Problems solved by technology
With the long-term use of the reservoir, weeds often grow out of the reserved holes. Since the diameter of the reserved holes is only 10 cm, ordinary weeding tools can only cut off the top, and cannot completely clean the weeds from the roots. Clean, resulting in repeated cleaning after a period of time, a waste of manpower and financial resources, and if the slope protection of the reservoir is steep, it is easy to increase the possibility of staff drowning

Embodiment Construction
[0015] Such as figure 1 As shown, one end of the slope protection reserved hole weeding tool operating rod 1 is provided with a laterally extending blade 3, and the other end is provided with a handle 2. When in use, the end of the operating rod 1 with the blade 3 is inserted into the reserved hole, and the blade is passed through the blade. 3 Clear the weeds in the reserved hole, and the handle 2 is convenient for holding and operating. The operating rod 1 between the blade 3 and the limit block 4 is provided with a shaft sleeve 5, and the shaft sleeve 5 is provided with a bracket 6 for supporting the tool outside the reserved hole. The limit block 4 can limit the shaft sleeve 5 and the bracket 6 On the stroke of the operating rod 1, the bracket 6 is trumpet-shaped. When the end of the operating rod 1 with the blade 3 extends into the reserved hole, the bracket 6 supports the tool outside the reserved hole to prevent the tool from tilting when mowing. 3 scratch the inner wal...

The invention discloses a weeding tool for reserved holes for slope protection. One end of the operating rod of the tool is provided with a blade extending laterally, and the other end is provided with a handle. The operating rod is provided with a limiting block, and the blade and the limiting A shaft sleeve is provided on the operating rod between the bit blocks, and a bracket is provided on the shaft sleeve to support the tool outside the reserved hole. In the actual use of the invention, the operation is labor-saving and easy to carry, which solves the problem of weed regeneration caused by chopping the root system of weeds in the past, reduces the number of times of weed removal, and at the same time, the tool will not damage the hydraulic structure of the lower layer of the reverse filter bag. Work efficiency is at least double that of other commonly used tools.
Description
technical field [0001] The invention relates to the field of weeding equipment, in particular to a tool for removing weeds in reserved holes for concrete slope protection of reservoirs. Background technique [0002] Concrete block slope protection is often used in reservoir slope protection treatment, and a reserved hole is arranged between two prefabricated concrete blocks, and a reverse filter bag is plugged in the reserved hole. With the long-term use of the reservoir, weeds often grow out of the reserved holes. Since the diameter of the reserved holes is only 10 cm, ordinary weeding tools can only cut off the top, and cannot completely clean the weeds from the roots. Clean, resulting in repeated cleaning at intervals, a waste of manpower and financial resources, and if the slope protection of the reservoir is steep, it is easy to increase the possibility of staff drowning. Contents of the invention [0003] The technical problem to be solved by the present invention i...
