Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of planting greenhouses, and particularly relates to a netted shed for cultivation of crisp honey kumquats and a control method thereof. BACKGROUND

[0002] Nowadays, many fruit plants need to be built with sunshading sheds or insect-proof netted sheds. For example, a patent document with the announcement number CN105093983A discloses a netted shed for disease-free seedling cultivation of Wohu and Maoqu oranges. The netted shed comprises a netted shed body, a sunshade device arranged above the netted shed body, the sunshade device comprising a support arranged above the netted shed body, an insect-proof net arranged on the support, and a sunshade net control device for controlling the opening and closing of the insect-proof net. The netted shed body is internally arranged with seedling cultivation racks, the seedling cultivation racks comprising legs, net plates arranged on the legs, and guardrails arranged on both sides of the net plates. The seedling cultivation racks are arranged on the soil, and a water spraying system is arranged above the seedling cultivation racks. The arrangement of the sunshade device and the seedling cultivation racks can improve the survival rate of Wohu and Maoqu orange seedlings, reduce the occurrence of soil-borne diseases, reduce the use of insecticides, and is conducive to the growth of seedlings. In addition, the transplanting operation is convenient, which is conducive to improving work efficiency and reducing labor costs.

[0003] The cultivation of crisp honey kumquats is different from that of ordinary oranges. Before the ripening of crisp honey kumquats, an insect-proof netted shed needs to be built, and a rain-proof shed needs to be built during the ripening period. Because the skin of crisp honey kumquats is relatively thin, rainwater needs to be avoided to prevent the occurrence of cracked fruits and affect the quality. However, the existing cultivation shed has the problem that the insect-proof net and the rain-proof cloth are difficult to switch with each other, that is, the replacement of the insect-proof net and the rain-proof cloth of the cultivation shed wastes a large amount of manpower and has a high cost, especially when the cultivation area is large and the area of the insect-proof net or the rain-proof cloth used is large, it is difficult to install and replace the insect-proof net or the rain-proof cloth on the shed frame. SUMMARY

[0004] The present application aims to solve the problem of the existing cultivation shed that the insect-proof net and the rain-proof cloth are difficult to switch with each other, and proposes a netted shed for cultivation of crisp honey kumquats and a control method thereof.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A netted shed for cultivation of crisp honey kumquats, comprising a shed body support structure and a protective layer, the shed body support structure comprising a plurality of main support frames and a plurality of auxiliary support frames, the main support frame comprising two support columns and an arch-shaped frame, the bottom ends of the two support columns being fixed to the ground, the two ends of the arch-shaped frame being fixedly connected to the top ends of the support columns, and a mounting beam being slidably installed on the upper side of the arch-shaped frame, the protective layer being covered on the upper side of the main support frame and being fixedly connected with the mounting beam.

[0007] The auxiliary support frame includes a U-shaped bracket and an arched slide rail. The arched slide rail is fixedly connected to the upper end of the U-shaped bracket to form a ring structure. The U-shaped bracket has a sliding channel inside, and a flexible telescopic chain is slidably installed in the sliding channel. A first valve and a second valve are fixedly installed at both ends of the U-shaped bracket, and the first valve and the second valve control the opening and closing of both ends of the sliding channel, respectively.

[0008] The inner side of the U-shaped bracket is fixedly installed with a first pipe and a second pipe, which are respectively connected to the two ends of the sliding channel. When pressurized fluid is injected into the first pipe or the second pipe, the internal pressure of the sliding channel increases, which pushes the telescopic chain to extend from the first valve or the second valve. The telescopic chain moves along the contour of the arched slide rail, and the end of the telescopic chain abuts against the mounting beam, pushing the mounting beam to move along the arched frame, thereby driving the protective layer to move, which facilitates the replacement of the protective layer and reduces the burden of manual replacement of the protective layer.

[0009] Preferably, the telescopic chain includes a first link, a second link, and a magnetic ball. The first link, the second link, and the magnetic ball are rotatably connected to each other to form a unit chain. Multiple unit chains are rotatably connected to each other and connected in series to form a telescopic chain with the first link and the second link at each end. The telescopic chain has one end support.

[0010] Preferably, the magnetic ball has right-angle grooves symmetrically formed at its upper and lower ends, and connecting shafts are fixedly installed in the right-angle grooves on the upper and lower sides respectively. The top end of the first link is rotatably connected to the connecting shaft in the lower right-angle groove, and the bottom end of the second link is rotatably connected to the connecting shaft in the upper right-angle groove. A side positioning plate is fixedly installed on the side of the first link. After the first link and the second link are rotatably connected, the second link is blocked by the side positioning plate, so that the first link or the second link can only be flipped to one side. The outer surface of the magnetic ball is provided with a rubber coating layer, and the outer surface of the rubber coating layer slides in contact with the inner wall of the sliding channel, so that the telescopic chain can be bent and move along the sliding channel in the U-shaped bracket.

