[0023] The present invention will be further described below with reference to the drawings and embodiments.
[0024] Such as image 3 The shown method of split application of seed fertilizer includes the following steps:
[0025] (1) Use a furrow opener to make a planting ditch on the farmland, the depth of the planting ditch is 5cm;
[0026] (2) Use a seed and fertilizer applicator to alternately place seeds and fertilizers in the planting ditch, with a certain distance between the seeds and the fertilizer.
[0027] The distance between the seed and the fertilizer is 10cm-20cm. Specifically, the distance between seeds and fertilizer is determined according to actual conditions. The distance between seeds and fertilizer can be controlled by the horizontal movement speed of the seed fertilizer applicator and the seed fertilizer conveying wheel. For example, when using corn seeds, the distance between corn seeds and fertilizer is 15mm. That is, 15 cm is preferred in this embodiment.
[0028] The fertilizer application amount between the adjacent seeds is 10g. When planting precision corn, the amount of fertilizer applied between adjacent seeds is 10g.
[0029] Such as Figure 4 As shown, the alternate seed fertilizer applicator includes a fertilizer chamber cover 1, a seed chamber cover 2, a fertilizer extractor 3, a seed fertilizer conveying wheel 4, a seed extractor 5, a housing 6 and a rotating shaft. The fertilizer chamber cover 1 and The seed chamber cover 2 is installed on both sides of the seed fertilizer conveying wheel 4. The fertilizer chamber cover 1, the housing 6 and the seed fertilizer conveying wheel 4 form a fertilizer chamber. The seed chamber cover 2, the housing 6 and the seed fertilizer conveying The wheel 4 forms a seed chamber, and the lower end of the shell 6 is provided with a discharge port 61 communicating with both the fertilizer chamber and the seed chamber;
[0030] The fertilizer extractor 3 and the seed extractor 5 are respectively installed in the fertilizer room and the seed room. Both the fertilizer extractor 3 and the seed extractor 5 are connected to the seed fertilizer conveying wheel 4 through a rotating shaft; There is a fertilizer tank 41 on the periphery of one side, and a seed tank 42 on the periphery of the other side. The fertilizer tank 41 and the seed tank 42 are alternately arranged, and the fertilizer tank 41 and the seed tank 42 communicate with the fertilizer chamber and the seed chamber respectively. . The outer edges of the left and right sides of the seed fertilizer conveying wheel 4 are provided with alternately dividing fertilizer tanks 41 and seed tanks 42. The fertilizer tank 41 corresponds to the fertilizer finger 32 of the fertilizer extractor 3, and the seed tank 42 corresponds to the fertilizer finger 52 of the seed extractor 5, so as to ensure that the fertilizer extractor 3 can send the fertilizer from the fertilizer chamber to the fertilizer tank 41. It is ensured that the seed extractor 5 can send the seeds from the seed chamber to the seed tank 42.
[0031] The fertilizer extractor 3 includes a fertilizer wheel body 31 and a plurality of fertilizer fingers 32. One end of the fertilizer finger 32 is fixed to the outer edge of the fertilizer wheel body 31 and is different from the outer edge of the fertilizer wheel body 31. There is a first included angle between them, and the size of the first included angle is 60°; the fertilizer finger 32 is provided with a fertilizer extraction groove, and the fertilizer extraction groove faces the seed fertilizer conveying wheel. Specifically, the fertilizing finger 32 and the fertilizing wheel 31 have an included angle, which is more conducive to the fertilizing finger 32 sending fertilizer from the fertilizer chamber to the fertilizer tank 41, thereby improving reliability. In order to further improve the reliability, the fertilizer extraction finger 32 is provided with a fertilizer extraction groove. When the fertilizer extractor 3 rotates with the rotating shaft, the fertilizer finger 32 can obtain fertilizer more easily, and the fertilizer is stored in the fertilizer tank, and the fertilizer enters the fertilizer tank from the fertilizer tank to complete the fertilizer extraction effect.
[0032] The seed picker 5 includes a seed picking wheel 51 and a plurality of seed picking fingers 52. One end of the seed picking finger 52 is fixed to the outer edge of the seed picking wheel 52 and is different from the outer edge of the seed picking wheel 51. There is a second included angle between them, and the size of the second included angle is 60°; the seed taking finger 52 is provided with a seed taking groove, and the seed taking groove faces the seed fertilizer conveying wheel 4. The structure of the seed extractor 5 is the same as that of the fertilizer extractor 3, and the working principle is the same, except that the seed extractor 5 obtains seeds instead of fertilizer.
[0033] The fertilizer tank 41 has a groove width of 2 cm and a radial depth of 2 cm; the seed groove 42 has a groove width of 1 cm and a radial depth of 2 cm.
[0034] A fertilizer separator 7 is provided between the fertilizer extractor 3 and the seed fertilizer conveying wheel 4. The outer edge of the fertilizer separator 7 is provided with a first notch 71, and the first notch 71 is located on the fertilizer separator The upper end of 7; the seed separator 8 is provided between the seed extractor 5 and the seed fertilizer conveying wheel 4, the outer edge of the seed separator 8 is provided with a second gap 81, and the second gap 81 is located Kind of the upper end of the partition 8. The fertilizer separator 7 is fixedly connected to the housing 6, and its outer edge is provided with a first notch 71. The first notch 71 is located at the upper end of the fertilizer separator 7. When the fertilizer extractor 3 rotates, the fertilizer extractor 3 The fertilizer is sent from the first gap 71 to the fertilizer tank 41, so as to ensure the delivery of the fertilizer; in the same way, the seed-taken partition 8 is fixedly connected to the housing 6, and the outer edge is provided with a second gap 81. The notch 81 is located at the upper end of the seed-taken partition 8, and when the seed-taker 5 rotates, the seed-taker 5 will send the seeds from the second notch 81 to the seed tank 42, so as to ensure the transportation of the seeds.
[0035] The outer side of the fertilizer chamber cover 1 is provided with a fertilizer inlet 11 communicating with the fertilizer chamber, and the outer side of the seed chamber cover 2 is provided with a seed inlet 21 communicating with the seed chamber. The fertilizer inlet 11 has a tubular profile, and the fertilizer inlet 11 faces upwards. To prevent the fertilizer from being thrown out of the fertilizer chamber, the opening of the fertilizer inlet 11 is located at the highest point of the fertilizer chamber cover 1. Similarly, the seed inlet 21 has the same structure as the fertilizer inlet 11, and the opening of the seed inlet 21 is located at the highest point of the seed chamber cover 2.
[0036] The above-mentioned specific implementations are preferred embodiments of the present invention and do not limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solutions of the present invention are included in the protection scope of the present invention. within.
