Description

Technical Field

[0001] This application relates to the field of rotary tiller technology, and in particular to a contour-following automatic leveling rotary tiller. Background Technology

[0002] In agricultural production, rotary tillers, as important tillage machinery, play a crucial role in improving soil quality and creating favorable conditions for subsequent operations such as sowing. However, traditional rotary tillers have many shortcomings in practical applications; Traditional rotary tillers typically have a fixed-connection flat plate structure. When faced with complex and varied terrain, such as bumps or depressions, the angle cannot be adjusted flexibly, making it difficult to maintain a constant contact with the ground. This results in poor ground flatness and affects the quality of subsequent sowing. Meanwhile, during rotary tillage, a large amount of soil, weeds, and other debris easily adheres to the surface of the leveling plate. If not cleaned in time, this will interfere with the normal operation of the leveling plate and further reduce the leveling effect of the ground. Moreover, traditional equipment lacks effective cleaning and soil management functions, and cannot perform operations such as uniformly compacting the soil and breaking up large soil clods, which is not conducive to seed germination and plant root growth. Therefore, a contour-following automatic leveling rotary tiller is proposed to solve the problems mentioned above. Summary of the Invention

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention achieves active cleaning through mechanical high-frequency tapping, solving the problem of wet and sticky soil adhering to the smoothing plate. It avoids the impact of soil accumulation on the operation and the increase of traction resistance caused by traditional machines. Furthermore, the tapping point is located on the back of the smoothing plate and does not come into direct contact with the soil, thus preventing the cleaning mechanism itself from being jammed by soil.

[0015] 2. This invention, by controlling the extension and retraction of the telescopic rod, can adjust the relative position of the reciprocating plate and the rotating drum, thereby changing the amplitude of their reciprocating motion.

It achieves adjustment according to working conditions and has strong adaptability.

[0016] 3. In this invention, the reciprocating plate indirectly drives the infusion assembly during movement.

[0018] 5. In this invention, the reciprocating plate drives the gears and stirring rod to rotate in both directions via the toothed plate, thereby automatically stirring the liquid in the storage tank, preventing sedimentation, and ensuring uniform concentration and consistent spraying effect.

[0022] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0023] Example 1, such as Figures 1 to 3As shown, this is the first embodiment of the present invention, which provides a contour-following automatic leveling rotary tiller, including a rotary tiller body 1. The rotary tiller body 1 includes: a housing 11, a base 12, a leveling plate 13, a blade 14, and an interior of the housing 11. Specifically, the base 12 is fixed to the top side of the housing 11 and is used to connect to a vehicle body; the leveling plate 13 is hinged to one side of the housing 11; the blade 14 is rotatably disposed inside the housing 11; a drive device 15 and a hydraulic telescopic rod 16 are both disposed above the housing 11; wherein, the hydraulic telescopic rod 16 is hinged to the outer wall of the base 12, and the hydraulic... The output end of the telescopic rod 16 is hinged to the outside of the leveling plate 13, thereby achieving automatic leveling of the leveling plate 13. This allows for better contact with the ground, leveling the tilled surface and improving its flatness, providing a good foundation for subsequent operations such as sowing. It should be noted that because the leveling plate 13 is hinged to one side of the machine housing 11, it provides a flexible pivot point, allowing it to swing freely according to the undulations of the ground. When the rotary tiller is working in the field and encounters bumps or depressions, the leveling plate 13 will not be forced to maintain a fixed angle with the ground like a fixed connection structure. Instead, it can rotate around the hinge point, always trying to keep in contact with the ground as much as possible. For example, when encountering a bump, the leveling plate 13 rotates upwards; when encountering a depression, it rotates downwards, thus mimicking different terrain contours and providing a basis for subsequent leveling work.

[0024] To achieve the output of the cutting tool 14, the drive device 15 consists of a motor, a transmission belt, and a transmission wheel. A shield can also be installed on the outside of the housing 11 to protect the drive device 15. The cutting tool 14 includes a rotating shaft 141, a tool holder 142 bolted to the outer surface of the rotating shaft 141, and several cutting blades 143 fixed to the outer surface of the tool holder 142. There are multiple tool holders 142. The bearing of the rotating shaft 141 is installed inside the housing 11.

