Potato soil-crushing and digging device

The invention discloses a potato soil-crushing and digging device. The potato soil-crushing and digging device is characterized by being provided with a machine frame; a decelerator is fixedly connected onto the machine frame through a bolt; its front end is fixedly connected with a soil-crushing mechanism through a bearing; its bottom is fixedly connected with the digging shaft of a digging mechanism through a bearing; the left side is connected with an angle adjustor; the decelerator transmits power by a chain through a gear of a power shaft and a gear on the middle shaft of the soil-crushing mechanism, so that a soil-crushing roller of the soil-crushing mechanism is driven to actively rotate; both the soil-crushing mechanism and the digging mechanism can rotate corresponding to the machine frame; the adjustor is welded on the machine frame through an adjusting plate at the upper end; a connecting rod at the lower end is connected with the digging mechanism; the connecting rod is connected onto the adjustin
