Abstract
- a bucket (4) fit to be rotated into the loading and distribution positions of the filling material;
- a distributing device (9) of the material to be spread;
- a rotating spreader (13);
- a ground touching device, that determines the automatic spreading of the material, when a wide dimension depression is detected. The touching device is adjustable, in such a way to allow the regulation of the intervention threshold.
Description
- The invention concerns a machine particularly fit for the maintenance of sport grounds, able to detect ground depressions and level tern by spreading suitable filling material, without modifying the due slopes.
- Currently the game ground depressions, caused by settling and treading, are manually filled with a shovel or with a net hauled by a device, and passed over the material previously put down.
- For closing small holes the manual intervention is effective, while for the substantial depressions such a intervention requires a lot of time and it would be difficult and inaccurate for obtaining also the modification of the expected slopes.
- The purpose of the present invention is to make more precise, more rapid and easy the levelling of game grounds.
- The machine herein described, hauled and driven by a small tractor, is equipped with a bucket rotating from the loading to distribution positions of the filling material, with a regulating device of the material to be distributed, with a rotating spreader and with a ground touch device, which provides the automatic material spreading, when a depression of substantial dimensions is detected.
- The touch device is adjustable, in such a way to allow the regulation of intervention threshold. In particular it is also possible to spread uniformly the filling material on the whole field, or to repeat this operations with time, without covering and choking the grass, in correspondence of a wide depression.
- The invention is described in detail, with reference to the attached drawings in which:
- figure 1 shows a side view of the machine, with the bucket at loading position;
- figure 2 shows a schematic view of the partially sectioned machine, with the bucket lifted in operative position;
- figure 3 shows a schematic top view of the machine, with some sectioned parts;
- figure 4 shows a view of the touch device and the related mechanism;
- figure 5 shows a top view of a part of the touch device;
- figure 6 shows a side view of an enlarged detail of the mechanism operated by the touch device.
- In these figures, numeral 1 indicates the drawbar, which is coupled to a small tractor, numeral 2 a cardan joint shaft, to be connected to the tractor power takeoff,
numeral 3 indicates the wheels. Numeral 4 indicates a bucket, supported by articulatedarms 5, hinged at 6 to the frame, figure 2. - The
arms 5 can be lowered or lifted by means of hydraulic jacks 7, to bring the bucket in loading position, as in figure 1, or in working position, as in figure 2. The filling material, contained in the liftedbucket 4, go down through alower opening 8 of this latter, in a controlled way, when a finned distributingcylinder 9 is rotated, figures 2 and 3. - The distributing
device 9 is hinged at 10 and is operated by a gearmotor 11, figure 3, by means of agearing chain 12. When the distributingdevice 9 is in a stopped position its fins, opportunely disposed, do not allow the material passage. - The material dropping from the distributing
device 9 in a controlled way, as further explained, is spread onto the ground by a spreader made up of a finnedconic disk 13, figures 2 and 3, that is rotated by means of theshaft 2, connected to the power takeoff of the tractor hauling the machine along the ground to be levelled. - The spreader rotates continuously, while the filling material is dropped from the distributing
device 9 only when necessary. - For this purpose a ground touch device is provided so as to locate automatically the zones in which the material has to be deposited. A
shaft 14, entirely independent from the examined mobile group, is provided with twowheels 15 at the ends, whose distance determines the width of the ground area where the control is made. - In the central part of the machine two touching
wheels 16 are provided that, together withrelated brackets 17 hinged in 18, lift and lower depending on the conformation of the ground to be levelled. Theshaft 14, supporting the twoend wheels 15, is supported bybrackets 19, hinged in 20. - The
touching wheels 16, by means of the oscillatingbrackets 17 and abase 21 integral therewith, act on arod 22 that is longitudinally moved onsupports 23, as better evident in figure 4 and in the detail of figure 6. On therod 22 is splined anadjustable sleeve 24, placed in such a way to start up theswitch 25, causing the start or the stop of the rotating distributingdevice 9 and therefore the spreading of the filling material. - For avoiding the spreading of the material also into small diameter holes, the distributing device activation is also checked by a timer, or however by a circuit giving the input only if the touching wheel movement is prolonged for pre-established time.
- Varying the position of the
sleeve 24 and the timer delay it is possible to define the machine automatic intervention ways, depending on the ground type and on the treatment to be done. In such a way the complete filling of a deep depression can be avoided, avoiding the choking of the grass. It is also possible to spread the filling material onto the whole ground. -
Numeral 26 indicates an actuator for the touching device lifting during the machine transfer. - The distributing container of the filling material can be constituted by the
bucket 4 itself, or can be placed in fixed position over thespreader 13. - The distributing
device 9 can be operated by means of a circuit controlled by a sensor, placed in such a way to detect the touching device position.
