Description

Technical Field

[0001] The invention relates to the technical field of water and fertilizer conveying equipment, and in particular to a water and fertilizer system for fruit tree planting and a use method thereof. Background Art

[0002] When raising fruit tree seedlings, it is necessary to fertilize the fruit trees according to their varieties, sizes, growth period differences, and interference from pests and diseases, so that the fruit trees can absorb fertilizers rich in different elements to meet their normal growth needs. This is especially true during the cultivation stage before transplanting the fruit trees. Adequate nutrient supply needs to be ensured during the rapid growth period of the fruit tree roots.

[0003] The traditional method of fertilizing fruit trees is usually to directly bury fertilizer in the soil, and the fertilizer is absorbed by the fruit tree roots through the infiltration of the fertilizer in the soil. Although this fertilization method is relatively simple, some of the water and fertilizer will remain in the soil gaps during the infiltration process, making it impossible for the fruit tree roots to effectively absorb the nutrients in the fertilizer, which affects the normal growth of the fruit tree. In response to the above problems, there are already good solutions in the existing technology, such as a fruit tree root topdressing injection device with patent number: CN214155373U. By setting a U-shaped cannula, one end of the U-shaped cannula is inserted into the soil by external force when injecting water and fertilizer, thereby achieving direct fertilization of the fruit tree roots, ensuring that the fruit tree roots effectively absorb the nutrients in the fertilizer, and then promoting the normal growth of the fruit tree. However, there is still the following defect: in order to directly inject water and fertilizer near the fruit tree roots, it is necessary to first break the ground. During the groundbreaking process, the staff moves the drill rod to the corresponding position and drives the drill rod into the ground. On the one hand, during the large-scale cultivation stage of fruit trees before transplanting, due to the large number of fruit trees, the process of manually applying water and fertilizer to each fruit tree one by one during the rapid growth period of the fruit trees is time-consuming and labor-intensive, and cannot guarantee timely nutrient supply to the roots of all fruit trees; on the other hand, when the roots of the fruit trees spread and grow upward, the depth of the drill rod inserted into the ground cannot be accurately controlled, which will cause mechanical damage to the roots of the fruit trees, and also affect the effective absorption of water, fertilizer and nutrients by the roots of the fruit trees, thereby affecting the normal growth of the fruit trees.

[0004] Therefore, in order to solve the above problems, a water-fertilizer system and a method for using the system are proposed for growing fruit trees. Summary of the Invention

[0005] The purpose of the present invention is to provide a water and fertilizer system for fruit tree planting and a method for use, which solves the problem that when cultivating fruit trees in large quantities before transplanting, it is time-consuming and labor-intensive to apply water and fertilizer to the fruit trees one by one manually, and the root system of the fruit trees may be mechanically damaged due to the inability to accurately control the drilling depth, thereby affecting the normal growth of the fruit trees. By providing an injection component, a drive component, and an adjustment component, it is possible to use an external controller to fertilize multiple fruit trees simultaneously, so that the root system of the fruit trees can obtain nutrients in a timely manner during the rapid growth period. On the one hand, it can reduce the intensity of work, so that the needle can perform intermittent soil breaking work, and during the soil breaking process, the movement of the needle in the sleeve can be used to inject water and fertilizer into the soil in small amounts and multiple times; on the other hand, it can control the soil breaking depth to avoid mechanical damage to the root system of the fruit trees, thereby ensuring the normal growth of the fruit trees.

[0006] To achieve the above object, the present invention provides the following technical solutions: A water and fertilizer system for fruit tree planting includes two spliced mounting bases, an injection assembly, a drive assembly, a motor, an adjustment assembly and an electric push rod. The mounting base includes a mounting plate, a surface array of the mounting plate is provided with a plurality of through holes, the injection assembly is hinged inside the through holes, the drive assembly is arranged on the mounting base, the motor is arranged on the mounting base and a gear is arranged at the output end, when the motor drives the gear to rotate, it drives the drive assembly to rotate, and when the drive assembly rotates, it intermittently squeezes the injection assembly, the adjustment assembly is arranged on the drive assembly, the electric push rod is arranged on the drive assembly and the output end is connected to the adjustment assembly, when the output end of the electric push rod moves downward or upward, it drives the lower end of the injection assembly to move up or down respectively, and when the lower end of the injection assembly moves up or down, it moves away from or closes to the fruit tree synchronously.

