Description

Technical Field

[0001] The invention relates to irrigation equipment, in particular to automatic irrigation equipment for flower seedling cultivation in plug trays, and belongs to the technical field of flower planting. Background Art

[0002] Flower plug tray seedling cultivation is a modern seedling cultivation technology. The seedlings in each hole of plug tray seedling cultivation are relatively independent, which reduces the spread of pests and diseases between each other and avoids the competition for nutrients among seedlings. The root system can fully develop, thereby improving the seedling rate and increasing the seedling density, facilitating intensive management, improving greenhouse utilization, and reducing production costs. At the same time, due to unified sowing and management, the growth and development of seedlings are consistent, which is conducive to large-scale production. During the planting process, in order to reduce manual labor, irrigation equipment is often used for irrigation.

[0003] At present, during the irrigation process, it is impossible to automatically adjust the spraying width according to the placement of the plug tray during transportation, which not only easily causes a waste of water resources, but also makes the irrigation area dirty. In addition, the plug trays are placed at intervals on the conveyor belt for transportation, and the conveying rate is not uniform. Therefore, a complex control system is required to control the irrigation, resulting in high production and use costs of the equipment.

[0004] Therefore, an automatic irrigation device for flower seedling cultivation in plug trays is designed to optimize the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide an automatic irrigation device for flower seedlings in plug trays. Conveyor belts are arranged on both sides of the top of the frame along the length direction, and push rods are evenly and vertically fixed on the surface of the conveyor belts. During use, thrust can be applied to the plug tray to control the side alignment of the plug tray for horizontal transportation. During the transportation process, a correction mechanism composed of a V-shaped plate, a slide rod, a limit plate, and a spring can be used to ensure that the plug tray is located in the middle position of the frame during transportation. In addition, a spray mechanism composed of a V-shaped plate, a spray trough, a spray head, a piston, a screw, a worm gear, a threaded groove, a worm, a gear, a rack, and a vertical rod is used. The vertical rod is vertically slidably connected to the V-shaped plate, and controls the movement of the piston inside the spray trough with the movement of the V-shaped plate, so as to automatically adjust the spray according to the length of the plug tray in the width direction of the frame during transportation. The width of the area can effectively avoid the waste of water resources while ensuring uniform spraying, and it is more practical. A switch control component consisting of a shaft rod, a torsion spring, a pressure plate, and a switch button is arranged on the inner side of the V-shaped plate. The switch button is electrically connected to the water pump on the water delivery mechanism through a wire. When the hole tray passes through the bottom of the V-shaped plate, the water pump can be automatically controlled to open for spray irrigation, and the water pump can be automatically turned off after the hole tray leaves, which makes the control more convenient. A smoothing mechanism consisting of a sweeping plate, a V-shaped spring sheet, and a rubber sheet is arranged on the inner sides of the two sets of side panels at the front end of the frame, and the ends of the sweeping plates on the two sets of side panels are fitted together. During the horizontal transportation of the hole tray, the rubber sheet can be fitted on the surface of the hole tray and slide, so that the matrix outside the planting hole on the surface of the hole tray can be swept into the inside of the hole, thereby improving the functionality of the device.

[0036] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. However, the implementation modes of the present invention are not limited thereto.

[0037] As Figure 1-Figure 7 As shown in the figure, this embodiment provides an automatic irrigation device for flower plug seedling raising, which includes a frame 1. On both sides of the top of the frame 1, conveyer belts 2 are arranged along the length direction. Push rods 3 are vertically fixed on the outer sides of the conveyer belts 2. The top of the conveyer belt 2 is lower than the horizontal plane of the top of the frame 1. Side plates 4 are fixed on both sides of the frame 1. The distance between the conveyer belt 2 and the adjacent side plate 4 is less than half of the width of the plug tray. The linear distance between adjacent conveyer belts 2 is less than half of the width of the plug tray. The width of the top of the frame 1 is greater than the length of the plug tray. A U-shaped frame 7 is arranged between two groups of side plates 4 at the end of the frame 1. Openings 701 are formed at both ends of the U-shaped frame 7. An electric telescopic rod 8 is installed on the top of the U-shaped frame 7. The output end of the electric telescopic rod 8 extends to the bottom of the U-shaped frame 7. A spraying mechanism 9 is installed at the output end of the electric telescopic rod 8. A correction mechanism 6 is arranged at the bottom of the U-shaped frame 7 and on the side of the side plate 4. A water conveying mechanism 10 for supplying water to the inside of the spraying mechanism 9 is arranged at the bottom of the frame 1. Smoothing mechanisms 5 are arranged on the inner sides of the two side plates 4 at one end of the frame 1 away from the U-shaped frame 7. A collecting mechanism 11 is arranged at one end of the frame 1 close to the U-shaped frame 7.

