Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to a clutch split device for a rotary tiller. Background Technology

[0002] Rotary tillers, as indispensable agricultural machinery, are widely used in farming operations on various terrains such as plains and hills due to their excellent soil-breaking ability and the smoothness of the tilled ground. They are key equipment for improving agricultural efficiency and reducing the labor intensity of farmers. With the diversification of agricultural planting patterns, farmers' demands for the multi-functional adaptability of rotary tillers are increasing. They not only require them to complete basic rotary tillage operations, but also expect them to be able to perform composite operations such as ridging, hole digging, and multi-width tillage through equipment expansion, so as to adapt to the operational needs of different crops and different plot conditions.

[0003] As the core component of the rotary tiller's transmission system, the clutch plays a crucial role in power transmission and disconnection. Its structural design directly affects the rotary tiller's operational stability and flexibility. Existing rotary tillers generally adopt a single-shaft linkage transmission structure. The corresponding clutch split device is usually equipped with only one power output shaft. This shaft is directly connected to the working end and drives it to rotate. The shaft at the other end of the split device only serves as an auxiliary support structure and does not have power output or adjustment capabilities.

[0004] This traditional structure has significant limitations in practical applications: On the one hand, limited by the single-axis power output mode, the rotary tiller can only be equipped with one set of rotary tillage equipment, resulting in a single operating function that is difficult to meet diverse tillage needs; when different types of tillage operations need to be completed or adapted to plots of different widths and terrains, farmers need to replace different rotary tiller equipment or make complex modifications to existing equipment, which not only increases the cost of equipment purchase and maintenance but also seriously reduces tillage efficiency; on the other hand, the lack of adjustment capability of the support shaft makes it impossible for the rotary tiller to adjust operating parameters according to actual working conditions such as soil hardness and crop planting spacing during operation, which can easily lead to problems such as uneven tillage depth, missed tillage, or over-tillage, affecting the quality of tillage.

[0005] To address this issue, a clutch split device for rotary tillers is proposed to solve the problems existing in the prior art. Summary of the Invention

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the invention, and these aspects of the invention can be achieved even without these specific details.

[0018] Please see Figures 1 to 4 This invention provides a clutch split device for rotary tillers, the technical solution of which is as follows: The rotary tiller body includes a frame assembly, a drive unit, a transmission shaft assembly, a gearbox 2, and a rotary tiller. The drive unit is mounted on the frame assembly and is connected to the rotary tiller via the transmission shaft assembly, the gearbox 2, and the rotary tiller, driving the rotary tiller to rotate. The gearbox 2 is equipped with an adjustment box 7, and the adjustment box 7 contains an adjustment component for adjusting the rotary tiller.

[0019] The drive shaft assembly includes a first connecting bushing 3, a second connecting bushing 4, a first transmission box 5, and a second transmission box 6. Two rotary tillers are symmetrically arranged on the frame assembly. The frame assembly includes a pulley shaft 1, which is connected to the drive unit via a belt. The pulley shaft 1 is connected to a gearbox 2. The gearbox 2 is equipped with an adjustment box 7, and two first connecting bushings 3 are symmetrically arranged at its left and right ends. A transmission box 5 is located at the other end of each first connecting bushing 3. A second connecting bushing 4 is located at the other end of each first transmission box 5, and a second transmission box 6 is located at the other end of each second connecting bushing 4. A support plate 8 is provided on the side away from the gearbox 2, and the support plate 8 is L-shaped. Two support shafts 9 are symmetrically provided on the left and right sides of the support plate 8, and each support shaft 9 is connected to the corresponding transmission box 5. A support rod 10 is provided on the support plate 8, and the support rod 10 is arranged parallel to the two transmission boxes 6 and located in the middle of the two transmission boxes 6. A first rotary tillage shaft 11 and a second rotary tillage shaft 12 are symmetrically provided on the left and right sides of the other end of the support rod 10, and the other ends of the first rotary tillage shaft 11 and the second rotary tillage shaft 12 are connected to the corresponding transmission box 6. Multiple tillage plates 13 are provided on the first rotary tillage shaft 11 and the second rotary tillage shaft 12.

