Description

Technical Field

[0001] This invention relates to the field of harvester technology, specifically to a silage harvesting system and a silage harvester. Background Technology

[0002] Existing silage material handling systems are simple integrations of the working parts of a small backpack silage machine. The main working parts are all integrated on the cutting table, resulting in a simple layout and poor material handling capacity. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a silage harvesting system and a silage harvester to address the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A silage harvesting system includes a frame and a silage cutting platform, a conveying module, a feeding module, a chopping module, a throwing module, and a throwing cylinder installed on the frame. The conveying module is located behind the silage cutting platform and conveys the harvested crop backward. The feeding module is located behind the conveying module and feeds the crop backward. The chopping module is installed behind the feeding module and chops the fed crop and conveys it backward to the throwing module. The throwing cylinder is installed behind the throwing module. The throwing module is located behind the chopping module and throws the chopped material through the throwing cylinder.

[0005] The beneficial effects of the present invention are as follows: The silage harvesting system of the present invention feeds the material from the cutting and feeding disc, and then the material is conveyed through the conveying module, which can improve the feeding amount and conveying efficiency. Moreover, the feeding and chopping module at the rear can compact and cut the fed stalks. The chopped material is thrown backward through the throwing module and the throwing cylinder. The throwing cylinder is located in the middle and rear part of the vehicle and adopts a parabolic shape, which can throw a long distance and realize the function of following the vehicle to catch hay.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, it also includes a forage harvester transmission system, which includes a power mechanism, a header transmission assembly, a lower header disc drive gearbox, and a lower header conveyor wheel drive gearbox. The power mechanism is driven by the chopping module, the header transmission assembly is driven by the feeding module, and the header transmission assembly is also driven by the lower header disc drive gearbox and the lower header conveyor wheel drive gearbox through the feeding module. The lower header disc drive gearbox is driven by the header disc, and the lower header conveyor wheel drive gearbox is driven by the conveying module.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the forage machine transmission system transmits power to the chopping module, the lower cutting table disc drive gearbox and the lower cutting table conveyor wheel drive gearbox through the power mechanism, which can provide power to the chopping module, the lower forage cutting table disc and the lower forage conveyor wheel respectively.

[0009] Furthermore, the feeding module includes a front upper roller, a front lower roller, a rear upper roller, and a rear lower roller; the header transmission assembly includes a first header shaft and a second header shaft, one end of the chopping module is drivenly connected to the first header shaft, the first power output end of the first header shaft is drivenly connected to the power input end of the rear upper roller, and the power output end of the rear upper roller is drivenly connected to the power input end of the front upper roller; the second power output end of the first header shaft is used to connect to the ear-picking header on the upper layer of the silage header, and the second power output end of the first header shaft also transmits power to the second header shaft through a gear set, the first power output end of the second header shaft is connected to the power input end of the front lower roller, the power output end of the front lower roller is drivenly connected to the lower header disc drive gearbox, and the second power output end of the second header shaft is drivenly connected to the lower header disc drive gearbox and the lower header conveyor wheel drive gearbox respectively.

[0010] The beneficial effects of adopting the above-mentioned further scheme are as follows: the power is transmitted to the two header shafts through the power mechanism. The power of the first header shaft is divided into two paths. One path is output to the upper roller of the feeding system, and then transmitted to the upper front roller through the right side of the upper rear roller. The other path is output to the upper ear-picking header and the second header shaft. Then the second header shaft further divides the power into two paths. One path is output to the lower front roller of the feeding system, and then transmitted to the lower header disc drive gearbox on the right side through the right side of the lower front roller. The other path is output to the lower header conveyor wheel drive gearbox and the lower header disc drive gearbox. Since the disc drive power is much greater than the conveyor wheel drive power, the lower header disc drive gearbox is input to the left and right through the second header shaft by splitting the power input, ensuring the operability of the transmission.

[0011] Furthermore, the first power output end of the second cutting table shaft is connected to the front lower roller sprocket of the front lower roller and drives the front lower roller to rotate through the front lower roller sprocket. The front lower roller sprocket is connected to the rear lower roller sprocket of the rear lower roller power input end. The power output end of the front lower roller is connected to the lower cutting table disc drive gearbox through the input sprocket assembly on the right side of the lower cutting table. The second power output end of the second cutting table shaft is connected to the lower cutting table conveyor wheel drive gearbox through the input sprocket of the lower cutting table conveyor wheel drive box.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it facilitates power transmission by transmitting power through sprockets and chains.

[0013] Furthermore, the power output end of the shredder shaft is provided with a double-row sprocket on the left side of the shredder shaft. The double-row sprocket on the left side of the shredder transmits power to the upper rear roller, the upper ear-picking header and the lower header disc drive gearbox respectively through the chain and the first double-row transmission sprocket on the first header shaft.

[0014] The first cutting table shaft is connected to the feed upper roller transition sprocket via a first universal joint, and the feed upper roller transition sprocket is connected to the rear upper roller sprocket via a chain.

[0015] The beneficial effect of adopting the above-mentioned further solution is that bidirectional power transmission can be achieved through the double-row sprockets.

[0016] Furthermore, the two ends of the front upper roller and the two ends of the rear upper roller are movably connected to the frame, and the two ends of the front upper roller and the corresponding two ends of the rear upper roller are connected by floating connecting plates, which are connected to the frame by floating springs.

[0017] The frame has two oppositely arranged first floating holes and two oppositely arranged second floating holes. The first floating holes and the second floating holes are arranged in parallel. The two ends of the front upper roller are respectively movably connected to the two first floating holes, and the two ends of the rear upper roller are respectively movably connected to the two second floating holes. The two ends of the front upper roller and the corresponding two ends of the rear upper roller are respectively connected by floating connecting plates.

