Description

Technical Field

[0001] The invention relates to the technical field of automatic irrigation equipment, in particular to an irrigation system for strawberry planting. Background Art

[0002] The current automatic irrigation system for strawberry greenhouses can be divided into preset pipeline type and mobile irrigation type. The preset pipeline type requires the pre-laying or installation of irrigation pipelines according to the planting plan. Once the pipeline is set up, the subsequent strawberry seedling planting location can only be selected at the various nozzles of the irrigation pipeline, making it difficult to flexibly adjust the planting scale and density.

[0003] The mobile irrigation type performs mobile irrigation by hanging the irrigation nozzle on a bracket that can move along the planting direction of the strawberry seedlings. The planting scale of strawberries can be flexibly adjusted according to demand. However, in order to supply water to the pipes on the mobile bracket, it is necessary to connect the external water source to the pipes on the mobile bracket through a hose. In order to ensure that the mobile bracket has sufficient travel, a long distance needs to be reserved for the hose, and multiple sections need to be suspended on the accompanying pipe rack, so that the pipe diameter is long and has multiple corners. The total pipe resistance of the pipeline system is large, and a large-lift water pump needs to be selected, which requires a large power consumption when the device is in operation. At the same time, the number of irrigation nozzles installed on the mobile bracket is fixed and cannot be adjusted according to the planting scale, and the flexibility is relatively limited. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing automatic strawberry irrigation system cannot be flexibly adjusted according to the planting scale, and the pipeline resistance of the mobile irrigation is relatively large. An irrigation system for strawberry planting is provided.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a strawberry planting irrigation system, which includes a bracket, a greenhouse and a track, wherein the brackets are arranged on both sides inside the greenhouse, a fixed water trough is provided on the top of one side of the bracket, a track is fixedly arranged in the middle of the bracket, a mobile water trough traveling along the track is provided on the track, a first siphon is provided on the side of the mobile water trough to connect the fixed water trough and the mobile water trough, a plurality of second siphons are provided on the edge of the mobile water trough, and an irrigation pipe is arranged at the end of the second siphon.

Chutes for cooperating with the limiting rods are arranged on both sides of the water inlet pipe. A first compression spring for driving the sliding tube is arranged inside the water inlet pipe, and a second compression spring for driving the valve core is arranged inside the valve seat. The first compression spring drives the sliding tube to push and extend the valve core downward through the spherical head push rod and compress the second compression spring.

[0009] Furthermore, a limiting ring for cooperating with the limiting rods is fixedly arranged at the connection part of the first elbow pipe and the central pipe. The limiting rod is in fit with the outer ring of the limiting ring, and a concave groove is arranged at the top of the limiting ring.

[0010] Furthermore, a water supply pipe is arranged inside the greenhouse. The water supply pipe extends upward and is communicated with a three-way switching valve. The three-way switching valve is respectively communicated with a first water injection pipe and a second water injection pipe. The top of the water inlet pipe is funnel-shaped, the top opening is aligned with the end of the first water injection pipe, and the bottom is communicated with the sliding tube. The second water injection pipe extends above the fixed water tank.

[0011] Furthermore, a first electric cylinder is arranged at the end of the fixed water tank. The power end of the first electric cylinder drives a horizontally sliding slider. A counterweight roller is arranged on the side surface of the T-shaped pipe sleeve. The slider pushes the counterweight roller to rotate the T-shaped pipe sleeve.

[0012] Furthermore, the second siphon pipe includes a second elbow pipe, a first three-way pipe, a second three-way pipe and a suction piston cylinder.

[0016] The advantages of the present invention compared with the prior art are as follows:

[0017] While ensuring that the irrigation pipe can move along the planting direction of strawberries, the use of hose connection is avoided, and the overall pipe length is reduced.

[0018] Since the overall header is relatively low and there are bends only in some of the pipelines, the overall pipeline resistance is reduced. Therefore, a water pump with a lower head can be selected, reducing the power consumption of the water pump during the use of the device.

