Detailed Description

The directions shown in the drawings of the specification are up, down, left and right.

Referring to fig. 1, in order to improve grass cutting and harvesting efficiency, two blades 3 are used for cutting grass, and are driven by two dc motors one 901 respectively, and the two blades 3 with opposite rotation directions are arranged at the near front end of the bottom surface of the base plate 1. The blade 3 is provided with a current sensor. The baffle 4 capable of rotating 180 degrees is fixed on the bottom plate 1 through the rotating shaft 6 and the base 7. The baffle 4 is provided with a pressure sensor, the baffle 4 has the function of pushing the grass cut off by the blade 3 to move forwards, and the baffle 4 can properly adjust the pushing angle, so that the grass is prevented from falling on two sides of the mower to influence the next mowing work of the mower. The bottom plate 1 is internally provided with a microcontroller 2, a driving device 9 and a steering engine. The existing driving module enables the first direct current motor 901 to drive the blade 3, and the second direct current motor 902 to drive the wheels 10 of the mowing device. There is power 11 on bottom plate 1 upper surface, links firmly with camera 5 through connecting rod one 12, links firmly with ultrasonic ranging sensor through connecting rod two 13. Baffle 4 is through steering wheel control, and power 11, steering wheel, camera 5, obstacle avoidance sensor, angle sensor, current sensor, pressure sensor, ultrasonic ranging sensor 8 all link to each other with microcontroller 2. The obstacle avoidance sensor is arranged on the front side of the bottom plate 1, and the angle sensor is arranged on the side surface of the bottom plate 1.

As shown in fig. 2, after the power supply 11 supplies power to the microcontroller 2, the four dc motors two 902 respectively drive the four wheels 10 to travel, the two dc motors one 901 respectively drive the two blades 3 to rotate at a high speed, and the rotation directions of the two blades 3 are opposite. The obstacle avoidance sensor is used for identifying the obstacle, if the obstacle is identified, the signal is transmitted to the microcontroller 2, the microcontroller 2 drives the mower to avoid the obstacle, and if the obstacle is not identified, the mower continues to move forwards. Meanwhile, the horizontal state of the mowing device can be measured by using the angle sensor, and if the deviation is large, such as side turning and the like, the microcontroller 2 controls the blade 3 to stop running and stop walking. The current sensor is used for detecting the working condition of the double blades 3, and if one blade 3 is blocked, the microcontroller 2 stops the operation of the blade 3. The camera 5 is used for monitoring the mowing path and the mowing boundary of the mower, the boundary is identified, and if the boundary is reached, the mowing device moves forwards firstly, pushes grass to the boundary and then moves backwards to turn. In addition, the direction of the baffle 4 is controlled by the pressure sensor, if the pressure at one end of the baffle 4 is too high, information is transmitted to the microcontroller 2, and the baffle 4 is controlled to adjust the direction, so that the cut grass is not dropped on the uncut grass. The control programs referred to above are all conventional.
