Abstract

The invention discloses a sprinkler for achieving a high atomization effect under a low pressure condition, which belongs to a modern agricultural micro-irrigation apparatus, and comprises a low-pressure fine atomizing nozzle, a small motor fan, a storage battery pack, slotted brackets, a screw rod and adjustable screw nuts, the components of the sprinkler are connected with each other via threads and bolts, and the slotted bracket has a U-shaped slot. The low-pressure atomizing sprinkler can realize height adjustment of the sprinkler through threaded connection of the threaded connecting pipe according to the height of the plant to be sprinkled, and the operation is simple. Effective atomization can be achieved under a low pressure condition and atomization uniformity can be improved by the action of the small motor fan. The sprinkler for achieving a high atomization effect under a low pressure condition is convenient to assemble, the user can quickly install the sprinkler and achieve different atomization effects according to the requirement, so that a single apparatus has multiple functions and effectively overcome drawbacks of the mechanical operation and only functioning in pressure adjustment of the agricultural atomizing sprinklers in the prior art.

First claim

We claim:

1. A sprinkler for achieving a high atomization effect under a low pressure condition, comprising a threaded connecting pipe, a low-pressure fine atomizing nozzle, a small motor fan, a storage battery pack, a top slotted bracket, a bottom slotted bracket, a screw rod, and adjustable screw nuts, wherein, the low-pressure fine atomizing nozzle is connected to the threaded connecting pipe, and atomization pressure is adjusted via a valve;
the screw rod is disposed in parallel on one side of the threaded connecting pipe, a top end of the screw rod is connected to the threaded connecting pipe via the top slotted bracket, the bottom slotted bracket is disposed at a bottom end of the screw rod, the small motor fan is disposed on the bottom slotted bracket and comprises a small motor and a m-blade propeller fan, the small motor fan can move left and right in a U-shaped slot of the bottom slotted bracket to adjust an axial distance from the low-pressure fine atomizing nozzle, the adjustable screw nut can be screwed up and down on the screw rod to adjust a lateral distance between the small motor fan and the low-pressure fine atomizing nozzle, and the storage battery pack supplies power to the small motor fan.

2. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 comprising the top slotted bracket comprises a pipe fitting hole and a support plate, and the diameter of the pipe fitting hole is greater than the diameter of the threaded connecting pipe, so that the top slotted bracket can move up and down on the threaded connecting pipe; the pipe fitting hole has a threaded hole in its wall surface, and the top slotted bracket can be fixed by screwing in and out of a bolt with appropriate size in the threaded hole the support plate is disposed at the other end of the top slotted bracket and has a U-shaped slot, so that the screw rod can move left and right in the top slotted bracket.

3. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 the U-shaped slot is provided at one end of the bottom slotted bracket, to realize left and right movement and fixing of the small motor fan; an open hole is provided at the other end of the bottom slotted bracket, via which the screw rod is connected between the top slotted bracket and the bottom slotted bracket; the storage battery pack is fixed on one end of the bottom slotted bracket near the open hole, and comprises a battery case that contains n dry battery cells and is disposed at the lower end of the bottom slotted bracket via waterproof wires.

4. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 comprising the threaded connecting pipe is connected with the low-pressure fine atomizing nozzle via threads.

5. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 comprising the top slotted bracket is connected with the bottom slotted bracket via the screw rod.

6. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 comprising the storage battery is connected to the bottom slotted bracket by adhesive bonding.

7. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 1 comprising the m-blade propeller is a propeller with one or more blades.

8. The sprinkler for achieving a high atomization effect under a low pressure condition according to claim 3 comprising the n dry battery cells contain one or more dry battery cells.
