Description

Self-propelled device for growing plants

arranged in lines.

  The present invention relates to a self-propelled apparatus for the cultivation of plants arranged in lines. Various self-propelled devices are known for the maintenance, pruning, etc. of plants cultivated in rows, for example the vine, these devices comprising a small chassis mounted on tracks and comprising at the rear.

  a stretcher comprising the controls of a driving motor

  tracks and an auxiliary motor for operation

  of the tool carried by the chassis.

  These devices are very practical, but present

  try various disadvantages. Indeed, the payload is

  very small, they work in line spacing, have a

  ble power and their use is tiring for the use

  tor. One of the aims of the present invention is,

  in particular to remedy this drawback.

  The apparatus according to the invention is of the type

  taking a frame mounted on tracks and a drive motor

  dragging the tracks, said apparatus being characterized in that the frame comprises two platforms arranged above the tracks and connected by a hoop, the motor being carried by one of the platforms and driving a series of pumps, two of which are each connected to a motor

  hydraulic, each hydraulic motor being kinematically connected

  only a caterpillar, while the second platform

  is arranged to selectively receive tools and

  carries a hydraulic motor, the output shaft of which constitutes a power take-off for driving said tools, said hydraulic motor being connected to the pump driven by

engine.

  Thanks to this arrangement, a provision is made

  which allows you to work across the line

  culture. The device can be very compact and easy to use.

  transportable in a van.

  According to a constructive detail, the arch is

  hollow and forms a reservoir for hydraulic fluid.

  Thus, there is at its disposal a large reserve of oil and the platforms remain clear to receive tools.

  According to yet another characteristic, the ap-

  similar includes at the rear two steerable wheels arranged behind the arch and carried by arms articulated on the frame on horizontal axes perpendicular to the longitudinal axis of the device, jacks being inserted between the arms and the frame and means being provided for controlling the jacks. Thus, the device comprises means constituting a support avoiding the rearing and also the rocking effect

  when the aircraft climbs a slope.

  Preferably, the engine is a heat engine.

  According to a particular detail, the apparatus comprises

  two distributors suitably inserted in the hydraulic circuits, one of which is intended for controlling the two

  track motors, while the other controls the

  the hydraulic motor, the output shaft of which

tituates the PTO.

  Finally, the platform comprising the motor is

provided with a seat.

  The invention will now be described in more detail with reference to an embodiment.

  particular given by way of example only and representing

  tee to the accompanying drawings, in which: Figure 1 is a schematic elevational view

  of a self-propelled apparatus according to the invention.

  Figure 2 is a back elevation view of

the device of figure 1.

  Figure 3 is a schematic view of the system

device hydraulics.

  The apparatus shown in the figures is made up of

  killed from a frame 1 comprising two platforms 2 and 3 re-

linked by a roll bar 4.

  The platform 2 comprises, inwards, S15 a vertical part 5 extended by a cheek 6. In the cheek 6 are spun two shafts 7 and 8, on the shaft 7 being wedged a driving wheel 9, while on the shaft 8 turns an idler wheel 10. The wheels 9 and 10 receive

  a track 11 which is guided by a train of rollers 12.

  The shaft 7 constitutes the output shaft of a mo-

hydraulic 14.

  The platform 3 is made in the same way as the platform 2 and its vertical part Sa is extended by a cheek 6a supporting two shafts 7a and 8a, on the shaft 8a being idle mounted a wheel 10a for guiding a track 11a, while the shaft 7a constitutes the output shaft of a

hydraulic motor 14a.

  The arch 4 is hollow and constitutes a reservoir

for hydraulic fluid.

  Platform 2 supports a heat engine,

  17, a seat 18, a control assembly 19 for maneuvering

  with tracks 11 and 11 and a distributor 20.

  The seat 18 can be folded down so that the user

  The reader can drive both the seated and the standing machine.

  Between a side of the arch and an arm 21 is inserted a double-acting cylinder 23, said arm being, at one end, mounted to pivot on an axis 24 carried by a yoke 25 secured to the platform 2, while the other end is extended by a bend 27 at the free end

  which freely rotates around a substantially vertical axis

  a support 28 on which a wheel 29 is mounted idly. On the side of the hoop adjacent to the platform 3, a second cylinder 23a is provided which controls an arm

  21a supporting a wheel 29a mounted like the wheel 29.

  The motor 17 drives by its output shaft two main pumps 34 and 35 and an auxiliary pump 36. The pump 34 supplies by lines 38 and

  39 the hydraulic motor 14 with interposition of the distributor

  stopper 19, while the pump 35 supplies by conduits

  tes 40 and 41 the hydraulic motor 14a with interposition

distributor 19.

  The distributor 19 has two levers 42 and 43 which can occupy three positions. A first position in which each of the pumps sucks the oil from the reservoir 4 through a filter 45 and discharges it via a return line 46 into the reservoir

  4, the motors not being supplied; a second posi-

  tion in which the motors 14, 14a are supplied in one direction and a third position in which said motors are supplied in the other direction. We can thus advance the device in one direction or the other and

  run it since the motor control is inde-

  pending. Pump 36 draws oil from the tank

  4 through the filter 45 and discharges it into the distri-

  striker 20 through line 50, oil returning

  to reservoir 4 via line 51.

  The distributor 20 comprises a series of handles

  tes 52 to 56, the lever 52 controlling the cylinder 23 in the direction of its shortening through a pipe 57, while the lever 53 controls the elongation of said cylinder 23. The handles 54 and 55 respectively control the shortening and the elongation of the jack 23a through the lines 59 and 60.

  The distributor 20 is connected to a hydraulic motor.

  lique 62 by a pipe 63, the return being made

  by a pipe 64 connected to the pipe 51.

  Of course, there are check valves

  return as is usually done.

  The hydraulic motor 62 is arranged on the

  platform 3 and has an output shaft 65 which

tituates a PTO.

  As can be seen in FIG. 2, the platform 3 is entirely cleared and can thus receive different tools 66 (shown diagrammatically in phantom in FIG. 2), for example, a trimmer making it possible to prune the vine laterally and in height , a sprayer, a spreader, a grinder, etc ..., these different tools being

  connected to the PTO 65, the motor 62 being com-

  mandated by the handle 56 of the distributor 20. The various tools can be fixed by bolts 67 which are screwed onto the platform 3. It is also possible to provide flanges

  or straps on the platform 3.

  The device can have very small dimensions.

  and be transportable in a van.

  The device is very practical to use, not only for the vine but also for all

plants grown in rows.

  The wheels 29 and 29a make it possible to constitute

  an adjustable support on the ground to avoid any nose-up.

  These wheels 29 and 29a also make it possible to remove

  the rocking effect when the device climbs a stop.

  Of course, the invention is not limited

  to the embodiment which has just been described and represented

  feel. We can make many modifications

  detail without departing from the scope of the invention.
