Description

Technical Field

[0001] This invention belongs to the field of sprinkler irrigation technology, specifically relating to a water-saving irrigation device and irrigation method for chrysanthemum cultivation. Background Technology

[0002] Chrysanthemums are found in towns and rural areas throughout China. In order to ensure the normal growth of chrysanthemums, they need to be sprayed and irrigated during the planting process.

[0003] A search revealed a high-efficiency sprinkler irrigation device for chrysanthemum cultivation, with authorization number CN216601401U. The device includes a handcart, a medicine storage tank fixedly installed on the upper surface of the handcart, a water inlet connected to the outer surface of the medicine storage tank, a water pump connected to the outer surface of the medicine storage tank, a hose connected to the outlet of the water pump, and a water pipe fixedly installed at the end of the hose away from the water pump.

[0004] This invention, by setting up a handcart, medicine storage tank, water inlet, water pump, hose, water pipe, nozzle, rotating frame, handle, guide plate, fixing plate, fixing block and sliding rod, realizes the function of adjusting the direction of spray irrigation. By changing the direction of the nozzle, the operator can change the irrigation direction without moving the entire spray irrigation device.

[0005] However, the above-mentioned device still has the following problems: when spraying and irrigating chrysanthemums, the device cannot adjust the amount of water sprayed according to the area of ​​the flower bed. Excessive water spraying will not only waste water resources, but also cause the chrysanthemums to wilt. Insufficient water spraying will cause the roots of the chrysanthemums to dry out, and in severe cases, it will cause the chrysanthemums to die. Summary of the Invention

[0006] To address the problems existing in the prior art, a water-saving irrigation device and irrigation method for chrysanthemum cultivation are provided.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] This technical solution proposes a water-saving irrigation device for chrysanthemum cultivation, including a water tank, a nozzle sealed to the water tank, a fixed cylinder fixedly connected to the water tank, the fixed cylinder fixedly connected to the nozzle, an outer pressure ring slidably connected inside the nozzle, the outer pressure ring having a cavity, a middle pressure ring slidably connected inside the cavity, the middle pressure ring and the outer pressure ring being used to adjust the water spray volume of the nozzle, and a first sliding cylinder slidably connected to the fixed cylinder;

[0009] It also includes a drive mechanism, which is disposed on the fixed cylinder and is used to drive the first sliding cylinder to slide in the horizontal direction.

[0010] Preferably, the drive mechanism includes a handwheel, which is engaged with a first gear, and the first slide is fixedly connected to a second rack, which meshes with the first gear.

[0011] Preferably, it further includes a sliding shaft, which is fixedly connected to the intermediate pressure ring and slidably connected to the first slide cylinder.

[0012] Preferably, the top of the sliding shaft is fixedly connected to a plurality of horizontally arranged first inclined plates, the bottom of the first inclined plates is inclined, the first sliding cylinder is fixedly connected to a protrusion, and the first inclined plates and the protrusions are slidably engaged.

[0013] Preferably, a first inclined plate is fixedly connected to a second inclined plate, and a sliding shaft is fixedly connected to a pressure block, wherein the pressure block is slidably engaged with the second inclined plate.

[0014] Preferably, the first slide cylinder is slidably connected to a second slide cylinder, and the second slide cylinder is fixedly connected to a first rack.

[0015] Preferably, the handwheel is engaged with a second gear, and the first rack meshes with the second gear.

[0016] Preferably, a first spring is connected between the outer pressure ring and the nozzle, and the first spring is used to drive the outer pressure ring to reset.

[0017] Preferably, a tube is fixedly connected to the bottom of the sliding shaft, the tube is slidably connected to the nozzle, and the tube has a water inlet hole for transporting water into the nozzle.

[0018] The present invention also proposes an irrigation method using the above-mentioned water-saving irrigation device for chrysanthemum cultivation, comprising the following steps:

[0019] S1: Adjust the water volume according to the chrysanthemum planting area. Turn the handwheel, the handwheel drives the first gear to rotate, the first gear drives the second rack to move, the second rack drives the first slide cylinder to move, and then drives the nozzle to move, thereby completing the adjustment of the spraying area.