[0018] The beneficial effects of adopting the above-mentioned further scheme are as follows: The power source of the front upper roller is transmitted from the left side of the rear upper roller to the right side and then to the front upper roller. Since the front and rear upper rollers need to float up and down according to the feed amount, this power source of the front upper roller ensures the stability of the joint up and down floating of the front and rear upper rollers, and ensures the stable state of the front and rear upper rollers in compacting and clamping the fed material. By setting floating springs and floating connecting plates, it can be ensured that the front and rear upper rollers of the feeding system float up and down according to the different feed amounts of the material. The floating connecting plate connects the front and rear upper rollers, so that the center distance between the front and rear upper rollers remains unchanged during the floating process, ensuring that the two upper rollers float synchronously. During the floating process, the power is transmitted to the front upper roller through the rear upper roller, ensuring good power transmission during the floating process and always maintaining the compaction effect on the fed material. By setting floating holes, floating space is provided for the front and rear upper rollers.

[0019] Furthermore, the conveying module includes two conveying wheels arranged side by side and a conveying wheel scraper box, with a conveying gap reserved between the two conveying wheels for conveying materials; the conveying wheel scraper box has multiple scraper gaps for the conveying wheel teeth to be inserted one-to-one, the multiple scraper gaps are distributed along the axial direction of the conveying wheel, and the extension direction of each scraper gap is perpendicular to the axial direction of the conveying wheel; the conveying wheel includes multiple layers of conveying wheel teeth arranged at intervals, and the multiple layers of conveying wheel teeth are inserted one-to-one into the multiple scraper gaps of the conveying wheel scraper box.

[0020] The beneficial effects of adopting the above-mentioned further scheme are: by using the scraper comb teeth of the conveyor wheel scraper and the conveyor wheel teeth in close cooperation, the scraper that cooperates with the multi-layer teeth of the conveyor wheel needs to be arranged in a layered and interlocked manner with the conveyor teeth in the direction of the axis of the cooperating conveyor wheel, so that each layer of teeth of the conveyor wheel can smoothly rotate through the design gaps of the scraper, which is conducive to the stable and continuous conveying of materials by the conveyor wheel teeth.

[0021] Furthermore, the silage cutting platform includes multiple cutting discs, and a guide rod is provided on the frame of the silage cutting platform. The guide rod is located above the multiple cutting discs. The guide rod includes a connecting rod and a U-shaped rod. One end of the connecting rod is hinged to the frame, and the other end of the connecting rod is fixed to the bottom of the U-shaped rod. The open end of the U-shaped rod is arranged facing forward and covers the front feeding width of the multiple cutting discs.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the U-shaped rod and the connecting rod can be used together to hold the feeding stem, making it easier to feed the stem.

[0023] A silage harvester includes the aforementioned silage harvesting system and a harvesting platform. The bottom of the harvesting platform is connected to the frame of the silage harvesting platform by U-bolts. The top rear side of the harvesting platform is connected to the frame of the silage harvesting platform by a first adjusting rod. The bottom middle position of the harvesting platform body is connected to the frame of the silage harvesting platform by a second adjusting rod.

[0024] The front end of the ear-picking cutting platform is provided with multiple mounting plates, and each mounting plate is provided with at least one U-bolt. The two ends of the U-bolt are respectively locked and fixed to the mounting plate by nuts.

[0025] The beneficial effects of this invention are as follows: The silage harvesting system of this invention feeds the material from the cutting and feeding disc, and then transports the material through vertical conveyor wheels, which can improve the feeding amount and conveying efficiency. Furthermore, the rear feeding and chopping module can compact and cut the fed stalks. The chopped material is then thrown backward through the throwing module and throwing cylinder. The throwing cylinder is located in the middle and rear of the vehicle and has a parabolic shape, resulting in a long throwing distance and enabling it to catch the silage from the vehicle. By setting multiple mounting plates at the bottom front end of the ear-picking cutter and at least one U-bolt on each mounting plate, the bottom front end of the ear-picking cutter can be mounted to the frame of the silage cutter using the U-bolts on the mounting plates. This ensures that the center of the entire ear-picking cutter falls on the receiving position of the lower silage cutter. Moreover, by setting a first adjusting rod and a second adjusting rod, and by loosening the U-bolts to adjust the center distance between the first and second adjusting rods, the front and rear positions of the ear-picking cutter body can be adjusted.

[0026] Furthermore, it also includes a support leg, which includes a vertical support rod, a bottom support beam, and a top support rod. The bottom end of the vertical support rod is vertically connected to the bottom support beam, and the top end of the vertical support rod is vertically connected to the top support rod. The top support rod is arranged at an angle to the bottom support beam. The top support rod is detachably connected to the ear-picking cutting platform.

[0027] The beneficial effects of adopting the above-mentioned further solution are as follows: By using detachable support legs on the ear-picking cutter platform to temporarily support the upper ear-picking cutter platform, it is convenient for the operator in the cab to ensure that the upper ear-picking cutter platform with the support leg mechanism can touch the ground first when lowering the cutter platform from the highest point to the lowest point. Then, the connection structure between the ear-picking cutter platform and the silage cutter platform can be disassembled, and the lower silage cutter platform can be lowered to separate the upper and lower cutter platforms while maintaining a certain safe distance. Then, the operator can reverse the vehicle to complete the disassembly of the entire upper ear-picking cutter platform. If the ear-picking cutter platform is to be installed on the silage cutter platform, the above steps can be reversed to complete the assembly of the ear-picking cutter platform.

[0062] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0063] Example 1

[0064] like Figures 1 to 6 As shown, a silage harvesting system according to this embodiment includes a frame 500 and a silage cutter head 810, a conveying module, a feeding module 312, a chopping module 202, a throwing module 811, and a throwing cylinder 812 mounted on the frame 500. The conveying module is located behind the silage cutter head 810 and conveys the harvested crop backward. The feeding module 312 is located behind the conveying module and feeds the crop backward. The chopping module 202 is located behind the feeding module 312 and chops the fed crop before conveying it backward to the throwing module. The throwing cylinder 812 is mounted behind the throwing module 811, which is located behind the chopping module 202 and throws the chopped material through the throwing cylinder 812. The material can be thrown into a hay collection box 813 at the rear of the silage harvesting system or into a hay receiving cart following behind the silage harvesting system.

