[0002] Technical Field

[0003] The invention relates to the injection device that can dispense the water entering at different pressure levels from the flow line and the liquid chemical in the storage barrel mounted in its reservoir by mixing. Injection device liquid chemical is dispensed with the help of liquid and / or hydraulic pressure with systems that can be connected to the outlet port (sprinkler, drip, spray, release, etc.). In addition, the amount of liquid chemical dispensed, and the amount of proportionally hydraulic pressurized water dispensed can be precisely adjusted or bypassed with the single valve system.

[0004] State of the Art

[0005] Today, agricultural methods that create added value in agriculture are developing day by day with the fact that agriculture has a very important share in the economic resources of many countries. Earlier maturation, more durable plants, increased yield and decreased labor lead to a new productivity and productivity in agriculture. The most important inputs that provide such agricultural efficiency and productivity are agricultural chemicals that make up agricultural fertilizers and pesticides.

[0006] One of the preferred methods to dispense agricultural chemicals to plants is to dispense the fertilizer and water mixture from the soil to plants. Various methods are used for the application of fertilizers and other agricultural chemical products through an irrigation system. Thus, it is ensured that agricultural chemicals that are well mixed with irrigation water are transported to the cultivation area.

[0007] Systems that enable the mixture of agricultural chemicals and water to be dispensed to plants from soil or leaves usually require a pump motor and therefore energy. These and similar structures create disadvantages such as complex systems and high costs.

[0008] Some systems use valve or valve systems to adjust the amount of mixture of the liquid chemical with water. However, most of the time, 45-degree rotating valves do not provide precision adjustment due to their nature and create difficulty in use with the use of multiple valves. Thus, the opportunity to use the liquid chemical effectively is eliminated. The invention, which is the subject of the patent numbered "US8746593B2" in the state of the art, comprises a liquid chemical dispenser for an irrigation system, in the first embodiment, a removable feeding container for the chemical, containing a valve that prevents the chemical from spilling during the connection of the container to the dispenser. This feature allows the container to be mounted in an inverted position on the dispenser without the contents of the container being lost. In a second embodiment, the chemical container comprises a membrane that is pierced by a dip tube when the container is attached to the dispenser. A section of the immersion tube forms an annular ventilation passage in the membrane around the immersion tube to provide vacuum evacuation. The configuration of the containers significantly reduces the possibility of accidental contact with the contents, and the simple design allows the containers to be disposable.

[0009] A fertilizer applicator is provided to be used with the sprinkler line system of the invention subject to the patent numbered "US5178181A", the art of which is known. The applicator consists of a fertilizer container with integrated inlet and outlet tubes. The water is fed to the bottom of the fertilizer container through an inlet-outlet tube, where it dissolves or dilutes a portion of the solid or liquid fertilizer and forms a filtered concentrated solution. This concentrate constantly passes through the fertilizer and rises to the outlet tube and flows downwards here. The concentrate is then diluted with water from an inlet-outlet tube containing a Venturi whose size controls the flow rate of the concentrate. The diluted concentrate is then transferred to the sprinkler system for application to the vegetation. The applicator has a one-piece, simplified design, has no moving parts and does not leak fertilizer into the drain. In addition, the hole arrangement of the applicator allows the device to be emptied and filled with fertilizer without fertilizer leakage, and then water to flow through the fertilizer at any selected time, which makes the process more automated.

[0010] The invention in the state of the art, which is the subject of the patent numbered "US7690392B1", is a mixing body for directing a part of a liquid, for example water flow, to a cartridge consisting of fertilizers, fungicides, hormones, pesticides or the like to form wastewater. The wastewater is returned to the water flow and goes to a downstream sprinkler system or application system. The cartridge, which may contain liquid concentrate, is placed in the mixing body with inlet and outlet one-way valves that pierce the sealing layer of the cartridge. The diluted wastewater exits the outlet one-way valve and is thus transmitted to the irrigation system. The amount of waste can be regulated by a needle valve that controls the amount of waste coming out of the manifold. The mixing body has a locking system to securely hold the cartridge in place. There is also a plate to protect the user from sharp inlet and outlet valves when the cartridge is removed.

