Description
The concept of this mechanically welded invention, which meets European demand in certain fields of soilless cultivation.

 Some soilless cultivation, like the strawberry currently grown in a greenhouse or in the ground, receives intensive treatments whose flows pollute the soil, groundwater, springs, and rivers.

 The collection of ripe fruit by a highly experienced workforce in the bent position and difficult to recruit.

 It is a mechanically welded assembly according to the invention makes it possible to remedy these drawbacks, while respecting the ecology and can improve the biological field, it indeed comprises, according to the first characteristics, a metallic structure which forms a frame which can allow baskets carrying chains to enter into rotation, so the operator in a sitting or standing position according to his comfort at his workstation, by a control box brings the baskets containing the fruit to his height and can thus carry out his pickup in the best conditions and in complete safety. According to particular embodiments, the frame can constitute a pyramid so as to have the baskets forming a staircase which goes up or down at the request of the operator, or can in a variant be constituted horizontally.

 The accompanying drawings illustrate the invention.

 Figure 1 shows the device of the invention from the front.

 - Figure 2 shows in section.

 - Figure 3 shows the basket overall and in section.

- Figures 4 and 5 represent a horizontal variant With reference to these drawings, the assembly comprises a mechanically welded structure (5) with reinforcements (6) in a star forming a triangular frame (Figure 2), a drive axis (1) provided with 2 notched wheels (2) fixed on the frame by 2 rolling bearings (4), serving to drive 2 carrying chains (7) of baskets (12), at the base of the frame 4 free wheels (15) mounted on 2 axes serving as chains guides.

 The baskets (12) can be suspended by 2 adjustable chains (11) at each end, hooked by hooks to pivoting axes (13) themselves housed at their ends in a yoke (14) serving as chain axes (16 ).

 An electric or hydraulic motor (3) controlled by a fixed or mobile control unit (10), allowing the slow rotation of the axis (1) and load-bearing chains (7).

 The stability of the assembly can be ensured by 2 plates (9) for a fixed frame, or by a plate and a wheel (8) for a movable frame.

 The baskets can be of different rectangular, round, right triangle shape, that shown (figure 3) and rectangular can be lined with soil or small pots of plants, equipped with an automatic watering device (B) fitted with a dropper. drop or fine rain spray (C), thus form an effective watering. A retractable sleeve (D) allows the connection between the basket and the water inlet (A) fixed on the frame (5), watering is always done when the work is stopped the opening can be done by a water supply programmer with products added.

 The bottom of the basket can be fitted with a drainage and geotextile filtering system (F), to recover product residues (E) in order to be able to recycle the solution collected in a tank, or to analyze it in order to be able to reload it of products if the need is before putting it back into the sprinkler system.

 An ecological and efficient way to fight pollution while reducing the cost of production.

 By way of nonlimiting example, for the pyramid type frame will have dimensions of the order of 2.80 m in height, 5 m in width, 4.50 m in length, dimensions variable according to the number of baskets, for the frame of the horizontal type the height 0, 90 m the length from 4 m to 150 m, the dimensions of the basket width 25 cm the height 20 cm length from 2 to 6 meters.

 A fairing will be on all the moving parts, such as chains, sprockets, motor, so as to present maximum safety for the personnel. The workstation can be fitted with small conveyor belts to evacuate the fruit without disturbing the operator, any other arrangement can be made at the request of the user.

 The equipment according to the invention is particularly intended for cultivation above ground, ecological biological while improving working conditions, intended for professionals or individuals.
