Description

Technical Field

[0001] This invention relates to the field of silage harvesting machinery, and in particular, to a feeding, chopping, attaching, and maintenance device. Furthermore, this invention also relates to a silage harvester including the aforementioned feeding, chopping, attaching, and maintenance device. Background Technology

[0002] A silage harvester mainly consists of a harvesting system, a feeding system, a chopping system, a crushing system, and a throwing system. It performs harvesting, feeding, chopping, grain crushing, and throwing operations on silage materials. Chopping is an intermediate step in the material handling process and is primarily achieved through the chopping system. The preceding systems are the harvesting system and the feeding system. While existing silage harvesters can easily and quickly engage and disengage the harvesting and feeding systems, engaging and disengaging the feeding and chopping systems is very difficult. This is because during silage harvester operation, the feeding and chopping systems must be stably and reliably engaged for normal operation. However, when it is necessary to inspect the rear roller of the feeding system or maintain the cutter roller of the chopping system, the feeding and chopping systems must be able to quickly disengage to complete the maintenance as soon as possible without affecting the silage harvesting process. In addition, since the scraper in the feeding system and the moving and fixed blades in the chopping system are the main working parts of the silage machine, they will be worn or damaged to varying degrees during operation. When the silage machine has been working for a period of time, the main working parts will be worn by the material or damaged by external factors, which will lead to a deterioration in the working quality of the silage machine, an increase in the energy consumption of the whole machine, and a decrease in the working effect. Therefore, it is necessary to inspect and maintain the main working parts of the silage machine from time to time according to the working effect of the silage machine.

[0003] Although Chinese utility model patent CN219741286U discloses a hook-and-unhooking device for a silage machine feeding system and a silage machine, which flexibly and quickly achieves the hooking and unhooking of the feeding system and the chopping system through the coordinated cooperation of the mounting frame, chopping system, feeding system, stretching component, and drive component, allowing for the separation of the feeding system and the chopping system during maintenance so that the feeding system can be removed first, and then the main working components can be repaired or replaced before finally hooking the feeding system back onto the chopping system; however, the above device requires the complete disconnection of the chopping system and the feeding system during maintenance in order to remove or install the feeding system. The feeding system is heavy and cannot be moved manually, requiring it to be moved to a specialized maintenance location with specialized machinery for maintenance. This high maintenance requirement significantly impacts maintenance efficiency. Furthermore, the assembly of the chopping system and the feeding system requires ensuring high assembly precision, which is difficult and further reduces maintenance efficiency. Summary of the Invention

[0004] This invention provides a feeding, chopping, and maintenance device and a silage harvester to solve the technical problems of high maintenance requirements and low maintenance efficiency when maintaining the main working components of the silage harvester.

[0005] According to one aspect of the present invention, a feeding and chopping hook-up maintenance device is provided, comprising a mounting frame, a tire assembly, a feeding system, a chopping system, a first connecting assembly, a second connecting assembly, a hook assembly, and a translation assembly. The tire assembly is mounted on the mounting frame, and the chopping system is mounted on the mounting frame and located between the tire assemblies. The lower end of the feeding system is detachably and rotatably connected to the lower end of the chopping system via the hook assembly. The translation assembly is horizontally disposed on the lower end of the chopping system and located below the feeding system. The translation assembly is used to roll with the feeding system after the feeding system is separated from the hook assembly, so that the feeding system can be translated relative to the chopping system. The first side of the upper end of the feeding system is connected to the first side of the upper end of the shredding system via the first connecting component. The second side of the upper end of the feeding system is connected to the second side of the upper end of the shredding system via the second connecting component. The first connecting component and the second connecting component cooperate to fix the feeding system relative to the shredding system, or to make the feeding system rotate vertically relative to the shredding system around the hook component, so that the feeding system and the shredding system are arranged in a V-shape in the vertical plane. Alternatively, the feeding system can be first moved a preset distance relative to the shredding system, and then the feeding system can be rotated horizontally relative to the shredding system around the first connecting component, so that the feeding system and the shredding system are arranged in a side-open layout in the horizontal plane.

