[0014] Compared with the prior art, the quantitative sowing device of the present utility model has the following beneficial effects:

[0015] 1. The setting of the moving frame is beneficial for the outer ends of the wheel axle and the driving disc to be connected by a synchronous belt. When the device moves, the driving disc is driven to rotate by the synchronous belt. The connecting shaft at the front end of the driving disc is slidably installed on the connecting groove at the top of the sowing pipe, and the guiding block at the outer end of the sowing pipe is slidably installed on the guiding groove of the base, so as to drive the sowing pipe to move up and down reciprocally, and insert the bottom of the sowing pipe into the sowing pit.

When the sowing pipe is at the upper end, the seeds in the seed bin automatically and quantitatively fall into the inner guiding groove in the moving frame through the seed outlet groove. When the sowing pipe moves downward, under the supporting action of the third elastic member, the moving frame moves downward and the first elastic member is compressed to block the seed outlet groove. After the moving frame moves to the lower end, the sowing pipe continues to move downward and the third elastic member is compressed. When the docking groove opening at the top of the sowing pipe communicates with the right end of the inner guiding groove on the moving frame, the seeds in the inner guiding groove automatically and quantitatively fall into the sowing pipe for pre-storage and sowing. This makes the device have better linkage, and automatically and quantitatively discharges seeds for sowing during the movement of the device, so that the device has better practicability.

[0016] 2. The plug is arranged such that it is slidably mounted on the sliding hole of the support plate through the connecting rod at the bottom. When the driving disc drives the seeding tube to move downward, the pressing plate contacts the bottom of the seeding pit. As the seeding tube continues to move downward, the second elastic member on the connecting rod is compressed, and the plug moves upward in the discharge tube. In cooperation with the conical structure at the top of the plug, the seeds in the seeding tube can automatically fall for seeding, effectively improving the seeding efficiency of the device.
