Description

Technical Field

[0001] This invention relates to the technical field of water-saving irrigation devices for fruit trees, and in particular to a water-saving irrigation device for fruit trees. Background Technology

[0002] Fruit tree irrigation devices refer to equipment or systems specifically designed to provide water and nutrients to fruit trees. These devices combine modern agricultural technology and engineering principles to efficiently and accurately meet the water and nutrient needs of fruit trees during their growth process, thereby promoting healthy growth and increasing yield.

[0003] When using an irrigation cart to irrigate fruit trees in an orchard, the usual method is to place buckets of water on the cart, then start the water pump to draw the water from the buckets into a hose, and then spray the water onto the fruit trees in the orchard through the hose. This method results in a wide irrigation area, and the water may be absorbed by other weeds. It is not possible to accurately irrigate the required areas, which may cause some fruit trees to wither due to insufficient water supply, thus reducing the utilization of water resources. Summary of the Invention

[0004] This invention addresses the problem of water-saving irrigation devices for fruit trees in orchards. Traditionally, when using an irrigation cart to irrigate fruit trees, a water-filled bucket is placed on the cart, a water pump is activated to draw water into a hose, and then the hose is used to spray water onto the trees. This method results in a wide irrigation area, where water may be absorbed by weeds, making it difficult to precisely irrigate the desired locations. Consequently, some fruit trees may wither due to insufficient water supply, thus reducing water resource utilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water-saving irrigation device for fruit trees, comprising an irrigation cart, a fixed-point irrigation device on one side of the irrigation cart, the fixed-point irrigation device comprising a water bucket, a hose and two first belts, a stirring device inside the water bucket, the fixed-point irrigation device can transport the hose to the root position of the fruit tree to be irrigated, and then inject water into the root position of the fruit tree, so that the fruit tree can absorb water and improve the full utilization of irrigation water resources, thereby achieving the effect of saving water resources, the stirring device can stir the solid granular fertilizer put into the irrigation water, so that it can be fully mixed with the irrigation water and dissolved, and at the same time, it can crush the solid particles that sink to the bottom of the water bucket to improve the dissolution efficiency, and cooperate with the fixed-point irrigation device for fertilization treatment.

[0006] The effects achieved by the above components are as follows: When using an irrigation cart to irrigate fruit trees in an orchard, the irrigation cart can be pushed to the side of the fruit tree that needs to be irrigated. Then, the fixed-point irrigation device can be activated to transport the hose to the root position of the fruit tree that needs to be irrigated. Water can then be injected into the root position of the fruit tree, making it easier for the fruit tree to absorb water and improving the full utilization of irrigation water resources, thus achieving the effect of saving water resources. If fertilization is required, after putting solid granular fertilizer into the water bucket, the stirring device can be activated to stir the solid granular fertilizer in the irrigation water, so that it can be fully mixed and dissolved with the irrigation water. At the same time, the solid granules that sink to the bottom of the water bucket can be crushed to improve the dissolution efficiency, thus cooperating with the fixed-point irrigation device for fertilization.

