[0002] The purposes of paddy field harrowing mainly include leveling the planting surface, changing the soil structure, evenly applying basal fertilizer, and controlling weeds and plant roots. At present, the vast majority of paddy field harrowing adopts mechanized operation, and a tractor is used to mount a harrowing agricultural implement for harrowing operation. After the harrowing operation is completed, it is necessary to spray pesticides in time for the elimination of water bulrush. In the past, the spraying operation required people to carry a sprayer and walk in the muddy paddy field wearing boots, with a very high labor intensity and certain personal safety risks.

[0003] In view of this, this case proposes a spraying device for a paddy field harrowing vehicle, which sprays the pesticides for eliminating water bulrush during the harrowing process. Summary of the Utility Model

A bracket is fixedly provided at the front end of the vehicle body, and a rotating joint is fixedly provided on the bracket. One end of the rotating joint is connected to an electric sprayer fixed on the vehicle body through a pipeline, and the other end is connected to a spray rod;

[0007] One end of the spray rod far from the rotating joint is threadedly connected with a nozzle;

[0008] A swinging mechanism is provided on the bracket, and the swinging mechanism is movably connected to the spray rod. Driven by the swinging mechanism, the spray rod makes a reciprocating swing.

[0009] Further, the swinging mechanism includes a shaft, a disk, and a connecting rod. One end of the shaft is rotatably connected to the bracket, and the other end of the shaft is fixedly connected to the center of the disk; An eccentric rod is fixedly connected to the disk, the eccentric rod is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is hinged to the spray rod; The shaft is meshed and connected with a driving motor through gears.

[0010] Preferably, the spray rod is of a telescopic structure.

[0011] The utility model adopting the above technical solution can bring the following beneficial effects:

[0012] Compared with the traditional manual spraying method, the utility model has the advantages of reducing labor intensity and avoiding personal safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] As Figure 1 and Figure 2 shown, a spraying device for a paddy field harrowing vehicle includes a vehicle body 1 and a harrow 2 arranged at the rear end of the vehicle body 1; in order to realize the pesticide spraying operation while harrowing, a bracket 3 is fixedly arranged at the front end of the vehicle body 1. Specifically, the bracket 3 can be connected to a counterweight block in front of the vehicle body 1 by bolts so that the bracket 3 is detachable; a rotating joint 4 is fixedly arranged on the bracket 3. One end of the rotating joint 4 is connected to an electric sprayer 7 fixed on the vehicle body 1 through a pipeline, and the other end is connected to a spray rod 5. Specifically, the non-rotatable part of the rotating joint 4 is fixedly connected to the bracket 3, and this non-rotatable part is connected to the electric sprayer 7 through a pipeline; the rotatable part on the rotating joint 4 is connected to one end of the spray rod 5, and the other end of the spray rod 5, that is, the end of the spray rod 5 far from the rotating joint 4, is threadedly connected with a nozzle; the spray rod 5 is movably connected to a swing mechanism 6. Driven by the swing mechanism 6, the spray rod 5 swings reciprocally within a certain range with the rotating joint 4 as the center to perform pesticide spraying operation on a certain range of paddy fields; specifically, as Figure 3 shown, the swing mechanism 6 includes a shaft 61, a wheel disc 62 and a connecting rod 63. One end of the shaft 61 is rotatably connected to the bracket 3, and the other end of the shaft 61 is fixedly connected to the center of the wheel disc 62; an eccentric rod 64 is fixedly connected to the wheel disc 62. One end of the eccentric rod 64 is rotatably connected to one end of the connecting rod 63, and the other end of the connecting rod 63 is hinged to the spray rod 5; the shaft 61 is connected to a drive motor 65 through gear meshing;

[0018] It should be noted that the electric sprayer 7 can be freely placed at any position on the vehicle according to actual needs and should be fixed firmly;

[0019] In order to make the spraying range of the nozzle adjustable, the spray boom 5 is set as a telescopic structure; specifically, the spray boom 5 mainly includes an inner tube and an outer tube sleeved on the inner tube, and the inner tube and the outer tube are slidably connected; within the swinging range of the swinging mechanism 6, the longer the spray boom 5 is, the larger the spraying range is.

[0020] The working process of the present invention is briefly described as follows:

[0021] While harrowing, the electric sprayer 7 and the driving motor 65 are powered on, and the power is provided by the storage battery on the vehicle body 1; the swinging mechanism 6 drives the spray boom 5 to swing reciprocally, and the liquid medicine is sprayed through the nozzle within a certain range in the traveling direction of the vehicle body 1; the spraying work of the pesticide is completed while harrowing, and there is no need for manual spraying with a sprayer on the back, effectively reducing the labor intensity and also reducing the risk of personal safety.

[0022] The above is only the preferred specific embodiment of the present invention and is not a limitation to the present invention; any equivalent replacement and modification made by any person skilled in the art without departing from the guidance of the present invention shall be regarded as falling within the protection scope of the present invention.
