(54) DEVICE FOR WOODING FRUIT TREES

one

The invention relates to agricultural machinery, namely, machines for irrigating fruit trees in the zone of the trunk circle, as well as for superficial application of liquid fertilizers.

A device for introducing liquid fertilizers into the zone of the plant root system is known, comprising a fertilizer tank, a pump, a pressure line connected by a drain line to the tank and through a pressure valve to the working body in the form of a monitor nozzle. At the inlet of the drain line, a percussion valve of a hydropercussion device is installed, which is connected by a rod with a profiled driving cam connected by means of a spring-loaded lever with a probe interacting with the plant 1.

The principle of operation of the machine is that when the impact valve is open, the working fluid supplied by the pump to the pressure pipe is drained through the drain line into the tank. As the machine approaches the tree, the probe, interacting with its bole, deflects and rotates the cam. At the same time, the impact valve closes abruptly, and due to the hydraulic shock, the working fluid is injected into the soil.

This machine has the disadvantage that it can only work on a clean working fluid and apply fertilizer in small doses, since the process

injection takes place within hundredths of a second. In addition, this machine cannot, in continuous movement, produce watering of trees in the area of the near-bar circle with water consumption per tree 30-

40 l, i.e. increased dose.

It is also known a device for fertilizing the zone of a circle of fruit trees, including a tank, a high-pressure injection pump and

Spreading control system with pointing probe 2.

The principle of operation of the device is that with continuous movement between the rows of the orchard, the probe of the system

control at the meeting with the tree boom is rejected and through the leverage system turns on the water supply under high pressure (100-150 atm). The high-pressure jet of water, forming a hole in the soil and capturing particles of dry mineral fertilizers in the mixing chamber, is directed at high speed directly into the zone of the root system of the plant.

However, the known machine has a low productivity, since fertilizing the resulting well allows the root system to provide nutrients to the root system only in a small separate area. In order to more evenly provide the root system of the plant with nutrients or to moisten the soil around the stem, it is necessary to inject water with fertilizers from at least four sides of the stem. In addition, this device does not allow for the application of liquid fertilizers or watering trees with an increased dose of water (Yul liquid fertilizers on one tree or 30-40 liters of water when watering), since its constructive design allows only dry mineral fertilizers to be applied, and the liquid is used in small doses and only for the formation in the soil of a well near the trunk of a tree and the supply of fertilizer into it from the mixing chamber.

The aim of the invention is to increase productivity by watering the entire area of the stem of the fruit tree without washing the soil with a stream of liquid.

This goal is achieved by the fact that the device for irrigating fruit trees is equipped with a metering chamber with a hinged bottom and a drain pan, and the hinged bottom is kinematically connected to the hopper guidance hoist of the pouring control system.

FIG. 1 shows a device for irrigation of fruit trees, side view; in fig. 2 - the same, top view; in fig. 3 - a metering chamber with a folding bottom and plum, a tray, with a partial cut-out.

Device for; irrigation of fruit trees, includes a tank 1 with a system 2 recirculated zirn mixing of liquid in a tank and is aggregated with a tractor 3 (a tank of spreader, liquid manure can be used as a tank with a system of recycling liquid). The pipe 4. and the other end of the pipe are connected from the pipe, the recirculation system to the dosing chamber 5. The latter is shed. hinged bottom 6, the opening and closing of which is carried out by hydrocyles, n.prpm, 7, connected to the hydraulic system of the tractor via. management Lower part of the dispensing chamber, on. in the drain; a tray 11, the pourer window of which is supplied with e, but with a fluid divider grid 12. To stop the pipeline, a valve 13 is inserted in the last inlet.

The device works as follows.

If a manure spreader is used as a tank, before filling his tank with liquid fertilizers or water, the tractor operator sets the crane 14 to a position that blocks the output of fertilizers to the spreading tool 15, fills the tank and sends the unit to the garden. When the machine is moving along the inter-fluid fluid pump 16

The pipeline of the recirculation system 2 is pumped from the front of the tank to the rear of the tank and is mixed. At the same time, a part of the fluid along the branch pipe 4 is fed into the dosing chamber and fills it.

When the probe 10 is in contact with the stem of the tree and is deflected in the opposite direction of movement of the unit, the distributor 8 of the hydraulic cylinder 7 will turn on, which will open the hinged bottom 6 and the liquid will flow in a wide stream along the chute 11. When the probe 10 comes out of contact with the trunk of a tree, it returns to its original position under the action of a spring and the folding bottom 6 closes, and pouring the liquid into the zone of the near-bar circle stops. When the probe 10 is in contact with the subsequent tree boom, the process is repeated. Filling the dosing chamber with liquid occurs during the time of moving to the next tree, and pouring out the liquid from the dosing chamber takes place during the journey of the unit along the tree circle. The rapid outflow of the liquid is due to the presence of a folding bottom in the dosing chamber, and the elimination of soil erosion is achieved due to the sufficient width of the drain pan 11 and the dissecting grid 12.

Due to the rapid outflow of fluid into the area of the barrel wheel, it is possible to increase the productivity of the unit.
