Technical Field

[0001] The utility model relates to the technical field of potato seedling raising, in particular to an improved structure of a greenhouse sprinkler irrigation machine for potato bottle seedling planting. Background Art

[0002] After potato bottle seedlings are acclimatized, they need to be planted on a movable seedbed; during planting, workers use tweezers to take out the seedlings in the culture bottle, wash the culture medium on the roots in clean water, and then plant them on the substrate of the movable seedbed. After the seedbed is full, a watering can needs to be used to sprinkle water in a thin stream (the watering can referred to here is not an ordinary pressure watering can, but a hand-held watering can that sprays water based on gravity), so that the seedlings and the substrate can be fully healed. After culturing for a certain period of time, it is transferred to routine management.

[0003] In existing greenhouses, a greenhouse sprinkler irrigation machine is usually used for subsequent irrigation of potato seedlings. The greenhouse sprinkler irrigation machine can reciprocate along the length direction of the movable seedbed. Structurally, the greenhouse sprinkler irrigation machine includes a movable frame driven by a motor to move, and a water supply pipeline arranged on the movable frame to supply water to the nozzles; generally, the positions of the nozzles of the existing greenhouse sprinkler irrigation machine are fixedly installed, and the spacing between its multiple nozzles is fixed, which is not convenient for adjustment; for the different planting spacings of potato seedlings during planting or the layout of the movable seedbed may be adjusted according to actual production needs, and the sprinkler irrigation machine with fixed nozzle spacing cannot well adapt to this change. In addition, the existing methods for adjusting the nozzle spacing are often more cumbersome, and may require large-scale disassembly and reassembly of the equipment, which not only consumes a lot of time and manpower, but also may damage the equipment and increase the maintenance cost.

It is characterized in that it further includes a variable-spacing mechanism arranged on the transverse conveying pipe; the variable-spacing mechanism includes a frame body connected to both ends of the transverse conveying pipe, a driving component arranged on the frame body, and a plurality of moving rods connected to the driving component; the driving component drives the plurality of moving rods to approach or move away synchronously, and the plurality of nozzles are arranged in one-to-one correspondence with the plurality of moving rods, and the nozzles are connected to the moving rods.

[0006] Further, the driving assembly includes an electric push rod vertically arranged on the frame body, a variable pitch adjusting plate connected to the output shaft of the electric push rod, and two guide rods horizontally arranged on the frame body; the variable pitch adjusting plate is slidably matched with the frame body, a plurality of fan-shaped distribution chutes are arranged on the variable pitch adjusting plate, sliders adapted to the chutes are arranged on the moving rod, the sliders are slidably matched with the chutes, and a plurality of the moving rods are all horizontally slidably matched with the two guide rods.

[0007] Further, the moving rod is L-shaped, the vertical end of the moving rod is slidably matched with the two guide rods, and the horizontal end of the moving rod is connected to the nozzle.

[0008] Further, a storage battery connected to the electric push rod is arranged on the frame body.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] The electric push rod drives the variable pitch adjusting plate to move up and down, and when the variable pitch adjusting plate moves, a plurality of moving rods connected and matched with it are driven to approach or move away from each other through a plurality of chutes arranged on the variable pitch adjusting plate, so as to realize the adjustment of the spacing between a plurality of nozzles; the device realizes the adjustment of the spacing between a plurality of nozzles by setting a variable pitch mechanism connected to a plurality of nozzles, so as to adjust the spacing between a plurality of nozzles when the planting spacing of potato seedlings is different during planting or the layout of the movable seedbed needs to be adjusted according to actual production needs, and the device can complete the adjustment only through the variable pitch adjusting plate that moves up and down, which is convenient to operate, so as to improve the potato production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Please refer to Figures 1 to 4, An improved structure of a greenhouse sprinkler for potato bottle seedling planting. The greenhouse sprinkler includes a main pipe 1 vertically arranged and connected to a water source, a horizontal conveying pipe 2 vertically connected to the main pipe 1 for conveying water, a plurality of hoses 3 arranged at equal intervals along the length direction of the horizontal conveying pipe 2 for diverting water, and a nozzle 4 provided at the end of the hose 3 for spraying water. The improvement lies in that a variable distance mechanism 5 for adjusting the distance between a plurality of nozzles 4 is provided on the horizontal conveying pipe 2. The above variable distance mechanism 5 is composed of a frame 6 connected to both ends of the horizontal conveying pipe 2, a driving component 7 provided on the frame 6, and a plurality of moving rods 8 connected to the driving component 7. The driving component 7 can drive the plurality of moving rods 8 to approach or move away synchronously, and the plurality of nozzles 4 are arranged in one-to-one correspondence with the plurality of moving rods 8, and the nozzle 4 is correspondingly connected to the moving rod 8. The driving component 7 for driving the plurality of moving rods 8 to approach or move away synchronously is composed of an electric push rod 9 vertically provided on the frame 6, a variable distance adjusting plate 10 connected to the output shaft of the electric push rod 9, and two guide rods 11 horizontally provided on the frame 6. The variable distance adjusting plate 10 is vertically slidably matched with the frame 6, and a plurality of sliding grooves 12 are provided on the variable distance adjusting plate 10, and the plurality of sliding grooves 12 are fan-shaped. Then, a slider 13 adapted to the sliding groove 12 and slidably matched with the sliding groove 12 is provided on the moving rod 8. The plurality of moving rods 8 are all horizontally slidably matched with the two guide rods 11. By starting the electric push rod 9 to drive the variable distance adjusting plate 10 to move up and down, when the variable distance adjusting plate 10 moves, the plurality of sliding grooves 12 provided thereon will move together, thereby driving the plurality of sliders 13 to move along the positions of the corresponding sliding grooves 12. Since the plurality of sliding grooves 12 are fan-shaped, the plurality of moving rods 8 are driven to approach or move away synchronously, thereby driving the plurality of nozzles 4 to approach or move away synchronously, realizing the adjustment of the distance between the plurality of nozzles 4.

[0018] The above two guide rods 11 are used to fix the positions of the plurality of moving rods 8 when they move horizontally.
