Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, and in particular to a deep tillage fertilization device. Background Technology

[0002] With agricultural development, some land inevitably suffers from soil compaction and nutrient loss (such as nitrogen, phosphorus, and potassium) due to long-term cultivation. To address these issues, deep plowing to break down physical barriers, combined with fertilization to replenish nutrients, has become a crucial method for improving soil structure and enhancing fertility. Deep plowing and fertilization break up the plow pan, increasing the thickness of the topsoil layer and creating a loose, well-aerated growing environment for roots. Simultaneously, deep fertilization stimulates root growth into deeper soil layers, improving water and nutrient absorption. Furthermore, deep plowing promotes the decomposition of organic matter, and when combined with measures such as returning straw to the field, it increases soil organic matter content and water and fertilizer retention capacity, providing a continuous supply of nutrients for crops.

[0003] In related technologies, fertilizer is applied to planting pits manually or using digging machinery to achieve deep fertilization, but this method is inefficient. Furthermore, the planting pits are spaced apart, requiring workers to repeatedly move the digging equipment, making the operation cumbersome. Additionally, because the planting pits are not interconnected, uneven fertilization can occur, affecting planting results. Summary of the Invention

[0004] The main purpose of this invention is to provide a deep tillage and fertilization device, which aims to improve the efficiency of deep tillage and fertilization while making the fertilization more uniform and improving the planting effect.

[0005] To achieve the above objectives, the present invention proposes a deep tillage and fertilization device, comprising: frame; The moving mechanism includes a plurality of casters spaced apart on the frame; A trenching mechanism, comprising a trenching drive component and a trenching chain mounted on the frame, the trenching chain being drively connected to the trenching drive component; and The fertilization mechanism includes a hopper, a feeding screw, a fertilization drive, and a fertilization pipe. The fertilization drive and the hopper are mounted on the frame. The hopper forms a storage trough, a feeding trough, and a discharge port. The feeding trough is connected to the storage trough and the discharge port. The discharge port extends through the bottom of the hopper. The feeding screw is disposed in the feeding trough and is connected to the fertilization drive. The fertilization pipe is connected to the discharge port and extends along the length of the trenching chain.

[0006] In an optional embodiment, the fertilizer application pipe includes a limiting rod and a feeding hose. One end of the limiting rod is rotatably connected to the frame and has a limiting groove. The feeding hose is partially disposed in the limiting groove and communicates with the discharge port. The feeding hose is connected to the limiting rod.

[0007] In an optional embodiment, the fertilizer pipe further includes a fixing pin, the limiting rod has a limiting hole, the frame has a fixing hole, and the limiting rod can rotate relative to the frame so that the fixing pin is inserted into the limiting hole and the fixing hole to limit and fix the limiting rod and the frame.

[0008] In an optional embodiment, the fertilizer application mechanism further includes a reset member connected to the hopper and the limiting rod.

[0009] In an alternative embodiment, the reset element includes two reset springs connected to the limiting rod and the hopper, the two reset springs providing elastic force to make the limiting rod and the frame parallel to each other.

[0010] In an optional embodiment, the fertilizer application drive includes a fertilizer application drive motor and a coupling, the fertilizer application drive motor being mounted on the frame, and the coupling being connected to the output shaft of the fertilizer application drive motor and the feeding screw.

[0011] In an optional embodiment, the fertilizer application drive further includes two mounting bearings disposed within the feeding trough, and the two ends of the feeding screw are respectively fitted into the bearing holes of the mounting bearings.

[0012] In an optional embodiment, the trenching drive includes a trenching drive motor, a drive wheel, a driven wheel, and a transmission chain. The trenching drive motor is mounted on the frame, the drive wheel is sleeved on the output shaft of the trenching drive motor, the driven wheel is connected to the trenching chain, and the transmission chain is sleeved on the outside of the drive wheel and the driven wheel.

[0013] In an optional embodiment, the trenching mechanism further includes a reduction gearbox mounted on the frame and connected to the trenching drive motor and the trenching chain drive.

[0014] In an optional embodiment, the trenching mechanism further includes a soil-discharging screw, which is connected to the drive motor and extends toward the width of the frame. This utility model's technical solution employs a frame; multiple moving wheels of the moving mechanism are spaced apart on the frame; the trenching chain of the trenching mechanism is driven and connected to the trenching drive; the fertilization drive and hopper of the fertilization mechanism are installed on the frame. The hopper forms a storage trough, a feeding trough, and a discharge port. The feeding trough is connected to the storage trough and the discharge port. The discharge port penetrates through the bottom of the hopper. The feeding screw is located in the feeding trough and is driven and connected to the fertilization drive. The fertilization pipe is connected to the discharge port and extends along the length of the trenching chain.

