Description

Technical Field

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through holes or drippers on capillary tubes with a diameter of about 10 mm for local irrigation.

[0003] It is the most effective water-saving irrigation method in arid and water-deficient areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 8The present invention provides a technical solution: an automatic regulating drip irrigation device for seedling cultivation, comprising a mounting frame 1, a plurality of connecting columns 4 are arranged on one side of the mounting frame 1, a side connecting frame 5 is fixedly installed on the upper end of the connecting column 4, a plurality of inner sliding seats 13 are slidably connected in the side connecting frame 5, an extension plate 15 is fixedly installed on the inner sliding seat 13, an end of the extension plate 15 away from the inner sliding seat 13 is slidably connected to a limiting member 16, a main connecting pipe 6 is arranged above the side connecting frame 5, a plurality of groups of side branch pipes 7 are fixedly installed on the main connecting pipe 6, a drip irrigation nozzle 8 is arranged on the end of the side branch pipe 7 away from the main connecting pipe 6, and a transmission device is arranged on the drip irrigation nozzle 8 and the limiting member 16, and the transmission device can control the drip irrigation speed of the plurality of groups of drip irrigation nozzles 8 in batches.

[0030] During operation, the seedlings in the present invention are planted in the cultivation bin 2, and both ends of the main connecting pipe 6 are connected to the water source. After planting the seedlings, the user can control the lead-out distance of the limiter 16 on the extension plate 15 by stretching the limiter 16, thereby controlling the longitudinal distance of the drip irrigation nozzle 8 in the cultivation bin 2 (the limiter 16 is slidably connected to the extension plate 15. When the seedling position is far away from the side connecting frame 5, the limiter 16 can be pulled to make the limiter 16 material extension plate 15, and the limiter 16 is moved away from the side connecting frame 5 through the action of the connecting rod 19, so that the drip irrigation pipe is close to the root system of the seedling). In addition, the horizontal position of the drip irrigation pipe on the cultivation pipe can be moved and controlled by the inner sliding seat 13 (when the horizontal position of the drip irrigation nozzle 8 needs to be adjusted, the user turns the adjustment button 26 on the extension plate 15 corresponding to the drip irrigation nozzle 8, The upper bevel gear 25 is driven to rotate by rotating the adjusting knob 26, and the upper bevel gear 25 drives the lower bevel gear 24 to rotate, and the lower bevel gear 24 drives the upper gear 23 to rotate, and the upper gear 23 drives the lower gear 21 to rotate, and the lower gear 21 drives the side threaded member 20 to rotate. The rotation of the side threaded member 20 interacts with the side threaded member 20 to drive the extension plate 15 to move on the side threaded rod 14, and then the inner sliding seat 13 moves on the side connecting frame 5. The movement of the extension plate 15 drives the drip irrigation nozzle 8 to move, and the connecting rod 19 also slides on the linkage rod 17 synchronously while moving), so as to facilitate the precise movement of the drip irrigation pipe to the root position of the seedling, ensure that the drip irrigation water can moisturize the root system of the seedling, and avoid the trouble that the previous drip irrigation setting needs to be assisted by additional positioning equipment (steel wire, etc.) for precise drip irrigation.

[0031] In the present invention, the seedlings are planted in the cultivation chamber 2, and the two ends of the main connecting pipe 6 are connected to the water source. After planting the seedlings, the user can control the lead-out distance of the limit member 16 on the extension plate 15 by stretching the limit member 16, thereby controlling the longitudinal distance of the drip irrigation nozzle 8 in the cultivation chamber 2. In addition, the horizontal position of the drip irrigation pipe on the cultivation pipe can be controlled by moving the inner sliding seat 13, so as to facilitate the precise movement of the drip irrigation pipe to the root position of the seedling, ensure that the drip irrigation water can moisturize the root system of the seedling, and avoid the trouble of the previous drip irrigation setting requiring additional positioning equipment (steel wire, etc.) for precise drip irrigation.

[0032] As a further solution of the present invention, the drip nozzle 8 includes an upper connector 803, the upper end of the upper connector 803 is fixedly connected to the side branch pipe 7, the lower end of the upper connector 803 is fixedly installed with a soft rubber connector 805, the lower end of the soft rubber connector 805 is fixedly installed with an intermediate connector 802, the lower end of the intermediate connector 802 is also fixedly installed with a soft rubber connector 805, the lower end of the lower soft rubber connector 805 is fixedly installed with a lower connector 801, the upper ends of the lower connector 801 and the intermediate connector 802 are fixedly installed with a blocking bucket 804, and the lower end of the upper connector 803 is also fixedly installed with a blocking bucket 804.