[0011] Preferably, a first roller and a second roller are rotatably mounted on the lower side of the mounting beam. The first roller and the second roller roll along the upper and lower surfaces of the arched frame, respectively. A concave groove is opened on the upper surface of the arched slide rail. The magnetic ball attracts the arched slide rail and slides along the inner wall of the concave groove.

[0012] Preferably, the protective layer includes an insect-proof net and a rainproof cloth, which are respectively laid on both sides of the mounting beam, and both the insect-proof net and the rainproof cloth are fixedly connected to the upper surface of the mounting beam.

[0013] Preferably, a connecting sleeve is slidably installed on the surface of the supporting column, and a fixing bolt is threaded on the surface of the connecting sleeve. The connecting sleeve is fixedly connected to the supporting column by the fixing bolt. Storage boxes are provided on both sides of the shed support structure. The storage boxes are fixedly connected to the connecting sleeve. A flip-up box door is hinged on the outside of the storage box. The lower edges of the insect-proof net and the rainproof cloth can be folded and placed in the storage boxes on both sides respectively. Multiple lifting rings are threaded on the upper side of the storage box.

[0014] Preferably, multiple irrigation pipes are fixedly installed on the surface of both the first and second pipes, and a third valve is fixedly installed at the opening of each irrigation pipe. When the third valve is opened, water can be drawn from the irrigation pipe for irrigation.

[0015] The present invention has the following beneficial effects:

[0016] 1. This net shed, by setting up a protective layer consisting of half insect-proof netting and half rain-proof cloth, uses the left and right movement of the installation beam to pull the insect-proof netting or rain-proof cloth to cover the upper side of the shed support structure, meeting the needs of insect-proof protection or rain protection at different fruit stages, reducing the workload of manually switching insect-proof netting or rain-proof cloth, and making it more convenient to use.

[0017] 2. This net shed, by setting up a secondary support frame and installing telescopic chains inside it, uses water pressure to provide power for the movement of the telescopic chains, thereby pushing the installation beam to move left and right. This design allows the number of telescopic chains to be increased or decreased according to the size of the net shed. Using more telescopic chains to push the installation beam to move can ensure that the installation beam is evenly stressed, avoid the installation beam from tilting and jamming, and ensure its safe and reliable operation.

[0018] Using a telescopic chain to move the installation beam to replace the protective layer is faster than using a roller to roll up the protective layer. Moreover, the roller rolls are rolled up from one end, which applies a greater pulling force to the protective layer and may cause damage to the insect net or rain cover.

[0019] Compared to using ropes to pull and install beams, whether the ropes are slidably connected to the netting frame or connected through the guide wheels of the netting frame, the tension force of the ropes is transmitted to the netting frame when pulling the ropes, which can cause the netting frame to deform or break, or require the netting frame to be more rigid, increasing costs. Using telescopic chains reduces the pressure on the netting frame and can effectively protect the stability of the netting.

[0020] 3. This net shed, by setting up a first pipe and a second pipe, can transport water to power the movement of the telescopic chain or for irrigation, and can also transport pesticides for mist spraying to kill insects. This design simplifies the structure of the net shed, greatly reduces the construction cost, and meets the conditions for wide market application. Attached Figure Description

[0032] Example 1

[0033] Reference Figures 1-8 A netted greenhouse for cultivating crisp honey kumquats includes a greenhouse support structure and a protective layer. The greenhouse support structure includes multiple main support frames 1 and multiple secondary support frames 2. The main support frame 1 includes two support columns 3 and an arched frame 4. The bottom ends of the two support columns 3 are fixed to the ground. The two ends of the arched frame 4 are fixedly connected to the top ends of the support columns 3. An installation beam 5 is slidably installed on the upper side of the arched frame 4. A first roller 19 and a second roller 20 are rotatably installed on the lower side of the installation beam 5. The first roller 19 and the second roller 20 roll along the upper and lower surfaces of the arched frame 4, respectively. A concave groove is opened on the upper surface of the arched slide rail 7. A magnetic ball 16 attracts the arched slide rail 7 and slides along the inner wall of the concave groove.

[0034] The protective layer covers the upper side of the main support frame 1 and is fixed together with the mounting beam 5.

