Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a gearbox for a small corn harvester. Background Technology

[0002] The corn harvester gearbox is a type of gearbox product used in corn harvesters. It is an important component of the corn harvester, and its function is to change the transmission ratio of the vehicle, enabling the vehicle to move forward and backward, as well as to realize the interruption and transmission of engine power. In addition, the appropriate speed ratio and gear configuration can improve the efficiency of the harvester, and regular maintenance can extend its service life.

[0003] In mechanized agricultural operations, the traction box of a corn harvester is a core transmission component, and its performance directly affects the overall operating efficiency and adaptability of the machine. Existing small corn harvesters are generally limited by the single-gear configuration of their gearboxes, which exposes significant shortcomings when facing diverse farmland environments. In densely planted areas or soft, wet terrain, the lack of low-speed, high-torque gears in existing gearboxes can easily lead to clogging of the harvesting components or slippage of the walking mechanism. Conversely, in flat or sparsely planted areas, existing high-speed gears cannot fully utilize engine power, resulting in reduced operating efficiency. More importantly, traditional gearboxes lack integrated braking mechanisms, allowing only static parking by cutting off power, which poses a risk of rollover in sloping terrain, threatening operational safety and increasing equipment maintenance costs.

[0004] Therefore, there is an urgent need to provide a gearbox for a small corn harvester to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a gearbox for a small corn harvester.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a gearbox for a small corn harvester, comprising a gearbox body, a first shaft rotatably connected inside the gearbox body, a shifting mechanism for adjusting gears connected outside the first shaft, a second shaft rotatably connected inside the gearbox body, and a rotating mechanism fixedly connected outside the second shaft, wherein the shifting mechanism and the rotating mechanism cooperate to form two gears, high and low.

[0007] The gearbox body is rotatably connected to a third shaft, and the outside of the third shaft is connected to a shifting mechanism. The shifting mechanism cooperates with the rotation mechanism to form three gears.

[0008] The gearbox body is rotatably connected to a fourth shaft and a fifth shaft, and a steering mechanism for steering and synchronization is connected between the fourth shaft and the fifth shaft. A braking mechanism for braking is connected to the outside of the third shaft, and a sixth shaft is rotatably connected inside the gearbox body.

[0009] The present invention is further configured such that: the shifting mechanism includes a first gear slidably connected to the outside of a first shaft; a second gear slidably connected to the outside of the first shaft; a first limiting ring located between the first gear and the second gear connected to the outside of the first shaft; a first shift lever connected to the outside of the first limiting ring; a third gear fixedly connected to the outside of the first shaft; the first shaft is connected to the output end of the engine; and the first gear and the second gear are double gears.

[0010] Through the above technical solution, the function of the gear shifting mechanism is to shift gears via the first shaft. The first gear and the first gear are double gears. By moving the first shift lever, the first limiting ring moves, which in turn moves the first gear and the first gear, respectively, to mesh with the second gear and the second gear, forming two gears, high and low. In the first gear, the first shaft rotates, which in turn rotates the first gear, which in turn rotates the second gear, which in turn rotates the second shaft. In the second gear, the first shaft rotates, which in turn rotates the first gear, which in turn rotates the second gear, which in turn rotates the second shaft. This allows for quick and simple gear shifting.

[0011] The present invention is further configured such that: the rotating mechanism includes a second gear fixedly connected to the outside of the second shaft, and a second gear, a second gear, and a second gear are also fixedly connected to the outside of the second shaft.

[0012] Through the above technical solution, the function of the rotating mechanism is to cooperate with the shifting mechanism and the toggle mechanism to form multiple gears; the second gear can mesh with the first gear, the second gear can mesh with the first gear, the second gear can mesh with the third gear, and the second gear can mesh with the third gear, forming gears respectively; through multiple gears, the operator can freely select the required gear when using it, increasing flexibility and convenience.

[0013] The present invention is further configured such that: the actuating mechanism includes a third bevel gear connected to the outside of the third shaft; a third second gear and a third third gear are slidably connected to the outside of the third shaft; a second limiting ring is connected to the outside of the third shaft between the third second gear and the third third gear; a second shift lever is connected to the outside of the second limiting ring; and the third second gear and the third third gear are double gears.