[0011] The invention, which is the subject of the patent numbered "US8210451B1", which is in the state of the art, is a chemical dispenser directly connected to a sprinkler system containing a reservoir containing an open top, a cover, a water inlet opening, a solution outlet opening and a basket positioned between the tap and the lid. A saddle clamp element is integrally formed with the reservoir connected to the main utility water line. A reservoir water inlet line interfaces with the main utility water line at one end and the water inlet opening of the reservoir at the other end. A solution discharge line having an outlet extends to the main water inlet line and is connected to the reservoir through the clamp. The water enters the reservoir through the water inlet line and filters the solid chemical placed in the basket and forms an aqueous solution. Then, the solution is withdrawn from the solution discharge line with the pressure difference in the network utility water line flow formed by the restriction of the nozzle in the network utility water line. A metering / shut-off valve is connected to the solution discharge line to control and close the liquid volume.

[0012] As a result, due to the abovementioned disadvantages and the insufficiency of the current solutions regarding the subject matter, a development is required to be made in the relevant technical field.

[0062] Detailed Description of the Invention

[0063] The invention relates to an injection device (1) that can mix and dispense the liquid chemical in the storage barrel (60), which can be mounted in the reservoir (11) with the water entering the flow line, with the help of liquid pressure and / or hydraulic pressure. In the embodiment of the invention, the body (20) of the injection device (1) and the parts structured around the body (20) are as shown in Figure 1. The Venturi inlet tube (22), which is the inlet side of the water dispensed from the flow line to the injection device (1), and the Venturi outlet tube (21), which is the outlet side where the liquid chemical mixture with water is dispensed, are shown. The arrangement of the valve (10), which regulates the amount of liquid chemical dispensing and the hydraulic pressure, the storage barrel (60) that stores the liquid chemical and the pile (40) that can be fixed to the soil are shown in the frame of the reservoir (11). The body (20), which holds structural elements such as valve (10), storage barrel (60), Venturi tube (25), pile (40) together and serves as a skeleton, is the main component.

[0064] As shown cross-sectionally in Figure 4, it is the Venturi tube (25) connected to the body (20), including the Venturi inlet tube (22) and the Venturi outlet tube (21), positioned horizontally with respect to the base of the body (20) as a monolithic tube. There is a Venturi throat (23) in the narrowed section of the Venturi tube (25), which creates a vacuuming effect with the negative pressure formed in the Venturi opening (24) by increasing the water speed. A mixture of water and liquid chemicals is dispensed from the Venturi inlet tube (22) and from the Venturi outlet tube (21). There is a connected Venturi opening (24) that can vacuum the liquid chemical in the narrowing conical throat of the Venturi tube (25). Thus, with the increase in the water velocity passing through the narrowing conical throat of the Venturi tube (25), vacuuming can be performed with the negative pressure formed in the Venturi throat (23) to absorb the liquid chemical from the Venturi opening (24).

[0065] Tube or hose assembly can be made to dispense a mixture of water or liquid chemicals to both the Venturi inlet tube (22) and the Venturi outlet tube (21). The Venturi inlet tube (22) is injected with water from the flow line, which can usually be adjusted for pressure and flow in connection with the valve. With the tube or hose that can be connected to the Venturi outlet tube (21), it is possible to apply a liquid chemical suitable for different uses. With these connections, the water and liquid chemical mixture can be dispensed by systems such as dripping, sprinkling, spraying, releasing, etc.

[0066] The body (20) has a reservoir (11) with an opening in the ceiling. While the reservoir (11) is integrated with the body (20) on the wall ceiling, there is no contact between the base part and the body (20). At the bottom of the reservoir (11), there is the body tube (28) with the cylinder opening where the valve tube (15) enters and the probe slot (30) for mounting the outlet probe (31) to the body tube (28). In addition, there is a gasket (19) at the bottom of the reservoir (11) to prevent liquid or air leakage of the storage barrel opening (61) after the assembly of the storage barrel (60) to the reservoir (11).

