Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an integrated machine for deep application of organic fertilizer and improvement of obstacle soil. Background Technology

[0002] Organic fertilizer, also known simply as "organic fertilizer," refers to a type of fertilizer derived from the metabolic secretions (excrement) and remains of animals and plants, industrial waste (distillery lees, bone meal, and medicinal herb residue), and other biological products (microbial fertilizers). These substances undergo a process of decomposition and fermentation by microorganisms, resulting in a non-toxic and harmless product. Its main characteristics are its rich content of organic matter and various nutrients, enabling it to improve soil nutrient conditions and increase crop yields. It is a sustainable, environmentally friendly, carbon-containing material. Currently, guiding and encouraging farmers to use more organic fertilizer and less chemical fertilizer to restore the natural state of the soil, achieve a virtuous cycle, and improve the soil cultivation environment are crucial for enhancing fertility and efficiency. Traditional methods of applying organic fertilizer, aside from some manual methods of scooping it into furrows, mostly involve spreading it on the surface of the cultivated land. However, this method is subject to wind, sun, and water erosion, leading to significant nutrient loss. Improving the effectiveness of organic fertilizers through scientific means, including changing traditional fertilization methods and replacing surface fertilization with deep underground fertilization, is an important aspect of enhancing fertilizer efficiency.

[0003] The Chinese patent document with authorization announcement number CN222216389U discloses an integrated machine for deep application and deep loosening of organic fertilizer. This integrated machine includes a fertilizer tank, a fertilizer delivery and conveying mechanism, a fertilizer discharge mechanism, and deep tillage blades. The fertilizer tank is fixedly installed on the frame, the fertilizer delivery and conveying mechanism is located below the tank, and the fertilizer delivery and conveying mechanism is used to transport the organic fertilizer in the fertilizer tank to the outside of the fertilizer tank. One end of the fertilizer discharge mechanism is located near the fertilizer delivery and conveying mechanism, and the deep tillage blades are vertically fixed on the frame, with the other end of the deep tillage blades connected to the fertilizer discharge mechanism.

[0004] The structural design of the aforementioned technologies involves a deep-plowing plow in front and a fertilizer pipe behind. During the farming process, if organic fertilizer is to be applied to the edge of the farmland, the deep-plowing plow will inevitably extend beyond the farmland and cut into the field road, causing damage to the field road. Subsequent repairs are required, increasing operating costs and labor time.

[0005] Therefore, an integrated machine for deep application of organic fertilizer and improvement of obstacle soil is proposed to solve the problems mentioned above. Summary of the Invention

[0006] This invention provides an integrated machine for deep application of organic fertilizer and improvement of obstacle soil, aiming to solve the problem of field road damage caused by deep plowing and fertilization in related technologies.

[0007] The present invention provides an integrated machine for deep application of organic fertilizer and improvement of obstacle soil, comprising a frame, a tillage mechanism on the front side of the frame, a telescopic hinge shaft of a tractor connected to the tillage mechanism, the tillage mechanism being able to rise and fall under the drive of the telescopic hinge shaft to insert or remove soil, and a fertilizer application mechanism on the frame. The tillage mechanism has two lifting components, which are hinged to the frame and used to adjust the height of the fertilization mechanism. The fertilization mechanism includes a fertilizer storage box installed on the frame and multiple crushing components connected to the fertilizer storage box. The multiple crushing components are arranged in parallel. Each crushing component includes a rotating drum installed at the bottom of the fertilizer storage box and a spiral blade installed on the outside of the rotating drum. Each pair of adjacent rotating drums and spiral blades rotate in opposite directions. A fertilizer discharge port is opened at the bottom end of the rotating drum. When the tillage mechanism rises and detaches from the soil, the lifting component simultaneously drives the frame to move downward, keeping the rotating drum at the preset soil depth. The spiral blades break up the soil at the boundary of the un-tilled field, while the fertilizer outlet injects fertilizer into the deeper soil layers.

