Soil timing sampling device for balanced fertilization of vegetables

The utility model relates to the technical field of vegetable fertilization, in particular to a soil timing sampling device for balanced fertilization of vegetables, which comprises a cultivation frame, a soil main body is arranged inside the bottom end of the cultivation frame, and a device main body is fixedly connected to the surface of the inner wall of the cultivation frame. The device is provided with a lifting mechanism and a collecting mechanism, the lifting mechanism is favorable for driving a connecting block to move up and down on the surface of a screw rod when sampling is needed, and when the connecting block moves up and down on the surface of the screw rod, the collecting mechanism is driven by a connecting plate to move up and down in a device main body; the collecting mechanism is beneficial for driving a collecting block to transversely move through a fixing block when the collecting mechanism extends out of the cultivation frame for sampling downwards, the collecting block is in contact wit