[0019] The number of irrigation pipes can be increased or decreased according to the actual planting situation, and the installation is relatively simple, making the irrigation system have a certain degree of flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Combined with the attached Figure 1 、attached Figure 2 、attached Figure 3 and attached Figure 4, An irrigation system for strawberry cultivation, which includes a bracket 1, a greenhouse 4, and a track 5. The bracket 1 is arranged on both sides inside the greenhouse 4. On top of one side of the bracket 1, there is a fixed water tank 2. In the middle of the bracket 1, the track 5 is fixedly arranged. On the track 5, there is a movable water tank 3 that travels along the track 5. On the side of the movable water tank 3, there is a first siphon tube 7 that connects the fixed water tank 2 and the movable water tank 3. At the edge of the movable water tank 3, there are multiple second siphon tubes 8. The ends of the second siphon tubes 8 are connected to an irrigation pipe 10. At the bottom end of the irrigation pipe 10, an irrigation nozzle 11 is arranged for irrigation. The first siphon tube 7 moves with the movable water tank 3, with one end inside the movable water tank 3 and the other end moving inside the fixed water tank 2.

[0041] Combined with the attached Figure 5 and the attached Figure 6 , At the bottom of the movable water tank 3, a load-bearing beam 16 is arranged. At both ends of the sides of the load-bearing beam 16, walking motors 6 are arranged. The walking motors 6 are drivingly connected to a transfer gearbox 17. The front and back of the transfer gearbox 17 are drivingly connected to walking wheels 18 that cooperate with the track 5.

[0042] The traveling direction of this device is the same as the strawberry cultivation direction. The irrigation nozzle 11 extends to the soil at the root of the strawberry. The movable water tank 3 moves along the strawberry cultivation direction. While the irrigation nozzle 11 moves along the strawberry root, it sprays irrigation. During this process, the first siphon tube 7 keeps the liquid levels in the fixed water tank 2 and the movable water tank 3 equal. The second siphon tube 8 guides the water in the movable water tank 3 to the irrigation pipe 10 through a regulating valve 9. By injecting water into the fixed water tank 2 from an external water source, irrigation can be sprayed while keeping the irrigation nozzle 11 moving along the strawberry root through the above water path.

[0043] Since this device uses the siphon principle to achieve the flow of liquid in the fixed water tank 2 to the movable water tank 3, and the flow of liquid in the movable water tank 3 to the irrigation pipe 10, the siphon principle requires keeping the two ends of the liquid connected, and the siphon tube needs to be pre-filled with water.

[0044] To achieve water injection into the siphon tube, this device provides the following structure:

[0045] Combined with the attached Figure 9 and the attached Figure 10 , The first siphon tube 7 includes a first elbow 22, a central tube 24, and a T-shaped tube sleeve 25. Both ends of the central tube 24 are connected to the first elbow 22. The ends of the first elbows 22 on both sides extend into the fixed water tank 2 and the movable water tank 3 respectively. A first siphon tube bracket 23 is commonly arranged outside the first elbow 22 and the central tube 24. The first siphon tube bracket 23 is erected on the edge of the movable water tank 3. The T-shaped tube sleeve 25 is rotatably sleeved outside the central tube 24. There is a water injection hole 26 at the top of the central tube 24. There is a water inlet pipe 29 and a counterweight roller 34 on the side of the T-shaped tube sleeve 25.

[0046] In the above structure, there is an included angle between the direction of the water inlet pipe 29 and the installation direction of the counterweight roller 34. When no external force is applied to the T-shaped pipe sleeve 25, the gravity of the counterweight roller 34 pulls the T-shaped pipe sleeve 25, making it impossible for the water inlet pipe 29 to align with the water injection hole 26.

