DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a harvester handling table.

Conventional technology and problems to be solved The harvester is generally equipped with a two-fold type stool on one side of the machine body (on the side of the grain culling plate of the thresher) on which grain bunches such as rice bunches are placed. Normally, while moving the rice rack (also called haze, haze etc.) where the rice culms, which have been cut and bound with a binder, etc., are naturally dried by hanging, etc., stop the aircraft near the rice rack and handle it. Threshing and bagging work are carried out with the platform extended laterally.

By the way, depending on where the rice rack is erected, there may be cases where the space in the field is small or there are obstacles, and it is not possible to fully extend the platform to the side of the machine. The work was done in a folded state, but when the handle was folded, there was a problem that the effective placement area of the grain culms at the corners was halved, which hindered efficient work.

Therefore, in the present invention, in a harvester in which grain culms placed on a handling table are sequentially supplied to a handling chamber to thresh, the handling table is vertically moved to the entrance plate side of the thresher. It is composed of a main handling table that is pivotally supported and an auxiliary handling table that is vertically displaceably fixed to the main handling table. The handling table is adjacent to the main handling table and the auxiliary handling table on substantially the same plane. It is intended to solve the above problems by arranging the work posture to be performed and the work posture in which the auxiliary handling table is located above the main handling table to be freely switchable.

Action Normally, work is performed with the handling table set in a single-step work posture in which the main handling table and the auxiliary handling table are adjacent to each other on a substantially same plane. If the working space is not enough due to the rice rack or obstacles, the auxiliary pedestal is vertically displaced to above the main pedestal.
Set the work posture in steps and perform the work.

Example 1 is a traveling machine body of a harvester supporting a crawler 2. An engine 4 and a driving operation section 5 are arranged on a machine body frame 3 of the traveling machine body 1 at a rear portion in a traveling direction of the machine body. Threshing machine 6 from the back side to the front of the machine
Is installed. 6a is a grain culm inlet of the thresher 6, 6b is a grain culm outlet, 7 is a fried cylinder, 8 is a paddle stand, 9 is a feed chain,
Reference numeral 10 is a straw carrier, 11 is a dust duct, 12 is a handle, and S is a clam grain collection bag detachably attached below the grain outlet 6b of the thresher 6.

By the way, the handling table 12 includes a main handling table 12a pivotally supported by a frame 14 detachably provided on the entrance plate 13 side of the threshing machine 6 through a support shaft 15 and a main handling table 12a. On the other hand, it is formed of an auxiliary pedestal 12b which is vertically movably and fixedly connected through a parallel link L, and is disposed at substantially the same height as a grain culm inlet provided at a relatively low position. The lower surface of the main handling table 12a is provided with a lower limit stopper 16 for maintaining the horizontal state by abutting against the frame 14 at the time of work, and the parallel link L is provided as shown in FIG. 1 and FIG. Rotating tip side of the handle 12a and the auxiliary handle 1
2b A pair of front and rear links 17 and 18 connecting the midway side, and a single link 19 connecting the base end side of the main handling table 12a and the base end side of the auxiliary handling table 12b. The pivot end of each link 17, 18, 19 is located at the main handling table 12a or the auxiliary handling table 12b.
It is fitted into the front and rear side plates from the outside and is prevented from coming off by the split pin 20. The links 17 and 18 are curved in a U-shape on the main handling table pivot side, and the curved portions 17a and 18a serve as a stopper for positioning. In addition, the main handling table 12a
When the auxiliary handling table 12b is rotated upward,
A hook 21 for sandwiching and locking 7a and 18a is fixedly provided. On the other hand, the corner of the auxiliary handling table 12b on the side of the operator M is a chamfered notch 22 as shown in FIG.

Now, at the time of work, the operator puts a bundle of grain culms placed on the handling table 12
Is fed from the grain culm entrance 6a into the handling room 23 via the feed chain 9 and is shredded by the handling barrel 24, and then sorted by the sorting section 25 below the handling chamber 23. Pressure air is sent from inside the cover 9'to the thresher inlet plate 13 and the grain culm inlet 6a
Part of the paddy is retained. That is, the baffle tube 23 in which the base end opening is made to face the starting end side chain 9a of the feed chain 9 with the 23a communicating with the inside of the feed chain cover 9'and the discharge port 23b is exposed on the inlet plate 13 And a small gear 28 which is engaged with a large gear 27 fixed on the shaft 26 of the chain wheel 9a so as to be engageable and disengageable, is swingably supported on the threshing machine 6 side through a support shaft 29 and has an upper end grip. A portion 30a is rotatably supported by a switching rod 30 protruding above the feed chain cover 9 ', and a compressed air fan 31 is fixed on a shaft 28' to which a small gear 28 is fixed. The compressed air generated by (3) is discharged to the grain culm entrance 6a through the air guide tube 23.