[0007] Preferably, the injection assembly includes a sliding sleeve, a sleeve, an insertion needle, a block, a piston 1, a spring 1, a spring 2 and an infusion tube 1. The sliding sleeve is hinged to the inside of the through hole, the sleeve is arranged through the sliding sleeve, the insertion needle and the piston 1 are both arranged inside the sleeve and are connected to each other, the insertion needle is hollow and has an injection hole at the lower end, the block is arranged at the upper end of the sleeve, the spring 1 is arranged between the sliding sleeve and the block and is connected to the sleeve, the spring 2 is arranged inside the sleeve and connected to the sleeve and the piston 1, the infusion tube 1 is arranged through the sleeve, and the stiffness of the spring 1 is less than that of the spring 2.

[0008] As can be seen, forced soil removal, which causes the separation of soil clods, can pull on the roots of fruit trees. There are many ways to avoid root damage caused by forced soil removal. Common methods include sprinkling water on the ground to moisten the soil and reduce stress during the process, or embedding water and fertilizer pipes directly in the soil to deliver water and fertilizer to specific locations. This solution was adopted, considering that water and fertilizer need to be applied after soil removal. Sprinkling water on the ground will dilute the concentration of water and fertilizer, affecting fertilization effectiveness. Furthermore, embedding water and fertilizer pipes in the soil will block the natural growth path of the fruit tree roots, also affecting normal growth. By means of the injection hole opened at the lower end of the pin and the infusion tube 1 provided on the sleeve, water and fertilizer can be applied during the soil breaking process, and the soil can be moistened by the water and fertilizer, thereby reducing the stress during soil breaking and achieving effective protection of the root system of the fruit tree. Furthermore, since the stiffness of the spring 1 is less than that of the spring 2, the spring 2 will not deform before the lower end of the pin contacts the ground, that is, the water and fertilizer will not flow out through the injection hole between the pin and the ground, thus avoiding the splashing of water and fertilizer, and enabling the water and fertilizer to be concentratedly injected near the lower end of the pin.

[0009] Preferably, the mounting seat also includes an arc-shaped plate 1 and a guide rail, the arc-shaped plate 1 is arranged on the mounting plate, the guide rail is arranged on the arc-shaped plate 1, the driving assembly includes an arc-shaped tooth plate, a driving plate and a pressure plate, the arc-shaped plate 1 is arranged on the mounting seat, the guide rail is arranged on the arc-shaped plate 1, the arc-shaped tooth plate is arranged on the guide rail and meshes with the gear, two arc-shaped tooth plates are provided and spliced by bolts, the driving plate is arranged on the arc-shaped tooth plate, the pressure plate is arranged on the driving plate, the surface of the block is arranged in an arc shape, and the pressure plate is inclined along the clockwise direction close to the side of the block.

[0010] By adopting the above scheme, during the rotation of the arc-shaped tooth plate, the connection with the driving plate and the pressure plate can be used to squeeze the block, so that the block can smoothly drive the pin to perform the soil-piercing action after being squeezed; and when the pressure plate and the block are misaligned during the rotation of the arc-shaped tooth plate, the elastic force of spring one and spring two can be used to drive the sleeve and the pin to reset. As the arc-shaped tooth plate continues to rotate, intermittent soil-piercing action can be achieved, leaving time for water and fertilizer to wet the soil, further avoiding the stress of forced soil breaking that pulls the roots of fruit trees and affects the normal growth of the roots of fruit trees, and the motor can be controlled to start and stop by the controller, so as to achieve the purpose of synchronously injecting water and fertilizer to the roots of multiple fruit trees in the cultivation area, effectively reducing the workload of the staff, and being able to provide timely nutrient supply to the roots of multiple fruit trees when the roots of fruit trees are growing rapidly, further ensuring the normal growth of fruit trees.