[0008] When deep tilling and fertilizing the soil, the tilling mechanism and the fertilizing mechanism are hinged separately. When the tractor reaches the edge of the field, the tractor drives the tilling mechanism to move upward through the telescopic hinge shaft, so that it is detached from the soil to avoid cutting into the field road. While tilling the land, the opposing spiral blades of the tilling mechanism can generate counter-shearing force to efficiently break up large clumps of soil after deep tilling. As the tilling mechanism moves upward, the lifting component drives the frame to move downward in sync, so that the drum continues to maintain the depth of soil penetration. Since the drum is a columnar structure and the depth remains constant, as the tractor continues to move, in conjunction with the spiral blades, the drum can be brought close to the edge of the field to break up and fertilize the boundary soil that has not been deep tilled.

[0009] Preferably, a fixed frame that is hinged to the tillage mechanism is installed on one side of the top of the frame, and two hinge seats are symmetrically installed on the side of the frame facing the tillage mechanism. A transmission component that is connected to the fertilization mechanism is also installed on the top of the frame, and the transmission component is connected to the rear drive shaft of the tractor through a universal coupling.

[0010] Preferably, the tillage mechanism includes a hinge frame, multiple plow blades, and two hinge seats. One side of the hinge frame is hinged to the telescopic hinge shaft of the tractor, and the two hinge seats are installed on the other side of the hinge frame. The multiple plow blades are symmetrically installed at the bottom of the hinge frame. The top of the hinge frame also has a U-shaped mounting bracket that is hinged to a fixed frame on the frame body. The two lifting components are respectively installed on both sides of the hinge frame.

[0011] The tractor first drives multiple plow blades through the articulated frame to deeply till the soil. After deep tillage, large clumps of soil are then broken up by spiral blades on two rotating drums rotating in opposite directions, which can further improve the soil improvement effect.

[0012] Preferably, the lifting assembly includes a connecting frame, a hydraulic cylinder one, a hydraulic cylinder two, and a hinge seat three. The connecting frame is mounted on the hinge frame. One end of the hydraulic cylinder one is hinged to the connecting frame. One end of the hydraulic cylinder two is hinged to the hinge seat three. The other end of the hydraulic cylinder two is hinged to the frame. The hinge seat three is slidably mounted on the outside of one end of the hydraulic cylinder two. The other end of the hydraulic cylinder one is hinged to the hinge seat three.

[0013] The height of the frame can be adjusted by driving hydraulic cylinder 2 around the hinge point through hydraulic cylinder 1. When the tillage mechanism moves upward, hydraulic cylinder 1 extends and pushes hydraulic cylinder 2 to rotate downward, thereby counteracting the lifting effect of the tillage mechanism on the fertilization mechanism. This ensures that the fertilization mechanism can maintain its insertion depth while the tillage mechanism is detached from the soil, and ensures that the fertilization and crushing operation at the field boundary can be carried out continuously.

[0014] Preferably, the fertilization mechanism further includes a rotating component disposed on one side of the fertilizer storage tank and a stirring shaft rotatably disposed inside the fertilizer storage tank. The rotating component is connected to the stirring shaft and is connected to the transmission component for driving the stirring shaft to rotate in order to stir the fertilizer.

[0015] The rotating assembly drives the stirring shaft to rotate, which can continuously stir and break up the organic fertilizer in the fertilizer storage tank, preventing the fertilizer from clumping due to high humidity or long-term standing, thus avoiding clogging of the rotating drum.

[0016] Preferably, the fertilizer application mechanism further includes a first transmission component, a plurality of feeding components meshing with the first transmission component, and a second transmission component meshing with a plurality of crushing components. The second transmission component is rotatably mounted on the frame and is connected to the transmission component to drive the crushing components to rotate. The first transmission component is located inside the fertilizer storage box and is connected to the second transmission component to drive the feeding components to rotate.

[0017] Preferably, the crushing assembly further includes a receiving seat installed at the bottom of the fertilizer storage box and a second worm gear installed on the outside of the rotating drum. The second worm gear meshes with the second transmission assembly. The top of the rotating drum is rotatably connected to the bottom of the receiving seat. The bottom of the rotating drum is conical, and multiple fertilizer discharge ports are opened on the outside of its bottom end.

