Two hanging plates are fixed on both sides of the lifting frame, the rotating shaft is arranged between the two hanging plates, the oil cylinder connecting piece is installed on the rotating shaft and connected to the rotating oil cylinder, and the push rod of the rotating oil cylinder is movably connected to the connecting plate.

[0008] The yam digging device according to the claim is characterized in that: the left and right adjustment mechanism comprises a fixing plate, a sliding rod, a left and right adjustment oil cylinder and a push plate. Two fixing plates are fixed at the front ends of the lifting frames at both ends. Both ends of the sliding rod are connected to two connecting plates. The left and right adjustment oil cylinder is installed on the sliding rod. Both sides of the left and right adjustment oil cylinder are connected to two push plates. The push plates are provided with clamping grooves up and down. The upper clamping groove of the push plate is clamped into the rotating shaft, and the lower clamping groove of the push plate is clamped into the first connecting shaft.

[0009] Preferably, an oil cylinder connecting plate is fixed at the top of the lifting frame. Both ends of the oil cylinder connecting plate are connected to the top output rods of two lifting oil cylinders. The two lifting oil cylinders are arranged on both sides of the main frame.

[0010] Preferably, the earth-pushing mechanism comprises an oil cylinder fixing plate, an earth-pushing oil cylinder, a guide sleeve, a guide pipe and an earth-pushing plate. The oil cylinder fixing plate and two guide sleeves are fixed on the main frame. The earth-pushing oil cylinder is fixed on the oil cylinder fixing plate. Two guide pipes respectively pass through the two guide sleeves. The output end of the earth-pushing oil cylinder and one ends of the two guide pipes are both connected to the earth-pushing plate.

[0012] Preferably, the lifting frame is a lifting pulley frame, and a plurality of pulleys and sliding bearings are arranged on both sides of the lifting frame.

[0013] Working principle: The lifting frame drives the digging shovel to move up and down, so that the digging shovel completes the action of shoveling into the soil. The digging power pushes the connecting plate, driving the digging shovel to complete the action of digging the soil. The harder the soil quality, the greater the difficulty of digging, and the greater the power required by the digging power. In order to operate in soils with different hardnesses, the present invention designs a soil cutting and pulling mechanism, a cutting and pulling power, a guide wheel device and a wire. The cutting and pulling power is fixed on the top of the main frame. The guide wheel device is fixed at the front end of the horizontal part of the main frame. One end of the wire is connected to the cutting and pulling power, and the other end is connected to the front end of the digging shovel through the guide wheel device; when the lifting frame rises, the digging shovel remains vertically downward, and at this time the wire is lengthened; following the action of the digging shovel, it enters the soil downward. Before the digging action, the wire is tightened. With the tightening action, the wire will cut the soil on the path, reducing the load of the digging action of the digging shovel and making it easier for the digging shovel to shovel up the soil; and during the digging action, the wire continues to be tightened, providing a pulling force for the digging shovel and cooperating with the digging power to complete the digging action. After the digging action is completed, the digging shovel is in a horizontal state. At this time, the soil-pushing mechanism pushes the soil on the digging shovel to one side, facilitating the removal of the yam in the soil. The towing vehicle moves forward. According to the movement of the vehicle, the left and right adjustment mechanism is finely adjusted to align the digging shovel with the marked digging line. The lifting frame is raised, the wire is lengthened, and the digging shovel is adjusted to be vertically downward. The actions of shoveling and digging are repeated again.

[0014] The beneficial effects of the present invention are:

[0015] 1. This device can operate on hard soil, with stronger applicability.

[0016] 2. By setting up the soil cutting and pulling device, this device makes it easier to lift the digging shovel.

[0017] 3. The left - right adjustment mechanism is added, eliminating the need for a towing vehicle to adjust the position, and reducing the over - compaction of the soil caused by the adjustment of the towing vehicle's direction.

[0018] 4. The yam digging speed and the yam integrity rate are improved. BRIEF DESCRIPTION OF THE DRAWINGS