[0006] As a further improvement to the above technical solution:

[0007] Furthermore, the first connecting assembly includes a guide shaft hinged to a first side portion of the upper end of the shredding system, an adapter hinged to a first side portion of the upper end of the feeding system, a connector hinged to the adapter and sleeved outside the guide shaft, a first locking pin for inserting into the guide shaft and the shredding system to fix the guide shaft relative to the shredding system, a second locking pin for inserting into the guide shaft and the connector to fix the guide shaft relative to the connector, and a third locking pin for inserting into the connector and the adapter to fix the connector relative to the adapter.

[0008] Furthermore, the connector includes a connecting plate, a socket hole that extends horizontally through the connecting plate and is sleeved on the outside of the guide shaft, a connecting shaft that is fixedly arranged radially on the connecting plate along the socket hole and hinged to the adapter, a fixing hole one that is vertically opened on the connecting plate and communicates with the socket hole for insertion and engagement with the second locking pin, and a fixing hole two that extends horizontally through the connecting plate and has its axis parallel to the axis of the connecting shaft for insertion and engagement with the third locking pin.

[0009] Furthermore, a first positioning hole, a second positioning hole, and a third positioning hole are sequentially provided on the guide shaft along the axial direction. The first positioning hole, the second positioning hole, and the third positioning hole are used to engage with the second locking pin after being coaxially arranged with the fixing hole.

[0010] Furthermore, when the second locking pin is engaged with the first fixing hole and the first positioning hole, the feeding system and the chopping system are in a hook-up working state. When the second locking pin is engaged with the first fixing hole and the second positioning hole, the feeding system and the chopping system are arranged sideways in the horizontal plane. When the second locking pin is engaged with the first fixing hole and the third positioning hole, the feeding system and the chopping system are arranged in a V-shape in the vertical plane.

[0011] Furthermore, the second connecting assembly includes a first hinge shaft hinged to the second side of the upper end of the shredding system, a second hinge shaft hinged to the second side of the upper end of the feeding system, a connecting screw threaded through the first hinge shaft and threaded to the second hinge shaft, and two locking nuts threaded to the connecting screw and respectively disposed at opposite ends of the first hinge shaft, wherein the thread direction on the second hinge shaft is opposite to the thread direction on the locking nuts.

[0012] Furthermore, the hook assembly includes a rotating shaft rotatably disposed on the lower end of the chopping system, a hook fixedly sleeved on the rotating shaft for engaging with the feeding system, and an adjusting member disposed on the lower end of the chopping system for supporting the hook upward and causing the hook to rotate or fall around the axis of the rotating shaft.

[0013] Furthermore, the translation component includes a guide rail that is arranged horizontally and fixedly disposed on the lower end of the shredding system.

[0014] Furthermore, the feeding system includes a feeding frame, a scraper disposed within the feeding frame, an ear plate fixedly disposed on a first side portion of the upper end of the feeding frame and hinged to a first connecting assembly, a mounting plate fixedly disposed on a second side portion of the upper end of the feeding frame and hinged to a second connecting assembly, a hook shaft disposed on the lower end of the feeding frame, and a roller fixedly sleeved on the hook shaft for rolling engagement with a translation assembly. The hook shaft and the hook assembly are detachably and rotatably connected.

[0015] Furthermore, the shredding system includes a shredding frame, a cutter roller disposed within the feeding frame, a hinge seat fixedly disposed on a first side portion of the upper end of the shredding frame and hinged to a first connecting assembly, and a mounting plate two fixedly disposed on a second side portion of the upper end of the shredding frame and hinged to a second connecting assembly.

[0016] According to another aspect of the invention, a silage harvester is also provided, which includes the above-described feeding, chopping, hooking, and maintenance device.

