism 4. The separating mechanism 3 is used to separate the perilla roots and leaves and to recycle the roots. The sorting mechanism 4 is used to sort and arrange the randomly placed leaves. The packing mechanism 5 is used to bundle and pack the sorted perilla leaves.

[0032] like Figure 1As shown, the machine body 1 includes a frame 11, a base plate 12 and wheels 13. The frame 11 and the base plate 12 are fastened together, and the frame 11 and the wheels 13 are rotatably connected. The frame 11 is fastened together with the harvesting mechanism 2, the separating mechanism 3 and the sorting mechanism 4 respectively. The base plate 12 is provided with a packing mechanism 5.

[0033] The frame 11 is used to fix the harvesting mechanism 2, the separating mechanism 3 and the sorting mechanism 4. The wheels 13 are used to control the forward, backward and turning of the entire harvester. The base plate 12 is fixed on the frame 11 and is used to support the packing mechanism 5.

[0034] like Figure 2 As shown, the harvesting mechanism 2 includes a cutting assembly 21, a main conveying assembly 22, and a detector 23. The cutting assembly 21 is fastened to the frame 11, the main conveying assembly 22 is rotatably connected to the frame 11, and the detector 23 is provided in several groups, with the several groups of detectors 23 being fastened to the frame 11.

[0035] The cutting component 21 is placed at the front end of the frame 11. The cutting component 21 is used to cut off a part of the rootstock with leaves. The cut perilla leaves are separated by the separation mechanism 3. The separated perilla leaves are transported to the sorting mechanism 4 by the main conveying component 22. The detector 23 is used to detect the position of the lowest leaf on the rootstock, thereby adjusting the cutting height and improving the cutting efficiency.

[0036] like Figures 2-3 As shown, the cutting assembly 21 includes a cutter 211, a cutting motor 212, a first transmission roller 213, a second transmission roller 214, a telescopic rod 215, a first transmission belt 216, a second transmission belt 217, a first support frame 218, and a second support frame 219. The cutting motor 212 is fastened to the frame 11, and the output end of the cutting motor 212 is fastened to the first transmission roller 213. The first support frame 218 is fastened to the frame 11, and the first support frame 218 is rotatably connected to the first transmission roller 213. The first transmission roller 213 and the first transmission belt 216 are also connected. Frictional contact occurs between the first transmission belt 216 and the second transmission roller 214, which are rotatably connected to the first support frame 218. The second transmission roller 214 and the second transmission belt 217 are in frictional contact, as are the second transmission belt 217 and the telescopic rod 215. Several sets of telescopic rods 215 and cutters 211 are provided, with the upper end of the telescopic rod 215 and the cutter 211 fastened together. Several sets of second support frames 219 are provided, which are fastened together to the machine frame 11. The second support frames 219 and the telescopic rod 215 are rotatably connected.

[0037] The cutter 211 is used to cut perilla leaves. The cutting motor 212 is mounted on the frame 11 and is a switch used to control the rotation of the cutter 211. The output torque of the cutting motor 212 drives the first transmission roller 213 to rotate. The first transmission roller 213 drives the second transmission roller 214 to rotate through contact with the first transmission belt 216 and the first transmission belt 216 and the second transmission roller 214. The second transmission roller 214 drives the telescopic rod 215 through contact with the second transmission belt 217 and the second transmission belt 217 and the telescopic rod 215. The telescopic rod 215 rotates, and the upper end of the telescopic rod 215 is fixed to the cutter 211. Therefore, the telescopic rod 215 drives the cutter 211 to rotate, thereby cutting the perilla. The first support frame 218 is fixed to the frame 11. The first support frame 218 is used to support the first transmission roller 213 and the second transmission roller 214. The telescopic rod 215 and the cutter 211 are respectively provided with several sets, which can cut multiple rows of perilla and improve cutting efficiency. The second support frame 219 is fixed to the frame 11. The second support frame 219 is used to support the telescopic rod 215.

[0038] like Figures 2-3 As shown, the main conveying assembly 22 includes a blade conveyor belt 221, a conveyor motor 222, a main conveyor roller 223, a third transmission belt 224, and a third transmission roller 225. The conveyor motor 222 is fastened to the frame 11. The output end of the conveyor motor 222 is fastened to the third transmission roller 225. The third transmission roller 225 and the third transmission belt 224 are in frictional contact. There are two sets of main conveyor rollers 223. One set of main conveyor rollers 223 is in frictional contact with the third transmission belt 224, and the two sets of main conveyor rollers 223 are in frictional contact with the blade conveyor belt 221. The two sets of main conveyor rollers 223 are rotatably connected to the frame 11.

