Title:
FLOTATION RAFT TYPE DRIVING SEAT STRUCTURE OF CRAWLER-TYPE CEREAL COMBINE HARVESTER
Document Type and Number:
WIPO Patent Application WO/2018/233094
Kind Code:
A1
Abstract:
Disclosed is a flotation raft type driving seat structure of a crawler-type cereal combine harvester, comprising a driving seat structure (4), a flotation raft bearing stage (5), a left roller shock-absorber (6), a right roller shock-absorber (7) and a vertical shock-absorber (8), wherein an upper side of the flotation raft bearing stage (5) is connected to the driving seat (4) structure, left and right sides of the flotation raft bearing stage (5) are respectively connected to the left roller shock-absorber (6) and the right roller shock-absorber (7), and a lower side of the flotation raft bearing stage (5) is connected to the vertical shock-absorber (8). When vibration of a driving station base bearing plate (3) is transferred to the flotation raft bearing stage (5), the vertical shock-absorber (8) performs frequency filtering and vibration isolation, residual excitation force is balanced by bending resistance and resilience of a transverse helical compression spring (705). When vibration of a side wall of a driving cab is transferred to the flotation raft bearing stage (5), a left roller (702) and a right roller (702) respectively roll on a circular arc of a bearing stage left arc plate (503) and a bearing stage right arc plate (502) to eliminate the excitation force of the side wall of the driving cab. The seat structure is simple, low in cost and has good universality, and can be used for eliminating excitation of the seat caused by the side wall of the driving cab and the driving station base bearing plate during operation of the crawler-type cereal combine harvester.
