Description

Technical Field

[0001] This utility model relates to the field of silage harvesters, and in particular to a side-opening structure for a silage harvester. Background Technology

[0002] Currently, the feeding assembly and chopping assembly in a forage harvester are connected by hooks and a locking device. The hooks are installed on both sides of the chopping assembly, pressing the feeding assembly onto it. The inner tube of the feeding assembly is installed inside the locking device. To observe the internal components of the forage harvester, the hooks on both sides are loosened, while the locking device remains in place. The feed assembly is then lifted by the cutter cylinder, causing it to rotate around the axis of the locking device, thus achieving a "V"-shaped opening between the feeding assembly and the chopping assembly. However, this "V"-shaped opening method is limited by the lifting height of the cutter cylinder, resulting in a small open space that makes it difficult to directly observe the internal components of the forage harvester, and hinders the replacement and repair of parts. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a side-opening structure for a silage harvester to solve the above-mentioned problem.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A side-opening structure for a silage harvester includes: a lower fixing mechanism, an upper fixing mechanism, and a limiting rod. The lower fixing mechanism and the upper fixing mechanism are fixedly installed on the chopping assembly and the feeding assembly respectively. The lower fixing mechanism is engaged or disengaged from the feeding assembly, and the upper fixing mechanism is inserted or disengaged from the chopping assembly. One end of the limiting rod is hinged to the feeding assembly, and the other end is inserted or disengaged from the chopping assembly. One side of the feeding assembly is hinged to one side of the chopping assembly.

[0005] The beneficial effects of this utility model are as follows: one side of the feeding assembly is hinged to one side of the chopping assembly, and in conjunction with the lower and upper fixing mechanisms, it is beneficial to lock and unlock the feeding assembly and the chopping assembly. The limiting rod is inserted into different positions on the chopping assembly through its other end, which is beneficial to limit the feeding assembly and the chopping assembly in the unlocked side open or locked closed state, thereby fixing the relative position between the feeding assembly and the chopping assembly in the unlocked side open or locked closed state. It is also beneficial to adjust the size of the space between the feeding assembly and the chopping assembly in the unlocked side open state. Compared with the "V" type opening method in the prior art, this utility model is beneficial to make the space after the feeding assembly and the chopping assembly are unlocked and opened, so as to more intuitively observe the internal parts of the silage machine, thereby facilitating the replacement of parts and facilitating maintenance.

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

[0007] Furthermore, the lower fixing mechanism includes: a fixed locking hook, a movable locking hook, a connecting rod, and a locking hook fixing assembly; the fixed locking hook is fixedly installed on the chopping assembly, one end of the connecting rod is rotatably connected to the fixed locking hook, the movable locking hook is fixedly sleeved on the connecting rod, the locking hook fixing assembly is fixedly installed on the fixed locking hook and abuts against the movable locking hook, and an inner round tube is fixedly installed on the feeding assembly, the inner round tube engaging or disengaging with the fixed locking hook and the movable locking hook.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the locking hook fixing assembly is conducive to driving the movable locking hook and the connecting rod to rotate, thereby cooperating with the fixed locking hook to realize the snapping or separation of the inner round tube, and thus realizing the unlocking side opening or locking closure of the feeding assembly and the chopping assembly.

[0009] Furthermore, both the fixed locking hook and the movable locking hook have arc-shaped grooves on their side walls. The movable locking hook rotates until the arc-shaped grooves of the fixed locking hook and the movable locking hook surround the inner tube, or rotates until the arc-shaped grooves of the fixed locking hook and the movable locking hook loosen the inner tube.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the arc-shaped groove helps the inner round tube to better engage with the fixed locking hook and the movable locking hook.

