Description

Technical Field

[0001] This invention relates to the field of fruit tree irrigation, specifically a quantitative root irrigation device for fruit trees. Background Technology

[0002] Root drenching refers to applying pesticide solution to the soil like watering, and most plants can be treated this way. Root drenching is best done when the soil is semi-moist and semi-dry. At this temperature, the soil moisture content is moderate, preventing significant dilution of the pesticide and ensuring proper diffusion. When drenching, the goal is to evenly moisten the soil around the roots. Seedlings generally require 50-100ml of pesticide. If using other methods, follow the instructions carefully. Do not water the plant immediately after drenching, as this will dilute the pesticide concentration in the soil and affect its effectiveness. Wait three to four days before watering. However, if pesticide damage occurs after drenching, immediately drench the soil to dilute the pesticide and spray with a growth regulator to alleviate the damage.

[0003] Currently, most existing root irrigation devices are of two types: one can be directly inserted into the soil to irrigate the plant roots, and the other requires the worker to hold it and irrigate the plant roots exposed to the air. The two types of root irrigation devices are not well integrated, which means that workers can only use one type for root irrigation. This cannot meet the needs of workers to irrigate the fruit tree roots both above the soil and directly into the soil. Therefore, a quantitative root irrigation device for fruit trees is proposed to address the above problems. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and solve the problems, this invention proposes a quantitative root irrigation device for fruit trees.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A quantitative root irrigation device for fruit trees, comprising a root irrigation device body, the bottom end of which is funnel-shaped. An annular slot is formed on the bottom end face of the root irrigation device body. A vertical groove is formed on the inner side wall of the annular slot. An annular groove is formed at the top of the inner wall of the vertical groove. A mounting base is provided below the root irrigation device body. An annular insert is fixedly connected to the top of the mounting base. The annular insert is slidably connected to the annular slot. Two limiting sliders are symmetrically fixed to both sides of the inner wall of the annular insert. The limiting sliders are adapted to both the vertical groove and the annular groove. A water collection bucket is fixedly connected to the bottom of the inner wall of the root irrigation device body. The bottom end of the water collection bucket is sleeved with the outer wall of the mounting tube. The top of the mounting tube has symmetrical T-shaped limiting grooves on both sides. An elastic limiting component is slidably connected in the T-shaped limiting groove. The top of the elastic limiting component is fixed to the bottom of the water sealing plate. The top of the mounting base has a circular groove. A top support rod is fixed at the center of the bottom of the circular groove. The top support rod is in contact with the bottom of the water sealing plate. A connecting pipe is fixed to one side of the mounting base. The other end of the connecting pipe is fixedly connected to the arc-shaped irrigation component. Multiple irrigation pipes are evenly fixed to the bottom of the arc-shaped irrigation component. This device allows workers to quickly assemble and disassemble the root irrigation device body and the arc-shaped irrigation component, meeting the needs of workers to irrigate the roots of fruit trees both above the soil and directly into the soil.

[0006] Preferably, the elastic limiting component includes a T-shaped limiting member and a spring. The T-shaped limiting member is slidably connected in the T-shaped limiting groove. The top end of the T-shaped limiting member is fixedly connected to the bottom end of the water sealing plate. A spring is sleeved on the T-shaped limiting member. The top end of the spring is fixedly connected to the top end of the inner wall of the T-shaped limiting groove. The other end of the spring is fixedly connected to the top end of the bottom end of the T-shaped limiting member. When the root dredging device body is used normally and the arc-shaped irrigation component is not required, the cooperation between the elastic limiting component, the water sealing plate, and the fixing plate can ensure that the root dredging device body remains sealed even after the mounting base is detached from the root dredging device body, facilitating the daily use of the root dredging device body by the staff. When the arc-shaped irrigation component is required for irrigation, the root dredging device body and the mounting base can be quickly connected and installed by the elastic limiting component in conjunction with the water sealing plate, the top support rod, the fixing pipe, the annular plug, the limiting slider, and the locking block.

[0007] Preferably, the inner wall of the annular slide groove has two symmetrically formed slots at its bottom, with the included angle between the slots and the vertical slide groove being 90 degrees. The bottom end of the limiting slider is fixed with a locking block, which corresponds to the slot and is made of rubber. By rotating the root dredging device body, the locking block slides relative to the slot within the annular slide groove and fits into the slot. Through the cooperation between the locking block and the slot, as well as the elastic force of the spring, the mounting base and the root dredging device body can be quickly installed and fixed.

