Description

Technical Field

[0001] This utility model relates to the field of pest control, and in particular to a liquid spraying device for controlling pests and diseases. Background Technology

[0002] Pesticide spraying equipment is an agricultural machine that controls crop pests and diseases by precisely spraying pesticides or biological agents. Its core functions include intelligent droplet control, multi-angle nozzle adjustment, and environmental adaptability optimization. This type of equipment, combined with sensor technology, airflow-assisted systems, or electrostatic adsorption functions, can achieve uniform coverage on both sides of leaves and at different densities in the canopy, reducing pesticide waste and environmental pollution, while improving the control effect against hidden pests. It is widely used in green precision pest control for field crops, orchards, and greenhouse agriculture.

[0003] In the prior art, compared with the Chinese utility model disclosure CN222090609U, which discloses a liquid spraying device for controlling rice diseases and pests, the spraying range is improved by the sprayer-like state. However, in actual use, it was found that when spraying some lush vegetation, different pests will be attached to the upper and lower surfaces of the branches and leaves. However, if the spraying is only carried out on one side, it is not possible to spray all parts well, so the spraying effect on some blind spots is not ideal. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide spraying device for preventing and controlling pests and diseases in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pesticide spraying device for controlling pests and diseases includes a spraying mechanism for rotating spraying, a rotating mechanism, and a dual-shaft gearbox for providing rotational power to the spraying mechanism. The rotating mechanism has two parts, each disposed on one of the two output shafts of the dual-shaft gearbox. The rotating mechanism has a circular structure, and a plurality of adjusting mechanisms for adjusting the state of the spraying mechanism are evenly arrayed on the outer circular end face of the rotating mechanism. The spraying mechanism is mounted on the adjusting mechanisms.

[0007] The rotating mechanism includes two fixed disks, and the adjusting mechanism is rotatably connected between the two fixed disks. One of the fixed disks has a compression nut at one end, and a compression spring is provided between the fixed disk and the compression nut to elastically adjust the clamping force of the fixed disk. An adjusting sleeve is threadedly connected to the inner side of the compression nut, and the adjusting sleeve is bolted to the output shaft of the dual-shaft gearbox. The adjusting mechanism includes a swing seat, which is rotatably connected to the two fixed disks through an adjusting hollow shaft. The compression nut has a swing limiting groove to limit the rotation angle of the fixed disk. One end of the adjusting hollow shaft is connected to the water distribution regulating valve of the drug supply mechanism.

[0008] Preferably, a matching groove is provided at the overlapping position of the swing seat and the fixed plate.

[0009] Preferably, the inclination angle of the mating groove is 10°, and the swing limiting groove has an inclined surface formed to match the mating groove.

[0010] With this configuration, the swing seat utilizes the mating groove and the adjusting hollow shaft. When the main pipe is resisted by the branches and leaves, causing the swing seat to flip, the inclined surface of the mating groove will be squeezed by the compression nut, causing the compression spring to contract. At this time, the main pipe and the swing seat elastically flip over, thus passing over the branches and leaves. During the reset, the compression spring and the inclined surface are used again to generate an instantaneous reset impact, which beats the branches and leaves, thereby impacting the insects on the branches and leaves.

[0011] Preferably, the swing seat is eccentrically positioned relative to the fixed plate.

[0012] This design, using an eccentric setting, avoids jamming and increases the throwing force during flipping and resetting.

[0013] Preferably, the spraying mechanism includes a main pipe, which is threadedly connected to the channel inside the swing seat. Several spray pipes are evenly distributed on the outer circular end face of the main pipe. The spray pipes are rotatably connected to the main pipe through hollow rods, and nozzles for spraying water are formed on the spray pipes.

[0014] Preferably, the main pipe and the nozzle are made of rubber, and four nozzles are arranged in the same plane in a circular array, with the nozzles being eccentrically positioned.

[0015] With this configuration, the eccentrically positioned nozzle generates a tangential force when the liquid medicine is sprayed out using water pressure, thereby driving the nozzle to rotate and spray the medicine.

[0016] Preferably, the swing amplitude of the swing seat relative to the fixed plate is 0° to 15°.

[0017] Compared with existing technologies, the beneficial effects are as follows:

[0018] 1. By utilizing the rotating mechanism and spraying mechanism on both sides, the original planar spraying method is changed to a vertical rotation method. At the same time, the extended spray pipe increases the coverage of the liquid. It can also spray the vegetation from top to bottom, and during the spraying process, the branches and leaves are moved so that the insects on the upper and lower parts of the branches and leaves are sprayed.

