[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-6 A contour-following foldable multi-strip tiller includes a foldable main frame 1. A lower suspension frame 5 and an upper suspension frame 6 are installed on the main beam I4 in the middle of the foldable main frame 1, forming the machine's suspension system. Main beams II8 are respectively installed on the left and right sides of the main beam I4 in the middle of the foldable main frame 1. Hydraulic cylinder seats 7 are installed between the main beams I4 and II8, and between the main beams I4. The row spacing adjustment hydraulic cylinder 10 is installed on the hydraulic cylinder seat 7. A folding shaft 9 is installed at one end of the main beam II8. A four-bar contour-following mechanism 11 is installed on the inner side of each main beam I4 and main beam II8. A folding hydraulic cylinder support plate 13 is installed on the main beam I4 in the middle of the foldable main frame 1. A hydraulic cylinder seat 7 is installed on the folding hydraulic cylinder support plate 13. A folding hydraulic cylinder 12 is installed on the hydraulic cylinder seat 7. When the folding hydraulic cylinder 12 retracts, the foldable main frame 1 folds 90 degrees with the folding shaft 9 as the fulcrum.

[0019] The strip tiller unit 2 consists of a strip tiller unit frame 14, adjustable depth limiting wheels 15, a deep tillage shovel and fertilizer application tube 16, a deep tillage shovel 17, a disc harrow 18, a four-bar linkage connecting seat 19, a deep tillage shovel seat 20, a disc harrow seat 21, a U-shaped clamp 22, a press roller bracket 23, a press roller drive hydraulic motor 24, a press roller 25, a strip tillage cutter roller drive hydraulic motor 26, a strip tillage cutter roller 27, and a disc harrow and fertilizer application tube 28. A subsoil shovel seat 20 is installed at the front of the strip tiller unit frame 14, and the subsoil shovel 17 is installed on the subsoil shovel seat 20. The implement first completes the subsoil operation. A four-bar linkage guide mechanism link seat 19 is also set at the front of the strip tiller unit frame 14. The four-bar linkage guide mechanism link seat 19 is connected to the four-bar linkage guide mechanism 11 on the foldable main frame 1 to form the four-bar linkage guide mechanism of the implement. Adjustable depth limiting wheels 15 are set at both ends of the front of the strip tiller unit frame 14. By adjusting the adjustable depth limit... The height of the deep-ground wheel 15 determines the working depth of the strip tiller unit 2. Disc harrow seats 21 are fixed on the second and third beams of the strip tiller unit frame 14, and disc harrows 18 are mounted on these seats. Two disc harrows 18 are installed on each beam. The two disc harrows 18 on the second beam are spaced 800 mm apart, and the two disc harrows 18 on the third beam are spaced 300 mm apart. This staggered distribution of the disc harrows 18 on the second and third beams avoids congestion. The soil is fertilized by a deep tillage shovel 16 located behind the deep tillage shovel 17. After deep tillage, base fertilizer is applied via the deep tillage shovel fertilization pipe 16. A disc harrow fertilization pipe 28 is located behind the disc harrow 18. After the disc harrow 18 finishes harrowing, the disc harrow fertilization pipe 28 applies nutrient fertilizer. Since the fertilizer applied by the disc harrow fertilization pipe 28 is applied to the topsoil, it is mixed with the soil by the subsequent strip tillage rollers 27, forming a full-layer mixed fertilizer in the strip tillage layer, which can provide nutrients to seedlings throughout their growth period. A fertilization pipe 16 is located at the rear of the strip tiller unit frame 14. The strip tillage roller 27 is driven by the strip tillage roller drive hydraulic motor 26, which reduces the failure rate of mechanical transmission. The press roller bracket 23 is fixed on the rear beam of the strip tiller unit frame 14 by U-shaped clips 22. The press roller 25 is installed on the press roller bracket 23 and is driven by the press roller drive hydraulic motor 24. The press roller 25 compacts the soil after the strip tillage roller 27 has worked, forming a flat strip tillage operation zone with a certain degree of compaction.

[0020] Multiple strip tiller units 2 are connected to the four-bar linkage 11 of the foldable main frame 1 via a four-bar linkage connecting seat 19 to form a contoured foldable multi-strip strip tiller. When the ridge spacing adjustment hydraulic cylinder 10 on the foldable main frame 1 extends or retracts, the spacing between adjacent strip tiller units 2 also changes to adapt to the requirements of different ridge spacing operations, thus achieving the purpose of adjusting the ridge spacing. When the folding hydraulic cylinder 12 on the foldable main frame 1 retracts, the foldable main frame 1 folds 90 degrees with the folding shaft 9 as the fulcrum, causing the strip tiller units 2 on both sides of the foldable main frame 1 to also be in a folded state. This is the non-operational transport state.

[0021] The fertilizer box 3 is fixed on the strip tiller unit 2 located in the middle position, and fertilizer is supplied to the deep tillage shovel fertilizer pipe 16 and the disc harrow fertilizer pipe 28, forming the fertilization system of the machine.