[0007] Preferably, the bottom of the water bucket is fixedly connected to one side of the irrigation cart. A water pump is connected through the outer surface of the bottom of the water bucket. The outlet of the water pump is fixedly connected to one end of a flexible hose. A flow guide is fixedly connected to one end of the flexible hose. A grooved frame is symmetrically fixedly connected to one side of the irrigation cart. A threaded rod is fixedly connected to the inner wall of each grooved frame. A slide is slidably connected between the inner walls of the two grooved frames. The threaded rod passes through the inner walls of both ends of the slide. A screw-hole block is symmetrically rotatably connected to one side of the slide. The screw-hole block is threadedly connected to the threaded rod. A dual-axis servo motor is fixedly connected to one side of the slide. One output end of the dual-axis servo motor is fixedly connected to a drill rod. One end of the drill rod's outer surface is threaded through and connected to one side of a slide. A drill bit is fixedly connected to one end of the drill rod. A threaded sleeve is rotatably connected to one side of the slide, and the threaded sleeve is fitted onto the outer surface of the drill rod. A groove is formed on the inner wall of the threaded sleeve, and a rotating plate is rotatably connected to the inner wall of the groove. Torsion springs are fitted onto the outer surfaces of both ends of the rotating plate, and the two ends of the torsion springs are fixedly connected to one side of the inner wall of the groove and one side of the rotating plate, respectively. A baffle is fixedly connected to the inner wall of the groove. One end of the drill rod's outer surface is fixedly connected to... A convex plate is attached, one end of which is inserted into the inner wall of the slide groove. A one-way bearing is fixedly connected to the outer surface of one end of the drill rod. The inner walls of the two ends of the first belts are respectively sleeved on the outer surfaces of the two screw-hole blocks and the one-way bearings. A first telescopic rod is symmetrically fixedly connected to one side of the slide. A screw-hole abutment cylinder is fixedly connected to one end of the first telescopic rod. A first spring is sleeved on the outer surface of the first threaded rod. The two ends of the first spring are fixedly connected to one side of the screw-hole abutment cylinder and one side of the slide, respectively. The inner wall of one end of the screw-hole abutment cylinder is threadedly connected to the outer surface of the threaded sleeve. The inner wall of the other end of the cylinder is slidably connected to the outer surface of one end of the drill rod. Several round holes are opened on the inner wall of one end of the screw hole abutting cylinder. The flow guide is set between the outer surface of the drill rod and the inner wall of the screw hole abutting cylinder. Several outlet pipes of the flow guide are fixedly connected to the inner wall of the round holes. Several sliding hole frames are fixedly connected to one side of the drill bit. A push rod is slidably connected to the inner wall of the sliding hole frame. One end of the push rod abuts against the outer surface of one end of the screw hole abutting cylinder. A support plate is fixedly connected to one end of the push rod. A second spring is fixedly connected to one side of one end of the push rod. One end of the second spring is fixedly connected to one side of the sliding hole frame.

[0008] The effect achieved by the above components is as follows: By setting up a fixed-point irrigation device, when using an irrigation cart to irrigate the fruit trees in the orchard, the irrigation cart can be pushed to the side of the fruit tree that needs irrigation. Then, the dual-axis servo motor on the slide is started, driving the drill rod and drill bit to rotate counterclockwise on the slide. At this time, the convex plate can be driven to slide circumferentially around the drill rod in the inner wall of the slide groove. When one end rotates to one side of the rotating plate, it will push the rotating plate to rotate away from the baffle, causing the torsion spring to deform. At this time, the rotating plate can no longer limit and fix the convex plate, so the rotation of the drill rod will not drive the threaded sleeve to rotate. At this time, the one-way rotation of one end of the drill rod... The inner ring of the bearing engages and is positioned relative to the outer ring. This causes the one-way bearing to rotate when the drill rod rotates counterclockwise. Driven by the two first belts, this drives the two screw-hole blocks to rotate helically on the outer surfaces of the two threaded rods. This causes the slide to slide downwards within the inner wall of the grooved frame, resulting in the rotating drill rod and drill bit moving downwards while rotating. Drilling is then performed at the locations where the fruit trees require irrigation. The hose, several push plates, and screw-hole abutment cylinders are transported to a position near the roots of the fruit trees. Once transported to a certain position, the dual-axis servo motor is activated, causing the drill rod to rotate clockwise. At this point, the inner and outer rings of the one-way bearing disengage. This prevents the first belt from rotating, thus stopping the slide from descending. The clockwise rotation of the drill rod causes the convex plate to rotate clockwise within the slide groove, with one end abutting against the side of the rotating plate away from the baffle. The other side of the rotating plate is then fixed by the baffle, thus limiting the convex plate. This allows the threaded sleeve to rotate on the slide. Then, under the limiting action of the first telescopic rod and the first spring, one end of the threaded hole abutment cylinder moves downwards along the threaded outer surface of the threaded sleeve, while the other end slides downwards along the outer surface of the drill rod, pulling the guide frame downwards via the hose. Simultaneously, one end of the threaded hole abutment cylinder... The surface will abut one end of several push rods, which will slide to one end in the inner wall of the sliding hole frame, causing the second spring to be stretched open, thereby pushing the support plate outward in the drill hole, pushing the soil in the drill hole to both ends, increasing the area of ​​the water injection hole, so that the corresponding amount of irrigation water can be injected on one side during later irrigation, improving irrigation efficiency. During irrigation, the water pump can be started to draw water from the water tank into the hose and then into the round hole through the guide frame, and finally into the drill hole, so as to carry out fixed-point irrigation of fruit trees. This can reduce the probability of water resources being absorbed by other weeds, improve irrigation effect and water resource utilization, and achieve the effect of saving water resources.

