DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] A fan structure of a pesticide spraying machine, like Figure 1 and Figure 2 and Figure 3 , comprising a fan, a mounting plate 11 arranged on one side of a frame 1 and used for mounting a rotating shaft 12 of the fan, the fan comprising the rotating shaft 12 and a fan 121 arranged on the rotating shaft 12, the rotating shaft 12 being rotationally connected with the mounting plate 11, the rotating shaft 12 rotating to drive the fan 121 to rotate, the upper end of the mounting plate 11 being arc-shaped, the lower end of the mounting plate 11 being connected with a vertical plate 13 parallel to the mounting plate 11 through a horizontal plate, the vertical plate 13 being provided with an air inlet pipe 131 on the plate surface, the air inlet pipe 131 being horizontally distributed and provided with a grid plate at the end away from the vertical plate 13, the fan 121 being arranged in the air inlet pipe 131, so that there is a gap between the fan 121 and the mounting plate 11, a plurality of flow guide plates 14 being arranged between the mounting plate 11 and the vertical plate 13, and a plurality of flow adjusting plates 15 being arranged on the plate surface of the mounting plate 11 and located on the left and right sides of the fan 121.

[0025] As Figure 2 and Figure 3 The inclination angle A of the flow guide plate 14 gradually increases from the position directly above the mounting plate 11 to the direction of the inclined plate 161 on both sides, and the inclination angle A of the flow guide plate 14 is the included angle between the plate surface of the flow guide plate 14 and the vertical plane, that is, the flow guide plate 14 is arranged to be vertically distributed at the uppermost position of the mounting plate 11, so as to facilitate the upward guiding of the air.

[0026] like Figure 2 and Figure 3 The fan 121 rotates through the shaft 12, causing air to enter between the mounting plate 11 and the vertical plate 13 through the air inlet pipe 131. The function of the flow regulating plate 15 is to guide the air upward before the air pressure is formed, and then blow it upward from the air duct between the mounting plate 11 and the vertical plate 13, increasing the upward blowing height of the fan. The remaining air is blown out from the left and right sides of the mounting plate 11 through the guide plates 14 on the left and right sides of the mounting plate 11, thereby achieving the spraying effect around the sprayer and at high places.

[0027] like Figure 1 and Figure 3 The horizontal plate includes a horizontal plate 16 at the bottom of the mounting plate 11 and inclined plates 161 on the left and right sides of the horizontal plate 16. The inclined plates 161 are gradually inclined upwards away from the horizontal plate 16. The guide plate 14 is distributed close to the inclined plate 161. At this time, the horizontal plate closes the bottom of the mounting plate 11 and the vertical plate 13, so that the air outlet direction of the fan is the left and right sides and the top of the mounting plate 11.

[0028] like Figure 1 and Figure 3 The deflector plate 15 is an inclined plate, and the angle between it and the vertical plane decreases as it approaches the upper end of the mounting plate 11. This is to facilitate the upward guidance of the airflow entering the air inlet duct 131. To adjust the angle of each deflector plate 15, the plate surface of each deflector plate 15 is perpendicular to the plate surface of the mounting plate 11, and each deflector plate 15 is provided with a connecting plate 17 that contacts the plate surface of the mounting plate 11. A locking screw is passed through the connecting plate 17, and one end of the locking screw passes through the connecting plate 17 and is threaded to the plate surface of the mounting plate 11. When the nut of the locking screw is engaged with the connecting plate 17, the screw is engaged with the plate surface of the mounting plate 11. When the connecting plate 17 is in contact with the side opposite to the mounting plate 11, the locking screw fixes the connecting plate 17 to the mounting plate 11. The connecting plate 17 is installed on the mounting plate 11 by the locking screw, and then the flow regulating plate 15 is installed on the mounting plate 11. When it is necessary to adjust the angle of the flow regulating plate 15, the locking screw is turned so that the nut of the locking screw is separated from the connecting plate 17, so that it is easy to rotate the angle of the flow regulating plate 15, adjust the amount of upward air guided by the flow regulating plate 15, and thus control the height of the air outlet from the top of the mounting plate 11 to meet the spraying needs of various fruit trees or crops.

[0029] like Figure 3 When the fan 121 shown rotates clockwise, each airflow deflector 15 has an arc-shaped edge at the end where the air enters the deflector 15, in order to facilitate better airflow guidance.

[0030] like Figure 1 and Figure 3, the installation plate 11 is provided with liquid delivery pipes 18 along the edge of the installation plate 11 on the side away from the vertical plate 13, the liquid delivery pipes 18 are provided with a plurality of nozzles 181 penetrating through the installation plate 11, the installation plate 11 is provided with through holes for the nozzles 181 to penetrate through, and one nozzle 181 is distributed between two adjacent guide plates 14. At this time, the liquid delivery pipes 18 input liquid medicine into the nozzles 181 for spraying, and the wind blown from between the adjacent guide plates 14 carries the liquid medicine to spray onto the crops.

[0031] As Figure 1 and Figure 3 The rotating rod 19 is fixedly penetrated in the middle of each guide plate 14, the two ends of the rotating rod 19 respectively penetrate out of the side of the installation plate 11 and the vertical plate 13 away from each other, and the penetrating end is threadedly connected with a locking block (not shown in the figure). When the locking block is in contact with the installation plate 11 or the vertical plate 13 by rotating the locking block, the position of the rotating rod 19 is fixed, so that the inclination angle of the guide plate 14 is fixed. When the locking block is away from the installation plate 11 or the vertical plate 13 by rotating the locking block, the rotating rod 19 is convenient to adjust the inclination angle of the guide plate 14.

[0032] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies thereof, the present application also intends to include these modifications and variations.
