Description

Technical Field

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

[0002] Bananas are an important economic crop widely cultivated in tropical and subtropical regions, and their yield and quality are closely related to pest and disease control. During banana cultivation, regular spraying of pesticides is necessary to effectively suppress fungal, bacterial, and insect infestations; this is a crucial step in ensuring healthy banana growth and increasing yield.

[0003] Currently, pesticide spraying in banana plantations mainly relies on traditional methods. Manual backpack sprayers are commonly used in small banana plantations, but they have significant drawbacks: the operators experience high labor intensity and low work efficiency; the mixing of pesticides largely depends on manually shaking the container, making it difficult to ensure uniformity and easily leading to excessive or insufficient application in certain areas, affecting the control effect; at the same time, the risk of manual contact with pesticides is high, posing safety hazards.

[0004] For larger banana plantations, large motorized spraying equipment is used in some areas. While this improves operational efficiency, the purchase and maintenance costs are high. Furthermore, the complex terrain of banana plantations, such as hilly or mountainous areas, limits its mobility and flexibility, making it difficult to adapt to the operational needs of different plots. In addition, existing spraying devices generally suffer from insufficient mixing of pesticides and fixed spraying angles, making it impossible to accurately adjust the application range according to the characteristics of banana plants at different growth stages, easily leading to pesticide waste. There is also a lack of convenient and effective means for controlling the distribution of pesticides, making it difficult to flexibly regulate the pesticide supply to each spraying unit, further increasing planting costs.

[0005] Therefore, developing a pesticide spraying device for banana cultivation that can balance operational efficiency, application precision, ease of operation, and terrain adaptability has become an urgent problem to be solved in the current banana cultivation field. Utility Model Content

[0037] 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.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figure 1 This utility model provides a pesticide spraying device for banana cultivation, comprising:

[0040] Flatbed cart 1, with a hand-pushing frame 2 installed on the top of flatbed cart 1;

[0041] Mixing tank 3 is fixed on the top surface of flatbed truck 1. A lid 4 is installed on the top surface of mixing tank 3, and a water injection hole is opened on the lid 4.

[0042] A stirring assembly is installed on the lid 4 and extends into the mixing tank 3 for mixing the medicine solution;

[0043] Distributor 5 is installed on the top of the flatbed truck 1. The feed end of distributor 5 is connected to the bottom side of the mixing tank 3 through a connecting pipe, and a water pump is installed on the connecting pipe.

[0044] The spraying mechanism includes a boom 6 symmetrically and rotatably connected to the top surface of the flatbed 1. Several nozzles 7 are fixed at equal intervals on the boom 6. The nozzles 7 are connected to the distributor 5 through a conveying pipe. An angle adjustment component is installed at the bottom of the flatbed 1. The angle adjustment component is rotatably connected to the two sets of booms 6.

[0045] The controller, stirring assembly, water pump, and angle adjustment assembly are respectively connected to the controller;

[0046] Manual valves are installed on the delivery pipes.

[0047] In operation, this invention adds a measured amount of water and pesticide to the mixing tank 3 through the water injection hole on the top cover 4. Then, the controller activates the stirring assembly, which extends into the mixing tank 3 and rotates at high speed to thoroughly mix the water and pesticide, forming a uniform solution and preventing localized excessively high or low concentrations of the pesticide. After mixing, the controller activates the water pump on the connecting pipe, which pumps the solution from the bottom of the mixing tank 3 into the distributor 5. The distributor 5 distributes the solution through the delivery pipe to several nozzles 7 on the boom 6. A manual valve on the delivery pipe allows manual control of the on / off state of individual or group nozzles 7 as needed. Depending on the spraying target (leaves, stems, etc.), the controller controls the angle adjustment assembly at the bottom of the flatbed trolley 1. This assembly, connected to the boom 6, rotates two symmetrical booms 6 around a pivot point on the top of the flatbed trolley 1, thereby adjusting the tilt angle of the nozzles 7 to ensure precise spraying of the pesticide to the target location. By pushing the hand-operated frame 2 of the flatbed cart 1, the device is moved in the banana planting field, while the nozzle 7 atomizes and sprays the pesticide. Combined with the angle adjustment and manual valve control, comprehensive and precise spraying of the banana plants can be achieved.

[0048] The design has been further optimized, and the stirring components include:

[0049] The stirring motor 8 is fixed to the top surface of the bucket lid 4;

[0050] The stirring shaft is fixed on the output shaft of the stirring motor 8, and one end of the stirring shaft extends into the mixing tank 3. The axis of the stirring shaft is coaxial with that of the mixing tank 3, and several stirring teeth are fixed on the outer wall of the stirring shaft.

