Description

Technical Field

[0001] This utility model belongs to the field of vegetable farming technology, and in particular relates to a multi-rail mobile spray humidification device for vegetable farming greenhouses. Background Technology

[0002] With the rapid development of facility agriculture, vegetable greenhouses, with their controllable environmental conditions, have effectively overcome the limitations of natural climate on vegetable cultivation, becoming a core carrier for ensuring year-round vegetable supply and improving yield and quality. Among these factors, air humidity, as a key environmental factor for vegetable growth, directly affects the efficiency of photosynthesis, the intensity of transpiration, and the probability of disease occurrence.

[0003] The inventors discovered that at least the following problems remain unsolved in the existing technology: traditional humidification devices mostly adopt a fixed installation mode, such as suspending the spray pipe at a certain position on the top of the greenhouse or laying it along the wall. The spray angle of the nozzle is fixed, which can only humidify a local area, resulting in obvious "humidification blind spots" in the greenhouse. The humidity in the area near the nozzle is too high, while the humidity in the area far away from the nozzle is insufficient, forming a significant humidity gradient difference.

[0004] To enhance the added value of humidification, growers often add foliar fertilizers, plant growth regulators, or low-concentration fungicides to the humidifying water to achieve a dual function of "humidification + maintenance." However, traditional devices often employ static storage designs, lacking effective stirring mechanisms. Solutes (such as foliar fertilizer granules and pesticide components) tend to settle at the bottom of the tank—after standing for one hour, the solute concentration at the bottom can be several times higher than that of the upper layer. When the device is running, the initial sprayed liquid is too low in solute content to achieve the desired maintenance effect, while the later sprayed liquid, with its excessively high solute concentration, can easily cause leaf burn and pesticide residue damage to vegetables, resulting in resource waste and posing a threat to vegetable quality and safety.

[0005] Therefore, we propose a multi-rail mobile spray humidification device for vegetable cultivation greenhouses, which can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a multi-rail mobile spray humidification device for vegetable greenhouses, which can achieve large-area uniform spraying and ensure stable solution concentration.

[0007] In view of this, the present invention provides a multi-rail mobile spray humidification device for vegetable cultivation greenhouses, including a shell and a slide rail. Spray pipes are horizontally and symmetrically arranged at the lower ends of both sides of the shell. Spray nozzles are equidistantly installed on the bottom side of the spray pipes. A slider is fixedly installed in the middle of the top of the shell. The slider is slidably connected to the slide groove on the bottom side of the slide rail. Electric rollers are rotatably connected to both sides of the inner wall of the bottom end of the slide groove. The two sides of the slider are tumblingly connected to the electric rollers on both sides of the slide groove.

[0008] The lower end of the housing is provided with a drive mechanism for driving the two sets of nozzles to swing back and forth.

[0009] The upper part of the shell is provided with a liquid storage chamber, and the liquid storage chamber is equipped with a stirring component for uniform mixing of the sprayed liquid inside the liquid storage chamber.

[0010] Furthermore, the drive mechanism includes a control block for pushing the nozzle to swing, and a crank connecting rod for driving the front and rear ends of the control block. The middle of the inner wall of the top and bottom of the liquid storage tank is rotatably connected to the drive rod through a sealed bearing. The bottom of the liquid storage tank is provided with a mounting groove. A flywheel is fixedly installed on one end of the drive rod placed inside the mounting groove. One end of the lower surface of the flywheel is hinged to the middle of the rear side of the control block through the crank connecting rod. The end of the drive rod away from the flywheel is fixedly connected to the middle of the bottom side of the gear. A rack is welded to the inner wall of one side of the slide groove, and the gear meshes with the rack.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1 to 4A multi-rail mobile spray humidification device for vegetable cultivation greenhouses includes a housing 1 and a slide rail 15. Spray pipes 11 are horizontally and symmetrically arranged at the lower ends of both sides of the housing 1. Nozzles 12 are equidistantly installed on the bottom side of the spray pipes 11. A slider 14 is fixedly installed in the middle of the top of the housing 1. The slider 14 is slidably connected to the slide groove 16 on the bottom side of the slide rail 15. Electric rollers 17 are rotatably connected to both sides of the inner wall of the bottom end of the slide groove 16. The two sides of the slider 14 are tumblingly connected to the electric rollers 17 on both sides of the slide groove 16. A drive mechanism is provided at the lower end of the housing 1 to drive the two sets of spray pipes 11 to swing back and forth. A liquid storage chamber 13 is opened at the upper end of the interior of the housing 1. A stirring assembly is provided inside the liquid storage chamber 13 for uniform mixing of the sprayed liquid inside the liquid storage chamber 13.

[0027] The slide rail 15 is slidably connected to the slider 14 at the top of the housing 1 via the slide groove 16 on the bottom side of the slide rail 15. The electric roller 17 can drive the housing 1 and the spray nozzle 11 to move horizontally on the bottom side of the slide rail 15 for spraying operations. The drive mechanism at the bottom of the housing 1 can automatically drive the two sets of spray nozzles 11 to swing back and forth, optimizing the spray angle and coverage uniformity. At the same time, the stirring component in the liquid storage tank 13 at the top of the housing 1 can continuously stir the sprayed liquid to avoid solute precipitation, ensure uniform concentration of the sprayed liquid, and ensure humidification effect and stable vegetable growth environment.

