Description

Technical Field

[0001] This utility model relates to the field of small agricultural machinery technology, and in particular to a multifunctional agricultural implement connection device. Background Technology

[0002] In modern agricultural production, the level of agricultural mechanization is constantly improving, and various agricultural implements play a vital role in all aspects of agricultural production. Different agricultural operations often require the use of agricultural implements with different functions, and these agricultural implements usually need to be matched and connected with specific power sources. Multifunctional agricultural implement connection devices are key equipment to achieve the compatibility of power equipment with various agricultural implements, enabling one power equipment to complete multiple agricultural operations, greatly improving the versatility and utilization rate of agricultural machinery. Some multi-functional agricultural implement connection devices transmit power to the implements via the output shaft, adapting to terrain undulations. The multi-machine combination device uses the main beam as a frame, with individual beams moving flexibly. Compression springs and tie rods compensate for differences in ground elevation with elastic force, ensuring the implements stay close to the ground. At the same time, the fixed structure ensures overall stability. The three-point suspension device is hinged to the tractor via a triangular structure. The hydraulic system drives the lifting rod to control the lifting and lowering of the implements, and the upper tie rod is adjusted to calibrate the working angle. The quick-attachment device uses a mechanical locking mechanism to quickly engage and complete the physical connection. The electro-hydraulic interface connects synchronously to realize power and signal transmission, meeting the needs of quick implement changing. Some multi-functional agricultural implement connecting devices have insufficient connection tightness, are easily loosened by bumps in complex terrain, have defects in angle adjustment, and have poor adaptability to different agricultural implements. Therefore, a multi-functional agricultural implement connecting device is proposed to solve the above problems. Utility Model Content

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] A multi-functional agricultural implement connection device, as described in the reference Figure 1 and Figure 2The system includes an agricultural machinery power source 1, a complete connection device, and external agricultural implements to provide the power required for operation. The power source 1 is externally slidably connected to a power source connection mechanism 2 for connecting to the power source 1. The power source connection mechanism 2 is externally rotatably connected to an agricultural implement connection mechanism 3 for connecting agricultural implements. The agricultural implement connection mechanism 3 is externally fixedly connected to an agricultural implement connection end 4, which is detachable to adapt to different agricultural implements. The power source connection mechanism 2 includes a flange connection assembly 22 for reinforcing the connection to prevent loosening due to vibration or load impact during operation. This is the core structure ensuring connection stability. The flange connection assembly 22 has an externally slidable connection end 4. The external spline shaft 21 ensures that the flange connection assembly 22 can be flexibly connected to the agricultural machinery power source 1. The external spline shaft 21 is externally fixed to the agricultural machinery power source 1. The external fixed connection of the flange connection assembly 22 is supported by a fixed plate a23 and a component mounting base. The external fixed connection of the fixed plate a23 is supported by a fixed block 24 and a component mounting base. The external fixed connection of the fixed block 24 is a rotating shaft 25 to ensure that the agricultural implement always maintains a suitable working angle with the ground, thereby improving the working quality. The external rotating connection of the rotating shaft 25 is internally connected to the agricultural implement connection mechanism 3 to transmit part of the traction force to the agricultural implement. Specifically, in this multi-functional agricultural implement connection device, the flange connection component 22 of the power source connection mechanism 2 slides with the external spline shaft 21, which can accurately transmit the torque of the agricultural machinery power source 1 and finely adjust the connection position to adapt to the power output end of different models of agricultural machinery. The flange connection component 22, together with the fixing plate a23 and the fixing block 24, greatly improves the rigidity of the connection structure, optimizes the connection loosening caused by vibration during agricultural machinery operation, reduces the risk of component wear, and extends the service life of the device. The rotating shaft 25 on the fixing block 24 is rotatably connected to the agricultural implement connection mechanism 3, so that the agricultural implement connection end 4 can be flexibly adjusted to adapt to the operation needs of complex terrains such as hills and slopes, without the need for frequent disassembly and replacement of the connection device. The fixing structure of the external spline shaft 21 and the agricultural machinery power source 1 ensures power transmission and improves the efficiency of agricultural machinery operation. The overall modular design of the components makes installation and disassembly convenient, and a single person can complete the switching of agricultural implements, reducing the preparation time for operation. It takes into account multi-functional adaptability and practicality to meet the needs of diverse agricultural machinery operation scenarios.

