Description

Technology Field

[0001] The present invention relates to a nozzle holder capable of selecting a spray pattern and blocking the flow rate through position adjustment, and more specifically, to a nozzle holder capable of selecting a spray pattern and blocking the flow rate through position adjustment such that the form of spraying through the nozzle (direct spray and mist spray) can be selected or the supply of pesticide can be completely blocked by rotating an adjustment handle protruding from the rear of a spray adjustment body. Background Technology

[0003] Generally, for pest control in the agricultural field, water is supplied, and then a certain amount of liquid or powder pesticide is supplied and diluted before spraying.

[0004] Nozzles for controlling pesticides are supplied in various forms, and Patent Registration No. 1795496 (registered on Nov. 02, 2017) and Patent Publication No. 1997-11824 (published on April 25, 1997) have a spray control body installed on the upper side of a hose connector to which the hose of a sprayer is connected, and a spray volume control shaft connected to a spray volume control handle in the horizontal direction from the spray control body is reciprocated to control the supply volume of pesticide supplied from the hose so that it is sprayed through a front spray nozzle.

[0005] However, although it has the feature of being able to adjust the amount of pesticide sprayed by removing the space of the spray supply port as the spray volume control knob is rotated, when opening to supply the maximum amount of pesticide, a strong force is continuously applied even when the spray volume control shaft has moved backward to the maximum extent and can no longer move backward, causing the connection between the spray volume control knob and the spray volume control shaft to be released. Conversely, when closing it to stop using pesticide, a strong force is continuously applied even when it has moved forward to the maximum extent and can no longer move forward, causing excessive force to be applied and resulting in damage to the packing and parts.

[0006] In addition, when the pesticide is stored in a locked state to stop supplying it as described above and then used again, the liquid, which consists of a mixture of powder and water contained in most pesticides, hardens and clogs the part, making it difficult to use again and requiring repair or replacement of parts.

[0008] To prevent such defects, the applicant’s prior patent registration No. 10-2033307 (registered on October 11, 2019), titled ‘Damage Prevention Structure for Pesticide Spray Nozzles,’ comprises: a spray control body having a spray supply section connected to a hose connector having a hose connection screw formed thereon, a spray fixing screw to which a control member fixing member is coupled on the inner surface, a spray volume control member connected to a spray volume control handle that controls the pesticide supply amount by reciprocating movement according to rotation of a spray volume control shaft coupled to the inner diameter of the spray control body, and a spray pipe coupled to the connector having a spray nozzle formed at its tip, wherein

[0009] The width of the spray volume adjustment screw is made to have the same width as the spray volume adjustment male screw, the gap between the spray fixing screw and the spray volume adjustment screw is larger than the gap of the spray volume adjustment male screw, and the gap between the spray volume adjustment screw and the pipe connecting screw is formed to be larger than the gap from the tip of the spray volume adjustment male screw to the tip of the protruding shaft.

[0010] However, this prior art is installed so that when the maximum and minimum opening values ​​are adjusted during pest control connected to a pesticide sprayer, it does not move further and idles in place, thereby preventing damage to the handle and liquid from hardening over time. However, it has a defect in that it cannot prevent the liquid from hardening because it cannot perform its normal function, as the idler cannot operate normally despite strong water pressure.

[0011] In addition, conventional sprayers are equipped with a separate device in front of the handle to cut off the supply of liquid, resulting in a very complex structure that causes price increases due to the consumption of manufacturing costs and assembly time, as well as various defects such as inconvenience of use and difficulty in repairing in the event of a breakdown.

[0041] The invention relates to a nozzle assembly (10) comprising a spray device (50) including a spray pipe (30) and a nose cap (51) in front of the spray adjustment body (11), wherein a supply hose (16) that compresses and supplies pesticide from a supply motor is supplied through a handle (14) connected via a connector (15), and a spray adjustment body (11) is connected horizontally from the upper side while the handle (14) is installed at an angle to be easy to grip with one hand.

[0042] A spray volume adjustment member (20) that is elongated is installed inside the spray adjustment body (11), spray pipe (30), and spray device (50), and the spray volume adjustment member (20) can be inserted and assembled from the right side of the spray adjustment body (11), and an adjustment handle (21a) is installed at the tip of the nozzle shaft (21) exposed from the spray adjustment body (11).