[0008] Preferably, the top end face of the installation pipe is provided with an annular sealing groove on the outer side, and the bottom end face of the water sealing plate is fixedly connected with an annular sealing element on the outer side, the annular sealing element corresponding to the annular sealing groove; through the cooperation between the annular sealing element and the annular sealing groove, the joint between the water sealing plate and the installation pipe is sealed, preventing water from leaking out from the gap between the water sealing plate and the installation pipe when water is added to the root irrigation device.

[0009] Preferably, the top end face of the installation pipe is provided with an annular sealing groove two on the inner side, and the bottom end face of the water sealing plate is fixedly connected with an annular sealing element two on the inner side, the annular sealing element two corresponding to the annular sealing groove two; the sealing effect is further enhanced by the cooperation between the annular sealing element two and the annular sealing groove two.

[0010] Preferably, the top of the arc-shaped irrigation component is fixedly connected to an arc-shaped fixing seat. Multiple rotating shafts are evenly rotatably connected within the inner cavity of the arc-shaped fixing seat. A second rotating shaft is provided between every two first rotating shafts. The second rotating shaft is rotatably connected to the inner wall of the arc-shaped fixing seat. The first rotating shaft is connected to the second rotating shaft via a transmission assembly. The bottom end of the first rotating shaft passes through the arc-shaped fixing seat, the arc-shaped irrigation component, and the irrigation pipe, and is fixedly connected to the drill bit. Through a motor cooperating with the first rotating shaft, the second rotating shaft, and the transmission assembly, all first rotating shafts can simultaneously drive the drill bit to rotate. This facilitates the worker directly inserting the irrigation pipe into the soil at the root of the fruit tree, greatly reducing the worker's workload in inserting and removing the irrigation pipe and improving work efficiency. After insertion, water from the root irrigation device flows into the circular groove of the mounting base, then enters the annular irrigation component through the connecting pipe, and finally flows out from the irrigation pipe, achieving direct irrigation of the fruit and vegetable roots beneath the soil.

[0011] Preferably, the transmission assembly includes gear one and gear two. Gear one is sleeved on shaft one, gear one meshes with gear two, gear two is sleeved on shaft two, and a motor is fixedly installed on the top end face of the arc-shaped fixed seat. The top end of one of the shafts one is fixedly connected to the output end of the motor. The motor drives one shaft one to rotate, which causes gear one on shaft one to drive two adjacent gears two to rotate, which in turn causes gear two to drive another shaft one to rotate, and so on, so that all shafts one can drive the drill bit to rotate at the same time, which makes it easier for workers to insert the irrigation pipe directly into the soil at the root of the fruit tree, saving time and effort.

[0012] Preferably, the bottom end face of the irrigation pipe is provided with multiple through holes evenly distributed, and the outer wall of the root irrigation device body is provided with scale lines; the scale lines on the root irrigation device body make it convenient for staff to observe the water volume inside the root irrigation device body, so as to realize quantitative irrigation; the through holes at the bottom end of the irrigation pipe allow water to flow out from the through holes after the irrigation pipe is inserted into the soil, so as to irrigate the roots of the fruit trees.

[0013] The advantages of this invention are:

[0014] 1. This invention enables the quick docking and installation of the root irrigation device body and the mounting base through the cooperation of the elastic limiting component, the water sealing plate, the top support rod, the fixing pipe, the ring plug, the limiting slider and the locking block. Through the cooperation between the elastic limiting component, the water sealing plate and the fixing plate, the root irrigation device body can remain sealed even after the mounting base is separated from the root irrigation device body, which is convenient for the staff to use the root irrigation device body in daily life. This device makes it easy for the staff to quickly disassemble and assemble the root irrigation device body and the arc-shaped irrigation component, which meets the staff's needs to irrigate the fruit tree roots both above the soil and directly into the soil.

