Description

Technical Field

[0001] This utility model relates to the field of plant protection sprayer technology, and in particular to a plant protection sprayer with a multi-spray head. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to plant protection sprayers is also constantly improving. There are usually two types of nozzles for plant protection sprayers: columnar nozzles and fan-shaped nozzles. The spraying effect of the sprayer is mainly controlled by the shape and specifications of the nozzle to ensure the uniformity of spraying.

[0003] Currently used plant protection sprayers are inconvenient to increase the number of atomizing nozzles according to actual needs when spraying large areas of vegetation. This results in a small area that can be sprayed at one time, requiring additional spraying of vegetation that was not sprayed. This leads to low spraying efficiency and is not conducive to the use of plant protection sprayers. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: when the plant protection sprayer currently used is used to spray large areas of vegetation, it is inconvenient to increase the number of atomizing nozzles according to actual needs, which results in a small area being sprayed at one time. It is necessary to spray the vegetation that has not been sprayed separately, resulting in low spraying efficiency and hindering the use of the plant protection sprayer. Therefore, a plant protection sprayer with multi-head nozzles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plant protection sprayer with a multi-nozzle assembly includes a mounting plate and an inlet pipe. The mounting plate has multiple mounting holes. A bracket is fixedly connected to the upper end of the inlet pipe. Two symmetrically arranged branch pipes are rotatably connected to the bracket. Each branch pipe is connected to the inlet pipe through a corrugated pipe.

[0007] Each of the diverter tubes has an extension tube at one end. Each extension tube and the diverter tube are fixedly connected to a threaded ring and an atomizing nozzle. Each extension tube and the diverter tube are fixedly connected to a conical sealing ring, a fixing plate, and a fixing block. Each fixing block is equipped with a sealing component. Each extension tube is fixedly connected to a connecting tube at one end. A threaded sleeve is rotatably connected to the connecting tube. The threaded sleeve is threaded onto the outside of the corresponding threaded ring. Each connecting tube is fixedly connected to a bent rod inside.

[0008] Preferably, each of the diverter tubes and the extension tubes is fixedly connected to a washer at one end face near the corresponding threaded ring, and the surface of the washer is in contact with the surface of the corresponding threaded sleeve.

[0009] Preferably, each of the sealing components includes a sealing block slidably mounted on the fixed block, one end of each of the bent rods is in contact with the surface of the corresponding sealing block, a spring is sleeved on the sealing block, one end of the spring is fixedly connected to the sealing block, and the other end of the spring is fixedly connected to the inner wall of the fixed block.

[0010] Preferably, a rubber ring is fixedly connected to one side surface of each of the fixing blocks, and the rubber ring is slidably sleeved on the outside of the sealing block.

[0011] Preferably, the bracket is threaded with a threaded rod, the threaded rod is rotatably connected to a rotating ring, and the rotating ring is hinged with two rotating rods, which are respectively hinged to the two diverter pipes.

[0012] Preferably, the threaded rod has an annular groove, and the rotating ring is rotatably connected to the annular groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The number of atomizing nozzles can be easily increased by quickly adding extension tubes according to actual needs, thereby increasing the area to be sprayed at one time, reducing repeated work on unsprayed vegetation, improving the efficiency of large-area vegetation spraying operations, and making the plant protection sprayer more suitable for use in large-scale vegetation protection operations.

[0015] With the help of the threaded rod, rotating ring and rotating rod structure, the spraying angle of the diversion pipe and atomizing nozzle can be easily adjusted, which can better adapt to different vegetation layouts and terrains, making the spraying more uniform and comprehensive, and further improving the effect of plant protection operations.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A plant protection sprayer with a multi-nozzle assembly includes a mounting plate 12 and an inlet pipe 1. The mounting plate 12 has multiple mounting holes for mounting the inlet pipe 1. These mounting holes allow for a secure and sealed connection between the entire device and other parts of the plant protection equipment. A bracket 2 is fixedly connected to the upper end of the inlet pipe 1. Two symmetrically arranged branch pipes 6 are rotatably connected to the bracket 2. Each branch pipe 6 is connected to the inlet pipe 1 via a corrugated pipe 7. Both ends of the corrugated pipe 7 are fixedly and sealed to the corresponding branch pipe 6 and the inlet pipe 1, respectively. Each diverter tube 6 has an extension tube 8 at one end. Each extension tube 8 and the diverter tube 6 are fixedly connected to a threaded ring 13 and an atomizing nozzle 10. Each extension tube 8 and the diverter tube 6 are fixedly connected to a conical sealing ring 16, a fixing plate 15, and a fixing block 18. Each fixing block 18 is equipped with a sealing component. Each extension tube 8 is fixedly connected to a connecting tube 17 at one end. A threaded sleeve 9 is rotatably connected to the connecting tube 17. The threaded sleeve 9 is threaded onto the outside of the corresponding threaded ring 13. Each connecting tube 17 is fixedly connected to a bent rod 21 inside.

