Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a tube box device with a scraper. Background Technology

[0002] Traditional underground pipe laying construction in saline-alkali land improvement generally requires excavation, support, subbase construction, pipe laying and backfilling. For example, the existing technology CN110593375A discloses a method for laying pipes by excavating trenches, which includes digging trenches by using a hydraulic backhoe excavator and manual excavation, using a crane to lift the pipe into the excavated trench, and using manual backfilling and light compaction equipment to compact the pipe to complete the pipe laying.

[0003] In existing technologies for improving saline-alkali land using trenching and pipe-laying machines, it is necessary to lay sand and gravel underground to create seepage channels, and then bury underground pipes within these channels. This allows excess saline water from the soil surface and surface layer to flow through the seepage channels into the underground pipes and eventually drain away. The sand and gravel laid over the underground pipes requires manual labor, resulting in high construction costs and slow construction speed. Utility Model Content
