A discharge gate, discharge gate are connected with seed spout, and the discharge gate is equipped with lid, and lid is flexibly connected with plants case；In the rack
Driving motor is installed, driving motor is connected with cylindrical cam, and the end face of cylindrical cam is equipped with curved profile, cylindrical cam with
Driving motor coaxial line, the cylindrical cam are connected with several driven members, and driven member and discharge gate correspond, driven member with
Housing slide connection, driven member are connect by connecting rod with lid；Driven member and/or lid are equipped with spring, and the spring is mounted on
Rack perhaps in plants case spring for resetting driven member or lid.
Preferably, the plants case includes conical section, the equally distributed conical section of several discharge gates it is same
On circumference.
Preferably, the lid is slidably connected with plants case, and described connecting rod one end and driven member be hinged, the other end and lid connect
It connects.
Another preferred, the lid and plants case are hinged, described connecting rod one end and driven member hingedly, the other end and lid
Hingedly.
Preferably, the driven member is roller follower.
Preferably, the driving motor is frequency control motor.
By adopting the above technical scheme, due to the setting of cylindrical cam, driven member, connecting rod, so that being movably connected in plants case
Lid can achieve the purpose that continuous seeding with the motion state periodicity open and close of driven member；The setting of spring simultaneously,
So that driven member and/or lid have the function of replying state, lid period in the case where opening and closing two states is further determined that
Property switching.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1- rack, 2- plants case, 3- discharge gate, 4- seed spout, 5- lid, 6- driving motor, 7- cylindrical cam, 8-
Curved profile, 9- driven member, 10- connecting rod, 11- spring.
Specific embodiment
