Floating raft driving seat structure of crawler grain combine harvester

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.

Description

technical field [0001] The invention belongs to the field of manufacture of a driving seat structure of a combine harvester, and in particular relates to a floating raft driving seat structure of a crawler grain combine harvester, which can be widely installed on the driving platforms of various crawler grain combine harvesters. Background technique [0002] At present, the domestic crawler grain combine harvester mainly adopts an open bridge, and many inventions and technologies are mainly improved and perfected on the open bridge. For example, the patent CN201410081085.0 discloses a combine harvester bridge , by setting the front end of the clutch handle at a certain angle upwards and designing the driver's seat and the front control tower in a trapezoidal shape, the safety of the operation is improved and the danger of the operator falling backward is effectively avoided. Patent CN201410081419.4 discloses a cab seat of a combine harvester, which realizes the function of a...

AI Technical Summary

Problems solved by technology

[0004] For crawler-type grain combine harvesters, the driving chassis is excited by the uneven road surface in the field during field harvesting, the impact caused by changes in the feeding amount during the drum threshing process, and the vibration coupling of multiple rotating bodies on the whole machine all cause vibration of the driver's seat. To solve the problem of endangering the physical and mental health of driving operators, the present invention provides a floating raft driving seat structure for crawler grain combine harvesters
