Detailed Description
As shown in fig. 2-6, the three-section lower frame of the novel wheel excavator of the present invention comprises a frame body 10, wherein the frame body 10 comprises a front section frame body 15, a middle section frame body 16 and a rear section frame body 17 which are connected in sequence. One end of the front section frame body 15, which is far away from the middle section frame body 16, is provided with a bulldozer connecting hole 13 and a front axle mounting hole 14 which are perpendicular to each other, and the end part of one end, which is close to the middle section frame body 16, is opened. The rear frame body 17 is provided with a rear bridge connection plane 12 at both sides of one end far away from the middle frame body 16, and the end part close to one end of the middle frame body 16 is open. Middle section support body 16 middle part be equipped with ring flange 11, both ends are equipped with the reinforcing plate 20 that extends into the open tip of anterior segment support body 15 and back end support body 17 respectively.
