Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a ridging machine. Background Technology

[0002] In agriculture, ridge making refers to creating raised, strip-shaped platforms above the ground in a field, spaced at certain intervals and widths. The upper part is called the "ridge platform," and the furrows between the ridges are called "ridge furrows." Ridging makes the soil looser and more porous, increasing soil aeration and drainage, which is beneficial for plant root growth and development. At the same time, ridge making allows farmers to manage crops more conveniently, including fertilizing, irrigating, weeding, and harvesting. The height and shape of the ridges help prevent waterlogging and promote drainage, avoiding waterlogging of plant roots and reducing the risk of pests, diseases, and root rot caused by excessive moisture.

[0003] Chinese patent CN118947255A discloses a ridging machine, including a second transmission chain connected to the end of a ridging column. A circular arc groove is formed through the interior of a limiting member, and both ends of the ridging column are embedded in the circular arc groove. A hidden arc plate is movably installed inside the ridging column, and a water cylinder is fixedly installed inside the ridging column. By opening the hidden arc plate, the water cylinder is exposed, and the ridging column moves upward along the path of the circular arc groove until it reaches its limit position. A fixed structure fixes the limiting member and the ridging column at this point. During the forward and backward movement of the ridging column, the second transmission chain always maintains a transmission relationship with the ridging column.

[0004] However, since the second drive chain is connected to the end of the ridging column, a large amount of impurities can get caught in the connection between the two parts due to the contact between the ridging column and the ground. This accelerates the wear of the second drive chain, reduces its service life, and can even cause it to jam. Furthermore, chain drives occupy space, making the device less compact and hindering the arrangement of other functional components, such as sowing components, thus limiting the functionality of the ridging machine.
