Description

[Detailed description of the invention] The present invention relates to a reaping and binding machine (binder) that harvests crops such as rice and binds them in appropriate amounts. In a reaping binding machine having a reaping binding part disposed on the reaping binding part, a mudguard plate is provided between the running wheels and the reaping binding part to prevent mud splashed up from the traveling wheels from splashing onto the reaping binding part. On the other hand, the structure is simplified by attaching to this mudguard plate a string brake and a sagging prevention body for the binding string to the binding mechanism in the reaping binding section.

The present invention will be explained below with reference to the drawings.
In the figure, 1 shows a pair of left and right branching bodies 2 at the front.
2', a reaping binding section 6 consisting of a grain culm lifting mechanism 3, a reaping mechanism 4, a binding mechanism 5, etc., and an engine 7 at the rear.
A reaping and binding machine is shown in which a transmission case 10 is provided with a control handle 8 and a pair of left and right wheels 9, 9' in the middle part, and the binding mechanism 5 is mounted on the upper surface of the middle part. A cover 13 having a mounting portion 12 for the binding string coil 11 is attached.

The engine 7 is attached to the rear end of a cylindrical case 14 that extends rearward from the upper rear surface of the transmission case 10, and power from the engine 7 enters the transmission case 10 through a shaft 15 inside the cylindrical case 14. This drives both traveling wheels 9, 9'.

Further, the rear end of a pipe-shaped frame 16 extending diagonally downward in the front is attached to the upper front surface of the transmission case 10, and the binding mechanism 5 is attached to the front end of the frame 16, and the binding mechanism 5 is attached via a bracket 17. The grass cutting bodies 2, 2', a reaping mechanism 4, and a grain culm lifting mechanism 3 are attached. This pipe-shaped frame 1
6 includes an engine 7 in the transmission case 10.
A power transmission shaft 18 interlocked with is inserted, and the front end of the power transmission shaft 18 is connected to a vertical shaft 20 in a gear case 19 attached to the front end of the frame 16.
1 and 22, a crank 23 for driving the reaping mechanism 4 is fixed to the lower end of the vertical shaft 20, and a sprocket 24 fitted to the upper end of the vertical shaft 20
The power is transmitted to the binding mechanism 5 through a chain 27 wound between the sprocket 26 fitted on the input shaft 25 of the binding mechanism 5, and then to the output shaft 2 of the binding mechanism 5.
A chain 32 is wound between the sprocket 29 fitted to the grain culm lifting mechanism 3 and the sprocket 31 at the lower end of the vertical shaft 30 to the grain culm lifting mechanism 3, and the grain culm lifting mechanism A vertical shaft 31 to the culm lifting mechanism 3 is provided with raking wheels 33 , 33 configured to drive the mechanism 3 .

The upper wheel 33 of the two wheels 33 is close to the lower end of the gear case 34, and the lower end of the gear case 34 has a substantially fan-shaped winding prevention plate 3.
6 is provided.

A substantially vertical mudguard plate 3 extending in the vertical and horizontal directions is located between the transmission case 11 equipped with the running wheels 9, 9' and the reaping binding section 6.
7 is provided with its upper end attached to the cover 13 and its lower end attached to the pipe-shaped frame 16.
On the front side of the mudguard plate 37, that is, the surface on the side of the reaping binding unit 6, there is a string brake 4 for applying a brake to the string 40 that is being fed out from the string coil 11 and being supplied to the needle 39 in the binding mechanism 5.
1 and a spring 42 for preventing the string 40 from sagging.

Note that the top plate 43 and the vertical plate 4 of the cover 13
4 is provided with a hole 45 through which the string brake 41 and the slack prevention spring 42 can be accessed.

In this configuration, by moving the reaping and tying machine 1 forward while driving the reaping and tying section 6,
The grain culms to be planted in the field are first raised by the grain culm lifting mechanism 3 and harvested by the reaping mechanism 4, and then
It is sent to the binding mechanism 5, where it is bundled into an appropriate amount, and then tied at the base with a string 40, and then released to the side of the reaping and binding machine 1.

During the above-mentioned reaping binding work, the mud thrown up by the running wheels 9, 9' is blocked by the mudguard plate 37 provided between the running wheels 9, 9' and the reaping binding section 6, and Since there is no scattering on the reaping binding section 6, it is possible to reliably prevent various problems such as a decrease in durability and bundling errors caused by mud splashed up by the running wheels 9 and 9' scattering on the reaping binding section 6. Moreover, by providing a string brake 41 and a spring 42 for preventing sagging of the string 40 supplied to the tying mechanism 5 in the reaping binding section 6 on the front surface of this mudguard plate 37, this string brake 41 and a spring 42 for preventing sagging are provided. The mud splashed up by the running wheels 9, 9' does not adhere to the springs 42, and the string 40 can be smoothly supplied to the binding mechanism 5.

Furthermore, by providing the string brake 41 and the slack prevention spring 42 on the mudguard plate 37, the mudguard plate 37 can also be used as a bracket for the cord brake 41 and the slack prevention spring 42.
The structure is simpler than when these are mounted using separate brackets, and the mounting space can be reduced.

Therefore, according to the present invention, it is possible to prevent the adverse effects of mud thrown up from the running wheels on the reaping binding portion, and also to simplify and downsize the structure.