[0039] The conveyor motor 222 is fixed to the frame 11. The output torque of the conveyor motor 222 drives the third transmission roller 225 to rotate. The third transmission roller 225 drives the main transmission roller 223 to rotate through contact with the third transmission belt 224 and the contact between the third transmission belt 224 and the main conveyor roller 223. The frame 11 supports the two sets of main conveyor rollers 223. When the two sets of main conveyor rollers 223 rotate, they drive the blade conveyor belt 221 to rotate. The perilla leaves are conveyed through the blade conveyor belt 221 and enter the sorting mechanism 4 when they reach the end.

[0040] like Figures 4-5As shown, the separation mechanism 3 includes a secondary conveying assembly 31, a pressing plate 32, a guide plate 33, and a root and stem collection frame 34. The secondary conveying assembly 31 is provided on one side of several sets of cutters 211, and the guide plate 33 is provided on the other side of several sets of cutters 211. The secondary conveying assembly 31 is fastened to the frame 11, the pressing plate 32 is fastened to the frame 11, the secondary conveying assembly 31 passes through the pressing plate 32, the guide plate 33 is arranged in an arc shape, the guide plate 33 is fastened to the frame 11, and the root and stem collection frame 34 is placed at the outlet end of the secondary conveying assembly 31 and is fastened to the frame 11.

[0041] The secondary conveyor assembly 31 is fixed to the frame 11. The perilla leaves cut by the cutter 211 enter the secondary conveyor assembly 31, which holds the perilla roots and stems for transport. When the perilla leaves are transported, the front end contacts the guide plate 33, which is arranged in an arc. When the perilla leaves pass through the guide plate 33, the front end bends in the transport direction, so that the perilla leaves face the extrusion plate 32. The bent front end of the perilla leaves enters the extrusion plate 32. When passing through the extrusion plate 32, since the perilla leaves face the same direction as the transport direction, they are squeezed by the extrusion plate 32 and the leaves are subjected to a force opposite to the transport direction, thus separating from the roots and stems. The leaves fall onto the leaf conveyor belt 221 for transport, while the roots and stems continue to be transported with the secondary conveyor assembly 31. After reaching the end, they fall into the root and stem collection box 34.

[0042] like Figure 4 As shown, the auxiliary conveying assembly 31 includes a clamping conveyor belt 311, a first rotating shaft 312, a clamping motor 313, a fourth transmission belt 314, a third support frame 315, a fourth support frame 316, and a second rotating shaft 317. Two sets of clamping conveyor belts 311 are provided, with grooves 3111 on the outer ring of each set. The grooves 3111 are inclinedly arranged. The third support frame 315 and the fourth support frame 316 are respectively fastened to the frame 11. The third support frame 315 is fastened to the guide plate 33, and the fourth support frame 316 is fastened to the clamping motor 313. The first rotating shaft 312 is... There are two sets: two sets of second rotating shafts 317 and two sets of fourth transmission belts 314. One set of fourth transmission belts 314 is in frictional contact with two sets of first rotating shafts 312, and the other set of fourth transmission belts 314 is in frictional contact with two sets of second rotating shafts 317. The two sets of first rotating shafts 312 are rotatably connected to the fourth support frame 316, and the two sets of second rotating shafts 317 are rotatably connected to the third support frame 315. The output end of the clamping motor 313 is fastened to one set of first rotating shafts 312, and one set of clamping conveyor belts 311 are in frictional contact with one set of first rotating shafts 312 and one set of second rotating shafts 317 respectively.

[0043] Because the cutter 211 rotates counterclockwise, the cut perilla root faces the clamping conveyor belt 311. The groove 3111 above the clamping conveyor belt 311 is arranged at an angle, so that the perilla head faces the transport direction. The fourth support frame 316 is fixed to the frame 11, and the clamping motor 313 is fixed to the fourth support frame 316. The clamping motor 313 outputs torque to drive the lower first rotating shaft 312 to rotate. The lower first rotating shaft 312, through contact with the fourth transmission belt 314, causes the upper first rotating shaft 312 to rotate together. When rotating, the clamping conveyor belt 311 and the second rotating shaft 317 come into contact with each other, causing the clamping conveyor belt 311 and the second rotating shaft 317 to rotate together. When the upper and lower clamping conveyor belts 311 transport perilla, the perilla head first contacts the upper half of the guide plate 33, so that the head bends towards the extrusion plate 32. After bending, the perilla head first enters the extrusion plate 32. When passing through the extrusion plate 32, the leaves are subjected to a force opposite to the transport direction, thus separating from the root and stem. The root and stem continue to be transported with the clamping conveyor belt 311.

