Description
~05711Z
The invention relates to a machine for distributing materials. More specifically, it relates to such a machine having means for locking one of the wheels thereof.
The prior art teaches machines for distributing material wherein the overall width of the machines, as seen in the operating direction is greater than the overall length thereof, the overall length not exceeding the maximal permissible width of agricultural machines travelling on public streets and roads. Such machines comprise tools for laying the material upon the ground, and the tools are arranged in rows one behind the other and are adapted, in the operative condition, to be lowered and, in the transporting position, to be raised. The machine also comprises a frame supported at three points carried on running wheels, a towing device adapted to be attached frontally or laterally to the frame, and one running wheel arrangement in the form of a castor wheel arrangement, which castor wheel arrangement has a wheel pivoting freely through 360 about a vertical axis.
Such a machine is taught in U.S. Patent 3,884,309, Mr.
Emanuel Schneider, May 20, 1975. This machine is equipped with raisable and lowerable working tools in the form of shares and pressure rollers arranged in two transverse rows one behind the other. The ~rame of the machine is also supported at three points upon three running wheels, one of them located at the front and two at the rear of the machine, as seen in the operat-ing direction. The front wheel arrangement is in the form of a castor wheel arrangement having a wheel pivoting freely through 360, whereas the rear wheels may be changed over, by means of threaded spindles, so that they can roll on the ground either in the operating direction or in a transporting direction at right angles to the operating direction. Furthermore, the rear running wheels are secured detachably to beams adapted to be retracted into the frame so that, with the beams thus retracted, the overall length lOS711Z
of the machine does not exceed the permissible width of agricul-tural machines travelling on public roads and streets. The machine therefore requires no transporting vehicle to carry it through traffic, such as is required in many cases to move a machine from one worksite to another.
The great disadvantage of this machine is that converting it from the operating to the transporting configuration, and vice-versa, requires a considerable amount of effort and time. For example, the rear wheels, with their holders, must be expelled from their guides at right angles to the frame by actuating the threaded spindles, must be pivoted through 90, and must then be reinserted into the said guides. Changing over the running wheel holders also requires that the machine be jacked up with additional devices. Another disadvantage, in connection with the transporting configuration, is that the two rear running wheels are arranged at a considerable distance one behind the other, so that when the machine is travelling around a curve, at least one of these wheels must drag along the road at right angles to the transporting direction. This not only accelerates tyre wear but, which is far more serious, this movement of the wheels at right angles to the transporting direction becomes impossible if the road has deep ruts. This results unavoidably in the running-wheel holders and related parts of the frame being bent or broken.
It is the purpose of the invention to improve the known machine so that it can be quickly and conveniently set up for travel in the operating or transporting directions, and to provide trouble-free travel in both directions.
According to the invention, this purpose is achieve in that all the wheels are carried in castor wheel arrangements and in that the wheel of one of the castor wheel arrangements is adapted to be locked either in a transporting direction or in an ~~ operating direction at right angles to the transporting direction.
1(~571~
In accordance with a specific embodiment, a machine for distributing material, the overall width of the said machine, as seen in the operating direction, being greater than the over-all length thereof, the said overall length not exceeding the maximal permissible width for agricultural machines travelling on public streets and roads, the said machine comprising a frame, supported at three points, carried on castor wheel arrangements, and the said machine comprising tools, said tools being hingedly connected to said frame, for laying the material into the ground, the said tools being arranged in rows one behind the other and being adapted, in the operative condition to be lowered, and in the transporting position, to be raised, each said castor wheel arrangements comprising a wheel pivotable within its respective castor arrangement, through an angle of 360 about a vertical axis, a towing device, means for attaching said towing device either frontally or laterally as seen in the operating direction, to the said frame, said machine comprising means for locking the wheel of one of said castor wheel arrangements in a trans-porting direction at right angles to the operating direction;
and wherein two of said castor wheel arrangements, which two castor wheel arrangements constitute the rear castor wheel arrangements when seen in the operation clirection, are arranged upon the frame in such a manner that the two wheels thereof do not project laterally beyond the rearmost working tools when said two wheels are in the transporting position; is characterized in that said wheel of said one of said castor wheel arrangements comprises one of the two wheels, and further comprising means for locking said one of said two wheels in the operation direction as well.
Thus all that is required to convert the machine from travel in the operating direction to travel in the transporting direction is to attach a traction device to one longitudinal 1057~2 side of the machine and to lock the one castor wheel in the trans-porting direction after swinging it into the transporting direc-tion. It is a simple matter to pivot the castor wheels since, if the machine is moved for only a short distance in the transporting direction, all of the castor wheels will automatically swing into the said transporting direction. Thus, while the machine is travelling in the transporting direction, the locked wheel ensures that it tracks properly, this tracking of the machine being achieved, in the operating configuration, generally by the fact that the tools have been lowered into the operative positions.
~1)571~Z
The provision that the two rear castor wheels are arranged laterally upon the frame in such a manner that, with the machine in the transporting configuration, they do not project laterally beyond the rearmost working tools, as seen in the operation direction, has the advantage of making it possible for the working tools to be arranged in several rows one behind the other without increasing the overall length of the machine.
This also provides a larger free passage between the working tools, thus facilitating trouble-free spreading of the material onto the ground, even when the distance between the rows of tools is small.
The provision for one of the rear castor wheels to be lockage in both the operating and the transporting directions, and to roll, in the operating direction, on the edge of the track determined by the width of the machine has the advantage of making it possible to start spreading the material right at the edge of the field, without having to allow the lockable castor wheel to run on adjacent property.
