The working process and principle of the utility model are as follows:
when the utility model is used, the cage type soil scraping shovel 6 is firstly connected, and the specific operation process is as follows: the lower fluted disc 12 corresponds to the upper fluted disc 11; then the end part of the arc-shaped holding arm 9 is abutted against the lower side end face of the lower fluted disc 12; the adjusting nut 10 is rotated to make the pressing spring 13 tightly press the upper gear plate 11, and at this time, the lower gear plate 12 is tightly engaged with the upper gear plate 11. In the using process of the utility model: the operator holds the single-wheel handrail frame 1 with both hands and pushes the single-wheel handrail frame downwards along the slope of the slope to a transplanting point; when the cage type soil scraping shovel 6 is in a vertical state under the action of gravity, the control handle 17 is pressed, the transmission rope 18 pulls the L-shaped sliding block 16 to slide along the sleeve 15, the crank arm of the L-shaped sliding block 16 is clamped in a tooth gap of the adjusting gear 14 to realize locking of the adjusting gear 14, at the moment, the connecting seat 2 is relatively fixed, and the cage type soil scraping shovel 6 is also relatively fixed to the single-wheel handrail frame 1; then controlling the engine 3 to start, and driving the cage type soil scraping shovel 6 to rotate by the engine 3; the staff makes cage scraper blade 6 act on the slope soil layer through control single wheel handrail frame 1, and the plant cave of compound requirement is expanded out to the position accessible cage scraper blade 6 of constantly adjusting single wheel handrail frame 1, realizes digging the cave operation, covers the usable spade of hole and suitably clears up like the soil slick during the in-service use. The hole digging principle of the cage type scraper 6 is as follows: the transmission shaft 5 drives the connecting shaft 7 to synchronously rotate, the connecting shaft 7 drives the crescent shovel blade 8 to rotate, and the crescent shovel blade 8 realizes soil shoveling and scraping in the downward direction and the rotating circumferential direction by utilizing the shape characteristics of the crescent shovel blade 8 in the rotating process, so that the special slope scraper also adapts to the terrain characteristics of slopes; the broken stone can be pulled out along the trend when the crescent shovel blade 8 rotates, so that the influence of the broken stone on digging holes is avoided. A speed reducer may be added between the output shaft of the engine 3 and the drive shaft 5 in order to increase the torque at which the cage blade 6 rotates. If meeting great stone, the locking of crescent shovel piece 8, lower fluted disc 12 and last fluted disc 11 produce the friction and impel that last fluted disc 11 moves up, go up fluted disc 11 and further press after moving up and cover suppression spring 13, produce between lower fluted disc 12 and the last fluted disc 11 and slide, the tip of arc armful arm 9 slides on lower fluted disc 12 lower terminal surface simultaneously, and cage scraper 6 produces relative rotation with transmission shaft 5 this moment, avoids engine 3 to receive the damage. Cage scraper 6 can keep the tilt state to use in the in-service use process, uses more in a flexible way.
