Abstract

PURPOSE:To enable to reduce the occupying area of a sun visor on the distribution of reaped products by attaching the sun visor to supporting frames in a state capable of being rotated or fixed about a longitudinally directed supporting shaft disposed on the supporting frame for supporting the sun visor on the inner side of the frame from the transverse center of the sun visor. CONSTITUTION:A reaping section and an operating section 9 are disposed on one lateral side of a reaping harvester and the other side, respectively, and a sun visor 17 is positioned above the operating section 9. The sun visor 17 is attached to supporting frames 18A and 18B in a state capable of being rotated or fixed about a longitudinally directed supporting shaft disposed on the supporting frame positioned on the inner side of the frame from the transverse center of the sun visor 17. The occupying area of the sun visor can be reduced on the distribution of the reaped products, and the operability of the sun visor can be improved because the larger is sliding transfer of the sun visor than that of a sliding type sun visor is not required. The structure of the harvester in which the rotating and supporting point is deviated on the transverse position from the transverse center of the sun visor permits to reduce the projected portions of the harvester in the upward direction and withdraw the sun visor within the frame without changing the position of the sun visor in the height direction thereof.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting and harvesting machine for, for example, straw grass, etc., and more specifically, it has a cutting section on one side of the front side and a side opposite to the side where the cutting section is present. The present invention relates to a reaping harvester which is provided with a control section and has an awning located above the control section.

[Conventional technology]

Traditionally, the sunshade has been fixed to the front support frame.

[Problem to be solved by the invention]

When such a fixed awning is applied to the reaping and harvesting machine, since the control section is provided offset to the side, the awning has a thick surface to increase its effectiveness. Part of the sunshade sometimes protruded beyond the width of the aircraft.

Therefore, for example, the protruding part of the awning becomes an obstacle during the distribution stage of shipping from the factory to each store, etc., and there is a limit to the number of vehicles that can be loaded per - truck, reducing distribution efficiency.

An object of the present invention is to provide a structure that is advantageous for logistics by devising a structure for attaching an awning to a support frame.

[Means to solve the problem]

The characteristic configuration of the present invention is that the sunshade is attached to a support frame that supports the sunshade inward from the center of the width of the sunshade, so that it can be swung and fixed around a longitudinal support shaft provided on the support frame. Its functions and effects are as follows.

[For production]

In other words, during reaping work, the awning is stretched in a predetermined position (for example, in a horizontal position), but during logistics, etc., the awning is swung around the longitudinal support shaft, and the part that protrudes from the machine width is moved within the machine width. to reduce the area it occupies.

Moreover, since the mounting swing fulcrum of the sunshade relative to the longitudinal support shaft of the support frame is located inward of the body from the center of its width, the length from the swing fulcrum of the sunshade to the outer edge of the machine is Since the length is longer than the length from the swing fulcrum to the inner side edge of the body, the outer side edge of the body is swung downward compared to when the swing fulcrum is at the center of the width of the sunshade. Even with the same swing angle, the amount of retraction toward the inside of the body can be increased, and the amount of protrusion in the height direction can be reduced.

[Effects of the invention] As a result, by configuring the sunshade in a swinging type, the area occupied during distribution can be reduced, and operability can be improved by not having to slide a large sunshade compared to a sliding type. , and the structure in which the swing support point is laterally offset from the center of the width of the sunshade allows the amount of protrusion in the height direction to be reduced, and the slide allows the sunshade to be retired within the width of the aircraft without fluctuation in the height direction. It is possible to create an effect similar to the formula structure.

Next, the first switching mechanism (A) will be explained.

As shown in FIGS. 8 and 9, a notch is provided on the upper surface of the rear end of the left and right channel-shaped fixed guide frames (24), (24) to allow the transfer roller (22) to be pulled out, A sliding pressing member (25) that slides left and right to open and close this notch is provided.
) A guide rod (41>) is provided to protrude laterally from the traveling body (4) so as to prevent the traveling body (4) from being lifted from the upper surface while allowing sliding of the traveling body (4).

The traveling body (4) is located on the rear side of the guide rod (41).
A boss (42) is fixed horizontally through the
A movable rod (43) is a pivot support that can move in and out of the movable rod (42), and a fulcrum rod (44) is located further rearward than the movable rod (43) and protrudes inward from the traveling body (4). ), and bell crank-shaped connectors (45A), (45B) are supported horizontally swingably on the movable rod (43). The above configuration is provided on both the left and right sides, and the left and right connectors (45A) and (45B) are connected to each other at the center by a pin (46). Also, this connector (45A)

3) is connected.

Therefore, as shown in the figure, when the operating lever (48) is operated, the proximal arm (47) horizontally swings to pull the movable rod (43) outward. Then, the connectors (45A) and (45B) horizontally swing around the mounting fulcrum on the fulcrum rod (44), and eventually the left and right movable rods (43)
is actuated, the sliding holding member (25) moves outward to open the notch.

When the operating lever (48) is operated in the opposite direction, the sliding pressing member (25) closes the notch. A pin (46) connecting the left and right connectors (45A), (45B) is fixed to one connector (45A), and a pin (46) connecting the left and right connectors (45A), (45B) is fixed to one connector (45A).

