Description

Technical Field

[0001] This utility model belongs to the field of vegetable spraying technology, specifically relating to a vegetable spraying nozzle. Background Technology

[0002] In the process of vegetable cultivation, it is often necessary to use atomizing nozzles to spray pesticides on vegetables in order to prevent and control diseases and pests.

[0003] Existing sprayers typically use a single nozzle to spray vertically downwards or multiple nozzles at a fixed angle. Due to the obstruction of the outer leaves, traditional spraying methods make it difficult for the pesticide to effectively penetrate and cover the core of the vegetable. This prevents direct contact with pests that like to hide inside the vegetable core, such as aphids, thrips, whiteflies, and flea beetles. In particular, contact pesticides are not very effective at killing pests hidden inside the vegetable core. Utility Model Content

[0004] This invention provides a vegetable spray nozzle that can form a spray overlap area in the central region, thereby improving the spraying effect on the core of the vegetables.

[0005] This utility model provides the following technical solution: a vegetable spray nozzle, including an atomizing nozzle, three of which are arranged in a ring, a hollow ring frame above the three atomizing nozzles, three reference positioning tubes fixedly connected to the bottom end of the hollow ring frame, the angle between the three atomizing nozzles and the corresponding reference positioning tubes can be adjusted by three adjustment mechanisms, and a connecting hose is fixedly connected to the bottom end of each of the three reference positioning tubes, and the three connecting hoses are detachably connected to the three atomizing nozzles respectively.

[0006] Each of the three connecting hoses has a threaded connector fixedly connected to its bottom end, and the threaded connector is threadedly connected to the atomizing nozzle.

[0007] The hollow ring frame has several hollow connecting rods fixedly connected to its inner wall, and the hollow connecting rods communicate with the inner cavity of the hollow ring frame.

[0008] The adjustment mechanism includes a side support plate and a fastening knob. The side support plate is fixedly connected to the side wall of the corresponding reference positioning tube, and the fastening knob passes through the side support plate and is threadedly connected to the corresponding threaded joint.

[0009] The inner wall of the side support plate is fixedly connected with a friction pad, and the friction pad corresponds to the position of the threaded joint.

[0010] Among them, several hollow connecting rods are fixedly connected to the center of a connecting pipe, the connecting pipe is connected to the hollow ring frame through the hollow connecting rod, and a fixing sleeve is fixedly connected to the top of the connecting pipe.

[0011] The connecting pipe is fixedly connected to a liquid medicine delivery pipe on its side wall, and a pipe connector is fixedly connected to the free end of the liquid medicine delivery pipe.

[0012] The beneficial effects of this utility model are: by using the hollow ring frame, the reference positioning tube, the connecting hose and the adjustment mechanism, the orientation of the atomizing nozzle can be adjusted. Then, by adjusting the angle of the three atomizing nozzles, a spray overlap area can be formed in the central area, and the liquid can be dripped into the core of the vegetable by forming liquid droplets in the center of the vegetable leaves, thereby improving the spraying effect on the core of the vegetable.

[0016] Please see Figures 1-4 The present invention provides the following technical solution: a vegetable spray nozzle, including an atomizing nozzle 1, three atomizing nozzles 1 arranged in a ring, a hollow ring frame 2 above the three atomizing nozzles 1, three reference positioning tubes 21 fixedly connected to the bottom end of the hollow ring frame 2, the angle between the three atomizing nozzles 1 and the corresponding reference positioning tubes 21 can be adjusted by three adjustment mechanisms 3, and a connecting hose 22 is fixedly connected to the bottom end of each of the three reference positioning tubes 21, and the three connecting hoses 22 are detachably connected to the three atomizing nozzles 1 respectively.

[0017] In this implementation plan: when the device is installed on the spraying system, the fixing sleeve 41 is fitted onto the nozzle frame driven by the drive device and the fixing sleeve 41 is tightened with bolts. The pipe connector 51 is connected to the delivery pipe. When multiple nozzles are used in combination, the installation spacing of the nozzles is adjusted according to the row spacing of the vegetable planting.

[0018] In normal use, all three atomizing nozzles 1 face downwards. The drive device moves the nozzle frame, which in turn moves the device. The liquid medicine enters the connecting pipe 4 through the liquid medicine delivery pipe 5, and then enters the hollow ring frame 2 through the hollow connecting rod 24. Subsequently, it enters the three connecting hoses 22 through the three reference positioning pipes 21, and then is atomized and sprayed outwards from the atomizing nozzles 1 to spray the liquid medicine onto the vegetables. During the process, the connecting pipe 4 supports the hollow ring frame 2, and in turn supports the reference positioning pipes 21. The angle of the atomizing nozzles 1 is fixed by the side support plate 31 and the fastening knob 32, so that the atomizing nozzles 1 spray steadily downwards.

