Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to an adjustable sowing furrow opener. Background Art

[0002] When digging furrows on the forest bed, the planting area is narrow and long, and the number of furrows is large. It is not suitable for manual furrow openers such as CN201922452013.3 and CN201621008787.7. The number of furrows is small, and it is not suitable for large-scale machinery powered by steam or diesel. Generally, only rake teeth can be used for furrowing. When target teeth are used for furrowing, the furrowing depth is shallow, the number of furrows is fixed, the degree of matching with the bed surface is low, and the use efficiency is low.

[0003] The Chinese patent with patent number CN218920946U proposes an adjustable seeding furrow opener, including a connecting rod, a cross bar is arranged on the connecting rod, and the cross bars are two. A plurality of adjustment sleeves are arranged on the two cross bars. The adjustment sleeves and the cross bars can be slidably adjusted. A first adjusting bolt is arranged on the adjusting sleeve. The end of the first adjusting bolt passes through the adjusting sleeve and contacts the cross bar. A plurality of connecting hooks are arranged on one side of the connecting rod, and rake teeth are arranged at the bottom of the connecting hook. The beneficial effect is that the adjustment is flexible and it is suitable for furrowing for morel cultivation on the forest bed.

[0004] Although the above patent can complete the trenching process on the forest border, its connecting rod and connecting pipe are connected by bolts. When the length of the connecting rod needs to be adjusted, two sets of bolts need to be removed from the connection between the connecting pipe and the connecting rod, and after the connecting rod is pulled out to the corresponding position, the two sets of bolts need to be tightened to complete the reinstallation of the connecting rod and the connecting pipe, which is a relatively cumbersome operation.
