Description

The invention relates to agriculture, namely to the protection of plants, and can be used on state farms and collective farms to control pests and to control pests and diseases of agricultural crops,

A device is known comprising a vehicle, a chassis, a fluid container, a pump with a metering system, an arcuate rod with sprays located around the perimeter, and a spherical shape with a platform inside the rod that adjusts in height.

However, the device has the following disadvantages: it does not allow a low-volume spraying of bushes; Significant losses of used fluid entering the interstitial space; the vertical arrangement of the spherical atomizer inside the rod leads to great damage to plants.

The closest solution is a device comprising a vehicle, a chassis, a pressure pump, slotted air diffusers and atomizers located on the inner surface of the protective casing.

However, this device has the following disadvantages: the possibility of damage to the bushes during their processing, irretrievable loss of fluid due to its partial deposition on the inner surfaces of the casing, and then draining to the ground.

The aim of the invention is to increase the efficiency of processing plants and reduce fluid flow.

This is achieved by the fact that in a device containing a vehicle, a chassis, a discharge pump, a compressed air source, air slot diffusers and sprayers located on the inner surface of the protective casing, the protective casing is made in the form of a truncated cone in longitudinal section of two articulated interconnected in the upper part of the halves, which are equipped with spring-loaded brushes along the lower edge, while the nozzles are located evenly around the perimeter of the front end part, along the lower edges and the articulated soy the protective casing, and air diffusers and sprayers are installed on the lower edges of the casing alternately and at an acute angle to the inner surface of the casing.

Figure 1 shows a diagram of a General view of the device; figure 2 is a diagram of one of the semi-surfaces of the protective casing; in Fig.3 is a view along arrow A in Fig.2.

The device comprises a vehicle 1, a chassis 2, which is a carrier for mounting the pressure pump 3. and a source for supplying compressed air 4,

5 providing the supply of liquid and air under pressure to the slotted air diffusers 5 and the liquid atomizers 6 mounted on the inner surface of the protective casing, made in the form of 0 two parts 7, pivotally connected to each other in the upper part and forming a truncated cone in longitudinal section, and in the lower part of the casing, spring-loaded brushes 8 are installed perpendicular to the 5 direction of plant growth (Fig. 2). Liquid sprayers 6 are located evenly around the perimeter of the front end part, along the lower edges and the hinge of the protective casing, and air diffusers 5 are mounted alternately along the lower edges of the casing with sprayers 6 and at an acute angle to the inner surface of the casing.

The device operates as follows.

When the vehicle 1 is moving, the plants freely enter under the protective cover, as its front part in cross section has a large diameter. Over plants

A closed volume is formed at the length of the casing. Sprayers 6 supply fluid to the plants around the entire perimeter of the end portion of the protective casing. Slit-shaped diffusers 5 supply compressed air at an acute angle to

5 of the inner surface of the casing and the direction of movement. Sprayers 6 create the necessary concentration of liquid in a closed volume, due to which the plants are subject to a certain period of time

0 contact treatment with sprayed liquid while maintaining its high concentration in this volume.

Using the proposed solution reduces the flow rate of the applied fluid to thirty percent, eliminates the ingress of fluid onto the inter-surface, and increases the efficiency of the device by treating plants in a closed volume.
