DESCRIPTION:

BRIEF SUMMARY
TECHNICAL FIELD

The invention relates to the agricultural engineering, and in particular to an agricultural machine designed for seeding agricultural plants and for cultivation of young crop as well as for growing plants under artificial and natural climatic conditions.
The agricultural machine may also be used for harvesting.


BACKGROUND OF THE INVENTION

Known in the art is a process for cultivating plants without soil, in water-proofed containers, with the roots being disposed in a zonal system and being fed with a nutrient solution, the ionized air flow acting upon the top part of the plants. An apparatus for carrying out the process comprises a water-proofed container having a system of zones for accommodation of roots of the plants and means for supplying nutrient and ozone-air mixtures to the plants (cf. USSR Inventor's Certificate No. 897175, C1. 01 G 31/02, publ. 1980).
This apparatus is deficient in a low capacity and great labour effort in growing plants. The process capabilities are limited since the apparatus can only carry out one operation, namely, seeding of plants.
Known in the art is also an agricultural machine having a frame supporting a hopper for a fluid material and a device for causing the fluid material to move towards a working implement for carrying out production operations in the field, a motor comprising a milling cutter implement, a non-row seeding apparatus being provided downstream the implement and communicating with a seed duct of the seed hopper.
The seeding apparatus comprises a tube perforated along the entire length thereof, which extends horizontally transversely with respect to the direction of movement of the machine, the tube having a drive means for imparting reciprocations thereto in the direction along the tube axis (cf. USSR Inventor's Certificate No. 908262, C1. A 01 C 7/00, 1979). This apparatus can perform one production operation only, namely seeding of plants, the apparatus exerting a strong specific pressure upon soil since the frame moves along the field and carried reagents and a stock of seeds or seedings so that soil is overcompacted. Other auxiliary agricultural machines are necessary for fertilizing soil, harvesting and irrigation.


SUMMARY OF THE INVENTION

It is an object of the present invention to eliminate the above-described disadvantages of the prior art.
It is the main object of the present invention to create an agricultural machine maving a device for causing a fluid material to move, which would provide a fluid material supply to any point of a field being treated independently of motion of the agricultural machine.
This object is accomplished by that in an agricultural machine comprising a frame carrying a hopper for a fluid material and a device for causing the fluid material to move towards a working implement for carrying out production operations in the field, according to the invention, the hopper is located in a sealed chamber having an inlet communicated with a source of working fluid supplied to the chamber under pressure, the device comprising a driven drum having a flexible hose would thereon and accommodated in the sealed chamber in such a manner that the interior space thereof communicates with the hopper for a fluid material, the free end of the hose extending through an outlet of the chamber, being turned inside out and sealingly secured to and along the perimeter of the chamber so as to define an annular space, the volume of the annular space varying under pressure of working fluid to cause the fluid material to move.
This construction of the machine makes it possible to ensure supply of a fluid material to any point in the field being treated without moving the frame of the agricultural machine, the production capabilities of the machine being substantially enlarged.
The driven drum is preferably mounted on a shaft in a reversible manner so as to perform operations in the field during both work- and return travels of the working implement.
The hopper for a fluid material may be formed by the inner walls of the hose. T