[0043] By rotating the adjustment handle (21a) to the right, the sealed space (31a) is opened, allowing direct spraying in which pesticide is sprayed far in a single stream from the front spray volume control member (20), and by rotating the adjustment handle (21a) to the left, mist spraying that spreads directly over a wide range from the nozzle (52) is selected, and by further rotating the adjustment handle (21a) to the left, the sealed space (31a) is blocked by the sealing member (28), allowing the supply of pesticide to be blocked. Thus, by adjusting the adjustment handle (21a) so that all three types of pesticide spraying and blocking can be selected, the three types of pesticide spraying selected can be performed with a single spray volume control member (20).

[0044] The above spray volume adjusting member (20) can be molded as a single piece, and can be molded by dividing it into multiple pieces and combining them as needed to reduce costs.

[0048] In the inner diameter of the above-mentioned spray member (54), a front spray adjustment member (42) of the connecting shaft part (40) is installed so that the position of the spray adjustment member (42) is changed according to the position selection of the adjustment handle (21a), thereby determining three types of spray selection through the spray member (54).

[0050] As shown in FIGS. 6 and 8, a spray screw (31) is formed on the right side of a spray pipe (30) in which a supply channel (32) is formed in the inner diameter to be coupled with a spray adjustment body (11), and a sealed space (31a) is formed at the right end of the supply channel (32) in the inner diameter of the spray screw (31) so as to allow selection of supply and blocking of pesticide.

[0051] A sealing member (28) to which a connecting shaft screw (41) is coupled is installed at the right end of the connecting shaft portion (40) located in the supply path (32), and the sealing member (28) is connected to the connecting shaft portion (40) at the front and inserted into the supply path (32), and a sealing ring (28a) is fitted to the part where the diameter increases, and then a blocking portion (28b) with an even larger diameter is formed to control and block the space size of the sealed space (31a).

[0052] A sealing connecting screw (27) of the core shaft (25) is connected to the above-mentioned blocking part (28b) to control the position of the sealing member (28) according to the rotation of a predetermined handle (21a), and the core shaft (25) is located in the inner diameter transfer path (13) of the spray adjustment body (11).

[0054] As shown in FIGS. 7 and 9, a spray volume adjustment screw (12) is installed on the right inner diameter of the spray adjustment body (11), and a handle (14) is installed at an angle downward so that it can be sprayed forward while held with one hand.

[0055] A position adjustment screw (24) is screw-fastened to the inner diameter of the above-mentioned spray volume adjustment screw (12), and a core screw (26) of the core shaft (25) is screw-fastened to the left side. After the adjustment shaft (21) is installed so as to be exposed to the outside to the left side of the above-mentioned position adjustment screw (24), an adjustment handle (21a) is connected to the tip of the adjustment shaft (21).

[0056] The inner diameter of the spray volume adjustment screw (12) includes a fixing nut (22) through which the adjustment shaft (21) passes, and a fixing screw shaft (23) protrudes and is coupled to the spray volume adjustment screw (12), thereby adjusting the position of the spray adjustment member (42) by adjusting the reciprocating position of the position adjustment screw (24) through the rotation of the adjustment handle (21a).

[0059] As illustrated in FIGS. 10 and 11, the spray volume adjusting member (20) can be formed by molding all components into a single structure, or it can be selected to be formed by dividing it into several parts and molding them, and then combining them at each position, as the length is too long and consists of various structures.

[0060] An adjustment screw shaft (23) and a fixing nut (22) are integrally formed on the outer diameter of the adjustment shaft (21) connected to the adjustment handle (21a) so that the adjustment shaft (21) passes through, and a position adjustment screw (24) is formed at the tip of the adjustment handle (21a).

[0061] A core shaft (25) protrudes from the position adjustment screw (24), and a sealing member (28) is connected to the tip of the core shaft (25) to control the opening and closing of the sealing space (31a), and a connecting shaft portion (40) protrudes from the sealing member (28) so that a spray adjustment member (42) is formed at the tip.

[0063] Below, we will explain in detail how the spray amount adjusting member (20) is formed by dividing it.

[0064] As illustrated in FIGS. 12 and 13, a spray adjustment member (42) is installed in the inner diameter of the spray material (54) to adjust the amount of pesticide sprayed according to the movement of the position, and an inner diameter flow path (43) is installed to enable the rotation (vortex) supply of pesticide supplied by forming a spiral at two locations in the circumferential direction, and a connecting shaft part (40) is protruded long from the spray adjustment member (42), and a connecting shaft part screw (41) is formed at the tip.

[0066] As illustrated in FIGS. 14 and 15, the sealing member (28) to which the connecting shaft screw (41) is connected can enter the supply path (32), and a sealing ring (28a) is formed in the portion where the outer diameter increases, and the blocking portion (28b) where the outer diameter increases is larger than the diameter of the sealing space (31a) so that the moving position of the blocking portion (28b) can be blocked.

