The roller surfaces of the two rollers are in rolling contact. The garlic cloves in the upper seed guide tube 12 are blocked on the roller surfaces of the first roller 143 and the second roller 153.

The internal space of the first garlic clove accommodating cavity 1431 and the second garlic clove accommodating cavity 1531 can only accommodate one garlic clove when engaging, so that the single garlic clove can be clamped. The first garlic clove accommodating cavity 1431 and the second garlic clove accommodating cavity 1531 gradually separate when approaching the upper end of the lower seed guide tube 13, so that the clamped garlic clove falls into the lower seed guide tube 13. Such a reciprocating cycle realizes the single garlic clove intermittent seeding, and the seeding speed is controlled by the rotating speed of the first roller 143 and the second roller 153.

[0050] When the garlic clove with a larger particle size or foreign matter mixed in the garlic clove to be seeded passes between the first roller 143 and the second roller 153, the first roller 143 and the second roller 153 can be elastically separated by a certain distance to avoid crushing the garlic clove or damaging the roller surface of the first roller 143 and the second roller 153, thereby achieving the automatic protection function.

[0054] One end of the push rod 26 is fixedly connected with a fork 261, the fork 261 moves cyclically with the swing action of the push rod 26, and the movement path of the fork 261 is a ring-shaped one-way path (not a reciprocating path), as shown in Figure 6 The fork 261 passes through the elastic chuck 131 from top to bottom in the process of swinging, and the garlic cloves clamped in the elastic chuck 131 can be quickly pressed down, which is similar to the action of inserting by hand, so that the garlic cloves can be inserted into the soil in a vertical state with the scales upward and the roots downward, and the fork 261 is outside the elastic chuck 131 in the process of swinging from bottom to top, so that the next garlic clove in the lower guide tube 13 can be prevented from falling into the elastic chuck 131.

[0055] The transmission 30 is arranged between the seed metering mechanism 10 and the inserting mechanism 20, the input end of the transmission 30 is drivingly connected with the power mechanism of the seeding machine, the output end of the transmission 30 is drivingly connected with the first transmission shaft 144 in the seed metering mechanism 10 and the first rotating shaft 22 in the inserting mechanism 20, respectively, for driving the first roller 143 and the second roller 153 in the seed metering mechanism 10 to rotate, performing single-grain intermittent seed metering, and driving the push rod 26 and the fork 261 in the inserting mechanism 20 to swing, performing garlic clove inserting, the seed metering speed of the seed metering mechanism 10 and the inserting speed of the inserting mechanism 20 are matched with each other, that is, the seed metering mechanism 10 performs one seed metering action for each garlic clove, and the inserting mechanism 20 performs one inserting action, and the above actions are repeated, so that the continuous automatic seeding of garlic cloves is realized.
