Technical Field

[0001] The utility model relates to the technical field of agricultural planting equipment, in particular to a trenching machine for agricultural planting. Background Art

[0002] Agriculture can provide basic products to support the construction and development of the national economy. Planting refers to plant cultivation, including the cultivation of various crops, trees, fruit trees, flowers, medicinal and ornamental plants. Agricultural planting is mainly used to grow organic matter such as vegetables and fruits. Since the land needs to be ditched before planting, a special ditching machine is needed.

[0003] A Chinese utility model patent with the announcement number CN220108635U discloses a furrowing device for agricultural planting, which drives a pulley to rotate through a driving motor, and drives a support shaft to rotate through the transmission action of a transmission belt, and drives a soil breaking disc and soil breaking teeth to rotate through the rotation of the support shaft, thereby breaking the ground to prevent soil compaction from affecting the efficiency of furrowing by a plow. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, the soil on both sides of the excavated trench is relatively loose, and the device lacks an integrated structure that can clean the soil accumulated on both sides of the trench, which makes it easy for the soil to collapse and fall back into the trench, thus affecting the trenching effect. For this reason, we provide a trenching machine for agricultural planting. Utility Model Content
