Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a system in which a pulling device, a reaping device, and a reaped husk culm are attached to the front part of a traveling vehicle body equipped with a threshing device, with the tip of the harvested husk being locked and the stock end being clamped. The present invention relates to a combine harvester connected to a reaping pre-processing section equipped with a reaped husk transporting device that transports the reaped husks and supplies them to the threshing tweed chain in a sideways position.

[Prior art]

In general, the above-mentioned threshing machines are constructed to supply the harvested husks to a single large-diameter handling cylinder, which causes the following problems.

[Problem that the invention seeks to solve]

In addition, the large-diameter handling cylinder exerts a handling action by wrapping around the supplied shell culm, so the effective handling action range is limited even in the chair force of the lower handling method and the upper handling method, and the effective handling action range is limited. There are restrictions on the amount of culm insertion. Further, it is preferable that the culm direction to be supplied be perpendicular to the rotational axis of the handling barrel, and the tips of the culms should be in a spread state. Therefore, in the past, the lifting path of the lifting device was set long, and the culm was raised up to the tip using a locking claw installed on the device, and while the tip was handled within the path, the angle of the entire lifting device with respect to the ground was adjusted as much as possible. By setting this so that the angle is close to 0 degrees, the longitudinal length of the aircraft can be reduced.

Additionally, the device was prevented from becoming larger.

However, when the lifting device is provided as described above, the backward feed component of the driving speed of the locking pawls etc. arranged on the mounting plate becomes small, so it is necessary to adjust this component to match the traveling speed of the aircraft. The driving speed of the pawl etc. in the raising path becomes high, and the tip of the shell culm is unnecessarily loosened, which causes the problem that the shell culm is easily shed before being harvested.

Also, as mentioned above? Due to the limitations of the push-in type for 1" general culms, a mechanism for adjusting the handling depth is required, so it becomes necessary to provide a movable part in the conveying device for adjusting the handling depth, and the drive system also needs to be installed. There are complications.

In addition, as the culm conveying device changes the culm to a sideways posture during conveyance, the tip locking conveyance mechanism and the stock head clamping conveyance mechanism are configured to be spaced apart from each other as the direction of normal conveyance increases. In addition, since the handling depth adjustment mechanism is configured to adjust the delivery distance of the shell culm by moving the common stock head clamping conveyance mechanism away from or closer to the feed chain, the handling depth adjustment mechanism is configured to adjust the delivery distance of the shell culm. When transporting culms, due to changes in the posture of the shell culms, and due to handling depth adjustment,
There have been cases where the locking force of the ear locking and conveying mechanism causes a problem in which the grain stalks are pulled out from the stock head clamping and conveying mechanism.

Furthermore, in the case where the front end of the cut husk culm conveying device is configured to swing up and down to adjust the handling depth, the vertical dimensions of the lifting device must be increased to ensure this swing range. There is a problem that the device becomes larger.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a combine harvester 1 in which the above problems can be solved by rational modification of the threshing device.

[Means to solve the problem]

The present invention is characterized in that the threshing device and the feed chain drive and rotate the shell culm, which is held and conveyed in a horizontally suspended position, around an axis along the shell culm conveyance direction.
The ear tip is configured to be handled and threshed by a large number of handling rotors arranged in parallel with each other with overlapping rotational trajectories in the direction of the husk culm body, and which is configured to handle and thresh the grain by turning it toward the ear side, and which constitutes the reaped husk culm conveying device. The interval between the locking conveyance mechanism and the stock clamp conveyor 11 (!-) is set and fixed approximately constant over the entire length of the conveyance path, and the front P
The starting end of the tip locking and conveying mechanism is set close to the height of the lifting end of the lifting device <K, and its functions and effects are as follows.

[Function] In other words, as mentioned above, the threshing device is composed of a large number of handling rotors, and the supplied husk culm is acted upon by each group of handling rotors in the direction toward the ear tip, so that the husk culm is affected by this handling rotation. Even if the grain is fed in a position slightly deviated from the direction perpendicular to the axis of rotation of the grain, the culm does not stretch, so there is no drop in threshing performance. There is no need to clean the tips in advance. Similarly, since the threshing device is composed of a large number of handling rotors, the threshing can be carried out without any problem even if the amount of inserted culm to be supplied is not constant, so there is no particular need for a handling depth adjustment mechanism.

In addition, for the above reasons, it is possible to set the interval between the ear tip locking conveyance mechanism and stock head clamping conveyance mechanism of the harvested husk culm conveyance device as described above. In addition, there is no need to take into account the swinging range of the front end of the cutting husk culm conveying device when constructing the lifting device.

In addition, since the starting end of the tip locking and conveying mechanism is set at the height of the lifting end of the lifting device, the culm can be transferred smoothly at this location. Further, since the threshing device is composed of a large number of handling rotors, the diameter of each handling rotor can be small, and the vertical dimensions of the threshing device can be reduced.

〔Effect of the invention〕

Therefore, it is not necessary to clear the husk before supplying it to the threshing device, and it is also necessary to take into account the swing range of the front end of the reaped husk conveyance mechanism when adjusting the handling depth, so the angle of the pulling device relative to the ground is adjusted. It can be set small, and the vertical dimensions of the lifting device can be made small to the extent that the locking claws or the like can hardly act on the tips of the ears. As a result, the lifting device is downsized and grain culms are less likely to shed.

In addition, since there is no need for a handling depth adjustment mechanism, it is possible to take photos of the harvested husks! The structure of the transmission system etc. of the structure is simplified.

The manufacturing cost is reduced due to the low number of parts.

In addition, since the culm is only pulled out within the culm transport mechanism, the transfer from the culm transport mechanism to the feed chain is ensured, and the generation of long straw and large amounts of dust in the handling room is reduced. Ru.

In addition, since the grain culm is smoothly delivered from the raising device to the harvested husk culm transport mechanism, the deterioration of the posture of the grain culm within the transport M-way is unlikely to deteriorate the threshing performance.

Furthermore, since the vertical dimensions of the threshing device can be reduced, the machine body can be made more compact, and a configuration in which a VCC coarse grain tank is mounted on the top of the threshing device is possible.

As described above, grains are shed before they are supplied into the handling chamber, which reduces the number of parts and production costs, and reduces the generation of long straw and large amounts of dust in the handling chamber. We have now provided a combine harvester with less deterioration in threshing performance due to poor posture, a more compact machine body, and a grain tank that can be mounted on top of the threshing device.
