Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to a tractor-driven tiller. Background Technology

[0002] In the field of landscaping, soil turning is a crucial and fundamental task that can effectively improve the physical structure of the soil, enhance its aeration and permeability, and create favorable conditions for plant growth.

[0003] Currently, hand-held tractor-trailers are commonly used for this type of work in landscaping. In practice, workers must hold the machine handles throughout the entire operation, relying on human guidance to control the direction and speed. Although the equipment itself provides digging power, reducing the user's physical exertion, the entire work process is limited by the operator's walking speed. Human walking speed is relatively slow, directly leading to low efficiency in soil turning. Utility Model Content

[0004] To address the problem of low operating efficiency caused by the reliance on manual walking towing of walk-behind soil turners, this application provides a towed soil turner.

[0005] The towed tillage machine provided in this application adopts the following technical solution: A towed tiller includes a rotary tillage assembly, a drive mechanism, a height adjustment assembly, and a traction connection assembly. The rotary tillage assembly includes a rotary tiller with a rotary tiller frame. The drive mechanism includes a drive motor mounted on the rotary tiller frame and used to drive the rotary tiller. The height adjustment assembly includes an adjustment support frame and a height adjustment component. The adjustment support frame is mounted on the rotary tiller frame and has support wheels. The height adjustment component is located between the adjustment support frame and the rotary tiller frame and is used to adjust the height of the rotary tiller above the ground. The traction connection assembly includes a traction support frame mounted on the rotary tiller frame and has a structure for connecting a traction vehicle.

[0006] By adopting the above technical solutions, the rotary tillage component realizes soil turning operations; the drive mechanism provides a continuous and stable power source for turning operations; the height adjustment component enables flexible adjustment of the rotary tiller's working height by adjusting the support frame and height adjustment components, allowing the tiller to adapt to different terrain conditions and tillage needs; the traction connection component establishes a reliable connection with the tractor through the traction support frame, enabling the tiller to utilize the tractor's traveling power, effectively overcoming the dependence of traditional hand-held tillers on the operator's walking speed, and significantly improving work efficiency.

[0007] Preferably, the drive motor has a drive pulley at its power output end, the rotary tiller has a transmission box, the transmission box has a drive shaft at its power input end, the drive shaft has a driven pulley at its end, and a belt is provided between the driven pulley and the drive pulley; the lower end of the transmission box has a rotary tillage shaft, which is the power output component of the transmission box, and the rotary tillage shaft has rotary tillage blades.

[0008] By adopting the above technical solution, the driving pulley and the driven pulley form a belt transmission system through the belt, realizing the smooth transmission of power; the transmission box reliably transmits power to the rotary tillage shaft, driving the rotary tillage blade to rotate and cut, completing efficient and uniform tillage operation.

[0009] Preferably, the drive mechanism further includes a tensioning support frame, on which a first tensioning pulley is provided; the first tensioning pulley is located on one side of the belt.

[0010] By adopting the above technical solution, the coordinated use of the tensioning support frame and the first tensioning pulley makes it easier to adjust the belt tension, which helps to maintain the stability of the belt drive process, reduce belt slippage, and ensure the reliability of power transmission.

[0011] Preferably, the drive mechanism further includes a clutch assembly, which includes an adjusting plate, a pulling elastic element, a clutch rod, and a clutch handle. The adjusting plate is rotatably mounted on the rotary tiller frame, and a second tension wheel is provided on the adjusting plate. The second tension wheel is located on one side of the belt. The pulling elastic element is disposed between the rotary tiller frame and the adjusting plate. The pulling elastic element is used to press the second tension wheel against the belt. The clutch handle is disposed on the rotary tiller frame, and the clutch rod is disposed between the adjusting plate and the clutch handle.

[0012] By adopting the above technical solution, the clutch assembly can control the tightening or loosening of the second tensioner pulley on the belt by operating the clutch handle, realizing convenient control of the connection and disconnection of power transmission, simplifying the operation process and improving the ease of use.

[0013] Preferably, the height adjustment component is an electric push rod.

[0014] By adopting the above technical solution, the height adjustment component uses an electric push rod as the drive source, which can provide a stable and controllable linear thrust, thereby realizing precise and smooth adjustment of the working height of the rotary tiller.