[0044] like Figure 5 As shown, the extrusion plate 32 is provided with a circular through hole 321, the radius of the inlet section of the circular through hole 321 gradually decreases, and the extrusion plate 32 is also provided with a material passage 322 and a conveying groove 323, which are connected to each other.

[0045] When the perilla is transported by the clamping conveyor belt 311, the perilla head is guided by the guide plate 33 toward the circular through hole 321 and enters from the larger entrance. As the radius of the circular through hole 321 gradually decreases, the leaves are subjected to a force opposite to the transport direction, thus separating from the root and stem. The root and stem can continue to be transported through the feed trough 322. The conveying trough 323 is used to pass through the clamping conveyor belt 311.

[0046] like Figure 6 As shown, the sorting mechanism 4 includes a support plate 41, a vertical baffle 42, an inclined baffle 43, a vibration motor 44, a push rod 45, and a rangefinder 46. The support plate 41 is fastened to the frame 11. The support plate 41 is arranged at an angle. The vibration motor 44 is provided on the support plate 41. The support plate 41 is also provided with a vertical baffle 42 and an inclined baffle 43. There are two sets of vertical baffles 42 and inclined baffles 43 respectively. The push rod 45 is fastened to the frame 11. The push rod 45 is placed below the support plate 41. The rangefinder 46 is provided on the push rod 45.

[0047] The support plate 41 is fixed on the frame 11 and placed at the outlet end of the blade conveyor belt 221. Perilla leaves are conveyed to the support plate 41 through the blade conveyor belt 221. The support plate 41 is inclined downward so that the perilla leaves can slide down. Since the separated perilla leaves are arranged randomly and stacked, the vibration motor 44 on the support plate 41 works to make the stacked perilla leaves separate and flatten on the plate while sliding down. Since the vibration direction is directional, the perilla leaves will continue to move in the same direction under the action of inertia until they are all close to the inclined baffle 43, thereby realizing the adjustment of the width direction. Finally, each leaf falls into the packaging mechanism 5 below in sequence. After a certain number of perilla leaves have fallen, the rangefinder 46 measures their height. If it meets the standard of sixty to eighty pieces, the push rod 45 pushes this batch of perilla leaves into the packaging mechanism 5.

[0048] like Figure 7 As shown, the packaging mechanism 5 includes a bundling machine 51 and a leaf collection frame 52. Both the bundling machine 51 and the leaf collection frame 52 are fastened to the base plate 12. The bundling machine 51 is located on the side close to the push rod 45, and the bundling machine 51 and the leaf collection frame 52 are fastened together.

[0049] Both the bundling machine 51 and the leaf collection frame 52 are fixed on the base plate 12. After the perilla leaves are pushed into the bundling machine 51 by the push rod 45, the bundling machine 51 bundles and packages the perilla leaves. Then the push rod 45 pushes the packaged perilla leaves into the leaf collection frame 52.

[0050] Working principle of the invention: The cutter 211 is used to cut the perilla leaves. After cutting, the root of the perilla leaves faces the clamping conveyor belt 311. The groove 3111 above the clamping conveyor belt 311 is arranged at an angle so that the head of the perilla leaves faces the transport direction. When the clamping conveyor belt 311 transports the perilla leaves, the head of the perilla leaves contacts the guide plate 33 and bends towards the extrusion plate 32. When passing through the extrusion plate 32, the leaves are subjected to a force opposite to the transport direction, thus separating from the root and stem. The root and stem continue to be transported with the clamping conveyor belt 311, and the perilla leaves fall onto the leaf conveyor. Belt 221: Perilla leaves are conveyed to support plate 41 via blade conveyor belt 221. Vibration causes the perilla leaves to separate and spread flat on the plate surface. Since the vibration direction is directional, the perilla leaves will all stick to the inclined baffle 43, thereby achieving width adjustment. Finally, rangefinder 46 measures the number of perilla leaves that have fallen. Push rod 45 pushes this batch of perilla leaves into bundling machine 51. Bundling machine 51 bundles and packages the perilla leaves. Then, push rod 45 pushes the packaged perilla leaves into blade collection frame 52.