[0067] There is a first mounting thread (13) on the inner wall of the reservoir (11) and a second mounting thread (14) on the outer wall. The valve (10) has a valve chamber (17) with an opening in the ceiling. The inner wall of the valve chamber (17) has a third mounting thread (26), and the outer wall has a valve (10) surface that can be turned manually. In addition, there is a fourth mounting thread (62) in the storage barrel opening (61), which is the opening of the storage barrel (60). Thus, the first mounting thread (13) and the fourth mounting thread (62) are functionally connected to mount the body (20) reservoir (11) and the storage barrel (60), and the second mounting thread (14) and the third mounting thread (26) are functionally connected to mount the body (20) reservoir (11) and the valve (10). The mounting threads (13, 14, 26, 62) are in a spiral structure that can be moved on the vertical axis by rotating on the horizontal axis on the surface in contact with each other for functional connection.

[0068] There is a pile (40) that can be fixed to the ground, which is removably mounted to the pile slot (42) at the base of the body (20) and extends in the vertical axis compared to the base of the body (20). The pile (40) is in a pointed structure with a thin line at the four poles, extending from end to end and joining the lines at the end. Thus, it is ensured that the injection device (1) is fixed to the ground in order to remain stable. The pile (40), which can be mounted or removed by rotating in the horizontal axis to the pile slot (42), can be used at any time. In addition, as a result of this structure, while the pile (40) is fixed in the soil, the injection device (1) can be separated from the pile (40) and turned over and the storage barrel (60) can be removed from the reservoir (11) by keeping the liquid chemical. In the storage barrel (60) to which the liquid chemical is supplemented, the reverse of these process steps can be done.

[0069] There is a transfer tube (50) in the vertical axis in connection with the Venturi opening (24). As shown in Figure 3, there is an inlet tube (54) and outlet tube (52) separated from each other by a wall on the inner wall of the transfer tube (50) and there is an inlet opening (53) and outlet opening (51) at different distances on the outer wall. The body of the transfer tube (50) is in a cylinder structure and its end can be conical so that it can pierce the membrane that can close the storage barrel opening (61). The cavity located at the center of the transfer tube (50) forms the inlet tube (54) and this cavity joins the inlet openings (53). The inlet tube (54) forms the cavity outlet tube (52) on the outer wall and this cavity joins the outlet openings (51). The outer wall of the outlet tube (52) also forms the outer wall of the transfer tube (50). Thus, it forms the outlet tube (52) in which it is connected with the outlet openings (51) that convey the liquid chemical in the storage barrel (60) to the Venturi opening (24). It forms the inlet openings (53) where it is connected with the inlet tube (54) that transmits the water entering from the flow line to the storage barrel (60). In addition, there may be triangular inlet openings (53) and outlet openings (51) so that the liquid chemical can be dispensed ascending or descending. These figures also determine the amount of water and liquid chemical dispensing, and the transfer tube (50) with inlet openings (53) and outlet openings (51) formed in different ways can be mounted.

[0070] As shown cross-sectionally in Figures 4,5 or 6, inlet tube (54) is connected to hydraulic tube

[0071] (55). The hydraulic tube (55) extends from the center of the Venturi opening (24) in the direction of the Venturi inlet tube (22). Thus, some of the water coming from the flow line passes through the hydraulic tube (55) to the inlet tube (54) and then to the inlet openings (53) and storage barrel (60). The water reaching the storage barrel (60) both dilutes by mixing with the liquid chemical and creates hydraulic pressure in the storage barrel (60) and provides the dispensing of the liquid chemical mixture to the Venturi opening (24).

