Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine dropper for a knotter.

[0002]

[Prior Art]

 There are two types of combine harvesters, one that releases straw after threshing, in the rear of the threshing part, in unbound or further cut, and one that binds it by a knotter and discharges it from the rear. Although the ones to be selected are popular, those to be released after bundling are sequentially released by the knotter dropper device depending on the natural dry condition of the grain and the use of straw, etc. There is a single-bundle drop type and a focused-fall type that stores a certain amount of straw with a dropper device and discharges it together. In the conventional dropper device, a fork-shaped drop guide is set at the lower end of the guide unit that guides the fall of the binding straw just after it is dropped from the rear end of the transporting device that conveys the binding straw. And then sequentially drop (single bundle drop) or set upward and elastically and when a certain amount of bundle is stored, the drop guides are elastically inclined downward in the downward direction by its own weight and discharged collectively. A selective structure of (focusing drop) was adopted.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional single bundle drop type drop guide set state, the lower end of the drop guide is fixedly projected by inclining further downward from the lower end of the dropper guide part, so that the lower end of the drop guide is excessive on the road surface. There was a problem that the fall guide contacted the road surface when the vehicle body tilted to the left or right or front and rear, and disturbed the straw that had already fallen on the ground. The present invention aims to solve these problems.

[0004]

[Means for Solving the Problems]

 The device of the present invention for solving the above problems is provided with a knotter B and a binding straw conveying device C behind the threshing part of the combine, and a dropper D for dropping the binding straw 12 at the end side of the binding straw conveying device C. In the above, a drop guide 23 for guiding or temporarily receiving the falling straw 12 is placed below the guide portion 19 of the dropper D 1 for guiding the falling of the straw 12. In the upright state, the falling guide 23 sequentially drops the bundling straws 12 with the back surface as a guide surface, and in the fallen state, stores the bundling straws 12 as a receiving surface and stores a certain amount of the bundling straws 12 to elastically support them. The feature is that the sloping straw 12 that is stored by descending and sloping when the bundling straw 12 exceeds a certain amount is dropped onto the ground.

[0005]

[Action]

 The drop guide 23 pivotally supported on the tip of the drop guide portion 19 of the bundling straw 12 of the dropper D is fixedly set in the standing state when a single bundle is dropped and used as a drop guide. Evenly align and drop onto the ground. At the time of focused fall, the fall guide 23 is elastically set in a laid state to store a certain amount of the fall bundling straw 12, and the fall guide 23 elastically descends and tilts due to its own weight to bring the bunch of bound straw 12 to the ground. Drop all at once. When the bundling straw 12 is dropped, the fall guide 23 elastically returns to the original set position, and the tip height is maintained at a high position.

【Example】

 The drawings show an embodiment of the present invention. At the rear of the combine fuselage on the left side in the direction of travel (on the uncut side), there is provided a straw conveying device A comprising a feed chain for carrying the straw 2 fed from the threshing section to the rear center. A knotter B that binds the fed straws 2 in order by a fixed amount is provided in the rear of the knotter B. Numeral 3.4 is a root pushing plate that pushes the straw 2 sent from the straw conveying device A to the side of the knotter B to align the roots 2 and a root aligning plate that further aligns the roots at the portion B of the knotter, both of which are shaken by the drive mechanism 6. While being moved, it is brought into contact with the base of the straw 2 to perform root alignment.

On the knotter frame 8 below the sweeper 7 of the knotter B, a carrier device C for binding straws 12 is horizontally rotatably attached via a feeder arm 9 and a feeder shaft 11. The carrier C has a feed chain 15b wound around a sprocket (not shown) at the front and rear ends of a horizontally supported chain case 15a, and the feed chain 15b and a pressing guide 15c arranged above the feed chain 15b. It is a mechanism that holds the united straw 12 between them and sends it out.

A bracket 14 having a longitudinal sleeve 13 is provided on the side of the tip of the carrying device C. A dropper shaft 16 is rotatably fitted to the sleeve 13 and 17 is a dropper shaft. A set bolt for setting 16. By rotationally adjusting the dropper shaft 16, the dropper D described below can be freely adjusted in its direction as shown in FIG.

A dropper D is attached to the lower end of the dropper shaft 16 via a dropper arm 18, and the dropper is attached to the tip of the dropper arm 18 and has a dogleg shape in a side view. A guide portion 19 formed of a plate also serving as a frame, a large number of brackets 21 projecting from the rear surface of the lower end of the guide portion 19, a guide shaft 22 rotatably supported by the bracket 21, and a base end portion. It is provided with four fork-shaped drop guides 23 that are fixed to the guide shaft 22 and that can be turned up and down integrally, and the drop guides 23 have an inverted "F" shape in a side view as shown in the drawing. I am doing it. The drop guide 23 does not necessarily have to be in the shape of a fork, and can be configured as a plate-shaped blade.

