[0003]

[Problems to be solved by the device]

 However, according to the above-described conventional configuration, the reducing cylinder has an unstable tilted posture, and a heavy lifting helix shaft is rotatably installed inside the reducing cylinder, which easily shakes due to the vibration of the airframe. There is a problem that the machine wall part of the mounting part is damaged by vibration. In addition, the transmission case, which is cantilevered on the wall of the processing chamber that is bulged on one side of the threshing machine wall, causes distortion and vibration due to the twisting force due to the rotating action of the processing cylinder when a high load occurs on the processing cylinder. There is a problem that causes it. Therefore, the present invention is intended to solve the above-mentioned conventional problems and to provide a reducing cylinder support device for a thresher capable of firmly mounting and supporting the reducing cylinder and the processing cylinder transmission case with a simple structure. .

[0004]

Means for Solving the Problems In order to achieve the above object, a reducing cylinder support device in a threshing machine according to the present invention comprises a swing sorting body 8 installed along a drafting chamber 6 and a processing chamber 7 connected to a rear portion thereof. No. 1 port 11 and No. 2 port 9 are installed at the front and rear positions below the machine, and the grain is discharged from the No. 1 port 11 through the fried cylinder 12 to the outside of the machine and the reduced grain is also delivered to the No. 2 port 9. In the threshing machine 1 which carries out reduction pumping toward the front side of the rocking sorting body 8 via the reducing cylinder 10, the reducing cylinder 10 is arranged along the threshing machine wall 1a, and its base and discharge port 10b are arranged. A transmission case 15 which is fixed to the machine wall 1a and obliquely installed in a forwardly inclined shape and which rotationally drives the processing cylinder 7a supported in the processing chamber 7 is arranged above the reduction cylinder 10 and the transmission case 15 is provided. 10 and the intermediate portion of the reducing cylinder 10 are connected by a connecting member.

[0005]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A threshing machine 1 equipped with the device of the present invention is mounted on a machine stand 4 which is provided with a mowing section (not shown) and a driver's seat 2 and is moved by a crawler traveling device 3, and a grain tank is provided on the side of the threshing machine 1. Alternatively, a grain tank 5 such as a hopper tank is installed in parallel to form a combine for performing the cutting and threshing work. This threshing machine 1 threshes the grain culms cut and conveyed from the reaping section by the handling cylinder 6a in the handling room 6 and the processing barrel 7a in the processing chamber 7 connected to the rear side of the handling room 6, and The threshing products are received by the swing sorting body 8 arranged below them to perform swing sorting.

The No. 2 product in which straw debris and the like are mixed in the grain by the above-described rocking selection action is transferred from the screw shaft 9a in the No. 2 port 9 to the reducing cylinder 10 and is transferred to the rocking selection unit 8. In addition to carrying out reduction-lifting and re-sorting, the No. 1 product free from the inclusion of straw waste etc. is a fried food that rotatably houses a fried helix 12a connected to the end of the spiral shaft 11a in the No. 1 mouth 11. The grain is fried in the cylinder 12, and discharged and stored in the grain tank 5 through the discharge port 12b formed at the upper end. In addition, cut straws, scraps and the like are discharged from a dust outlet opened at the rear of the thresher 1. The grains stored in the grain tank 5 can be discharged to appropriate places outside the machine by operating a series of grain discharge mechanisms (discharge spirals) 13 when they are full.

The mounting configuration of the reducing cylinder 10 and the fried grain cylinder 12 and the positional relationship between the two are configured as shown in FIGS. 3 and 4. That is, the reducing cylinder 10 is attached to the No. 1 mouth 9 so that the base of the spiral shaft 10a rotatably supported inside thereof is located below the No. 1 spiral shaft 9a, and the base of the frying cylinder 12 is Along the threshing machine wall 1a so as to have a front inclination shape that intersects with the fried cylinder 12 in a side view, and passes through the inside, and a reducing port (discharging port) 10b formed at the upper end thereof is formed. It is fastened and fixed to the threshing machine wall 1a with a mounting screw 14. Further, in the embodiment, the reducing cylinder 10 is obliquely installed forward in a slanting shape, and the second product can be accurately reduced and thrown from the discharge port 10b to the front side of the start end of the swing selecting body 8. This is possible, and sufficient swing re-sorting is provided, so that the sorting is performed well.

In addition, when viewed from the front, the fried grain barrel 12 has a base that is sufficient for passing the reducing barrel 10 between the threshing machine wall 1a and the threshing machine wall 1a via the transfer barrel 12c between the base and the opening 11. While securing the space, the upper side thereof is erected inwardly inclined toward the threshing machine 1 side so that the inner side surface 12d of the fried grain tube 12 intersects the extension line 10c outside the reduction tube 10 inside. I have to. The fried food cylinder 12 in the embodiment is brought as close as possible to the machine wall 1b of the processing chamber 7 formed by bulging from the machine wall 1a of the threshing machine 1 toward the grain tank 5 side, and the fried food cylinder 12 The upper part of the above is moved closer to the threshing machine 1 side so that each mechanism is effectively installed while narrowing the space formed between the grain tank 5 and the threshing machine 1. In the thresher that does not project the processing chamber 7 toward the grain tank 5 side, the fried grain cylinder 12 may be placed directly close to the reducing cylinder 10.

With the above configuration, since the grain tank 5 is installed close to the thresher 1, the grain size can be reduced without increasing the width of the body, and a cheap combine combine with good workability can be manufactured. There is. Further, the transmission case 15 for rotationally driving the processing cylinder 7a supported in the processing chamber 7 is rotationally transmitted by tensioning the belt 17 from the pulley 16a provided on the blower fan rotation shaft 16 with the pulley 15a. The transmission case 15 is projectingly fixed to the processing body wall 1b in a state of approaching the upper side of the reducing cylinder 10, and the outer side portion separated from the threshing machine wall 1a to the grain tank 5 side and the upper middle of the reducing cylinder 10. The parts are vertically connected by a connecting rod (connecting member) 18.

As a result, the reduction cylinder 10 in the forwardly inclined posture is fixed along the machine wall 1a on both sides of the base portion and the discharge port 10b, and the middle portion of the reduction cylinder 10 is further connected to the transmission case 15. Therefore, the reduction cylinder 10 tilted forward has high rigidity and is strongly supported against the rotation by the spiral shaft 10a and the vibration of the machine body. In addition to preventing vibration damage, it also prevents contact with the fried food barrel 12 that is installed in close proximity. In particular, integrally connecting the transmission case 15 and the reduction cylinder 10 also reinforces and supports the transmission case 15 by the reduction cylinder 10, so that the transmission that tends to fluctuate when the processing cylinder 7a is under high load. The case 15 can be fixed stably.

[0012] The above-described support structure connects the reducing cylinder 10 and the transmission case 15 in the vertical direction by the connecting member 18 at a position separated laterally from the thresher wall 1a, so that the rigidity is improved. Highly rigid support can be provided at a low cost with a simple structure. Further, the reducing cylinder 10 can be effectively used as a mounting frame for a member constituting a nearby transmission mechanism such as a processing cylinder transmission mechanism described below. That is, a support arm 19b for supporting the tension pulley 19 of the belt 17 is swingably pivoted below the middle portion of the firmly fixed reducing cylinder 10 and the reducing cylinder 10 is tensioned by a spring 19a. Due to the forward tilted posture, the proper position of the belt 17 can be pressed stably and accurately. Reference numeral 20 is a drive pulley of the handling cylinder 6a which is transmitted from the blower fan rotating shaft 16 via a belt 21.
