Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a forward and reverse driving device for agricultural machinery. Background Art

[0002] In the process of modern agricultural mechanization, agricultural machinery is a key equipment for improving agricultural production efficiency. The optimization of its performance and functions is of great significance to promoting the sustainable development of agriculture. Traditional agricultural machinery drive devices often adopt a single drive mode, which makes it difficult to achieve flexible switching of drive direction and precise adjustment of speed. This greatly limits the adaptability and efficiency of agricultural machinery in complex operating environments. Especially in the process of arable land sowing, fertilization and other operations, different soil conditions, crop types and growth stages often require agricultural machinery to have different drive speeds and direction control capabilities to adapt to changing operational needs.

[0003] Most agricultural machinery drive devices in the existing technology achieve speed and direction adjustment through mechanical shifting or hydraulic transmission systems, but these methods have problems such as complex operation, slow response speed, and high maintenance cost. Especially in operating scenarios that require frequent switching of forward and reverse rotation or adjustment of speed, traditional methods not only increase the difficulty of operation, but may also reduce overall operating efficiency due to shutdown adjustments, affecting agricultural production progress. Therefore, in response to the above technical problems, a forward and reverse drive device for agricultural machinery is proposed herein. Utility Model Content

[0004] The purpose of the utility model is to provide a forward and reverse drive device for agricultural machinery, which can realize fast forward and reverse switching under different operating conditions, and can realize the adjustment of different speeds, thereby improving the operating flexibility of agricultural machinery, being applicable to various types of agricultural machinery, having broad application prospects, and reducing downtime during operation through fast switching of forward and reverse, thereby improving overall operating efficiency.

The precise meshing relationship between the gears enables precise control of power transmission. A second intermediate gear is introduced into the mechanism. Its engagement with the front gear directly drives the output gear and the rotating rod, completing the external output operation. To achieve flexible adjustment of the output speed, an adjustable gear set consisting of a first, second, and third intermediate gears is provided.

In addition, a control panel allows the operator to easily control the rotation direction of the drive motor through electronic commands, enabling rapid switching between forward and reverse rotation. This function is particularly critical for frequent changes in working direction or emergency adjustments, effectively reducing downtime during operation and significantly improving overall operational efficiency.

[0031] The speed regulating mechanism includes a lifting rod 9, a first intermediate gear 12, a second intermediate gear 13 and a third intermediate gear 14.

If the agricultural machinery is performing operations such as plowing, sowing, and fertilizing, when the rotation speed of the rotating rod 15 needs to be adjusted, the electric telescopic rod 6 can be operated to control the connecting rod 7 to move up and down, so that the connecting seat 8 drives the lifting rod 9 to adjust the first The intermediate gear 12 or the third intermediate gear 14 moves to the original position of the second intermediate gear 13 to complete the engagement with the front end gear 5. Since the inner diameters and tooth pitches of the first intermediate gear 12, the second intermediate gear 13 and the third intermediate gear 14 are different, the speed of the output gear 17 can be adjusted, which is easy to operate and conducive to rapid adjustment and switching. The rotation direction of the drive motor 3 can be adjusted arbitrarily through the control panel 19. In summary, the device can achieve rapid forward and reverse switching under different operating conditions, and can achieve adjustment of different speeds, thereby improving the operating flexibility of agricultural machinery. It can be applied to various types of agricultural machinery and has broad application prospects. Through rapid switching of forward and reverse, it reduces downtime during operation and improves overall operating efficiency.
