Description

Technical Field

[0001] The invention relates to the field of drip irrigation devices for corn planting, and in particular to an inter-row irrigation device for corn fields and a use method thereof. Background Art

[0002] In northern my country, rainfall is relatively little, which is not suitable for growing rice. Corn has good drought resistance and is the main crop grown by northern farmers. Corn can be used for food processing and feed processing and is an important food crop. Although corn has good drought resistance, watering is also required at an important stage of corn growth, and drip irrigation is one of the effective water-saving irrigation methods.

[0003] The existing patent (Announcement No.: CN115005061B) discloses a drip irrigation device for vegetable planting and a drip irrigation method thereof, including a water supply pipe, the end of which is connected to a water supply device through a solenoid valve, and a plurality of drip irrigation components are equidistantly connected to the surface of the water supply pipe. In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: 1. Due to the different water pressures at different positions of the water pipe, when drip irrigation is required for planted corn, the farther away from the infusion pipe mouth, the lower the water pressure, which affects the drip irrigation effect. The drip irrigation amount needs to be manually adjusted during use of the device, and the convenience of use is poor; 2. Due to the easy existence of dead leaves on the soil surface where corn is planted, the device is difficult to push away the dead leaves on the soil surface during drip irrigation, resulting in the drip irrigation liquid being diverted along the dead leaf surface out of the drip irrigation position, making it difficult to effectively and accurately perform drip irrigation operations.

[0021] The bottom of the liquid storage cylinder is symmetrically fixedly connected with a connecting column, and the bottom of the connecting column is fixedly connected to the top of the corresponding filter box.

[0022] A method for using a corn field inter-row irrigation device comprises the following steps:

[0023] S1. When in use, first start the electric push rod to move the U-shaped push block toward the axis of the liquid storage cylinder. At this time, the X-shaped connecting rod hinged to the U-shaped push block rotates on the surface of the shaft. Since the four X-shaped connecting rods are connected end to end, the four X-shaped connecting rods are deformed synchronously and move the corresponding connecting sleeves horizontally, so that the infusion hose between two adjacent connecting sleeves is straightened;

[0024] S2. During the movement of the connecting sleeve, the connecting sleeve moves synchronously with the pull rope on the surface, so that the pull rope rotates synchronously with the take-up wheel and the shaft rod during the unwinding process on the take-up wheel surface. At this time, the circular gear on the surface of the shaft rod meshes with the side walls of the two arc-shaped end face teeth for transmission, and the arc-shaped end face teeth drive the fixedly connected arc-shaped sliding rod to move along the arc-shaped surface track of the connecting sleeve. During the process of the two arc-shaped sliding rods at the bottom of the connecting sleeve moving in opposite directions, the corresponding drip heads move synchronously, so that the two drip heads moving in opposite directions push away the dead leaves on the soil surface;

[0025] S3, while the dripping head is turning over at the bottom of the connecting sleeve, the clamping rod at the upper part of the dripping head moves out from the clamping block position inside the connecting sleeve, and the baffle at the lower end of the clamping rod releases the limiting state, so that the liquid inside the liquid storage cylinder is transported from the filter box position to the drainage elbow, the connecting sleeve and the infusion hose, and the liquid enters the liquid guide tube, the spring tube and the dripping head from the connecting sleeve position in turn. Since the water pressure inside the dripping head near the drainage elbow position is high, the baffle is pressed down a long distance at this time, and in the transmission process of the rack and the gear rod, the baffle and the sealing plate move synchronously relative to each other. At this time, the gap between the sealing plate and the inner wall of the cone groove is small after the sealing plate rises, so that the liquid inside the dripping head near the drainage elbow position has a high flow rate and a small discharge volume;

[0026] S4. At the same time, during the dripping process, the dripping head far away from the discharge elbow has a low hydraulic pressure and a low flow rate of the liquid, while the water pressure on the baffle is small, so that the baffle moves down a small amount inside the H-shaped vertical groove. At this time, the sealing plate that moves relative to the baffle moves up a small amount, so that the gap between the sealing plate and the top surface of the corresponding conical groove is large, so that the liquid inside the dripping head far away from the discharge elbow has a low flow rate and a large discharge volume, ensuring that the dripping heads at different positions can discharge liquid evenly.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, by using the connecting sleeve, the adjusting mechanism, the dripping mechanism and other components in coordination, the dripping head close to the discharge elbow can reduce the discharge volume while discharging liquid at a high flow rate, while the dripping head far away from the discharge elbow can increase the discharge volume while discharging liquid at a low flow rate, thereby ensuring the uniformity of the total amount of liquid discharged by the dripping heads at different positions.