[0019] 2. By coordinating the adjustment mechanism and the spraying mechanism, when spraying and moving the branches and leaves, the reverse resistance of the branches and leaves triggers the adjustment mechanism and the spraying mechanism to flip and swing, thereby knocking the branches and leaves, further improving the spraying effect of the liquid and impacting the insects.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figures 1-9 As shown, a pesticide spraying device for preventing and controlling pests and diseases includes a spraying mechanism 5 for rotating spraying, a rotating mechanism 3, and a dual-shaft gearbox 1 for providing rotational power to the spraying mechanism 5. The rotating mechanism 3 has two parts, which are respectively set on the two output shafts of the dual-shaft gearbox 1. The rotating mechanism 3 has a circular structure. Several adjusting mechanisms 4 for adjusting the state of the spraying mechanism 5 are evenly arrayed on the outer circular end face of the rotating mechanism 3. The spraying mechanism 5 is installed on the adjusting mechanisms 4.

[0035] The rotating mechanism 3 includes two fixed disks 31, and the adjusting mechanism 4 is rotatably connected between the two fixed disks 31. One of the fixed disks 31 is provided with a compression nut 32 at one end. A compression spring 34 is provided between the fixed disk 31 and the compression nut 32 to elastically adjust the clamping force of the fixed disk 31. An adjusting sleeve 33 is threadedly connected to the inner side of the compression nut 32. The adjusting sleeve 33 is bolted to the output shaft of the dual-shaft gearbox 1. The adjusting mechanism 4 includes a swing seat 41. The swing seat 41 is rotatably connected to the two fixed disks 31 through an adjusting hollow shaft 44. The compression nut 32 is provided with a swing limiting groove 42 to limit the rotation angle of the fixed disk 31. One end of the adjusting hollow shaft 44 is connected to the water distribution regulating valve 21 of the drug supply mechanism 2.

[0036] In this embodiment, a mating groove 43 is provided on the swing seat 41 at the overlapping position with the fixed plate 31.

[0037] In this embodiment, the inclined angle of the mating groove 43 is 10°, and the inclined surface of the mating groove 43 is formed in the swing limiting groove 42. The swing seat 41 is mated with the mating groove 43 and the adjusting hollow shaft 44. When the main pipe 51 is resisted by the branches and leaves, causing the swing seat 41 to flip, the inclined surface of the mating groove 43 will be squeezed by the compression nut 32, thereby causing the compression spring 34 to contract. At this time, the main pipe 51 and the swing seat 41 elastically flip over the branches and leaves. When resetting, the compression spring 34 and the inclined surface are used to reset and generate an instantaneous reset impact, which beats the branches and leaves, thereby impacting the insects on the branches and leaves.

[0038] In this embodiment, the swing seat 41 is eccentrically positioned relative to the fixed plate 31. This eccentric positioning avoids jamming and improves the throwing force during flipping and resetting.

[0039] In this embodiment, the spraying mechanism 5 includes a main pipe 51, which is connected to the channel inside the swing seat 41 by a thread. Several spray pipes 52 are evenly distributed on the outer circular end face of the main pipe 51. The spray pipes 52 are rotatably connected to the main pipe 51 by a hollow rod. The spray pipes 52 are formed with nozzles 521 for spraying water.

[0040] In this embodiment, the main pipe 51 and the nozzle 52 are made of rubber. Four nozzles 521 are arranged in the same plane and arranged in a circular array. The nozzles 521 are eccentrically arranged. When the liquid medicine is sprayed out by water pressure using the eccentrically arranged nozzles 521, a tangential force is generated, thereby driving the nozzle 52 to rotate and spray medicine.

[0041] In this embodiment, the swing amplitude of the swing seat 41 relative to the fixed plate 31 is 0° to 15°.

[0042] Working principle: The equipment is moved in the field by a cart or agricultural equipment (the equipment is not shown). The rotating mechanism 3 on both sides corresponds to the branches and leaves on both sides. The pipe of the medicine supply mechanism 2 is connected to the external medicine supply hopper (not shown). The medicine liquid is supplied to the main pipe 51 on both sides through the pipe and the water distribution regulating valve 21 respectively.

[0043] When the equipment moves, the power end of the dual-shaft gearbox 1 is driven to rotate by a motor (not shown). Then, the one-way valve 11 drives the four main pipes 51 to rotate through the adjusting sleeve 33, the squeezing nut 32, and the fixing plate 31. When the pressure of the liquid medicine is sprayed out through the eccentric nozzle 521, the spray pipe 52 rotates, making the spray coverage of the liquid medicine larger. The spray pipe 52, which rotates from the beginning, sprays the liquid medicine from bottom to top, and evenly sprays the lower and upper parts of the branches and leaves, and effectively sprays the insect body.

[0044] When the main pipe 51 is resisted by the branches and leaves, causing the swing seat 41 to flip, the inclined surface of the matching groove 43 will be squeezed by the compression nut 32, causing the compression spring 34 to contract. At this time, the main pipe 51 and the swing seat 41 will elastically flip, thus passing over the branches and leaves. When resetting, the compression spring 34 and the inclined surface will be used again to generate an instantaneous resetting impact, which will beat the branches and leaves, thereby impacting the insects on the branches and leaves.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
