The discharge port (81) and the discharge port (83) at the lower end of the feeding device are the positions where the materials leave the device. The discharge port (81) at the lower end of the feeding device is welded to the feed port (85) of the guide, and the materials leave the earthworm feeding box (77) from here and are put into the field through the discharge port (81) at the lower end of the feeding device and the feed port (85) of the guide. The gear hole (82) on the right end cover of the unloading device is a hole reserved for the installation of the worm; The upper feeding port (84) of the material discharging device is located at the upper end of the material discharging mechanism, and the material enters the material discharging device (69) from the seed box. The earthworm feeding box (77) and the earthworm feeding box base (78) include an earthworm feeding box loading port (86), a buckle joint (87) at the bottom of the earthworm feeding box, a pin opening (88) at the base of the earthworm box, a buckle joint (89) at the base of the earthworm feeding box and a pin (90); The earthworm feeding box loading port (86) receives the material; The buckle joint (87) at the bottom of the earthworm feeding box and the buckle joint (89) at the base of the earthworm feeding box on the base (78) of the earthworm feeding box are buckled with each other to fix the earthworm feeding box (77) on the base (78) of the earthworm feeding box; The earthworm feeding box base (78) is composed of a bottom plate and a pin, and the pin (90) connects the earthworm box base pin openings (88) of two earthworm box bases (78). According to the above connection method, 14 earthworm boxes are connected head to tail in sequence to form a ring structure; The soil covering element (70) comprises a double-disc soil covering device (91), a double-disc soil covering device bracket (92), a soil covering device fixing port (93) and a soil covering device-chassis connecting port (94); The double-disc soil cover bracket (92) is installed in the soil cover fixing opening (93); The double disc soil cover (91) is welded to both ends of the double disc soil cover bracket; The soil cover device-chassis connection port (94) is connected to the soil cover element fixing beam (19) at the rear of the chassis by bolts.
