Comb tooth rotating bevel gear speed increase transmission mechanism and comb tooth imitation depth adjustment device group; front and rear shaft drive bevel gear speed transmission mechanism directly driven by bearing seat support ground wheel directly driven by bearing seat below the frame on both sides of the frame, front and rear comb tooth axial centerline is located at the longitudinal operation directly above the double seedling eye or single seedling eye of the small wall, each can be configured with 6 to 10 groups; the left and right single-wing hoeing shovel and the comb tooth are arranged on the front cross beam; the weeder that adopts this structure improves the efficiency by 8 to 10 times compared with manual hoeing, the seedling injury rate is low, and the seedling removal cleaning rate is average.
The foam filter is cleaned every 25 hours, and dust should be more frequent.
The cleaning of the foam filter element is cleaned with kerosene or washing liquid and clean water, squeezed and dried.