As shown in FIG. 2, the fall guide 23 stands upright and is set in a slightly forward leaning posture (a). The leading end is slightly upward and the proximal end is almost horizontal. ), And there are three postures, ie, a downward lying posture (c) in which the whole is almost downward. A notch 24 is formed at the tip of the guide portion 19 to allow each fall guide 23 to stand upright. One of the drop guides 23 is provided at its base end with a connecting lever 26 extending in a forward direction so as to rotate integrally with the guide shaft 22. A bracket 27 is provided on the bent portion of the back surface of the guide portion 19, and a restriction lever 29 is pivotally supported on the bracket 27 via a lever fulcrum 28.

A spring 31 is stretched between the front end of the regulation lever 29 and the back surface of the guide portion 19 so as to adjust the elasticity, and urges the regulation lever 29 to rotate clockwise. A stopper 32 protruding from the upper surface of the front end portion of the lever 29 comes into contact with the back surface of the guide portion 19 so that the rotation thereof is restricted. Further, a shaft hole which can be connected to the tip of the connecting lever 26 by the set shafts 30a and 30b is bored at the rear end of the regulating lever 29 and a position slightly forward thereof. The fall guide 23 is fixedly set in the posture (a) in FIG. 2, and when it is connected by the set shaft 30b, it is also set in the posture (b). At this time, the spring 31 and the stopper 32 are used to set the time. It is set so that it can be elastically rotated up to the posture (C) in the direction.

A sleeve 33 a is rotatably fitted to the dropper shaft 16 between the sleeve 13 and the dropper arm 18, and a sleeve 33 b fixed so as to intersect the sleeve 33 a in the horizontal direction includes: One end of the adjusting rod 34 is fitted and fixed. A sleeve unit 36, in which two sleeves 36a and 36b are vertically and horizontally crossed and fixed to each other, is provided on the right side of the frame of the main body 1 (on the side of the cut land). The other end of the adjusting rod 34 is inserted into one of the sleeves 36b so that the adjusting rod 34 can be set at an arbitrary slide position by the set bolt 38. ing.

With this mechanism, the transporting device C can be set by freely changing its direction, and, together with the above-described direction adjustment of the dropper D, the falling position of the bundling straw 12 with respect to the traveling path of the combine. You can adjust the direction. Further, these mechanisms allow the storage device C and the dropper D to be stored along the rear end of the machine body 1 as shown in FIG. 3 while minimizing the vehicle body length. When dropping a single bundle with the dropper D configured as described above, the drop guide 23 is set to the posture shown in FIG. 2A, and the tip of the connecting lever 26 is fixedly set by the set shaft 30a. In this state, when the binding straw 12 is discharged from the transporting device C, it is guided by the back surface of the fall guide 23 which is tilted upright and falls on the ground with the landing directions and intervals aligned without hitting an obstacle in the middle.

In the case of focusing and dropping, the tip of the connecting lever 26 is set on the set shaft 30b and the drop guide 23 is set at the position (b). In this case, the bundling straw 12 discharged from the transport device C drops onto the drop guide 23 while being guided by the rear surface of the guide portion 19, and when a certain amount of the bundling straw 12 is stored therein, it resists the spring 31. The fall guide 23 descends and inclines to the posture of (c) in FIG. 2, and the bundled straws 12 stored all fall into the ground with the bundled straws 12 gathered together. ) Return to the position and wait for the next drop. The tension of the spring 31 is adjusted depending on which engagement hole the upper end of the spring 31 is locked in, and the amount of the binding straw 12 stored on the drop guide 23 is adjusted.

[Effect of the device]

 Since the dropper device of the present invention is configured as described above, depending on the dry condition of the culms and the processing direction afterwards, single drop dropping by dropping one bundle or a certain number of bundles are collected and dropped. There is an advantage that either one of the focused focusing drops can be selected and carried out with a single device, and in the case of a single bundle drop, the bunch straw is guided to the back side of the drop guide and drops smoothly, so the position and posture of the drop is stable. . In addition, the tip of the drop guide when a single bundle is dropped is erected and its end point is higher than the conventional one, so the lower end of the drop guide mechanism abuts the stubble on the field or the bundle that has already dropped. Is also resolved.
