Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically a spraying device for agricultural planting greenhouses. Background Technology

[0002] Agricultural greenhouses, by controlling environmental conditions such as temperature, light, and moisture, can significantly increase crop yield, improve crop quality, save labor, and increase production efficiency. They also enable off-season cultivation, thereby achieving higher economic benefits. In addition, the quality of crops grown in greenhouses is improved, with significant improvements in color, shape, and nutrients. It is even possible to produce organic vegetables and high-quality rare varieties. To ensure that crops are not affected by pests and diseases, it is necessary to spray pesticides on crops inside the greenhouse.

[0003] A Chinese patent discloses a spraying device for agricultural greenhouses (authorization announcement number CN214709861U). This patented technology uses a wind duct, a second fixed frame, a first motor, a rotating shaft, and blades. The first motor drives the rotating shaft and blades to rotate. The nozzle can initially atomize the medicine in the storage tank, and the blades can completely atomize the water. The wind generated by the blades can spray the atomized medicine further and over a larger area, improving its practicality. However, it cannot spray crops in the greenhouse from all directions and affects the lower working space inside the greenhouse. Utility Model Content

[0020] Please see Figures 1-5 In this embodiment of the present invention, a spraying device for agricultural greenhouses includes a spraying component 1, a moving mechanism 2 is installed at one end of the spraying component 1, and a guiding mechanism 4 is installed at the other end of the spraying component 1. A set of cornering mechanisms 3 is installed between the spraying component 1 and the guiding mechanism 4.

[0021] exist Figure 2 In this system, the spraying assembly 1 includes a set of spray pipes 11 and a set of support pipes 12 connected to both ends of the spray pipes 11. A hose 16 is connected to one end of one of the support pipes 12, and a pesticide pump 15 is connected to one end of the hose 16. The output end of the pesticide pump 15 is connected to external liquid pesticide. Several nozzles 14 are installed at the lower end of each spray pipe 11, and a set of swivel joints 13 are installed at the connection between each spray pipe 11 and the support pipe 12. The pesticide is pumped into the hose 16 by the pesticide pump 15, and then sequentially enters the support pipe 12 and the spray pipe 11, and is then sprayed out from the nozzles 14 to spray the crops in the greenhouse.

[0022] exist Figure 2 and Figure 3In the process, the moving mechanism 2 includes a motor 21 and a bearing housing 28. The output end of the motor 21 is fixedly connected to a driving synchronous pulley 22 and a gearbox 23. A rotating shaft 29 is installed on the inner side of the bearing housing 28. A driven synchronous pulley 27 is fixedly connected to the rotating shaft 29. A synchronous belt 210 is installed on the outer sides of the driven synchronous pulley 27 and the driving synchronous pulley 22. A first connecting plate 211 is fixedly connected to the synchronous belt 210. A first suspension plate 26 is fixedly connected to one end of the first connecting plate 211. A set of first buckles 25 is fixedly connected to the lower end of the first suspension plate 26. The motor 21 and the bearing housing 28 are both fixedly installed on the upper part of the greenhouse. The motor 21 drives the driving synchronous pulley 22 to rotate. The driving synchronous pulley 22 drives the synchronous belt 210 and the driven synchronous pulley 27 to rotate together, so that the first connecting plate 211, the first suspension plate 26 and the first buckles 25 move in a straight line together. The first buckle 25 drives the support pipe 12 and the spray pipe 11 to move horizontally together. The output end of the gearbox 23 is fixedly connected to the winch 24. A set of first buckles 25 are fixed on a support pipe 12 connected to the hose 16. The hose 16 is wound around the winch 24. The motor 21 drives the drive synchronous pulley 22 to rotate and also drives the gearbox 23 to run. The gearbox 23 drives the winch 24 to rotate. During the rotation, the winch 24 winds up one end of the hose 16 and simultaneously winds up the other end of the hose 16. Through the speed transmission of the gearbox 23, the speed of the winch 24 is matched with the speed of the synchronous belt 210. This makes the horizontal movement speed of the spray pipe 11 match the winding and unwinding speed of the hose 16, which can ensure that the hose 16 is not pulled during the horizontal movement of the spray pipe 11 and can keep the hose 16 clean.

[0023] exist Figure 2 and Figure 4 In the middle, the guiding mechanism 4 includes a guide rod 45, with guide rod feet 46 fixedly connected to both the front and rear ends of the guide rod 45, and a guide sleeve 44 slidably connected to the outside of the guide rod 45. A second connecting plate 43 is fixedly connected to the outside of the guide sleeve 44, and a second suspension plate 41 is fixedly connected to one end of the second connecting plate 43. A set of second buckles 42 is fixedly connected to the lower end of the second suspension plate 41. The guide rod feet 46 are fixed to the upper part of the greenhouse, and the second buckles 42 are fixed to another support pipe 12 away from the hose 16. When the moving mechanism 2 drives the spraying assembly 1 to move horizontally, the second buckles 42, the second suspension plate 41, the second connecting plate 43 and the guide sleeve 44 move back and forth along the guide rod 45 together, so that the spraying assembly 1 keeps moving smoothly.

[0024] exist Figure 2 and Figure 5In the process, the corner mechanism 3 includes a cylinder 31, with a first rotating frame 32 rotatably connected to the upper end of the cylinder 31 and a second rotating frame 33 rotatably connected to the lower end of the cylinder 31. A third buckle 34 is fixedly connected to one end of the second rotating frame 33 and is fixed to the spray pipe 11. The first rotating frame 32 is fixed to the second suspension plate 41. When the cylinder 31 extends or retracts, it will pull the second rotating frame 33 and the third buckle 34. The third buckle 34 pulls the corresponding spray pipe 11, thereby causing the spray pipe 11 to rotate at a certain angle around the rotary joint 13, so as to achieve pesticide spraying at different angles.

[0025] The working principle of this utility model is as follows: First, the guide rod support 46 in the guide mechanism 4 and the motor 21 and bearing seat 28 in the moving mechanism 2 are fixedly installed on the upper part of the greenhouse. Then, the output end of the pesticide pump 15 is connected to the external liquid pesticide.

[0026] When it is necessary to spray pesticides on crops in the greenhouse, firstly, turn on the pesticide pump 15. The pesticide pump 15 pumps the external pesticide into the hose 16, then into the support pipe 12 and the spray pipe 11 in sequence, and then sprays it out from the nozzle 14 to spray the crops in the greenhouse.

[0027] Next, the motor 21 is turned on, which drives the active synchronous pulley 22 to rotate. The active synchronous pulley 22 drives the synchronous belt 210 and the driven synchronous pulley 27 to rotate together, thereby causing the first connecting plate 211, the first suspension plate 26 and the first buckle 25 to move in a straight line together; in turn, the support pipe 12 and the spray pipe 11 move horizontally along the guide rod 45, so that the crops in the whole greenhouse can be sprayed.

[0028] When the spraying angle needs to be adjusted, cylinder 31 is activated. The extension and retraction of cylinder 31 pulls the second rotating frame 33 and the third latch 34. The third latch 34 pulls the corresponding spraying pipe 11, thereby causing the spraying pipe 11 to rotate at a certain angle around the rotary joint 13, so as to achieve pesticide spraying at different angles.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
