Description

Technical Field

[0001] The invention relates to the field of silage machine equipment, in particular to a silage machine feeding transmission device. Background Art

[0002] The feeding structure of the silage machine in the prior art usually includes an upper feeding roller assembly and a lower feeding roller assembly, and two hydraulic motors are used as power devices to drive the upper feeding roller assembly and the lower feeding roller assembly. The two hydraulic motors are usually connected in series or in parallel. Although the series connection can ensure consistent rotation speed, the hydraulic oil needs to pass through two hydraulic motors, resulting in additional friction and pressure loss, which may reduce the overall system efficiency. In the parallel connection, because the two motors have separate oil circuits, the material has different resistance to the upper feeding roller assembly and the lower feeding roller assembly, so it is possible that the rotation speeds of the two hydraulic motors are inconsistent, which will cause the problem of clogging of the silage machine's feeding structure. Summary of the invention

[0003] The purpose of the present invention is to provide a silage machine feeding transmission device, which solves the problem that the transmission device in the prior art cannot simultaneously solve the blockage of the silage machine's feeding structure and the low efficiency of the silage machine, while improving the efficiency of the silage machine, effectively reducing the blockage of the silage machine's feeding structure.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a feeding transmission device for a silage machine, the silage machine includes a feeding upper roller assembly and a feeding lower roller assembly, the feeding transmission device for the silage machine includes two hydraulic motors that respectively drive the feeding upper roller assembly and the feeding lower roller assembly, the oil circuits of the two hydraulic motors are connected in parallel, the output end of one of the two hydraulic motors is provided with a reversing assembly, and a linkage assembly is provided between the output ends of the two hydraulic motors, and the linkage assembly is used to connect the reversing assembly on the output end of one of the hydraulic motors 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 scheme, the present invention has the following advantages: the oil circuits of the two hydraulic motors are connected in parallel, which reduces the additional friction and pressure loss caused by the hydraulic oil passing through multiple hydraulic motors in the series connection mode of the prior art, thereby improving the efficiency of the silage machine; secondly, since the rotation directions of the feeding upper roller assembly and the feeding lower roller assembly are opposite, the output ends of the two hydraulic motors rotate in different directions. The power transmitted through the linkage assembly can be reversed by the reversing assembly to ensure the coordinated movement between the two hydraulic motors. The rotation directions of the two hydraulic motors are not affected, and the rotation speeds of the output ends of the two hydraulic motors are kept consistent as much as possible, thereby solving the problem of inconsistent rotation speeds that may occur in the parallel mode, improving the stability of the feeding process, and effectively reducing the blockage of the feeding upper roller assembly and the feeding lower roller assembly of the silage machine.

[0006] Furthermore, the reversing assembly includes a first gear and a second gear meshing 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] By adopting the above technical solution, when the two hydraulic motors rotate in different directions, through the meshing of the first gear and the second gear, the two hydraulic motors can still maintain synchronous movement through the linkage assembly, thereby ensuring coordinated movement between the two hydraulic motors.

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

[0009] By adopting the above-mentioned technical solution, the sprocket drive has a higher transmission efficiency, reduces energy loss, and improves the overall energy efficiency ratio of the system. The sprocket drive can also withstand a larger torque to ensure that the two hydraulic motors can rotate at high speed.

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

[0011] With the above technical solution, the tension wheel is connected to the body of the silage machine through a lever and a tension spring, and can automatically adjust its position to ensure that the transmission chain is always in a properly tensioned state. This helps to reduce the slack of the transmission chain, avoid tooth jumping or falling caused by loose transmission chain, and improve the stability and reliability of the transmission system.

[0012] Furthermore, an adjusting bolt is provided at one end of the lever away from the tensioning wheel, the adjusting bolt is threadedly connected to the body of the silage machine, the lever is slidably connected to the adjusting bolt, a nut is provided on the adjusting bolt, and the nut is located on the side of the lever away from the tensioning spring to fix the position of the lever.