[0018] The cone-shaped rotating drum at the bottom allows it to penetrate the soil more effectively for deep fertilization. During fertilization, fertilizer enters the rotating drum from the storage tank and is discharged from the discharge port at the bottom. Since the discharge port is located in the center of the crushing area, the fertilizer is directly mixed into the already crushed fine soil, avoiding the fertilizer remaining on the surface of large soil clods and failing to penetrate the soil layer, thus achieving deep and precise fertilization.

[0019] Preferably, there are two transmission components, which are connected to each other. One transmission component meshes with a worm gear on a forward-rotating drum, and the other transmission component meshes with a worm gear on a reverse-rotating drum.

[0020] Preferably, the feeding assembly includes a worm gear and a screw. The worm gear is rotatably connected inside the fertilizer storage box and meshes with a transmission assembly. The screw is coaxially connected to the worm gear and extends downward into the rotating drum. Its outer circumferential surface contacts the inner wall of the rotating drum to transport the fertilizer storage box into the rotating drum.

[0021] When the screw rotates inside the drum, its outer circumference and the inner wall of the drum form a forced conveying channel, which exerts downward pressure on the fertilizer to overcome the external pressure of the soil on the fertilizer outlet and prevent the fertilizer outlet from being blocked by moist soil.

[0022] Preferably, the transmission assembly includes a mounting base installed above the inside of the fertilizer storage tank and a worm gear rotatably connected to the mounting base, the worm gear meshing with a worm wheel in one of the plurality of feeding assemblies.

[0023] The beneficial effects of this invention, achieved by adopting the above technical solution, are as follows: When deep tilling and fertilizing the soil, the tilling mechanism and the fertilizing mechanism are hinged separately. When the tractor reaches the edge of the field, the tractor drives the tilling mechanism upward through its telescopic hinge shaft, causing it to detach from the soil and avoid cutting into the field road. While tilling the land, the opposing spiral blades of the tilling mechanism generate opposing shearing forces to efficiently break up large clumps of soil after deep tilling. As the tilling mechanism moves upward, the lifting component simultaneously drives the frame downward so that the rotating drum remains at the soil depth. Since the rotating drum is a columnar structure and its depth remains constant, as the tractor continues to move, in conjunction with the spiral blades, the rotating drum can be brought close to the edge of the field to break up and fertilize the un-tilled boundary soil. This achieves comprehensive deep tilling and fertilization of the field while avoiding damage to the field road by the tilling mechanism, thus reducing operating costs and labor time.

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] like Figures 1 to 7 As shown, the integrated machine for deep application of organic fertilizer and improvement of obstacle soil of the present invention includes a support mechanism 10, a tillage mechanism 20, and a fertilization mechanism 30. The fertilization mechanism 30 is mounted on the support mechanism 10, and the tillage mechanism 20 is hinged to the support mechanism 10 and located on the front side of the support mechanism 10. The fertilization mechanism 30 is capable of breaking up large clumps of soil after deep tillage. The support mechanism 10 is connected to the rear drive shaft of the tractor via a universal coupling, and the tillage mechanism 20 is connected to a telescopic hinge shaft on the tractor.

[0034] During deep tillage, the tractor lowers the tillage mechanism 20 via its telescopic articulated shaft, inserting it into the soil. Once inserted, the tractor moves the tillage mechanism 20 to further till the soil. Subsequently, the tillage mechanism 20 lowers the support mechanism 10, allowing the fertilization mechanism 30 to be inserted into the tilled soil for further breaking up and fertilizing. As the tractor moves to the edge of the field, it continues to move, allowing the tillage mechanism 20 to further till the edge area. When the tillage mechanism 20 reaches the field boundary, the tractor raises it via its telescopic articulated shaft to prevent further movement from damaging the road surface. During this upward movement, the position of the fertilization mechanism 30 within the soil is maintained. As the tractor continues to move, the fertilization mechanism 30 breaks up and fertilizes the soil at the field boundary.