[0051] The stirring motor 8 is fixed on the top surface of the bucket cover 4. After the power is turned on, the motor output shaft rotates and drives the coaxial stirring shaft to rotate synchronously. The stirring shaft is arranged along the central axis of the mixing bucket 3. Several stirring teeth on its outer wall rotate at high speed with the shaft. The teeth cut and stir the water and medicine in the mixing bucket 3. Since the stirring shaft is coaxial with the mixing bucket 3, the stirring teeth can evenly cover the radial space inside the bucket, avoid mixing dead corners, and ensure that the medicine is fully mixed under the action of rotational shear force.

[0052] Further optimization of the solution includes the following angle adjustment components:

[0053] Adjust motor 9, which is fixed to the bottom of flatbed 1;

[0054] Speed ​​controller, the speed controller is fixed at the bottom of the flatbed 1, and the output shaft of the regulating motor 9 is connected to the input shaft of the speed controller;

[0055] Turntable 10 is coaxially fixed on the output shaft of the speed controller;

[0056] An eccentric shaft 11 is fixed on a turntable 10, and the axis of the eccentric shaft 11 is arranged parallel to the axis of the turntable 10.

[0057] The turning rod 12 has a V-shaped structure. A fixed seat is fixedly connected to the bottom of the flatbed 1. The middle position of the turning rod 12 is rotatably connected to the fixed seat. A clearance groove is provided on the flatbed 1. One end of the turning rod 12 extends into the clearance groove. A connecting rod 13 is rotatably connected to the bottom of the turning rod 12. One end of the connecting rod 13 is rotatably connected to the eccentric shaft 11.

[0058] The first tie rod 14 has one end rotatably connected to the middle position of one of the booms 6, and the other end rotatably connected to the bottom of the turning rod 12.

[0059] The second tie rod 15 has one end rotatably connected to the middle position of another set of booms 6, and the other end rotatably connected to the top of the turning rod 12.

[0060] The power output of motor 9 is adjusted and transmitted to turntable 10 after the speed is adjusted by the speed regulator, so that turntable 10 rotates at a set speed. When the eccentric shaft 11 on turntable 10 rotates with turntable 10, because the axis is not concentric with turntable 10, it drives connecting rod 13 to perform reciprocating push-pull motion. Connecting rod 13 pushes turning rod 12 (V-shaped structure) to swing around the rotation point of fixed seat (lever principle): when the bottom of turning rod 12 is pushed, the top swings in the opposite direction. The two ends of turning rod 12 pull two sets of symmetrical booms 6 through the first pull rod 14 and the second pull rod 15 respectively, so that booms 6 rotate synchronously in opposite directions around the rotation point of the top surface of flatbed 1 (e.g., one boom 6 tilts upward and the other tilts downward), thereby accurately adjusting the spray angle of nozzle 7. The speed regulator can control the speed of turntable 10 and indirectly adjust the rate of change of boom angle to adapt to different operating needs (e.g., fast coarse adjustment or slow fine adjustment).

[0061] To further optimize the design, a long groove is provided on the side of the mixing tank 3, and a transparent observation window is installed in the long groove. The transparent observation window is equipped with scale lines 16 for observing the liquid level.

[0062] A transparent observation window (such as an acrylic plate) is installed in the long groove on the side of the mixing tank 3. Its light transmission allows the operator to directly observe the liquid level in the tank. The scale line 16 on the observation window is marked with the volume unit (such as liter). When adding water or chemicals, the amount added can be accurately controlled by the alignment of the liquid level with the scale, so as to avoid the spraying efficiency being affected by too much or too little liquid.

[0063] The design has been further optimized by installing a buffer handle 17 on the push frame 2.

[0064] The design was further optimized by installing a water injection pipe 18 on the water injection hole, and a switch control valve on the water injection pipe 18.

[0065] Water injection pipe 18 connects to water injection hole, connecting external water source (such as water pipe) to mixing tank 3, guiding water flow into a specific direction to avoid spillage when adding water; the switch control valve (such as ball valve or gate valve) on water injection pipe 18 can control the opening and closing of the pipeline and the water flow by rotating the handle, making it easy to adjust the water injection volume as needed (such as rapid water addition or slow water replenishment), and to achieve quantitative water injection in conjunction with the observation window scale, thereby improving operating efficiency.

[0066] In this embodiment, the controller model needs to be selected according to actual needs.
