Description

Equipment for injecting liquids into trees or palm trees.

Technical sector

The present invention is related to the therapeutic treatment of trees or palms known as endotherapy, proposing a therapeutic liquid injection equipment in the trunks of trees or stipes of palm trees, which allows the application of endotherapy in a simple and effective way, with a constant pressure and a controlled amount of liquid.

State of the art

Various therapeutic treatments for trees or palm trees are known, which consist of the application of therapeutic products so that the plant absorbs them in different ways, for example through the leaves by applying powdered products on the plant, or through the roots by applying products scattered on the ground or mixed with irrigation water.

The application of this type of treatments has the disadvantage that it is poorly controlled, the effectiveness being very dependent on weather conditions, such as rain or wind, which can dissipate products without plants absorbing them; and also the application can affect people, animals or plants in the environment of the treated plants, as well as the environment in the form of pollution, this being, for example, very important in parks, where children can come into contact with the Earth and plant leaves.

The treatment by endotherapy is also known, which consists of the injection of therapeutic liquids in the trunk of the trees or stipe of the palm trees, so that said therapeutic liquids are absorbed through the plant tissues, with which an application can be made in a much more controlled way, and also the influence of environmental conditions on the application is avoided, as well as the affectation to the environment and to the people, animals or plants around the treated trees or palms, since the therapeutic product is introduced directly inside the trunks of trees or stipes of palm trees, so there is no dispersion in the environment. A conventional method of applying endotherapy in trees or palm trees consists in introducing the therapeutic liquid under pressure into a hole made in the trunk of the tree or stipe of the palm tree, obtaining the hole with a sealing material and then introducing the liquid , which allows the tree to absorb the therapeutic fluid through its tissues.

The treatment thus is effective to avoid the dispersion of the therapeutic liquid that is applied, but to obtain an optimal result and avoid possible adverse effects on the plants, it is important to control the amount of the therapeutic liquid that is applied and the pressure of the application, having to adapting these parameters according to the type and size of the plants to which the treatment is applied, since with an insufficient amount of therapeutic liquid and / or an application pressure too low, the treatment may be ineffective, while with excessive amount of therapeutic liquid and / or application pressure too high, plant tissues may be damaged.

Different types of equipment are known to apply endotherapy, there are manual equipment that is simple and economical, and also automated equipment that is more complex and expensive. However, with the equipment known in this regard, both the pressure of the application and the amount of therapeutic product that is applied depend fundamentally on the criteria and experience of the operator who manages the equipment, so there is a risk that the applications of treatment are not carried out correctly depending on the characteristics of the application plants.

Object of the invention

In accordance with the present invention, a device for injecting liquids into tree trunks or stipes of palm trees is proposed for the purpose of applying endotherapy treatments, allowing the injection of therapeutic liquid in a controlled amount and at a constant pressure.

This equipment object of the invention consists of a device comprising a pumping cylinder connected to a container containing therapeutic liquid, said pumping cylinder leaving a tube that incorporates an injection needle at the end, while inside the cylinder A piston is housed in a pump which is associated with a rod related to a retraction motor and with a pushing mechanism, the assembly of a control command that allows the retraction and forward movement of said piston of the pump cylinder to be arranged .

The pushing mechanism of the piston of the pumping cylinder consists of a spring against which the piston rod rests, said spring being housed in a box where it can be compressed and lengthened.

The pump retraction motor of the pumping cylinder and the functional control knob are connected to a battery that allows automatic operation of the device, and a handle that allows manual movement control is associated with the piston rod of the pumping cylinder. of the plunger when the power supply battery runs out.

The connection of the pumping cylinder with the therapeutic liquid container has a non-return valve that only allows the passage of circulation in the direction of entry to the pumping cylinder, while the tube incorporating the injection needle is connected to the cylinder of pumping through a non-return valve that only allows the passage of circulation in the direction of exit of the pumping cylinder and that determines the flow of the liquid that passes.

On the other hand, in relation to the injection needle that is incorporated in the end of the tube that leaves the pumping cylinder, a hole plug is provided, so that the needle is capable of being inserted through said cap, this being capable of sealing the needle passage hole when it is removed.

There is thus a device in which, by activating the engine, the rod of the pumping cylinder is retracted, producing an aspiration of a quantity of therapeutic liquid from the container reservoir, while through the subsequent activation of the release of the movement of the stem of the The plunger mechanism moves the plunger forward, driving the therapeutic liquid from the inside of the pumping cylinder through the outlet tube to the injection needle, so that said needle has been previously inserted through a plug stopper arranged in a hole made in the trunk of a tree or in the stipe of a palm tree, the therapeutic liquid is injected into said hole, where it is retained by removing the injection needle from the plug stopper of the hole.

With this, the therapeutic liquid is injected into the application hole in an amount determined by the retraction path of the piston of the pumping cylinder, the injection being produced with a pressure determined by the thrust of the thrust mechanism spring, whereby It achieves the injection of a perfectly defined amount of therapeutic fluid and at a constant pressure. The injection pressure can be varied by replacing the spring in the piston thrust mechanism of the injection device, thus allowing the adaptation of the equipment for different treatments and depending on the trees or palms of application.

Therefore, said equipment object of the invention is of certain advantageous characteristics, acquiring its own life and preferential character for the function of injecting therapeutic liquids into tree trunks or stipes of palm trees to which it is intended.

Detailed description of the invention

The object of the invention relates to a device for injecting therapeutic liquids into the trunks of palm trees or stipes, with embodiments that allow the injection to be carried out in a controlled manner in the quantity of the therapeutic liquid and the pressure at the that is injected.

