The first embodiment is as follows:

referring to fig. 1-9, the present invention provides a device for quantitative irrigation in hole application, which comprises a box body 1, a box cover 2, a liquid level control mechanism 3, a quantitative irrigation mechanism 5 and an irrigation start/stop mechanism. A partition plate 11 is arranged in the box body 1, and the partition plate 11 divides the inner cavity of the box body 1 into a water storage chamber 12 and an irrigation chamber 13. The bottom of the partition plate 11 is provided with a water replenishing port 15, and the water storage chamber 12 is communicated with the irrigation chamber 13 through the water replenishing port 15. The lid is also provided with a water injection port (not shown) located above the reservoir 12. The bottom of the irrigation chamber 13 is provided with two irrigation holes 14, and each irrigation hole 14 is internally provided with a permeable pore plate for permeable drainage to the outside of the box body 1. Division board 11 is close to and is equipped with irrigation room 13 one side liquid level regulation and control mechanism 3 please refer to fig. 2-6, liquid level regulation and control mechanism 3 includes floater 31, dwang 32, sliding sleeve 33 and dog 34, dwang 32 middle part is articulated with box 1, dwang 32 is kept away from moisturizing mouth 15 one end and is equipped with floater 31, dwang 32 is close to moisturizing mouth 15 one end and is equipped with sliding sleeve 33, sliding sleeve 33 and dwang 32 sliding connection, sliding sleeve 33 bottom is articulated with dog 34 top, dog 34 and division board 11 sliding connection, just dog 34 corresponds with moisturizing mouth 15 positions. Specifically, the floating ball 31 fluctuates up and down along with the liquid level in the irrigation chamber 13, and then the rotating rod 32 and the sliding sleeve 33 drive the stopper 34 to slide up and down, so as to open or close the water replenishing port 15. Referring to fig. 5, when the water source in the irrigation chamber 13 is sufficient, the liquid level is high, so that the floating ball 31 floats upwards, and the stopper 34 is pressed down by the rotating rod 32 to close the water inlet 15; referring to fig. 6, when the water supply in the irrigation chamber 13 is insufficient, the liquid level drops, the floating ball 31 sinks, the stopper 34 is lifted by the rotating rod 32 to open the water inlet 15, and the water storage chamber 12 supplies water to the irrigation chamber 13. Referring to fig. 8-9, the quantitative irrigation mechanism 5 includes a first screw 51, a pressing plate 53, a tension spring 54 and a sealing block 59, the first screw 51 is connected to the box cover 2 by a thread, the pressing plate 53 is located below the first screw 51, the pressing plate 53 is hung on the bottom surface of the box cover 2 by the tension spring 54, the sealing block 59 is arranged on the bottom surface of the pressing plate 53, and the sealing block 59 corresponds to one of the irrigation openings 14. As the growth period and season of the fruit tree change, the irrigation amount of the fruit tree needs to be adjusted adaptively, so that the quantitative irrigation mechanism 5 is adopted to abut against and push the pressure plate 53 to press downwards by rotating the first screw 51 when needed, so that the sealing block 59 on the bottom surface of the pressure plate 53 closes one of the irrigation openings 14, and the irrigation amount is reduced. The irrigation starting and stopping mechanism comprises a third screw rod 6, the third screw rod 6 is in threaded connection with the box cover 2, and the third screw rod 6 is located above the stop block 34. When the fruit tree does not need irrigation, such as in rainy season, the stop block 34 is pressed down by screwing the third screw 6 to close the water replenishing port 15, so that the liquid level regulating mechanism 3 is disabled, and the irrigation is stopped after residual water in the irrigation chamber 13 is discharged. Preferably, handles are connected to the rod bodies of the first screw and the third screw extending out of the box cover 2, so as to facilitate screwing the screws.

Example two:

compared with the first embodiment, the present embodiment sets the irrigation openings to at least three. Referring to fig. 7-13, the quantitative irrigation mechanism 5 further includes a pressing cylinder 52, a second screw 55, a rotating block 56, a pressing rod 57 and an annular plate 58.

Referring to fig. 8-11, when the second screw 55 rotates and moves downward relative to the first screw 51, the two pressing rods 57 extend to the outside of the pressing cylinder 52 under the thrust of the limiting groove 521, the turning block 56 and the second screw 55. Referring to fig. 13, first, the first screw 51 moves upward and is separated from contact with the pressing plate 53, specifically, a blind hole is formed on the periphery of the first screw 51, and when the first screw is screwed to move upward and the blind hole exceeds the box cover, the first screw is separated from contact with the pressing plate; then screwing the second screw 55 to move downwards to extend the pressure rod 57; then screwing the first screw 51 to move downwards to enable one end of the pressure rod 57 far away from the second screw 55 to abut against the annular plate 58; the first screw 51 is continuously screwed to move downwards to press the pressure plate 53 and the annular plate 58 downwards, so that the sealing blocks 59 below the pressure plate 53 and the sealing blocks 59 below the annular plate 58 simultaneously seal at least two irrigation openings 14, further changing the irrigation amount and realizing more accurate adjustment of the irrigation amount.

As a further improvement to the second embodiment, 9 irrigation openings are provided, and the 9 irrigation openings are arranged in a grid pattern, as shown in fig. 4, wherein the cross-sectional area of the irrigation opening located in the center is 2 times that of the irrigation openings located at the outer side 8, and the bottom surface of the annular plate 58 is provided with 3 sealing blocks. When the pressure rod 57 is accommodated in the pressure cylinder 52, the first screw 51 is screwed to press the pressure plate 53 only to close the central irrigation opening, so that the irrigation amount of the irrigation chamber 13 is reduced 1/5, as shown in fig. 12; when the pressing rod 57 extends out of the pressing cylinder 52, the first screw 51 is screwed to press the pressing plate 53 and the annular plate 58 downward at the same time, so as to close 4 irrigation openings including the central irrigation opening at the same time, and the irrigation amount of the irrigation chamber 13 is reduced 1/2, as shown in fig. 13.
