Description

Technical Field

[0001] The invention relates to the field of corn planting drip irrigation devices, in particular to a drip irrigation type corn water and fertilizer application device. Background Art

[0002] Corn is a crop with a large planting area, wide distribution range, and diverse uses. It plays a very important role in agricultural production and the national economy. During the corn planting process, fertilization and irrigation of the corn roots are often completed through drip irrigation tapes, and the accuracy of the drip irrigation amount greatly affects the quality and yield of corn.

[0003] The existing corn water and fertilizer application device has the following problems that have not been well solved during use: 1. Due to the different water pressures at different positions of the water pipe, when drip irrigation is required for the planted corn, the farther the position is from the infusion pipe mouth, the lower the water pressure is, which affects the drip irrigation effect. The existing drip irrigation device needs to manually adjust the drip irrigation amount during use, which is inconvenient to use; 2. Since dead leaves are likely to exist on the surface of the soil where corn is planted, the existing drip irrigation device has difficulty in pushing away the dead leaves on the soil surface during drip irrigation, causing the drip irrigation liquid to flow out of the drip irrigation position along the surface of the dead leaves, making it difficult to perform drip irrigation operations effectively and accurately.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figures 1 to 10 The present invention provides a technical solution: a drip irrigation type corn water and fertilizer application device, comprising:

[0042] The water and fertilizer liquid storage cylinder 1 has a filter box 2 symmetrically fixedly connected to the bottom of the water and fertilizer liquid storage cylinder 1, and a drainage elbow 3 is fixedly connected to the bottom of the filter box 2. It should be noted that the two filter boxes 2 are fixedly connected to the bottom of the water and fertilizer liquid storage cylinder 1 via a Y-shaped liquid infusion tube. The Y-shaped liquid infusion tube is a prior art and will not be described in detail here.

[0043] Also includes:

[0044] There are four connecting sleeves 4, equidistantly positioned at the ends of the drainage elbow 3. A liquid infusion hose 5 is fixedly connected between two adjacent connecting sleeves 4. An adjustment mechanism 6 is flexibly connected between the upper portions of the four connecting sleeves 4 and the surfaces of the corresponding drainage elbows 3. This adjustment mechanism 6 is used to adjust the distance between the four connecting sleeves 4. A dripping mechanism 7, which cooperates with the adjustment mechanism 6 and is driven by the adjustment mechanism 6, is flexibly connected to the lower portion of the connecting sleeve 4. It should be noted that the liquid infusion hose 5 can deform when two adjacent connecting sleeves 4 move relative to each other, and the number of liquid infusion hoses 5 matches the number of connecting sleeves 4.

[0045] In this embodiment, Figures 1 to 10 As shown, the adjustment mechanism 6 includes two electric push rods 601, which are symmetrically fixed to the surface of the drain elbow 3. The movable ends of the electric push rods 601 are fixedly connected to the transmission plate 602. It should be noted that the electric push rods 601 are set as multi-stage electric telescopic rods.

[0046] The end of the infusion hose 5 away from the filter box 2 is fixedly connected to the positioning sleeve 603, the top of the positioning sleeve 603 is fixedly connected to the connecting bar 604, the top of the connecting bar 604 is fixedly connected to the bottom of the two transmission plates 602, and the tops of the three middle connecting sleeves 4 are fixedly connected to the transmission bar 605, and the top of the transmission bar 605 is slidably connected between the bottoms of two adjacent transmission plates 602. It should be noted that: a T-shaped transmission block is symmetrically fixedly connected to the top of the transmission bar 605, and a T-shaped transmission groove is provided at the bottom of the transmission plate 602, and the T-shaped transmission block is slidably connected to the inside of the corresponding T-shaped transmission groove; when the electric push rod 601 is extended, the electric push rod 601 moves synchronously with the transmission plate 602 and the connecting bar 604, so that the connecting bar 604 moves horizontally with the positioning sleeve 603. At this time, the positioning sleeve 603 pulls the three adjacent connecting sleeves 4 through the infusion hose 5 to move horizontally at the bottom of the two transmission plates 602, so that the three connecting sleeves 4 and the positioning sleeve 603 move horizontally and separate, and the corresponding infusion hose 5 is straightened during the separation process, and drip irrigation operation can be carried out at this time. Conversely, when the electric push rod 601 is retracted, the three connecting sleeves 4 and the positioning sleeve 603 move toward the water and fertilizer storage cylinder 1, and are retracted and stored, which is convenient for weeding and turning the soil for planting corn.

