Description

When removing the stored in the pre-herd cat food it is primarily important to achieve high cutting and thus removal performance with minimal cutting resistance, with the support frame with the end cutters usually about vertically moved from top to bottom to close to the support surface and in the meantime order a feed line is moved into the feed & tock, which can also be done continuously with the cutting process. To increase the cutting performance on the main cutting surface, ie in particular in the face cutting plants, a pre-cutting or lateral relief is recommended by separate side cutting machines.

State of the art

A device of the above-described type is known from German Offenlegungsschrift 2435137. The longitudinal conveyor drums are formed as Abschnechenschnecken whose screw helices also cause a subdivision of the cut material, which falls into a channel below it, from which it is arranged by a transversely to the longitudinal conveyor drums arranged screw conveyor Side away and fed to a subsequent feed conveyor. As cutting sideways serve cutting chains, as are common in hand-held chainsaws, and the support beam is formed in the manner of a flat frame, which is held at a distance from a vertical guide and lifted along this and lowered.

The frame serving as a support beam is not sufficiently rigid or even rigid for most clearing operations, and is easily vibrated when subjected to heavy load, as is done by six cutting heads of the longitudinal conveyor drums and two chainsaws. These chainsaws also have a relatively wide cutting profile, which causes correspondingly large cutting forces. The initially falling down Good is first cleared to the side and then transported over the feed conveyor obliquely upwards. In addition, the drive of the chain cutter requires lateral space through couplings or even individual drives. As a result, it is often not possible, despite the higher drive power, to mill uniform grooves in the face of the foodstuff.

Also in the removal device according to FR-A 2496413, the support bar is formed less dimensionally stable, which is guided in a U-shaped rail, being used as a front and side cutting flat actuators with attached at their ends cutting tips. Also there, the good falls back to the ground, is thrown by a spiked shaft and pushed by a screw in the intake of a fan, where it is finally thrown up by a separate shaft.

Also, the structure used there is bulky, not sufficiently stable in itself and not dimensionally stable, therefore prone to vibration and malfunction. It is also relatively expensive even if it is releasably attached to a tractor or other motor vehicle.

Finally, DE-A 3602403 a removal device is known which comprises two conveyor belts connected in series on a trailer frame, wherein the recording tape has two side cutters formed by circular knives and the front cutter two mutually längsschwingeiide knife blades in the manner of gate saw blades. These are guided on the vertical wall of an angle-shaped housing cover, which is placed on the outer part of a guide channel for the separated conveyed. However, the knife blades reach much deeper than the sawtooth circular blades of the side cutting machines. It is therefore not the first cut laterally cut Good, but it must be fully cut on the length of the blades in the still compact material before it is separated laterally. The applied drive power is thereby unnecessarily increased. In addition, the cross-sectionally triangular hollow support beam has only a small load-bearing cross section and in turn is susceptible to vibration and deformation, especially since the cutting force is introduced there at the free end of a boom formed by the first conveyor, which is about a rear axis at the end face of the Feedstocks is swung along.

Summary of the invention

The invention is based on the removal device defined above and pursues the task of developing this device in a simple and inexpensive way so that a on the end face of the feedstock to be moved along Abtragage unit is compact, stiff and rigid, the conveyed detached with less power and can be brought into a receiving space with little deflection.

The serving to solve this problem device according to the invention is characterized in that the support beam is formed by a central, dimensionally stable storage box, at the top to the front side offset a longitudinal conveyor drum or drums spanning transverse drum is mounted, the single predominantly radially projecting, continuous or has interrupted conveyor elements (blades) and is covered with the longitudinal conveyor drums of a protective hood, which has an outlet opening for the further promotion of the triggered and thrown from the feedstock conveyed to the back of the device.

Here, after the pre-cutting of the lateral groove surfaces and the separation of the material to be conveyed in the so-defined groove aas well thrown up and detected by the longitudinal conveyor drums, raised in the engagement region of the transverse conveyor drum and further promoted by this directly to a receiving space.