[0011] Furthermore, the locking hook fixing assembly includes: a fixed housing, a rotating shaft, and an adjusting bolt; the fixed housing is a U-shaped plate structure, with its open end fixedly installed on the side wall of the fixed locking hook; the rotating shaft is rotatably installed inside the fixed housing; the adjusting bolt is threaded through the side wall of the rotating shaft, with one end abutting against the movable locking hook and used to drive the movable locking hook to rotate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the adjusting bolt, through its threaded connection with the rotating shaft, facilitates the adjustment of the length of the part extending from the rotating shaft, thereby driving the movable locking hook to rotate and thus achieving engagement or disengagement with the inner tube.

[0013] Furthermore, the upper fixing mechanism includes: a driving component, a first transmission component, and a second transmission component; the chopping assembly is provided with a first through hole, the feeding assembly is provided with a second through hole, the driving component is fixedly installed on the feeding assembly, one end of which is hinged to the top end of the first transmission component, the second transmission component slides through the second through hole, one end of which is hinged to the bottom end of the first transmission component, and the other end of which is inserted into or separated from the first through hole.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the drive component is conducive to driving the displacement of the first transmission component and the second transmission component, thereby enabling the second transmission component to be inserted into or separated from the shredding assembly, and thus realizing the unlocking side opening or locking closure of the feeding assembly and the shredding assembly.

[0015] Furthermore, the drive assembly includes: a fixed plate, a drive sleeve, a handle, and a drive rod; the fixed plate is fixedly mounted on the feeding assembly, the drive sleeve rotatably passes through the fixed plate, one end of which is fixedly connected to the handle, and the other end of which is threaded onto one end of the drive rod, and the other end of the drive rod is hinged to the top end of the first transmission assembly.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the handle facilitates the rotation of the drive sleeve on the fixed plate, thereby enabling the drive rod to extend and retract along the drive sleeve through the threaded connection between the drive rod and the drive sleeve, thus realizing the rotation of the first transmission component.

[0017] Furthermore, the first transmission assembly includes: a first rotating plate, a rotating rod, a limiting housing, and two second rotating plates; one side of the first rotating plate is hinged to the drive assembly, and the other side is fixedly connected to the top end of the rotating rod; the two second rotating plates are spaced apart vertically, with the middle fixedly sleeved on the lower end of the rotating rod; the limiting housing is mounted on the feeding assembly; the rotating rod rotatably passes through the limiting housing; and one end of the second transmission assembly is hinged to the end between the two second rotating plates.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the first rotating plate and the rotating rod facilitate the transmission of power in the drive assembly to the two second rotating plates, thereby driving the second transmission assembly to rotate relative to the second rotating plate, and thus driving the second transmission assembly to engage or disengage from the shredding assembly.

[0019] Furthermore, the second transmission component includes: a first sliding pin and a second sliding pin; one end of the first sliding pin is hinged to one side of the bottom end of the first transmission component, and the other end is hinged to one end of the second sliding pin; the second sliding pin passes through the second through hole, and the other end is inserted into or separated from the first through hole.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the hinge between the first sliding pin and the second sliding pin is conducive to the second sliding pin being inserted into or separated from the shredding assembly under the power transmitted by the first transmission component, thereby realizing the unlocking side opening or locking closure of the feeding assembly and the shredding assembly.

[0021] Furthermore, it also includes a reinforcing plate. A first arm is fixedly installed on the upper end of one side of the feeding assembly and the upper end of one side of the chopping assembly. A second arm is fixedly installed on the lower end of one side of the feeding assembly and the lower end of one side of the chopping assembly. The first arm on the feeding assembly is hinged to the first arm on the chopping assembly, and the second arm on the feeding assembly is hinged to the second arm on the chopping assembly. The top and bottom ends of the reinforcing plate are fixedly connected to the first arm and the second arm respectively.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the first arm and the second arm facilitate the hinge connection between the feeding assembly and the shredding assembly, and the reinforcing plate helps to enhance the connection strength between the feeding assembly and the shredding assembly when the side is unlocked.

