[0029] To ensure the stability of the second spray boom 403 in a horizontal state and prevent the second spray boom 403 from rotating at the horizontal rotation pair 601 when operating in a horizontal state, in an embodiment of the utility model, a first clamping member 15 is provided at the horizontal rotation pair 601. Specifically, the horizontal rotation pair 601 is arranged inside the first clamping member 15, and one end of the first clamping member 15 is fixedly connected to the vertical rotation pair 501.

[0031] When the spray bar spray device of the embodiment of the utility model is working, when the spray bar spray device is ready to enter the greenhouse for operation, the horizontal folding mechanism 5 is controlled by the remote controller 12 to make the second spray bar 403 fold toward the frame body 1 in the horizontal plane (assuming that the second spray bar is in a horizontal extension state before entering the greenhouse), so as to reduce the width of the entire spray bar so as to smoothly pass through the greenhouse entrance and enter the greenhouse for spraying operation. When the entire spray bar spray device enters the greenhouse, the second spray bar 403 is controlled to return to a horizontal state according to the operation requirements (assuming that the spray bar and the nozzle thereon need to spray downward), and then the driving wheel 7 and the liquid supply pump 3 are controlled to work, so as to realize the walking spray of the spray device. When the spraying operation in the greenhouse is completed, the driving wheel 7 and the liquid supply pump 3 are controlled to stop working, and the second spray bar 403 is controlled to fold toward the frame body 1 in the horizontal plane again, and after the folding is completed, it drives out from the other end of the greenhouse.

[0032] It should be noted that when the second spray boom 403 is controlled to fold toward the frame body 1 in a horizontal plane, it is necessary to synchronously control the winding device 603 according to the position change of the second spray boom 403 during the folding process to adaptively release or wind up the pull rope, so as to prevent the pull rope 603 from affecting the folding of the second spray boom 403.

When the entire spray boom spray device enters the greenhouse, according to the need for side spraying of crops on both sides, the second spray boom 403 is first controlled to return to a horizontal state, and then the winding device 603 is controlled to pull the second spray boom 403 upwards through the pull rope 602 to achieve folding, so that the second spray boom 403 is in a vertical state and fixed on the second clamping member 16, and then the driving wheel 7 and the liquid supply pump 3 are controlled to operate, so as to achieve the side spraying of the crops on both sides by the spray boom spray device of the utility model. After the secondary lateral spraying operation is completed, the driving wheel 7 and the liquid supply pump 3 are controlled to stop working, the winding device 603 is controlled to release the pull rope 602, and the second spray rod 403 is manually taken out from the second clamping member 16 and released, until the second spray rod is in a horizontal state and is fixed to the first clamping member 15 again, and finally the second spray rod 403 is controlled to fold toward the frame body 1 in the horizontal plane, and after the folding is completed, it drives out from the other end exit of the greenhouse.

[0035] The spray bar spray device of the utility model has a simple structure and is easy to control. The horizontal folding mechanism 5 and the vertical folding mechanism 6 are provided to realize the folding of the second spray bar in the horizontal plane and the vertical plane, which is convenient for transportation and entering and exiting a greenhouse with a small space.