Due to the box-shaped design of the support beam as a central storage box this is relatively dimensionally stable. The connection points for the various machine tools and delivery units are so close to each other that they do not affect each other adversely, so vibrations are largely eliminated. Therefore, even relatively thin tools or cutting blades can meet the required dimensional stability. In principle, there are only two fluids, namely the Längsfördertrommoln, which subtract the separated material from the interface, and the cross-conveyor drum, which provides the further transport.

The reapers used in this case can be configured in various ways, which is sometimes considerable

Vibration brings with it and many times more material cuts or machined than for the separation function and thus the lateral free cutting for the or the central end cutting is necessary.

Therefore, it is also an object of the invention to make the side cutting so that they affect the function dos or the end cutting as little as possible and even apply relatively large cutting performance to relieve the Strinschneldwerke.

For this purpose, according to the invention, the side cutting units are provided with oscillating, drivable, rigid blade blades mounted along both sides of the longitudinal conveyor drums.

Such blades, even when they are pulled, have a low cutting resistance, which becomes smaller the more the driving force pulsates or oscillates. The oscillating movement has the advantage that the direction of movement is constantly changing, with the pulling section predominating. Exceptionally high cutting performance with low cutting forces is possible on this catfish with low cutting resistance.

As a result, all supporting facilities, especially the tubular storage box, only slightly claimed. The executives for the entire removal unit are smaller than those in conventional removal devices. Therefore, it is basically sufficient to attach to a standard suspension of a tractor or crane vehicle or at the free end of a swing-up boom to achieve a smooth smooth cut. With regard to the removal performance, the production cost is also low, since the transverse drum responsible for the further conveyance can serve a large number of longitudinal conveyor drums.

At least one of the blade blades should be mounted in a transverse to its plane pivot axis. Preferably, it has the basic shape of a flat right triangle, which is pivotally mounted at the upper corner and connected to the adjacent lower corner of a vibratory drive, such as an eccentric or connecting rod drive. At least one blade may have a lower cutting edge, which is guided in the leaf center plane from a pivoting center position approximately symmetrically to both sides swung out. It can have a serrated edge with the same or different wavelengths and / or shapes.

Preferably, the blade blade is wedge-shaped and wavy ground from both sides so that the also wavy cutting edge extends in the leaf center plane.

The intervention of the front and side cutting units on the front side of a foodstuff can be observed in the removal process by the operator in a very inadequate manner. He therefore can not reliably judge how far the removal unit can still be advanced without overburdening the cutting units, possibly blocking. To remedy this serves a device according to the invention to relieve the operator in the observation of the intervention and the decision on speed and depth of the propulsion or engagement in the ablated compact. This device comprises a switching device and a connected to this button for scanning the distance between front cutter and face of Futtorstockes, the switching device falls below a predetermined distance triggers a signal and thereby makes the operator aware that he does not continue the front tools in the face of the feedstock may enter. In principle, an automatic backup can be installed in such a way that by means of the mentioned signal, the feed device, such as the right of way of a tractor or similar carrier vehicle is temporarily blocked. In this way, overstressing of the components subject to load by the feed force can be avoided.

Such blades, even when they are pulled, have a low cutting resistance, which becomes smaller the more the driving force pulsates or oscillates. The oscillating movement has the advantage that the direction of movement is constantly changing, with the pulling section predominating. In this way, exceptionally high cutting performance is possible with low cutting resistance and low cutting forces. As a result, all supporting facilities, especially the tubular storage box only slightly claimed. The executives for the whole / .btrageeinheit are smaller than those in conventional Abtragevorrichtr -.gen. Therefore, it is sufficient in principle to attach to a standard suspension of a tractor or motor vehicle or at the free end of a swing-arm so as to achieve a uniform smooth cut. With regard to the removal performance, the production cost is also low, since the transverse drum responsible for the further conveyance can serve a large number of longitudinal conveyor drums.