[0023] Furthermore, it also includes an indicator mechanism, which includes an indicator rod, a pin, and an indicator hole. The indicator hole is formed on the side wall of the chopping assembly, and the top end of the indicator rod is hinged to the side wall of the chopping assembly via the pin.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the pin shaft facilitates the rotation of the indicator rod with the attitude adjustment of the chopping assembly. When the bottom end of the indicator rod points to the indicator hole, it means that the feeding assembly and the chopping assembly are in an unlocked side-opening position that will not interfere with other functional structures of the silage machine. At this time, the side-opening can be unlocked. Attached Figure Description

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 5 As shown, this embodiment provides a side-opening structure for a silage harvester, including: a lower fixing mechanism 1, an upper fixing mechanism 2, and a limiting rod 3. The lower fixing mechanism 1 and the upper fixing mechanism 2 are fixedly installed on the chopping assembly 7 and the feeding assembly 6 respectively. The lower fixing mechanism 1 is engaged or disengaged from the feeding assembly 6, and the upper fixing mechanism 2 is inserted into or disengaged from the chopping assembly 7. One end of the limiting rod 3 is hinged to the feeding assembly 6, and the other end is inserted into or disengaged from the chopping assembly 7. One side of the feeding assembly 6 is hinged to one side of the chopping assembly 7.

[0029] It should be noted that in this embodiment, the chopping assembly 7 is provided with a plurality of insertion holes for fitting and connecting with the other end of the limiting rod 3, thereby adjusting the size of the space when the feeding assembly 6 and the chopping assembly 7 are unlocked by connecting the other end of the limiting rod 3 to different insertion holes; The prior art technique of connecting the feeding assembly 6 and the chopping assembly 7 via hooks and locking devices is essentially equivalent to the lower fixing mechanism 1 and the inner tube 11 in this application. That is, after the lower fixing mechanism 1 clamps the inner tube 11, the V-shaped opening of the feeding assembly 6 and the chopping assembly 7 is achieved through the rotational connection between the lower fixing mechanism 1 and the inner tube 11. The difference lies in that this V-shaped opening method is limited by the lifting distance of the cutting table cylinder and also by the structural interference between the lower ends of the feeding assembly 6 and the chopping assembly 7. Ultimately, this results in a smaller maximum side opening angle for the feeding assembly 6 and the chopping assembly 7 after V-shaped opening in the prior art. Visual observation of the internal components of the silage harvester reveals difficulties in replacing and repairing them. This application replaces the hinge between the feeding assembly 6 and the chopping assembly 7 with the sides of both assemblies, eliminating structural interference between them. Furthermore, the previously hinged lower fixing mechanism 1 and inner tube 11 are adjusted to be either separated or engaged, achieving a fixing function in this application. In other words, while the lower fixing mechanism 1 and inner tube 11 in the prior art functioned as the hinge between the feeding assembly 6 and the chopping assembly 7, in this application they function as the means to fix and separate the feeding assembly 6 and the chopping assembly 7.

[0030] The beneficial effects of this utility model are as follows: one side of the feeding assembly is hinged to one side of the chopping assembly, and in conjunction with the lower and upper fixing mechanisms, it is beneficial to lock and unlock the feeding assembly and the chopping assembly. The limiting rod is inserted into different positions on the chopping assembly through its other end, which is beneficial to limit the feeding assembly and the chopping assembly in the unlocked side open or locked closed state, thereby fixing the relative position between the feeding assembly and the chopping assembly in the unlocked side open or locked closed state. It is also beneficial to adjust the size of the space between the feeding assembly and the chopping assembly in the unlocked side open state. Compared with the "V" type opening method in the prior art, this utility model is beneficial to make the space after the feeding assembly and the chopping assembly are unlocked and opened, so as to more intuitively observe the internal parts of the silage machine, thereby facilitating the replacement of parts and facilitating maintenance.

