And thirdly, the motor (12) is electrified to be started, the gear (13) arranged at the shaft end of the motor rotates, the gear (13) and the end face worm wheel (14) are in meshed transmission, the driving shaft (15) arranged with the end face worm wheel (14) starts to rotate, so the driving wheels (16) rotate, the rubber crawler (17) is transmitted between the upper driving wheel (16) and the lower driving wheel (16), two driven wheel devices (18) are arranged between the two driving wheels (16), the driven wheel devices (18) are arranged in three sections of connecting rods (19), 2 driven wheels (20) are arranged on each section of connecting rod (19), 2 pairs of driven wheels are arranged on one side, the other 1 pair of driven wheels are arranged on the other side, and the rubber crawler (17) is in a trapezoidal shape after being installed, so that the rubber crawler (17) can be more tightly attached to a tree body when in transmission and walking. When the rubber crawler belt (17) moves upwards in contact with the tree body, the upper rubber tire and the lower rubber tire in the tree holding mechanism (2) synchronously move upwards along with the rubber crawler belt.
Fourthly, when the device moves upwards, the device starts to clean the residual branches, the servo motor (31) is electrified and started, the driving gear (33) rotates, so that the driven gear (34) rotates along with the driving gear, the rotating shaft is driven to rotate for a certain angle, the swing arm (28) is driven to rotate for a certain angle, the synchronous motor (30) is started, the driving gear II (36) arranged at the shaft end rotates, the driven gear II (38) rotates, so that the gear part of the gear shaft (41) is driven to rotate, namely, the lower scraper (40) rotates for a certain angle along with the driving gear, 2 synchronous motors (30) of the two parts are started to work simultaneously, finally, when the device moves upwards, 2 lower scrapers (40) are driven to form a proper angle to scrape branches and leaves on the tree body, the cross sections of the upper scrapers and the lower scrapers are arc-shaped, the upper scrapers and the lower scrapers are matched, and the upper scrapers (40) can move on the places where the upper scrapers pass through, the angle is adjusted through the matching of the pair of lower scrapers.
