Description

Technical Field

[0001] This utility model relates to the field of silage harvester equipment, and in particular to a silage harvester feeding transmission device. Background Technology

[0002] Existing forage harvester feeding structures typically include an upper feeding roller assembly and a lower feeding roller assembly, powered by two hydraulic motors. These two hydraulic motors are usually connected in series or in parallel. While a series connection ensures consistent speed, the hydraulic oil needs to pass through both motors, leading to additional friction and pressure losses, potentially reducing overall system efficiency. A parallel connection, with separate oil circuits for each motor, can result in inconsistent motor speeds due to varying resistance from the material to the upper and lower feeding roller assemblies, potentially causing blockages in the forage harvester's feeding structure. Utility Model Content

[0003] The purpose of this invention is to provide a feeding transmission device for a silage harvester, which solves the problems of existing transmission devices being unable to simultaneously address the blockage of the silage harvester's feeding structure and the low efficiency of the silage harvester. This improves the efficiency of the silage harvester while effectively reducing the blockage of the silage harvester's feeding structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a feeding transmission device for a silage harvester, the silage harvester including an upper feeding roller assembly and a lower feeding roller assembly, the feeding transmission device including two hydraulic motors that drive the upper feeding roller assembly and the lower feeding roller assembly respectively, the oil circuits of the two hydraulic motors being connected in parallel, a reversing component being provided at the output end of one of the two hydraulic motors, and a linkage component being provided between the output ends of the two hydraulic motors, the linkage component being used to connect the reversing component on the output end of one hydraulic motor and the output end of the other hydraulic motor, so that the output ends of the two hydraulic motors move synchronously.

[0005] After adopting the above technical solution, this utility model has the following advantages: The parallel connection of the oil circuits of the two hydraulic motors reduces the additional friction and pressure loss caused by the hydraulic oil passing through multiple hydraulic motors in the existing series connection method, thereby improving the efficiency of the forage harvester. Secondly, since the upper feed roller assembly and the lower feed roller assembly rotate in opposite directions, the output ends of the two hydraulic motors rotate in different directions. The reversing assembly can reverse the power transmitted through the linkage assembly, ensuring coordinated movement between the two hydraulic motors. Without affecting the rotation direction of the two hydraulic motors, the output speeds of the two hydraulic motors are kept as consistent as possible, solving the problem of inconsistent speeds that may occur in parallel connection, improving the stability of the feeding process, and effectively reducing the blockage of the upper feed roller assembly and the lower feed roller assembly of the forage harvester.

[0006] Furthermore, the reversing assembly includes a first gear and a second gear that mesh with each other. The first gear is fixedly connected to the output end of the hydraulic motor, and the second gear is used for transmission connection with the linkage assembly.

[0007] Using the aforementioned technical solution, when the two hydraulic motors rotate in different directions, they can still maintain synchronous movement through the linkage component by meshing the first gear and the second gear, thus ensuring coordinated movement between the two hydraulic motors.

[0008] Furthermore, the linkage assembly includes two drive sprockets and a drive chain for connecting the two drive sprockets, wherein one of the drive sprockets is fixedly connected to the second gear and is coaxial, and the other drive sprocket is connected to the output end of another hydraulic motor that does not have a reversing assembly.

[0009] Using the aforementioned technical solution, the sprocket drive has high transmission efficiency, reduces energy loss, improves the overall energy efficiency ratio of the system, and can also withstand large torque, ensuring that the two hydraulic motors can achieve high-speed rotation.

[0010] Furthermore, it also includes a tension wheel, a lever, a tension spring, and a support. The lever is rotatably connected to the support, and the tension wheel is rotatably connected to one end of the lever. The end of the lever with the tension wheel is connected to the body of the silage harvester through the tension spring so that the tension wheel drive chain is in contact.

[0011] Using the aforementioned technical solution, the tensioning wheel is connected to the forage harvester body via levers and tension springs, enabling it to automatically adjust its position and ensure that the drive chain is always under proper tension. This helps reduce slack in the drive chain, preventing tooth skipping or detachment caused by a loose drive chain, and improving the stability and reliability of the transmission system.

[0012] Furthermore, an adjusting bolt is provided at the end of the lever away from the tension wheel. The adjusting bolt is threadedly connected to the body of the silage harvester. The lever is slidably connected to the adjusting bolt. A nut is provided on the adjusting bolt. The nut is located on the side of the lever away from the tension spring to fix the position of the lever.

[0013] By adjusting the bolt and nut, the position of the tension wheel can be adjusted more precisely and conveniently by adjusting the position of the nut on the adjusting bolt. This adjusts the pressure of the tension wheel on the transmission chain, ensuring that the transmission chain is always in the expected tension state.

