Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a device for dispensing or refilling at least one endless chain of debris removal chain bedding material which can be passed across the underside of the sleepers to remove debris such as crushed rock that has been cleaned and separated from earth and sand. Trackbed materials separated from each other, especially branch track sections,
The present invention relates to a mobile crushed stone cleaning machine that accommodates, dispenses and refills areas such as turnouts.

Known machines of this type are equipped with an endless chain for taking and conveying soiled or sandy roadbed material, such as crushed stone, to a sieving device, this chain having two chain guide longitudinals. You will be led to a side guideway that runs through the aisle and under the sleepers.

Sediment or sand is separated from the crushed stone in a sieving device, whereupon the sediment is deposited along a track by means of a belt conveyor system or loaded onto trolleys, and the cleaned crushed stone and, if appropriate, sand is refilled. is placed in the receiving area of the chain and thrown there.

Such types of track working machines or stone crushing and cleaning machines, whose chain guides were located inside the contour of the space surrounded by the track during work and movement, were very effective for straight track work. .

However, in areas with large track widths, for example in the area of long sleepers or branch track installations such as switches, rails, etc., such conventional machines cannot be used.

This is because the required width of crushed rock removal fundamentally exceeds the normal width of a straight track, and given the structural form of the crushed rock under such track sections, it is impossible to extract or transport it. .

However, machines are already known which are capable of mechanically processing crushed rock in track areas of such large width.

This machine has a sword-shaped scraping chain that runs parallel to the track surface and can travel on the underside of the track. Together with this scraping chain, crushed stones from the underside of the sleepers are scraped out and It is deposited near the side of the track or in front of the head of the sleeper.

However, since the traction chain is mounted in such a way that it projects freely laterally and the loads on it are too thick, it is not possible to guide the traction chain over a relatively large track area.

In particular, when removing crushed stone from below the turnout, it is first necessary to remove crushed stone from below one of the tracks, and then subsequently from the other, for example from below the branching track.

Moreover, when using this machine, a separate device is required for receiving the crushed rock deposited in the side area of the trackbed and lifting it to the sieving device.

Furthermore, Spanish Patent Application No. 104.471773 discloses a proposal for avoiding the installation of two separate devices for removing crushed stone from the roadbed in the turnout area and conveying it upwards.

This proposal concerns a movable cleaning machine with an endless chain, the removal width of which can be made larger or smaller by varying the angular position of the chain guide parts forming the crosspiece.

The length of the chain guide section, i.e. the crosspiece, remains unchanged, for example during work on track branches, regardless of the desired debris removal width at any given time, thus providing additional support for the chain. A guiding device is required.

Therefore, this machine is relatively complex in construction and requires a high power chain drive.

The purpose of this invention is to provide a system that can be used not only on straight tracks but also on turnouts, etc., and that changes in the rock removal width of the chain can be carried out simply and quickly without requiring any expense. To provide a machine of the type mentioned at the outset, capable of receiving, distributing and refilling trackbed material, and possibly also cleaning of trackbed material in such track installations as economically as possible. It is in.

This also leads to attempts to adjust machines currently in operation by modifying the necessary parts of such machines.

The present invention provides that the guide section of the endless chain extending transversely to the longitudinal direction of the track in order to selectively change the debris removal width consists of two parts that can be adjusted to each other in the longitudinal direction of the chain and that can be fixed. The distribution or refilling device for guiding the bed material is constructed so that it can be placed or moved over the entire debris removal width, and the chain and the distribution device are movable on the construction base or on the branch track. shall be connected to a suitable support and guide device.

According to the embodiment of the invention, the guiding length of the chain in the lower track region and the fluctuation clearance width, e.g. during the reception of crushed stone in the turnout region, are particularly well adapted to the distribution device. In this case, even if the length or pivoting movement of the chain guide is large, the resulting overturning moment or eccentric force can be supported by the support and guide device.

The drive force of the chain is adapted to the particular conditions by the variable length of the chain guide and possibly by the stone removal width itself; from this, the swingability of the chain can also be determined for each removal width. .

This makes it possible to greatly improve the workability, even in the case of receiving, conveying or cleaning crushed stone in the adverse track areas mentioned above, and thus to make possible an economical use of the machines mentioned above.

A further particular advantage is that such machines do not require much expense or large amounts of work when, after working in track areas such as switches or rails, they are subsequently intended to be used on normal straight track, etc. It can be applied without modification, and the combination of features of the invention provides for the first time a universal machine capable of performing mechanical work on all tracks, including track branches and straight tracks. become.