[0009] Preferably, a second telescopic rod is fixedly connected to one side of the push rod, the outer surface of the second telescopic rod is sleeved and connected to the inner wall of the second spring, and one end of the second telescopic rod is fixedly connected to one side of the sliding hole frame.

[0010] The effect achieved by the above components is that by setting the second telescopic rod, the inner wall of the second spring can be supported, making it less prone to damage during use and improving the service life of the second spring.

[0011] Preferably, a plurality of circular rollers are rotatably connected to one side of the push rod, and the circular rollers are arranged on the side of the push rod near the screw hole abutting cylinder.

[0012] The effect achieved by the above components is as follows: by setting the circular roller, the contact wear between the screw hole abutment cylinder and the push rod can be reduced, making it easier for the screw hole abutment cylinder to push the push rod, thus making the operation smoother.

[0013] Preferably, the inner walls of several outlet pipes of the flow guide are fixedly connected with several protective blocks, and the several protective blocks are made of elastic rubber.

[0014] The effect achieved by the above components is that by setting up protective blocks, the inner walls of several outlet pipes on the flow guide can be protected and blocked, making it difficult for external dust and sand to enter the interior of the flow guide and thus avoiding affecting the use of the flow guide.

[0015] Preferably, the stirring device includes a first stirring rod and a second belt. A bracket is fixedly connected to one side of one of the grooved frames, and a round shaft is rotatably connected to one side of the bracket. A limiting telescopic rod is fixedly connected to one side of the round shaft. One end of the limiting telescopic rod is fixedly connected to the other output end of the dual-axis servo motor. The inner walls of both ends of the second belt are respectively sleeved and connected to the outer surface of one end of the first stirring rod and the outer surface of the round shaft. The outer surface of one end of the first stirring rod is connected through to one side of the inner wall of the water tank. A plurality of stirring blades are fixedly connected to the outer surface of the first stirring rod. A second stirring rod is symmetrically rotatably connected to the outer surface of one end of the first stirring rod. A plurality of crushing blocks are fixedly connected to the outer surface of the second stirring rod.

[0016] The aforementioned components achieve the following effects: When fertilizing fruit trees, fertilizer granules can be added through the inlet of the bucket, followed by the addition of an appropriate amount of water. Then, one output of the dual-axis servo motor is activated, driving the limit telescopic rod and the round shaft to rotate on the support. Driven by the second belt, the first stirring rod, several stirring blades, and the second stirring rod rotate within the inner wall of the bucket, mixing the added fertilizer granules and water to ensure thorough contact and dissolution. When some fertilizer granules sink to the bottom of the bucket, the second stirring rod and several crushing blocks, while rotating on the round shaft, stir up the sunken fertilizer granules and crush them against the bottom of the bucket, accelerating the dissolution process. This, combined with subsequent targeted irrigation, improves irrigation efficiency.

[0017] Preferably, a plurality of toothed scrapers are fixedly connected to the outer surface of the second stirring rod, and the plurality of toothed scrapers and the plurality of rolling blocks are distributed in an alternating manner.

[0018] The effect achieved by the above components is as follows: by setting the scraper blade, after the crushing block crushes the fertilizer particles that have sunk to the bottom of the bucket, some fertilizer powder may adhere to the bottom of the bucket. At this time, the scraper blade can scrape off the fragments that are adhering to the bottom of the bucket, so that the crushed fertilizer powder can be quickly dissolved.

[0019] Preferably, a bevel gear is fixedly connected to one side of the second stirring rod, and a bevel gear ring block is fixedly connected to the inner wall of the water bucket, with one side of the bevel gear ring block meshing with the outer surface of the bevel gear.

