[0021] Example 1

[0022] A synchronous quantitative hole watering device for direct seeding of rice comprises a water supply mechanism, a water pipe 3, a control mechanism, a branch water pipe 4, a synchronous watering wheel 5 and a water wheel bracket assembly, wherein the water supply mechanism is connected to the control mechanism via the water pipe 3, the control mechanism is connected to at least two branch water pipes 4, the synchronous watering wheel 5 is installed on the water wheel bracket assembly, the water wheel bracket assembly supplies water via the branch water pipe 4, and the water wheel bracket assembly supplies water to the synchronous watering wheel 5.

[0023] The water supply mechanism includes a water tank 1 and a water pump 2. The output end of the water tank 1 is connected to the water pump 2 through a pipe. The output end of the water pump 2 is connected to the water pipe 3. The water is delivered to the water pipe 3 by the pressure of the water pump 2. The water wheel bracket assembly includes at least one hollow tube 8 and a pair of positioning long plates 9. For example, two hollow tubes 8 and two pairs of positioning long plates 9 are used. One hollow tube 8 and a pair of positioning long plates 9 constitute a group. A hollow tube 8 is fixed between a pair of positioning long plates 9. Both ends of the hollow tube 8 are connected to branch water pipes 4. The branch water pipes 4 can be hoses. Water is input to both ends of the hollow tube 8. On the hollow tube 8, a branch water pipe 4 is connected to the branch water pipe 4. The branch water pipe 4 can be a hose. Water is input to both ends of the hollow tube 8. At least one rotatably connected synchronous watering wheel 5 is installed in the hollow tube 8. The rotating structure can be a circular sealing ring designed at the connection between the two ends of the synchronous watering wheel 5 and the hollow tube 8, which can ensure a certain sealing and a certain rotation. In order to prevent the synchronous watering wheel 5 from shaking left and right, a limit ring can also be designed at both ends; in this embodiment, two synchronous watering wheels 5 can be designed at intervals, and the spacing can be adjusted. The hollow tube 8 can be a metal tube, which serves as the rotating shaft of the synchronous watering wheel 5 on the one hand, and as a water pipe 3 to transport water to the synchronous watering wheel 5 on the other hand. The synchronous watering wheel 5 can rotate on the hollow tube 8 as the seeder moves.

[0024] In this embodiment, at least one notch 11 is provided on the hollow tube 8, and the actual number of notches 11 corresponds to the synchronous watering wheel 5. The notch 11 is located inside the synchronous watering wheel 5. Water can flow out of the notch 11 of the hollow tube 8 into the synchronous watering wheel 5, and then flow out through the water outlet 12 and be synchronously poured into the seed hole, thereby realizing synchronous hole watering.

[0025] In this embodiment, a plurality of evenly spaced water outlet holes 12 are provided on the circular front of the synchronous watering wheel 5, so that water can be evenly circulated. For example, 4-6 evenly spaced water outlet holes 12 are provided on the circular front of the synchronous watering wheel 5.

[0026] In this embodiment, a toothed disc 10 is installed on one side of the synchronous watering wheel 5, which is used to synchronously drive other devices on the seed drill to move. For example, the toothed disc 10 on one side of the synchronous watering wheel 5 is connected to the toothed disc 10 of the corresponding seeding wheel through a chain. The rotation of the seeding wheel can drive the synchronous watering wheel 5 to rotate, or the synchronous watering wheel 5 can drive the rotation of the seeding wheel to achieve synchronous hole watering. The diameter and number of teeth of the toothed disc 10 of the seeding wheel and the synchronous watering wheel 5 are designed according to a certain ratio, so that the water outlet 12 of the synchronous watering wheel 5 is synchronously aligned with the seeding hole. The circumference of the seeding wheel and the watering wheel must be an integer multiple of the seeding hole distance. If the number of seeding hole mouths of the seeding disk is N, the radius is R, and the number of teeth of the toothed disc 10 is M, and the number of water outlet holes 12 of the synchronous watering wheel 5 is n, the radius is r, and the number of teeth of the toothed disc 10 is m, then m=nM / N=rM / R. The structure of the seeding wheel is not described in detail in this embodiment.

[0027] In this embodiment, the control mechanism includes a main control valve 6 and several auxiliary control valves 7. The main control valve 6 is connected to the branch water pipe 4 through a water distribution pipe. An auxiliary control valve 7 is installed at the output end of each branch water pipe 4. During operation, the main control valve 6 and the corresponding auxiliary control valve 7 are opened to transport water to the corresponding branch water pipe 4, which is convenient for control.

[0028] The synchronous watering mechanism adopts a control mechanism and a branch water pipe 4 to supply water to the synchronous watering wheel 5. When the synchronous watering wheel 5 moves, it only waters each sowing hole quantitatively and evenly, and uses the least amount of water to the maximum extent to meet the needs of rice seed germination and emergence, so as to achieve full and strong seedlings in one sowing, and realize water saving in arid and water-deficient areas.

[0029] Example 2

[0030] In this embodiment, a small hole is opened on the upper side of the highest point of the water delivery pipe 3 of the water pump 2 above the ground, and then a thin tube 13 is arranged at the small hole. One end of the thin tube 13 is connected to the small hole, and the other end is inserted into the pre-opened hole on the top of the water tank 1. However, the pipe mouth must be above the water surface and cannot be inserted into the water to prevent the water in the water tank 1 from flowing out due to siphon phenomenon when the machine stops operating.
