SU388701A1 - DEVICE FOR INTRA SOURCE DISTRIBUTION OF LIQUID POTENTIATIVES AND FERTILIZERS - Google Patents

Description

one

The invention relates to the field of agricultural plant engineering, in particular, to devices for applying liquid chemicals and fertilizers.

According to the main author. St. No. 328859, a device for subsurface introduction; 1and liquid chemicals and fertilizers, including a tank for working fluid, a pump, a pressure line connected by a drain line with: rezbruvoir and through a pressure valve with a working body in the form of a monitor nozzle. A shock valve of a hydropercussion device is installed at the entrance of the slyn line. However, it is noted that during operation, the frequency of injection of working fluid into the soil is not regulated.

In the proposed device, a HITOKOM impact valve is equipped with a shaped cam drive or a probe controlled cam interacting with a plant, under which the injection of liquid chemicals or fertilizers is carried out.

FIG. 1 is a schematic diagram of the proposed device; FIG. 2 - position of the profiled cam at the moment of injection into the soil; in fig. 3 is a basic cam control scheme.

A device for the subsoil shaking of liquid chemicals or fertilizers consists of a tank / for working fluid, pumping

station 2, pressure pipeline 3, equipped with a hydropercussion device 4, working bodies 5 in the form of washing nozzles connected by a drain line 6 to the tank

for working fluid. The hydraulic shock device contains a shock valve 7 with a rod 8 and a main valve 9. Above the shock valve stem a shaped drive valve is mounted on bearings 10,

controlled by probe 12, interacting with the plant, under which the working fluid is injected. The probe is indicated 13 and the lever 14 is connected to the profiled cam. In the initial position, the probe and the non-shaped cam are held by the spring 15.

The device works as follows.

With the open impact valve 7 working

the fluid supplied by the pump 2 in the pressure

pipe 3, through the drain line 6 is poured into the tank. When the profiled cam 11 is rotated, the impact valve abruptly closes. As a result, a hydraulic impact occurs, and the liquid through the discharge valve 9 and the working body 5 is injected into the soil. By setting the speed of rotation of the profiled cam, the frequency of injection of liquid chemicals or fertilizers can be adjusted.

In the case of the application of the proposed device for the application of liquid chemicals or fertilizers in gardens, the operation of the profiled cam is controlled by means of a probe interacting with the plant. When the probe is deflected by the plant 12, the lever of 14 tons, the gog 13 turns the cam //. In this case, the shock valve closes abruptly and the working fluid is injected into the soil. When the probe is deflected, the device operates in automatic mode, i.e. the working fluid is periodically injected. After the termination of the effect of the plant on the schuo spring 15, the cam returns to its original position, which, acting on the rod 8, returns the shock valve 7 to the lower position. The working fluid pumped by the pumps 2, through the drain line 6 v. Sings into the tank /,

Subject invention

1. Device for the inside. Soil application of liquid chemicals and fertilizers. St. No. 328859, characterized in that, in order to make it possible to control the frequency of moisture in the soil and fertilizers into the soil, a profiled drive cam is installed above the stem of the percussion valve.

2. A software device according to claim 1, characterized in that, in order to be able to control the Frequency: the injection of liquid dohimicates and fertilizers directly into the root system of the plant, the profiled cam is connected by means of a spring-loaded lever with a probe interacting with the plant.
