Description

Technical Field

[0001] The present invention belongs to the technical field of irrigation equipment, and particularly relates to an irrigation device for gardens. Background Art

[0002] Fruit orchards or park forests need to irrigate plants regularly. Traditionally, it is usually necessary to manually fertilize the plants before irrigation, which not only has a large manual labor intensity but also is time-consuming and laborious. To solve this problem, the prior art usually adopts an irrigation pipe network system to irrigate the garden. However, the existing irrigation system is usually fixed on the ground, and then water is sprayed from the center to the outside through a nozzle. Although this method solves the problem of automatic irrigation, due to the large irrigation amount near the nozzle center and the small irrigation amount far from the nozzle center, it is easy to cause uneven irrigation, resulting in waste of water resources. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an irrigation device for gardens, which can improve the uniformity of garden irrigation and is more conducive to the pruning and maintenance of gardens.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An irrigation device for gardens of the present invention includes a mobile trolley, a water pump fixed on the mobile trolley, and a water outlet straight pipe connected to the water outlet end of the water pump. The water inlet end of the water pump is connected to a water source. A central shaft is rotatably arranged outside the water outlet straight pipe. The central shaft is integrally connected with a rotating cylinder. The central shaft is rotatably installed on the mobile trolley through a bearing seat, and the central shaft is simultaneously connected with a rotation driving device; a plurality of sprinkler plates are evenly distributed on the outer circumference of the rotating cylinder. One end of the sprinkler plate is connected to the rotating cylinder. Sprinkler holes are formed on both side surfaces of the sprinkler plate. The sprinkler holes are connected to a water pipe through a sprinkler channel formed inside the sprinkler plate. One end of the water pipe is fixed in an installation hole formed on the rotating cylinder, and the other end of the water pipe penetrates through a sealing hole on the water outlet straight pipe and extends into the water outlet straight pipe. The end of the water pipe extending into the water outlet straight pipe extends along the axial direction of the water outlet straight pipe. The water pipe is fixed in the water outlet straight pipe through a sealing limiting plate. The water inlet ends of the water pipes corresponding to each sprinkler plate are located in the same cross-section of the water outlet straight pipe; an opening corresponding to the rotating cylinder is formed on the mobile trolley.

[0006] Further, the sprinkler channel includes a main channel and a plurality of branch channels. The main channel extends along the length direction of the sprinkler plate. One end of the main channel is communicated with the water pipe through an installation hole, and the other end of the main channel extends towards the outer end of the sprinkler plate. The branch channels are vertically arranged on both sides of the main channel, and the outer ends of the branch channels are communicated with the sprinkler holes.

[0007] Further, a limiting plate is fixed at one end of the water pipe located inside the installation hole. A through hole communicating with the water pipe is provided on the limiting plate. The limiting plate is connected to a ball through a first tension spring, and the outer diameter of the ball is adapted to the inner diameter of the main channel.

[0008] Further, a second tension spring is installed in the water spraying hole, and the outer end of the tension spring is connected to a cover.

[0009] Further, the rotation driving device includes a toothed ring, a gear and a motor. The toothed ring is coaxially arranged outside the central shaft. The toothed ring meshes with the gear. The gear is connected to the output end of the motor, and the motor is installed on the moving trolley.

[0010] Further, a shaft shoulder is provided on the outside of the central shaft. The end face of the shaft shoulder cooperates with the bearing seat, and the bearing seat is used for axially limiting the central shaft.

[0011] Further, a guide hole is provided on the outer wall of the rotating cylinder. A shifting rod is slidably inserted into the guide hole. The length of the shifting rod extending out of the rotating cylinder is greater than the length of the water spraying plate. The inner end of the shifting rod extends radially into the rotating cylinder. The inner end of the shifting rod is slidably arranged inside an outer rod. The outer rod is fixed outside the rotating bearing, and the rotating bearing is installed outside the straight water outlet pipe; a baffle is fixed on the shifting rod, and a supporting spring is arranged between the baffle and the outer rod. The supporting spring is sleeved outside the shifting rod.

[0012] Further, ventilation holes are provided on the outer wall of the rotating cylinder. The ventilation holes communicate the inside and outside of the rotating cylinder. A cooling water inlet is provided on the end face of the rotating cylinder.

[0013] Further, a fan blade is fixed outside the outer rod, and the fan blade corresponds to the ventilation hole.

[0014] The beneficial effects of the present invention are as follows:

[0015] A watering device for gardens disclosed by the present invention waters the garden area through the water spraying plates on the rotating cylinder. By rotating the rotating cylinder, the water can be evenly sprayed out. Then, the rotating cylinder is moved to different positions by the moving trolley to solve the problem of uneven watering caused by the traditional fixed watering method.

[0016] In the watering device disclosed by the present invention, the water inlet ends of the water pipes corresponding to the respective water spraying plates are located in the same cross section of the straight water outlet pipe. Therefore, it can be ensured that the water flow rates entering the respective water pipes in the straight water outlet pipe are basically the same, and thus the water output from the water spraying plates is also basically the same, solving the technical problems in the background art.