[0035] The support mechanism 10 includes a frame 11, a support plate 12, a hinge seat 13, and a transmission component. A fixed frame, hinged to the tillage mechanism 20, is mounted on one side of the top of the frame 11. The support plate 12 is installed inside the frame 11. There are two hinge seats 13, symmetrically mounted on the side of the frame 11 facing the tillage mechanism 20 and hinged to it. The transmission component is mounted on top of the frame 11 and located below the fixed frame; the transmission component is connected to the fertilization mechanism 30.

[0036] The transmission components include a transmission housing 14, output shafts 15, and drive wheels 16. The transmission housing 14 is mounted on top of the frame 11. There are two output shafts 15 and two drive wheels 16. One end of each output shaft 15 is connected to one of the two output ends of the transmission housing 14, and the other end is mounted on the inside of each drive wheel 16. Both drive wheels 16 are connected to the fertilizer applicator 30. The input end of the transmission housing 14 is connected to the rear drive shaft of the tractor via a universal coupling.

[0037] The tractor can drive the transmission box 14 through the universal coupling. At this time, the transmission box 14 can drive the transmission wheel 16 to rotate through the output shaft 15, thereby driving the fertilizer applicator 30 to operate.

[0038] The tillage mechanism 20 includes an articulated frame 21, plow blades 22, articulated base 23, lifting assembly 24, articulated base 25, and articulated rod 26. The articulated frame 21 consists of two crossbeams and a U-shaped mounting bracket, with the universal coupling connected to the tractor located inside the U-shaped mounting bracket. Multiple plow blades 22 are symmetrically mounted at the bottom of the articulated frame 21. There are two articulated bases 23, two lifting assemblies 24, and two articulated bases 25. Two articulated bases 23 are symmetrically mounted on the side of the articulated frame 21 facing away from the frame 11, and two articulated bases 25 are symmetrically mounted on the side of the articulated frame 21 facing the frame 11. The tractor hinges to the two articulated bases 23 via its two telescopic articulation shafts, thereby driving the articulated frame 21 to move up and down. It should be noted that the telescopic articulation shafts on the tractor are existing hydraulic telescopic shafts, the specific structure of which will not be described in detail here. Two lifting components 24 are respectively installed on the top sides of the hinge frame 21 and are respectively hinged to the two hinge seats 13 to drive the frame 11 to rise and fall. One end of the hinge rod 26 is hinged to the top of the U-shaped mounting bracket of the hinge frame 21, and the other end of the hinge rod 26 is hinged to the fixed frame of the frame 11.

[0039] The lifting assembly 24 includes a connecting frame 241, a first hydraulic cylinder 242, a second hydraulic cylinder 243, and a third hinge seat 244. The connecting frame 241 is mounted on the top side of the hinge frame 21, and the fixed end of the first hydraulic cylinder 242 is hinged to the top of the connecting frame 241. The fixed end of the second hydraulic cylinder 243 is hinged to the fourth hinge seat 25, and the movable end of the second hydraulic cylinder 243 is hinged to the first hinge seat 13. The third hinge seat 244 is slidably mounted on the outside of the fixed end of the second hydraulic cylinder 243, and the movable end of the first hydraulic cylinder 242 is hinged to the third hinge seat 244.

[0040] When the fertilizing mechanism 30 needs to be lowered, the movable end of hydraulic cylinder 242 extends and drives hydraulic cylinder 243 to rotate downward around hinge seat 25. At the same time, hydraulic cylinder 243 drives the fertilizing mechanism 30 downward through frame 11, so that the fertilizing mechanism 30 is inserted into the deeply tilled soil. When the tilling mechanism 20 moves upward, the telescopic hinge shaft on the tractor drives the tilling mechanism 20 upward. During the upward movement of the tilling mechanism 20, the movable end of hydraulic cylinder 242 extends outward again, so that hydraulic cylinder 243 continues to rotate downward, ensuring that the fertilizing mechanism 30 remains in the deeply tilled soil and performs fertilization.

