Description

Technical Field

[0001] The invention relates to the technical field of agricultural greenhouse spraying, in particular to a timing spraying device for an agricultural greenhouse. Background Art

[0002] Early agricultural greenhouse spraying mostly used fixed spraying devices, which were mainly controlled manually or by simple machinery. The core structure was usually a fixedly installed spray head or pipe. Water / medicine liquid was directly transported from the water storage device through the pipe to the spray head for spraying.

[0003] With the development of facility agriculture, although some devices have introduced simple timing control, the following key problems still exist. First, the spray heads of existing devices are mostly fixed in direction, and it is difficult to adjust the swing angle according to demand, resulting in limited coverage and prone to spraying blind spots or repeated spraying. In addition, existing spraying devices require manual operation of the switch, which makes it difficult to achieve automatic timed spraying, which not only increases labor costs but also easily affects the water demand of crops due to operational delays. In addition, the existing spraying devices are not equipped with heating devices, so directly spraying cold water in low temperature environments may cause crop roots to freeze or growth to be hindered.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] See also Figures 1 to 8 The present invention provides a technical solution: a timed spraying device for an agricultural greenhouse, comprising a greenhouse main body 1, a water storage tank 2 fixedly installed near the inner roof of the greenhouse main body 1, a water outlet end of the water storage tank 2 fixedly connected to a water outlet pipe 4, an upper surface of the water storage tank 2 fixedly connected to a water inlet pipe 3, and the water inlet pipe 3 passes through the outer top surface of the greenhouse main body 1, a solenoid valve 5 fixedly installed on the water outlet pipe 4, a heating pipe 6 fixedly connected to the lower end of the water outlet pipe 4, a thermostat 7 fixedly installed on one side of the heating pipe 6, and a telescopic hose 8 fixedly connected to the lower end of the heating pipe 6;

[0039] The lower end of the telescopic hose 8 is fixedly connected to a spraying mechanism for timed spraying, and the spraying mechanism includes:

[0040] A hard tube 9 is fixedly connected to the lower end of the telescopic hose 8. The lower end of the hard tube 9 is fixedly connected to a transfer shell 10. The lower surface of the transfer shell 10 is evenly connected to a plurality of spray heads 11.

[0041] A steering swing mechanism is internally connected to an adjusting mechanism, one end of which is connected to a spraying mechanism so that the spraying mechanism swings left and right to realize swing-type spraying of the spraying mechanism, and after the adjusting mechanism adjusts the steering swing mechanism, the spraying swing angle is changed;

[0042] The lifting mechanism is fixedly installed inside the greenhouse body 1, and the other end of the lifting mechanism away from the spraying mechanism is connected to the steering swing mechanism, so that the spraying mechanism can be displaced in the vertical direction to achieve the rising and falling movement of the spraying height of the spraying mechanism.

[0043] More specifically, in this embodiment, a timing device electrically connected to the outside of the greenhouse body 1 triggers the opening of the solenoid valve 5, which causes the water in the water storage tank 2 to flow to the water outlet pipe 4, thereby achieving a timed spraying operation of the spraying device;

[0044] The water flowing through the outlet pipe 4 to the heating pipe 6 is also heated at a constant temperature under the control of the thermostat 7 on the heating pipe 6, thereby achieving flexible adjustment of the temperature suitable for spraying crops while achieving continuous constant temperature control. The thermostat 7 also has a built-in temperature sensor and is installed at the water outlet end of the heating pipe 6. It can detect the water temperature in real time and feed it back to the thermostat 7. The user can set the target temperature through the panel of the thermostat 7. When the water temperature is lower than the set value, the heating pipe 6 starts and automatically stops when it reaches the set value, thereby achieving constant temperature control.

[0045] At the same time, according to the spraying needs of crops in the greenhouse, the steering swing mechanism and the lifting mechanism are activated. The steering swing mechanism drives the spraying mechanism to realize the swing spraying operation, while the lifting mechanism drives the spraying mechanism to realize the change of height spraying, thereby achieving dual control adjustment of spraying height and direction. In this process, the range and comprehensiveness of spraying will be greatly improved.

[0046] As the water in the heating pipe 6 flows to the telescopic hose 8, the hard pipe 9 and the transfer shell 10, and the steering swing mechanism and the lifting mechanism coordinate in spraying adjustment, the spray head 11 completes a single timed spraying operation.

[0047] Among them, the telescopic hose 8 is made of flexible material and can freely expand and contract with the lifting and swinging of the spraying mechanism, avoiding the distortion or breakage of the pipe caused by the connection of the hard pipe 9, and ensuring the stability of water flow transmission.

[0048] Furthermore, the steering swing mechanism includes:

[0049] The rotating ring body 25 is fixedly connected to the interior of the rotating ring body 25. A through groove 27 is formed on one side of the surface of the curved plate 26. The curved plate 26 is fixedly connected to an adjustment connecting plate 29 at the through groove 27 via an adjustment mechanism. A ball socket 36 is formed on the surface of the adjustment connecting plate 29. A ball 37 is embedded in the ball socket 36. A connecting rod 31 is fixedly connected to the surface of the ball 37 near the spraying mechanism. A rotating frame 32 is fixedly connected to one side of the connecting rod 31.

