Description

Adapter for topical application of liquid fertilizers

Technical field

TT

BACKGROUND OF THE INVENTION The present invention relates to a universal additional adapter for a tractor or other energy means for topical application and incorporation, in particular, of liquid industrial fertilizers (KPH), respectively. other liquid chemicals to the soil when planting or even sowing broad-row crops, but also during early vegetation, especially when growing potatoes.

BACKGROUND OF THE INVENTION

Previously known embodiments of similar devices are designed as part of planters or seeders, ie they are specially designed for each type of machine from different manufacturers, mainly for solid fertilizers. These solutions do not allow separate application of fertilizer, eg before planting after row formation or or, for example, after planting potatoes or sowing other broad-row crops. Liquid fertilizers (KPH) are predominantly applied during vegetation by spraying on the leaf or before or during planting or sowing on the surface of the soil and vegetation. This results in loss of liquid or solid fertilizer by spraying or spraying into the air and soil, increasing its consumption. At the same time, there is a demand among growers for equipment that will contribute to limiting leaching of fertilizer applied mainly to the soil surface or by spraying foliar into surface and ground water and their pollution and thus to the protection of the environment. The required equipment is scarce.

SUMMARY OF THE INVENTION

These drawbacks are overcome by an adapter for topical application of the liquid fertilizer according to the invention, which consists of a frame with application tools in the holder, and a fertilizer tank equipped with a fertilizer tank, which is equipped with 9 9 9 • 9 9 9 9 99

999 99 999 9999 999 flow control unit with manifold and transport pump with electric motor, the whole adapter is powered by the towing machine.

The adapter according to the invention is characterized in that a height-adjustable and laterally adjustable application tool is attached to the frame, which is a coulter with an application tube or an injection wheel, and the application tool holder is provided with securing or supporting adjustable wheels.

The adapter according to the invention is further characterized in that the adapter frame makes it possible to connect it to an energy means, in particular a tractor, in a mounted and semi-trailer version by means of a front or rear three-point hitch. a planter, mower or other attached machine.

The adapter according to the invention is also characterized in that the tank for liquid fertilizers and other means is variably positioned by a sub-frame of the tank, mounted on the frame by pins and by a tank strut at the front on the front hinge or as a weight of the means.

The adapter according to the invention is characterized in that the connection of the application tube to the at least one manifold hose is made by a hose clamp, the manifold hose being provided with a drip nozzle and a strainer.

The adapter according to the invention is also characterized in that it is optionally equipped with removable connecting molding and inclusion bodies, which are fastened in height and laterally by means of a body holder on the frame of the molding body.

The adapter according to the invention is also characterized in that it is provided with a removable height-adjustable parking foot.

The adapter according to the invention consists of a base frame with mounted height and lateral and overload protected application coulters or other application working tools (for example injection wheels or the like), the number of which is determined by the number of rows of cultivated culture. Each coulter is provided with a stainless steel application tube with a plastic flexible hose inlet, which is fitted with a drip-proof nozzle with a strainer. The adapter is connected by means of plastic hoses to the central tank KPH located on the subframe of the tank and equipped with a distribution device with a transport pump, fertilizer flow sensors, allowing automatic control and adjustment of the required fertilizer flow through the system.

It is therefore advantageous to use tanks manufactured by different manufacturers for chemical sprinkler systems. The tank with automatic timing and hose system can be placed in front of the front linkage or in place of the front ballast on the tractor or directly on the frame or on the attached planter or seeder behind the power tool. The adapter makes it possible to connect to the tractor in a mounted and semi-trailer version using the front or rear three-point linkage and, via the lifting eye, the connection to the planter, seed or other attached machine. This solution allows connection to any type of machine, such as a potato planter or seed drill with a minimum connection distance behind the power supply. Depending on the planter type and number of rows, the universal adapter device according to the invention can be modularly extended and dimensioned for mounted, trailed, trailed planters and seed drills in the vegetable market or as a separate multi-row local liquid fertilizer applicator with row formation with attachable height and lateral formers . A removable, height-adjustable support leg is used to shut down the adapter. In the case of a trailer, the adapter according to the invention is equipped with adjustable swivel castors with lateral and height adjustment. For wider shots, this transport adapter can be equipped with a hydraulically operated folding arm (not shown) for transport position.

The adapter according to the invention can be used for local fertilization of plants into the soil even during vegetation in the cultivation of wide-rows of crops (eg corn, vegetables etc.). This avoids loss of liquid or solid fertilizer by spraying or spraying into the air and soil, reducing its consumption and increasing its use by the plant. The universal adapter according to the invention also contributes to limiting leaching of the fertilizer applied predominantly to the soil surface or by foliar spraying into surface and groundwater and their contamination, and thus to the protection of the environment. Working with the adapter according to the invention is simple, the adapter is easy to move and care and allows efficient and economical use of fertilizers.

Example of technical solution

The adapter according to the invention in FIG. 1 is composed of a frame 1, on which the coulters 2 with a fertilizer application tube 25 (or other application tools 19, for example injection wheels 26 and the like) mounted on the frame 1 by means of a coulter holder 20 with impact overload protection 3, rotatable supporting wheels 4 mounted on the side and height, mounted on the frame 1 by a support wheel holder 13. In plan view 2 and side view 3 a possible location of the central liquid reservoir 5 is shown. Fertilizer with sub-frame 11 of tank 5, attached to frame 1 by pins and strut 9 of tank 5. The tank 5 is equipped with a flow control unit 21 with a distributor 7 and an electric motor 8 with a transport pump 22. Fertilizer flow sensors allow information on flow and adapter operation according to invention. Adjustment of the required fertilizer flow is carried out by the flow control unit 21 with the distributor 7 and the electric motor 8 with the conveying pump 22, whereby a system of mainly plastic distribution hoses 12 transports the fertilizer to the coulter 2 with the application tube 25.