[0035] The secondary support frame 2 includes a U-shaped bracket 6 and an arched slide rail 7. The arched slide rail 7 is fixedly connected to the upper end of the U-shaped bracket 6 to form a ring structure. The lower side of the U-shaped bracket 6 is buried underground. A sliding channel 8 is opened inside the U-shaped bracket 6, and a flexible telescopic chain 9 is slidably installed in the sliding channel 8. A first valve 10 and a second valve 11 are fixedly installed at both ends of the U-shaped bracket 6, respectively. The first valve 10 and the second valve 11 control the opening and closing of both ends of the sliding channel 8.

[0036] The first pipe 12 and the second pipe 13 are fixedly installed on the inner side of the U-shaped bracket 6. The first pipe 12 and the second pipe 13 are respectively connected to the two ends of the sliding channel 8. When pressurized fluid is injected into the first pipe 12 or the second pipe 13, the internal pressure of the sliding channel 8 increases, which pushes the telescopic chain 9 to extend from the first valve 10 or the second valve 11. The telescopic chain 9 moves along the contour of the arched slide rail 7, and the end of the telescopic chain 9 presses against the mounting beam 5, pushing the mounting beam 5 to move along the arched frame 4. Under normal conditions, the first valve 10 and the second valve 11 are closed, and the telescopic chain 9 is stored in the sliding channel 8.

[0037] In this embodiment, as Figure 6 As shown, the telescopic chain 9 includes a first link 14, a second link 15, and a magnetic ball 16. The first link 14, the second link 15, and the magnetic ball 16 are rotatably connected to each other to form a unit chain. Multiple unit chains are rotatably connected to each other and connected in series to form a telescopic chain 9 with the first link 14 and the second link 15 at each end.

[0038] The magnetic ball 16 has symmetrical right-angle grooves 17 at its upper and lower ends, and connecting shafts are fixedly installed in the right-angle grooves 17 on the upper and lower sides respectively. The top end of the first link 14 is rotatably connected to the connecting shaft in the lower right-angle groove 17, and the bottom end of the second link 15 is rotatably connected to the connecting shaft in the upper right-angle groove 17. A side positioning plate 18 is fixedly installed on the side of the first link 14. After the first link 14 and the second link 15 are rotatably connected, the second link 15 is blocked by the side positioning plate 18, so that the first link 14 or the second link 15 can only be flipped to one side. That is, the telescopic chain 9 can be bent and move along the sliding channel 8 in the U-shaped bracket 6. (Reference) Figure 7 .

[0039] The outer surface of the magnetic ball 16 is provided with a rubber coating layer, and the outer surface of the rubber coating layer slides in contact with the inner wall of the sliding channel 8, such as... Figure 5 As shown.

[0040] The protective layer includes an insect-proof net 21 and a rain-proof cloth 22. The mounting beam 5 slides along the arched frame 4 to lower the height of the mounting beam 5. The insect-proof net 21 or the rain-proof cloth 22 can be installed separately on the mounting beam 5. Finally, the insect-proof net 21 or the rain-proof cloth 22 is covered on the shed support structure.

[0041] In this embodiment, taking a protective layer consisting of half insect-proof netting 21 and half rain-proof cloth 22 as an example, the insect-proof netting 21 and the rain-proof cloth 22 are respectively laid on both sides of the mounting beam 5, and both the insect-proof netting 21 and the rain-proof cloth 22 are fixedly connected to the upper surface of the mounting beam 5. (Refer to...) Figure 1 .

[0042] Example 2

[0043] Reference Figures 1-8 Unlike Embodiment 1, a connecting sleeve is slidably installed on the surface of the supporting column 3, and a fixing bolt 23 is threaded on the surface of the connecting sleeve. The connecting sleeve is fixedly connected to the supporting column 3 by the fixing bolt 23. Storage boxes 24 are provided on both sides of the shed support structure. The storage boxes 24 are fixedly connected to the connecting sleeve. A flip-up box door is hinged on the outside of the storage box 24. The lower edges of the insect net 21 and the rain cover 22 can be folded and placed in the storage boxes 24 on both sides respectively. Multiple hanging rings 25 are threaded on the upper side of the storage box 24.

[0044] In this embodiment, multiple irrigation pipes 26 are fixedly installed on the surface of the first pipe 12 and the second pipe 13. A third valve 27 is fixedly installed at the mouth of the irrigation pipe 26. A sprinkler system can be built inside the net shed. The irrigation pipes 26 are connected to the sprinkler system and can be used for irrigation of the orchard or for mist spraying to avoid damage from various migratory pests such as fruit flies, stink bugs, moths, locusts, and birds.