[0014] Furthermore, it also includes a speed sensor for monitoring the speed of the two hydraulic motors.

[0015] The above technical solution uses a speed sensor to monitor the speed of the two hydraulic motors in real time, ensuring that the feeding transmission device of the silage machine can detect abnormal speed in a timely manner during operation. This allows for more precise control of the synchronous movement of the two hydraulic motors, ensuring coordinated operation between the upper and lower feeding roller assemblies as much as possible, thereby reducing material jamming or accumulation.

[0016] Furthermore, the silage harvester includes a feeding component frame, and the silage harvester feeding transmission device also includes a connecting seat, a first mounting seat for mounting one of the hydraulic motors, and a second mounting seat for mounting the other hydraulic motor. The first mounting seat and the feeding component frame are detachably connected, and the second mounting seat and the feeding component frame are detachably connected. The hydraulic motor and the first mounting seat are connected by a connecting seat, and the output end of the hydraulic motor passes through the connecting seat. The connecting seat has an opening for the linkage component to pass through.

[0017] Through the above technical solution, the design of the feeding component frame, the first mounting base and the second mounting base allows each component to be installed and disassembled independently, which facilitates the assembly and maintenance of the equipment. It also allows the position and angle of the hydraulic motor to be easily adjusted during the commissioning process, ensuring the correct installation and working state of the linkage component. Furthermore, the connecting base is provided with an opening for the linkage component to pass through, ensuring that the linkage component can smoothly transmit power while maintaining the stability of the structure.

[0018] Furthermore, the upper feed roller assembly includes a front upper roller, a rear upper roller, and a gearbox, and the lower feed roller assembly includes a front lower roller, a rear lower roller, and a sprocket box. One of the hydraulic motors is drivenly connected to one of the front upper roller and the rear upper roller, and the other hydraulic motor is drivenly connected to one of the front lower roller and the rear lower roller. The front upper roller and the rear upper roller are drivenly connected through the gearbox, and the front lower roller and the rear lower roller are drivenly connected through the sprocket box.

[0019] Through the above technical solution, the front upper roller and the rear upper roller are connected by a gearbox, and the front lower roller and the rear lower roller are connected by a sprocket box. This ensures the synchronous movement of the front upper roller and the rear upper roller, as well as the front lower roller and the rear lower roller, as much as possible, avoiding material jamming or accumulation. It also ensures efficient power transmission and reduces power loss.

[0020] Furthermore, the two hydraulic motors are respectively connected to the upper rear roller and the lower rear roller; or, the two hydraulic motors are respectively connected to the upper front roller and the lower front roller.

[0021] By using the above technical solution, when two rollers on the same side are driven by a hydraulic motor, the synchronous movement between the two rollers can be better ensured, further avoiding material jamming or accumulation caused by asynchrony.

[0022] Furthermore, the forage machine also includes a feeding component frame, with the gearbox and sprocket box located on the same side of the feeding component frame, and the two hydraulic motors located on the other side of the feeding component frame.

[0023] By using the above technical solution, placing two hydraulic motors on the same side can simplify the design of the linkage components, making the connection of the linkage components more direct and reducing intermediate links. This reduces the transmission path of the linkage components, thereby reducing friction and energy loss during transmission and improving transmission efficiency. Furthermore, by concentrating the gearbox and sprocket box on one side and placing the hydraulic motors on the other side, the weight distribution of the equipment can be made more uniform, reducing vibration and imbalance during equipment operation.

[0041] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] like Figures 1 to 6 As shown, this utility model provides a feeding transmission device for a silage harvester, mainly applicable to silage harvesters. The silage harvester includes a feeding component frame 10, an upper feeding roller assembly, and a lower feeding roller assembly. The upper and lower feeding roller assemblies are arranged vertically and rotate in opposite directions. Material enters between the upper and lower feeding roller assemblies. The silage harvester feeding transmission device includes two hydraulic motors 20 that drive the upper and lower feeding roller assemblies respectively. The oil circuits of the two hydraulic motors 20 are connected in parallel. One of the hydraulic motors 20 has a reversing component at its output end. A linkage component is provided between the output ends of the two hydraulic motors 20. The linkage component is used to connect the reversing component on the output end of one hydraulic motor 20 and the output end of the other hydraulic motor 20, so that the output ends of the two hydraulic motors 20 move synchronously.