[0015] Preferably, the rotary tiller frame is also equipped with a battery, which is connected to an electric push rod via wires.

[0016] By adopting the above technical solution, the battery provides an independent power supply for the electric actuator, ensuring that the height adjustment component can obtain a stable and continuous power source under various working conditions, thus guaranteeing its normal operation.

[0017] Preferably, the drive unit is a diesel engine, the diesel engine is equipped with an igniter, and the battery is connected to the igniter via wires.

[0018] By adopting the above technical solution, the battery powers the diesel engine's igniter, ensuring that the drive engine can start quickly and reliably and maintain stable operation.

[0019] Preferably, the traction connection assembly includes a traction telescopic rod, which is slidably mounted on a traction support frame. A buffer elastic element is also sleeved on the traction telescopic rod, with one end of the buffer elastic element abutting against the traction telescopic rod and the other end of the buffer elastic element abutting against the traction support frame. The traction telescopic rod is used to connect to the tractor vehicle.

[0020] By adopting the above technical solution, the combined design of the traction telescopic rod and the buffer elastic component can effectively buffer and absorb the vibration and impact load generated during the movement of the tractor, reduce the transmission of these adverse factors to the tiller body, thereby improving the overall working stability and extending the service life of key components.

[0021] In summary, this application includes the following beneficial technical effects: By incorporating a traction connection assembly, the tiller is reliably connected to the tractor unit via a traction support frame and a traction telescopic rod. This allows the tiller's propulsion to be entirely provided by the tractor unit, eliminating reliance on the operator's walking speed and significantly improving tillage efficiency. The drive mechanism provides ample tillage power to the rotary tillage unit via a drive motor; the height adjustment assembly, driven by an electric push rod, adjusts the support frame to flexibly adjust the tillage depth to adapt to different agronomic requirements; the clutch assembly simplifies the engagement and disengagement of power; and the buffer elastic element in the traction connection assembly effectively dampens the impact and vibration from the tractor unit. In summary, this traction tiller effectively solves the problem of low operating efficiency in traditional equipment, offering advantages such as high practicality, ease of operation, and high work efficiency.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] This application discloses a tractor-driven tiller, with reference to... Figure 1 The device includes a rotary tillage assembly 1, a drive mechanism 2, a height adjustment assembly 3, and a traction connection assembly 4. The rotary tillage assembly 1 includes a rotary tiller 11, which is used for tilling the soil. The drive mechanism 2 is used to drive the rotary tiller 11. The height adjustment assembly 3 is used to adjust the height between the rotary tiller 11 and the ground. The traction connection assembly 4 is used to detachably connect the towed tiller to a tractor vehicle. In this embodiment, the tractor vehicle is an ATV.

[0031] Reference Figures 1-2A rotary tiller frame 111 is fixedly connected to the rotary tiller 11, and a transmission box 112 is also vertically fixedly connected to the rotary tiller 11. In this embodiment, the transmission box 112 is a sprocket transmission box. A drive shaft 1121 is rotatably connected to the upper end of the transmission box 112, which is the power input component of the transmission box 112. A driven pulley 11211 is fixedly connected to one end of the drive shaft 1121. A rotary tillage shaft 113 is rotatably connected to the lower end of the transmission box 112, and the rotary tillage shaft 113 is the power output component of the transmission box 112. A rotary tillage blade 1131 is fixedly connected to the rotary tillage shaft 113. The transmission box 112 is used to transmit the power of the drive mechanism 2 to the rotary tillage shaft 113. The transmission sprocket box is prior art and will not be described in detail here.