[0067] The above blocking portion (28b) can form a portion with a portion of the circular diameter removed, and the sealing connection screw (27) of the core shaft (25) can be connected.

[0069] As illustrated in FIGS. 16 and 17, the core shaft (25) is formed with a sealing connection screw (27) to be connected to a sealing member (28), and on the opposite side, a core screw (26) is formed to be connected to a position adjustment screw (24).

[0071] As shown in FIGS. 18 and 19, a position adjustment screw (24) is connected to the inner diameter of the spray volume adjustment screw (12) in a screw manner so that the position is adjusted, and an adjustment shaft (21) is connected to the position adjustment screw (24) so ​​that it is partially exposed to the outside of the spray adjustment body (11), and an adjustment handle (21a) is connected to the tip of the adjustment shaft (21).

[0072] A fixed screw shaft (23) is formed on the outer diameter of the above adjustment shaft (21) and coupled to the spray amount adjustment screw (12), and a fixing nut (22) is formed on the fixed screw shaft (23) and fixed to the outside of the spray adjustment body (11) so that three spray states can be selected according to the rotation of the adjustment handle (21a) and installed to prevent separation due to the movement of the position adjustment screw (24).

[0074] FIG. 20 shows a disassembled perspective view of the spray device of the present invention,

[0075] An inner diameter flow path (43) is formed in the spray adjustment member (42) formed at the tip of the connecting shaft (40), and the spray member (54) into which the spray adjustment member (42) is inserted has a spray hole (55) formed in the center and a plurality of legs (57) protruding to the right, and a spiral outer diameter flow path (56) is formed in both directions on the outer diameter.

[0076] In front of the spray member (54), a packing (53) is pressed by the nozzle (52) to maintain watertightness, and a nozzle hole (52a) is formed in the center of the nozzle (52).

[0077] The nozzle cap (51), which encloses the outer diameter of the nozzle (52), packing (53), and spray member (54), is screw-connected to the front cap connecting shaft (33) of the spray pipe (30) and, depending on the supply status of the pesticide, allows for the selection of direct spraying, where the pesticide is sprayed far in a single stream from the nozzle hole (52a), and mist spraying, where the pesticide spreads out over a wide area directly from the nozzle hole (52a), by controlling the position of the spray adjustment member (42). Additionally, by further rotating the adjustment handle (21a), the system can select to cut off the supply of pesticide to the sealed space (31a) using the sealing member (28).

[0079] The nozzle assembly of the present invention, which is configured such that the spray state selection and blocking are possible according to position adjustment, supplies pesticide to a predetermined pressure through a supply hose (16) connected to a motor for a sprayer, and the supply hose (16) is connected to a handle (14) through a connector (15) and supplies to the inner diameter transfer path (13) of the spray adjustment body (11).

[0080] When the nozzle holder (10) rotates the adjustment handle (21a) while holding the handle (14) with one hand, the adjustment shaft (21) rotates together, and the position adjustment screw (24), which is screw-coupled to the spray volume adjustment screw (12) while passing through the fixing nut (22) and the fixing screw shaft (23), is rotated.

[0081] As the position adjustment screw (24) rotates, it moves to the right side of the spray volume adjustment screw (12) in the drawing, and moves the spray volume adjustment member (20) to the right, causing the sealing member (28) to open the sealed space (31a), so that the pesticide supplied to the transfer path (13) is supplied forward through the inner diameter supply path (32) of the spray pipe (30).

[0082] The pesticide supplied to the front of the supply path (32) adjusts the spraying state by moving the set position in the inner diameter of the leg (57) formed on the spray member (54) of the spray device (50) in the left and right directions in the drawing due to the positional movement caused by the rotation of the spray amount adjustment member (20).

[0083] By rotating the adjustment handle (21a) to move the spray volume adjustment member (20), including the adjustment shaft (21), to the right so that it moves backward, the pesticide supplied through the supply path (32) is supplied to the nozzle (52) through the spray hole (55) and the outer diameter path (56) of the spray member (54), thereby providing a form that allows the pesticide to be sprayed far in a straight line from the nozzle hole (52a) through the inner diameter of the nozzle cap (51) to the outside.

[0084] Then, by rotating the adjustment handle (21a) to move the spray volume adjustment member (20), including the adjustment shaft (21), to the left and advance it, the pesticide supplied through the supply path (32) is supplied to the nozzle (52) through the spray hole (55) of the spray member (54) and the outer diameter path (56), and is sprayed outwardly through the inner diameter of the nozzle cap (51) from the nozzle hole (52a), thereby providing a mist spraying form.

