Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and the implementation of the mechanism diagram of the machine.

As shown in Figures 1 to 3, the two-wheel drive rice transplanter of the present invention mainly includes a frame, an engine 1, a gearbox 4, an operating mechanism, a driving wheel, a rice transplanting working mechanism and a transport wheel. The racks may include a front rack 33 and a rear rack 12 . Wherein, the engine 1 is fixedly installed on the front frame 33, the gearbox 4 is connected with the front frame 33 and the rear frame 12, and the operating mechanism is installed on the rear frame 12. The driving wheel comprises a left driving wheel 21 and a right driving wheel 22, and the left driving wheel 21 and the right driving wheel 22 are respectively connected with the gearbox 4 by the driving wheel chain 29 in the left driving wheel sprocket box 24 and the right driving wheel sprocket box 25 , The rice transplanting working mechanism is connected with the rice transplanter hitch 14, and the rice transplanter hitch 14 is connected with the rear frame 12. The walking power of the rice transplanter of the present invention relies on two driving wheels on both sides of its front portion, namely the left driving wheel 21 and the right driving wheel 22.

The steering mechanism includes a seat 11 , a left steering lever 7 and a right steering lever 8 . The seat 11 is arranged on the rear frame 12 . The operator sits on the seat 11 and puts his feet on the left pedal 27 and the right pedal 28 respectively. The left steering joystick 7 and the right steering joystick 8 can be installed on the rear frame 12 or directly on the gearbox 4 . And, the left steering lever 7 and the right steering lever 8 are connected with the gearbox 4 through corresponding steering clutch pull wires. Specifically, the right steering lever 8 is connected with the right steering clutch rocker arm 3 in the gearbox 4 through the right steering clutch cable 6; the left steering lever 7 is connected with the left steering clutch rocker in the gearbox 4 through the left steering clutch cable 5. Arm 2 is connected. Seen from Fig. 3: the turning of left driving wheel 21 and right driving wheel 22 is through the rotation of left steering joystick 7 or right steering joystick 8, pull left steering clutch backguy 5 or right steering clutch backguy 6, drive left steering clutch The rocker arm 2 or the right steering clutch rocker arm 3 moves to control the power combination and cutoff of the left drive wheel 21 and the right drive wheel 22 to realize the steering of the machine.

The middle part of sprocket box support 26 is connected with the bottom of rear frame 12, and one end of sprocket box support 26 is connected with left drive sprocket box 24, and the other end is connected with right drive sprocket box 25. It can be seen from Fig. 1 and Fig. 2 that the engine 1 and the rice transplanting working mechanism are respectively connected with the gearbox 4 through the transmission mechanism: the power of the engine 1 passes through the V-belt 32, and is decelerated by the engine pulley 34 and the gearbox pulley 31 and enters the gearbox 4. The power of the gearbox 4 is divided into two parts for output. The first part is output to the left drive wheel 21 and the right drive wheel 22 through the gearbox sprocket 30, the drive wheel chain 29 and the drive wheel sprocket 23.
