Research and experiment on the trenching performance of orchard trenching device

Theoretical analysis of trenching performance

Structure and working principle of trenching device

The trenching device (as shown in Fig. 1a) is mainly composed of a cutter head, a trenching cutter, a traction frame, a cross beam, a draft cover assembly, a cutter head driving mechanism and a longitudinal beam. The cutter head assembly comprises a trenching cutter A and a trenching cutter B, which were arranged in sequence by subsection spiral (A-B-A-B-…, each of A and B were divided into one group, 7 groups altogether, one group of cutting tools met the requirements of furrow agriculture…