[0011] The flange connection assembly 22 includes an inner spline shaft 221. The spline structure enables efficient torque transmission, preventing agricultural machinery malfunctions due to power interruption during operation. The inner spline shaft 221 is externally slidably connected to multiple screw rods a222 for reinforcement. Multiple nuts a223 are externally threaded to the multiple screw rods a222 for reinforcement. Multiple nuts b224 are externally threaded to the multiple screw rods a222 to ensure tight contact of the connection surfaces and improve the overall rigidity of the flange connection assembly 22. The multiple screw rods a222 are externally slidably connected to a connecting block 225, which ensures connection stability through its multi-interface design. The inner spline shaft 221 is internally slidably connected to the outer spline shaft 21, and externally slidably connected to the connecting block 225 to achieve efficient torque transmission, preventing agricultural machinery malfunctions due to power interruption during operation. The connecting block 225 is externally fixedly connected to the outside of the fixing plate a23. Specifically, in the flange connection assembly 22, the inner spline shaft 221 and the outer spline shaft 21 slide together, and the spline structure fits tightly, which can reduce torque loss during power transmission and ensure that the power of the agricultural machinery power source 1 is efficiently transmitted to the agricultural implements. Especially in high-intensity operation scenarios such as deep plowing and heavy load, it can avoid the decrease in operation efficiency due to power loss. The spline sliding structure allows the inner spline shaft 221 to be finely adjusted along the outer spline shaft 21 to adapt to the power input requirements of different agricultural implements and improve the versatility of the device. Multiple lead screws a222, together with nuts a223 and b224, can double-connect the connection between the connecting block 225 and the inner spline shaft 221. The screw is securely fastened by the bidirectional locking of nuts a223 and b224 to prevent it from loosening due to severe vibration during agricultural machinery operation, thus avoiding gaps in the connection and reducing the risk of collision and wear on components. The connecting block 225 is fixedly connected to the fixing plate a23. The synergistic effect of the screw and the spline shaft makes the overall structure of the power source connection mechanism 2 more rigid, able to withstand the impact load during agricultural machinery operation, and extend the service life of the device. The threaded connection of the screw and nut facilitates disassembly and adjustment during later maintenance, allowing for component inspection or replacement without special tools, reducing agricultural machinery maintenance costs and time costs, and adapting to the needs of complex field operation environments.

[0012] Reference Figure 3 and Figure 4The agricultural implement connection mechanism 3 includes a lower hook block 31 that serves as a hook for connecting to the lower suspension arm of the agricultural implement. The hook structure enables quick mounting and dismounting of the implement. The lower hook block 31 has an internal threaded connection to a lead screw b32 to ensure the lower suspension point does not shift laterally during operation, guaranteeing balanced force on the implement. The lead screw b32 has two external threaded connections to prevent the lower hook block 31 from sliding along the lead screw due to vibration during operation. The lead screw b32 has an external threaded connection to a limit frame 34 to prevent axial movement of the lead screw during adjustment. The limit frame 34 has an external threaded connection to a lead screw c36 to ensure the lower suspension point does not shift laterally during operation. The lead screw c36 has an external threaded connection to... The upper hook block 35, with its hook-like structure, is connected by a threaded connection to enable quick mounting and dismounting of agricultural implements. The external threaded connection of the lead screw c36 has two nuts d37 to prevent the lower hook block 31 from sliding along the lead screw due to vibration during operation. The upper hook block 35 is externally fixedly connected to a fixing plate b38, which provides additional support for the upper hook block 35 and enhances its impact resistance. The external threaded connection of the fixing plate b38 is a lead screw d39, which can be detached to replace different agricultural implements. The external threaded connection of the lead screw d39 is a nut e3010 to enhance the connection's firmness. The external threaded connection of the lead screw d39 is a fixing plate c3011 to ensure the relative position stability between the agricultural implement connection end 4 and the suspension structure. Specifically, in this agricultural implement connecting mechanism 3, the lower hook block 31 and the upper hook block 35 cooperate to quickly hook the connecting structure of agricultural implements of different specifications. The lead screws b32 and c36 adjust the distance between the lower hook block 31 and the limiting frame 34, and the upper hook block 35 and the limiting frame 34, respectively, to adapt to the connecting ends 4 of agricultural implements of different thicknesses, from seeders to harvesters, thus optimizing the problem of the traditional connecting device having only one adaptability. Nuts c33 and d37 provide bidirectional locking to the adjusted lead screws to prevent the lead screws from loosening due to vibration during agricultural machinery operation, ensuring that the hook blocks and agricultural implements are tightly fitted and preventing the risk of falling off. Fixed plates b38 and c3011 are connected to nuts e3010 via screw d39, which can further strengthen the lateral connection between agricultural implements and connecting mechanisms, enhance overall impact resistance, and effectively distribute load and reduce wear on connecting parts during high-intensity operations such as tilling and soil breaking. Limiting frame 34 limits the adjustment range of screw d39 to avoid over-adjustment leading to component misalignment and ensure connection accuracy. The threaded connection structure of each screw d39 and nut does not require special tools for adjustment. During field operations, a single person can quickly complete the switching and tightening of agricultural implements, shortening the preparation time for operation.