At least one of the blade blades should be mounted in a transverse to its plane pivot axis. Preferably, it has the basic shape of a flat right triangle, which is pivotally mounted at the upper corner and connected to the adjacent lower corner of a vibratory drive, such as an eccentric or connecting rod drive. At least one blade may have a lower cutting edge, which is guided in the leaf center plane from a pivoting center position approximately symmetrically to both sides swung out. It can have a serrated edge with the same or different wavelengths and / or shapes.

Preferably, the blade blade is wedge-shaped from both sides wavy ground so that the also wavy cutting edge extends in the leaf center plane.

The invention further relates to a device for removing at least under bearing pressure compressed conveyed from a feedstock, silo of the compact from its approximately vertical face ago using a front cutter, at least one Längsfördertrorrrnel and two laterally arranged side cutting units, which is characterized by a switching device and a connected to this button for scanning the distance between front cutter and end face of the feedstock, the switching device when falling below a predetermined distance triggers a signal and thereby makes the operator aware that he must not retract the front tools in the face of the feedstock. In principle, an automatic backup can be installed in such a way that by means of the mentioned signal, the feed device, such as the right of way of a tractor or similar carrier vehicle is temporarily blocked. In this way, overstressing of the components subject to load by the feed force can be avoided.

In order to remove the feedstock gradually from the front side, the support of the firing device with the end cutters, usually in an arc about vertically moved from top to bottom to just above the ground, then raised, laterally to the last cutting path and turn in current cutting units moved down until the predetermined feed depth step by step, a whole layer is removed from the face.

In this way, the main cutters are relieved, so that the removal rate could be significantly increased. At the high working speed, however, part of the already collected and stirred up goods were not completely fed into the feed room.

In order to remedy this, to further increase the cutting and removal performance and to bring reliably all detached and deducted from the feedstock Gut in receiving space, according to the invention below the longitudinal conveyor drums another firing device attached, which does not or insufficiently detected by the longitudinal conveyor drums conveyed after a Futteraufnahmeraurr · on ,

This zvvnite firing device thus serves once to resume the uncontrolled falling of the cutting units and optionally the longitudinal conveyor drums Good and continue to promote. On the other hand is now the capacity of two Abfördsreinrichtungon available, which serve the common purpose to supply the good after the separation of its further use, ie in particular to promote it in this particular receiving space, usually in the hold of an agricultural wagon.

Conveniently, the lower firing device as well as the upper is equipped with a cross-conveyor drum, which is carried out along its axis of rotation and / or interrupted conveyor blades, which may be formed by at equal pitch angles on the lateral surface of the transverse conveyor drum mounted axial webs. Both transverse conveyor drums can be connected to a common drive device having a parallel to both transverse conveyor drums main shaft, from which the drive for front and side cutting is derived.

The cross conveyor drums set here are characterized above all by their throwing power over even greater distances, so that the trajectory of both discharge devices can be directed to the loading space of a transport vehicle from virtually all occurring altitudes of the removal device.

In order to produce a high-speed DUsenströmung with the lower firing device, the lower transverse conveyor drum is advantageously mounted between lateral webs on the gearbox storage box at a distance from the bottom and further promoted the good to dioser bottom along a nozzle.

If the lower transverse conveyor drum is in its lowest position when the removal device is seated on the floor, it has approximately the same distance to the floor and to an end face of the loading carriage as from the underside of the gearbox storage box. The nozzle delivery flow is deflected around the transverse conveyor drum up to the longitudinal conveyor drums.

It can also be the lower Querfördertrommol be used as a contact button or traction on the face of the foodstuff, so that separate scanning devices and controls can be omitted. Now the performance of the discharge is dependent on the feed rate of the goods, that is, on the output speed of the longitudinal conveyor drums. To increase this speed, preferably from the circumference of the longitudinal conveyor drums outwardly projecting and identically formed mandrels are arranged with the same circumferential pitch and at the same axial intermediate distances in rows along generatrices of the longitudinal conveyor drums. In this way langfaserigeres and other good can equally detect and acceleration Λ weitergeförd be. Although it is initially thrown tangentially, but the axial acceleration has previously been applied by the Schi aidmessern.

