Description

[0001]
[Industrial applications]
The present invention relates to a combine dumping auger, which takes out and transports harvested grains stored in a Glen tank outside the machine.
[0002]
2. Description of the Related Art
There is a mode in which a part of the spiral is polymerized in order to expand and contract the combine auger auger (JP-A-63-279719, JP-A-1-121340, etc.). Since it is polymerized heavily, a special spiral configuration is required, and the driving resistance at the time of expansion and contraction is large, making it difficult for smooth expansion and contraction operations to be performed.
[0003]
[Means for Solving the Problems]
The present invention provides a mowing device 7 that cuts and transports grain culms on a chassis 6 having a crawler 5, a threshing device 8 that receives and transports grain hulls, and a grain that accommodates threshed grains. A tank 9, a vertical auger 11 for transferring grains discharged backward by a bottom auger 10 at the bottom of the Glen tank 9, and a dumping auger 12 connected to an upper end of the vertical auger 11 are provided. In the combine, the vertical auger 11 is configured to be pivotable and determine the horizontal position of the dumping auger 12, and the dumping auger 12 is configured to be able to change its angle in the vertical direction by a telescopic cylinder 14, The dumping auger 12 is composed of a base tube 15 connected to the vertical auger 11 and a zoom tube 16 which is fitted on the outer periphery on the distal end side and can be expanded and contracted. 17 The helical shaft 18 having the helical shaft 18 is mounted, and the helical shaft 4 composed of a square shaft is fitted in the helical shaft 18 in the zoom cylinder 16, and the helical shaft 4 is integrated with the zoom cylinder 16. When a plurality of spiral bosses 2 each having a fixed length and having a spiral 1 formed on a peripheral surface thereof are inserted along the spiral shaft 4, the spiral boss 2 is movable in the longitudinal direction of the spiral shaft 4 but is rotatable. The helical bosses 2 are configured to rotate integrally with each other, a spring 3 having a fixed length is interposed between the helical bosses 2, and a wire 27 is passed through a central hollow portion of the helical shaft 18. The base of the wire 27 is connected to the reel 28 of the motor M2, and the tip of the wire 27 is connected to the helical shaft 4. The drive of the motor M2 shortens the zoom barrel 16 against the spring 3. to be configured as the configuration of the combine HaiKoku auger characterized by such .
[0004]
[Action and effect of the invention]
When expanding and shrinking the auger 12 , the interval between the spiral bosses 2 of the helical shaft 4 is adjusted by moving the cylindrical body around which the helical boss 2 is mounted and the helical shaft 4 in the axial direction. The length can be adjusted or the storage length can be changed by expanding or contracting with or against the tension. Regardless of whether the interval between the spiral bosses 2 is increased or shortened, the grain transfer can be performed by rotating the spiral shaft 4.
When the motor M2 is driven, the zoom cylinder 16 is shortened via the wire 27 connected to the reel 28.
[0005]
In this way, the distance between the spiral bosses 2 is expanded and contracted by expanding and contracting the spiral bosses 2 mounted on the spiral shaft 4 against the springs 3, so that the spiral shafts 4 and the spiral bosses 2 expand and contract. Can be performed smoothly and quickly, the configuration can be simplified, and the configuration can be reduced in price.

【Example】
The combine is mounted on a chassis 6 having a crawler 5, on which a harvesting device 7 for harvesting and transporting the grain culm, a threshing device 8 for receiving and grain-threshing the transported grain culm, a Glen tank 9 for accommodating threshed kernels, There are provided a vertical auger 11 for transporting grains discharged backward by a bottom auger 10 at the bottom of the Glen tank 9 and a waste auger 12 connected to the upper end and capable of being transported horizontally. 13 is a cockpit.
[0007]
The vertical auger 11 is pivotable to determine the horizontal position of the dumping auger 12, and the dumping auger 12 can be vertically angled at its upper end by a telescopic cylinder 14. It has a vertical auger 11 and a bottom auger spiral.
The dumping auger 12 has a base tube 15 connected to the vertical auger 11 and a zoom tube 16 that can be fitted and contracted to the outer periphery of the distal end side. and JikuSo the helical shaft 18 having a 17, in the zoom barrel 16, the spiral shaft 4 made of telescopic square shaft to the spline shaft fitted to the helical axis 18 and JikuSo, the zoom barrel 16 It can be expanded and contracted integrally.
[0008]
Along the helical axis 4 and fitted helical boss 2 of predetermined length, although the direction of the spiral shaft 4 is movable in the rotating direction is configured to rotate integrally. Further, a spring 3 having a fixed length is interposed between the spiral bosses 2. A spiral 1 is formed on the outer periphery of each spiral boss 2.
Reference numeral 19 denotes a discharge port at the tip of the zoom cylinder 16, reference numeral 20 denotes a screw rod which expands and contracts the zoom cylinder 16 with respect to the base cylinder 15, rotatably supports the bracket 22 of the base cylinder 15, and is driven by forward and reverse rotation of the motor M1. The distal end is screwed into the bracket 21 on the zoom cylinder 16 side. Reference numeral 23 denotes a bearing metal, which is provided in the distal end of the base cylinder 5 and bears the distal end of the spiral shaft 18.
[0009]
4 is different from the above example in that slide cylinders 24 and 25 having slightly larger diameters are provided at two positions before and after the distal end of the base cylinder 5, and the zoom cylinder 16 is mounted on the outer periphery of these slide cylinders 24 and 25. It is inserted and inserted to extend and contract smoothly. The bearing metal 23 is attached to the inner periphery of the slide cylinder 25 on the distal end side.
In FIG. 5, a different point from the above example is that, instead of the slide cylinders 24 and 25, a guide rod 26 of an appropriate length is fixed to the outer peripheral portion of the tip of the base cylinder 5 at least in a triangular arrangement. The zoom barrel 16 is inserted into the outer periphery of the guide 26 to guide the zoom barrel 16, thereby reducing the zoom resistance.
[0010]
In FIG. 6, the difference from the above example is that the zoom cylinder 16 and the screw shaft 20 that expands and contracts the helical shaft 4 are connected by a wire 27 that is wound by a motor M2. The wire 27 passes through the central hollow portion of the helical shaft 18 on the base side, connects the base to the reel 28 of the motor M2, connects the tip to the helical shaft 4, and resists the spring 3 by forward and reverse driving of the motor M2. It is shortened and extended by the tension of the spring 3.
