Description

Technical Field

[0001] The present invention relates to the technical field of automatic irrigation equipment, and specifically refers to an irrigation system for strawberry cultivation. Background Art

[0002] The current automatic irrigation systems for strawberry greenhouses can be divided into a preset pipeline type and a mobile irrigation type. Among them, the preset pipeline type requires pre-laying or erecting irrigation pipelines according to the planting plan. Once the pipelines are set up, the subsequent planting positions of strawberry seedlings can only be selected at the spray nozzles of the irrigation pipelines, making it difficult to flexibly adjust the planting scale and density.

[0003] The mobile irrigation type conducts mobile irrigation by suspending the irrigation nozzles on a bracket that can move along the planting direction of strawberry seedlings. The planting scale of strawberries can be flexibly adjusted according to needs. However, in order to supply water to the pipelines on the mobile bracket, it is necessary to connect the external water source to the pipelines on the mobile bracket through a hose. To ensure that the mobile bracket has enough travel, the hose needs to reserve a long distance and needs to be suspended on the accompanying pipe rack in multiple sections, resulting in a long pipe diameter and multiple corners, and a large total pipe resistance of the pipeline system. It is necessary to select a water pump with a large lift, so that the device requires a large amount of electricity consumption during 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 irrigation system for strawberries cannot be flexibly adjusted according to the planting scale, and the pipe resistance of the mobile irrigation pipeline is relatively large. The present invention provides an irrigation system for strawberry cultivation.

[0005] To solve the above technical problem, the technical solution provided by the present invention is: an irrigation system for strawberry cultivation, which includes a bracket, a greenhouse, and a track. The brackets are arranged on both sides inside the greenhouse. A fixed water tank is provided at the top of one of the brackets. A track is fixedly arranged in the middle of the bracket. A mobile water tank that travels along the track is provided on the track. A first siphon tube is provided on the side of the mobile water tank to connect the fixed water tank and the mobile water tank. A plurality of second siphon tubes are provided at the edge of the mobile water tank, and the ends of the second siphon tubes are connected to an irrigation pipe.

[0006] The first siphon tube includes a first elbow tube, a central tube, and a T-shaped tube sleeve. Both ends of the central tube are connected to a first elbow tube. The ends of the first elbow tubes on both sides extend into the fixed water tank and the mobile water tank respectively. The T-shaped tube sleeve is rotatably sleeved outside the central tube. A water injection hole is provided at the top of the central tube, and a water inlet pipe is provided on the side of the T-shaped tube sleeve.

[0007] Further, a valve seat is fixedly arranged at the bottom inside the central tube, and a valve core that slides vertically is arranged at the center of the valve seat. When the valve core moves upward, the water injection hole is closed.

[0008] Further, a sliding tube is sleeved inside the water inlet pipe in a sliding manner. A spherical head push rod is fixedly arranged at the bottom of the sliding tube, and limiting rods are fixedly arranged on both sides. 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 the valve core downward through the spherical head push rod and compress the second compression spring.

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

[0010] Further, 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] Further, 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 of the T-shaped pipe sleeve. The slider pushes the counterweight roller to rotate the T-shaped pipe sleeve.

[0012] Further, the second siphon pipe includes a second elbow pipe, a first three-way pipe, a second three-way pipe and a suction piston cylinder. The top of the first three-way pipe is communicated with the second elbow pipe, a regulating valve is communicated at the bottom, the outlet of the regulating valve is communicated with the irrigation pipe, a first one-way valve is communicated on the side of the first three-way pipe, the outlet of the first one-way valve is communicated with the second three-way pipe, the top of the second three-way pipe is communicated with the suction piston cylinder, and a second one-way valve is communicated on the side.

[0013] Further, a piston moving vertically and a third compression spring for driving the piston are arranged inside the suction piston cylinder. A connecting block is arranged at the end of the top of the piston, and a driving rod is jointly arranged by a plurality of connecting blocks.

[0014] Further, a guide post is arranged at the top of the bracket. The guide post is connected with a driving bracket sliding vertically. The ends of both sides of the driving rod are in contact with the top of the driving bracket. A second electric cylinder is arranged on the side of the bottom of the bracket, and the power end of the second electric cylinder is connected with the driving bracket.

[0015] Further, a load-bearing beam is arranged at the bottom of the movable water tank. Walking motors are arranged at the ends of both sides of the load-bearing beam. The walking motors are drivingly connected with a transfer gearbox, and the front and back of the transfer gearbox are drivingly connected with walking wheels cooperating with the track.

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

[0017] While ensuring that the pipeline of the irrigation pipe can move along the planting direction of strawberries, the use of a 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 the pipelines at some positions, the overall pipeline resistance is reduced. Therefore, a water transfer pump with a lower lift can be selected, reducing the electricity consumption of the 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. A fixed water tank 2 is provided at the top of one side of the bracket 1. The track 5 is fixedly arranged in the middle of the bracket 1. A movable water tank 3 moving along the track 5 is provided on the track 5. A first siphon tube 7 is provided on the side of the movable water tank 3 to connect the fixed water tank 2 and the movable water tank 3. A plurality of second siphon tubes 8 are provided at the edge of the movable water tank 3. The end of the second siphon tube 8 is connected to an irrigation pipe 10. An irrigation nozzle 11 is provided at the bottom end of the irrigation pipe 10 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 , A load-bearing beam 16 is provided at the bottom of the movable water tank 3. Walking motors 6 are provided at both ends of the load-bearing beam 16. The walking motors 6 are drivingly connected to a transfer gearbox 17. The transfer gearbox 17 is drivingly connected to walking wheels 18 that cooperate with the track 5 at the front and back.

[0042] The traveling direction of this device is the same as the strawberry planting direction. The irrigation nozzle 11 extends to the soil at the root of the strawberry. The movable water tank 3 moves along the strawberry planting 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 respectively extend into the fixed water tank 2 and the movable water tank 3. 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. A water injection hole 26 is provided at the top of the central tube 24. A water inlet pipe 29 and a counterweight roller 34 are provided on the side of the T-shaped tube sleeve 25.

[0046] In the above structure, there is an 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 attached Figure 11 and attached Figure 12 As shown, 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 attached Figure 11 and attached Figure 12 As shown, 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. Sliding grooves 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 attached Figure 11 and attached Figure 12 As shown, 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 circle 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 attached Figure 7 、attached Figure 8 、attached Figure 13 、attached Figure 14 、attached Figure 15 and 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 thereof 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 movable 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 to 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 movable 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 movable 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 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 movable water tank 3 connected. By controlling the three-way switching valve 13 to connect the second water injection pipe 15 to the water supply pipe 12, injecting water into the fixed water tank 2 can achieve the replenishment of the movable water tank 3.

[0057] Combined with the attached Figure 17, the 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 is communicated with the second elbow 39, and a regulating valve 9 is communicated at the bottom. The outlet of the regulating valve 9 is communicated with the irrigation pipe 10. A first one-way valve 42 is communicated on the side of the first three-way joint 40. The outlet of the first one-way valve 42 is communicated with the second three-way joint 43. The top of the second three-way joint 43 is communicated with the suction piston cylinder 45, and a second one-way valve 44 is communicated on the side.

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

[0059] Combined with the attached 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 attached 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. Generally speaking, 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 should all fall within the protection scope of the present invention.