The greatest centrifugal force can be applied when the rows of mandrels are arranged laterally adjacent conveyor drums so that they each meet in groups in the same axial plane at intervals, which are smaller than a half row longitudinal pitch of the mandrels.

A further increase in cutting and Abförderleistung can also be achieved by the fact that the orbits of the cutting blades extend beyond the cutting planes of the Seitenscheidwerke, ie einformen in the grooves to be milled feedstocks transverse waves, further reduce the relationship and thereby reduce the cutting forces. Likewise, it serves to increase the cutting performance when the end cutters and the side cutters engage to about a same level in the feedstock.

Further embodiments and advantages of the invention are set forth in the dependent claims and in the subsequent explanation of the invention with reference to the drawing.

Detailed description of preferred embodiments of the invention

Still the illustration Fig. 1, the removal device consists essentially of a loader wagon (47) with a hochschwenkbaren fork arm (48) which carries at its free end a Abtrageeinheit (49) by pivoting up and down of the fork arm (48) on the circular arc-shaped end face (9) of the feedstock (107 is guided along and these milled to the second part end face (91) at an engagement depth (t).

The loader wagon (47) is here designed as a trailer vehicle, which travels a towing vehicle, in this case a tractor (46), and is driven and held in the reverse direction (r) in engagement with the end face. The pivotable in the side bearings (50) boom is pivoted by two lateral hydraulic cylinders (51).

The milling can be done in stages such that at a fixed setting of Ge clamping (46,47), the removal unit (49) at a constant depth of engagement (t) down to close to the bottom (52) is moved. In this way, the procedure can be kept fairly constant.

It is more difficult to cut simultaneously when driving and swiveling down the boom (48), which then results in a spiral-shaped partial end face (91). In principle, it is also possible to connect the pivoting movement with the driving movement mechanically or by electronic coupling in order to follow up a corrected end face (91), which, in principle, can be designed as desired.

Since the team leader during the milling process and also when driving in the feedstock (10) the view is concealed on the job, a later to be described scanning device was provided, the dsm team leader by a signal lamp (93) indicates when oin predetermined distance of the Abtrageeinheit ( 49) is reached from the end face (9), wherein at the same time, possibly also automatically, the traction drive switched off and the vehicle can be braked.

At the top side (56) and front side (57) the trailer wagon (47) lacks final windings. It can therefore on the whole pivoting the Abtrageeinheit (49) insert the milled feed directly into the loader wagons (47).

Carrying part of the illustrated Abtrageeinheit (49) is an elongated cuboid bearing box (1), the four projecting from its front (11) longitudinal conveyor drums (2) and on its upper side (12) obliquely rearwardly projecting connecting arms (3) and a .schutzhaube (4) and by means of this in the side walls about its axis (84) rotatably mounted transverse conveyor drum (5) carries. On both side surfaces (13,14) of the storage box side cutters (6) and sensing devices (7) are mounted, the latter each the distance of the longitudinal conveyor drums (2) mounted side cutting units (8) of the end face (9) of a feed silo or the like ( 10) and control a signaling device, such as with the lamp (93), or shutdown direction when a predetermined distance is exceeded.

In the interior of the storage box (1) according to Figure 3, a drive device (15) is mounted, which is operated by a drive motor (M) and by means of its main shaft (16) the individual longitudinal conveyor drums (2) with the end cutting units (8) and the Side cutters (6) and the transverse drum (5) drives.

The storage box (1) has the shape of a welded together steel plates tube, the open back (19) is closed by a screwed lid (21). This cover carries inside in a molding (17) the drive motor (M), which drives a main shaft (16) via a pair of spur gears (20) in the two side walls (13,14) and to both ropes of the spur gear pair (20) Web walls (23) is mounted.