According to a further embodiment of the invention, a support and guide device is provided for supporting and varying the circumferential length of the guided endless stone removal chain in the polygonal body forming the chain or chain guide. Connected to the chain guide unloaded longitudinal path in a particularly bendable manner at the construction base or on the branch track,
The distribution device is composed of at least one belt conveyor device or shooter device that can be changed to a desired conveyance width.

This allows the chain guide to be turned to the no-load side or to the side when turning, such as when a larger debris removal width is required.
This allows precise upward guidance of the part of the chain extending transversely to the longitudinal direction of the track and problem-free refilling over the desired filling width.

A movable belt conveyor device or chute device makes it possible to evenly distribute the crushed rock coming from the sieving device over the entire operation even when the working capacity of the machine is large.

Further features of the invention include the following: In order to maximize the debris removal width, a hydraulic cylinder-piston drive, known per se, with a chain guide which can be swiveled up and down and left and right, for example, has two The driving mechanism of the chain guide unloaded longitudinal guide path for the swivel area for assembly is formed by parallel running rails of at least eight to nine chain guides in the chain guide transverse path constituted by the lower belt of this chain. Formed from cross passage pieces.

As a result, for example, the crushing of stones under a switch or tip during operation is such that there are so many locations between the branched tracks that each track itself has to be further worked on, for example by known machines. can be accommodated over a very wide range ζζ.

If a hydraulic drive is provided for selectively adjusting, moving, and especially tensioning the chain guide assembly or the chain, disassembling and assembling the chain guide transverse passage pieces or extending or shortening the chain is very simple. It is advantageous if this is possible, in which case the assembly transverse passage piece is provided towards the chain guide unloaded longitudinal passage.

As a result, when increasing the debris removal width of the chain guide transverse channel, it can be extended in the direction of the longitudinal channel, thereby reducing eccentric forces or overturning moments occurring in the machine.

Further, in that case, a mechanical holding device is not necessary because the hydraulic drive device can perform the holding, and the large force generated in the chain guide can be transferred to the hydraulic drive device without any problem.

In machines that are equipped with a sieving device for cleaning or separating the bed material next to the chain, the exit of the sieving device is used to selectively distribute and feed the bed material in accordance with the desired removal or distribution width. A guiding device is provided.

As a result, the cleaned crushed stone that is guided to the individual distribution devices or belt conveyor devices is already coarsely regulated, so that belt conveyor devices installed, for example in chain-guided unloaded longitudinal paths or branch tracks, are Substantially more crushed stone is introduced than for other belt conveyor systems.

In that case, it is advantageous if guide devices are provided at the bottom of the sieving device at three locations and vibrating ramps running obliquely to the longitudinal axis of the tracks are formed.

In order to transfer the cleaned crushed stone and sand from the sieving device to the belt conveyor device without any problems, in an embodiment of the invention the vibrating inclined plate is located at the maximum swivel position transverse to the machine longitudinal direction of the belt conveyor. Advantageously, it extends substantially perpendicular to the device.

In order to redistribute and guide the crushed stone removed from the region of the branching track into this region, a sieve base is installed in each of the three sieve bases, which are provided one above the other in the region facing the swing path ramp, in particular at the sieve base. A stone crushing device is provided which can be moved or swiveled around an axis running at right angles by means of a drive.

Finally, it is a further feature of the above-mentioned type of machine according to the invention that, for the separation or distribution of the crushed stone and sand mixture, the first outlet of the chute connected to the sieve bottom is arranged above the belt conveyor half. Furthermore, it is advantageous if the second outlet of the second chute, which is also connected to a further sieve bottom with a cover, opens onto the second half of the belt conveyor formed by the intermediate material.

Such a procedure is very simple and makes it possible to separate or distribute trackbed material in large quantities and to work with relatively high efficiency in difficult-to-handle track areas or track equipment.

The invention will now be explained in detail on the basis of an illustrated embodiment, that is, an embodiment of a crushed stone cleaning machine.

The movable crushed stone cleaning machine shown in Figure 1 is for receiving, distributing and refilling trackbed material and can be used not only in turnout areas but also on main lines.
hotterbett-reinigs-maschi
ne), which also cleans the crushed stone at the same time.

This machine includes an undercarriage frame 1, which is supported and guided on the rails of a track 3 via a bogie car 2.