), move backward inside (24) and lift link (19)
is in a stretched state. Then, as shown in FIG. 6, the loading platform (15) moves up and down in parallel.

On the other hand, as shown in FIG. 7, when the sliding presser member (25) is slid to open the notch of the guide frame (24) and the cylinder (14) is extended,
The lifting link mechanism (19) swings upward together with the loading platform (15) in a contracted state.

Next, a handrail-like receiving rod (37) is provided on the rear surface of the loading platform (15) as a side wall, and this receiving rod (37)
In addition to blocking the accumulated crops, the loading table (15
) automatically becomes open in the dump state.

As shown in FIGS. 11 and 12, a round bar-shaped guide (2C) is inserted so as to fill the gap between the lateral end of the back cover (2A) for the lifting device and the moving path of the lifting claw (2B). )
This serves to prevent the regular grass that has come off the lifting claw from getting stuck in this gap and being cut or damaged before being cut. In addition, this round bar-shaped guide (2C) is a cover for the lifting device (2A).
) It is installed so as to bypass the lower end of the case, forming a gap that allows debris accumulated in the case to fall and be released.

Next, the horizontal axis (X) structure of the reaping frame (33) will be explained. As shown in Figure 1O, the traveling aircraft (4
A vertical position adjustment mechanism (26) of the reaping frame (33) with respect to the traveling body (4) is provided at the left and right lateral front ends of the reaping frame (33). This vertical position adjustment mechanism (26) is held between a pair of left and right plate-shaped brackets (27), (27), and is fixed with a bolt (30) so as to be movable up and down. The transmission shaft boss part (28
), the proximal end (33A) of the reaping frame (33) is externally fitted to the boss (28) so as to be able to swing up and down around the boss axis, and the reaping frame (33) can be moved up and down. It consists of an adjustment bolt (29) that allows the Therefore, if you loosen the bolt (30) and operate the adjustment bolt (29),
The vertical height of the reaping frame (33) can be changed, for example,
In soft fields where the crawler traveling device (11) sinks, the mowing height cannot be changed by simply raising and swinging the reaping frame (33). If the mowing height is raised to 1, the ground contact portion of the reaping frame (33) will not sink into the field surface without changing the cutting height.

Further, as shown in Fig. 1θ, a spring (32) is interposed between the piston rod and the cylinder case of the lifting cylinder (31) that swings and drives the reaping frame (33),
A configuration is adopted to reduce the ground pressure of the reaping frame (33).

Next, the sunshade (17) installed above the control section (9) will be explained. As shown in FIGS. 1 to 3, pipe support frames (18A) are installed in front and behind the control section (9),
(18B) is erected, and the sunshade consists of a cover (34) and a framework frame (35) to which this cover (34) is attached to the front and rear pipe support frames (18A) and (18B). The main body of the sunshade is detachable. The framework frame (35) has a substantially rectangular shape, and is constructed by installing a center pipe frame (36) at a position offset in the lateral direction from the width center. As shown in FIG. 2, the front pipe support frame (18A) has its upper end bent and extends inwardly into the fuselage, and a front support part (38) of the frame frame (35) is provided at its tip. . On the other hand, the rear pipe support frame (18B) extends linearly upward, and is provided with a rear support portion (39) of the frame frame (35) at its upper end. These front and rear support parts (38
), (39), the center pipe frame (3
6), the main body of the awning is supported by the pipe support frames (18A) and (18B), and the rear support part (39) is penetrated from the rear support part (39) to the center pipe frame ( When the long pole (40) that passes through the inside of the front support part (36) and screws into the threaded part of the front support part (38) is tightened, the part of the front and rear support part (39) where the center pipe frame (36) is fitted Since it has a tapered shape, the attitude of the center pipe frame (36) and thus the sunshade (17) is fixed. Therefore, the awning can be set and fixed at any angle by tightening and fixing only the long bolts (40). Moreover, since the longitudinal swing fulcrum axis is the center pipe frame (36) axis and is located toward the inside of the fuselage, the side end of the sunshade on the side of the exterior of the fuselage may be retired to the inside of the fuselage. There is no need to make a large swing, and the amount of upward protrusion of the lateral end on the inward side of the body can also be suppressed. Moreover, as shown in FIG. 1, when it is reversed by 180 degrees, it can be accommodated within the width of the fuselage and the height can also be reduced. As shown in Fig. 3, the framework frame (35) to which the cover (34) is attached to the sunshade is provided with a pair of left and right mounting and fixing brackets (41A) and (41B).
7) in the normal installation state (solid line state in Figure 1), the bracket (on the right side of the center pipe frame (36)
41A) is the mounting screw (1) of the front pipe frame (18A).
8a) to establish the support structure of the sunshade (17), and when it is turned over by 1&0° (virtual line state in Figure 1), the right side bracket (41B) is inserted into the mounting screw (18a) from below. ) is inserted and engaged and tightened and fixed. Therefore, in the normal installation state, the framework frame (35) can be received at the upper horizontal portion of the front pipe frame (18A), and the center of gravity of the sunshade (17) itself is lower than the center pipe frame (36) at this upper end. Since it is located on the horizontal part side, the long bolt (40)
Even if the tightening of the sunshade becomes loose, the main body of the sunshade will not change its position.
