Description

Technical Field

[0001] This utility model relates to the field of spray head technology, and more specifically, to a pesticide atomizing spray head device with adjustable spray range. Background Technology

[0002] The nozzle is a crucial component, or even the main component, in spraying, misting, oiling, and sandblasting equipment, and it is widely used in agricultural activities.

[0003] In pesticide sprayers, pesticides, as auxiliary fertilizers for crops, typically need to be sprayed evenly onto the surface of the crops. Existing pesticides are often mixed with water and atomized under pressure to achieve even coverage. However, traditional atomizing sprayers are usually single or multiple linear nozzles, resulting in a limited spray range and weak atomization effect, failing to achieve efficient spraying.

[0004] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a pesticide atomizing nozzle device with adjustable spraying range, which has the advantages of strong practicality, diversified warning and protection, and easy replacement, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned advantages of high practicality, diverse warning and protection features, and ease of replacement, the specific technical solution adopted by this utility model is as follows:

[0009] An adjustable spraying range pesticide atomizing nozzle device includes a spray gun. One end of the spray gun is connected to a three-way connector, and multiple first threaded nozzles are welded to the end of the three-way connector away from the spray gun. A main spraying rod is threadedly installed at the first threaded nozzle in the middle of the three-way connector, and two auxiliary spraying rods are threadedly installed at the first threaded nozzles on the left and right sides of the three-way connector. Multiple second threaded nozzles are equidistantly installed on the bottom surface of the main spraying rod and the auxiliary spraying rods, and an atomizing nozzle is threadedly installed on each second threaded nozzle. A support base is welded and fixed to the top surface of the main spraying rod and the auxiliary spraying rods, and a connecting rod is threadedly installed on the support base. A knob is fixed to the top of the connecting rod, and a disc-shaped sealing plug is interference-fitted to the bottom of the connecting rod. The disc-shaped sealing plug is located inside the main spraying rod or the auxiliary spraying rod, and the disc-shaped sealing plug is oriented towards the second threaded nozzle.

[0010] Furthermore, one end of both the main spray bar and the auxiliary spray bar is integrally formed with a threaded connecting sleeve, and the threaded connecting sleeve is threadedly connected to the first threaded nozzle. A rubber ring abuts against the connection between the threaded connecting sleeve and the first threaded nozzle, and another rubber ring abuts against the connection between the atomizing nozzle and the second threaded nozzle.

[0011] Furthermore, the upper end of the connecting rod is integrally formed with a threaded portion, and the top surface of the support base is provided with a threaded hole corresponding to the threaded portion.

[0012] Furthermore, the outer diameter of the disc-shaped sealing plug matches the inner diameter of the second threaded nozzle.

[0013] Furthermore, the upper end of the atomizing nozzle is provided with an annular thread structure, and the inner ring of the annular thread structure is provided with an internal thread corresponding to the second threaded nozzle.

[0014] Furthermore, the top surfaces of both the main spray bar and the auxiliary spray bar are provided with through holes corresponding to the connecting rods, and rubber sealing rings are embedded and installed inside the through holes.

[0015] Furthermore, the knob consists of a disc-shaped portion and a strip-shaped hand-rotating portion integrally injection molded on its top, and the knob is interference-fitted with the threaded portion of the connecting rod.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) This utility model has a main spray rod and two auxiliary spray rods threadedly installed at the three-joint of the spray gun. The main spray rod and the two auxiliary spray rods are arranged in a fan-shaped structure. Since each atomizing nozzle of the main spray rod and the two auxiliary spray rods is equipped with a corresponding knob, by rotating the knob on the support base, the connecting rod moves up and down about the support base under the action of the threaded part. Then, the connecting rod drives the disc-shaped sealing plug to insert or disengage from the sealing connection with the second threaded nozzle, so that several atomizing nozzles of the main spray rod and the two auxiliary spray rods can be opened and closed as needed. The coverage of pesticide spraying is adjusted by the number of atomizing nozzles opened, thereby achieving the effect of adjusting the pesticide spraying range.

