Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to an integrated water and fertilizer sprinkler irrigation machine. Background Technology

[0002] In modern agricultural production, to improve the efficiency of water and fertilizer utilization, reduce labor costs, and achieve precision irrigation and fertilization, integrated water and fertilizer sprinkler irrigation machines have emerged. An integrated water and fertilizer sprinkler irrigation machine is an intelligent agricultural machinery device that integrates irrigation and fertilization.

[0003] In existing integrated water and fertilizer sprinkler irrigation technology, the typical process is as follows: fertilizer and water are added to the storage tank of the sprinkler irrigation machine in proportion, and the mixture is stirred by the stirring device to make the fertilizer and water initially evenly mixed; then the sprinkler irrigation machine is started, and the mixture flows into the nozzle through the delivery pipe, and is sprayed onto the farmland through the nozzle nozzle to complete the irrigation operation; after the operation is completed, the sprinkler irrigation machine is turned off and the equipment is simply cleaned and stored.

[0004] In existing technologies, undissolved particles may remain during fertilizer dissolution, or impurities may be introduced into the mixture. Over long-term sprinkler irrigation, these impurities easily accumulate at the nozzles. Once the nozzles are clogged, uneven spraying occurs, resulting in insufficient irrigation in some areas and negatively impacting crop growth. In severe cases, the nozzles may become completely blocked, interrupting irrigation and requiring frequent manual disassembly and cleaning. This not only increases labor intensity but also reduces irrigation efficiency, making it difficult to guarantee the continuity and uniformity of sprinkler irrigation. Therefore, a water and fertilizer integrated sprinkler irrigation machine is proposed to address these problems. Summary of the Invention

The stirring blade 18 is fixedly connected to the bottom end of the stirring rod 17, stirring the water-fertilizer mixture to make it fully and evenly mixed. The top end of the stirring rod 17 is fixedly connected to a bevel gear B9, which meshes with the bevel gear A8, receiving and transmitting power. The surface of the bevel gear A8 meshes with the top of the bevel gear B9 to realize the reversal of power transmission, driving the stirring rod 17 to rotate.

[0030] Working principle: The motor 6 drives the rotating rod A7 to rotate through the output shaft. The bevel gear A8 on the surface of the rotating rod A7 meshes with the bevel gear B9 at the top of the stirring rod 17, so that the stirring blade 18 at the bottom of the stirring rod 17 stirs the water-fertilizer mixture in the tank 4. The mixture flows into the nozzle 13 through the discharge pipe 5 and is evenly sprayed through the nozzle 24 on the front of the nozzle 13.

[0031] Through the transmission of rotating rod A7 and rotating rod B20, rotating rod A7 drives rotating rod B20 to rotate in the same direction, causing rotating rod B20 to drive elliptical cam 15 to rotate, pushing extension plate 21 and moving plate 14, causing push rod 16 to reciprocate within nozzle 24 to clear blockages;

[0032] Rotate knob 11 to drive threaded rod 19, so that slider 12 drives nozzle 13 to slide in sliding hole A to achieve storage or expansion. Add fertilizer and water to tank 4 in proportion, start motor 6, and the stirring component works to make the mixture uniform.

[0033] Push the handle 10 and move the sprinkler to the work area via the caster wheels 3; rotate the knob 11 to adjust the position of the nozzle 13 as needed; the mixed liquid enters the nozzle 13 through the feed pipe 5 and is sprayed; during operation, the unclogging component automatically cleans the nozzle 24; after use, turn off the motor 6, rotate the knob 11 to store the nozzle 13, and install the dustproof plate 2 with bolts to prevent dust.
