Design and experimental validation of improved grapevine burying machine

摘要

In order to address the low soil breaking rate, poor soil covering performance, and low working efficiency of the existing 3MT-1.8 and PMT-75 grapevine burying machines, two types of improved burying machines, namely the 3MTLJ-1.8 and 3MTXP-1.8, were developed in consideration of the local Ningxia soil conditions. Field experimental results indicated that the soil breaking rate of the 3MTLJ-1.8 machine was 71.44%, and its soil sampling volume increased by approximately 30% compared to that of the 3MT-1.8 machine. It was verified that the self-developed 3MTLJ-1.8 machine can be used in the southern regions of Ningxia. Furthermore, the soil sampling volume of the 3MTXP-1.8 burying machine was 0.24 m3/m, and its soil breaking rate increased by more than 41.42% compared to the standard required volume. The 3MTXP-1.8 machine can be used in the northern areas of Ningxia, where the soil hardness is higher. The results can provide a reference for the development and popularization of grapevine burying machines in Ningxia.
