Description

The invention relates to agricultural machinery, and in particular to technical means for chemical protection of strawberry plants, and can be used in the chemical treatment of other low-growing crops.

Known sprayer for strawberry ONZ-600 (http://elibrary.ru/item.asp?id=18095411, http://vinogradsadtehnika.ru/opriskivatel-navesnoi-onz-60html), which has a tank and side rods with sprayers .

A disadvantage of the known device is that it is trailed, therefore, the harmful effects of chemicals on the operator-driver cannot be ruled out and does not have a protective casing.

The closest in technical essence to the claimed device is a field robot in the unit with a sprayer (http://www.technologyreview.com/news/408225/robotic-farmer/), consisting of a frame, steered wheels, at least two of which equipped with electric motors for the sprayer drive, a control and navigation system with instrumentation, a power system, a spray system containing a container for working solution and boom.

A disadvantage of the known device is that it only serves to control undersized weeds and does not have the ability to automatically adapt to the height of plants, i.e. change the height of the rod in automatic mode. Also, the sprayer does not have protective covers to protect cultivated plants from chemicals, and the nozzles are located only on top.

The technical task of the invention is to increase the safety, quality and efficiency of the chemical treatment of strawberry plantations, reducing the number of treatments.

The stated technical problem is achieved in that a self-propelled spraying robot for processing strawberry plants and other low-growing crops, including a frame, steered wheels, at least two of which are equipped with electric motors, a control and navigation system with instrumentation, a power system, the spraying system containing the container for the working solution and the rod, according to the invention, the rod is equipped with universal sensors for the height and presence of plants, as well as an electric cylinder, made nnym with adjustable height bar arrangement depending on the height of the crop plants and with four sprayer units, each unit performing a three nozzles arranged in a protective casing.

Improving safety and minimizing the harmful effects of chemicals on humans is achieved by eliminating the direct involvement of the driver in the process. The utility model is illustrated by drawings.

In FIG. 1 schematically shows a self-propelled robot sprayer for processing strawberry plants, top view; in FIG. 2 - the same rear view; and in FIG. 3 is the same side view.

Self-propelled spraying robot for processing strawberry plants and other low-growing crops consists of a frame 1, wheels 2, at least two of which contain electric motors 3 for driving the sprayer, and the front wheels 2 are controllable, control and navigation systems 4 with control and measurement devices, power systems 5 and spraying systems. The spraying system contains a container 6 for the working solution, a rod 7, universal sensors 8 for the height and presence of plants and an electric cylinder 9 for adjusting the height. At least four spraying units are located on the booms 7. Each assembly 10 contains three automatic nozzles 11 and a protective casing 12. The spraying robot has an electric pump 13, a washing tank 14, a mixer 15, a differential dispenser 16, an onboard computer 17.

The casing 12 is made, for example, plastic, in the form of a semicircle, in which are placed three automatically controlled nozzles 11 located in an arc relative to each other at an angle of 90 °.

The boom 7 with sprayers has the ability to automatically adapt to the height of the treated plants, by raising and lowering it with an electric cylinder 9 (actuator).

The device operates as follows.

Before the start of the production process, they draw up diagrams of the field boundaries and impassable places, program the sequence of turns of the sprayer.

Then the sprayer drives into the rows of strawberries, automatically adjusts the height of the rod 7 to the height of the plants by means of sensors 8 and an electric cylinder 9. Continuing the movement, the spraying nodes 10 treat the plants with chemicals. Due to the fact that one nozzle 11 is located above the bush, and the other two to the left and right of the bush, it is possible to evenly distribute the chemicals throughout the crown of the plant, including applying the drug on the back of the leaves, while the protective cover 12 prevents the drug from entering the zone spraying on other plants.

If there are gaps in the row of plants, then, according to the signals from sensor 8, the flow of chemicals stops and resumes only where there are plants.

The operator has the opportunity to observe the spraying process through video cameras and, if necessary, can adjust the operation of the self-propelled spraying robot using the remote control. For remote control of the sprayer sections, the device has an on-board computer 17.

After the entire solution is consumed in the tank 6 of the device, the robot sprayer is sent for refueling. After refueling, the workflow continues.

The use of the inventive sprayer will provide increased safety of the chemical treatment of plants, will improve the quality of processing plants, as a result, the number of treatments can be reduced, which saves labor costs by 15-25%.