[0029] In the present invention, by using the connecting sleeve, the adjusting mechanism and the dripping head together, when the adjusting mechanism is running, the two dripping heads at the bottom of the connecting sleeve move in opposite directions, and the two dripping heads push away the dead leaves on the soil surface to prevent the dead leaves from diverting the liquid out of the drip irrigation position, thereby ensuring accurate drip irrigation operations.

[0030] In the present invention, through the coordinated use of the adjusting mechanism, the clamping rod, the clamping slot and other components, when the adjusting mechanism moves the two dripping heads relative to each other, the clamping rod and the clamping block cooperate to seal the inside of the dripping head, and the drip irrigation operation is automatically stopped; conversely, when the two dripping heads move away from each other, the clamping rod and the clamping block are released from the clamping state, the inside of the dripping head is released from the sealed state, and the drip irrigation operation is automatically performed, thereby improving the convenience of use.

DETAILED DESCRIPTION

[0039] The following will be combined with the 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 described embodiments 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 7 The present invention provides a technical solution: a corn field inter-row irrigation device, comprising a liquid storage cylinder 1, a Y-shaped liquid infusion tube 2 is fixedly connected to the bottom of the liquid storage cylinder 1, a filter box 3 is symmetrically fixedly connected to the bottom of the Y-shaped liquid infusion tube 2, the top of the filter box 3 is fixedly connected to the bottom of the liquid storage cylinder 1, a drainage elbow 4 is fixedly connected to the bottom of the filter box 3, four connecting sleeves 5 are equidistantly arranged at one end of the drainage elbow 4 away from the filter box 3, and a liquid infusion hose 6 is fixedly connected between two adjacent connecting sleeves 5. It should be noted that when two adjacent connecting sleeves 5 move relative to each other, the liquid infusion hose 6 can be deformed, and the number of the liquid infusion hose 6 is consistent with the number of the connecting sleeves 5.

[0041] An adjusting mechanism 7 is movably connected between the upper parts of the four connecting sleeves 5 and the bottoms of the corresponding filter boxes 3 , and a dripping mechanism 8 matched with the adjusting mechanism 7 is movably connected to the lower part of the connecting sleeve 5 .

[0042] The adjustment mechanism 7 includes an electric push rod 701, which is fixedly connected to the bottom of the filter box 3, and the movable end of the electric push rod 701 is fixedly connected to a U-shaped push block 702. It should be noted that the movable end of the electric push rod 701 cannot rotate, but can only move in a translational manner to prevent the U-shaped push block 702 from rotating and affecting the use effect.

[0043] The tops of the four connecting sleeves 5 are all rotatably connected to the shaft rod 703, and the upper part of the shaft rod 703 is rotatably connected to the X-shaped connecting rod 704. The four X-shaped connecting rods 704 are hingedly installed end to end. The X-shaped connecting rod 704 close to the U-shaped push block 702 is symmetrically provided with waist-shaped grooves 705 on the left side, and the two ends of the U-shaped push block 702 are respectively slidably connected to the inside of the two waist-shaped grooves 705. The end of the infusion hose 6 away from the discharge elbow 4 is fixedly connected to the positioning sleeve 706, and the top of the positioning sleeve 706 is rotatably connected to the positioning rod 707. The upper part of the positioning rod 707 is rotatably connected to the V-shaped connecting rod 708, and the two ends of the V-shaped connecting rod 708 are hinged to the ends of the adjacent X-shaped connecting rods 704. It should be noted that: both ends of the U-shaped push block 702 are fixedly connected with sliding pins, and the sliding pins are slidably connected to the inside of the corresponding waist-shaped groove 705. When the U-shaped push block 702 moves toward the axial direction of the liquid storage cylinder 1, during the sliding cooperation between the waist-shaped groove 705 and the U-shaped push block 702, the left and right ends of the X-shaped connecting rod 704 move away from each other, and the four X-shaped connecting rods 704 move synchronously, so that the four connecting sleeves 5 move synchronously and straighten the infusion hose 6. At this time, drip irrigation can be carried out. Conversely, the left and right ends of the X-shaped connecting rod 704 move relatively, so that the four connecting sleeves 5 move synchronously toward the axial direction of the liquid storage cylinder 1, and shrink and store them, which is convenient for weeding and turning the soil for planting corn.

