Description

Application area

The utility model relates to the field of forestry and gardening and is intended primarily for the "point" destruction or treatment of woody vegetation in urban areas, parks, gardens, arboretums, where sanitary standards forbid the spraying or application of herbicide solutions to the soil.

State of the art

The problem of "point" destruction of trees is especially acute in urban conditions, when the selected tree is located near urban infrastructures, where external use of active solutions is prohibited by sanitary standards. The task of destroying trees or shrubs is complicated by the fact that a simple mechanical sawing of trunks does not exclude vegetative pneumatic and / or root renewal. To solve this problem, mechanical injectors in the form of a syringe or ax are common, which inject the active solution into the tree trunk. For example, patent RU 2208313 for an Axial Injector is known, comprising a hollow butt fixed to a handle, a container for a chemical solution, a blade with holes, channels with inlet and outlet valves and a metering chamber with a spring-loaded piston, characterized in that it is equipped with an additional piston with a rod mounted in the cavity of the butt with the ability to move through the adjusting nut, and the metering chamber is formed by these pistons. The disadvantage of this and other devices is the difficulty of optimizing the amount of solution used during the injection, which leads to the need for repeated or even repeated carrying out this event, or an excessive increase in the flow rate of the solution.

Technical solutions related to the destruction of trees with ensuring self-regulation of the amount of expenditure of the active substance is unknown. Also, technical solutions related to universal ones and allowing to use them both for destruction and for treating trees are not known.

Technical result: the device allows, without human control, the destruction of trees with the provision of self-regulation of the amount of expenditure of the active substance, the device is universal - it is applicable both for the destruction and treatment of trees.

Brief Description of the Drawings

Figure 1 shows a structural diagram of the device, where 1 is a tree trunk, 2 is a hole drilled in the trunk, 3 is a hollow needle, 4 is a hose, 5 is a tank, 6 is a tree branch, 7 is a fastening device to the tree (rope), 8 - crane.

Utility Model Implementation

The fundamental novelty of the solution lies in the fact that the proposed device automatically ceases to work after the death of the plant, providing 100% destruction of undesirable woody vegetation in various growing conditions.

The claimed technical result is achieved due to the fact that the device for the destruction or treatment of trees and shrubs containing a reservoir with a solution for injection, characterized in that it contains a hollow needle connected to the reservoir so that the reservoir is higher than the needle in height. The connection of the needle and the reservoir can be done through a hose. At the junction of the needle and the reservoir, a crane may be provided. The reservoir may be made of solid material, and the conductive system is configured to function according to the principle of a medical dropper.

The essence of the device and the principle of operation

A device for the destruction or treatment of trees and shrubs (see Figure 1), consisting of a hollow needle (2) and a reservoir (5) connected to it, for example, by means of a hose (4), is attached to a tree or shrub, for example, by hanging by the fastening device (in this case, the rope) (7) of the reservoir by the branch (6).

As the reservoir (5), any container that can be fixed, for example, a conventional heating pad (see Figure 1), can be used. The reservoir (5) can also be made of solid material, such as glass, and the conductive system (4) in the form of tubes of a medical dropper. This allows you to track the degree and speed of death.

or plant recovery for scientific observation.

Then, a hole (2) is drilled in the barrel (1) with a drill, into which the hollow needle (3) is inserted. It is preferable, for the convenience of regulating the flow of the solution, to carry out a crane (8 ) for the free flow of solution from the reservoir into the plant.

Moreover, due to the fact that the reservoir (5) is higher than the needle (3), the resulting vacuum in the device (due to loss of fluid) is automatically compensated and compared with atmospheric pressure due to the (identical, corresponding) equivalent decrease in the volume of the reservoir (5) .

To destroy a tree or shrub, a standard herbicide solution is used (for example, Roundup or Arsenal). In this case, as the solution is absorbed, the plant dies, and the absorption rate decreases to zero with a complete lethal outcome.

In other words, the solution is consumed exactly as much as is necessary for the complete death of the plant.

For the treatment of a tree or shrub, various formulations are used with top dressing or growth stimulants. At the same time, the solution is absorbed by the plant until the container is completely empty (5).

The advantage of the claimed device lies in its maximum possible environmental friendliness, economy and the possibility of use during the entire growing season.
