Description

Technical Field

[0001] The present invention relates to the technical field of irrigation and fertilization equipment, and particularly to an integrated irrigation and fertilization equipment for citrus trees that combines water and fertilizer. Background Art

[0002] As one of the important fruits widely cultivated in the world, citrus has relatively high requirements for water and nutrients during its growth. To ensure the healthy growth, high and stable yields of citrus trees, effective irrigation and fertilization management are needed to ensure sufficient water and nutrient supply, which is crucial for the growth of citrus trees, the quality and yield of fruits.

[0003] The current integrated irrigation and fertilization technology for citrus trees mainly includes two methods: sprinkler irrigation and drip irrigation. The sprinkler irrigation system installs pipes above citrus trees through brackets. These pipes are equipped with multiple sprinkler heads, enabling irrigation from top to bottom. At the same time, a drip irrigation system is laid on the ground around the citrus tree trunks, consisting of multiple pipes distributed on both sides of the citrus trees. Each pipe is provided with small holes or sprinkler heads, allowing water and fertilizer to directly drip into the roots of citrus trees to achieve precise drip irrigation.

[0004] Although the existing integrated irrigation and fertilization equipment that combines sprinkler irrigation and drip irrigation can achieve drip irrigation and irrigation for citrus trees, there is a significant problem with the existing integrated irrigation and fertilization equipment that combines sprinkler irrigation and drip irrigation: the height and coverage area of the sprinkler irrigation system are fixed. This leads to an inability to adapt to changes as the citrus trees grow, with the tree height and the range of branches and leaves increasing. As a result, uneven sprinkler irrigation occurs. For growing citrus trees, the fixed sprinkler irrigation range may not fully cover the increasing tree crown; while for young citrus trees, the excessive sprinkler irrigation area may cause waste of resources. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated irrigation and fertilization equipment for citrus trees that can dynamically adjust the sprinkler irrigation height and area according to different growth stages of citrus trees to solve the above problems.

[0006] The present invention achieves the above object through the following technical solutions: A citrus integrated water and fertilizer irrigation and fertilization device, including a support frame. A drip irrigation pipe is provided between the lower parts of the left and right support frames. Dripper heads are arranged at intervals on the drip irrigation pipe. Lifting blocks are slidably arranged on both support frames. A conveying pipeline is arranged between the two lifting blocks. The conveying pipeline is communicated with the drip irrigation pipe. A solenoid valve I is installed on one side of the drip irrigation pipe close to the conveying pipeline. Vertical pipes are connected to the conveying pipeline at intervals. A sprinkler irrigation mechanism is arranged on the vertical pipes. The sprinkler irrigation mechanism includes a conical nozzle connected to the bottom end of the vertical pipe. A plurality of liquid spraying holes are circumferentially spaced on the circumferential side wall of the conical nozzle. A ring frame I is slidably arranged outside the vertical pipe. A plurality of sliding grooves are circumferentially spaced on the upper part of the ring frame I. Sliders are arranged in the sliding grooves. The bottom of the slider is connected with a blocking plate for blocking the liquid spraying holes. The growth of citrus trees pushes the ring frame I upward, so that the slider pulls the blocking plate upward to expose the liquid spraying holes, thereby increasing the sprinkler irrigation area. A driving mechanism for driving the lifting block to lift is arranged on the support frame.

[0007] Preferably, a plurality of guide grooves are circumferentially spaced on the circumferential side wall of the conical nozzle for guiding the lifting of the blocking plate. Semi-circular grooves are opened on both the left and right sides in the guide grooves. Semi-circular rods matching the semi-circular grooves are connected to both the left and right sides of the blocking plate.

[0008] Preferably, a ring frame II is slidably arranged at the lower part of the ring frame I. The bottom of the ring frame II is lower than the bottom of the ring frame I. A screw rod is connected to the ring frame II. A nut is threadedly connected to the screw rod. The nut is rotatably connected to the ring frame II. The growth of citrus trees pushes the ring frame II upward, so that the screw rod pulls the ring frame I upward through the nut.

[0009] Preferably, the conveying pipeline includes a hard short pipe, a short flexible pipe, a three-way pipe, a four-way pipe, a long flexible pipe, a solenoid valve II and a valve. The left and right hard short pipes are respectively connected to the two lifting blocks. Short flexible pipes are arranged at intervals between the two hard short pipes. The leftmost and rightmost short flexible pipes are respectively connected to the left and right hard short pipes. Adjacent short flexible pipes are communicated through a three-way pipe. The vertical pipe is connected to the three-way pipe. A four-way pipe is connected to the water inlet end of the left hard short pipe. The four-way pipe is communicated with the drip irrigation pipe through a long flexible pipe. A solenoid valve II is installed on the left hard short pipe. A valve is installed at the rear side of the four-way pipe.

