FIELD: agricultural engineering. ^ SUBSTANCE: agrobridge has girder fixed on caterpillar carts movable on permanent tracks, agricultural machines, auxiliary power and processing equipment. Girder has transverse through openings having cross-section sizes exceeding those of large-sized agricultural machines used on agrobridge. Lower sides of girder openings are provided with detachable floors, side brackets fixed on girder sides, floors adapted for lengthening of opening floors, detachable frames with two pairs of loosely rotating rollers for fixing position of wheels of large-sized agricultural machines kinematically coupled to working units of agricultural machines. Frame with rollers may be attached to any part of floor. Frame has removable shields, accumulating hoppers and rods pivotally secured to girder and equipped with hooks and screw-type turnbuckles for attachment of large-sized agricultural machines in agrobridge openings. ^ EFFECT: reduced height of agrobridge allowing agricultural machines of different sizes to be employed for harvesting works. ^ 2 cl, 10 dwg |