[0044] A groove 709 is provided on the side wall of the upper part of the connecting sleeve 5, and a take-up wheel 710 is rotatably connected inside the groove 709. The bottom of the shaft rod 703 extends into the groove 709 and is fixedly connected to the top of the take-up wheel 710. A pull rope 711 is fixedly connected to the surface of the take-up wheel 710. One end of the pull rope 711 passes through the groove 709 and is fixedly connected to the side wall of the adjacent connecting sleeve 5. The pull rope 711 away from the position of the drainage bend 4 is fixedly connected to the side wall of the adjacent positioning sleeve 706. A coil spring 712 is provided inside the groove 709. One end of the coil spring 712 is fixedly connected to the surface of the corresponding shaft rod 703, and the other end of the coil spring 712 is fixedly connected to the inner wall of the groove 709. It should be noted that: when the four connecting sleeves 5 are separated and operated at equal intervals, the pull rope 711 is unwound on the surface of the take-up wheel 710, so that the take-up wheel 710 rotates synchronously with the shaft 703. Conversely, when the four connecting sleeves 5 move synchronously toward the liquid storage cylinder 1, the winding spring 712 reverses the shaft 703 and the take-up wheel 710, so that the take-up wheel 710 reels the pull rope 711.

[0045] The upper part of the shaft 703 is fixedly sleeved with a circular gear 713, which is arranged below the X-shaped connecting rod 704. Slide blocks 714 are symmetrically fixedly connected to the two sides of the connecting sleeve 5. The two slide blocks 714 are staggered. The middle part of the slide block 714 is slidably connected with an arc-shaped slide bar 715. One side of the arc-shaped slide bar 715 is fixedly connected with an arc-shaped end face tooth 716. The side wall of the arc-shaped end face tooth 716 meshes with the side wall of the circular gear 713. The lower end of the arc-shaped slide bar 715 is fixedly connected with a drip mechanism 8 that matches the connecting sleeve 5. It should be noted that when the shaft 703 rotates with the circular gear 713 to mesh with the two arc-shaped end face teeth 716, the two staggered arc-shaped end face teeth 716 move the arc-shaped slide bar 715 drip mechanism 8 away from each other at the lower part of the connecting sleeve 5 and are in an inclined state to perform drip irrigation.

[0046] In this embodiment, Figures 1 to 7 As shown, the upper part of the shaft 703 is symmetrically fixedly connected with a retaining ring, and the X-shaped connecting rod 704 is rotatably connected between the two retaining rings. It should be noted that the rotatable connection setting ensures that the shaft 703 will not rotate synchronously with the X-shaped connecting rod 704 during the rotation process.

[0047] In this embodiment, Figures 1 to 7 As shown, an arc-shaped end face tooth 716 is provided with an arc-shaped positioning groove on one side close to the surface of the connecting sleeve 5, a ball head positioning pin matched with the arc-shaped positioning groove is fixedly connected to the surface of the connecting sleeve 5, and a U-shaped positioning block is slidably connected to the surface of the arc-shaped end face tooth 716, and the U-shaped positioning block is fixedly connected to the surface of the connecting sleeve 5. It should be noted that the U-shaped positioning block, the arc-shaped positioning groove and the ball head positioning pin are provided to ensure the stability of the arc-shaped end face tooth 716 during the sliding process of the side wall of the connecting sleeve 5.

[0048] Two arc-shaped end face teeth 716 are symmetrically arranged on both sides of the circular gear 713 .

