Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, specifically an irrigation mechanism for agricultural greenhouses. Background Technology

[0002] Agricultural greenhouses are an important agricultural facility, mainly used for protected cultivation. They have functions such as heat preservation, yield increase, and off-season planting. The application of plastic film began in the 1950s. Japan and European and American countries were the first to achieve success in covering greenhouse beds. my country introduced polyvinyl chloride agricultural film in 1955 for covering vegetables in small greenhouses, with remarkable results.

[0003] Currently, agricultural greenhouses commonly use fixed sprinklers for irrigation. However, this design has significant limitations. Because the sprinkler positions cannot be adjusted, irrigation blind spots are easily created in actual use, especially in the following two situations: First, when crops enter different growth stages and their plant height changes, the originally designed spraying range may not be able to effectively cover them; second, when growers adjust crop layouts or change crop varieties, the spraying pattern of fixed sprinklers is often difficult to match with the new planting density and spatial distribution. These situations can lead to insufficient water supply or over-irrigation in some areas, affecting irrigation uniformity and water resource utilization efficiency. Therefore, an irrigation mechanism for agricultural greenhouses is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-7 As shown, an irrigation mechanism for agricultural greenhouses includes a frame 1; connecting plates 2 are provided on both side walls of the frame 1; a connecting rod 3 is fixedly connected between a pair of connecting plates 2; a sliding groove 4 is provided on the side wall of the connecting rod 3; a slider 5 is slidably connected to the groove wall of the sliding groove 4; a reciprocating component is provided on the side wall of the slider 5; a water pipe 6 is fixedly connected to the side wall of the slider 5; an inlet pipe 7 is fixedly connected to the outer circular wall of the water pipe 6; and a nozzle 8 is fixedly connected to one end of the water pipe 6. During operation, water enters the water pipe 6 through the inlet pipe 7, and then enters the nozzle 8 through the water pipe 6. With the frame 1 above the irrigation area, the nozzle 8 irrigates from top to bottom. Under the action of the reciprocating component, the slider 5 drives the nozzle 8 to move back and forth on the frame 1 through the water pipe 6. The moving nozzle 8 adjusts the spraying position, eliminating blind spots in irrigation, ensuring that each crop receives the same water and fertilizer supply, and improving irrigation efficiency.

[0025] The reciprocating component includes a reciprocating screw 9; a pair of connecting plates 2 are rotatably connected to the reciprocating screw 9; a sliding block 10 is slidably connected in the bidirectional spiral groove of the reciprocating screw 9; the sliding block 10 is rotatably connected to the slider 5; a motor 11 is fixedly connected to the side wall of one of the pair of connecting plates 2; a rotating shaft is fixedly connected to the output end of the motor 11; the rotating shaft is fixedly connected to the reciprocating screw 9; during operation, the output end of the motor 11 drives the rotating shaft to rotate, thereby the rotating shaft drives the reciprocating screw 9 to rotate. When the reciprocating screw 9 rotates, the sliding block 10 automatically reverses direction under the alternating action of the spiral grooves with opposite rotation directions, forming a periodic reciprocating motion. Thus, the sliding block 10 drives the slider 5 to reciprocate in the sliding groove 4 of the connecting rod 3, and then the slider 5 drives the nozzle 8 on the water pipe 6 to move, realizing the effect of the nozzle 8 reciprocating on the frame 1.

[0026] A rack 12 is fixedly connected between a pair of connecting plates 2; one end of the water pipe 6 is rotatably connected to a receiving pipe 13; one end of the receiving pipe 13 is provided with a nozzle 8; a gear 14 is fixedly connected to the outer circular wall of the receiving pipe 13; the gear 14 meshes with the rack 12; during operation, through the meshing between the rack 12 and the gear 14, when the water pipe 6 moves with the slider 5, the water pipe 6 will drive the receiving pipe 13 to move. Since the receiving pipe 13 can rotate on the water pipe 6, and the gear 14 on the receiving pipe 13 meshes with the rack 12 on the connecting plate 2, when the receiving pipe 13 moves, the gear 14 will drive the receiving pipe 13 to rotate on the water pipe 6. In this way, the receiving pipe 13 will drive the nozzle 8 to rotate, increasing the coverage area of ​​the nozzle 8, increasing the humidity in the greenhouse, and effectively preventing leaf diseases.

