Description

The invention relates to agricultural engineering, in particular to technical means for processing plants.

A machine is known for forming wells in the soil for planting grape stems (Patent for invention A.S. SU 117049, 45f, 4/09, 1958), including several hydraulic drills in the form of pipes vertically immersed in the soil with nozzles for water outlet, mounted in front of the tractor on a horizontal pipe, moved in the vertical direction by a hinged mechanism such as a paired four-bar link, as well as the use of hydraulic drills with a check valve equipped with a rod with a support heel, which ensures that the valve opens when the heel comes into contact with the soil.

Its disadvantages include the inability to use this machine when applying working fluid to the center of the root zone of young orchards and vineyards.

The closest in technical essence to the declared injector module is an unit for introducing liquids into the soil (Patent for invention SU 927164, IPC A01C 23/02, 1977). Includes a container mounted on the frame and a hinged device for injection, consisting of a carriage with a block of injecting working elements, a mechanism for regulating their position, made in the form of a rocker with a groove, a hydraulic switch mounted on the rocker, a valve and a control mechanism, made in the form of a single-acting hydraulic cylinder . In the groove of the rocker there is a roller connected to the injection working parts, and above the groove in the rocker there are holes for installing a hydraulic switch.

The disadvantage of the device is the fixed distance between the injecting working bodies, which limits the range of use of this unit for various technologies for planting orchards and vineyards.

The technical objective of the proposed invention is to increase productivity by introducing working fluid directly into the root zone of young orchards and vineyards in an automated manner.

The technical result is achieved by the fact that an automated injector module containing a frame, a container with a liquid compressor mounted on it and a hinged injection device, according to the invention , it is equipped with an air compressor with a receiver, a pneumatic cylinder, an additional liquid compressor and a container for working fluid, the containers are connected with an injector installed with the ability to adjust the angle of inclination to the supporting surface and made in the form of a frame connected to two pairs of guides, the upper pair of guides is rigidly fixed to the frame and connected to the lower pair by two carriages and two bearings with the ability to slide along the upper pair, while the bearings rigidly fixed in the lower part of the frame, in the lower part of the lower pair of guides a double-circuit injector rod with three inputs for supplying the working mixture and a tip is fixed, a pneumatic cylinder is installed in the cavity of the frame and is rigidly connected to it in the upper part, and in the lower part with the injector rod bracket, the first the contour of the injector rod is designed to introduce water or gel, the second is for air.

The invention is illustrated by drawings.

In fig. 1 - robotic pneumatic injector (side view); in fig. 2 - robotic pneumatic injector (front view);

The automated injector module contains a frame 1, containers 2 and 3 with working fluid mounted on it, liquid compressors 4 and 5, a hinged injection device 6, an air compressor with a receiver 7, a pneumatic cylinder 8. Capacities 2 and 3 are connected to an injector 6 installed with the ability to adjust the angle of inclination to the supporting surface and made in the form of a frame 9 connected to two pairs of guides 10 and 11. The upper pair of guides 10 is rigidly fixed to the frame 9 and connected to the lower pair 11 by two carriages 12 and two bearings 13 with the ability to slide along the upper pair 10. Bearings 13 are rigidly fixed in the lower part of the frame 9. In the lower part of the lower pair of guides 11, a double-circuit injector rod 14 with three inputs for supplying the working mixture is fixed. The pneumatic cylinder 8 is installed in the cavity of the frame 9 and is rigidly connected to it in the upper part, and in the lower part - to the bracket 15 of the injector rod 14. The first contour of the injector rod 14 is intended for introducing water 16 or hydrogel 17, and the second for supplying air 18.

The automated injector module works as follows.

Before starting work, the automated injector module is installed on a self-propelled cart or tractor (not shown in the figure).

When a self-propelled trolley or tractor (not shown in the figure) stops in the aisle of a garden or vineyard, the automated injector module is located directly opposite the trunk of the apple or grape tree. In automatic or manual mode, a command is sent to the controller (not indicated in the figure) to start a cycle of operations.

Next, the controller sends a command to the air distributor (not shown in the figure) to open its section to supply air into the piston cavity of the pneumatic cylinder 8. The lower part of the injector 14 is deepened into the root zone of the apple or grape trunk. In this case, the working fluid is supplied into the cavity of the injector rod 14 and then through the tip (not shown in the figure) into the soil. Due to this, the resistance to penetration of the tip into the soil is reduced.

A limit switch installed on the guide 11 (not shown in the figure) sends a signal to the controller that the injector rod 14 is completely buried in the soil. The controller sends a signal to compressors 4 and 7 or 5 and 7 to supply the working mixture by turning on the corresponding compressor 4 or 5, depending on the type of liquid supplied to the root zone of the trunks of the garden or vineyard. Liquid supply counters installed in the line (not shown in the figure) signal the controller about the amount of working fluid supplied, and it, in turn, gives a command to compressors 4 or 5 to turn them off and close the working fluid supply valves. Then the controller gives a command to the distributor (not shown in the figure) to supply air under pressure into the rod cavity of the pneumatic cylinder 8.

After completing the supply of working fluid and air under pressure to the root zone of the plant, the controller issues a command to stop supplying working fluid and air, and to remove the injector from the soil. Then the controller of the injective type module sends a signal to complete the cycle of its operations and the controller gives a command to its actuators to begin movement. The process is repeated.

The automated injector module will allow you to apply working fluid directly to the root zone of the trunks of a young orchard and vineyard, by automating the application process and applying the working fluid more accurately and in doses.

The use of an automated injector module will increase productivity and reduce the consumption of working fluid.
