In order to achieve the purpose, the invention provides the following technical scheme to realize the purpose: a seed sowing device of a combined type community seeder comprises a shell, a device main body, a reset button and a seed tube. The device comprises a main body and is characterized in that the main body sequentially comprises a cylinder, a partition plate, an arc-shaped baffle plate and a seed outlet from top to bottom, the partition plate is fixedly connected with the bottom ends of springs of a seed tube and a reset button, the seed tube penetrates through the partition plate, a buckle cover is installed at the bottom end opening of the seed outlet, the seed tube is placed at the seed outlet, and a clamping groove matched with the protruding part is formed in the wall of the cylinder.

Preferably, the reset button is sleeved inside the cylinder, and the bottom end of a spring of the reset button is fixedly connected to the middle of the partition plate.

Preferably, a plurality of clamping grooves are uniformly distributed on the surface of the cylinder.

Preferably, a plurality of pipe orifices are uniformly distributed on the upper surface of the shell, the positions of the pipe orifices correspond to the pipes, and the pipe orifices are provided with buckle covers.

Preferably, the bottom ports of the tubes are all provided with a buckle cover.

Preferably, a plurality of side openings are symmetrically distributed on the side surface of the shell, and the positions of the side openings correspond to the clamping grooves.

Preferably, the shell, the device body, the reset button and the tube are detachably connected.

Compared with the prior art, the invention has the beneficial effects that: each seed can be stored in the seed tube, the seed tubes can be prevented from being assembled and disassembled for many times during seed changing, and the operation steps required by the seeder during breeding of various seeds are greatly reduced.
