Abstract

(57) [Summary] [Purpose] The purpose is to obtain a discharge auger device for combine harvesters with good workability. [Structure] The movable discharge auger is configured to be expandable and contractable with respect to the fixed discharge auger, and the auger is extended only when necessary during paddy discharge.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a discharge auger device in a combine harvester.

[0002]

[Prior art]

 The conventional discharge auger device for combine harvesters consists of a vertical discharge auger connected to the paddy tank and a horizontal discharge auger connected to this vertical discharge auger.

[0003]

[Problems to be solved by the device]

 The horizontal discharge auger as described above has a constant length, but the longer the horizontal discharge auger, the better the workability of discharge. However, considering the total length, width, strength, and workability of cutting, it is not possible to set a length that is too long. Therefore, the purpose of this plan is to obtain a discharge auger device for combine harvesters with good workability.

[0004]

[Means for Solving the Problems]

 In order to achieve the above objectives, the present plan provides the following discharge auger device for combine harvesters. That is, the horizontal discharge auger in the combine is composed of a fixed discharge auger and a movable discharge auger, and the movable discharge auger is configured to extend and contract with respect to the fixed discharge auger, and the spiral of the movable discharge auger is connected to the tip of the movable discharge auger. A fixed discharge auger is a discharge auger device in a combiner composed of a spring spiral fixed to the tip of the shaft.

[0005]

[Action]

 The movable discharge auger is configured to be expandable and contractible with respect to the fixed discharge auger, and the auger is extended only when necessary when discharging paddy.

[0006]

【Example】

 Embodiments shown in the drawings will be described below. The discharge auger in the combine has a vertical discharge auger 2 connected to the paddy tank 1 and a horizontal discharge auger 3 connected to the vertical discharge auger 2 as shown in FIG. This plan is configured to extend the lateral discharge auger in the combine as described above so that the auger can be extended only when necessary when discharging paddy. In FIGS. 1 and 2, 4 is a fixed discharge auger of the horizontal discharge auger 2, 5 is a movable discharge auger configured to be expandable and contractible, and the fixed discharge auger 4 and the movable discharge auger 5 are horizontal discharge augers. Make up 2. Specifically, the spiral shaft 7 of the movable discharge auger 5 is spline-fitted to the spoiler shaft 6 of the fixed discharge auger 4, and the outer cylinder 8 of the movable discharge auger 5 is externally fitted to the outer cylinder 9 of the fixed discharge auger 4. It is free to slide. The spiral of the movable discharge auger 5 is composed of a spring spiral 10, which is fixed to the tip of the shaft 7 and the tip of the shaft 6 and is expandable and contractible. A slide screw 12 driven by a motor 11 fixed to the outer cylinder 9 of the fixed discharge auger 4 is screwed to a slide fitting 13 protruding from the base of the outer cylinder 8 of the movable discharge auger 5.

In the lateral discharge auger 2 configured as described above, the slide metal fitting 13 is moved forward and backward by the slide screw 12 by driving the motor 11, whereby the outer cylinder 8 of the movable discharge auger 5 is also moved forward and backward. . As a result, the shaft 7 of the movable discharge auger 5 also slides back and forth in the shaft 6. Since the spring spiral 10 is fixed to the tip of the shaft 7 and the tip of the shaft 6, it expands and contracts as the shaft 7 expands and contracts. Therefore, during normal work, the movable discharge auger 5 is stored in the fixed discharge auger 4 as shown in FIG. In this way, the overall length and width during work will be shortened and workability will be improved. When it is necessary to discharge the paddy, the movable discharge auger 5 is extended from the fixed discharge auger 4 and used as shown in FIG. Further, the alignment of the discharge port during paddy discharge can be finely adjusted in the front-rear direction with a stepping motor or the like.

In general, while the paddy is being discharged by the discharge auger, the tip position of the auger may deviate from the turning angle set by the driver due to the reaction force of the paddy discharge. To solve this, the following control mechanism is incorporated. (1) Sensor for detecting ON / OFF of auger clutch lever (2) Potentiometer for detecting rotation angle of auger (3) Rotation actuator for motor, cylinder, etc. for controlling rotation angle of auger Control mechanism as above The position of the tip of the discharge auger is controlled by this, and if the tip of the discharge auger is misaligned due to the weight of the auger or the hull reaction force, feedback control is performed to return to the point O set by the driver. This O-point return control of the discharge auger is necessary only during paddy discharge, so a switch 15 that operates when the discharge auger clutch lever 14 is turned on is provided as shown in FIG. 3, and this ON signal is input to the controller 16. The O point can be returned to the whole range of the discharge auger's movable range when the paddy is discharged, and the controller program is simplified and reliability is improved. . In any case, the present invention is characterized in that the lateral discharge auger is composed of a fixed discharge auger and a movable discharge auger, and the movable discharge auger is configured to be expandable and contractable with respect to the fixed discharge auger.

[0009]

[Effect of device]

 According to the plan, it is sufficient to extend the auger only when needed when discharging paddy, and normally if the movable discharge auger is stored in the fixed discharge auger, the overall length and width during work will be shortened and workability will be reduced. Is improved. It also has the feature that it can be aligned during paddy discharge without moving the machine.
