Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
As shown in fig. 1, 2, 3, 4, an obstacle avoidance power adjusting device of obstacle avoidance mower for orchard comprises a straight beam 1, a U-shaped frame 2, an oil tank 3, a gear box 4, a hydraulic station 5, an obstacle avoidance support beam 6, a limiting device 7, a cutting knife swing arm 8, a motor support frame 9, a hydraulic motor 10, an obstacle avoidance rotating wheel 11, a mowing blade 12, an obstacle avoidance device 13, and is characterized in that: the U-shaped frame 2 is fixed behind the straight beam 1; the oil tank 3 is fixed above the straight beam 1; the gear box 4 is positioned above the straight beam 1 and on the right side of the oil tank 3; the hydraulic station 5 is positioned above the straight beam 1 and on the right side of the gear box 4; the obstacle avoidance support beam 6 is fixed in front of the straight beam 1; the limiting device 7 is connected to the right side of the straight beam 1 and can rotate; the cutting knife swing arm 8 is fixed in front of the limiting device 7; the motor support frame 9 is fixed in front of the cutting knife swing arm 8; the hydraulic motor 10 is positioned at the inner side of the motor supporting frame 9; the obstacle avoidance rotating wheel 11 is positioned below the motor supporting frame 9; the mowing blade 12 is connected with the hydraulic motor 10 and is positioned below the obstacle avoidance rotating wheel 11; the obstacle avoidance device 13 is composed of a spring pre-tightening knob 131, a spring outer column 132, a spring 133, a spring fixing column 134, an O-shaped connecting frame 135 and a shaft sleeve 136, the spring pre-tightening knob 131 is connected to the left side of the spring outer column 132, the spring 133 is located on the inner side of the spring outer column 132 and connected with the spring pre-tightening knob 131, the spring fixing column 134 is located between the spring 131 and the cutting knife swing arm 8, the O-shaped connecting frame 135 is fixed to the outer side of the spring outer column 132, the shaft sleeve 136 is fixed to the upper surface of the obstacle avoidance support beam 6, and the shaft sleeve 136 is connected with the O-shaped connecting frame 135.
