For example, Chinese patent publication No. CN207767350U discloses a foldable anti-collision spray boom for drones and a drone spraying device. However, after the spray boom is folded, the user needs to manually straighten it, which makes the spray boom more troublesome to use. At the same time, when the spring inside the spray boom for locking the spray pipe loses its elasticity due to aging, it needs to be replaced with a new spring to restore its elasticity. In addition, the spring is located inside the spray boom, which makes the spray boom maintenance process more troublesome. Utility Model Content

Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 6 As shown, an agricultural UAV anti-collision spray rod includes a first spray pipe 1, the left end of the first spray pipe 1 is fixedly connected to a hose 2, the left end of the hose 2 is fixedly connected to a second spray pipe 3, the hose 2 is larger than the distance between the right end of the first spray pipe 1 and the left end of the second spray pipe 3, the surface of the first spray pipe 1 is fixedly connected to a hollow column 4, the left side of the hollow column 4 and the upper surface of the second spray pipe 3 are fixedly connected to a rotating bracket 5, the surface of the rotating bracket 5 is fixedly connected to a gear 6, the upper surface of the hollow column 4 is provided with a reset bracket 7, the front face of the reset bracket 7 is fixedly connected to a rack 8, the rack 8 and the gear 6 are meshed with each other, the surface of the second spray pipe 3 is provided with a locking bracket 9, the surface of the locking bracket 9 is in contact with the inner wall of the rotating bracket 5, the left end of the second spray pipe 3 is fixedly connected to a sealing block 10, and the bottom of the second spray pipe 3 is fixedly connected to a spray head 11.

[0029] Among them, the rotating bracket 5 includes a connecting plate 501, a bearing 502, a circular cylinder 503, a first circular ring 504 and an arc groove 505.

[0030] The reset bracket 7 includes an electric push rod 701, a U-shaped plate 702, a guide square column 703 and a square tube 704. The bottom of the electric push rod 701 is fixedly connected to the upper surface of the hollow column 4, the left end of the electric push rod 701 is fixedly connected to the right side of the U-shaped plate 702, the left and right sides of the guide square column 703 are fixedly connected to the inner wall of the U-shaped plate 702, the inner wall of the square tube 704 is in contact with the surface of the guide square column 703, and the front of the square tube 704 is fixedly connected to the back of the rack 8.

[0031] It should be noted that, through the cooperation of the connecting plate 501, the bearing 502, the circular column 503 and the circular ring, the second spray pipe 3 can rotate around the circular column 503 after being hit, and the position of the rack 8 can be changed through the cooperation of the gear 6 and the rack 8. At the same time, through the cooperation of the U-shaped plate 702, the guide square column 703 and the square tube 704, the electric push rod 701 can push the rack 8 to the left or right, and when the reset bracket 7 pushes the rack 8 to the initial position, the rotated second spray pipe 3 can be automatically straightened through the cooperation of the rack 8 and the gear 6.

[0032] like Figures 1 to 9As shown, the locking bracket 9 includes a second ring 901, a semi-cylinder 902, a spring 903, a third ring 904, a support block 905, a nut 906, a U-shaped column 907, an adjusting bolt 908 and a retaining ring 909. The surface of the second ring 901 is in contact with the inner wall of the second spray pipe 3, the right side of the second ring 901 is fixedly connected to the left side of the semi-cylinder 902, the surface of the semi-cylinder 902 is in contact with the inner wall of the arc groove 505, the left side of the second ring 901 is fixedly connected to the right side of the spring 903, and the left side of the spring 903 is fixed to the right side of the third ring 904.

[0033] It should be noted that, through the thrust of the spring 903 on the second ring 901, the semi-cylinder 902 is in close contact with the arc groove 505, and the cooperation between the semi-cylinder 902 and the arc groove 505 makes it impossible for the second spraying pipe 3 to rotate when it is not hit. When the second spraying pipe 3 is hit, the semi-cylinder 902 will automatically slide out of the arc groove 505 through the arc surface in contact with the arc groove 505. At the same time, the retaining ring 909 can prevent the adjusting bolt 908 from sliding left and right, and when the adjusting bolt 908 is During rotation, the third ring 904 is moved to the left or right by adjusting the cooperation between the bolt 908 and the nut 906. At this time, the thrust of the spring 903 on the second ring 901 can be changed by adjusting the maximum distance between the first ring 504 and the second ring 901.

[0034] The working principle of the present utility model is as follows: first, the second spray pipe 3 is fixed to the agricultural drone, and the right end of the second spray pipe 3 is connected to the pump body on the agricultural drone. When the second spray pipe 3 is hit, the impact force causes the second spray pipe 3 to rotate around the circular column 503, and the gear 6 and the rack 8 cooperate to move the rack 8 to the left or right a certain distance.

[0035] After the second medicine spraying pipe 3 separates from the impacting object, the electric push rod 701 controls the movement of the U-shaped plate 702, and the rack 8 is pushed to the initial position through the cooperation of the U-shaped plate 702, the guide square column 703 and the square tube 704. At this time, the second medicine spraying pipe 3 can be automatically straightened through the cooperation of the rack 8 and the gear 6. At the same time, the thrust of the spring 903 on the second ring 901 makes the semi-cylinder 902 and the arc-shaped groove 505 closely contact each other, and the cooperation between the semi-cylinder 902 and the arc-shaped groove 505 prevents the second medicine spraying pipe 3 from rotating when not impacted.

[0036] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
