Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, and in particular to a pesticide spraying device for nut cultivation. Background Technology

[0002] In nut cultivation, pesticide spraying is a crucial step in ensuring healthy fruit growth. Nut trees are susceptible to pests such as aphids, spider mites, and scale insects, as well as diseases like powdery mildew and anthracnose. Proper pesticide application can effectively suppress the spread of pests and diseases, reducing problems such as leaf drop and fruit deformities. It is essential to seize the optimal spraying time, generally at the early stages of pest and disease outbreaks or during critical growth periods (such as flowering and fruit setting). During spraying, the pesticide should be evenly applied to both sides of the leaves, branches, and the surface of the fruit to ensure thorough contact with the target area, thereby enhancing control effectiveness and laying the foundation for high-quality and high-yield nuts.

[0003] In existing technologies, pesticides in the pesticide tank may settle to the bottom during spraying, resulting in poor spraying quality. Some spraying devices with stirring mechanisms rely on independent electric motors or fuel engines, requiring additional electricity or fuel consumption. Therefore, we propose a pesticide spraying device for nut cultivation. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide spraying device for nut cultivation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pesticide spraying device for nut cultivation, comprising a frame and an anti-sinking mechanism mounted on top, wherein a spraying mechanism is also mounted on top of the frame, and the anti-sinking mechanism comprises two sets of auxiliary wheels, each set of auxiliary wheels being connected to a chain and a synchronous wheel via gears, and connecting rods being fixedly installed on the inner sides of each set of synchronous wheels, the two sets of connecting rods being connected to a worm gear via worm shafts, and the worm gear being connected to a stirring blade via a stirring shaft.

[0007] As a preferred embodiment, the two sets of auxiliary wheels are rotatably connected to the two sides of the frame near the front end, the gear is fixedly installed on the outer wall of the auxiliary wheel, one end of the chain meshes with the gear, and the other end of the chain meshes with the synchronous pulley. Connecting plates are fixedly connected to both sides of the upper end of the medicine canister, and the two sets of connecting rods are rotatably connected inside the connecting plates.

[0008] As a preferred embodiment, the worm gear is fixedly installed in the middle of the two sets of connecting rods, the worm wheel is meshed with the worm gear, the lower end of the worm wheel is rotatably connected to the upper end of the medicine tank, the stirring shaft is fixedly installed at the lower end of the worm wheel, and the stirring blade is fixedly installed on the outer wall of the stirring shaft.

[0022] 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.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 A pesticide spraying device for nut cultivation includes a frame 1 and an anti-sinking mechanism 5 mounted on top. A spraying mechanism 6 is also mounted on top of the frame 1. The anti-sinking mechanism 5 includes two sets of auxiliary wheels 501. Both sets of auxiliary wheels 501 are connected to a chain 503 and a synchronous pulley 504 via gears 502. Connecting rods 506 are fixedly installed on the inner sides of both sets of synchronous pulleys 504. The two sets of connecting rods 506 are connected to a worm wheel 508 via a worm gear 507. The worm wheel 508 is connected to a stirring blade 510 via a stirring shaft 509.

[0024] A medicine tank 2 is fixedly installed on the upper end of the frame 1. A water pump 3 is fixedly installed on the water outlet pipe of the medicine tank 2. The bottom of the water pump 3 is fixedly installed on the surface of the frame 1. Drive wheels 4 are provided on both sides of the frame 1 near the rear end.

[0025] Two sets of auxiliary wheels 501 are rotatably connected to the two sides of the frame 1 near the front end. Gears 502 are fixedly installed on the outer wall of the auxiliary wheels 501. One end of the chain 503 meshes with the gear 502, and the other end of the chain 503 meshes with the synchronous pulley 504. Connecting plates 505 are fixedly connected to both sides of the upper end of the medicine tank 2. Two sets of connecting rods 506 are rotatably connected inside the connecting plates 505.

[0026] The two sets of auxiliary wheels 501 are synchronously connected through the connecting plate 505 to ensure consistent power transmission on both sides and avoid insufficient mixing caused by uneven force on one side.

[0027] The worm 507 is fixedly installed in the middle of the two sets of connecting rods 506. The worm wheel 508 is meshed with the worm 507. The lower end of the worm wheel 508 is rotatably connected to the upper end of the medicine tank 2. The stirring shaft 509 is fixedly installed at the lower end of the worm wheel 508. The stirring blade 510 is fixedly installed on the outer wall of the stirring shaft 509.

[0028] By utilizing the meshing characteristics of the worm gear 508 and the worm 507, the high-speed rotation of the auxiliary wheel 501 is converted into the low-speed, high-torque rotation of the stirring shaft 509, so that the stirring blade 510 can obtain sufficient power to fully stir the pesticide. The self-locking characteristic of the worm gear 508 and worm 507 transmission can prevent the stirring shaft 509 from reversing due to the sloshing of the pesticide when the device stops moving, thus maintaining the stability of stirring.

