RESEARCH ON THE WORLD STATE OF TECHNIQUE THROUGH PATENTS WHICH REFERS TO MOULDBOARD THAT EQUIP THE PLOUGHS WITH CORPS AND MY CONTRIBUTION TO THE MODERNIZATION OF THE MOULDBOARDS

Abstract
From assemblies of parts that form the plow with moldboard, the part of the plow which consumes most of the energy is the mouldboard (50-60% of the plowing work).
From research through patent in the field of mouldboard for plows, which I have conducted revealed that in the world today there are 11 inventions most representative. These inventions generally contain known elements and technical elements of the original to their authors and inventors that they get the record (and they claim them in the Chapter "Claims") which must necessarily be part of any deposit submitted to obtain a patent.
From the analysis of the technical attributes presented in the table shows that the global study of the mouldboard has not enjoyed particular attention. From the library of patents of OSIM Romania if in the motor field are some hundreds of inventions in the field of mouldboards are only 11.
Remember as a new thing, worthy of recognition, the German patent DE3318159A1, author Hans Wacker in which the moldboard is made of strips (bands) with the advantage that it reduces the moldboard area by 50% and a disadvantage that the bands (strips) are unstable during work.
Based on these findings I tried to achieve an improvement of the mouldboards with significant economic and practical effects.

Key words: mouldboard, invention, claim, strips (bands), the economy
