The bottom of the arc plate 404 is provided with a large baffle 414. Since the arc frames 418 are symmetrically arranged on both sides of the arc plate 404, when the arc plate 404 and the arc support plate 420 rotate, if the opening of the arc plate 404 is facing one of the sets of toothed belts 428, the other set of toothed belts 428 will also come into contact with the arc toothed ring 419 on the arc plate 404. The arc plate 404 is combined, and the arc plate 404 can always rotate. Two sets of third universal wheels 421 are arranged on the back of the large baffle 414.

[0043] A side frame 412 is fixedly provided on the mounting frame 403, and a driving wheel 422 and a plurality of sets of auxiliary driving wheels 423 are rotatably provided on the side frame 412. A toothed belt 428 is sleeved on the outer portion of the driving wheel 422 and the auxiliary driving wheel 423. An arc-shaped toothed ring 419 is fixedly provided on the top of the outer wall of the arc-shaped plate 2 404, and the arc-shaped toothed ring 419 is meshed with the toothed belt 428.

[0046] Embodiment 2

[0047] Based on Example 1, please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.12 and Fig.13 The adaptive lifting assembly includes an L-shaped plate 402 fixed on a large baffle plate 414, wherein a plurality of sliding grooves are provided inside the L-shaped plate 402, wherein a T-shaped plate 416 is provided inside the sliding groove for sliding, and a lifting scraper 415 is fixedly provided on the bottom surface of the T-shaped plate 416. When the bottoms of the plurality of lifting scrapers 415 are on the ground with a slope, they are not at the same height according to the ground with a slope, and the large baffle plate 414 and the lifting scraper 415 are provided in an inclined manner, so as to facilitate the scraping of the soil into the pit;

[0048] The top of the T-shaped plate 416 is fixedly provided with a mounting spring 426, the top of the mounting spring 426 is fixedly provided with a lower block 427, the top of the lower block 427 is provided with a disc 417, the disc 417 is fixed on the L-shaped plate 402, the disc 417 and the lower block 427 are fixedly connected by a first bolt, the disc 417 and the lower block 427 can be fixed or separated by the first bolt, so that when the mounting spring 426 is damaged after long-term use, the first bolt can be unscrewed to move the T-shaped plate 416 downward The movement drives the installation spring 426 and the lower block 427 to move accordingly, and then the lower block 427 is separated from the sliding groove, and the T-shaped plate 416, the installation spring 426 and the lower block 427 are taken out, and a new one is taken out and installed back to the original position according to the above reverse principle, and the replacement is completed. The bottom of the T-shaped plate 416 is fixedly connected to the lifting scraper 415 by a second bolt. When the lifting scraper 415 is damaged, the second bolt is unscrewed, and then the lifting scraper 415 is removed and replaced with a new lifting scraper 415;

[0049] A circular block 413 is fixedly provided at the bottom of the arc-shaped plate 404, and two groups of upper studs 425 are fixedly provided at the top of the L-shaped plate 402. The upper studs 425 are fixed to the top of the L-shaped plate 402, and the tops of the upper studs 425 pass through the interior of the circular block 413, and the exterior of the upper studs 425 is connected with a spiral ring 424 through threads.

[0050] The present invention has a designed backfilling mechanism. After a hole is dug by the spiral drill rod 108, the saplings are planted in the dug hole. Then, the soil around the hole is scraped into the hole by the rotating large baffle plate 414 and the lifting scraper 415 to achieve backfilling. The T-shaped plate 416 slides in the sliding groove of the L-shaped plate 402, and the spring 426 is installed to realize the adaptive lifting of multiple lifting scrapers 415 according to the different slopes of the revetment forest ground. The soil on the ground can be scraped into the corresponding hole according to the ground conditions, thereby increasing the backfilling effect. In addition, the large baffle plate 414 and the lifting scraper 415 can adjust their positions according to the different diameters of the dug holes, thereby increasing applicability.

