Embodiment 1
[0041] Such as Figure 1-13 Shown: the rice combine harvester of the present invention front and rear steering operation mechanism is made up of drive wheel 1, drive gear 2, the drive axle shaft 3 that is positioned at drive gear 2 two ends, bearing 4, axle shaft sleeve 5, return spring 6, static friction clutch Plate 7, clutch hub 8, ball clutch hub 9, dynamic friction clutch plate 10 and clutch wave plate 11, gearbox 12, gear transmission box 13, shift fork 14, pull wire 15, rear operating mechanism 16, front operating mechanism 17, the first A guide plate 19, the second guide plate 18 and other components are formed.
[0042] The output shaft of the gearbox 12 is connected with the input shaft of the gear transmission box 13, and the terminal gear of the gear transmission box 13 meshes with the drive gear 2. This is a prior art, and will not be repeated here.
[0043] The driving gear 2 includes a central cylinder 21, and a gear 22 is integrally formed in the middle of the...

The invention discloses a forward-backward steering operating mechanism for a steering rice combine harvester. The operating mechanism comprises a driving wheel, a driving gear and a driving semi-shaft, wherein one end of the driving semi-shaft is connected with the driving gear, and the other end of the driving semi-shaft is connected with the driving gear; the driving semi-shaft is synchronously provided with a ball clutching hub and a braking system, the ball clutching hub controls the driving semi-shaft to rotate along with the driving gear or separate from the driving gear, and the braking system is controlled to brake by the movable control of a clutch wave disc on the ball clutching hub; shifting forks are arranged on the clutch wave disc, each shifting fork is provided with three pull wires, one of the three pull wires is respectively connected with a rear left steering handle and a rear right steering handle of a rear steering mechanism, and the other pull wires of the two shifting forks are simultaneously connected with a parking handle of the rear steering mechanism. The third pull wire is connected with a left steering connecting rod and a right steering connecting rod of the front steering mechanism, and one shifting fork needs to be installed on the clutching wave disc only, therefore two operating systems are simple in structure and flexible to operate.
Description
technical field [0001] The invention relates to a front and rear steering operation mechanism of a rice combine harvester. Background technique [0002] The drive axle widely used in combine harvesters is developed on the basis of Gongnong-12 walking tractor gearbox, and the clutch, brake and steering system is unstable. In addition, the clutch hub of the existing drive axle is not installed on the drive half shaft, but is installed on the gear box, and the brake is installed on the drive half shaft, so two shift forks are needed, one for clutch and one for clutch. Braking, troublesome operation, inflexible, poor adjustability of turning radius. [0003] In addition, at present, only one operating mechanism is arranged on the rice combine harvester, which is located at the operating platform, and the operator can only operate on the operating platform, and the people behind cannot operate turning and parking. Contents of the invention [0004] Aiming at the existing prob...