[0038] Overall working principle: After covering the substrate on the top of the plug tray and planting flower seeds, place the plug tray at one end of the frame 1 away from the U-shaped frame 7. The plug tray can be placed horizontally or vertically. Since the distance between the conveyer belt 2 and the adjacent side plate 4 is less than half of the width of the plug tray, and the linear distance between adjacent conveyer belts 2 is less than half of the width of the plug tray, after the plug tray is placed, with the start of the conveyer belt 2, the push rod 3 will move towards the direction of the plug tray. The push rods 3 on the two conveyer belts 2 will both fit against the end of the plug tray. Even if the plug tray is placed obliquely, the push rod 3 on one conveyer belt 2 will contact the plug tray first and apply a thrust to the plug tray to adjust the position of the plug tray until the two push rods 3 are simultaneously in contact with the surface of the plug tray, controlling the horizontal movement of the plug tray. During the movement of the plug tray, first use the smoothing mechanism 5 to sweep the substrate residue on the surface of the plug tray into the holes to ensure the cleanliness of the surface of the plug tray, and then use the correction mechanism 6 to correct the position of the plug tray and move the plug tray to the center of the top of the frame 1. When the plug tray moves to the bottom of the spraying mechanism 9, the water conveying mechanism 10 starts to supply water to the inside of the spraying mechanism 9. The spraying mechanism 9 automatically adjusts the width of the spraying area according to the length of the plug tray in the width direction of the frame 1 during transportation, and then evenly irrigates the top of the plug tray. After irrigation, the plug tray is pushed out, and the residue at the bottom of the plug tray will fall into the inside of the collecting mechanism 11 for storage when it is pushed out.

[0039] In this embodiment, the water delivery mechanism 10 includes a water tank 1001, a water pump 1002 and a water pipe 1003. The water tank 1001 is located at the bottom of the frame 1. The water pump 1002 is installed on the outside of the water tank 1001. The input end of the water pump 1002 is connected to the inside of the water tank 1001. The output end of the water pump 1002 is installed with a water pipe 1003 connected to the spray mechanism 9.

[0040] Partial working principle: When irrigation is performed, the water pump 1002 is started to extract the water source inside the water tank 1001 and then transport it to the inside of the spray mechanism 9 through the water pipe 1003.

[0041] In this embodiment, the correction mechanism 6 includes a V-shaped plate 601, a sliding rod 602, a limit plate 603, a spring 604, a roller 605 and a switch control component 606. The V-shaped plate 601 is symmetrically arranged on both sides of the top of the frame 1. The sliding rods 602 are fixedly installed on the inner sides of the V-shaped plate 601. The sliding rods 602 all penetrate the side plates 4 and are slidably connected with the side plates 4. The limit plates 603 are fixed between the ends of the sliding rods 602 away from the V-shaped plate 601. Springs 604 are installed between the limit plates 603 and the outer sides of the side plates 4. The end of the V-shaped plate 601 away from the cam frame 7 is open outward, and the end of the V-shaped plate 601 close to the cam frame 7 is parallel to the length direction of the frame 1. The outer side of the V-shaped plate 601 close to the cam frame 7 is evenly rotated and installed with rollers 605. A switch control component 606 for controlling the water pump 1002 is provided on the outer side of the V-shaped plate 601 and between the rollers 605.

[0042] Local working principle: when two sets of push rods 3 contact the side of the hole tray at the same time and push the hole tray to move, if the hole tray is not centered, one corner of the hole tray will first contact the inclined surface of the V-shaped plate 601, and the inclined surface will guide the hole tray and apply a longitudinal thrust until it contacts the other V-shaped plate 601. Then the movement of the hole tray will simultaneously apply an outward thrust to the two sets of V-shaped plates 601. At this time, the V-shaped plates 601 move outward and stretch the springs 604 to fit the hole tray tightly between the horizontal surfaces of the two sets of V-shaped plates 601. The hole tray is centered. During the movement of the hole tray, the switch control component 606 is triggered to automatically turn on the water pump 1002 to perform irrigation operations.

[0043] In this embodiment, the switch control component 606 includes a shaft 6061, a torsion spring 6062, a pressure plate 6063 and a switch button 6064. The shaft 6061 is vertically rotatably installed on the outer side of the V-shaped plate 601. Torsion springs 6062 are installed at both ends of the shaft 6061. A pressure plate 6063 is installed at the middle position of the shaft 6061, and the pressure plate 6063 is inclined toward the direction of the clamp 7. A switch button 6064 is installed on the outer side of the V-shaped plate 601 near the inclined side of the pressure plate 6063. The switch button 6064 is electrically connected to the water pump 1002 through a wire.

[0044] Partial working principle: During the movement of the hole tray, when the front end of the hole tray is facing the bottom of the spray mechanism 9, the hole tray squeezes the pressure plate 6063, and the pressure plate 6063 squeezes the switch button 6064, thereby controlling the start of the water pump 1002 to perform irrigation operations. When the irrigation is completed, the hole tray no longer contacts the pressure plate 6063, and the irrigation stops automatically.

