Description

Technical Field

[0001] This utility model relates to the field of plow blade assembly design technology, specifically a plow blade assembly for a tiller used in tomato field planting. Background Technology

[0002] The plow blades are installed in front of the main plow body. Their function is to cut neat furrows vertically, reducing the resistance of the main plow body and lessening wear on the cutting edge. They also cut weeds and stubble, improving the quality of mulch. There are two types of plow blades: straight and round. Straight plow blades are simple in structure and durable, but they have higher working resistance. Round plow blades, on the other hand, roll and cut the soil, resulting in lower resistance and less entanglement with weeds, making them widely used in power plows. Round plow blades also come in three forms: ordinary cutter discs, corrugated cutter discs, and notched cutter discs. In tomato cultivation, to increase yield, regular plowing is necessary. To facilitate plowing, a plow blade assembly for tomato field cultivators is required.

[0003] The existing tillage blade assembly of the tomato field planter is inconvenient to disassemble and assemble, which affects the replacement of parts and the use of the machine. It is also inconvenient to break up the soil, which affects the efficiency of use. Utility Model Content
