Description

Technical Field

[0001] This utility model relates to the technical field of tillage root breaking devices for agricultural machinery, specifically a tillage root breaking device for agricultural machinery. Background Technology

[0002] Agricultural arable land refers to land specifically used for growing crops and regularly cultivated, capable of normal harvesting. During the harvest season, after farmers harvest mature crops from the arable land, the roots and stems of the crops remain underground. Due to the netting effect or anchoring effect between plant roots, these remaining crop roots and stems in the soil exert a cohesive force on the field soil. As a result, it is difficult for crop seeds to penetrate the soil when sowing. Although planting can be done by digging holes before sowing, the seeds planted in this way will be hindered by the resistance of the remaining roots and stems when taking root, which is not conducive to the growth of newly planted crops. The existing method is mostly to use rotary tillers to break up the roots. Although this method achieves the purpose of breaking up the roots, it is not ideal.

[0003] A root-breaking device for tilling agricultural machinery, disclosed in Chinese Utility Model Patent Application Publication CN216058149U, has advantages such as improved protection of the device body and convenient and quick use. However, it also has some drawbacks: First, the device relies solely on a rotating shaft and auger to break up roots inside the soil. In actual use, this method may not be very efficient, and residual roots cannot be removed promptly after being broken up, requiring separate cleaning afterwards. Second, when encountering hard soil, the root-breaking mechanism is more susceptible to damage. Prolonged wear and tear on the tillage blades can lead to their failure, necessitating frequent replacement and maintenance. Utility Model Content
