Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine harvester, and more specifically, a culm transfer device 25 having two upper and lower culm paths parallel to the transfer direction is provided at the rear of the threshing device 1, and a lower A culm cutting device 5 is disposed at the end of the culm path, and the culm cutting device 5
On the rear side, there is a binding device 1 in which the binding passage is made to run approximately along the upper culm route and close to the end of the upper culm route.
The present invention relates to a combine harvester characterized in that the culm No. 3 is arranged with a step difference upwardly, and the culm is selectively attached to one of the two upper and lower culm routes so as to be freely conveyable.

Conventionally, a combine harvester is provided with a culm cutting device and a tying device behind a threshing device, and the culm is selectively fed to either of these devices to cut or bind the culm. (Utility Model Application Publication No. 49-135364).

However, in this type of conventional combine harvester, no consideration is given to feeding the waste culm accurately into the binding path of the binding device without disturbing it, and the feeding of the waste culm to the binding device is not carried out smoothly. It was something.

Further, no consideration was given to making the installation of the culm cutting device and the binding device more compact, and because both devices were installed, the entire machine became bulky.

This invention was devised in view of the above-mentioned problems, and when a tying device and a culm cutting device are installed on a combine harvester at the same time, it is possible to accurately feed the culm to the tying device, and further, To provide a combine harvester that can be installed extremely compactly.

Hereinafter, one embodiment of the present invention will be described in detail based on the accompanying drawings.

In the figure, reference numeral 1 denotes a threshing device mounted on a traveling device 3 of a combine harvester, which threshes the husk harvested by a cutting section (not shown) provided in the front.

Reference numeral 5 denotes a shedding culm cutting device fixedly provided at the rear of the threshing device 1, in which a plurality of cutters 7 and rotors 9 that rotate relative to each other are arranged in parallel, and the shedding culms scraped by the rotor 9 are cut by the cutter 7. It is to be dropped onto the ground from the discharge port 11 at the bottom.

Reference numeral 13 denotes a binding device fixedly provided at the rear of the culm cutting device 5, which binds the culms and releases them onto the ground.

Reference numeral 15 indicates a packer for pushing the culm into the binding part 17; 19 indicates a T-protrusion that senses the pressure of the culm pushed into the binding part 17 and activates the binding mechanism; 21 indicates a binding string (not shown) for pushing the culm around the culm. The needle 23 is a discharge rod for discharging the bundled bundles of culms.

25 is a culm cutting device 5 which cuts the culm discharged from the threshing device 1;
Alternatively, it is a conveying device for conveying to the binding device 13, and is configured as follows.

That is, 27.29 is a drive pulley provided close to the end of the threshing device 1 and the front end of the binding device 13, respectively;
A driven pulley, 31 is a driving pulley 27, a conveyor belt that rotates around the driven pulley 29, 33 is a pulley 37 fixed to a drive shaft 35, and a driving boo IJ-27.
This is a belt that transmits power by passing around the pulley 38 that rotates integrally with the pulley 38.

The conveyor belt 31 is configured to be able to rotate in the direction of arrow A in FIG. 1 or in the opposite direction to arrow A in FIG. 1 by switching the rotation of the drive shaft 35 between forward and reverse directions.

Reference numeral 39 indicates an upper guide rod extending between the threshing device 1 and the tying device 13 near the upper side of the conveyor belt 31, and 41 an upper guide rod extending between the threshing device 1 and the culm cutting device 5 adjacent to the lower side of the conveyor belt 31. This is the lower guide rod extending between the

In this way, the culm transfer device 25 is provided with two upper and lower culm paths parallel to the transfer direction.

The culm cutting device 5 is disposed at the end of the culm path below the culm conveying device 25.

The binding device 13 is arranged so that its binding path is substantially along the upper culm path of the culm conveying device 25 and approaches the terminal end of the upper culm path, so that the binding path is connected to the rear side of the culm cutting device 5. It is arranged with a step upwards.

Therefore, the binding passage of the binding device 13 is directly and substantially linearly continuous with the upper culm path, and the binding device 13 itself has a higher ground clearance than the culm cutting device 5.

In the above configuration, when cutting the culm, when the drive shaft 35 is rotated forward and the conveyor belt 31 is driven in the direction of arrow A in FIG. 1, the culm threshed by the threshing device 1 is , is guided and conveyed to the lower guide rod 41 by the conveyor belt 31, falls into the culm cutting device 5, is screwed into the rotor 9, is shredded by the cutter 7, and is dropped to the ground from the lower discharge port 11. Ru.

In addition, when tying the waste culms, the drive shaft 35 is reversely rotated to rotate the conveyor belt 31 in the direction opposite to arrow A in FIG. are guided by the upper guide rod 39 and conveyed, fed into the binding device 13, bound in the binding section 17, and discharged to the ground by the discharge rod 23.

When the culm is fed from the culm path on the upper side of the culm transfer device 25 to the binding path of the binding device 13, the culm path and the binding path are directly continuous in a substantially straight line. The feeding of the waste culm is carried out accurately without any disturbance.

Since this invention has the configuration described in the claims,
This provides the following effects.

(a) Since the bundling passage is close to and along the culm path, when the culm is fed to the bundling device, the culm is fed directly into the bundling passage in a substantially straight line, and is not discharged. The culm is fed accurately without being disturbed.

Therefore, accurate binding can be expected.

(b) A culm cutting device is installed at the end of the lower culm path of two parallel upper and lower culm paths, and a binding path of a binding device is installed behind the culm cutting device. The two culm routes are arranged in a compact manner, and the distance between the culm transfer device, binding device, and cutting device is reduced. Combined with the fact that there is no wasted space at all, the culm cutting device and the binding device can be installed extremely compactly.

It should be noted that the present invention is not limited to the above-described embodiments, and may be implemented in other forms than the above-described embodiments.

Further, the numerals added for convenience in the claims do not limit the technical scope of the invention.
