Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Global climate change, especially desertification, is one of the most severe crises facing humanity, with its negative impacts on economic development, social stability, and the ecological environment. Planting vegetation in deserts plays a crucial role in improving the desert ecosystem and preventing desertification, including sand fixation, water regulation, providing habitat, improving air quality, and soil remediation.

[0025] However, existing sowing methods have the following problems: manual planting is inefficient and increases the workload of the planting team. Seed survival rate is low in desert environments.

[0026] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-5 A detailed description of the auxiliary seeding equipment is provided.

[0027] To address the aforementioned technical problems, this application provides an auxiliary sowing device that can assist workers in planting in desert areas, reduce the workload of manual sowing, improve seed survival rate, and improve the ecological environment of desert areas.

[0028] This application provides an auxiliary seeding device, comprising: a feeding component 1, having a feeding hole and a discharging hole; a water supply component 2, having a central hole formed along the periphery of the feeding component 1, the central axis of which coincides with the central axis of the discharging hole, and a water outlet pipe 21, the water outlet pipe 21 being connected to the end of the water supply component 2 forming the central hole, the side wall of the water outlet pipe 21 having a water outlet channel 211 and a water outlet hole 212; an elastic transmission component 3, including an elastic component 31 and a contacting component 32, the elastic component 31 being sleeved and confined within the water outlet pipe 21, the elastic component 31 being fixedly connected to the contacting component 32, one end of the contacting component 32 being used to block the water outlet hole 212, and the other end of the contacting component 32 being used to contact the ground; and a rolling component 5, extending from the discharging hole into the interior of the water outlet pipe 21, supported by the feeding component 1 and the water supply component 2, and fixedly connected to the contacting component 32.

[0029] Specifically, the auxiliary sowing equipment includes a feeding component 1, a water supply component 2, an elastic transmission component 3, and a rolling component 5. The feeding component 1 is provided with a feeding hole for seed placement and output. The water supply component 2 is arranged around the periphery of the feeding component 1, forming a central hole. The central hole and the discharge hole have their central axes coincident, and a water outlet pipe 21 is provided. The water outlet pipe 21 is connected to the end of the water supply component 2 that forms the central hole. The side wall of the water outlet pipe is provided with a water outlet channel and a water outlet hole, ensuring that while the seeds can be sown in the area of ​​the soil corresponding to the water outlet pipe 21, water can be accurately placed through the water outlet pipe 21. This design helps the seeds obtain an appropriate amount of water during sowing, improving the germination rate and growth quality of the seeds. The elastic transmission component 3 includes an elastic component 31 and a contact component 32. The elastic component 31 is sleeved on the water outlet pipe 21 and connected to the contact component 32. When the contact component 32 is in contact with the ground, the ground exerts pressure on the contact component 32, and the contact component 32 pushes the elastic component 31 to move, thereby displacing the contact component 32 and exposing the water outlet 212. Water from the water supply component 2 enters the water outlet 212 through the water supply channel and flows out from the water outlet 212 onto the ground. When the contact component 32 is no longer in contact with the ground, it can block the water outlet 212, thereby controlling the water output. The design of the elastic transmission component 3 and the contact component 32 enables precise control of the opening and closing of the water outlet 212, ensuring that an appropriate amount of water is provided each time sowing, avoiding the problem of too much or too little water, and realizing dynamic adjustment of water output. The rolling component 5 is located inside the feed hole and the water outlet pipe 21, connected to the feed component 1 and the water supply component 2, and connected to the contact component 32. The contact component 32 generates displacement to drive the rolling component 5 to move, thereby driving the continuous input of seeds, improving sowing efficiency, and reducing the complexity of manual operation.

[0030] Furthermore, the water supply component 2 includes a water tank 22 and a water outlet pipe 21. The water tank 22 is arranged circumferentially along the feed component 1, and has a central hole. The feed component 1 is located in the central hole. The water tank 22 is connected to the water outlet pipe 21, which is cylindrical. The central axis of the water outlet pipe 21 coincides with the central axis of the central hole of the water tank 22. A water outlet channel 211 is provided on the wall of the water outlet pipe 21, extending axially in the water outlet pipe 21. Retaining rings are provided at both ends of the water outlet pipe 21 in the axial direction to limit the elastic component 31 and prevent it from falling out of the water outlet pipe 21. A portion of the contact component 32 is welded to the elastic component 31, thereby fixing the contact component 32 and the elastic component 31 together.