[0011] Preferably, the adjustment assembly includes an arc-shaped plate 2, a hinged rod, a slider, a U-shaped plate and a limit piece. The arc-shaped plate 2 is arranged inside the arc-shaped plate 1 and connected to the output end of the electric push rod. The upper end of the hinged rod is arranged on the arc-shaped plate 2. The slider is arranged at the lower end of the hinged rod and is socketed with a pin. The U-shaped plate is hinged to the lower end of the hinged rod. A notch is provided at the lower end of the arc-shaped plate 1. The hinged rod is arranged to pass through the notch. The limit piece is arranged on the U-shaped plate and connected to the arc-shaped plate 1.

[0012] As can be seen, the roots of fruit trees spread outward as they grow, and some of them grow upward. Considering that inserting the pins at a fixed depth in the soil could damage the tree's roots, this solution was adopted. The hinged rod is designed to drive the lower end of the pin upward as the curved plate 2 moves downward. Because the pin's upward trajectory is curved, the greater the upward deflection angle, the shallower the pin's penetration into the soil when the pressure plate squeezes the block. This ensures effective fertilization while preventing the pins from damaging the tree's roots, thus ensuring normal growth.

[0013] Preferably, the limiting member includes a fixed rod, a liquid storage box, a liquid outlet pipe, a second piston, a movable rod and a second infusion tube. The fixed rod is arranged inside the first arc-shaped plate, the liquid storage box is arranged at the lower end of the fixed rod, the liquid outlet pipe is arranged through the liquid storage box, the second piston is arranged inside the liquid outlet pipe, the movable rod is arranged on the U-shaped plate and connected to the second piston, the second infusion tube is arranged through the liquid storage box, the bottom of the liquid storage box is provided with a first liquid outlet hole, and the bottom of the liquid outlet tube is provided with a second liquid outlet hole.

[0014] By adopting the above solution, the lower end of the hinged rod can be limited in the horizontal direction when the arc plate 2 moves downward. Since the fruit tree needs to be fertilized from the root center to the root edge to promote normal growth, and the root edge has more root hairs, which are the main part of the root system that absorbs fertilizer, when the root system of the fruit tree grows rapidly in spring and summer, the root edge needs to be fertilized. During the upward movement of the pin, the number of the second liquid outlet holes located between the piston 2 and the liquid storage box can be increased, so that the water and fertilizer can drip onto the soil between the pin and the fruit tree. In addition, more water and fertilizer can be applied to the position farther away from the root center of the fruit tree per unit time, thus achieving a wide range of nutrient supply to the fruit tree root system.

[0015] Preferably, the first and second liquid outlet holes are both provided in plurality, the apertures of the first liquid outlet hole are set to be equal, and the apertures of the second liquid outlet hole are set to increase in a direction from the liquid storage box to the pin connected thereto.

[0016] As can be seen, the center of the fruit tree's root system has a weaker ability to absorb fertilizer. Excessive fertilization will damage the fruit tree's root system, resulting in a decrease in the fruit tree's ability to absorb fertilizer, which in turn affects the normal growth of the fruit tree. Therefore, this solution is adopted. By providing liquid outlet hole 1 and liquid outlet hole 2, the water and fertilizer flowing out of liquid outlet hole 1 and liquid outlet hole 2 near the liquid storage box can drip into the soil near the fruit tree's roots in small amounts and multiple times. The water and fertilizer are absorbed by the fruit tree's roots through natural osmosis, which can avoid overfertilization and affect the normal growth of the fruit tree.

[0017] Preferably, a one-way valve 1 is provided on the infusion tube 1, a one-way valve 2 is provided through the interior of the piston 1, and the one-way valve 2 is connected to the interior of the insertion needle.

[0018] By adopting the above solution, the water and fertilizer inside the sleeve can be pressed into the interior of the needle by the one-way valve 2 during the downward movement of the sleeve along the axial direction, and can eventually flow out from the injection hole, so that the water and fertilizer can be transported to the holes pierced by the needle in the soil, thereby fertilizing the root system of the fruit tree, enabling the root system of the fruit tree to effectively absorb the water and fertilizer, and further ensuring the normal growth of the fruit tree.