[0065] like Figures 1-3As shown, the silage harvesting system in this embodiment also includes a silage harvester transmission system. The silage harvester transmission system includes a power mechanism 100, a header transmission assembly, a lower header disc drive gearbox 103, and a lower header conveyor wheel drive gearbox 102. The power mechanism 100 is driven by the chopping module 202. The header transmission assembly is driven by the feeding module 312. The header transmission assembly is also driven by the feeding module 312 to the lower header disc drive gearbox 103 and the lower header conveyor wheel drive gearbox 102, respectively. The lower header disc drive gearbox 103 is driven by the header disc 818, and the lower header conveyor wheel drive gearbox 102 is driven by the conveying module. The silage harvester transmission system transmits power to the chopping module, the lower header disc drive gearbox, and the lower header conveyor wheel drive gearbox through the power mechanism, providing power to the chopping module, the lower silage header disc, and the lower silage conveyor wheel, respectively.

[0066] like Figures 1-3As shown, the feeding module 312 includes a front upper roller 301, a front lower roller, a rear upper roller 302, and a rear lower roller; the cutting table transmission assembly includes a first cutting table shaft 300 and a second cutting table shaft 400. One end of the chopping module 202 is connected to the first cutting table shaft 300, the first power output end of the first cutting table shaft 300 is connected to the power input end of the rear upper roller, and the power output end of the rear upper roller 302 is connected to the power input end of the front upper roller 301; the second power output end of the first cutting table shaft 300 is used to connect with the green... The upper layer of the harvesting platform 810 is connected to the ear-picking platform 800. The second power output end of the first platform shaft 300 also transmits power to the second platform shaft 400 through a gear set. The first power output end of the second platform shaft 400 is connected to the power input end of the front lower roller. The power output end of the front lower roller is connected to the drive gear box 103 of the lower platform disc. The second power output end of the second platform shaft 400 is connected to the drive gear box 103 of the lower platform disc and the drive gear box 102 of the lower platform conveyor wheel, respectively. Power is transmitted to two header shafts via a power mechanism. The power of the first header shaft is split into two paths. One path outputs to the upper roller 302 of the feeding system, and then transmits power to the upper front roller 301 via the right side of the upper rear roller 302. The other path outputs to the upper ear-picking header 800 and the second header shaft 400. The second header shaft 400 then splits the power into two paths. One path outputs to the lower front roller of the feeding system, and then transmits power to the lower header disc drive gearbox 103 on the right side via the right side of the lower front roller. The power is then integrated from the right side of the entire transmission system via the lower front roller. The other path outputs to the lower header conveyor wheel drive gearbox 102 and the lower header disc drive gearbox 103, and then integrates power from the left side of the entire system via the second power output end of the second header shaft 400. Since the disc drive power is much greater than the conveyor wheel drive power, the lower header disc drive gearbox 103 is split into left and right inputs via the second header shaft 400 to ensure the operability of the transmission.

[0067] like Figures 1-3As shown, in this embodiment, the first power output end of the second cutter shaft 400 is connected to the front lower roller sprocket 304 of the front lower roller and drives the front lower roller to rotate by driving the front lower roller sprocket 304. The front lower roller sprocket 304 is connected to the rear lower roller sprocket 305 of the rear lower roller power input end. Specifically, the second cutter shaft 400 can be connected to the front lower roller sprocket 304 through the second universal joint 105. The power output end of the front lower roller is connected to the right input sprocket 309 of the first lower cutter. The right input sprocket 309 of the first lower cutter is connected to the right input sprocket 310 of the second lower cutter through a chain. The right input sprocket 310 of the second lower cutter is connected to the lower cutter disc drive gearbox 103 through a chain. Power is transmitted via sprockets and chains for convenient power transfer; the power is transmitted to the right side of the entire front lower roller via the second cutting table shaft 400, and then from the right side to the lower cutting table disc drive gearbox 103, thus realizing the right-side convergence of power into the lower cutting table disc drive gearbox 103.

[0068] like Figure 1 As shown, the power output end of the chopping blade shaft 200 in this embodiment is equipped with a double-row sprocket 201 on the left side of the chopping blade shaft. The double-row sprocket 201 transmits power to the upper rear roller 302, the upper ear-picking header 800, and the lower header disc drive gearbox 103 respectively via a chain and a double-row transmission sprocket 311 on the first header shaft 300. The first header shaft is connected to the feed upper roller transition sprocket via a first universal joint, and the feed upper roller transition sprocket is connected to the upper rear roller sprocket of the upper rear roller via a chain. The double-row sprockets enable bidirectional power transmission.

[0069] like Figure 1 As shown, in this embodiment, the first cutting table shaft 300 is connected to the feed upper roller transition sprocket 303 via a first universal joint 104, and the feed upper roller transition sprocket 303 is connected to the rear upper roller sprocket 306 of the rear upper roller 302 via a chain. Specifically, as... Figure 1 As shown, the power input end of the rear upper roller 302 is connected to the rear upper roller sprocket 306, and the power output end of the rear upper roller 302 is connected to the rear upper roller output sprocket 308. The rear upper roller output sprocket 308 is connected to the front upper roller input sprocket 307 via a chain. The front upper roller input sprocket 307 is connected to the front upper roller 301 and drives the front upper roller 301 to rotate.

