Improved swing water sprinkler adjustable in sprinkling angle

Abstract

The improved swing sprinkler with adjustable spraying angle is a dry commutator without water, the gear set is dry and the gears of the gear set are Austrian, so it is durable; the adjustable spraying angle swing sprinkler On the outside of each shaker nozzle (59) of the device, the right dial groove and the left dial groove with progressively increasing inclination angles of the dial (598) are respectively set in turn, and four dials (598t) are used, and every two dials Shared dialing gear with handle, the four dials (598t) are successively provided with right and left shifting grooves with increasing inclination angles, forming a high-precision, high-angle and accurate spraying angle adjustable swing sprinkler. Perfect, it solves the persistent problems of difficult reversing, unreliable and inaccurate spraying angle.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is a high-performance anti-fouling swing sprinkler and a water-saving method, and an electromagnetic flowmeter including a new type of energy-saving impeller suspension shaftless support for energy-saving agriculture and forestry irrigation And circuit and water-saving method, including flow adjustable dripper, 360-degree nozzle, connector with fine-tuning thread ring size and pitch, and energy-saving sprinkler timer and water distributor with multi-purpose interface, and improved Spray angle adjustable swing sprinkler. Background technique [0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of watering water flow, and the timing switch of garden sprinklers controlled by both sides of the long axis, such as patent US7252113B2, and Patent ZL200820120164.8 all adopts ...

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The existing electromagnetic flowmeter is made based on Faraday's principle of electromagnetic induction. When the conductor cuts the magnetic force line in the magnetic field, an induced potential proportional to the liquid flow rate is generated, and is detected by the electrode in contact with the liquid, so that it is converted by the cable. After intelligent processing, the communication and control between the flow data and the computer are realized. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, electrodes, an excitation wire, a measuring tube housing, a circuit board and The display device, in which the measuring tube, the inlet flange, the outlet flange and the measuring tube housing are all made of metal materials, the disadvantages of using metal materials are: the weight of the entire flowmeter is relatively large, and it is inconvenient to install and maintain. The work is completed with the cooperation of people, which affects work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive
