Description

Technical Field

[0001] This utility model relates to the field of orchard planting technology, specifically to an orchard multi-duct air-assisted sprayer / powderer. Background Technology

[0002] Pest and disease control and pollination are crucial aspects of fruit tree management. Currently, during orchard pesticide application, less than 30% of pesticides effectively adhere to the target tree canopy, with the majority drifting above, below, and between the canopies. To address this issue, domestic and international research institutions and companies have developed various spraying technologies in recent years, including variable displacement spraying, wind-assisted spraying, contour spraying, targeted spraying, and droplet drift control, achieving good pest and disease control results. However, the plant protection machinery currently used in orchards is still mainly the disc-type wind-assisted sprayer. This type of equipment cannot deliver spray in a directional manner, causing some airflow to carry droplets and drift away. Multi-duct wind-assisted spraying technology is a type of wind-assisted spraying technology. By precisely adjusting and controlling the direction and angle of each duct, it achieves targeted airflow delivery, helping to reduce pesticide waste and obtain better application results.

[0003] Most fruit trees require cross-pollination, and currently, the main assisted pollination technique is manual pollination, which is inefficient and labor-intensive. Mechanical pollination also lacks specialized and efficient pollination machinery.

[0004] To address the problems of severe pesticide drift in orchards and the lack of specialized pollination machinery, a multi-duct air-assisted sprayer / duster integrated machine for orchards is proposed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated orchard multi-duct air-assisted spraying and dusting machine. The air-assisted spraying system can be used for the prevention and control of orchard pests and diseases, as well as for liquid pollination of fruit trees by spraying pollen solution. The air-assisted dusting system can also be used for dry powder spraying, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-duct air-assisted sprayer / powderer for orchards, comprising a chassis, a frame fixedly mounted on the top surface of the chassis, a medicine tank fixedly mounted on the frame, a liquid pump connected to the medicine tank, a flexible hose connected to the frame, and a tower fan connected to the flexible hose.

[0025] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0026] A preferred embodiment of the orchard multi-duct air-assisted sprayer / powderer provided by this utility model is as follows: Figures 1 to 7 As shown: A multi-duct air-assisted sprayer / powderer for orchards includes a chassis 3, a frame 6 fixedly mounted on the top surface of the chassis 3, a medicine tank 1 fixedly mounted on the frame 6, a liquid pump 2 connected to the medicine tank 1, and flexible hoses 4 connected to the frame 6. There are multiple flexible hoses 4, and each flexible hose 4 has a nozzle 5 connected to its end. A motor 12 is installed at the nozzle 5, and a brush 11 is installed at the output end of the motor 12. A powder bottle 10 is installed at the nozzle 5 through a powder spraying screw 8. A double-spiral mixing baffle 9 is also installed at the nozzle 5. A tower fan 7 is connected to the flexible hose 4.

[0027] The frame 6 includes a main support arm 61, an extension arm 62, and a working component bearing area 63. The main support arm 61 is fixedly installed with the extension arm 62 and the working component bearing area 63. There are multiple extension arms 62, and each extension arm 62 is fixedly installed with the outer wall of the flexible hose 4. There are multiple working component bearing areas 63, and each working component bearing area 63 is fixedly installed with the medicine tank 1 and the liquid pump 2 respectively.

[0028] The tower fan 7 includes a tower plate 71, which is fixedly installed on the side of the chassis 3. A fan cover 76 is fixedly installed on the tower plate 71. The fan cover 76 has a guide plate 72, a fan blade 73, and an air outlet 74 inside. A fan guide cover 75 is installed at the end of the fan cover 76.

[0029] Working principle: The orchard multi-duct air-assisted sprayer / powderer works in concert with the air delivery system and the spraying system, as well as the air delivery system and the powder spraying system. The air delivery system uses a tower fan 7, which can effectively guide the airflow to a certain height. Five outlet air ducts are symmetrically distributed on each side of the tower cavity. Ten flexible hoses are used to construct a ten-duct air delivery system. The guide plate inside the cavity further optimizes the airflow field to ensure that the airflow at the ten outlets is relatively evenly distributed.

[0030] The spray system is equipped with a duckbill-shaped air nozzle (5), with an inlet diameter of 120mm, a duckbill section length of 100mm, and an outlet groove length of 220mm, width of 15mm, and wall thickness of 2mm. It is paired with a TR-80-02 hollow cone mist nozzle, allowing for easy switching between nozzle types and spray spacing to ensure uniform pesticide application. Furthermore, this nozzle is interchangeable with a mixing nozzle for powder spraying, enabling flexible switching between spray and powder spraying modes.

[0031] The powder spraying system has a semi-circular inner convex thread double spiral air mixing baffle 9 at the front end of the structure, which transforms laminar airflow into turbulent flow, enhances pollen dispersion, changes the airflow force structure, and makes the airflow distribution more uniform. The powder spraying structure ensures that the powder is sprayed evenly during operation.

[0032] The nozzle is interchangeable with the spray nozzle, enabling one machine to perform multiple functions such as spraying and dusting. The entire equipment works closely together through various systems to adapt to different plant protection and pollination needs in orchards, improving operational efficiency and effectiveness.