[0049] In this embodiment, Figures 1 to 7 As shown, the dripping mechanism 8 includes a liquid guide tube 801, which is fixedly connected to the bottom of the connecting sleeve 5, and the two ends of the liquid guide tube 801 are fixedly connected to a spring tube 802, and one end of the spring tube 802 is fixedly connected to a dripping head 803, and the two dripping heads 803 are symmetrically and staggeredly arranged at the bottom of the connecting sleeve 5, and the upper part of the dripping head 803 is fixedly connected to the lower part of the adjusting mechanism 7. It should be noted that: the spring tube 802 is arranged, and when the two dripping heads 803 move in opposite directions, the spring tube 802 can be effectively extended to ensure that the liquid is stably transported into the inside of the dripping head 803; and the two arc-shaped slide bars 715 on the surface of the connecting sleeve 5 correspond to the two dripping heads 803 one by one, and the bottom of the arc-shaped slide bar 715 is fixedly connected to the upper part of the dripping head 803, and when the arc-shaped slide bar 715 slides along the surface of the connecting sleeve 5, it will move synchronously with the dripping head 803.

[0050] The drip head 803 is vertically provided with an H-shaped vertical groove 804 that matches the spring tube 802. A baffle 805 is overlapped at the lower part of the inner wall of the H-shaped vertical groove 804. A compression spring 806 is movably connected between the bottom of the baffle 805 and the inner bottom surface of the H-shaped vertical groove 804. It should be noted that the compression spring 806 presses the baffle 805 overlapped on the inner wall of the H-shaped vertical groove 804 to seal the H-shaped vertical groove 804.

[0051] The lower part of the inner wall of the drip head 803 is provided with a conical groove 807 that matches the H-shaped vertical groove 804, and the inner bottom surface of the conical groove 807 is overlapped with a sealing plate 808. The top plate of the sealing plate 808 and the bottom of the baffle 805 are fixedly connected with a rack 809. The lower part of the inner wall of the H-shaped vertical groove 804 is rotatably connected with a gear rod 810, and the opposite sides of the two racks 809 are respectively meshed with the two sides of the gear rod 810. It should be noted that: when the top of the baffle 805 is subjected to high water pressure, during the meshing transmission process of the two racks 809 and the gear rod 810, the sealing plate 808 moves synchronously with the baffle 805 and translates toward the baffle 805. At this time, the gap between the top of the sealing plate 808 and the top surface of the cone groove 807 is smaller, so that the water flow rate at the position of the drip head 803 with high water pressure is reduced, while the flow rate is high; conversely, when the water pressure at the top of the baffle 805 is low, the distance that the baffle 805 moves downward is reduced, so that the distance that the sealing plate 808 rises is also reduced. At this time, the distance between the top of the sealing plate 808 and the top surface of the cone groove 807 is larger, so that the water flow rate at the position of the drip head 803 with low water pressure is increased, while the flow rate is low, thereby ensuring the uniformity of the total amount of liquid discharged by the drip heads 803 at different positions.

[0052] The upper part of the drip head 803 is vertically slidably connected with a clamping rod 811, the bottom of the clamping rod 811 is fixedly connected to the top of the baffle 805, and the bottom of the connecting sleeve 5 is symmetrically provided with a clamping groove 812, and the inner wall of the clamping groove 812 is fixedly connected with a clamping block 813 that matches the clamping rod 811. It should be noted that: a vertical hole is provided at the upper part of the drip head 803, and the clamping rod 811 is vertically slidably connected inside the vertical hole, and a sealing ring is movably connected between the inner wall of the vertical hole and the surface of the clamping rod 811; and the upper part of the clamping rod 811 will not be separated from the inside of the clamping groove 812 during the up and down sliding process, so as to avoid affecting the coordinated use of the upper part of the clamping rod 811 and the clamping block 813, and the two clamping grooves 812 are symmetrically staggered and provided on the side wall of the lower part of the connecting sleeve 5.

[0053] In this embodiment, Figures 1 to 7 As shown, both sides of the baffle 805 are slidably connected with slide bars, the two ends of the slide bars are fixedly connected to the inner wall of the H-shaped vertical groove 804, and the compression spring 806 is movably sleeved on the surface of the slide bars. It should be noted that the slide bars are set to prevent the baffle 805 from rotating inside the H-shaped vertical groove 804 and causing interference.

