Description

Technical Field

[0001] The present invention relates to the technical field of irrigation for planting, and in particular to an irrigation device for litchi planting. Background Art

[0002] The manufacturing of mechanized agricultural and horticultural machinery, such as intelligent agricultural power machinery, is continuously injecting efficiency and precision into agricultural production. The research and development and production of these machines cover multiple links of agricultural planting, from early preparation to later management, and are driving the transformation of traditional agriculture towards modernization and intelligence. During the lychee tree planting process, irrigation has a direct impact on the growth status and fruit quality of the lychee. In order to meet the water needs of the lychee tree at different growth stages, the lychee tree root system needs to be irrigated regularly. In addition, during the hot and dry period, to ensure the metabolism and growth stability of the lychee tree at this stage, people usually carry out auxiliary watering (mainly spraying) on ​​the lychee tree crown during this period to improve the growth stability of the lychee tree during this period. However, most of the existing irrigation devices have a single function and are difficult to coordinate water supply. For example, the existing traditional drip irrigation and flood irrigation devices usually only irrigate the root area, and the spray device is mostly used alone for the crown, which cannot achieve the simultaneous operation of precise root watering and crown auxiliary humidification. At the same time, the existing root irrigation devices and crown irrigation devices are usually unable to adjust the irrigation radius according to the age of the litchi tree (for example, the root diameter and crown width of young trees and adult trees are quite different), which reduces the effect of the device on watering continuously growing litchi trees. To this end, we propose an irrigation device for litchi planting to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems raised in the background technology and to propose a watering device for litchi planting.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A litchi planting irrigation device includes a water supply pipe and two mounting bases. The water supply pipe is fixedly connected to two water delivery pipes. A water collecting cylinder is fixedly mounted on each of the mounting bases, and one end of each of the two water delivery pipes is sealed and fixedly mounted on the corresponding water collecting cylinder. A cylinder is fixedly mounted on each of the mounting bases, and both cylinders are fixedly connected to one end of the corresponding water delivery pipe. A drive assembly is provided in each of the cylinders for adjusting the irrigation range as required. The two drive assemblies each include a rotating shaft, and the rotating shaft seal passes through and is rotatably mounted on the corresponding cylinder. A driving plate 1 is fixedly mounted on the two rotating shafts, a driving plate 2 is fixedly mounted on the two rotating shafts, and a limiting mechanism is installed in the two cylinders. The two water collecting cylinders are both sealed and rotatably mounted with telescopic tubes, the fixed ends of the two telescopic tubes are both fixedly connected with regulating tubes, one end of the two regulating tubes is both fixedly connected with a flat-mouth nozzle, and the telescopic ends of the two telescopic tubes are both fixedly connected with an atomizing nozzle.

[0005] Compared with the existing technology, the advantages of the present invention are: 1: When watering the roots and crowns of litchi trees, the present invention cooperates with the blocking component and the two flat-mouth nozzles and the atomizing nozzle to water the roots and crowns of litchi trees separately as needed, thereby helping to improve the overall watering effect of the device on litchi trees and increase the wide applicability of the device.

[0006] 2: Before watering the roots or crowns of litchi trees, the present invention can first adaptively adjust the forced rotating spray arcs of the two flat-mouthed nozzles and the two atomizing nozzles according to the root diameter or crown width of the litchi trees through the cooperation of the driving component and the adjusting component. This can help improve the effect of the device on watering the roots and crowns of continuously growing litchi trees. At the same time, through the telescopic tube and the adjusting tube, the adaptability of the flat-mouthed nozzles to the roots of the litchi trees, and the adaptability of the atomizing nozzles to the crowns can be further improved according to the height of the litchi tree crowns and the root diameter. This can help further improve the adaptability of the device to watering continuously growing litchi trees and improve the watering effect of the device on continuously growing litchi trees.

[0009] 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.

[0010] Reference Figures 1-17 A watering device for litchi planting includes a water supply pipe 1 and two mounting seats 4. Two water pipes 3 are fixedly connected to the water supply pipe 1. Water collecting cylinders 5 are fixedly installed on the two mounting seats 4, and one end of the two water pipes 3 is sealed and fixedly installed on the corresponding water collecting cylinders 5. A cylinder 7 is fixedly installed on the two mounting seats 4, and the two cylinders 7 are fixedly connected to one end of the corresponding water pipe 3. A driving assembly 8 is provided in the two cylinders 7 for adjusting the irrigation range as required.