[0020] The effect achieved by the above components is as follows: by setting bevel gears and bevel gear ring blocks, while the first stirring rod rotates and drives the second stirring rod to rotate in a circular motion, the bevel gears will mesh and rotate on the bevel gear ring blocks, thereby driving the second stirring rod to rotate on its own axis, driving several crushing blocks and several scraper plates to crush and scrape the fertilizer particles that have sunk to the bottom of the water bucket, so that the fertilizer can fully contact the water and dissolve, thus accelerating the dissolution speed of the fertilizer particles.

[0021] Preferably, a connecting bearing is fixedly connected to the outer surface of one end of the second stirring rod, and the outer ring of the connecting bearing is fixedly connected to the outer surface of one end of the first stirring rod.

[0022] The effect achieved by the above components is that by setting a connecting bearing, the rotational wear at the connection between the second stirring rod and the first stirring rod can be reduced, making it easier for the second stirring rod to rotate and improving the service life of both.

[0023] Preferably, a limiting ring block is symmetrically fixedly connected to one end of the outer surface of the first stirring rod, and one end of the second belt is disposed between the two limiting ring blocks.

[0024] The effect achieved by the above components is that by setting the limiting ring block, the second belt on the first stirring rod can be limited on both sides, so that when the shaft drives the second belt to rotate, the other end is less likely to shake on the first stirring rod, and the transmission is more stable.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] By setting up a fixed-point irrigation device, a hose can be delivered to the root area of ​​the fruit tree that needs watering, and then water can be injected into the root area of ​​the fruit tree, making it easier for the fruit tree to absorb water, improving the full utilization of irrigation water resources, and achieving the effect of saving water resources.

[0027] By setting up a stirring device, solid granular fertilizer placed in irrigation water can be stirred, allowing it to be fully mixed and dissolved with the irrigation water. At the same time, it can also crush solid particles that sink to the bottom of the water bucket to improve dissolution efficiency, and can be used in conjunction with fixed-point irrigation devices for fertilization.

A stirring device 3 is provided inside the water bucket 21. The fixed-point irrigation device 2 can transport the hose 23 to the root position of the fruit tree that needs to be irrigated, and then inject water into the root position of the fruit tree, so that the fruit tree can absorb water and improve the full utilization of irrigation water resources, thereby achieving the effect of saving water resources. The stirring device 3 can stir the solid granular fertilizer put into the irrigation water, so that it can be fully mixed with the irrigation water and dissolved. At the same time, it can also crush the solid particles that sink to the bottom of the water bucket 21 to improve the dissolution efficiency, and cooperate with the fixed-point irrigation device 2 to carry out fertilization treatment. When using the irrigation cart 1 to irrigate the fruit trees in the orchard, the irrigation cart 1 can be pushed to the side of the fruit tree that needs to be irrigated. Then, the fixed-point irrigation device 2 is activated to transport the hose 23 to the root position of the fruit tree that needs to be irrigated. Water is then injected into the root position of the fruit tree to facilitate the absorption of water by the fruit tree and improve the full utilization of irrigation water resources, thereby achieving the effect of saving water resources. If fertilization is required, after putting the solid granular fertilizer into the water bucket 21, the stirring device 3 can be activated to stir the solid granular fertilizer in the irrigation water so that it can be fully mixed and dissolved with the irrigation water. At the same time, the solid granules that sink to the bottom of the water bucket 21 can be crushed to improve the dissolution efficiency. This is done in conjunction with the fixed-point irrigation device 2 for fertilization.

[0042] Reference Figure 1-11As shown, this embodiment discloses that the bottom of the water bucket 21 is fixedly connected to one side of the irrigation cart 1. A water pump 22 is connected through the outer surface of the bottom of the water bucket 21. The outlet of the water pump 22 is fixedly connected to one end of the hose 23.