[0050] A rotating platform 33 is installed on the side of the rotating ring body 25 close to the spraying mechanism. A limited rotation column 34 is installed inside the rotating platform 33 for limited rotation. The two ends of the rotating frame 32 are rotatably sleeved on both sides of the limited rotation column 34. A driving rod 35 is fixedly connected to the surface of the limited rotation column 34 on the other side away from the rotating frame 32. The driving rod 35 is fixedly connected to the hard pipe 9.

[0051] The regulatory agencies include:

[0052] The adjusting holes 28 are grouped into two, and the adjusting holes 28 in any group are evenly arranged on the arc plate 26 . An adjusting bolt 30 is threadedly connected between the adjusting connecting plate 29 and the adjusting holes 28 .

[0053] It is worth noting that the operation process of the steering swing mechanism is as follows: when the height adjustment of crop spraying is required, the second motor 22 is started, and the connecting flange 24 at its output end drives the rotating ring 25 to rotate. When the rotating ring 25 rotates, the radian plate 26 fixed inside it rotates synchronously. The radian plate 26 is connected to the adjustment connecting plate 29 through the through groove 27. Therefore, the rotation of the radian plate 26 will pull the adjustment connecting plate 29 to rotate along the rotation of the through groove 27. The rotation of the adjustment connecting plate 29 drives the ball in the ball socket 36 to rotate. The spherical contact ball 37 rotates by sliding in a low-friction manner. The rotation of the sphere 37 is thereby transmitted to the rotating frame 32 via the connecting rod 31. Since both ends of the rotating frame 32 are sleeved on the limit rotating posts 34 within the rotating platform 33, the rotating frame 32, when pushed by the connecting rod 31, will swing back and forth around the ends of the limit rotating posts 34. The swinging structure driven by the second motor 22 can upgrade the sprinkler head 11 from "fixed-direction spraying" to "left-right swinging spraying", thereby expanding the coverage area by 3-5 times.

[0054] The side of the limiting rotating column 34 away from the rotating frame 32 is fixedly connected to the driving rod 35, and the driving rod 35 is directly fixed to the hard pipe 9 of the spraying mechanism. Therefore, the swing of the rotating frame 32 will drive the hard pipe 9 and the transfer shell 10 at the lower end to swing left and right synchronously with the spraying head 11 through the driving rod 35, thereby achieving dynamic coverage of the spraying range.

[0055] Before this, if you need to adjust the swing amplitude, including expanding or reducing the angle, you can use the adjustment mechanism to achieve this purpose, as follows:

[0056] Loosen the threaded adjustment bolt 30 connecting the adjustment hole 28 and the arc plate 26, slide the adjustment connecting plate 29 along the through groove 27 to the adjustment hole 28 at different positions, and then re-tighten the adjustment bolt 30 to fix the adjustment hole 28 and the arc plate 26. The position change of the adjustment connecting plate 29 will change the push-pull stroke of the connecting rotating rod 31, thereby adjusting the swing amplitude of the rotating frame 32. In addition, it should be noted that the adjustment mechanism supports manual and flexible adjustment of the swing amplitude to adapt to the needs of different planting densities or crop types, specifically including small swings in densely planted areas and large coverage in sparse areas.

[0057] In addition, the limiting design of the rotating platform 33 and the limiting rotating column 34 avoids the dislocation of components during the swinging process, ensures the stability of the swinging trajectory of the spray head 11, and improves the spraying uniformity.

[0058] In addition, the lifting mechanism includes:

[0059] A vertical support 12 is provided with a groove 13 on the side of the support 12 away from the steering and swinging mechanism. A first motor 14 is fixedly mounted on the inner bottom wall of the groove 13. The output end of the first motor 14 is fixedly connected to a rotating vertical column 15. A threaded surface 16 is provided on the middle end surface of the rotating vertical column 15. A threaded sleeve 18 is threadedly mounted on the threaded surface 16. A lifting frame plate 17 is integrally connected to one side of the threaded sleeve 18. The inner wall of the lifting frame plate 17 is sleeved on the outer surface of the vertical support 12.

[0060] The lifting frame plate 17 is fixedly connected to the lifting frame 23, and the rotating platform 33 is fixedly installed on one upper surface of the lifting frame 23;

[0061] A device groove 21 is provided on one side of the lifting frame plate 17 close to the steering and swinging mechanism. A second motor 22 is fixedly installed inside the device groove 21 . A connecting flange 24 is fixedly connected to the output end of the second motor 22 . The connecting flange 24 is connected to the rotating ring body 25 .

[0062] Furthermore, according to the crop height requirements, including the need for low-height spraying in the seedling stage and the need for higher coverage in the mature stage, the first motor 14 is started, and the rotating vertical column 15 at its output end begins to rotate. The middle end surface of the rotating vertical column 15 is provided with a threaded surface 16, and the threaded sleeve 18 is sleeved with the threaded surface 16 through an internal thread. When the rotating vertical column 15 rotates, the threaded sleeve 18 is acted upon by the thread force and moves up and down in the vertical direction along the threaded surface 16. Specifically, when the rotating vertical column 15 rotates forward, the threaded sleeve 18 rises, and when it rotates reversely, the threaded sleeve 18 falls. The combination of the first motor 14 and the threaded transmission realizes precise adjustment of the spraying height, and the spraying position can be flexibly adjusted according to the growth stage of the crop to avoid uneven spraying due to improper height (such as liquid drift when it is too high and insufficient coverage when it is too low).