[0024] refer to Figure 3Each diverter 6 and extension pipe 8 has a washer 11 fixedly connected to one end face near the corresponding threaded ring 13. The surface of the washer 11 fits against the surface of the corresponding threaded sleeve 9, and the washer 11 can effectively prevent the threaded sleeve 9 from loosening. Each sealing assembly includes a sealing block 14 slidably mounted on the fixing block 18. One end of each bent rod 21 fits against the surface of the corresponding sealing block 14. A spring 20 is sleeved on the sealing block 14. One end of the spring 20 is fixedly connected to the sealing block 14, and the other end of the spring 20 is fixedly connected to the inner wall of the fixing block 18. A rubber ring 19 is fixedly connected to one side surface of each fixing block 18. 19 is slidably sleeved on the outside of the sealing block 14. Rotating the threaded sleeve 9 causes it to rotate on the connecting pipe 17 and engage with the threaded ring 13 on the diversion pipe 6 or another extension pipe 8. As the threaded sleeve 9 rotates, the connecting pipe 17 gradually approaches the diversion pipe 6 or another extension pipe 8. During this process, the bending rod 21 pushes the sealing block 14 to slide against the elastic force of the spring 20. The pushing of the bending rod 21 can make the sealing block 14 no longer stick to the fixing plate 15, that is, no longer block the pipeline. At the same time, the conical sealing ring 16 ensures the seal at the connection, realizing the connection between the extension pipe 8 and the diversion pipe 6 or the extension pipe 8, thereby increasing the number of atomizing nozzles 10.

[0025] refer to Figure 1 The support 2 is threaded with a threaded rod 4, and a rotating ring 5 is rotatably connected to the threaded rod 4. Two rotating rods 3 are hinged to the rotating ring 5, and the two rotating rods 3 are respectively hinged to two diverter pipes 6. The threaded rod 4 has an annular groove, and the rotating ring 5 is rotatably connected to the annular groove. Since the threaded rod 4 is threaded to the support 2, when the threaded rod 4 is manually rotated, it will move along its own axis, driving the rotating ring 5 to move. The rotating ring 5 pushes or pulls the diverter pipes 6 through the hinged rotating rods 3, causing the two diverter pipes 6 to rotate relative to the support 2. The included angle between the two diverter pipes 6 changes, thereby adjusting the spraying angle of the diverter pipes 6 and the atomizing nozzle 10, which is convenient for optimizing the spraying range for different vegetation distributions.

[0026] In this invention, when it is necessary to increase the number of atomizing nozzles 10, the extension pipe 8 is connected to the diversion pipe 6 through the connecting pipe 17. The threaded sleeve 9 is rotated so that it rotates on the connecting pipe 17 and engages with the threaded ring 13 on the diversion pipe 6 or another extension pipe 8. As the threaded sleeve 9 rotates, the connecting pipe 17 gradually approaches the diversion pipe 6 or another extension pipe 8. During this process, the bending rod 21 pushes the sealing block 14 to slide against the elastic force of the spring 20. In the initial state, under the elastic force of the spring 20, the surface of the sealing block 14 is tightly attached to the surface of the fixing plate 15, achieving the sealing and blocking of the pipe. The bending rod 21 can push... This prevents the sealing block 14 from sticking to the fixing plate 15, thus preventing the pipeline from being blocked. At the same time, the conical sealing ring 16 ensures the seal at the connection, enabling the connection between the extension tube 8 and the diversion tube 6 or the extension tube 8, thereby increasing the number of atomizing nozzles 10. To reduce the number of nozzles, the threaded sleeve 9 is rotated in the opposite direction, and the sealing block 14 is reset under the elastic force of the spring 20. The extension tube 8 can then be removed, making it convenient to connect the extension tube 8 to the extension tube 8, or the extension tube 8 and the diversion tube 6, according to actual usage needs. An extension tube of appropriate length can also be selected according to actual needs to quickly increase the number of atomizing nozzles 10.

[0027] Water is pumped into the inlet pipe 1 and then split into two branch pipes 6 via the corrugated pipe 7. When the extension pipe 8 is connected to the branch pipe 6 or the extension pipe 8, the water flow can be transmitted to each atomizing nozzle 10 through the connected pipe. At the connection between the extension pipe 8 and the branch pipe 6 or the extension pipe 8, the water path is sealed by sealing components, conical sealing rings 16, etc. When the threaded sleeve 9 is tightened to connect the connecting pipe 17 to the corresponding pipe, the bending rod 21 pushes open the sealing block 14, and the water path is open. When the threaded sleeve 9 is loosened, the spring 20 resets the sealing block 14, which can cut off the water path of that section, realizing the control of water path opening and closing when adjusting the number of nozzles.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; they can refer to mechanical connection or electrical connection; they can refer to direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
