Description

MACHINE FOR THE PRODUCTION OF CHANNELS FOR HYDROPONIC CULTURE.

Object of the invention

The present invention relates to a machine for the production of gutters of those that are used in hydroponic cultivation in bulk in greenhouses and the like, the gutter being made from a sheet metal coil.

Field of application of the invention.

The field of application of the invention is the construction of equipment for intensive agriculture, more specifically the manufacture of gutters for hydroponic cultivation for use in greenhouses.

Background of the invention.

Currently hydroponic crops have been extended in the field of intensive agriculture and greenhouses. Fruit and vegetable crops using hydroponic techniques increase production yield considerably, but require specific means and equipment to perform these crops efficiently.

In some cases, these hydroponic crops are usually carried out in longitudinal gutters that allow the placement of the plants in such a way that the fruits are easily accessible by lateral inclined wings and the plant is housed in at least one inner hollow of said gutter. This gutter allows the circulation of water with nutrients throughout its length, supplying each plant.

However, the use of these gutters presents serious installation problems, since these gutters are manufactured with factory folding machines and are made of a limited length, which allows their handling, and transport to the greenhouse or place of use. Once these gutters are formed, they are bulky and complicated to handle as they increase in length.

These gutters are installed in the greenhouses using legs or supports that allow their continuous assembly in an elevated position. This aligned mounting of the gutters is designed for maximum use of water with

nutrients that are used, taking into account the large dimensions of

greenhouses, and facilitate the collection of fruits and vegetables, These gutters are joined

each other directly with specific joints or joining means, than with the

time the hydroponic irrigation water leaks open or suffer.

5

In other cases, the gutters are placed independently and made

water passage connections between them, which raises serious constructive problems

and loss of the planting substrate in the connection areas.

Description of the invention

1 o

The machine for the production of gutters for hydroponic cultivation,

object of this invention, presents some technical peculiarities intended to facilitate

Its construction in continuous.

The machine comprises a sheet feeder, means of

thrust of the sheet and a roller train forming the gutter, which is

fifteen

ejected once made by an exit, said raceway being made

with sheet of galvanized steel or aluminum, for example.

According to the invention the machine comprises:

a support frame, which presents at one end the sheet feeder

supplied by a coil and the pushing means of the sheet, and then the

twenty

Stream forming roller train in sequence along the frame,

being at the opposite end of the frame the outlet of the channel already formed to

its direct placement on the appropriate supports in the greenhouse,

a transport platform for the support and displacement of the frame

during the conformation of the gutter in situ.

25

In this way, the machine can easily be taken to the greenhouse and

place it at the beginning of the area where the gutter is to be installed. Once the

machine starts producing the gutter in situ, and the length of this gutter can

be any at will and limited by the length of the sheet rolled in the coil, the

which can have an extremely long length for the needs

30

raised. This machine also offers the advantage that the gutter is installed

directly after making, saving storage costs and

Logistics problems in your transportation. This machine is especially suitable

for use in large greenhouses, which require the use of cultivation gutters

hydroponic large, and that benefit from a confection and installation on site

of the one-piece gutter, without joints or intermediate connections.

The platform comprises traction means connected to some

platform wheels for the autonomous movement of the machine. So by

For example, the machine moves as you make the gutter

5

that remains immobile on the appropriate supports in its final installation site. Though

it is not ruled out that the machine is towed by an external vehicle to carry out

said displacement.

In one embodiment, the sheet feeder comprises cylinders

parallel swivels on which the sheet coil is placed, of such

1 o

so that as the sheet is consumed the supply is produced by the

own coil rotation. This coil, arranged at the top of the frame is

move with the whole machine, easily setting up a compact group

scrollable In addition the placement of the sheet coil is much simpler and

fast with a single crane, without the need to operate any axis on which to skewer the

fifteen

coil.

In one embodiment the thrust means are associated with the train of

rollers by chains and sprockets, these being arranged on one side

preferably. The pinions have suitable diameters for adjusting the

feed rate of the gutter as it passes through the different rollers of

twenty

conformation.

The train rollers are interchangeable to form different gutters.

In this way the same machine can form different types of gutters according to the

use that will be given to them, such as single, double or other gutters.

Description of the figures.

To complement the description that is being made and in order to

facilitate the understanding of the features of the invention, is accompanied by the

present a description of a set of drawings in which, for illustrative purposes and

non-limiting, the following has been represented:

30

Figure 1 shows a sectioned elevation view of the machine

during the production of a gutter.

Figure 2 shows an elevation view of the machine being observed

the thrust means, chains and pinions of movement of the roller train.

Figures 3 to 6 show cross sections of different

gutters made by the machine.

Preferred Embodiment of the Invention

As can be seen in the referenced figures, the machine

5

comprises a frame (1) of tubular frame and prismatic shape, mounted

horizontally on a transport platform (2), being in this

platform (2) traction means (21) connected to lower wheels (22) of

the platform (2), which allows the autonomous movement of the machine during the

continuous preparation of the gutter (C).

1 o

The frame (1) comprises at one end a raised area in which

Find the sheet feeder (11), with rotating cylinders (12) on which

the coil (8) of sheet metal used to make the continuous gutter (C) is placed.

Below this sheet feeder (11) there is a pushing means (3)

associated with a roller train (4) forming, and moving the sheet from the

fifteen

coil (8). The roller train (4) is mounted horizontally below,

in a progressive sequence, these rollers (4) being associated with the means of

thrust (3) by chains (31) and sprockets (32). On the opposite end of the frame

(1) there is an exit (13) of the channel (C) formed, following the train

of rollers (4) forming.

twenty

This roller train (4) has a plurality of rollers (4) of

progressive conformation, and which are removable for exchange and realization of

different configurations of gutters (C), of which several examples are represented

in figures 3 to 6. This roller train (4) facilitates the advance of said sheet and the

conformation of the gutter (C) progressively and gradually as the

25

platform (2) moves the machine, leaving the gutter (C) that is supplied to

through the exit (13) at a suitable height for its placement supported on some

lifting supports (S).

Once the nature of the invention has been sufficiently described, as well as

an example of a preferred embodiment, it is stated for the appropriate purposes that

30

Materials, shape, size and arrangement of the elements described may be

modified, as long as this does not imply an alteration of the characteristics

essentials of the invention as claimed below.
