[0016] A dual-chamber stratified fertilizer seeder, such as Figure 1 As shown, it includes: The vehicle body 10 has a seed box 11 fixedly installed on its top and a seed discharge pipe 12 fixedly installed on its bottom. The vehicle body 10 also has a fertilizer box 13 fixedly installed on its top. The fertilizer box 13 has two independent chambers and fertilizer pipes 14 extending into the two chambers are fixedly installed on its bottom. The fertilizer bin 13 has an internal partition, forming two independent chambers. One chamber is used to hold potassium fertilizer, and the other is used to hold calcium fertilizer. Potassium fertilizer needs to be applied deeply, while calcium fertilizer needs to be applied shallowly. The left side of the vehicle body 10 is connected to the direction of travel, so the vehicle body 10 travels to the left. The left-side chamber is used to hold potassium fertilizer. A trencher is also fixedly installed at the bottom of the vehicle body 10. The following are fixedly installed at the bottom of the vehicle body 10 along the direction of travel: Main furrow opener: Located at the front, used to open the initial seed and fertilizer furrow, depth H1 (adjustable, for example, 150-200mm for deep application of potassium fertilizer).

[0017] Fertilizer pipe 14a: located immediately behind the main furrower, connected with the left chamber (potassium fertilizer chamber) of the fertilizer box 13, and potassium fertilizer is applied to the bottom of the furrow opened by the main furrower.

[0018] Covering wheel 22a: located behind the deep fertilizer pipe 14a, used to backfill and cover the deep-applied potassium fertilizer with part of the soil, forming a cover layer with a thickness T1 (e.g. 50-70 mm).

[0019] Fertilizer pipe 14b: located behind the covering wheel 22a, connected with the right chamber (calcium fertilizer chamber) of the fertilizer box 13, and calcium fertilizer is applied to the surface of the soil backfilled by the covering wheel 22a.

[0020] Covering wheel 22b: located behind the fertilizer pipe 14b, used to backfill and cover the shallow-applied calcium fertilizer with a small amount of soil, forming a cover layer with a thickness T2 (e.g. 20-30 mm).

[0021] Seed discharge pipe 12: located behind the covering wheel 22b, used to discharge seeds onto the calcium fertilizer cover layer.

[0022] Covering wheel 22c: located at the back, used to completely backfill and cover the seeds with soil, forming the final ground surface. The letters a, b and c in the above text are only used to distinguish the arrangement order, and the structures are the same. For example, the fertilizer pipe a and the fertilizer pipe b are the same, only the positions are different. The letters a and b are used to distinguish them for convenience of description.

[0023] Through the above layout, the layered fertilization and seeding operation process of deep potassium fertilization, covering, shallow calcium fertilization, covering, seeding, and covering is realized. The heights of the covering wheels 22a, 22b, and 22c can be independently adjusted through their respective adjusting structures to control the covering thickness T1, T2, and the final covering depth. The potassium fertilizer is discharged into the trench through the left fertilizer pipe 14, and after covering, the calcium fertilizer is applied again, and the soil is covered again. Then the seeds are sown through the seed discharge pipe 12, and finally the trench is backfilled to realize seeding. After the seeds germinate and root, the calcium fertilizer can be absorbed first, and during the fruiting period, the roots can sink to absorb the potassium fertilizer. Taking peanuts as an example, two fertilizations can be realized during the cultivation process, and the depth of fertilization is adjusted according to the fertilizer required by the growth stage of peanuts, which improves the yield of peanuts and reduces the workload of supplementary fertilization.

[0024] As shown in Figure 2 and Figure 3 , the covering structure is alternately arranged between the seed discharge pipe 12 and the fertilizer pipe 14 for backfilling soil, and the covering structure includes a mounting plate 20, a connecting shaft 21, and a covering wheel 22. The mounting plate 20 is fixedly installed with the vehicle body 10, the connecting shaft 21 is rotationally connected with the covering wheel 22, and a first gasket 23 is arranged on one side of the mounting plate 20 and rotationally connected with the connecting shaft 21.

