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 an 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 channel 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 basis 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 attaching such booms, and the design of the air channel is not able to provide an air flow zone over the entire height of the vertical rod and the regulation of uniform in height air velocity, as well as different flow rates in different zones along the height of the rod in accordance with Mr. experiment.

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

the formation of a vertical air flow over the entire height of the boom with several sprays;

regulation of the total speed of the air flow, the same throughout the height of the rod and row of plant layout;

regulation of different air flow rates in individual tiers along the height of the rod and row of plant layout according to the experimental plan.

The technical result is achieved by the fact that there is a bracket for attaching a vertical rod to garden sprayers with the possibility of adjustment in height and rotation in two planes, and the air channel at the outlet has the shape of a flat vertical nozzle, throughout it is divided by horizontal partitions in transverse vertical sections into four identical sections the cross-sectional area at the outlet of the zone and at the inlet of the fan, each zone has an individually adjustable louvre shutter.

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 with a pumping station 3, driven through a cable 4, moves from a drive station including an electric motor 5, a control panel 6, a two-speed gearbox 7, a shaft 8 and a chain gear 9, to which a beam 11 is attached through a horizontal cylindrical hinge 10, supported on a wheel 12 rolling along a track 13 with artificial irregularities and having a platform 14 with a vertical mounting bracket 15 mounted thereon booms 23 with nozzles connected by a hose to the pumping station 3, fan 16, air duct 17, having the shape of a flat vertical nozzle at the outlet, all along the entire length of the horizontal partitions 18 divided into identical sections by area, and individually adjustable louvres at the fan inlet damper 19, and also located on a mesh basis on an inclined ribbed table 20 with a block of graduated cylinders 21, a model of a row of cultivated plants 22.

The proposed stand works as follows. The test vertical rod is installed in the mounting bracket in the position specified by the test conditions.

The working fluid from the pumping station under various pressures (in accordance with the experimental plan) is supplied to the sprayers of the vertical rod and applied when the cart moves at a given speed on the model of a row of cultivated plants. The set air flow rate in the zones of the liquid spray plumes on different tiers of the plant model is regulated in accordance with the experimental plan by the louvre shutters at the air channel inlet and is controlled by an anemometer in the cluster zone of the plant model.

The dispersion of the spray and the distribution of droplets inside the plant layout is fixed using registration cards hung on them.