[0015] 2. This invention uses a motor to drive a rotating shaft to rotate, which in turn causes a gear on the rotating shaft to drive two adjacent gears to rotate, which in turn causes another rotating shaft to rotate, and so on, so that all rotating shafts can drive the drill bit to rotate simultaneously. This makes it easier for workers to insert the irrigation pipe directly into the soil at the root of the fruit tree, greatly reducing the workload of workers inserting and removing the irrigation pipe and improving work efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8As shown, a quantitative root irrigation device for fruit trees includes a root irrigation device body 1. The bottom end of the root irrigation device is funnel-shaped. An annular slot 5 is formed on the bottom end face of the root irrigation device body 1. A vertical groove 6 is formed on the inner side wall of the annular slot 5. An annular groove 7 is formed on the top of the inner wall of the vertical groove 6. A mounting base 2 is provided below the root irrigation device body 1. An annular insert 9 is fixedly connected to the top of the mounting base 2. The annular insert 9 is slidably connected to the annular slot 5. Two limiting sliders 10 are symmetrically fixed to both sides of the inner wall of the annular insert 9. The limiting sliders 10 are adapted to both the vertical groove 6 and the annular groove 7. A certain component is fixedly connected to the bottom of the inner wall of the root irrigation device body 1. A water collection hopper 12 is fitted at its bottom end to the outer wall of an installation pipe 13. T-shaped limiting grooves 15 are symmetrically provided on both sides of the top end of the installation pipe 13. An elastic limiting component is slidably connected in the T-shaped limiting groove 15. The top end of the elastic limiting component is fixedly connected to the bottom end of a water sealing plate 14. A circular groove is provided at the top end of the mounting base 2. A top support rod 20 is fixed at the center of the bottom of the inner cavity of the circular groove. The top support rod 20 is in contact with the bottom end of the water sealing plate 14. A connecting pipe 3 is fixedly connected to one side of the mounting base 2. The other end of the connecting pipe 3 is fixedly connected to an arc-shaped irrigation component 4. Multiple irrigation pipes 24 are evenly fixed at the bottom end of the arc-shaped irrigation component 4.During operation, when the root irrigator body 1 is used normally and the arc-shaped irrigation component 4 is not required, simply rotate and slide the mounting base 2 out from the bottom of the root irrigator body 1. At this time, the top support rod 20 moves away from the sealing plate 14, causing the sealing plate 14 to slide downward under the elastic force of the elastic limiting component and fit against the top of the mounting tube 13, completing the seal. After adding water to the root irrigator body 1, the pressure at the bottom of the water causes the sealing plate 14 and the mounting tube 13 to fit tightly together, further ensuring the sealing effect between the two. The worker can hold the root irrigator body 1 to directly irrigate the roots of the fruit trees exposed to the air. When the arc-shaped irrigation component 4 is needed for irrigation, insert the irrigation tube 24 on the arc-shaped irrigation component 4 directly into the soil along the roots of the fruit trees. After the irrigation tube 24 is inserted, the worker slides the limiting slider 10 along the vertical groove 6, causing the annular insert 9 to slide into the annular slot 5 until the limiting slider 10 fits against the top of the vertical groove 6, and then... By rotating the root irrigation device body 1, the limiting slider 10 slides into the annular groove 7. Simultaneously, as the annular insert 9 slides upwards, the mounting base 2 drives the top support rod 20 to slide into the mounting tube 13, where it fits against the bottom of the water sealing plate 14, causing the water sealing plate 14 to slide upwards. Through the elastic force of the elastic limiting component and the limiting slider 10, the root irrigation device body 1 and mounting base 2 can be quickly connected and installed. Water is then added to the root irrigation device body 1. After entering the water collection hopper 12 at the bottom of the root irrigation device body 1, the water flows from the mounting tube 13 into the circular groove of the mounting base 2, then through the connecting pipe 3 into the annular irrigation component, and finally into the irrigation pipe 24 and out through the through hole 31 at the bottom of the irrigation pipe 24, directly irrigating the roots of fruits and vegetables below the soil. This device allows workers to quickly assemble and disassemble the root irrigation device body 1 and the arc-shaped irrigation component 4, meeting the needs of workers to irrigate the roots of fruit trees both above the soil and directly into the soil.

