Description

Technical Field

[0001] The utility model relates to the technical field of agricultural straw baling equipment, in particular to a modular power connection device for agricultural machinery. Background Art

[0002] Corn stalks, one of the main waste materials in farmland, are crucial for improving agricultural resource utilization and protecting the environment. Currently, walking corn stalk balers are effective equipment for processing corn stalks, primarily used for shredding and baling farmland stalks. Existing shredding balers are often driven by a tractor and powered by the tractor's power output. Specifically, the tractor's power output shaft is connected to the input end of a transfer gearbox's drive shaft via a universal joint, and the transfer gearbox's power output is connected to the shredding baler. Due to the limitations of the universal joint connection, the transfer gearbox's drive shaft can only rotate horizontally within ±30° relative to the tractor's power output shaft. This significantly restricts the shredding baler's operation. When operating on small plots, at large angles, and within a small radius, the tractor's power output shaft must be stopped and the tractor's baler suspended to avoid damaging the universal joint drive shaft. This results in low tractor operating efficiency and significantly reduces the service life of the tractor's clutch.

[0003] The utility model patent with authorization announcement number CN210218566U discloses a universal input transfer device for a baler, including a transfer gearbox, a fixed gearbox, a rotating gearbox, and a connecting vertical shaft. The transfer gearbox is provided with three gears meshing in sequence, and has an input shaft end and two output shaft ends; the fixed gearbox and the rotating gearbox are connected in series on the connecting vertical shaft and are rotatably connected to the vertical shaft; a power input shaft is provided in the rotating gearbox, one end of the power input shaft extends out of the rotating gearbox housing, and the other end is provided with a first bevel gear; a second bevel gear and a third bevel gear are fixed on the connecting vertical shaft, the second bevel gear meshes with the first bevel gear, and a fourth bevel gear meshes with the third bevel gear; the fixed gearbox is fixedly connected to the housing of the transfer gearbox, and the input shaft end of the transfer gearbox extends into the fixed gearbox and is fixed to the fourth bevel gear. Its advantage is that it can achieve small radius steering without stopping when working on small plots of land, but one end of the transfer gearbox of the device is cantilevered, and the connection strength is poor, which reduces the service life of the device, is not conducive to local replacement and maintenance, and has high maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to provide a modular power connection device for agricultural machinery, which can adaptively adjust the angle of the output shaft relative to the input shaft, so that the connected traction equipment and working equipment can achieve small-angle turning.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0015] In this utility model, the rotating assembly enables the power input and output assemblies to rotate within a range of no less than 180°, allowing the tractor and baler to rotate relative to each other to the greatest extent possible, reducing the turning radius. The splitter assembly and support frame are connected to the power input and output assemblies at both ends, providing strong connection strength and enhancing the structural stability of the device. The overall modular design facilitates disassembly and installation, allowing for individual replacement and repair, reducing maintenance costs. The splitter assembly increases the number of output shafts, allowing for connection to multiple working components to be driven, thereby improving overall driving capacity.

The power input and output shafts typically extend through the first and second gearboxes, respectively. The third and fourth bevel gears can be interchanged to achieve reversal of the output shaft's rotational direction, making adjustment simple and convenient. The first and second gearboxes are symmetrically designed for interchangeable use, extending their service life. The number of teeth on the first and second spur gears in the transfer assembly can also be changed to adjust the output speed. BRIEF DESCRIPTION OF THE DRAWINGS
