During normal operation, the intermediate shaft 1-2 is connected with the driving shaft 1-5 through the sleeve connected with the gear sleeve 1-1. Therefore, when the driving wheel 7 rotates forwards, the middle shaft 1-2 is driven to rotate forwards by the driving wheel 7, and the middle shaft further drives the driving shaft 1-5 to rotate forwards.
In the normal rotation, although the gear 1-3 and the coupling sleeve gear 1-1 are both rotated, they do not function as a coupling, and thus power is directly transmitted to the drive shaft 1-5. That is, the power transmission path for the forward rotation is: drive pulley 7 → gear 1-3 → connecting gear sleeve 1-1 → output shaft 1-5. The output shaft 1-5 and the connecting shaft 1-2 run in the same direction.
In reverse rotation, the intermediate shaft 1-2 is disconnected from the sleeve connecting the gear sleeve 1-1, so that it is not directly connected to the drive shaft 1-5, but indirectly connected to the drive shaft 1-5 via the driven shaft assembly 2 and the intermediate shaft assembly 3, so that the drive shaft 1-5 is reversed, as will be described in detail below.

In one embodiment, gear 3-2 is connected to gear 1-3 of drive shaft assembly 1, whether it is desired to rotate the output shaft in a forward direction or in a reverse direction. The bearings 3-6 are used to mount the intermediate shaft assembly 3 on the harvester. The bush 3-4 and the key 3-5 play a limiting role, and are arranged on the intermediate shaft 3-1 together with the gear 3-2 and the gear 3-3. The gear 3-3 is used to connect with the gear 2-2 of the driven shaft assembly 2 shown in fig. 2, thereby transmitting power to the gear 2-2. The gear 2-2 is connected with a gear on a connecting gear sleeve 1-1 of the driving shaft assembly 1, and then power is transmitted to the driving shaft 1-5, so that the driving shaft 1-5 is reversely rotated.
The bearing 2-5 of the driven shaft assembly 2 is used for fixing the driven shaft assembly 2 on the harvester, and the sleeve 2-3 and the key 2-4 have limiting functions and are arranged on the driven shaft 2-1 together with the gear 2-2.
Thus, at the time of reverse rotation, the power transmission route is: the driving wheel 7 → the gear 1-3 is meshed with the gear 3-2 → the gear 3-3 is meshed with the gear 2-2 → the gear 2-2 is meshed with the gear on the connecting gear sleeve 1-1 → the connecting gear sleeve 1-1 drives the output shaft 1-5 to run, and the output shaft 1-5 runs in the opposite direction to the connecting shaft 1-2. At the moment, the connecting shaft 1-2 is meshed with the connecting gear sleeve 1-1 without splines.
During reverse rotation, the intermediate shaft 1-2 is disengaged from the connecting gear sleeve 1-1, so that power is not directly transmitted to the drive shaft 1-5, but is transmitted to the gear 3-2 through the gear 1-3 and is indirectly transmitted to the drive shaft 1-5 through the gear 3-3, the gear 2-2 and the gear on the connecting gear sleeve 1-1, thereby realizing reverse rotation of the drive shaft.
The connection and disconnection of the intermediate shaft 1-2 to the connecting gear sleeve 1-1 will be described with reference to fig. 5.

As shown in FIG. 5, according to an embodiment of the present invention, the shifting fork handle assembly 4 comprises a handle weld 4-1, a pin 4-2, a shifting fork 4-3, a limit shaft 4-4, a pressure spring 4-5, a flat pad 4-6, a cotter pin 4-7, and a pin 4-8. The assembly of the fork lever 4 constitutes an embodiment of the separating device of the invention.
The shifting fork 4-3 is sleeved on the connecting gear sleeve 1-1 and can push the connecting gear sleeve 1-1 left and right. The left side of the connecting gear sleeve 1-1 is provided with a connecting part which is connected with (for example sleeved and connected with) the shifting fork 4-3, so that the shifting fork 4-3 can move rightwards under the action of force.
The shifting fork 4-3 is connected with the handle welding 4-1 through the pin shaft 4-2, and the pin 4-8 plays a role in fixing. The handle weld 4-1 is used to receive an external force, such as a force from an operator, thereby moving the shift fork 4-3 to move the coupling gear sleeve 1-1 rightward, thereby disengaging from the intermediate shaft 1-2.
The handle welding joint 4-1 is provided with a limiting shaft 4-4, a pressure spring 4-5, a flat pad 4-6 and a split pin 4-7. The stopper shaft 4-4 has a shaft portion. As shown, the stem portion has a curved portion and a straight portion. The bending part can be stressed conveniently. For example to facilitate gripping by a person. The straight part is used for fixing the limiting shaft, for example, inserting the limiting shaft into a hole reserved on a harvester (such as a gearbox box body). These holes correspond to different operating positions or modes. As described in detail later. The pressure spring 4-5, the flat cushion 4-6 and the split pin 4-7 play a limiting role. The rod and the hole may be square, round, or other shapes, and need to be able to fit each other.
Returning to fig. 1, the pin 4-2 penetrates through the box body formed by the right gear box 5 and the left gear box 6 (for example, through a hole part) and enters the space of the box body, and the handle seam 4-1, the limiting shaft 4-4 and the like are left outside the box body, so that the external force can be conveniently received and the fixing can be conveniently carried out.