[0017] The present invention has the following beneficial effects:

[0018] The feeding and shredding attachment maintenance device of the present invention has a tire assembly and a shredding system mounted on a mounting frame. The first side of the upper end of the feeding system is connected to the first side of the upper end of the shredding system via a first connecting assembly. The second side of the upper end of the feeding system is connected to the second side of the upper end of the shredding system via a second connecting assembly. The lower end of the feeding system is attached to the shredding system via a hook assembly, ensuring contact and connection between the feeding system and the shredding system in all directions, providing reliable connection and high stability. In the attachment working state, the first and second connecting assemblies cooperate to fix the feeding system relative to the shredding system, ensuring the feeding and shredding... Structural stability during operation; During maintenance, the first and second connecting assemblies cooperate to allow the feeding system to rotate vertically relative to the shredding system around the hook assembly, so that the feeding system and the shredding system are arranged in a V-shape in the vertical plane. Then, the first and second connecting assemblies cooperate to fix the feeding system relative to the shredding system, ensuring structural stability during maintenance. This allows for the maintenance of the main working components within the feeding system and the shredding system. Since the shredding system is located between the tire assemblies, the maintenance difficulty of the main working components in the shredding system is increased during maintenance. This is addressed by separating the feeding system from the hook assembly to allow it to roll with the translation assembly. In conjunction with the first and second connecting components, the feeding system can roll and translate a preset distance relative to the chopping system on the translation component. At this point, the second side of the feeding system is suspended in the air, allowing it to be manually or mechanically driven to rotate horizontally relative to the chopping system around the first connecting component. This allows the feeding and chopping systems to be arranged sideways in the horizontal plane, increasing maintenance space and reducing maintenance difficulty, enabling maintenance of the main working components within both systems. In both maintenance states, since the connection between the feeding and chopping systems is not completely severed, there is no need for material handling. The mobile feeding system, during the process of resetting to the hook-up working state, can be assembled using the first connecting component as the assembly reference, resulting in low assembly difficulty, high assembly accuracy, and fast assembly speed. This solution, through the coordinated operation of the first connecting component, the second connecting component, the hook component, and the translation component, provides ample maintenance space for the main working components of both the feeding and chopping systems without completely disconnecting them. Compared to existing technologies, it has lower maintenance requirements, lower assembly difficulty for the feeding and chopping systems, higher assembly accuracy, higher maintenance efficiency, and strong practicality, making it suitable for widespread promotion and application.

Detailed Implementation

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0038] like Figures 1-8As shown, the feeding, chopping, and maintenance device of this embodiment includes a mounting frame 100, a tire assembly 200, a feeding system 300, a chopping system 400, a first connecting assembly 500, a second connecting assembly 600, a hook assembly 700, and a translation assembly 800. The tire assembly 200 is mounted on the mounting frame 100, and the chopping system 400 is mounted on the mounting frame 100 and located between the tire assemblies 200. The lower end of the feeding system 300 is detachably and rotatably connected to the lower end of the chopping system 400 via the hook assembly 700. The translation assembly 800 is horizontally positioned on the lower end of the chopping system 400 and below the feeding system 300. The translation assembly 800 is used to roll with the feeding system 300 after the feeding system 300 is separated from the hook assembly 700, so that the feeding system 300 can be translated relative to the chopping system 400. The first side of the upper end of the feeding system 300 is connected to the first side of the upper end of the chopping system 400 via the first connecting component 500. The second side of the upper end of the feeding system 300 is connected to the second side of the upper end of the chopping system 400 via the second connecting component 600. The first connecting component 500 and the second connecting component 600 cooperate to fix the feeding system 300 relative to the chopping system 400, or to make the feeding system 300 rotate vertically relative to the chopping system 400 around the hook component 700, so that the feeding system 300 and the chopping system 400 are arranged in a V-shape in the vertical plane. Alternatively, the feeding system 300 can be first moved a preset distance relative to the chopping system 400, and then the feeding system 300 can be rotated horizontally relative to the chopping system 400 around the first connecting component 500, so that the feeding system 300 and the chopping system 400 are arranged in a sideways layout in the horizontal plane.

[0039] It should be understood that the first or second perspective in different embodiments is not the same perspective.