[0031] Preferred, such as Figure 1 and Figure 4 As shown, the lower fixing mechanism 1 includes: a fixed locking hook 12, a movable locking hook 13, a connecting rod 14, and a locking hook fixing assembly 15; the fixed locking hook 12 is fixedly installed on the chopping assembly 7, one end of the connecting rod 14 is rotatably connected to the fixed locking hook 12, the movable locking hook 13 is fixedly sleeved on the connecting rod 14, the locking hook fixing assembly 15 is fixedly installed on the fixed locking hook 12 and abuts against the movable locking hook 13, and an inner round tube 11 is fixedly installed on the feeding assembly 6, the inner round tube 11 being engaged or disengaged from the fixed locking hook 12 and the movable locking hook 13.

[0032] It should be noted that in this embodiment, there are two fixed locking hooks 12 and two movable locking hooks 13. The two fixed locking hooks 12 are spaced apart and fixedly installed at the lower end of the chopping assembly 7. The two ends of the connecting rod 14 are rotatably connected to the two fixed locking hooks 12 respectively. The two movable locking hooks 13 are spaced apart and fixedly sleeved on the connecting rod 14. The movable locking hooks 13 are disposed between the two fixed locking hooks 12. The locking hook fixing assembly 15 is fixedly installed on one of the fixed locking hooks 12 and abuts against one of the movable locking hooks 13.

[0033] The advantages of adopting the above preferred solution are: the locking hook fixing component is conducive to driving the movable locking hook and the connecting rod to rotate, thereby cooperating with the fixed locking hook to realize the snapping or separation of the inner round tube, and thus realizing the unlocking side opening or locking closure of the feeding assembly and the chopping assembly.

[0034] Preferred, such as Figure 4 As shown, both the fixed locking hook 12 and the movable locking hook 13 have arc-shaped grooves on their side walls. The movable locking hook 13 rotates until the arc-shaped grooves of the fixed locking hook 12 and the movable locking hook 13 enclose the inner tube 11, or rotates until the arc-shaped grooves of the fixed locking hook 12 and the movable locking hook 13 release the inner tube 11.

[0035] The advantages of adopting the above preferred solution are: the arc-shaped groove helps the inner tube to better engage with the fixed locking hook and the movable locking hook.

[0036] Preferred, such as Figure 4 As shown, the locking hook fixing assembly 15 includes: a fixed housing 151, a rotating shaft 152, and an adjusting bolt 153; the fixed housing 151 is a U-shaped plate structure, with its open end fixedly installed on the side wall of the fixed locking hook 12; the rotating shaft 152 is rotatably installed inside the fixed housing 151; the adjusting bolt 153 is threaded through the side wall of the rotating shaft 152, with one end abutting against the movable locking hook 13 and used to drive the movable locking hook 13 to rotate.

[0037] The advantages of adopting the above preferred solution are: the adjusting bolt, through its threaded connection with the rotating shaft, facilitates the adjustment of the length of the part extending from the rotating shaft, thereby driving the movable locking hook to rotate, and thus achieving engagement or disengagement with the inner tube.

[0038] Preferred, such as Figure 3As shown, the upper fixing mechanism 2 includes: a driving component 21, a first transmission component 24, and a second transmission component 25; the chopping assembly 7 is provided with a first through hole, the feeding assembly 6 is provided with a second through hole, the driving component 21 is fixedly installed on the feeding assembly 6, one end of which is hinged to the top end of the first transmission component 24, the second transmission component 25 slides through the second through hole, one end of which is hinged to the bottom end of the first transmission component 24, and the other end of which is inserted into or separated from the first through hole.

[0039] It should be noted that in this embodiment, the first transmission component 24 is mounted on the feeding assembly 6; Two first locking plates 22 are fixedly installed at intervals on the chopping assembly 7, and two second locking plates 23 are fixedly installed at intervals on the feeding assembly 6. The first through hole is a through hole provided on the first locking plate 22, and the second through hole is a through hole provided on the second locking plate 23. There are two second transmission components 25. The two second transmission components 25 pass through the second through holes on the two second locking plates 23 one by one. One end of each component is hinged to the two sides of the bottom end of the first transmission component 24, and the other end is inserted into or separated from the first through hole on the first locking plate 22.

