[0024] The pesticide spraying mechanism 4 includes a first spray bar 41 and a second spray bar 42 located at both ends of the first spray bar 41. The storage tank 2 is connected to the first spray bar 41 and the second spray bar 42 respectively via a water pump 3. Specifically, the first spray bar 41 and the second spray bar 42 are made of hollow tubing. The inlet end of the water pump 3 is connected to the storage tank 2 via a water inlet pipe 31, and the outlet end of the water pump 3 is connected to a water supply pipe 32. The water supply pipe 32 is connected to the first spray bar 41 via a first flexible hose 33, and the first spray bar 41 and the second spray bar 42 are connected via a second flexible hose 34. A control valve 35 is provided on the water supply pipe 32.

[0025] The first spray bar 41 and the second spray bar 42 are respectively fixed on the first boom 43 and the second boom 44. The first boom 43 and the second boom 44 are hinged together by a hinge 45. The top of the second boom 44 is also connected to the first boom 43 through an adjustment structure 46, so that the second boom 44 can rotate 90° vertically around the hinge point of the hinge 45 and be in a vertically retracted state. The first boom 43 is connected to a fixing plate 47. The fixing plate 47 is hinged to the support 48 through a rotating arm, so that the fixing plate 47 can be flipped, so that the first boom 43 and the second boom 44 as a whole can rotate 90° vertically around the hinge point of the support 48 and be in a folded state, so that the first boom 43 and the second boom 44 can switch between the use position and the retracted folded position. When in the use position, the fixing plate 47 is supported on the first support part. When in the retracted folded position, the fixing plate 47 is supported on the second support part.

[0026] The first spray bar 41 and the second spray bar 42 are each equipped with multiple spray heads 49 arranged at intervals along their length. The pesticide in the storage tank is sprayed out from the multiple spray heads on the first spray bar 41 and the second spray bar 42 to achieve pesticide spraying.

[0027] The adjusting structure 46 is an inner telescopic rod structure, including an outer sleeve 461, an inner telescopic rod movably sleeved with the outer sleeve 461, and a locking member 463. A first hinge seat 464 is fixed to the top of the first boom 43, and a second hinge seat 465 is fixed to the top of the second boom 44. The end of the outer sleeve 461 is hinged to the first hinge seat 464, and the end of the inner telescopic rod is hinged to the second hinge seat 465. A locking member 463 is provided at the end of the inner telescopic rod near the outer sleeve 461. The locking member 463 can be a bolt fastener or an elastic locking member 463. When the fastener is bolted, during adjustment, loosen the bolt and then rotate the second boom 44 around the hinge point 45. The inner telescopic rod extends or retracts with the rotation of the second boom 44. When the inner telescopic rod extends, the second boom 44 is in an extended position; when the inner telescopic rod retracts, the second boom 44 rotates 90° vertically to a vertically retracted position. Finally, tighten the bolt to maintain the position of the second boom 44. Alternatively, the adjustment structure 46 can also use a telescopic cylinder mechanism, such as a hydraulic cylinder, to achieve automatic adjustment.

[0028] The first support includes a horizontal support rod 5 located on the front side of the support 48 and extending forward. The top of the horizontal support rod 5 has a first groove 51. When the first spray bar 41 and the second spray bar 42 are in the use position, the fixing plate 47 is engaged in the first groove 51. A first fastening bolt 52 is provided on the outer side of the first groove 51. When in the use position, the fixing plate 47 is in a downward-flipped state, engaging in the first groove 51 to form effective support, and is fixed by the first fastening bolt 52 to prevent shaking caused by vibration during use, ensuring the stability of the support in this state.

[0029] The second support includes an L-shaped support rod 6 located on the rear side of the support 48. The upper front end of the L-shaped support rod 6 has a second groove 61, and the top of the second groove 61 has a second fastening bolt 62. When the first spray bar 41 and the second spray bar 42 are in the folded position, the fixing plate 47 is engaged in the second groove 61. When in the folded position, the fixing plate 47 is flipped upwards and engaged in the second groove 61, and is fastened with the second bolt to ensure the stability of the support in this state.

[0030] The top of the walking frame 1 is provided with vertical support rods 7 on both sides. The top of the vertical support rods 7 is provided with a third groove 71. When the first spray bar 41 and the second spray bar 42 are in the folded position, the second arm 44, which is fixed to the second spray bar 42, can be locked in the third groove. When in the folded position, the end of the second arm 44, which is fixed to the second spray bar 42, near the storage box 2 can be locked into the third groove 71 to form effective support and improve the stability of the support.

[0031] When the work is deployed, the rotating arm rotates 90° counterclockwise forward around the hinge support 48, causing the fixing plate 47 to flip downward and lock into the first groove 51, and is tightened by the first bolt to form a stable support. Then, the bolt fixing parts on the inner telescopic rod are loosened, causing the first arm 43 to rotate 90° counterclockwise downward around the hinge point of the hinge 45, causing the first spray bar 41 to unfold. At this time, the inner telescopic rod extends and the bolt fixing parts are tightened to lock it, and the first spray bar 41 and the second spray bar 42 are in the unfolded working state.

[0032] When not in use and folded up, the first boom 43 rotates 90 degrees clockwise around the hinge point 45, causing the first spray bar 41 to bend upwards by 90 degrees. At this time, the inner telescopic rod retracts into the outer sleeve 461 and the bolt fixing parts are tightened to lock the fixed position. Then, the rotating arm rotates 90 degrees clockwise around the hinge support 48, causing the fixing plate 47 to flip upwards and be inserted into the second groove 61. The fixed position is then tightened by the second bolt. At this time, the second spray bar 42 rotates 90 degrees clockwise downwards, so that the end of the second boom 44 with the second spray bar 42 fixed near the storage box 2 can be inserted into the third groove 71 to form a support, so that the first spray bar 41 and the second spray bar 42 are in the folded up state.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