[0047] Combined with the attached Figure 11 and the attached Figure 12 , a valve seat 27 is fixedly arranged at the inner bottom of the central pipe 24. A valve core 28 that slides vertically is arranged at the center of the valve seat 27. When the valve core 28 moves upward, it closes the water injection hole 26. The valve seat 27 and the valve core 28 can only open and close the water injection hole 26 and cannot affect the liquid flow at both ends of the central pipe 24. Moreover, both the valve seat 27 and the valve core 28 are set in a spindle shape to reduce the liquid flow resistance.

[0048] Combined with the attached Figure 11 and the attached Figure 12 , a sliding pipe 30 is slidably sleeved inside the water inlet pipe 29. A spherical head push rod 31 is fixedly arranged at the bottom of the sliding pipe 30, and limiting rods 32 are fixedly arranged on both sides. Chutes 33 that cooperate with the limiting rods 32 are arranged on both sides of the water inlet pipe 29. A first compression spring 37 for driving the sliding pipe 30 is arranged inside the water inlet pipe 29, and a second compression spring 38 for driving the valve core 28 is arranged inside the valve seat 27.

[0049] In the above structure, the elastic force of the first compression spring 37 is greater than that of the second compression spring 38. When the water inlet pipe 29 aligns with the water injection hole 26, the first compression spring 37 drives the sliding pipe 30 to push down the valve core 28 through the spherical head push rod 31 and compress the second compression spring 38.

[0050] Combined with the attached Figure 11 and the attached Figure 12 , a limiting ring 35 that cooperates with the limiting rods 32 is fixedly arranged at the connection between the first elbow pipe 22 and the central pipe 24. The limiting rods 32 are in contact with the outer ring of the limiting ring 35, and a concave groove 36 is arranged at the top of the limiting ring 35.

[0051] The contour of the limiting ring 35 ensures that during the rotation of the T-shaped pipe sleeve 25, when the spherical head push rod 31 contacts the top edge of the valve core 28 until the water inlet pipe 29 is completely aligned with the water injection hole 26, the first compression spring 37 gradually presses down the sliding pipe 30 at a lower speed. When the water inlet pipe 29 is completely aligned with the water injection hole 26, the limiting rods 32 are at the lowest point of the concave groove 36. Conversely, the concave groove 36 gradually lifts the sliding pipe 30 through the limiting rods 32 to prevent the spherical head push rod 31 from colliding with the water injection hole 26.

[0052] Combined with the attached Figure 7 , the attached Figure 8 , the attached Figure 13 , the attached Figure 14 , the attached Figure 15 and the attached Figure 16, a water supply pipe 12 is provided in the greenhouse 4. The water supply pipe 12 extends upward and is connected to a three-way switching valve 13. The three-way switching valve 13 is respectively connected to a first water injection pipe 14 and a second water injection pipe 15. The top of the water inlet pipe 29 is funnel-shaped. When the top opening of the water inlet pipe 29 is completely aligned with the water injection hole 26, the top funnel of it is aligned with the end of the first water injection pipe 14, and the bottom is connected to the sliding pipe 30. The second water injection pipe 15 extends above the fixed water tank 2.

[0053] Combined with the attached Figure 14 , a first electric cylinder 19 is provided at the end of the fixed water tank 2. The power end of the first electric cylinder 19 drives a horizontally sliding slider 21. The slider 21 is slidably connected to the fixed water tank 2 through a guide rod 20. A counterweight roller 34 is arranged on the side of the T-shaped pipe sleeve 25. The slider 21 pushes the counterweight roller 34 to rotate the T-shaped pipe sleeve 25.

[0054] When the device needs to start working, first control the moving water tank 3 to move to the end of the fixed water tank 2, and control the first electric cylinder 19 to push the counterweight roller 34 through the slider 21 to rotate the T-shaped pipe sleeve 25 until the upper funnel of the water inlet pipe 29 is aligned with the first water injection pipe 14 and the lower part is completely aligned with the water injection hole 26. In this state, the water inlet pipe 29 is connected to the central pipe 24, and water is injected through the water supply pipe 12. Adjust the three-way switching valve 13 to connect the first water injection pipe 14 with the water supply pipe 12. After the injected water flow leaves the first water injection pipe 14, it enters the top funnel of the water inlet pipe 29, and then enters the central pipe 24 through the sliding pipe 30 and respectively enters the fixed water tank 2 and the moving water tank 3 from the first elbow pipes 22 on both sides.

