A soil shovel plug tray crop harvester includes a walking device, an excavating device pivoted on the walking device and used for digging a plug tray, a conveying device, and a separating device. The conveying device includes a grid-like chain rotatably disposed in the excavating device. The grid-like chain has several link rods, and each two adjacent link rods define a chain distance suitable for embedding the number of cup cups of the plug tray, and drive the plug tray to move. The separating device includes at least one clamping unit. The at least one clamping unit has an entrance adjacent to the grid-like chain, and a channel connecting the entrance and gradually increasing the distance from the grid-like chain along the axis direction, the entrance is suitable for entering crops on the plug tray So that the crop is displaced in the direction of the channel and perpendicular to the grid-like chain following the channel until it is pulled up and separated from the plug tray. In this way, the crop is separated from the plug tray by embedding the cup and pulling up the crop, thereby maintaining the integrity of the crop and improving the convenience during harvesting.一種鏟土式穴盤作物收穫機，包括一行走裝置、樞設在該行走裝置且用於挖掘一穴盤的一挖掘裝置、一輸送裝置，及一分離裝置。該輸送裝置包括可轉動地設置在該挖掘裝置的一柵狀鏈條。該柵狀鏈條具有數鏈桿，每二個相鄰的鏈桿界定出適用於供該穴盤之數穴杯嵌入的一鏈距，並帶動該穴盤移動。該分離裝置包括至少一夾持單元。該至少一夾持單元具有鄰近該柵狀鏈條的一入口，及連接該入口且沿該軸線方向逐漸擴大與該柵狀鏈條之間距的一通道，該入口適用於供該穴盤上的作物進入，使作物依循該通道而朝同向於該通道且垂直於該柵狀鏈條的方向位移，至被拔起且與該穴盤分離。藉此，以嵌入穴杯及拔起作物的方式，使作物與穴盤分離，進而維持作物的完整性，及提升採收時的方便性。