[0031] In some optional embodiments, a sand-proof component 4 is also included, which is disposed at the end of the water outlet pipe 21 away from the water supply component 2.

[0032] Specifically, during the sowing process, especially outdoors or in environments with poor soil conditions, impurities such as sand and pebbles can easily mix into the water flow, potentially clogging the water outlet 212 or affecting normal seed sowing. The sand-proof component 4 effectively prevents these impurities from entering the water outlet 21, ensuring clean water flow and successful seed sowing. The sand-proof component 4 acts as a barrier, reducing the risk of damage to these components due to impurity intrusion, thereby extending the equipment's lifespan. The presence of impurities can affect the even distribution of seeds and sowing depth, thus impacting crop growth and yield. By preventing impurities from entering, the sand-proof component 4 helps maintain the stability and accuracy of the sowing process, improving sowing precision. If excessive impurities accumulate inside the water inlet pipe, frequent maintenance and cleaning may be required. The sand-proof component 4 reduces the likelihood of impurities entering, thereby reducing the frequency and difficulty of maintenance and cleaning, and improving the ease of use and reliability of the equipment.

[0033] In some optional embodiments, the sand-proof component 4 includes a discharge element 41 and a sand-proof component 42. One end of the discharge element 41 is connected to the end of the water outlet pipe 21 away from the water outlet pipe 21, and the other end of the discharge element 41 is rotatably connected to the sand-proof component 42.

[0034] Furthermore, the discharge element 41 is connected to one end of the water outlet pipe 21, ensuring that water flows smoothly and unobstructed to the sowing area. The anti-sand element 42 is rotatably connected to the other end of the discharge element 41. When the contact part 32 contacts the ground, the ground exerts pressure on the contact part 32, causing the anti-sand element 42 to rotate or swing relative to the discharge element 41 to a certain extent. This flexibility helps the anti-sand element 42 to more effectively block sand and impurities from different directions, improving the overall sand-proof capability. Because the anti-sand element 42 can rotate, it can automatically adjust its position when encountering larger impurities or sand clumps, preventing these impurities from directly clogging the discharge port. This adaptive mechanism reduces equipment failures and downtime caused by blockages, improving the stability and reliability of the equipment. The separate design of the discharge element 41 and the anti-sand element 42 makes cleaning and maintenance easier. When the equipment needs cleaning, the anti-sand element 42 can be easily disassembled for cleaning without disassembling the entire water outlet pipe 21, reducing maintenance costs and time and improving the ease of use of the equipment.

[0035] In some optional embodiments, the discharge element 41 is frustum-shaped, with the larger diameter end of the discharge element 41 connected to the water outlet pipe 21, and the smaller diameter end of the discharge element 41 rotatably connected to the sand-proof element 42.

[0036] Specifically, the frustum-shaped discharge element 41, when connected to the water outlet pipe 21 and the sand-proof element 42, forms a gradually narrowing channel. This helps accelerate the seed flow, allowing seeds to reach the sowing area more quickly after leaving the water outlet pipe 21. It also helps concentrate water in the sowing area, ensuring seeds receive adequate moisture, promoting germination and growth, and preventing water from spilling outside the sowing area. Furthermore, the increased water flow speed helps flush away sand and impurities adhering to the outer surface of the discharge element 41, reducing the risk of clogging. The frustum-shaped design of the discharge element 41 allows its smaller diameter end to connect with the sand-proof element 42, limiting the space for sand and impurities to enter the sand-proof element 42, thus enhancing its sand-proofing effect. In addition, the accelerated water flow as it passes through the discharge element 41 also helps prevent sand and impurities from entering the sowing area. The frustum-shaped discharge element 41 forms a stable support structure when connecting the water outlet pipe 21 and the sand-proof element 42, which helps to enhance the stability and durability of the entire sand-proof component 4 and ensures that the equipment can maintain stable performance during long-term use.