[0014] Through the above technical solution, the function of the shifting mechanism is to shift gears via the third shaft. The second and third gears are double gears. By shifting the second shift lever, the second limit ring moves, which in turn moves the second and third gears, meshing with the second and third gears, the second and fourth gears, and the first and third gears respectively, forming three gear positions. In the first gear position, the second shaft rotates, causing the second and third gears to rotate, which in turn causes the second and third gears to rotate, and the third shaft to rotate. In the second gear position, the second shaft rotates, causing the second and fourth gears to rotate, which in turn causes the third and third gears to rotate, and the third shaft to rotate. In the third gear position, the first shaft rotates, causing the first and third gears to rotate, which in turn causes the third shaft to rotate. This allows for quick adjustment of multiple gear positions, making it convenient, fast, simple, and practical.

[0015] The present invention is further configured such that: the steering mechanism includes a fourth bevel gear fixedly connected to the top of the fourth shaft; the third bevel gear meshes with the fourth bevel gear; a fourth second bevel gear is fixedly connected to the bottom of the fourth shaft; a fifth first gear and a fifth fourth gear are connected to the outside of the fifth shaft; the fifth first gear and the fifth fourth gear are steering gears; and a steering rod is connected to the top of both the fifth first gear and the fifth fourth gear; a fifth second bevel gear meshing with the fourth second bevel gear is also fixedly connected to the outside of the fifth shaft; and a fifth third ring is fixedly connected to the outside of the fifth shaft.

[0016] Through the above technical solution, the steering mechanism achieves forced steering or synchronization through the steering lever. The fifth and fourth gears are steering gears; by moving the steering lever, they engage or disengage with the fifth and second helical gears and the fifth and third ring gears respectively, achieving forced steering or synchronization. Rotation of the third shaft drives the third and first helical gears to rotate, which in turn drives the fourth shaft to rotate, which in turn drives the fourth and second helical gears, and finally the fifth and second helical gears. At this point, the steering lever can be moved to achieve steering. In the first direction, rotation of the fifth and second helical gears drives the fifth shaft to rotate, which in turn drives the fifth and third ring gears, and then the fifth and fourth gears to rotate. In the second direction, rotation of the fifth and second bevel gears drives the fifth and first gears to rotate. Steering and synchronization can be achieved quickly through the rotating lever, making it convenient, fast, simple, and practical.

[0017] The present invention is further configured such that: a sixth gear that meshes with the fifth gear is fixedly connected to the outside of the sixth shaft; a sixth shaft is fixedly connected to one side of the sixth gear; a sixth second gear that meshes with the fifth gear is fixedly connected to the outside of the sixth shaft; and a sixth second shaft is fixedly connected to one side of the sixth second gear.

[0018] Through the above technical solution, the sixth shaft can cooperate with the steering mechanism to achieve the steering function; in the first direction, the fifth and fourth gears rotate, driving the sixth and second gears to rotate, which in turn drives the sixth and second shafts to rotate; in the second direction, the fifth and first gears rotate, driving the sixth and first gears to rotate, which in turn drives the sixth and first shafts to rotate; through the cooperation of the sixth shaft, the sixth and first shafts can be driven to rotate respectively.

[0019] The present invention is further configured such that: the braking mechanism includes a brake disc connected inside the gearbox body, the brake disc is sleeved on the outside of the third shaft, and a brake lever is connected to the outside of the brake disc.

[0020] Through the above technical solution, the function of the braking mechanism is to brake the main body of the gearbox; by pulling the brake lever, the brake disc can be braked, thereby braking the main body of the gearbox and realizing the parking function.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model achieves dual-gear switching through a shifting mechanism. The double-gear assembly, in conjunction with a limiting ring, enables the first and second shaft gears to form a high-low speed transmission ratio, meeting the low-speed, high-torque requirements of high-density planting areas and the high-speed operation requirements of flat terrain. The rotating and actuating mechanisms work together to achieve multi-gear expansion. The second shaft gear set and the third shaft double-gear assembly combine to form three extended gears, improving engine power utilization. The steering mechanism achieves bidirectional power distribution. A bevel gear transmission chain works with the steering gear set, and the steering lever controls the meshing state of the fifth shaft gear, enabling switching between forced steering and synchronous transmission modes.

