A potato zero-speed hole seeding fertilization device, wherein a rotary crank 17, a fixing pin 14 and a double-rod connecting rod 12 are respectively installed on the front of the mounting plate 15; a power input sprocket 18 is installed on the back of the mounting plate 15 at a position coaxial with the rotary crank 17, and a precision metering pump 16 is fixed to the mounting plate 15 below the power input sprocket 18 through an angle steel; a double-rod rocker arm 10 is hingedly mounted on the rotary crank 17 through a notch plate 13, and the fixing pin 14 passes through the notch plate 13. 3, one end of the double-bar rocker arm 10 is connected to the double-bar connecting rod 12 by being rotatably hinged with the trapezoidal connecting plate 11, and the other end of the double-bar rocker arm 10 is hinged to the hole sowing device mounting seat 4, and the hole sowing device plate I8 and the hole sowing device plate II9 are respectively hung and hinged at the lower part of the hole sowing device mounting seat 4 symmetrically and relatively swingably through the hole sowing device plate connecting rod 5, and the hole sowing device plate I8 and the hole sowing device plate II9 are mutually closed or mutually opened ... The upper opposite ends of the seeding device plate II 9 are respectively connected to the Z-shaped lifting lever 3 through the hinged lifting rod 6. The middle part of the Z-shaped lifting lever 3 is rotatably hinged to the lifting lever base 2. The lifting lever base 2 is fixedly mounted on the seeding device mounting seat 4. The two Z-shaped lifting levers 3 are respectively hinged to the two ends of the push rod seat 19. The roller push rod 21 is fixedly mounted on the push rod seat 19 and forms a cylindrical cam mechanism with the cylindrical cam 22 coaxially connected to the inside of the push rod seat 19. The bottom of the cylindrical cam 22 The end is connected with the output shaft key of the motor 23 fixedly installed inside the hole seeder mounting base 4; one end of the liquid fertilizer pipe 7 is respectively connected with the liquid fertilizer nozzle 20 fixedly installed inside the hole seeder plate Ⅰ8 and the hole seeder plate Ⅱ9, and the tube body of the liquid fertilizer pipe 7 is installed in the groove of the inner wall of the hole seeder plate Ⅰ8 and the hole seeder plate Ⅱ9, and then the double tubes are combined into a single tube, which passes through the hole on the upper surface of the hole seeder mounting plate 4 and is connected to the liquid outlet of the precision metering pump 16; the inoculation cylinder 1 is fixedly installed at the central through hole of the hole seeder mounting base 4.

[0014] During operation, external input rotational power drives the rotary crank 17 to rotate through the power input sprocket 18, and the rotary crank 17 drives the notch plate 13 to swing around the fixed pin 14, and under the coordinated control of the notch plate 13, the double-rod connecting rod 12, the trapezoidal connecting plate 11 and the double-rod rocker arm 10, the seed drill mounting seat 4 and its upper parts are driven to perform rotational motion. When the inoculation cylinder 1 follows the seed drill mounting seat 4 to reach the most point position of the periodic motion, the inoculation cylinder 1 receives a seed potato.
