Spraying equipment is needed in the growth operation of greenhouse crops, which is mainly used for spraying water and pesticides to ensure the growth and health of crops. Common spraying devices suitable for greenhouses usually adopt two kinds of walking type spraying, namely, air spraying and ground spraying.

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The specific embodiment is a pesticide spraying device for greenhouse planting, and a structural schematic diagram thereof is shown in Figs. 1 to 4 The specific embodiment is a pesticide spraying device for greenhouse planting, and a structural schematic diagram thereof is shown in

[0027] The spray bar 4 has a telescopic hose 32 connected to its upper middle section, and a water pipe 33 connected to the top of the telescopic hose 32. A drive assembly 34 is installed on one side of the inner side of the assembly frame 1. The drive assembly 34 includes a fixing frame 341, which is fixed to one side of the inner side of the assembly frame 1. A fixing sleeve 342 is fixed to the top of the fixing frame 341, and a drive motor 343 is installed in the middle of the fixing sleeve 342. Transmission rods 344 are connected to both ends of the drive motor 343. Half-gear rings 35 are fixed to the ends of the transmission rods 344 connected to both ends of the drive motor 343. A semi-gear ring 35 is fixedly provided around the end of each transmission rod 344. A linkage assembly 36 is provided on the same side of the two semi-gear rings 35. The linkage assembly 36 includes a double-sided gear guide 361, which is installed inside the assembly frame 1. A return spring 363 is connected to the top of the double-sided gear guide 361. A guide frame 362 is provided on the inner side of the assembly frame 1. The double-sided gear guide 361 and the guide frame 362 are connected by a movable guide connection. Gear ring sleeves 364 are fixedly provided around the two middle sections of the spray bar 4. The teeth on both sides of the double-sided gear guide 361 respectively engage with the semi-gear rings. 35 and gear ring sleeve 364 form a meshing transmission connection. The operator connects water pipe 33 to a water pump that pressurizes the pesticide source. The pesticide solution is guided by the telescopic hose 32 to the spray bar 4 and then sprayed out from the nozzles 5 below. During this process, the operator can start the drive motor 343 to make the transmission rods 344 connected at both ends rotate with their respective fixed half gear rings 35. At this time, the two sets of half gear rings 35 can lower the double-sided toothed guide frame 361 that meshes with them. At this time, the toothed edge of the other side of the double-sided toothed guide frame 361 can lower the gear ring sleeve 364 and its middle part. The fixed spray bar 4 is angled. When the smooth edge of the half gear ring 35 forms a gap with the double-sided toothed guide frame 361, the double-sided toothed guide frame 361 will rise due to the lack of meshing limit, according to the elasticity of the return spring 363 and the guidance of the guide frame 362. This can indirectly drive the spray bar 4 to reset its angle. By repeating this process, the spray bar 4 and the nozzles 5 at its bottom end can be cyclically oscillated to change the spray angle, thereby expanding the spraying range and ensuring that the pesticide can be evenly sprayed on both sides of the crop, reducing the problem of uneven spraying in the edge area caused by straight-line movement.

[0028] Working principle: the workers can pre-installed according to the installation mechanism 2 in the group set screw groove 23, bolt rod 24 will be installed on the frame 1 stable in the greenhouse high-speed travel mechanism or ground travel mechanism, thus to provide stable support force for the spray bar 4, second workers will be connected to the water pipe 33 pesticide water source pressurized water pump, wherein the pesticide water will be guided by the extension hose 32 to the spray bar 4, and then the lower part of the spray head 5 is sprayed, in the process, personnel can start the drive motor 343 to make both ends of the transmission rod 344 with the respective fixed gear ring 35 rotation, at this moment, two groups of gear ring 35 can be with the double side tooth guide 361 engaged with the gear ring 364 and the middle part of the fixed spray bar 4 to adjust the angle, when the half gear ring 35 light edge and double side tooth guide 361 form empty block, the double side tooth guide 361 will not be engaged with the limit and respectively according to the elasticity of the reset spring 363 and the guide of the guide frame 362 to rise, thus can indirectly with the spray bar 4 to adjust the angle reset, so as to achieve the reciprocating, that is, the spray bar 4 and the bottom of the spray head 5 can be reciprocating swing, so as to expand the spraying range, so that the pesticide can be evenly sprayed to the both sides of the crops, reduce the problem of uneven spraying caused by straight line walking.

[0029] All the technical features in the embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application, for the person skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
