CN202354075U - Cutting knife crank for semi-feed reaping machine - Google Patents

Abstract

The utility model relates to a cutting knife crank for a semi-feed reaping machine. The cutting knife crank comprises a shaft and a roller wheel, wherein the shaft and the roller wheel are integrally cast into an integrated cutting knife crank. The cutting knife crank is simple in structure and low in production cost, and can be used for avoiding the problem that the shaft and the roller wheel are required to adapt to each other because the shaft and the roller wheel are integrally cast, so that the processing difficulty is reduced; and the problem that the shaft and the roller wheel perform mutual friction in the using process to cause abrasion is avoided, the contact area of the cutting knife crank and the cutting knife and fork of the reaping machine is only one third circumference of the roller wheel, and the cutting knife crank can be reused only by rotating the contact area of the roller and the knife and fork under a condition that the cutting knife crank is abraded. Therefore, the service life of the cutting knife crank is prolonged, and the production cost is reduced.

Description

Half-feeding harvester cutter crank

Technical field

The utility model relates to a kind of half-feeding harvester cutter crank.

Background technology

Grain header cutter crank comprises axle and roller, and axle and roller are adaptive each other, and difficulty of processing is higher; This cutter crank is arranged on grain header cutter transmission position and contacts with the cutter knife and fork; In motion process, axle can mutual friction mutually with roller, the while roller also can with the knife and fork friction; The rate of wear is fast, and service life is short.

The utility model content

The utility model for overcome the above problems provide a kind of simple in structure, production cost is low, the half-feeding harvester cutter crank of long service life.

The technical scheme of the utility model is: comprise axle and roller, described axle and the as a whole cutter crank of roller monoblock cast.

The utility model is simple in structure, production cost is low; With axle and roller monoblock cast, avoided axle and roller to need adaptive problem each other, reduced difficulty of processing; Also avoided simultaneously axle and roller in use mutually mutual friction cause wear problems; The utility model has only 1/3rd peripheries of roller at the contact-making surface with grain header cutter knife and fork, under the situation that wearing and tearing occur, as long as the contact-making surface of rotation roller and knife and fork can reuse; Prolong the service life of the utility model, reduced production cost.