[0043] The parallel connection of the oil circuits of the two hydraulic motors 20 reduces the additional friction and pressure loss caused by the hydraulic oil passing through multiple hydraulic motors 20 in the existing series connection method, thus improving the efficiency of the forage harvester. Secondly, since the upper and lower feed roller assemblies rotate in opposite directions, the output rotation directions of the two hydraulic motors 20 are different. The reversing assembly can reverse the power transmitted through the linkage assembly, ensuring coordinated movement between the two hydraulic motors 20. This maintains the rotation direction of the two hydraulic motors 20 while keeping their output speeds as consistent as possible, solving the problem of inconsistent speeds that may occur in parallel connection methods. This improves the stability of the feeding process and effectively reduces clogging of the upper and lower feed roller assemblies of the forage harvester. For example, the hydraulic motor 20 with a higher output speed can drive the output of the other hydraulic motor 20 to move synchronously through the linkage and reversing assemblies. Similarly, the hydraulic motor 20 with a lower output speed can drive the output of the other hydraulic motor 20 to move synchronously through the linkage and reversing assemblies.

[0044] The feeding upper roller assembly includes a front upper roller 11, a rear upper roller 12, and a gearbox 13. The feeding lower roller assembly includes a front lower roller 14, a rear lower roller 15, and a sprocket box 16. One hydraulic motor 20 is connected to one of the front upper rollers 11 and the rear upper roller 12, and another hydraulic motor 20 is connected to one of the front lower rollers 14 and the rear lower roller 15. The front upper roller 11 and the rear upper roller 12 are connected via the gearbox 13, and the front lower roller 14 and the rear lower roller 15 are connected via the sprocket box 16. This design ensures synchronous movement between the front upper rollers 11 and 12, and between the front lower rollers 14 and 15, preventing material jamming or accumulation, and ensuring efficient power transmission while reducing power loss.

[0045] To improve transmission efficiency, the forage harvester also includes a feeding component frame 10, with the gearbox 13 and sprocket box 16 located on the same side of the feeding component frame 10, and two hydraulic motors 20 located on the other side. Placing the two hydraulic motors 20 on the same side simplifies the design of the linkage components, making the connection more direct and reducing intermediate links. This reduces the transmission path of the linkage components, thereby reducing friction and energy loss during transmission and improving transmission efficiency. Furthermore, by concentrating the gearbox 13 and sprocket box 16 on one side and placing the hydraulic motors 20 on the other, a more uniform weight distribution can be achieved, reducing vibration and imbalance during operation.

[0046] In this embodiment, the silage machine feeding transmission device further includes a first mounting base 22 for mounting one of the hydraulic motors 20, a second mounting base 23 for mounting the other hydraulic motor 20, and a connecting base 21. The first mounting base 22 and the feeding component frame 10 are detachably connected, as are the second mounting base 23 and the feeding component frame 10. The hydraulic motor 20 and the first mounting base 22 are connected via the connecting base 21, with the output end of the hydraulic motor 20 passing through the connecting base 21. The connecting base 21 has an opening 24 for the linkage component to pass through. The design of the feeding component frame 10, the first mounting base 22, and the second mounting base 23 allows each component to be installed and disassembled independently, facilitating equipment assembly and maintenance. It also allows for easy adjustment of the position and angle of the hydraulic motor 20 during commissioning, ensuring the correct installation and working state of the linkage component. Furthermore, the opening 24 in the connecting base 21 ensures that the linkage component can smoothly transmit power while maintaining structural stability.

[0047] Specifically, the first mounting base 22, the second mounting base 23, the connecting base 21, the feeding component frame 10, and the hydraulic motor 20 can be connected by bolts.

[0048] The two hydraulic motors 20 are respectively connected to the upper rear roller 12 and the lower rear roller 15. When the two rollers on the same side are driven by the hydraulic motors 20, the synchronous movement between the two rollers can be better ensured, and the material jamming or accumulation caused by asynchrony can be further avoided.

[0049] Specifically, the first mounting base 22 is located above the second mounting base 23. The hydraulic motor 20 mounted on the first mounting base 22 drives the upper feed roller assembly, and the hydraulic motor 20 mounted on the second mounting base 23 drives the lower feed roller assembly. Specifically, the hydraulic motor 20 mounted on the first mounting base 22 is connected to the universal joint 27. The universal joint 27, the front upper roller 11, and the rear upper roller 12 are all connected to the gearbox 13 to complete the power transmission. The output end of the hydraulic motor 20 mounted on the second mounting base 23 is connected to the rear lower roller 15 through the chain coupling 28. The rear lower roller 15 is connected to the front lower roller 14 through the sprocket box 16 to complete the power transmission.

[0050] Specifically, the reversing assembly is located on the hydraulic motor 20 that drives the feed roller assembly. The reversing assembly includes a first gear 40 and a second gear 41 that mesh with each other. The first gear 40 is fixedly connected to the output end of the hydraulic motor 20, and the second gear 41 is used for transmission connection with the linkage assembly. The first gear 40 and the second gear 41 can change the output direction of the power while transmitting power.