[0040] like Figures 1-8As shown, specifically, in the feeding, shredding, and attachment maintenance device of the present invention, the tire assembly 200 and the shredding system 400 are arranged on the mounting frame 100. The first side of the upper end of the feeding system 300 is connected to the first side of the upper end of the shredding system 400 through the first connecting assembly 500, and the second side of the upper end of the feeding system 300 is connected to the second side of the upper end of the shredding system 400 through the second connecting assembly 600. The lower end of the feeding system 300 is attached to the shredding system 400 through the attachment hook assembly 700, so that the feeding system 300 and the shredding system 400 have contact and connection in all directions, ensuring reliable connection and high stability. In operation, the first connecting assembly 500 and the second connecting assembly 600 cooperate to fix the feeding system 300 relative to the chopping system 400, ensuring structural stability during feeding and chopping operations. During maintenance, the first connecting assembly 500 and the second connecting assembly 600 cooperate to rotate the feeding system 300 vertically relative to the chopping system 400 around the hook assembly 700, so that the feeding system 300 and the chopping system 400 are arranged in a V-shape in the vertical plane. Then, the first connecting assembly 500 and the second connecting assembly 600 cooperate to fix the feeding system 300 relative to the chopping system 400, ensuring structural stability during maintenance, thereby allowing for control of the feeding system. The main working components within system 300 and shredding system 400 are inspected and maintained. Since shredding system 400 is located between tire assemblies 200, the inspection process increases the difficulty of maintaining the main working components within shredding system 400. This is achieved by separating the feeding system 300 from the hook assembly 700 to allow it to roll and engage with the translation assembly 800. Then, through the first connecting assembly 500 and the second connecting assembly 600, the feeding system 300 can roll and translate a predetermined distance relative to the shredding system 400 on the translation assembly 800. At this time, the second side of the feeding system 300 is suspended in the air, allowing it to be driven manually or mechanically relative to the shredding system. The system 400 rotates horizontally around the first connecting component 500, thereby opening the feeding system 300 and the chopping system 400 laterally in the horizontal plane. This increases the maintenance space and reduces the difficulty of maintenance, allowing for the maintenance of the main working components within the feeding system 300 and the chopping system 400. In both maintenance states, since the connection between the feeding system 300 and the chopping system 400 is not completely disconnected, there is no need to move the feeding system 300. Furthermore, during the process of resetting to the hook-up working state, assembly can be performed using the first connecting component 500 as the assembly reference, resulting in low assembly difficulty, high assembly accuracy, and fast assembly speed.This solution, through the coordinated operation of the first connecting component 500, the second connecting component 600, the hook component 700, and the translation component 800, provides ample maintenance space for the main working components of the feeding system 300 and the chopping system 400 without completely detaching the connection between them. Compared to existing technologies, this solution has lower maintenance requirements, lower assembly difficulty and higher assembly precision for the feeding system 300 and the chopping system 400, higher maintenance efficiency, and strong practicality, making it suitable for widespread promotion and application.

[0041] It should be understood that the preset distance can be adaptively set according to maintenance requirements.

[0042] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it should be understood that vertical rotation refers to rotation in a vertical plane, while horizontal rotation refers to rotation in a horizontal plane.

[0043] Optionally, the feeding and chopping attachment maintenance device also includes a traction rope or an auxiliary support. When the feeding system 300 and the chopping system 400 are arranged sideways in the horizontal plane, the second side of the feeding system 300 is still suspended and can rotate horizontally relative to the chopping system 400. The feeding system 300 is fixed by auxiliary tools such as traction ropes or auxiliary supports to prevent it from shaking randomly, thereby improving the structural stability during maintenance.

[0044] like Figures 5-8 As shown, it should be understood that due to the compact space of the whole machine, the feeding system 300 is difficult to open to the side when it is in normal engagement position due to the limitations of the tire assembly 200 and the mounting bracket. Or the angle of the side opening is limited and not enough to provide sufficient maintenance space for maintenance personnel. Therefore, it is necessary to first push and move the preset distance before the side opening action is performed.

[0045] like Figures 9-12 As shown, in this embodiment, the first connecting assembly 500 includes a guide shaft 510 hinged to a first side portion of the upper end of the chopping system 400, an adapter 520 hinged to a first side portion of the upper end of the feeding system 300, a connector 530 hinged to the adapter 520 and sleeved outside the guide shaft 510, a first locking pin 540 for inserting and cooperating with the guide shaft 510 and the chopping system 400 to fix the guide shaft 510 relative to the chopping system 400, a second locking pin 550 for inserting and cooperating with the guide shaft 510 and the connector 530 to fix the guide shaft 510 relative to the connector 530, and a third locking pin 560 for inserting and cooperating with the connector 530 and the adapter 520 to fix the connector 530 relative to the adapter 520.

