Description

Technical Field

[0001] The present invention relates to the technical field of pesticide spraying equipment, and specifically refers to a portable fruit tree pesticide spraying machine. Background Art

[0002] During the process of fruit tree planting, pest control is a key link to ensure the healthy growth of fruit trees and increase fruit yield. Traditional fruit tree spraying methods mainly rely on manual backpack sprayers or tractor-drawn sprayers. However, there are many problems in the application of these two methods:

[0003] Manual backpack sprayer:

[0004] High labor intensity: Operators need to carry heavy liquid medicine tanks and spraying equipment, and long-term operation is likely to cause fatigue, affecting work efficiency and spraying quality.

[0005] Limited coverage: Due to the limited spraying distance and coverage of the sprayer, for tall fruit trees or orchards with high planting density, the spraying effect is not good, and there is likely to be missed spraying or uneven spraying.

[0006] Liquid medicine waste: It is difficult to accurately control the liquid medicine spraying amount by manual operation, which is likely to cause liquid medicine waste and increase planting costs.

[0007] Tractor-drawn sprayer:

[0008] Poor flexibility: The equipment is large in size, difficult to operate flexibly between narrow fruit tree rows, and has high requirements for orchard terrain.

[0009] High cost: The equipment purchase cost and maintenance cost are relatively high, and for small and medium-sized orchards, the economy is poor.

[0010] Damage to fruit trees: The equipment is likely to cause mechanical damage to fruit trees during operation, affecting the growth of fruit trees.

[0011] With the expansion of fruit tree planting scale and the popularization of the concept of precision agriculture, the market has put forward higher requirements for efficient, convenient and intelligent fruit tree spraying equipment. In recent years, some new types of fruit tree spraying equipment have gradually emerged, such as:

[0012] Self-propelled orchard sprayer:

[0013] It has a certain degree of automation and can realize automatic walking and spraying, but the equipment structure is complex, the cost is relatively high, and its adaptability to orchard terrain is poor.

[0014] Drone spraying:

[0015] It has developed rapidly in recent years and has advantages such as high spraying efficiency and wide coverage, but there are the following problems:

[0016] Complicated operation: Professional personnel are required for operation and training.

[0017] Liquid medicine drift: Under the influence of wind, it is easy to cause liquid medicine drift, resulting in environmental pollution and reduced drug efficacy.

[0018] High cost: The equipment purchase cost and maintenance cost are relatively high.

[0019] Currently, the existing spraying equipment mainly has the following problems in the field of fruit tree spraying:

[0020] 1. Lack of operation convenience:

[0021] Most of the existing equipment has complicated operations and requires professional training to master proficiently, which affects the popularization and use efficiency of the equipment.

[0022] 2. Poor spraying effect:

[0023] Problems such as uneven spraying, insufficient coverage, and low liquid medicine adhesion rate are common, resulting in unsatisfactory pest control effects.

[0024] 4. Poor equipment adaptability:

[0025] It is difficult to adapt to the orchard operation requirements of different terrains and different planting modes, which limits the application range of the equipment.

[0026] 5. Serious liquid medicine waste:

[0027] The existing equipment has insufficient control accuracy of the liquid medicine, which is easy to cause liquid medicine waste and increase the planting cost.

[0028] Therefore, a portable fruit tree spraying machine is proposed to solve the existing deficiencies. Summary of the Invention

[0029] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a portable fruit tree spraying machine.

[0030] To solve the above technical problems, the technical solution provided by the present invention is a portable fruit tree spraying machine: including a housing, a blower, and a spraying part;

[0031] The housing is integrally in a hollow cylindrical structure with one end open. A handheld part is provided at the rear end of the housing. A blower is provided in the rear part of the housing. The blower is connected to an air duct extending to the front end of the housing. The spraying part is arranged at the front end in the housing. A medicine delivery pipe extending along the housing and connected to the spraying part is provided in the handheld part. A handle switch cooperating with the medicine delivery pipe is provided on the inner side of the handheld part. A travel switch cooperating with the tail end of the handle switch is provided in the handheld part. A control board is provided at the rear end in the housing;

[0032] It also includes an external power supply, which is connected to the travel switch through a power cord. Both the blower and the travel switch are electrically connected to the control board.

[0033] As an improvement, the front end of the housing is in a horn-shaped structure, and the rear end of the housing is provided with heat dissipation holes.

[0034] As an improvement, the spraying part is arranged at the front end of the housing and in front of the air duct. The spraying part includes a medicine distribution ring and spraying nozzles. The medicine distribution ring is fixedly connected to the housing, and the number of the spraying nozzles is multiple and they are arranged circumferentially along the axis of the medicine distribution ring.

[0035] As an improvement, the spraying nozzles are arranged circumferentially along the housing, and their spraying ports face the end away from the blower.

[0036] As an improvement, it also includes a speed regulator, which is arranged near the handheld part of the housing and is electrically connected to the control board.

[0037] As an improvement, a connector connected to the medicine delivery pipe is provided at the rear end of the handheld part.