[0085] Accordingly, by rotating the adjustment handle (21a), the adjustment shaft (21) can reciprocate left and right on the spray volume adjustment screw (12) as it rotates the position adjustment screw (24). Therefore, by selecting and spraying direct spraying and mist spraying forms according to the position of the inner diameter passage (43) in the spray adjustment section (42) at the tip of the connecting shaft (40) and the position of the inner diameter of the leg (57) of the spray member (54), selective spraying can be performed according to the type of crop and the control effect and function according to the spraying form of the pesticide.

[0087] In addition, when the spraying of pesticide is to be stopped, the adjustment handle (21a) is rotated so that the adjustment shaft (21) and the position adjustment screw (24) rotate to the left and the spray amount adjustment member (20) is moved to the left, and the sealing member (28) enters the sealed space (31a) as shown in FIG. 6, thereby completely blocking the supply of pesticide to the supply path (32) through the sealing ring (28a).

[0088] The above sealing member (28) performs the opening and closing of the sealed space (31a) and adjusts the spraying state of the pesticide, and at the same time, the sealing design (31a) is blocked to cut off the supply of the pesticide. Since this operation can be determined through the rotational movement of the adjustment shaft (21) and the position adjustment screw (24) according to the rotation of the adjustment handle (21a), direct spraying, mist spraying, and the blocking of the pesticide supply can be quickly selected by adjusting the sealing member (28) through the rotation of the adjustment handle (21a) according to the position adjustment of the spray amount adjustment member (20).

[0089] It is preferable that the above direct spraying, mist spraying, and pesticide supply blocking be installed such that the distance (a) of the core shaft (25), including the core screw (26) and the single-closure connecting screw (27), is equal to or longer than the distance (A) of the core screw (26) and the single-closure connecting screw (27), compared to the gap (A) between the blocking part (28b) and the part where the spray amount adjustment screw (12) starts.

[0090] The position adjustment screw (24) coupled to the inner diameter of the above-mentioned spray volume adjustment screw (12) is installed so that direct spraying, mist spraying, and pesticide supply can be blocked within the range of the gap (c) that rotates inside the right-hand fixed screw shaft (23).

[0092] And since the spray volume control member (20) is formed in a very long shape, each part can be formed by processing a single round bar, but since it is very long, thin, and has a complex structure, it is difficult to process and consume costs, so it can be formed by dividing it into multiple parts and then assembled.

[0093] To explain the case where the above-mentioned spray volume adjustment member (20) is divided and molded, the adjustment shaft (21) that separates and connects the adjustment handle (21a) is formed such that the right adjustment screw (24) is formed to the left so that it can rotate and reciprocate within the inner diameter of the spray volume adjustment screw (12).

[0094] The core shaft (25) has a core screw (26) formed on the right side and is screw-coupled with the position adjustment screw (24), and a sealing connection screw (27) formed on the left side and is screw-coupled to the blocking part (28b).

[0095] The sealing member (28) is formed such that a sealing ring (28a) is formed on its outer diameter to maintain watertightness in the sealed space (31a), and a blocking part (28b) with a larger outer diameter is formed to the right of the sealing ring (28a) to stop movement from the outside of the sealed space (31a).

[0096] The connecting shaft part (40) is formed with a connecting shaft part screw (41) on the right side and connected to the sealing member (28) in a screw manner, and a spray adjustment part (42) with an inner diameter passage (43) is formed on the left side so that it can be molded into multiple parts and then assembled for use.

[0098] The above spraying device (50) screw-connects a nozzle cap (51) to a cap connecting shaft (33), supplies a spraying member (54) to the inner diameter of the cap connecting shaft (33), and supplies a packing (53) and a nozzle (52) from the outside. When the nozzle cap (51) is screw-connected to the cap connecting shaft (33), the nozzle (52) presses the packing (53) and is positioned in front of the cap connecting shaft (33), thereby preventing leakage. Furthermore, direct spraying and mist spraying can be selected according to the amount of pesticide supplied forward through the nozzle hole (52a).

[0099] The above spray member (54) has a spiral outer diameter channel (56) formed on its outer diameter so that the pesticide is supplied in a spiral direction while rotating in one direction, and an inner diameter channel (43) is formed in the spray adjustment member (42) so that the pesticide is supplied in a spiral direction to the spray hole (55), thereby allowing the pesticide to be supplied far when directly sprayed while rotating in one direction in a double manner, or allowing guided spraying to be selected depending on the position adjustment of the spray adjustment member (42).