[0051] In summary, when the lifting frame 100 moves to the ground of the bank protection forest, since some bank protection forests have a slope, the first hydraulic rod 103 and the second hydraulic rod 405 at the bottom of the lifting frame 100 and the fixed frame 408 are opened, and the working ends of the first hydraulic rod 103 and the second hydraulic rod 405 are extended to different lengths respectively so that the first skid plate 105 and the second skid plate 407 below can automatically fit the ground with a slope, and then the rotating auger rod 108 is used to dig a hole in the ground. After the hole is dug, the ground around the hole is slid by the auger rod 108. A lot of soil will be turned over and piled around the pit, and then the lifting frame 100 moves to the left front, driving the Z-shaped frame 400, the fixed frame 408 and other structures to move with it. During the movement, the operator puts the sapling from the position between the two sets of Z-shaped frames 400 into the corresponding dug pit. At this time, the opening of the arc plate 2 404 faces the left direction, and then with the movement of the fixed frame 408, the sapling enters the middle position of the arc plate 2 404. At this time, the equipment stops moving, and then the installation motor 411 is turned on, and the working end of the installation motor 411 drives the active wheel 42 2 rotates to drive the external toothed belt 428 to rotate, and the toothed belt 428 drives the multiple sets of auxiliary driving wheels 423 and the arc-shaped toothed ring 419 to rotate, and then the arc-shaped plate 404 can be driven to rotate. At this time, the arc-shaped plate 404 drives the fixed circular block 413 below to rotate, and then drives the L-shaped plate 402, the large baffle 414 and the lifting scraper 415 to rotate. Because the ground is a slope with a slope, at this time, the different lifting scrapers 415 bottoms touch the ground and the installed springs 426 begin to expand and contract, driving the T-shaped plate 416 to slide The bottom of the different lifting scrapers 415 can be adaptively fitted to the ground according to the slope to increase the backfilling amount of soil on the ground. Then, the soil around the pit above the pit is scraped into the pit by the rotating large baffle 414 and the lifting scraper 415 to achieve backfilling. Then, the rotating arc plate 2 404 rotates until the opening is on the right and stops. At this time, the installation motor 411 stops running. Then the lifting frame 100 and the fixing frame 408 continue to move to the left, and the saplings in the pit are separated from the arc plate 2 404, completing the backfilling of soil.

[0052] When the diameter of the dug pit is different, the distance between the large baffle 414, the lifting scraper 415 and the pit is adjusted so that the large baffle 414 and the lifting scraper 415 are close to the edge of the pit. When adjusting, first loosen the spiral ring 424 by turning it upward, and then move the upper stud 425 to the left or right in the circular block 413, which can drive the lower L-shaped plate 402 and the lifting scraper 415 to move. After moving, turn the spiral ring 424 downward and tighten it to adjust it.

[0053] Embodiment 3

[0054] Based on Example 2, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 A watering piece is provided on the fixed frame 408, and the watering piece includes a pipe rack 502 fixed on one side of the fixed frame 408 and a concave baffle 500 fixed on the fixed frame 408. A plurality of groups of oblique sprinklers are fixedly provided at the end of the pipe rack 502. A pipe connection 505 is fixedly provided on the pipe rack 502. When in use, an external water pipe is connected to the pipe connection 505 to supply water to the oblique sprinklers.

[0055] The surface of the concave baffle 500 is rotatably connected to two groups of rotating baffles 501 via a rotating shaft, the front and back sides of the rotating baffle 501 are fixedly provided with a first T-shaped head, and multiple groups of second T-shaped heads are fixedly provided on the concave baffle 500. A telescopic spring 504 is provided between the first T-shaped head and the second T-shaped head, and multiple groups of mounting soft belts 503 are fixedly provided at the bottom of the concave baffle 500 and the rotating baffle 501.

[0056] The watering piece of the present invention can carry out targeted watering on the pit where the saplings have just been planted through the multiple groups of inclined nozzles at the end of the pipe rack 502, ensuring that the water directly acts on the roots of the saplings, and the concave baffle 500 and the rotating baffle 501 are connected by a rotating shaft, so that the rotating baffle 501 can rotate and adaptively adjust the angle after contacting the saplings in the pit as the fixed frame 408 moves. When the sapling is located between the two groups of rotating baffles 501, watering is carried out. During the watering process, the concave baffle 500 and the rotating baffle 501 can effectively prevent the probability of water splashing outwards during watering, and guide the water flow to flow to the sapling pit. At the same time, the multiple groups of mounting soft belts 503 at the bottom of the concave baffle 500 and the rotating baffle 501 can further play a role in preventing water from splashing outwards according to different ground slopes.

[0057] In summary, after the backfilling is completed, as the fixed frame 408 moves to the left, the watering piece is driven to move along, and then the end of the rotating baffle 501 on the watering piece contacts the sapling. At this time, the middle position of the rotating baffle 501 located on the left side of the concave baffle 500 is blocked by the sapling and then rotates to the right to adjust the angle. At this time, the telescopic spring 504 begins to retract. Then, after rotating to a certain angle, the end of the rotating baffle 501 on the left side is separated from the surface of the sapling. At this time, the rotating baffle 501 is reset under the telescopic action of the telescopic spring 504, and then the sapling is located between the two groups of rotating baffles 501. At this time, the equipment is stopped, and then the inclined sprinkler is turned on to spray water at the pit position to achieve watering. When the watering is completed, the equipment is turned on to move in the same way as above. As the fixed frame 408 moves, the middle position of the rotating baffle 501 on the right side contacts the sapling and rotates, and finally the rotating baffle 501 on the right side is separated from the sapling.