[0013] Through the above technical solution, by adjusting the cooperation between the bolt and the nut, it is only necessary to adjust the position of the nut on the adjusting bolt, so that the position of the tensioner can be adjusted more accurately and conveniently, thereby adjusting the pressure of the tensioner on the transmission chain to ensure 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] Through the above technical solution, the speed of the two hydraulic motors is monitored in real time by the speed sensor, ensuring that the silage machine feeding transmission device can detect abnormal speed in time during operation, and can more accurately control the synchronous movement of the two hydraulic motors, ensuring the coordinated operation between the feeding upper roller assembly and the feeding lower roller assembly as much as possible, thereby reducing material jamming or accumulation.

[0016] Furthermore, the silage machine includes a feeding component frame, and the silage machine 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, the second mounting seat and the feeding component frame are detachably connected, the hydraulic motor and the first mounting seat are connected via a connecting seat, the output end of the hydraulic motor passes through the connecting seat, and the connecting seat is provided with an opening for the linkage assembly to pass through.

[0017] Through the above technical solution, the design of the feeding component frame, the first mounting seat and the second mounting seat allows each component to be independently installed and disassembled, which is convenient for the assembly and maintenance of the equipment, and makes it easy to adjust the position and angle of the hydraulic motor during the debugging process to ensure the correct installation and working state of the linkage component. In addition, the connecting seat 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 feeding upper roller assembly includes a front upper roller, a rear upper roller and a gear box, and the feeding lower roller assembly includes a front lower roller, a rear lower roller and a sprocket box, one of the hydraulic motors is transmission-connected to one of the front upper roller and the rear upper roller, and the other hydraulic motor is transmission-connected to one of the front lower roller and the rear lower roller, the front upper roller and the rear upper roller are transmission-connected via a gear box, and the front lower roller and the rear lower roller are transmission-connected via a sprocket box.

[0019] Through the above technical scheme, the front upper roller and the rear upper roller are connected by a gear box transmission, and the front lower roller and the rear lower roller are connected by a sprocket box transmission, which ensures the synchronous movement between the front upper roller and the rear upper roller, and the front lower roller and the rear lower roller as much as possible, avoids material jamming or accumulation, and also ensures efficient power transmission and reduces power loss.

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

[0021] Through the above technical solution, when the two rollers on the same side are driven by the hydraulic motor, the synchronous movement between the two rollers can be better ensured, and the jamming or accumulation of materials caused by asynchronism can be further avoided.

In addition, by concentrating the gear box and the sprocket box on the same side and the hydraulic motor on the other side, the weight distribution of the equipment can be more uniform, reducing the vibration and imbalance of the equipment during operation.

[0041] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] like Figures 1 to 6 As shown, the present invention provides a feeding transmission device for a silage machine, which is mainly suitable for silage machines. The silage machine includes a feeding component frame 10, a feeding upper roller assembly and a feeding lower roller assembly. The feeding upper roller assembly and the feeding lower roller assembly are arranged up and down, and the rotation directions of the feeding upper roller assembly and the feeding lower roller assembly are opposite. The material enters from between the feeding upper roller assembly and the feeding lower roller assembly. The feeding transmission device for the silage machine includes two hydraulic motors 20 that drive the feeding upper roller assembly and the feeding lower roller assembly respectively. The oil circuits of the two hydraulic motors 20 are connected in parallel. A reversing assembly is provided at the output end of one of the two hydraulic motors 20. A linkage assembly is provided between the output ends of the two hydraulic motors 20. The linkage assembly is used to connect the reversing assembly on the output end of one of the hydraulic motors 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 oil circuits of the two hydraulic motors 20 are connected in parallel, which reduces the additional friction and pressure loss caused by the hydraulic oil passing through multiple hydraulic motors 20 in the prior art series connection, and improves the efficiency of the silage machine. Secondly, since the rotation directions of the feeding upper roller assembly and the feeding lower roller assembly are opposite, the output ends of the two hydraulic motors 20 rotate in different directions. The reversing assembly can reverse the power transmitted through the linkage assembly to ensure the coordinated movement between the two hydraulic motors 20. Without affecting the rotation direction of the two hydraulic motors 20, the output end speeds of the two hydraulic motors 20 are kept consistent as much as possible, which solves the problem of inconsistent speeds that may occur in the parallel connection mode, improves the stability of the feeding process, and effectively reduces the blockage of the feeding upper roller assembly and the feeding lower roller assembly of the silage machine. For example, a hydraulic motor 20 with a higher output end speed can drive the output end of another hydraulic motor 20 to move synchronously through the linkage assembly and the reversing assembly. For example, a hydraulic motor 20 with a lower output end speed can drive the output end of another hydraulic motor 20 to move synchronously through the linkage assembly and the reversing assembly.