[0032] Reference Figures 1-3 The drive mechanism 2 includes a drive motor 21, a belt 22, a tensioning support frame 23, and a clutch assembly 24. In this embodiment, the drive motor 21 is a diesel engine. The drive motor 21 is fixedly connected to the upper end of the rotary tiller frame 111. A drive pulley 211 is fixedly connected to the end of the output shaft of the drive motor 21. The belt 22 is sleeved on the drive pulley 211 and the driven pulley 11211. In this embodiment, the tensioning support frame 23 is an L-shaped frame. Two waist-shaped grooves 231 are formed on the vertical section of the tensioning support frame 23. A first tensioning wheel 232 is rotatably connected to the end of the horizontal section of the tensioning support frame 23. The first tensioning wheel 232 is located at the lower end of the belt 22. Reference Figures 1-3 The tensioning support frame 23 is positioned on the drive motor 21 by fasteners passing through a waist-shaped groove 231 on the vertical section. The waist-shaped groove 231 extends vertically, allowing the tensioning support frame 23 to be adjusted vertically relative to the drive motor 21. When adjusting the tension of the belt 22, the fasteners are first loosened, and then the tensioning support frame 23 is moved up or down along the waist-shaped groove 231. When moving upward, the first tensioning wheel 232 at the end of the tensioning support frame 23 applies tension to the belt 22, tightening it; when moving downward, the tension on the belt 22 is correspondingly reduced, slackening it. After adjusting to the desired position, the fasteners are retightened to secure the tensioning support frame 23 to the drive motor 21.

[0033] Reference Figures 1-3The clutch assembly 24 includes an adjusting plate 241, a pulling elastic element 242, a clutch rod 243, and a clutch handle 244. A bracket is fixedly connected to the upper end of the transmission box 112. One end of the adjusting plate 241 is rotatably connected to the bracket, and the other end of the adjusting plate 241 is rotatably connected to a second tension wheel 2411. A row of mounting holes 2412 is also provided on the adjusting plate 241. The pulling elastic element 242 is vertically arranged and is a tension spring. The upper end of the tension spring is attached to the mounting holes 2412, and the lower end of the tension spring is attached to the rotary tiller frame 111. The second tension wheel 2411 is located at the upper end of the belt 22. Under the action of the tension spring, the second tension wheel 2411 is always pressed tightly against the upper end of the belt 22. A clutch support frame 1111 is vertically fixed to the end of the rotary tiller frame 111 furthest from the drive motor 21. A clutch handle 244 is rotatably connected to the clutch support frame 1111. One end of a clutch lever 243 is rotatably connected to an adjusting plate 241, and the other end is rotatably connected to the clutch handle 244. The rotatable connection point between the clutch handle 244 and the clutch support frame 1111 is closer to the drive motor 21 than the rotatable connection point between the clutch lever 243 and the clutch handle 244. When the clutch handle 244 is pulled upwards, it causes the adjusting plate 241 to deflect downwards via the clutch lever 243, thereby pressing down the upper end of the belt 22 on the second tension pulley 2411. At this time, the friction between the belt 22 and the drive pulley 211 and the driven pulley 11211 increases, allowing the drive pulley 211 to drive the driven pulley 11211 to rotate via the belt 22, thus transmitting power. Conversely, when the clutch lever 244 is pulled downwards, the clutch lever 244 drives the adjusting plate 241 to deflect upwards via the clutch rod 243, thereby causing the second tension pulley 2411 to disengage from the upper end of the belt 22. At this time, the friction between the belt 22 and the drive pulley 211 and the driven pulley 11211 decreases, becoming insufficient to cause the drive pulley 211 to drive the driven pulley 11211 to rotate via the belt 22, thus interrupting power transmission. In this manner, the clutch assembly 24 achieves control over the power transmission of the drive mechanism 2.

[0034] Reference Figures 1-3In this embodiment, the upper end of the clutch support frame 1111 is machined with an upwardly inclined ramp structure. One end of the clutch lever 243 is rotatably connected to the clutch handle 244 via a mounting bolt 2441. After assembly, the end of the mounting bolt 2441 is located directly above the ramp. When the clutch handle 244 is pulled downward, it rotates around its hinge point with the clutch support frame 1111, thereby pulling the adjusting plate 241 through the clutch lever 243, causing the adjusting plate 241 to deflect upward around the fulcrum on the bracket. This action overcomes the tension of the tension spring, causing the second tension wheel 2411 to lift off the belt 22, and the power transmission is cut off. In this disengaged state, the downward tension of the tension spring acts sequentially on the second tension wheel 2411, the adjusting plate 241, and the clutch lever 243, and is finally transmitted to the mounting bolt 2441 on the clutch handle 244. This tension attempts to drive the clutch handle 244 to continue rotating downward. However, since the connection point between the clutch lever 243 and the clutch handle 244 is now spatially lower than the hinge center between the clutch handle 244 and the clutch support frame 1111, the tension of the spring actually generates a downward torque on the clutch handle 244. Simultaneously, the end of the mounting bolt 2441 is tightly abutting against the ramp surface of the clutch support frame 1111. This contact point effectively prevents further rotation of the clutch handle 244. The torque generated by the tension of the spring balances the reaction force of the mounting bolt 2441 on the ramp, forming a stable force lock. This mechanism allows the clutch handle 244 to remain stably in the disengaged position without continuous external force, thus achieving reliable self-locking.

