Description

Technical Field

[0001] The utility model relates to the technical field of counterweights, in particular to a counterweight for agricultural machinery that is convenient to disassemble. Background Art

[0002] In the field of agricultural machinery, counterweights are widely used components at the front of the agricultural machinery vehicle head. Their key role is to adjust the stability and balance of the agricultural machinery during the operation process to ensure that the agricultural machinery can smoothly and efficiently perform various agricultural tasks, thereby improving the efficiency and quality of agricultural production.

[0003] However, traditional counterweights often adopt an integrated design. After installation, it is difficult to adjust their weight and position, which greatly restricts the adaptability and flexibility of agricultural machinery in various operating environments and conditions. In addition, since they are fixed to the agricultural machinery vehicle head through fastening elements such as bolts, a large amount of time and effort are required for disassembly, and it is also easy to damage the fastening elements and the counterweights themselves, thereby increasing the maintenance cost.

[0004] Therefore, in view of the situation that traditional counterweights often adopt an integrated design, it is difficult to adjust their weight and position and a large amount of time and effort are required for disassembly, a counterweight for agricultural machinery that is convenient to disassemble can be designed. Through the cooperation of the locking structure and the counterweight overlapping plate, not only can the weight of the counterweight overlapping plate be flexibly adjusted, but also the quick disassembly and assembly of the counterweight overlapping plate are greatly facilitated. Summary of the Utility Model

[0005] In order to overcome the problems that traditional counterweights often adopt an integrated design, it is difficult to adjust their weight and position and a large amount of time and effort are required for disassembly.

[0007] Preferably, the box body is the main structure of the entire counterweight device, made of high-strength and corrosion-resistant metal materials. The side plates play a protective and supporting role and are also used to fix the top plate. The top plate is a closed structure at the top of the side plates, made of lightweight but strong materials such as aluminum alloy or stainless steel plates. The cross bar plays a supporting role and also provides an installation foundation for the guide rod. The guide rod is perpendicularly intersecting with the cross bar and is fixedly connected to the cross bar. The outer wall of the guide rod is smooth and flat, and closely fits with the hole grooves in the overlapping counterweight plates, providing a guiding function for the sliding connection of the overlapping counterweight plates. The overlapping counterweight plates are key components in the counterweight device, composed of multiple layers stacked together. By adjusting the number and layers of the overlapping counterweight plates, precise adjustment of the total weight of the counterweight can be achieved. The locking structure is used to fix the overlapping counterweight plates. The design of the locking structure enables operators to easily and quickly complete the locking and unlocking operations when disassembling and replacing the overlapping counterweight plates, ensuring that the overlapping counterweight plates do not fall off during operation.

The connecting plate serves as a supporting component of the locking structure, providing a stable connection point for the locking shaft. The locking holes provide a channel for the insertion of the locking shaft. This design enables the locking shaft to easily fix the overlapping plate to the first moving seat and the second moving seat, thereby achieving the locking function. When it is necessary to adjust the position of the overlapping plate, simply rotate the bidirectional threaded rod to drive the first moving seat and the second moving seat to move to achieve the unlocking function.
