Description
Technical Field
The utility model belongs to the technical field of agricultural machinery, and relates to a corn harvester capable of harvesting stems and ears.
Background
The straw feeding mechanism of the existing corn harvester with both stalks and ears is designed to rotate towards the feeding direction, so that cut straws are conveniently fed into the crushing mechanism, and then crushed, conveyed and collected in the crushing mechanism. In practical application, too many fed straws can appear due to unmatched running speed and engine rotating speed and other reasons when a manipulator operates, and the crushing mechanism is not timely crushed, so that the straws block the crushing mechanism, and the operation is interrupted; when the feeding mechanism is blocked, the blocked straws are manually cleaned at present; however, manual cleaning is often inconvenient, time and labor are wasted, the working efficiency of equipment is affected, and personal safety of cleaning staff is possibly threatened during cleaning.
In the problem of preventing straw blockage, some researchers also provide solutions, mainly comprising the following two methods:
one is driven by a hydraulic motor to drive the feeding mechanism to rotate reversely, but the hydraulic motor has the following defects:
1. the feeding structure in the existing stalk and spike harvesting corn machine needs a hydraulic motor with high rotating speed and high torque if the feeding structure adopts the hydraulic motor to provide power, but the hydraulic motor with high rotating speed and high torque has large volume and high price; the structural arrangement is difficult, and the cost performance is low;
2. when the stalk and ear harvesting corn machine works, the header, the hay cutter and the hay cutter feeding mechanism must meet the required transmission ratio to work normally; the transmission ratio of the header driven by the hydraulic motor and the feeding mechanism of the hay cutter and the hay cutter is easy to change, but is easier to cause blockage.
The other is that the feeding mechanism is driven by a bevel gear structure to rotate reversely, and the bevel gear structure has the following defects:
1. the bevel gear structure can only realize the reverse rotation of the cutting table, but can not realize the reverse rotation of the feeding part of the hay cutter, but in practical application, the feeding mechanism of the cutting table is blocked more;
2. the bevel gears can generate axial force when in transmission, and the axial force tends to separate the two bevel gears, so that the two bevel gears are separated when the load is large in actual use; resulting in a power transmission disconnection and failure.
In view of the above, the prior art harvester for harvesting corn from both ears and stems needs to solve the problem of blockage.
Disclosure of Invention

the input shaft is provided with an input gear, and the input gear is slidably arranged on the input shaft through a spline;
the output shaft is provided with a first output gear and a second output gear;
the intermediate shaft is provided with a reversing gear;
a shifting fork is fixedly arranged on the shifting fork shaft, and the other end of the shifting fork is clamped in the input gear groove;
the input gear slides on the input shaft through a shifting fork and is meshed with the output gear I or the reversing gear.
Further, a plurality of pin shaft holes are formed in the shifting fork shaft on the outer side of the shell, and pin shafts are arranged in the pin shaft holes to fix the positions of the shifting fork shafts; when moving the shift rail, the pin shaft is detached from the pin shaft hole, and then the shift rail is manually moved, so that the position of the input gear on the input shaft is moved.
Further, the positive and negative conversion box is arranged at the rear side of the straw feeding mechanism of the harvester, the end part of the outer side of the output shaft is provided with a chain wheel and a belt pulley, the chain wheel and the belt pulley transmit power to the cutting table, and the output shaft also transmits the power to the driving wheel of the hay cutter.
Further, the diameter of the first output gear is larger than that of the second output gear.
Furthermore, the reversing gear and the second output gear are in a constant meshed state.
The utility model has the beneficial effects that:
when the forward and reverse reversing box is used, the feeding mechanism rotates forward in normal operation, the feeding mechanism works the same as the existing harvester, once the blocking phenomenon occurs, after the harvester is stopped, the pin shaft is pulled out, and then the fork shaft is moved to drive the fork, so that the input gear is driven to shift, and the input gear is meshed with the output gear to be changed into the input gear meshed with the reversing gear; or the input gear is meshed with the reversing gear and is changed into the first meshing of the input gear and the output gear; then starting, reversing the straw feeding device, and after reversing, reversely spitting out the straw blocked in the feeding mechanism, so that the phenomena of time and labor waste during manual cleaning are avoided, and the working efficiency is improved; meanwhile, the threat to the personal safety of cleaning staff is avoided.
1. The cutting table is rigidly connected to the feeding mechanism of the hay cutter and then to the hay cutter, the transmission ratio is unchanged, and the cutting table and the hay cutter are not easy to be blocked;
2. the sliding gear adopts a straight gear, no axial force is generated during transmission, and the transmission is stable;
3. when the reversing function is started, the cutting table and the feeding mechanism of the hay cutter are reversed, and the blockage is discharged, so that the hay cutter and the fan are positively transmitted, and straw crushing and conveying are not influenced.