[0041] The fertilization mechanism 30 includes a fertilizer storage tank 31, a stirring shaft 32, a rotating assembly 33, a first transmission assembly 34, a feeding assembly 35, a crushing assembly 36, and a second transmission assembly 37. The fertilizer storage tank 31 is installed on top of the frame 11 and is used to store organic fertilizer. There are two stirring shafts 32, which are symmetrically arranged inside the fertilizer storage tank 31 to stir and crush the organic fertilizer. The rotating assembly 33 is located on one side of the fertilizer storage tank 31 and connected to the two stirring shafts 32 to drive them to rotate relative to each other. There are two second transmission assemblies 37, which are connected to each other. The two second transmission assemblies 37 are respectively located on both sides of the bottom of the support plate 12 and are rotatably connected to the frame 11. A first transmission wheel 16 on one output shaft 15 is connected to the rotating assembly 33, and a first transmission wheel 16 on the other output shaft 15 is connected to one of the second transmission assemblies 37.

[0042] A transmission assembly 34 is located inside the fertilizer storage box 31 at its upper part, and is also connected to one of the transmission assemblies 37. There are multiple feeding assemblies 35 and multiple crushing assemblies 36. Multiple feeding assemblies 35 are evenly spaced on the transmission assembly 34 and mesh with it. Multiple crushing assemblies 36 are evenly spaced at the bottom of the fertilizer storage box 31 and located between two transmission assemblies 37. Each pair of adjacent crushing assemblies 36 rotates in opposite directions. The two transmission assemblies 37 mesh with multiple crushing assemblies 36 respectively. The bottom end of the feeding assembly 35 penetrates the fertilizer storage box 31 and extends into the interior of the crushing assembly 36. The bottom end of the crushing assembly 36 has an opening for fertilizer discharge.

[0043] During fertilization, the transmission box 14 drives the rotating component 33 and the second transmission component 37 via the transmission wheels 16 on the two output shafts 15. The second transmission component 37 also drives the first transmission component 34 to operate synchronously. During operation, the rotating component 33 drives the two stirring shafts 32 to rotate relative to each other, thereby stirring the fertilizer in the fertilizer storage box 31 and preventing it from clumping. During operation, the second transmission component 37 simultaneously drives multiple crushing components 36 to rotate, crushing large clumps of soil after deep tillage. During operation, the first transmission component 34 drives multiple feeding components 35 to rotate simultaneously, conveying the fertilizer from the fertilizer storage box 31 to the bottom of the crushing component 36, where the fertilizer is discharged, achieving a deep fertilization effect.

[0044] The rotating assembly 33 includes a connecting shaft 331, a transmission wheel 332, a rotating shaft 333, a transmission wheel 334, a gear 335, a connecting shaft 336, and a gear 337. One end of the connecting shaft 331 and the connecting shaft 336 are respectively mounted on one end of the two stirring shafts 32, and the other ends of the connecting shafts 331 and 336 both pass through the fertilizer storage tank 31 and extend to the outside of the fertilizer storage tank 31. The transmission wheel 332 and the gear 337 are respectively mounted on the ends of the connecting shafts 331 and 336 that extend out of the fertilizer storage tank 31. The transmission wheel 332 is connected to the transmission wheel 16 on the output shaft 15 via a belt. One end of the rotating shaft 333 is rotatably connected to one side of the fertilizer storage tank 31. The transmission wheel 334 is mounted on the outside of the other end of the rotating shaft 333 and is connected to the transmission wheel 332 via a belt. The gear 335 is mounted on the other end of the rotating shaft 333 and meshes with the gear 337.

[0045] When the output shaft 15 rotates, the transmission wheel 16 drives the connecting shaft 331 and the rotating shaft 333 to rotate through the transmission wheel 332. The rotating shaft 333 drives the connecting shaft 336 to rotate through the gear 335, thereby driving the two stirring shafts 32 to rotate relative to each other.