[0035] Reference Figure 1 and Figure 4 The height adjustment assembly 3 includes an adjustment support frame 31, a height adjustment element 32, a drive rod 33, and an actuator rod 34. The adjustment support frame 31 is vertically mounted on the rotary tiller frame 111, with its upper end rotatably connected to the rotary tiller frame 111 and its lower end rotatably connected to a support wheel 311. The drive rod 33 is vertically mounted on the rotary tiller frame 111, located on one side of the adjustment support frame 31, and its middle portion rotatably connected to the rotary tiller frame 111. In this embodiment, the height adjustment element 32 is an electric push rod, with its end rotatably connected to the rotary tiller frame 111 and its piston rod end rotatably connected to the upper end of the drive rod 33. One end of the actuator rod 34 is rotatably connected to the lower end of the drive rod 33, and the other end of the actuator rod 34 is rotatably connected to the lower end of the adjustment support frame 31.

[0036] Reference Figure 1 and Figure 4During operation, when the height of the rotary tiller 11 needs to be adjusted, the electric push rod is activated, driving its piston rod to extend and retract. The extension and retraction of the piston rod causes the drive rod 33 to rotate around its central pivot point. The rotation of the drive rod 33 further pushes the actuator rod 34, which converts the rotational motion of the drive rod 33 into the oscillation of the adjusting support frame 31. Specifically, when the piston rod of the electric push rod extends, the upper end of the drive rod 33 is pushed forward, and the drive rod 33 rotates around its central pivot point, while its lower end moves backward. This pulls the lower end of the adjusting support frame 31 through the actuator rod 34, causing the adjusting support frame 31 to deflect forward around its upper pivot point, thereby reducing the gap between the rotary tiller 11 and the ground. Conversely, when the piston rod of the electric push rod retracts, the upper end of the drive rod 33 is pulled back, causing the drive rod 33 to rotate in the opposite direction. Its lower end moves forward, pushing the lower end of the adjusting support frame 31 through the actuator 34, causing the adjusting support frame 31 to deflect backward, thereby increasing the gap between the rotary tiller 11 and the ground. By controlling the stroke of the electric push rod, the working height of the rotary tiller 11 can be adjusted to adapt to different tillage needs.

[0037] Reference Figures 4-5 A baffle 12 is vertically installed on the side wall of the rotary tiller frame 111 near the adjusting support frame 31. The upper end of the baffle 12 is rotatably connected to the rotary tiller frame 111. A chain 13 is installed between the baffle 12 and the rotary tiller frame 111. One end of the chain 13 is fixedly connected to the lower end of the baffle 12, and the other end of the chain 13 is positioned by a locating pin installed on the rotary tiller frame 111. When the working height of the rotary tiller 11 relative to the ground changes, the deflection angle between the baffle 12 and the rotary tiller frame 111 needs to be adjusted accordingly. This adjustment is achieved by changing the effective connection length of the chain 13 on the rotary tiller frame 111. Specifically, the locating pin is pulled out from the current connecting ring of the chain 13, another connecting ring on the chain 13 is selected according to the required deflection angle, and then the locating pin is inserted into the selected connecting ring and fixed to the rotary tiller frame 111, thereby maintaining the baffle 12 at the adjusted deflection angle.

