Description

[Detailed explanation of the invention] The present invention has a threshing machine mounted on the frame of a traveling cart so that it can be loaded and unloaded freely, and when the threshing machine is unloaded, the traveling cart can be used as a vehicle for transporting other objects such as bundles of straw. In addition, the threshing machine is configured so that it can be used for stationary threshing work, and the threshing machine frame has a structure that allows for easy loading and unloading of the threshing machine. This invention relates to an improvement in a mobile threshing machine equipped with wheels.

In conventional mobile threshing machines, wheels are provided on the threshing machine frame, which makes loading and unloading work easier.However, since the wheels are mounted on a shaft so as to protrude from the bottom of the threshing machine frame, it is difficult to load and unload the threshing machine during stationary threshing work. Or, when the threshing machine is lowered to the ground when used as a transport vehicle, the wheels support the weight of the threshing machine, and excessive load is likely to be applied to the wheel spindle, so the function is only for loading and unloading. Not only must the wheels and their support shafts be made durable, but also the mud that adheres to the wheels and support shafts and when the seeds are re-sown onto the trolley frame, the threshing on the trolley frame is difficult. This had the disadvantage that the aircraft could not be moved smoothly.

Furthermore, since the threshing machine is removable and mounted on a traveling trolley via wheels that touch the ground at a single point, it becomes extremely unstable when moving, and has the inherent drawback that a stable mounting condition cannot be obtained. Therefore, it is difficult to put it into practical use.

The present invention provides a mobile thresher that is improved in these respects.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a mobile threshing machine, in which the threshing machine 4 can be freely loaded and unloaded on a frame 3 of a traveling trolley 2 equipped with a crawler traveling device 1. It is mounted on and fixed with bolts etc.

The threshing machine 4 is configured so that it can be slid in the direction of machine movement with respect to the trolley frame 3 by loosening bolts, and the threshing machine frame 5 has a loading/unloading guide so that this sliding can be done easily. A plurality of wheels 6... are provided.

In this embodiment, in such a mobile threshing machine G, a second
As shown in Figure A9 and Figure 3, a part of the threshing machine frame 5 is bent downward (or a separate member is fixed).
The threshing machine frame 5 has a leg portion T with a stable contact surface S.
, and the wheels 6 are mounted on the row side of each leg T so as to rotate around a horizontal axis at a higher position than the stable contact surface S. A part of the frame 3 is bent upward (or another member is fixed to it) to form a pair of parallel rails 8, and the wheels 6 run on these rails 8. It is constructed so that it can be transferred, and the side surface of this rail 8 is attached to the leg 1.
The positioning guide portion 9 is configured to slide on the side surface of the threshing machine 4 to restrict lateral vibration of the threshing machine 4, and the wheels 6 are fitted into the upper surface of the rail 8 at the end in the loading direction. The position of the threshing machine 4 in the longitudinal direction of the rail 8 is determined, and the stable contact surface S of the leg 1 is fixed as shown in the opening of FIG. A depressed portion 8a is formed thereon to provide support.

In order to facilitate loading and unloading, it is desirable that the bottom surfaces of the drop-in portions 8a be gently sloped at the starting end in the loading direction, as shown in the figure.

FIG. 4 shows another embodiment, in which rails 8... and wheels 6...
. is provided on the inner side of the leg portion γ.

In any of the embodiments, the legs γ are formed over the entire length of the threshing machine frame 5, but they may be formed locally at necessary locations.

In short, the present invention provides the threshing machine frame 5 with a leg T having a stable ground surface, and positions the lower surface of the wheel 6 above the stable ground surface of the leg T. A rail 8 is disposed upwardly to protrude from the upper surface of the bogie frame 3 at a level equal to or greater than the height difference between the lower surface of the wheel and the stable ground contact surface, so that the stable ground contact direction is raised. When the threshing machine 4 is lowered to the ground, the weight is supported by the legs 1, so no overload is applied to the spindle of the wheels 6, which not only makes it easy to configure, but also allows the wheels 6 to support the legs 1. Since it is located above the stable contact surface S of part I, even though the wheels 6 are set in a fixed position, it is possible to prevent mud from adhering to the wheels 6 and their support shafts as much as possible.
Since the smooth rotation of the threshing machine 4 can be ensured, the loading and unloading work of the threshing machine 4 can be carried out easily.

In particular, in the present invention, a depressed portion 8a is formed at the end of the rail 8 in the loading direction to lower the wheel 6 by an amount commensurate with the lifting amount in the stable grounding direction S. Therefore, when the threshing machine is mounted and moved, By dropping the wheels 6 into the depressed portion 3af formed at the end of the rail 8 in the loading direction, the predetermined mounting position of the threshing machine can be easily determined, and the legs that have been lifted from the trolley frame can be stabilized. The grounding direction S descends by the floating amount and lands on the truck frame.

That is, the threshing machine can be transferred from an unstable support state through wheels that are movable and point-touched to the ground to a stable support state through stable ground contact surfaces of the legs.

Therefore, it has come to have an extremely significant practical advantage in that a relatively simple fixing means for the threshing machine can be used.

In particular, if the positioning guide portion 9 for guiding the leg portion γ is formed as in the embodiment, the threshing machine 4 will not swing in irregular directions during loading and unloading, which will be more effective.