[0025] Example 2, as Figures 1 to 4 and Figure 6As shown, this is the second embodiment of the present invention, which differs from the first embodiment in that: a cleaning mechanism 2 is provided on the leveling plate 13. This cleaning mechanism 2 can promptly remove soil, weeds, and other debris adhering to the surface of the leveling plate 13 during rotary tillage operations. This prevents the accumulation of these debris from affecting the normal operation of the leveling plate 13, ensuring that the leveling plate 13 always maintains good contact with the ground, achieving precise automatic leveling and effective flattening of the ground, thus improving the quality of rotary tillage operations. In this embodiment, the cleaning mechanism 2 includes a drive component 3 and a reciprocating component 4, and the reciprocating component 4 is linked and cooperates with the drive component 3. Specifically, the drive component 3 includes a drive motor 31 fixed to the upper surface of the leveling plate 13. The drive motor 31 is a dual-axis motor, and its two output shafts are respectively equipped with a rotating drum 32 and a synchronizing element 33. The rotating drum 32 has a guide groove 34 arranged spirally around its outer surface.

[0026] The reciprocating assembly 4 includes a reciprocating plate 41, a toothed plate 42 fixed to one side of the reciprocating plate 41, and a connector 43 disposed on one side of the reciprocating plate 41 and linked with the drive assembly 3. The reciprocating plate 41 is provided with a reciprocating shaft 45 for striking, and a connecting frame 46 is provided on the outside of the reciprocating shaft 45. A crossbar 47 is fixed on the outer wall of the connecting frame 46, and a guide wheel 48 is rotatably mounted at the end of the crossbar 47. The reciprocating plate 41 is provided with a guide groove 49 that rolls with the guide wheel 48. Through the rolling engagement of the ball bearing 433 with the guide groove 49, the rotational motion of the drive motor 31 is converted into the reciprocating linear motion of the reciprocating plate 41, which is the reciprocating striking action of the cleaning mechanism 2. In this embodiment, the reciprocating plate 41 is used in conjunction with the drive assembly 3 via a connector 43. The connector 43 includes an electric telescopic rod 431, a connecting rod 432 fixed to the output end of the electric telescopic rod 431, and a ball bearing 433 rotatably mounted on the end of the connecting rod 432 and rollingly engaging with the guide groove 34. The electric telescopic rod 431 is fixed to one side of the reciprocating plate 41. In use, the electric telescopic rod 431 in the connector 43 can adjust the position of the connecting rod 432 according to actual needs, thereby changing the position of the ball bearing 433 in the guide groove 34. This allows for flexible control of the reciprocating motion amplitude and frequency of the reciprocating plate 41, enabling the cleaning mechanism 2 to adapt to different working environments and debris cleaning needs, thus improving the cleaning effect.

[0027] To achieve reciprocating striking, a limit bracket 410 is bolted to the top side of the flat plate 13. A mounting sleeve 44, penetrating the interior of the limit bracket 410, is fixed to the outer surface of the reciprocating shaft 45. The end of the crossbar 47 away from the guide wheel 48 is fixed to the outer surface of the mounting sleeve 44. The guide groove 49 has a wavy shape. Specifically, an abutment block 411 is fixed to the bottom end of the reciprocating shaft 45, and a connecting ring 412 is sleeved on the outer surface of the bottom end of the reciprocating shaft 45. The connecting ring 412 and the abutment block 411 are fixed together. There are multiple reciprocating shafts 45, which are surrounded by a buffer spring 413 on the outer surface of the reciprocating shaft 45. The buffer spring 413, which is fixed between the connecting ring 412 sleeved on the outer surface of the bottom end of the reciprocating shaft 45 and the abutment block 411, can play a buffering role when the reciprocating shaft 45 strikes the flat plate 13, reduce the impact force on the flat plate 13, avoid damage to the flat plate 13 due to excessive striking, and at the same time reduce the vibration and noise of the cleaning mechanism 2 itself, and improve the stability and comfort of the equipment.

