[0012] Compared with the related art, a device for adjusting the spraying density of flower and grass seeds provided by the present invention has the following beneficial effects:

[0013] The present invention provides a device for adjusting the spraying density of flower and grass seeds. By adding a valve plate inside the handle pipe, adding a central axis to the handle pipe, adding a hand lever to the central axis and other structures, when it is necessary to adjust the planting density, the valve plate can be driven to rotate through the central axis. During the rotation of the valve plate, the flow area inside the handle pipe can be adjusted. When the area is small, the flow rate of the grass seeds can be reduced, and thus the planting density can be reduced. On the contrary, the planting density can be increased, so that the planting seal of the device can be more easily adjusted.

[0014] The present invention provides a device for adjusting the spraying density of flower and grass seeds. By adding a spraying pipe to the T-shaped pipe, adding a threaded frame outside the spraying pipe, adding a positive and negative screw to the T-shaped pipe and other structures, during the use process, the two spraying pipes can work simultaneously to spray grass seeds inside the two planting areas, so that the planting efficiency can be effectively improved. And the spraying pipe can be driven to move through the threaded fit between the positive and negative screw and the threaded frame. During the movement of the spraying pipe, the planting width between the two spraying pipes can be adjusted, making the device more practical. BRIEF DESCRIPTION OF THE DRAWINGS
