Switchable cutting piece matched with harvester blade protecting machine

Abstract

The invention provides a switchable cutting piece matched with a harvester blade protecting machine. The switchable cutting piece comprises a switchable cutting piece assembly, and the switchable cutting piece assembly does not comprise a blade protecting machine and is provided with notches, so that waste blockage can be cleaned automatically. The switchable cutting piece assembly comprises a cutting bucket steel plate and a plurality of cutting piece bottom frames which are arranged on the cutting bucket steel plate and are closely connected; each cutting piece bottom frame comprises a triangular part A and a groove frame which is integrally arranged with the triangular part A; each of the groove frames and one corresponding cutting piece bottom frame form an L shape; each two adjacent cutting piece bottom frames are fixed by a transversal rod, so that a new blade protecting machine is formed; each cutting piece bottom frame is provided with a cutting piece component; each cutting piece component comprises a cutting blade part and a mounting part arranged at the rear end of the corresponding cutting blade part; each mounting part comprises a groove; and each groove is fixed on the corresponding groove frame. The switchable cutting piece disclosed by the invention has the main advantages that a mounting face C and the cutting piece bottom frames can be fixed at the cutting bucket steel plate together by screws. The new blade protecting machine can also be directly welded on the cutting bucket steel plate.

Description

technical field [0001] The invention relates to a harvester blade technology, in particular to a paired switchable blade guard of a harvester. Background technique [0002] Harvester harvesting edge guards, whether it is single claw, double claw, three claw or other shapes, their task is to harvest cutting pieces such as vegetation. Its operating principle is that the cutting blade is in balanced contact on the surface of the edge guard and the cutting knife is moved left and right by the rocker arm to complete the cutting task. [0003] After a period of friction between the cutting blade and the surface of the edge guard during operation, the cutting blade and the edge guard will be worn, and the cutting task will be affected when the wear reaches a certain level, so it must be replaced. Install a brand new cutting blade and blade guard. The replacement of the cutting blade is only a blade, but the blade guard is a whole casting. Because the surface is worn to a certain e...

Problems solved by technology

[0003] After a period of friction between the cutting blade and the surface of the edge guard during operation, the cutting blade and the edge guard will be worn, and the cutting task will be affected when the wear reaches a certain level, so it must be replaced. Install a brand new cutting blade and blade guard. The replacement of the cutting blade is only a blade, but the blade guard is a whole casting. Because the surface is worn to a certain extent, the entire casting has to be discarded and replaced with a new blade guard. , which not only wastes a lot of resources, but also takes time to replace the assembly work