[0017] In the watering device disclosed by the present invention, since water is thrown out from the side of the sprinkler plate, the influence of the centrifugal force of the rotating cylinder on water discharge is reduced, and the uniformity of water discharge is better guaranteed. The outer wall of the rotating cylinder provides a protective space for the water pipe to prevent the water pipe from being damaged. The rotating cylinder also limits the watering radius of the sprinkler plate, so that water can be scattered more dispersedly.

Detailed Embodiments

[0027] As Figures 1 to 6As shown in the figure, a watering device for gardens according to the present invention includes a mobile trolley 1, a water pump 2 fixed on the mobile trolley 1, and a straight water outlet pipe 3 connected to the water outlet end of the water pump 2. The water inlet end of the water pump 2 is connected to a water source. The water source provides watering water for the straight water outlet pipe 3, and it can be connected to a water tank or a faucet through a pipeline. The water pump 2 provides power to pump the water from the water source to the straight water outlet pipe 3 and then discharge it. The mobile trolley 1 of the present invention adopts the existing technology and can be controlled manually by remote control or automatically.

[0028] Among them, a central shaft 4 is rotatably arranged on the outer side of the straight water outlet pipe 3. The central shaft 4 is a hollow shaft. The central shaft 4 is rotatably installed on the mobile trolley 1 through a bearing seat 6. The central shaft 4 is coaxially and rotatably installed on the outer side of the straight water outlet pipe 3. The straight water outlet pipe 3 does not rotate, and the central shaft 4 can rotate around the axis of the straight water outlet pipe 3. The central shaft 4 is integrally connected with a rotating cylinder 5. The diameter of the rotating cylinder 5 is larger than the outer diameter of the central shaft 4, and a cavity is formed inside the rotating cylinder 5 for installing various water pipes 10.

[0029] Specifically, the central shaft 4 is also connected to a rotation driving device 7. The rotation driving device 7 is used to drive the central shaft 4 to rotate. When the central shaft 4 rotates, it can drive the rotating cylinder 5 to rotate together, so that the sprinkler plate 8 on the outer side of the rotating cylinder 5 sprinkles water, so as to play a role in watering the garden.

[0030] A number of sprinkler plates 8 are evenly distributed on the outer circumference of the rotating cylinder 5. Four groups of sprinkler plates 8 are arranged along the axial direction. Six sprinkler plates 8 in each group are evenly spaced along the circumferential direction of the rotating cylinder 5. One end of the sprinkler plate 8 is connected to the rotating cylinder 5 for receiving the water flowing out of the straight water outlet pipe 3. Sprinkler holes 9 are opened on both sides of the sprinkler plate 8. The sprinkler holes 9 are connected to the water pipe 10 through a sprinkler channel opened inside the sprinkler plate 8. The water in the water pipe 10 enters the sprinkler holes 9 through the sprinkler channel, playing a role in side spraying.

[0031] One end of the water pipe 10 is fixed in the installation hole 11 opened on the rotating cylinder 5. The water pipe 10 is in sealed cooperation with the inner wall of the installation hole 11 to prevent water leakage. The other end of the water pipe 10 passes through the sealing hole on the straight water outlet pipe 3 and extends deep into the straight water outlet pipe 3. The end of the water pipe 10 extending deep into the straight water outlet pipe 3 extends along the axial direction of the straight water outlet pipe 3. The water pipe 10 is fixed in the straight water outlet pipe 3 through a sealing limit plate 12. The water inlet ends of the water pipes 10 corresponding to each sprinkler plate 8 are located in the same cross-section of the straight water outlet pipe 3; an opening 13 corresponding to the rotating cylinder 5 is opened on the mobile trolley 1. By arranging the water inlet ends of the water pipes 10 corresponding to each sprinkler plate 8 in the same cross-section of the straight water outlet pipe 3, the present invention can ensure that the water flow rates entering each water pipe 10 in the straight water outlet pipe 3 are basically the same, so the amount of water flowing out from the sprinkler plate 8 is also basically the same, so as to solve the problem of uneven watering brought by the traditional watering method.

[0032] In this embodiment, the water sprinkling channel includes a main channel 14 and several branch channels 15. The main channel 14 is located at the center of the water sprinkling plate 8 and extends along the length direction of the water sprinkling plate 8. One end of the main channel 14 is communicated with the water pipe 10 through the mounting hole 11, and the other end of the main channel 14 extends towards the outer end of the water sprinkling plate 8. The branch channels 15 are vertically arranged on both sides of the main channel 14, and the outer ends of the branch channels 15 are communicated to the water sprinkling holes 9. The water in the water pipe 10 first enters the main channel 14 through the mounting hole 11, and then diverges through the water sprinkling holes 9 on the branch channels 15, which not only increases the divergence range, but also reduces the influence of the centrifugal force of the rotating cylinder 5 on the water outlet, and better ensures the uniformity of the water outlet. In this embodiment, there are three groups of branch channels 15, and those skilled in the art can understand that different numbers of branch channels 15 can be selected according to actual density requirements.

