[0021] Furthermore, the adjusting ring 545 rotates and drives the bevel gear 1 542 and the bevel gear 2 543 to rotate through the bevel gear 3 544, and the bevel gear 1 542 and the bevel gear 2 543 rotate in opposite directions, and the bevel gear 1 542 and the bevel gear 2 543 then respectively drive the cylinder 534 and the round rod 535 to rotate, and the rotation directions of the cylinder 534 and the round rod 535 are opposite; The rotation of the cylinder 534 drives the multiple arc blocks 532 to rotate synchronously, and the rotation of the round rod 535 drives the multiple synchronous arc blocks 531 to rotate through the multiple shifting blocks 5351, and the rotation directions of the multiple arc blocks 532 and the multiple arc blocks 531 are opposite, and the shifting block 5351 can only rotate 0-180° in the arc hole 5341.

[0022] An adjusting mechanism 54 is installed at the top of the drill rod 52, and the adjusting mechanism 54 includes a box body 541 with a bottom fixedly connected to the top of the drill rod 52, and a bevel gear 1 542 and a bevel gear 2 543 coaxial with the drill rod 52 are rotatably installed in the box body 541, the cylinder 534 rotates to penetrate the drill rod 52 and rotates to extend into the box body 541, and it penetrates the bevel gear 1 542 and is fixedly connected to the bevel gear 1 542, the round rod 535 rotates to penetrate the cylinder 534 and the box body 541 and penetrates the bevel gear 2 543 and is fixedly connected to the bevel gear 2 543, the bevel gear 1 542 and the bevel gear 2 543 are meshed with the same bevel gear 3 544, and an adjusting ring 545 fixedly connected to the bevel gear 3 544 is rotatably installed on the box body 541.

[0023] A material trough 5312 is provided at the top of the arc block 531, and a plurality of release holes 5313 are provided on the inner wall of the material trough 5312 at equal intervals.

A third blade edge 5324 and a fourth blade edge 5325 are respectively provided on the top and bottom edges of the second arc block 532.

[0025] Furthermore, granular fertilizer can be placed in advance through the material trough 1 5312 and the material trough 2 5322. After the arc block 1 531 and the arc block 2 532 are inserted into the quicksand, as the openings of the material trough 1 5312 and the material trough 2 5322 face upward, the granular fertilizer in the material trough 1 5312 and the material trough 2 5322 can be exposed. When irrigation is subsequently performed, irrigation water can enter the material trough 1 5312 and the material trough 2 5322 from the top opening, so that the granular fertilizer therein can be accelerated to degrade. In addition, since the arc block 1 531 and the arc block 2 532 are located below the intersection node 4, they are far away from the planting area 3 where plants are planted, and fertilizer root burn will not occur.

[0026] Sand barrier 1 and sand barrier 2 2 are fabric bags made of biodegradable material, which are a mixture of polylactic acid fiber and at least one of regenerated protein fiber, regenerated cellulose fiber or natural fiber, and the fabric bags are filled with local quicksand.

[0027] A method for planting auxiliary vegetation in desert quicksand fixing is applicable to the above-mentioned device for planting auxiliary vegetation in desert quicksand fixing, and comprises the following steps: S1, firstly, the quicksand land to be planted is leveled, and then a plurality of positioning and lifting components 5 are fixed in a matrix on the quicksand land to be planted; S2, then weave multiple sand barriers 1 and multiple sand barriers 2 in a crisscross manner horizontally and vertically, and carry and position the intersection nodes 4 of each sand barrier 1 and each sand barrier 2 through multiple positioning and lifting components 5; S3, based on S2, plants can be planted in multiple planting areas 3 formed between multiple sand barriers 1 and multiple sand barriers 2 arranged in a horizontal and vertical manner; In this embodiment, when the positioning and lifting assembly 5 is fixed in the quicksand, firstly, each positioning mechanism 53 on the positioning and lifting assembly 5 is in an initial state. Figure 8 As shown, at this time, each of the first trough 5312 and the second trough 5322 is pre-placed with granular fertilizer, and then the plurality of positioning mechanisms 53 are inserted into the quicksand, and the supporting plate 51 is placed in a horizontal state and its bottom is in contact with the quicksand; Then, the adjusting rings 545 on each adjusting mechanism 54 are turned in turn, and the adjusting rings 545 rotate and drive the bevel gear 1 542 and the bevel gear 2 543 to rotate through the bevel gear 3 544, and the rotation directions of the bevel gear 1 542 and the bevel gear 2 543 are opposite. The bevel gear 1 542 will drive the multiple arc blocks 2 532 to rotate synchronously through the cylinder 534, and the bevel gear 2 543 will drive the multiple arc blocks 1 531 to rotate synchronously through the round rod 535, and the rotation directions of the multiple arc blocks 2 532 and the multiple arc blocks 1 531 are opposite. After the four adjusting rings 545 on the positioning and lifting assembly 5 are all rotated, the positioning and lifting assembly 5 is Fig. 9 Shown in the expanded state; Fig. 9 The arc blocks 1 531 and 2 532 are staggered, which can not only increase the contact area with the quicksand, but also improve the bite force with the quicksand. At the same time, the openings of the troughs 1 5312 and 2 5322 are all arranged upward. In the subsequent irrigation process, the irrigation water can smoothly enter the troughs 1 5312 and 2 5322 and accelerate the dissolution of the granular fertilizer therein. After long-term planting, as the sand barrier 1 and sand barrier 2 2 including the packaging bags of the quicksand are degraded, the positioning and lifting assembly 5 can be taken out of the quicksand, and the adjusting rings 545 are rotated in the opposite direction to make the multiple arc blocks 2 532 and the multiple arc blocks 1 531 rotate synchronously. As the arc blocks 2 532 and the arc blocks 1 531 rotate, they become loose with the surrounding quicksand. At the same time, the plant roots entangled thereon can be torn off during the rotation of the arc blocks 2 532 and the arc blocks 1 531. At the same time, the roots at the angle between the arc blocks 1 531 and the arc blocks 2 532 can be cut off by the adjacent blade edges 2 5315 and the blade edges 3 5324 at the intersection of the rotation of the arc blocks 1 531 and the arc blocks 2 532. After that, without the entanglement of the plant roots, the positioning and lifting assembly 5 can be easily taken out of the loose quicksand.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
