Abstract

Multi-seed multi-function seed drill with automatic adjustment by means of hydraulics or electricity, simultaneously sowing seeds in rows to be cultivated, and broadcasting between the rows using a motorised vehicle, the seeds to be cultivated being sown by a disc-type seed drill (seed-spacing drill) (160) and protected on each side by movable protectors (29). Outside the protectors in the gap between the future plants are broadcast seeds allowing the digestion of excess nitrates, phosphates and the like in the soil, as well as seeds, the plants of which will attract good and bad insects so that they can lay their eggs, the larvae eating each other. The broadcast seeds are sown by rotary plates (19) (19b) driven by hydraulic or electric motors (3) (7). The automatic adjustment and displacement of the plates and of the seed-spacing disc assemblies is carried out by means of threaded shafts (42) (43) of different diameters entrained by hydraulic motors or the like allowing displacement according to the spacings of the plants to be cultivated.

Description

MULTIGRAINE MULTI-GRAIN SEEDER WITH AUTOMATIC ADJUSTMENT
SEEDER with autsmatic adjustment to squeeze seeds of different sizes at different line intervals to carry out the sowing to be cultivated as well as the sowing of specialized plants to digest and block nitrates, phosphates and others ..., between sowing in rows ( any salt element etc ... not digested by the plants of the culture carried out and the seeds for plants attracting insects to realize their ponteobons and bad insects). the automatic adjustment of the intervals thus made enables seeds to be cultivated and seeds to be sown on the fly between the intervals.

These seeds sown on the fly are between the cultivated rows, they are intended to digest nitrates, phosphates and others ... and also seeds whose plants attract good and bad insects to effect their laying which will allow the larvae to devour each other and thus exterminate each other. An adjustment system with 2 perforated discs allows all seeds to be sown to be sown without changing discs by adjusting the two superimposed discs (according to patent n 91.08508)
These different known seeds sown in the rows will make it possible to recover by digesting different mineral salts, fertilizers and others which are so eroded that go into rivers, streams and groundwater. These seeds as well as those which are sown specialized to attract and lay good and bad insects when they have grown to a certain level will be mechanically destroyed by a "ROTOSAR-
CEEUSE "which will put these plants in extremely fine elements in the soil, which will make it possible to recover all the mineral and other salts which will be assimilated by the plants of future crops.

This cultivation system will block almost all of the water-soluble elements and will avoid the use of weedkillers and pesticides, thus obtaining an economical and healthy culture.

BOARD 11/11 - FIG. 11 - Automation of the intermediate adjustment between carrots and corn.

All the parts are placed on a metal support (beams 9-10-11- (8789- - 90 and 84-86 - 85 forming a rigid frame (vbir coupe G board 7/11 and 8/11) On this frame sliding beams will be placed in groups of two, ie (12-13) (14-15) parallel supporting on each side hydraulic or electric motors 1-2-3-4-5-6-7-8. 6-7-8 are placed on the 2 rear beams 12-13 spaced to let the shafts of the so-called movable motors pass. On the front the motors 1-2-3-4-5 are placed on the 2 front beams I4- I5 spaced apart to allow the shafts of said mobile motors to pass through. These motors are intended to cooperate on two lines.

The rotary beams of the front line cooperate with the rear assembly to define a variable working width corresponding to a space between 2 cultivated lines. The rotary assemblies can move towards each other coming, in extreme cases (minimum space) arrange themselves on the same longitudinal line to sow on the fly the necessary seeds.

In the case of larger sowing space (males, beets, etc.), the said rotary units will move in opposite directions, so that the rear rotor only sows part of the surface from the front assembly up to the maximum spacing where the 2 widths worked are adjacent, the rotary assemblies moving in staggered rows.

To ensure these movements, hydraulic or electric rotary assemblies
I and 2 as well as the protectors 25 26-27 will be placed on the shafts 64-66 on the threads 42 by means of a nut 46 and moving to the left towards the center (front view plate 4/11)
A protector is located on one side of the front assembly and a protector on the opposite side of the rear assembly.

The hydraulic or electric rotary assembly 5 and 8 as well as the protectors 32-33-34 will be placed on the shafts 63-65 - 67-69) on the threads 42 by means of nuts 46 and will move to the right towards the center.

The hydraulic or electric rotary assembly 6 integral with the protectors 28 and 29 will be placed on the shafts 68-70 on the threads 43 by means of nuts 47 and will move to the left towards the center.

The hydraulic or electric rotary assembly 4 integral with the protectors 30. and 3l will be placed on the shafts 63-65 on the thread 43 by means of nut 47 and will move to the right towards the center.

