Description

Technical Field

[0001] This invention relates to the field of residual film recycling equipment, and in particular to a strip rake-type pre-planting surface film recycling machine. Background Technology

[0002] Mulching technology has the effects of warming, moisture retention, and drought resistance, which can effectively increase crop yield. The use of a large amount of residual mulch in farmland has increased farmers' economic benefits, but the mulch residue left in farmland has an impact on the ecological environment.

[0003] Currently, mechanized recycling has become an effective means of solving the problem of residual film pollution. Existing residual film recycling machinery is classified according to the operation time into seedling residual film recycling machines, pre-sowing residual film recycling machines, and post-plowing residual film recycling machines. Among them, pre-sowing residual film recycling is completed after farmers harrow the land and before weeding, aiming to clean up the residual film used in the previous growth cycle. If the residual film is not effectively treated, it will seriously threaten the emergence and growth of crops. However, the distribution of pre-sowing residual film is irregular and highly fragmented, which makes it difficult for traditional film rakes to harvest. The pre-sowing residual film recycling rate is not high, and the uneven ground caused by the operation of pre-sowing residual film recycling machines requires a separate harrowing machine to level the ground to restore the sowing environment, increasing the number of machine operations.

[0004] In view of this, we propose a strip rake-type pre-sowing surface film breakage recovery machine to solve the problem of difficulty in recovering pre-sowing film breakage by current film rake machines. Summary of the Invention