[0028] It should be noted that the force generated by reciprocating tapping can act on the soil surface at a certain frequency and intensity. During the smoothing process, continuous tapping can make the soil particles more compacted together, resulting in more uniform soil compaction compared to a single smoothing action. For example, in fields where crops are grown, uniformly compacted soil can provide a more stable growing environment for seeds, which is conducive to seed germination and root development. Since ordinary smoothing methods may leave some areas of loose soil, the reciprocating tapping function can target these localized loose areas. Through repeated tapping, the loose soil is made compacted again, ensuring consistent soil compaction throughout the work area and improving the overall quality of the land. In addition, after rotary tillage, some large clods may remain in the soil. The reciprocating force of the tilling can act like a small hammer, gradually breaking these large clods into smaller particles. Smaller soil particles improve soil aeration and water retention, creating favorable conditions for plant root growth. For example, in vegetable cultivation, good soil structure can promote root development and increase vegetable yield and quality.

[0029] Example 3, as Figure 5 , Figures 7 to 9 As shown, this is the third embodiment of the present invention, which differs from the second embodiment in that: the cleaning mechanism 2 further includes a liquid storage structure 5 and a liquid delivery component 6 that are linked with the reciprocating component 4, and a spraying component 7 that is connected to the drive component 3 and linked with the liquid delivery component 6 is provided above the flat plate 13. The synchronizing element 33 is provided between one of the output shafts of the drive motor 31 and the spraying component 7. The synchronizing element 33 includes two synchronizing pulleys of different sizes, and a synchronous belt is connected between the two synchronizing pulleys.

[0030] The liquid storage structure 5 includes a liquid storage tank 51 fixed to the top side of the flat plate 13, a stirring rod 52 rotatably installed inside the liquid storage tank 51, and a gear 53 fixed to the top of the stirring rod 52. The gear 53 meshes with the toothed plate 42. When the reciprocating plate 41 moves back and forth, the toothed plate 42 drives the gear 53 and the stirring rod 52 to rotate in both directions, thereby automatically stirring the liquid in the liquid storage tank 51, preventing sedimentation, and ensuring uniform liquid concentration and consistent spraying effect.

[0031] To provide a cleaning effect, the infusion assembly 6 includes a pressure cylinder 61 fixed to the upper surface of the smoothing plate 13, and two check valves 62 fixed to the outer wall of the pressure cylinder 61. Each check valve 62 has a connecting pipe 63 fixed to its end, which is connected to the storage tank 51 and the spraying assembly 7, respectively. A piston 64 extends outward from the pressure cylinder 61, and a buffer block 65 is fixed to the end of the piston 64, abutting against the outer wall of the reciprocating plate 41. A return spring 66 is installed between the buffer block 65 and the pressure cylinder 61. It should be noted that the infusion assembly 6 can not only be used in conjunction with the reciprocating assembly 4 to clean the smoothing plate 13, but also in conjunction with the reciprocating assembly 4 and the smoothing plate 13 for soil treatment, such as spraying pesticides with vibration.

[0032] To ensure the reciprocating stability of piston 64, pressure cylinder 61 is equipped with a lubricating component to protect piston 64. The lubricating component includes a lubricating pad 67 fixed to the outer wall of piston 64. An extension groove 69 is formed inside piston 64, and a limiting shaft 68 is fixed to the outer wall of lubricating pad 67, which telescopically engages with the extension groove 69. A return spring 610 connected to the end of the limiting shaft 68 is fixed to the inner wall of the extension groove 69. A fitting component 611 for squeezing lubricating pad 67 is provided on one side of pressure cylinder 61 relative to piston 64. It should be noted that a protective tube communicating with lubricating pad 67 is installed outside pressure cylinder 61. Lubricating fluid is supplied to lubricating pad 67 through the protective tube, and then the fitting component 611 squeezes lubricating pad 67, lubricating the piston 64 and pressure cylinder 61. This effectively reduces wear on piston 64 during reciprocating motion, extends the service life of the equipment, and reduces maintenance costs. Specifically, the mating part 611 consists of a stop block and an electric push rod. The electric push rod moves the stop block to a suitable position. When the piston 64 is working, it abuts against the stop block to squeeze the lubricating pad 67, squeezing out the lubricant. At the same time, the lubricating pad 67 reciprocates with the piston 64, thereby effectively lubricating and protecting the pressure cylinder 61 and the piston 64.

