Zum Verändern der Höhe h der vom Förderband mitgenommenen Strohschicht kann die obere Kante der Abzugsöflnung 4 höhenverstellbar angebracht sein.desired value can be set. For this purpose, the shaft is provided with adjustable side walls 10. At the transition point between the upper fixed shaft part and the lower shaft part with its adjustable walls 10, elastic guide tabs 9 are attached.
In order to change the height h of the straw layer carried along by the conveyor belt, the upper edge of the extraction opening 4 can be attached in a height-adjustable manner.

Die vom Förderband mitgenommene Strohschicht der Höhe h und der Breite wird verschiedenen Arbeitsmitteln zur Gestaltung des Endproduktes zugeführt. The straw layer of height h and width that is carried along by the conveyor belt is fed to various work equipment for shaping the end product.

For this purpose, the design according to the invention can be seen while backwards through one of the straw in that for the discharge of the main part of the vent opening opposite shaft opening of the air flow in a manner known per se on the. or a branching compressed air escapes through the sieve-like conveyor belt through the upper part of the storage shaft, dadu rch geke nnzeich- air line is connected, into which the main network that for the derivation of the main part of the i ₅ part of the blower air flow exclusively under air flow in a manner known per se to the Effect of the back pressure in that under the upper part of the manhole (2) a branching part of the manhole is connected, in which the air duct (6) gives way, and that this branch duct is free, ie without the main part of the blower air flow excluding straw blocking screen the storage shaft is closed with a sudden change of direction under the junction of more than 90 ° under the effect of the damming resistance in the ₃ o borrowed direction and escapes to a larger collecting chamber shaft (2), and that this branch leads into which entrained dust and entrainment free, ie without a Strohsperrsieb, to the geri can knock down that piece of straw. A storage shaft with a sudden directional direction has shown that, surprisingly, only a change of more than 90 ° is connected and a small part of the conveyed straw leads into the branch to a larger collecting space in which the pipe is carried away while the main part is carried away with dust and straw that is swept away can be thrown down into the storage shaft and parts can be knocked down. by the damming effect of the air in the place of yours

Fig. 1 shows the device for feeding straw

The invention provides a device for closing a straw mat machine according to the invention

carrying straw for straw mat machines through 35 in the side view,

a blown air stream that pushes the straw through a F i g. 2 the device according to FIG. 1 in the front vertical storage shaft down to a conveying view and partially cut,
The straw is fed by a cutting fan, not shown in the drawing layer, through a side opening, which continuously pulls off the opening of the storage shaft, while the straw that is introduced is pulled backwards to the desired length one of the straw drawers cuts and through, a powerful air flow via opening opposite the shaft opening or a line I to a storage shaft 2, with compressed air through the sieve-like conveyor belt at the lower open end of the conveyor belt 3. escapes. Driving teeth is provided, which removes a lower order of suitable conveying speeds as a straw layer of a predetermined thickness h by also having a good pressing effect in the storage chute via the side opening 4 of the storage chute 2. Achieved by the conveyor belt, one has when producing one of the straw conveying opening 4 opposite places of mats made of other material, for example rear shaft opening 5, the air that penetrates up to the wood wool, as well as when conveying the lower end of the storage shaft, escapes from specific heavier goods, e.g. B. Fischen, 50 The main part of the conveying air is branched off in the upper part in the upper part of the storage shaft, the main part of the storage shaft 2 via a branch line 6-conveying and compressed air, whereby one led that at an acute angle "into the stowage -Take of conveyed goods through this branched off shaft 2 opens. The connection opening 7 prevents the stagnant air flow with the help of a blocking screen. The shaft is not blocked by a sieve, but the application of the same measure with the 55 is completely free. Due to the sudden change in direction, the production of straw mats has proven to be unsuitable for the main air flow at junction 6, because even after a short period of operation below this junction in storage shaft 2, the straw becomes clogged with a strong damming effect and it forms in the connection point the branch line, so that the storage shaft consists of a column 8 of pressed straw, of which the straw column in the storage shaft grows rapidly above the height h through the glass walls of the storage shaft branch. As a result, the press operation can be observed. The feeding of straw in the lower area of the storage chute to the cutting fan is regulated so that a possibly constant column of goods // in the storage chute 2 can no longer be maintained properly. The branch line 6 leads exercise. 65 in a larger buzzing room in which