[0070] like Figures 1-3As shown, in this embodiment, the two ends of the front upper roller 301 and the two ends of the rear upper roller 302 are movably connected to the frame 500. The two ends of the front upper roller 301 and the corresponding two ends of the rear upper roller 302 are connected by floating connecting plates 503, which are connected to the frame 500 by floating springs 504. The power source of the front upper roller 301 is transmitted from the left side of the rear upper roller 302 to the right side and then to the front upper roller 301. Since the front upper roller 301 and the rear upper roller 302 need to float up and down according to the feed amount, this power source of the front upper roller 301 ensures the stability of the front upper roller 301 and the rear upper roller 302 floating up and down together, and ensures the stable state of the front upper roller 301 and the rear upper roller 302 in compacting and clamping the fed material. The upper end of the floating spring 504 is connected to the floating connecting plate 503, and the lower end of the floating spring 504 is connected to the corresponding frame 500, enabling the floating connecting plate 503 and the front upper roller 301 and rear upper roller 302 connected to both ends of the floating connecting plate 503 to float simultaneously. By setting the floating spring 504 and the floating connecting plate 503, it can be ensured that the front upper roller 301 and rear upper roller 302 of the feeding system float up and down according to the different material feeding amounts. The floating connecting plate 503 connects the front upper roller 301 and rear upper roller 302, so that the center distance between the front upper roller 301 and rear upper roller 302 remains unchanged during the floating process, ensuring that the two upper rollers float synchronously. During the floating process, the power is transmitted to the front upper roller 301 through the rear upper roller 302, ensuring good power transmission during the floating process and always maintaining the compaction effect on the fed material.

[0071] like Figure 2 and Figure 3 As shown, the frame 500 in this embodiment has two oppositely arranged first floating holes 501 and two oppositely arranged second floating holes 502. The first floating holes 501 and the second floating holes 502 are arranged parallel to each other. The two ends of the front upper roller 301 are movably connected to the two first floating holes 501, and the two ends of the rear upper roller 302 are movably connected to the two second floating holes 502. The two ends of the front upper roller 301 and the corresponding two ends of the rear upper roller 302 are connected by floating connecting plates 503. By setting the floating holes, floating space is provided for the front upper roller and the rear upper roller.

[0072] like Figure 1As shown, in this embodiment, the second power output end of the second cutter shaft 400 is connected to the lower cutter conveyor wheel drive gearbox 102 via the input sprocket 401 of the lower cutter conveyor wheel drive box. Specifically, the second power output end of the second cutter shaft 400 is connected to the first lower cutter disc input sprocket 403, which is connected to the second lower cutter disc input sprocket 404 via a chain. The second lower cutter disc input sprocket 404 is connected to the lower cutter disc drive gearbox 103 via a gearbox. The second power output end of the second cutter shaft 400 is also connected to the conveyor wheel power transmission sprocket 406, which is connected to the lower cutter conveyor wheel drive gearbox 102 via a chain. The conveyor wheel power transmission sprocket 406 and the first lower cutter disc input sprocket 403 are coaxially mounted on the second cutter shaft 400, as shown in the diagram. Figure 1 As shown, the power transmission sprocket 406 of the conveyor wheel can be installed on one side of the input sprocket 403 of the first lower cutting table disc.

[0073] like Figure 1 As shown, the power mechanism 100 in this embodiment includes an engine, the power output end of which is connected to the power input end of the intermediate shaft 101, and the power output end of the intermediate shaft 101 is connected to the power input end of the shredder shaft 200 via a belt.

[0074] like Figure 1 As shown, in this embodiment, two shredding rollers are mounted side-by-side on the shredding shaft 200, with the shredding blades on the two rollers staggered and angled. The shredding roller structure has a large shredding area and strong shredding capacity, ensuring control over shredding quality and cutting length. The shredding shaft and its shredding rollers are located behind the feed roller assembly, which includes a front upper roller 301, a rear upper roller 302, a front lower roller, and a rear lower roller. The front upper roller 301 and the rear upper roller 302 are respectively located above the front lower roller and the rear lower roller.

[0075] The transmission process of the silage harvester transmission system in this embodiment is as follows: Figure 1 As shown, according to Figure 1The arrows indicate the direction. The power mechanism 100 (e.g., an engine) transmits power to the chopping blade shaft 200 via the intermediate shaft 101. The chopping blade shaft 200 transmits power to the double-row drive sprocket 311 located on the first header shaft 300 via the double-row sprocket 201 on the left side of the chopping blade shaft. The double-row drive sprocket 311 transmits power to the left and right sides of the first header shaft 300 respectively. From the left side of the first header shaft 300, power is transmitted to the upper ear-picking header input sprocket 402, and then to the upper ear-picking header 800. The first header shaft 300 on the left side of the double-row drive sprocket 311 is also equipped with a drive gear. A gear set 405 is formed by the drive gear and other gears meshing with the drive gear. The power is transmitted rearward to the second cutting table shaft 400; then, the power is transmitted from the right side of the first cutting table shaft 300 to the feed upper roller transition sprocket 303 through the first universal joint 104. The feed upper roller transition sprocket 303 transmits the power rearward to the rear upper roller sprocket 306. The rear upper roller sprocket 306 drives the rear upper roller 302 to move. At the same time, the power is transmitted from the right side of the rear upper roller 302 to the front upper roller sprocket 304. The front upper roller sprocket 304 then drives the front upper roller 301 to move. It is equivalent to the power of the front upper roller being transmitted from back to front in one revolution. The power of the front upper roller 301 and the rear upper roller 302 is driven by the power transmitted from the first cutting table shaft 300, which is beneficial for the simultaneous floating of the subsequent front and rear upper rollers. The second cutting table shaft 400 receives power from the first cutting table shaft 300 and transmits the power to the left and right sides of the second cutting table shaft 400 respectively. The second cutting table shaft 400 transmits power to the left to the first lower cutting table disc input sprocket 403 and the conveyor wheel power transmission sprocket 406. The first lower cutting table disc input sprocket 403 transmits power to the second lower cutting table disc input sprocket 404, and then transmits power from the left to the lower cutting table disc drive gearbox 103. The conveyor wheel power transmission sprocket 406 transmits power to the lower cutting table conveyor wheel drive box input sprocket 401. The lower cutting table conveyor wheel drive box input sprocket 401 drives the conveyor wheel to rotate, and at the same time further transmits power to the lower cutting table disc drive gearbox 103 to meet the power requirements of the disc cutting table. The second cutter shaft 400 transmits power to the front lower roller sprocket 304 via the second universal joint 105 to the right. The front lower roller sprocket 304 drives the front lower roller 301 to move, and the front lower roller sprocket 304 directly drives the rear lower roller sprocket 305 to drive the rear lower roller 302 to move. The front lower roller sprocket 304 transmits power to the right input sprocket 309 of the first lower cutter via the right side of the front lower roller 301. The right input sprocket 309 of the first lower cutter then transmits power from the right side to the lower cutter disc drive gearbox 103 via the right input sprocket 310 of the second lower cutter. In this embodiment, the power transmission method transmits power to the lower cutter disc drive gearbox 103 from both the left and right sides, thus splitting the power source of the lower cutter disc drive gearbox 103 to the left and right sides. The transmission layout is reasonable, the structure is compact and reliable, and the operability and stability of the transmission are guaranteed.