On the main shaft (16) sit four pinions (24) which engage in ring gears (25) of four bevel gear (26). In this case, each bevel gear sits on the inner end of a longitudinal drum shaft (27) whose outer end is fixedly connected to the longitudinal conveyor drum (2), in particular welded. This drum is essentially formed by the drum shell (28), a front disc (31) and a central disc (33).

For storage of the longitudinal conveyor drum is a possibly cup-shaped flange (34), which is externally screwed to the front (11) of the storage box (1) and to both ends towards double roller bearing (35) for a drum dome (27) receives.

On the circumference of the longitudinal conveyor drums, radially outwardly projecting mandrels (37) and blades (38) are distributed in, for example, helices. The mandrels (37) have the shape of a slender cone and extend into an outer Hüllzylinderfläche (39). In contrast, the blades (38) protrude only into a narrower enveloping cylinder surface (40).

As can be seen in particular FIGS. 4 and 7, mandrels (37) and blades (38) alternate with two or more helical grooves on the circumference of the drum. The mandrels (37) are primarily used for detecting fibrous material, the blades (38) for further promotion kurzfaserigen or compact material to be conveyed. Depending on the nature of the material to be conveyed, the number of spikes and blades can be selected, that is, in the case of exclusively long-fibered material, it is possible in principle to work only with spikes, if appropriate with short-fiber material only with blades (38).

3 shows that adjacent longitudinal conveyor drums (2) rotate in opposite directions. Between the axes (I, II and III, IV) is thus promoted according to the marked arrows (o) upwards, outside and between the axes (II, III) down (u).

In order to facilitate this spinning or even further conveying, the side surfaces (41) for grooves (42) to be milled into the end face (9) of the feedstock (10) are first pre-cut by the Soitenschneidwerke (6). Then it is traced with the end cutters (8) to replace the at least laterally separated Good from the feedstock. At the existing end face (9) while the stepwise recessed second part end face (91) is formed.

The end cutting units (8) each have two diametrically opposed end cutting blades (43), which are fastened interchangeably with their inner part (43a) on the end disk (31) close to their outer edge, in particular screwed. The outer part (43 b) of the end cutting blade (43), however, wound around the periphery of the front disc (31) propeller-like and ground at its edge in the circumferential direction edge to form a cut edge (44). The polished section should follow from the axial front.

As already evident from FIG. 2, the circulation circle (54) of the face knife (43) is brought close to the blade (61), but also to the drum shell (28) of the adjacent longitudinal conveyor drum (2). From Fig. 3 there is the distance (e) in the order of about 2 to 3cm. It can therefore be cut very close to the respective lateral processing limits.

The side cutters (6), as best seen in Figures 4 and 6 to 9, each have a substantially planar, rigid blade in the form of a right triangle with about 30 degrees of apex angle formed by a rolling bearing (62). on the shank (63) of a cap screw (64) is mounted, the screw head (65) is designed as a circular disc with a diameter which has approximately four to eight times the diameter of the screw shank (63). The flat screw head (65) presses via a thrust washer (66) made of bearing material on the outer surface of the blade blade (61 /, which in turn rests with its inner surface on an abutment plate (67) made of bearing material, which by means of countersunk screws (68) on the side wall ( The head screw (64) is also firmly screwed into this side wall and secured in a suitable known manner, so that outside of the roller bearing (62) a large-area and thus reliable clamping of the blade blade (61) of Screw head (65) to the side wall (18) achieved.

The thus formed pivot bearing, which is kept out of the cut area anyway, is stable in bending and forms a reliable clamping for the upper rear part of the blade blade (61). Under bearing material here are mainly non-ferrous metals or non-ferrous · or light metal alloys, eg. B. bronzes understood.

The blade (61) is driven by a connecting rod (72) which is connected at its lower end by a hinge (73) to the Rückceitige lower end of the blade blade (61) and the upper end rotatably mounted on an eccentric disc (74). In this way, the blade blade (61) constantly performs pivoting movements, which is superimposed on an oscillating translational movement.