[0019] A method for using the water-fertilizer system for fruit tree planting, comprising the following steps: S1. Splice the two mounting bases in a circular shape around the fruit tree and then splice the two arc-shaped tooth plates. S2, water and fertilizer are transported to the corresponding liquid storage box through two liquid infusion pipes 2, and the water and fertilizer naturally flow out through the liquid outlet hole 1 and the liquid outlet hole 2 to the vicinity of the fruit tree root system; S3. Start the motor, which drives the arc-shaped toothed plate to rotate via the gears. The motor, through the connection between the drive plate and the pressure plate, drives the pressure plate to rotate and squeeze the block. When the block is squeezed, the sleeve moves along the axis and squeezes the piston 1 via the spring 2, causing the pin to penetrate the soil along the axis and transport water and fertilizer. S4. During the growth of the fruit tree, the electric push rod is started. The output end of the electric push rod drives the arc plate 2 to move downward, and the hinged action of the hinged rod and the limiting action of the limiting member are used to drive the slider away from the fruit tree. When the slider moves away from the fruit tree, the pin is driven to move upward and the exposed range of the liquid outlet hole 2 is increased. S5. Start the motor again and repeat the soil-drilling and water and fertilizer delivery work to achieve large-scale fertilization of the fruit tree root system.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the provided injection assembly, drive assembly and adjustment assembly, when cultivating fruit trees in large quantities to a growth state ready for transplanting, the injection assembly, drive assembly and adjustment assembly around each fruit tree can be controlled by an external controller to work synchronously, thereby reducing the workload of staff in fertilizing the fruit trees one by one, and ensuring timely nutrient supply to the roots of the fruit trees when the roots grow rapidly in spring and summer; and when breaking the soil at the edge of the root system of the fruit tree, the intermittent soil-piercing action of the needle can be used to apply water and fertilizer in small amounts multiple times, so that the water and fertilizer gradually wet the soil, which can avoid the fruit tree roots being pulled when the soil blocks are separated due to the needle breaking the soil and affecting the natural distribution of the fruit tree roots, and at the same time, when the fruit tree roots grow rapidly around in spring and summer, the distance between the lower end of the injection assembly and the fruit tree is increased, so as to achieve the purpose of applying water and fertilizer to the position where the root hairs at the edge of the root system of the fruit tree are more distributed, so that the fruit tree roots can effectively absorb the water and fertilizer, and ensure the normal growth of the fruit tree.

[0021] 2. By providing the sliding sleeve, adjusting component and limiting part, and by hingedly setting the sliding sleeve inside the through hole, the adjusting component can drive the lower end of the pin to move upward away from the fruit tree. When the root system of the fruit tree grows rapidly in all directions, the distance between the lower end of the pin and the ground is increased, thereby achieving the effect of reducing the depth of the pin breaking through the soil, thereby avoiding mechanical damage to the root system of the fruit tree when the pin breaks through the soil, and effectively ensuring the normal growth of the fruit tree.

[0022] 3. By providing the liquid storage box, the liquid outlet pipe, the second piston and the movable rod, the sleeve can be limited in the horizontal direction, and water and fertilizer can be dripped onto the soil surface in small amounts and multiple times during the growth process of the fruit tree from individual planting and cultivation to transplanting. At the same time, as the root system of the fruit tree grows rapidly, the number of the second liquid outlet holes 2 opened on the liquid outlet pipe and located between the piston and the liquid storage box can be increased as the lower end of the insertion rod moves away from the fruit tree, thereby expanding the range of water and fertilizer dripping onto the soil surface, and utilizing the penetration effect of water and fertilizer to supply nutrients to the root system of the fruit tree between the fruit tree and the insertion needle.