[0055] After the liquid levels in the fixed water tank 2 and the moving water tank 3 reach an appropriate height, stop adding water and at the same time control the first electric cylinder 19 to retract the slider 21. In this state, the gravity of the counterweight roller 34 drives the T-shaped pipe sleeve 25 to rotate, and the groove 36 gradually lifts the sliding pipe 30 through the limiting rod 32, and the valve core 28 closes the water injection hole 26. After this process ends, there is still liquid remaining in the first elbow pipe 22 and the central pipe 24 to maintain the siphon effect.

[0056] When the device is working, the siphon effect between the first elbow pipe 22 and the central pipe 24 always keeps the liquid levels in the fixed water tank 2 and the moving water tank 3 connected. By controlling the three-way switching valve 13 to connect the second water injection pipe 15 with the water supply pipe 12, injecting water into the fixed water tank 2 can realize the water replenishment of the moving water tank 3.

[0057] Combined with the attached Figure 17The second siphon 8 includes a second elbow 39, a first three-way joint 40, a second three-way joint 43, and a suction piston cylinder 45. A second siphon bracket 41 is commonly provided outside the second elbow 39 and the first three-way joint 40. The second siphon bracket 41 is erected on the edge of the movable water tank 3. The bottom end of the second elbow 39 extends into the movable water tank 3. The top of the first three-way joint 40 communicates with the second elbow 39, and a regulating valve 9 is communicatively provided at the bottom. The outlet of the regulating valve 9 communicates with the irrigation pipe 10. A first one-way valve 42 is communicatively provided on the side of the first three-way joint 40. The outlet of the first one-way valve 42 communicates with the second three-way joint 43. The top of the second three-way joint 43 communicates with the suction piston cylinder 45, and a second one-way valve 44 is communicatively provided on the side.

[0058] The directions of the first one-way valve 42 and the second one-way valve 44 refer to the Figure 17 arrow directions in the appendix.

[0059] Combined with the appendix Figure 17 A vertically moving piston 46 and a third compression spring 48 for driving the piston 46 are provided in the suction piston cylinder 45. A connecting block 47 is provided at the top end of the piston 46, and a driving rod 49 is commonly provided by a plurality of connecting blocks 47.

[0060] By lifting the piston 46 with the regulating valve 9 closed, the second siphon 8 can be suctioned, and the liquid in the movable water tank 3 is suctioned into the second elbow 39 and the first three-way joint 40 to achieve the siphon effect. When suctioning, the regulating valve 9 is closed, and the air in the second elbow 39 and the first three-way joint 40 can only enter the suction piston cylinder 45 through the first one-way valve 42. After releasing the piston 46, the air in the suction piston cylinder 45 is discharged through the second one-way valve 44 by the third compression spring 48.

[0061] Combined with the appendix Figure 18 A guide post 51 is provided at the top of the bracket 1. The guide post 51 is connected to a driving bracket 50 that slides vertically. The two ends of the driving rod 49 are attached to the top of the driving bracket 50. A second electric cylinder 52 is provided on the side of the bottom of the bracket 1, and the power end of the second electric cylinder 52 is connected to the driving bracket 50.

[0062] Since a plurality of second siphons 8 need to be installed on the movable water tank 3, in order to simultaneously control a plurality of pistons 46, the pistons 46 are connected in series by the driving rod 49 and are lifted by the driving bracket 50. This structure can simultaneously suction a plurality of second siphons 8.

[0063] The above describes the present invention and its implementation manners. This description is not restrictive, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
