CN2552316Y - Cutting knife driving mechanism for self-driving cutter-windrower - Google Patents

Abstract

A cutting mechanism of a self-propelled windrower pertains to a crop harvesting tool in the agricultural machinery. The cutting mechanism comprises an output shaft of a gear case, a crank, a connecting rod, a swing arm soldering, bearings, bushings and a rotating shaft of the swing arm, etc. The crank is mounted on the output shaft of the gear case. Two ends of the connecting rod are movably connected with the crank and the soldering part of the swing arm respectively. The rear end and the front end of the soldering part of the swing arm are coordinated with the hinge of the swing arm rotating shaft fixed on the rack and a cutting knife. The transmission mechanism has the advantages of simple structure, smooth transmission, small vibration, high operating reliability, less faults, and long service life.

Description

The cutter transmission mechanism of self-driving type swather

Technical field

The utility model belongs to the grain harvest facility in the agricultural machinery, is mainly used in rice wheat, herbage etc. and cuts the solarization operation.

Background technology

Cereal cuts that to shine the harvest operation mode be to adopt comparatively general agricultural method on the current agricultural, cuts and shines results for adapting to cereal, and its swather model, kind are more, but its basic structure is similar.In the cutter transmission system, because the transmission distance is longer, the drive mechanism complexity, facility vibrate greatly in driving cutter reciprocating motion process, and transmission is unreliable, and fault is many, and facility operating efficiency and service life are descended, and operating cost improves.

Summary of the invention

The purpose of this utility model is exactly the problem and shortage that exists at cutter transmission system in the prior art, design provides a kind of cutter transmission mechanism of novel self-driving type swather, reaches to simplify the cutter drive mechanism, facility vibration when alleviating operation, improve the purpose of operational reliability and operating efficiency, reduction fault rate and operating cost.

Basic design of the present utility model is, installing the crank by the slotted cheese head screw location on the transmission case output shaft, and locking steel wire is wrapped in the groove of slotted cheese head screw, and screw is locked; The two ends of connecting rod flexibly connect by bearing and crank with by self-aligning roller bearing and swing arm seam middle part respectively; The front end of swing arm seam is installed with axle sleeve, matches with cutter by this axle sleeve; The rear end of swing arm seam utilizes bearing and the swing arm rotating shaft that is fixed on the frame to be hinged, and constitutes the cutter transmission mechanism of self-driving type swather.

The utility model is simple in structure, and operation is steady, vibrates for a short time, has increased substantially the operational reliability and the operating efficiency of facility, has prolonged service life, and fault rate is low.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The cutter transmission mechanism of self-driving type swather comprises frame 6 and cutter 8, on the axle head of transmission case output shaft 1, install crank 12, slotted cheese head screw 2 is positioned at crank 12 on the transmission case output shaft 1, and locking steel wire 13 is wrapped in the groove of slotted cheese head screw 2 and is locked; The two ends of connecting rod 10 are flexibly connected with crank 12 with by self-aligning roller bearing 3 and swing arm seam 7 middle parts by bearing 11 respectively; The front end of swing arm seam 7 is installed with axle sleeve 9, and matches with cutter 8 by axle sleeve 9; The rear end of swing arm seam 7 utilizes bearing 4 and the swing arm rotating shaft 5 that is fixed on the frame 6 to be hinged.

During operation, transmission case output shaft 1 drives crank 12 rotations, makes connecting rod 10 come and go the seam 7 of pulling swing arm around swing arm rotating shaft 5 swings, and the axle sleeve 9 of its swing arm seam 7 front ends drives cutter about 8 and moves back and forth, and finishes the harvesting operation of cutting cane.