[0033] In this embodiment, a limiting plate 16 is fixed at one end of the water pipe 10 located inside the mounting hole 11. A through hole communicated with the water pipe 10 is opened on the limiting plate 16 for the water flow to pass through. The limiting plate 16 is connected to the ball 18 through the first tension spring 17, and the outer diameter of the ball 18 is adapted to the inner diameter of the main channel 14.

[0034] In the present invention, by providing the ball 18, the sum of the gravity of the ball 18 and the tension of the first tension spring 17 is at least greater than the centrifugal force. Taking the plane passing through the axis of the central shaft 4 and parallel to the horizontal plane as the central section, after the rotating cylinder 5 rotates uniformly, when the water sprinkling plate 8 is located above the central section, the ball 18 can be blocked under the action of gravity and the tension of the first spring at the lower side of the main channel 14, thereby closing the main channel 14, avoiding water from being sprinkled onto the mobile trolley 1 from above, and avoiding the waste of water resources and the problem of uneven irrigation. When the water sprinkling plate 8 is located below the central section, the ball 18 can cooperate with the centrifugal force to pull the first tension spring 17 under the action of gravity, and the ball 18 moves downward to connect the main channel 14 and the branch channels 15, and the water flow can be sprinkled out normally. By adopting the above method, it can be ensured that the direction of the irrigating water flow is always towards the lower part of the central section, reducing the waste of water resources.

[0035] In this embodiment, a second tension spring 19 is installed in the water sprinkling hole 9, and the outer end of the tension spring is connected to the sealing cover 20. The tension of the second tension spring 19 is small, and during irrigation, the water flow can be ejected under the action of pressure. After irrigation is completed, the sealing cover 20 can close the water sprinkling hole 9 under the action of the pre-tension, thereby reducing the accumulation of dust or impurities in the water sprinkling hole 9 and preventing blockage.

[0036] In this embodiment, the rotation driving device includes a toothed ring 21, a gear 22 and a motor 23. The toothed ring 21 is coaxially arranged outside the central shaft 4. The toothed ring 21 meshes with the gear 22. The gear 22 is connected to the output end of the motor 23, and the motor 23 is installed on the mobile trolley 1. By controlling the motor 23, the rotation speed of the central shaft 4 can be controlled. Further, a shaft shoulder 24 is provided on the outside of the central shaft 4. The end face of the shaft shoulder 24 cooperates with the bearing seat 6. The bearing seat 6 is used to limit the axial direction of the central shaft 4 to prevent the central shaft 4 from axially moving when rotating.

[0037] In this embodiment, a guide hole 25 is provided on the outer wall of the rotating cylinder 5. The guide hole 25 extends along the radial direction of the rotating cylinder 5. A toggle rod 26 is slidably inserted into the guide hole 25. The length of the toggle rod 26 extending out of the rotating cylinder 5 is greater than the length of the sprinkler plate 8. The inner end of the toggle rod 26 extends radially into the rotating cylinder 5. The inner end of the toggle rod 26 is slidably arranged inside the outer rod 27. The outer rod 27 is fixed outside the rotary bearing 28, and the rotary bearing 28 is installed outside the water outlet straight pipe 3; a baffle 29 is fixed on the toggle rod 26. A support spring 30 is arranged between the baffle 29 and the outer rod 27. The support spring 30 is sleeved outside the toggle rod 26. In the present invention, by providing the toggle rod 26, since the outer end of the toggle rod 26 is longer, after the toggle rod 26 rotates, the toggle rod 26 can play a role in removing impurities such as weeds and branches, so the sprinkler plate 8 can be protected to a certain extent. By elastically connecting the toggle rod 26 with the support spring 30, when encountering a hard object, the hard object can be avoided in time. A pressure sensor is arranged inside the outer rod 27. When the pressure sensor senses the pressure of the toggle rod 26, an alarm can be given, and the controller controls the motor 23 to stop rotating, avoiding further damage to the device.

[0038] In this embodiment, ventilation holes 31 are provided on the outer wall of the rotating cylinder 5. The ventilation holes 31 communicate the inside and outside of the rotating cylinder 5. A cooling water inlet 32 is provided on the end face of the rotating cylinder 5. By providing the ventilation holes 31, when the rotating cylinder 5 rotates, air can flow inside and outside the rotating cylinder 5, which can play a role in cooling and avoid damage to the garden due to too high water source temperature.

[0039] In this embodiment, a fan blade 33 is fixed outside the outer rod 27. The fan blade 33 corresponds to the ventilation hole 31, which can increase the air flow inside the rotating cylinder 5, so the heat dissipation effect can be improved.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
