The mounting base 1 serves as the load-bearing foundation for the entire tilling device, and is integrally welded from Q235 low carbon steel plate with a plate thickness of 8mm-10mm. This ensures structural strength to withstand the weight of subsequent components and operational impacts while controlling the overall weight for easy traction and movement. The main body of the fertilizer box 2 is made of food-grade polyethylene. Injection molding. This material has good corrosion resistance and can effectively resist the chemical erosion of fertilizers such as urea and compound fertilizers. It is also lightweight, which can reduce the load on the entire device. The wall thickness is set at 5mm-8mm. The spiral deep turning blade 3 uses spiral blades made of 65Mn spring steel. The surface is quenched to a hardness of HRC50-55, which improves the wear resistance of the blades and extends their service life. The comb plate 5 is cut from Q235 steel plate. The number of comb teeth is designed according to the length of the plate, with a spacing of 5cm and a length of 18cm, which is suitable for shallow turning of 15-20cm. The ends of the comb teeth are conical, which makes it easy to insert into the soil to comb out soil clods.

[0019] In a preferred embodiment, the flipping assembly 4 includes a positioning plate 41, a hydraulic cylinder 42, a first connecting plate 43, and a second connecting plate 44. A support plate 6 is fixedly installed on the upper surface of the mounting base 1, and the comb plate 5 is rotatably installed on the top of the support plate 6. The support plate 6 serves as the rotational support foundation for the comb plate 5. It is made of Q235 low carbon steel plate, cut and welded to ensure sufficient load-bearing capacity to support the weight of the comb plate 5 and the soil impact force during operation.

[0020] In a preferred embodiment, a positioning plate 41 is fixedly installed on the outer surface of a support plate 6, and a hydraulic cylinder 42 is rotatably installed on the upper surface of the positioning plate 41. A first connecting plate 43 is rotatably installed at the telescopic end of the hydraulic cylinder 42, and a connecting block 7 is provided at the bottom of the comb plate 5. A second connecting plate 44 is rotatably connected to the outer surface of the connecting block 7. The positioning plate 41 is made of Q235 steel plate and is perpendicularly connected to the support plate 6. A rotating seat is provided on the upper surface of the positioning plate 41, and the end of the hydraulic cylinder 42 is installed on the rotating seat. A hollow rectangular block is movably installed at the telescopic end of the hydraulic cylinder 42, and a round rod 8 passes through the interior of the hollow rectangular block. The connecting block 7, as the transmission medium between the comb plate 5 and the second connecting plate 44, is integrally forged from 40Cr alloy structural steel and requires quenching and tempering treatment after forging. The hardness reaches 25-28 HRC, ensuring sufficient strength and toughness to withstand the impact and torque during operation. The linkage block 7 is rectangular in shape. One end of the second connecting plate 44 is movably installed on the telescopic end of the hydraulic cylinder 42. A round rod 8 is inserted inside the first connecting plate 43 and the second connecting plate 44. The first connecting plate 43 and the second connecting plate 44 are respectively set in a curved shape. The second connecting plate 44 is located inside the first connecting plate 43. There are two first connecting plates 43 and two connecting plates 44, and they are both installed on the round rod 8. The hydraulic cylinder 42 pushes the hollow rectangular block to control the rotation of the round rod 8, thereby driving the first connecting plate 43 and the second connecting plate 44 to rotate, thereby controlling the rotation of the comb plate 5. With the comb teeth facing down, it can be used to turn the soil. The comb teeth lightly turn the soil to retain the surface organic fertilizer.

[0021] The support plate 6 is also equipped with a height adjustment component 9, which is used to control the up and down movement of the comb plate 5. The height adjustment component 9 includes an open rectangular tube 91, a sliding rod 92, and a positioning bolt 93. The open rectangular tube 91 is fixedly installed inside the mounting base 1, and the sliding rod 92 is slidably installed inside the open rectangular tube 91. The open rectangular tube 91 is made of Q235 low carbon steel plate and is rectangular in shape. One side of the open rectangular tube 91 is set with an opening corresponding to the outer surface of the support plate 6, and the opening extends through the top and bottom of the open rectangular tube 91. The sliding rod 92 is integrally formed from 45 steel, and after quenching and tempering, it achieves a hardness of 28-32HRC, which has excellent strength and wear resistance and can withstand long-term sliding friction and load impact. It is rectangular in shape, and the outer surface of the sliding rod 92 slides against the inner wall of the open rectangular tube 91.

