Description

Technical Field

[0001] The invention relates to the technical field of sowing, in particular to a sowing device for desertification ecological restoration. Background Art

[0002] Desertification refers to the severe degradation of land in arid and semi-arid areas, with the surface gradually covered by shifting sand, leading to an imbalance in the ecosystem and a continuous reduction in arable land. By utilizing biological and engineering measures to construct shelterbelts and increase vegetation coverage, windbreaks and sand fixation can be achieved. Traditional afforestation methods primarily rely on manual planting with farm tools such as shovels. This method is inefficient and labor-intensive. Furthermore, water seepage into the sand is severe, and irrigation water seeps into areas where roots cannot extend. This results in high irrigation demands and frequent irrigation, which in turn leads to low plant survival rates, wastes water resources, and increases the cost of ecological restoration of desertified land.

[0003] Therefore, it is necessary to provide a seeding device for desertification ecological restoration to solve the problems raised in the above background technology. Summary of the Invention

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A sowing device for desertification ecological restoration, comprising a sowing frame and a sowing assembly, the sowing assembly comprising a lifting mechanism installed on the sowing frame, a lifting frame installed on the lifting mechanism, a material box installed on the lifting frame, a sowing pipe rotatably installed at the lower end of the material box, a drill pipe installed at the lower end of the sowing pipe, an axial groove provided on the outer wall of the drill pipe, a drilling tool installed on the groove, an annular cavity provided in the pipe wall of the sowing pipe, a column cavity connected to the annular cavity provided in the pipe wall of the drill pipe, a spray hole connected to the column cavity provided on the outer wall of the drill pipe, and a rotating mechanism for regulating the rotation of the sowing pipe, a supply mechanism connected to the annular cavity, and a hammering mechanism for hammering the sowing surface are also respectively installed on the lifting frame.

[0007] As a preferred technical solution of the present invention, the supply mechanism includes a nutrient box installed on a lifting frame, the lower end of the nutrient box is connected to a material guide pipe, the lower end of the material guide pipe is connected to a material guide box, and the other end of the material guide box is also rotatably sleeved on the outside of the pipe wall of the sowing pipe, and the through hole is connected to the box cavity of the material guide box.

[0008] As a preferred technical solution of the present invention, the strip grooves are arranged in multiple groups in a circumferential manner.

[0009] As a preferred technical solution of the present invention, the column cavity is arranged in the drill pipe wall between adjacent grooves.

[0010] As a preferred technical solution of the present invention, the spray holes are arranged in multiple groups along the column cavity direction.

[0011] As a preferred technical solution of the present invention, the drilling tool includes a bar shell installed in the bar groove, and the upper rotating shaft and the lower rotating shaft distributed above and below are respectively rotatably installed in the bar shell, the upper rotating shaft and the lower rotating shaft are connected by a transmission chain, the upper rotating shaft is also installed with a gear, and the lower rotating shaft is also installed with a drill bit, and the upper end of the bar shell is also installed with a micro hydraulic pressure, and the output end of the micro hydraulic pressure is installed with a gear rod meshing with the gear.

[0012] As a preferred technical solution of the present invention, the blade surface of the drill bit is distributed with through holes.

[0013] Compared with the prior art, the present invention provides a seeding device for desertification ecological restoration, which has the following beneficial effects:

[0014] In the present invention, the sowing ground in the desertified ecological area is first hammered by a hammering mechanism, so that the chamfered table hammer block hammers the sowing ground to form a concave chamfered table hammer groove. On the one hand, it is beneficial for moisture to be gathered in the chamfered table hammer groove area, reducing the rate of moisture loss, so that moisture can effectively and timely act on the vicinity of the seeds. On the other hand, in the early stage of seed germination, the short sprouts can be located in the chamfered table hammer groove, reducing the damage of blowing, hitting and scratching of the sprouts by wind and sand on the ground in the desert ecological area, thereby protecting the weak seed sprouts, allowing the sprouts to grow safely, and improving the connection strength between the roots grown from the seeds and the soil.

[0015] In the present invention, the lifting mechanism and the rotating mechanism are used to drive the gear rod, and the micro hydraulic device is used to control the movement of the gear rod, so that the drill bit gradually opens outward, breaks and loosens the soil in the surrounding area near the lower end of the drill pipe, and then the nutrients are sprayed into the broken soil through the supply mechanism. That is to say, after being compacted by the chamfered hammer block, a columnar broken vertical growth channel is first drilled by the drill bit, and then the area near the lower end of the growth channel is broken to form soft soil fragments, which can enable the seeds to grow and germinate. During the germination process, the seed roots will preferentially move toward the soft and broken soil area. At the same time, the soft soil area is more convenient for storing nutrients, further guiding the seed roots to grow and extend around the growth channel, thereby improving the firmness of the seeds growing in the desertification ecological restoration area and repairing the desertification ecological area.

[0030] In this embodiment, the hammering mechanism 7 includes a hydraulic telescopic device 71 installed on the lifting frame 31, and a hammering seat 72 is installed on the output end of the hydraulic telescopic device 71. A chamfered platform hammer block 73 is installed on the outside of the sowing tube 5. The hammering seat 72 is regulated by the hydraulic telescopic device 71 to hammer the sowing ground in the desertified ecological area, so that the chamfered platform hammer block 73 hammers the sowing ground to form a concave chamfered platform hammer groove. On the one hand, it is beneficial to make water gather in the chamfered platform hammer groove area, reduce the water loss rate, and enable water to act effectively and timely near the seeds. On the other hand, it avoids the early stage of seed germination, and the short sprouts can be located in the chamfered platform hammer groove, reducing the damage of wind and sand on the ground in the desert ecological area to the sprouts by blowing, hitting and scratching, thereby protecting the weak seed sprouts and allowing the sprouts to grow safely. As a preferred embodiment, the sowing tube 5 passes through the center of the chamfered platform hammer block 73.

