[0001] This utility model belongs to the field of soil turning machine technology, and specifically relates to a soil turning and fertilizing machine with a buffer mechanism. Background Technology

[0002] Patent application number 202222668574.9 discloses a furrowing plow height adjustment mechanism for an agricultural tillage and fertilization machine, relating to the field of tillage machine technology. It includes a mounting frame with wheels, a furrowing plow and a fertilizer hopper mounted on the mounting frame, and an adjustment component for adjusting the height of the furrowing plow and fertilizer hopper on the mounting frame. The mounting frame also has a positioning component to prevent the adjustment component from rotating. In this invention, the adjustment component and the positioning component work together, and the adjustment rod and the fixed threaded sleeve engage to allow the adjustment rod to slide relative to each other, thus adjusting the height of the furrowing plow. Compared to the existing method of fixing with bolts and positioning holes, it eliminates the need to lift the furrowing plow and fertilizer hopper upwards for fixing, and also eliminates the need to visually observe the position of the positioning holes, making operation simple.

[0003] However, the bottom surface of the soil for turning and fertilizing is uneven, and the walking mechanism is fixedly installed on the mounting frame, which causes the furrowing plow and fertilizer bucket to move up and down continuously, resulting in constant changes in the depth of turning and fertilizing, thus affecting the effect of turning and fertilizing. Utility Model Content

[0004] In view of this, the present invention provides a soil turning and fertilizing machine with a buffer mechanism. When the walking mechanism walks on an uneven bottom surface, the elastic component realizes the buffer function. At the same time, the sliding rod moves along the sliding tube to realize the height adaptive adjustment function, so as to prevent uneven ground from causing different soil turning and fertilizing depths.
