现有的机耕船主要采用导向轮进行转向。当机耕船左转时，方向盘逆时针转动，前轮相对地面逆时针转一定角度，实现机耕船左转。这种转向方式的实现依靠的是轮子和地面的摩擦，然而当机耕船在深泥脚田耕作时，车轮与地面摩擦力较小，此时依靠这种转向方式转向往往存在转向操作复杂，转向时间长，容易打滑等不足。 Existing mechanical farming boat mainly adopts guide wheel to turn. When the mechanical farming boat turns left, the steering wheel turns counterclockwise, and the front wheel turns counterclockwise at a certain angle relative to the ground, so that the mechanical farming boat turns left. The realization of this steering method depends on the friction between the wheels and the ground. However, when the mechanical tiller is plowing in the deep muddy field, the friction between the wheels and the ground is small. At this time, relying on this steering method often has complicated steering operations and time-consuming steering operations. Long, easy to slip and other deficiencies.

As shown in Figure 1 and Figure 2, a linkage hydraulic steering brake device for mechanical farming boats, including a double-rod steering master cylinder (19), the double-rod steering master cylinder (19) and full hydraulic steering The controller (9) is connected, and the full hydraulic steering controller (9) is connected with the steering wheel (10), and the steering wheel (10) controls the full hydraulic steering controller (9), thereby controlling the double-outlet steering master cylinder (19 ) the piston rod moves left and right. The full hydraulic steering controller (9) can respectively push the left steering brake master cylinder (7) and the right steering brake master cylinder (12), and the left steering brake master cylinder (7) and the first speed regulating The valve (6) is connected, the first speed regulating valve (6) controls the left front wheel proportional valve (3) and the left rear wheel two-way brake cylinder (1), the right steering brake master cylinder (12) and the second The two speed regulating valves (13) are connected, and the second speed regulating valve (13) controls the right front wheel proportional valve (16) and the right rear wheel two-way brake cylinder (18). Combined with the schematic diagram of unilateral braking to realize differential steering as shown in Figure 2, the steering wheel (10) rotates to drive the full-hydraulic steering controller (9), and the full-hydraulic steering controller (9) drives the double-outlet steering master cylinder (19), When the double-out rod steering master cylinder (19) turns left, the left rod will promote the left steering brake master cylinder (7) to brake the left side, so as to achieve the purpose of differential steering, and the tiller will turn left. When the double-outlet rod steering master cylinder (19) turns rightward, the right-hand outrod will push the right steering brake master cylinder (12) to brake the right side, thereby achieving the purpose of differential steering, and the tiller will turn rightward.
如图1所示的液压制动转向系统，左、右转向制动主缸（7、12）分别与左、右制动主缸相连（25、21），所述左、右制动主缸（25、21）分别与左、右制动踏板（23、22）相连，所述左、右制动踏板（23、22）带有互锁机构（24）。当两个踏板互锁时，脚踩任何一个踏板都能实现推动左、右制动主缸运动，从而实现双边制动。当两个脚踏板互锁机构打开时，踩左边制动踏板（23）可实现左边制动，以辅助方向盘（10）左边转动。同样，踩右边制动踏板（22）可实现右边制动，以辅助方向盘（10）右边转动。 In the hydraulic brake steering system shown in Figure 1, the left and right steering brake master cylinders (7, 12) are connected to the left and right brake master cylinders (25, 21) respectively, and the left and right brake master cylinders (25, 21) are respectively connected with the left and right brake pedals (23, 22), and the left and right brake pedals (23, 22) are provided with an interlock mechanism (24). When the two pedals are interlocked, stepping on any one of the pedals can push the left and right brake master cylinders to move, thereby realizing bilateral braking. When the two pedal interlocking mechanisms were opened, stepping on the left brake pedal (23) can realize left braking to assist the left rotation of the steering wheel (10). Equally, stepping on the brake pedal (22) on the right side can realize braking on the right side, so as to turn the right side of the auxiliary steering wheel (10).
图1中左边转向制动主缸（7）、右边转向制动主缸（12）、右制动主缸（21）、左制动主缸（25）分别与油箱（8）相连，当制动系统出现漏油时，可从油箱吸油进行补给，其中单向阀（20）可保证制动或转向时左、右转向制动主缸及制动主缸的油往制动器的制动缸里单向流，不出现回流。左、右转向制动主缸（7、12）及左、右制动主缸（25、21）在不制动时，其活塞在外方向极限位置，即在不转向时，左、右转向制动主缸（7、12）的活塞不能向右、左运动，即在制动时，左、右制动主缸（25、21）中流出的油只能向车轮上的双向制动缸（1、5、14、18）里流动，并不能流进左、右转向制动主缸（7、12），同样，当未踩制动踏板里，往左边转向时，左边转向制动缸（7）中流出的油只能向左前轮双向制动缸（5）的里流动，并不能流进左制动主缸（25）。 In Figure 1, the left steering brake master cylinder (7), the right steering brake master cylinder (12), the right brake master cylinder (21), and the left brake master cylinder (25) are respectively connected with the fuel tank (8). When there is oil leakage in the braking system, oil can be sucked from the oil tank for replenishment, and the one-way valve (20) can ensure that the oil in the left and right steering brake master cylinder and the brake master cylinder goes to the brake cylinder of the brake during braking or steering. One-way flow, no backflow. When the left and right steering brake master cylinders (7, 12) and the left and right brake master cylinders (25, 21) are not braking, their pistons are at the limit positions in the outward direction, that is, when not turning, the left and right steering brakes The pistons of the active master cylinders (7, 12) cannot move right and left, that is, when braking, the oil flowing out from the left and right brake master cylinders (25, 21) can only flow to the two-way brake cylinders ( 1, 5, 14, 18), and cannot flow into the left and right steering brake master cylinders (7, 12). Similarly, when the brake pedal is not stepped on, when turning to the left, the left steering brake cylinder ( 7) The oil flowing out of the cylinder can only flow into the left front wheel two-way brake cylinder (5), and cannot flow into the left brake master cylinder (25).
