Description

Technical Field

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

[0002] The dual-purpose silage harvester's function dictates that it possesses both silage and corn harvesting capabilities, requiring independent processing capacity for both stalks and ears of grain—a combination of practical functions such as ear picking, peeling, feeding, chopping, and spraying. Existing silage harvester transmission systems suffer from inefficient layouts and insufficient material processing capacity. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a silage harvester transmission 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 harvester transmission system includes a power mechanism, a chopping blade shaft, a first cutter shaft, and a second cutter shaft. The power mechanism is drivenly connected to the chopping blade shaft. One end of the chopping blade shaft is drivenly connected to the first cutter shaft. The first power output end of the first cutter 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 cutter shaft is connected to the upper ear-picking cutter. The second power output end of the first cutter shaft also transmits power to the second cutter shaft through a gear set. The first power output end of the second cutter 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 cutter disc drive gearbox. The second power output end of the second cutter shaft is drivenly connected to both the lower cutter disc drive gearbox and the lower cutter conveyor wheel drive gearbox.

[0005] The beneficial effects of this invention are as follows: The transmission system of the silage harvester of this invention transmits power to two header shafts through a 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 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 split into left and right input power through the second header shaft, ensuring the operability of the transmission.

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

[0007] 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 by driving the front lower roller sprocket. The front lower roller sprocket is connected to the rear lower roller sprocket of the power input end of the rear lower roller. 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.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it facilitates power transmission by transmitting power through sprockets and chains.

[0009] 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 double-row transmission sprocket on the first header shaft.

[0010] The beneficial effect of adopting the above-mentioned further solution is that bidirectional power transmission can be achieved through the double-row sprockets.

[0011] Furthermore, 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.

[0012] 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.

[0013] 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.

[0014] Furthermore, 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.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting floating holes, floating space is provided for the front upper roller and the rear upper roller.

[0016] Furthermore, the second power output end of the second cutting table shaft is connected to the lower cutting table conveyor wheel drive gearbox via the input sprocket of the lower cutting table conveyor wheel transmission box.

[0017] Furthermore, the power mechanism includes an engine, the power output end of which is connected to the power input end of the intermediate shaft, and the power output end of the intermediate shaft is connected to the power input end of the shredder shaft via a belt.

[0018] Furthermore, two shredding rollers are mounted side by side on the shredding shaft, and the shredding blades on the two shredding rollers are staggered and arranged at an angle.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the shredding roller structure has a large shredding area and strong shredding capacity, which can ensure the control of shredding quality and cutting length.

[0020] A silage harvester includes the aforementioned silage harvester transmission system.

[0021] The beneficial effects of the present invention are: the green and yellow silage harvester of the present invention adopts a reasonable power system layout, which is arranged in an assembly line, with strong material processing capacity and high chopping quality. Attached Figure Description

[0032] Example 1

[0033] like Figure 1As shown, a silage harvester transmission system of this embodiment includes a power mechanism 100, a chopping blade shaft 200, a first header shaft 300, and a second header shaft 400. The power mechanism 100 is drivenly connected to the chopping blade shaft 200. One end of the chopping blade shaft 200 is drivenly connected to the first header shaft 300. The first power output end of the first header shaft 300 is drivenly connected to the power input end of the rear upper roller 302. The power output end of the rear upper roller 302 is drivenly connected to the power input end of the front upper roller 301. The second power output end of the first header shaft 300 is connected to the upper ear-picking header input sprocket 402, and the power is driven by the upper ear-picking header input sprocket 402. The force is transmitted to the upper harvesting header. The second power output end of the first header shaft 300 also transmits the power to the second header shaft 400 through the gear set 405. The first power output end of the second header 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 header disc. The power is drawn in from the right side of the entire transmission system through the front lower roller. The second power output end of the second header shaft 400 is connected to the drive gear box 103 of the lower header disc and the drive gear box 102 of the lower header conveyor wheel. The power is drawn in from the left side of the entire system through the second power output end of the second header shaft 400.

[0034] like Figure 1 As 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.

[0035] like Figure 1 As shown, the power output end of the chopping blade shaft 200 in this embodiment is provided 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, 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 double-row sprockets enable bidirectional power transmission.

[0036] 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.

[0037] like Figures 1-3 As 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.

[0038] like Figure 2 and Figure 3As 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.

[0039] like Figure 1 As 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.

[0040] 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.

[0041] 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.

[0042] The transmission process of the silage harvester transmission system in this embodiment is as follows: Figure 1As 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. The first header shaft 300 on the left side of the double-row drive sprocket 311 is also equipped with a transmission gear. The transmission gear and the gear set 405 composed of other gears meshing with the transmission gear transmit power to the upper header shaft 300. The force is transmitted backward 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 backward 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.

[0043] 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 and the second header shaft 400. Then, the second header shaft 400 further 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.