[0037] In some alternative embodiments, the sand-proof element 42 includes a plurality of blocking elements 421 arranged circumferentially along the port of the discharge element 41, and each blocking element 421 is rotatably connected to the discharge element 41.

[0038] Specifically, multiple blocking elements 421 are arranged circumferentially along the port of the discharge element 41, forming an all-around protective barrier. This effectively blocks sand and impurities from all directions, ensuring that water flows smoothly to the sowing area without being blocked by sand and impurities. Since each blocking element 421 is rotatably connected to the discharge element 41, it can automatically adjust its position when encountering sand and impurities, thus avoiding blockage. This flexibility and adaptability allows the anti-sand element 42 to better adapt to different sowing environments and conditions, improving the stability and reliability of the equipment. The rotatable connection between the blocking elements 421 and the discharge element 41 not only helps prevent the entry of sand and impurities but also optimizes the water flow distribution. When water flows through the discharge element 41, each blocking element 421 automatically adjusts its position according to the pressure and direction of the water flow, ensuring that the water flows out more evenly and reducing soil erosion and washout. Since the blocking elements 421 can rotate, when the blocking elements 421 need to be cleaned, the sand and impurities attached to their surfaces can be removed by rotating these blocking elements 421, which simplifies the cleaning process and improves the ease of use of the equipment.

[0039] In some optional embodiments, the blocking element 421 includes a first blocking rod 4211 and a second blocking rod 4212, which are arranged at a preset angle. One end of the first blocking rod 4211 is connected to the discharge element 41, and the other end of the second blocking rod 4212 is directed toward the central axis of the sand-proof element 42.

[0040] Specifically, the first blocking rod 4211 and the second blocking rod 4212 are set at a preset angle to form a protective structure. This protective structure can more effectively block sand and impurities from different directions, reducing the possibility of them entering the discharge element 41. The other end of the second blocking rod 4212 faces the central axis of the anti-sand-entry element 42. This design helps guide the water flow more smoothly. When the water flows through the discharge element 41, the second blocking rod 4212 can guide the water flow along a preset direction, avoiding direct impact on the soil or unnecessary erosion. One end of the first blocking rod 4211 is connected to the discharge element 41, and the other end of the first blocking rod 4211 is connected to the second blocking rod 4212. The second blocking rod 4212 faces the central axis of the anti-sand-entry element 42, which also enhances the overall structural stability of the anti-sand-entry element 42, making it more robust and durable when facing the impact of sand and impurities. The first blocking rod 4211 and the second blocking rod 4212 are set at a preset angle, which makes the adjustment of the blocking element 421 more flexible. The angle can be adjusted according to changes in the sowing environment and conditions to adapt to different needs.

[0041] In some optional embodiments, the abutment component 32 includes a sealing ring 321, an abutment element 322, and a support element 323. The sealing ring 321 can block the water outlet 212. The support element 323 connects the sealing ring 321 and the abutment element 322. The abutment element 322 is provided with a through hole through which the sand-proof component 4 passes.

[0042] Specifically, the elastic transmission component 3 includes an elastic component 31 and a contact component 32. The elastic component 31 is sleeved on the water outlet pipe 21 and connected to the contact component 32. When the contact component 32 is in contact with the ground, the ground exerts pressure on the contact component 32, and the contact component 32 pushes the elastic component 31 to move, thereby displacing the contact component 32 and exposing the water outlet 212. Water in the water supply component 2 enters the water outlet 212 through the water supply channel and flows out from the water outlet 212 and sprays onto the ground. When the contact component 32 is no longer in contact with the ground, it can block the water outlet 212, thereby controlling the water output. The design of the elastic transmission component 3 and the contact component 32 enables precise control of the opening and closing of the water outlet 212, ensuring that an appropriate amount of water is provided each time sowing, avoiding the problem of too much or too little water, and realizing dynamic adjustment of water output.

[0043] Furthermore, the sealing ring 321 allows the outlet hole 212 to be effectively sealed when needed. The support element 323, as a key component connecting the sealing ring 321 and the contact element 322, enhances the structural stability of the entire contact component 32, helping to ensure that the sealing ring 321 can stably seal the outlet hole 212, while supporting the contact element 322 and its anti-sand-soil component 4. The through-hole on the contact element 322 allows the anti-sand-soil component 4 to pass through, and the water flowing out of the outlet hole 212 flows to the sowing area in the area between the support element 323 and the anti-sand-soil component 42. The contact element 322 is used to contact the ground, increasing the contact area and improving the flexibility of the contact component 32.