[0011] A telescopic tube 6 is sealed and rotatably installed on both water collecting cylinders 5. The fixed ends of the two telescopic tubes 6 are fixedly connected to an adjusting tube 11. One end of the two adjusting tubes 11 is fixedly connected to a flat-mouth nozzle 12. The telescopic ends of the two telescopic tubes 6 are fixedly connected to an atomizing nozzle 13.

[0012] During the growth process of litchi trees, in order to meet the physiological needs of tree growth, new shoot germination, fruit development, etc., the roots of litchi trees need to be watered regularly. In addition, in order to reduce the impact of high temperature or drought on the growth of litchi trees and ensure the stability of the metabolism and growth of litchi trees at this stage, people usually carry out auxiliary watering (mainly spraying) on ​​the crown of litchi trees during high temperature and drought periods to reduce the temperature of leaves and tender shoots through water evaporation, and avoid wilting or sunburn caused by excessive transpiration. In addition, during the period when new shoots of litchi trees sprout and leaves stretch, watering the crown can also help alleviate the inhibition of new shoot germination and leaf expansion caused by the dry environment, create a suitable microenvironment for the growth of young organs, and help improve the stability of litchi tree growth ("crown" refers to the whole part of the tree consisting of all branches and leaves growing from the main trunk upward).

[0013] However, most existing irrigation devices have a single function and are difficult to coordinate water supply. For example, existing traditional drip irrigation and flood irrigation devices are usually only used for the root area, while spray devices are mostly used alone for the crown, which cannot meet the needs of watering both the roots and the crown of the lychee tree at the same time.

[0014] In addition, existing root watering devices and crown watering devices usually have the problem of fixed range. They cannot adjust the watering radius according to the age of the lychee tree (for example, the root diameter of young trees and adult trees is quite different), and cannot provide adaptive watering for the roots of lychee trees. In addition, the crown spray devices mostly have fixed heights and spray angles, which are difficult to adapt to trees with different crown sizes, reducing the watering effect of the device on the crown of the lychee tree.

[0015] In the present invention, through the cooperation of the two adjusting tubes 11, the flat nozzle 12, the atomizing nozzle 13 and the blocking component 10, the roots and the crown of the litchi tree can be watered separately as needed, which can help improve the watering effect of the device on the litchi tree and improve the stability of the litchi tree growth. At the same time, through the cooperation of the driving component 8 and the adjusting component 9, the watering radius of the roots and the crown of the litchi tree of the device can be adjusted according to the age of the litchi tree, which can help improve the adaptability of the device to the watering of continuously growing litchi trees.

[0016] Reference Figure 2-13 、 Figure 15 , an adjustment assembly 9 is provided in each of the two cylinders 7, and each of the two adjustment assemblies 9 includes a rotating rod 92, and the rotating rod 92 is rotatably mounted on the inner wall of the corresponding cylinder 7, and two sealing plates 91 are sealed and slidably mounted on the two sealing disks 815, and a rod body is fixedly mounted on the sealing plate 91 (drawn in the figure but not marked, combined with Figure 12 and Figure 13 As can be seen, two adjustment plates 93 are fixedly mounted on the two rotating rods 92, and the adjustment plates 93 are matched with the corresponding rod bodies, and an adjustment mechanism is installed between the two rotating rods 92 and the corresponding rotating shafts 81.

[0017] The two drive assemblies 8 each include a rotating shaft 81, and the rotating shaft 81 is sealed and rotatably installed on the corresponding cylinder 7. A driving plate 1 83 is fixedly installed on the two rotating shafts 81, and a driving plate 2 84 is fixedly installed on the two rotating shafts 81. The two driving plates 1 83 and the two driving plates 2 84 are both sealed and slidably installed between the corresponding sealing disk 815 and the lower wall inside the cylinder 7, and a limiting mechanism is installed in the two cylinders 7.