[0046] The transmission assembly 34 includes a mounting base 341, a worm gear 342, and a transmission wheel 343. The mounting base 341 is installed inside the fertilizer storage box 31. One end of the worm gear 342 is rotatably connected to one side of the inner wall of the mounting base 341, and the other end of the worm gear 342 passes through the fertilizer storage box 31 and extends to the outside of the fertilizer storage box 31. The transmission wheel 343 is installed at the other end of the worm gear 342 and is connected to one of the transmission assemblies 37.

[0047] The feeding assembly 35 includes a worm gear 351 and a screw 352. The worm gear 351 is rotatably connected to the inner bottom wall of the mounting base 341 and meshes with the worm gear 342. The top end of the screw 352 is mounted on the worm gear 351. A hole is provided on the inner bottom wall of the fertilizer storage box 31 for the screw 352 to pass through. The bottom end of the screw 352 passes through the hole on the fertilizer storage box 31 and extends into the interior of the crushing assembly 36.

[0048] When the worm gear 342 rotates, the worm wheel 351 drives the screw 352 to rotate inside the fertilizer storage box 31, thereby driving the organic fertilizer in the fertilizer storage box 31 to enter the crushing component 36 through the hole of the fertilizer storage box 31, which can prevent the fertilizer from clogging the hole.

[0049] Transmission assembly 2 37 includes worm gear 2 371 and transmission wheel 5 372. Worm gear 2 371 is located at the bottom of support plate 12 and is rotatably connected to frame 11. Its other end passes through frame 11 and extends to the outside of frame 11. Transmission wheel 5 372 is installed at the end of worm gear 2 371 that passes through frame 11. The transmission wheels 5 372 on the two transmission assemblies 2 37 are connected by belt drive. Transmission wheel 1 16 on output shaft 15 is connected to one of the transmission wheels 5 372 by belt drive. The other transmission wheel 5 372 is connected to transmission wheel 4 343 by belt drive.

[0050] The crushing assembly 36 includes a rotating drum 361, a receiving seat 362, spiral blades 363, and a worm gear 364. The receiving seat 362 is installed at the bottom of the fertilizer storage tank 31 and corresponds to a hole on the tank to receive organic fertilizer discharged from it. The top of the rotating drum 361 is rotatably connected to and communicates with the bottom of the receiving seat 362. The bottom end of the rotating drum 361 passes through the support plate 12 and extends to the outside of the plate. The support plate 12 and the rotating drum 361 are rotatably connected. The outer wall of the screw 352 contacts the inner wall of the rotating drum 361. The bottom end of the rotating drum 361 is conical, and multiple discharge ports 365 for discharging organic fertilizer are provided on its outer periphery. The spiral blades 363 are installed on the outer side of the bottom end of the rotating drum 361 to facilitate drilling the drum 361 into the ground. The spiral blades 363 on adjacent rotating drums 361 rotate in opposite directions.

[0051] Worm gear 364 is mounted on the outside of the rotating drum 361 and below the support plate 12. Worms 371 on the two transmission components 37 are respectively arranged on both sides of worm gear 364 on the multiple crushing components 36. One worm gear 371 meshes with the forward-rotating worm gear 364, and the other worm gear 371 meshes with the reverse-rotating worm gear 364, so that the rotation directions of the two adjacent rotating drums 361 are opposite, thereby causing the spiral blades 363 on the two adjacent rotating drums 361 to crush large pieces of soil.

[0052] Working principle: When deep tilling and fertilizing the soil, the tractor uses its telescopic articulation shaft to insert the plow blades 22 on the articulated frame 21 into a boundary of the field and move the plow blades 22 to perform deep tillage. When the rotating drum 361 reaches the boundary of the field, the movable end of hydraulic cylinder 1 242 extends and drives hydraulic cylinder 243 to rotate downward around the articulated seat 4 25. At the same time, hydraulic cylinder 243 drives multiple rotating drums 361 to move downward through the support plate 12 on the frame 11, so that the rotating drums 361 are inserted into the deeply tilled soil.