[0020] S2: When the nozzle moves, it will drive the sliding shaft to move, which in turn drives the first inclined plate to move. The first inclined plate will move upward under the action of the protrusion, which in turn drives the sliding shaft to move upward, which in turn drives the pipe to move upward. The pipe drives the medium pressure ring to move upward, thereby opening part of the spray nozzle on the nozzle and increasing the spraying area.

[0021] S3: When it is necessary to increase the irrigation spray volume, the first sliding cylinder continues to move, and under the action of the protrusion, the first inclined plate continues to drive the medium pressure ring to continue to move upward. At this time, the medium pressure ring will drive the outer pressure ring to continue to move upward, opening all the spray nozzles on the sprinkler head, and the spray volume reaches the maximum, completing the full irrigation of the chrysanthemum.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. This invention can move the first and second inclined plates when the first and second sliding cylinders move, thereby moving the sliding axis upward, which in turn moves the middle pressure ring and the outer pressure ring upward. As the moving distance of the nozzle increases, more water nozzles are opened, resulting in a larger spray area and a larger water volume. When the chrysanthemum planting area is small, a small number of water nozzles can be opened to save water. When the chrysanthemum planting area is large, all water nozzles can be opened to increase the spray area. This improves irrigation efficiency and saves water resources to a certain extent, reduces costs, and is highly practical.

[0024] 2. In this invention, the first and second sliding cylinders are moved by rotating the handwheel, thereby adjusting the distance between the nozzles. The nozzles can be adjusted to the appropriate position according to the size of the chrysanthemum nursery, which can effectively irrigate large areas of chrysanthemum planting sites in all directions, improving irrigation efficiency, reducing the labor intensity of operators, and saving operators' time and energy.

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1-7 As shown, this embodiment proposes a water-saving irrigation device for chrysanthemum cultivation, including a water tank 18, a water pump 17 fixedly connected to the water tank 18, a water distribution block 16 sealed to the water pump 17 via a water pipe, a fixed cylinder 24 fixedly connected to the water tank 18, the fixed cylinder 24 and the water distribution block 16 connected via a flexible hose, a nozzle 2 fixedly connected to the fixed cylinder 24, the nozzle 2 being machined with spray nozzles of different angles, namely a first spray nozzle 203, a second spray nozzle 202 and a third spray nozzle 201, an outer pressure ring 20 slidably connected inside the nozzle 2, the outer pressure ring 20 having openings... The cavity contains a slidably connected intermediate pressure ring 26, which is connected to the nozzle 2 via a second spring 25. The intermediate pressure ring 26 is used to compact the second water nozzle 202 and the first water nozzle 201. The outer pressure ring 20 is used to compact the third water nozzle 201. The cavity also includes a drive mechanism, which includes a handwheel 12. The handwheel 12 is engaged with a first gear 8 and is used to drive the first gear 8 to rotate. The fixed cylinder 24 is slidably connected to a first slide cylinder 6, which is fixedly connected to a second rack 19. The second rack 19 is engaged with the first gear 8.

[0037] Handwheel 12 is fixedly connected to a first conical wheel 13, which meshes with a disc gear 11. Disc gear 11 is fixedly connected to a rotating shaft 14, which is fixedly fitted with several disc gears 11. Disc gears 11 mesh with a second conical wheel 9, which is fixedly connected to a first gear 8. When handwheel 12 is turned, the first conical wheel 13 is driven to rotate, which in turn causes the disc gears 11 meshing with the first conical wheel 13 to rotate. Disc gears 11 drive the second conical wheel 9 to rotate, which in turn causes the first gear 8 to rotate. This causes the second rack 19 of the first gear 8 to move, thus moving the first slide cylinder 6 under the drive of the second rack 19. At this time, water pump 17 is started, which drives irrigation water into the sprinkler head 2, thereby irrigating more chrysanthemums, saving manpower and resources, and improving irrigation efficiency.

[0038] It also includes a sliding shaft 22, which is fixedly connected to the intermediate pressure ring 26 and slidably connected to the first sliding cylinder 6. Several horizontally arranged first inclined plates 5 are fixedly connected to the top of the sliding shaft 22. The bottom of the first inclined plates 5 is inclined. The first sliding cylinder 6 is fixedly connected to a protrusion 15. The first inclined plates 5 and the protrusion 15 are slidably engaged. When the first sliding cylinder 6 moves, it will drive the first inclined plates 5 to move. Since the bottom of the first inclined plates 5 is inclined, when the first inclined plates 5 are moved, the first inclined plates 5 will be pushed up by the protrusion 15, which will drive the sliding shaft 22 to move upward, thereby causing the intermediate pressure ring 26 to move upward, canceling the compaction of the second water nozzle 202 and the first water nozzle 203, so that irrigation water flows out from the second water nozzle 202 and the first water nozzle 203.

