[0002] Land preparation equipment for forestry planting, especially the traditional shovel, is an indispensable basic tool in forestry planting operations. The main function of the shovel is to turn over, loosen the soil, remove weeds, and dig ditches to provide a suitable growing environment for subsequent planting work. Its design typically includes a wide, flat blade for cutting and turning the soil; a long handle to facilitate the operator in applying force and controlling the digging depth and angle; and a sturdy neck connecting the blade and handle to ensure the stability and durability of the overall structure.
[0003] With the expansion of forestry planting and the increasing complexity of working environments, traditional shovels are proving inadequate in certain aspects. Especially when performing land preparation work outdoors, operators often struggle to see clearly at night or in dimly lit environments, leading to errors and inefficiency. To overcome this problem, operators often need to carry additional lighting equipment, such as flashlights or headlamps. This not only increases the complexity of the work but also makes it easier for insufficient lighting or light interference to affect accuracy and safety. Utility Model Content

[0032] In summary, when this forestry planting land preparation device needs to be used in a dimly lit environment, the frame 14 can be twisted to rotate the threaded disc 17 inside the receiving hole 19 until the threaded disc 17 is completely disengaged from the top rod 8, making it easy to disassemble the lighting lamp 18. Then, the lighting lamp 18 is placed on one side of the hollow handle 3, and the hollow handle 3 is positioned between the two pressure plates 13. Then, the double-acting screw 15 is twisted to drive the two pressure plates 13 to move towards each other until the locking pin 16 is inserted into the locking hole 21. After that, the lighting lamp 18 can be installed on one side of the hollow handle 3. The lighting lamp 18 can be used to illuminate one side of the shovel body 1. Side lighting is provided to prevent insufficient lighting or light interference from affecting the accuracy and safety of the operation. After the lighting lamp 18 is installed, it can be removed from the hollow handle 3 and then installed into the top rod 8 for storage, so as to facilitate carrying the lighting lamp 18. Pulling down the pull ring 11 will cause the locking pin 12 to move out of the locking hole 20, which can release the lock between the locking plate 7 and the positioning plate 9. Then, twisting the top rod 8 will cause the threaded column 5 to rotate inside the threaded sleeve 4. Through the thread transmission, the threaded column 5 can be moved out of the threaded sleeve 4.