[0038] Reference Figure 1 and Figure 6The rotary tiller frame 111 is vertically fixed to a support sleeve 14 at the end furthest from the adjusting support frame 31. The traction connection assembly 4 includes a traction support frame 41 and a traction telescopic rod 42. The traction support frame 41 consists of a sliding adjusting sleeve 411 and a traction support tube 412. The sliding adjusting sleeve 411 is vertically slidably connected to the support sleeve 14, and the traction support tube 412 is fixedly connected to the lower end of the sliding adjusting sleeve 411, and the traction support tube 412 is perpendicular to the support sleeve 14. A positioning bracket is fixedly connected to the upper end of the traction support tube 412, and a spring pin 4122 is slidably connected to the positioning bracket. The sliding adjusting sleeve 411 has a sliding hole, and the support sleeve 14 has a row of positioning holes 141 along its length.

[0039] Reference Figure 1 and Figure 6 The traction telescopic rod 42 is slidably connected to the end of the traction support tube 412 away from the rotary tiller frame 111. A limit plate 4121 is fixedly connected inside the traction support tube 412. A buffer rod 421 is fixedly connected to the end of the traction telescopic rod 42 near the traction support tube 412. The end of the buffer rod 421 passes through the limit plate 4121, and a limit block 4212 is also fixedly connected to the end of the buffer rod 421. A buffer elastic element 4211 is sleeved on the buffer rod 421. In this embodiment, the buffer elastic element 4211 is a buffer spring. One end of the buffer spring abuts against the limit plate 4121, and the other end of the buffer spring abuts against the traction telescopic rod 42. The end of the traction telescopic rod 42 away from the rotary tiller frame 111 is hooked onto the tractor.

[0040] Reference Figure 1 and Figure 6 The overall height of the traction support frame 41 can be adjusted by the vertical sliding of the sliding adjustment sleeve 411 on the support sleeve frame 14, thereby adapting to the connection requirements of tractors of different heights. When the sliding adjustment sleeve 411 moves to the required height, the spring pin 4122 slides on the positioning bracket and inserts into the corresponding positioning hole 141 on the support sleeve frame 14, thereby fixing the sliding adjustment sleeve 411 and ensuring the stability of the traction support frame 41 during operation. During operation, when the tractor is traveling, the traction telescopic rod 42 is connected to the tractor through the attachment point at its end. Due to uneven ground or changes in working resistance, the tractor may experience vibration or impact. At this time, the traction telescopic rod 42 slides inside the traction support tube 412, and the buffer rod 421 moves accordingly, compressing or releasing the buffer spring. The elastic deformation of the buffer spring absorbs the impact energy, reducing the vibration transmitted to the rotary tiller 11, thereby protecting the rotary tillage assembly 1 and the drive mechanism 2, and improving the overall working stability and service life of the machine. The limit block 4212 is used to limit the movement range of the buffer rod 421, prevent the traction telescopic rod 42 from over-extending, and ensure a safe and reliable connection.

[0041] Reference Figure 1 and Figure 4 A battery 15 is also fixedly connected to the rotary tiller frame 111, and the battery 15 is connected to the electric push rod via wires. In this embodiment, the drive motor 21 is a diesel engine, and the diesel engine is equipped with an igniter. The battery 15 is connected to the igniter via wires.

[0042] The implementation principle of a tractor-driven tiller according to an embodiment of this application is as follows: When the tiller is working, it is connected to a tractor unit via a traction connection assembly 4, and the tractor unit provides the power for movement, thereby eliminating the limitation of relying on the operator's walking speed and improving the efficiency of tilling operations. Specifically, the tractor unit pulls the tiller to move, and the rotary tillage assembly 1 performs tilling operations under the drive mechanism 2. The drive mechanism 2 controls the power transmission through a clutch assembly 24, and the operator can easily connect and disconnect the power by operating the clutch handle 244. The height adjustment assembly 3 drives the drive rod 33 and the actuator rod 34 through an electric push rod, causing the adjustment support frame 31 to swing, thereby adjusting the height of the rotary tiller 11 above the ground to adapt to different tillage needs. The baffle 12 adjusts the deflection angle through a chain 13 and a positioning pin to ensure effective coverage at different working heights. In the traction connection assembly 4, the sliding adjustment sleeve 411 slides on the support sleeve 14 to adjust the overall height, and is fixed by inserting a spring pin 4122 into the positioning hole 141; the traction telescopic rod 42 absorbs the vibration and impact of the tractor during travel through a buffer spring. The battery 15 provides power to the electric push rod and the igniter of the drive motor 21.

[0043] 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.
