Definitions

  • the invention relates to a device for the removal of conveyed material, at least compressed under storage pressure, from a feed stock, silo or compact from its approximately vertical end face using an approximately horizontally arranged in front of this end face and movable longitudinally and transversely to it guided support beam with longitudinal conveying drums and end cutters protruding from its front surface as well as lateral cutting units provided laterally on the outside and a conveyor device arranged transversely to the longitudinal conveying drums.
  • the support frame with the end cutting units usually being approximately perpendicular to the support surface from top to bottom is moved and in the meantime is moved into the feed stock by a feed distance, which can also take place continuously with the cutting process.
  • a feed distance which can also take place continuously with the cutting process.
  • a device of the type described above is known from German Offenlegungsschrift 24 35 137.
  • the longitudinal conveyor drums are designed as separating screws, the screw spirals of which also subdivide the material to be cut, which falls into a channel underneath, from which it passes through a channel transverse to the Longitudinal conveyor drums arranged on the screw conveyors are cleared away to the side and fed to a subsequent feed conveyor.
  • Cutting chains as are customary in hand-held chainsaws, serve as side cutters, and the supporting beam is designed in the manner of a flat frame which is held at a distance from a vertical guide and is raised and lowered along it.
  • the frame serving there as the supporting beam is not sufficiently rigid or even rigid for most clearing operations and is easily set in vibration if it is subjected to heavy loads, as is the case when ⁇ ech ⁇ cutting heads of the longitudinal conveyor drums and two chain saws are engaged. These chainsaws also have a relatively wide cutting profile, which causes large cutting forces.
  • the goods initially falling down are first cleared to the side and then transported obliquely upwards via the loading conveyor.
  • the chain milling machine requires space on the side by means of couplings or even individual drives. As a result, it is often not possible, despite the higher drive power, to mill uniform grooves in the end face of the chuck.
  • the supporting beam is not very stable in shape and is guided in a U-shaped rail, flat levers with cutting tips attached to their ends being used as the front and side cutting mechanism. That also falls there Well again on the floor, it is thrown up by means of a spiked shaft and pushed through a screw into the suction area of a blower, where it is finally thrown up through a separate shaft.
  • the structure used there is also bulky, not sufficiently stable in itself and not dimensionally stable, and is therefore susceptible to vibrations and malfunctions. It is also relatively complex even if it is detachably attached to a tractor or another motor vehicle.
  • DE-A 36 02 403 discloses a stripping device which has two conveyor belts connected in series on a trailer frame, the receiving belt having two side cutting units formed by circular knives and the face cutting unit two mutually longitudinally oscillating knife blades in the manner of gang saw blades has. These are guided on the vertical wall of an angular housing cover which is placed on the outer part of a guide channel for the conveyed goods which have been separated.
  • the blades of the knife reach much deeper than the saw-toothed circular knives of the side cutters.

  • the invention is based on the ablation device defined at the outset and pursues the task of developing this device in the simplest and most economical way so that an ablation unit which is to be moved along the end face of the chuck is possible to be compact, rigid and rigid, that is to be conveyed is detached with a small drive line and can be brought into a receiving space with small deflections.
  • the device used to solve this problem is characterized in that the supporting beam is formed by a central, rigid bearing box, on the upper side towards the front side a transverse drum spanning the longitudinal conveyor drum or two drums is mounted, which supports the individual predominantly radially protruding, continuous or interrupted conveying elements (blades) and covered with the longitudinal conveying drums by a protective hood, which has an outlet opening towards the rear of the device for the further conveying of the conveyed material which has been triggered and flung out from the feed stock.

  • the material is thrown up in the groove thus predefined and gripped by the longitudinal conveying drums, raised into the engagement area of the transverse conveying drum and conveyed through this directly to a receiving space.
  • the box-shaped design of the supporting beam as a central storage box makes it relatively dimensionally stable.
  • the connection points for the various machine tools and conveying units are so far apart that they do not adversely affect one another, so vibrations are largely eliminated. Therefore, igly thin tools or cutting knives meet the required stiffness.
  • the cutting units used here can be designed in various ways, which sometimes results in considerable vibrations and often cuts or cuts more material than is necessary for the separation function and thus the lateral free cutting for the front or the central front cutting units .

  • the blade is preferably wedge-shaped and is wavy on both sides so that the likewise wavy cut edge runs in the central plane of the blade.
  • this is remedied by a device which relieves the operator of observing the intervention and deciding on the speed and depth of the advance or intervention in the pressing body to be removed.
  • This device comprises a switching device and a button connected to it for scanning the distance between the front cutting unit and the front surface of the chuck, the switching device triggering a signal when the specified distance is undershot and thereby notifying the operator that he is doing this End tools must not move further into the end face of the chuck.
  • an automatic safeguard can also be installed in such a way that the feed device, for example the right of way of a tractor or similar carrier vehicles, is temporarily blocked by means of the signal mentioned. In this way, excessive stresses on the components subject to the feed force are avoided.