[0023] 2. This utility model achieves an instant parking function through a braking mechanism, using a brake disc and brake lever that directly act on the third shaft to provide reliable braking protection when operating on slopes; the whole system forms a complete power adjustment system through multiple sets of gear meshing and shifting operations, enabling the harvester to have the ability to pass through complex plots, high efficiency in flat areas, and safety when operating on slopes, significantly improving the operational adaptability and ease of operation of agricultural machinery.

The first shaft 2 is connected to the output end of an engine. The first gear 301 and the second gear 302... The gear shifting mechanism 3 is a double gear system, and its function is to shift gears via the first shaft 2. The first gear 301 and the first gear 302 are double gears. By moving the first shift lever 304, the first limiting ring 303 moves, which in turn moves the first gear 301 and the first gear 302, respectively, to mesh with the second gear 501 and the second gear 502, forming two gears, one high and one low. In the first gear, the first shaft 2 rotates, which in turn rotates the first gear 301, the second gear 501, and the second shaft 4. In the second gear, the first shaft 2 rotates, which in turn rotates the first gear 302, the second gear 502, and the second shaft 4. This allows for quick and easy gear shifting.

[0035] like Figures 1-3 As shown, a second shaft 4 is rotatably connected inside the gearbox body 1, and a rotating mechanism 5 is fixedly connected to the outside of the second shaft 4. The shifting mechanism 3 cooperates with the rotating mechanism 5 to form two gears, high and low.

Through multiple gears, the operator can freely select the required gear when using it, increasing flexibility and convenience.

[0036] like Figures 1-4As shown, a third shaft 6 is rotatably connected inside the gearbox body 1. A shifting mechanism 7 is externally connected to the third shaft 6. The shifting mechanism 7 cooperates with the rotating mechanism 5 to form three gears. The shifting mechanism 7 includes a third bevel gear 701 fixedly connected to the outside of the third shaft 6. A third second gear 702 and a third third gear 703 are also slidably connected to the outside of the third shaft 6. A second limiting ring 704 is located between the third second gear 702 and the third third gear 703, and a second shift lever 705 is externally connected to the second limiting ring 704. The third second gear 702 and the third third gear 703 are double gears. The function of the shifting mechanism 7 is to shift gears via the third shaft 6. The third second gear 702 and the third third gear 703 are double gears. By shifting the second shift lever 705, the second limit ring 704 moves, causing the third second gear 702 and the third third gear 703 to move, respectively meshing with the second third gear 503, the second fourth gear 504, and the first third gear 305 to form three gears. In the first gear, the second shaft 4 rotates, causing the second third gear 503 to rotate, the third second gear 702 to rotate, and the third shaft 6 to rotate. In the second gear, the second shaft 4 rotates, causing the second fourth gear 504 to rotate, the third third gear 703 to rotate, and the third shaft 6 to rotate.

This allows for quick adjustment of multiple gears, making it convenient, fast, simple, and practical.

[0037] like Figures 7-8As shown, a fourth shaft 8 and a fifth shaft 9 are rotatably connected within the gearbox body 1. A steering mechanism 10 for steering and synchronization is connected between the fourth shaft 8 and the fifth shaft 9. The steering mechanism 10 includes a fourth first bevel gear 1001 fixedly connected to the top of the fourth shaft 8, a third first bevel gear 701 meshing with the fourth first bevel gear 1001, a fourth second bevel gear 1002 fixedly connected to the bottom of the fourth shaft 8, a fifth first gear 1003 and a fifth fourth gear 1004 externally connected to the fifth shaft 9. The fifth first gear 1003 and the fifth fourth gear 1004 are steering gears, and a steering rod 1005 is connected to the top of each of the fifth first gear 1003 and the fifth fourth gear 1004. A fifth second bevel gear 1006 meshing with the fourth second bevel gear 1002 is also fixedly connected to the outside of the fifth shaft 9. A fifth third ring 1007 is fixedly connected to the outside of the fifth shaft 9. The function of the steering mechanism 10 is to guide the steering rod 1005 through the steering mechanism 1006. 005 enables forced steering or synchronization. The fifth gear 1003 and the fifth fourth gear 1004 are steering gears. By moving the steering lever 1005, they engage or disengage with the fifth second bevel gear 1006 and the fifth third ring 1007 respectively, achieving forced steering or synchronization. Rotation of the third shaft 6 drives the third first bevel gear 701 to rotate, which in turn drives the fourth first bevel gear 1001, the fourth shaft 8 to rotate, the fourth second bevel gear 1002 to rotate, and the fifth second bevel gear 1006 to rotate. At this time, the steering lever 1005 can be moved to achieve steering. In the first direction, rotation of the fifth second bevel gear 1006 drives the fifth shaft 9 to rotate, which in turn drives the fifth third ring 1007 to rotate, and the fifth fourth gear 1004 to rotate. In the second direction, rotation of the fifth second bevel gear 1006 drives the fifth first gear 1003 to rotate. Steering and synchronization can be achieved quickly by rotating the lever 1005, which is convenient, fast, simple, and practical.