[0010] Preferably, the driving mechanism includes an inner rhombic rod rotatably connected to the lower part of the support frame. A wire winding wheel is connected to the outside of the inner rhombic rod. A fixed pulley is arranged at the upper part of the support frame. A pulling rope is wound on the wire winding wheel. The pulling rope bypasses the fixed pulley and is connected to the lifting block. An outer rhombic crank is inserted into the inner rhombic rod. A locking component for locking the outer rhombic crank is arranged at the lower part of the support frame.

[0011] Preferably, the locking assembly includes a ratchet wheel connected to the lower part of the support frame. The axis of the ratchet wheel is flush with the axis of the inner diamond rod. A connecting block located outside the inner diamond rod is connected to the outer diamond rocker. A swivel ring is rotatably connected to the connecting block. A pawl is connected to the outer wall of the swivel ring. Both the swivel ring and the pawl are located at an eccentric position within the ratchet wheel. A notch is formed in the connecting block for the pawl to rotate and disengage from the ratchet wheel. A scroll spring is connected between the swivel ring and the connecting block.

[0012] Preferably, a positioning block is connected inside the inner diamond rod, and a slotted cross recess matching the positioning block is formed in the outer diamond rocker.

[0013] Preferably, a telescopic protective sleeve is sleeved on the short hose. Elastic bands are connected to both the left and right ends of the telescopic protective sleeve. Retaining rings are connected to one side of the outer wall of the rigid short pipe close to the short hose and to both the left and right sides of the outer wall of the three-way pipe. The retaining rings are used to block the elastic bands.

[0014] The present invention has the following advantages compared with the prior art: 1. The driving mechanism can drive the lifting block to drive the conveying pipeline to lift, so as to adjust the heights of the conical nozzle and the first ring frame, so that the conical nozzle can always be kept above the citrus tree, and thus the irrigation height can be dynamically adjusted according to different growth stages of the citrus tree; and the first ring frame can always be kept in contact with the crown of the citrus tree. When the citrus tree grows, it will push the first ring frame to move upward. The upward movement of the first ring frame pulls the plug plate upward through the slider to gradually expose the liquid spraying holes. As the liquid spraying holes of the conical nozzle are gradually exposed from bottom to top, the irrigation area is gradually increased, so that the irrigation area can be dynamically adjusted according to different growth stages of the citrus tree. By dynamically adjusting the irrigation height and area according to different growth stages of the citrus tree, the utilization rate of water resources can be improved while ensuring that each citrus tree can obtain appropriate water supply, improving the uniformity of irrigation, ensuring that each citrus tree can obtain appropriate irrigation, and enhancing the overall irrigation effect.

[0015] 2. Rotating the nut drives the screw rod to drive the second ring frame to lift, so as to adjust the height of the second ring frame, so that the second ring frame contacts the citrus tree, so as to adapt to citrus trees with different growth speeds and heights, further ensure that each citrus tree can obtain appropriate irrigation, and further enhance the overall irrigation effect.