An endless chain 4 is provided for removing crushed stone from the underside of the sleepers of the track 3, which chain is led into hollow chain guide longitudinal channels 5, also 6 and chain guide transverse channels 7.

The crushed stone covered with earth and sand, which is removed by the chain, is brushed off onto a sieving device 9 in the area of the chain 1 drive 8 .

The sieving device has three sieve nets 10 arranged one above the other, and these nets separate crushed stone from earth and sand and clean it.

The crushed stone is transferred to a refilling device (wieder) via a distribution device 11.
einbringeinrichtung)l 2.

The earth and sand separated from the crushed stones fall onto a conveyor device 13, and are swept away along a track by this conveyor device or are crushed by a cart.

As can be seen from the plan view in Figure 2, the chain guide horizontal passage 7
consists of a number of chain-guided transverse passage pieces 14 in which crushed rock can be simultaneously removed under the track 3 and the branch track 15 and led to a screening device 9.

For moving the hollow chain guide longitudinal channel 5 from side to side and up and down, cylinder piston devices 16 and 17 are provided, and for the chain guide longitudinal channel 6 cylinder piston devices 18 and 19 are likewise provided. ing.

The cylinder-piston devices 16 and 18 are arranged so that, in particular during the assembly of the chain guide transverse passage 14, the two chain guide longitudinal passages 5.6 are separated from each other so as to be transverse to the longitudinal direction of the track. After assembly of the piece 14, it is used to move the longitudinal chain guide passage towards the transverse chain guide passage.

The chain guide transverse channel piece 14 is then sometimes moved towards the chain guide longitudinal channel 5, so that the chain guide transverse channel 7, viewed from the working direction, is moved in such a way that it is possible to remove the track material on the lower side of the branch track. Can be lengthened on the right side.

The chain guide horizontal passage piece is provided with guide portions provided at both ends thereof so as to correspond to each other and fit into each other,
They can be connected in any suitable manner, for example with specially formed clamping devices such as wedges.

In this case, the wedge is connected to the connected chain guide transverse passage piece 14.
It is formed so that it can be held and bent.

The connection of the individual guideway pieces 14 makes it possible to insert this part in the working direction, so that assembly can be carried out without problems even in very tight space conditions.

Chain guide horizontal passage pieces on both sides of the chain guide vertical passage 5,
6, the ends of these longitudinal chain guide passages on the track bed side are provided with appropriate guides, similar to the cross chain guide pieces 14.

After inserting the chain guide horizontal passage piece 14, tension it.
Alternatively, the chain guide vertical passage 5 is divided into two parts in order to loosen and tighten the guide passage piece in order to insert the next guide passage piece, and the two parts are moved in the longitudinal direction of the chain by a drive device 20. It is now possible to do so.

Since the turning radius of the chain is large, it is necessary to slide or roll on the construction base 21 in order to guide the vertical chain guide passage 5 according to the height, especially when storing trackbed materials in a track system with wide branches. A movable support and guide device 22 is attached to the guide path 5 so as to be bendable.

As is clear from FIG. 2, the refilling device 12 constituted by the conveyor device 23 can be swiveled laterally by an appropriate amount as necessary to bring the track area of the branch track 15 into the working range without any problems. It is now possible to do so.

In order to absorb the relatively large eccentric forces that occur when pivoting the conveyor system, the refilling device 12 is likewise supported by a support and guide device 24.

The support and guide device 24 can then be supported on the rails of the branch track 15 or, like the support and guide device 22, on the construction base.

As shown in the plan view of FIG. 2, the conveyor device 23 can be pivoted by a piston-cylinder drive 25 from the position shown in solid lines to the position shown in broken lines.

Two belt conveyor systems are provided at the outlet of the distribution device 11, but have been omitted in FIG. 2 for clarity.

In order to control and monitor the machine and in particular the upper and side parts of the chain 4 and belt conveyor device 23,26 as easily as possible, the cylinder piston 1 drives 16 to 19 and the support guide devices 22 and 24 are equipped with a control or pressure medium. It is connected via a conduit to an operation panel or a shared control and monitoring device 27 in the machine operator's room.

FIG. 3, which shows a front view of the machine along the working direction, shows the orientation of the individual cylinder-piston drives 16 to 19, but in FIG. Sieving equipment is not shown.

FIG. 4 shows, for example, when a mixture of crushed stone and sand is taken out together with the chain 4, and the sand is separated from the crushed stones in a sieve to form a sand layer between the construction base and the road bed.
of the construction of the belt conveyor device 23 to ensure that sand and crushed stone are filled separately and continuously along the working direction, for example as described in DE 2,331,914; The main parts are shown enlarged.