[0029] Specifically, the auxiliary wheel 501 at the front of the frame 1 rolls in contact with the ground, and the power is transmitted to the worm gear 507 through the gear 502, chain 503 and synchronous pulley 504. This drives the worm wheel 508 to rotate the mixing shaft 509 and the mixing blade 510. No additional electricity or engine is required to drive it, so it can mix while walking. This effectively prevents pesticide sedimentation in the pesticide tank 2 and ensures uniform spray concentration. Compared with traditional electric or fuel-powered mixing devices, it reduces energy consumption and conforms to the concept of green agriculture.

[0030] Please see the appendix Figure 1 and attached Figure 5 - Appendix Figure 7 The spraying mechanism 6 includes two sets of hydraulic telescopic rods 601 and a water inlet pipe 606. The bottom of the two sets of hydraulic telescopic rods 601 is fixedly installed on the upper end of the frame 1. The upper end of the two sets of hydraulic telescopic rods 601 is fixedly installed with a bracket 602. The inside of the bracket 602 is fixedly installed with a fixing rod 603 near both sides. The outer wall of the fixing rod 603 is rotatably connected with a rotating frame 604.

[0031] Both the rotating frame 604 and the bracket 602 are fixedly installed with buckles 605. One end of the water inlet pipe 606 is fixedly installed at the outlet of the water pump 3, and the other end of the water inlet pipe 606 is fixedly connected to a hose 607. The hose 607 is snapped into the inside of the buckle 605, and multiple sets of nozzles 608 are opened on the outer wall of the hose 607.

[0032] During operation, the rotating frame 604 can be rotated out from the support 602 to expand the spraying range. When encountering obstacles such as tree trunks, field ridges, or when passing through narrow areas, the rotating frame 604 can be quickly folded to improve the equipment's mobility.

[0033] Specifically, the hydraulic system adjusts the height of the hydraulic telescopic rod 601, allowing for flexible adjustment of the spraying height of the nozzle 608 according to different growth stages of nut trees, such as seedlings and mature trees, to achieve precise application of pesticides. The rotating frame 604 can be rotated and retracted into the support 602, significantly reducing the lateral space occupied by the device in non-operational states such as transportation and storage, facilitating movement in narrow orchard passages or field paths, and also reducing the space requirements for warehouse storage.

[0034] The working principle of this utility model is as follows: This utility model is a pesticide spraying device for nut planting. The prepared pesticide is added into the pesticide tank 2. The rotating frame 604 rotates out from the inside of the support 602 around the fixed rod 603. The height of the support 602 is adjusted by the hydraulic telescopic rod 601 so that the nozzle 608 is aimed at the fruit tree spraying area.

[0035] The drive wheel 4 drives the frame 1 to move within the orchard. At the same time, the two sets of auxiliary wheels 501 at the front end of the frame 1 roll and rotate with the ground. When the auxiliary wheels 501 rotate, they drive the chain 503 through the gear 502 on the outer wall. The chain 503 drives the synchronous wheel 504 to rotate. The two sets of synchronous wheels 504 are kept in sync through the connecting plate 505. The connecting rod 506 on the inner side drives the worm gear 507 to rotate.

[0036] The worm gear 507 meshes with the worm wheel 508 for transmission. The worm wheel 508 drives the stirring shaft 509 at the lower end to rotate, so that the stirring blade 510 continuously stirs the medicine liquid in the medicine tank 2 to prevent sedimentation.

[0037] Start the water pump 3. The liquid medicine in the medicine tank 2 enters the water pump 3 through the water outlet pipe, and then is delivered to the hose 607 through the water inlet pipe 606. Under pressure, the liquid medicine is sprayed out from the multiple sets of nozzles 608 on the outer wall of the hose 607 to spray the nut trees. The buckle 605 fixes the position of the hose 607 to prevent it from shaking and deviating from the target area during the spraying process.

[0038] When encountering obstacles such as tree trunks or field ridges, the rotating frame 604 is rotated back into the support 602 around the fixed rod 603 to reduce the lateral width. If necessary, the height of the support 602 is lowered by the hydraulic telescopic rod 601 to ensure that the frame 1 passes smoothly.

[0039] After spraying is completed, turn off the power to the drive wheel 4, retract the rotating frame 604 completely into the bracket 602, lower the bracket 602 to the lowest position using the hydraulic telescopic rod 601, clean the residual liquid in the tank 2 and pipeline, and check whether each component such as the nozzle 608, chain 503 and stirring blade 510 is intact in preparation for the next operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