[0028] The elastic limiting component includes a T-shaped limiting member 16 and a spring 17. The T-shaped limiting member 16 is slidably connected within the T-shaped limiting groove 15. The top end of the T-shaped limiting member 16 is fixedly connected to the bottom end of the water sealing plate 14. The spring 17 is sleeved on the T-shaped limiting member 16. The top end of the spring 17 is fixedly connected to the top end of the inner wall of the T-shaped limiting groove 15, and the other end of the spring 17 is fixedly connected to the top end of the bottom end of the T-shaped limiting member 16. During operation, when the root irrigation device body 1 is used normally and the arc-shaped irrigation component 4 is not required, the water sealing plate 14 slides downwards under the elastic force of the compression spring 17 and is connected to the installation pipe. The top of 13 is sealed to prevent water from leaking out from the gap between the sealing plate 14 and the mounting tube 13 when water is added to the root irrigation device body 1. When the arc-shaped irrigation component 4 is needed for irrigation, the mounting base 2 drives the top support rod 20 to slide into the mounting tube 13 and fit against the bottom of the sealing plate 14 while the annular insert 9 slides up. The sealing plate 14 is then slid upward until the locking block 11 slides into the slot 8 and stops. At this time, the spring 17 is in a compressed state. Through the elastic force of the spring 17, the limiting slider 10 and the locking block 11 can achieve quick docking and installation between the root irrigation device body 1 and the mounting base 2.

[0029] The inner wall of the annular slide groove 7 has two symmetrical slots 8 at its bottom. The angle between the slots 8 and the vertical slide groove 6 is 90 degrees. The bottom end of the limiting slider 10 is fixed with a locking block 11, which corresponds to the slot 8. The locking block 11 is a rubber component. During operation, the locking block 11 slides relative to the slot 8 in the annular slide groove 7 and fits against the slot 8 by rotating the root irrigation device body 1. Through the cooperation between the locking block 11 and the slot 8 and the elastic force of the spring 17, the mounting base 2 and the root irrigation device body 1 can be quickly installed and fixed.

[0030] The top end face of the installation pipe 13 is provided with an annular sealing groove 18 on the outer side, and the bottom end face of the water sealing plate 14 is fixed with an annular sealing element 21 on the outer side. The annular sealing element 21 corresponds to the annular sealing groove 18. During operation, the cooperation between the annular sealing element 21 and the annular sealing groove 18 can seal the joint between the water sealing plate 14 and the installation pipe 13, preventing water from leaking out from the gap between the water sealing plate 14 and the installation pipe 13 when water is added to the root irrigation device body 1.

[0031] The top end face of the installation pipe 13 is provided with an annular sealing groove 19 on the inner side, and the bottom end face of the water sealing plate 14 is fixed with an annular sealing element 22 on the inner side. The annular sealing element 22 corresponds to the annular sealing groove 19. During operation, the sealing effect is further enhanced by the cooperation between the annular sealing element 22 and the annular sealing groove 19.

[0032] The top of the arc-shaped irrigation component 4 is fixedly connected to an arc-shaped fixing seat 23. Multiple rotating shafts 26 are evenly rotatably connected within the inner cavity of the arc-shaped fixing seat 23. A rotating shaft 29 is provided between every two rotating shafts 26. The rotating shaft 29 is rotatably connected to the inner wall of the arc-shaped fixing seat 23. The rotating shafts 26 are connected to the rotating shafts 29 via a transmission assembly. The bottom end of the rotating shaft 26 passes through the arc-shaped fixing seat 23, the arc-shaped irrigation component 4, and the irrigation pipe 24, and is fixedly connected to the drill bit 30. During operation, when irrigation is required using the arc-shaped irrigation component 4, the arc-shaped irrigation component 4 is placed against... The fruit tree roots are placed vertically, and the motor 25 is started. Through the motor 25, in conjunction with the rotating shaft 26, rotating shaft 29 and the transmission assembly, all rotating shafts 26 can drive the drill bit 30 to rotate simultaneously. This makes it easy for workers to directly insert the irrigation pipe 24 into the soil at the root of the fruit tree, greatly reducing the workload of workers inserting and removing the irrigation pipe 24 and improving work efficiency. After insertion, the water in the root irrigation device body 1 flows into the circular groove of the mounting base 2, then enters the annular irrigation component through the connecting pipe 3, and finally flows out from the irrigation pipe 24 to directly irrigate the roots of fruits and vegetables under the soil.