[0047] In this embodiment, Figures 1 to 10 As shown, a groove 606 is provided on the side wall of the upper portion of the connecting sleeve 4. A wire pulley rod 607 is rotatably connected to the interior of the groove 606. A pull rope 608 is fixedly connected to the surface of the wire pulley rod 607. One end of the pull rope 608 passes through the groove 606 and is fixedly connected to the side wall of the adjacent connecting sleeve 4. The pull rope 608 at a position away from the filter box 2 is fixedly connected to the side wall of the adjacent positioning sleeve 603. It should be noted that a coil spring is fixedly connected to the inner top surface of the groove 606. One end of the coil spring is fixedly connected to the surface of the corresponding wire pulley rod 607. When the four connecting sleeves 4 are separated and operated, the pull rope 608 is unwound on the surface of the wire pulley rod 607, causing the wire pulley rod 607 to rotate synchronously with the gear ring adjustment cylinder 610. Conversely, when the connecting sleeve 4 moves toward the water and fertilizer storage cylinder 1, the coil spring drives the shaft rod and the wire pulley rod 607 to reverse, causing the wire pulley rod 607 to reel the pull rope 608.

[0048] The interior of the connecting sleeve 4 is vertically provided with a vertical slot 609 that matches the groove 606. The interior of the vertical slot 609 is rotatably connected to the gear ring adjustment cylinder 610. The inner top surface of the vertical slot 609 is rotatably connected to the synchronous gear 611. The side walls of the synchronous gear 611 mesh with the side walls of the gear ring adjustment cylinder 610. The bottom of the spool rod 607 extends into the vertical slot 609 and is fixedly sleeved with a transmission gear 612. The side walls of the transmission gear 612 mesh with the side walls of the synchronous gear 611. It should be noted that the synchronous gear 611 is eccentrically arranged above the gear ring adjustment cylinder 610. By providing an annular tooth groove on the top of the gear ring adjustment cylinder 610, the synchronous gear 611 can mesh with the gear ring adjustment cylinder 610 for transmission. The synchronous gear 611 and the transmission gear 612 are both configured as small gears. After the spool rod 607 rotates several times with the transmission gear 612 meshing with the synchronous gear 611, it rotates 180 degrees with the gear ring adjustment cylinder 610.

[0049] The sidewalls of the gear ring adjustment cylinder 610 are symmetrically provided with arcuate grooves 613. Pull blocks 614 are symmetrically and vertically slidably connected to the inner walls of the vertical grooves 609. One end of the pull block 614 slides within the adjacent arcuate groove 613, and the other end of the pull block 614 is fixedly connected to a connecting rope 615. The outer wall of the connecting sleeve 4 is symmetrically and slidably connected to an arcuate slide bar 616. One end of the connecting rope 615 passes through the connecting sleeve 4 and is fixedly connected to the end of the adjacent arcuate slide bar 616. The lower end of the arcuate slide bar 616 is fixedly connected to the dripping mechanism 7 that cooperates with the connecting sleeve 4. It should be noted that when the gear ring adjustment cylinder 610 rotates 180 degrees, the arcuate groove 613 cooperates with the pull block 614, causing the pull block 614 to move downward within the vertical groove 609. At this time, the pull block 614 pulls the corresponding arcuate slide bar 616 via the connecting rope 615 to move along the outer wall of the connecting sleeve 4, and the arcuate slide bar 616 drives the dripping mechanism 7 to operate.

[0050] In this embodiment, Figures 1 to 10 As shown, sliders are symmetrically fixedly connected to both sides of the connecting sleeve 4, the two sliders are staggered, and the two arc-shaped sliding rods 616 are slidably connected to the inside of the two sliders respectively.

[0051] A reset ring is fixedly mounted on the surface of the curved slide 616, and a reset spring is movably mounted on the surface of the curved slide 616. The reset spring is disposed between the slide and the reset ring. It should be noted that when the reel rod 607 reverses and rewinds the pull rope 608, the gear ring adjustment cylinder 610 resets and rotates. The reset spring cooperates with the curved slide 616 and the connecting rope 615 to reset and move, allowing the pull block 614 to quickly rise and reset within the vertical slot 609.

[0052] In this embodiment, Figures 1 to 10As shown, the inner wall of the vertical slot 609 is symmetrically provided with inclined slots, and the two inclined slots correspond one to one with the two arc-shaped slide bars 616. The connecting rope 615 is movably inserted into the corresponding inclined slots, and the inner wall of the inclined slot is rotatably connected to a guide wheel that cooperates with the connecting rope 615. It should be noted that the guide wheel is provided to reduce frictional resistance during the movement of the connecting rope 615.

[0053] The inner wall of the vertical groove 609 is symmetrically vertically provided with movable grooves, and a vertical rod is fixedly connected between the top and bottom of the inner wall of the movable groove. The two pull blocks 614 are respectively slidably connected to the surfaces of the two vertical rods. The pull block 614 is fixedly connected to an adjustment pin on the side close to the gear ring adjustment cylinder 610, and the pull block 614 is slidably connected to the inside of the adjacent arc groove 613 through the adjustment pin.

