Description

The proposed utility model relates to the field of agricultural engineering, in particular to methods and devices for testing the working bodies of sprayers.

Known stand [N. Ramon, B. Missotten, J. De Baerdemaeker. Spray Boom Motions and Spray Distribution: Part 2, Experimental Validation of the Mathematical Relation and Simulation Results // J. agric. Engng Res., 1997, Vol. 66, No. 1. - P. 31-39.], Designed to study the dispersion of the spray and the uniformity of the deposition of liquid by the working bodies of the sprayers in motion, consisting of a stationary inclined table, divided by ribs into channels, 0.05 m wide; block measuring cylinders for collecting fluid from each channel; a pump installation that provides fluid to the boom under the necessary pressure and a movable trolley for moving the test spraying body along the inclined table. This design allows you to test the spraying working body of the sprayer in motion and to determine the quantitative and qualitative characteristics of liquid deposition over the area.

The disadvantage of this stand is that it does not allow you to examine the working body in the form of a support rod, does not allow you to take into account the influence of wind speed and vibrations of the working body under the influence of the relief, does not allow creating conditions for the penetration of drops into a row of cultivated plants and fixing the drop composition of the liquid deposited in the protective zone of cultivated plants.

The closest analogue to the claimed is a stand for testing the working bodies of the sprayers [Copyright certificate RU patent No. 74764, IPC class. A01m 7/00, 2006], consisting of a fixed inclined table, divided by ribs into channels, 0.05 m wide; block measuring cylinders for collecting fluid from each channel, a pumping unit that provides fluid to the rod under the necessary pressure and rolls along the rails of the cart to move the tested spraying body along the inclined table, equipped with a drive station that includes an electric motor, a control panel, a two-speed gearbox, shaft and chain gear; a fan, a rotary air duct are mounted on the movable trolley, and a spraying working element is attached pivotally, with the possibility of rotation in two planes, with a support mechanism that rolls next to the rails along a special track with artificial irregularities, and a row layout is installed on the ribbed table on a mesh base cultivated plants.

The disadvantage of this utility model is that the design is not suitable for testing the working bodies of sprayers in the form of vertical booms with several sprays, for example, arched and L-shaped.

- there is no adapted mechanism for fastening vertical rods with the ability to adjust the height and installation angles to the direction of movement;

- the placement of the fan and the air channel on the trolley, and the working body with the wheel bearing rolling on a track with artificial bumps, do not allow the installation and fixing of different directions of the air flow relative to the working body according to the experimental plan;

- there is no possibility of creating and depositing on the registration cards in the cluster zone of the mock-up of plants of differently colored drops, to study the interaction of droplet torches of neighboring sprayers in the area of their overlap in order to optimize the placement of sprayers on the rod in height and installation angles to the direction of movement, according to the experimental plan.

The technical result of this utility model is the emergence of the following new significant features:

- installation and fixing of different directions of air flow relative to the working body according to the plan of the experiment;

- the formation in the vertical rod working body and the spray zone of the layout of the multi-colored spray torches;

- the possibility of creating and depositing on the registration cards in the cluster zone of the mock-up of plants of differently colored droplets, to study the interaction of droplet torches of neighboring sprayers in the zone of their overlap in order to optimize the placement of sprayers on the rod in height and installation angles to the direction of movement, according to the experimental plan.

The technical result is achieved due to the fact that two containers with liquid of different colors, two pumps connected by hoses to the corresponding capacity and with atomizers of the working body in the form of a vertical rod are installed on the trolley so that the liquid colors of neighboring nozzles do not coincide, and the fan is rotary the air channel and the mounting bracket of the working body are placed on a platform mounted on a beam attached to the carriage through a horizontal cylindrical hinge and supported by a wheel rolling on track with humps.

The specified set of essential features ensures the appearance of the inventive stand for testing the working bodies of sprayers with new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty."

In FIG. 1 is a schematic diagram of a stand explaining its operation, a top view, in FIG. 2 - the same, view A.

The test bench for the working bodies of sprayers consists of a rail track 1, along which a trolley 2 moves, driven through a cable 3 from a drive station including an electric motor 4, a control panel 5, a two-speed gearbox 6, a shaft 7 and a chain gear 8, a fixed inclined table 9, divided by ribs into channels, a block of graduated cylinders 10 for collecting liquid from each channel, a model of a row of cultivated plants 11, installed on a mesh basis, with registration cards hung on it, tracks with artificial bumps the rests 12 mounted on the trolley of two containers 13, 14 with liquid of different colors and two pumps 15, 16 connected by hoses 17 and 18 with the corresponding capacity and with sprayers 19 of the attached test body 20 in the form of a vertical rod in such a way that the colors of the neighboring fluid the nozzles do not match, the fan 21, the rotary air channel 22 and the bracket 23 for fastening the working body 20 located on the platform 24, mounted on the beam 25, attached to the carriage 2 through a horizontal cylindrical hinge 26 and supported wheel 27 which rolls along a track with humps 12.

The proposed stand works as follows.

The trolley 2 and the articulated beam 25 attached to it move along the layout of a row of cultivated plants 11 along the track 1 at different speeds reported by the drive station according to the experimental design.

At the same time, the beam 25 and the fan 21 mounted on it with a rotary air channel 22 and the bracket 23 with the tested working body 20 fixed therein also receive vertical vibrations due to rolling of the support wheel 27 along track 12 with irregularities established, according to the experimental plan.

The working fluid of different colors by pumps 15 and 16 from the tanks 13 and 14 under various pressures, in accordance with the experimental plan, is supplied to the atomizers 19 of the attached test working body 20, sprayed and partially deposited on the registration cards in the form of colored drops.

Known cards using known methods analyze the dispersion of the spray, the density and uniformity of the droplet coating in the overlapping area of the spray nozzles at their different locations on the boom, according to the experimental plan.
