NL1034713C2 - Accessory for cutter device used in agriculture for e.g. cutting grass, comprises hydraulically extendible blowpipe for directing cut material into trailer behind tractor - Google Patents

Abstract

The device comprises a hydraulically extendible blowpipe mounted directly on a tractor which follows behind the cutter. The cut material is sucked into the pipe and then blown into a trailer being towed behind. The blowpipe comprises a second pipe which can move via rollers and guides over a first pipe, and a hydraulic drive unit for moving the second pipe.

Dear reader, 5

Hereby we send you the technical description concerning the hydraulically extendable blowpipe on forage harvesters, which are used in agriculture such as for chopping corn, grass, pre-dried grass etc.

This hydraulically extendable blowpipe has been specially developed to directly drive a chopper with a silage wagon connected to the chopper during chopping 10, which means that little product is spilled and the tractor remains clean.

As you can see on Appendix 1, on which the different types are drawn, you can clearly see the difference in how far the product is led, so that less is lost.

Technical description: Annex 2

The hydraulically extendable blowpipe consists of the following parts: A) First blowpipe (similar to traditional blowpipe, however, the same cross-section everywhere) B) Second blowpipe (it slides through rollers and guides over the first blowpipe) C) Hydraulic drive unit (this drives the drum) on which the steel wire is wound, this steel wire is simultaneously wound on and unwound so that there is no difference in length). This can also be performed with a hydraulic or pneumatic cylinder, drive unit.

D) The steel wire attached to the second blow pipe and a bypass wheel at the end of the first blow pipe has displaced the second blow pipe, and can be put in any position.

30 E) Electrically operated valve (transferred from existing installation).

The hydraulically extendable blow pipe is height-adjusted and horizontally rotated by existing drives.

Method:

Cutting pattern with conventional (fixed) blower pipe. Appendix 3 T.b.v. for mowing parcels: 5 1. Disconnect the silage wagon behind the tractor and couple behind the forage harvester incl.

hydraulic hoses, lighting and the like

2. If the car is full halfway through the plot, it becomes even more time consuming.

You then have to stop, drive backwards with a forage harvester and then put a silage wagon in and shred a piece and stop.

10 3. Drive backwards with the forage harvester with silage wagon and disconnect with all hoses, etc.

4. Drive the tractor with the empty silage wagon next to it, disconnect the wagon, change the wagon, connect the hoses.

5. You can now continue shredding with the forage harvester with attached 15 silage wagon.

Cutting pattern with the new hydraulically extendable blow pipe. Appendix 4 T.b.v. the mowing of parcels: 1. the hydraulically extendable blower pipe can be driven directly behind the shredder with the tractor with 20 attached silage wagon.

2. If the car is full halfway through the plot, you must stop, reverse with the tractor and silage wagon and the forage harvester.

3. Then plug in and chop a piece to be able to park the tractor with a full wagon. 25 4. The chopper goes back to the old track, the tractor with an empty silage truck drives behind it and we can chop on.

Claims (5)

1. Saving time by no longer connecting and disconnecting the silage wagons between the tractor and forage harvester. 2. No more mess with support leg, hydraulic hoses, lighting cables and the like. 3. No leakage of hydraulic oil when connecting and disconnecting the hydraulic hoses from the silage trucks. 4. The tractor stays clean because the chopped product is guided much further. 5. The alignment of the product beam can be much more accurate so that less is spilled. 1 034 713 -4- Appendices: Appendix 1. Situation sketch of forage harvester, tractor and silage wagon. Appendix 2.
