During the ditching process in farmland, hard objects such as stones are often encountered, which can easily damage the cutting heads 21 and the plows 24. The setting of the stone shovel 3 effectively solves this problem, protects the ditching components and reduces the frequency of maintenance and replacement.

[0034] Working principle: The single-cylinder diesel engine 9 serves as the power source. Its output power is transmitted to the bevel gear 27 via the drive shaft 15, coupling 16, connecting rod 17, and coupling 18. The bevel gear 27 meshes with the bevel gear 28, driving the rotating shaft 26 to rotate, thereby driving the trenching mechanism. During trenching, the cutter head 21 on the cutter disc 20 rotates and cuts into the soil, while the plow blade 24 on the fixed frame 23 moves forward with the machine to assist in turning the soil. The two work together to achieve trenching. The auxiliary wheel 25 helps control the trenching depth. The stone fork 3 handles stones to prevent damage to the cutter head 21 and plow blade 24. The electric push rod 14 extends and retracts, and through its connection with the hinge block 4, hinge block 22, and hinge block 29, it drives the bracket 28 to rotate around the rotating shaft 12, changing its height and thus adjusting the trenching depth. At the same time, the mudguard 6 blocks the mud splashed during trenching, and the wheels 2 support the vehicle body 1 and assist its movement.
