Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, specifically to an air intake guide mechanism for orchard wind-driven spray equipment. Background Technology

[0002] The core principle of orchard wind-driven spraying equipment is the synergistic effect of precise atomization of pesticide liquid and high-speed airflow delivery. Through power drive, it achieves atomization, delivery, and uniform coverage of the pesticide liquid. The application of pesticides is completed through the cooperation of two core systems: first, the pesticide liquid system transforms liquid pesticides into fine droplets; second, the wind delivery system generates directional high-speed airflow, which powerfully pushes the droplets into the interior of the tree canopy, while simultaneously causing the branches and leaves to turn over, ensuring that the droplets cover both sides of the leaves and hidden areas, thus solving the problems of weak penetration and uneven coverage of traditional spraying.

[0003] Chinese patent CN220458391U discloses a self-propelled sprayer that utilizes a dispersing component and a fan to draw in air through a dispersing chamber, which facilitates the dispersion of the pesticide solution, resulting in more uniform pesticide distribution and improved absorption by fruit trees, effectively reducing pesticide waste. The adjustment plate can be adjusted to suit the spraying needs of different heights and fruit tree species. The diverter disperses the air drawn in by the fan, reducing air collisions and backflow, thus increasing the aerodynamic force entering the dispersing chamber and further dispersing the pesticide mist.

[0004] Although the above solution uses a frustum-shaped diffuser to divert air and reduce air collision and backflow, the air is still impacted by the inner wall of the casing because it is dispersed in a circular shape before being discharged into the drug dispersing component to blow the atomized drug. This causes internal air consumption and thus affects the atomization and spraying effect of the drug.

[0005] Therefore, this utility model provides an air intake guide mechanism for orchard wind-driven spray equipment to solve the above problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides an air intake guide mechanism for orchard air-assisted spraying equipment to solve the problem that the air is dispersed in a circumferential shape and is still impacted by the inner wall of the machine casing before being discharged into the powdering component to blow the atomized pesticide. This causes air loss and affects the atomization and spraying effect of the pesticide.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An air intake guiding mechanism for an orchard wind-driven spraying device includes a diffuser box and an air inlet box. The diffuser box has a diffuser cavity. One end of the air inlet box is detachably installed on the diffuser box. A frustum is fixedly connected inside the air inlet box. A circumferentially arrayed air deflector strips are fixedly connected to the frustum. The air inlet box has a circumferentially arrayed air inlet, and the air inlet and air inlet are connected to the diffuser cavity. The air inlet is located between two of the air deflector strips. An air supply component for supplying air into the air inlet box is provided on the diffuser box.

[0008] Furthermore, two spray pipes are installed inside the air dissipation chamber, and the two spray pipes are arranged symmetrically inside the air dissipation chamber.

[0009] Furthermore, a connecting ring is fixedly connected to the air inlet box, and a first bolt is installed on the connecting ring, and the connecting ring is installed on the air diffuser box by the first bolt.

[0010] Furthermore, a connecting pipe is fixedly connected to the frustum base, and a flow divider is fixedly connected to the connecting pipe.

[0011] Furthermore, an auxiliary sleeve is fixedly connected inside the air dissipation cavity, and the auxiliary sleeve and the connecting pipe are coaxially arranged. A sealing cover is fixedly connected inside the air dissipation cavity, and the auxiliary sleeve is located inside the sealing cover.

[0012] Furthermore, the air supply assembly includes a motor mounted on the air diffuser box, the output shaft of the motor is equipped with a rotating shaft, one end of the rotating shaft passes through an auxiliary sleeve, a frustum base and a connecting pipe in sequence and is fixedly connected to a fan blade.

[0013] Furthermore, a filter plate is provided at the end of the air inlet box away from the air distribution box. The filter plate has filter holes and a second bolt is installed on the filter plate. The filter plate is installed on the air inlet box by the second bolt.

[0014] The beneficial effects of this utility model are as follows: 1. This device uses a circular array of deflector strips on the truncated cone base inside the air inlet box to precisely limit and guide the incoming air, directing it directly to the air inlet and into the diffuser chamber. At the same time, the arc surface of the connecting pipe can pre-divide the airflow. Combined with the sealed cover inside the diffuser chamber, it can reduce the diffusion and collision of air towards the auxiliary sleeve. With the synergistic effect of multiple structures, the airflow avoids ineffective impacts and backflow during the delivery process, maximizing the preservation of airflow dynamics and providing stable power support for the efficient delivery of mist droplets.

