Amplitude-modulation hydraulic overturning plow frame

Abstract

The invention discloses an amplitude-modulation hydraulic overturning frame which is used for solving the problems that the connection strength between a plow main shaft and a plow frame triangular frame is not high, and the plow triangular frame cannot be overturned normally after amplitude modulation in the existing amplitude-modulation hydraulic overturning frame. The amplitude-modulation hydraulic overturning frame comprises a traction device, an amplitude modulation device, a power device, an overturning device and a triangular frame, wherein the power device comprises an oil cylinder hanging frame, a first overturning oil cylinder, a second overturning oil cylinder and an oil cylinder hoisting seat, and L-shaped plates are arranged at the piston rod ends of the first overturning oil cylinder and the second overturning oil cylinder; the amplitude modulation device comprises a guide rail sleeve, an upper guide rail, a lower guide rail, a main cross beam and an amplitude modulation oil cylinder, wherein the guide rail sleeve is internally provided with an upper cylindrical guide rail and a lower cylindrical guide rail, and guide sleeves are arranged outside the upper cylindrical guide rail and the lower cylindrical guide rail. The frame can be used for adjusting the left plow amplitude or the right plow amplitude of an integral plow according to the plowing demands of a user, and also can be rotated normally after amplitude modulation, and has the characteristics of simple structure, convenient and time-saving amplitude modulation, flexible overturning and stable amplitude modulation performance.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an amplitude modulation hydraulic turning plow frame. Background technique [0002] The amplitude modulation hydraulic pressure flip plow of present market sale, its shortcoming is: one, the plow main shaft is welded and connected with the guide rail overcoat that lays flat. This design greatly weakens the connection strength between the plow main shaft and the plow frame tripod, and the welded parts are prone to desoldering and tearing. Second, the plow tripod can no longer be turned over normally after the amplitude modulation. 3. Since the tripod of the plow is limited by the angle screws set on both sides of the traction frame, the angle of inclination of the tripod of the plow increases after amplitude adjustment, resulting in an increase of the angle of inclination of the plow column, which makes it very easy for the whole machine to appear when plowing in...