The hydraulic or electric rotary assembly 3 and 7 is not attached to any protector, the plants being protected by protectors 29 and 30.

The motor 3 is placed on the shafts 64 and 66 on the thread 44 by means of a nut 48 and will move to the left.

The motor 7 is placed on the shafts 67 and 69 on the thread 44 by means of a nut 48 and will move to the right.

To allow the driver to operate the machine properly, a probe will be placed at the front of the tractor, enabling him to be warned when the latter has a deviation from driving, by an audible warning and by a visual screen on his control panel. on board near the steering wheel, these feelers act on induction coils which, by phase shift, open a circuit which can be audible or visual.

Explanation of a unitary motor assembly allowing to sow on the fly between the mobile protectors 25 - (26-27) (28-29) (30-31) (32-33) 34.

The mobile motor 3 will be fixed on a plate 17 supporting the motor which itself will be placed on the intermediate piece 18 of well-defined shape to rest on the beams 14 and 15 which will include needle bearings I6 which will allow the motor to slide freely. (See section 7/11 the axis of the hydraulic or electric motor is fixed on a transmission shaft 22, the other end of which is fixed on a rotary support plate 19. This rotary assembly (shaft) and plate I9 is placed in a tube 23 centered by bearings 24 forming the support for the transmission element of the rotary table The rotary table I9 centered by the bearings 24 where long blades I9a and short I9b are placed and fixed is used for seeds on the fly. sowing equalization)
This rotating unitary unit which can move is integral with a protective sheet 29 having a base 91. The protective sheets are fixed to the rear by means of a support adjustable in height (50 by the screw 52). The sheets 45 and 50 are fixed to the protectors @ by the welds 54, the rnabile assembly 36 is moved manually vertically by the crank (55) or by a hydraulic motor and on the front by a vertical adjustable sliding support I08 by the screw I09 manually by the crank I04 or by a hydraulic or electric motor placed on a support I05 via a reniai of angle I06 and gear. for adjusting the height between the bottom of the protective plate and the I9 rotary sowing disc. The crank I04 can be replaced by a hydraulic motor. For a good understanding, a machine with 8 4-row motors has been designed (see plates I / 11 to 10/11 for an automatic horizontal adjustment with hydraulic locking.

The protectors avoid squeezing the seeds on the fly in the space reserved for the seed of the plants to be grown sliding on 41 by bearings 40.

Motors I and 2 are integral with protectors 25-26-27.

Motors 5 and 8 are integral with protectors 32-33-34
Motor 6 is integral with protectors 28-29
The 4 D engine 30 - 31.

Motors 3 and 7 are not attached to any guard, the plants being protected by guards 29 and 30.

The motors I and 5 will distribute the seed with an I / 2 row on each opposite side of the machine and will each be joined by 2 protective sheets, i.e. the hydraulic motor n I sheet 25 and 26 n 5 of sheet 33 and 34 .

In some cases, the sheets may have a manual adjustment system for spacing between them (spacing between 25 - 26 and 33 - 34 etc ...).

These motor sets and mobile protectors, automatically adjusted, make it possible to obtain a modification of the width of the parts to be sown on the fly while retaining the seeded seed area which is protected, that is to say the always regular space for protecting the plants to be cultivate between the protective sheets 26-27 28-29 30-31 32-33 with sheets 38 pivoting around 39 to level the ground.

Between the protective plates, i.e. 25-26 27-28 29-30 31-32 33-34. these protectors delimit the seeds of seeds sown on the fly.

The mobility of the hydraulic motor assemblies of the motorized rotary disc (seed on the fly) is indicated by transmission shafts. In this case boards 4/11 5/11 6/11 or (63) 64) (65-66) (67-68) 69-70) in this case have threads 42-43-44.

These trees will be threaded with different pitches on different diameters depending on the movement of the rotary assemblies required for the different spacings of the crop to be sown. The motors will be placed on one or two or more transmission rods. According to the case of the drawing for explanation there are two of them, that is to say that the motors will be placed astride the two. Each mobile assembly (motor and seedbed) rotary disc will be fixed by nuts of the same thread as the threaded shafts on each side allowing a regular and parallel movement on the threaded shafts.

These threaded shafts (63-65) 64-66 67-69 68-70 will be fixed to the frame by means of sealed bearings or bearings and will be placed in parallel LEs (71 to 76) - (92) - (114 to 126). (127 to 130) (I34) (I37) and I44.

Boards 1/11 (maize setting) 2/11 (beets setting) 3/11 carrots setting D cut (see board 7/11) show the motors 1-2-3-4-5-6 7-8. The protective sheets are represented by the following parts 2526-27-28-29 30-3I 32-33 and 34.

