Push-and-pull acceleration hydraulic system of horizontal directional drilling machine and horizontal directional drilling machine

The utility model discloses a push-and-pull acceleration hydraulic system of a horizontal directional drilling machine and the horizontal directional drilling machine. The push-and-pull acceleration hydraulic system comprises an oil tank, a main pump, an acceleration pump, a push-and-pull hand-operated valve connected with the main pump, a push-and-pull motor and a four-linkage multi-way hand-operated valve connected with the acceleration pump, wherein the main valve and the acceleration pump are connected with the oil tank. The four-linkage multi-way hand-operated valve and the push-and-pull hand-operated valve are connected with the push-and-pull motor. The improved push-and-pull acceleration hydraulic system of the horizontal directional drilling machine is adopted, when a drilling tool is mounted and demounted, pushing and pulling can be rapidly withdrawn, time is saved, and efficiency is improved. During drilling work at ordinary times, a handle of the push-and-pull hand-operated valve on the left side i