[0033] During operation, in the present invention, when it is necessary to control the drip irrigation speed in the drip irrigation nozzle 8, in addition to controlling the large-scale flow rate of the water introduced into the water pipe, the drip irrigation speed can also be controlled more accurately and meticulously by controlling the distance between the three groups of barrier buckets 804. When the drip irrigation speed is required to be the slowest, the connecting rod 19 is separated up and down, the two groups of soft rubber connecting parts 805 are extended, and the barrier buckets 804 are spaced apart up and down. When the water flows out of the drip irrigation pipe, it passes through the three groups of barrier buckets 804 in turn and is slowly output from the lower end of the lower connecting part 801. When the drip irrigation nozzle 8 needs to flow out at a high drip irrigation speed, the connecting rod 19 is driven to be close to each other so that the soft rubber connecting part 805 is folded so that the three groups of barrier buckets 804 are attached together (when the barrier bucket 804 in the middle position needs to move up, the corresponding upper transmission member 29 is driven by the motor to rotate, and the upper transmission member 29 drives the rotating threaded rod 28 to rotate The threaded rod 28 rotates and interacts with the side moving frame 27 to drive the side moving frame 27 to move up. The upward movement of the side moving frame 27 drives the upper linkage rod 17 to move up. The upward movement of the linkage rod 17 drives the connecting rod 19 to move up. The upward movement of the connecting rod 19 drives the middle connection to move up, so that the blocking bucket 804 on the middle connecting member 802 is attached to the lower surface of the upper blocking bucket 804, which slows down the resistance of the water droplets falling. When the drip irrigation speed is further increased, the lower connecting member 801 can be driven to move up by the upper transmission member 29, so that the three groups of blocking buckets 804 are attached together). In this way, the water body is only subjected to one blocking force when falling, the falling speed is faster and the drip irrigation speed is also faster. The drip irrigation speed of each drip irrigation nozzle 8 is uniformly controlled, so as to avoid the problem of inconsistent drip irrigation speeds of different drip irrigation nozzles 8 in the previous method of controlling the drip irrigation speed by controlling the water flow rate.

[0034] In the present invention, when it is necessary to control the drip irrigation speed in the drip irrigation nozzle 8, in addition to controlling the large dimension of the flow rate of the water body introduced into the water pipe, the drip irrigation speed can also be controlled more accurately and meticulously by controlling the distance between the three groups of barrier buckets 804. When the drip irrigation speed is slowest, the connecting rod 19 is separated up and down, the two groups of soft rubber connectors 805 are extended, and the barrier buckets 804 are spaced apart up and down. When the water flows out of the drip irrigation pipe, it passes through the three groups of barrier buckets 804 in sequence and is slowly output from the lower end of the lower connector 801. When the drip irrigation nozzle 8 needs to flow out at a high drip irrigation speed, the connecting rod 19 is driven to be close to each other so that the soft rubber connector 805 is folded so that the three groups of barrier buckets 804 are attached together. In this way, the water body is only subjected to a blocking force once when falling, and the falling speed is faster and the drip irrigation speed is also faster. The drip irrigation speed of each drip irrigation nozzle 8 is uniformly controlled, avoiding the problem of inconsistent drip irrigation speeds of different drip irrigation nozzles 8 in the previous method of controlling the drip irrigation speed by controlling the flow rate of the water body.

[0035] As a further solution of the present invention, the transmission device includes a connecting rod 19 and a linkage rod 17.

The end of the connecting rod 19 away from the drip nozzle 8 is fixedly installed with a limit block 18, and the limit block 18 is slidably connected in the limit member 16.

[0036] During operation, the limit piece 16 is slidably connected to the extension plate 15. When the seedling is far away from the side connecting frame 5, the limit piece 16 can be pulled to make the limit piece 16 extend the plate 15. The limit piece 16 moves away from the side connecting frame 5 through the action of the connecting rod 19, so that the drip irrigation pipe is moved away from the side connecting frame 5, allowing the drip irrigation nozzle 8 to be close to the root system of the seedling.

The rotating threaded rods 28 are respectively threadedly connected to the upper and lower side movable frames 27, and an upper transmission member 29 is arranged between the symmetrically arranged rotating threaded rods 28.

[0038] During operation, when the blocking bucket 804 in the middle position needs to move up, the corresponding upper transmission member 29 is driven by the motor to rotate, and the upper transmission member 29 drives the rotating threaded rod 28 to rotate. The rotating threaded rod 28 rotates and interacts with the side moving frame 27 to drive the side moving frame 27 to move up. The upward movement of the side moving frame 27 drives the upper linkage rod 17 to move up, and the upward movement of the linkage rod 17 drives the connecting rod 19 to move up. The upward movement of the connecting rod 19 drives the middle connection to move up, so that the blocking bucket 804 on the middle connecting member 802 is attached to the lower surface of the upper blocking bucket 804, reducing the resistance to the falling of water droplets. When the drip irrigation speed is further increased, the upper transmission member 29 can be used to drive the lower connecting member 801 to move up, so that the three groups of blocking buckets 804 are attached together.

The upper bevel gear 25 drives the lower bevel gear 24 to rotate, and the lower bevel gear 24 drives the upper gear 23 to rotate. The upper gear 23 drives the lower gear 21 to rotate, and the lower gear 21 drives the side threaded member 20 to rotate. The rotation of the side threaded member 20 interacts with the side threaded member 20 to drive the extension plate 15 to move on the side threaded rod 14, and then the inner sliding seat 13 moves on the side connecting frame 5. The movement of the extension plate 15 drives the drip irrigation nozzle 8 to move, and the connecting rod 19 also slides on the linkage rod 17 synchronously while moving.