[0015] In this embodiment, the ditching drive unit drives the ditching chain to rotate relative to the frame, so that the ditching chain, which is in contact with the soil surface, digs trenches of a certain depth and width in the soil. These trenches can be used to plant specific crops or as fertilizer pits for pre-storing fertility. As the ditching chain rotates, the frame moves in the direction of rotation of the ditching chain, realizing self-propelled ditching. During the ditching process, fertilizer is stored in the storage trough of the hopper. The fertilizer application drive unit drives the feeding screw to rotate, so that the fertilizer enters the feeding trough and is conveyed to the discharge port side. Then, it enters the fertilizer application pipe from the discharge port and is spread into the pre-dug trenches through the fertilizer application pipe. In this application, by setting up a ditching mechanism, the efficiency of tilling and deep plowing can be greatly improved. By setting up a fertilizer application mechanism, fertilizer can be spread into the trenches simultaneously. Since the trenches are continuously extended, the fertilizer spread in the area is more sufficient, the soil absorption is more uniform, and the growth effect of subsequent crops is better.

[0022] Reference Figures 1 to 6 This utility model proposes a deep tillage and fertilization device 100.

[0023] In this embodiment of the utility model, the deep tillage and fertilization equipment 100 includes a frame 10; a moving mechanism 20 including a plurality of moving wheels 21 spaced apart on the frame 10; a ditching mechanism including a ditching drive component 31 and a ditching chain 32 mounted on the frame 10, the ditching chain 32 being drivenly connected to the ditching drive component 31; and a fertilization mechanism 40 including a hopper 41, a feeding screw 42, a fertilization drive component 43, and a fertilization pipe 44, the fertilization drive component 43 and the hopper 41 being mounted on... On the frame 10, the hopper 41 forms a storage trough 41a, a feeding trough 41b, and a discharge port 41c. The feeding trough 41b is connected to the storage trough 41a and the discharge port 41c. The discharge port 41c penetrates through the bottom of the hopper 41. The feeding screw 42 is disposed in the feeding trough 41b and is connected to the fertilizer driving component 43. The fertilizer pipe 44 is connected to the discharge port 41c and extends along the length direction of the trenching chain 32.

[0024] Specifically, in this application, the frame 10 is formed by splicing metal profiles together using screws and welding processes. The moving mechanism 20 includes three casters 21, which are rotatably connected to the lower part of the frame 10, making it easier and more convenient for workers to move the frame 10.

[0025] Please see again Figure 4 The ditching mechanism includes a ditching drive component 31 and a ditching chain 32 mounted on the frame 10. The ditching drive component 31 includes a ditching drive motor 311, a drive wheel 312, a driven wheel 313, and a transmission chain 314. The ditching drive motor 311 is a diesel motor mounted on the frame 10. The drive wheel 312 is sleeved on the output shaft of the ditching drive motor 311. The driven wheel 313 is connected to the ditching chain 32. The transmission chain 314 is sleeved on the outside of the drive wheel 312 and the driven wheel 313. Driven by the ditching drive motor 311, the ditching chain 32 rotates along the ditching direction. During its rotation, the teeth on the ditching chain 32 repeatedly rub against the ground, causing one end away from the frame 10 to extend into the ground under gravity, forming a ditch of a certain width. Under the action of this friction, the frame 10 moves independently on the cultivated land.

[0026] Furthermore, in this application, the ditching drive component 31 includes multiple driven wheels 313 and multiple transmission chains 314. The ditching mechanism also includes a reduction gearbox 33 and a soil-discharging screw 34. The reduction gearbox 33 is mounted on the frame 10 and is composed of multiple meshing gears (not shown). The soil-discharging screw 34 is rotatably connected to the frame 10. Driven wheels 313 are respectively mounted on the reduction gearbox 33 and the soil-discharging screw 34. The driven wheels 313 are interconnected through the transmission chains 314 to transmit the output speed of the ditching drive motor 311. The reduction gearbox 33 is used to further increase the output torque of the ditching drive motor 311, and the soil-discharging screw 34 is used to promptly discharge the soil scattered around the frame 10 after ditching to the outside of the frame 10, thereby ensuring the smooth operation of the deep tillage and fertilization equipment 100. The specific structure and working principle of the ditching mechanism have been widely applied in actual farming and will not be elaborated further here.

[0027] It is understandable that the trenching drive unit 31 can be used not only to open trenches for planting crops, but also to turn over and loosen the soil, and its application is not limited.