[0053] During the process of inserting the rotating drum 361 into the soil, the transmission box 14 drives the two stirring shafts 32 and the two worm gears 371 to rotate through the transmission wheels 16 on the two output shafts 15 respectively. At the same time, the worm gears 371 drive the worm gears 342 on the transmission wheel 343 to rotate synchronously through the transmission wheel 372.

[0054] During rotation, the two stirring shafts 32 crush and agitate the fertilizer in the fertilizer storage tank 31, preventing it from clumping. The two worm gears 371, during rotation, drive multiple rotating drums 361, which in turn drive the spiral blades 363 on them, thus breaking up large clumps of soil after deep tillage. While the spiral blades 363 are breaking up the soil, the worm gear 342 drives the screw 352 to rotate inside the fertilizer storage tank 31, drawing organic fertilizer from the tank into the rotating drums 361 and out through the fertilizer discharge port 365, thus fertilizing the soil. During fertilization, the extrusion force of the screw 352 prevents soil from clogging the discharge port 365, ensuring the normal discharge of fertilizer.

[0055] When the plow blade 22 moves to the other boundary of the field, the telescopic articulation shaft on the tractor drives the plow blade 22 on the articulated frame 21 to move upward, removing the plow blade 22 from the soil to prevent it from cutting into the field road and causing damage. As the articulated frame 21 moves upward, the movable end of hydraulic cylinder 242 extends outward again, causing hydraulic cylinder 243 to continue rotating downward, ensuring that the rotating drum 361 remains in the deeply tilled soil. After the plow blade 22 is removed from the soil, the tractor continues to move, driving the rotating drum 361 to continue moving in the field. When the rotating drum 361 moves to the field boundary, due to its columnar shape, it can stay close to the edge of the field without cutting into the field road, breaking up the soil not deeply tilled by the plow blade 22. This achieves the effect of comprehensive fertilization of the field without damaging the field road. After fertilization is completed, hydraulic cylinder 242, through hydraulic cylinder 243, lifts the frame 11, thereby removing the rotating drum 361 from the soil for subsequent operations.

[0056] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

The fertilization mechanism includes a fertilizer storage box mounted on a frame, multiple crushing components connected to the fertilizer storage box, a transmission component one, multiple feeding components meshing with the transmission component one, and a transmission component two meshing with the multiple crushing components. The multiple crushing components are arranged in parallel. The transmission component two is rotatably mounted on the frame and is connected to a transmission component to drive the crushing components to rotate. The transmission component one is located inside the fertilizer storage box and is connected to the transmission component two to drive the feeding components to rotate. The crushing assembly includes a rotating drum rotatably mounted at the bottom of the fertilizer storage box, a receiving seat mounted at the bottom of the fertilizer storage box, and spiral blades and worm gear II mounted on the outside of the rotating drum. Each pair of adjacent rotating drums and spiral blades rotate in opposite directions. There are two transmission assemblies II, which are connected to each other. One transmission assembly II meshes with the worm gear II on the rotating drum in the forward direction, and the other transmission assembly II meshes with the worm gear II on the rotating drum in the reverse direction. The top of the rotating drum is rotatably connected to the bottom of the receiving seat. The bottom of the rotating drum is conical, and multiple fertilizer discharge ports are opened on the outer side of its bottom end. The feeding assembly includes a worm gear and a screw. The worm gear is rotatably connected inside the fertilizer storage box and meshes with the transmission assembly. The screw is coaxially connected to the worm gear and extends downward into the rotating drum. Its outer circumferential surface contacts the inner wall of the rotating drum to transport the organic fertilizer in the fertilizer storage box into the rotating drum. When the tillage mechanism rises and detaches from the soil, the lifting component simultaneously drives the frame to move downward, keeping the rotating drum at the preset soil depth. The spiral blades break up the soil at the boundary of the un-tilled field, while the fertilizer outlet injects fertilizer into the deeper soil layers.