[0054] A connecting bearing is fixedly connected between the bottom of the gear ring adjustment cylinder 610 and the inner bottom surface of the vertical groove 609.

[0055] In this embodiment, Figures 1 to 10 As shown, the dripping mechanism 7 includes a liquid guide tube 701, which is fixedly connected to the bottom of the connecting sleeve 4. Both ends of the liquid guide tube 701 are fixedly connected to a spring tube 702, and one end of the spring tube 702 is fixedly connected to a dripping head 703. The two dripping heads 703 are symmetrically and staggeredly arranged at the bottom of the connecting sleeve 4, and the upper part of the dripping head 703 is fixedly connected to the lower part of the adjustment mechanism 6. It should be noted that the spring tube 702 is arranged so that when the two dripping heads 703 move away from each other, the spring tube 702 can effectively extend to ensure that the liquid is stably transported into the interior of the dripping head 703; and the two curved sliding rods 616 on the surface of the connecting sleeve 4 correspond one-to-one to the two dripping heads 703. The bottom of the curved sliding rod 616 is fixedly connected to the upper part of the dripping head 703. When the curved sliding rod 616 slides along the surface of the connecting sleeve 4, it will move synchronously with the dripping head 703.

[0056] The drip head 703 has an H-shaped liquid storage tank 704 vertically extending inside, which cooperates with the spring tube 702. A baffle 705 is overlapped at the lower portion of the inner wall of the H-shaped liquid storage tank 704, and a compression spring 706 is movably connected between the bottom of the baffle 705 and the inner bottom surface of the H-shaped liquid storage tank 704. It should be noted that the compression spring 706 presses against the baffle 705 overlapped on the inner wall of the H-shaped vertical groove 609, thereby sealing the H-shaped vertical groove 609. The interior of the connecting sleeve 4 is provided with a chamber for liquid flow. The water and fertilizer liquid in the water and fertilizer storage cylinder 1 enters the drain elbow 3 from the filter box 2 and flows into the interior of the connecting sleeve 4. Then, it enters the interior of the spring tube 702 from the liquid guide tube 701 of the connecting sleeve 4, and finally is discharged from the drip head 703 at the lower end of the spring tube 702.

[0057] The lower part of the inner wall of the drip head 703 is provided with a conical groove 707 that matches the H-shaped liquid storage tank 704. The inner bottom surface of the conical groove 707 is overlapped with a sealing plate 708. The top plate of the sealing plate 708 and the bottom of the baffle 705 are hinged with a connecting rod 709. The lower part of the inner wall of the H-shaped liquid storage tank 704 is rotatably connected to a straight hinge ring 710, and two connecting rods 709 are hingedly installed at both ends of the straight hinge ring 710. It should be noted that: when the top of the baffle 705 is subjected to high water pressure, as the baffle 705 moves downward, in the process of coordinated deflection of the I-shaped hinge ring 710 and the connecting rod 709, the sealing plate 708 moves synchronously with the baffle 705 and translates toward the baffle 705. At this time, the gap between the top of the sealing plate 708 and the top surface of the conical groove 707 is smaller, so that the water flow at the position of the drip head 703 with high water pressure is reduced, and the flow rate is high; conversely, when the water pressure at the top of the baffle 705 is low, the distance the baffle 705 moves downward is reduced, so that the distance the sealing plate 708 rises is also reduced. At this time, the distance between the top of the sealing plate 708 and the top surface of the conical groove 707 is larger, so that the water flow at the position of the drip head 703 with low water pressure is increased, and the flow rate is low, thereby ensuring the uniformity of the total amount of liquid discharged by the drip heads 703 at different positions.

[0058] The upper portion of the dripping head 703 is vertically slidably connected to a clamping rod 711, the bottom of which is fixedly connected to the top of the baffle 705. A clamping groove 712 is symmetrically formed at the bottom of the connecting sleeve 4, and a clamping block 713 that cooperates with the clamping rod 711 is fixedly connected to the inner wall of the clamping groove 712. It should be noted that a vertical hole is formed at the upper portion of the dripping head 703, and the clamping rod 711 is vertically slidably connected to the interior of the vertical hole. A sealing ring is movably connected to the inner wall of the vertical hole and the surface of the clamping rod 711. The upper portion of the clamping rod 711 will not detach from the interior of the clamping groove 712 during the upward and downward sliding process, thereby avoiding affecting the coordination between the upper portion of the clamping rod 711 and the clamping block 713. The two clamping grooves 712 are symmetrically staggered and formed on the side wall of the lower portion of the connecting sleeve 4.

[0059] In this embodiment, Figures 1 to 10 As shown, both sides of the baffle 705 are slidably connected to a slide bar, and the two ends of the slide bar are fixedly connected to the inner wall of the H-shaped liquid storage tank 704. The compression spring 706 is movably connected to the surface of the slide bar. It should be noted that the slide bar is provided to prevent the baffle 705 from rotating inside the H-shaped vertical groove 609 and causing interference.

