Detailed ways

See Figures 1 and 2, the specific structure is as follows: a diesel engine 13 and a gearbox 10 are assembled on the frame 2, and the diesel engine 13 and the gearbox 10 are connected by transmission wheels 12, 9 and a transmission belt 11. The frame 2 is connected to the joystick 6, and the clutch handle 8 is assembled on the joystick 6, and the clutch handle 8 is connected to the clutch in the gearbox 10 through the clutch pull wire 7. Rotate and connect two walking chain support wheels 1 at the bottom of the frame 2, assemble a chain drive gear 25 in the middle of the top of the two travel chain support wheels 1, the chain drive gear 25 is five gears, and the chain drive gear 25 is coaxially connected with a large chain Wheel 26, large sprocket 26 is connected to the output sprocket 28 of gearbox by transmission chain 27. Traveling chain 23 is installed on two traveling chain supporting wheels 1 and on the chain driving gear 25. Weld trapezoidal bent plate 24 (seeing Fig. 7,8) on walking chain 23. See Fig. 1,3, weld guide cylinder 30 on frame 2, tooth bar 15 wears in the guide cylinder 30, and plow share 22 is welded on the lower end of tooth bar 15. Assemble the lifting gear 14 meshed with the rack 15 on the frame 2, the lifting gear 14 connects the gear arm 16, rotates and connects the plowshare lifting control lever 5 on the frame 2, and the gear arm 16 connects the plowshare lifting control lever 5 through the pull rod 3, The plowshare lifting control lever 5, the gear arm 16 and the pull bar 3 constitute a link mechanism. Assembling the joystick positioning plate 4 on the frame 2, a plurality of positioning holes 29 are arranged on the joystick positioning plate 4, and a positioning pin (not shown) inserted in the positioning hole is provided on the plowshare lifting joystick 5; see figure 1, 4, 5, 6, the guide wheel assembly 21 is provided with a rotating part, the rotating part includes a sleeve 33 sleeved on the shaft, the sleeve 33 is connected to the rotating plate 31, and the rotating plate 31 is provided with two wheels with different angles.