[0058] Embodiment 4

[0059] Based on Example 3, please refer to Figure 1-Figure 7 A lifting cylinder 101 is provided on the ring frame 102, a driving motor 107 is fixedly provided on the working end of the lifting cylinder 101, the top of the auger rod 108 is fixed to the working end of the driving motor 107, a blocking member is provided on the outside of the auger rod 108, and the blocking member includes a telescopic ring 200 provided on the outside of the auger rod 108, and two sets of upper frames 201 are fixedly provided between the top of the telescopic ring 200 and the ring frame 102;

[0060] An arc plate 203 is fixedly provided at the bottom of the upper frame 201, a bottom ring 205 is fixedly provided at the bottom of the telescopic ring 200, two sets of extension screws 202 are fixedly provided outside the bottom ring 205, and a screw ring 204 is connected to the outside of the extension screw 202 through a thread.

[0061] The blocking member designed in the present invention can prevent soil from being carried out by the high-speed rotating auger rod 108 and splashing around during the digging process of the auger rod 108. The telescopic ring 200 arranged on the outside of the auger rod 108 can block the splashing soil like a barrier to prevent the soil from splashing onto the operator or surrounding equipment, thereby improving the operating environment and preventing the soil from splashing far around the pit, thereby facilitating subsequent soil backfilling operations.

[0062] In summary, when the auger rod 108 rotates and descends to dig a hole in the ground, the external telescopic ring 200 is driven to descend, and the telescopic ring 200 outside the auger rod 108 is used for blocking and protection to prevent the auger rod 108 from driving a lot of soil to splash outward during the rotation and digging process. The soil splashes and hits the inner wall of the telescopic ring 200 and then falls and accumulates around the pit. When the pit is dug, the auger rod 108 rises and drives the telescopic ring 200 to rise. If the telescopic ring 200 is not needed to block, the bottom ring 205 at the bottom of the telescopic ring 200 is moved upward to make the telescopic ring 200 begin to compress, and then the two sets of extension screws 202 on the bottom ring 205 are inserted into the interior of the arc plate 1 203, and finally the screw ring 204 on the extension screw 202 is rotated and tightened in the direction close to the telescopic ring 200 to fix the bottom ring 205, thereby retracting the telescopic ring 200, and when needed later, the telescopic ring 200 can be opened according to the above-mentioned reverse principle.

[0063] In this embodiment, a storage box 300 is fixedly arranged between the two groups of Z-shaped frames 400, and fertilizer is loaded in the storage box 300. A lower tube 302 is fixedly arranged at the bottom of the storage box 300, and a plurality of lower soft belts 301 are fixedly arranged at the bottom of the lower tube 302. After the pit is dug, the fertilizer in the storage box 300 falls into the pit below for timely fertilization, and there is no need to perform fertilization operation again later. Moreover, the lower soft belt 301 located at the bottom of the lower tube 302 can be bent according to the undulation and slope of the ground. The lower soft belt 301 is used for blocking and protection, which can reduce the probability of the fertilizer placed in the pit splashing outward.

[0064] In this embodiment, rotating rods are provided at both ends of the ring frame 102, and the ends of the rotating rods pass through the interior of the lifting frame 100. The interior of the lifting frame 100 is connected with locking screws 106 by threads. When the equipment is not dug, the rotating rods can be fixed by the locking screws 106 during transportation or moving the equipment to prevent the ring frame 102 from swaying due to the bumps generated during transportation. When the equipment is used, the locking screws 106 are unscrewed to make its working end detach from the surface of the rotating rod for use, and the bottom of the locking screws 106 extends to the surface of the rotating rod. Two groups of first hydraulic rods 103 are fixedly provided at the bottom of the lifting frame 100. When the equipment is placed on a sloping ground, multiple first hydraulic rods 103 and multiple second hydraulic rods 405 are started, so that the bottoms of the first skid plate 105 and the second skid plate 407 can fit on the sloping ground. In addition, when the equipment is not dug, the working ends of the first hydraulic rods 103 and the second hydraulic rods 405 are retracted during the movement to make the first skid plate 105 and the second skid plate 407 fit on the sloping ground. The second skid plate 407 is no longer in contact with the ground, and the first universal wheel 104 and the second universal wheel 406 are in contact with the ground, which is convenient for movement.