[0076] In this embodiment, the silage harvester transmission system transmits power to two header shafts via a power mechanism 100. The power of the first header shaft 300 is split into two paths: one path outputs to the upper rear roller 302 of the feeding system, and then transmits power to the upper front roller 301 via the right side of the upper rear roller 302; the other path outputs to the upper ear-picking header 800 and the second header shaft 400. The second header shaft 400 then splits the power into two paths: one path outputs to the lower front roller of the feeding system, and then transmits power from the right side of the lower front roller to the lower header disc drive gearbox 103; the other path outputs to the lower header conveyor wheel drive gearbox 102 and the lower header disc drive gearbox 103. Since the disc drive power is much greater than the conveyor wheel drive power, the lower header disc drive gearbox 103 is split into left and right inputs via the second header shaft 400 to ensure the operability of the transmission.

[0077] like Figure 6 and Figure 18 As shown, the conveying module in this embodiment includes two conveying wheels 604 arranged side by side and a conveying wheel scraper box. A conveying gap for conveying materials is reserved between the two conveying wheels 604. The conveying wheel scraper box has multiple scraper gaps 711 for the conveying wheel teeth 605 to be inserted one-to-one. The multiple scraper gaps 711 are distributed along the axial direction of the conveying wheel, and the extension direction of each scraper gap 711 is perpendicular to the axial direction of the conveying wheel 604. The conveying wheel 604 includes multiple layers of conveying wheel teeth 605 arranged at intervals. The multiple layers of conveying wheel teeth 605 are inserted one-to-one into the multiple scraper gaps 711 of the conveying wheel scraper box. By using the scraper comb teeth and conveying wheel teeth of the conveying wheel scraper in close cooperation, the scraper that cooperates with the multiple layers of teeth of the conveying wheel needs to have a layered and interlocking structure in the direction of the axis of the cooperating conveying wheel, so that each layer of teeth of the conveying wheel can smoothly rotate through the design gaps of the scraper, which is conducive to the stable and continuous conveying of materials by the conveying wheel teeth.

[0078] like Figure 16As shown, the scraper box body of this embodiment includes a first connecting section 705 and a second connecting section 706 that are interconnected and arranged at an angle. The first connecting section 705 has multiple scraper gaps 711, and each scraper tooth 710 forming the scraper gap 711 has a first insertion hole 707. The second connecting section 706 has multiple second insertion holes 708, which are arranged along the axial direction of the conveyor wheel 604 and correspond one-to-one with the first insertion holes 707 on each scraper tooth 710. Reinforcing plates 709 are inserted into the corresponding first insertion holes 707 and second insertion holes 708. By providing insertion holes on the scraper teeth of the first connecting section and the second connecting section, insertion protrusions can be provided on the two edges of the reinforcing plates. These insertion protrusions are then inserted into the corresponding first and second insertion holes, thus strengthening the structure of the conveyor wheel scraper box.

[0079] like Figure 16 As shown, in one optional embodiment, the reinforcing plate 709 has a triangular structure. Using a triangular reinforcing plate achieves structural reinforcement while also saving space.

[0080] like Figure 16 and Figure 17 As shown, each layer of the conveyor wheel teeth 605 includes multiple tooth segments 608, of which at least one tooth segment 608 has a thick tooth block 609 on one side edge. By providing a thick tooth block 609 on one side edge of the tooth segment 608, the conveyor wheel 604 can comb through the gap area between the scraper box grooves during rotation, preventing the scraper gap 711 between the scraper comb teeth 710 from becoming blocked.

[0081] like Figure 16 and Figure 17 As shown, along the rotation direction of the conveyor wheel 604, a thick tooth block 609 is provided on one side edge of the toothed lobe 608 that first enters the scraper gap 711. The thick tooth block 609 extends along the length direction of the toothed lobe 608. The thick tooth block 609 is detachably connected to or welded to one side of the conveyor wheel's teeth 605. The thick tooth block 609 on the side where the toothed lobe 608 first enters the scraper gap 711 allows for initial scraping of the scraper gap 711, facilitating the smooth passage of subsequent toothed lobe 608. Extending the thick tooth block 609 along the length direction of the toothed lobe 608 ensures effective scraping of the entire scraper gap 711.

[0082] like Figure 21As shown, in this embodiment, the maximum axial distance C between the conveyor wheel teeth 605 and the corresponding scraper gap 711 sidewall is no greater than 5mm; the maximum axial distance D between the thick tooth portion of the conveyor wheel teeth 605 and the corresponding scraper gap 711 sidewall is no greater than 2mm. This gap is to ensure that grass does not get tangled. During the rotation process, the material is guided by the conveyor wheel scraper box to make the width of the material outlet of the cutting table consistent with the width of the feeding device, thereby smoothly feeding the material into the main unit.

