Description

 The present invention relates to a semi-automatic distribution device for planting seedlings in clods, in particular soil or potting soil for horticulture and market gardening.

More precisely, it is a device for planting clods sprouted and prepared in advance.

 the preparation of clods requires great care its burial is a delicate operation, especially since the implementation of clods thus prepared becomes expensive, given the cost of current labor.

 We hatched devices to perform this type of operation. Generally speaking, these are formed by a tubular chassis of parallelepipedal shape mounted on wheels in which a worker introduces the clod which slides on an inclined plane and settles on the ground or else the clod, is brought in by strip and then taken by pliers which deposits it on the ground.

 We realized, however, that these possibilities of planting were not sufficient, C2is thus, that at the time of planting, the root ball remained stuck and the planting was done once in two, which in the area of profitability presented difficulties.

 The present invention intends to remedy these drawbacks by proposing an improvement to these known machines by which the conditions for depositing the clod in the ground are significantly improved and, as a result, the device thus allows staggered seed.

To this end, the invention relates to a semi-automatic pneumatic distribution control device for planting seedlings in clods. Generally speaking, this consists of a tubular chassis, the coupling side rests on a drum having the role of drive and controls the pneumatically controlled distribution device; o it is connected to the tractor by its three attachment points, at the other end, the chassis rests on two carrying wheels
According to one of the main characteristics of the invention, C1 is the working part of the assembly, which is automatically controlled by a pneumatic distributor supplied by a compressor which is connected to the tractor by the PTO.

The aforementioned distributor controls a plurality of pneumatic cylinders
In a preferred embodiment of 19invention7 the jacks are provided with drawers controlled alternately by cascades at three levels, so as to make the clod fall perpendicularly into the chute and thus make up for bad positioning during work, this operation requires a lot of care.

 Finally ejt advantageously, the last cylinder stripped the clod in the earth after the base has made its furrow.

 The above-mentioned base has a particularly studied shape so that the root ball is deposited behind it and is then buried by double tamping wheels.

 Each wheel, which has a well-defined pressure angle, closes the furrow after the soil clod has gone; Note that the device has as many equipped chutes as there are bases.

 The invention will be better understood during the description given below, by way of purely indicative and non-limiting example which will make it possible to identify the advantages and the secondary sarsct6ristics.

Reference will be made to the appended drawings in which:
- Figure I, in a longitudinal zchematic view, illustrates a Semi-automatic distribution device for spreading planes into clods.

 - Figure II is a top view of the nomi-automatic distribution device for planting seedlings in clods.

 Referring first to Figure I. we see in the longitudinal view, a tubular parallelepipedal chassis I in mechanized-sounded represented schematically in the form of a frame which rests on a spar on which is fixed an adjustable telescopic assembly 2a whose roller 2 has the function of driving wheels driving a variable pulley 3 integral with said driving wheel, the latter drives another variable pulley 5, driven by a belt 4; the above pulley drives a cam 6 integral with it.

 Note that chassis I has a standardized three-point attachment system that adapts to the tractor via the welded legs Ib and lo.

The originality of this device resides in the fact that this device uses automation, namely that the cam 6 controls a distribution valve 7 which is connected to a compressor 8 connected to the tractor by the foros outlet 9
Said compressor sends compressed air to a tank 10.

A pipe II is grafted onto the said tank and is connected to an Ila distributor, a cover I2 covered with this assembly.

 The said distributor controls 3 double-acting cylinders I3 - I4 - 15. These three cylinders are arranged on a mechanically welded "trunking - base" assembly.

 This chute 16 is held by a m6cano-welded connecting piece 17a - I7b which is mounted on a crosspiece 18, which allows it to be transversely adjusted, the screw 19 allows the blocking of this assembly.

 A special base 20 is welded at the end of the chute, said chute has an opening I6a at the end, which allows the clod 21 to escape therefrom.

 Note that the chute has strips 22 22a judiciously distributed along the chute, oe which allows the root ball, when it goes from one floor to another, to be deposited perpendicularly on the drawer 23 which slides in a guide 23a .

 Depending on the scenario used or needs, the machine passes into five or six trunking-school assemblies distributed over the width of the machine.

 A desk 24 protects the assembly and makes it possible to store the boxes of clods ready for use.

 Each furrow corresponds to a pedestal assembly and each set has a train of two compacting wheels 25 adjustable in width and in height, distributed on each side of the axis of the furrow.

 These said wheels are connected to the chassis by a mechanically welded assembly 26 which slides on a cross-member 27. Above these wheels, a set of boards 28 is disposed on the chassis I and acts as a bench. An element in the form of a welded frame 29 is assembled to said chassis, which will be connected to the load wheels.

 Note that opposite to the coupling system, the complete chassis is supported by two wheels 30, these are adjustable in width and in height by a telescopic screw system 31, which allows the angle d to be adjusted. incidence of plinths relative to the ground.

 Figure II illustrates a preferred embodiment of the chassis in the form of a rigid mechanically welded frame, as well as a coupling device shown in Ib - Ic known in itself.

 On the coupling side, we see the roller 2 with driving function and the height adjustment system 2a as well as the arrangement of the servo service grouped in 7 - 8 - 9 - IO- 11. The adjustment of the combined chute - plinth system 16 - 20 s 'performs transversely on the on the cross member I8.

Note further, the adjustment of the compacting wheel train 25, which is carried out independently of one another with respect to the axis of the groove, as well as the transverse displacement of the latter. all of the above-mentioned wheels 25 can also be adjusted in the weight,
At the end of chassis I, we can see the telescopic adjustment system 31 allowing the device in question a trim correction.

 We see that avo the device according to 11 invention, we can vary at different points the height of the machine and this independently of the hitch, without forgetting the multiple possibilities of transverse adjustments mentioned above These different settings cited in reference allow to improve certain efforts acting directly on the tractor, this thus avoiding premature wear of certain members as well as certain breakages known in the profession.

 The invention finds an interesting application in agriculture in general, horticulture and the vegetable industry.

 It is not limited to the description which has just been given, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.