Specific embodiments

[0029] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] See Figures 1 - 5, A citrus integrated water and fertilizer irrigation and fertilization device, including a support frame 1. A drip irrigation pipe 2 is provided between the lower parts of the left and right support frames 1. Dripper heads 21 are arranged at intervals on the drip irrigation pipe 2. Lifting blocks 3 are slidably arranged on both support frames 1. A conveying pipeline 4 is arranged between the two lifting blocks 3. The conveying pipeline 4 includes a hard short pipe 41, a short flexible pipe 42, a three-way pipe 43, a four-way pipe 44, a long flexible pipe 45, a solenoid valve two 46 and a valve 47. The left and right hard short pipes 41 are respectively connected to the two lifting blocks 3. Short flexible pipes 42 are arranged at intervals between the two hard short pipes 41. The leftmost and rightmost short flexible pipes 42 are respectively connected to the left and right hard short pipes 41. Adjacent two short flexible pipes 42 are communicated through a three-way pipe 43. The right hard short pipe 41 is in a sealed state and does not output liquid. The water inlet end of the left hard short pipe 41 is connected with a four-way pipe 44. The four-way pipe 44 is communicated with the drip irrigation pipe 2 through a long flexible pipe 45. A solenoid valve two 46 is installed on the left hard short pipe 41. A valve 47 is installed at the rear side of the four-way pipe 44. A solenoid valve one 22 is installed on the side of the drip irrigation pipe 2 close to the long flexible pipe 45. A vertical pipe 5 is connected to each three-way pipe 43. A sprinkler irrigation mechanism is arranged on the vertical pipe 5. The sprinkler irrigation mechanism includes a conical nozzle 60 connected to the bottom end of the vertical pipe 5. Six groups of liquid spraying holes 61 are circumferentially spaced on the circumferential side wall of the conical nozzle 60. The number of each group of liquid spraying holes 61 is nine. The nine liquid spraying holes 61 in each group are axially distributed along the conical nozzle 60. A ring frame one 62 that can be lifted and lowered is slidably arranged outside the vertical pipe 5. The ring frame one 62 includes a sliding sleeve 621, a small round plate 622, a large round plate 623, a vertical rod 624 and a circular ring plate 625. The sliding sleeve 621 is slidably sleeved outside the vertical pipe 5. The sliding sleeve 621 is connected with a small round plate 622 and a large round plate 623. The large round plate 623 is located below the small round plate 622 and above the conical nozzle 60. Two vertical rods 624 are circumferentially spaced and connected to the bottom of the small round plate 622. The bottom ends of the two vertical rods 624 pass through the large round plate 623 and are connected with a circular ring plate 625. Six chutes 63 are circumferentially spaced on the large round plate 623 of the ring frame one 62. Sliders 64 are slidably arranged in the chutes 63. A blocking plate 65 for blocking the liquid spraying holes 61 is connected to the bottom of the slider 64. The growth of the citrus tree 10 pushes the ring frame one 62 to move upward, so that the slider 64 pulls the blocking plate 65 to move upward to expose the liquid spraying holes 61, thereby increasing the sprinkler irrigation area. Six guide grooves 66 are circumferentially spaced on the circumferential side wall of the conical nozzle 60 for guiding the lifting of the blocking plate 65. Semi-circular grooves 67 are opened on both the left and right sides in the guide grooves 66. Semi-circular rods 68 that match the semi-circular grooves 67 are connected to both the left and right sides of the blocking plate 65. Through the cooperation of the guide grooves 66, the semi-circular grooves 67 and the semi-circular rods 68, the lifting of the blocking plate 65 can be effectively guided, ensuring that the blocking plate 65 always closely adheres to the circumferential side wall of the conical nozzle 60, preventing the blocking plate 65 from separating from the conical nozzle 60 when moving upward, so as to ensure the effective blocking of the unexposed liquid spraying holes 61. A driving mechanism for driving the lifting blocks 3 to lift and lower is arranged on the support frame 1.

[0031] Place this device at the planting row of citrus tree 10. Then, the conical nozzle 60 is located above the citrus tree 10, and the first ring support 62 is located on the upper side of the citrus tree 10 and contacts the canopy of the citrus tree 10. Place this device at the planting row of each row of citrus trees 10. Connect pipes to the four-way pipe 44 of the conveying pipe 4, and the conveying pipes 4 of two adjacent devices before and after can be connected. Connect the infusion device to the four-way pipe 44 of the device at the planting row of the citrus trees 10 in the frontmost row. Then, the liquid is conveyed into the four-way pipe 44 through the infusion device. Close the valve 47 of the device at the planting row of the citrus trees 10 in the rearmost row to avoid waste of liquid overflowing from the rear end of the four-way pipe 44 of the device at the planting row of the citrus trees 10 in the rearmost row.

[0032] When it is necessary to directly drip the water and fertilizer into the root of the citrus tree 10 to achieve precise drip irrigation, control the second solenoid valve 46 to close to prevent the water and fertilizer from entering the left hard short pipe 41 and spraying out through the conical nozzle 60. At the same time, control the first solenoid valve 22 to open. The water and fertilizer enter the drip irrigation pipe 2 through the long hose 45 and finally flow out from the drip head 21 and directly drip into the root of the citrus tree 10 to achieve precise drip irrigation. When it is necessary to spray or apply pesticides to the citrus tree 10, control the first solenoid valve 22 to close to prevent water or liquid medicine from entering the drip irrigation pipe 2. At the same time, control the second solenoid valve 46 to open. Water or liquid medicine enters the left hard short pipe 41. Then, the water or liquid medicine sequentially flows through the short hose 42, the three-way pipe 43 and the vertical pipe 5, and then enters the conical nozzle 60 and finally sprays out from the conical nozzle 60 to achieve spraying or applying pesticides to the citrus tree 10.