[0033] To further improve the cleaning effect, the spraying assembly 7 includes a tilting frame 71 hinged to the outer wall of the flat plate 13. The tilting frame 71 is L-shaped, and one end of the tilting frame 71 is connected to the synchronizing component 33. Several spray pipes 74 are fixed inside the tilting frame 71 by bolts, and a multi-port pipe 72 for connecting the spray pipes 74 is fixed outside the tilting frame 71. A connecting pipe 73 connected to the infusion assembly 6 is fixed at the end of the multi-port pipe 72. The connecting pipe 73 is a flexible hose, which facilitates the tilting adjustment of the tilting frame 71. It should be noted that the tilting frame 71 is connected to the synchronizing component 33 through a shaft, and then tilted and adjusted through one of the output shafts of the drive motor 31. The tilting frame 71 swings and sprays, achieving uniform coverage. The pumped liquid is sprayed out through the spray pipes 74 of the spraying assembly 7. At the same time, the tilting frame 71 is driven by the synchronizing component 33 to swing back and forth, thereby expanding the spray coverage area and making rinsing or application of medicine more uniform and effective.

[0034] Combined with appendix Figures 1-9 The working principle of the above embodiments is as follows: First, one output shaft of the drive motor 31 drives the rotating drum 32 to rotate. Since the ball bearings 433 are embedded in the guide groove 34, the rotation of the rotating drum 32 is converted into the horizontal reciprocating motion of the connecting rod 432 through the rolling cooperation of the spiral groove and the ball bearings 433. This causes the connecting rod 432 to drive the reciprocating plate 41 to perform horizontal reciprocating motion. When the reciprocating plate 41 moves horizontally, the wave-shaped guide groove 49 inside it moves relative to the guide wheel 48 fixed on the mounting sleeve 44. The resulting relative motion forces the mounting sleeve 44 and the reciprocating shaft 45 to make violent up-and-down reciprocating movements under the constraint of the limiting frame 410. At this time, the abutment block 411 at the bottom of the reciprocating shaft 45 periodically and at high frequency strikes the back of the smoothing plate 13, which can effectively shake off the adhering wet soil. When it is necessary to adjust the reciprocating amplitude of the reciprocating plate 41, the position of the reciprocating plate 41 is adjusted by extending and retracting the electric telescopic rod 431, thereby extending the reciprocating distance of the reciprocating plate 41. When the reciprocating distance of the reciprocating plate 41 is extended, it will drive the reciprocating depth of the reciprocating shaft 45 to increase, and at the same time, it will drive the infusion assembly 6 to work. During the horizontal movement of the reciprocating plate 41, it periodically squeezes the buffer block 65 of the infusion assembly 6, pushing the piston 64 into the pressure cylinder 61 and compressing the internal liquid. At this time, the check valve 62 near the spray assembly 7 opens to supply liquid to the spray pipe 74; the check valve 62 near the storage tank 51 closes. When the reciprocating plate 41 leaves the buffer block 65, the return spring 66 pushes the piston 64 to return to its original position, creating a negative pressure in the pressure cylinder 61. At this time, the check valve 62 near the storage tank 51 opens to draw in the liquid; the check valve 62 near the spray assembly 7 closes. This cycle continues, achieving continuous pumping. Combined with the rotation of the tilting frame 71, it washes the leveling plate 13, effectively cleaning the soil and other debris attached to the leveling plate 13, ensuring the normal operation of the leveling plate 13, and improving the flatness of the ground after rotary tillage.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
