DETAILED DESCRIPTION

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] A greenhouse spray device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 7 As shown, a greenhouse spray device comprises a hook 1 and an I-beam 2 (the length of the I-beam 2 in the figure is the local length of the whole I-beam 2), the hook 1 is evenly fixedly installed on the top of the I-beam 2, the hook 1 can be adjusted up and down, and the top of the hook 1 is provided with a claw that can be deployed and clamped, which is used to clamp with the top support rod of the greenhouse, the bottom and left and right sides of the I-beam 2 are provided with a driving assembly 3, the driving assembly 3 comprises a mounting concave block 31, the bottom of the I-beam 2 is limitedly slidably connected with the mounting concave block 31, the inner side of the left and right sides of the top center of the mounting concave block 31 is limitedly rotatably connected with a driving wheel 32, and the driving wheels 32 on the left and right sides are connected with the bottom side of the I-beam 2 The upper ends of the edges are attached to each other, and the friction between the driving wheel 32 and the upper ends of the side edges at the bottom of the I-beam 2 is utilized to drive the mounting recessed block 31 to move during the rotation of the driving wheel 32. Motors 33 are fixedly installed on the outer sides of the left and right sides of the top center of the mounting recessed block 31, and the motor 33 is transmission-connected to the driving wheel 32 to drive the driving wheel 32 to rotate. An auxiliary wheel 34 is connected to the front and rear symmetrical limited rotation of the driving wheel 32 at the top of the mounting recessed block 31. The bottom cross-sections of the auxiliary wheel 34 and the driving wheel 32 are flush, so the auxiliary wheel 34 is also attached to the upper ends of the side edges at the bottom of the I-beam 2 to ensure that the mounting recessed block 31 moves stably at the bottom of the I-beam 2.

[0033] A driven wheel 35 is connected to the inner side of the middle part of the mounting recess 31 for limited rotation. The driven wheel 35 is attached to the bottom end of the I-beam 2. Therefore, during the movement of the mounting recess 31, the friction between the driven wheel 35 and the bottom end of the I-beam 2 can drive the driven wheel 35 to rotate. A rotating shaft 36 is fixedly installed at the left and right ends of the driven wheel 35. The middle area of ​​the rotating shaft 36 is in a "cross" shape. A mounting cross plate 37 is fixedly installed below the rotating shaft 36 at the left and right ends of the mounting recess 31. The end of the mounting cross plate 37 away from the mounting recess 31 is vertically bent upward, and is connected to the end of the rotating shaft 36 away from the mounting recess 31 for limited rotation, thereby improving the stability of the rotation of the rotating shaft 36.

[0034] When in use, the I-beam 2 is hung in the center of the top of the greenhouse by utilizing the expandable and clamping claws on the top of the hook 1 in cooperation with the support rods on the top of the greenhouse, and then the hanging height of the I-beam 2 is adjusted according to the height of the greenhouse by utilizing the design of the hook 1 that can be adjusted up and down.

[0035] When the installation is completed and the spraying work is carried out, the motor 33 is used to drive the driving wheel 32 to rotate. During the rotation process, with the help of the auxiliary wheel 34, the installation recess 31 can be driven to move back and forth stably at the bottom of the I-beam 2 to achieve comprehensive spraying in the greenhouse. During the movement of the installation recess 31, the friction between the driven wheel 35 and the bottom end of the I-beam 2 can drive the driven wheel 35 to rotate, thereby driving the rotating shaft 36 to rotate above the installation cross plate 37.

[0036] like Figure 1 , Figure 6-Figure 10 As shown, a spray assembly 4 is arranged on the outer side between the rotating shaft 36 and the mounting cross plate 37, and the spray assembly 4 includes a concave block 41, and the outer periphery of the rotating shaft 36 is movably connected with the concave block 41, and one side of the inner side of the concave block 41 is connected to a bevel gear 1 42 in a limited rotation manner, and the bevel gear 1 42 is limitedly slidably connected to the "cross"-shaped area of ​​the rotating shaft 36, so that the rotating shaft 36 can drive the bevel gear 1 42 to rotate, and the central limited rotation manner of the bottom of the inner side of the concave block 41 is connected to a bevel gear 2 43, and the bevel gear 2 43 is meshed with the bevel gear 1 42, so that when the bevel gear 1 42 rotates, it can drive the bevel gear 2 43 to rotate.

[0037] A rotating rod 44 is fixedly installed in the center of the bottom end of the bevel gear 2 43, and a rotating disk 45 is fixedly installed at the bottom end of the rotating rod 44. A limit block 46 is sleeved on the outer periphery of the middle part of the rotating rod 44. The limit block 46 is slidably connected to the inside of the mounting cross plate 37. The rotating rod 44 passes through the limit block 46 and is connected to the limit block 46 for relative rotation to improve the stability of the movement of the concave block 41.