[0018] The two limiting mechanisms each include a sealing disk 815, and the sealing disk 815 is fixedly mounted on the inner wall of the corresponding cylinder 7, and the two rotating shafts 81 are sealed and penetrated and rotatably mounted on the corresponding sealing disk 815, and the two sealing disks 815 are fixedly mounted with an elastic membrane 1, and the two elastic membranes 1 are sealed and penetrated and fixedly mounted with a connecting rod 86, and one end of the two connecting rods 86 is fixedly mounted with a limiting plate 1 87, and the two limiting plates 1 87 are sealed and slidably mounted between the corresponding cylinder 7 and the sealing disk 815, and a clamping component is installed between the two limiting plates 1 87 and the corresponding driving plate 1 83, and the two elastic membranes 1 are sealed and penetrated and fixedly mounted with a rack plate 89, and one end of the two rack plates 89 is fixedly mounted with a limiting plate 2 88, and the two limiting plates 2 88 are sealed and slidably mounted on the corresponding limiting plate 1 87 (from Figure 7As can be seen in the figure, both driving plates 84 are provided with square openings that cooperate with the corresponding limit plates 88 and rack plates 89. The purpose is to facilitate rotational displacement along the arc of the corresponding limit plates 88 and rack plates 89 when the subsequent driving plates 84 are rotated under force). Driving components are installed on both cylinders 7.

[0019] Combine Figure 6 and Figure 10 As shown, in the initial state, the distance between the two adjacent limit plates 1 87 and the limit plate 2 88 close to each other at one end is the minimum arc of rotation of the corresponding driving plate 1 83 under force, that is, the driving plate 1 83 is forced to drive the corresponding flat nozzle 12 and the atomizing nozzle 13 to rotate through the cooperation of the corresponding rotating shaft 81 and the telescopic tube 6. At this stage, the device is suitable for watering litchi trees with smaller root and crown diameters.

[0020] At this stage, when the device is needed to irrigate the roots or crowns of litchi trees, water can be first supplied to the two water pipes 3 through the cooperation of the existing water supply device and the water supply pipe 1. When the water flowing in the water pipe 3 enters the corresponding cylinder 7, the upper sealing plate 91 inside the cylinder 7 is in a larger opening (combined with the Figure 10 and Figure 11 It can be seen that in the initial state, the opening of the lower blocking plate 91 is much smaller than the opening of the corresponding upper blocking plate 91. At the same time, the "opening" referred to here refers to the distance between the lower end of the blocking plate 91 and the bottom wall of the corresponding cylinder 7. Therefore, most of the flowing water entering the cylinder 7 at this time will flow in the cylinder 7 in a clockwise direction (such as Figure 10 In this process, the impact force of the water on the corresponding driving plate 1 83 can drive the driving plate 1 83 to drive the corresponding rotating shaft 81 and the driving plate 2 84 to rotate clockwise.

[0021] When the driving plate 1 83 drives the corresponding rotating shaft 81 to rotate, the corresponding telescopic tube 6, flat nozzle 12, and atomizing nozzle 13 can be rotated clockwise together through the cooperation between the rotating shaft 81 and the corresponding driving disk 82 (as shown in FIG. Figure 15 In the direction shown), the device can rotate to spray and irrigate the roots or crowns of the litchi trees, and through the relative two flat-mouth nozzles 12 and the atomizing nozzle 13, it can help to improve the uniformity of the overall watering of the roots or crowns of the litchi trees, thereby improving the watering effect of the device on the litchi trees.

[0022] Reference Figure 2-Figure 10 The two engaging parts each include a placement slot, and the placement slot is opened on the corresponding limit plate 87. The two driving plates 83 are fixedly mounted with an engaging block 811, and the two placement slots are fixedly mounted with two elastic clips 812.

[0023] The two driving components each include a shaft, and the shaft is rotatably mounted on the top wall of the corresponding cylinder 7. The two shafts are fixedly mounted with a rotating gear 810 that meshes with the corresponding rack plate 89. The two cylinders 7 and the two water collecting cylinders 5 are fixedly mounted with an elastic membrane 2 (drawn in the figure but not marked from Figure 9 As can be seen in the figure), an arc-shaped driving member 85 is sealed and fixedly installed between the two corresponding elastic membranes 2, and the two arc-shaped driving members 85 are fixedly connected to the corresponding connecting rods 86. The two arc-shaped driving members 85 are fixedly installed with tooth blocks that are evenly distributed in an arc shape, and the tooth blocks are matched with the corresponding rotating gears 810. The two water collecting cylinders 5 are provided with positioning holes 813 that are evenly distributed in an arc shape. The two arc-shaped driving members 85 are penetrated and slidably installed with positioning rods 814 that match the corresponding positioning holes 813. The two cylinders 7 are provided with infusion ports that are evenly distributed in an arc shape (drawn in the figure but not marked from, from Figure 10 can be seen).