The boards 4/11 setting but 5/11 setting beets, 6/11 setting carrots each represent the different positions given as an example for sowing the seeds to be cultivated.

The cultivated seeds are stored in the reserve I62 fed by the cover. These are distributed by a single-grain distributor 160.The seeds are sown in the soil via the base I6I. This base is connected by a flexible I5I pipe to obtain the treatment of the seed in the soil against insects and others.

The seeds sown on the fly specialized for digesting, nitrates and phosphates etc and the seeds whose plants attract good and bad insects are sokée in the reserve 20 fed by the cover I46 and distributed by flexible pipes I49 and 150 to the discs distribution I9 and projected by long and short blades I9 a and I9 b. The storage reserves 20-21-88 are equipped with an adjustment system I53 - I54 and I55 allowing the flow to be closed or regulated.

The I62 hoppers for storing the seeds to be cultivated are placed below between the protectors 26-27 28-29 30 - 31 32-33.

The hoppers are secured by the support 94 of the discs I63 covering an axis 93 and the support 95 of the scraper 164 to cover the seeds.

Each hopper is equipped with a pneumatic or other single-grain distributor.

The perforated discs are driven by the wheels I65 and I38 by exagonal steel bars I74 sliding in the exagonal tubes I75. These tubes will allow the width adjustment of the machine by the displacement of the bases
I6I and wheels I65 and I38.

The disks of the pneumatic single-grain distributors are connected to the vacuum turbine I56 provided with a filter I57 by means of a distributor 158. The pipes I59 are connected to each single-grain distributor 8/11 - 9/11 - IO / ll.

The wheels I38 and I65 of soil setting are rrobile they move by a crank I39 - I69 which turns a threaded rod I70-92 fixed by bearings
I4I-97 I7I - I8 3. This threaded rod allows the mobility of the wheels by the threaded support of the wheels. The cranks can be replaced by hydraulic motors or electric motors. To distribute the fertilizers in the soil before sowing the seed by the I6I base, a mini 177 base is placed before
I6I on support I76.

To obtain different distances of seeds from each other for an equal forward speed, a multiplier system I73 will be placed between the wheels I38-I65 which will make it possible to obtain different distances without changing the perforated discs. THE Multiplier will be adjusted by a control rod I80 manually or automatically which will make it possible to vary the speed between the soil wheels I38-I65 and the shaft I74 secured to the perforated seed disc.

The section CC '(see plates 4/11 5/11 6/11) shows the arrangement of the motors and the adaptation on the threaded shafts 42-43-44 by nuts 46-47-48 corresponding to a thread dimension and of the threaded shaft pitch. The nuts 46-47-48 are integral with the motors I-2-3-4-5-6-7-8.

The assembly allows to obtain the necessary displacement of the motors following the mechanical adjustment according to the spaces of the cultivated plants. example carrots, beet, corn or others ...

To obtain this displacement, the threaded shafts must be rotated in the direction indicated by the hydraulic or electrical rectors 35 and 37 which are supplied by a hydraulic or electrical unit and which are identical (same rotation in revolutions minutes).

(Section AA 'board 8/11 9/11 10/11) see (section GG' board 7/11
The motor 37 will rotate the threaded shafts 63-65-67-69 in the same direction.

The motor 35 will rotate the threaded shafts 64-66-68-70 all in the same but reverse of the motor 37 (boards 4/11 S / Il and 6/11).

To obtain a precise and rapid adjustment, fixed distributors or contactors 111 will be placed 113 that can be mobile and that can be mobile for intermediate adjustments between the minimum and the maximum. (plates 8/11 9/11 10/11 He / He
The distributors or contactors 111 - 113 are placed to be controlled by an arm 112 placed on each motor which will come to bear to effect the opening of the bypass circuit of the circuit supplying the motors 35-37 for the maximum and minimum adjustment to obtain , the interval settings for
cultures from 0.20 to I. OOML.

To obtain the adjustment of the intermediate spacings between the minimum and 230 the maximum the distributors or contactors will be placed on a slide and can thus be moved manually or automatically by a vee allowing precise adjustments between the maximum and the minimum of the possible widths, for example between the carrot malset setting and if necessary the batter-following the boards 3/11 5/11 and 9/11 but the machine can have all the settings from minimum to maximum between the two extremes.

When the adjustment is made either automatically or manually the
mobile work elements (seed discs on the fly) must be locked to be precise and avoid vibration. The blocking is carried out
I / HYDRAULICALLY and AUTOMATICALLY for all the mobile working elements by a simple operation using a distributor supplying a
cylinder on each movable element.

Each movable element has a small jack 59 which, once supplied, does
pressure on the chassis and blocks the moving element when it receives pressure