The end of the belt conveyor device 23 is in this case equipped with a deflection device 28 which limits the discharge distance of the crushed stone, seen from the working direction, so that the crushed stone does not fall into the sand layer after being filled with sand. be thrown onto the

Furthermore, it can be seen from this figure that the support and guide device 29 for the chain guide longitudinal path is separated from the support and guide device 22 shown in FIGS. It can be seen that is shown enlarged compared to FIG. 1.2.

The support guide device for the chain guide device is a sled-shaped support 3
0, this support is connected via a guide rod and by means of a cylinder-piston arrangement 31 to a chain guide longitudinal channel 5.
It can be bent upward at the top.

A vibration device is further provided on the support body 30,
As a result, the filled sand is flattened or shaped, and the sand layer is compacted.

At the same time, the chain guide longitudinal channel 5 and therefore the chain 4 are also excited, which may facilitate loosening of the lower trackbed of the track 3 and the branch track 15, resulting in a relatively large debris removal width. It turns out that the drive output of the small chain 4 will suffice.

Belt conveyor 2 shown schematically in FIGS. 1 and 2
The support and guide device 24 for the No. 3 vehicle consists of a guide track 32 supported on the branch track 15 via a wheel with a ring.

Two adjustment drives 34 are movably mounted on this guide track 32 with a double flange roller 33 in between, and the other end of this drive is connected to the belt conveyor device 2.
It is guided by rollers in a longitudinal guiding device 3.

The height of the belt conveyor device 23 is adjusted by means of this adjustment drive device 34.

As shown in FIG. 2, in order for the undercarriage frame 1 to absorb the large eccentric force or overturning component that occurs when the belt conveyor device 23 turns outward, the guide track 32 is provided at its end region on the track 3 side. It is connected to the chassis frame 1 of the machine via a support cylinder 36.

Due to the double flange rollers 33 and the longitudinal guide device 35, the rotation of the belt conveyor device 23 is not hindered.

However, it is also possible to omit the guide track 32 and to provide a correspondingly constructed support device (FIG. 1) or to connect it with a support and guide device.

As shown in FIG. 4, an intermediate plate 38 is provided to assist in separating and filling the crushed stone and sand, so that the sand and crushed stone are transported through the sieve at the same time on the same belt conveyor device, but separated from each other. carried to the dropping position.

FIGS. 5 and 6 show the structure of the sieving device 9 and the distributing device 11 disposed at the next stage.

The sieving device 9 passes through the chassis frame 1 on the coil springs and cross members.
It is mounted elastically on top, pivots the machine center around an axis running in the longitudinal direction of the machine by means of a swiveling and drive device, and generates vibrations, for example by means of a counterweight driven by a hydraulic motor.

By means of the swivel drive, it is possible to adjust the sieving device 9 always horizontally, especially in medium-height curves, or even always parallel to the undercarriage.

The sieving device 9 is used for refilling roadbed crushed stones or sand.
and belt conveyor device 2 on both sides for transporting earth and sand
3 to 26 and behind the belt conveyor device 13 - refilling device 12 -.

The belt conveyor devices 23 and 26 are connected to an intermediate plate 38 (fourth
(Figure).

The distribution device 11 surrounds a roughened tube 39 attached to the uppermost sieve base 10 and a rock crushing control device 40 .

The rock crushing control device 40 is connected to a tilting device 41, for example a hydraulic cylinder piston device.

Two shooters are provided on both sides of the rough tube 39, separated from each other by a guide device 42, and their outlets are connected to one of the conveyor belt halves separated from each other by an intermediate plate (FIG. 5). They are configured to be sent to each other.

By means of a displacement drive 43, the vertical part 4 of the introducing device 42
4 can be tilted obliquely with respect to the longitudinal axis of the machine, so that the amount of bed material fed into each belt half can be adjusted, this being shown in broken lines.

Between the three sieve bases 10 and the chute, which is separated by the introduction device 42, there is a triangular thin plate extending the sieve base 10, extending obliquely to the longitudinal axis or plane of the track and covered with rubber. A vibrating floor plate 45 is provided.

As is clear from the right half of FIG. Extending at right angles to the longitudinal axis of the device.

