Abstract
The utility model discloses a leveling supporting plate mechanism. The leveling supporting plate mechanism comprises a fixed seat and a supporting plate which is rotatably arranged on the fixed seat, wherein a pressure adjusting device is further arranged between the lower end of the supporting plate and the fixed seat; the pressure adjusting device comprises a hanging rod and a hanging rod rotary sleeve; one end of the hanging rod rotary sleeve is fixedly connected with the fixed seat and the other end of the hanging rod rotary sleeve is connected with the middle part of the hanging rod; the hanging rod is provided with an upper spring and a lower spring; the upper spring is arranged at the upper end of the hanging rod rotary sleeve and the lower spring is arranged at the lower end of the hanging rod rotary sleeve; a plurality of adjusting holes are formed in the upper end of the hanging rod; gaskets are fixedly connected with the upper end of the upper spring and the lower end of the lower spring respectively; the gasket of the upper spring is arranged on the hanging rod by a positioning pin. Compared with the prior art, the pressure adjusting device of the supporting plate can adopt the two sprigs and pre-stress of the spring is adjusted at the upper end of the upper spring through the positioning pin so as to adjust the pressure acting on the supporting plate and realize the universality of an applicable land range of a tillage machine.
Description
Technical field
The utility model relates to agricultural machinery technological field, specifically a kind of leveling supporting plate mechanism for harvesting and tillage machine.
Background technology
The supporting plate mechanism of harvesting and tillage machine is mainly used in the smooth of soil, in the time cultivating because the depth and place difference of cultivating, can form below or high or low out-of-flatness soil, be convenient to pouring and other needs in later stage in order to make Land leveling, generally after farming machine, be all with a supporting plate mechanism, in smooth process, supporting plate mechanism requires to have certain pressure and can not be even at the cost of one's life, so the difficulty of design is higher.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of pressure adjustable leveling supporting plate mechanism.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of leveling supporting plate mechanism, comprise the supporting plate on holder that is arranged on of holder and rotation, between the lower end of described supporting plate and holder, be also provided with a pressure-regulating device, it is characterized in that: described pressure-regulating device comprises a suspension rod and a suspension rod pivoted housing, described suspension rod pivoted housing one end and described holder are fixed, the other end of suspension rod pivoted housing is connected with the middle part of described suspension rod, on described suspension rod, be provided with upper spring and lower spring, described upper spring is arranged on the upper end of suspension rod pivoted housing, described lower spring is arranged on the lower end of suspension rod pivoted housing, also offer multiple adjustment holes in described suspension rod upper end, be fixedly connected with respectively packing ring in the upper end of upper spring and the lower end of lower spring, the packing ring of upper spring is arranged on described suspension rod by an alignment pin.
Described supporting plate is connected on described holder by a supporting plate pin.
Described pressure-regulating device is two and is arranged side by side on the width of described supporting plate.
Compared with prior art, the pressure-regulating device of the utility model supporting plate adopts two springs, and adjust the prestressing force of spring by alignment pin in the upper end of upper spring, thereby corrective action pressure on supporting plate has been realized harvesting and tillage machine and be suitable for the popularity of landholding.
