Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine grain tank mounting structure capable of storing threshed grains in a grain tank and effectively discharging the grains from the grain tank by a spiral conveyor tube.

[0002]

[Prior art]

 Conventionally, in a combine harvester in which the threshing section behind the mowing section and the Glen tank behind the driver's seat are arranged side by side in the horizontal direction, the grain is thrown from the threshing section into the Glen tank by the lifting cylinder and stored. The structure is such that the grains are discharged from the tank via the vertical conveyor cylinder and the discharge spiral conveyor cylinder.

[0003]

[Problems to be solved by the device]

 However, since the lifting cylinder and the vertical conveyor cylinder are equipped separately, the structure is large and complicated, and the weight is heavy.In a wetland, the aircraft easily sinks and the traveling performance is poor. There is a problem that it is impossible to equip a combine.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve such problems and to make it suitable for a compact combine with a compact structure. Therefore, the No. 1 helix conveyor at the lower part of the threshing section and the discharge helix conveyor at the lower part of the grain tank are designed. The horizontal horizontal axis is provided so that they can be conveyed in opposite directions, and both discharge ports that can be opened and closed by shutters are provided on the upper part of the fried helix conveyor cylinder that is erected upright so as to communicate between the ends of both helix conveyors. One discharge port is connected to the upper part of the Glen tank, and the other discharge port is connected to the base of a discharge spiral conveyor tube that can swivel horizontally.

[0005]

[Action]

 Therefore, when storing grains in the grain tank, close the discharge port on the side of the discharge spiral conveyor and open the discharge port on the side of the grain tank to lift the grains to be conveyed by the first spiral conveyor. It will be possible to lift the grain by the grain spiral conveyor tube and put it into the Glen tank from the discharge port.When discharging grains in the Glen tank, close the discharge port on the Glen tank side and discharge it. If the discharge port on the side of the spiral conveyor is open, the grains conveyed from within the grain tank by the discharge spiral conveyor are fried by the fried spiral conveyor cylinder and discharged from the discharge port to the spiral conveyor cylinder. It can be discharged by a spiral conveyor tube.

【Example】

 FIG. 2 is a perspective view schematically showing a small combine, in which a threshing section A and a grain tank B, which are arranged side by side, are mounted on a machine supported by both crawlers 9, and a cutting machine is provided in front of the threshing section A. The section C is provided, and the steering column 10 and the driver's seat 1 are provided in the front and rear in front of the Glen tank B on the right side of the cutting section C, which is configured in the same manner as the conventional structure. B is divided into a resin-made top sucker 11a installed above and a tank portion 11b that can be pulled out to the right side of the machine body below the top sucker 11a, and a discharge spiral conveyor below the tank portion 11b. 3 and the No. 1 spiral conveyor 2 at the lower part of the threshing section A have the same spiral direction and the same horizontal axis, and the forward / reverse rotation motor 12 allows forward / reverse rotation to be freely performed. while The fried helix conveyor tube 4 in which the helix conveyor 8 which is communicated and driven by the lower motor 13 is installed is erected so as to extend to the inside of the top sucker 11a, and the top of the fried helix conveyor tube 4 is placed above the top sacker 11a. The discharge port 5 is formed so as to be opened inward of the sucker 11a and to which the shutter 5a is openably and closably attached.

Further, above the upper end of the fried helix conveyor tube 4, a rotary tube section 4a equipped with a tooth section 16 meshing with a gear 15 for driving the forward / reverse rotation motor 14 is provided so as to be able to turn 180 degrees. A discharge opening 6 having a shutter 6a openably attached is formed on the outer peripheral surface of the rotary cylinder portion 4a, which is continuously provided and the upper end portion of the spiral conveyor 8 looks into, and the base portion communicates with the discharge opening 6. The discharge spiral conveyor cylinder 7 is fixed to the rotating cylinder portion 4a, and the discharge spiral conveyor cylinder 7 extending in the horizontal direction and having a downward discharge port 17 at the tip is rotationally driven by a motor 18 on the rear end side. Although the spring controller 19 is internally provided, the first spiral conveyor 2 and the discharge spiral conveyor 3 may be formed so that their spiral directions are opposite to each other.

Therefore, when the grain is stored in the Glen tank B, if the discharge port 6 on the discharge spiral conveyor cylinder 7 side is closed and the discharge port 5 on the Glen tank B side is opened as shown in FIG. , The grain conveyed by the first spiral conveyor 2 which is normally rotated by the forward / reverse rotation motor 12 can be fried by the fried helix conveyor tube 4 and fed into the Glen tank B from the discharge port 5, and When discharging grains stored in the Glen tank B, close the discharge port 5 on the Glen tank B side and open the discharge port 6 on the discharge spiral conveyor cylinder 7 side as shown in FIG. The grain in the grain tank B, which is conveyed by the discharge spiral conveyor 3 which is reversed by the forward / reverse rotation motor 12, is fried by the fried helix conveyor tube 4 and discharged from the discharge port 6. It can be discharged by the discharge spiral conveyor cylinder 7 while being sent to the spiral conveyor cylinder 7.

In that case, as shown in FIG. 9 and FIG. 10, when the rotary cylinder portion 4a is rotated in the arrow A direction or the arrow B direction, the discharge spiral conveyor cylinder 7 is moved from the state of being housed in the machine to the left and right directions. Since it can be turned about 180 degrees, it can be turned in a desired direction, and at the time of maintenance, as shown in FIG. Maintenance work can be done easily.

[0010]

[Effect of device]

 As described above, according to the present invention, the grain can be conveyed from the threshing section A to the grain tank B and from the grain tank B to the discharge helix conveyor tube 7 by the single lifted helix conveyor tube 4, respectively. As a result, it will be possible to make it lightweight and compact structure, and it will be possible to further improve drivability in wetlands by weight reduction, and it will be possible to equip a small combine with the Glen tank specification. It has a feature that can be suitably implemented.