[0022] One end of the sliding rod 92 is fixedly connected to the support plate 6 via a connecting rod. A fixing plate 12 with threaded holes is also fixedly installed inside the mounting base 1. A threaded hole is formed on the outer surface of the sliding rod 92, and a positioning bolt 93 is threaded into the inside of the threaded hole. The positioning bolt 93 is threaded into the threaded hole on the fixing plate 12. The connecting rod is made of 40Cr alloy structural steel, integrally forged and machined, and then quenched and tempered at high temperature to achieve a hardness of 28-32 HRC. Two connecting rods are provided, each installed on one side of the sliding rod 92. The rod can pass through the opening of the rectangular tube 91, which can control the support plate 6 to move downward and drive the comb plate 5 to move downward, so that the comb teeth can be inserted into the soil and the soil can be turned. To ensure the stable use of the comb plate 5, after the position of the comb plate 5 is determined, the positioning bolt 93 can be passed through the inside of the sliding rod 92 and screwed into the threaded hole at the corresponding position on the fixed plate 12. One end of the positioning bolt 93 will protrude from the inside of the fixed plate 12 and a nut is screwed on the positioning bolt 93 to position the support plate 6, thereby ensuring the stable use of the comb plate 5.

[0023] The top of the fertilizer box 2 is fitted with a dust cover 10, which covers the top of the fertilizer box 2. The dust cover 10 is made of transparent polycarbonate (PC) sheet. The fertilizer box 2 has a limiting block and a central boss inside, and an elastic buckle on the outside, which can limit the fertilizer box 2 in multiple directions to prevent leakage and displacement. Fertilizer can be added without stopping the machine. The fertilizer box 2 is fixed to the side of the mounting base 1. There are two rubber limiting blocks at the top and bottom inside the box to fit the fertilizer container. The central welded boss has a diameter of 5cm and a height of 3cm, which matches the groove of the fertilizer bag. The outer side is equipped with an elastic buckle to ensure the stable use of the fertilizer box 2.

[0024] The spiral deep turning cutter 3 is mounted on a round shaft at the bottom of the mounting base 1, and a resistance sensing valve 11 is installed at one end of the round shaft. As the core transmission component of the spiral deep turning cutter 3, the round shaft must have high strength, high toughness and good wear resistance. It is made of 40CrNiMoA alloy structural steel forged as a whole. After forging, it is quenched and tempered and then tempered at high temperature. It can withstand the huge torque and impact load generated during soil turning. When the spiral deep turning cutter 3 encounters hard objects while turning the soil, the resistance of the round shaft increases. The resistance sensing valve 11 triggers the spring, and the spring controls the spiral deep turning cutter 3 to move upward to buffer up to 5cm, which can avoid damage to the spiral deep turning cutter 3.

[0025] Specifically, the working process or working principle of an agricultural soil turning device for agricultural planting is as follows: the mounting base 1 is installed on the agricultural machinery, so that the agricultural machinery can be used as a power source to drive the mounting base 1 to move, and the hydraulic pipe on the agricultural machinery is connected to the hydraulic cylinder 42, so that the hydraulic cylinder 42 can be used normally, and the circuit is also connected to the agricultural machinery and powered by the battery on the agricultural machinery.

[0026] When tilling the soil in a field or greenhouse, the agricultural machinery pulls the equipment to the tilling position. When tilling begins, the transmission chain on the agricultural machinery drives the spiral deep tilling blade 3 to rotate, while controlling the hydraulic cylinder 42 to work. The extension end of the hydraulic cylinder 42 extends and drives the first connecting plate 43 to rotate, which in turn drives the second connecting plate 44 to rotate, thereby controlling the linkage block 7 to rotate. This, in turn, pushes the comb plate 5 to flip, so that the side with the comb teeth faces down.

[0027] At this point, the height of the comb plate 5 needs to be adjusted according to the actual soil turning requirements. By moving the sliding rod 92 downward, the comb plate 5 will be moved downward, controlling the depth to which the comb teeth are inserted into the soil. When the predetermined depth is reached, the sliding rod 92 is positioned using the positioning bolt 93, which can position the comb plate 5 and make it stable for use.

[0028] Finally, the equipment is pulled by agricultural machinery to turn the soil, and at the same time, fertilizer will flow out from the inside of fertilizer box 2. The fertilizer will be buried into the root layer by the spiral deep turning blade through the guide channel at the bottom of the outlet of fertilizer box 2, making it easy to use.

[0029] This equipment features layered soil turning and simultaneous fertilizer retention. The comb-tooth plate 5 lightly turns the soil to retain fertilizer, while the spiral deep turning blade 3 deeply turns and breaks up the compacted layer. At the same time, fertilizer is precisely buried into the root layer from the guide channel. The soil turning and fertilization are integrated, which increases fertilizer utilization by 30%, reduces two processes, and increases work efficiency by 40%. Fertilizer can be replenished without stopping the machine. There is no deviation or fertilizer leakage when the soil turning resistance changes. It automatically buffers when encountering hard objects, and the equipment failure rate is reduced by 50%.