[0018] (2) This utility model has multiple first threaded nozzles on the three-joint. By bringing the threaded connecting sleeves of the main spray rod and the two auxiliary spray rods close to the multiple first threaded nozzles, the threaded connecting sleeves are threadedly connected to the first threaded nozzles. The rubber ring on the inner side of the threaded connecting sleeve maintains the seal of the connection with the first threaded nozzle. On this basis, the atomizing nozzle also adopts a threaded structure and is threadedly connected to the second threaded nozzle. The rubber ring maintains the seal of the connection with the second threaded nozzle. The threaded installation method meets the needs of loading, unloading and replacing the main spray rod, auxiliary spray rod and atomizing nozzle. At the same time, by replacing the rubber ring between the threaded connecting sleeve and the first threaded nozzle with a circular rubber gasket, one or two first threaded nozzles of the three-joint can be blocked according to actual needs, so that the main spray rod or a single auxiliary spray rod can spray pesticides normally, thereby further meeting the needs of pesticide spraying range adjustment.

[0030] Example 1

[0031] refer to Figure 1 , Figure 2 and Figure 4According to an embodiment of the present invention, an adjustable spraying range pesticide atomizing nozzle device includes a spray gun 1. One end of the spray gun 1 is connected to a three-way connector 2, and a plurality of first threaded nozzles 8 are welded to the end of the three-way connector 2 away from the spray gun 1. A main spraying rod 3 is threadedly installed at the first threaded nozzle 8 in the middle of the three-way connector 2, and two auxiliary spraying rods 4 are threadedly installed at the first threaded nozzles 8 on the left and right sides of the three-way connector 2. A plurality of second threaded nozzles 9 are equidistantly installed on the bottom surface of the main spraying rod 3 and the auxiliary spraying rods 4, and an atomizing nozzle 6 is threadedly installed on each second threaded nozzle 9. A support base 10 is welded and fixed to the top surface of the main spraying rod 3 and the auxiliary spraying rods 4, and a connecting rod 11 is threadedly installed on the support base 10. A knob 7 is fixed to the top of the connecting rod 11, and a disc-shaped sealing plug 15 is interference-connected to the bottom of the connecting rod 11. The disc-shaped sealing plug 15 is located inside the main spraying rod 3 or the auxiliary spraying rod 4, and the disc-shaped sealing plug 15 is positioned facing the second threaded nozzle 9.

[0032] The above structure allows the main spray bar 3 and the two auxiliary spray bars 4 to have several atomizing nozzles 6 open and close as needed (the main spray bar 3 and the two auxiliary spray bars 4 are arranged in a fan shape, and the number of atomizing nozzles 6 opening and closing is adjusted by increasing the diameter of the fan shape). The coverage area of ​​pesticide spraying is adjusted by the number of atomizing nozzles 6 opening, thereby achieving the effect of adjusting the pesticide spraying range. The spray gun 1 can be a rubber hose and is connected to an external pesticide storage tank or liquid fertilizer applicator. The principle of the atomizing nozzles 6 is a known existing technology, and there are mature products available. Therefore, no further explanation of its principle will be given.

[0033] Example 2

[0034] refer to Figure 1 Both the main spray bar 3 and the auxiliary spray bar 4 have a threaded connecting sleeve 5 integrally formed at one end, and the threaded connecting sleeve 5 is threadedly connected to the first threaded nozzle 8. A rubber ring 14 abuts at the connection between the threaded connecting sleeve 5 and the first threaded nozzle 8. Another rubber ring 14 abuts at the connection between the atomizing nozzle 6 and the second threaded nozzle 9.

[0035] By replacing the rubber ring 14 between the threaded connecting sleeve 5 and the first threaded nozzle 8 with a circular rubber gasket, one or both first threaded nozzles 8 of the three-joint 2 can be sealed as needed, allowing the main spray bar 3 or a single auxiliary spray bar 4 to spray pesticides normally, thereby further meeting the requirements for adjusting the pesticide spraying range.

