Description

[Detailed Description of the Invention] The present invention relates to a grain culm bundle discharge device in a reaping and tying machine.

This type of grain culm bundle discharge device of a reaping and binding machine is designed to discharge grain bundles bound by a binding device to the outside of the machine body by a discharge rod that operates in conjunction with the binding device. Generally, a fixed type resistance rod is installed at the base of the plant, and the cutting speed, that is, the engine speed, is adjusted according to the vegetation conditions such as the wet and dry conditions of the field and the lodging state of the grain culm. At the same time, the harvesting work is being carried out.

However, this fixed type resistance rod is fixed at a fixed position regardless of the engine's low speed state or high speed state, which is linked to the aircraft's running speed and the release force of the tying device. At low speeds, the discharging force of the discharging rod becomes weak, and when the engine is at high speeds, it becomes strong, so the discharging distance of grain culm bundles is not constant and becomes irregular, and especially when the discharging force is weak, The disadvantage was that the grain culm bundles were often trampled.

By the way, as shown in FIG. 5, there is a movable and adjustable lever 16a fixed to the binding resistance rod 14a, which can adjust the working length of the binding resistance rod 14a projecting into the bundle release path. An adjustment device for the stock resistance rod has been tried.

However, with the stock resistance rod 14a that can only be adjusted manually, the protruding position of the stock resistance rod must be adjusted each time according to the engine speed, which makes the operation cumbersome. Since it is used in a fixed position, the above-mentioned drawbacks remain unsolved.

This invention was devised to solve the above-mentioned drawbacks of the base resistance rod, and the working length of the base resistance rod is
By making it possible to adjust the engine speed in conjunction with the operation of the control lever that controls the engine speed, the length of action of the stock resistance rod can be adjusted to match the discharge force of the discharge rod, which varies in conjunction with the rise and fall of the engine speed. An object of the present invention is to provide a grain culm bundle discharge device for a reaping and tying machine that can automatically adjust the grain culm bundle discharge distance to be approximately constant regardless of the engine rotation speed. be.

The grain culm bundle discharge device in the reaping and tying machine according to the present invention that achieves the above object is a reaping machine in which the grain culm bundles bound by the tying device are discharged to the side and outside of the machine body by a discharge rod that operates in conjunction with the tying device. In the tying machine, a stock resistance rod located below the discharge rod and protruding into the tying discharge path is connected to a control lever for controlling the engine rotation speed, and the control lever protrudes long when the engine is at a high speed position and shortly when the engine is at a low speed position. It is characterized by being interlocked and provided in such a relationship that the movement can be adjusted freely.

Hereinafter, the present invention will be described with reference to the drawings showing one embodiment.

As shown in the overall side view of FIG. 1, reference numeral 1 indicates running wheels for running the reaping and tying machine.
A reaping section A is located on the front side of the axis of the running wheel 1.
At the same time, a control section B equipped with an engine 2 is disposed on the rear side, and the engine 2 and the reaping section A are interlocked and connected via a transmission mechanism, and the engine 2 is connected to the running wheels 2 and the reaping section A. It is configured to drive part A.

The reaping section A includes a combing device 3 for combing the standing grain culms disposed on the tip side, and a combing device 3 disposed below the rear side of the combing device 3, which is reaped by a cutting blade (not shown) to remove the culm from the fuselage. A binding device 4 for binding grain culms conveyed to one side and upper and lower discharge rods 13 for discharging the bundled grain culm bundles to the outside of the machine are interlocked and connected to the engine 2 by a transmission mechanism. ing.

A control handle 5 is arranged above the control section B, and a control lever 6 for controlling the rotation speed of the engine 2 is provided on the hand side of the control handle 5. This control lever 6 is connected to a cable wire 19. It is connected to the throttle 20 on the engine 2 side through the throttle 20.

As shown in the plan view of FIG. 2, the bundling device 4 includes a packer 9 that reciprocates within a bundling release path 8 connected to the terminal end of the horizontal conveyance path 7 above the cutting blade to force-feed the grain stalks; Needle 1 that supplies the binding string
0 and a clutch door 11 that opens at a predetermined grain culm pressure is disposed on the rear side of the bundling release path 8, and a needle 10 is disposed on the front side of the bundling release path 8.
A tying device 12 for tying and cutting the binding cord of the needle 10 is arranged opposite to the tying device 1 .
A discharge rod 13 is disposed on the outside of 2, and these are interlocked and connected by a transmission mechanism.

