Description

OBJECT- DEVICE

Mkl, A 01C 23/00 Unit for applying liquid fertilizers

The utility model relates to agricultural machinery, in particular, to machines for self-loading, transportation and distribution of liquid fertilizers.

Known machines for applying liquid fertilizers, including a tank, a filling device with a suction sleeve, a pump with a valve and a reflective shield and a vacuum device. In these machines, the tank refueling is drained by creating a vacuum directly in its tank with the help of 1; an ejector (1), it works; it is from the exhaust gases of the engine, the pump is vacuum (2), and the fertilizer is fed from the tank to the reflective shield by creating pressure in the tank or pump.

This method of refueling and application requires increased strength of the tank body and special elliggic bottoms, which leads to increased material consumption and higher cost of the product.

In addition, the use of an ejector to create a vacuum directly in the tank due to its significant volume negatively affects the operation of the energy engine, since the latter works in backpressure mode. The use of pumps for these purposes significantly complicates and increases the cost of the machine.

The objective of the utility model is to simplify the design, reduce material consumption and cost.

The task is achieved by the fact that in the proposed unit, consisting of a power tool with an exhaust manifold, a tank, a filling device with a suction sleeve, a pump with a valve and a reflective shield and an ejector, the pump is connected by a vacuum pipe to the ejector chamber, connected to the intake sleeve of a filling device and equipped with a pipeline one end of which is movable relative to the pump nozzle and the other is equipped with a shutter for shutting off the neck of the tank.

The accepted design of the unit, based on the fact that the pump is connected by a vacuum pipe to the ejector chamber, is connected with the intake part of the filling device and the tank, allows for technological operation) to load the tank without creating a vacuum (vacuum) in the latter.

The execution of the pipeline from the pump to the tank movable relative to the pouring nozzle and equipping it with a shutter allows the pump to be used to perform two techno-operational operations: self-filling and distribution of fertilizers.

Thus, it becomes possible to harden the design of machines for applying liquid fertilizers and reduce their material consumption and cost by reducing the thickness of the walls of the tank, some other elements and removing from the design of vacuum pumps, drives, hoses.

Figure 1 presents the schematic diagram of the unit, view c6oKj; in FIG. 2- front view (section AA).

The unit (figure 1) consists of a power tool 1 with an exhaust manifold 2, a reservoir 8, a refueling device 9 with a suction sleeve 10, a pump 5 and an ejector 3. The pump 5, consisting of a rotor sealed and located in it, is attached to the tank 8. The rotor drive of the pump 5 from the power take-off shaft (V OM) of the power unit 1. An ejector 3 is mounted on the exhaust manifold 2 of the power unit, connected by a vacuum pipe 4 to the pump cavity 5. In addition, the pump 5 is connected to the tank 8, on the one hand, a pipe 7, an opening which periodically cross is closed by a valve 6, and on the other hand, by a movable pipeline 11. equipped with a shutter 12 at the inlet of the tank (Fig. 2). To the pump 5 is also connected to the intake 10 of the filling device 9.

The control of the pipeline 11 and the valve 6 is carried out, for example, from a hydraulic system of an energy facility.

The unit operates as follows.

The unit pulls up to the place of refueling, and the intake rztsav 10 is lowered into the storage with fertilizers. From the PTO, the energy means drive the rotor of the pump 5.

The window connecting through the pipe 7 the reservoir 8 with the cavity of the pump 5, block the valve b, and the inlet of the movable pipe 11

connected to the discharge nozzle 13 of the pump 5. The hole NC of the movable pipe 11 in the tank 8 is closed by a shutter 12.

The ejector 3 is activated, which creates a discharge in the cavities of the pump 5 and the intake hose 10. Due to the created vacuum, the liquid fills the cavities, and the rotating blades of the rotor of the pump 5 through the discharge nozzle 13 and the movable pipe 11 feed fertilizer into the reservoir 8. wherein the shutter 12 opens under pressure created by a stream of liquid. When liquid enters the reservoir, the ejector is turned off.

After filling the reservoir, the PTO is turned off, the shutter 12 automatically closes the hole from the movable pipeline and the reservoir. The intake pZkav is lifted from the storage and set into transport position. The unit is sent to the place of application.

In the process of application, a PTO is turned on, a valve 6 is opened that connects the reservoir 8 to the cavity of the pump 5, and the pouring nozzle 13 is connected to the atmosphere by lifting the movable pipe 11. The rotating rotor blades of the pump 5 through the window of the pouring nozzle 13 distribute the fertilizers along the field surface.

Using the proposed unit for self-loading, transportation and applying liquid fertilizers allows you to reduce the material consumption of the machine by 10 ... 12%, and reduce the cost of the product by 15 ... 20%.