[0054] In this embodiment, Figures 1 to 7As shown, the upper part of the inner wall of the conical groove 807 is symmetrically fixedly connected with a limiting ball matched with the sealing plate 808, the sealing plate 808 is set as a conical plate matched with the conical groove 807, and the bottom of the drip head 803 is provided with a drip hole matched with the sealing plate 808. It should be noted that: the bottom of the sealing plate 808 is symmetrically fixedly connected with a guide rod, and the inner bottom surface of the conical groove 807 is symmetrically provided with a guide hole matched with the guide rod to prevent the sealing plate 808 from rotating and affecting the use effect; the limiting ball is set to prevent the sealing plate 808 from sealing the conical groove 807 after rising to the limit position; the drip hole is set, when the sealing plate 808 moves down to the limit, the sealing plate 808 can seal the drip hole position to prevent the inside of the drip head 803 from entering the soil when the device is not in use.

[0055] In this embodiment, Figures 1 to 7 As shown, the upper part of the clamping rod 811 is fixedly connected with a clamping pin, and the upper part of the clamping rod 811 is slidably connected to the inside of the clamping slot 812, and the upper part of the clamping rod 811 is clamped with the clamping block 813 through the clamping pin. It should be noted that: the track of the clamping slot 812 is the same as the moving track of the arc-shaped slide bar 715. When the two arc-shaped slide bars 715 move the two drip heads 803 in opposite directions, the clamping pin on the upper part of the clamping rod 811 is released from contact with the clamping block 813, and the baffle 805 can slide inside the drip head 803 with the clamping rod 811; when the two arc-shaped slide bars 715 move the two drip heads 803 relative to each other and stop using, the clamping rod 811 moves along the track of the clamping slot 812 with the clamping pin to the position of the clamping block 813, and the clamping block 813 restricts the movement of the clamping rod 811 inside the drip head 803, and the baffle 805 seals the position of the H-shaped vertical groove 804, thereby automatically stopping the drip irrigation operation.

[0056] In this embodiment, Figures 1 to 7 As shown, a liquid infusion tube is fixedly connected to the front position of the upper part of the liquid storage cylinder 1, and a water pressure regulator is fixedly connected to the right position of the upper part of the liquid storage cylinder 1. It should be noted that the liquid infusion tube and the water pressure regulator are both prior art and will not be described in detail here.

[0057] The bottom of the liquid storage cylinder 1 is symmetrically fixedly connected with a connecting column, and the bottom of the connecting column is fixedly connected to the top of the corresponding filter box 3.

[0058] In this embodiment, Figures 1 to 7 As shown, a method for using a corn field inter-row irrigation device comprises the following steps:

[0059] S1. When in use, first start the electric push rod 701 to move the U-shaped push block 702 toward the axial direction of the liquid storage cylinder 1. At this time, the X-shaped connecting rod 704 hinged to the U-shaped push block 702 rotates on the surface of the shaft 703. Since the four X-shaped connecting rods 704 are connected end to end, the four X-shaped connecting rods 704 are deformed synchronously and move the corresponding connecting sleeves 5 horizontally, so that the infusion hose 6 between two adjacent connecting sleeves 5 is straightened;

[0060] S2. During the movement of the connecting sleeve 5, the connecting sleeve 5 moves synchronously with the pull rope 711 on the surface, so that the pull rope 711 rotates synchronously with the take-up wheel 710 and the shaft 703 during the unwinding process on the surface of the take-up wheel 710. At this time, the circular gear 713 on the surface of the shaft 703 meshes with the side walls of the two arc-shaped end face teeth 716 for transmission, and the arc-shaped end face teeth 716 drive the fixedly connected arc-shaped slide bar 715 to move along the arc-shaped surface track of the connecting sleeve 5. During the process of the two arc-shaped slide bars 715 at the bottom of the connecting sleeve 5 moving in opposite directions, the corresponding drip heads 803 move synchronously, so that the two drip heads 803 moving in opposite directions push away the dead leaves on the soil surface;

[0061] S3, while the dripping head 803 is turning over at the bottom of the connecting sleeve 5, the clamping rod 811 at the upper part of the dripping head 803 moves out from the position of the clamping block 813 inside the connecting sleeve 5, and the baffle 805 at the lower end of the clamping rod 811 releases the limiting state, so that the liquid inside the liquid storage cylinder 1 is transported from the position of the filter box 3 to the drainage elbow 4, the connecting sleeve 5 and the infusion hose 6, and the liquid enters the guide tube 801, the spring tube 802 and the dripping head 803 from the position of the connecting sleeve 5 in turn. Since the water pressure inside the dripping head 803 near the drainage elbow 4 is large, the baffle 805 is pressed down by a large distance at this time, and in the transmission process of the rack 809 and the gear rod 810, the baffle 805 and the sealing plate 808 move synchronously relative to each other. At this time, the gap between the sealing plate 808 and the inner wall of the cone groove 807 after it rises is small, so that the liquid inside the dripping head 803 near the drainage elbow 4 has a high flow rate and a small discharge volume;