A stock resistance rod 14 located inside the discharge end of the discharge rod 13 shown in FIG.

Both ends of the stock resistance rod 14 are attached to brackets 1 so as to be movable in the axial direction as shown in FIG.
5, and a stator 16 is fixed to this stock resistance rod 14 within a bracket 15.
A spring 17 is provided on one side of the stator 16 between the stator 16 and the bracket 15 by fitting it into the outer diameter of the base resistance rod 14, so that the tip of the base resistance rod 14 is always is energized and held in the direction of retreating from the bundle release path 8.

The stator 16 of the stock resistance rod 14 is connected to the inner tip side of a wire cable 18 whose base end is connected to the control lever 6 described above, and the outer tip side of the wire cable 18 is connected to the bracket 15 side. to be fixed.

Therefore, by manually operating the control lever 6 provided on the control handle 5, the wire cable 18 on the stock resistance rod 14 side connected to the control lever 6 is connected to the throttle on the engine 2 side. Since the wire cable 19 expands and contracts at the same time, at the low speed position of the control lever 6 shown by the solid line, where the engine speed increases, the active side of the stock resistance rod 14 is in the bundle release path 8 as shown by the solid line in FIG. In the low speed position shown by the dotted line of the control lever 6, which protrudes long and the engine speed is low, the stock resistance rod 14
The working side of the bundle protrudes briefly into the bundle release path 8 as shown in the inspection state shown in FIG.

Therefore, when the rotational speed of the engine 2 becomes high in conjunction with the operation of the control lever 6, and the pushing force for pushing out the grain culm bundles of the discharge rod 13 itself that discharges the grain culm bundle becomes strong, the discharge rod 13 As shown by the solid line in FIG. 2, the working length of the stock resistance rod 14 facing the grain culm bundle protrudes long into the bundling release path 8, increasing the resistance against the grain culm bundle K and limiting the release distance to the grain culm bundle. Ru.

Conversely, the rotational speed of the engine 2 becomes low in conjunction with the operation of the control lever 6, and the pushing force of the discharge rod 13 itself, which releases the grain culm bundle, increases in conjunction with the low speed rotation of the engine 2 to push out the grain culm bundle. When the grain culm bundle K is weakened, the acting side of the stock resistance rod 14 protrudes short into the bundling release path 8 as shown by the dotted line in FIG. The separation of the culm bundle K from the stock resistance rod 14 becomes better, and the ejection distance of the grain culm bundle increases, and even if the ejection force of the ejection rod 14 is weak, the grain culm bundle falls near the position of the running wheels, and It is possible to prevent the grain culm bundle from being trampled by the grain culm.

In short, the grain culm bundle release device in the reaping and tying machine of the present invention is a reaping and tying machine that discharges the grain culm bundles bound by the tying device to the side and outside of the machine body using a discharge rod that operates in conjunction with the tying device. In the machine, a control lever for controlling the rotational speed of the engine is configured such that a stock resistance rod located below the discharge rod and protruding into the bundling discharge path is protruded long when the engine is in a high speed position and short when the engine is in a low speed position. Since they are interlocked and connected in such a way that they can be moved and adjusted freely, it is possible to automatically adjust the length of the main resistance rod to correspond to the ejection force of the ejection rod, which fluctuates in conjunction with the rise and fall of the engine speed. .

Therefore, even if the engine speed is reduced by the control lever that controls the engine speed, and the pushing force of the release rod that releases grain culm bundles is weakened, the stock resistance rod is still in the low speed position of the control lever. protrudes into the bundling release path for a short distance, reduces the resistance from the stock resistance rod, improves the separation of the grain culm bundle from the stock resistance rod at the time of release, extends the release distance, and falls near the traveling wheel position, It can prevent being trampled by running wheels.

Conversely, if the engine speed becomes high and the extrusion force for pushing out the grain culm bundles of the release rod that releases the grain culm bundles becomes stronger, the control lever that controls the engine speed can be used to control the engine speed. At the high speed position of the lever, the stock resistance rod protrudes into the bundle release path for a long time, and by utilizing the fact that the resistance due to the stock resistance rod increases, it is possible to limit the release distance of the grain culm bundle.

Therefore, the ejected grain culm bundles are always ejected in an orderly manner at a substantially constant position regardless of the engine speed.
