Novel structure connecting protective guard and crossbeams of tractor

The utility model discloses a novel structure connecting a protective guard and crossbeams of a tractor, which comprises the protective guard and the crossbeams. The structure is characterized by further comprising two support plates and channel sections. The two support plates which are both U-shaped bending pieces are symmetrically equipped between the protective guard and the crossbeams. One upper parallel side of each support plate is welded on the lower part of the protective guard while one lower parallel side of each support plate is respectively in contact with the upper part of one crossbeam. The channel sections arranged in an inclined way simultaneously contact the crossbeams and the support plates. Bolts are screwed by double nuts after passing through the support plates and the channel sections. A wedge-form clamping way is adopted in the utility model to support and fix the protective guard on the crossbeams of the tractor. The fixation process which is not limited by the positions of holes on the side surfaces of the crossbeams further requires no punching on the upper planes of the crossbeams. The bolts and the nuts are applied for direct fixation. The connecting structure in the utility model has the advantages of simple production, convenient operation and easy installation. Meanwhile, the connecting structure poses no damage to the crossbeams of an original chassis and casts no influence on the overall strength of the crossbeams. Therefore, the connecting structure further has the advantages of safety, reliability and strong universality.