[0025] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 9 The present invention provides a water-fertilizer system for fruit tree planting and a method of use. The technical solution is as follows: For details, please refer to Figure 1 and Figure 2 A water and fertilizer system for fruit tree planting includes two spliced mounting bases 1, an injection assembly 2, a drive assembly 3, a motor 4, an adjustment assembly 5 and an electric push rod 6. The mounting base 1 includes a mounting plate 11, and the mounting base 1 also includes an arc-shaped plate 12 and a guide rail 13. The arc-shaped plate 12 is arranged on the mounting plate 11, the guide rail 13 is arranged on the arc-shaped plate 12, and the motor 4 is arranged on the arc-shaped plate 12. The entire device is mounted in a spliced manner, and can be put around the fruit tree. When the fruit tree is cultivated to be transplanted, the entire device is easy to disassemble.

[0027] As an embodiment of the present invention, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The surface array of the mounting plate 11 is provided with a plurality of through holes 111. The injection assembly 2 is hinged inside the through hole 111. The injection assembly 2 includes a sleeve 21, a sleeve 22, a pin 23, a stopper 24, a piston 25, a spring 26, a spring 27 and an infusion tube 28. The sleeve 21 is hinged inside the through hole 111. The sleeve 22 passes through the sleeve 21. The pin 23 and the piston 25 are both sleeved inside the sleeve 22 and sleeved with each other. The pin 23 is hollow and has an injection hole 231 at the lower end. The stopper 24 is arranged at the upper end of the sleeve 22, the spring 1 26 is arranged between the sliding sleeve 21 and the stopper 24 and is sleeved with the sleeve 22, the spring 27 is arranged inside the sleeve 22 and is connected to the sleeve 22 and the piston 1 25, the infusion tube 1 28 is arranged through the sleeve 22, the stiffness of the spring 1 26 is less than the stiffness of the spring 27; a one-way valve 1 281 is arranged on the infusion tube 1 28, and a one-way valve 251 is arranged inside the piston 1 25, and the one-way valve 251 is connected to the inside of the pin 23.

[0028] Under the above setting mode, when the stopper 24 squeezes the sleeve 22 along the axial direction of the sleeve 22, the sleeve 22 can move downward along its own axial direction, and can squeeze the spring 1 26 and the spring 2 27 during the downward movement. When the spring 27 is squeezed, it can drive the piston 1 25 and the pin 23 to move downward with the sleeve 22. When the lower end of the pin 23 contacts the ground, as the sleeve 22 continues to move downward, the spring 2 27 begins to contract, and the piston 1 25 moves upward relative to the sleeve 22. During this process, the water and fertilizer inside the sleeve 22 will be squeezed into the pin 23 through the one-way valve 2 251, and finally flow out from the injection hole 231 to the ground. The water and fertilizer gradually wet the ground during the process of infiltrating into the ground, thereby ensuring that the subsequent pin 23 can be smoothly inserted into the soil, avoiding the situation where forced breaking of the soil affects the normal growth of the fruit tree root system.

[0029] As an embodiment of the present invention, refer to Figure 1 、 Figure 2 and Figure 5The driving assembly 3 is arranged on the mounting base 1, and a gear 41 is provided at the output end of the motor 4. When the motor 4 drives the gear 41 to rotate, the driving assembly 3 is driven to rotate. When the driving assembly 3 rotates, the injection assembly 2 is intermittently squeezed. The driving assembly 3 includes an arcuate tooth plate 31, a driving plate 32 and a pressure plate 33. The guide rail 13 is arranged on the arcuate plate 12. The arcuate tooth plate 31 is arranged on the guide rail 13 and meshes with the gear 41. There are two arcuate tooth plates 31 and they are spliced by bolts. The driving plate 32 is arranged on the arcuate tooth plate 31, and the pressure plate 33 is arranged on the driving plate 32. The surface of the stopper 24 is arranged in an arc shape, and the pressure plate 33 is inclined along the clockwise direction (clockwise direction of the top view) close to the side of the stopper 24.