[0039] When the chrysanthemum flower bed area is larger and the water volume needs to be increased, the first sliding cylinder 6 continues to move, and the first inclined plate 5 continues to drive the sliding shaft 22 to rise, thereby causing the intermediate pressure ring 26 to drive the outer pressure ring 20 to continue to move upward. As a result, the outer pressure ring cancels the compaction of the third spray nozzle 201, so that the water output of the nozzle 2 is greater, and a larger area can be irrigated. While saving water, the water volume can also be adjusted according to needs, saving the physical strength of the staff and improving work efficiency.

[0040] One of the first inclined plates 5 is fixedly connected to a second inclined plate 10. The upper end of the second inclined plate 10 is inclined. One of the sliding shafts 22 is fixedly connected to a pressure block 23. The pressure block 23 slides with the second inclined plate 10. When the first inclined plate 5 moves, it will drive the second inclined plate 10 to move. Then the second inclined plate 10 will lift the pressure block 23. The pressure block 23 will drive the sliding shaft 22 of the fixed cylinder 24 to move upward, which will drive the middle pressure ring 26 and the outer pressure ring 20 to move upward, opening the restriction on the water spray hole in the nozzle 2 and increasing the water spray volume.

[0041] The first slide cylinder 6 is slidably connected to the second slide cylinder 3, and the second slide cylinder 3 is fixedly connected to the first rack 4. The handwheel 12 is engaged with the second gear 1. The first rack 4 and the second gear 1 mesh. When it is necessary to increase the spraying area, the rotating shaft 4 will drive the disc gear 11 to rotate. The disc gear 11 will drive the second conical wheel 9 to rotate. The second conical wheel 9 will drive the second gear 1 to rotate, thereby driving the first rack 4 to move, and then driving the second slide cylinder 3 to move, thus realizing the movement of the nozzle 2 and increasing the spraying area.

[0042] A first spring 21 is connected between the outer pressure ring 20 and the nozzle 2. The first spring 21 is used to drive the outer pressure ring 20 to reset. After the watering is completed, the handwheel 12 can be turned to reset the first slide 6 and the second slide 3. At this time, the middle pressure ring 26 will reset under the action of the second spring 25, and the outer pressure ring 20 will reset under the action of the first spring 21, thus completing the compaction of the water spray hole.

[0043] The bottom of the sliding shaft 22 is fixedly connected to the tube 27, which is slidably connected to the nozzle 2. The tube 27 has a water inlet hole for transporting water into the nozzle 2. When the chrysanthemum flower bed needs to be irrigated, the water will flow into the nozzle through the water inlet hole and then flow out through the spray hole.

[0044] Both the first rack 4 and the second rack 19 are fixedly connected to a stop block, which can limit the first rack 4 and the second rack 19, thus ensuring the reliability of the device.

[0045] The water divider 16 is connected to a connector 7 via a hose. The connector 7 is sealed to the fixed cylinder 24. The water divider 16 can divide the water in the water tank 18 into different pipelines, thereby increasing the spraying area.

[0046] The water tank 18 is also equipped with wheels, which can be used to move the water tank 18 when needed, reducing the waste of manpower and material resources and improving work efficiency.

[0047] This invention also proposes an irrigation method, employing a water-saving irrigation device for chrysanthemum cultivation as described in this embodiment, comprising the following steps:

[0048] S1: Adjust the water volume according to the chrysanthemum planting area. Turn the handwheel 12. The handwheel 12 drives the first gear 8 to rotate. The first gear 8 drives the second rack 19 to move. The second rack 19 drives the first slide cylinder 6 to move, which in turn drives the nozzle 2 to move, thereby completing the adjustment of the spraying area.

