Description

Technical Field

[0001] This utility model relates to the field of cotton planting technology, specifically to a trenching, soil covering, and drip irrigation device for cotton planting. Background Technology

[0002] Cotton is an important economic crop in my country, and the cotton-growing area in Xinjiang has a vast planting area. Currently, drip irrigation technology is often used in cotton planting to save water and increase yield. However, the existing work of trenching, covering soil, and laying drip pipes in cotton planting mostly relies on manual labor or simple machinery. This is not only labor-intensive and inefficient, but also has problems such as inconsistent laying depth, easy exposure of drip pipes, or burying them too deep. These problems seriously affect cotton growth and irrigation effects, and innovative equipment is urgently needed to solve these problems.

[0003] The existing equipment lacks a convenient depth adjustment mechanism, making it impossible to flexibly and accurately adjust the furrowing depth. This fails to meet the differentiated requirements for furrowing depth in different cotton planting scenarios, such as different varieties and soil fertility. The low furrowing accuracy affects planting quality, and the overall precision and efficiency of the equipment are insufficient. The various parts of the equipment are designed in isolation and do not form a collaborative system, resulting in poor comprehensive performance and difficulty in adapting to the requirements of modern cotton planting for precision and efficiency.

A hydraulic cylinder drives the hydraulic extension... The retractable column allows the sliding block to move up and down along the fixed rod, thereby adjusting the depth of the furrowing cutter to meet the furrowing depth requirements of different cotton planting scenarios and improving furrowing accuracy. The first covering wheel on the first mounting frame and the second covering wheel on the second mounting frame enable timely covering operations after furrowing. The two sets of covering wheels work together to make the covering more uniform and compact, avoiding the uneven covering problem that occurs during manual covering.
