Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the tractor comprises a tractor chassis 1, a connecting block 2, a spring 3, a hydraulic telescopic mechanism 4, a driving motor 5, a sealing box 6, a polygonal wheel 7, a piston block 8, a piston rod 9, a conduit 10 and a clamping block 11.

An anti-trap structure for a tractor, an embodiment of which is shown in figure 1. Including two connecting blocks 2 that can dismantle the connection with tractor chassis 1, the embodiment is shown in fig. 4, 2 accessible threaded connection of connecting block lock with tractor chassis 1, be convenient for install connecting block 2 on tractor chassis 1, be convenient for pull down connecting block 2 simultaneously, 2 bottom rigid couplings of connecting block have

pressure spring

3, 3 bottom rigid couplings of pressure spring have the supporting shoe, pressure spring 3 can improve the tractor and break away from the shock attenuation effect when sunken, supporting shoe lower surface rigid coupling has hydraulic telescoping mechanism 4.

The embodiment is shown in fig. 2, and hydraulic stretching includes first hydraulic pressure chamber, and sliding connection has piston block 8 in the first hydraulic pressure chamber, and piston block 8 is inside to be equipped with the second hydraulic pressure chamber, and sliding connection has piston rod 9 in the second hydraulic pressure chamber, and piston rod 9 free end stretches out first hydraulic pressure chamber and second hydraulic pressure chamber and rigid coupling has seal box 6, and the rigid coupling has driving motor 5 in the seal box 6, and driving motor 5's output shaft rigid coupling has polygon wheel 7, and the embodiment is shown in fig. 3, the utility model discloses in adopt the hexagon wheel, the hexagon wheel is difficult for skidding, makes the tractor break away from sunken ground more easily.