[0040] The advantages of adopting the above preferred solution are: the drive component is conducive to driving the displacement of the first transmission component and the second transmission component, thereby enabling the second transmission component to be inserted into or separated from the shredding assembly, and thus realizing the unlocking side opening or locking closure of the feeding assembly and the shredding assembly.

[0041] Preferred, such as Figure 3 As shown, the drive assembly 21 includes: a fixed plate 211, a drive sleeve 212, a handle 213, and a drive rod 214; the fixed plate 211 is fixedly installed on the feeding assembly 6, the drive sleeve 212 rotatably passes through the fixed plate 211, one end of which is fixedly connected to the handle 213, and the other end of which is threaded onto one end of the drive rod 214, and the other end of the drive rod 214 is hinged to the top end of the first transmission assembly 24.

[0042] It should be noted that in this embodiment, the fact that the driving sleeve 212 can rotatably pass through the fixing plate 211 means that the fixing plate 211 limits the axial displacement of the driving sleeve 212, but does not limit its circumferential displacement. That is, the driving sleeve 212 can rotate relative to the fixing plate 211, but cannot move along the length direction of the driving sleeve 212.

[0043] The advantages of adopting the above preferred solution are: the handle facilitates the rotation of the drive sleeve on the fixed plate, thereby enabling the drive rod to extend and retract along the drive sleeve through the threaded connection between the drive rod and the drive sleeve, thus realizing the rotation of the first transmission component.

[0044] Preferred, such as Figure 3 As shown, the first transmission assembly 24 includes: a first rotating plate 241, a rotating rod 242, a limiting housing 243, and two second rotating plates 244; one side of the first rotating plate 241 is hinged to the drive assembly 21, and the other side is fixedly connected to the top end of the rotating rod 242; the two second rotating plates 244 are arranged vertically at intervals, with the middle fixedly sleeved on the lower end of the rotating rod 242; the limiting housing 243 is mounted on the feeding assembly 6; the rotating rod 242 rotatably passes through the limiting housing 243; and one end of the second transmission assembly 25 is hinged to the end between the two second rotating plates 244.

[0045] It should be noted that in this embodiment, one side of the first rotating plate 241 is hinged to the other end of the drive rod 214. One end of each of the two second transmission components 25 is disposed at one end between the two ends of the two second rotating plates 244 and is hinged to the two second rotating plates 244.

[0046] The advantages of adopting the above preferred solution are: the first rotating plate and the rotating rod facilitate the transmission of power in the drive assembly to the two second rotating plates, thereby driving the second transmission assembly to rotate relative to the second rotating plate, and thus driving the second transmission assembly to engage or disengage from the shredding assembly.

[0047] Preferred, such as Figure 3 As shown, the second transmission assembly 25 includes: a first sliding pin 251 and a second sliding pin 252; one end of the first sliding pin 251 is hinged to one side of the bottom end of the first transmission assembly 24, and the other end is hinged to one end of the second sliding pin 252; the second sliding pin 252 passes through the second through hole, and the other end is inserted into or separated from the first through hole.

[0048] It should be noted that in this embodiment, one end of the first sliding pin 251 is disposed between the two second rotating plates 244 and is hinged to the two second rotating plates 244. The second sliding pin 252 passes through the second through hole on the second locking plate 23.

[0049] The advantages of adopting the above preferred solution are: the hinge between the first sliding pin and the second sliding pin is conducive to the second sliding pin being inserted into or separated from the shredding assembly under the power transmitted by the first transmission component, thereby realizing the unlocking side opening or locking closure of the feeding assembly and the shredding assembly.

[0050] Preferred, such as Figure 1 and Figure 2 As shown, it also includes a reinforcing plate 4. A first arm is fixedly installed on the upper end of one side of the feeding assembly 6 and the upper end of one side of the chopping assembly 7. A second arm is fixedly installed on the lower end of one side of the feeding assembly 6 and the lower end of one side of the chopping assembly 7. The first arm on the feeding assembly 6 is hinged to the first arm on the chopping assembly 7. The second arm on the feeding assembly 6 is hinged to the second arm on the chopping assembly 7. The top and bottom ends of the reinforcing plate 4 are fixedly connected to the first arm and the second arm respectively.