[0019] When spraying insecticides to kill pests such as aphids, thrips, whiteflies, and flea beetles that like to gather in the tender heart of young cabbage, loosen the fastening of the opposite support plate 31 and threaded connector 23 by rotating the fastening knob 32, and then bend each of the three atomizing nozzles 1 towards the center. After adjusting the angle, tighten the fastening knob 32 again. When the pesticide is sprayed through the atomizing nozzles 1, the spray range of the three atomizing nozzles 1 partially overlaps in the lower center. Compared to other parts, the central part of the vegetable is sprayed with more pesticide. Furthermore, the downward angled spray of the atomizing nozzles 1 allows a larger area of ​​pesticide to be intercepted by the leaves. The overlapping portion of the pesticide solution adheres to the core leaves of the vegetable. After a large amount of pesticide solution accumulates, it drips down along the gaps in the leaves, penetrating deep into the central leaves of the vegetable and directly contacting the pests to kill them. It is particularly effective against contact pesticides such as high-efficiency cypermethrin, bifenthrin, and thiamethoxam. Furthermore, the tilted spraying direction of the atomizing nozzle 1 can apply an initial lateral velocity to the sprayed pesticide solution. The pesticide solution outside the overlapping portion will diffuse towards the outer leaves of the vegetable. While focusing on spraying the center of the vegetable, it can also spray the outer leaves, thus controlling pests on the outer leaves.

[0020] In actual use, staff can adjust the angle of the atomizing nozzle 1 in various ways according to actual needs. For example, when spraying the edge of the planting area, the atomizing nozzle 1 can be adjusted to bend into the planting area to spray the pesticide solution into the vegetable planting area, reducing the amount of pesticide solution sprayed outside the planting area and reducing pesticide waste.

[0021] The bottom ends of the three connecting hoses 22 are all fixedly connected with threaded connectors 23, which are threadedly connected to the atomizing nozzle 1. By setting the threaded connectors 23, it is easy to connect the connecting hoses 22 and the atomizing nozzle 1. The threaded connectors 23 and the atomizing nozzle 1 are threadedly connected according to the threaded connection head method in the prior art.

[0022] Several hollow connecting rods 24 are fixedly connected to the inner wall of the hollow ring frame 2. The hollow connecting rods 24 communicate with the inner cavity of the hollow ring frame 2. By setting the hollow connecting rods 24, the hollow ring frame 2 can be connected to the connecting pipe 4. The hollow ring frame 2 and the hollow connecting rods 24 serve as a support structure, while the internal cavity is used as a channel for the flow of liquid medicine.

[0023] The adjustment mechanism 3 includes a side support plate 31 and a fastening knob 32. The side support plate 31 is fixedly connected to the side wall of the corresponding reference positioning tube 21. The fastening knob 32 passes through the side support plate 31 and is threadedly connected to the corresponding threaded joint 23. The side support plate 31 is made of a hard material, such as steel, to provide a stable support and limiting effect and fix the angle of the atomizing nozzle 1. Bolt holes corresponding to the fastening knob 32 are opened on the side support plate 31. When the fastening knob 32 is locked, the fastening knob 32 is in close contact with the side support plate 31.

[0024] A friction pad 33 is fixedly connected to the inner wall of the side support plate 31, and the friction pad 33 corresponds to the position of the threaded joint 23. By setting the friction pad 33, the resistance encountered by the side support plate 31 and the threaded joint 23 during relative movement can be increased. The frictional resistance during locking is used to position the threaded joint 23, thereby limiting the orientation of the atomizing nozzle 1.

[0025] A number of hollow connecting rods 24 are fixedly connected to a connecting pipe 4 at their center. The connecting pipe 4 is connected to the hollow ring frame 2 through the hollow connecting rods 24. A fixing sleeve 41 is fixedly connected to the top of the connecting pipe 4. The hollow interior of the connecting pipe 4 serves as a conveying channel, and the side wall serves as a supporting structure. Hard plastic or hard metal materials should be used during production.

[0026] A liquid delivery pipe 5 is fixedly connected to the side wall of the connecting pipe 4, and a pipe connector 51 is fixedly connected to the free end of the liquid delivery pipe 5. The liquid delivery pipe 5 uses a long flexible hose to provide length margin for different installation positions, so that the device can be adjusted to the installation position according to the planting spacing of vegetables. The pipe connector 51 is connected to the liquid supply pipe joint.

[0027] The working principle and usage process of this utility model are as follows: Under normal use, all three atomizing nozzles 1 face downwards. The drive device moves the nozzle frame, which in turn moves the device. The pesticide solution enters the connecting pipe 4 through the pesticide delivery pipe 5, then enters the hollow ring frame 2 through the hollow connecting rod 24, and then enters the three connecting hoses 22 through the three reference positioning pipes 21. Finally, it is atomized and sprayed outwards from the atomizing nozzles 1 to spray pesticide onto the vegetables. When spraying to kill pests such as aphids, thrips, whiteflies, and flea beetles that like to gather on the tender hearts of young vegetables, the pesticide solution can be loosened by rotating the fastening knob 32. The side support plate 31 and threaded joint 23 are tightened, and the three atomizing nozzles 1 are bent towards the center. After the angle is adjusted, the tightening knob 32 is tightened again. When the liquid is sprayed out through the atomizing nozzles 1, the spray range of the three atomizing nozzles 1 partially overlaps in the lower part of the center. Compared with other parts, the central part of the vegetable is sprayed with more liquid. The atomizing nozzles 1 spray downwards at an angle. The overlapping part of the liquid will adhere to the core leaves of the vegetable. After a large amount of liquid is collected, it will drip down along the gaps in the leaves and penetrate into the central leaves of the vegetable, directly contacting the pests and killing them.