[0030] Under the above setting mode, the two arc-shaped tooth plates 31 can be spliced and connected to form a ring gear 41. When the motor 4 is working, the meshing of the gear 41 and the arc-shaped tooth plate 31 can be used to drive the arc-shaped tooth plate 31 to rotate. When the arc-shaped tooth plate 31 rotates, it drives the driving plate 32 to rotate. When the driving plate 32 rotates, it drives the pressure plate 33 to rotate. During the rotation of the pressure plate 33, the block 24 is squeezed by its own inclined surface, so that the block 24 can move along the axial direction of the sleeve 22 after being squeezed, thereby ensuring the normal progress of the earth-breaking work. When the pressure plate 33 is misaligned with the block 24, the spring 26 and The springs 27 are reset by their own elastic force, and in the process of their respective reset, they drive the sleeve 22 and the pin 23 to reset respectively. In the process of the pin 23 resetting, the piston 1 25 follows the pin 23 to move to the position of the lower end of the sleeve 22, and in the process of movement, the water and fertilizer are pumped into the interior of the sleeve 22 for storage through the infusion tube 1 28 through the unidirectional conduction effect of the one-way valve 1 281 and the one-way valve 2 251. When the stopper 24 is squeezed again during the continuous rotation of the pressure plate 33, the pin 23 can repeat the soil-piercing action and pierce the same position each time.

[0031] As an embodiment of the present invention, refer to Figure 1 、 Figure 5 、 Figure 6 Figure 8 and Figure 9The adjusting component 5 is arranged on the driving component 3, the electric push rod 6 is arranged on the driving component 3 and the output end is connected to the adjusting component 5, and when the output end of the electric push rod 6 moves downward or upward, the lower end of the injection component 2 is driven to move up or down respectively, and the lower end of the injection component 2 moves up or down synchronously away from or close to the fruit tree. The adjusting component 5 includes an arc-shaped plate 2 51, a hinged rod 52, a slider 53, a U-shaped plate 54 and a limiter 55. The arc-shaped plate 2 51 is arranged inside the arc-shaped plate 12 and is connected to the output end of the electric push rod 6, the upper end of the hinged rod 52 is arranged on the arc-shaped plate 2 51, the slider 53 is arranged at the lower end of the hinged rod 52 and is socketed with the pin 23, the U-shaped plate 54 is hinged to the lower end of the hinged rod 52, and a slot 121 is provided at the lower end of the arc-shaped plate 12, the hinged rod 52 is arranged through the slot 121, and the limiter 55 is arranged on the U-shaped plate 54 and connected to the arc-shaped plate 12.

[0032] As the fruit tree grows, its roots will spread outwards. Under the above-mentioned setting conditions, the electric push rod 6 is started, and the output end of the electric push rod 6 drives the arc plate 2 51 to move downwards. During the downward movement of the arc plate 2 51, the upper end of the hinged rod 52 is driven downwards. Since the lower end of the hinged rod 52 is connected to the slider 53 and the limiter 55, the slider 53 can be driven horizontally away from the fruit tree during the downward movement of the upper end of the hinged rod 52. Since the slider 53 is sleeved with the pin 23, and the sleeve 21 is hinged Inside the through hole 111, the slider 53 can drive the pin 23 to move upward in the process of moving away from the fruit tree, so that the lower end of the pin 23 is away from the fruit tree. When the motor 4 is started again to drive the pin 23 to pierce the soil, the piercing position can be moved away from the fruit tree, and due to the hinged effect of the sleeve 22, the lower end of the pin 23 will move upward along an arc trajectory, so that the pressure plate 33 reduces the piercing depth of the pin 23 in the process of following the drive plate 32 to rotate and squeeze the block 24, thereby preventing the pin 23 from damaging the root system of the fruit tree.

[0033] As an embodiment of the present invention, refer to Figure 6 and Figure 7 The limiting member 55 includes a fixed rod 551, a liquid storage box 552, a liquid outlet pipe 553, a second piston 554, a movable rod 555 and a second infusion pipe 556. The fixed rod 551 is arranged inside the arc-shaped plate 12, the liquid storage box 552 is arranged at the lower end of the fixed rod 551, the liquid outlet pipe 553 is arranged through the liquid storage box 552, the second piston 554 is arranged inside the liquid outlet pipe 553, the movable rod 555 is arranged on the U-shaped plate 54 and connected to the second piston 554, the second infusion pipe 556 is arranged through the liquid storage box 552, and a liquid outlet hole 5521 is provided at the bottom of the liquid storage box 552, and a liquid outlet hole 5531 is provided at the bottom of the liquid outlet pipe 553.