[0038] The front and rear sides of the bottom end of the concave block 41 are symmetrically fixed with clamping plates 47, which are located on the front and rear sides of the mounting cross plate 37. The inner side of the bottom of the clamping plate 47 is slidably connected with a mounting slide plate 48 at upper and lower limit positions. The front and rear sides of the left and right mounting slide plates 48 are symmetrically penetrated by sliding rods 5. The mounting slide plate 48 is slidably connected to the left and right outside of the sliding rod 5. Connecting plates 6 are fixedly installed at the left and right ends of the sliding rod 5. The middle part of the connecting plate 6 is threadedly connected with a threaded column 7. The top end of the threaded column 7 is rotationally connected to the bottom end of the mounting cross plate 37 at a limit position, thereby realizing centralized up and down adjustment of the mounting slide plate 48.

[0039] The middle limit swing of the mounting slide 48 is connected with a rocker arm 49, and the limit swing position of the mounting slide 48 and the rocker arm 49 is aligned with the center of the turntable 45 up and down. A nozzle 410 is fixedly installed at the bottom end of the rocker arm 49 for spraying. A pulling rod 411 is arranged between the top of the rocker arm 49 and the bottom of the turntable 45. The bottom of the pulling rod 411 is telescopically sleeved with the rocker arm 49, and the top of the pulling rod 411 is limit rollingly connected at the eccentric position of the bottom of the turntable 45. Therefore, during the rotation of the turntable 45, the rocker arm 49 can be driven to swing by the pulling rod 411.

[0040] A water inlet pipe 8 is fixedly installed at the front and rear ends of the mounting recess 31. The water inlet pipe 8 is used to connect water for spraying. Connecting pipes 9 are fixedly connected between the left and right ends of the mounting recess 31 and the swing rod 49, as well as between adjacent swing rods 49. The connecting pipe 9 is used to transport the spray water input by the water inlet pipe 8 to the nozzle 410. The connecting pipe 9 is designed to be softly bent, which can not only complete the transportation of the spray water, but also meet the adjustment of the left and right movement of the nozzle 410.

[0041] When spraying, after the connection of the spray water is completed by using the water inlet pipe 8, the spray water enters the spray head 410 through the connecting pipe 9, and the spray head 410 is used to complete the spraying.

[0042] During the spraying process, the rotation of the rotating shaft 36 can drive the bevel gear 42 to rotate. During the rotation of the bevel gear 42, the mutual engagement of the bevel gear 42 and the bevel gear 2 43 can drive the bevel gear 2 43 to rotate. During the rotation of the bevel gear 2 43, the turntable 45 can be driven to rotate by the rotating rod 44. By utilizing the limited swing connection between the middle part of the rocker arm 49 and the middle part of the mounting slide 48, the design of the pulling rod 411 between the top of the rocker arm 49 and the bottom of the turntable 45, and the design of the limited rolling connection between the top of the pulling rod 411 and the eccentric part of the bottom of the turntable 45, during the rotation of the turntable 45, the nozzle 410 can be driven to swing through the pulling rod 411 and the rocker arm 49, thereby realizing swing spraying and increasing the spray range.

[0043] When it is necessary to adjust the spray position of the nozzle 410, the concave block 41 can be directly pushed to move left and right on the outside of the rotating shaft 36, and the clamping plate 47 can be used to drive the mounting slide plate 48 to move synchronously, thereby driving the nozzle 410 to adjust the position. The limiting sliding connection of the limit block 46 in the mounting cross plate 37 can ensure the stability during movement. The limiting rotation connection of the bevel gear 1 42 and the bevel gear 2 43 on the inner side of the concave block 41, combined with the limiting sliding connection between the bevel gear 1 42 and the "cross" shaped area of ​​the rotating shaft 36, will not affect the swing spray achieved by the rotation of the rotating shaft 36 during the movement and adjustment process.

[0044] When the swing amplitude needs to be adjusted, the threaded columns 7 on both sides can be rotated, and the threaded connection between the threaded columns 7 and the connecting plate 6 can be used to drive the middle slide bar 5 to move up and down. During the up and down movement of the slide bar 5, the mounting slide plate 48 and the slide bar 5 are connected, so that the mounting slide plate 48 can be driven to move up and down synchronously. In conjunction with the telescopic connection between the bottom of the pulling rod 411 and the rocker arm 49, during the up and down movement of the mounting slide plate 48, the swing length of the pulling rod 411 and the rocker arm 49 between the turntable 45 and the mounting slide plate 48 can be changed, thereby realizing the adjustment of the swing amplitude of the nozzle 410, which can be applied to different usage scenarios and is easy to operate.

[0045] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
