Description

The utility model relates to agricultural engineering, in particular to devices for subsoil liquid fertilizer application.

A device for applying liquid fertilizers to the soil is known (RF patent for the invention No. 2421973, IPC АСС 23/02, publ. 06/27/2011), including a container for liquid fertilizers, a compressor, discharge drums with hollow needles freely mounted on the hollow axis. The compressor is connected directly to the liquid fertilizer tank, which is connected to the hollow axis by the discharge line. In the hollow axis, there are segmented windows for supplying liquid fertilizers from the liquid fertilizer tank to the needle cavity. Hollow needles have cutoff rods at the bottom.

Disadvantages: does not provide the ability to work in various rows of cultivated plants.

Known combined unit for soil treatment and the application of liquid organic fertilizers (RF patent No. 2352095 for an invention, class IPC АСС 23/02, publ. 04/20/2009), which contains a frame, cutting discs, filling nozzles, leveling roller, tank, pressure pipeline, switching device, pressure hose and pipe manifold. The disks are arranged in four rows with the concavity of the disks of each subsequent row of the opposite concavity of the disks of the next row and are cut out. Each cut-out disk is equipped with an individual elastic suspension. The nozzles have deflector nozzles and are mounted on the convex side of the second row of discs. The cross-sectional area of the collector is equal to the sum of the areas of the filling nozzles.

Disadvantages: the unit does not provide the ability to work in different rows of cultivated plants.

The closest in technical essence and the achieved positive effect to the claimed device is the injection module (patent of the Russian Federation for utility model No. 179995, class IPC АСС 23/02, published on 05/30/2018), which contains a frame with vehicles intended for coupling to a vehicle wheels, on which the rod is mounted with injection wheels fixed with brackets. The module brackets can be made of two parts: the rigid part and the spring part. Fine filters and a working fluid supply pump connected to the injection wheels using a working fluid supply pipeline can be installed on the module frame. Fine filters can be installed in the frame mounted on the frame. To aggregate the module, a trailed sprayer equipped with a pump for supplying a working solution and a device for regulating the norm of a working solution can be used. As a vehicle, a container on wheels can be used.

Disadvantages: the unit does not provide the ability to work in different rows of cultivated plants. And the large dimensions of the bracket from the frame to the point of attachment of the spring will lead to damage to cultivated plants.

The technical result is the ability to quickly rearrange the injection wheels on the rod, both for continuous processing, and for the processing of row-spacings of various widths, the processing of a row both on one side and on both without injuring the plants.

The specified technical result is achieved due to the fact that the soil injector containing the hitch frame, designed for hanging on the sprayer frame onto which the working solution tank, coarse and fine filter is installed, a pump, a computer-controlled working solution regulator connected to the injector collector, a pump sprayer hydraulic systems, a system of pipelines and hoses, characterized in that a multi-section rod with a hydraulic system for folding and unfolding sections is installed on the hinge frame, with the number of sections of at least four, interconnected by means of a swivel, each section of the rod contains manifolds with shutoffs, in each of which throttling washers, rigidly attached brackets are installed, with the possibility of installing injection wheels using removable brackets, each of which includes an intermediate plate in which a fixing end of a spring is mounted between the two latches, secured by a pressure plate by means of a bolt connection, to reduce ravmirovaniya crops all the plates and brackets are rounded.

When switching from continuous processing to row-spacing, the number of injection wheels 3 is reduced. The brackets 4 for each row spacing are painted with their own color.

Rearrangement of the injection wheels 3 is as follows.

In continuous machining with an interval of 450 mm, the injection wheels are mounted on brackets 4 welded to the frame through 225 mm. With a row spacing of 700 mm, the injection wheels 3 are attached to the brackets 4, welded to the frame through 225 mm and through 475 mm.

An intermediate plate 6 is attached to the bracket 4 with bolts, an injection wheel spring is thrown onto the tubular retainer 8, and the mounting end of the spring is placed between the two clamps 9 and secured by a bolt connection using the pressure plate 7.

The presence of significant features distinctive from the prototype allows us to recognize the claimed device as new.

The possibility of implementing the inventive device in industry allows us to recognize the device as meeting the criterion of industrial applicability.

To the brackets 4, by means of bolts, removable brackets 10 are attached, each of which includes an intermediate plate 6, in which a fastening end of the spring of the injection wheel 3 is fixed between the two clamps 9, which is fixed by the clamping plate 7. The intermediate plate has a tubular clamp 8.

To reduce injury to cultivated plants, all plates and brackets are rounded.

Soil injector works as follows.

The soil injector is hung on the sprayer frame, which in turn is attached to the tractor. From the power take-off shaft, the working solution pump and the sprayer hydraulic system are driven.

A soil injector with a folded multi-section rod 2 is transported to the field for agrochemical work. On the field using a hydraulic system 5, sections of a multi-section rod 2 are connected to each other by means of a swivel joint; the linkage frame 1 is lowered to its working position. Working solution is poured into the sprayer tank through a coarse filter. The selection of the working pressure and speed of the unit establish the required rate of application of the working solution. The flow rate of the working solution is regulated by the flow regulator through the on-board computer of the sprayer and the adjusting washers located in the collector shutoffs. Then the pump for supplying the working solution is turned on and the movement of the tractor with a sprayer and soil injector begins. The working solution from the tank through the fine filter is pumped through the flow regulator and the piping and hose system to the collector, with shutoffs located on it. Then, through the throttling washers, nozzle and hose, the working solution flows to the hub of the injection wheel 3 and to the needles. Needles of injection wheels 3 are pressed into the soil and the working solution is injected into the soil.

When switching from continuous processing to row-spacing, the number of injection wheels 3 and the interval between them are reduced. The brackets 4 for each row spacing are painted with their own color.

Rearrangement of the injection wheels 3 is as follows.

In continuous machining with an interval of 450 mm, the injection wheels are mounted on brackets 4 welded to the frame through 225 mm. With a row spacing of 700 mm, the injection wheels 3 are attached to the brackets 4, welded to the frame through 225 mm and through 475 mm.

An intermediate plate 6 is attached to the bracket 4 with bolts, an injection wheel spring is thrown onto the tubular retainer 8, and the mounting end of the spring is placed between the two clamps 9 and secured by a bolt connection using the pressure plate 7.

The use of the inventive soil injector will provide the ability to quickly rearrange the injection wheels on the rod, both for continuous processing and for the processing of row-spacings of various widths, processing a number of both on one side and both without injuring the plants.
