If äUöh can find the Weighing ^one question for many things änder'e application as zurrt example of size container with f'aüettenboden or bolts of cloth, etc., it is referred to here in its typical application, that is for the Lädenj ilen transport and Unloading of gYosseh cylindrical hay spring bales of straw, also called "RoILballs", described and. ν CiargestelIt,

The transport of these bales from the field in which they are formed to the storage area poses a significant problem since these bales are rather large and heavy and not with the usual known trolleys or means for collecting cases, which are lighter and of prismatic shape can be included >

Today more than one car is known to solve this problem, the one specially designed for collecting and transporting roll bales was developed.

J These trolleys are based on the general concept of a support bed

Provide appropriate walls on which the bales are loaded from above, with the help of forks which are located on the side or rear of the wagon, and which grip the bales lying on the floor from below or from the side, lift and lay on the support bed. In addition, continuous transport chains are necessary, whether fts to the bales to be directed and distribute do along the Stützbeft, whether to dump back to the bales.

Although these wagons perform for the purpose for which they are intended meet drawn, however, the present invention offers a new type of V / agent that highlights the following Has advantages:

- A considerably lighter structure and lower cost for the same performance;

- a smaller number of operating equipment such as hydraulic winches, Translations, transport chains and related parts;

- great agility and speed in operation it during loading and unloading, especially of bales;

- the ability to take the car apart and put it back together easily and quickly, making it a more advantageous one Storage and more economical transport given is.

These and still other advantages are achieved by the subject carriage which is characterized in that it includes the following; - A receiving frame in the form of a tunnel, which describes an empty space and is able to receive one or more bales lined up one behind the other, v / obei said frame has a longitudinal opening on the lower side, which runs over the entire length of the tunnel and its The width is less than the diameter (or the width) of each balleris, and wider than the surface of the 8aIlon on the Bödönj: ^β a halferahwen, which is made with rollers or other means that make the movement more efficient.

Lent, and connected to a towing vehicle for the car is and is used to hold the receiving frame, said support frame on the outside of the receiving area for the Bale runs along and not under said longitudinal opening; - mechanical lifting means held by the support frame and which in turn support the receiving frame by making it in relation to the support frame in two different ways Hold Positions: A lower position for loading and unloading the bales with the lower and open sides of the The receiving frame rests on the floor or is only a short distance away from it, and an upper position for transport the bale raised in relation to the previous one at that any bales in the pick-up area are lifted from the ground.

Other features and advantages of the present invention better go from the detailed description below a preferred, but not exclusive, form of realization which is presented purely by way of example and not by way of limitation with the help of the accompanying drawings in which |

With reference to the above figures, 1 denotes the car in question, which is connected via a front-mounted control 2 to a towing vehicle for the car, specifically to a tractor 3. The car 1 contains a receiving frame 4 in the form of a tunnel which describes a void and the longitudinal axis 11 of which is parallel to the longitudinal axis of the carriage; this area is able to accommodate a number of bales (in the example shown in the figures there are four bales that can be accommodated in this area) which are lined up one behind the other. The lower part of the frame 4 has a longitudinal opening 7 which runs the entire length of the tunnel and the width of which is smaller than the diameter of each bale, but larger than the width of the contact surface of the bale on the ground. The carriage 1 also contains a support frame 8, which is provided with rollers 5 or other means for its movement and is connected to the tractor 3. The receiving frame 4 is attached to this support frame 8 on the underside. The mentioned frame 8 runs along the outside of the sewing area for the ßalisn along and sews below the opening 1,

The carriage 1 also contains mechanical lifting means 9 that are held by the support frame 8 and in turn the receiving frame 4 by holding it in two different positions in relation to the frame 8: A lower position A for loading and unloading the bales, in which the lower and open side of the frame 4 rests on the ground or only little protrudes from this, in such a way that the cylindrical