On the underside of the blade blade (61), a wave-shaped cutting edge (76) is formed in the sheet central plane (75), which is formed by troughs (77) ground in opposite directions longitudinally and transversely symmetrically or asymmetrically or with changing wavelength or shape such that the cutting edge (76) remains constantly in the sheet center plane (75). This creates a constant change of cutting direction and force along the entire cutting length, which allows a low-resistance cut. In addition, the blade (61) despite its stiffness is so thin that the cutting resistance is very low overall.

As can be seen especially in FIG. 6, the blade blades (61) reach noticeably deeper than the front cutting blades (43) in the two-blade cutting device used there. Since they are also arranged below the common longitudinal middle planes (79) of the individual longitudinal conveyor drums (2), the two types of knives do not interfere with the oscillating movement of the blade blades, that is, the feed material along the side surfaces (41) of the milled groove ( 42) clean and smooth and can immediately from there, in particular from the circumference of the longitudinal conveyor drums (2) arranged thorns (37) and blades (38) detected and further promoted. In this way, the stored material can be cut to close over a support surface.

In the two-axis Abtrageeir.heit of FIGS. 6 and 7 run again both longitudinal conveyor drums in opposite directions, that is, from the middle room, the food is conveyed almost vertically up and pressed down in the lateral area where it may be intercepted and fed to the extending part can be.

On the other hand, it can be seen above all from FIG. 7 that also there the blades (38) and the outwardly projecting twisted parts of the end cutting blades (43) are set opposite to the direction of rotation. As a result, an increase in the radial discharge effect compared to the axial further promotion is achieved.

The increase in the radial throwing effect also serves to bring the projections, ie mandrels (37) and blades (38), each close to the circumference of the neighboring drum. In this way, the weiterzufördernde Good in the middle plane between the two longitudinal conveyor drums for a short time is strongly compressed and thus brought almost instantaneously to the rotational speed of the drum shell. However, while the distance between the drum projections and the adjacent drum shell is approximately 5 cm, the end cutting blades (43) are circumferentially brought up to a much smaller distance (e) of about 3 cm radially to the drum outer surface, which in turn the comminution effect entgerger comes.

The transverse conveyor drum (5) is mounted above the storage box (1) and the longitudinal conveyor drums (2) in the side walls (45) of the protective hood (4) whose lower edge is firmly and rigidly connected to the storage box (1).

It is driven by the main shaft (16), each with one provided at its two ends chain stages (80), wherein the arranged on its jacket axial webs (85) take over the function of tangential fan blades. The webs may pass through one end of the drum t 'in the other, but also be interrupted in a regular or irregular manner and / or offset from each other in the circumferential direction. Their inclination to the drum axis can change along this drum axis, approximately symmetrically to a transverse center plane such that the conveyed to the transverse center plane out more together or is led apart.

The axial webs (85) or other comparable guide or conveying elements should be as metallic as possible. You can expediently be provided with fixed or replaceable mounted edge strips of elastically deformable material such as rubber or rubber-elastic plastic.

The outer edge of the protective cover (4) is designed so that the distance between this outer part and the transverse drum (5) reaches a minimum approximately in extension of the chain step (80). Also, a short-term increased pressure force and thus a correspondingly strong acceleration is achieved in order to throw the good conveyed by the longitudinal conveyor drums in the hood up through the outlet opening (81) in the direction of the arrow (82) in the loading space of the loading wagon.

As can be seen from Figures 2,4 and 5, at the rear of the storage box (1) at the level of the bottom thereof is a longitudinally extending along the transverse drum; Plate (86) attached to the outer edge in a joint (87) a touch plate (88) is mounted, whose lower edge (89) is bent back in the manner of a gutter. This touch plate (88) can, as the illustration in FIG. 5

from the initial position (a) via the intermediate positions (b) and (c) are pivoted to a maximum until in the end position (d).

