Abstract

The utility model belongs to the technical field of agricultural planting equipment relates to vegetables fixed planting plant distance adjustable mechanical device. The device is by push car subassembly, transmission subassembly, push subassembly and unfolding subassembly constitute. Push car subassembly realizes device movement, transmission subassembly transmission drive force, push subassembly adjusts the aperture mechanism specification in unfolding subassembly, and unfolding subassembly completes the hole digging and hole expanding operation. Through setting up different installation hole position installation unfolding subassembly on the rolling ring, can adapt to different planting spacing demand. The device solves the problem that the vegetable planting process is difficult to accurately adjust fixed planting plant distance and the problem that the soil is easy to collapse after digging hole and influences planting, improves the accuracy of vegetable planting fixed planting plant distance adjustment and planting efficiency.
