Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and particularly to a cargo box and an agricultural machinery. Background Art

[0002] In recent years, with the continuous acceleration of agricultural modernization, various structures of agricultural machinery, such as tractors, have been more and more widely used in agricultural production.

[0003] The currently widely used tractors have various structures. Generally, they include a tractor head, a frame connected to the tractor head, and a cargo box is arranged on the frame. When the tractor head works, the cargo box is driven to travel through the frame, and the goods are placed in the cargo box to achieve the purpose of transporting goods. However, for the currently used tractors, the size of the cargo box is fixed and cannot be adjusted according to the needs regardless of the type of goods transported. Therefore, it is not convenient to use and the practicability is relatively poor.