[0046] like Figures 9-12 As shown, specifically, the guide shaft 510 is hinged to the first side of the upper end of the shredding system 400, and the connecting piece 530 is hinged to the adapter piece 520 and sleeved on the guide shaft 510, so that the feeding system 300 can rotate vertically relative to the shredding system 400 around the hook assembly 700, thereby realizing the conversion from the hook working state to the V-shaped maintenance state; the adapter piece 520 is hinged to the first side of the upper end of the feeding system 300, so that the feeding system 300 can rotate vertically relative to the shredding system 400 around the hook assembly 700. The 400 rotates horizontally around the adapter 520 to switch between the hook-on working state and the side-opening maintenance state. In either the hook-on working state or the side-opening maintenance state, the first locking pin 540 engages with the guide shaft 510 and the shredding system 400 to fix the guide shaft 510 relative to the shredding system 400. The second locking pin 550 engages with the guide shaft 510 and the connector 530 to fix the guide shaft 510 relative to the connector 530. The third locking pin 560... Connector 530 and adapter 520 are plugged into each other to fix connector 530 relative to adapter 520, ensuring structural stability in this state. In the V-shaped maintenance state, first locking pin 540 is plugged into guide shaft 510 and shredding system 400 to fix guide shaft 510 relative to shredding system 400, and second locking pin 550 is plugged into guide shaft 510 and connector 530 to fix guide shaft 510 relative to connector 530, ensuring structural stability in this state. When feeding system 300 translates relative to shredding system 400, first locking pin 540 is plugged into guide shaft 510 and shredding system 400 to fix guide shaft 510 relative to shredding system 400, thereby guiding the translation. In each state and during state transitions, the stability of the entire structure is ensured by first locking pin 540, second locking pin 550, and third locking pin 560, reducing safety risks during maintenance. Optionally, the guide shaft 510 is provided with L-shaped connecting blocks, which are hinged to the chopping system 400.

[0047] like Figure 11As shown, in this embodiment, the connector 530 includes a connecting plate 531, a socket 532 extending horizontally through the connecting plate 531 and sleeved on the guide shaft 510, a connecting shaft 533 radially fixed on the connecting plate 531 along the socket 532 and hinged to the adapter 520, a first fixing hole 534 vertically formed on the connecting plate 531 and communicating with the socket 532 for insertion and engagement with the second locking pin 550, and a second fixing hole 535 extending horizontally through the connecting plate 531 and with its axis parallel to the axis of the connecting shaft 533 for insertion and engagement with the third locking pin 560. Specifically, the connecting plate 531 is sleeved on the guide shaft 510 through the socket 532, hinged to the adapter 520 through the connecting shaft 533, inserted and engaged with the second locking pin 550 through the first fixing hole 534, and inserted and engaged with the third locking pin 560 through the second fixing hole 535.

[0048] like Figure 10 As shown, in this embodiment, the guide shaft 510 is provided with a first positioning hole 511, a second positioning hole 512, and a third positioning hole 513 sequentially along the axial direction. The first positioning hole 511, the second positioning hole 512, and the third positioning hole 513 are used to engage with the second locking pin 550 after being coaxially arranged with the first fixing hole 534. When the second locking pin 550 is engaged with the first fixing hole 534 and the first positioning hole 511, the feeding system 300 and the chopping system 400 are in a hook-up working state. When the second locking pin 550 is engaged with the first fixing hole 534 and the second positioning hole 512, the feeding system 300 and the chopping system 400 are arranged sideways in the horizontal plane. When the second locking pin 550 is engaged with the first fixing hole 534 and the third positioning hole 513, the feeding system 300 and the chopping system 400 are arranged in a V-shape in the vertical plane.