[0033] Initially, the liquid spraying holes 61 of the conical nozzle 60 are blocked by the plug plate 65. Water sprays out from the liquid spraying port at the bottom of the conical nozzle 60, and the spraying area is small, which is suitable for young citrus trees 10 and reduces waste of resources. When the citrus tree 10 grows, it will push the first ring support 62 to move upward. The upward movement of the first ring support 62 pulls the plug plate 65 to move upward through the slider 64, gradually exposing the liquid spraying holes 61. Then, water can spray out from the liquid spraying holes 61 to increase the spraying area. As the liquid spraying holes 61 of the conical nozzle 60 are gradually exposed from bottom to top, the spraying area is gradually increased. Thus, the effect of dynamically adjusting the spraying area according to different growth stages of the citrus tree 10 is achieved. Furthermore, while improving the utilization rate of water resources, it can ensure that each citrus tree 10 can obtain appropriate water supply, improve the uniformity of spraying, ensure that each citrus tree 10 can obtain appropriate irrigation, and enhance the overall irrigation effect.

[0034] The lifting block 3 can be driven by the driving mechanism to drive the lifting of the conveying pipeline 4, so as to drive the lifting of the conical nozzle 60 through the vertical pipe 5. When the vertical pipe 5 and the conical nozzle 60 descend, the first ring frame 62 descends under the action of its own gravity. When the conical nozzle 60 ascends, it pushes the large circular plate 623 on the first ring frame 62 to move upward. The upward movement of the large circular plate 623 drives the blocking plate 65 to rise together with the conical nozzle 60 through the slider 64. The upward movement of the large circular plate 623 drives the sliding sleeve 621 to rise, so that the entire first ring frame 62 rises to keep in contact with the canopy of the citrus tree 10. In this way, the conical nozzle 60 can always be kept above the citrus tree 10 to realize the dynamic adjustment of the sprinkler irrigation height according to different growth stages of the citrus tree 10, ensure that each citrus tree 10 can be properly irrigated, and enable the first ring frame 62 to always keep in contact with the canopy of the citrus tree 10, ensuring the normal and smooth operation of the operation of dynamically adjusting the sprinkler irrigation area according to different growth stages of the citrus tree 10.

[0035] See Figures 8 - 11 , the driving mechanism includes an inner diamond-shaped rod 71 rotatably connected to the lower part of the support frame 1. A wire winding wheel 72 is connected to the outside of the inner diamond-shaped rod 71. Two front and rear fixed pulleys 73 are rotatably provided on the upper part of the support frame 1. A pull rope 74 is wound around the wire winding wheel 72. The pull rope 74 bypasses the fixed pulley 73 and is connected to the lifting block 3. An outer diamond-shaped rocker 75 is slidably inserted into the inner diamond-shaped rod 71. A locking component for locking the outer diamond-shaped rocker 75 is provided at the lower part of the support frame 1. The locking component includes a ratchet wheel 76 connected to the lower part of the support frame 1. The axis of the ratchet wheel 76 is flush with the axis of the inner diamond-shaped rod 71. A connecting block 77 located outside the inner diamond-shaped rod 71 is connected to the outer diamond-shaped rocker 75. A rotating ring 78 is rotatably connected to the connecting block 77. A pawl 79 is connected to the outer wall of the rotating ring 78. The rotating ring 78 and the pawl 79 are both located at an eccentric position inside the ratchet wheel 76. A notch 710 for the pawl 79 to rotate and disengage from the ratchet wheel 76 is formed on the connecting block 77. A scroll spring 711 is connected between the rotating ring 78 and the connecting block 77. The scroll spring 711 is located inside the rotating ring 78. A positioning block 713 is connected inside the inner diamond-shaped rod 71. A slotted hole 712 matching the positioning block 713 is formed on the outer diamond-shaped rocker 75. The outer diamond-shaped rocker 75 can be limited by the positioning block 713 to prevent the outer diamond-shaped rocker 75 from being completely pulled out of the inner diamond-shaped rod 71.