[0024] Combine Figure 5 and Figure 6 It can be seen that the two arc-shaped driving members 85 are composed of an arc-shaped plate, a straight plate and a round roller. The two straight plates are sealed and fixedly installed between the corresponding two elastic membranes 2. The two arc-shaped plates are fixedly connected to the corresponding straight plates, and the corresponding multiple tooth blocks are fixedly installed on the corresponding arc-shaped plates. The two round rollers are fixedly installed on the corresponding straight plates, and the two positioning rods 814 are penetrated and slidably installed on the corresponding round rollers.

[0025] As the litchi tree continues to grow, if the irrigation range of the device needs to be increased according to the increase in the diameter of the main root of the litchi tree or the expansion of the crown width before using the device, the positioning rod 814 is first pulled out from the corresponding positioning hole 813, and then the arc-shaped driving member 85 is manually driven to rotate counterclockwise (such as Figure 6 In the direction shown), during the process in which the arc-shaped driving member 85 drives the corresponding limit plate 1 87 and multiple gear blocks to rotate counterclockwise, the corresponding multiple gear blocks cooperate with the corresponding rotating gear 810 and the corresponding rotating gear 810 to drive the corresponding rack plate 89 to drive the corresponding limit plate 2 88 to rotate clockwise, thereby gradually increasing the distance between the corresponding limit plate 1 87 and the limit plate 2 88 close to one end, that is, increasing the force that the corresponding driving plate 1 83 can bear to drive the corresponding flat nozzle nozzle 12 and the atomizing nozzle 13 to rotate the spray arc.

[0026] At the same time, when the corresponding limit plate 1 87 is forced to rotate counterclockwise, the corresponding two elastic clamps 812 exert a clamping force on the corresponding clamping block 811, so that the limit plate 1 87 can drive the corresponding drive plate 1 83, the rotating shaft 81, and the drive plate 2 84 to rotate counterclockwise during the counterclockwise rotation. This can ensure that the subsequent rotating shaft 81 cooperates with the adjustment component 9, driving the telescopic tube 6 to drive the corresponding flat-mouth nozzle 12 and the atomizing nozzle 13 to rotate back and forth on the adjusted rotation arc to ensure the stability of watering the roots and crowns of the litchi trees.

[0027] After the two telescopic tubes 6 are adjusted in turn and adaptively according to the needs of watering the litchi trees, that is, after the arc of the device for watering the litchi trees is adaptively adjusted, the two positioning rods 814 are inserted into the corresponding positioning holes 813 in turn, so as to fix the positions of the corresponding limit plates 1 87 and 2 88, which helps to improve the watering range of the device through the drive assembly 8. After the device is adjusted, the device can maintain a stable watering arc to water the roots and crowns of the litchi trees.

[0028] like Figure 8 As shown, multiple elastic clamps 812 are provided, each consisting of a spring telescopic rod and a clamping roller. The multiple spring telescopic rods are fixedly mounted on the corresponding placement slots, and the multiple clamping rollers are fixedly mounted on the corresponding elastic telescopic rods. Before watering the litchi tree, the watering arc needs to be adjusted according to the size or growth of the litchi tree. When the limit plate 87 rotates counterclockwise (as shown in FIG. Figure 6 The cam 812 is pressed against the bottom of the cam 814 so that the cam 814 can be moved out of the way when the cam 814 is in the process of rotation.

[0029] Reference Figure 3-Figure 14 Both adjustment mechanisms include a parallel axis gear 94, and the parallel axis gear 94 is fixedly mounted on the corresponding rotating shaft 81. Guide rods are fixedly mounted on the inner walls of the two cylinders 7, and racks 95 meshing with the corresponding parallel axis gears 94 are slidably mounted on the two guide rods. Push components are installed on both racks 95.

[0030] Each of the two pushing components includes a pushing plate 96, and the pushing plate 96 is fixedly mounted on the corresponding rack 95. Both racks 95 are provided with a sliding groove, and both sliding grooves are slidably mounted with sliding rods. Both sliding rods are fixedly mounted with a pushing plate 98, and both sliding rods are fixedly mounted with a limiting rod 910. Both rotating rods 92 are fixedly mounted with a plate body 97, and both rotating rods 92 are fixedly mounted with a plate body 2 99.