[0013] The lower hook block 31 is internally rotatably connected to the outside of the power source connection mechanism 2 to adapt to the undulating terrain of the farmland and realize multi-angle adjustment of the agricultural implement. The lower hook block 31 is internally rotatably connected to the outside of the rotating shaft 25 to realize multi-angle adjustment of the agricultural implement. The lower hook block 31 is externally slidably connected to the outside of the upper hook block 35 through hook connection to ensure connection stability. The lower hook block 31 is externally slidably connected to the outside of the limit frame 34 to prevent the lead screw from axially moving during the adjustment process. The lead screw c36 is externally slidably connected to the outside of the limit frame 34 to prevent the lead screw from axially moving during the adjustment process. The fixed plate b38 is externally slidably connected to the outside of the fixed plate c3011 for easy disassembly and repair. The fixed plate c3011 is externally fixedly connected to the outside of the agricultural implement connection end 4 to ensure the stability of the connection with the agricultural implement. Specifically, in the agricultural implement connecting mechanism 3, the lower hook block 31 is rotatably connected to the rotating shaft 25, and its angle can be flexibly adjusted according to the power source connecting mechanism 2. To meet the operational needs of complex terrain, this ensures the agricultural implement remains in close contact with the ground, improving operational quality. The lower hook block 31 also slides in conjunction with the lead screw c36 and the limiting frame 34. Combined with the adjustment function of the lead screw c36, the relative position of the lower hook block 31 and the upper hook block 35 can be further fine-tuned. The sliding structure of the lead screw c36 and the limiting frame 34 provides stable guidance for the adjustment process, ensuring the hook block remains in contact with the agricultural implement connecting end 4. With a tight fit, the fixing plate b38 and the fixing plate c3011 are slidably connected, and the fitting distance can be flexibly adjusted according to the thickness of the agricultural implement connection end 4. Combined with the tightening effect of the screw d39 and the nut e3010, the double fixation significantly enhances the resistance to vibration and impact. In high-intensity operations such as deep plowing and soil pulverization, it can effectively reduce the detachment or displacement of agricultural implements. The fixing plate c3011 is directly fixed to the agricultural implement connection end 4, which shortens the force transmission path, reduces power loss, improves the efficiency of agricultural machinery operation, and takes into account the needs of adapting to complex scenarios and long-term reliable use.

[0014] The implementation principle of this application embodiment is as follows: when the power source of the agricultural implement is connected, the external spline shaft 21 is slidably connected in the flange connection assembly 22, and is reinforced by multiple screws a222 and nuts a223. Then, the cooperation of the fixing plate a23 and the fixing block 24 allows the agricultural implement to move at multiple angles.

[0015] When connecting to a multi-functional agricultural implement, the lower hook block 31 is connected to the power source connection mechanism 2. After the lower hook block 31 and the upper hook block 35 are hooked together, they are fixed by the limit frame 34 in conjunction with the lead screws b32 and c36. The fixing plate b38 and the fixing plate c3011 are connected to the nut e3010 through the lead screw d39. The connection end 4 can be detached to accommodate different types of agricultural implements and adapt to different agricultural implements.
