Machine for making large ridges

The utility model relates to a machine for making large ridges, which comprises a ground wheel mechanism, a main beam frame, and a four-link profiling mechanism. The utility model is characterized in that the longitudinal beam of the four-link profiling mechanism is connected with a main plough share working part; a left and a right and an upper soil ploughs are connected with the longitudinal beam of the four-link profiling mechanism at both sides of the main plough share working part, and the left and the right and the upper soil ploughs are arranged in front of the main plough share working part; the tail end of the longitudinal beam is connected with a shaping harrow and a semi-shaping harrow through a supporting connecting component. The utility model has the advantages that the mechanization of making large ridges can be realized; the labor intensity can be reduced; the work efficiency can be enhanced; the utility model is convenient to popularize the new technology of twin-row large maize ridges, and is favorable to increase the product and the harvest of crops.
