DE1110461B - Device for adjusting the discharge chute and the discharge flap of the conveyor channel of agricultural harvesting machines, in particular forage harvesters - Google Patents

Description

The invention according to patent 1076 429 relates to a device for adjusting the ejection sheet and the pivotable discharge flap of the agricultural conveyor channel provided on this Harvesting equipment, in particular forage harvesters, consisting of one from the driver's seat Towing vehicle to be actuated, with the ejector bow connected adjusting lever and a chain or cable pull or linkage engaging the ejection flap. The main patent sees Among other things, a two-armed device that can be swiveled and locked in a horizontal plane on the device Adjusting lever in front of which one arm is operated by means of an intermediate link, e.g. a rod, a rope or The chain hoist is articulated to the ejection arch and its other arm is directly or indirectly connected is brought within reach of the driver of the towing vehicle. With the two-armed adjustment lever only swivel the ejector elbow, while to adjust the ejector flap the rope or chain hoist must be operated independently of the adjustment lever. To do this, the operator has to let go of the adjusting lever, or he has to do both Use your hands to operate the discharge chute and discharge flap. If the operation happens during when driving, the driver does not have both hands free.

The invention aims to develop the subject matter of the main patent and consists in essential in the fact that the arm of the two-armed adjusting lever facing the driver or directly connected to a control lever pivotable about a horizontal axis and lockable is that via at least one intermediate link, for example a cable or chain hoist, with the Ejection flap is articulated. In this way you can move the control lever Adjust both the discharge chute and the discharge flap of the conveyor channel, namely both movements can be carried out simultaneously or independently. That in turn has the advantage that the operator has to adjust the discharge chute and the discharge flap only one hand is required so that the adjustment can also be carried out while driving, without the driver being hindered from steering the vehicle.

According to a further proposal of the invention, the operating lever can be designed as an angle lever be, one lever arm for operating the device, the other lever arm for articulation of the adjustment cable or device connected to the discharge flap

the discharge chute and the discharge flap

of the agricultural conveying channel

has been named as the inventor

Chain hoist is used. This training is not only structurally simple, but also allows the cheapest Leverage ratios. For locking the operating lever on the two-armed adjustment lever the bearing pin of the operating lever according to the invention can have a threaded attachment with screwed on Have nut and a spring, for example a plate spring, receive the operating lever adjustably presses against the two-armed adjustment lever. The operating lever is useful can be folded back into a rest position.

According to a further proposal of the invention, the two-armed adjusting lever can have a locking pin have, which is guided in a longitudinal groove of the console carrying the two-armed lever and an adjustable spring, for example also a plate spring, which accommodates the adjusting lever pushes against the console.

Details of the invention can be seen from the following description and from the drawing, which illustrates an embodiment of the subject invention. It shows

In the drawing, as in the embodiment according to the main patent, 1 denotes the housing of a mower chopping loader in which a knife drum 5 provided with a saw blade 4 is rotatably mounted. The device is supported ^: 'on wheels 9 and 10 and can be coupled to the trailer rail 7 of an agricultural tractor by means of a drawbar 6.'Das'Gehiftise 1 is provided with a delivery nozzle 11, to which-see-an intermediate piece 14 connects. This has at its upper end a turntable 15 - which 'is connected to a further turntable 16 of an ejection chute 17. The discharge chute 17 has at its free end an discharge flap 19 which can be pivoted about joints 18 ′ and by means of which the discharge range can be regulated.

A two-armed adjusting lever 20, 21, the tubular one, is used for the axial pivoting of the ejection sheet 17 Has cross-section and through an extension lever 22 into the area of the driver's seat 23 the tractor 8 is extended. The elongation lever 22 is axially displaceable in the adjusting lever and in various positions by means of a locking pin 24- detectable. To connect the adjusting lever 20, 21 with the rotatable ejection elbow 17 is a Articulated rod 31 is provided, this engages with its bent ends on the one hand in hooking bores 32 of the slewing ring 16 and is on the other hand in the arm 21 of the adjusting lever 20, -21-hooked / The " Hooking bores 32 are arranged distributed over a certain area of the circumference of the slewing ring 16, so that when the device is used, the ejection sheet 17 is in a certain basic position the toggle rod 31 can be 'adjusted'.

In contrast to the main patent, the lever 20, 21 by means of a pin 78 supports only horizontally-pivotable on a console 79, di ^&: the conveyor channel ^ 1% 14, 17-angeordnef is on the intermediate piece fourteenth To lock the ejector mechanism ⁵ '11 in a' selected position, the lever 20, 21; As can be seen in particular "from FIG. 3; between the bearing pin 78 'and'de'r AnlefiKsteller 'of the articulated rod 31 a locking pin ^: 80';" which extends through a curved longitudinal groove 81 "of the console 79". At its free, herausragendenr from the Längshut'50 81 ■ 'end of the pin ^80: threaded, is aufgesehraubt onto which a nut 82nd Between this and the console 79, a spring, for example cup spring 83, is arranged on the pin 80, which presses the arm 21 He's adjusting lever 20, - 21 against the console 79 via hardened steel disks 84 and 85 '. The compressive force of the plate spring 83 can be adjusted by means of the nut 82 and is otherwise selected in this way; that the adjustment leverzO; 21 "- on the one hand can be actuated relatively easily," on the other hand, automatic adjustment of the same is prevented. "

For Betätigen- of the adjustment lever "20 ^- 21 UNAE simultaneously for pivoting the ejector flap 19, an 'operating lever 86. This superposed' serves the driver's seat ■ the tractor vertically · comparable · pivotable on a horizontal bearing pin 87, of the free end Extension lever 22 is "ordered" / As FIG. 4 shows in particular, the bearing pin 87 is provided at its end protruding from the bore of the operating lever 86 with a thread onto which a nut 88 is screwed. A plate spring 89 is arranged on the bearing pin 87 between the 'nut 88' and the operating lever 86. This is supported by means of a hardened steel washer 90 against the nut 88 and presses the free end of the operating lever 86 against that of the extension lever 22. The nut 88 is also used to adjust the pressure force, the size of which is chosen so that the friction between the Extension lever 22 Tind prevents the operating lever 86 from an automatic "vertical" movement of the latter.