[0051] The linkage assembly includes two drive sprockets 30 and a drive chain 31 connecting the two drive sprockets 30. One drive sprocket 30 is fixedly connected to and coaxial with the second gear 41, while the other drive sprocket 30 is connected to the output end of another hydraulic motor 20 without a reversing assembly. The sprocket drive has high transmission efficiency, reduces energy loss, and improves the overall energy efficiency ratio of the system. The sprocket drive can also withstand large torques, ensuring high-speed rotation of the two hydraulic motors 20.

[0052] Specifically, the second mounting base 23 is provided with a fixed shaft 25, on which a transmission sprocket 30 and a second gear 41 are fixed. The fixed shaft 25 and the second mounting base 23 are connected by welding to form an integral structure, which helps to ensure the installation accuracy of the fixed shaft 25 as much as possible and strengthens the connection between the mounting shaft and the second mounting base 23.

[0053] To improve the installation reliability of the transmission sprocket 30, retaining rings 26 are provided on both sides of the transmission sprocket 30 to limit the movement of the transmission sprocket 30.

[0054] Because the transmission chain 31 is prone to loosening during long-term use, resulting in unstable power transmission between the two hydraulic motors 20, this embodiment also includes a tension wheel 50, a lever 51, a tension spring 52, and a support 53. The lever 51 is rotatably connected to the support 53, and the tension wheel 50 is rotatably connected to one end of the lever 51. The end of the lever 51 with the tension wheel 50 is connected to the body of the silage harvester through the tension spring 52, so that the tension wheel 50 contacts the transmission chain 31. This helps to reduce the loosening of the transmission chain 31, avoids tooth skipping or falling off caused by the loosening of the transmission chain 31, and improves the stability and reliability of the transmission system.

[0055] Lever 51 is rotatably connected to support 53 via a pivot. To facilitate adjustment of the tension of the drive chain 31, an adjusting bolt 54 is provided at the end of lever 51 away from the tension wheel 50. The adjusting bolt 54 is threadedly connected to the body of the silage harvester and is perpendicular to the pivot. Lever 51 has a through hole through which the adjusting bolt 54 passes. Lever 51 and adjusting bolt 54 are slidably connected. A nut 55 is provided on the adjusting bolt 54, located on the side of lever 51 away from the tension spring 52, to fix the position of lever 51. By simply adjusting the position of nut 55 on adjusting bolt 54, the position of tension wheel 50 can be adjusted more precisely and conveniently, thereby adjusting the pressure of tension wheel 50 on drive chain 31 and ensuring that drive chain 31 is always in the expected tension state. After drive chain 31 is adjusted to the appropriate tension, tighten adjusting bolt 54 until the head of adjusting bolt 54 hits the body of silage harvester, and then fix it with nut 55.

[0056] To ensure more stable tension on the transmission chain 31, two tension springs 52 can be provided, with the two tension springs 52 located on both sides of the tension wheel 50, so that the tension wheel 50 is subjected to more balanced forces.

[0057] It should be noted that, in this embodiment, the body of the aforementioned silage harvester specifically refers to the connecting seat 21.

[0058] To make the rotational speed of the two hydraulic motors 20 more intuitive, a speed sensor 60 is also included to monitor the rotational speed of the two hydraulic motors 20. This ensures that the feeding transmission device of the silage machine can detect abnormal rotational speed in a timely manner during operation, and can more accurately control the synchronous movement of the two hydraulic motors 20. This ensures the coordinated operation between the upper feeding roller assembly and the lower feeding roller assembly as much as possible, thereby reducing material jamming or accumulation.

[0059] The speed sensor 60 can be provided in two places. The two speed sensors 60 can be located on the first mounting base 22 and the second mounting base 23 respectively. The speed sensor 60 can obtain the speed of the hydraulic motor 20 by detecting the speed of the output end of the hydraulic motor 20.

[0060] Understandably, in other embodiments, the linkage component may also be a pulley and a drive belt, which connects two hydraulic motors, resulting in less noise.

[0061] Understandably, in other embodiments, when the distance between the two hydraulic motors is relatively short, gear transmission can also be used directly to make the movement of the two hydraulic motors more synchronized.

[0062] Understandably, in other embodiments, the two hydraulic motors may also be connected to the upper front roller and the lower front roller respectively. Driving the two rollers on the same side with hydraulic motors better ensures synchronized movement between the two rollers, further preventing material jamming or accumulation due to asynchrony.

[0063] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