[0038] The advantages of the present invention compared with the prior art are as follows:

[0039] 1. The handle switch and the travel switch are integrated in the handheld part. The operator can complete the operation with only one hand. The linkage between the travel switch and the handle switch can simultaneously control the on-off of the medicine delivery pipe and the start-stop of the blower through one action, realizing the automatic control of the spraying process, effectively simplifying the operation process, reducing the labor intensity of the operator, and improving the operation convenience.

[0040] 2. The spraying part is located at the horn-shaped structure at the front end of the housing, and the uniform distribution and atomization of the liquid medicine are realized through the medicine distribution ring and multiple spraying nozzles. The high-speed airflow generated by the blower is fully mixed with the liquid medicine sprayed from the spraying nozzles to form a uniform atomized spray, which can generate finer droplets, improve the liquid medicine coverage range and adhesion rate. At the same time, the horn-shaped structure design at the front end of the housing effectively diffuses the airflow and the liquid medicine, and uses the high-speed airflow generated by the blower to penetrate the fruit tree canopy layer. The airflow penetration power is stronger, which can ensure that the liquid medicine reaches the back of the leaves, branches and other parts, improving the spraying effect.

[0041] 3. The structure of this spraying machine is designed compactly, with light weight, convenient to carry and operate. It can realize efficient, accurate and convenient fruit tree spraying operations. While improving the spraying effect, it effectively reduces the labor intensity and liquid medicine waste, and is suitable for use in orchards with various terrains and planting modes, having significant technical advantages and practical values.

[0050] To make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the invention. Apparently, the described embodiments are some, but not all, of the embodiments of the invention. Components of the embodiments of the invention described and illustrated herein generally may be arranged and designed in a variety of different configurations.

[0051] In the description of the embodiments of the invention, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed during use. It is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0052] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the components are required to be absolutely horizontal or hanging, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0053] In the description of the embodiments of the invention, "a plurality of" represents at least two.

[0054] In the description of the embodiments of the invention, it should also be noted that unless otherwise clearly specified and limited, if the terms "set", "installed", "connected", "connected" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific situations.

[0055] As shown in the accompanying drawings, a portable fruit tree spraying machine includes a housing 1, a blower 2, and a spraying part 3;

[0056] The housing 1 is integrally in a hollow cylindrical structure with an open end at one side, providing sufficient space to accommodate the blower 2 and other internal components. At the same time, the hollow structure also reduces the overall weight of the machine, making it convenient for the operator to hold and use.

[0057] The front end of the housing 1 is in a horn-shaped structure, which can effectively disperse the air flow and the liquid medicine, improving the coverage range. At the same time, by using the air flow of the blower to penetrate the fruit tree canopy, the adhesion rate of the liquid medicine is enhanced.

[0058] The horn-shaped structure at the front end of the housing 1 can disperse the high-speed air flow generated by the blower 2, so that the air flow uniformly expands from the narrow outlet of the air duct 5 to a wider area, increasing the spraying coverage area. Furthermore, it plays a role in dispersing the liquid medicine sprayed from the spraying part 3, making the liquid medicine evenly dispersed under the action of the air flow, forming a larger spraying range, thereby improving the coverage range of the fruit tree canopy.

[0059] At the same time, the horn-shaped structure at the front end of the housing 1 helps to concentrate the energy of the air flow, enabling it to penetrate the fruit tree canopy more effectively, ensuring that the liquid medicine can reach deeper into the fruit tree, and improving the adhesion rate of the liquid medicine on parts such as leaves and branches.

[0060] In this embodiment, after the air flow generated by the blower 2 is dispersed through the horn-shaped front end of the housing 1, it is fully mixed with the liquid medicine sprayed from the spraying part 3, not only improving the atomization effect of the liquid medicine, but also enhancing the penetration and adhesion rates of the liquid medicine in the fruit tree canopy.

[0061] At the same time, through the diffusion effect of the air flow and the liquid medicine, and the enhanced penetration, a more uniform and comprehensive spraying effect can be achieved, improving the utilization rate of pesticides and reducing the waste of liquid medicine.

[0062] The rear end of the housing 1 is provided with heat dissipation holes 11. In this embodiment, the heat dissipation holes 11 help the blower dissipate heat, prevent the motor from overheating, and extend the service life.

[0063] The rear end of the housing 1 is provided with a handheld part 4, which is convenient for the operator to hold and use for a long time.

[0064] A blower 2 is provided at the rear part inside the housing 1. The blower 2 is connected with a wind tube 5 extending to the front end of the housing 1. The wind tube 5 forms an air flow channel to guide the air flow to accurately reach the spraying part 3 and work together with the spraying part 3 to provide air flow power for the atomized spraying of the liquid medicine.

[0065] Specifically, the high-speed air flow generated by the blower 2 is transmitted to the spraying part 3 through the wind tube 5. At the spraying part 3, the air flow meets the liquid medicine ejected from the spraying nozzle 32. The high-speed air flow generates a shear force on the liquid medicine, breaking the liquid medicine into fine droplets to form a fog-like spray. The air flow carries the atomized liquid medicine and sprays it forward. While expanding the spraying range, it penetrates the fruit tree canopy layer to achieve effective spraying of the fruit trees.

