The invention relates to agricultural machinery, in particular to machines for controlling diseases, pests of weeds and weeds.

Plant sprayers are known which include sawing organs oriented transverse to the direction of their movement and casings for trapping active liquid.

The disadvantages of the known devices are increased consumption of active fluid and, consequently, pollution of the medium.

The closest set of features to the proposed technical solution is a plant sprayer containing sawing organs oriented transversely to the direction of its movement and a cone-shaped casing for trapping active liquid located opposite to the sawing organs and connected to the suction pipe.

A disadvantage of the known plant sprayer is the increased consumption of active liquid and, consequently, environmental pollution.

These drawbacks are explained by the fact. that the spraying and deposition of the active liquid takes place due to the use of an excess air flow, it is necessary to use an increased dose of the active liquid, and a significant part of the aerosol is released into the environment, polluting it.

The problem solved by the invention is to reduce the consumption of active liquid and reduce environmental pollution, including by combined application of the active liquid by spraying and wetting.

The problem is solved in that in a plant sprayer containing sawing organs oriented transversely to the direction of its movement and a cone-shaped casing for trapping active liquid, located opposite to the sawing organs and connected to the suction pipe, the cone-shaped casing with bells are oriented forward at an angle to the direction of movement and have gutters a channel made along the lower inner surface of the bell of the conical casing.

In addition, to solve the problem of increasing the efficiency of the combined application of the active liquid, the inner surface of the bell of the conical casing has a coating made of absorbent material.

The oppositional arrangement of the spraying organs and casings allows a portion of the active liquid that has not settled on the leaves of the plants to be directed onto the inner surface of the cone-shaped bell mouths. The connection of the narrow ends of the conical casings with the suction pipe allows you to collect unused active liquid in a special container and

direct it to recirculation.

Orientation of the conical shells with the flares forward at an angle to the direction of movement is necessary both for collecting the active fluid and for covering the flare during contact interaction. This allows you to change the position of the plant during operation, apply the active liquid by wetting, and thereby increase the efficiency of the process

0 combined application of active liquid.

A groove channel formed along the lower inner surface of the bell of the cone-shaped casing allows

5 to increase the reliability of collecting unused active fluid and use it to wet the inner surface of the cone-shaped housings, or direct the fluid to recirculation.

0 Improving the efficiency of the combined application of the active liquid is achieved by coating the inner surface of the cone-shaped shells with a layer of absorbent material.

5 Moreover, plant leaves touching the surface of the hygroscopic material layer are wetted with an active solution that did not get onto these leaves when the spray liquid applied directly, and thus, the active liquid without recirculation is involved in use.

In FIG. 1 shows a plant sprayer, rear view; figure 2 is the same, view sver5 xy; Fig. 3 is a cone-shaped casing, an embodiment with a grooved channel, front view; Fig. 4 is a cone-shaped casing, an embodiment with a coating of a layer of absorbent material, front view.

The plant sprayer includes spraying bodies 1 oriented transversely to the direction of movement D and cone-shaped casings 2 for trapping active liquid. The spraying bodies 1 and the casings 2 are located opposite, in the conical casings 2 the bells are oriented forward at an angle a to the direction of movement. The narrow ends of the casings 2 are connected to the suction pipe 3.

The sockets of the conical shells 2 along part of their lower and inner surface have a grooved channel 4 connected by an additional pipe 5 to the suction pipe 3.

In another embodiment, the inner surface of the sockets of the conical shells 2 is coated with a layer -6 of absorbent material.

In operation, the plant sprayer moves around the field so that rows of agricultural plants pass in the space between the sawing organs 1. directed transversely to the direction of movement D and the cone-shaped casings 2 to trap the active liquid. Due to the described orientation of the bodies 1 and casings 2, the spray of the active liquid is directed from the bottom up, and the direct liquid stream moistens the most susceptible, stomata-covered surface of the leaves of the plants. Part of the active fluid as a result of swirling flow covers the upper surface of the leaves of the plants, and another part of the active fluid that does not fall on the leaves is absorbed through the sockets of the conical casings 2. The largest drops of the active fluid settle on the inner surface of the conical casings 2, drain to the lower part of the casing 2 and accumulate in the gutter channel 4, from where, through an additional pipe 5, they are sucked into the main channel of the pipe 3. Through the suction pipe 3, the unused active liquid collected in a special container and sent for recycling. Thank you

orientation of the sockets of the cone-shaped casings 2 forward at an angle a to the direction of movement D, the inner surface of the sockets touches the plants. At the same time, the film of active liquid on the inner surface of the sockets of the cone-shaped casings 2 moistens the surface of the leaves of the plants, the opposite side of the direct spraying, and the plants themselves change

their position and are more comprehensively coated with active liquid.

In another embodiment of the conical casing 2, the efficiency of the combined application of the active liquid is increased. This is achieved by coating the inner surface of the sockets of the conical casings 2 with a layer 6 of absorbent material, which

retains and evenly distributes active liquid. The leaves of plants touching the surface of layer 6 of the hygroscopic material during the movement of the sprayer are wetted with an active solution that did not get on these leaves during direct application of liquid by spraying. Thus, an active liquid without recirculation is involved in use.

The proposed device allows to increase the efficiency of the application of drugs and thereby reduce the rate of flow of the active liquid and the degree of environmental pollution.
