Attachment for shovel loader

The invention relates to an attachment for a shovel loader, which consists of a loader vehicle and a loader vehicle that can be lifted thereon and & ■

tiltable loading shovel exist. H

In this context, a shovel loader is to be understood as any vehicle to which a liftable and tiltable loading shovel is either permanently attached or can be exchangeably attached. The loading shovels can, for example, be designed as full-walled sheet metal buckets or be completely or partially perforated, for example in the manner of a sieve grate, so that fine-grained material can fall through.

Loader vehicles of the type mentioned are, for example, tractors, wheel bearings and crawler loaders. . j§ /

The attachment according to the invention is primarily intended to Picking up stones from agricultural fields. In the case of stony soils, presents itself before, during or after the Ordering the fields the task of picking up the stones lying on the field and transporting them away. By hand or by hand Rakes pulled by a tractor can only be used to read relatively small stones; bigger stones had to be used up to now be picked up individually by laborious manual labor and brought to a waiting transport vehicle. Only for a lot Large stones, it was justifiable in terms of workload and because of the weight of the stones it was also necessary to use them a lifting device, for example by means of the loading shovel of a loading vehicle. If possible, the stone was Move under it individually with the loading shovel or by hand into the

Rolled the loading shovel lowered on the sod. This process is very laborious and only proportionate for individuals large stones still appropriate.

It is true that stone reading machines are known which pick up stones lying in a row and place them on a conveyor belt Load the transport vehicle. These machines work continuously and can be used especially in newly cleared fields if the stones are numerous, but are not too big. These stone harvesting machines, however, are for those that occur every year when spring cultivation occurs Stones not suitable because, on the one hand, the mechanical effort is very high, but on the other hand, by hand or with Tow rake a pre-arrangement of the stones in long rows is necessary.

The object of the invention is therefore to create an attachment of the type mentioned at the outset which enables it to be used conventional loader vehicles, for example agricultural ones Tractors with loading shovels to fully mechanize the picking up of stones of very different sizes, to avoid laborious manual labor. This is a medium-sized task, especially with the stones that occur frequently Size for which a single loading process with conventional loader vehicles is too expensive, can be removed by hand but is very troublesome.

According to the invention, this object is achieved by an attachment initially mentioned type solved, which is characterized in that a parallel to the front edge of the loading shovel extending rake with downward rake prongs is rigidly attached to at least one rake that the computer carrier is guided on at least one swivel arm transversely to the longitudinal direction of the computer and by means of a computer drive

is movable and that the swivel arm by means of a swivel arm drive is pivotable about a pivot axis lying parallel to the longitudinal direction of the rake.

This with little additional construction effort on each shovel loader Attachable attachment allows stones of different sizes to be moved quickly and without manual work into the loading shovel promote and transport away with this. It is sufficient to place the loading shovel on the ground in front of the stone or stones, to rake the stone or stones into the loading shovel and then move on to the next stone. When the loading shovel is completely or almost full, it is lifted and placed in a waiting transport vehicle or on a pile of stones tilted.

The attachment can be used with its rake at the same time as a gripper that interacts with the loading shovel Pick up straw, hay, wood or other material with the loading shovel and hold it with the rake during transport.

According to a preferred embodiment it is provided that the data carrier is guided telescopically on the swivel arm. The swivel arm can be swiveled at the top of the loading shovel be stored. The swivel drive can have a piston-cylinder unit actuated by pressure medium, which is on the one hand on the loading shovel and on the other hand is articulated on a lever arm connected to the pivot arm. In this embodiment No mechanical fastenings are required for the attachment on the shovel itself, since the loading shovel is all mechanical moving parts. These can be dismantled together with the loading shovel and exchanged for another attachment will. Instead, it is also possible to leave the loading shovel on the shovel loader uru? the remaining parts of the attachment to dismantle.

The invention is explained below on the basis of exemplary embodiments explained in more detail, which are shown in the drawing.

The attachment shown in Figures 1 and 2 and shown in Figure 6 in the attached state has a conventional, Loading shovel 1, which is open at the front or at the top, has a rake 2 which extends parallel to the front edge 3 of the loading shovel 1. The rake 2 has several, downwardly directed rake prongs 4, which are rigid but interchangeable on a transverse Rake bars 5 are attached.

Together with two data carriers 6 which extend transversely to the longitudinal direction of the calculation and which, in the embodiment according to the Figures 1, 2 and 4 are each formed by a T-profile, the rake 5 forms a movable component with the rake prongs 4. The racks 6 are telescopic on two Swivel arms 7 guided in a longitudinally movable manner, which are supported by a transverse

carrier 8 are rigidly connected to each other. The pivot arms or their cross members 8 are parallel at joints 9 by one The pivot axis, which lies in the longitudinal direction of the calculation, is pivotably mounted on the upper side of the loading shovel 1. 5

In each case a hydraulic piston-cylinder unit 10 attached to the swivel arm 7, the piston rod of which is on the rack 6 engages, forms a rake drive to move the rake 2 back and forth in the longitudinal direction of the pivot arms 7. 10

A hydraulic piston-cylinder unit 11, on the one hand on the loading shovel 1 and by means of its piston rod other | is hinged on the cross member 8, forms a swivel arm | drive to the pivot arms 7 in the indicated in Figure 6 '

The load for driving the piston-cylinder units 10 and 11 | required hydraulic system is not shown in the drawing. It goes without saying that this is the hydraulic system of the shovel loader 12 (Figure 6) can be used, which is already present to lift the loading shovel 1 and to tilt. One of the hydraulic cylinders used for this can be seen in FIG.

A modified embodiment is shown in Figures 3 and in partial sections. The two parallel racks 6 * consist of a square tube that is in one somewhat larger, telescopic square tube forming the swivel arm 7 ' is led. For this purpose, between the two square tubes δ 'and 7' Führerie list 14 from a good Slidable material, for example * bronze / on the ends of the square tubes 6 'and 7 · attached i & a. The Kolbeh cylinder unit 10 'is in this embodiment within the Square tubes 6 'or 7'.

From Figure 4 it can be seen that in contrast to this, in the embodiment shown there, the swivel arm 7 consists of two angular profiles arranged at a distance from one another,
between the upright angle legs of the web of the
is guided in cross-section of T-shaped data carrier 6.

In Figure 6, the function of the attachment as a stone rake is shown in several positions. The bucket 1 will lowered to the ground in front of a stone 15 to be picked up,

while the swivel arms 7 by means of the swivel arm drive 11, the rake 2 in the raised and extended position
keep. From this position, the rake 2 is by means of
Swivel arm drive 11 is lowered until it engages behind the stone 15. In this position, which is shown in Figure 6 with dash-dot

-T5 th lines is indicated, the rake 2 is drawn in by means of the rake drive 10, the stone 15 being conveyed into the loading shovel 1. The shovel loader 12 is then moved to the next stone, which is picked up in a corresponding manner until the filled loading shovel 1 is emptied onto a transport vehicle or onto a pile of stones
will.

The rake 2 can also be used as a gripper to remove bales of material, for example, hay or straw, or loose material lying on the ground, such as wood, and on the Hold loading shovel 1.

Depending on the type of material to be picked up, modified embodiments of the rake prongs 4 can also be used. In Figure 2 it is indicated with dash-dotted lines that the rake prongs can be designed as protruding prongs 4 'of a blade plate 2 attached to the rake bar 2 ⁽ *