[0049] like Figure 10 As shown, specifically, the second locking pin 550 is inserted sequentially into the fixing hole 534 and the first positioning hole 511 to ensure the structural stability of the feeding system 300 and the shredding system 400 in the connected working state; the second locking pin 550 is inserted sequentially into the fixing hole 534 and the second positioning hole 512 to ensure the structural stability of the feeding system 300 and the shredding system 400 in the side-open maintenance state; the second locking pin 550 is inserted sequentially into the fixing hole 534 and the third positioning hole 513 to ensure the structural stability of the feeding system 300 and the shredding system 400 in the V-shaped maintenance state.

[0050] It should be understood that the above-mentioned locking structure facilitates state switching and is convenient and quick to operate.

[0051] like Figure 13As shown, in this embodiment, the second connecting assembly 600 includes a first hinge shaft 610 hinged to the second side of the upper end of the chopping system 400, a second hinge shaft 620 hinged to the second side of the upper end of the feeding system 300, a connecting screw 630 passing through the first hinge shaft 610 and threadedly connected to the second hinge shaft 620, and two locking nuts 640 threadedly connected to the connecting screw 630 and respectively arranged at opposite ends of the first hinge shaft 610. The thread direction on the second hinge shaft 620 is opposite to the thread direction on the locking nuts 640. Specifically, since the thread direction on the second hinge shaft 620 is opposite to that on the locking nut 640, rotating the connecting screw 630 can move the second hinge shaft 620 away from or closer to the first hinge shaft 610, thereby moving the feeding system 300 away from or closer to the chopping system 400. This allows for the switching between the hanging working state and the maintenance state. When switching from the hanging working state to the side-open maintenance state, separating the connecting screw 630 from the second hinge shaft 620 allows the feeding system 300 to be suspended in the air, enabling it to rotate horizontally relative to the chopping system 400 around the first connecting assembly 500. Optionally, the end of the connecting screw 630 is provided with a handle for easy rotation. Optionally, the end of the connecting screw 630 is provided with a drive assembly, which is a motor, driving the connecting screw 630 to rotate.

[0052] like Figure 14 As shown, in this embodiment, the hook assembly 700 includes a rotating shaft 710 rotatably disposed on the lower end of the chopping system 400, a hook 720 fixedly sleeved on the rotating shaft 710 for engaging with the feeding system 300, and an adjusting member disposed on the lower end of the chopping system 400 for upwardly supporting the hook 720 and causing the hook 720 to rotate upwards or downwards around the axis of the rotating shaft 710. Specifically, by the adjusting member upwardly supporting the hook 720, the feeding system 300 can be hooked onto the chopping system 400; by the adjusting member causing the hook 720 to rotate upwards around the axis of the rotating shaft 710, the feeding system 300 engages with the hook 720, and then the adjusting member upwardly supports the hook 720; or by the adjusting member causing the hook 720 to fall downwards around the axis of the rotating shaft 710, the hook 720 is separated from the feeding system 300, at which time the feeding system 300 and the translation assembly 800 are in rolling engagement. Optionally, the adjusting component includes an adjusting part 730 fixedly disposed on the lower end of the chopping system 400 and an adjusting bolt 740 for pushing the hook 720 upward by passing through the adjusting part 730 vertically and being threadedly connected to the adjusting part 730. The hook 720 is supported by the adjusting bolt 740, and the hook 720 is rotated or lowered around the axis of the rotating shaft 710 by rotating the adjusting bolt 740.

[0053] like Figure 2As shown, in this embodiment, the translation component 800 includes a guide rail arranged horizontally and fixedly disposed on the lower end of the chopping system 400. Specifically, the guide rail rolls with the lower end of the feeding system 300, causing the feeding system 300 to roll and translate a preset distance relative to the chopping system 400 along the guide rail. It should be understood that the preset distance depends on the length of the guide rail.