[0083] like Figure 23 As shown, in this embodiment, the maximum radial distance F between the cylinder wall 607 of the conveying wheel 604 and the leading edge of the corresponding scraper comb 710 is no greater than 5mm. This ensures the smoothness of the scraper in guiding materials and avoids clogging.

[0084] like Figures 19-23 As shown, in this embodiment, the maximum gap E between the outermost edge of the rotating area of ​​the conveyor wheel teeth 605 and the bottom of the scraper gap 711 of the scraper comb teeth 710 is no greater than 10mm. To ensure good scraper performance, in addition to the gap control in the axial direction, in the radial direction, i.e., the gap area traversed by each layer of teeth, the maximum gap between the outermost edge of the rotating area of ​​the teeth and the bottom of the scraper gap 711 of the scraper comb teeth 710 does not exceed 10mm. This gap design is to ensure that no backflow occurs during the rotation of the teeth, prevent straw blockage, and ensure smooth material flow.

[0085] The scraper box of the conveyor wheel must be used in close cooperation with the conveyor wheel. The conveyor wheel has a multi-layer feeding tooth design, so the matching scraper needs to be arranged in a layered, interlocking manner with the feeding teeth along the axis of the matching conveyor wheel. This allows each layer of teeth of the conveyor wheel to rotate smoothly through the design gaps in the scraper, and ensures that the maximum gap between the teeth and the design gaps in the axial direction does not exceed 5mm. The maximum gap between the thick teeth 606 on each layer of teeth and the design gaps in the axial direction does not exceed 2mm. The maximum gap between the leading edge of the scraper and the wall of the conveyor wheel does not exceed 5mm. This gap is to ensure that grass does not get tangled. During the rotation, the material will be guided by the scraper teeth to make the width of the material outlet of the cutting table consistent with the width of the feeding device, thereby smoothly feeding the material into the main unit. To ensure optimal scraper performance, in addition to axial clearance control, the maximum gap between the outermost edge of the rotating area of ​​each tooth and the bottom of the scraper gap between the tooth and the comb tooth in the radial direction (i.e., the gap area traversed by each layer of teeth) should not exceed 10mm. This gap design prevents backflow during tooth rotation, thus avoiding straw blockage and ensuring smooth material flow. Since material conveying relies entirely on the teeth to guide the flow, it is crucial to minimize radial clearance to prevent obstruction. Appropriate gaps at suitable radial quadrant points, aligned with the channel, prevent irreversible phenomena such as backflow.

[0086] like Figure 19 As shown, the conveyor wheel assembly in this embodiment also includes a conveyor wheel transmission box 700, a safety clutch base 701, a safety clutch 702, and a gearbox 703. The gearbox 703 is externally connected to the safety clutch base 701 via an external spline on its output shaft. The safety clutch 702 engages with the safety clutch base 701 via a friction plate assembly. The safety clutch 702 is connected to the output shaft of the gearbox 703 via a central bolt 704, and the safety clutch 702 is fixed to the shaft head of the gearbox 703. The conveyor wheel 604 has a vertical, high-cylinder wheel structure with a mounting plate in the middle. The gearbox 703 is externally connected to the safety clutch base 701 via an external spline on the output shaft. Friction plates are mounted on the base. The mounting plate of the conveyor wheel 604 is then placed on top of the friction plates, and more friction plates are mounted on the upper surface of the mounting plate. Finally, the safety clutch 702 is mounted on top of the friction plates. The safety clutch 702 is connected to the output shaft of the gearbox 703 via a bolt 704 in the middle, and the safety clutch 702 is fixed to the shaft head of the gearbox 703. In this way, a safety clutch transition is added between the conveyor wheel 604 and the transmission system, which can ensure the safety of the transmission system and also fix the conveyor wheel well.

[0087] In this embodiment, the conveyor wheel assembly uses the scraper comb teeth and conveyor wheel teeth in close cooperation. The scraper that cooperates with the multi-layer teeth of the conveyor wheel needs to be arranged in a layered and interlocking manner with the conveyor teeth in the direction of the axis of the cooperating conveyor wheel. This allows each layer of teeth of the conveyor wheel to rotate smoothly through the design gaps of the scraper, which is conducive to the stable and continuous conveying of materials by the conveyor wheel teeth.

[0088] like Figure 6 As shown, the silage harvester 810 in this embodiment includes multiple harvester discs 818. A guide rod is provided on the frame 500 of the silage harvester 810, and the guide rod is located above the multiple harvester discs 818. The guide rod includes a connecting rod 817 and a U-shaped rod 816. One end of the connecting rod 817 is hinged to the frame 500, and the other end of the connecting rod 817 is fixed to the bottom of the U-shaped rod 816. The open end of the U-shaped rod 816 faces forward and covers the front feeding width of the multiple harvester discs 818. The U-shaped rod and the connecting rod work together to support the feeding stalks, facilitating stalk feeding.

[0089] The silage harvesting system of this embodiment feeds the material from the cutting and feeding disc, and then the material is transported by the vertical conveyor wheel, which can improve the feeding amount and conveying efficiency. Moreover, the feeding and chopping module at the rear can compact and cut the fed stalks. The chopped material is thrown backward through the throwing module and the throwing cylinder. The throwing cylinder is located in the middle and rear of the vehicle and adopts a parabolic shape, which can throw a long distance and realize the function of following the vehicle to catch hay.

[0090] Example 2

[0091] like Figure 5 As shown, a silage harvester of this embodiment includes the aforementioned silage harvesting system and a harvesting head 800. The bottom of the harvesting head 800 is connected to the frame 500 of the silage harvesting head 810 via U-bolts 804. The top rear side of the harvesting head 800 is connected to the frame 500 of the silage harvesting head 810 via a first adjusting rod 805. The middle bottom position of the harvesting head 800 is connected to the frame 500 of the silage harvesting head 810 via a second adjusting rod 806. The bottom front end of the harvesting head 800 is provided with a plurality of mounting plates 803, and each mounting plate 803 is provided with at least one U-bolt 804. The two ends of the U-bolt 804 are respectively locked and fixed to the mounting plate 803 by nuts.