  • the transverse conveyor drum (5) of the discharge device (60) is mounted above the bearing box (1) and the longitudinal conveyor drums (2) by means of its shaft (22) in the side walls (45) of the protective hood (4), the lower edge of which is tight and rigid with the Storage box (1) is connected.
  • the shaft (22) is driven by the main shaft (16), each with a chain step (80) provided at its two ends, the axial webs (85) arranged on the drum jacket taking over the function of tangential fan blades.
  • Two chain stages (180) serve to drive the lower transverse conveyor drum (95).
  • the outer edge of the protective hood (4) is designed such that the distance between this outer part and the transverse conveyor drum (5) reaches a minimum approximately in the extension of the chain step (80). This also results in a briefly increased contact pressure and thus a correspondingly strong acceleration in order to throw material conveyed upward by the longitudinal conveyor drums in the hood through the outlet opening (81) in the direction of the arrows (82) into the loading space of the loading wagon .
  • a second cross conveyor drum (95) of a second discharge device (111) is mounted in lateral webs (112) on the underside of the storage box (1). This discharge device serves primarily to pick up and further convey the conveyed goods that have not been grasped by the longitudinal conveying drums (2) or have not been properly conveyed further, they also increase the total discharge line.
  • the further conveying takes place in the operating positions I and II in that the material is sucked in from the direction below the longitudinal conveying drums (2) and is carried out in a straight line between the lower transverse conveying drum (95) and the underside (29) of the bearing box (1) and thereby nozzle-like accelerated in a predominantly horizontal plane and is introduced directly into the upper opening (56, 57) of the loading wagon (47), which is also bevelled on its front side.
  • the lever arm of the fork arm (48) to the removal unit (49) is designed so that the arc path of the removal unit is designed such that the two conveying flows (113, 114) lead in the entire swivel range into the open receiving space of the loading trolley (47).
  • the two currents approach each other towards the loading wagon, so a single widespread flow can arrive there. In this way, delivery losses are reduced to a minimum.
  • the bottom housing (115) of the conveyor screw (116) of the loading wagon (47) sits with one free end on the bottom (52) and thus protects the end cutting knife (43) just like the second transverse conveyor drum (95 ) with their axial webs (85) before contact with the ground.
  • This does not exclude that support elements are attached directly to the storage box (1) or also to the side walls (45) of the protective hood (4) which may need to be made strong.
  • the transverse conveyor drum (95) is surrounded on three sides, namely opposite the storage box (1), the floor housing (115) and the floor (52) by three conveyor channels narrowed in the manner of a nozzle. Its scope is practically only connected to the space below the longitudinal conveyor drums (2).
  • FIG. 16 contains a modification in so far as the cover (21) is replaced by a narrower cover (211) which essentially only covers the upper part of the rear of the bearing box (1), while in the lower part a sloping strut plate is used (212) moved in.
  • the cover (21) is replaced by a narrower cover (211) which essentially only covers the upper part of the rear of the bearing box (1), while in the lower part a sloping strut plate is used (212) moved in.
  • the circulating flow of the bearing box (1) is improved on the one hand, and on the other hand its torsional rigidity is increased.
  • One of the two transverse conveying drums can also be used to approach the end face (9) of the feed hopper (10) in order to obtain a position for the initial cut without requiring special means. If the axial webs (85) do not want to be subjected to any abutment force, it could also be provided to the side of the drum jacket flange that can absorb greater compressive forces, especially since they are located close to the bearing.

Abstract

Une unité de retrait mobile (49) pour retirer du stock de transport d'un stock de fourrage, d'un silo, ou d'une presse ou semblable comprend une boîte de stockage (1) pouvant être fixée par deux bras de raccord à l'extrémité libre d'une flèche de grue en forme de fourche ou à la fourche d'allongement d'un tracteur. Ladite boîte peut ensuite se déplacer en descendant sur une piste courbée le long de la surface avant du stock de fourrage. Les mécanismes de coupe latérale (6) sont dotés de lames (61) pour faire des coupures latérales verticales de manière à détacher les bords d'une bande parallélépipède du stock de transport, que fraisent les couteaux de coupe de front (44). La matière est ensuite jetée par des saillies (37, 38) de tambours de transport longitudinaux (2) dans la zone d'entrée d'au moins un tambour transversal (5), d'où elle est émise à travers une ouverture d'expulsion (81). Les lames (61) qui sont munies d'un coupeur ondulé (76), oscillent autour d'un axe transverse pivotant. Dans une réalisation préférée, un deuxième tambour de transport est disposé en-dessous du tambour de transport longitudinal au fond de la boîte de stockage d'engrenage de sorte que, lorsque ladite boîte se place sur la base, un écoulement de transport envoyé par des buses est déversé autour du tambour de transport transverse inférieur, ainsi doublant la capacité du transport.