[0020] Rotary tillers are generally mounted on agricultural vehicles. The drive unit is the engine of the agricultural vehicle. The driving force is transmitted through belts to the first rotary tiller shaft 11 and the second rotary tiller shaft 12 via the pulley shaft 1, the drive shaft assembly and the frame assembly, so that the two rotary tiller shafts rotate and drive multiple tillage plates 13 to perform soil breaking / ridging operations. By adjusting the box 7 and adjusting the components, the rotary tiller can be equipped with two sets of rotary tillage equipment at the same time, namely the first rotary tillage shaft 11 and the second rotary tillage shaft 12. This breaks through the functional limitations of traditional single-shaft rotary tillers, enabling multi-width synchronous tillage and adapting to composite operation scenarios of main tillage + auxiliary soil crushing / ridging, greatly improving the operational function coverage of the rotary tiller. The regulating box 7 can independently control the rotation / disengagement state of the second rotary tiller 12: in soft soil, only single-axis operation can be used to reduce energy consumption, while in hard soil, dual-axis operation can be used to enhance tillage depth; at the same time, the dual-axis operation mode can be flexibly adjusted according to actual needs such as crop row spacing and plot width, effectively avoiding problems such as missed tillage and over-tillage, and improving the accuracy of tillage quality; moreover, there is no need to purchase multiple rotary tillers, one device can realize single / dual-axis operation switching, reducing farmers' equipment investment costs; at the same time, the flexible operation mode of dual rotary tillers can adapt to different plot conditions, reduce the number of back-and-forth tillage, avoid the repeated modification and time consumption of traditional single-axis equipment, and significantly improve tillage efficiency.

[0021] The adjustment assembly includes a drive shaft 14 horizontally disposed within the adjustment box 7, a drive shaft 15 sleeved on the drive shaft 14, and the drive shaft 14 and drive shaft 15 respectively passing through a connecting sleeve 3 on their respective sides and connected to the transmission box 5. The drive shaft 14 is provided with a drive gear 16, which cooperates with the gearbox 2. The drive shaft 15 is provided with a sliding sleeve 17, a driven gear 18 on the side of the sliding sleeve 17 away from the drive gear 16, and a linkage gear 19 on the other side of the sliding sleeve 17. The drive gear 16 is provided with a linkage groove 20 on the side near the sliding sleeve 17, and the shape of the linkage groove 20 is consistent with that of the linkage gear 19. The adjustment box 7 is provided with an adjustment mechanism for adjusting the connection relationship between the drive shaft 14 and the drive shaft 15.

[0022] Through the matching structure of the linkage groove 20 of the drive gear 16 and the linkage gear 19, and with the displacement adjustment of the sliding sleeve 17, the linkage / disengagement state of the first drive shaft 14 and the second drive shaft 15 can be precisely controlled. This ensures stable power transmission during dual-shaft linkage and also enables the independent disengagement of the second rotary tillage shaft 12, meeting the power output requirements under different working conditions. At the same time, the first drive shaft 14 and the second drive shaft 15 adopt a nested design. Combined with the modular layout of the sliding sleeve 17 and the driven gear 18, the dual-shaft transmission adjustment is integrated within the adjustment box 7. This reduces the space occupied by components and improves the operational stability of the transmission system and reduces the risk of failure through the rigid cooperation of gears and sleeves.

[0023] The adjustment mechanism includes a mounting base 21 set on the top of the adjustment box 7. The mounting base 21 is provided with a rotating shaft 22, which extends downward into the adjustment box 7. The lower end of the rotating shaft 22 is provided with an adjustment gear 23. The sliding sleeve 17 is provided with an adjustment ring groove 24. The adjustment ring groove 24 is provided with a push retaining ring 25, and the push retaining ring 25 is provided with an upwardly extending vertical rod 26. The top end of the vertical rod 26 is provided with an adjustment rack 27, and the adjustment rack 27 meshes with the adjustment gear 23.

[0024] The rotating shaft 22 drives the adjusting gear 23 to rotate, which in turn drives the adjusting rack 27 that meshes with it, thereby pushing the vertical rod 26 and the retaining ring 25 to achieve a smooth displacement of the sliding sleeve 17. This gear and rack meshing transmission method can precisely control the stroke of the sliding sleeve 17, ensuring the precise engagement or disengagement of the linkage gear 19 and the linkage groove 20, avoiding the jamming and misalignment of traditional adjustment methods, and improving the reliability of dual-axis state switching. It can be switched manually with tools, or an adjusting motor can be installed on the top of the adjusting box 7 for electric control of rotation switching. The mounting base 21, rotating shaft 22, adjusting gear 23 and other components are integrated on the top of the adjusting box 7 to form a compact modular structure. This structure does not occupy additional lateral space and ensures stable transmission of adjusting force through the rigid meshing of gears and racks. The design of the push ring 25 and the adjusting ring groove 24 makes the force on the sliding sleeve 17 more uniform, reduces wear during transmission, and improves the service life of the mechanism.

