[0016] In summary, the present invention includes the following beneficial technical effects: The present invention provides a bifurcated horizontal water pipe, a bifurcated horizontal fertilizer pipe, a bifurcated vertical water pipe, a bifurcated vertical fertilizer pipe, a material transfer hole and a liquid spraying ring. During transportation, fertilizer is added into the material transfer hole below through the main fertilizer pipe, the bifurcated horizontal fertilizer pipe and the bifurcated vertical fertilizer pipe. Liquid fills water into the material transfer hole below through the main water pipe, the bifurcated horizontal water pipe and the bifurcated vertical water pipe. Then, when the material transfer ring drives the material transfer hole storing fertilizer to rotate to the bottom of the bottom cavity arc plate, water flows into the material transfer hole containing fertilizer. The water flows drive the fertilizer to enter the inner cavity ring and the liquid spraying ring through the through groove, so that the fertilizer and the liquid are mixed before spraying, which effectively prevents the fertilizer from settling and clogging during transportation. The fertilizer located in the inner cavity ring and the liquid spraying ring can be impacted by the water flow all the time, so as to ensure that the fertilizer can be fully mixed in the liquid.

[0017] The present invention arranges a spacer ring, a hollow rod and a liquid-permeable groove. When the amount of liquid filled into the inner cavity ring is small or there is no liquid inside, the spacer ring is elastically connected to the inner cavity ring and is located above the liquid-permeable groove, so that the liquid that initially enters the inner cavity ring will not directly enter the liquid spraying ring. Only when the liquid in the inner cavity ring reaches a sufficient pressure, the mixed liquid in the inner cavity ring can enter the hollow rod through the liquid-permeable groove above the hollow rod, and then enter the liquid spraying ring through the liquid-permeable groove on the lower side of the hollow rod, so that the interior of the liquid spraying ring can be evenly filled with liquid and then evenly sprayed from below.

[0018] The present invention provides a feeding rod. When the feeding ring rotates, the upper end of the feeding hole is driven to contact the conical surface of the lower end of the feeding rod. The feeding hole is subjected to force through the conical surface of the feeding rod, thereby pushing the feeding rod to move upward. When the feeding rod coincides with the feeding hole again, the feeding rod is reinserted into the feeding hole under the action of elasticity. When the feeding ring continues to rotate, the feeding rod can be driven to move back and forth up and down, continuously pushing the fertilizer in the forked vertical fertilizer pipe up and down. The annular concave structure on the surface of the feeding rod can assist in driving the fertilizer to move up and down, thereby effectively preventing the fertilizer from being blocked in the forked vertical fertilizer pipe.

[0019] The present invention provides a reflux pipe. When the fertilizer entering the bifurcated horizontal fertilizer pipe does not completely enter the bifurcated vertical fertilizer pipe, the fertilizer in the bifurcated horizontal fertilizer pipe moves to one end away from the main fertilizer pipe and enters the reflux pipe. Then the fertilizer flows back into the discharge barrel through the reflux pipe and can be transported again when the soft spiral feeding plate rotates. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A plurality of fertilizer liquid outlet structures 5 are installed on the bottom surface of the bifurcated horizontal fertilizer pipe 8 .

[0028] The fertilizer liquid outlet structure 5 includes a bifurcated vertical fertilizer pipe 51, the upper end of which is connected to the bottom surface of the adjacent bifurcated horizontal fertilizer pipe 8, and the lower end of the bifurcated vertical fertilizer pipe 51 is fixedly sleeved with a fixed top ring 52, and the outer surface of the fixed top ring 52 is concentrically sleeved with an inner cavity ring 53, and the lower part of the fixed top ring 52 is rotatably contacted with a transfer ring 55, and the upper surface of the transfer ring 55 is provided with a plurality of transfer holes 54, and a feeding rod 514 is provided at the inner axis of the bifurcated vertical fertilizer pipe 51, and the maximum outer diameter of the feeding rod 514 is smaller than the inner diameter of the bifurcated vertical fertilizer pipe 51, and the lower end of the feeding rod 514 is conical, and the conical part of the lower end of the feeding rod 514 is located inside the adjacent lower transfer hole 54, and the feeding rod 51 4 is provided with a plurality of annular recessed structures on the outer circumferential side surface, and the upper end of the feeding rod 514 is elastically connected to the inner wall of the bifurcated vertical fertilizer pipe 51.