A drill bit 212 is fixedly connected to one end of the drill rod 211. A threaded sleeve 213 is rotatably connected to one side of the slide 27, and the threaded sleeve 213 is fitted onto the outer surface of the drill rod 211. A groove 230 is formed on the inner wall of the threaded sleeve 213. A rotating plate 227 is rotatably connected to the inner wall of the groove 230. Torsion springs 228 are fitted and connected to the outer surfaces of both ends of the rotating plate 227. The two ends of the torsion springs 228 are fixedly connected to one side of the inner wall of the groove 230 and one side of the rotating plate 227, respectively. A baffle 229 is fixedly connected to the inner wall of the groove 230. A protruding plate 2 is fixedly connected to the outer surface of one end of the drill rod 211. 26. One end of the convex plate 226 is inserted into the inner wall of the slide groove 230. A one-way bearing 225 is fixedly connected to the outer surface of one end of the drill rod 211. The inner walls of the two ends of the first belts 210 are respectively sleeved on the outer surfaces of the two screw hole blocks 28 and the two ends of the one-way bearing 225. A first telescopic rod 214 is symmetrically fixedly connected to one side of the slide 27. A screw hole abutment cylinder 215 is fixedly connected to one end of the first telescopic rod 214. A first spring 216 is sleeved and connected to the outer surface of the first threaded rod 26. The two ends of the first spring 216 are fixedly connected to one side of the screw hole abutment cylinder 215 and one side of the slide 27, respectively. The inner wall of one end of the screw hole abutment cylinder 215 is threadedly connected to the outer surface of the threaded sleeve 213. The other end of the screw hole abutment cylinder 215... One end of the inner wall is slidably connected to the outer surface of one end of the drill rod 211. The inner wall of one end of the screw hole abutment cylinder 215 is provided with several round holes 217. The flow guide 24 is set between the outer surface of the drill rod 211 and the inner wall of the screw hole abutment cylinder 215. Several outlet pipes of the flow guide 24 are fixedly connected to the inner wall of the round holes 217. Several sliding hole frames 218 are fixedly connected to one side of the drill bit 212. The inner wall of the sliding hole frame 218 is slidably connected to the push rod 219. One end of the push rod 219 abuts against the outer surface of one end of the screw hole abutment cylinder 215. One end of the push rod 219 is fixedly connected to the support plate 220. One side of one end of the push rod 219 is fixedly connected to the second spring 221. One end of the second spring 221 is fixedly connected to one side of the sliding hole frame 218.When using the irrigation cart 1 to irrigate the fruit trees in the orchard, the irrigation cart 1 can be pushed to the side of the fruit tree that needs to be irrigated. Then, the dual-axis servo motor 29 on the slide 27 is started to drive the drill rod 211 and drill bit 212 to rotate counterclockwise on the slide 27. At this time, the convex plate 226 can be driven to slide circumferentially around the drill rod 211 in the inner wall of the groove 230. When one end rotates to one side of the rotating plate 227, it will push the rotating plate 227 to rotate away from the baffle 229, causing the torsion spring 228 to deform. At this time, the rotating plate 227 can no longer limit and fix the convex plate 226, so the rotation of the drill rod 211 will not drive the threaded sleeve 213 to rotate. At this time, the inner ring of the one-way bearing 225 on one end of the drill rod 211 will be in contact with the threaded sleeve 213. The outer ring engages and limits the rotation, causing the one-way bearing 225 to rotate when the drill rod 211 rotates counterclockwise. Driven by the two first belts 210, this causes the two screw hole blocks 28 to rotate helically on the outer surfaces of the two threaded rods 26, causing the slide 27 to slide downwards within the inner wall of the groove frame 25. This allows the rotating drill rod 211 and drill bit 212 to move downwards while rotating, drilling holes at the locations where the fruit trees require irrigation. The hose 23, several push plates, and screw hole abutment cylinder 215 are then transported to a position near the roots of the fruit tree. Once transported to a certain position, the dual-axis servo motor 29 is activated, causing the drill rod 211 to rotate clockwise. At this point, the inner and outer rings of the one-way bearing 225 disengage, thus preventing... The first belt 210 rotates, preventing the slide 27 from continuing its downward movement. The drill rod 211 rotates clockwise, causing the protruding plate 226 to rotate clockwise within the inner wall of the groove 230, so that one end of it abuts against the side of the rotating plate 227 away from the baffle 229. The other side of the rotating plate 227 is limited and fixed by the baffle 229, thus limiting the protruding plate 226. At this point, the threaded sleeve 213 can rotate on the slide 27. Then, under the limiting action of the first telescopic rod 214 and the first spring 216, one end of the threaded hole abutment cylinder 215 can move downwards along the threaded surface of the threaded sleeve 213, while the other end slides downwards along the outer surface of the drill rod 211, pulling the guide frame 24 downwards via the hose 23. Meanwhile, the outer surface of one end of the screw hole abutting cylinder 215 will abut against one end of several push rods 219, causing it to slide to one end in the inner wall of the sliding hole frame 218, which will cause the second spring 221 to be stretched open, thereby causing the support plate 220 to be pushed outward in the drill hole, pushing the soil in the drill hole to both ends, increasing the area of ​​the water injection hole, so that a corresponding amount of irrigation water can be injected on one side during later irrigation, improving irrigation efficiency. During irrigation, the water pump 22 can be started to draw water from the water tank into the hose 23 and then into the round hole 217 through the guide frame 24, and finally injected into the drill hole for fixed-point irrigation of fruit trees. This can reduce the probability of water resources being absorbed by other weeds, improve irrigation effect and water resource utilization, and achieve the effect of saving water resources.