The mounting plate 20 is a rectangular plate, and an adjustment channel 24 for sliding of the connecting shaft 21 is formed through the mounting plate 20. The adjustment channel 24 is clearance-fitted with the connecting shaft 21. The thrust groove 30 is a central hole, and the thrust groove 30 and the adjustment channel 24 have overlapping portions. The diameter of the thrust groove 30 is larger than the width of the adjustment channel 24. The thrust groove 30 is less than the depth of the adjustment channel 24. The part of the thrust groove 30 that protrudes from the adjustment channel 24 forms a crescent-shaped groove. The thrust ring 31 is a circular ring. The inner diameter of the thrust ring 31 is equal to the diameter of the connecting shaft 21. The outer diameter of the thrust ring 31 is equal to the diameter of the thrust groove 30. The adjustment structure also includes a second washer 32 and a retaining spring 33. The second washer 32 is located on one side of the thrust ring 31. The retaining spring 33 engages with the connecting shaft 21 and limits the second washer 32. A disc spring washer is provided between the retaining spring 33 and the second washer 32. The connecting shaft 21 has an annular groove adapted to the retaining spring 33. The retaining spring 33 is engaged in the annular groove. To achieve individual adjustment of the soil covering depth of the three sets of soil covering structures, the isolation cover on one side of the mounting plate 20 is removed. The isolation cover is locked to the mounting plate 20 with screws. Then, the retaining spring 33 and the second washer 32 are removed, and the thrust ring 31 is pulled out. The thrust ring 31 exits from the thrust groove 30. The connecting shaft 21 is pushed up or down, and the connecting shaft 21 slides in the adjustment channel 24. When the connecting shaft 21 reaches the required height, the thrust ring 31 is put on the connecting shaft 21 and snaps into the corresponding thrust groove 30. The second washer 32 is then placed in, and the retaining spring 33 is snapped into the annular groove to position the connecting shaft 21. The second washer 32, together with the first washer 23, clamps the mounting plate 20 to prevent the connecting shaft 21 from detaching from the mounting plate 20. Then, the isolation cover is put back on. This method allows for precise adjustment of the soil covering wheel 22's ground clearance. The adjustment method is simple and quick, and the position of the connecting shaft 21 is well fixed, making it less prone to loosening or falling off.

[0025] The working principle of this utility model is as follows: Remove the isolation cover on one side of the mounting plate 20. The isolation cover is locked to the mounting plate 20 by screws. Then remove the retaining spring 33 and the second washer 32. Pull out the thrust ring 31. The thrust ring 31 exits from the thrust groove 30. Push the connecting shaft 21 up or down. The connecting shaft 21 slides in the adjustment channel 24. When the connecting shaft 21 reaches the required height, put the thrust ring 31 on the connecting shaft 21. The thrust ring 31 is inserted into the corresponding position of the thrust groove 30. Put in the second washer 32, and then put the retaining spring 33 in. The connecting shaft 21 is positioned by inserting it into the annular groove. The second washer 32, together with the first washer 23, clamps the mounting plate 20 to prevent the connecting shaft 21 from detaching from the mounting plate 20. Then, the isolation cover is placed on top. The fertilizer pipe 14 on the left side sprinkles potassium fertilizer into the ditch. After covering with soil, calcium fertilizer is applied and covered with soil again. Then, the seeds are sown through the seed pipe 12. Finally, the ditch is backfilled with soil to achieve sowing. After the seeds germinate and take root, they can first absorb calcium fertilizer. During the fruiting period, the roots can absorb potassium fertilizer by descending. This achieves two fertilizations during the sowing process. The seed box 11 is equipped with an external grooved wheel seed metering device at its bottom, and each chamber of the fertilizer box 13 is equipped with a star wheel fertilizer metering device at its bottom. The rotating shafts of the seed metering device and the fertilizer metering device are connected to the ground wheels of the seeder (or an independently driven hydraulic motor / electric motor) via chain drive or universal joint drive shaft. By changing different sizes of grooved wheels or star wheels, and adjusting the transmission ratio, the seed dispensing rate and fertilizer dispensing rate can be changed to match the needs of different crops and the travel speed. The furrow opener is raised and lowered by a hydraulic cylinder.