The recommended equipment comprises a device formed by a pumping cylinder (1) connected through a tube (2) with a container container (3) of therapeutic liquid, leaving said pumping cylinder (1) another tube

(4) which incorporates an injector needle (5) at the end. The connection tube (2) between the pumping cylinder (1) and the container container (3) of therapeutic liquid, has a non-return valve (6) that only allows the flow of passage in the direction of entry to the cylinder of pumping (1); while the tube (4) that incorporates the injection needle (5), has an anti-return valve (7) that only allows the passage of circulation in the direction of exit from the pumping cylinder (1), determining at the same time the flow of liquid that passes.

Inside the pumping cylinder (1) there is a piston (8) that is susceptible to axial displacement, said piston (8) being associated with a rod (9) on which a retraction motor (10) acts and which It is supported on a pushing mechanism (11).

The retraction motor (10) is connected to a battery (12) of power supply, in relation to which a control knob (13) is connected in turn, by means of which the operation of the retraction motor can be activated (10), as well as determining the release of the movement of the rod (9) so that the plunger

(8) move forward by the action of the pushing mechanism (11).

Thus, by activating the retraction motor (10) with the control knob (13), a piston displacement (8) is produced backwards, which causes the aspiration of a quantity of therapeutic liquid from the container container (3) to the pumping cylinder (1), while then controlling, by means of the control knob (13), the release of the movement of the rod (9), the pushing mechanism (11) causes the piston to move ( 8) forward, whereby the therapeutic liquid contained in the pumping cylinder (1) is driven through the tube (4), for its exit by the injector needle (5).

Thus, making a hole in the trunk of a tree or the palm of a palm tree and sealing said hole with a plug (14) capable of being pierced with the injector needle (5) and capable of sealing the orifice itself. passage of said injection needle (5) when it is removed, such as a plug (14) as shown in Figures 5 and 6, without this embodiment being limiting, by means of said absorption and impulse operation with the equipment a perfectly determined amount of therapeutic liquid can be injected into the hole of the application tree or palm, with a fixed injection pressure that is what provides the thrust mechanism drive (11).

To effect the drive, the pushing mechanism (11) incorporates a spring (15) that is housed in a box in which it can be compressed and elongated, resting on it the end of the rod (9) of the piston (8), of such that said spring (15) can be replaced, allowing the injection pressure to vary with the equipment and, consequently, the adaptation for the application of different types of treatments of trees or palms and depending on the trees or palms to be treated .

In relation to the piston rod (9) (8), the arrangement of a handle (16) is provided, which can be of any configuration, by means of which the movement of the piston (8) can be manually operated to carry out the injection of the therapeutic liquid in the trees or palm trees, thus being able to use the equipment manually to perform the necessary treatments, when the power supply battery (12) is exhausted.

In combination with the therapeutic liquid injection equipment for the treatment of trees or palm trees, a GPS system (17) is also provided, by means of which a record of the location of the trees or palms that are treated can be made, allowing to form a control file of the treatments performed.

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The purpose of the request consists of seven claims, the first being independent and the other six directly dependent on it. Said object refers to equipment for injecting liquids into the trunks of trees or palm trees in order to carry out therapeutic treatments. The equipment, as set out in the first and second claims, contains the following technical elements:

-

Pump cylinder, inside which a piston associated with a rod is housed on which a retraction motor operated by a control knob acts.

-

Therapeutic liquid container reservoir

-

Injection needle

-

Non-return valve

The document closest to the object of the request is document D01. References in parentheses refer to that document. D01 discloses an endotherapy device for tree plants through holes made in trees. The device includes a pumping cylinder (1) with a piston (2) inside it capable of axial displacement: the cylinder is connected to a reservoir (23) through a non-return valve (claim 23) and on the other hand with an injection water (41). It has means (3) for the actuation of the piston, through a rod (21) on which a motor (7) and control means (3) act through a CPU for actuation of the piston. The technical advantage sought by the invention is to offer equipment that allows a liquid injection in controlled quantity and pressure. However, the same is disclosed in document D01 (sheet 8, lines 41 to 45). Document D01 contains each and every one of the elements of claims 1 and 2, therefore it is considered that said claims are not new and have no inventive activity (Art. 6.1 and Art. 8.1 LP 11/1986). Document D01 mentions that the drive means can be of any type, as it is mentioned in claim 3 of the application, that these means consist of a power supply battery. Or that said means may be a manually operated puller (13, 14, 15), as described in claim 4 of the application, and as we read in document D04. Therefore, these claims 3 and 4 are neither new nor present inventive activity (Art. 6.1 and Art. 8.1 LP 11/1986) Claim 5 refers to the fact that the thrust mechanism incorporates a spring that can be replaced to vary the pressure Injection This is already mentioned in document D03 (sheet 17, lines 29 to 31). Claim 7 describes a plug that seals the hole in the shaft through which the injection needle is inserted. This characteristic is shown in document D03, in its claim 10. The combination of the technical characteristics of D01 and D03 to obtain the same result is considered to offer no inventive activity. Therefore claims 5 and 7 are new but have no inventive activity Art. 6.1 and Art. 8.1 LP 11/1986). Claim 6 provides a GPS system for locating and recording the treated trees. The use of a GPS (106) in a tree treatment equipment by injection is already described in document D02. Therefore, it would be obvious to a person skilled in the art to combine the technical characteristics of document D01 with D02 and have a reasonable expectation of success. Therefore claim 6 is new but has no inventive activity (Art. 6.1 and Art. 8.1 LP 11/1986). State of the Art Report Page 4/4