By setting the rollers 223, the contact wear between the screw hole abutment cylinder 215 and the push rod 219 can be reduced, making it easier for the screw hole abutment cylinder 215 to push the push rod 219, resulting in smoother operation.

Then, one output of the dual-axis servo motor 29 is activated, driving the limit telescopic rod 312 and the round shaft 33 to rotate on the bracket 313. Driven by the second belt 32, the first stirring rod 31, several stirring blades 34, and the second stirring rod 35 rotate within the inner wall of water bucket 21, mixing the added fertilizer granules and water to ensure thorough contact and dissolution. When some fertilizer granules sink to the bottom of water bucket 21, the second stirring rod 35 and several crushing blocks 36, while rotating on the round shaft 33, stir the slumped fertilizer granules and crush them with their outer surfaces against the bottom of water bucket 21, accelerating the dissolution process. This, combined with subsequent irrigation by the fixed-point irrigation device 2, improves irrigation efficiency.

[0046] Reference Figure 1-11 As shown in this embodiment, a plurality of toothed scrapers 37 are fixedly connected to the outer surface of the second stirring rod 35, and the toothed scrapers 37 and the plurality of crushing blocks 36 are distributed in an alternating manner. By setting the toothed scrapers 37, after the crushing blocks 36 crush the fertilizer particles that have sunk to the bottom of the water bucket 21, some fertilizer powder may adhere to the bottom of the water bucket 21. At this time, the scrapers can scrape off the fragments adhering to the bottom of the water bucket 21, so that the crushed fertilizer powder can be quickly dissolved. A bevel gear 39 is fixedly connected to one side of the second stirring rod 35, and a bevel gear ring block 38 is fixedly connected to the inner wall of the water bucket 21. One side of the bevel gear ring block 38 meshes with the outer surface of the bevel gear 39. By setting up bevel gear 39 and bevel gear ring block 38, while the first stirring rod 31 rotates and drives the second stirring rod 35 to rotate circumferentially, the bevel gear 39 will mesh and rotate on the bevel gear ring block 38, thereby driving the second stirring rod 35 to rotate on its own axis. This drives several crushing blocks 36 and several scraper plates 37 to crush and scrape the fertilizer particles that have sunk to the bottom of the water bucket 21, making it easier for the fertilizer to fully contact the water and dissolve, thus accelerating the dissolution speed of the fertilizer particles.

[0047] Reference Figure 1-11 As shown, this embodiment discloses a connecting bearing 310 fixedly connected to the outer surface of one end of the second stirring rod 35, and the outer ring of the connecting bearing 310 is fixedly connected to the outer surface of one end of the first stirring rod 31. By setting the connecting bearing 310, the rotational wear at the connection between the second stirring rod 35 and the first stirring rod 31 can be reduced, facilitating the rotation of the second stirring rod 35 and improving the service life of both. A limiting ring block 311 is symmetrically fixedly connected to the outer surface of one end of the first stirring rod 31, and one end of the second belt 32 is positioned between the two limiting ring blocks 311. By setting the limiting ring blocks 311, the two sides of one end of the second belt 32 on the first stirring rod 31 can be limited, so that when the shaft 33 drives the second belt 32 to rotate, the other end is less likely to wobble on the first stirring rod 31, making the transmission more stable.