It is loaded by a compression spring (90) located on a measuring rod (101) between one provided on this Stop (92) and an angle piece (96) is supported, which carries a switch (97) with a switching roller (98). The angle piece (96) is rotatably mounted on a tube (100) which is welded to the bearing box (1). The to operate the Roller (98) serving slide (99) Can be detected by a wing nut (102). It can be set before starting the milling job

be after a predetermined depth of engagement, an actuation of the switch (97) and thus enable switching on the lamp (93) or other signal or Steterelemente.

To set the switching point, the Tastplatto (88) in the Bodenstollung free from the feedstock from the position (a) so far

back to (b), (c) o. Like. Pivoting that a certain angular distance or linear distance to the position (a) remains. Then, the slider (99) on the measuring rod (101) is pushed into the release position and detected. This ensures that is always triggered when the predetermined distance is reached.

In this way, the operator can steer the vehicle on the short rectilinear backward path, when

it is ensured that a signal sounds before an important part of the vehicle, in particular a longitudinal conveyor drum (2) reaches the end face (9).

That is, Abtrageelnholt (49) shown in Figures 13 to 16 is provided with an upper and a lower discharge device (60 or

111), each having a transverse conveyor drum (5 or 95).

The loader wagon (471) is fully open at the top (56) and at the front (57) it is separated only by two End plates (54,55) completed. The stepped surface (58) formed therebetween also remains open. This way you can

be loaded continuously on the entire pivoting of the fork arm (48) of the loader wagons.

Inside the storage box (1) is a driven by a drive motor drive device with a Main shaft (16), which the individual longitudinal conveyor drums (2) with the end cutting units (8) and the Rare cutting units (6) and the two discharge devices (60,111) with their two transverse conveyor drums (5.95) drives. The storage box (1) is closed by a lid (21). The in the side surfaces (13,14) mounted main shaft (16) drives

via four pinions (24) by means of ring gears (25) and drum shafts (27) carried by these longitudinal conveyor drums (2). their

Drum shell (28) is on the cutting side by an end plate (31) completed. On the circumference of the longitudinal conveyor drums (2) diametrically opposite two rows of mandrels (37) are mounted. this

are on the adjacent longitudinal conveyor drum two such rows of mandrels assigned such that in each case after 90 degrees

Rotation of the two drums moving in opposite directions of rotation, two rows of corrugations moving in the same direction (37)

go through the axial plane together.

To make this possible, the longitudinal pitch of the mandrels is about twice as large as their largest diameter. The free gap

between opposing encountered thorns is therefore slightly smaller than this largest mandrel diameter. In this way, the conveyed between the spines of the adjacent longitudinal conveyor drums (2) can be reliably detected and accelerated almost instantaneously to a high rotational and spin speed. This makes it possible, on the whole adjustment path of the removal device (59) between the positions I and IM, the goods almost completely in the

To bring in the receiving space of the loading wagon. The mandrels (37) have the shape of a slender cone and extend into an outer Hüllzylinderfläche (39). You can

to absorb and feed virtually all food that comes into consideration.

The end cutting blades (43) have here substantially triangular shape and are with their wide inner part (43 a)

by means of screws (105) on the longitudinal conveyor drums (2) or their end plate (31) by screws (105) attached. They are slightly convex towards the feedstock and are provided with a wide polished section (106) from the curvature side to the cutting edge (44). The radially outer part (43b) is not quite pointed, so that no longer must be reground.

As can be seen in particular Figure 17, the side surfaces (41) in the groove to be milled (42) by blade blades (61) of Side cutters formed, which penetrate practically as deep as the front cutting blade (43) in the feedstock (10). These

However, cut into the flat side surfaces (41) cylinder segments (107), this loosen up and leave up and down each flat ribs (108,109) are. For these flat ribs is thereby through the incisions in the

Cylinder segments (107) of the cohesion to the feedstock (10) already partially solved what the detachment when cutting the

relieved adjacent groove and reduces the now required cutting work.