[0072] The injection device (1) is provided with the valve (10) so that the ratio of the liquid chemical and the water mixture can be adjusted. As shown in Figure 2, the valve (10) includes the valve chamber (17) with the opening in its ceiling, the valve tube (15) connected to its base, and the third mounting thread (26) located on the inner wall of the valve chamber (17). The valve (10) may have recesses and protrusions on the outer wall for easy manual translation. The valve tube (15), to which it is connected in the vertical axis to the base of the valve (10), moves simultaneously with the valve (10). The valve tube (15) in the opening of the body tube (28) is in a cylinder structure and the transfer tube (50) in a cylinder structure is placed in the opening of the valve tube (15). There are gaskets (19) on the inner and outer wall of the valve tube (15) between the body tube (28) and the transfer tube (50) to prevent liquid or air leakage. There are valve tube openings (16) to convey the liquid chemical to the outlet opening (51) in a section of the wall of the valve tube (15). Thus, the valve (10), which can rotate 360° in the horizontal axis and thus move in the vertical axis, and the valve tube (15) can close and open the outlet openings (51) and inlet openings (53) for the dispensing of the liquid chemical. When the outlet openings (51) and inlet openings (53), which can be closed with the valve tube (15) at the same time, are fully closed, the water in the flow line is disconnected from the storage barrel (60) and the mixture is bypassed and only water is dispensed in the Venturi tube (25). The amount of liquid chemical dispensing is adjusted by the movement of the valve tube (15) on the outlet openings (51), and the hydraulic pressure is adjusted by the movement on the inlet openings (53). This adjustment, which can be made simultaneously with a single valve (10), provides liquid chemical dispensing in a proportional manner.

[0073] As shown in Figure 1 or 5, there is a storage barrel (60) at the top of the injection device (1). The storage barrel (60) comprises the storage barrel opening (61) with the outlet opening, the discharge cover (63) that can close and open the opening at the bottom and the fourth mounting thread (62) on the outer wall of the storage barrel opening (61). It creates liquid pressure by storing the liquid chemical in the storage barrel (60) placed in the vertical axis according to the ground. The fourth mounting thread (62) and the first mounting thread (13) are functionally connected, and the storage barrel (60) is mounted to the reservoir (11). The discharge cover (63) can be opened for the discharge of excess compressed air or liquid chemical that may occur or for the dispensing of liquid chemical by the open-air pressure compensation of the injection device (1) in case of bypassing hydraulic pressure.

[0074] As shown in Figure 6, the injection device (1) can also be used by reversing it. In this case, the transfer tube (50) does not have liquid chemical contact since the liquid chemical will collapse to the bottom of the storage barrel (60). In order for the reversed injection device (1) to dispense the liquid chemical, the outlet probe (31) is mounted to the body tube (28) and the inlet probe (33) is mounted to the valve tube (15). The inlet probe (33) passing into the outlet probe (31) is longer for the separation of the liquid chemical and water dispensing. Thus, the liquid chemical is vacuumed with the outlet probe (31) to the outlet opening (51) on the transfer tube (50), and the hydraulic water from the inlet opening (53) is transferred to the storage barrel (60) with the inlet probe (33).

[0075] Systems such as dripping, sprinkling, spraying, which can be connected to the Venturi outlet tube (21), which is the outlet side of the water and liquid chemical mixture of the injection device (1), generally operate under high pressure. Since this pressure exerts pressure against the injection device (1), the liquid chemical in the storage barrel (60) can spray into the storage barrel (60) instead of vacuuming in the Venturi opening (24). In order to prevent this situation, some of the water entering the Venturi inlet tube (22) from the flow line passes through the hydraulic tube (55) and reaches the storage barrel (60), thus providing pressure compensation. In addition, since the water entering from the low pressure or low-flow flow line cannot accelerate at the Venturi opening (24), the Venturi vacuuming does not work efficiently. In order to prevent this situation, the discharge cover (63) can be opened for open air pressure compensation and liquid pressure and liquid chemical dispensing can be provided. If water dispensing to the storage barrel (60) is not desired, the hydraulic pressure is inactivated by bypassing the plug that can be placed in the valve tube (15). In addition, the storage barrel (60) is inactivated by bypassing the hydraulic pressure with the plug that can be placed in the valve tube (15) if the dispensing of liquid chemical is desired by vacuuming from the Venturi opening (24) without mounting it to the injection device (1), and the outlet probe (31) mounted to the body tube (28) is immersed in the storage barrel (60) from the opening of the storage barrel opening (61).
