Description

The invention relates to agricultural machinery, in particular to the separation and collection of particles of the soil flow in width and height.

A device for the separation of grain heap [1].

The device for separating grain heaps contains a grain heap thrower, a pneumo-separation chamber with oppositely placed windows, an air inlet input window and an impurity output window with a channel, a clean grain fraction collector separated by partitions located one above the other with height adjustment in the grooves of the initial part of the collector fractions, an air flow source connected to a pneumatic flow channel in which an air flow divider is installed, made in the form of two independently rotating dampers mounted on a common axis. The throw-in grain is formed into a grain stream, which flies through the separation zone due to the difference in the aerodynamic and inertial properties of individual grains, the grain stream is divided into fractions that move along different trajectories into the clean grain collector.

The disadvantage of this device is that it can only be used for a formed stream of air and bulk material.

A device for processing and receiving grain heaps [2]. A device for processing and receiving grain heap contains a feeder, a grain heap thrower, a pneumatic separation chamber with a grain heap input channel and a clean grain output channel, an air stream channel with an air flow source, an impurity output channel, a grain hopper consisting of grain receiving sections, an aeration channel with a conveyor and an air supply channel, a louvre bottom, an air chamber, an air flow generator, an additional air duct, a discharge conveyor. The throw-in grain is formed into a grain stream, which flies through the separation zone due to the difference in aerodynamic and inertial properties of individual grains, the grain stream is divided into fractions that move along different paths into different sections of the clean grain collector. Impurities are discharged by the air flow through the channel for removing impurities outside the pneumatic separation chamber.

The disadvantage of this device is that, it can also be used only for the formed stream of air and bulk material.

Also known is the working body for applying mineral fertilizers at the same time as soilless tillage [3], which is a prototype of the claimed technical solution. The working body for applying mineral fertilizers simultaneously with the soilless cultivation of the soil containing a wide-grip flat-cutting paw mounted on a rack with pipelines, a distribution chamber in the form of a closed two-wing duct of variable cross section located along the width of the paw and having outlet openings on the rear wall. A removable selector box with an open front wall is attached to the latter, divided by partitions into separate cells. The length of the box is equal to the width of the working body and is attached to it using detachable joints. On the back wall of the box there are openings for air outlet. Mineral fertilizers from the fertilizer sowing apparatus come to the working body and, under the action of the air flow, are directed to the outlet openings, from which, leaving, they are poured into the cells of the pick-up box. After passing the set distance, the unit stops, the working body is transferred to the transport position, and the box-selector is removed. Then fertilizers are poured into containers from each section of the selection box, they are weighed, and the distribution of fertilizers is uniformly distributed along the bottom of the furrow.

The disadvantage of this working body for applying mineral fertilizers at the same time as the soilless tillage is that it can be used only with the soilless tillage, with a depth that ensures the stability of this type of working bodies.

The objective of the proposed technical solution is the determination of the optimum amount of soil required during operation of the milling section of the turf seeder, which ensures the established thickness of the soil layer above the seeds and its fractional composition.

The problem is solved due to the fact that the sod seeder contains supporting and driving wheels and rear wheels, a seed box with sowing devices and their drive, rolling rollers, a drive drive for seed machines, a milling section having working elements in the form of disks with tillage knives, a mechanism for adjusting the depth of processing, a casing, in the back of which behind the working elements in the form of disks with tillage knives, a removable multi-level tool is installed over the entire width and height of the casing external trap, consisting of a frame and receiving cells located vertically one above the other, which can be removed separately from each other.

A removable multi-level trap collects particles of the soil flow over the entire width and height of the casing into the receiving cells to determine the distribution of the flow of soil particles over the height and its particle size distribution. The receiving cells are the same in height and can be removed separately from each other.

The inventive turf seeder is illustrated by drawings.

Figure 1 shows a seeder sod, side view; figure 2 - milling section side view; figure 3 is a removable multi-level trap, side view.

A sodder seeder containing supporting-driving 2 and rear 3 wheels located on the frame 1, a seed box 4 with sowing devices 5 and their drive 6, rolling rollers 7, a drive gear for seed sowing devices 8, a milling section 9 having working elements in the form of disks 10 (Fig.2), tillage knives 11, a mechanism for regulating the depth of processing 12, a casing 13, in the rear of which behind the working elements in the form of disks 10 and tillage knives 11, a removable multi-level trap 14 is installed over the entire width and height of the casing 13, consisting from frame 15 (Fig. 3), in which receiving cells 16 are mounted vertically one above the other, which can be removed separately from each other.

The seeder sod works as follows.

The milling section 9, mounted on the frame 1 of the sod seeder, mechanically processes the sod with working elements in the form of disks 10 and tillage knives 11, intensively grinding it. In the process of grinding, soil particles moving under a casing 13 along certain flight paths, fall into the receiving cells 16 installed in the frame 15. After a predetermined distance has passed, the turf seeder stops, is transferred to the transport position by means of a hydraulic system, and a removable multi-level trap is removed 14. Then from of each receiving cell 16 of a removable multi-level trap 14 pour the collected soil particles into a container, weigh them and determine the particle size distribution and distribution of the flow of soil particles you are in height.

The advantage of a multi-level trap over the prototype is expressed in the collection of particles of soil flow along the entire width and height of the casing into receiving cells to determine the optimal amount of soil, when the milling section of the turf seeder provides the established thickness of the soil layer over the seeds and its fractional composition.
