Description

[Detailed description of the invention] The invention makes the threshing device detachable from the traveling machine,
This invention relates to a harvester in which a traveling body from which a threshing device has been removed can be used as a transport vehicle.

Traditionally, this type of harvester was installed on the platform of a traveling aircraft.
The bottom of the lower frame was formed flat so that it could be positioned stably even when it was taken off the machine and placed on the ground. If the threshing device is loaded onto and unloaded from the base of the traveling machine, it is troublesome as it requires a large number of hands and a special hoisting device, and the threshing device may accidentally fall over. There was also the risk of damaging the side wall.

In other words, when loading this threshing device onto the machine platform, a lifting device is used to lift the threshing device in a horizontal position to a certain height, and there is a gap between the lower frame and the ground that is sufficient for the platform of the traveling machine to enter. However, it is difficult to use a threshing device on soft ground such as in a field, so it is generally done by tilting the threshing device to some extent. While maintaining the threshing device in an artificially inclined position, the traveling machine is moved so that there is enough space between the inclined upper end of the lower frame and the ground to allow the end of the machine base of the running machine to enter. The machine was then moved to allow the end of the machine to enter the machine, and then the lower frame on the side that was in contact with the ground was lifted and loaded onto the machine. Due to the heavy weight of the threshing equipment itself, it is extremely difficult for a small number of people to tilt the threshing equipment to a large extent and reliably maintain its unstable position, which may cause the threshing equipment to fall over and cause injury to the workers. Inviting a situation,
There is a risk of damaging the side wall of the threshing device.
This inevitably required a large number of manpower.

The technical problem to be solved by the present invention is to stabilize the posture of the threshing device in a tilted state through a simple structural improvement when loading and unloading the threshing device to and from the platform of the traveling machine. The idea is to devise ways to perform manual loading and unloading work with a small number of people.

The technical means of this invention taken to solve the above problems are as follows:
The threshing device is configured to be attached to and removed from the base of the traveling machine by sliding movement, and a support frame having a ground contact portion at a position corresponding to the outside of the side wall in the removal direction of the threshing device is protruded from the threshing device. and the support frame is attached to the lower part of the threshing device in such a state that the distance between the inclined upper end of the lower frame of the threshing device and the ground is larger than the distance between the top surface of the base of the traveling machine and the ground. The mounting position for the threshing device is set so that the ground contact portion of the frame contacts the ground when the frame is tilted on the ground.

The effects obtained by taking the above technical measures are as follows.

In other words, the threshing device is provided with a support frame having a ground contact portion at a position corresponding to the outside of the side wall in the removal direction, and the support frame allows the sloped upper end of the bottom of the threshing device to be connected to the machine base of the traveling machine. Since it is tilted to a state higher than the ground height of the threshing device, by making the ground contact part of this support frame contact the ground, the attitude of the threshing device in the tilted state can be maintained by connecting one end of the lower frame of the threshing device and the above-mentioned support frame. Therefore, compared to the case of trying to maintain the tilted state of the threshing device with only one end of the lower frame in contact with the ground, it is extremely unstable at one point. This eliminates the inconvenience of requiring a large number of hands to support the threshing device from the front and back while it is in contact with the ground, and also eliminates the possibility of injury to the worker or damage to the side walls of the threshing device due to the threshing device tilting beyond a certain level. There is little risk of the threshing device being tilted, and it can be carried out by a small number of people while maintaining the threshing device in a stable tilted state, or by maintaining the threshing device in a tilted state after being unloaded from the platform of the traveling machine. This makes it easier to extract the end of the machine from between the lower frame and the ground, thereby providing a harvester that can be stably loaded and unloaded by a small number of people.

In addition, as a means for stabilizing the tilted state of the threshing device as described above, it is possible to construct it with an extremely simple structure simply by devising the installation position of the supporting frame, and furthermore, the By positioning the grounding part of the frame at a position corresponding to the outside of the side wall, the slope of the bottom surface of the lower frame of the threshing device is made sufficiently large, and the end of the machine platform is located in the space formed between the lower frame and the ground. By this, when lifting the end of the lower frame that was in contact with the ground,
The lifting force at the end can be reduced, making loading even easier.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, an engine 3 is mounted on the rear of a machine base 2 that is connected and supported by a crawler traveling device 1, and a control handle 4 is installed rearward from the middle part of the machine base 2. A harvester is shown in which a threshing device 5 is mounted on the front part so that it can be attached and detached by sliding back and forth.

This harvester is configured so that it can be used as a transport vehicle by loading other items such as paddy bags onto the platform 2 of the traveling machine from which the threshing device 5 has been removed.

In addition, a loop-shaped support frame 9 that protrudes to the outside of the front side wall S is fixed to the front part of the threshing device 5, and a dust exhaust pipe 8 for discharging straw waste etc. from the threshing device is protruded. and the front end of the lower frame 6 of the threshing device 5 and the support frame 9
The dust exhaust pipe 8 is located closer to the threshing device than the imaginary plane T that connects the ground contact portion at the tip of the dust pipe 8 .

The harvester of the present invention is constructed as described above, and when the threshing device 5 is removed and used as a transport vehicle, the front end of the support frame 9 is grasped as a handle and pulled toward the front of the machine. , as shown in FIG. 2A, the threshing device 5
Slide the threshing device 5 forward along the top of the machine base 2 so that it protrudes an appropriate length from the machine base 2, and then move the threshing device 5 forward and downward using the front end of the machine base 2 as a fulcrum, as shown in the opening of the figure. The front end of the lower frame 6 is brought into contact with the ground by tilting it, and then the tilting operation is continued until the front end of the support frame 9 and the front end of the lower frame 6 are in contact with the ground at two points, as shown in FIG. The threshing device 5 is tilted forward and placed in an inclined position.

The lower surface of the rear end of the lower frame 6 of the threshing device 5 in the tilted state is positioned higher than the threshing device mounting surface of the machine base 2, so the machine can be moved backward in this tilted state. By removing the front end of the machine stand 2 from the lower surface of the lower frame 6, the entire surface of the lower frame 6 of the threshing device 5 can be brought into contact with the ground as shown in FIG.

When the threshing device 5 is mounted on the traveling machine again to construct a harvester, the whole surface of the lower frame 6 is in contact with the ground as shown in Fig. 2, contrary to the case where the threshing device 5 is removed. Then, the threshing device 5 is brought into a tilted state with the grounding part of the support frame 9 touching the ground as shown in FIG.
As shown in the opening of the figure, after the rear end of the machine base 2 of the traveling machine enters the space under the lower frame 6, the threshing device 5 is tilted backward and the lower frame 6 is placed on the machine base 2. After loading the grain, the threshing device 5 can be pushed backward and slid backward along the top of the machine 2, as shown in FIG.
