Abstract
The utility model provides a collision-proof vibration-damping undercutting device for combine harvester, comprising an undercutting cutter set, a cutter frame, a sliding sledge positioned on the bottom surface in the front middle part of the cutter frame, a pipe shaft connecting the back parts of two edge beams of the cutter frame, a crank connecting rod mechanism connected with the undercutting cutter set, a crank-link driving shaft arranged in the pipe shaft through a bearing, and a sliding groove draw rod connecting the upper cutting table and the cutter frame. The device is characterized in that the position included angle between the two edge beams of the cutter frame and the flat surface is not bigger than 30 degree, the pipe shaft is fixed on the chassis of the machine frame, the back end parts of the two edge beams of the cutter frame are connected with the pipe shaft through a hooping structure, and a moving gap is reserved between the hoop and the pipe shaft. In working, when the sliding sledge collides with the ridges of the field, the cutter frame of the utility model can automatically lift up, so as to effectively avoid the damage of the cutting knife when inserting into the ridges. Simultaneously, the vibration of the cutter frame is reduced, which greatly improves the working safety and the working efficiency of the complete machine.
Description
Technical field
The utility model relates to a kind of cutter sweep down of all feeding-in combine.
Background technology
Existing many all feeding-in combines are provided with double-deck cutter sweep, its upper strata cutter are cut the ear-cut part straw, lower floor's cutter cutting straw root, after the cutting, following straw portion promptly lodges on the ground, only top band fringe short straw enters the sheller unit of combine, thereby has alleviated the load of sheller unit greatly, has increased substantially the harvesting efficiency of combine.But also there are some shortcomings in existing double-deck cutter sweep, as: installation angle α of knife rest two side bars of cutter sweep and ground level is bigger than normal under it, generally reach 45 °, thereby work as grain header at work, when the skid of its lower slide bottom collides ridge, the component deficiency that it makes progress is so that the automatic lifting of knife rest, and causes cutter to insert in the ridge and damage; Fixedly connected with tubular axis because of knife rest two side bar rearward end in addition, and tubular axis is rotatably installed on the rack chassis, during the running of the power transmission shaft of the toggle in being installed on tubular axis, can cause and tubular axis all-in-one-piece knife rest produces bigger vibration, influence the reliability of complete machine use.
Summary of the invention
The purpose of this utility model is that the safe and reliable following cutter sweep of a kind of anticollision, low vibration is provided for all feeding-in combine with double-deck cutter sweep.
Technical solution of the present utility model is: it includes the following cutter group in the existing cutter sweep down, knife rest, be installed on the skid of knife rest front middle part bottom surface, the tubular axis that connects knife rest two side bar rearward end, connect the toggle of cutter group down, and be installed on crank connecting link power transmission shaft in the tubular axis by bearing, and and be connected in the skid pull bar between upper header and the knife rest, it is characterized in that the installation angle α≤30 ° between knife rest two side bars and the ground level.And its tubular axis is fixed on the rack chassis, and knife rest two side bar rearward end are connected with tubular axis by the anchor ear structure, remain with the free gap between anchor ear and the tubular axis.
The utility model is owing to the installation angle that has suitably dwindled between knife rest and the ground level, thereby when the skid under the knife rest collides ridge, can produce bigger upwards component, make knife rest two side bar rearward end directly upwards transfer lifting around tubular axis and play the knife rest leading section, it is impaired to avoid down the cutter group to insert ridge effectively; Simultaneously owing to taked tubular axis is fixed on the rack chassis, and allow knife rest both sides beam rearward end do freely rotating of certain angle around fixed tubular axle, thereby the toggle power transmission shaft in being installed on tubular axis when running, just seldom have influence on the knife rest that is connected with the fixed tubular axle appearance, thereby greatly reduce the vibration of knife rest, increased substantially the security reliability and the operating efficiency of complete machine work.

Embodiment
Embodiment, as accompanying drawing, knife rest 9 leading sections are equipped with down cutter group 11,12, knife rest front middle part bottom surface is equipped with skid 10, two side bar rearward end of knife rest 9 are provided with anchor ear structure 17, and be connected on the tubular axis 14,15 by anchor ear 17, remain with the free gap between anchor ear 17 and the tubular axis 14,15; On tubular axis 14,15, be positioned at anchor ear 17 both sides the back-up ring 13 that prevents the axial displacement of knife rest side bar is installed simultaneously; Installation angle α between 9 liang of side bars of knife rest and the ground level≤30 °; Tubular axis the 14, the 15th is fixed on the combine rack chassis 6 with holder 16, wherein be fixed with bearing 18 in the two ends of tubular axis 15, toggle power transmission shaft 7 is installed on the two bearings 18, the one end stretches out outside the tubular axis 15, and a drive sprocket 8 and an end that is connected the toggle 5 that drives the incision skive falchion movement are installed on this external part, sprocket wheel 8 is connected with the driving shaft 2 of upper header 1 by chain 3; Also be provided with chute pull bar 4 between upper header 1 operating mechanism and the knife rest 9.
