FR2464647A1 - Agricultural soil parasitic killer - has direct injection of steam in to soil via subsoil plough share - Google Patents

Abstract

The parasite killer injects steam directly into pre-loosened soil. The steam is injected via perforations in the shell of a hollow, sub-soil plough share. The steam can be supplied by a conventional steam generator, which either forms part of the same packed unit as the plough share, or is a separate unit. Tractor-mounted, the plough share can pref. be adjusted for depth of operation in the soil. The unit may comprise several plough shares injecting steam at different depths.

Description

The present invention relates to an "APPARATUS ANTIPARASITANT for soils by water vapor
It often happens, in fact, that crops are invaded by unwanted plants, insects or animals such as limacex worms etc ... which can affect the yield of the farm. - It is therefore essential to get rid of it .

To do this, chemical products or hormones are generally used which are effective but which are liable either to modify the soil, which requires receiving other crops, or to cause more or less serious digestive disturbances to the consumers of the products. harvested
The recommended method consists in treating the soil with superheated steam using injections which have an instant effect, without consequences for the future.

This injection will be made to a founder in relation to the nature of what is to be destroyed.

To be effective, the vapor must be able to penetrate profundely into the soil which therefore does not have to offer it too great a resistance and, if it is not a light earth, it must first be loosened by classic cultural buoys (plowing, harrowing etc ...)
The apparatus must therefore have two parts, on the one hand the steam generator which may be of a commercial type adapted to a commercial apparatus, and on the other hand the vanity injector in the ground.

The generator can be incorporated into the device and this is the general case, or be independent and it will then, in principle, be carried by the tractor. This solution is advantageous when the expansion may need a jet of steam. for other works.- Let us repeat it, the original part of the invention is not the production of steam but its use in the soil.

On the same principle, it will be possible to build various medels which may depend on the working conditions and the mode of traction used: the agricultural tractor for large or medium-sized areas, a simple tiller for market gardening work. , mounted or towed versions.

 The attached fig.I gives, schematically, a view of a nonlimiting example of embodiment of the invention; it is a monobloc, worn assembly, and for which the fuel used is the tuel for the production of steam is fuel oil.

 In this figure, the steam generator comprises all the parts numbered from (I) to (a) and which are contained in a frame (I3); it is the rest which constitutes the original part of the invention.

 The steam generator therefore consists of conventional elements, this is how (I) is the fuel tank - t2) the water reserve - (3) an adjustable pump ensuring constant pressure - (5) a tank buffer fitted with a pressure gauge- (6) a tap for adjusting the water flow - (7) the burner supply pump - (8) the burner- (9) the steam generator (plate or coil- (IO) the vareur duct to the ploughshare (II) the perforated ploughshare (I2) the plinth holder ((I3) the chassis containing most of the device.

 For the devices carried, the depth adjustment of the share will be easily done by the coupling in three points, on the other hand, nour a towed device, it will be necessary to envisage an adjustment which could be carried out by a sliding or interchangeable support, or even by making vary the height above the ground of the carrying axle.

@u again by any other conventional means.

Depending on the nature of the work required, and, in particular, the width of the strip treated on each pass, it will be good to have several types of soes.- Figs. 2-3-4-5- give some examples of cuts these soos. - The setting of the steam is done by the orifices (I4) which can be variously distributed on the different facets. above the hole, a metal tab (16) -fig. 6.

 Finally, for deep work, we can consider (fig.7) superimposed coulters, but offset.

 Nothing prevents, moreover, from mounting on the steam pipe (I0) a nozzle making it possible to collect superheated steam usable for other services, such as, for example, surface defects.

It is advantageous, during shallow work, to concentrate the steam on the ground, by mounting on the support (II) a sheet (I5) which will return the heat yes m @ ntait.

 All common fuels can be used for the production of steam.