According to one preferred example of embodiment of the invention, similar attachment elements for a towing device are provided on the front and on one side of the frame, as seen in the operating direction. This again facilitates the conver~ion of the machine, in that only one towing device is required for travel in both the operating and the transporting direction.
The invention is explained in greater detail in con-junction with the drawing attached hereto, wherein:
Fig. 1 is a side elevation of the machine according to the invention, and Fig. 2 is a plan view of the same machine.
The machine has a frame 1 carrying a divided storage tank 2 in the lower part of which is located a metering device 3. Working tools 4, consisting of shares and pressure rollers and arranged in three rows one behind the other, and shown in the lowered, operative position, are mounted pivotably upon frame 1, material being fed to the said tools from storage tank 2, through metering device 3, in accurately adjustable quantities, through hoses 5. As shown quite clearly in Fig. 2, tools 4, as seen in the operating direction, are staggered in relation to each other, the lateral distances between the said tools being equal.
Frame 1 is carried upon two front running wheels 7 and two rear running wheels 8, the said frame being supported on the front running wheels at one point 9 and on the rear running wheels at two points 10. These three support points provide a statically determined firm support for frame 1. Forward support point 9 is in the form of a bearing 11 which is fitted centrally to frame 1 and upon which a chassis 12 pivots in a vertical plane. The two front running wheel arrangements 7, designed as castor wheel arrangements, are arranged at the outer ends of chassis 12 in holders 13. Each castor wheel arrangement comprises a wheel pivotable through 360, in a horizontal plane, about a vertical axis 14. The two rear support points 10 are located on the two longitudinal sides of the machine and consist of holders 15, 15' for rear running wheels 8 which are also carried in castor wheel arrangements and pivot about vertical axes 14. Holders 15, 15' are detachable from frame 1. Finally, towing device 17 is arranged to pivot in a vertical plane, on the front of frame 1, by means of attachment elements 16, eye 18 of the said towi~g device being located ahead of the centre of the machine and being used to couple the said machine to tractor 19.
The arrangement of the front running wheels is such that they follow in the tracks of the rear wheels 20 of the tractor.
~i ~0571~2 These wheels therefore run smoothly even at high speeds, and the number of wheel tracks left on the field is reduced. Further-more, rear running wheels 8 are fi~ted to frame 1 in such a manner that they run on both sides of the machine on the two edges 21 of the track determined by the operating width 22 of the machine. This arrangement has the advantage of still further reducing the number of wheel tracks left on the field, since one rear wheel 8 will always run in the track left by one left wheel 8 during the previous pass down the field. It is also possible to work the field right to the edge, without having one wheel running on ad~acent property. However, if the rows are very close together, i.e. if there is little lateral spacing between working tools 4, right hand running wheel 8 must be fitted at a greater lateral distance from frame 1, so that it cannot come into contact with adjacent working tools 4 when the machine is in the transporting configuration, or if the machine is backed up, as is often unavoidable in making sharp turns.
In order to prevent working tools 4 from colliding with the left-hand running wheel 8, this wheel may be locked in operating direction 6 and in transporting direction 23 at right angles thereto. To this end, wheel holder 15' is equipped with a disc 24 having two recesses 25 arranged at right angles to each other. A bolt 26, mounted pivotably upon frame 1, may be held in either of these recesses by the force of a spring 27.
For the purpose of releasing the lock, the upper end of bolt 26 is connected to a hydraulic cylinder 28. When the hydraulic system is activated, bolt 26 is withdrawn from the relevant recess against the force of the said spring. After running wheel 8 has been swung into transporting position 8' indicated in dotted lines, the hydraulic system is deactivated and spring 27 snaps the lower end of bolt 26 into the other recess 25.
As may be gathered from Fig. 2, attachment elements ' 16 are also provided on frame 1 upon the right-hand side of the machine, the distance between these elements being equal to the distance between attachment element 16 on the front of frame 1.
In order to convert the machine for travel in transporting direc-tion 23, the machine is disconnected from tractor 19, towing device 17 is removed from front attachment elements 16 and is fitted to side attachment elements 16, thus assuming position 17' shown in dotted lines. me lock holding left rear wheel 8 is released. The tractor is now coupled to the traction device in its new position 17' and the machine is moved forwards for a short distance, causing running wheels 7,8 to assume positions 7',8' shown in dotted lines. By means of the hydraulic system, left rear running wheel 8 is locked in transporting position 8'.
The machine can now travel in transporting direction 23 like a normal dual-axle trailer, and the overall width 29 thereof does not exceed the maximal permissible width for agricultural machines travelling on roads.
Finally, rear running wheels 8 are fitted detachably in their holders 15,15'. The advantage of this is that in thé case of agricultural operations requiring no road travel, these wheels may be fitted detachably to the rear of frame 1 by means of simple, non-pivoting holders 30. In order to reduce the number of wheel tracks left in the field, these wheels are arranged to run in the tracks left by rear wheels 20 of the tractor.
The invention relates to a machine for distributing materials. More specifically, it relates to such a machine having means for locking one of the wheels thereof.
The prior art teaches machines for distributing material wherein the overall width of the machines, as seen in the operating direction is greater than the overall length thereof, the overall length not exceeding the maximal permissible width of agricultural machines travelling on public streets and roads. Such machines comprise tools for laying the material upon the ground, and the tools are arranged in rows one behind the other and are adapted, in the operative condition, to be lowered and, in the transporting position, to be raised. The machine also comprises a frame supported at three points carried on running wheels, a towing device adapted to be attached frontally or laterally to the frame, and one running wheel arrangement in the form of a castor wheel arrangement, which castor wheel arrangement has a wheel pivoting freely through 360 about a vertical axis.
