Description

The invention relates to agriculture, in particular to feed production.

A mobile unit is known (see AS No. 2061387, class A23K 3/03), which includes a gripping device with injectors mounted on the tractor’s attachment system, a preservative tank, a pump with a piping system for supplying preservative to the injectors, and a dosing device consisting from the control hydraulic cylinder, the cavity of the hydraulic system of the tractor’s hinged system and on the rod of which the stop is rigidly fixed, and the control hydraulic cylinder, the control hydraulic cylinder is made in the form of a cylinder with two separated baffles with a central hole a cavity, one cavity of which is equipped with a piston, on the spring-loaded stem of which a circuit breaker for controlling the pump operation is installed, and is connected to the pressure line through a valve, and the other cavity is connected by one pipe to a preservative container, and the other with a pressure line, and is equipped with an elastic with a membrane covering the inlet from the pressure line, the control hydraulic cylinder is mounted above the control hydraulic cylinder, and the rod of the control hydraulic cylinder is coaxial with the control rod idro cylinder.

The disadvantages of this mobile unit is that the injectors are located on the upper part of the gripping device and the preservative is unevenly distributed over the plant mass. The preservative is effectively applied only to the upper layers, next to the injectors, and the lower layers are not completely processed.

The closest analogue to the claimed device is the OVK-F-1 mobile unit to the PRP-1,6 baler (Proshkin S.N., Manasyan S.K., Demsky N.V. Krasnoyarsk State Agrarian University, Achinsky Branch, “ Machines and equipment in crop production ”, 2011, 231-232 pages), consisting of a tank, a piston metering pump, a suction pipe, a valve, a rod with four spray nozzles, a preservative dose regulator, hoses and pipelines. The tank is mounted on the bottom of the baler, the metering pump on the right wall, and the rod above the conveyor.

The disadvantage of this device for introducing preservative preparations into the plant mass is the impossibility of changing the dose of preservative application, the uneven distribution of the preservative over the incoming plant mass with the untimely opening of nozzles due to the actuation of the preservative supply mechanism, when the roll is already formed in the baler chamber.

The problem solved by this invention is the uniform and timely supply of liquid preservative to the incoming mass of the baler.

The tasks are achieved in that a device for introducing preservative preparations into the plant mass containing a container for preservative, a pump with a piping system for supplying preservative through electromagnetic nozzles, a metering device, a pressure regulator in the form of a safety valve is installed in the supply pipe, and the metering device is made in in the form of electromagnetic nozzles electrically connected to a positional switch interacting through the side surface of a larger diameter cylinder a device rigidly connected to a cylinder of smaller diameter, with the possibility of interaction of the latter with the clamping grille of the baler, while the central axes of these cylinders are offset from each other by h.

New significant features.

1) A pressure regulator in the form of a safety valve is installed in the supply pipe.

2) The metering device is made in the form of electromagnetic nozzles electrically connected to a positional switch interacting through the side surface of a cylinder of a larger diameter rigidly connected to a cylinder of a smaller diameter.

3) The possibility of interaction of a cylinder of a smaller diameter with the clamping grille of the baler.

4) The central axis of the cylinders of larger and smaller diameters are offset relative to each other by h.

The listed new essential features in combination with the known ones are necessary and sufficient to achieve a technical result in all cases to which the requested scope of legal protection applies.

A pressure regulator in the form of a safety valve is installed in the supply pipe to stabilize the set pressure in the piping system and to safely operate the constant pressure pump.

The dosing device is made in the form of electromagnetic nozzles electrically connected to a position switch interacting through the side surface of a larger cylinder, rigidly connected to a cylinder of smaller diameter with the clamping grille of the baler, designed for timely opening of nozzles with the supply of a liquid preservative through them, at the time of receipt plant mass into the space between the clamping grid and the feeding device.

The possibility of interaction of a cylinder with a smaller outer diameter with the clamping grille of the baler, under the action of which the cylinder of a larger diameter is moved and a signal is supplied to the position switch.

The central axes of these rigidly fixed cylinders are offset from each other by a value of h in the installed position on the baler, which allows you to transfer the movement of the clamping lattice, interacting with a cylinder of a smaller diameter, and to transfer the offset due to rigid coupling to a cylinder of a larger diameter, to to which the position switch is installed.

The technical result consists in the stabilization of a given pressure in the system, the completeness of the distribution of preservative over plant mass and the simplicity of the manufacture of the constituent parts of a constant pressure pump.

Figure 1 schematically shows a device for making preservative preparations in the plant mass.

Figure 2 schematically shows the cylinders of larger and smaller diameters, rigidly interconnected with the displacement of the axes.

A device for introducing preservative preparations into the plant mass containing a container for preservative 1, a constant pressure pump 2 with a piping system 3 for supplying preservative through electromagnetic nozzles 4, a metering device 5, a pressure regulator 7 in the form of a safety valve and a metering valve are installed in the supply pipe 6 the device 5 is made in the form of electromagnetic nozzles 4, electrically connected with the position switch 8 through the side surface of a cylinder of a larger diameter 9, rigidly connected with qi smaller diameter indrome 10 through a plate 11, rigidly connected with both cylinders 9, 10, with the possibility of interaction of the outer surface of the cylinder of smaller diameter 10 with the clamping grid 12 of the baler, while the central axes of these cylinders 9, 10 are offset relative to each other by h. The plant mass enters the baler chamber using a feed device 13.

A device for introducing preservative preparations into the plant mass works as follows. When the tractor is operating, the constant pressure pump 2, connected to the tractor’s general electric network (not shown in the figure), creates constant pressure in the piping system 3, which is directly regulated by the pressure regulator 7, made in the form of a safety valve. In the feeding device 13, when the plant mass enters the baler, the pressing grid 12 changes its position and moves upward, acting on the lateral surface of a cylinder of a smaller diameter 10, which transmits movement by means of a rigid connection 11 to a cylinder of a larger diameter 9, which includes a position switch 8, thereby opening the electromagnetic nozzles 4. In this case, the preservative, through the piping system 3, enters the electromagnetic nozzles through the metering device 5.
