Description

Technical Field

[0001] The utility model belongs to the field of crop harvesting machinery, in particular to a gearbox assembly with multiple gears, multiple speeds and forward and reverse rotation. Background Art

[0002] Corn is a crop grown extensively in northern China. Due to the vast expanses of land in the north, corn harvesting is currently mostly done with corn harvesters. With the advancement of mechanization, corn harvesters are often used in conjunction with husker machines, which simultaneously perform the husking operation after harvesting the corn, thus performing both harvesting and husking operations simultaneously and saving manpower and material resources.

[0003] During the harvesting operation, the walking speed of the existing corn harvester often does not match the working speed of the peeler. If the walking speed of the harvester is too fast and the working speed of the peeler is slow, too much corn will be harvested and piled up in the middle. If the walking speed of the harvester is too slow and the working speed of the peeler is fast, the work of the peeler will be wasted.

[0004] Furthermore, during the corn harvesting and husking process, corn often gets stuck in the husker or harvesting platform. When this happens with existing corn harvesters, the only way to remove the stuck corn is to shut down the engine and manually remove it, ensuring safety. This wastes both manpower and time. Summary of the Invention

[0005] The purpose of the utility model is to solve the problem that the walking speed of the existing corn harvester does not match the working speed of the peeler and automatically solve the problem of corn getting stuck, and to provide a multi-gear, multi-speed and forward and reverse gear box assembly.

[0006] A multi-gear, multi-speed, forward and reverse gearbox assembly comprises a gearbox 1, a pulley 2 and a gear rack 3, wherein the pulley 2 is coaxially fixedly connected to the gearbox main shaft 11 by a key, and the gear rack 3 is fixedly arranged on the top of the gearbox 1;

[0007] The gear rack 3 is provided with an anti-rotational shift fork 31, an anti-rotational pull plate 32, a shift fork 33 and a shift adjustment plate 34; the anti-rotational shift fork 31 and the shift fork 33 are arranged inside the gearbox 1, and the anti-rotational shift fork 31 cooperates with the gearbox main shaft 11 through a gear, and the shift fork 33 cooperates with the gearbox output shaft through a gear; the anti-rotational shift fork 31 is connected to the anti-rotational pull plate 32, and the shift fork 33 is connected to the gear adjustment plate 34.

[0008] Furthermore, the gearbox 1 is provided with four speed gears.

[0009] The working process and working principle of this utility model:

[0010] The pulley 2 described in the present invention is connected to the rear end pulley of the generator through a belt. The engine outputs energy, and the belt is driven by the rear end pulley of the engine. The belt drives the pulley 2 described in the present invention to rotate, thereby driving the gearbox main shaft 11 to rotate.

[0011] The gearbox 1 is provided with a plurality of speed gears. By pulling the gear adjustment plate 34, the gear fork 33 can be shifted between the speed gears. Through the engagement of the large and small gears inside the gearbox 1, the speed input to the gearbox 1 is converted into a plurality of different speeds, which are transmitted to the longitudinal gearbox output shaft 12 through the bevel gear. The gearbox output shaft 12 is connected to the reversing box of the cutting table and the peeling machine through the transmission shaft, and different speeds are input to the reversing box of the cutting table and the peeling machine. The reversing box of the cutting table and the peeling machine uses different speed power to drive the cutting table and the peeling machine to work.

[0012] By shifting the counter-rotation pull plate 32 of the gear rack 3 to the forward direction, the counter-rotation shift fork 31 disposed inside the gearbox 1 is engaged with the gear of the gearbox main shaft 11 in the forward direction, thereby driving the gearbox output shaft 12 to rotate forward.

[0013] The counter-rotation pull plate 32 of the gear rack 3 is moved to the reverse direction, so that the counter-rotation shift fork 31 provided inside the gearbox 1 engages with the gear of the gearbox main shaft 11 in the reverse direction, driving the gearbox output shaft 12 to rotate reversely.

[0014] When the anti-rotation pull plate 32 is in the forward position, the transmission output shaft 12 rotates forward, driving the transmissions of the header and peeler to work forward. When the anti-rotation pull plate 32 is in the reverse position, the transmission output shaft 12 rotates reversely, driving the transmissions of the header and peeler to work reversely. If corn is stuck in the header or peeler, pulling the anti-rotation pull plate 32 to the reverse position causes the transmission output shaft 12 to reverse, driving the transmissions of the header and peeler to work reversely, loosening the stuck corn and allowing it to fall.

[0015] Beneficial effects of the utility model:

[0016] The utility model is provided with multiple speed gears, and the working speed of the peeling machine can be adjusted by adjusting the speed.

[0017] The working speed matches the traveling speed of the corn harvester.

[0018] The utility model drives the peeling machine to rotate in the positive and negative directions by adjusting the output shaft of the gearbox.

[0019] The speed box works forward and reverse, which can solve the problem of corn getting stuck in the cutting table or peeling machine, reducing the waste of manpower and material resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The gear rack 3 is provided with an anti-rotational shift fork 31, an anti-rotational pull plate 32, a shift fork 33 and a shift adjustment plate 34; the anti-rotational shift fork 31 and the shift fork 33 are arranged inside the gearbox 1, and the anti-rotational shift fork 31 cooperates with the gearbox main shaft 11 through a gear, and the shift fork 33 cooperates with the gearbox output shaft through a gear; the anti-rotational shift fork 31 is connected to the anti-rotational pull plate 32, and the shift fork 33 is connected to the gear adjustment plate 34.

[0026] The gearbox 1 is provided with four speed gears.

[0027] The working principle and working process of this embodiment:

[0028] The pulley 2 described in this embodiment is connected to the rear end pulley of the generator through a belt. The engine outputs energy, which drives the belt through the rear end pulley of the engine. The belt drives the pulley 2 described in the utility model to rotate, thereby driving the gearbox main shaft 11 to rotate.

[0029] The gearbox 1 is provided with a plurality of speed gears. By pulling the gear adjustment plate 34, the gear fork 33 can be shifted between the speed gears. Through the engagement of the large and small gears inside the gearbox 1, the speed input to the gearbox 1 is converted into a plurality of different speeds, which are transmitted to the longitudinal gearbox output shaft 12 through the bevel gear. The gearbox output shaft 12 is connected to the reversing box of the cutting table and the peeling machine through the transmission shaft, and different speeds are input to the reversing box of the cutting table and the peeling machine. The reversing box of the cutting table and the peeling machine uses different speed power to drive the cutting table and the peeling machine to work.

[0030] By shifting the counter-rotation pull plate 32 of the gear rack 3 to the forward direction, the counter-rotation shift fork 31 disposed inside the gearbox 1 is engaged with the gear of the gearbox main shaft 11 in the forward direction, thereby driving the gearbox output shaft 12 to rotate forward.

[0031] The counter-rotation pull plate 32 of the gear rack 3 is moved to the reverse direction, so that the counter-rotation shift fork 31 provided inside the gearbox 1 engages with the gear of the gearbox main shaft 11 in the reverse direction, driving the gearbox output shaft 12 to rotate reversely.

[0032] When the anti-rotation pull plate 32 is in the forward position, the transmission output shaft 12 rotates forward, driving the transmissions of the header and peeler to work forward. When the anti-rotation pull plate 32 is in the reverse position, the transmission output shaft 12 rotates reversely, driving the transmissions of the header and peeler to work reversely. If corn is stuck in the header or peeler, pulling the anti-rotation pull plate 32 to the reverse position causes the transmission output shaft 12 to reverse, driving the transmissions of the header and peeler to work reversely, loosening the stuck corn and allowing it to fall.