[0028] In this embodiment, the ditching drive 31 drives the ditching chain 32 to rotate relative to the frame 10, so that the ditching chain 32, which is in contact with the soil surface, digs trenches of a certain depth and width in the soil. These trenches can be used to plant specific crops or as fertilizer pits for pre-storing fertility. As the ditching chain 32 rotates, the frame 10 moves along the direction of rotation of the ditching chain 32, realizing self-propelled ditching. During the ditching process, fertilizer is stored in the storage trough 41a of the hopper 41. The fertilizer application drive 43 drives the feeding screw 42 to rotate, so that the fertilizer enters the feeding trough 41b and is conveyed to the discharge port 41c side. Then, it enters the fertilizer application pipe 44 from the discharge port 41c and is spread into the pre-dug trenches from the fertilizer application pipe 44. In this application, by setting up a ditching mechanism, the efficiency of tilling and deep plowing can be greatly improved. By setting up the fertilization mechanism 40, fertilizer can be simultaneously applied into the trench. Since the trench extends continuously, the fertilizer applied in the area is more fully applied, the soil absorbs it more evenly, and the subsequent crops grow better.

[0029] It is understood that the fertilizer used by the deep tillage fertilization equipment 100 in this application can be industrial fertilizer or biological fertilizer, and no specific limitation is made here.

[0030] Please see again Figures 4 to 6In the normal state, that is, in the working state before trenching, the trenching chain 32 and the fertilizer pipe 44 extend horizontally. In the working state, the trenching chain 32 and the fertilizer pipe 44 extend at an angle. This is to facilitate the switching between the two states of the fertilizer pipe 44, and to ensure that the fertilizer falls relatively completely into the trench. In this embodiment, the fertilizer pipe 44 includes a limiting rod 441 and a feeding hose 442. Specifically, one end of the limiting rod 441 is rotatably connected to the frame 10 via a mounting shaft, and the other end extends away from the frame 10. The portion extending away from the frame 10 is machined to form a limiting groove with an arc-shaped cross-section. The feeding hose 442 is made of polypropylene or polyethylene and has a certain elastic deformation capability. The feeding hose 442 is partially set in the limiting groove and connected to the discharge port 41c. The feeding hose 442 is connected to the limiting rod 441 by cable ties, straps, or glue. Under the action of external force, the limiting rod 441 and the feeding hose 442 can swing with the frame 10, switching between the normal state and the working state.

[0031] Please see again Figure 2 In this embodiment, the fertilizer pipe 44 also includes a fixing pin 443. The limiting rod 441 has a limiting hole (not shown), and the frame 10 has a corresponding fixing hole (not shown). When the deep tillage fertilization equipment 100 is in working condition, the limiting rod 441 can swing downward, so that the fixing pin 443 is inserted into the limiting hole and the fixing hole, limiting and fixing the limiting rod 441 and the frame 10. In this way, under the action of gravity, the fertilizer falls into the pre-drilled trench from the inclined feeding hose 442, which can minimize fertilizer waste and improve fertilization efficiency.

[0032] In this application, the fertilization mechanism 40 also includes a reset component, which includes two reset springs 45 connected to the limiting rod 441 and the hopper 41. In actual use, after the trench is opened, the fixing pin 443 can be pulled out from the limiting hole and the fixing hole. Under the elastic force of the two reset springs 45, the limiting rod 441 swings towards the upper part of the frame 10 and is set parallel to the frame 10 in the horizontal direction, and is also set parallel to the extension direction of the trenching chain 32. In this way, the storage operation of the fertilizer pipe 44 is more labor-saving, and it can also avoid the safety accidents caused by manual operation. The safety factor of the deep tillage fertilization equipment 100 is higher.

[0033] Please see again Figure 4In this application, the fertilizer application drive component 43 includes a fertilizer application drive motor 431, a coupling (not shown), and two mounting bearings 432. The fertilizer application drive motor 431 is mounted on the frame 10. Two through holes communicating with the feeding trough 41b are opened on both sides of the hopper 41. The two mounting bearings 432 are respectively inserted into the through holes. The two ends of the feeding screw 42 are respectively sleeved in the bearing holes of the mounting bearings 432, so that the feeding screw 42 is rotatably connected to the hopper 41. One end of the feeding screw 42 is connected to the output shaft of the fertilizer application drive motor 431 through the coupling. Under the drive of the fertilizer application drive motor 431, the feeding screw 42 rotates in the feeding trough 41b, feeding fertilizer from the storage tank 41a into the feeding trough 41b, and then from the feeding trough 41b to the discharge port 41c.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