[0062] S4. At the same time, during the dripping process, the drip head 803 far away from the discharge bend 4 has a low hydraulic pressure and a low flow rate of the liquid, while the water pressure on the baffle 805 is small, so that the baffle 805 moves down a small amount inside the H-shaped vertical groove 804. At this time, the sealing plate 808 that moves relative to the baffle 805 moves up a small amount, so that the gap between the sealing plate 808 and the top surface of the corresponding conical groove 807 is large, so that the liquid inside the drip head 803 far away from the discharge bend 4 has a low flow rate and a large discharge volume, ensuring that the drip heads 803 at different positions can discharge liquid evenly.

Technical personnel in this industry should understand that the present invention is not limited to the above embodiments.

9. A method for using a corn field inter-row irrigation device, characterized in that: Using the inter-row irrigation device for corn fields as claimed in claim 8 comprises the following steps: S1. When in use, first start the electric push rod (701) to move the U-shaped push block (702) toward the axial direction of the liquid storage cylinder (1). At this time, the X-shaped connecting rod (704) hinged to the U-shaped push block (702) rotates on the surface of the shaft (703). Since the four X-shaped connecting rods (704) are connected end to end, the four X-shaped connecting rods (704) are deformed synchronously and move the corresponding connecting sleeves (5) horizontally, so that the infusion hose (6) between two adjacent connecting sleeves (5) is straightened; S2. During the movement of the connecting sleeve (5), the connecting sleeve (5) moves synchronously with the pull rope (711) on the surface, so that the pull rope (711) rotates synchronously with the take-up wheel (710) and the shaft (703) during the unwinding process on the take-up wheel (710). At this time, the circular gear (713) on the surface of the shaft (703) meshes with the side walls of the two arc-shaped end face teeth (716) for transmission, and the arc-shaped end face teeth (716) drive the fixedly connected arc-shaped slide bar (715) to move along the arc-shaped surface track of the connecting sleeve (5). During the process of the two arc-shaped slide bars (715) at the bottom of the connecting sleeve (5) moving in opposite directions, the corresponding drip heads (803) move synchronously, so that the two drip heads (803) moving in opposite directions push away the dead leaves on the soil surface; S3. At the same time, when the dripping head (803) is turned over at the bottom of the connecting sleeve (5), the clamping rod (811) at the upper part of the dripping head (803) moves out from the position of the clamping block (813) inside the connecting sleeve (5). At this time, the baffle (805) at the lower end of the clamping rod (811) is released from the limiting state, so that the liquid inside the liquid storage cylinder (1) is transported from the position of the filter box (3) to the drainage elbow (4), the connecting sleeve (5) and the infusion hose (6). The liquid enters the liquid guide tube (801) and the spring tube (802) from the position of the connecting sleeve (5) in turn. and inside the drip head (803). Since the water pressure inside the drip head (803) near the discharge elbow (4) is high, the baffle (805) is pressed down by a large distance. In the transmission process of the rack (809) and the gear rod (810), the baffle (805) and the sealing plate (808) move relative to each other synchronously. At this time, after the sealing plate (808) rises, the gap between the sealing plate (808) and the inner wall of the conical groove (807) is small, so that the liquid inside the drip head (803) near the discharge elbow (4) has a high flow rate and a small discharge volume. S4. At the same time, during the dripping process, the dripping head (803) far away from the discharge elbow (4) has a low hydraulic pressure and a low flow rate of the liquid, and the water pressure on the baffle (805) is small, so that the baffle (805) moves downward a small amount inside the H-shaped vertical groove (804). At this time, the sealing plate (808) that moves relative to the baffle (805) moves upward a small amount, so that the gap between the sealing plate (808) and the top surface of the corresponding conical groove (807) is large, so that the liquid inside the dripping head (803) far away from the discharge elbow (4) has a low flow rate and a large discharge volume, ensuring that the dripping heads (803) at different positions can discharge liquid evenly.
