Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a vertically-rotating type forcible stem forcibly in front of a laterally-turning type forage-causing device which is located on the most uncut side during standard cutting. The present invention relates to a mowing and harvesting machine provided with a grass device and having a lateral outer rear part of the stem-and-culm raising device covered with a cover.

[Conventional technology]

In the above-mentioned reaper harvesting machine, conventionally, for example, the actual exploitation Sho 57-11
As shown in Japanese Patent No. 9652, a transmission case for raising power from a transmission system of a raising device to a vertically-rotating type stem culm forced weeding device is raised from the uncut side of the grain stalk to the lateral outside of the device. There was a flat cover that was placed outside the cover to project outward from the cover.

[Problems to be solved by the device]

The transmission case needs to be attached to the outside of the cover as a position to avoid interference with various devices for raising and harvesting harvested culm, but originally, the stem-culm forced weeding device is used for grain. In the case where the culm is heavily collapsed and the transmission case, which is usually made by combining two cases made of sheet metal, is projected outward from the cover, as in the above-mentioned reference, for example, the uncut side grain culm is the machine body. In the case where the grain culm is leaning to the side, the tip side of the grain culm may be squeezed by being caught by the edge portion of the transmission case, and shedding may occur.

The present invention has been made in view of the above circumstances, and an object thereof is to improve the structure of a mounting portion of a transmission case and eliminate the above-mentioned problems.

[Means for Solving the Problems]

The characteristic configuration of the present invention is that a transmission case for transmitting power from the transmission system to the raising device to the stem-culm forced weeding device is provided along the outside of the upper half of the cover, and under the cover. It is a point that the half portion is provided in a state of bulging outward from the upper half portion.

[Action]

According to the above configuration, since the lower half portion of the cover is bulged outward than the upper half portion, uncut grain culm is regulated from falling into the fuselage side by the lower half portion, even if: Even if the grain culm falls down toward the machine body, it becomes difficult to reach the transmission case attached to the upper half portion.
Further, even if the grain culm touches the transmission case, the lower part of the grain culm is received by the lower half part of the cover, so that it is not strongly rubbed against the transmission case.

Also, since the front half of the cover is bulged to widen the pocket of the front transport portion, the cuttings and straw scraps generated by the raising device and the stem-culm forced weeding device are cut grain culm. It easily separates from the inside of the cover and falls into the field scene.

[Effect of device]

Therefore, according to the present invention, shedding of uncut grain culms due to interference between the uncut grain culms and the transmission case can be suppressed. In addition, the deterioration of the conveyance performance due to the clogging of straw chips and the like in the front conveyance section surrounded by the lower half of the cover is less likely to occur.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a combine according to the present invention. This combine is configured by vertically connecting a mowing section (3) to a front part of a machine body having a pair of left and right crawler traveling devices (2), and a threshing device (4) at the rear part of the machine body (1). ing.

And, a weeding rod (5) is provided over almost the entire lateral surface of the machine body on the uncut side.

As shown in FIG. 2, this branch rod (5) is composed of a front part rod (5A) and a rear part rod (5B), and these front and rear part rods (5A), (5B) In addition to being movably connected,
The front part grass rod (5A) is horizontally pivoted to the uncut side weeding tool (7), and the rear part grass rod (5B) is horizontally swingable to the rear part of the threshing device (4), and the rear part grass The rod (5B) is connected to a support frame (6) that can move in and out in the lateral direction of the machine body. Further, a plate body (8) for expanding and reinforcing the grain culm guide surface is attached to the front part grass rod (5A).

As shown in FIG. 2 and FIG. 3, the reaper (3) together with the weeding tool (7), the stem-culm forced weeding device (9) for weeding the lodging grain culm, raises the cultivated grain culm. A raising device (10), a harvesting device (11) for cutting the grain culms after the raising, a vertical transport device (12) for transporting the harvested grain culms to the rear threshing device (4), and a raising device (10 ) And a vertical transfer device (12), etc., each having a transmission frame (13) for transmitting power to the vertical transfer device (12).
Is covered with a cover (14), the rear end of the transmission frame (13) is swingably connected to the machine body about a lateral axis, and between the transmission frame (13) and the machine body. It is designed to be lifted and lowered by a hydraulic cylinder (15) provided.

In addition, in this combine, the weeding tool (7), the stem culm forced weeding device (9), the raising device (10), etc., located in front of the transmission frame (13) are configured to be slidable left and right. (The slide movement structure is not detailed). Then, as shown in FIG. 4 and FIG. 5, when the reaping part (3) is laterally slid to cut the ridges in the wetland, the mud soil is prevented from riding on the concrete ridges and walking on the ridges. For simplification, two scrapers (17) and (17) are provided by stacking two scrapers (17) via a support arm (16) mounted obliquely rearward from the rear portion of the body frame (1) on the cut side. These scrapers (17), (17) are formed with a plurality of slits (17a) to improve the familiarity with the upper surface of the ridge, and each scraper (17) is changed in the phase of the slit (17a). By attaching it to the support arm (16), the mud on the upper surface of the ridge can be scraped off.

As shown in FIG. 1, the stem-culm forced weeding device (9) is connected to the raising device (10) by a transmission case (18) arranged outside the upper half part (14A) of the cover (14). Power is transmitted from the drive system. This transmission case (18) is constructed by housing a chain transmission mechanism (19) in a case body (20) in which a left and right case made of sheet metal is fastened with bolts. The lower half portion (14B) of the cover (14) is bulged outward to near the outer surface of the transmission case (18) as shown in FIG.

Incidentally, as shown in FIG. 6, the front part of the sward rod (5) is composed of two front part rods (5A) and (5A).
May be reinforced and the weeding performance may be improved.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