[0015] 2. The air inlet box of this device can be detachably installed on the air distribution box via a connecting ring and the first bolt. The filter plate is fixed to the end of the air inlet box via the second bolt. The detachable structure makes it easy for staff to regularly disassemble and clean the internal components of the air inlet box and replace the filter plate. The filter holes on the filter plate can pre-filter the air entering the air inlet box, blocking impurities from entering the equipment and preventing key components such as fan blades and spray heads from being blocked or damaged by impurities, thus extending the overall service life of the equipment.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] An air intake guide mechanism for orchard pneumatic spraying equipment, as shown in the attached... Figure 1-4 As shown, it includes an air diffuser box 1 and an air inlet box 4. An air diffuser chamber 2 is provided on the air diffuser box 1. Two spray pipes 3 are installed in the air diffuser chamber 2 and are symmetrically arranged in the air diffuser chamber 2. The spray pipes 3 are connected to the medicine tank through a water pump. The medicine is pressurized by the water pump and transported to the spray pipes 3. The medicine is sprayed out in a mist form through the spray head on the spray pipes 3.

[0020] In this embodiment, one end of the air inlet box 4 is detachably installed on the air diffuser box 1. A connecting ring 15 is fixedly connected to the air inlet box 4, and a first bolt 16 is installed on the connecting ring 15. The connecting ring 15 is installed on the air diffuser box 1 by the first bolt 16.

[0021] The air diffuser box 1 has pre-drilled screw holes. After the connecting ring 15 on the air inlet box 4 is attached to the air diffuser box 1, the first bolt 16 is screwed into the screw hole to fix the air inlet box 4 on the air diffuser box 1.

[0022] In this embodiment, a frustum base 5 is fixedly connected inside the air inlet box 4. A circumferential array of air deflectors 6 is fixedly connected to the frustum base 5. An circumferential array of air inlets 7 is opened on the air inlet box 4. The air inlet box 4 and the air inlets 7 are connected to the air distribution chamber 2. The air inlets 7 are located between two air deflectors 6. A connecting pipe 8 is fixedly connected to the frustum base 5. A flow divider 9 is fixedly connected to the connecting pipe 8.

[0023] The truncated cone base 5 is truncated cone in shape. The deflector strips 6 can be arranged in an umbrella shape or in a spiral shape on the truncated cone base 5. After the air is blown onto the truncated cone base 5, it is directly transported to the air inlet 7 under the limiting and guiding effect of the deflector strips 6, and then transported to the interior of the air diffuser 2 through the air inlet 7. The connecting pipe 8 is located on one side of the truncated cone end of the truncated cone base 5, and its arc surface contacts the air first, thus diverting the air blown onto the truncated cone base 5.

[0024] In this embodiment, an auxiliary sleeve 13 is fixedly connected inside the air dissipation chamber 2, and the auxiliary sleeve 13 and the connecting pipe 8 are coaxially arranged. A sealing cover 14 is fixedly connected inside the air dissipation chamber 2, and the auxiliary sleeve 13 is located inside the sealing cover 14.

[0025] The air entering the air distribution chamber 2 through the air inlet 7 will be outside the sealed cover 14. The sealed cover 14 reduces the amount of air blown to the auxiliary sleeve 13, thereby reducing the internal air loss.

[0026] In this embodiment, the air distribution box 1 is provided with an air supply component that supplies air into the air inlet box 4. The air supply component includes a motor 12 installed on the air distribution box 1. The output shaft of the motor 12 is equipped with a rotating shaft 11. One end of the rotating shaft 11 passes through the auxiliary sleeve 13, the frustum base 5 and the connecting pipe 8 in sequence and is fixedly connected to the fan blade 10.

[0027] It should be noted that the power source of the motor 12 in this embodiment is not limited. It can be a battery or directly connected to a power cord.

A suitable controller can be selected according to the actual situation to meet the control requirements. The specific connection and control sequence, as well as the detailed connection methods, are technologies known to those skilled in the art.

[0028] The output shaft of motor 12 drives the rotating shaft 11 to rotate, which in turn drives the fan blade 10 to rotate inside the air inlet box 4. The resulting suction force can draw outside air into the air inlet box 4.

[0029] In this embodiment, a filter plate 17 is provided at the end of the air inlet box 4 away from the air distribution box 1. The filter plate 17 has filter holes 18 and a second bolt 19 is installed on the filter plate 17. The filter plate 17 is installed on the air inlet box 4 by the second bolt 19.

[0030] The air inlet box 4 is designed with screw holes. After the filter plate 17 is attached to the air inlet box 4, it can be fixed on the air inlet box 4 by screwing the second bolt 19 into the screw hole. The air entering the air inlet box 4 from the outside can be pre-filtered through the filter hole 18 before entering the air inlet box 4.
