Abstract

(57) [Summary] [Purpose] In the case of bag removal from a discharge auger, the purpose is to obtain a discharge auger discharge port in a combine that is not offset-filled. [Structure] Below the tip of the auger discharge port, the grain projection surface is retracted in the projection direction with respect to the pivot point, and a reflector having a curved surface with a forward downward slope is suspended and swingably suspended.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This plan concerns the outlet of the discharge auger in the combine harvester.

[0002]

[Prior art]

 The rod from the threshing machine is carried into the grain tank via the lifting cylinder, and the carried grain is discharged from the discharge port to the outside of the machine by the spoiler of the discharge auger. .

[0003]

[Problems to be solved by the device]

 With the combine auger's discharge auger, when the grain is pouched against the bag mounted on the cargo bed outside the machine, when the angle of the discharge auger may be horizontal depending on the height of the field, the cargo bed, and the road, it may be inclined at 45 °. The way of handling differs from the case of discharging. In either case, when fully discharged, the grain flow falls in a parabola at the discharge port, does not fall in the middle of the bag, and is filled in one direction, so it is difficult to fill in a full state. In addition, the number of bags to be loaded on the cargo bed is limited due to the one-sided filling, and the imbalance of the cargo bed due to the one-sided filling occurs. Therefore, the purpose of this plan is to improve this to obtain a discharge auger discharge port in a combine that does not cause uneven filling in the case of bag removal from a discharge auger.

[0004]

[Means for Solving the Problems]

 In order to achieve the above objectives, the present plan provides the following discharge ports for discharge augers in combine harvesters. That is, in a combine machine in which the grain projection surface is retracted in the projection direction with respect to the pivot point below the tip of the auger discharge port, and a reflector having a curved surface with a front downward slope is swingably suspended. This is the discharge port for the discharge auger.

[0005]

[Action]

 In the case of bag removal, the grain discharged from the discharge port of the discharge auger hits the reflector suspended below the tip of the auger discharge port and scatters, so it falls directly under the bag, and the grain remains unbalanced. Is packed in a bag.

[0006]

【Example】

 Embodiments shown in the drawings will be described below. First, referring to the combine, in FIG. 14, (1) is a track frame on which traveling rollers are installed, (3) is a machine frame installed on the track frame (1), and (4) is a feed chain (5) on the left side. Threshing section that is stretched and has a built-in handling cylinder, (6) is a mowing section equipped with a cutting blade (7) and a grain rod transport mechanism (8), and (9) is mowing through a mowing frame (10). A hydraulic cylinder for raising and lowering the section (6), (11) a driving section, and (12) a driver's seat. The combine harvester as described above has a grain tank that carries the grain from the threshing section (4) through a lifting cylinder, and has a discharge auger (13) that discharges the grain of this grain tank out of the machine.

When collecting bags with this discharge auger (13), the angle of the discharge auger (13) may be horizontal discharge as shown in FIG. 7 or as shown in FIG. 6 depending on the height of the field, loading platform, and road. There are variations such as a 45 ° inclination. When discharged at full opening, the grain flow falls in a parabola, so that the grain does not fall in the center of the bag (C), and is packed as shown in FIG. 6 and FIG. . This plan improves this.

According to the present invention, a grain projection surface is retracted below the tip of the discharge auger (13) with respect to a pivot point in the projection direction, and a reflector having a curved front downward slanted end is swingably suspended. It is hung. That is, in FIG. 1 and FIG. 2, (14) is a reflector, which is suspended so as to be swingable back and forth around a pivot point (15) at the lower end of the outlet, and its shape is the grain projection surface ( 16) is at a position retracted with respect to the pivot point (15) as shown in (a), and a lower end forms a curved surface (17) with a forward downward slope inclining (b). A balance wit (18) is provided on the back surface of the reflector (14). The balance wit may be integrally formed with the reflector or may be attached separately. The one shown in FIG. 3 shows that the reflector (14) has a concave shape.

The above-mentioned reflector (14) takes the position shown in FIG. 4 when the auger is horizontally discharged, and takes the position shown in FIG. 5 when the auger is tilted at 45 °. The grain discharged from (13a) hits the projection surface (16) of the reflector (14), falls directly below the curved surface (17), and is filled in the center of the bag. Therefore, the filling is not biased. Since the grain projection surface of the reflector (14) is eccentric from the so-called fulcrum (15), with respect to the fulcrum (15), the grain projection surface is retracted in the projection direction. When the reflector (14) alone loses the discharge pressure of the grain, the balance wit (18) is provided on the rear surface of the reflector (14) to adjust the discharge angle of the auger. Regardless, the reflector (14) can be held at a proper position and the discharged grains can be averaged and scattered. As shown in FIGS. 12 and 13, since the work is carried out at night, the guide rod (19) and the light (20) are attached to the tip of the discharge auger (13), the total length is long, and the paddy bag is augered. When you want to cover and discharge, it is difficult to put the bag in and it takes time to cover it. Therefore, as shown in FIGS. 8 and 9, a hole (21) for entering the light (20) is formed in the upper part of the auger tip, the light (20) is inserted into the hole (21) from above, and the auger nut (22) is used. Welding is supported first. The light (20) is provided with a reflecting plate (23) as shown in FIG. 11 to adopt a shape that diffuses the light from the light source (24). In addition, (25) is a glass plate. Further, (26) is a rubber boot of the discharge port.

According to the above, since the light (20) is built in the discharge auger (13), the whole length is short and the paddy bag can be easily attached. Moreover, as shown in FIG. The spiral (13b) discharges the grains toward S in the direction (d), and the grains are discharged toward the direction (d) with respect to the length L of the discharge port of the discharge auger as shown in FIG. Since it is emitted, the light of the light is projected downward without being obstructed by the grain, and night work is not hindered. In any of the above cases, the proposal is that the grain projection surface is retracted in the projection direction with respect to the pivot point below the tip of the auger discharge port, and the reflector having the curved front downward slanted end is swingably suspended. It is characterized by.

[0011]

[Effect of device]

 According to this plan, since the reflecting plate was provided below the tip of the auger discharge port, the discharged grain hits the grain projection surface and falls along the curved surface at the lower end, so the grain falls in the middle of the bag. Moreover, since the grain projection surface of the reflector plate is retracted in the projection direction with respect to the pivot, that is, at a position eccentric from the pivot, it will face the projection direction of the grain regardless of the discharge angle of the auger. Therefore, it is possible to keep the proper position and well disperse the discharged grains on average. Therefore, in the case of bag removal, it is possible to prevent the incomplete filling due to the one-sided filling, and prevent the imbalance in the loading platform due to the one-sided filling.