[0060] In this embodiment, Figures 1 to 10As shown, a limiting ball that cooperates with a sealing plate 708 is symmetrically fixedly connected to the upper portion of the inner wall of the conical groove 707. The sealing plate 708 is a conical plate that cooperates with the conical groove 707. The bottom of the drip head 703 is provided with a drip hole that cooperates with the sealing plate 708. It should be noted that: a guide rod is symmetrically fixedly connected to the bottom of the sealing plate 708, and a guide hole that cooperates with the guide rod is symmetrically opened on the inner bottom surface of the conical groove 707 to prevent the sealing plate 708 from rotating and affecting the use effect; the limiting ball is provided to prevent the sealing plate 708 from sealing the conical groove 707 after it rises to the limit position; the drip hole is provided so that when the sealing plate 708 moves down to the limit, it can seal the drip hole position, preventing mud from entering the interior of the drip head 703 when the device is not in use.

[0061] In this embodiment, Figures 1 to 10 As shown, the upper portion of the clamping rod 711 is fixedly connected to a latch pin, and the upper portion of the clamping rod 711 is slidably connected to the interior of the clamping slot 712. The upper portion of the clamping rod 711 is engaged with the latch block 713 via the latch pin. It should be noted that the trajectory of the latching slot 712 is the same as the movement trajectory of the arc-shaped slide bar 616. When the two arc-shaped slide bars 616 move the two drip heads 703 away from each other, the latch pin on the upper portion of the clamping rod 711 releases contact with the latch block 713, and the baffle 705 can now slide with the clamping rod 711 inside the drip head 703. When the two arc-shaped slide bars 616 move the two drip heads 703 relative to each other and stop using them, the clamping rod 711 moves along the trajectory of the clamping slot 712 with the latch pin to the position of the latch block 713. The latch block 713 restricts the movement of the clamping rod 711 inside the drip head 703. At this time, the baffle 705 seals the H-shaped vertical groove 609, thereby automatically stopping the drip irrigation operation.

[0062] In this embodiment, Figures 1 to 10 As shown, a liquid infusion pipe is fixedly connected to the front position of the upper part of the water and fertilizer liquid storage cylinder 1, and a water pressure regulator is fixedly connected to the right position of the upper part of the water and fertilizer liquid storage cylinder 1. It should be noted that the liquid infusion pipe and the water pressure regulator are both existing technologies and will not be described in detail here.

[0063] The bottom of the water and fertilizer 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 2

[0064] The use method and advantages of the present invention: The drip irrigation type corn water and fertilizer application device has the following working process:

[0065] Figures 1 to 10 As shown, when in use, first start the electric push rod 601 to move the transmission plate 602 in translation, so that the transmission plate 602 moves synchronously through the connecting strip 604 and the positioning sleeve 603. The positioning sleeve 603 pulls the three adjacent connecting sleeves 4 to move under the action of the infusion hose 5, so that the infusion hose 5 between two adjacent connecting sleeves 4 is straightened;

[0066] During the movement of the connecting sleeve 4, the connecting sleeve 4 moves synchronously with the pull rope 608 on the surface, so that the pull rope 608 engages the transmission gear 612 on the pulley rod 607 with the synchronous gear 611 during the unwinding process on the surface of the pulley rod 607. At this time, the synchronous gear ring engages and transmits with the top of the gear ring adjustment cylinder 610. Then, the arc groove 613 on the surface of the gear ring adjustment cylinder 610 cooperates with the pulling block 614 in the sliding process. The pulling block 614 and the connecting rope 615 cooperate to pull the arc sliding rod 616 along the arc surface track of the connecting sleeve 4. When the two arc sliding rods 616 at the bottom of the connecting sleeve 4 move in opposite directions, they move synchronously with the corresponding dripping heads 703, so that the two dripping heads 703 moving in opposite directions push away the dead leaves on the soil surface.

[0067] When the bottle is in the liquid phase, the bottle is in the liquid phase, and the bottle is in the liquid phase, so the bottle is in the liquid phase.

[0068] At the same time, during the dripping process, the dripping head 703 far away from the drainage bend 3 has a low hydraulic pressure and a low flow rate of the liquid, and the baffle 705 is subjected to a small pressure of water pressure, so that the baffle 705 moves down a small amount inside the H-shaped vertical groove 609. At this time, the sealing plate 708 that moves relative to the baffle 705 moves up a small amount, so that the gap between the sealing plate 708 and the top surface position of the corresponding conical groove 707 is large, so that the liquid inside the dripping head 703 far away from the drainage bend 3 has a low flow rate and a large discharge volume, ensuring that the dripping heads 703 at different positions can discharge liquid evenly.
