A protective structure for a pesticide sprayer

Abstract

This utility model discloses a protective structure for a pesticide sprayer, including a movable frame and a lifting mechanism. A water tank is fixedly connected to the movable frame, and a second water pipe is connected to the side of the water tank. A protective mechanism is provided on the lifting mechanism. The protective mechanism includes a first water pipe, a first fixing plate, a protective ring, and a rubber telescopic ring. The first fixing plate is fixedly connected to the first water pipe. This protective structure for a pesticide sprayer, by unfolding the protective ring outwards to form a rigid barrier surrounding the nozzle, combined with the elastic buffer of the rubber telescopic ring, can directly prevent fruit tree branches from scraping and impacting the water mist nozzle, thereby preventing nozzle position displacement, blocking impact forces, maintaining the stability of the nozzle's installation angle, increasing the coverage of the target leaves by the spray, reducing pesticide waste, extending the service life of the water mist nozzle, and significantly reducing long-term operating costs.

Description

Technical Field

[0001] This utility model relates to the field of pesticide sprayer technology, specifically a protective structure for pesticide sprayers. Background Technology

[0002] A pesticide sprayer is a device that turns pesticides or other liquids into a mist and sprays them evenly onto objects. It is widely used in agriculture, horticulture, and disease prevention. When using a sprayer in orchards, the pesticide solution needs to be in direct contact with different parasitic locations of different pests and diseases in order to be effective. The absorption capacity of the pesticide solution varies in different parts of the fruit tree, so the spraying focus needs to be adjusted accordingly.

[0003] Existing sprayers include backpack manual sprayers and self-propelled sprayers. Backpack manual sprayers are often used for spraying pesticides in small-scale orchards, while self-propelled sprayers are used for spraying pesticides in large-scale orchards.

[0004] However, fruit tree branches are densely distributed and vary in hardness. When the sprayer moves or operates, the branches easily come into direct contact with the nozzle. During the movement of the frame, the branches are prone to scraping and impacting the nozzle. This scraping and impact can cause the nozzle shell to crack and the spray nozzle to deform. As a result, the nozzle position is offset due to the impact, and the spray direction deviates from the target leaves. This causes the pesticide to be sprayed on the ground and tree trunk, resulting in waste. In addition, flexible debris such as vines and dead leaves can easily get tangled on the nozzle. This tangling can cause the nozzle adjustment parts to jam, lose the function of spray direction adjustment, and fail to evenly cover the leaves, affecting the pest and disease control effect. Frequent nozzle damage requires frequent replacement, increasing consumable costs.

[0005] Therefore, this utility model provides a protective structure for a pesticide sprayer to solve the above problems. Utility Model Content

[0008] The protective mechanism includes a first water pipe, a first fixing plate, a protective ring, and a rubber telescopic ring.

A rotating rod is rotatably connected to the second connecting rod.

[0009] Preferably, the lifting mechanism is mounted on the movable frame, a water pump is mounted on the second water pipe, the second water pipe is mounted on the lifting mechanism, and a valve is mounted on the second water pipe.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figure 1-7 A protective structure for a pesticide sprayer includes a movable frame 1, a lifting mechanism 4, a water tank 2 fixedly connected to the movable frame 1, a second water pipe 6 connected to the side end of the water tank 2, and a protective mechanism provided on the lifting mechanism 4.

[0030] The protective mechanism includes a first water pipe 51, a first fixing plate 52, a protective ring 58, and a rubber telescopic ring 597. The first fixing plate 52 is fixedly connected to the first water pipe 51. A second connecting rod 59 is fixedly connected to the inner side of the protective ring 58. A rotating rod 591 is rotatably connected to the second connecting rod 59.

[0031] The lifting mechanism 4 is mounted on the movable frame 1. A water pump 3 is mounted on the second water pipe 6. The second water pipe 6 is mounted on the lifting mechanism 4. A valve is mounted on the second water pipe 6.

[0032] An electric push rod 54 is fixedly connected to the first fixed plate 52. A second fixed plate 53 is fixedly connected to the end of the electric push rod 54 away from the first fixed plate 52. A sliding groove 55 is provided on the second fixed plate 53. A first connecting rod 56 is slidably connected to the sliding groove 55. The first connecting rod 56 is fixedly connected to the side end of the second connecting rod 59.

[0033] The protective mechanism also includes a movable tube 594, two sets of pulleys 57 are rotatably connected to the first connecting rod 56, the pulleys 57 are located at both ends of the second fixed plate 53, a connecting inner tube 595 is fixedly connected to the inner side of the movable tube 594, and a protective ring 58 is located on the outer side of the movable tube 594.

[0034] A connecting block 593 is fixedly connected to the outside of the moving tube 594, and a limit block 592 is fixedly connected to the outside of the connecting block 593. The end of the rotating rod 591 away from the protective ring 58 is rotatably connected to the connecting block 593.

[0035] The protective mechanism also includes a water mist nozzle 596, a rubber telescopic ring 597 with a neoprene core, the water mist nozzle 596 being connected to the inner tube 595, the rubber telescopic ring 597 being located on the outside of the protective ring 58, and the second fixed plate 53 being slidably connected to the outside of the moving tube 594.

[0036] Working process: Push the mobile frame 1 to place it on the fruit tree to be treated, and then adjust the position of the spray head in conjunction with the lifting mechanism 4.

[0037] Open the valve and start the water pump 3. The solution in the water tank 2 is pumped through the second water pipe 6, the first water pipe 51, the connecting inner pipe 595, and the water mist nozzle 596 in sequence. The solution is then sprayed onto the leaves of the fruit tree using the water mist nozzle 596.

[0038] By activating the electric push rod 54, the distance between the second fixed plate 53 and the first fixed plate 52 is reduced, allowing the first connecting rod 56 to slide on the slide groove 55. The pulley 57 then limits the first connecting rod 56 within the slide groove 55. The first connecting rod 56 slides along the slide groove 55, causing the rotating rod 591 to deflect towards the moving tube 594. This, in turn, causes the protective ring 58 to move outward. The second connecting rod 59, which is embedded inside the limiting block 592, deflects outward, thus protecting the tree branch water mist nozzle 596 from damage by connecting the inner tube 595 and the protective ring 58.

[0039] After the protective ring 58 expands outward, it forms a rigid barrier around the nozzle. Combined with the elastic buffer of the rubber telescopic ring 597, it can directly block the fruit tree branches from scratching and impacting the water mist nozzle 596.

[0040] The three-dimensional protective space formed by the protective ring 58 and the rubber telescopic ring 597 can prevent flexible debris such as leaves and vines from getting tangled on the water mist nozzle 596, thus avoiding the blockage of the nozzle's internal pipes or jamming of the nozzle's adjustment components, ensuring the integrity of the nozzle structure and isolating debris from getting tangled.
