[Work]

 The hopper 6 in which the grains are stored is supported by the vertical axis 7, and the discharge port 13b of the fried cylinder 13 and the inlet 6d part of the hopper 6 are joined together, so that it can withstand the grain weight and vibration of the machine body. It is firmly and stably supported so that it can. When the joint between the hopper 6 and the frying cylinder 13 is released and the hopper 6 is opened laterally outward about the vertical axis 7, the cover body 16 for covering the transmission mechanism 4a of the threshing machine 4 and the like together with the hopper 6. Since the swivel movement can be integrally performed, this portion can be widely opened, and maintenance work and the like can be appropriately and promptly performed without being hindered by the hopper 6 and the cover body 16.

【Example】

 The configuration of the present invention will be described with reference to the drawings. A is a combine shown as an implementation of a mobile thresher, and is equipped with a thresher 4 equipped with a straw cutting device 3 at the rear of a machine base 2 having a crawler type traveling device 1, and a side of this thresher 4. A rear part of a hopper 6 having a bagging device 5 is provided so as to be pivotally movable laterally outward of the machine body with a vertical axis 7 as a fulcrum. Therefore, a driver's seat 9 is installed between the hopper 6 and the driver.

The hopper 6 is formed in a bifurcated shape with a funnel surface 6a and is provided with discharge tubes 6c and 6c having a shutter 6b, and is configured into a tank shape capable of storing several grains of grain. The shaft ring 10 formed at the tips of the upper support frame 10a and the lower support frame 10b fixed to the rear wall portion is rotatably fitted around the pipe-shaped vertical axis 7 standing on the rear part of the machine base 2. In addition to supporting it, a support shaft 11 with a roller 11a is fixed to the front wall portion of the hopper 6 and supported by a U-shaped guide rail 12 provided laterally on a standing frame 9a at the rear of the driver's seat 9 for grain recovery. It is configured to be in a state.

At this time, the grain inlet 6d of the hopper 6 is inserted with the discharge cylinder 13a of the fried grain cylinder 13 which is firmly erected from the threshing machine 4, and the discharge cylinder 13a is provided on the inner wall above the inlet 6d. The fixed mounting piece 14 is mounted, and the inlet 6d and the discharge port 13b are closely joined to each other via the sheet member 14a. Therefore, the hopper 6 supports the weight of the hopper in which several bags of grain are stored in the state where the shutter 6b is closed, the vertical axis 7 and the guide rail 12 support the front and rear direction of the hopper 6, and the intermediate portion is lifted. Since it is mounted on the cylinder 13, it can be firmly and stably supported so as to sufficiently withstand the weight of the grain and the vibration of the machine body.

Numeral 15 is a predetermined number of bag hooks having a bag filling space on the machine base 2 for suspending the grain bags K, and the base thereof is fixed to the lower support frame 10b. Reference numeral 16 denotes a cover body attached to the rear surface of the lower support frame 10b, and a belt and a pulley provided on the machine wall of the threshing machine 4 between the hopper 6 and the threshing machine 4 at the inner part of the bagging space. The transmission mechanism 4a and the like are covered, and the support of the hopper 6 is reinforced. Reference numeral 4b is a lid side plate that can open and close the side wall of the plate chamber 4c.

Further, a plastic film 17 is attached to the inside of the funnel surface 6a of the hopper 6, or a smoothing surface is formed by coating, so that the funnel surface 6e has a smaller angle of repose than the conventional untreated hopper. The funnel surface 6a having an angle of repose greatly increases the capacity of the hopper 6. Further, as shown in FIG. 4, the joint portion between the hopper 6 and the fried grain cylinder 13 has a placing portion 14 projecting outward from the hopper 6 and placed on the discharge cylinder 13a. You may make it fasten and fix with the hook 18.

When harvesting and threshing of the napped culms is performed by the combine equipped with the grain collecting device of the present invention having the above-mentioned configuration, the grains are fried in the fried cylinder 13 and passed through the discharge port 13b and the inlet 6d. It is stored in the hopper 6 and is packed in the grain bag K by opening the shutter 6b. When maintenance or repair cleaning of the power transmission mechanism 4a or the handling chamber 4c is required during the combine operation or at regular inspections, the hopper 6 and the fried food barrel 13 are joined by fixing the hook 18 or the like. With the tool released and separated, pull the front part of the hopper 6 laterally outward, while the front part of the hopper 6 is guided by the guide rails 12 and swivels open smoothly laterally outward using the vertical axis 7 as a fulcrum. Then, the state shown by the dotted line in FIG. 3 is reached, and the hopper 6 and the cover body 16 can widely open and expose the transmission mechanism 4a portion and the side plate 4b portion of the threshing machine 4.

Therefore, it is possible to accurately and easily carry out the above-mentioned maintenance work in the inner part of the bagging device 5 accurately and easily without being hindered by the hopper 6 and the cover body 16 and efficiently. Further, in the above-mentioned embodiment, the hopper 6 is firmly joined and held on the grain inlet 6d portion and the threshing machine 4 side while being mounted on the discharge port 13d portion of the existing fried cylinder 13. Therefore, it is possible to provide a grain recovery device for a high-performance mobile thresher that can make the vertical axis 7 partial support structure simple and lightweight without vibration or grain leakage at the joint. You can
