Working principle of the invention:

Referring to Figures 1 to 4, the working principle of the new vibrating ditching and fertilizing machine for saline-alkali grassland of the present invention is as follows. The traction force is input by the traction machinery, and is transmitted to the gantry (1) and suspension frame (2) through the three-point suspension system, and then transmitted to the active fertilization kit (B) and active trenching kit (C) through the frame (A) , driving the entire saline-alkali grassland vibrating ditching and fertilizing machine forward.

The vibration motor (4) is located at the left rear of the frame (A) and is welded above the middle part of the left end of the overall welding frame (3). It has an excitation frequency of 100W, an excitation force of 50kg, and a vibration frequency of 3000r/min, which can provide Relatively stable vibration frequency, vibration amplitude, and high vibration frequency, not affected by elastic components, can reduce soil adhesion on the trencher, thereby achieving effective drag reduction;

Referring to Figures 5 to 8, the power of the active fertilization kit (B) is connected to the No. 1 hydraulic motor (22), which drives the main shaft (21) to rotate through the casing. The main shaft (21) drives the main shaft casing (24) to rotate, driving the fertilizer. The transport gear (23) rotates, and fertilizer enters the upper port of the fertilizer transport gear (23) from the fertilizer box (20). The rotation of the fertilizer transport gear (23) sends the fertilizer to the lower port, flows into the feed pipe (16), and finally flows from the fertilizer box (20) to the lower port. Outflow comes from the lower port of the feeding pipe (16).

The trencher cutter head (17) is designed with a downward convex curved edge and an acute angle, and has minimum trenching resistance. After the notched disc rake blade actively breaks the soil, it can push away the broken soil and ensure a good trench shape, which can effectively Reduce the energy consumption of agricultural machinery and improve the operating efficiency of agricultural machinery;

Referring to Figures 8 to 14, the power of the active trenching kit (C) is connected to the No. 2 hydraulic motor (26) and transmitted to the center wheel (55) through the motor transmission spline (33). The center wheel (55) drives the outer ring The three planet wheels (54) rotate, and the planet carrier (52) driven by the planet wheels (54) rotates. The planet carrier (52) drives the transmission shaft seat (45) to rotate through splines, and drives the segmented shaft end splines (51). Rotate, power is transmitted between the segmented shafts (28) through the inter-shaft transmission key (57) of the coupling set (31), and the notched disc rake blade (30) is installed on the segmented shaft (28) and rotates accordingly. This achieves the purpose of actively cutting the soil.

The diameter of the notched disc rake blade (30) is 500mm, the effective farming width is 150mm, and the deflection angle is 23 degrees. The zigzag-shaped notch on the edge can better break up the soil and prevent compaction, which is beneficial to maintaining the permeability of the soil. and looseness, especially important in improving soil drainage and reducing moisture accumulation in humid areas or high humidity conditions. In addition, the notched disc harrow performs well at handling weeds and stubble, with the notched edge enabling better cutting and handling of plant debris, increasing the efficiency of weeding and stubble treatment, and effectively clearing farm surfaces.
