Description

The utility model relates to agricultural engineering, in particular, to devices for applying pesticides with slot and turbopen sprayers.

A device [1] is known for reducing the drift of pesticides, which is a smooth pipe mounted on the sprayer boom. During the movement of the machine, this device presses the stalks of grain crops and, thereby, creates a free space in the crops into which a solution of the working fluid is introduced using flat-blasting sprayers. In this case, the sprayer boom extends at a distance of about 20 cm below the upper edge of the crop. This device significantly reduces the drift of drops of the working fluid.

The disadvantage of this device is the rigid fastening of the smooth pipe to the sprayer boom, which does not protect the device for introducing pesticides from breakdowns when meeting with a horizontal or vertical obstacle.

A device [2] is known for introducing pesticides in both continuous and tape methods with slot and turbopen sprayers. The device comprises means for supplying a working fluid under pressure,

a distribution pipe (manifold) with flexible expansion hoses, an atomizer assembly with a protective shield fixed in the sleeve, bracket and on the metal pipe of the sprayer truss. The sprayers are mounted with the possibility of rotation in the horizontal plane at a given fixed angle to the axis of the row or to the axis of the rod from 0 to 90 °. The presence of a protective screen with a double cover in the device allows you to catch small droplets with a diameter of less than 70 microns and reduce the drift of the working fluid.

A disadvantage of the known device is that drops captured by the protective screen of less than 70 microns are discharged outside the row of row crops, increasing the environmental load, as well as the inability to use a double-protective protective screen for continuous application of pesticides.

The aim of the proposed technical solution is to improve the quality of processing plants, reducing environmental stress by reducing drift and saving pesticides.

The goal is achieved by installing means for tilting cereal plants in the form of an oval stainless steel tube-tank on the sprayer bar with feeding and suction hoses and spray nozzles with protective screens with the possibility of their rotation in a horizontal plane at a given fixed angle to the row axis or axis rods from 0 to 90 °. The oval tube-container is installed on the sprayer boom on horizontal hinges parallel to the axis of the boom, using flexible elastic ropes passed inside the compression springs and connected to the oval-tube-container and attachment points with the sprayer boom with the possibility of adjusting the spring elasticity. The stops are rigid and elastic, mounted on the pipe of the sprayer truss, limit the deviation of the oval tube-container in the longitudinally vertical plane. Each protective screen through the gutter is elastic

by feeding sleeves it is connected to an oval tube-tank, and a tube-tank by a suction hose with a three-way valve - to the suction line of the sprayer.

Figure 1 shows the proposed device (side view in section) and the connection diagram to the suction line of the sprayer, figure 2 - the proposed device (rear view) and the connection diagram to the suction line of the sprayer.

The proposed device contains means for supplying a working fluid under pressure, a distribution pipe with flexible expansion hoses, spray nozzles with protective shields fixed in the sleeve, bracket and on the pipe of the sprayer truss, an oval tube-container with fittings and elastic sleeves connecting it to the protective gutters screens, and a suction sleeve using a three-way valve - with the suction line of the sprayer, the elastic suspension of the pipe-container on the sprayer boom containing elastic ropes, etc. fired inside the compression springs, pipe-fixing tank with the possibility of regulation of elastic springs nodes, and stops hard and elastic, which limit the deflection of the pipe-in container longitudinal-vertical plane. The elastic stops with rollers limit the axial displacement of the tank tube. Ropes, rollers, cylindrical bushings provide longitudinal stability of compression springs.

The tool for tilting the plants and collecting the working fluid consists of an oval tube-container 1 made of stainless steel with fittings welded along its entire length, under the feeding sleeves 2 and the fitting under the suction sleeve 3, two cylindrical bushings 4 with flanges and grooves along the axes with holes under the finger 5, welded to the pipe-container 1 at the smaller diameter of the oval at the ends for attaching the lower ends of the ropes 6, stocked for loops and for installing compression springs 7. The removable suspension unit of the pipe-container 1 consists of two steel strips 8 welded to

the lower pipe of the sprayer farm with axial openings between which there are two bearing steel plates 9 with axial openings, and a cylindrical sleeve 10 welded to the plates 9 with a flange and a single-axis groove for laying the upper end of the rope 6, stocked for an elongated free loop. Between themselves, parts 8, 9 and the loop of the rope 6 are connected by a bolt 11, which plays the role of an axis. The tensioning device 12 is made in the form of a stud with a thread from one end passing through vertical holes in the pipe of the sprayer farm and bent under the hook, the second end passing into the upper elongated loop of the rope 6. The plate 13, rigidly fixed to the pipe of the sprayer farm, is used to limit suspension deviations. Spring leaf 14, mounted on the lower pipe of the sprayer truss, one end with a stepladder 15 and rollers 16 mounted on the lower end of the spring leaf 14, mounted on an axis with a bolt 17 with washers and a nut, which ensures that the tank tube returns to its original position after its deflection when meeting an obstacle, as well as limiting the axial displacement of the pipe-container 1. The bushings 4, 10 and the rope 6 provide longitudinal stability of the compression springs 7.

The proposed device works with continuous spraying as follows: a rod with an oval tube-capacity 1 and nozzles is installed so that the longitudinal axis of the nozzle slit relative to the axis of the rod is rotated 5-7 ° and is located at a distance of about 20 cm above the upper edge of the culture, and capacity 1 - at a distance of 20-25 cm above the soil surface. The spray shield is 1-3 cm above the top of the crop. During the movement of the MTA, the oval tube-container 1 tilts the stalks of grain crops down and creates a free space in the crops into which a solution of the working fluid is introduced using slotted sprayers. Such a device significantly reduces the drift of droplets of the working fluid by the wind. In addition, drops of working fluid with a diameter of less than 70 microns, accumulating on

the inner porous surface of the screen, drain into the gutter and accumulate along the elastic supply hoses 2 in an oval tube-container 1. Before the next refueling of the main tank of the sprayer, the working fluid from the pipe-tank 1 is pumped into the main tank of the sprayer through a suction sleeve 3. A three-way valve self-priming position, elastic sleeves 2 at suction, compressing, block air access to the suction line. After suction from the pipe-container 1 of the working fluid, the position of the three-way valve is set to its original position.

When encountering obstacles, the means for tilting the plants and collecting the working fluid on horizontal hinges 11 can deviate in the direction opposite to the movement of the MTA and return to their original position in the longitudinal-vertical plane due to the elasticity of the leaf springs 14. Change the height of the pipe-container 1 above the field surface due to compression of the springs 7. When meeting a one-sided load, the pipe-container 1 can be deflected on one side both on a horizontal hinge in the form of a bolt 11 and on a compression spring 7. Such a suspension of pipes s-tanks 1 allows you to avoid damage to the sprayer during operation of the MTA. The connection of the oval tube-container 1 with the trough of the protective screen with elastic feeding sleeves 2 avoids the installation of taps. Collecting the working fluid in the form of droplets with a diameter of less than 70 μm in the tank tube 1 with its subsequent suction for reuse with the pump and a three-way sprayer valve and suction sleeve 3 allows to reduce the flow of working fluid, as well as reduce the environmental load. When applying pesticides by tape, the tilt agent is removed.

The proposed device for applying pesticides in a continuous way with slotted sprayers can significantly reduce the drift of the droplets of the working fluid by the wind, improve the quality of their application, save pesticides, reduce the environmental burden on the environment, and introduce pesticides with greater winds.