[0031] Combine Figure 10 and Figure 12 As shown in the direction, when the water starts to be delivered to the inside of the cylinder 7, the impact force of the water flow drives the corresponding drive plate 83, the rotating shaft 81 and the parallel axis gear 94 to rotate clockwise (as shown in FIG. Figure 12 As shown in the direction, the driving force applied by the parallel shaft gear 94 to the corresponding rack 95 can drive the corresponding rack 95 to drive the corresponding push plate 1 96, push plate 2 98 and limit rod 910 upward, that is, Figure 14 In the direction shown, move to the left, and when the push plate 1 96 is in contact with the corresponding plate body 1 97 and is continuously moved to the left by the force (that is, the driving plate 1 83 is not in contact with the corresponding limit plate 2 88 at this time), the driving force applied by the push plate 1 96 to the corresponding plate body 1 97 can drive the corresponding plate body 1 97, the plate body 2 99, and the rotating rod 92 to rotate counterclockwise with the center point of the rotating rod 92 as the axis (combined with the Figure 13 and Figure 14 direction shown).

[0032] When the rotating rod 92 is rotated counterclockwise by the force and drives the corresponding two adjustment plates 93 to rotate together, the driving force applied to the corresponding rod body through the driving openings opened on the corresponding two adjustment plates 93 can drive the left blocking plate 91 to gradually move downward and the right blocking plate 91 to gradually move upward (such as Figure 13 1 and 1 are rotated to the top of the corresponding rotating rod 92 (and it is arranged that when the driving plate 83 drives the corresponding rack 95 and the push plate 1 96 to stop moving, the push plate 1 96 is still located on the right side of the corresponding plate body 1 97, so that when the push plate 1 96 is forced to move and reset, it will not drive the corresponding plate body 1 97 and the rotating rod 92 to rotate and displace).

[0033] At the same time, when the driving plate 83 stops moving, the opening of the upper blocking plate 91 is much smaller than the opening of the corresponding lower blocking plate 91 (such as Figure 10 As shown in the direction, it can be ensured that most of the water that enters the cylinder 7 can flow to the side where the corresponding drive plate 2 84 is located. When the impact force of the water flow on the corresponding drive plate 2 84 increases, the corresponding drive plate 2 84, the rotating shaft 81, and the drive plate 1 83 can be driven by the water flow to rotate counterclockwise and reset.

[0034] When the driving plate 2 84 is driven by the force to drive the corresponding rotating shaft 81 to rotate and reset, the reaction force exerted by the parallel shaft gear 94 on the corresponding rack 95 can drive the rack 95 to drive the corresponding push plate 2 98 and the push plate 1 96 to move to the right and reset (as shown in FIG. Figure 14 In the direction shown), during this process, when the push plate 2 98 is in contact with the corresponding plate body 2 99 and continues to move to the right, the driving force applied by the push plate 2 98 to the corresponding plate body 2 99 can drive the plate body 2 99 to drive the corresponding rotating rod 92 and plate body 1 97 to rotate and reset until the driving plate 1 83 is re-fitted with one end of the corresponding limit plate 1 87, and the rotating rod 92 adjusts the openings of the corresponding two blocking plates 91 to the initial size by cooperating with the corresponding two adjustment plates 93 and the two rod bodies.

[0035] When the openings of the two blocking plates 91 are adjusted to their initial sizes, that is, the opening of the upper blocking plate 91 is much larger than the opening of the corresponding lower blocking plate 91 (e.g. Figure 10 In the direction shown), at this time, the impact force generated by the water flow on the corresponding driving plate 1 83 can repeatedly drive the corresponding driving plate 1 83, the rotating shaft 81, the driving plate 2 84, and the telescopic tube 6 to rotate clockwise. Then, the above operation is repeated to achieve the effect of reciprocating spraying on the roots or crowns of the litchi trees, which helps to further improve the effect and uniformity of the device in watering the roots and crowns of the litchi trees.

