Description
Technical field
The invention belongs to combine harvester driver seat structure manufacturing fields, combine more particularly, to a kind of crawler type cereal
Harvester floating raft type driver seat structure, can be installed on extensively on all kinds of crawler type grain combine bridges.
Background technique
Current domestic crawler type grain combine mainly uses open bridge, and more invention and technology are also led
If carrying out improve and perfect on open bridge, as patent CN201410081085.0 discloses a kind of combine harvester
Bridge, by by clutch handle front end be arranged to toward upwarp certain angle and will by driver seat and front control tower into
The design of row trapezoidal shape, improves the safety of operation and effectively keeps away the danger that driving operation person topples over backward.Patent
CN201410081419.4 discloses a kind of cab seat of combine harvester, before designing realization seat to seat position
Afterwards, the function of up and down adjustment.Patent CN201610602990.5 discloses a kind of cropper seat assembly, by backrest
It adjusts before and after skeleton and angle tilt, the demand of the person that can be suitble to different operation and different sitting postures.But crawler type cereal is combined
Walking chassis is during by the uneven road in field, face exciting, drum threshing because feed quantity variation is drawn when harvester field harvests
Play that impact, more revolving body excitings couplings etc. cause the judder of complete machine in complete machine, driver is in operation combine harvester work
Also the physical and mental health of driver behavior personnel is affected by vibrations or even jeopardized when making.
To reduce influence of the body vibration to driver behavior personnel when crawler type cereal combines combine harvester field work,
Some Vibration Absorption Designings and improvement have also been carried out on driver behavior or driver seat structure.Patent CN201510239705.3 is disclosed
A kind of track combine floating riding manipulation platform passes through design three-level shock absorber section and chassis main frame and seat phase
Even, three layers of buffering and decaying are carried out to vertical motion.Patent CN201620205849.7 discloses a kind of harvester seat assembly,
It can be realized quick positioning to seat to fix, allow the operator to realize being switched fast for arm-rest frame and seat.At present to shoe
The oscillation damping method that belt grain combines combine harvester driver seat is mainly vertical level-one or multi-level damping, but can not be solved
The interference of oscillation crosswise suffered by driver seat；It is existing that level-one performance can be equivalent to using vertical level-one or multi-level damping system
Better damper, but it is difficult to eliminate in complete machine harvest multi-direction exciting force always to vibration caused by seat.
Summary of the invention
Because walking chassis is by the uneven road surface exciting in field, rolling when for crawler type grain combine field harvest
Cause to impact because feed quantity changes in cylinder threshing course, more revolving body excitings couplings etc. cause driver seat vibration simultaneously in complete machine
Jeopardize the physically and mentally healthy problem of driver behavior personnel, the present invention provides a kind of crawler type grain combine floating raft types to drive