[0092] like Figure 5As shown, the silage harvester in this embodiment is also equipped with a driver's cab 814, which is located behind the silage cutting platform 810 and the ear-picking cutting platform 800. The hay collection box 813 is located below the throwing port of the throwing cylinder 812, and an ear box 815 is also provided below the hay collection box 813.

[0093] Furthermore, such as Figures 7-9 As shown, it also includes support legs 900. In this embodiment, there are at least two support legs 900, with at least one support leg 900 on each side of the ear-picking cutter 800. Providing at least one support leg 900 on each side of the ear-picking cutter 800 provides effective and stable support. By detachably connecting support legs to the ear-picking cutter, the upper ear-picking cutter can be temporarily supported. This ensures that when the operator lowers the cutter from its highest point to its lowest point, the upper ear-picking cutter with the support leg mechanism can touch the ground first. Then, the connection structure between the ear-picking cutter and the silage cutter can be disassembled, and the lower silage cutter can be lowered, thus separating the upper and lower cutters while maintaining a safe distance. The operator can then reverse the vehicle to complete the disassembly of the entire upper ear-picking cutter. To install the ear-picking cutter on the silage cutter, the above steps are reversed to complete the assembly of the ear-picking cutter. With the help of the support legs, the upper ear-picking and cutting platform can be quickly attached or disassembled, and the fixed position of the upper ear-picking and cutting platform can also be moved back and forth.

[0094] like Figure 9 As shown, the support leg 900 in this embodiment includes a vertical support rod 901, a bottom support beam 902, and a top support rod 903. The bottom end of the vertical support rod 901 is vertically connected to the bottom support beam 902, and the top end of the vertical support rod 901 is vertically connected to the top support rod 903. The top support rod 903 is arranged at an angle to the bottom support beam 902. Specifically, the top support rod 903 and the bottom support beam 902 can be arranged vertically. By using the bottom support beam, the weight of the entire harvesting platform can be distributed across the entire beam; by using the top support rod arranged at an angle to the bottom support beam, the harvesting platform can be effectively and stably supported.

[0095] like Figures 7-9 As shown, in this embodiment, the bottom support beam 902 is arranged horizontally, and there are multiple vertical support rods 901. The height of the vertical support rod 901 located in front of the harvesting platform 800 is less than the height of the vertical support rod 901 located behind the harvesting platform 800. By using vertical support rods of different heights, it can be adapted to the inclined harvesting platform.

[0096] like Figure 9As shown, in this embodiment, one optional configuration for the support leg 900 is that there are two vertical support rods 901, each vertically fixed to both ends of the bottom support beam 902. Of course, there can also be multiple vertical support rods 901. A triangular support plate 904 is also provided at the connection point between the vertical support rod 901 and the bottom support beam 902 to stabilize the entire support leg 900 structure and improve its strength.

[0097] In this embodiment, the top end of the support leg 900 is detachably connected to the ear-picking cutter 800 via a pin or bolt, or the top end of the support leg 900 is detachably connected to the ear-picking cutter 800 via a pipe connector. The top end of the support leg 900 can be directly connected to the ear-picking cutter 800 via a pin or bolt, or a pipe connector can be provided at the bottom of the ear-picking cutter 800, the pipe at the top of the support leg 900 can be fitted onto the pipe connector, and then fixedly connected by bolts, etc. Specifically, for example... Figure 3 As shown, the support leg 900 in this embodiment adopts a square tube structure, and the tube connector can also adopt a square tube structure. The top support tube 903 at the top of the support leg 900 can be sleeved in the tube connector, and then the top support tube 903 and the tube connector can be fixedly connected by bolts or pins.

[0098] like Figures 10-15 As shown, in this embodiment, the front bottom of the ear-picking cutter 800 is provided with multiple mounting plates 803, and each mounting plate 803 is provided with at least one U-bolt 804. The two ends of the U-bolt 804 are respectively locked and fixed to the mounting plate 803 by nuts. The mounting plate 803 is arranged at an angle relative to the bottom of the ear-picking cutter 800. By providing multiple mounting plates 803 at the front bottom of the ear-picking cutter 800 and providing at least one U-bolt 804 on each mounting plate 803, the front bottom of the ear-picking cutter 800 can be assembled onto the frame of the silage cutter 810 by the U-bolt 804 on the mounting plate 803, so that the center of the entire ear-picking cutter 800 falls on the receiving position of the lower silage cutter 810. Moreover, by providing a first adjusting rod 805, and by loosening the U-bolt 804 to adjust the center distance of the first adjusting rod 805, the front and rear positions of the ear-picking cutter 800 can be adjusted. When disassembly is required, simply remove the first adjusting rod 805 and the U-bolt 804, thereby disconnecting the connection between the ear-picking header 800 and the silage header 810, thus achieving the disassembly of the silage header 810 and the ear-picking header 800.

[0099] like Figure 13 and Figure 15As shown, in this embodiment, the mounting plate 803 is arranged at an angle relative to the bottom of the ear-picking cutter 800. When the ear-picking cutter 800 is arranged at an angle, the mounting plate 803 is arranged horizontally, which is beneficial for assembly with the lower silage cutter frame.

[0100] like Figures 14-16 As shown, a second adjusting rod 806 is also connected to the bottom center of the ear-picking cutter 800 in this embodiment. It can be held in place by the first adjusting rod 805 at the rear top, and the entire bottom of the ear-picking cutter 800 can be supported by the second adjusting rod 806, which facilitates a stable and reliable connection between the silage cutter and the ear-picking cutter. The number of second adjusting rods 806 can be arbitrarily set as needed, for example, two, three, or more.

