Lightweight leveling truss for liquid manure fertilizer applicator

Abstract

The utility model relates to the field of agricultural machinery, and discloses a lightweight leveling truss for a liquid manure fertilizer applicator, which is characterized by comprising a connecting and positioning frame and a leveling frame. The connecting and positioning frame is connected with the rear end of the traction tank car in a hanging mode, the whole posture is synchronous with the connecting and positioning frame, and the leveling frame is achieved by driving the frame to rotate through a leveling oil cylinder. The leveling truss is designed for solving the problem that the overall stability is reduced due to large load of a hydraulic oil cylinder caused by large occupied space and overlarge mass of a main body part of a leveling truss of an existing liquid fertilizer applicator. By means of the combined structure for connecting the positioning frame and the leveling frame, accurate active leveling of the truss can be achieved under the condition that the space occupied by the leveling truss is small, and meanwhile the requirement for the supporting strength of an operation machine tool is met.

[0023] The working principle of the embodiment is as follows: before operation, an operator suspends the utility model from a tank truck through a suspension point (15) and connects the truss through a rotary pair (5) to the folding arms on both sides. When the liquid manure applicator is in operation, the offset angle of the truss and the ground is read by external devices such as ultrasonic sensors and angle sensors. If the truss and the ground are in a left-inclined state, the left leveling oil cylinder (3) is elongated or the right leveling oil cylinder (3) is shortened to make the leveling frame (2) rotate to the right around the center frame (11) to achieve the purpose of the machine tool adhering to the ground. If the truss and the ground are in a right-inclined state, the left leveling oil cylinder (3) is shortened or the right leveling oil cylinder (3) is elongated to make the leveling frame (2) rotate to the left around the center frame (11) to achieve the purpose of the machine tool adhering to the ground. During the leveling process, the connecting positioning frame (1) always keeps the posture synchronous with the tank truck, and the leveling oil cylinder (3) and the auxiliary leveling connecting plate (4) ensure that the rectangular frame (21) and the movable clamping plate (12) of the leveling frame (2) are in the same plane and move along the calculated trajectory.
