[0002] Greenhouse plant protection is a very important link in agricultural production, affecting the healthy growth of crops. The methods of plant protection include chemical control, physical control and biological control, etc. Since chemical control has the characteristics of high efficiency and timely control, it can timely control and control suddenness. When protecting plants in greenhouses, sprayers are needed. For example, the dual-purpose high-efficiency plant protection sprayer with publication number CN102428905A can realize the rapid conversion of two spray modes, air curtain spray boom spray and axial flow air delivery spray, by controlling the air supply direction of the axial flow fan, the flow direction of the two-position three-way solenoid valve, and the opening and closing of the elbow, so as to meet the requirements of two different plant protection operations, field plant protection operation and tree pest control, and make full use of machine resources. However, the above-mentioned device still has certain shortcomings when used. When spraying in the greenhouse, due to the different agricultural products planted in the greenhouse, the required soil area is also different. At this time, spraying is carried out in the face of plants between different rows, so it is necessary to adjust the position of the nozzle, and the above-mentioned sprayer cannot effectively adjust the position of the nozzle to adapt to the soil between different rows.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that when the sprayer on the market performs spraying in the greenhouse, different agricultural products planted in the greenhouse require different soil areas, and the spraying is performed on plants in different rows, so the position of the nozzle needs to be adjusted, and the above-mentioned sprayer cannot effectively adjust the position of the nozzle to adapt to the soil in different rows. Figure 1 , Attachment Figure 2 and attached Figure 4 -Attached Figure 7, an adjustment mechanism is arranged on the outside of the rotating disk 13, and the adjustment mechanism includes two groups of second spray racks 18 arranged on one side of the bottom of the spray rack 1, and the outer side of the end of the second spray rack 18 is arranged on the outer side of the guide rod 20, and the right end position of the second spray rack 18 is connected to one end of the spray box 3 through the second water pipe 19. The adjustment mechanism includes a rotating rod 16 rotatably connected to the outer side of the bottom edge of the rotating disk 13, and the rotating rod 16 is rotatably connected to the top of the limiting push rod 17 at an end position away from the rotating disk 13, and the bottom position of the limiting push rod 17 is fixed at the top position of the second spray rack 18. The rotation range of the rotating disk 13 is 0-90°, and the limiting push rod 17 is integrated with the top position of the second spray rack 18. The limiting push rod 17 forms a sliding structure between the rotating rod 16 and the outer side of the guide rod 20. The connecting limiting rod 15 forms a sliding structure with the inside of the fixed plate 5 through the electric push rod 14, and the convex block of the connecting limiting rod 15 and the inside of the output end of the driving motor 6 form a clamping structure.

[0020] First, when in use, ensure that the liquid inside the spray box 3 is fully mixed. By starting the electric push rod 14, the output end of the electric push rod 14 will drive the connection limit rod 15 to slide inside the fixed plate 5. At this time, the protrusion on the top of the connection limit rod 15 will extend into the output end of the drive motor 6. At this time, by starting the drive motor 6, the output end of the drive motor 6 can drive the rotating disk 13 to rotate through the connection limit rod 15. At this time, the electric push rod 14 will not rotate. When the output end of the drive motor 6 drives the rotating disk 13 to rotate, the rotating disk 13 will also drive the rotating rod 16 to rotate, so that the rotating rod 16 will drive the limit push rod 17 to move, so that the limit push rod 17 will drive the second spray rack 18 to slide on the outside of the guide rod 20, and the guide rod 20 is fixed at the inner position of the spray rack 1. At this time, the movement of the second spray rack 18 can drive the second water pipe 19 to move, so that the position of the second spray rack 18 can be adjusted, so that it is convenient to spray plants between different rows.

[0021] Example 2: In order to facilitate the full spray treatment of plants, please refer to the attached Figure 1 -Attached Figure 3, comprising a spray rack 1, a group of handles 2 are fixed to the right side wall of the spray rack 1, a spray box 3 for injecting liquid is fixed inside the spray rack 1, and a group of driving rollers 4 are installed at the bottom of the spray rack 1. A group of fixed plates 5 are fixed at the top position of the left side of the spray rack 1, and a group of drive motors 6 are fixed at the top position of the fixed plate 5. The output end position of the drive motor 6 is fixed at the center position of the circle of the sector gear 7; one side position of the spray box 3 is respectively connected to the first water pipe 12 and one end of the first spray rack 11, and the front and rear ends of the first spray rack 11 are rotatably arranged at the top position of the fixed plate 5; a group of rotating disks 13 are rotatably arranged at the bottom position of the fixed plate 5, and a group of electric push rods 14 are arranged at the bottom center position of the rotating disk 13. One side of the bottom of the electric push rod 14 is fixed to the outside of the spray rack 1 through a rod, and the output end of the electric push rod 14 is rotatably connected to a connecting limit rod 15, and the top position of the connecting limit rod 15 is slidably arranged inside the fixed plate 5 and the top of the connecting limit rod 15 can extend into the output end of the drive motor 6. A group of valves are arranged at the middle end positions of the first water pipe 12 and the second water pipe 19, and the two ends of the guide rod 20 are fixed at the side wall positions of the spray rack 1. A group of rotating gears 8 are meshed and connected to the outer side of the sector gear 7. The bottom position of the rotating gear 8 is connected to the top position of the fixed plate 5 through a reset torsion spring 9. A group of pull ropes 10 are wound around the outer side of the top of the rotating gear 8. The other end of the pull rope 10 is wound around the outer side of the end of the first spray rack 11. The rotation range of the first spray rack 11 is 0-50°. The rotating gear 8 forms a reciprocating rotation structure with the top position of the fixed plate 5 through the reset torsion spring 9. The end position of the first spray rack 11 away from the pull rope 10 is connected to the top position of the fixed plate 5 through a group of torsion springs that facilitate the reset of the pull rope 10.

[0022] In order to adjust the angle, it is ensured that the top protrusion of the connecting limit rod 15 is not inside the output end of the driving motor 6. By starting the driving motor 6, the output end position of the driving motor 6 drives the fan gear 7 to rotate, so that the rotating gear 8 engaged and connected at the outer position of the fan gear 7 rotates. When the rotating gear 8 is engaged with the fan gear 7, the rotating gear 8 will drive the reset torsion spring 9 to deform. At this time, the pull rope 10 wrapped around the top of the rotating gear 8 drives the first spray rack 11 to rotate, so that the first spray rack 11 will also drive the torsion spring to deform. When the rotating gear 8 is no longer engaged with the fan gear 7, the rotating gear 8 will also be reset by the reset torsion spring 9. In addition, the first spray rack 11 is also rotated in multiple positions by the torsion spring, so as to facilitate the spraying process.