[0028] Furthermore, the drive mechanism includes a control block 25 for pushing the nozzle 11 to swing, and a crank connecting rod 26 for driving the front and rear ends of the control block 25. The middle of the inner wall of the top and bottom of the liquid storage tank 13 is rotatably connected to the drive rod 21 through a sealed bearing. The bottom end of the liquid storage tank 13 is provided with a mounting groove 2. A flywheel disk 24 is fixedly installed on one end of the drive rod 21 inside the mounting groove 2. One end of the lower surface of the flywheel disk 24 is hinged to the middle of the rear side of the control block 25 through the crank connecting rod 26. The end of the drive rod 21 away from the flywheel disk 24 is fixedly connected to the middle of the bottom side of the gear 22. A rack 23 is welded to the inner wall of one side of the slide groove 16. The gear 22 meshes with the rack 23.

[0029] When the housing 1 moves with the slider 14, the gear 22 at the top of the drive rod 21 meshes with the rack 23 on the inner wall of the slide groove 16. The reaction force of the rack 23 drives the gear 22 to rotate, which in turn drives the drive rod 21 to rotate synchronously. One end of the drive rod 21 extends into the mounting groove 2 and fixes the flywheel 24. The flywheel 24 is hinged to the control block 25 through the crank connecting rod 26. When the flywheel 24 rotates, the crank connecting rod 26 converts the rotational motion into the reciprocating linear motion of the control block 25. The control block 25 then pushes the two sets of nozzles 11 to swing back and forth, realizing the synchronous linkage between the movement of the housing 1 and the swing of the nozzles 11. No additional swing power source is required, which simplifies the structure and improves the comprehensiveness of humidification.

[0030] Furthermore, a rotating groove 34 is vertically opened through the middle of the slider 14, and the drive rod 21 is rotatably connected to the rotating groove 34.

[0031] It can prevent the drive rod 21 from deviating or shaking when rotating, ensuring that its top gear 22 and rack 23 are always stably meshed, avoiding transmission jamming; at the same time, it ensures that the drive rod 21 transmits the rotational power of the gear 22 to the lower flywheel disk 24, providing continuous and stable power for the nozzle 11 to swing, and maintaining the stable operation of the overall transmission system of the device.

[0032] Furthermore, the inner walls on both sides of the mounting groove 2 are provided with connection ports 27. The nozzle 11 is vertically fixedly installed above and below the side near the housing 1 with connecting rods 28. The connecting rods 28 above and below the nozzle 11 are rotatably connected to the connection ports 27 through bearings.

[0033] The connecting rod 28 is rotatably connected to the connecting port 27 via a bearing, providing a freely rotatable hinge fulcrum for the nozzle 11, ensuring that the nozzle 11 can swing back and forth.

[0034] Furthermore, the control block 25 has symmetrical control slots 29 on both sides, and the end of the nozzle 11 located inside the mounting slot 2 is movably connected to the control slot 29 on the outside of the control block 25.

[0035] When the drive mechanism drives the control block 25 to reciprocate linearly, the inner wall of the control groove 29 generates a pushing and pulling force on the nozzle 11 embedding end: when the control block 25 moves backward, the front inner wall of the control groove 29 pushes the nozzle 11 to swing forward; when the control block 25 moves forward, the rear inner wall of the control groove 29 pulls the nozzle 11 to swing backward, accurately converting the linear motion of the control block 25 into the reciprocating swing of the nozzle 11. Moreover, the size matching between the control groove 29 and the nozzle 11 embedding end can restrict the nozzle 11 and prevent the nozzle 11 from detaching from the control groove 29 during rotation.

[0036] Furthermore, a limiting block 35 is fixedly installed in the middle of the bottom side of the control block 25, and a limiting groove 36 is horizontally opened on the inner wall of the bottom end of the mounting groove 2. The limiting block 35 on the bottom side of the control block 25 is slidably connected to the limiting groove 36.

[0037] When the crank connecting rod 26 drives the control block 25 to move, the limiting groove 36 restricts the lateral displacement of the limiting block 35, allowing the control block 25 to move only in the front-back direction, preventing the control block 25 from shifting left or right or rotating due to uneven force, thus ensuring the stability of the drive mechanism.

[0038] Furthermore, the stirring assembly includes a disturbance rod 33 for stirring the sprayed liquid inside the liquid storage tank 13. The disturbance rod 33 is equidistantly installed on the outside of the drive rod 21, and the disturbance rod 33 is matched with the size of the liquid storage tank 13.

[0039] When the drive rod 21 rotates under the transmission of gear 22 and rack 23, it drives the disturbance rod 33 to rotate synchronously. During the rotation of the disturbance rod 33, it generates shear force on the sprayed liquid in the storage tank 13, causing the liquid at the bottom of the tank to flow upward and the liquid at the top to circulate downward, effectively preventing solute precipitation and ensuring that the concentration of the sprayed liquid in the storage tank 13 is uniform.

[0040] Furthermore, a water pump 3 is fixedly connected to the upper surfaces of both sides of the housing 1. The liquid extraction pipe 31 of the water pump 3 is connected to the bottom end of the liquid storage tank 13, and the liquid outlet hose 32 of the water pump 3 is connected to the spray pipe 11.

[0041] When the water pump 3 starts, a negative pressure is generated in the liquid extraction pipe 31 to draw the evenly stirred spray liquid in the chamber to the water pump 3; the water pump 3 pressurizes the extracted liquid to increase the liquid pressure to meet the transportation requirements; the pressurized liquid is transported to the nozzle 11 through the liquid outlet hose 32. The liquid outlet hose 32 has good flexibility and can swing back and forth with the nozzle 11 to deform freely without affecting the movement of the nozzle 11, continuously supplying liquid to the nozzle 11 and ensuring stable atomization spraying of the nozzle 12.

[0042] 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.