[0038] like Figures 1-5 As shown, a braking mechanism 11 for braking is externally connected to the third shaft 6, and a sixth shaft 12 is rotatably connected inside the gearbox body 1. The braking mechanism 11 includes a brake disc 1101 connected inside the gearbox body 1, the brake disc 1101 is sleeved on the outside of the third shaft 6, and a brake lever 1102 is externally connected to the brake disc 1101. The function of the braking mechanism 11 is to brake the gearbox body 1; by pulling the brake lever 1102, the brake disc 1101 can be braked, thereby braking the gearbox body 1 and realizing the parking function.

[0039] like Figures 7-8As shown, a sixth gear 1008, meshing with a fifth gear 1003, is fixedly connected to the outside of the sixth shaft 12. A sixth shaft 1009 is fixedly connected to one side of the sixth gear 1008. A sixth gear 1010, meshing with a fifth gear 1004, is fixedly connected to the outside of the sixth shaft 12. A sixth shaft 1011 is fixedly connected to one side of the sixth gear 1010. The sixth shaft 12 can cooperate with the steering mechanism 10 to achieve the steering function. In the first direction, the fifth gear 1004 rotates, driving the sixth gear 1010 to rotate, which in turn drives the sixth shaft 1011 to rotate. In the second direction, the fifth gear 1003 rotates, driving the sixth gear 1008 to rotate, which in turn drives the sixth shaft 1009 to rotate. The sixth shaft 12 can be used to drive either the sixth shaft 1009 or the sixth shaft 1011 to rotate.

[0040] In use, this invention achieves power transmission regulation through multiple sets of gear meshing and shifting operations. After the engine power is input through the first shaft 2, operating the first shift lever 304 can drive the first limiting ring 303 to move axially, causing the first gear 301 or the first second gear 302 to mesh with the second gear 501 or the second second gear 502 on the second shaft 4, forming two basic transmission gears. When more gears are needed, the second shift lever 705 drives the second limiting ring 704 to move, causing the third second gear 702 or the third third gear 703 on the third shaft 6 to mesh with the second third gear 503, the second fourth gear 504, or the first third gear 305 on the second shaft 4, thereby combining three extended gears. During steering operations, the third shaft 6 drives the fourth shaft 8 to rotate through the third first bevel gear 701, and the fourth shaft 8 then rotates through the fourth second bevel gear 701. Gear 1002 drives the fifth shaft 9 to rotate. At this time, operating the steering lever 1005 can cause the fifth first gear 1003 or the fifth fourth gear 1004 to disengage or mesh with the fifth second bevel gear 1006 and the fifth third ring 1007, thereby achieving a forced switch in the power transmission direction or maintaining synchronization. When braking is required, pulling the brake lever 1102 causes the brake disc 1101 sleeved on the third shaft 6 to generate frictional resistance, thereby stopping the entire machine by braking the third shaft 6. During the shifting of gears, the first shaft 2 can control the power input state through the clutch. By alternating the meshing of different gear sets, the transmission ratio can be changed, enabling the harvester to cope with complex plots in a low-speed, high-torque mode, and to release engine power in flat areas through high-speed gears. Combined with the two-way power distribution of the steering system and the instant parking function of the braking device, a complete power transmission regulation and safety control system is formed.