[0048] The working principle is as follows: When using the irrigation cart 1 to irrigate the fruit trees in the orchard, the irrigation cart 1 can be pushed to the side of the fruit tree that needs to be irrigated. Then, the dual-axis servo motor 29 on the slide 27 is started to drive the drill rod 211 and drill bit 212 to rotate counterclockwise on the slide 27. At this time, the convex plate 226 can slide circumferentially around the drill rod 211 in the inner wall of the groove 230. When one end rotates to one side of the rotating plate 227, it will push the rotating plate 227 to rotate away from the baffle 229, causing the torsion spring 228 to deform. At this time, the rotating plate 227 can no longer limit and fix the convex plate 226, so the rotation of the drill rod 211 will not drive the threaded sleeve 213 to rotate. At this time, the one-way bearing 225 on one end of the drill rod 211... The inner ring engages with the outer ring to limit the rotation, causing the one-way bearing 225 to rotate when the drill rod 211 rotates counterclockwise. Driven by the two first belts 210, the two screw hole blocks 28 rotate helically on the outer surfaces of the two threaded rods 26, causing the slide 27 to slide downwards within the inner wall of the groove frame 25. The dual-axis servo motor 29 moves downwards accordingly, while the connecting telescopic rod 312 is stretched, allowing the rotating drill rod 211 and drill bit 212 to move downwards while rotating. Drilling is performed at the location where the fruit tree needs irrigation. The hose 23, several push plates, and screw hole abutment cylinder 215 are transported to a position near the root of the fruit tree. Once transported to a certain position, the dual-axis servo motor 29 is activated to drive the drill rod 211... When the drill rod 211 rotates clockwise, the inner and outer rings of the one-way bearing 225 disengage, preventing the first belt 210 from rotating and thus stopping the slide 27 from descending. The clockwise rotation of the drill rod 211 causes the protruding plate 226 to rotate clockwise within the inner wall of the groove 230, so that one end of it abuts against the side of the rotating plate 227 away from the baffle 229. The other side of the rotating plate 227 is limited and fixed by the baffle 229, thus limiting the protruding plate 226. This allows the threaded sleeve 213 to rotate on the slide 27. Then, under the limiting action of the first telescopic rod 214 and the first spring 216, one end of the threaded hole abutment cylinder 215 moves downwards along the threaded outer surface of the threaded sleeve 213, while the other end moves downwards along the drill rod 211. The outer surface of the tube 11 slides downwards, pulling the guide frame 24 downwards via the hose 23. Simultaneously, one end of the outer surface of the screw hole abutting cylinder 215 abuts against one end of several push rods 219, causing it to slide towards one end within the inner wall of the sliding hole frame 218. This stretches the second spring 221, causing the support plate 220 to expand outwards within the borehole, pushing the soil in the borehole towards both ends and increasing the area of ​​the water injection hole. This facilitates the injection of a corresponding amount of irrigation water from one side during later irrigation, improving irrigation efficiency. During irrigation, the water pump 22 can be activated to draw water from the tank into the hose 23, then through the guide frame 24 into the round hole 217, and finally into the borehole, providing targeted irrigation for the fruit trees. This reduces the probability of water resources being absorbed by other weeds.To improve irrigation efficiency and water resource utilization, thereby achieving water conservation.

[0049] When fertilizing fruit trees, fertilizer granules can be added into the water tank 21 through the inlet, followed by the appropriate amount of water. Then, one of the output ends of the dual-axis servo motor 29 is started, driving the limit telescopic rod 312 and the round shaft 33 to rotate on the bracket 313. Under the transmission of the second belt 32, the first stirring rod 31, several stirring blades 34, and the second stirring rod 35 can rotate inside the water tank 21, stirring and mixing the added fertilizer granules and water so that they can fully contact and dissolve. When some fertilizer granules sink to the bottom of the water tank 21, the first stirring rod 31 rotates, driving the second stirring rod 35 to rotate in a circular motion. At the same time, the bevel gear 39 will mesh and rotate on the bevel gear ring block 38, thereby driving the second stirring rod 35 to rotate on its own axis. This drives several crushing blocks 36 and several scraper blades 37 to crush and scrape the fertilizer granules that have sunk to the bottom of the water tank 21, making it easier for the fertilizer to fully contact the water and dissolve, thus accelerating the dissolution speed of the fertilizer granules.
