Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is characterized in that a mowing unit is arranged so as to be movable up and down with respect to a position in parallel with a driving unit arranged at a front part of a vehicle body, Regarding the combine that the threshing device is located in,
More specifically, the present invention relates to a technique for preventing scattering of dust generated at the reaper.

[Conventional technology]

Conventionally, in the combine configured as described at the beginning, as a technique for preventing the scattering of dust generated in the cutting section, there is one shown in Japanese Utility Model Laid-Open No. 56-131730, and in this conventional example. A first cover attached to the mowing part and a second cover supported by a rail on the side of the mowing part so that it can slide back and forth with respect to the first cover constitute a dust-proof cover to prevent scattering of dust. It has become.

[Problems to be solved by the device]

In addition, considering the work form of the combine, the work of the combine involves the form of performing harvesting by running the car body in the field, and the work of the combine artificially with respect to the transfer device of the mowing unit with the car body stopped. A form of supplying shell culm bundle (so-called,
Since there are two types, the manual cutting work), in the above-mentioned reference, the manual cutting work can be performed by moving the second cover.

However, in the above-mentioned conventional example, the rear length of the rail supporting the second cover is limited so as not to hinder the hand-drawing work. Therefore, during the harvesting work performed by running the vehicle body, the second cover is the rear end part of the rail. It is only supported by and may become unstable and cause vibration.

The purpose of the present invention is to harvest the vehicle by running the vehicle,
Prevents scattering of dust in the mowing section without causing inconvenience such as vibration, and also greatly opens it during manual cutting work,
The point is to reasonably construct a dustproof structure that enables easy work.

[Means for Solving the Problems]

The feature of the present invention is that, as described at the beginning, in the combine in which the threshing device is arranged behind the reaping unit that can be moved up and down with respect to the position parallel to the driving unit, the combiner is operated in front of the threshing device. A frame rod that is swingably supported around a lateral axis is provided on the side that is eccentric to the portion in a posture that extends upward, and that the frame rod is laterally oriented with respect to the upper end of the frame rod. The dustproof cover is pivotally supported so as to be swingable, and the front part is supported so as to be movable back and forth with respect to the mowing section. The action and effect thereof are as follows.

[Action]

According to the above feature, since the rear end of the dust cover is supported by the frame rod and the front end is supported by the mowing part, the front and rear positions are fixed in the closed posture, and the posture is stable, and the rear end of the dust cover is rocked. Since it is pivotally supported with respect to the upper end of the dynamic frame rod, it enables opening and closing in a state where rattling is unlikely to occur, compared to the conventional example in which the dust-proof cover is guided by rails. Since the frame rod is swung when it is opened, it can be moved in a sliding manner as a whole without losing the posture of the dustproof cover. Further, since the frame rod is arranged on the side of the operating portion, the frame rod does not prevent the manual work when the dustproof cover is opened.

In other words, although there is a space where it is difficult to arrange the members above the transport system of the cutting culm that is formed between the mowing unit and the threshing device, avoid this transport system and shift it to the side of the operating unit and shake it. By arranging a movable frame rod and pivoting the dust cover on the upper end of this frame rod, the rear end of the dust cover can be stably supported at a position above the transfer system of the cutting shell and the dust cover can be supported when it is opened. The cover can be opened slidingly to allow manual removal work.

[Effect of device]

Therefore, the dust cover is supported to prevent the dust from scattering at the mowing part in a state where vibration is unlikely to occur during the harvesting work performed while the car body is traveling, and the dust-proof structure allows the work to be smoothly opened widely to facilitate the work during the manual cutting work. Was constructed.

〔Example〕

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

As shown in FIG. 4, a driver unit including a driver's seat (3), a plurality of operating levers (4), etc. on the front right side of a vehicle body (2) having a pair of left and right crawler traveling devices (1). (A) is arranged, and a reaping section (B) which moves up and down by swinging around a pivot axis (P) set in a lateral direction is arranged at a position parallel to the left side of the operating section (A). Is
A threshing device (5) is arranged behind the reaping section (B) to form a combine.

As shown in the figure, the mowing part (B) is composed of a plurality of sward plates (6)
..., a plurality of raising devices (7), a clipper-type mowing device (8), a conveying device (9) for feeding the mowing culms to the feed chain (5a) of the threshing device (5), and supporting the entire mowing section A support frame (10) that is swingably connected to the vehicle body (2) around the pivot shaft (P) and that transmits power to the reaper (B) by an internal transmission shaft (not shown). And the like, and the reaper (B) is driven up and down by a hydraulic cylinder (11).

In addition, this combine is provided with a dustproof structure for preventing scattering of dust generated in the cutting section (B) during work. This dustproof structure is, as shown in FIG. 2, the raising device (7) ...
It is composed of a resin dustproof plate (12) covering the upper part and the left outer side of the container, and a resin dustproof plate (13) covering the upper part of the transfer device (9). At times, it is configured so that the cutting culm can be released by moving it forward so that it can be easily supplied to the feed chain (5a).

That is, as shown in FIGS. 1 to 3, the frame rod (which is swingably supported around the lateral axis Q) on the side of the threshing device (5) which is eccentric to the operating part (A). 14) is provided so as to extend upward, and an upper end portion of the frame rod (14) and a support shaft (15) provided in a lateral position at the rear portion of the dust cover (13) form the support shaft ( The dustproof cover (13) is pivotally connected so that it can swing around the shaft core (R) that is coaxial with the shaft core (15).