Specifically, the nutrients are controlled by the nutrient box 81 to be introduced into the guide tube 82, and the nutrients in the guide tube 82 flow through the guide box 83, the through hole 511, the annular cavity 51 and the column cavity 522 in turn, and are sprayed into the broken desertified ecological soil in the area around the seeds through the spray hole 523, thereby realizing the precise delivery of nutrients, reducing the waste of nutrient resources, and saving costs.

[0032] In this embodiment, the strip grooves 521 are arranged in a plurality of groups in a circumferential manner. As a preferred embodiment, the strip grooves 521 are arranged in four groups.

[0033] In this embodiment, the column cavity 522 is provided in the wall of the drill pipe 52 between adjacent grooves 521 .

[0034] In this embodiment, the spray holes 523 are arranged in multiple groups along the column cavity 522 .

[0035] In this embodiment, the drilling tool 53 includes a bar housing 531 installed in the bar groove 521, and an upper rotating shaft 532 and a lower rotating shaft 533 are rotatably installed in the bar housing 531. The upper rotating shaft 532 and the lower rotating shaft 533 are connected by a transmission chain 534. A gear 536 is also installed on the upper rotating shaft 532, and a drill 535 is also installed on the lower rotating shaft 533. A micro hydraulic device 538 is also installed on the upper end of the bar housing 531, and a gear rod 537 meshing with the gear 536 is installed on the output end of the micro hydraulic device 538. Specifically, the micro hydraulic device 538 controls The gear rod 537 is controlled to move up and down, the gear rod 537 drives the gear 536 to rotate, the gear 536 drives the upper rotating shaft 532 to rotate, the upper rotating shaft 532 drives the lower rotating shaft 533 to rotate through the transmission chain 534, and the lower rotating shaft 533 drives the drill bit 535 to move closer to or away from the axis of the drill pipe 52, thereby adjusting the inclination angle of the drill bit 535 and the axis of the drill pipe 52, and then the rotation of the sowing tube 5 is controlled by the rotating mechanism 6, so that the multiple groups of drill bits 535 rotate circumferentially, and then the lifting frame 31 is controlled to descend by the lifting mechanism 3, so that the sowing ground in the desertified ecological area can be broken.

[0036] In this embodiment, through holes 5351 are distributed on the blade surface of the drill bit 535 to reduce the resistance of the drill bit 535 during the circumferential rotation when the drill bit 535 breaks the desertified ecological soil.

[0037] In specific implementation, it includes the following steps:

[0038] Step 1: Connect the sowing rack 1 to a traveling mechanism, which drives the sowing rack 1 to travel on the ground of the desertification ecological restoration area, and load the nutrients required for the germination and growth of seeds into the nutrient box 81. When the sowing component 2 travels to the desired sowing position, it stops traveling and starts sowing the desertification ecological area.

[0039] Step 2: The sowing ground in the desertified ecological area is hammered by the hammering mechanism 7, so that the chamfered platform hammer block 73 hammers the sowing ground to form a concave chamfered platform hammer groove. The chamfered platform hammer block 73 stays on the chamfered platform hammer groove, and the soil near the sowing point area is compacted and reinforced by the chamfered platform hammer block 73, which is beneficial to the seed growth process, has a good reinforcement effect on the seed roots, and improves the connection strength between the roots grown from the seeds and the soil;

[0040] Step 3: Through the coordinated control of the rotating mechanism 6 and the lifting mechanism 3, the drill pipe 52 is made to break and drill the center of the chamfered hammer groove until it reaches the required depth;

[0041] Step 4: The lifting mechanism 3 cooperates to drive, the rotating mechanism 6 continues to drive, and the micro hydraulic device 538 controls the movement of the tooth rod 537, so that the drill 535 gradually opens outward, crushing and loosening the soil in the area around the lower end of the drill pipe 52. The opening angle of the drill 535 is controlled by the micro hydraulic device 538 according to the required crushing range. When the drill 535 is opened to the required angle, nutrients are sprayed into the crushed soil through the supply mechanism 8. That is to say, after being compacted by the chamfered hammer block 73, a cylindrical vertical growth channel is first drilled by the drill 535, and then the area near the lower end of the growth channel is crushed to form soft soil particles, which can enable the seeds to grow and germinate. During the germination process, the seed roots preferentially move toward the soft and crushed soil area. At the same time, the soft soil area is more convenient for storing nutrients, further guiding the seed roots to grow and extend around the growth channel, thereby improving the firmness of the seeds growing in the desertification ecological restoration area and repairing the desertification ecological area.

[0042] Step 5: The drill bit 535 is controlled to retract by the micro hydraulic unit 538 until the drill bit 535 is in a vertical state, so that the drill bit 535 can be withdrawn from the soil along with the drill pipe 52, and the seeds are introduced into the sowing pipe 5 through the feed box 4 and enter the lower end of the drill pipe 52;

[0043] Step 6: The sowing tube 5 is moved upward by the lifting mechanism 3 so that the drill 535 is separated from the soil. After the drill 535 is separated from the soil, the drill 535 is controlled by the micro hydraulic device 538 to shrink and take on an inverted cone shape for the next crushing and sowing.