[0034] Under the above-mentioned setting conditions, when the upper end of the hinged rod 52 moves downward, the lower end will drive the U-shaped plate 54 away from the fruit tree. In the process of the U-shaped plate 54 moving away from the fruit tree, it can drive the movable rod 555 to move toward the outside of the liquid outlet pipe 553, and can increase the number of liquid outlet holes 5531 located between the piston 554 and the liquid storage box 552, thereby increasing the fertilization range of water and fertilizer, and ensuring sufficient nutrient supply to the fruit trees.

[0035] As an embodiment of the present invention, refer to Figure 7 There are multiple liquid outlet holes 1 5521 and liquid outlet holes 2 5531. The apertures of liquid outlet holes 1 5521 are set equal, and the apertures of liquid outlet holes 2 5531 are set to increase from the liquid storage box 552 to the direction of the pin 23 connected thereto.

[0036] Under the above-mentioned setting conditions, when the movable rod 555 drives the second piston 554 to move toward the outside of the liquid outlet pipe 553, the number of the second liquid outlet holes 5531 located between the second piston 554 and the liquid storage box 552 will gradually increase, so that the water and fertilizer delivered to the inside of the liquid outlet pipe 553 can flow out from more second liquid outlet holes 5531, and fertilization can be carried out within the range between the pin 23 and the fruit tree. Since the aperture of the second liquid outlet hole 5531 is larger the farther away from the fruit tree, the root hairs at the edge of the root system of the fruit tree can absorb more nutrients, so the applied fertilizer can be increased the farther away from the fruit tree, thereby ensuring the effective absorption of fertilizer by the roots of the fruit tree.

[0037] A method for using the water-fertilizer system suitable for any of the above-mentioned fruit tree plantings comprises the following steps: S1, splice two mounting bases 1 in a circular shape around the fruit tree and then splice the arc-shaped tooth plate 31 outside the fruit tree; S2. Water and fertilizer are transported to the corresponding liquid storage box 552 through the two second liquid infusion tubes 556. The water and fertilizer naturally flow out through the first liquid outlet 5521 and the second liquid outlet 5531 to the vicinity of the fruit tree root system. S3. Start the motor 4. The motor 4 drives the arc-shaped toothed plate 31 to rotate via the gear 41. The motor 4 drives the pressing plate 33 to rotate and squeeze the stopper 24 by utilizing the connection between the driving plate 32 and the pressing plate 33. When the stopper 24 is squeezed, the sleeve 22 is driven to move along the axial direction and squeeze the piston 1 25 via the spring 2 27, so that the pin 23 pierces the soil along the axial direction and transports water and fertilizer. S4. During the growth of the fruit tree, the electric push rod 6 is activated. The output end of the electric push rod 6 drives the second arc plate 51 downward, and utilizes the hinged action of the hinged rod 52 and the limiting action of the limiting member 55 to drive the slider 53 away from the fruit tree. When the slider 53 moves away from the fruit tree, it drives the pin 23 to move upward and increase the exposed area of the second liquid outlet hole 5531. S5, start the motor 4 again, repeat the soil-piercing and water and fertilizer delivery work, and realize large-scale fertilization of the fruit tree root system.