[0025] The upper part of the regulating box 7 is provided with a guide rod 28, the guide rod 28 is provided with a guide cylinder 29, and the outer circumference of the guide cylinder 29 is provided with a connecting rod 30. The other end of the connecting rod 30 extends downward and connects to the bottom of the vertical rod 26. A reinforcing rod 31 is provided between the vertical rod 26 and the connecting rod 30.

[0026] The sliding fit structure of the guide rod 28 and the guide cylinder 29 provides precise guiding constraints for the lifting and lowering displacement of the vertical rod 26, effectively limiting the deviation and swaying of the vertical rod 26 during movement. This ensures that the vertical rod 26 drives the push ring 25 and the sliding sleeve 17 to move smoothly in a straight line, thereby ensuring the precise meshing or disengagement of the linkage gear 19 and the linkage groove 20, and improving the reliability of the dual-shaft transmission state switching. The connecting rod 30 adopts a downward inclined connection method, which, together with the triangular support structure of the reinforcing rod 31, forms a stable mechanical support system. This effectively disperses the thrust and tension borne by the vertical rod 26 during adjustment, avoiding component deformation or breakage caused by local stress concentration. At the same time, the combined design of the inclined connecting rod 30 and the reinforcing rod 31 strengthens the connection strength between the vertical rod 26 and the guide cylinder 29, improving the overall load-bearing capacity and service life of the adjustment mechanism.

[0027] The drive shaft 15 has multiple limiting grooves 32 on its outer circumference near the driven gear 18, and the multiple limiting grooves 32 are evenly arranged in a circle. The driven gear 18 has multiple limiting blocks 33 evenly arranged in a circle on its inner ring away from the linkage gear 19, and the multiple limiting blocks 33 cooperate with the multiple limiting grooves 32.

[0028] The limiting block 33 on the inner ring of the driven gear 18 precisely engages with the limiting groove 32 on the outer circumference of the transmission shaft 15, forming a circumferential limiting structure. This effectively prevents relative rotation between the driven gear 18 and the transmission shaft 15, ensuring efficient and slip-free power transmission between them. During dual-shaft linkage operation, it ensures that the transmission shaft 15 rotates synchronously with the transmission shaft 14, avoiding fluctuations in the rotary tillage shaft speed caused by transmission slippage, thus improving the stability and tillage quality of rotary tillage operations. The matching structure of the limiting groove 32 and the limiting block 33 not only enables the driven gear 18 to slide smoothly along the axial direction of the transmission shaft 15, but also does not affect the circumferential power transmission, adapting to the requirement of the sliding sleeve 17 driving the driven gear 18 to shift and switch the dual-shaft connection state.

[0029] The multiple tillage plates 13 on the first rotary tillage shaft 11 and the second rotary tillage shaft 12 are evenly arranged along the axial direction, and the multiple tillage plates 13 are arranged in a staggered manner laterally; the multiple tillage plates 13 are provided with multiple rotating support rods 34, and the multiple rotating support rods 34 are arranged in a staggered manner around the circumference.

[0030] The tillage plates 13 are evenly arranged along the axis of the rotary tillage shaft and are staggered laterally, which can cut and break the soil within the width of the rotary tillage operation without dead angles, avoiding problems such as missed tillage and uneven tillage depth that are easy to occur when the tillage plates 13 are arranged in the same direction in the traditional way. At the same time, the staggered layout can disperse the impact force of the soil on the tillage plates 13, reduce equipment vibration during operation, and improve tillage stability. The circumferentially staggered rotating struts 34, in conjunction with the cutting action of the tillage plate 13, can further break up the soil clods turned up by the tillage plate 13, further refining soil particles, improving the flatness of the soil after tillage, and meeting the agronomic requirements of intensive farming. In addition, the rotating struts 34 can stir up weeds and straw in the field during operation, effectively preventing weeds from getting tangled on the rotary tiller shaft, reducing the frequency of downtime for cleaning, and ensuring continuous operation. Furthermore, when the rotary tiller is working, the blades will bear huge and uneven impact and torsional forces from the soil. The rotating struts 34 connect multiple independent blades into a whole frame, which greatly enhances the rigidity of the blade shaft assembly. At the same time, it can effectively prevent individual blades from excessively bending, twisting, or breaking when encountering hard objects such as stones and tree roots, thus improving the service life of the tillage plate 13 and the rotary tiller shaft.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
