Abstract
The utility model relates to a guard without a stationary knife relates to agricultural machinery, in particularly to a combined harvester header, is also an improvement of the existing guard, and mainly comprises a guard beam assembling plane, an assembling hole, a power knife delivery groove, a protective tongue and an edge plane. Two assembling holes are arranged on the guard beam assembling plane. The power knife delivery groove is arranged between the assembling hole and the guard. The back of the knife delivery groove is provided with the protective tongue, under which the edge plane is arranged. The utility model has simple production and good toughness, when working, a self-grinding knife is formed by the reciprocating movement between a movable knife and the guard, and the utility model has strong shearing force for the crops as the edge is sharpened by the more grinding, can effectively avoids the mechanical errors of a guard provided a stationary knife caused by loosening of rivets, and avoids the phenomenon of spike loss and spike pulling in the field operation of the harvester, thus reducing the loss ratio of the grain.
Description
Technical field: the utility model relates to the particularly a kind of no stationary knife guard of combine harvester cutting table of agricultural machinery, also is the improvement to existing guard.
Background technology: guard is a key components and parts at combine harvester cutting table position, and the cutting performance of crops is good and bad, and the receipts of grain are clean, and the performance of Loss Rate and guard and quality have direct concern.At present, existing guard is to be formed by the roll-forging process manufacturing.Its manufacturing process complexity, also often loosing of rivet causes mechanical breakdown when gathering in the field, makes troubles to harvesting, wastes the harvesting time.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of and oozes after the no stationary knife guard that selective hardening is made has solved the mechanical breakdown that guard causes because of loosing of rivet in the field harvesting with the casting of malleable casting alloy.Technical scheme of the present invention be achieved in that no stationary knife guard by: installing hole, guard Beam installed surface, power tool slot, protect tongue, the sword face is formed.Be provided with two installing holes on guard Beam installed surface, the centre of installing hole and guard is provided with the power tool slot, is provided with in the back of tool slot and protects tongue, and protecting the hypogloeeis face has light face sword face.This product manufacturing is simple, moves reciprocatingly between moving knife and the guard during work, forms from sharpening; The cutting edge place grinds sharper and sharper, shearing force to crops is strong, can effectively avoid the mechanical breakdown that causes because of loosing of rivet with the stationary knife guard, and grain header can be avoided losing fringe, pulling out the fringe phenomenon when farm work, reduce the Loss Rate of grain, product has toughness preferably.