In the exit area of the chute separated by the introduction device 42, another introduction device 47 is arranged, so that the belt conveyor device 23,26 does not only run parallel to the longitudinal direction of the machine; Even in its maximum swivel position, it can be processed, for example, with separated track material on both belt conveyor halves without any problems.

Two further rock crushing controls 48 are mounted below the sieve base 10 and are connected to a swivel 1 drive 49 common to both.

The operation of the illustrative embodiment of the loading, dispensing, refilling and simultaneous cleaning of crushed rock in the turnout area of the trackbed cleaning machine - FIGS. 1 and 2 - will be described below.

As the machine approaches the switch from the smaller side of the switch (Figure 2), the length of the sleepers increases and the chain guide lateral passage 7 has a reduced working capacity to handle the increasing debris removal width. It has to be big.

In order to extend the chain guide transverse passage 7, the chain guide longitudinal passage 5 is removed from the chain guide transverse passage piece 50 or from the last inserted chain guide transverse passage piece 14;
It is pivoted to the right by the cylinder-piston arrangement of FIGS. 2-3.

The chain guide transverse passage piece 14 is then guided in the working direction and from behind along the chain 4 towards you (so that the chain 4 must not be separated in that area).
Then, it is connected to the chain guide horizontal passage piece 50 or the chain guide vertical passage piece 5.

Simultaneously with the assembly of the chain guide transverse channel piece 14, the length of the chain 4 between the two chain guide longitudinal channels 5 and 6 is extended by the chain section of the chain guide longitudinal channel 5 in the region of the drive device 20.

The length of the chain guide transverse channel 7 is gradually extended by the tension action until the distance between the opposite ends of the sleepers of the branching track is 50 to 70 cm.

Each trajectory is then processed separately from then on.

This maximum debris removal width of 6 to 7 m is fitted with approximately 8 to 9 chain guide transverse passage pieces 14, which provide a very flexible adaptation at the given location from time to time. The chain guide horizontal passage piece 14 is not too heavy.
Also, since it is not too heavy, it becomes very easy to handle.

The crushed rock lifted by the chains is dumped onto a screening device in the area of the chain drive 8.

During the cleaning of crushed stone from the road bed, the crushed stone is separated from dirt or coarse particles on the vibrating sieve base 10.

The earth and sand fall through the sieve onto the belt conveyor device 13 and are thrown out, for example, in the vicinity of the track.

In addition, since coarse grains must be separated, two deflection plates are attached to the top sieve bottom 10.
As a result, coarse grains are collected in the coarse grain chamber 39.

On the other hand, in order to guide the crushed stones cleaned from the lower sieve bottoms on both sides in sufficient quantity to the belt conveyor device 23 for the branch track 15 according to the width of the crushed stones removed from time to time, and as a result, in this branch part A rock crushing control device 48 is provided in both of these groove bottoms 10 so that standard sections can be produced according to the working process.

These devices are attached to the assembled chain guide horizontal passage piece 1.
4 can be swiveled counterclockwise (B) (Fig. 6) depending on the number of stones, so that in the maximum case approximately 2/3 of the total amount of crushed stone cleaned is conveyed by the belt conveyor device 23 or Depending on the situation, it may lead to 26.

Furthermore, a further control of the amount of crushed stone in the distribution device 11 can be carried out by means of the pivotable part 44 together with the displacement drive 43.

In order to distribute the crushed stone in the area of branching tracks, a piston -
A belt conveyor device 23, which can be swiveled by a cylinder drive 25, works.

In order to enable the necessary pivoting of this, a floor plate 45 is provided, so that the track of the chute and the amount of crushed stone can be adapted in the required pivoting position.

Moreover, the rotation of the belt conveyor device 23 in the direction transverse to the longitudinal direction of the track is the length of the chain guide transverse path? Even at the maximum removal width of the side of the trackbed, for example, the crushed stone can be guided sufficiently to be held in the pivoting position for a short period of time.

As can be seen from the above, the chain guide vertical passage 5
Both the belt conveyor device 23 protrude outward to a very large extent when the crushed stone removal width is at its maximum.

Even if the weight of the bed cleaning machine is small, supporting or guiding devices 22, 24.2 are provided in order to obtain sufficient installation stability of the machine and an arrangement with good workability according to the overturning moment that occurs.
9 is provided.

In addition, in particular by means of the supporting guide device 22.29 of the chain guideway, the ascending and likewise descending guidance of the chain 4 is carried out well, so that damage to the construction base is avoided and the durability of the track cleaning and its quality are improved. is further enhanced.