[0044] In some optional embodiments, the support element 323 is a cylindrical support wall, which is connected to the sealing ring 321 and the abutment element 322 respectively; or, the support element 323 includes a plurality of support rods, one end of which is arranged circumferentially on the sealing ring 321, and the other end of which is connected to the abutment element 322.

[0045] Specifically, the cylindrical support wall provides a robust connection between the sealing ring 321 and the abutment element 322, enhancing the structural rigidity and stability of the entire abutment component 32. This helps ensure that the sealing ring 321 can stably seal the water outlet 212, preventing displacement or damage caused by water flow impact or other external factors. The cylindrical support wall design is relatively simple, facilitating manufacturing and processing, simplifying the installation process of the abutment component 32, and reducing installation costs and time.

[0046] Multiple support rods are arranged circumferentially around the sealing ring 321, allowing the contact component 32 to better adapt to different working environments and needs. Compared to a cylindrical support wall, the design of multiple support rods is generally lighter, helping to reduce the overall system weight. The gaps formed between the multiple support rods help enhance heat dissipation. A protrusion is provided on the area of ​​the sealing ring 321 facing the water outlet; the protrusion is located on the inner surface of the sealing ring 321 and can penetrate the gaps between the springs to seal the water outlet.

[0047] In some alternative embodiments, the abutment element 322 is a plurality of abutment pieces disposed at the end of the support element 323, and the abutment pieces are circular, elliptical and polygonal in shape.

[0048] Specifically, the contact element 322 is used to make direct contact with the ground. The contact piece is circular, elliptical, or polygonal in shape, which can increase the contact area with the ground. This allows the contact element 322 to better transmit force to the elastic component 31, causing the elastic component 31 to contract and drive the elastic contact component 32 to move, thereby enabling more precise control of the water flow switch.

[0049] In some optional embodiments, the rolling component 5 includes a one-way flywheel 51, a drive chain 52 and a gear 53. The drive chain 52 is connected to the abutting component 32. The drive chain 52 meshes with the one-way flywheel 51 and the gear 53 respectively. The one-way flywheel 51 is connected to the water supply component 2, and the gear 53 is connected to the water supply component 2.

[0050] Specifically, the elastic transmission component 3 includes an elastic component 31 and a contact component 32. The elastic component 31 is sleeved on the water outlet pipe 21 and connected to the contact component 32. When the contact component 32 contacts the ground, the ground exerts pressure on the contact component 32, causing the contact component 32 to push the elastic component 31 to move. During this movement, the contact component 32 drives the transmission chain 52 to move. Through the meshing of the transmission chain 52 with the one-way flywheel 51 and the gear 53, the one-way flywheel 51 is rotated. The one-way flywheel 51 can store energy and release it smoothly when needed. During its rotation, the one-way flywheel 51 drives the seeds in the feeding component downwards, thus smoothly sowing the seeds in the corresponding area and improving the sowing efficiency. The gear 53, as a transmission component, has the characteristics of stable transmission ratio and high transmission accuracy.

[0051] Furthermore, the rolling component 5 also includes a first rotating shaft and a second rotating shaft. The first rotating shaft is fixed to the feeding component 1 and connected to the one-way flywheel 51, thereby fixing the one-way flywheel 51 to the feeding component 1. The second rotating shaft is fixed to the water outlet pipe 21 and is used to connect with the gear 53, thereby fixing the gear 53 to the water outlet pipe 21. One side of the transmission chain 52 is fixedly connected to the sealing ring 321. A groove is provided on the side wall of the water outlet pipe 21, and the groove is arranged along the axial direction of the water outlet pipe 21. One end of the bolt is connected to the sealing ring 321, and the other end passes through the groove and is connected to the transmission chain 52. When the elastic component 31 contracts, the sealing ring 321 will move with the elastic component 31. During the movement of the sealing ring 321, it drives the transmission chain 52 to move, thereby driving the one-way flywheel 51 and the gear 53 to rotate.