[0045] By setting up the first pipe 12 and the second pipe 13, high-pressure water can be transported in the pipes to provide power for the movement of the telescopic chain 9, or it can be used for irrigation. The pipes can also be used to transport pesticides for mist spraying to kill insects. This design simplifies the structure of the net shed and greatly reduces the construction cost.

[0046] The method for controlling the netted greenhouse used in the cultivation of Crispy Honey Kumquats includes the following specific steps:

[0047] 1) Driving the telescopic chain 9: Open the first valve 10 and close the second valve 11. High-pressure water is injected into the sliding channel 8 through the second pipe 13. The water flow pushes the telescopic chain 9 inside to extend out from the first valve 10 and move along the contour of the arched slide rail 7. The end of the telescopic chain 9 presses against the mounting beam 5, pushing the mounting beam 5 to move along the arched frame 4. Water is pumped into the second pipe 13 and flows into the sliding channel 8 through the first pipe 12, and the telescopic chain 9 is sucked into the sliding channel 8.

[0048] Open the second valve 11 and close the first valve 10. High-pressure water is injected into the sliding channel 8 through the first pipe 12. The water flow pushes the internal telescopic chain 9 to extend from the second valve 11 and move along the contour of the arched slide rail 7. The end of the telescopic chain 9 presses against the mounting beam 5, pushing the mounting beam 5 to move along the arched frame 4. Water in the first pipe 12 is pumped in and flows into the sliding channel 8 through the second pipe 13, and the telescopic chain 9 is sucked into the sliding channel 8.

[0049] 2) Switching between the insect-proof net 21 and the rain cover 22 on the upper side of the shed support structure: Use the telescopic chain 9 to push the installation beam 5 to move towards the second pipe 13. The installation beam 5 pulls the insect-proof net 21 to cover the shed support structure, and at the same time, pushes down the rain cover 22.

[0050] Using the telescopic chain 9, the installation beam 5 is pushed to move towards the first pipe 12. The installation beam 5 pulls the rain cover 22 to cover the shed support structure, and at the same time, the insect net 21 is pushed down.

[0051] 3) Adjustment of ventilation in the lower space of the net shed: Loosen the fixing bolt 23, connect the end of the telescopic chain 9 to the hanging ring 25 with the connecting rope, and use the telescopic chain 9 to lift the storage box 24 to a certain height. Then tighten the fixing bolt 23, and keep the storage box 24 at a certain distance from the ground to facilitate the passage of natural wind through the lower side of the net shed.

[0052] By setting up a secondary support frame 2 and installing telescopic chains 9 inside it, water pressure is used to power the movement of the telescopic chains 9. The telescopic chains 9 push the installation beam 5 to move left and right. This design allows the number of telescopic chains 9 to be increased or decreased according to the size of the net shed. Using more telescopic chains 9 to push the installation beam 5 to move can ensure that the installation beam 5 is subjected to uniform force, avoid the installation beam 5 from tilting and jamming, and ensure its safe and reliable operation.

[0053] Using the telescopic chain 9 to move the installation beam 5 to replace the protective layer is faster than using a roller to roll up the protective layer. Moreover, the roller rolls up the protective layer at one end, which applies a greater pulling force to the protective layer and may cause damage to the insect net 21 or the rain cover 22.

[0054] Compared to using ropes to pull the beam 5, whether the rope is slidably connected to the net frame or connected through guide wheels on the net frame, the tension force of the rope is transmitted to the net frame when pulling the rope, which can cause the net frame to deform or break, or require the net frame to be more rigid, increasing costs. However, using telescopic chains 9 reduces the pressure on the net frame and can effectively protect the stability of the net.

[0055] refer to Figure 7 F1 is the thrust of the telescopic chain 9 on the installation beam 5, F2 is the resistance of the protective layer, and F3 is the gravity of the protective layer and the installation beam 5. The resultant forces of F1, F2, and F3 are opposite in direction, with F1 tilting upward to reduce the pressure on the shed support structure when replacing the protective layer.

[0056] The net shed is equipped with a protective layer consisting of half insect-proof netting 21 and half rain-proof cloth 22. By moving the installation beam 5 left and right, the insect-proof netting 21 or rain-proof cloth 22 can be pulled to cover the upper side of the shed support structure, which can meet the needs of insect protection or rain protection at different fruit stages, reduce the workload of manually switching insect-proof netting 21 or rain-proof cloth 22, and make it more convenient to use.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