The width of the air guide tube 23 is gradually narrowed toward the tip so that the wind speed is increased in the air guide tube 23. On the other hand, the clam grain collecting bag S disposed on the grain culm outlet 6b side
Is a box-shaped box in which a cloth 34 is stretched around a rectangular rod-shaped frame 33 that is foldable around a pivot 32, and a pair of front and rear legs 35 projecting from one side of the frame 33 are fried. 7 and the threshing outlet side plate 36 are detachably fitted and supported by the seats 37 and 38 fixed to the threshing outlet side plate 36, respectively, and the support rod 40 fixed to the base 39 of the feed chain 9 can raise and lower the sensing rod 41 for detecting passage of the grain culm. The wire 43 is pivotally supported to connect the lower protruding portion 41a of the sensing rod 41 and the arm 42 projecting from the movable frame 33a of the recovery bag S with a wire 43, and the sensing rod 41 is pushed down by the supply culm during threshing work. When 43 is pulled against the ammunition 44 and the collection bag S is opened, and the grain culm is not acting on the sensing rod 41, the movable frame 33a is erected by the ammunition 44 and the collection bag S is opened at the grain culm outlet. 6b
It is designed to block the part. As a result, it is possible to prevent the clam particles from splashing out of the machine due to forgetting to put the recovery bag at the start of the work, and to eliminate the need for the exit scattering prevention curtain hanging from the exit cover 45 unlike the conventional case, and without removing the recovery bag S when storing the machine. It has the advantage of being compactly stored.

In the figure, 46 is an outer shell, 47 is Kara, 48 is a rocking sorter, 49
Is a handling drum pulley, 50 is a pinch rail, and a is a culm bundle after threshing.

In the above configuration, the traveling machine body 1 is stopped near a rice rack (not shown) or the like, and normally, as shown in FIG. 2, the main pedestal 12a and the auxiliary pedestal 12b are substantially flush with each other. Threshing work is performed by setting the work posture to the adjacent one step. At this time, the link
The curved portions 17a, 18a of 17, 18 contact the lower edge of the side plate of the main handling table 12a, and the main handling table 12a and the auxiliary handling table 12b are positioned and held on substantially the same plane. During work, the worker M is at the grain culvert entrance 12
Grain culm bundles on the stand 12 near the 6a are fed sequentially to the feed chain 9
In the case of a two-person work, an assistant (not shown) lowers the grain culm from the rice rack or the like and puts it on the handling table 12 at any time according to the work timing of the worker M. In addition, the pivot end of each link 17, 18, 19 is fitted into the front and rear side plates of the main handling table 12a or the auxiliary handling table 12b from the outside, and when the handling table 12 is arranged in one stage, each link 17, 18, 19 Does not project onto the pedestals 12a and 12b, the grain culms are not caught by the links 17, 18 and 19 and fall out, and the work is smoothly performed.

By the way, when the working space is not enough due to the obstacle B such as the rice rack, the auxiliary pedestal 12b is pivotally displaced above the main pedestal 12a as shown by the phantom line in FIG. Set the work posture in steps and perform the work. This makes the handling table 12
Since the amount of lateral overhanging is small, it is possible to cope with it even in a narrow space, and since the auxiliary pedestal 12b can be used as it is as a grain pedestal loading platform, the effective area of the pedestal 12 is not reduced and a large number of grain culm bundles can be loaded. You can work efficiently. Further, since the corners of the operator M side of the auxiliary pedestal 12b located above are chamfered notches 22, the auxiliary pedestal 12b
When lowering the grain culm on the 12b, the grain culm bundle can be easily taken, and the link on the front side when viewed from the operator M side in this two-stage posture of the handling stand
Since the number of the links 17 is one, and the link 17 is located outside the proper working position of the worker M, the link 17 does not interfere with the feeding of the grain culms. By the way, since the auxiliary pedestal 12b is not detachable and can be switched to a one-step or two-step posture with one touch, the working table can be set to either one step or two steps so that the work can be quickly started. .

Effect of the Invention As described above, in the present invention, in the harvester in which the grain culms placed on the handling table are sequentially supplied to the handling chamber to thresh, the handling table is vertically moved to the entrance plate side of the thresher. It is formed by a main handling table that is rotatably supported and an auxiliary handling table that is vertically movable and fixed to the main handling table, and the handling table is adjacent to the main handling table and the auxiliary handling table on substantially the same plane. Since the work posture and the work posture in which the auxiliary handling table is located above the main handling table can be switched freely, if the working space is not sufficient due to the rice rack etc., the handling table can be switched to two stages. Although it can handle a narrow space sufficiently, the grain space can be placed on the upper and lower pedestals by effectively utilizing the narrow space, so that the work efficiency can be further enhanced.
