Technical Field

[0001] This invention relates to the field of ecological restoration and desertification control, and in particular to a device for collecting the seeds of sand-fixing shrubs such as willow catkins. Background Technology

[0002] Sand willow is an important windbreak and sand-fixing tree species in arid and semi-arid regions. Its seeds are dispersed by the wind after they mature, forming a fluffy, catkin-like seed. Traditional collection methods rely on manual capture using handheld containers or nets, which are inefficient and limited by wind speed and terrain. Summary of the Invention

[0022] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown in the figure, this embodiment discloses a seed collection device for sand-fixing shrubs, including a collector 1, a negative pressure power module 2, a flexible pipe 3, a seed storage box 4, an adjustable base 5, and a support frame 6.

[0024] Collector 1 is made of high-density polyethylene (HDPE), which is wind-resistant, lightweight (approximately 0.5 kg per cover), and transparent. Collector 1 is trumpet-shaped, with a larger opening at the front (collection port 101) and a smaller opening at the rear (seed discharge port 102). Collection port 101 has a diameter of 80 cm, narrowing to 15 cm at the bottom to connect with flexible pipe 3. Flexible pipe 3 can be made of flexible silicone tubing (2 mm wall thickness), which is resistant to low temperatures (-40℃) and not easily clogged, ensuring that seeds slide smoothly under gravity. The end of flexible pipe 3 connects to seed storage box 4, which is connected to negative pressure power module 2. Through the suction of negative pressure power module 2, seed storage box 4 is created to have a negative pressure environment, thereby collecting seeds through collector 1.

[0025] The surface of collector 1 is covered with a conductive coating (such as a carbon nanotube coating) to prevent electrostatic adsorption of flying fluff. Collector 1 is mounted on an adjusting base 5, which can adjust the horizontal rotation angle and the vertical pitch angle of collector 1. The adjusting base 5 is mounted on a support frame 6.

[0026] like Figure 4 As shown, the structure of the adjusting base 5 includes a rotating base 501, which is rotatably connected to a seat sleeve 502. The seat sleeve 502 is fixed to the top of the support frame 6. Two support ears 503 are provided on both sides of the top of the rotating base 501. A swing base 504 is provided above the rotating base 501. The swing base 504 is connected to the collector. Through holes 505 are provided on the swing base 504 and the support ears 503 on both sides. The swing base 504 is fixed by bolt assembly 506 passing through the through holes 505 on the swing base 504 and the support ears 503.

[0027] In this embodiment, a plug 103 is provided at the bottom of the collector 1, and a socket 507 is provided on the swing seat 504. The plug 103 is plugged into the socket 507. At the same time, a through hole 505 is also provided on the plug 103, and the bolt assembly 506 passes through the through hole 505 on the plug 103.

[0028] In use, the collector 1 rotates around the axis of the bolt assembly 506. When a preset angle is reached, the pitch angle of the collector 1 is fixed by tightening the bolt assembly 506. The support ears 503 on both sides after tightening the bolt assembly 506 can clamp and fix the swing seat 504 in the middle.

[0029] In this embodiment, a first tightening bolt 508 is provided on the seat sleeve 502. After the horizontal rotation angle of the rotating seat 501 is adjusted, the first tightening bolt 508 can be rotated to fix the rotating seat 501. The first tightening bolt 508 is threadedly connected to the seat sleeve 502, and the first tightening bolt 508 and the rotating seat 501 are in abutting engagement.

[0030] like Figure 5 As shown, the support frame 6 can be a tripod telescopic frame. Each leg of the tripod telescopic frame includes an outer cylinder 601 and a support rod 602. The support rod 602 is connected to the outer cylinder 601 through a threaded structure. A second tightening bolt 603 is threadedly connected to the outer cylinder 601. The second tightening bolt 603 can be rotated to fix the support rod 602. The second tightening bolt 603 is threadedly connected to the outer cylinder 601 and is in a pressing fit with the support rod 602.

[0031] In this embodiment, a double-layer dustproof seal 604 is installed at the lower port of the outer cylinder 601. The double-layer dustproof seal 604 includes an outer layer of elastic silicone sand-scraping ring and an inner layer of brush-type dustproof ring, which can automatically remove sand particles adhering to the surface of the rod during adjustment. The surface of the inner rod assembly is provided with multi-start rectangular threads (10mm pitch, 30mm lead), and graphite lubricating strips are embedded in the thread grooves (to reduce wind and sand wear).

[0032] In addition, each leg of the tripod telescopic frame is equipped with ground nails 8 and counterweight sandbags 801 at its bottom to improve the tripod telescopic frame's wind resistance.

[0033] like Figure 6 As shown, the seed storage box 4 is made of transparent acrylic material, allowing observation of the internal seed material interface. The seed storage box 4 consists of a lid and a body, which are secured together by snap fasteners. Inside the seed storage box 4 is a filter screen 7 designed to trap seeds. The filter screen 7 divides the interior of the seed storage box 4 into upper and lower spaces. The space above the filter screen 7 is connected to a flexible pipe 3, i.e., an interface for connection to the flexible pipe 3 is provided on the lid. The space below the filter screen 7 is connected to a negative pressure power module 2, i.e., an interface for connection to the negative pressure power module 2 is provided at the bottom of the body.

[0034] The negative pressure power module 2 is a miniature automatic control centrifugal fan. It is driven by a solar power system 9 mounted on the support frame 6, which supplies power to the negative pressure power module 2. The solar power system 9 mainly consists of solar panels, a controller, and a battery. The battery is electrically connected to the negative pressure power module 2 via a rectifier and voltage regulator, which is used for voltage matching and current control.

[0035] A micro automatic control centrifugal fan powered by a solar power system is added. When it starts in windless weather, the centrifugal fan generates an air pressure difference, creating a suction-enhanced airflow that guides the seeds.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
