EP1266827B1 - Sandbag filling apparatus with agitator and at least 2 independent discharge chutes - Google Patents

Abstract

High-performance sandbag filling system comprises a forced mixing system and at least two independent sandbag filling pipes. The system has a supporting frame, a mixing drum with mixing teeth rotating inside, and sandbag filling pipe discharge chutes. Preferred Features: Each sandbag filling pipe discharge chute can be operated independently of the other sliders. The mixing teeth must rotate in the same direction as that in which the sliders are opened.

Description

The invention relates to a high-performance sandbag filling plant according to the preamble of claim 1, which can also be used as a mixing plant.

Flood catastrophes are becoming more common and increasing in intensity, with high demands being placed on sandbag filling plants which are best met by this invention. In the disaster emergency, the sand is usually wet, wet or sticky or mixed with soil or humus, which is not a problem for the invention of this sandbag filling plant. However, the prior art shows that previous sandbag filling machines work only with dry, free-flowing sieve sand, and that with a very low performance, and furthermore are very susceptible to pebbles and foreign bodies.

From CH-A-659052 a device for the portioned and metered delivery of bulk material is known. The device comprises a mixer drum with outlet openings arranged in the bottom of the drum, through which the bulk material is conveyed by means of mixer arms rotating within the drum. In order to avoid bridge formation at the outlet openings, they are not designed to be closable, but at a distance above each outlet opening, a respective cover protruding laterally is arranged.

From US-A-5740950 a device for filling bulk material is known, in which the bulk material is mixed in a box-shaped receptacle via rotating mixing blades and by a screw conveyor is transported to formed in the bottom of the receptacle outlet openings. The outlet openings open into filler neck, which are each closed at its lower end via pivoting flaps.

The object of the invention is to provide a high-performance sandbag filling system of the type mentioned in such a way that even moist and sticky sand can be processed smoothly and with high performance.

According to the invention, we have achieved this object by a high-performance sandbag filling system according to claim 1.

The system consists of a sturdy support frame, a drum located on it (round sand container) in which the rotating spring tine arms loosens the bulk material eg sand, mixes and transported outwards to the sandbag filling tube located all around. When opening the slide (Dreiviertelteller in the bottom of the drum) by turning the handle of the filling nozzle thus the bulk material is pressed into the filler neck and filled the suspended sand bag. At each filling system are at least 2, in this case 7 independently operable sandbag filling. The slide can be opened at will according to the filling performance. A hopper for loading the system with a front loader, wheel loader or excavator can be placed on the drum. The drive of the spring tine arms via a tractor or Unimog on the propeller shaft (PTO) or hydraulic, but can also be driven by direct drive such as electric motor.

• hohe Leistung, bis zu 3500 Sandsäcke/Std. mit 7 Abfüllstutzen.
• Sand in jeder Form ob feucht, nass, klebrig oder trocken. - nicht nur Sand, sondern Kies bis 30 mm Körnung und Splitt, Granulate und Baumaterialien können vermischt und abgesackt werden.
• auch Naturkies kann verwendet werden, wenn die großen Steine nicht zu viel sind.
• großer Einfülltrichter für mechanisches Nachfüllen.
• dass die Federzinken verstellbar sind, zum Mischen nach innen geneigt und zum Befüllen der Säcke nach außen geneigt werden können und dadurch die Verwendbarkeit und die Leistung enorm ansteigt.

The many advantages of the invention over the prior art are:

• high performance, up to 3500 sandbags / hour with 7 filling nozzles.
• Sand in any form whether moist, wet, sticky or dry. - Not only sand, but gravel up to 30 mm grain size and grit, granules and building materials can be mixed and bagged.
• Also natural gravel can be used if the big stones are not too much.
• large hopper for mechanical refilling.
• that the spring tines are adjustable, can be inclined inward for mixing and can be tilted outwardly for filling the bags and thereby the usability and performance increases enormously.

The grille on the Sandbagabstutzen-discharge chute can be advantageously designed such that they are pressed zhrem and tacky sand material and larger stones automatically from the sand material and thus no clogging takes place and no loss of time by cleaning or damage is necessary.

Due to the round shape of the mixer drum in combination with the mixer tines, gravel, grit and granules can also be mixed and filled for the construction trade and industry with little energy and low wear.

Claims (7)

1. A heavy duty sandbagging machine comprising a forced-action mixing system and at least two, for example seven, sandbagging nozzles, in particular for flood protection and civil protection, wherein the machine consists of a support frame rack, a mixer drum (6) located thereon, with a plurality of rotating mixer tines (19) located therein and discharge chutes (2) for the sandbagging nozzles located around it, for the filling of sandbags and for the mixing of loose material,
   characterised in that
   the sandbagging nozzles can be operated independently of one another;
   in that the discharge chutes (2) for the sandbagging nozzles are each provided with a slider (1) rotatably arranged in the base of the mixer drum (6);
   and in that each discharge chute (2) for the sandbagging nozzles can be operated independently of the sliders (1) of the other discharge chutes (2) for the sandbagging nozzles.
2. A sandbagging machine in accordance with claim 1, characterised in that the mixer tines (19) have to rotate in the same direction as the sliders (1) of the discharge chutes (2) for the sandbagging nozzles are opened.
3. A sandbagging machine in accordance with claim 1 or claim 2, characterised in that the loose material, like sand here, is pressed into the opening of the discharge chute (2) for the sandbagging nozzles.
4. A sandbagging machine in accordance with any one of the claims 1 to 3, characterised in that the filling performance or throughput amount can be increased by the opening width of the sliders (1) but also by the rotary speed of the mixer tines (19) and also by the number of the mixer tines (19).
5. A sandbagging machine in accordance with any one of the claims 1 to 4, characterised in that the mixer tines (19) yield to the rear or to the side so that a stone or foreign body which is too large and does not fit into the filling opening cannot cause any damage.
6. A sandbagging machine in accordance with any one of the claims 1 to 5, characterised in that sandbags of all types and sizes can be filled as desired without any conversion due to the conical merging of the discharge chute (2) for the sandbagging nozzles.