The circulation circuit (36) of the end cutting blade (43) is here twice as large as the drum diameter and close to the Back of the blade blade (61) along. The transverse conveyor drum (5) of the discharge device (60) is above the storage box (1) and the longitudinal conveyor drums (2)

by means of its shaft (22) in the side walls (45) of the protective hood (4) mounted, the lower edge fixed and stiff with the

Storage box (1) is connected. The shaft (22) is driven by the main shaft (16), each with one provided at its two ends chain stages (80),

wherein the arranged on the drum shell Axialstege (85) take over the function of Tangentialgebläseschuufeln.

To drive the lower transverse conveyor drum (95) serve two chain stages (180). The outer edge of the protective cover (4) is designed so that the distance between this outer part and the transverse conveyor drum (5)

approximately in extension of the chain stage (80) reaches a minimum. Also a short-term pinched pressure and thus a correspondingly strong acceleration is achieved in order to throw the good conveyed upwards by the longitudinal conveyor drums in the hood through the outlet opening (81) in the direction of the arrow (82) into the loading compartment of the loading wagon.

A second transverse conveyor drum (95) of a second discharge device (111) is in lateral stegon (112) at the bottom of the Storage box (1) stored. This firing device serves primarily to convey that conveyed by the Longitudinal drums (2) has not been detected or improperly further promoted, record and

Furthermore, it increases the total output.

The forwarding takes place in the operating positions I and Il characterized in that the good from below the direction Longitudinal conveyor drums (2) sucked and directly in a straight line between the lower transverse conveyor drum (95) and the Bottom (29) of the storage box (1) performed while nozzle-like accelerated in a mainly horizontal plane and

is introduced directly into the upper opening (56,57) of the loading wagon (47) which is still bevelled on its front side.

The lever arm of the fork arm (48) up to the Abtragelnholt (49) is so bomessen and the sheet web dor Abtrageelnhoit designed so that the two flow rates (113,114) In the entire pivoting range in the open receiving space of the loading wagon (47) lead. Conveniently, the two flows approach otwas to wagons back, so can arrive there as a single vorbrelteto flow. In this way, production losses are reduced to a Kloinstmaß.

As shown in FIG. 16, once the bottom housing (116) of the screw conveyor (47) of the loading wagon (47) rests with its froien end on the floor (52) and thus protects the front cutting blade (43) as well as the second transverse conveyor drum (95) with their axial webs (85) before Bodon contact. This does not exclude that directly on the bearing box (1) or on the side walls (45) of possibly strong to be designed protective hood 64) supporting elements are mounted. On this catfish, the transverse conveyor drum (95) on three sides, namely opposite the bearing box (1), the bottom housing (115) and the bottom (52) surrounded by three nozzle-like constricted conveying channels, their circumference is practically only with the space below the longitudinal conveyor drums (2) connected. This has the consequence that in the circumferential direction after this opening to the longitudinal conveyor drums, the pressure rises and below the Längsfördt-rtroinmeln drops. Thus, feed is almost exclusively fed to the longitudinal conveyor drums (2), which pass it on to the upper transverse conveyor drum (5), which finally ejects the clippings in the conveying flow (113).

In this way, almost all lying well on the ground and suck on the way on the drums (2) and (5) against the provided on the front of the loading wagon wall (53) and thus through the open step surface (58) feed the auger (116). Therefore, even with increased capacity extremely low loss can be worked.

Figure 16 includes a modification insofar as the lid (21) is replaced by a narrower lid (211) which covers substantially only the upper part of the rear of the storage caddy (1), while in the lower part an inclined strut plate (212) retracted is. Thus, once the circulation flow of the storage box (1) is improved, and on the other hand, its Torsionsstelfigkelt is increased.

One of the two transverse conveyor drums, preferably the lower can also be used to approach the end face (9) of the feedstock (10) to thereby hold a positioning for the initial cut, without the need for special funds bodarf. If you do not want the axial webs (85) no investment forces, flanges could be provided laterally of the drum shell, which can accommodate greater pressure forces, especially as they are close to storage.