Fig. 6 is a schematic diagram illustrating the cooperation of the components in the forward rotation according to an embodiment of the present invention. As shown in fig. 6, according to an embodiment of the present invention, the limiting shaft 4-4 is manually pulled up, the adjusting handle is welded to 4-1, and the lower portion of the limiting shaft 4-4 is pulled up to the hole a, so that the device is in a normal working state, and the shifting fork 4-3 does not apply a right force to the connecting gear sleeve 1-1 (i.e., a force for disengaging from the intermediate shaft 1-2), so that the intermediate shaft 1-2 is connected to the connecting gear sleeve 1-1, and the force can be directly transmitted. At the moment, the connecting gear sleeve 1-1 is not connected with the gear 2-2. At the moment, the connecting gear sleeve 1-1 is not pushed by the shifting fork 4-3, and the connecting shaft device is in a normal working position.
As previously mentioned, the force transmission at this time is in the forward path: drive pulley 7 → gear 1-3 → connecting gear sleeve 1-1 → output shaft 1-5, in which split is transmitted from gear 1-3 to → gear 3-2 → gear 3-3 is engaged with gear 2-2, with no output. The output shaft 1-5 and the connecting shaft 1-2 run in the same direction.
Fig. 7 shows a schematic diagram of the cooperation of the components at idle, viewed from one direction, according to an embodiment of the invention. Fig. 8 shows a schematic diagram of the cooperation of the components at idle, viewed from another direction, according to an embodiment of the invention. As shown in fig. 7 and 8, the limiting shaft 4-4 is pulled up manually, and the handle is adjusted to be welded 4-1. The lower part of the limiting shaft 4-4 is shifted to the hole B, so that the gear is in a neutral state. At this time, the shift fork 4-3 applies a certain force (i.e., a force for disengaging from the intermediate shaft 1-2) to the connecting gear sleeve 1-1 to the right, so that the intermediate shaft 1-2 and the connecting gear sleeve 1-1 are disengaged, but at this time, the connecting gear sleeve 1-1 is not connected to the gear 2-2. So that the force of the intermediate shaft 1-2 is transmitted to the gear 2-2 through the gear 1-3, the gear 3-2 and the gear 3-3, but is not transmitted to the drive shaft 1-5. I.e. the neutral path of the force at this time: drive pulley 7 → gear 1-3 meshing with gear 3-2 → gear 3-3 meshing with gear 2-2 → no output. At the moment, the connecting shaft 1-2 is connected with the connecting gear sleeve 1-1 without splines, and power is cut off. The drive shaft arrangement is now in the first position because of the change in position of the coupling gear sleeve 1-1.
Fig. 9 is a schematic diagram illustrating the cooperation of the components in the reverse rotation according to an embodiment of the present invention. The limiting shaft 4-4 is pulled up manually, and the handle is adjusted to be welded 4-1. The lower portion of the stopper shaft 4-4 is shifted to the hole C (see fig. 6), and the shift fork 4-3 applies more rightward force (i.e., force for disengaging from the counter shaft 1-2) to the coupling gear sleeve 1-1, so that the counter shaft 1-2 and the coupling gear sleeve 1-1 are disengaged, and the coupling gear sleeve 1-1 is coupled to the gear 2-2. So that the force of the intermediate shaft 1-2 can be transmitted via the gear wheel 1-3, the gear wheel 3-2, the gear wheel 3-3 to the gear wheel 2-2 and further via the gear wheel connected to the gear wheel housing 1-1 to the drive shaft 1-5. That is, the reverse route is formed at this time: the driving belt pulley 7 → the gear 1-3 is meshed with the gear 3-2 → the gear 3-3 is meshed with the gear 2-2 → the gear 2-2 is meshed with the gear on the connecting gear sleeve 1-1 → the connecting gear sleeve 1-1 drives the output shaft 1-5 to run, and the output shaft 1-5 runs in the opposite direction to the connecting shaft 1-2. At the moment, the connecting shaft 1-2 is meshed with the connecting gear sleeve 1-1 without splines, so that force cannot be directly transmitted to the output shaft 1-5 from the connecting shaft 1-2. The drive shaft assembly is now in the second position because of the change in position of the coupling gear sleeve 1-1.
The pressure spring 1-4 can play a role in resetting, and when the connecting gear sleeve 1-1 is not acted by external force from the shifting fork 4-3, the connecting gear sleeve 1-1 can be pushed to be connected with the connecting shaft 1-2. The compression springs 1-4 constitute an embodiment of the resetting device of the invention.
Through the scheme, three-gear adjustment of forward rotation, neutral gear and reverse rotation of the output shafts 1-5 can be realized, and time and labor are saved.
Those skilled in the art will readily understand that various modifications can be adopted in the orientation of the technical idea of the present invention, for example, the driving wheel 7 may be replaced with a sprocket instead of the pulley 7. The matching modes of the gear, the chain wheel and the shaft are exchanged by flat keys or splines, so that the protection of the embodiment is not influenced. The utility model is not limited to the situation of positive and negative rotation of the conveying groove shaft of the harvester. Other occasions needing to realize the function of forward and reverse rotation also have protection rights.
When the harvester operation, the conveyer trough easily blocks, unable normal work, and at this moment, use this patent device can solve or alleviate this relevant problem. The utility model discloses a novel structure, convenient to use can realize corotation, neutral gear, reversal three fender regulation, labour saving and time saving through adjustment handle.