[0044] Among them, the feeding upper roller assembly includes a front upper roller 11, a rear upper roller 12 and a gear box 13, and 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 roller 11 and the rear upper roller 12, and the other hydraulic motor 20 is connected to one of the front lower roller 14 and the rear lower roller 15. The front upper roller 11 and the rear upper roller 12 are connected to each other through the gear box 13, and the front lower roller 14 and the rear lower roller 15 are connected to each other through the sprocket box 16. The synchronous movement between the front upper roller 11 and the rear upper roller 12, and the front lower roller 14 and the rear lower roller 15 is ensured as much as possible, avoiding material jamming or accumulation, and ensuring efficient power transmission and reducing power loss.

[0045] In order to improve the transmission efficiency, the silage machine further includes a feeding component frame 10, a gear box 13 and a sprocket box 16 are located on the same side of the feeding component frame 10, and two hydraulic motors 20 are located on the other side of the feeding component frame 10. Arranging the two hydraulic motors 20 on the same side can simplify the design of the linkage assembly, the connection of the linkage assembly is more direct, the intermediate links are reduced, and the transmission path of the linkage assembly can be reduced, thereby reducing the friction and energy loss during the transmission process, improving the transmission efficiency, and, by centrally arranging the gear box 13 and the sprocket box 16 on the same side and arranging the hydraulic motors 20 on the other side, the weight distribution of the equipment can be more uniform, and the vibration and imbalance of the equipment during operation can be reduced.

[0046] In this embodiment, the feeding transmission device of the silage machine also includes a first mounting seat 22 for mounting one of the hydraulic motors 20, a second mounting seat 23 for mounting the other hydraulic motor 20, and a connecting seat 21. The first mounting seat 22 and the feeding component frame 10 are detachably connected, and the second mounting seat 23 and the feeding component frame 10 are detachably connected. The hydraulic motor 20 and the first mounting seat 22 are connected through the connecting seat 21. The output end of the hydraulic motor 20 passes through the connecting seat 21, and the connecting seat 21 is provided with an opening 24 for the linkage component to pass through. The design of the feeding component frame 10, the first mounting seat 22 and the second mounting seat 23 allows each component to be independently installed and disassembled, which is convenient for the assembly and maintenance of the equipment, so that the position and angle of the hydraulic motor 20 can be easily adjusted during the debugging process to ensure the correct installation and working state of the linkage component, and the connecting seat 21 is provided with an opening 24 for the linkage component to pass through, ensuring that the linkage component can smoothly transmit power while maintaining the stability of the structure.

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

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

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

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

[0052] Specifically, a fixed shaft 25 is provided on the second mounting seat 23, wherein a transmission sprocket 30 and a second gear 41 are fixed on the fixed shaft 25, and the fixed shaft 25 and the second mounting seat 23 are connected into an integrated structure by welding, which is beneficial to ensure the installation accuracy of the fixed shaft 25 as much as possible and enhance the strength of the connection between the mounting shaft and the second mounting seat 23.