[0049] S2: When the nozzle 2 moves, it will drive the sliding shaft 22 to move, thereby driving the first inclined plate 5 to move. The first inclined plate 5 will move upward under the action of the protrusion 15, and then the first inclined plate 5 will drive the sliding shaft 22 to move upward, thereby driving the pipe 27 to move upward. The pipe 27 will drive the medium pressure ring 26 to move upward, thereby opening part of the spray nozzle on the nozzle 2 and increasing the spraying area.

[0050] S3: When it is necessary to increase the irrigation spray volume, the first sliding cylinder 6 continues to move, so that under the action of the protrusion 15, the first inclined plate 5 continues to drive the medium pressure ring 26 to continue to move upward. At this time, the medium pressure ring 26 will drive the outer pressure ring 20 to continue to move upward, opening all the spray nozzles on the nozzle 2, and the spray volume reaches the maximum, completing the full irrigation of the chrysanthemum.

[0051] It should be noted that when watering chrysanthemums, the water volume needs to be adjusted according to the different planting areas. The operator pushes the device into the area requiring watering and adjusts the water flow from the spray nozzles according to the size of the chrysanthemum planting area. Then, turning handwheel 12 rotates the first conical wheel 13, which in turn rotates the disc gear 11. The disc gear 11 rotates the rotating shaft 14, which in turn rotates all the disc gears 11 on the shaft. The disc gears 11 then rotate the second conical wheel 9, which in turn rotates the first gear 8. The first gear 8 then moves the second rack 19, which in turn moves the first sliding cylinder 6, thereby moving the nozzle 2.

[0052] Additionally, at this time, the nozzle 2 drives the sliding shaft 22 to move, the sliding shaft 22 drives the first inclined plate 5 to move, the first inclined plate 5 moves upward under the action of the protrusion 15, and at the same time the first inclined plate 5 drives the sliding shaft 22 to slide upward. At this time, the sliding shaft 22 drives the tube 27 to move upward, and then drives the intermediate pressure ring 26 to move, so that the intermediate pressure ring 26 leaves the second water spray hole 202, and the water spray area increases. At this time, the first sliding tube 6 continues to move, the intermediate pressure ring 26 continues to move, so that the outer pressure ring 20 moves upward, so that the outer pressure ring 20 leaves the third water spray hole 201, and the water spray area continues to increase.

[0053] Furthermore, since the first gear 8 and the second gear 1 rotate at different speeds, when the handwheel 12 is turned, the disc gear 11 continues to rotate, thereby driving the second conical wheel 9 to rotate, which in turn drives the second gear 1 to rotate. The second gear 1 drives the first rack 4 to move, the first rack 4 drives the second slide cylinder 3 to move, which in turn drives the nozzle 2 to move. At this time, the nozzle 2 drives the sliding shaft 22 to move, the sliding shaft 22 drives the first inclined plate 5 to move, and the first inclined plate 5 moves upward under the action of the protrusion 15. At this time, the first inclined plate 5 will drive the second inclined plate 10 to move upward, the second inclined plate 10 will drive the pressure block 23 to move upward, and the pressure block 23 will drive the sliding shaft 22 to slide upward. At this time, the sliding shaft 22 drives the tube 27 to move upward, which in turn drives the intermediate pressure ring 26 to move, thereby causing the intermediate pressure ring 26 to leave the second water spray hole 202, increasing the water spray area.

[0054] In addition, as the first slide cylinder 6 and the second slide cylinder 3 move, the distance between several nozzles 2 increases, thereby increasing the spraying area and the amount of water sprayed, which is suitable for the irrigation requirements of different stages of chrysanthemum growth and is also suitable for different chrysanthemum planting areas. It saves manpower, material resources and water, and is highly practical. After irrigation is completed, the handwheel 12 is turned in the opposite direction, and the first slide cylinder 6 and the second slide cylinder 3 will move towards the center of the water tank 18. Then, under the action of the first spring 21 and the second spring 25, the middle pressure ring 26 and the outer pressure ring 20 are pulled to reset. After the reset is completed, the operator can transport the water tank 18 to the next location that needs to be irrigated, and wait for the next irrigation.

[0055] As can be seen from the above, the present invention is ingeniously designed, employing a mechanical structure that makes the device easier and more convenient to operate. The simple and ingenious structure allows for adjustment of the spray volume according to different situations, achieving water conservation while also fully irrigating the chrysanthemums.

[0056] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