[0027] The outer circular wall of the receiving pipe 13 is provided with an L-shaped groove 15; an L-shaped block 16 is fixedly connected to the side wall of the nozzle 8; the L-shaped block 16 matches the L-shaped groove 15; the groove wall of the L-shaped groove 15 is provided with a limiting groove 18; a locking block 17 is slidably connected to the groove wall of the limiting groove 18; the side wall of the L-shaped block 16 is provided with a locking groove 19; the locking groove 19 matches the locking block 17; a spring is fixedly connected between the locking block 17 and the limiting groove 18; during operation, by pulling the locking block 17, the operator can disengage the locking block 17 from the locking groove 19, and then rotate the nozzle 8 to disengage the transverse block of the L-shaped block 16 from the transverse groove of the L-shaped groove 15. The operator can then directly move the nozzle 8 downwards to disengage it from the receiving pipe 13, enabling quick installation and removal of the nozzle 8 on the receiving pipe 13, facilitating maintenance and replacement of different models of nozzle 8.

[0028] The frame 1 is slidably connected to the connecting plate 2; an extension rod 20 is fixedly connected to the side wall of the frame 1; a threaded rod 21 is rotatably connected to the side wall of the extension rod 20; a threaded block 22 is threadedly connected to the outer circular wall of the threaded rod 21; one of the pair of connecting plates 2 is fixedly connected to the threaded block 22; during operation, the operator rotates the threaded rod 21, thereby the rotation of the threaded rod 21 drives the threaded block 22 to rise or fall, and then the threaded block 22 drives the connecting plate 2 to move up and down. In this way, the operator can rotate the threaded rod 21 to adjust the height of the nozzle 8 to adapt to crops at different growth stages.

[0029] A handle is fixed to one end of the threaded rod 21; during operation, the operator can smoothly and conveniently operate the threaded rod 21 through the handle on the threaded rod 21.

[0030] Working principle: Water enters through the inlet pipe 7 and then through the water pipe 6, where it flows into the sprinkler head 8. With the frame 1 positioned above the irrigation area, the sprinkler head 8 irrigates from top to bottom. Under the action of the reciprocating mechanism, the slider 5 drives the sprinkler head 8 to move back and forth on the frame 1 via the water pipe 6. This movement of the sprinkler head 8 adjusts the spraying position, eliminating blind spots and ensuring each crop receives the same water and fertilizer supply, thus improving irrigation efficiency. The output of the motor 11 drives the rotating shaft, which in turn drives the reciprocating screw 9. When the reciprocating screw 9 rotates, the sliding block 10 automatically reverses direction under the alternating action of the helical grooves in opposite directions, forming a periodic reciprocating motion. This causes the sliding block 10 to drive the slider 5 to reciprocate within the groove 4 of the connecting rod 3. Subsequently, the slider 5 drives the nozzle 8 on the water pipe 6 to move, achieving the effect of the nozzle 8 reciprocating on the frame 1. Through the meshing between the rack 12 and the gear 14, as the water pipe 6 moves with the slider 5, the water pipe 6 drives the receiving pipe 13 to move. Since the receiving pipe 13 can rotate on the water pipe 6, and the receiving pipe 13... The gear 14 on the upper part meshes with the rack 12 on the connecting plate 2, so that when the receiving pipe 13 moves, the gear 14 will drive the receiving pipe 13 to rotate on the water pipe 6. In this way, the receiving pipe 13 will drive the nozzle 8 to rotate, increasing the coverage area of ​​the nozzle 8, increasing the humidity in the greenhouse, and effectively preventing leaf diseases. After the operator pulls the locking block 17 to disengage the locking block 17 from the locking groove 19, the operator can rotate the nozzle 8. After the horizontal block of the L-shaped block 16 disengages from the horizontal groove of the L-shaped groove 15, the operator can directly turn the nozzle 8 downward. The nozzle 8 can be quickly installed and removed from the receiving pipe 13, facilitating maintenance and replacement of different models of nozzle 8. By rotating the threaded rod 21, the screw of the threaded rod 21 drives the threaded block 22 to rise or fall, which in turn drives the connecting plate 2 to move up and down. In this way, the operator can rotate the threaded rod 21 to adjust the height of the nozzle 8 to adapt to crops at different growth stages. The handle on the threaded rod 21 allows the operator to operate the threaded rod 21 smoothly and conveniently.