[0045] In this embodiment, the spray mechanism 9 includes a shaped plate 901, a spray slot 902, a nozzle 903, a piston 904 and a telescopic component. The top of the shaped plate 901 is connected to the output end of the electric telescopic rod 8. The spray slot 902 is opened at the top of the shaped plate 901 along the length direction of the shaped plate 901. The top of the water pipe 1003 is connected to the inside of the spray slot 902. The nozzles 903 connected to the inside of the spray slot 902 are evenly installed on the inner bottom of the shaped plate 901 along the length direction. Pistons 904 are slidably installed at both ends of the inside of the spray slot 902, and telescopic components for controlling the sliding of the piston 904 are provided at the ends of the shaped plate 901.

[0046] Local working principle: Before the process of spray irrigation, the telescopic component is first used to control the piston 904 to slide inside the spray groove 902, and the width of the spray area is automatically adjusted according to the length of the plug tray in the width direction of the frame 1 during transportation. The spacing between the two groups of pistons 904 is the same as the length of the plug tray in the width direction of the frame 1. The water delivered by the water pump 1002 enters the interior of the spray groove 902, and then is discharged from the nozzle 903 to evenly irrigate the surface of the plug tray.

[0047] In this embodiment, the telescopic assembly includes a screw 905, a worm wheel 906, a thread groove 907, a worm 908 and a rotating portion. The screw 905 is fixed to the end of the piston 904, and the screw 905 extends to the outer end of the piston 904. The worm wheels 906 are rotatably installed at both ends of the convex plate 901. The middle position of the worm wheel 906 is provided with a thread groove 907, and the screw 905 passes through the inside of the thread groove 907. The outer side of the worm wheel 906 and the end of the convex plate 901 are vertically rotatably installed with a worm 908, which is meshed with the worm wheel 906, and the bottom end of the worm 908 is provided with a rotating portion.

[0048] Local working principle: when controlling the movement of piston 904, the rotating part is used to control the rotation of worm 908. The rotation of worm 908 drives worm wheel 906 to rotate. Since piston 904 is rectangular in shape, piston 904 will not rotate inside spray tank 902. The rotation of worm wheel 906 will control the horizontal movement of screw 905, thereby controlling the position of piston 904. The transmission method of worm wheel 906 and worm 908 has a self-locking function, which can effectively prevent piston 904 from sliding outward due to excessive water pressure inside spray tank 902, thereby ensuring the stability of the position of piston 904.

[0049] In this embodiment, the rotating part includes a gear 909, a rack 9010, and a vertical rod 9011. The gear 909 is fixedly installed at the bottom end of the worm 908. The end of the V-shaped plate 901 is slidably installed with a rack 9010 meshing with the gear 909 along the length direction. The vertical rod 9011 is fixed at one end of the rack 9010 located at the bottom of the V-shaped plate 901, and the bottom end of the vertical rod 901 is vertically slidably connected to the V-shaped plate 601.

[0050] Partial working principle: When the V-shaped plate 601 corrects the position of the hole tray, it will move outward. The movement of the V-shaped plate 601 will drive the vertical rod 9011 to move longitudinally, and then drive the rack 9010 to move. The movement of the rack 9010 will control the rotation of the gear 909, and then control the rotation of the worm 908.

[0051] In this embodiment, the smoothing mechanism 5 includes a sweeping plate 501, a V-shaped spring piece 502 and a rubber sheet 503. The sweeping plate 501 is hingedly mounted on the inner side of the side plate 4. The distance between the bottom end of the sweeping plate 501 and the top of the frame 1 is greater than the height of the hole tray. The ends of the sweeping plates 501 on the inner sides of the two groups of side plates 4 fit together. V-shaped spring pieces 502 are provided between the inner side of the sweeping plate 501 and the side plate 4. A rubber sheet 503 is provided at the bottom of the sweeping plate 501 along the length direction.

[0052] Partial working principle: When the push rod 3 controls the translation of the hole tray, the rubber sheet 503 at the bottom of the sweeping plate 501 contacts the surface of the hole tray, and can guide the matrix on the surface of the hole tray to the inside of the hole, and clean the surface of the hole tray.

[0053] In this embodiment, the collecting mechanism 11 includes a collecting box 1101, a scraper 1102 and a strip groove 1103. The collecting box 1101 is fixed at the end of the frame 1. The scraper 1102 is obliquely arranged on the top of the collecting box 1101, and the top of the collecting box 1101 is in contact with the end of the frame 1. The scraper 1102 is provided with a strip groove 1103 that cooperates with the push rod 3.

[0054] Partial working principle: During use, the substrate sliding down from the end of the frame 1 will pass through the scraper 1102 and enter the interior of the collection box 1101 for storage.