, \ Bales (roll bales) that may be present in the receiving area are to rest on the floor, as well as an upper position B for the transport of the bale, which is raised in relation to the previous one and which may be in the receiving area existing bales are lifted from the ground. The receiving frame 4 contains a number of large forks 41, those bent with their ends 41 * downwards and evenly They are spaced on vertical planes, and one behind the other, so that they form an ideal tunnel. At the lower and open ends 4P of said forks' are fixed two elongated guide and support elements 6 (long

Rods), while at the upper end of said sabers the said lifting means 9 are attached. The two Guide and support elements 6 run horizontally and are parallel attached to the axis 11 of the tunnel on the sides of the opening 7; these elements 6 constitute the principal or unified ones Elements on which the balls of Io rest. Said elements 6 protrude forward over a certain one StüGk in relation to the first fork 41a above and beyond

And 2-Wäf so that this' ball fi IfI comes about right from the front ends 61 of the elements 6 in "guide", and that their own axis and the longitudinal axis 11 of the receiving area are on the same ideal vertical plane, Ah At this point, frame 4 is brought into lower position A! In this position, the elements 6 are located at a short distance from the floor, or at such a distance from the floor that they can push the ball ICP lintly! It should also be noted that in this position A, the longitudinal axis 11 of the flaking area approximately coincides with the axis of the bale 1O ¹ "(this position can be seen in FIG pushed forward, the elements 6 can slide under the bale to the side of the bearing surface of the bale hoof on the ground This advance takes place in the direction of the axis 11 over a distance which corresponds to the length of the bale and stops as soon as the bale 10 * has occupied the first section Cj of the receiving area. The frame 4 is now in the upper position B lifted and the bale 10 * is also lifted from the ground and lies on the elements 6. In this way, the receiving phase of the first bale 10 * is completed one bale 10 " ^v (position shown in Fig. 6A) in the same way as described above for the first bale 10 *,

and the frame 4 is consequently brought back into the lower position A (position shown in Fig. 6B). Here the bale 10 * lies again on the ground and is in contact with the bale IU ¹ "* and hits with the ei = (that axis on that of the bale \ 0 ^<y or almost, then the carriage 1, always in the direction of the axis 11, is advanced for a distance that corresponds to the length of the bale (in Fig. 6C position shown), In this phase it therefore results - that the frame 4 moves around the bales 1θ ^ν and 10 * "■, which are lined up on the floor and are then inside the receiving area, as in positions C2 And C].

Then the frame is raised to the upper position B and the bales 10 ^ and 10 ^vv are also lifted from the ground and lie on the elements 6 (position shown in Fig. 6D. In this way, the pick-up phase of the bale 10 "is completed ,

Proceeding in the manner described above, all bales are loaded into the receiving area that it can hold (into the The recording area can accommodate up to four bales of images, but of course the number can also be larger or smaller • a).

The bale unloading phase is very simple: it is sufficient to bring the frame 4 to the lower position A so that the up The bales in the cart rest on the ground, and then push the cart forward. The Balts are at that

It should be noted that when the frame 4 is in position B, the balls present in the receiving area on the upper side against the levers 91 and against the rods 83 and 84 (see Fig. 5) in order to raise the bales to hold in this way and to damage leading to vibrations or displacements of the charge inside the receiving area to avoid,

It is also provided that the elements 6 in relation to Axis 11 can be mounted in several positions, or their position can be changed in the radial direction, what serves to reduce the distance between them in order to adapt the cart to the dimensions (diameter) of the bales to be loaded. It is also provided that the frame 82 is bolted on the long sides 85, that the elements 6 on the ends 4P of the forks 41 are bolted, and that the steering 2 is easily removable, as are the various bolts of the lever 91, namely to the Zv / corner, the space required by the car for storage or transport. In this way, the structure of the car is easy to disassemble and put it back together again.

Obviously, numerous changes can be made to the invention to be more practical Kind of attached in the details, such as, for example, the shape of the forks 41 can be different from the one shown, as far as they are so that they all grip around the balls from the outside and dl © elements 6 can carry, for example the