[0036] Rotating the external diamond-shaped crank 75 clockwise can drive the internal diamond-shaped rod 71 to rotate clockwise, thereby driving the winding wheel 72 to rotate clockwise to wind up the pulling rope 74, so as to pull the lifting block 3 upward. When the external diamond-shaped crank 75 rotates clockwise, it drives the rotating ring 78 and the ratchet pawl 79 to rotate clockwise through the connecting block 77. When the ratchet pawl 79 rotates clockwise and contacts the ratchet teeth on the ratchet wheel 76, the ratchet pawl 79 continues to rotate clockwise and is pushed by the ratchet teeth on the ratchet wheel 76 to rotate itself, and disengages from the ratchet teeth on the ratchet wheel 76. The self-rotation of the ratchet pawl 79 drives the rotating ring 78 to rotate itself and compresses the scroll spring 711. When the ratchet pawl 79 follows the connecting block 77 and rotates clockwise past the ratchet teeth on the ratchet wheel 76, under the reset action of the scroll spring 711, the rotating ring 78 drives the ratchet pawl 79 to rotate itself and reset, and the ratchet pawl 79 then inserts into the tooth groove on the ratchet wheel 76. The ratchet wheel 76 and the connecting block 77 cooperate to limit the ratchet pawl 79 to prevent the ratchet pawl 79 from rotating counterclockwise, thereby locking the connecting block 77 and the external diamond-shaped crank 75, preventing the external diamond-shaped crank 75 from rotating counterclockwise, and further locking the winding wheel 72 to prevent the winding wheel 72 from rotating counterclockwise to release the pulling rope 74. When it is necessary to release the pulling rope 74 to make the lifting block 3 move downward, pull the external diamond-shaped crank 75 outward, thereby driving the ratchet pawl 79 to disengage from the ratchet wheel 76, releasing the lock on the winding wheel 72. The lifting block 3 moves downward under the action of gravity, pulls out the pulling rope 74, and the winding wheel 72 rotates counterclockwise to release the pulling rope 74. Move the external diamond-shaped crank 75 inward, thereby driving the ratchet pawl 79 to insert into the tooth groove on the ratchet wheel 76, and the winding wheel 72 can be locked again. In this way, the operation of driving the lifting block 3 to lift and lower is simple, convenient, and fast.

[0037] Among the row of citrus trees 10, the growth rates and tree heights of each citrus tree 10 are not the same, and the height of a row of ring frames 62 is fixed. It is difficult to ensure that each ring frame 62 contacts each citrus tree 10, resulting in citrus trees 10 with different growth rates and heights being unable to effectively contact the ring frames 62, thus affecting the operation of adjusting the sprinkler irrigation area according to the growth dynamics of the citrus trees 10. In a preferred embodiment, refer to Figure 1 and Figure 7 , in order to avoid the situation where citrus trees 10 with different growth rates and heights cannot effectively contact the ring frames 62, affecting the adjustment of the sprinkler irrigation area according to the growth dynamics of the citrus trees 10, a vertically movable ring frame 81 is slidably arranged between the two vertical rods 624 of the ring frame 62. The ring frame 81 includes an upper ring plate 811, a sliding rod 812, and a lower ring plate 813. The upper ring plate 811 is slidably connected to the two vertical rods 624 of the ring frame 62. A sliding rod 812 is connected to the bottom of the upper ring plate 811 and slidably penetrates through the circular ring plate 625 of the ring frame 62. The bottom end of the sliding rod 812 is connected to the lower ring plate 813, and the lower ring plate 813 is located below the circular ring plate 625 of the ring frame 62. A screw rod 82 is connected between the upper ring plate 811 and the lower ring plate 813 of the ring frame 81. The screw rod 82 slidably penetrates through the circular ring plate 625 of the ring frame 62. A nut 83 is threadedly connected to the screw rod 82, and the nut 83 is rotatably connected to the top of the circular ring plate 625 of the ring frame 81.

[0038] Rotating the nut 83 drives the screw rod 82 to drive the second ring frame 81 to move up and down, so as to adjust the height of the second ring frame 81, so that the second ring frame 81 contacts the citrus tree 10, thereby being able to adapt to citrus trees 10 with different growth speeds and heights. When the citrus tree 10 grows, it will push the second ring frame 81 upward, and then pull the first ring frame 62 upward through the cooperation of the screw rod 82 and the nut 83, realizing the dynamic adjustment of the irrigation area, further ensuring that each citrus tree 10 can be properly irrigated, and further improving the overall irrigation effect.

[0039] See Figure 1 and Figure 12 A telescopic protective sleeve 91 is sleeved on the short hose 42. Elastic bands 92 are connected to both the left and right ends of the telescopic protective sleeve 91. Retaining rings 93 are connected to one side of the outer wall of the hard short pipe 41 close to the short hose 42 and both the left and right sides of the outer wall of the tee pipe 43. The retaining rings 93 can block the elastic bands 92 to position the elastic bands 92, thereby being able to position the telescopic protective sleeve 91 to prevent the telescopic protective sleeve 91 from moving randomly. The telescopic protective sleeve 91 can cover and protect the short hose 42 to prevent the short hose 42 from being exposed to the sun and rain, reducing the risk of hardening, cracking and falling off of the short hose 42, thereby extending the service life of the short hose 42 and reducing the replacement frequency of the short hose 42.

[0040] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention.