[0101] The center distance between the first adjusting rod 805 and the second adjusting rod 806 is adjustable; for example, a rod structure with telescopic length can be used. The length adjustment method for the first adjusting rod 805 and the second adjusting rod 806 can use existing length adjustment methods, such as using a cylinder or hydraulic cylinder. A preferred embodiment of the adjusting rods in this embodiment uses a screw and nut for length adjustment. The first adjusting rod 805 and the second adjusting rod 806 each include a central threaded sleeve and two threaded rods. One end of each threaded rod is threaded to both ends of the threaded sleeve, and the center distance of the adjusting rods can be adjusted by turning the threaded rods. The adjusted rods can also be locked using nuts at both ends of the threaded sleeve. The other ends of the two threaded rods are each equipped with a U-shaped fork, which can be used to connect the silage cutting platform and the ear-picking cutting platform. One threaded rod of the first adjusting rod 805 has a U-shaped fork connected to the rear side of the ear-picking cutter 800 near the upper end, and the other threaded rod has a U-shaped fork connected to the top of the silage cutter; one threaded rod of the second adjusting rod 805 has a U-shaped fork connected to the bottom of the ear-picking cutter 800 near the middle, and the other threaded rod has a U-shaped fork connected to the front upper end of the silage cutter.

[0102] like Figure 12 and Figure 13As shown, the front bottom of the harvesting cutter 800 in this embodiment is provided with a first rectangular tube 807 extending left and right. Multiple second rectangular tubes 808 are spaced apart along the length of the bottom of the first rectangular tube 807. One side of each second rectangular tube 808 has a connecting slope. The second rectangular tube 808 is connected to the bottom plane of the first rectangular tube 807 via the connecting slope on one side, and to the mounting plate 803 via the connecting surface on the other side, so that the mounting plate 803 is arranged at a preset angle to the bottom of the harvesting cutter 800. By providing the first rectangular tube, it is convenient to install multiple second rectangular tubes on the first rectangular tube, and the second rectangular tubes can be evenly distributed on the first rectangular tube. The connecting slope on the second rectangular tube facilitates the connection and fixation of the mounting plate, allowing the mounting plate to be arranged at an angle relative to the bottom of the harvesting cutter.

[0103] like Figures 12-15 As shown, in this embodiment, the first rectangular tube 807 and the second rectangular tube 808 are arranged perpendicularly. The perpendicular arrangement of the first rectangular tube 807 and the second rectangular tube 808 is beneficial for setting a mounting plate 803 of a certain length, so that multiple U-bolts 804 are arranged on the mounting plate 803 in a direction perpendicular to the first rectangular tube 807.

[0104] like Figure 13 As shown, each of the mounting plates 803 in this embodiment is provided with at least two U-bolts 804, and the at least two U-bolts 804 are arranged in the front-back direction.

[0105] A preferred embodiment of this solution is as follows: Figure 12 and Figure 13 As shown, the first rectangular tube 807 can be arranged laterally below the front side of the harvesting platform 800, spanning the left and right directions of the harvesting platform 800. A second rectangular tube 808 can be installed below each of the left and right ends of the first rectangular tube 807, with the length of the second rectangular tube 808 slightly greater than the width of the first rectangular tube 807. A mounting plate 803 is then installed at the bottom of the second rectangular tube 808, with its length perpendicular to the first rectangular tube 807. U-bolts 804 are installed near both ends of the mounting plate 803 along its length. The number of U-bolts can be arbitrarily set; their purpose is to secure the silage harvesting platform frame. In this embodiment, two U-bolts 804 are installed on each mounting plate 803.

[0106] In this embodiment, multiple mounting plates 803 are provided at the bottom front end of the ear-picking cutter 800, and at least one U-bolt 804 is provided on each mounting plate 803. The bottom front end of the ear-picking cutter 800 can be assembled onto the frame of the silage cutter via the U-bolt 804 on the mounting plate 803, so that the center of the entire ear-picking cutter 800 falls on the receiving position of the lower silage cutter. Furthermore, by providing a first adjusting rod 805, and by loosening the U-bolt 804 to adjust the center distance of the first adjusting rod 805, the front and rear positions of the ear-picking cutter 800 can be adjusted.

[0107] like Figure 14 and Figure 15 As shown, in this embodiment, the frame of the silage harvester 810 is provided with a third rectangular tube 809 arranged front and rear, and the U-bolt 804 is wrapped around the corresponding third rectangular tube 809. The third rectangular tube makes the connection between the silage harvester and the ear-picking harvester more firm and stable.

[0108] like Figure 10 and Figure 12 As shown, in this embodiment, a belt conveyor 801 connected to the ear lifter 802 is located below the rear end of the ear-picking cutter 800. When the front and rear positions of the ear-picking cutter 800 are adjustable, the belt conveyor 801 can be installed to avoid gaps after adjustment and to prevent ear accumulation inside the ear-picking cutter 800.

[0109] The silage harvesting system of this embodiment feeds material from a cutting and feeding disc, and then transports it via vertical conveyor wheels, which improves the feeding volume and conveying efficiency. The rear feeding and chopping modules compact and cut the fed stalks. The chopped material is then thrown backward through a throwing module and a throwing cylinder. The throwing cylinder is located in the middle-rear part of the vehicle and has a parabolic shape, resulting in a long throwing distance and enabling it to catch the silage from the vehicle. Multiple mounting plates are installed at the bottom front end of the ear-picking cutter, and each mounting plate has at least one U-bolt. These U-bolts allow the bottom front end of the ear-picking cutter to be mounted on the frame of the silage cutter, ensuring the center of the entire ear-picking cutter rests on the receiving position of the lower silage cutter. Furthermore, by setting a first and a second adjusting rod, and by loosening the U-bolts to adjust the center distance between the first and second adjusting rods, the front-rear position of the ear-picking cutter body can be adjusted.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