[0036] At the same time, before watering the roots or crowns of the litchi trees, the watering arc of the device is adaptively adjusted by the above-mentioned driving assembly 8, and the limiting plate 1 87 is driven by the corresponding driving plate 1 83 and the rotating shaft 81 to rotate counterclockwise (such as Figure 12 In the direction shown), at this time, the driving force applied to the corresponding rack 95 by the rotation shaft 81 cooperates with the corresponding parallel axis gear 94, which can drive the corresponding push plate 1 96 to move to the right, gradually away from the corresponding plate body 1 97 (combined with Figure 13 and Figure 14 In the direction shown), the time required for the push plate 1 96 to drive the corresponding rotating rod 92 to rotate can be adaptively increased while the arc of the device for watering the litchi tree is increased, that is, the stability of the arc of the device for watering the litchi tree is ensured. For example, when the distance between the corresponding limiting plate 1 87 and the limiting plate 2 88 increases, the arc of rotation of the rotating shaft 81 and the telescopic tube 6 driven by the corresponding driving plate 1 83 increases, and the rotation time increases. At this time, by adaptively increasing the time required for the push plate 1 96 to drive the rotating rod 92 to rotate, it can be ensured that the driving plate 1 83 is forced to drive the corresponding telescopic tube 6 to rotate to the required arc before the adjusting component 9 is used to drive the telescopic tube 6 to rotate and reset.

[0037] When the shaft 81 rotates counterclockwise, the corresponding rack 95 is driven to move to the right (combined with Figure 13 and Figure 14In the direction shown), at this time, the movement of the limit rod 910 is limited by the corresponding rotating rod 92, that is, the rotating rod 92 cooperates with the sliding rod through the corresponding limit rod 910 to indirectly limit the movement of the corresponding push plate 2 98, so that the sliding rod can drive the corresponding push plate 2 98 to move to the left, and gradually increase the distance between it and the corresponding push plate 1 96. This can further ensure that when the device increases the watering arc of the litchi tree and increases the time required for the push plate 1 96 to drive the corresponding rotating rod 92 to rotate, the push plate 2 98 is adaptively increased by cooperating with the corresponding plate body 2 99 to drive the corresponding rotating rod 92 to rotate and reset. This can further ensure that the device can maintain the stability of the new reciprocating watering arc when increasing the watering arc of the litchi tree and reciprocatingly watering the roots and crowns of the litchi tree.

[0038] Reference Figure 15-17 A blocking assembly 10 is provided in each of the two telescopic tubes 6. The two blocking assemblies 10 each include a driving disk 82, and the driving disk 82 is fixedly mounted on the corresponding rotating shaft 81, and the driving disk 82 is fixedly connected to the inner wall of the corresponding telescopic tube 6. A blocking piece 101 is placed on each of the two driving disks 82, and the two blocking pieces 101 are slidably mounted on the inner wall of the corresponding telescopic tube 6. Two round rods 102 are fixedly mounted on the two blocking pieces 101, and a guide rod 104 is fixedly mounted on the inner top wall of the telescopic end of the two telescopic tubes 6. A floating plate 103 is slidably mounted on the two guide rods 104, and the two floating plates 103 are slidably mounted on the corresponding two round rods 102. A booster pump 2 is installed on the water supply pipe 1.

[0039] After the above-mentioned water flow enters the interior of the cylinder 7, the water flow gathered in the interior of the cylinder 7 will gradually flow into the water collecting cylinder 5 from the corresponding multiple infusion ports, and enter the corresponding telescopic tube 6 along the water collecting cylinder 5. If the device needs to be used to water the roots of the litchi tree at this time, the booster pump 2 can be started and the booster pump 2 can be adjusted to a low-pressure output state to ensure that the liquid entering the telescopic tube 6 rises slowly and always remains below the atomizing nozzle 13. Since the flow rate of the water entering the telescopic tube 6 at this time is slow and the pressure is low, the liquid level cannot reach the position of the corresponding atomizing nozzle 13. Therefore, the water entering the telescopic tube 6 at this time will all follow the corresponding regulating tube 11 and be sprayed toward the roots of the litchi tree by the corresponding flat-mouth nozzle 12, thereby achieving precise watering of the roots of the litchi tree.

[0040] The driving assembly 8 and the adjusting assembly 9 arranged inside the two cylinders 7 are both made of lightweight materials. The purpose is to ensure that when the device is used to irrigate the roots of the litchi tree, the water flows into the cylinder 7 at a relatively slow speed. At this time, the impact force generated by the water flow can still cooperate with the driving assembly 8 and the adjusting assembly 9 to drive the telescopic tube 6 to drive the corresponding flat-mouth nozzle 12 and the atomizing nozzle 13 to rotate and irrigate the roots of the litchi tree.

