Description

[Detailed Description of the Invention] The present invention relates to a reaping machine, and its purpose is to be able to smoothly guide uncut planted stem culms that fall down from the front side of the pulling device to the outer rear without damaging them, and to To avoid noise caused by lifting claws and a lifting case when lifting a planted stem culm, and to avoid adverse effects caused by straw waste entering the case.

Embodiments of the present invention will be described in detail below based on the drawings.

At the front of the machine body equipped with the crawler traveling device 1, the pre-processing section 5 consisting of the planted culm lifting device 2, the reaping device 3, and the cut culm vertical conveyance device 4 can be rotated up and down around the horizontal axis. At the rear of the machine, a threshing device 6 and a feed chain 7 attached thereto,
The machine is configured to thresh the harvested husk culm from the vertical conveyance device 4 and pack the threshed grains into bags, thereby configuring a combine harvester for reaping and threshing the husk culm without running the machine. .

A stem culm raking and conveying device 8 is provided between the pulling device 2 and the vertical conveying device 4, and acts on the base of the raised stem culm to ensure that it is raked into the reaping device 3 and harvested. The structure is such that the stem culm is reliably raked and conveyed toward the vertical conveyance device 4.

To configure the scraping and conveying device 8, a gear 1 is mounted on a base 9.
0 internally and a gear box 12 bearing a drive shaft 11 is attached, and a star wheel 13 for scraping the stem culm and a wheel 15 for winding and driving an endless band with scraping protrusions are wound around the drive shaft 11 in order to integrally rotate. It is a provision.

Furthermore, a driven shaft 1B has a star wheel 16 fixed to the base 9 that meshes with the star wheel 13, and a wheel 17 for winding and driving the endless band 14 with scraping protrusions fixed thereto.
The bearing is.

Further, an idler wheel 2 around which the endless belt with projections 14.14 is wound.
1.21 is supported on the base 9.

In other words, the drive shaft 11 and the driven shaft 1B are connected to the board 9.
This pre-assembled raking and conveying device 8 is configured to be assembled as a unit with the reaping case 19 by meshing the gears, and the raking and conveying device 8
The structure is designed to facilitate and speed up assembly in a separate process and to improve assembly accuracy.

The lateral outer end of the front case 20a of the lifting case 20 on the outermost side (uncut side) of the lifting device 2 is extended rearward, and this extended case portion is used as the side cover 20.
The front case 20a and the side cover 20b are integrated to simplify the structure and manufacture.

A gap A is formed on the side cover 20b side between the front case 20a and the rear case 20C corresponding thereto, and a gap A is formed between the outer end of the rear case 20C and the side cover 20b. A gap B is also formed in between, and the side cover 20b suppresses the accidental standing up of the pulling claw 2a in the retracted position, and also allows the hitting sound when the claw is retracted to escape from the gap A. This structure is designed to avoid noise generation due to resonance caused by the mating case.

The side cover 20b is provided with a headlamp 22, and the headlamp 22 is directed along a continuous stalk guide surface formed by the front case 20a and the side cover 20b. It is preferable that the stem be provided so as to guide the stem culm smoothly.

In summary, in the present invention, the outer end of the part of the front case of the hoisting device located at the outermost part of the aircraft body extends rearward in a continuous manner, and the extended part forms a side cover. Since the boundary between the outer edge of the front case and the front edge of the side cover can be made into a continuous surface with no steps or gaps caused by seams, it is possible to prevent the unloading device from falling in front of the lifting device. The front case and the side cover that follows allow the cut and planted stem culms to be guided smoothly in a continuous manner without causing problems such as getting caught, and prevents damage to the uncut and planted stem culms or shedding. Not only is it possible to do good weeding with less risk of causing problems, but also straw waste, dirt, etc. attached to the uncut, planted stem culms, etc. will be lifted up during this weeding and invade the case. There are no drawbacks, and there is an advantage that there is less risk of causing trouble in the operation of various mechanisms installed in the lifting case.

Furthermore, by extending the outer end of the front case rearward to form a side cover, it is possible to completely prevent uncut planted stem culms from entering the case. The gap formed between the front case and the rear case on the side cover side, and the gap formed between the outer end of the rear case and the side cover can also be formed sufficiently large. As a result, the sound of the lifting claw when it is retracted and the noise generated by the operation of the driving parts such as the lifting chain can easily escape from the case through this wide gap. Unlike the conventional type, it does not have the disadvantage of being amplified many times due to resonance, allowing for extremely quiet work, and it also eliminates straw and dirt that enters from the opening on the pulling path side. It is easily discharged from the case through a wide gap, which has the advantage of further reducing the possibility of operational troubles of the drive mechanism inside the case.
