[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0030] Example 1

[0031] See also Figure 1-5 As shown, a water scraping device for a seedling greenhouse comprises a greenhouse film 1, a water scraping mechanism, a water tank 7 and a water collecting mechanism. The water tank 7 and the greenhouse film 1 are both installed on the ground. An arc-shaped frame 2 is provided inside the greenhouse film 1 for installing the water scraping mechanism.

[0032] The wiper mechanism includes a slider 3, which is slidably connected to the arc frame 2. The surface of the slider 3 is movably connected to a traction rod 8 through a universal joint. The traction rod 8 is a retractable design.

[0033] The surface of the slider 3 is fixedly connected to a bracket 14, the surface of the bracket 14 is rotatably connected to a fixed shaft 13, the surface of the fixed shaft 13 is provided with a sponge 4, and both ends of the fixed shaft 13 are provided with end caps 5;

[0034] The water collection mechanism includes a water collection box 6, a card strip 16 is fixedly connected to the surface of the water collection box 6, and two card strips 16 are provided, one of which is movably connected to the surface of the bracket 14, and the other is movably connected to the surface of the end cover 5. A scraper 18 is fixedly connected to the water collection box 6, and the scraper 18 is in contact with the sponge 4. The bottom surface of the water collection box 6 is inclined.

[0035] The water collecting box 6 is provided with a drainage hole 9, the surface of the water tank 7 is provided with a water inlet pipe 15, and an opening and closing mechanism is provided in the drainage hole 9;

[0036] The surface of the water collecting box 6 is provided with a gravity mechanism, the surface of the scraper 18 is fixedly connected to the filter screen 17, the filter screen 17 is an arc shape with raised ends, the surface of the fixed shaft 13 is fixedly connected to the gear 12, the surface of the arc frame 2 is fixedly connected to the rack, and the gear 12 is meshed with the rack;

[0037] During operation, the staff pulls the slider 3 through the traction rod 8, so that the slider 3 slides on the surface of the arc frame 2, and at the same time the gear 12 on the surface of the fixed shaft 13 engages with the rack, so that the gear 12 rotates, and at the same time drives the fixed shaft 13 to rotate. Through the gear 12, when the slider 3 slides upward, the fixed shaft 13 rotates clockwise, which plays a wiping action, making the cleaning effect of the sponge 4 better. When the slider 3 moves, due to the action of gravity, and the water collection box 6 is movably connected to the bracket 14 and the surface of the end cover 5 through the card strip 16, the weight is matched. The force structure water collecting box 6 will always be under the sponge 4. When the sponge 4 rotates, the water on the surface of the sponge 4 will be scraped off by the scraper 18 to avoid the problem of the absorbent sponge 4 being saturated with water, and the greenhouse film 1 can be continuously cleaned. There is no need for the staff to return to the squeezing box to squeeze the absorbent sponge 4 to drain the water and then clean it again, which greatly improves the cleaning efficiency. Finally, the water in the water collecting box 6 is discharged into the water tank 7 through the drainage hole 9. The bottom of the water collecting box 6 is designed to be inclined, which can make the water gather in the middle, thereby making the water discharge faster and more thorough.

[0038] The gravity mechanism is a magnetic block 11, and the surface of the magnetic block 11 is provided with an arc angle. The magnetic block 11 is slidably connected to the outer wall of the water collecting box 6 by a spring. A positioning ring 10 is fixedly connected to the surface of the water tank 7 relative to the position of the magnetic block 11, and a magnetic block 11 is also provided inside the positioning ring 10.

[0039] During operation, when the water collecting box 6 reaches above the water tank 7, the principle of out-of-phase attraction between the magnetic blocks 11 will force the water collecting box 6 to be perpendicular to the water tank 7. Then, when the water collecting box 6 continues to move downward, the magnetic block 11 will be stuck in the ring through the arc surface on the surface. Then, the water collecting box 6 continues to move downward, and the magnetic block 11 cooperates with the ring to play a positioning role, thereby facilitating the docking of the drainage hole 9 with the water inlet pipe 15. Finally, the water in the water collecting box 6 is discharged into the water tank 7 through the drainage hole 9.

[0040] The opening and closing mechanism includes a sliding shaft 20, which is slidably connected in the drain hole 9 by a spring. A sealing plate 21 is fixedly connected to the surface of the sliding shaft 20, and a sealing ring is fixedly connected to the surface of the sealing plate 21. A top shaft 19 is fixedly connected in the water inlet pipe 15.

[0041] During operation, when the staff controls the slider 3 to approach the water tank 7, the drainage hole 9 on the surface of the water tank 7 will be inserted into the water inlet pipe 15. At this time, the top shaft 19 in the water inlet pipe 15 will squeeze the sliding shaft 20 to move upward, so that the sliding shaft 20 drives the sealing plate 21 to move upward, so that the sealing plate 21 releases the blockage of the drainage hole 9, and then the water in the water collecting box 6 will flow into the water tank 7 for storage. The stored water can be reused for irrigation to avoid waste.

[0042] Example 2

[0043] See also Figure 6 As shown, in contrast to Example 1, as another implementation of the present invention, the end cover 5 is fixedly mounted on the surface of the fixed shaft 13 through a threaded connection, and the sponge 4 is mounted on the fixed shaft 13 through a keyway; during operation, the sponge 4 roller can be disassembled and replaced through the threaded end cover 5, so as to avoid the water absorption effect of the sponge 4 decreasing after a long period of use, resulting in a decrease in the cleaning effect of the greenhouse film 1. The sponge 4 is mounted on the fixed shaft 13 through a keyway, which can avoid the situation where the fixed shaft 13 rotates while the sponge 4 does not rotate.