[0041] At the same time, because the crown of the litchi tree is composed of branches at all levels above the trunk (from main branches, side branches to twigs), all leaves (outer leaves, upper leaves, lower leaves, etc.), the overall shape is mostly umbrella-shaped, round-headed or semicircular, and its diameter is usually much larger than its main root diameter. Therefore, when the two atomizing nozzles 13 are installed at a suitable distance from the crown of the litchi tree through the corresponding telescopic tubes 6 and the mounting base 4 according to the crown width of the litchi tree, the two atomizing nozzles 13 can be stretched by stretching the two adjusting tubes 11 (from Figure 11 As can be seen in the figure, both regulating tubes 11 have telescopic functions), and the two flat-mouthed nozzles 12 are brought closer to the roots of the litchi tree, so as to ensure that when the device waters the roots of the litchi tree through the two flat-mouthed nozzles 12, the water flow sprayed by the two flat-mouthed nozzles 12 has the effect of watering the roots of the litchi tree.

[0042] In addition, when the liquid inside the telescopic tube 6 flows to the right along the corresponding regulating tube 11 (as shown in FIG. Figure 17 In the direction shown), the contraction section of the regulating tube 11 can gradually increase the water flow rate and improve the kinetic energy of the water flow, which can help to increase the initial velocity of the water flow finally ejected by the flat-mouth nozzle 12. The range of the liquid (when air resistance is ignored) is mainly determined by the initial velocity of the ejection (the greater the initial velocity, the longer the range). Therefore, on the basis of compensating for the distance between the flat-mouth nozzle 12 and the roots of the lychee tree by stretching the regulating tube 11, the distance between the flat-mouth nozzle 12 and the roots can be further compensated by increasing the spraying distance of the flat-mouth nozzle 12 (such as when the crown diameter of the lychee tree and the root diameter are significantly different, and the initial positions of the two flat-mouth nozzles 12 are far from the roots). This can help to further improve the accuracy and effect of watering the roots of the lychee tree through the two flat-mouth nozzles 12.

[0043] At the same time, before the device is needed to atomize and spray the crown of the litchi tree, the length of the telescopic tube 6 can be adaptively adjusted according to the height of the litchi tree (and in this process, the floating plate 103 can be moved up together through the guide rod 104) to ensure that the two atomizing nozzles 13 are in the appropriate position of the crown of the litchi tree, such as the middle position, so as to ensure that the device cooperates with the atomizing nozzle 13 through the two drive components 8 to uniformly irrigate the entire crown of the litchi tree, thereby improving the effect of the device in atomizing and spraying the crown of the litchi tree.

[0044] After the heights of the two atomizing nozzles 13 are adjusted, the output pressure of the booster pump can be increased first to increase the speed of the water entering the telescopic tube 6. When the liquid level inside the telescopic tube 6 rises rapidly and reaches the height of the atomizing nozzle 13, the liquid can be sprayed out through the atomizing nozzle 13 to start atomizing spraying treatment on the crown of the litchi tree.

[0045] At the same time, when the liquid level inside the telescopic tube 6 rises rapidly, the liquid level reaches the lower end of the corresponding floating plate 103 and moves upward rapidly (combined with Figure 15 and Figure 16As shown in the direction), at this time, under the action of the buoyancy of the water body and the impact force generated by the water flow, the corresponding floating plate 103 can be driven to move upward along the corresponding two round rods 102 and the guide rod 104. When the floating plate 103 moves to the top of the two round rods 102, that is, the lower end of the circular plate set at the upper ends of the two round rods 102, and the buoyancy and impact force generated by the water flow on it continue to drive the floating plate 103 to move upward, the floating plate 103 can apply an upward driving force to the top of the two round rods 102 to drive the corresponding two round rods 102 and the blocking member 101 to move upward together until the plate set on the side of the blocking member 101 is The body blocks the water inlet end of the corresponding regulating pipe 11, thereby effectively ensuring that when the device needs to be used to atomize and spray the litchi tree crown, only the two atomizing nozzles 13 spray water, that is, ensuring the stability and spraying effect of the two atomizing nozzles 13 in atomizing and spraying the litchi tree crown at this stage (if at this stage, part of the liquid inside the telescopic tube 6 is sprayed out by the corresponding flat-mouth nozzle 12, it is easy to cause the flow rate and water pressure of the water sprayed by the corresponding atomizing nozzle 13 to fail to achieve the expected effect, which not only easily reduces the atomizing and spraying effect on the litchi tree crown, but also easily reduces the accuracy of its spraying).