[0038] Specifically, after the entire device is assembled around the fruit trees, two second infusion tubes 556 are used to deliver water and fertilizer to the corresponding liquid storage boxes 552. In the early stages of fruit tree cultivation, when the fruit trees have fewer roots and a smaller distribution range, water and fertilizer can drip through the first and second liquid outlet holes 5521 and 5531 and land near the center of the fruit trees. When water and fertilizer need to be applied from inside the soil, the motor 4 is started, and the output end of the motor 4 drives the gear 41 to rotate. Since the two arc-shaped tooth plates 31 are spliced into a ring shape, the gear 41 can drive the arc-shaped tooth plate 31 to rotate on the guide rail 13 through meshing action when it rotates. During the rotation of the arc-shaped tooth plate 31, the driving plate 32 is driven to rotate. Since a plurality of pressure plates 33 are arranged on the driving plate 32, the pressure plate 33 will rotate with the driving plate 32 and squeeze the block 24, and the block 24 will drive the sleeve 2 2 moves and squeezes the spring 1 26 arranged between the stopper 24 and the sliding sleeve 21. Since the sliding sleeve 21 is hingedly arranged inside the through hole 111 on the mounting plate 11, and the sleeve 22 is inserted into the sliding sleeve 21, the sliding sleeve 21 will move downward along the axis direction of the sliding sleeve 21 after being squeezed by the stopper 24. Since the pin 23 is inserted into the sleeve 22 and is connected to the piston 1 25, and a spring 27 is arranged between the piston 1 25 and the sleeve 22, the spring 27 is connected to the sleeve 22. When the sleeve 22 moves downward along the axis of the sleeve 21, it can drive the pin 23 to move synchronously. When the lower end of the pin 23 contacts the ground and is blocked, the spring 27 begins to contract, and the water and fertilizer stored in the sleeve 22 can be pressed into the pin 23 through the one-way valve 251 and finally flow out to the ground through the injection hole 231 on the pin 23, thereby wetting the soil and reducing the stress and vibration of the pin 23 when it pierces the soil. Since the motor 4 continues to work, when the pressure plate 33 After rotating until it is misaligned with the stopper 24, spring 1 26 and spring 2 27 drive the sleeve 22 and the pin 23 to reset respectively. During the resetting process, the pin 23 drives the piston 1 25 to move toward the outside of the sleeve 22 along the axis of the sleeve 22, and the water and fertilizer can be sucked into the internal storage of the sleeve 22 by the infusion tube 1 28 through the one-way valve 1 281. As the motor 4 continues to work, the stopper 24 will be re-squeezed by another pressure block, thereby driving the pin 23 to perform multiple ground-breaking operations; When the roots of the fruit trees grow rapidly in all directions in spring and summer, the electric push rod 6 is started, and the output end of the electric push rod 6 drives the arc plate 2 51 to move downward. During the downward movement of the arc plate 2 51, the upper end of the hinged rod 52 is driven to move downward. Since the liquid storage box 552 is set on the arc plate 12 through the fixed rod 551, and the liquid outlet pipe 553 is set on the liquid storage box 552, the liquid outlet pipe 553 and the arc plate 12 are in a relatively static state, the upper end of the hinged rod 52 can drive the U-shaped plate 54 to move during the downward movement, and the movable rod 555 can be driven to move during the movement of the U-shaped plate 54. Since the movable rod 555 is sleeved with the liquid outlet pipe 553, the U-shaped plate 54 can be limited so that the U-shaped plate 54 can only move away from the fruit tree in the horizontal direction. On the one hand, since the hinged rod 52 is connected to the slider 53 and slides The block 53 is sleeved with the pin 23, and the U-shaped plate 54 can drive the pin 23 to move upward and away from the fruit tree in the process of moving away from the fruit tree, thereby increasing the distance between the pin 23 and the ground, thereby reducing the depth of the pin 23 into the soil when the bottom of the pressure plate 33 contacts the block 24, avoiding the pin 23 from piercing the root system of the fruit tree, and further ensuring the normal growth of the fruit tree; on the other hand, since the movable rod 555 is provided with a piston 2 554, the movable rod 555 can increase the number of liquid outlet holes 2 5531 located between the piston 2 554 and the fruit tree in the process of moving toward the outside of the liquid outlet pipe 553, thereby expanding the fertilization range of the dripping water and fertilizer, and the fertilization amount gradually increases from the center of the fruit tree root system to the surrounding area, ensuring that the root hairs at the edge of the fruit tree root system can fully absorb the nutrients in the water and fertilizer, thereby ensuring the normal growth of the fruit tree.
