Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a spraying device for plant protection helicopters. Background Technology

[0002] Agricultural helicopters are widely used in agriculture for spraying pesticides and fertilizers on large areas of crops, greatly improving agricultural production efficiency. The spraying device, as the core component of the agricultural helicopter, directly affects the spraying effect and operational quality. Existing agricultural helicopter spraying devices are typically fixed structures, which have several drawbacks in practical use. Firstly, fixed spraying devices occupy a significant amount of space during helicopter transport and storage, increasing transportation costs and storage difficulties. Furthermore, due to their length, they are prone to collisions with surrounding objects during transport, leading to damage and affecting subsequent operational progress. Secondly, when operating in farmland areas with complex terrain and limited space, fixed spraying devices are difficult to adjust their attitude flexibly. This not only fails to achieve the ideal spraying coverage but also makes them susceptible to collisions with obstacles such as trees and utility poles, causing equipment damage and even flight safety accidents. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a spraying device for plant protection helicopters, which solves the technical problems of traditional fixed spraying devices for plant protection helicopters having large space occupation and easy damage during transportation and storage, as well as poor flexibility when operating in complex environments.

[0031] like Figures 1-6 As shown, it illustrates a plant protection helicopter spraying device according to an embodiment of the present invention, including: a mounting plate 1, extension plates 2 rotatably mounted on both sides of the mounting plate 1 via connectors, two sets of first mounting grooves 3 horizontally opened at the bottom end of the mounting plate 1, a first mounting pipe 4 fixedly installed inside each set of first mounting grooves 3, a second mounting groove 5 corresponding to the first mounting groove 3 opened at the bottom end of each set of extension plates 2, a second mounting pipe 6 fixedly installed inside each set of second mounting grooves 5, and several sets of nozzles 7 fixedly installed at the bottom end of each set of first mounting pipes 4 and each set of second mounting pipes 6;

[0032] The movable joint 8 is installed on both sides of each group of first mounting tubes 4. The outer wall of the two groups of second mounting tubes 6 at the same end that are close to each other is provided with external threads 9 that match the movable joint 8.

[0033] For example, such as Figure 3 As shown, slots 10 are provided at both the front and rear ends of the mounting plate 1. A connecting block 11 is fixedly installed at the corresponding position of the slot 10 on each set of extension plates 2. Limiting rods 12 are longitudinally slidably installed at both the front and rear ends of the mounting plate 1. A connecting plate 13 is fixedly installed at the ends of the two sets of limiting rods 12 on the same side that are far apart from each other. A first spring 14 is sleeved on each set of limiting rods 12. The ends of the two sets of first springs 14 on the same side that are close to each other are fixedly connected to the mounting plate 1. The ends of the two sets of first springs 14 on the same side that are far apart from each other are fixedly connected to the connecting plate 13 at the corresponding position. A pull ring 15 is fixedly installed on the outer wall of each set of connecting plates 13. A limiting hole 16 matching the limiting rod 12 is provided on each set of connecting blocks 11.

[0034] For example, such as Figure 4As shown, a storage tank 17 is fixedly installed at the top center of the mounting plate 1. A feed inlet 18 is fixedly installed at the top of the storage tank 17. A pump body 19 is fixedly installed at the bottom inside the storage tank 17. A fixed pipe 20 is sealed to the output end of the pump body 19. A connecting pipe 21 is sealed to the top of each of the two sets of first mounting pipes 4. The other end of each connecting pipe 21 extends into the storage tank 17 and is sealed to the fixed pipe 20. A protective net is fixedly installed inside each set of nozzles 7. The connecting parts are hinges. A connecting bracket 26 is fixedly installed at the top of the mounting plate 1. Support frames 27 are fixedly installed on both sides of the bottom of the mounting plate 1. A battery 28 is fixedly installed at the top of the storage tank 17. A PLC controller 29 is fixedly installed on the right outer wall of the storage tank 17. A signal transceiver 30 is also fixedly installed on the right outer wall of the storage tank 17.

[0035] In some examples, for ease of control, the pump body 19, PLC controller 29, and signal transceiver 30 are all electrically connected to the battery 28, while the signal transceiver 30 is also connected to the ground mobile terminal. When not in operation, the operator can first pull the limiting rod 12 using the pull ring 15, disengaging it from the limiting hole 16 on the connecting block 11. Then, the operator can rotate the extension plate 2 upwards and fold it away, significantly reducing the overall volume of the spraying device, reducing transportation space requirements and storage costs, and minimizing the risk of collision damage during transport. Furthermore, when using the device for operation, the operator can first connect it to the agricultural helicopter using the connecting bracket 26. The assembly is completed, and then the extended plate 2 is unfolded. At the same time, the limiting rod 12 is engaged with the limiting hole 16 at the corresponding position under the action of the first spring 14, so that the unfolded extended plate 2 can be limited and fixed, thereby making the device more stable during use. After the extended plate 2 is unfolded, the operator can connect the movable joint 8 to the external thread 9 on the second mounting pipe 6 at the corresponding position. Then, during operation, the operator can use a mobile terminal to control the pump body 19 through the signal transceiver 30 and PLC controller 29, so that the pesticide stored in the storage box 17 can be pumped into the first mounting pipe 4 and the second mounting pipe 6 through the fixed pipe 20 and the connecting pipe 21, and then sprayed out from the nozzle 7.

[0036] like Figure 6 As shown, a spraying device for a plant protection helicopter is illustrated in another embodiment of the present invention. Spring grooves 22 are longitudinally provided on both sides of the rear end outer wall of the mounting plate 1. U-shaped plates 23 are slidably installed inside the two sets of spring grooves 22. Second springs 24 are fixedly installed inside the two sets of spring grooves 22. The other end of each set of second springs 24 is fixedly connected to the U-shaped plate 23 at the corresponding position. Handles 25 are fixedly installed on the rear end outer wall of the two sets of U-shaped plates 23.

[0037] In some examples, when the device is used in farmland areas with complex terrain and narrow spaces, the operator can plug both ends of the first mounting tube 4 with matching plugs, then fold the extension plate 2 upwards, and then the U-shaped plate 23, under the action of the second spring 24, can keep the top of the extension plate 2 in a limiting position, thereby ensuring the stability of the device when it is in this state.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