[0053] In order to improve the installation reliability of the transmission sprocket 30 , retaining springs 26 are respectively provided on both sides of the transmission sprocket 30 to limit the transmission sprocket 30 .

[0054] Since the transmission chain 31 is prone to loosen during long-term use, the power between the two hydraulic motors 20 cannot be transmitted stably. For this reason, the present embodiment also includes a tensioning wheel 50, a lever 51, a tensioning spring 52 and a support 53. The lever 51 is rotatably connected to the support 53, and the tensioning wheel 50 is rotatably connected to one end of the lever 51. One end of the lever 51 having the tensioning wheel 50 is connected to the body of the silage machine through the tensioning spring 52 so that the tensioning wheel 50 contacts the transmission chain 31, which helps to reduce the looseness of the transmission chain 31, avoid tooth jumping or falling off caused by loose transmission chain 31, and improve the stability and reliability of the transmission system.

[0055] The lever 51 is rotatably connected to the support 53 through a rotating shaft. In order to facilitate the adjustment of the tightness of the transmission chain 31, an adjusting bolt 54 is provided at one end of the lever 51 away from the tensioning wheel 50. The adjusting bolt 54 is threadedly connected to the body of the silage machine. The adjusting bolt 54 is perpendicular to the rotating shaft. A through hole is provided on the lever 51 for the adjusting bolt 54 to pass through. The lever 51 is slidably connected with the adjusting bolt 54. A nut 55 is provided on the adjusting bolt 54. The nut 55 is located on the side of the lever 51 away from the tensioning spring 52 to fix the position of the lever 51. Only by adjusting the position of the nut 55 on the adjusting bolt 54, the position of the tensioning wheel 50 can be adjusted more accurately and conveniently, thereby adjusting the pressure of the tensioning wheel 50 on the transmission chain 31 to ensure that the transmission chain 31 is always in the expected tension state. When the transmission chain 31 is adjusted to a suitable tightness, the adjusting bolt 54 is tightened until the head of the adjusting bolt 54 hits the body of the silage machine, and then fixed by the nut 55.

[0056] In order to make the tension of the transmission chain 31 more stable, two tension springs 52 may be provided. The two tension springs 52 are respectively located on both sides of the tensioning wheel 50 so that the force on the tensioning wheel 50 is more balanced.

[0057] It should be noted that the body of the silage machine mentioned above specifically refers to the connecting seat 21 in this embodiment.

[0058] In order to make the rotation speed of the two hydraulic motors 20 intuitive, a rotation speed sensor 60 is also included for monitoring the rotation speed of the two hydraulic motors 20, ensuring that the silage machine feeding transmission device can promptly detect abnormal rotation speed during operation, and can more accurately control the synchronous movement of the two hydraulic motors 20, ensuring the coordinated operation between the feeding upper roller assembly and the feeding lower roller assembly as much as possible, thereby reducing material jamming or accumulation.

[0059] There may be two rotation speed sensors 60 , which may be located on the first mounting seat 22 and the second mounting seat 23 respectively. The rotation speed sensor 60 may obtain the rotation speed of the hydraulic motor 20 by detecting the output end rotation speed of the hydraulic motor 20 .

[0060] It is understandable that in other embodiments, the linkage assembly may also be a pulley and a transmission belt, and the two hydraulic motors are connected by the transmission belt, which generates less noise.

[0061] It can be understood that in other embodiments, when the distance between the two hydraulic motors is relatively close, gear transmission can be directly adopted to make the movement of the two hydraulic motors more synchronous.

[0062] It is understandable that in other embodiments, the two hydraulic motors may be respectively connected to the front upper roller and the front lower roller. When the two rollers on the same side are driven by the hydraulic motor, the synchronous movement between the two rollers can be better ensured, and the material jamming or accumulation caused by asynchronism can be further avoided.

[0063] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