[0066] The spraying part 3 is arranged at the front end inside the housing 1, that is, the spraying part 3 is located at the horn-shaped structure at the front end of the housing 1. Through cooperation with the blower 2, the air flow of the blower blows the liquid medicine out from the front end of the housing 1 to form an atomized spray, enhancing the penetrability of the fruit tree canopy layer.

[0067] Specifically, the spraying part 3 is arranged at the front end of the housing 1 and in front of the wind tube 5, which can ensure that when the liquid medicine leaves the spraying nozzle 32, it can be fully mixed with the high-speed air flow generated by the blower 2 to achieve a better atomization effect.

[0068] The spraying part 3 includes a medicine distribution ring 31 and spraying nozzles 32. The medicine distribution ring 31 is fixedly connected with the housing 1. The number of the spraying nozzles 32 is multiple and they are arranged circumferentially along the axis of the medicine distribution ring 31. The circumferentially distributed spraying nozzles 32 can form a uniform atomized spray.

[0069] Furthermore, the spraying nozzles 32 are arranged circumferentially along the housing 1 and their spraying ports face away from the blower 2, which can avoid the high-speed air flow directly impacting the spraying nozzles 32 and affecting the stability of the liquid medicine spraying. At the same time, it also helps the liquid medicine to be sprayed forward under the drive of the air flow to form a longer spraying distance.

[0070] Moreover, during implementation, the multiple spraying nozzles 32 are circumferentially and evenly distributed, which can form a 360-degree full-coverage spraying mode, ensuring uniform liquid medicine spraying, a wide coverage range, and enabling the liquid medicine to be evenly covered on the fruit tree canopy layer, effectively avoiding spraying dead angles and improving the spraying efficiency.

[0071] A liquid medicine delivery pipe 6 extending along the housing 1 and connected with the spraying part 3 is arranged inside the handheld part 4 for delivering the liquid medicine.

[0072] During implementation, the medicine delivery tube 6 extends along the inside of the housing 1, making full use of the space inside the housing 1, avoiding the inconvenience brought by external pipelines. At the same time, placing the medicine delivery tube 6 inside the housing 1 can effectively protect the liquid medicine pipeline from being damaged by the external environment.

[0073] Furthermore, a connector 13 connected to the medicine delivery tube 6 is provided at the rear end of the handheld part 4, facilitating connection to an external medicine supply device through a hose to achieve the delivery of liquid medicine.

[0074] During operation, it is convenient for the operator to connect and disconnect the hose, and at the same time, it will not interfere with the holding and use of the handheld part 4.

[0075] A handle switch 7 cooperating with the medicine delivery tube 6 is provided inside the handheld part 4 for controlling the conduction and closing of the medicine delivery tube 6.

[0076] During operation, by operating the handle switch 7, the medicine delivery tube 6 can be opened or closed, thereby controlling the delivery of liquid medicine, enabling the operator to start or stop spraying at any time, improving the flexibility and safety of operation.

[0077] During specific implementation, an external medicine supply device (such as a liquid medicine barrel, a liquid medicine pump, etc.) is connected to the connector 13 through a hose.

[0078] Under the action of the external medicine supply device (such as pumping), the liquid medicine enters the medicine delivery tube 6 through the connector 13, and the delivery of the liquid medicine is controlled by opening the handle switch 7. The medicine delivery tube 6 delivers the liquid medicine to the spraying part 3.

[0079] A travel switch 9 cooperating with the tail end of the handle switch 7 is provided inside the handheld part 4. The handle switch 7 is linked with the travel switch 9. By pressing, the conduction of the medicine delivery tube 6 for delivering medicine and the start of the blower 2 are triggered. The operation is convenient. During operation, the operator only needs one action (press the handle switch 7) to start the spraying and air supply functions simultaneously.

[0080] A control board 10 is provided at the rear end inside the housing 1 to achieve the control of the operation of this medicine spraying machine.

[0081] It also includes an external power supply 8. The external power supply 8 is connected to the travel switch 9 through a power cord to provide power support for this medicine spraying machine.

[0082] The blower 2 and the travel switch 9 are both electrically connected to the control board 10.

[0083] It also includes a speed regulator 12. By changing the wind speed through the speed regulator, it can adapt to different fruit tree heights and densities, achieving flexible adjustment of the wind speed;

[0084] The speed regulator 12 is arranged near the handheld part 4 of the housing 1. The speed regulator 12 is electrically connected to the control board 10 to achieve the adjustment of the wind speed.

[0085] In this embodiment, the fan 2 is a fan with the model number NMB-MAT 4715KL-04W-B10, the control board 10 is a microcontroller of Arduino Nano, the travel switch 9 is a micro roller lever switch with the model number KW11-3Z, the speed regulator 12 is a speed regulator with the model number L298N, and the external power supply 8 is a rechargeable lithium battery pack of 12V 10Ah.

[0086] The present invention and its embodiments have been described above. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