[0054] like Figure 8 and Figure 13 As shown, in this embodiment, the feeding system 300 includes a feeding frame 310, a scraper 360 disposed within the feeding frame 310, an ear plate 320 fixedly disposed on a first side portion of the upper end of the feeding frame 310 and hinged to a first connecting assembly 500, a mounting plate 330 fixedly disposed on a second side portion of the upper end of the feeding frame 310 and hinged to a second connecting assembly 600, a hook shaft 340 disposed on the lower end of the feeding frame 310, and a roller 350 fixedly sleeved on the hook shaft 340 for rolling cooperation with the translation assembly 800. The hook shaft 340 and the hook assembly 700 are detachably and rotatably connected. Specifically, a scraper 360, ear plate 320, mounting plate 330, hook shaft 340, and roller 350 are mounted on the feeding frame 310 to allow for regular inspection, maintenance, and upkeep of the scraper 360. The ear plate 320 is hinged to the first connecting assembly 500, and the mounting plate 330 is hinged to the second connecting assembly 600. The hook shaft 340 is detachably and rotatably connected to the hook assembly 700 to ensure structural stability after the feeding system 300 and the chopping system 400 are connected, and to allow for state transitions. After the hook shaft 340 is separated from the hook assembly 700, the roller 350 engages with the translation assembly 800 in a rolling manner, allowing the feeding system 300 to translate relative to the chopping system 400. It should be understood that the scraper 360 is the main working component in the feeding system 300. Optionally, the adapter 520 includes an adapter block 522 and an adapter shaft 521 passing through the adapter block 522 and the ear plate 320 for rotating the adapter block 522 relative to the ear plate 320. The adapter block 522 has a fixing hole 523 that is threadedly connected to the third locking pin 560.

[0055] like Figure 12 As shown, optionally, the adapter block 522 has a second hinge hole 524 that is hinged to the connecting shaft 533. Optionally, the adapter block 522 has a third hinge hole 525 that is hinged to the adapter shaft 521.

[0056] like Figure 8 , Figure 13 and Figure 14As shown, in this embodiment, the shredding system 400 includes a shredding frame 410, a cutter roller arranged within the feeding frame 310, a hinge seat 420 fixedly arranged on a first side portion of the upper end of the shredding frame 410 and hinged to a first connecting assembly 500, and a mounting plate 430 fixedly arranged on a second side portion of the upper end of the shredding frame 410 and hinged to a second connecting assembly 600. Specifically, the cutter roller, hinge seat 420, and mounting plate are mounted on the shredding frame 410 for periodic inspection, maintenance, and upkeep of the cutter roller. The hinge seat 420 is hinged to the first connecting assembly 500, and the mounting plate 430 is hinged to the second connecting assembly 600 to ensure the structural stability of the feeding system 300 and the shredding system 400 after connection, and to allow for state transitions. It should be understood that the cutter roller is the main working component in the shredding system 400. Optionally, the cutter roller includes a fixed blade 450 and a moving blade 440. Optionally, the shredding frame 410 has a first insertion hole 514 that engages with the first locking pin 540, and the connecting block has a second insertion hole corresponding to the first insertion hole 514. Optionally, the connecting block has a first hinge hole 515 that hinges with the hinge seat 420.

[0057] The silage harvester of this embodiment includes the aforementioned feeding, chopping, and maintenance device. Specifically, by employing the aforementioned feeding, chopping, and maintenance device in the silage harvester, sufficient maintenance space is provided to inspect and maintain the main working components of the feeding system 300 and the chopping system 400 without completely disconnecting the feeding system 300 and the chopping system 400. The maintenance requirements are low, the assembly difficulty of the feeding system 300 and the chopping system 400 is low, the assembly accuracy is high, the maintenance efficiency is high, and the device is highly practical, making it suitable for widespread promotion and application.

[0058] In one embodiment, the silage machine includes the following states:

[0059] like Figure 1 and Figure 2 As shown, in the working state of the silage harvester, the feeding system 300 is attached to the chopping system 400, and the two do not move relative to each other. At this time, the attachment shaft 340 of the feeding system 300 and the hook 720 of the attachment hook assembly 700 are engaged under the action of the adjusting bolt 740. The first side of the upper end of the feeding system 300 is connected to the first side of the upper end of the chopping system 400 through the first connecting assembly 500. At this time, the first locking pin 540 is inserted into the second insertion hole and the first insertion hole 514 in sequence, the second locking pin 550 is inserted into the first fixing hole 534 and the first positioning hole 511 in sequence, and the third locking pin 560 is inserted into the second fixing hole 535 and the third fixing hole 523 in sequence.

