Description

[Detailed explanation of the invention] Conventionally, combine harvesters did not have a suitable body support device for the auxiliary worker who rode on the machine and replaced the paddy bag in the rip-off device, which caused fatigue if the worker continued to work for a long time under strong vibrations. It was extremely dangerous to work on a tilting aircraft with just a back support.

This invention is an auxiliary aid for combine harvesters that allows auxiliary workers to continue working for long periods of time with extremely little fatigue and to continue working safely, and that hanging paddy bags does not become an obstacle when lowering or driving. It is intended to provide a seat for the worker, and a tearing device for storing threshed grain is provided behind the seat on the front side of the machine, and a substantially horizontal seat facing the tearing device from the outside is provided. A pair of upper and lower support frames 8a and 8b are attached to the tip of the arm rod 12, a back support 9 is attached to the upper support frame 8a, and a buttocks support 10 is attached to the lower support frame 8b, The base of the arm rod 12 is attached to the machine frame on the back of the seat so that it can be locked in both directions so that the back rest and butt rest can be switched between a used state and a non-used state. .

One embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a paddy bag pipe deck installed at the rear of the operator's seat, and a support frame is provided below the distribution pipe 5 of the grain lifting machine 4 of the threshing machine 3. A plurality of sets of tear rods 7, 7, . . . are provided to protrude from 6 and project outward.

Reference numeral 8 denotes a frame body made by bending a pipe into a rectangular shape, and in the example shown in FIGS. 1 and 2, a back support 9 is provided on the upper support frame 8a, and a butt support tool is provided on the lower support frame 8b. 10 is the fixture 1
The back support 9 and the buttocks support 10 are integrally formed of a flexible material such as synthetic resin.

Further, as shown in FIG. 1, the base of the frame body base is integrally fixed to the tip of the arm rod 12 which is substantially perpendicular to the longitudinal direction of the frame base, and the base of the arm rod 12 is attached to the frame that constitutes the seat 2. It is rotatably supported on the body by a shaft 13, and the shaft 13 has a plurality of holes 14 bored vertically at appropriate intervals in the frame of the seat 2.
14..., and the pin 15 that supports the tip of the arm rod 12 also has a plurality of holes 16 and 16 bored in the frame of the seat 2 at appropriate intervals in the vertical direction. It is removably attached to...

Note that FIG. 3 shows an example in which the bearing portion is integrally formed with the back rest 9 and the butt rest 10.

Next, another embodiment of the present invention will be explained with reference to FIGS. 4 and 5. The back support 9 and the buttocks support 1o are constructed separately,
The back support 9 is constructed of a plate-like body as in the previous example, and is movable in the length direction of the support frame 8a.

The buttock support 10 is attached to a U-shaped lower support frame 8b' made of net so as to be movable in its length direction.

In the above-mentioned apparatus, the husk harvested by a reaping device (not shown) is threshed by a threshing device 3, and then the sorted paddy is fried by a grain hoist 4, which is divided into three parts by a distribution tube 5. It flows out.

At the bottom of each branch pipe of the distribution pipe 5, there are tear rods 7.7 and 7.
Since the paddy bags 17.17... suspended in ... are open, the above-mentioned paddy that has flowed out is placed in the paddy bags 17.17 and ..., respectively.
... is filled.

When the paddy bags 17, 17 are filled with a predetermined amount of paddy, the auxiliary worker tears the filled paddy bags 17 into pieces 7, 7.
At the same time as the paddy bag 17 is removed from the machine, the next paddy bag 17 is opened and placed under the branch tube, the mouth of the removed paddy bag 17 is closed, and the paddy bag 17 is appropriately lowered out of the machine.

When the worker finishes replacing the paddy bag 17 and waits for other paddy bags 17 to be filled with paddy in this way, the worker sits on the butt support tool 10, leans back with the back support 9vc, and waits. The abutment 9 and the butt abutment tool 10 are then moved to a position facing the paddy bag 17 that is to be used.

Furthermore, when the paddy bag 17 that has been filled with paddy is lowered, or when all the paddy bags 17, 17... are first suspended from the ripping levers 7, 7... As shown by the chain line in Fig. 1, it is rotated toward the side of the grain lifting machine 4 and kept in an unused state. 13 and/or pins 15 are inserted into the upper and lower small holes 14, 14, 16, 16, etc. as appropriate.

As mentioned above, the present invention provides a tearing device for storing threshed grain behind the seat on the front side of the fuselage, and a pair of substantially horizontal upper and lower support frames 8a facing the tearing device from the outside. ,8b
is attached to the tip of the arm rod 12, and the upper support frame gai
y has a back support 9 attached, and a buttocks support 10 is attached to the lower support frame 8b.
, and the base of the arm rod 12 is rotatably attached to the machine frame on the back of the seat so that the backrest and buttrest can be switched between a used state and a non-used state. During standby, the auxiliary worker can place his/her weight on the back support 9 and the butt support 10 in an extremely stable state, and can safely board the aircraft even if the road surface or field is extremely uneven, and the machine vibrates or tilts. can do.

17.1 paddy bag left? . . . when hanging it on a tearing device or lowering a paddy bag filled with paddy outside the machine, if it becomes an obstacle depending on the direction in which it is lowered, the back support 9 and butt support tool 10 together with the frame 4 may The above-mentioned operations can be performed extremely easily and quickly by simply rotating the device to a position where it should not be.

Moreover, since the base of the arm rod 12 is rotatably attached to the machine frame on the back of the seat, when the arm rod is rotated toward the threshing device while driving on the road, the back and butt supports can be placed in a lower position. It can be stored and does not interfere with driving.

Furthermore, even if the worker moves on the deck 1\he is standing on during bagging work, the pair of upper and lower support frames 8a and 8b work together to protect the worker in two places, making the bag extremely safe. Can perform packing work.