A torque motor 57 is fixedly installed on the inner wall of the upper end of the inner cavity ring 53, and the driving gear 56 is fixedly sleeved on the output end of the torque motor 57. The torque motor 57 can drive the material transfer ring 55 to rotate through the meshing of the driving gear 56 and the tooth ring groove 58.

[0030] The bottom surface of the inner cavity ring 53 is concentrically connected with a liquid spraying ring 59, and the bottom surface of the liquid spraying ring 59 is perforated. When the inside of the liquid spraying ring 59 is filled with a fertilizer mixture, the fertilizer liquid can be sprayed. The inner cavity ring 53 is slidably inserted with a spacer ring 531, and the spacer ring 531 is elastically connected to the inner cavity ring 53.

After the liquid enters the inner cavity ring 53, the spacer ring 531 is pushed downward. When the liquid permeable groove 533 on the upper side leaks out from above the spacer ring 531, the mixed liquid in the inner cavity ring 53 can enter the hollow rod 532 through the liquid permeable groove 533 above the hollow rod 532, and then enter the liquid spraying ring 59 through the liquid permeable groove 533 on the lower side of the hollow rod 532, so that the interior of the liquid spraying ring 59 can be evenly filled with liquid and then evenly sprayed from below.

[0031] The upper surface of the fixed top ring 52 is concentrically fixedly plugged with a bottom cavity arc plate 510, and the upper surface of the bottom cavity arc plate 510 is connected and installed with a bifurcated vertical water pipe 511, and the upper end of the bifurcated vertical water pipe 511 is connected and installed with the adjacent bifurcated horizontal water pipe 10, and a through groove 512 is opened on the upper surface of the inner cavity ring 53 and located directly below the bottom cavity arc plate 510, and a filter arc plate 513 is concentrically arranged below the bottom cavity arc plate 510, and the filter arc plate 513 is fixedly plugged inside the through groove 512, and the lower end of the filter arc plate 513 is connected with the inside of the inner cavity ring 53, and the filter arc plate 513 effectively prevents excessive undissolved fertilizer from entering the inner cavity ring 53 and the spray ring 59, and the arc angle range of the filter arc plate 513 is The arc angle of the filter arc plate 513 is equal to the arc angle of the bottom cavity arc plate 510, and the arc angle of the filter arc plate 513 is greater than the distance between two adjacent transfer holes 54, so that the liquid can melt the fertilizer in at least two transfer holes 54.

The distance between the transfer hole 54 on the surface of the same transfer ring 55 and the axis of the transfer ring 55 is equal to the distance between the filter arc plate 513 and the corresponding axis of the transfer ring 55, so that the transfer hole 54 can be connected with the bottom cavity arc plate 510 during the rotation of the transfer ring 55.

[0032] The working principle is as follows: put the fertilizer into the discharge barrel 3, and when the soft spiral feeding plate 43 rotates, the fertilizer is fed into the main fertilizer pipe 2 through the feeding pipe 41, and then when the main feeding spiral plate 6 rotates, the fertilizer falls into the forked horizontal fertilizer pipe 8 through the double-hole tube 7, and then enters the connected forked horizontal fertilizer pipe 8, and then the fertilizer is transmitted when the auxiliary feeding spiral plate 9 rotates, and the fertilizer falls into the forked vertical fertilizer pipe 51 when passing through the forked vertical fertilizer pipe 51, and the fertilizer in the forked vertical fertilizer pipe 51 falls into the feeding hole 54 connected below, and the torque motor 57 drives the feeding ring 55 to rotate through the driving gear 56 and the tooth ring groove 58, and the liquid passes through the main water pipe 1, the forked horizontal water pipe 10 and the forked vertical water pipe 5 11 Fill water into the transfer hole 54 below. When the transfer ring 55 drives the transfer hole 54 storing fertilizer to rotate to the bottom of the bottom cavity arc plate 510, water flows into the transfer hole 54 containing fertilizer, and the water flows drive the fertilizer to pass through the through groove 512 into the inner cavity ring 53 and the spray ring 59 for mixing. The mixed liquid gradually pushes the partition ring 531 to move downward. When the upper liquid permeable groove 533 leaks out from above the partition ring 531, the mixed liquid in the inner cavity ring 53 can enter the hollow rod 532 through the liquid permeable groove 533 above the hollow rod 532, and then enter the spray ring 59 through the liquid permeable groove 533 on the lower side of the hollow rod 532, so that the interior of the spray ring 59 can be evenly filled with liquid and then evenly sprayed from below.

[0033] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