[0063] The threaded sleeve 18 and the lifting frame plate 17 are an integrated structure, so the up and down movement of the threaded sleeve 18 will drive the lifting frame plate 17 to rise and fall synchronously, and the integrated design of the lifting frame plate 17 and the threaded sleeve 18 reduces the number of transmission components and reduces the probability of failure. Afterwards, the lifting frame plate 17 is fixedly connected to the rotating platform 33 through the lifting frame platform 23, and finally drives the steering and swinging mechanism, the spraying mechanism, the hard pipe 9 and the spray head 11 to rise and fall as a whole; during the lifting process, the second motor 22 is installed in the equipment groove 21 of the lifting frame plate 17, and moves synchronously with the lifting frame plate 17 to ensure that its connection with the rotating ring body 25 is always stable, so as not to affect the normal operation of the steering and swinging mechanism. The linkage design of the lifting mechanism and the steering and swinging mechanism also ensures the coordinated operation of "height adjustment + angle swing", further improving the comprehensiveness of the spraying coverage.

[0064] Example 2, based on the above example:

[0065] It should be further noted that, in order to maintain the stability of the lifting mechanism during the lifting process, a sliding groove 19 is formed on the surface of the vertical support 12 on the side close to the steering and swinging mechanism. A sliding plate 20 is slidably connected to the interior of the sliding groove 19, and the sliding plate 20 is fixedly connected to the inner wall of the lifting frame plate 17.

[0066] The length of the sliding groove 19 is consistent with that of the thread surface 16 .

[0067] Specifically, when the lifting mechanism is working, that is, the first motor 14 drives the rotating vertical column 15 to rotate, driving the lifting frame 17 to move up and down, the slide 20 fixed to the inner wall of the lifting frame 17 will slide synchronously along the sliding groove 19 on the surface of the vertical support 12:

[0068] When the lifting frame plate 17 rises, the slide plate 20 slides upward along the slide groove 19;

[0069] When the lifting frame plate 17 descends, the slide plate 20 slides downward along the slide groove 19;

[0070] At this point, the sliding cooperation between the slide plate 20 and the slide groove 19 provides horizontal limitation for the lifting frame plate 17, avoiding the lifting frame plate from deflecting or shaking due to the rotational force of the threaded transmission, thereby ensuring that the spraying mechanism remains vertically stable during the lifting process.

[0071] The length of the slide groove 19 is consistent with that of the threaded surface 16, ensuring that the sliding range of the slide plate 20 covers the entire lifting stroke of the lifting frame plate 17, further enhancing the smoothness of the lifting process, extending the service life of the threaded sleeve plate 18 and the threaded surface 16, and thus reducing wear caused by shaking.

[0072] It should be noted that the first motor 14, the second motor 22, and the thermostat 7 are all connected to the power supply circuit of the greenhouse body 1 and are controlled by an external timing controller to realize the coordinated operation of timed spraying, swinging, and lifting. The overall timed spraying operation process is as follows:

[0073] Water storage preparation: inject clean water or pesticide into the water storage tank 2 through the water inlet pipe 3. The water storage tank 2 is fixed to the roof of the greenhouse to facilitate gravity water supply;

[0074] Water temperature adjustment (optional): If the water temperature needs to be controlled, the thermostat 7 activates the heating pipe 6 to heat the water flowing out of the water storage tank 2, thereby maintaining the set temperature;

[0075] Timed start: The external timing device triggers the solenoid valve 5 to open, and water flows from the water storage tank 2 through the outlet pipe 4 into the heating pipe 6 (after heating), and then enters the spray mechanism through the telescopic hose 8;

[0076] Spraying operation: water passes through the telescopic hose 8 → the hard pipe 9 → the transfer shell 10, and is finally sprayed evenly from multiple spray heads 11;

[0077] Swing adjustment (optional): The second motor 22 drives the connecting flange 24 to rotate, driving the rotating ring 25 to rotate. The rotating ring 25 drives the rotating frame 32 to rotate and swing around the two ends of the limiting rotating column 34 through the arc plate 26, the adjustment connecting plate 29, the ball 37, the connecting rotating rod 31 and other structures. Finally, the hard pipe 9 and the sprinkler head 11 are driven to swing left and right through the driving rod 35 to expand the coverage area;

[0078] Height adjustment (optional): The first motor 14 drives the rotating vertical column 15 to rotate, and the threaded sleeve 18 moves up and down along the threaded surface 16, driving the lifting frame 17 and the spraying mechanism to rise and fall synchronously to adjust to the appropriate spraying height;

[0079] Timed closing: The timing device triggers the electromagnetic valve 5 to close, spraying stops, and a single timed spraying operation is completed.

[0080] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
