Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, a mowing section is connected to a vehicle body at a position in parallel with a driving section arranged in a front portion of the vehicle body so that the mowing section is vertically movable. TECHNICAL FIELD The present invention relates to a combine in which a threshing device is arranged at the rear of the, and more specifically, to a technique for preventing scattering of dust generated at the cutting unit.

[Conventional technology]

Conventionally, as a technique for preventing dust generated at the harvesting part of a combine constructed as described in the introduction, there has been a method of actual development of Sho 56-131.
There is one disclosed in Japanese Patent No. 730, and in this reference, a mowing part is provided with a first cover attached to the mowing part and a second cover supported by a rail of the mowing part so as to be slidable with respect to the first cover. It is configured to cover the upper part of the portion and prevent scattering of dust.

[Problems to be solved by the invention]

In addition, regarding the work form in the combine, the work in the combine involves the form of performing harvesting by running the car body in the field, and the work performed by the harvesting unit while the car body is stopped. Since there are two types, that is, a form for supplying a grain culm bundle to the above (so-called manual handling work), in the above-mentioned reference, the manual handling work can also be performed by moving the second cover.

However, in the above-mentioned reference, the rear length of the rail supporting the second cover is limited so as not to hinder the manual handling work.
The cover is supported only at the rear end of the rail, which may cause instability and vibration.

The purpose of the present invention is to prevent dust from scattering at the cutting part during harvesting work by running the vehicle body, and to reasonably form a dust-proof structure that is opened widely for manual handling work to facilitate work. is there.

[Means for solving problems]

DISCLOSURE OF THE INVENTION The present invention is a combine harvester in which a mowing unit is connected to a vehicle body in a position parallel to a driving unit arranged in a front part of a vehicle body so as to be movable up and down, and a threshing device is arranged behind the mowing unit. A frame rod that is swingably supported around a lateral axis is provided in the front part of the device in a posture that extends forward at a position closer to the operating part above the mowing part, and protrudes upward at the mowing part side. The frame cover is provided, and the dust cover that covers the upper part between the threshing device and the mowing section is supported by the frame rod and the frame body, and the dust cover is supported on the frame rod while being supported by the frame body. It is characterized in that it is provided slidably in the front-back direction.

[Action]

Of the frame rod and frame body that supports the dustproof cover,
Since the frame rod pivotally attached to the threshing device on the machine side is provided close to the operating part and the frame body is provided on the mowing part side, when the dustproof cover is slid forward and opened, the mowing There is no obstruction between the section and the threshing device, and it is easy to perform manual handling work from the side of the machine.

Since the dustproof cover is supported on the threshing device side by the frame rod and the frame body on the reaping part side, the dustproof cover is stably supported at the front and rear positions even in the closed state by sliding backward during work traveling. It will not rattle like that.

Further, since the frame rod (14) is swingably supported with respect to the front part of the threshing device (3), when the cutting unit (B) is moved up and down, it is integrated with the frame rod (14). Further, since the dust cover (13) swings, it does not hinder the raising and lowering of the reaper (B).

[Effect of device]

Therefore, a dust-proof structure is formed that prevents dust from scattering at the mowing section while the dust-proof cover is stably supported during harvesting work performed while the car body is running, and that the work is opened widely to facilitate work. It was done.

As shown in the figure, the mowing unit (B) includes a plurality of weeding tools (6) ..., a plurality of raising devices (7) ..., a clipper-type mowing device (8), and mowed culms. The transmission frame (11) has a transmission frame (11) for transmitting power to the transfer device (10), the mowing device (8), the transfer device (10), etc., which are sent to the feed chain (3a) of the threshing device (3). The rear end of (11) is a lateral axis centered on the vehicle body (2).
(P) is swingably connected and a hydraulic cylinder (12) is provided between the transmission frame (11) and the front part of the vehicle body (2) to raise and lower the reaper (B). Is configured to do.

Also, with this combine, a dustproof cover is provided above the mowing part (B).
(13) is provided to prevent the dust generated in the reaping section (B) from entering the operating section (A).

That is, as shown in FIGS. 1 to 6, a horizontal shaft core is provided in the front part of the threshing device (3) on the side of the operating part (A) above the cutting part (B).
Around (Q), a frame rod (14) whose rear end is supported is arranged, and a front end of this frame rod (14) is supported by a support frame (15) erected on the transfer device (10). Is supported by a boss member (18) at the end of a rod (17) provided through a pair of brackets (16) and (16) in a loosely fitted state.
A boss member (19) is slidably fitted to the rear part of the lower surface of the dustproof cover (13) on the operation side of the dustproof cover (13), and a pair of left and right rails (20) formed on the lower surface of the dustproof cover (13). ), (20) by inserting rollers (21) formed at both ends of the rod (17), the dust cover (13) can be slid in the front-back direction, and the cutting section (B Since the frame rod (14) swings around the lateral axis (Q) when it is moved up and down, it is configured so as not to twist.

That is, the support frame (15), bracket (16), rod (1
The dustproof cover (13) is supported by the frame rod (14) and the frame body (F) including the roller 7 and the roller 21.
