Description

A subsoiler with staggered vibration

technical field

The invention relates to a soil tillage equipment, in particular to a subsoiler which can vibrate forwardly, backwardly, upwardly and downwardly.

Background technique

There are a lot of machinery used for farming in the society, most of which have a shallow depth of cultivation, especially after years of repeated cultivation, the soil has a hard plow bottom layer, which prevents crops from fully absorbing water and fertilizer resources, resulting in slow growth of crops and poor harvested fruits. Not full and less productive. In the subsoiling technology produced for this reason, most subsoilers need to provide a large power source due to the deep cultivation depth, which is inconsistent with China's current national conditions where medium-sized tractors account for the majority, thus seriously restricting the development of subsoiling technology .

Using vibration subsoiling technology is a good solution to the above problems. The vibration subsoiler is driven by the power output shaft of the tractor to reduce the tillage resistance, making it suitable for medium-sized tractors. Most of the deep loosening shovels of the subsoiling machine are arranged in a row, the whole machine is not compact enough, and the power consumption is also large, especially when the vibration of the subsoiling shovel is completed during the subsoiling process, the vibration of the machine itself is too large, and the noise and vibration make the operation The environment is extremely harsh, which seriously affects the operation of the manipulator. When the vibratory subsoiler is in actual operation, the four subsoilers vibrate in the same direction at the same time, causing the resistance to change sharply during the process of squeezing the soil. The resistance seriously affects the progress of the work.