[0046] In addition, in order to further ensure the effect of the device in atomizing and spraying the crown of the litchi tree through the cooperation of the two relative atomizing nozzles 13, a baffle can be added to the inner wall of the two telescopic tubes 6 and above the water inlet ends of the two regulating tubes 11. The baffle can be used to limit the movement of the corresponding blocking member 101. For example, when the corresponding blocking member 101 moves up to block the water inlet of the corresponding regulating tube 11, and the liquid level inside the telescopic tube 6 reaches the height of the corresponding atomizing nozzle 13, the baffle can limit the movement of the upper end side plate of the corresponding blocking member 101, thereby ensuring the blocking effect of the blocking member 101 on the water inlet of the corresponding regulating tube 11 at this stage, that is, further ensuring the effect of the device in atomizing and spraying the crown of the litchi tree at this stage.

[0047] At the same time, the two atomizing nozzles 13 can specifically use fan-shaped diffusion pressure adaptive nozzles. The outlet of this type of atomizing nozzle 13 is a thin-sheet fan-shaped flow channel (such as a flat slit with a width of 0.1 to 0.5 mm), and the edge of the flow channel is designed to be an "elastic lip" (slightly deformed with water pressure). The influence of water pressure on the spray "angle" can be used to adjust the area. For example, when the overall height of the lychee tree crown is relatively small, the pump 2 can be increased to a lower output pressure state. At this time, the flow rate of the liquid entering the corresponding atomizing nozzle 13 through the telescopic tube 6 is relatively low, the deformation of the elastic lip at the end of the atomizing nozzle 13 is small, and the spray The spread angle is small (such as 20°), and the atomization is narrow fan-shaped with a small area. That is, the height of the liquid sprayed out by the atomizing nozzle 13 is relatively small, which is suitable for lychee trees with a smaller overall crown height. When the overall crown height of the lychee tree needs to be larger, the output pressure of the booster pump 2 can be increased to increase the flow rate of the liquid entering the corresponding atomizing nozzle 13. At this time, the impact force of the liquid on the lip is increased, and the lip is "blown open", so that the spread angle is expanded (such as 45°). At the same time, the fan surface is enlarged after atomization, that is, the fan surface of the liquid sprayed out by the atomizing nozzle 13 is larger, which is suitable for lychee trees with a larger overall crown height.

[0048] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0049] In the present invention, before using the device to water the roots or crowns of litchi trees, the two telescopic tubes 6 can be adjusted to a rotational arc that can be driven by force to drive the corresponding flat-mouthed nozzles 12 and the atomizing nozzles 13 according to the diameter of the roots or the width of the crowns of the litchi trees. After the limit plate 1 87 is driven by force to drive the corresponding flat-mouthed nozzles 12 and the atomizing nozzles 13 to rotate around the arc through the driving component 8, water can be supplied to the inside of the two cylinders 7 through the cooperation of the existing water supply device, the water supply pipe 1, and the two water pipes 3. At the same time, in this process, through the cooperation of the adjusting component 9, the driving plate 1 83, and the driving plate 2 84, the telescopic tube 6 can drive the corresponding flat-mouthed nozzles 12 and the atomizing nozzles 13 to rotate back and forth on the adjusted rotational arc to water the roots or crowns of the litchi trees. This can help improve the watering effect of the device on the roots and crowns of the litchi trees and improve the growth stability of the litchi trees.

[0050] At the same time, if the device is needed to irrigate the roots of the lychee tree, the booster pump 2 is started and adjusted to a low-pressure output state. At this time, due to the cooperation between the existing liquid supply device, the cylinder 7, and the water collecting cylinder 5, the liquid entering the telescopic tube 6 rises slowly, so that the liquid can be sprayed to the roots of the lychee tree through the corresponding flat-mouth nozzle 12, thereby achieving precise watering of the roots of the lychee tree. If the device is needed to irrigate the crown of the lychee tree, by increasing the output pressure of the booster pump 2, the effect of adaptively increasing the rising speed of the liquid inside the telescopic tube 6 can be achieved. When the liquid level in the telescopic tube 6 quickly rises to the height of the atomizing nozzle 13, by cooperating with the blocking component 10, it can be ensured that at this stage, the liquid inside the telescopic tube 6 is sprayed out through the atomizing nozzle 13, and the crown of the lychee tree is accurately atomized and sprayed.