[0036] Example 3

[0037] refer to Figure 1 The upper end of the connecting rod 11 is integrally formed with a threaded part 13, and the top surface of the support base 10 is provided with a threaded hole corresponding to the threaded part 13.

[0038] The threaded portion 13 is provided so that the connecting rod 11 can be threadedly connected to the threaded hole of the support base 10 to meet the lifting and lowering requirements of the connecting rod 11. A limit ring is also provided at the bottom of the threaded portion 13 to prevent the threaded portion 13 from disengaging from the support base 10.

[0039] Example 4

[0040] refer to Figure 1 The outer diameter of the disc-shaped sealing plug 15 matches the inner diameter of the second threaded nozzle 9.

[0041] This structure increases the fit between the disc-shaped sealing plug 15 and the second threaded nozzle 9, thus maintaining the sealing of the connection between the two.

[0042] Example 5

[0043] refer to Figure 1 The upper end of the atomizing nozzle 6 is provided with an annular thread structure, and the inner ring of the annular thread structure is provided with an internal thread corresponding to the second threaded nozzle 9.

[0044] The ring-shaped thread structure allows for the threaded connection between the atomizing nozzle 6 and the second threaded nozzle 9, thus meeting the requirements for the installation, removal, and replacement of the atomizing nozzle 6.

[0045] Example 6

[0046] refer to Figure 1 Both the main spray bar 3 and the auxiliary spray bar 4 have through holes on their top surfaces corresponding to the connecting rod 11, and rubber sealing rings 12 are embedded and installed inside the through holes.

[0047] By using the through hole and the rubber sealing ring 12, the sealing between the two is maintained while allowing the connecting rod 11 to move up and down, thus preventing leakage.

[0048] Example 7

[0049] refer to Figure 1 and Figure 3 The knob 7 consists of a disc-shaped part and a strip-shaped hand-rotating part integrally injection molded on its top, and the knob 7 is interference-fitted with the threaded part 13 of the connecting rod 11.

[0050] The knob 7 facilitates the rotation of the connecting rod 11, allowing the connecting rod 11 to move up and down through the threaded part 13 and the threaded hole of the support base 10, thus meeting the opening and closing requirements of the atomizing nozzle 6.

[0051] Working principle: By bringing the threaded connecting sleeves 5 of the main spray rod 3 and the two auxiliary spray rods 4 close to the multiple first threaded nozzles 8, the threaded connecting sleeves 5 are threadedly connected to the first threaded nozzles 8. The rubber ring 14 on the inner side of the threaded connecting sleeve 5 maintains the seal between the connection and the first threaded nozzles 8, thus achieving the installation of the main spray rod 3 and the two auxiliary spray rods 4. Furthermore, the atomizing nozzle 6 also uses a threaded structure to be threadedly connected to the second threaded nozzle 9, and the rubber ring 14 maintains the seal between the connection and the second threaded nozzle 9, thus achieving the installation of the atomizing nozzle 6. When adjusting the spray range, since each atomizing nozzle 6 of the main spray rod 3 and the two auxiliary spray rods 4 is equipped with a corresponding knob 7, the support base is rotated... The knob 7 on the 10 causes the connecting rod 11 to move up and down relative to the support 10 under the action of the threaded part 13. In turn, the connecting rod 11 drives the disc-shaped sealing plug 15 to insert or disengage from the sealing connection with the second threaded nozzle 9, so that a number of atomizing nozzles 6 of the main spray rod 3 and the two auxiliary spray rods 4 can be opened and closed as needed. The coverage of pesticide spraying can be adjusted by the number of atomizing nozzles 6 that are opened. At the same time, by replacing the rubber ring 14 between the threaded connecting sleeve 5 and the first threaded nozzle 8 with a circular rubber gasket, one or two first threaded nozzles 8 of the three-joint 2 can be blocked according to actual needs, so that the main spray rod 3 or a single auxiliary spray rod 4 can spray pesticides normally, thereby further meeting the needs of pesticide spraying range adjustment.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