[0060] like Figure 3 and Figure 4As shown, when the silage harvester's performance deteriorates and cleaning and maintenance are required, the first locking pin 540 is pulled out from the first insertion hole 514 and the second insertion hole, releasing the restriction on the rotation of the guide shaft 510; the second locking pin 550 is pulled out from the first fixing hole 534 and the first positioning hole 511, releasing the restriction on the sliding of the connecting piece 530 relative to the guide shaft 510; and the third locking pin 560 is pulled out from the second fixing hole 535 and the third fixing hole 523, releasing the restriction on the rotation of the connecting piece 530 relative to the adapter 520. Then, the connecting screw 6 is rotated. 30, so that the feeding system 300 rotates around the axis of the connecting shaft 340 in a direction away from the chopping system 400, realizing a V-shaped opening action, until the connecting piece 530 slides relative to the guide shaft 510 to the third positioning hole 513, at which point the second locking pin 550 is sequentially inserted into the first fixing hole 534 and the third positioning hole 513. At this time, the feeding system 300 is in a V-shaped maintenance state relative to the chopping system 400, which facilitates maintenance personnel to inspect and maintain the scraper 360 in the feeding system 300 and the cutter roller in the chopping system 400. After maintenance is completed, the second locking pin 550 is pulled out from the first fixing hole 534 and the third positioning hole 513, and after returning to the initial position, the first locking pin 540, the second locking pin 550, and the third locking pin 560 are inserted respectively.

[0061] like Figure 5 and Figure 6 As shown, when the working effect of the silage harvester deteriorates and a larger maintenance space is required, the rotating adjusting bolt 740 moves downward relative to the adjusting part 730, so that the hook 720 rotates downward and separates from the hanging shaft 340, thereby allowing the roller 350 to slide into the guide rail. At this time, the second locking pin 550 is pulled out from the fixing hole 534 and the first positioning hole 511, releasing the restriction on the sliding of the connecting piece 530 relative to the guide shaft 510. Then, the connecting screw 630 is rotated so that the feeding system 300 moves a preset distance relative to the chopping system 400 from the guide roller to the flat push. At this time, the roller 350 separates from the guide rail, and the fixing hole 534 and the second positioning hole 512 are coaxially arranged. Therefore, the second locking pin 550 is inserted into the fixing hole 534 and the second positioning hole 512 in sequence to complete the flat push opening action.

[0062] like Figure 7 and Figure 8As shown, after the above actions are completed, remove the locking nut on the end of the connecting screw 630 near the first hinge shaft 610 facing away from the second hinge shaft 620. Then rotate the connecting screw 630 to separate it from the first hinge shaft 610. At this time, the second connecting assembly 600 no longer connects the upper ends of the feeding system 300 and the chopping system 400. The feeding system 300 is suspended in the air. Then pull the connecting screw 630 to make the feeding system 300 rotate horizontally relative to the chopping system 400 around the adapter shaft 521 to perform a side opening action until the feeding system 300 is at a suitable angle relative to the chopping system 400. At this time, fix the feeding system 300 with auxiliary tools such as traction ropes or auxiliary supports to prevent it from shaking. Then the scraper 360 in the feeding system 300 and the cutter roller in the chopping system 400 can be inspected and maintained.

[0063] like Figure 1 and Figure 2 As shown, after maintenance, the feeding system 300 is pushed to rotate horizontally relative to the chopping system 400 around the adapter shaft 521 until the axis of the connecting screw 630 is coaxial with the axis of the hinge hole on the first hinge shaft 610. Then, the connecting screw 630 is rotated to hinge the connecting screw 630 with the first connecting shaft 533. Then, the previously removed locking nut is screwed on to clamp the shaft. The second locking pin 550 is pulled out from the first fixing hole 534 and the second positioning hole 512 to rotate the connecting screw 630, causing the feeding system 300 to move closer to the chopping system 400. The roller 350 and the guide rail roll together until the first fixing hole 534 and the first positioning hole 511 are coaxial. Then, the second locking hole is inserted into the first fixing hole 534 and the first positioning hole 511 in sequence, so that the feeding system 300 and the chopping system 400 return to the connected working state.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
