[0021] Example 1

[0022] See Figure 1The present invention provides a multi-degree-of-freedom adjustable spraying mechanism, including a nozzle 3-1 and a multi-degree-of-freedom adjustable frame for hinged nozzle 3-1.

[0023] Among them, the nozzle 3-1 is provided with protruding pillars 301 on two symmetrical sides, and the nozzle 3-1 is also provided with a pipe joint 302. The central axis of the pipe joint 302 is perpendicular to the line connecting the two protruding pillars 301, and the pipe joint 302 and the protruding pillars 301 are located on the same plane.

[0024] The multi-degree-of-freedom adjustable frame includes a boom rod 3-21, a nozzle bracket 3-2 hinged to the top of the boom rod 3-21 by a first electric push rod 3-51, a slewing support 3-17 hinged to the bottom of the boom rod 3-21 by a second electric push rod 3-52, and a base 3-14 sleeved on the slewing support 3-17. The slewing support 3-17 can rotate relative to the base 3-14. Of course, in large-scale applications, the first electric push rod 3-51 and the second electric push rod 3-52 can be replaced by hydraulic cylinders, hydraulic motors, hydraulic pumps, etc.

[0025] The nozzle support includes a U-shaped arm, with two side lugs 321 vertically connected to the closed side of the U-shaped arm. The two side lugs 321 are located on both sides of the center point of the closed side of the U-shaped arm. A pair of upper shaft lugs 322 are vertically connected to the upper edge of the side lugs 321.

[0026] The upper part of the boom rod 3-21 is provided with an upper V-shaped connecting lug 3-211. One pair of lugs of the upper V-shaped connecting lug 3-211 are in the same direction as the boom rod 3-21, and the other pair of lugs of the upper V-shaped connecting lug 3-211 are located on the back side of the boom rod 3-21. The lower part of the boom rod 3-21 is provided with a forked connecting lug. One pair of connecting lugs 3-212 of the forked connecting lug are in the same direction as the boom rod 3-21, and the other pair of connecting lugs 3-213 are located on the belly of the boom rod 3-21.

[0027] The slewing support includes a shaft tube 3-17, a base plate 3-171 fixed to the top of the shaft tube 3-17, and a lower V-shaped connecting lug 3-172 provided on the base plate 3-171. The lower V-shaped connecting lug 3-172 includes another pair of side lugs arranged horizontally and a pair of oblique lugs connected above one end of the other pair of side lugs and arranged at an inclination.

[0028] The base includes a connecting plate 3-141 with a lug on one side and a straight tube 3-14 parallel to the connecting plate 3-141 and disposed in the hole of the lug.

[0029] The two arms of the U-shaped arm are rotatably connected to the protruding posts 301 on both sides of the nozzle 3-1. The pipe connector 302 of the nozzle 3-1 passes through the center of the closed side of the U-shaped arm and is used to connect the liquid delivery pipe. The two side lugs 321 of the nozzle support 3-2 are hinged to a pair of lugs of the V-shaped connecting lugs 3-211. The pair of upper shaft lugs 322 of the nozzle support 3-2 are hinged to the working end of the first electric push rod 3-51. The other end of the first electric push rod 3-51 is hinged to another pair of lugs of the V-shaped connecting lugs 3-211. The working end of the second electric push rod 3-52 is hinged to a pair of oblique lugs. The other end of the second electric push rod 3-52 is hinged to another pair of side lugs. The shaft tube 3-17 of the rotating support is inserted into the straight tube 3-14 of the base. The connecting plate 3-141 of the base is used to fix it to the liquid storage tank. The extension and retraction of the first electric push rod 3-51 can realize different spray swing angles of the nozzle 3-1. The extension and retraction of the second electric actuator 3-52 allows for different pitch angles of the boom 3-21, thus determining the spraying distance. The combined action of the two electric actuators can meet the spraying requirements at any position within the boom's reach. The slewing support's shaft tube 3-17 is inserted into the straight tube 3-14 of the base, enabling the slewing support to rotate 360 ​​degrees relative to the base in the horizontal plane. This, in turn, drives the entire boom 3-21 connected to the nozzle 3-1 on the slewing support to rotate 360 ​​degrees in the horizontal plane.

[0030] Furthermore, at the hinged joints at both ends of the boom rod 3-21, the second pin 3-4 is used in conjunction with the flat washer 3-8, spring washer 3-9, and nut 3-10 for assembly and locking to prevent axial escape; the remaining hinged joints on the boom rod 3-21 are assembled and connected using the first pin 3-3, spacer 3-6, and nut 3-7.

[0031] Furthermore, the multi-degree-of-freedom adjustable spraying mechanism can be electrically controlled to rotate 360 ​​degrees in the horizontal plane. Specifically, the multi-degree-of-freedom adjustable frame also includes a motor 3-11. The motor's output shaft vertically passes through the base plate 3-171 located next to the lower V-shaped connecting lug 3-172 and is connected to a motor gear 3-12. The straight tube 3-14 has an external gear ring (not shown in the figure) near its top; the external gear ring meshes with the motor gear 3-12. The rotation of the output shaft of the motor 3-11 drives the shaft tube 3-17 to rotate, thereby causing the spray head 3-1 to rotate 360 ​​degrees in the horizontal plane.

[0032] Furthermore, the nozzle is a multi-point nozzle 3-1, and in this example, a double-ring nozzle is used. Of course, a nozzle pipe can also be used.

[0033] See Figures 2-4 The multi-degree-of-freedom adjustable spraying mechanism of this utility model can be assembled on the medicine tank 2. After the pipe joint 302 of the nozzle 3-1 is connected to the pump 2-1 on the medicine tank 2 by the pipe fitting, spraying operation can be carried out conveniently.
