Method and device for handling bales of straw or similar straw material

The invention relates to handling bales of straw or similar straw material.

Straw or hay is usually left in the field for a short time after the harvest. A baler is then used to pick up the straw material and form it into balls that are generally 35 by 45 cm in cross-section and between 90 and 45 cm in length 110 what have. The farmer then has the problem of organizing the removal of the bales from the field or directly from the baler to a suitable storage area or in a barn.

309833/0449

Bringing the bales one by one onto a transport vehicle by manual labor is a heavy and exhausted job Time and manpower and is therefore inadequate in the green. A better method is to bale the balls manually in groups, tying the groups into bale blocks and these blocks with a tractor front loader to handle or the like. There is considerable manual labor. but still required to bring the bales in groups, since each bale can still be handled and moved essentially individually.

In accordance with the invention there is provided a method of handling bales comprising inserting a bale in a predetermined orientation upwards into a block formation area, inserting subsequent bales, each with at least one previously inserted bale for Forming a column of balls moving upwards, the side Moving the column and forming at least one another such column of bales adjacent the preceding column, thereby forming a bale block.

In another aspect the invention provides a bale handling machine having means for inserting a bale upwardly into the predetermined orientation a blocking area, for subsequent insertion the bale for engaging and moving at least one previously inserted bale to form a bale column, and means for laterally moving such a column, thereby creating successive columns, adjacent at the first row, can be formed and a ball block is formed.

The ball block is preferably tied when a predetermined Number of pillars are formed and then will

309833 / ÖU9v ■ :. -: - -

from. push the machine out.

The block preferably comprises five columns of four each Bales to form a block of twenty bales.

The invention provides a method and a device for handling bales of straw material. The bales are aligned by the device and then successively moved upwards, each bale the previous one moved to form a column of four bales. The column is then moved backwards and another four Rows are formed. The moving bales cause tying material to unwind from a roll. Of the complete block of twenty bales is then tied to its perimeter and used by the device as one for that Ejected handling by a normal tractor front loader block of comfortable size and weight.

The invention is exemplified below on the basis the drawing described; in this shows:

Pig. 1 the device according to the invention schematically in longitudinal section; and

Pig. 2 shows a section along line 2-2 in Pig. 1.

The drawing shows a bale handling machine with a frame 10 which is mounted at the rear on ground wheels 11 and is equipped at the end with a pull rod (not shown). The wheels are preferably adjustable in a caster wheel state and a fixed wheel state by locking pins. The first state is used when the machine with a fixed drawbar directly connects to a baler and this in turn

309833/0449

is coupled to a tractor; the second state becomes Used for trailer trains, if this is directly connected to a Tractor is coupled. Alternatively, the machine can drive yourself. ,

A single chain chain conveyor. 12 is attached to the front of the frame 10; the chain is provided with ball engagement projecting 13. The conveyor is pivoted at 14, do a movement between the illustrated position for picking up bales from the ground and a horizontal one Allow position to receive the bales directly from a baler. A spiked take-up drum 15 is attached to the front of conveyor 12 to aid in picking up the bales. The sponsor is with Side guide rods 16 equipped.

At the rear end of the conveyor 12, the bales arrive a stationary table 17, preferably made of open metal wire mesh. A spiked drive wheel is drivingly attached to an arm 19, which is at 20 " pivotally attached and by a hydraulic ram 21 is movable. The arm is moved down to a position in which the wheel 18 has a ball on the table get into engagement and this backwards into the enclosure of two of four ordering quadrant arms 23 can move. An outer part circular guide wall 24 limits the Length of the bales accepted by the ordering arms 23. The arm trim and bale are through the hydraulic ram 22 rotated by 90 ° in order to align the bale with its length laterally to the machine and to move on a lifting table 29.

A hydraulic 'ram 30 is in operation to the bales located on the table 29 upwards into a block

30983371449

formation area 31 to move through upper and lower elements 32, 33 and through front and rear Elements 34 »35 is intended. The elements can form a housing with side plates (not shown) or can simply be guide arms that are sufficient to define a block without individual bales slipping out to allow. The punch 30 moves a bale upwards through an opening 37 »past spring-loaded claws 38, to prevent the bale from falling or falling back.

It can be seen that a subsequent bale moved upward on the table 29 with each preceding bale, which is held by the claws 38, engages and lifts it. This way it becomes a pillar formed with a desired number of bales, that is, four or five. When the column is ready, get there the rams 40 in operation in order to actuate the element 41 for moving the entire column backwards by a ball width. A second bale column is then on the front Formed at the end of the area 31 and after its completion, the punches are operated again around the two columns to move back a bale width. When a desired number of pillars, that's four or five, are completed, the block is complete.

The pad is bound as follows: A roll 50 of Binding material, that is nylon knit or steel band, is provided on the hanger 10 next to the lifting table 29. A not the knotter shown is also arranged at this point. Before a block is started, a knotter needle pulls a length of binding material across the mouth of the opening 37 and holding the end to the leading edge of the opening tight. It is obvious that when one another-

309833/0449

The following bales arrive in area 31, the binding material is withdrawn from the roll to finally encompass the entire block. When the block is done the knotter links the ends, cuts the material and pulls a new length across the opening 37. Two rollers and two knotters are preferably provided, to provide the block with two parallel bonds.

The bound block is reversed by the punches 40 emotional. Pivoting doors 50 open and the block 51 shown in broken lines slides smoothly towards the Earth down when the machine moves forward. Pie doors 50 then close in a suitable manner Spring preload. In an alternative embodiment, the bound block on the soil 33 forming tines can be vertical to be lowered to earth.

The machine is operated by pressure switches or other triggering mechanisms controlled and synchronized, which in turn control the operation of the various described control hydraulic ram. Thus, each arm 23 can be a push switch for contact by pad end faces have to trigger the ordering of the arms by the punch 22. The completion of the ordering is easily scanned and then the arm 19 can be lowered by the punch 21 to cause the wheel 18 to move on to the next Pad in the enclosure of the next pair of arms 23 to drift. The conclusion of the organizing arm movement triggers the application of the stamp 30 in a convenient manner, to lift a bale into area 31. A pressure switch can also be provided on element 32. to sense when a column of bales is ready to trigger the operation of the punch 40. Another switch at element 35 indicates the completion of a block,

30,983 3/04 49 ^; -

which can trigger the operation of the knotter. The conclusion the knot can trigger the release of the doors 50 ..

A block of twenty bales was chosen as a convenient size because twenty bales are generally about 500 kilograms weigh and can therefore be safely handled by a conventional tractor front loader.
