Overload spring 17, which is pressurized, to be shunk；The front end face of the cant beam 4 is contacted with the bending part of 2 lower end of postive stop baffle, makes skinning shovel board 7
With certain angle of penetration.
The course of work of the utility model is as follows：
The utility model incomplete film-recovering machine spring antioverloading loosening shovel is mounted on the front of incomplete film-recovering machine, as residual film is returned
Receipts machine is advanced forward operation, and skinning shovel board 7 is loosened the soil with certain angle of penetration skinning that buries.After loosening shovel buries, pass through analysis
Soil is to the active force of shovel, the resistance after the horizontal direction that loosening shovel is mainly given by soil.Due to 4 its own gravity of cant beam,
Connecting rod 9 is set to be pressurized by the horizontal forward pulling force that divides, connecting rod 9 and then pulling rolling bearing 11, preceding antioverloading spring 17, generation pushes away
Dynamic rolling bearing 11 has the elastic force of tendency toward sliding backward, and the resistance after the horizontal direction that is subject to of loosening shovel, and two power resultant force is common to be made
Divide pulling force with counteracting part and plays the role of bumper and absorbing shock.When loosening shovel works in the state of stress balance, such as without impinging on
Barrier, loosening shovel can be always maintained at the work status.
Skinning shovel board 7 is walked in the soil when encountering the barriers such as stone, and loosening shovel is turned by larger mutation impact force
Dynamic beam 4 quickly can backward lift under the elastic force synergy of mutation impact force and preceding antioverloading spring 17, and skinning shovel board 7 then can
Across barrier, when cant beam 4 lifts, for connecting rod 9 by the partial pressure after horizontal direction, rolling bearing 11 can press against rear spring activity
It plate 15 and is quickly moved backward along bearing track 14, rear defence overload spring 13 is pressurized, and before generating rolling bearing 11 being pushed to have
The elastic force of tendency toward sliding, offsets a part of partial pressure, and rear defence overload spring 13 plays the role of bumper and absorbing shock.When across barrier
Afterwards, skinning shovel board 7 can quickly be fallen after rise under the elastic force synergy of its own gravity and rear defence overload spring 13, connecting rod 9 by
Preceding divides pulling force, rolling bearing 11 that can then press against preceding spring movable plate 16 and quickly move forward, and preceding antioverloading spring 17 is pressurized, production
The raw elastic force for pushing rolling bearing 11 to have tendency toward sliding backward, and offset a part and divide pulling force, play the role of bumper and absorbing shock.