[0033] The transmission assembly includes gear 27 and gear 28. Gear 27 is sleeved on shaft 26 and meshes with gear 28. Gear 28 is sleeved with shaft 29. Motor 25 is fixedly installed on the top end face of the arc-shaped fixed seat 23. The top end of one shaft 26 is fixedly connected to the output end of motor 25. During operation, motor 25 drives one shaft 26 to rotate, which causes gear 27 on shaft 26 to drive two adjacent gears 28 to rotate, which in turn causes gear 28 to drive another shaft 26 to rotate, and so on, so that all shafts 26 can drive the drill bit 30 to rotate simultaneously, making it convenient for workers to insert irrigation pipe 24 directly into the soil at the root of the fruit tree.

[0034] The bottom end face of the irrigation pipe 24 is evenly provided with multiple through holes 31, and the outer wall of the root irrigation device body 1 is provided with scale lines. During operation, the scale lines on the root irrigation device body 1 make it easy for the staff to observe the water volume inside the root irrigation device body 1 and realize quantitative irrigation. Through the through holes 31 at the bottom end of the irrigation pipe 24, after the irrigation pipe 24 is inserted into the soil, the water flows out from the through holes 31 to irrigate the roots of the fruit trees.

[0035] Working principle: When the root dredging device body 1 is in normal use and the arc-shaped irrigation component 4 is not needed, simply rotate and slide the mounting base 2 out from the bottom of the root dredging device body 1. At this time, the top support rod 20 moves away from the sealing plate 14, causing the sealing plate 14 to slide downward under the elastic force of the compression spring 17 and fit against the top of the mounting tube 13. At the same time, the annular seal 1 21 and the annular seal 22 fit against the annular sealing groove 18 and the annular sealing groove 2 19 respectively, thus sealing the joint between the sealing plate 14 and the mounting tube 13. This prevents water from leaking out from the gap between the sealing plate 14 and the mounting tube 13 when water is added to the root dredging device body 1. After water is added to the root dredging device body 1, the pressure at the bottom of the water seals the water. The plate 14 and the installation pipe 13 fit tightly together, further ensuring the sealing effect between them. Workers can hold the root irrigation device body 1 to directly irrigate the roots of the fruit trees. When the curved irrigation component 4 is needed, it is placed vertically against the roots of the fruit tree, and the motor 25 is started. The motor 25 drives one shaft 26 to rotate, causing gear 27 on shaft 26 to drive two adjacent gears 28 to rotate. Gears 28 then drive another shaft 26 to rotate, and so on, so that all shafts 26 simultaneously drive the drill bit 30 to rotate. This makes it easier for workers to directly insert the irrigation pipe 24 into the soil at the roots of the fruit trees, greatly reducing the difficulty of insertion and removal. The increased workload of irrigation pipe 24 improves work efficiency. After the irrigation pipe 24 is inserted, the worker slides the limiting slider 10 along the vertical groove 6, causing the annular insert 9 to slide into the annular slot 5 until the limiting slider 10 is in contact with the top of the vertical groove 6. Then, by rotating the root irrigation device body 1, the limiting slider 10 and the locking block 11 slide together into the annular groove 7 until the locking block 11 is in contact with the slot 8 after rotating 90 degrees. At the same time as the annular insert 9 slides upward, the mounting base 2 drives the top support rod 20 to slide into the mounting pipe 13 and into contact with the bottom of the sealing plate 14, and drives the sealing plate 14 to slide upward until the locking block 11 slides into the slot 8 and stops. At this time, the spring 17 is in a compressed state. The elastic force of spring 17, in conjunction with the limiting slider 10 and the locking block 11, enables the quick docking and installation of the root irrigation device body 1 and the mounting base 2. Water is then added to the root irrigation device body 1. After entering the water collection hopper 12 at the bottom of the root irrigation device body 1, the water flows from the mounting pipe 13 into the circular groove of the mounting base 2, then through the connecting pipe 3 into the annular irrigation component, and finally into the irrigation pipe 24 and out through the through hole 31 at the bottom of the irrigation pipe 24, thus directly irrigating the roots of fruits and vegetables under the soil. This device facilitates the quick assembly and disassembly of the root irrigation device body 1 and the arc-shaped irrigation component 4 by the staff, meeting the needs of the staff to irrigate the roots of fruit trees both above the soil and directly into the soil.