[0051] It should be noted that in this embodiment, the top end of the reinforcing plate 4 is fixedly connected to the first arm on the feeding assembly 6 or the first arm on the chopping assembly 7, and the bottom end of the reinforcing plate 4 is fixedly connected to the second arm on the feeding assembly 6 or the second arm on the chopping assembly 7.

[0052] The advantages of adopting the above preferred solution are: the first arm and the second arm facilitate the hinge connection between the feeding assembly and the shredding assembly, and the reinforcing plate helps to enhance the connection strength between the feeding assembly and the shredding assembly when the side is unlocked.

[0053] Preferred, such as Figure 1 and Figure 2 As shown, it also includes an indicator mechanism 5, which includes an indicator rod 51, a pin 52 and an indicator hole 53. The indicator hole 53 is opened on the side wall of the chopping assembly 7, and the top end of the indicator rod 51 is hinged to the side wall of the chopping assembly 7 through the pin 52.

[0054] It should be noted that in this embodiment, the hydraulic cylinder in the silage machine drives the turntable to rotate, and the chopping assembly 7 is mounted on the turntable and changes its posture with the movement of the hydraulic cylinder. The side opening is only unlocked when the chopping assembly 7 is in certain specific postures to avoid interference with other functional structures on the silage machine. Therefore, in order to make it easier for the operator to know when to unlock the side opening, an indicator mechanism 5 is provided. Only when the bottom end of the indicator rod 51 points to the indicator hole 53 does it mean that the chopping assembly 7 is in a posture that will not cause interference when unlocked, and the side opening can be unlocked at this time.

[0055] The advantages of adopting the above preferred solution are: the pin shaft facilitates the rotation of the indicator rod as the chopping assembly is adjusted. When the bottom of the indicator rod points to the indicator hole, it means that the chopping assembly is in a position where it will not interfere with other functional structures of the silage machine when it is unlocked and opened. At this time, it can be unlocked and opened.

[0056] The working process of this embodiment is described below: like Figures 1 to 5 As shown: When it is necessary to unlock the feeding assembly 6 and the chopping assembly 7 to open to the side, first confirm whether the bottom end of the indicator rod 51 is facing the indicator hole 53. If so, the feeding assembly 6 and the chopping assembly 7 can be unlocked to the side. If not, the posture of the chopping assembly 7 needs to be adjusted by the hydraulic cylinder on the forage machine until the bottom end of the indicator rod 51 is facing the indicator hole 53. Then rotate the adjusting bolt 153 to release one end of the adjusting bolt 153 from contact with the movable locking hook 13, and manually rotate the movable locking hook 13 to release the engagement with the inner tube 11. Next, rotate handle 213 to drive relative displacement between handle 213 and drive rod 214, thereby causing the first rotating plate 241, rotating rod 242 and two second rotating plates 244 to rotate synchronously. During the rotation of the two second rotating plates 244, the two second transmission components 25 will be driven to move synchronously until the second sliding pin 252 is pulled out from the first locking plate 22. However, it should be noted that the second sliding pin 252 cannot be pulled out from the second locking plate 23. Then, pull the other end of the limit rod 3 out of one of the insertion holes on the chopping assembly 7. At this point, there is no longer any limit interference between the feeding assembly 6 and the chopping assembly 7. Manually rotate the feeding assembly 6 and the chopping assembly 7 to a suitable angle so that the operator can directly observe the internal components of the silage machine. Finally, insert the other end of the limit rod 3 into another insertion hole on the chopping assembly 7 to limit and fix the feeding assembly 6 and the chopping assembly 7 after unlocking and opening the side, so that the internal parts of the silage machine can be inspected, maintained or replaced in the future.

[0057] When it is necessary to lock the feeding assembly 6 and the chopping assembly 7, simply reverse the above steps; they will not be repeated here.
