Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting furrowing machinery, in particular to a ridge-forming furrowing device for sweet potato cultivation. Background Art

[0002] Before planting sweet potatoes, the fields need to go through plowing, rotary tillage, and ridge formation. Plowing and rotary tillage are important processes in agricultural soil cultivation. They can turn the soil from the bottom of the cultivated layer to the surface, fully expose it to the sun, and effectively kill underground pests. Ridging increases the surface area, absorbs and dissipates heat quickly, improves photosynthetic efficiency, improves soil air permeability, and is conducive to the development of crop roots. When cultivating sweet potatoes, it is necessary to simulate the planting environment and ridge the land.

[0003] In the existing technology, a utility model with announcement number CN220023550U provides a ridging device for sweet potato planting. In this application, a connecting arm is connected to a rotary tiller through a connecting assembly, and the ridging device can be installed on the rotary tiller as needed. When the rotary tiller is moving, the ridging device moves forward with the rotary tiller, and the soil layers are separated to form furrows by inserting the ridging columns into the soil, while the two plowshares push the soil to both sides to form ridges behind the ridging columns as the rotary tiller moves forward, thereby achieving the purpose of simultaneous rotary tillage and ridging and improving work efficiency. The movable setting of the ridging columns on the connecting arm can adjust the depth of the ridging columns inserted into the soil layer to adjust the ridge depth. The rotatable setting of the plowshare on the ridging columns and the setting of the adjusting assembly can drive the two plowshares to rotate through the adjusting assembly to adjust the distance between the movable ends of the two plowshares, thereby adjusting the ridge spacing as needed. Therefore, the present application can improve the efficiency of crop planting work, and can adjust the ridge depth and ridge spacing as needed, and has a wide range of applications.

[0004] However, it has the following defects: First, the opening and closing angle of the plowshare is adjusted by an adjusting rod, and the two ends of the adjusting rod are respectively hinged to the adjusting block and the plowshare, so that the adjustment angle of the plowshare is very limited; Second, the plowshare is behind the ridging post, plow post, and plow shovel. After the soil is separated by the plow shovel and plow post, it contacts the plowshare and is easy to leak from the gap between the upper and lower positions of the support block to the area between the two plowshares, affecting the forming effect of the ridge platform and the furrow.