The cleaned crushed stone is conveyed in addition to belt conveyor devices 23 and 26 which move pendulum-like transversely to the longitudinal direction of the track, and which are installed in the rear wall of the chute forming the rear wall of the sieve and which move perpendicularly to the track plane. Get two sliding lids (schje
ber) and then immediately into the orbital region.

Each chute separated by the guide device 42 is fitted with such a sliding lid, which is moved upwards by a special drive (shown in broken lines in the right-hand part of FIG. 5).

It is further stated that a switch can be operated with the above-mentioned machine not only from its narrow side, but also from its opposite side, and therefore also from its wide side.

Thereby, it is also possible to take out and store the track bed material under the tip or switch.

In these various working configurations, especially those in the grass area, maximum debris removal widths can generally be operated if switch drive or location conditions permit.

However, it is possible to remove or install one or several chain guide transverse passage pieces 14 at the same time.

The necessary lengthening of the chain 4 is then achieved by inserting the chain or by constructing a tensioning device with an appropriately large tensioning length.

The tension length or adjustment length of the drive device 20 is in this case:
It is long enough that eight to nine chain guide transverse passage pieces 14 can be assembled without assembling additional chain sections.

The above-mentioned machine is not only used to clean roadbed crushed stones, but also to clean the construction base 2.
It is also used to form a sand layer between the grains and the grain bed, in which case the deflection plate 51 is removed from the upper sieve bottom 10 and the opening of the coarse grain chamber 39 is closed by the lid plate 52.

Further, a small mesh sieve is attached to the uppermost sieve bottom 10, and a rubber mat shown in dashed lines (FIG. 5) is attached to the middle sieve bottom.

This leaves crushed stone at the bottom of the top sieve and sand at the bottom of the middle sieve.

By providing an auxiliary introduction plate 54 in the region of the intermediate sieve bottom 10, crushed rock from the upper sieve bottom falls into one of the chutes divided by the guide device 42;
What is achieved is that the sand falls on the other side (see dashed arrow in FIG. 5).

As a result, sand or crushed stone is fed into each of the halves of the belt conveyor devices 23 and 26 separated by the intermediate plate 38.

In order to fill the track bed cross-section with cleaned crushed stone without problems, it is advantageous to fill the gaps between the sleepers using sliding lids in the rear wall of the sieve, which are provided on both noyers facing each other at a distance.

Sand and crushed stone, which are conveyed simultaneously but separately from each other by the belt conveyor devices 23 to 26, are transferred to a diverting device 28.
(FIG. 4), it is separated and brought into the area of the support and guide device 29.

Owing to the large swirling properties of the belt conveyor devices 23 to 26, sand is also brought into the region below the branch track 15 in the required quantity.

In order to regulate the amount of crushed stone or sand introduced into the individual belt conveyor devices, crushed rock control devices 40 and 48 are used in this case.

The sieve can be tilted in the direction of the branch track 15 by means of a tilting device so that the distribution of the supply of cleaned bed crushed stone or both to the belt conveyor device 23,26 can be controlled already in the area of the sieve device 9.

Furthermore, the chain guide longitudinal channel 6 is provided with a longitudinally movable sliding lid in its end region facing the chain 1 drive 8 .

This sliding lid is moved towards the chain guide transverse channel 7, so that all the track material received can be guided to the belt conveyor device 13.

When moving in the opposite direction, the track material is carried along longer by the chain 4 and an acceleration transverse to the longitudinal direction of the machine occurs.

This crushing movement is supported by an auxiliary guide plate extending obliquely to the longitudinal axis of the machine and pivoting from a height (Fig. 1), so that the bed material is already directed in greater quantities into the branching track of the sieving device. I am thrown out by law.

In some cases, if the machine travels along a branch track rather than a main track when the switch is activated, for example,
It is necessary to provide supporting and guiding devices 22 to 29 of the chain guide longitudinal channel 6 and supporting and guiding devices 24 of the belt conveyor device 26.

However, since in this case no crushed stone material is transported and the overturning moment exerted on the machine is kept small, it is advantageous to extend the chain guide transverse channel 7 in the direction of the longitudinal chain guide channel.

Finally, it should be noted that the structure of the machine or chute, the control device, or the belt conveyor device and the drive device thereof shown in the embodiments can be modified in various ways.

It is also possible to use a rope type operating device, a threaded rod type device, etc. instead of the hydraulic cylinder piston device used in preference.
