Description

DEVICE FOR VEGETABLE ENDOTHERAPY SYSTEMS INJECTIONS

5

The present utility model is a device for systemic injections of plant endotherapy, of the type used in trees, palms and / or vegetables in general, which aims to avoid multiple perforations in each new treatment, reducing the cost of it, facilitating its realization and greater sealing.

STATE OF THE TECHNIQUE

fifteen

At present, plant endotherapy or endotherapy is an alternative method of phytosanitary treatment in trees with a low environmental impact. The treatment consists of the injection of nutrients and / or systemic phytosanitary products to the sap current of the trees and / or plants so that they are translocated through the interior of the tree, and whose purpose is to control different pests, diseases or nutritional deficiencies. Thus, when the tree is evapotranspiring, it sucks the artificially contributed substances upwards along with the sap.

2O 25

Endotherapy provides advantages over traditional aerial treatments, among which the absence of fogging or atomization of chemicals in the environment as well as its safety for the health of people (citizens and applicators), not contaminating by shower runoff It affects the area of the tree. In addition, treatment can be focused, thus avoiding indiscriminate treatments and reducing the consumption of active materials, costs and risks in general.

3O 35

The uses of endotherapy extend to any type of tree with application times ranging from 30 seconds to several hours, and depend on the type of tree, the porosity of the xylem of the angiosperms: annular or diffuse, and / or the time of the year, its plant activity, or its evapotranspiration index. Making holes between 4 and 12 mm in diameter and between 50 and 400 mm deep, with a variable number of holes around the tree at different levels so as not to reduce the mechanical resistance, depending on the species, the diameter of the trunk or stipe, bearing of specimen to be treated and particularity of the pest or disease to be treated

To apply plant endotherapy injections, there are several methods, such as:

by gravity where the phytosanitary product or nutrients is injected with a manual syringe

the necessary dose in each hole, by micropressure where capsules are used

pressurized that connect to the injectors previously installed in the holes,

releasing the product from the application slowly; and finally, by pressure using

hydraulic pressure equipment that injects the plant protection product at medium or high pressure

nutrients.

DESCRIPTION OF THE INVENTION

10

The present invention describes a device for systemic endotherapy injections.

vegetable, of the type of employees in trees, palm trees and / or vegetables in general,

essentially characterized by comprising a threaded installation cannula with holes

for drainage and distribution of applicable products, reusable and waterproof thanks

to its conical head design, and the incorporation of a safety cap with gasket

O-ring together with a safety screw.

The device is characterized in turn, for being compatible with the various systems or

plant endotherapeutic injection methods because they can be coupled differently

it is necessary to drill again in each treatment, reducing the cost of it, facilitating the

treatment completion and thus reducing cryptogamic problems and infections

that can lead to the continuous realization of perforations-new wounds in each

treatment.

25

The device is installed in the trunk of the tree, where it is screwed into the hole previously

perforated, by means of a suitable tool-wrench avoiding the knocking and the wedge effect of the

tree trunk, palm grove and stems in general.

3 o

Thanks to its way of fixing on the trunk, the device prevents the entry of air, and by

therefore, the "recognition" of the wound by the tree, avoiding compartmentalization and

death of the part closest to the wounds, as a reaction to perforation and air intake

in the tree, necrosis, gels production, etc. As well as, in general, infections due to

fungi and bacteria that come into contact with the wounds of vegetables in contact with the air in

Thanks to its use, it is achieved that for specimens (for example) of palms with thick stipe, the central part can be reached, keeping a free way to incorporate the treatments to the part with more xylem activity or ascending flow of sap.

For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to restrict the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

PREFERRED EMBODIMENT OF THE INVENTION

35

A preferred embodiment of the invention is shown in the attached figures. More specifically, the device for systemic injections of endotherapy, object of

This utility model is characterized by comprising a first threaded cannula (1) for its fixation by means of threading in a hole previously made in the trunk of a tree or similar, which subsequently allows the injection of a nutrient substance and / or a phytosanitary product systemic in it.

Said cannula (1), more specifically, has a truncated conical head (1a) where a closure element (2) or cap with an O-ring and safety screw is housed, to preserve its tightness.

Additionally, when the injection of nutrients or phytosanitary products is carried out with pressure devices, an extension system of the cannula (1) or splicing element will be used, which essentially comprises an external nut (3) with a smaller metric that of the cannula (1), so that it is correctly fixed in said cannula (1), by means of a second closure element with an O-ring. Said splicing element will be variable depending on the injection system to be used by the user.

The device is made of plastic material with a grape filter, such as polyethylene or similar, not discarding other materials with similar mechanical characteristics.

The injection of the product into the cannula (1), can be done manually, by introducing it with a syringe, opening the closure element (2) and introducing it, or using low and medium pressure systems by means of the said splicing element .

Finally, it should be noted that thanks to the threading of the cannula (1), it can be unscrewed annually slightly, to avoid swallowing by the growth of the tree.
