[0002] The existing hole seeding and fertilization methods, whether manual or mechanical, all use the method of applying fertilizers in spots or strips on the sides of hole seeding seeds, which not only wastes fertilizers but also has low fertilizer utilization. In recent years, in order to improve the efficiency of fertilizer use, agronomy has proposed a method of applying fertilizers in a circular manner on the outer side of hole seeding seeds. This method greatly improves the efficiency of fertilizer use, but the manual operation method not only has great difficulty and labor intensity, but also has low operation efficiency and poor operation quality. Therefore, it is very necessary to develop mechanized operation machinery suitable for hole seeding and circular fertilization. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine the actual needs of promoting and applying the agronomic methods of hole seeding and circular fertilization, and develop a combined unit of hole seeding and circular fertilization to achieve good operation quality, high efficiency, strong applicability, high degree of commonality, and meet the needs of mechanized operation of hole seeding and circular fertilization.

A spiral groove is provided on the outer wall of the tubular core body, and the seed delivery pipe connects the seed discharge port of the seed metering device with the hole-type seed discharge channel of the tubular core body. A conical fertilizer distribution plate is fixedly installed on the outer wall of the lower side of the tubular core body. The seed hole former is fixedly equipped on the lower end of the tubular core body and cooperates with the hole-type seed discharge channel. A cylindrical shell can be movably mounted on the outer side of the tubular core body through the insertion and cooperation of the guide plate and the spiral groove. A cone is fixedly installed on the lower end of the cylindrical shell body, located on the outer side of the conical fertilizer distribution plate. A conical fertilizer expansion shell is provided, and a spacing is provided between the tubular core and the cylindrical shell and between the conical fertilizer distribution plate and the conical fertilizer expansion shell to form an annular fertilizer delivery channel. The fertilizer delivery bucket connects the fertilizer discharge port of the fertilizer discharger with the annular fertilizer delivery channel. An annular fertilizer groove ditching shovel is fixedly installed on the lower side wall of the conical fertilizer expansion shell by bolts. The annular fertilizer groove ditching shovel cooperates with the annular fertilizer delivery channel. A cylindrical cone bearing is fixedly mounted on the outside of the cylindrical shell. A vertically arranged driving connecting rod is fixedly connected to the outer ring of the cylindrical cone bearing.

The tubular core 28 has a spiral groove 29 on the outer wall of the tubular core 28. The seed delivery tube 17 connects the seed discharge port of the seed meter 21 with the hole-type seed discharge channel 26 of the tubular core 28. A conical fertilizer distribution plate 25 is fixed on the outer wall of the lower side of the tubular core 28. The seed hole former 12 is fixed on the lower end of the tubular core 28 and cooperates with the hole-type seed discharge channel 26. The cylindrical shell 8 can be movably mounted on the outer side of the tubular core 28 through the insertion and cooperation of the guide plate 27 and the spiral groove 29. At the lower end of the cylindrical shell 8, at the conical fertilizer distribution plate 25, a cylindrical shell 8 is provided. The outer part of the plate 25 is fixed with a conical fertilizer expansion shell 9, and a spacing is provided between the tubular core 28 and the cylindrical shell 8 and between the conical fertilizer distribution plate 25 and the conical fertilizer expansion shell 9 to form an annular fertilizer delivery channel 24. The fertilizer delivery bucket 7 connects the fertilizer discharge port of the fertilizer discharger 5 with the annular fertilizer delivery channel 24. An annular fertilizer groove ditching shovel 11 is fixed on the lower side wall of the conical fertilizer expansion shell 9 by bolts 10. The annular fertilizer groove ditching shovel 11 cooperates with the annular fertilizer delivery channel 24. A cylindrical cone bearing 15 is fixedly mounted on the outside of the cylindrical shell 8. The driving connecting rod 16 arranged vertically is connected to the annular fertilizer delivery channel 24. The outer ring of the cylindrical tapered bearing 15 is fixedly connected, and the guide limit rod 6 and the spring shaft 13 are respectively fixedly installed on the upper side and the bottom end of the driving connecting rod 16, the guide limit rod 6 can be slidably inserted on the column of the single frame 3 up and down, and the spring shaft 13 can be movably inserted on the bottom beam of the single frame 3 up and down, and the pressure spring 14 is sleeved on the spring shaft 13.

Driven by the conical fertilizer expansion shell 9 and the bolt 10, the annular fertilizer ditch shovel 11 rotates to complete the ditching operation of the annular fertilizer ditch on the land outside the pit seed. At this time, the fertilizer discharged by the fertilizer discharger 5 is discharged into the annular fertilizer ditch opened by the annular fertilizer ditch shovel 11 through the fertilizer bucket 7 and the annular fertilizer channel 24, completing the fertilizer circular application operation. Afterwards, the single frame 3 moves upward as a whole, breaks away from the contact with the ground, moves forward with the sowing and fertilizing machine, and moves downward again. At this time, under the action of the pressure spring 14, the cylindrical shell 8 and the annular fertilizer ditch shovel 11 are driven by the connecting rod 16 and the cylindrical cone bearing 15 to make an upward return movement relative to the tubular core 28, and the cycle is completed in sequence to complete the continuous operation.
