Description
Technical Field
[0001] The utility model relates to grass seed sowing, specifically to a grass seed sowing device for mine ecological restoration. Background Technique
[0002] In the crucial field of mine ecological restoration, traditional grass seed sowing methods have always faced many severe challenges. Usually, people will use manual sowing or simple mechanical sowing equipment to carry out the work of sowing grass seeds. However, these methods have a series of deficiencies that cannot be ignored.
[0003] Firstly, manual sowing is undoubtedly an extremely arduous task. Sowing personnel need to bend down and work for a long time, bearing a huge labor intensity. Moreover, the efficiency of manual sowing is extremely low. Facing large-scale mine ecological restoration tasks, it often seems powerless. More importantly, due to the limitations of manual operation, it is difficult to ensure the uniformity and accuracy of sowing. Different sowing personnel may have different operating habits and strengths, resulting in uneven distribution of grass seeds, which has a great adverse impact on the growth of grass seeds and the restoration effect of mine ecology.
[0004] Secondly, existing mechanical sowing equipment also has many problems. On the one hand, these equipment are often bulky, and both transportation and operation are extremely inconvenient. In mining areas, the terrain is complex and changeable, and the roads are rough. Large mechanical sowing equipment is difficult to enter the operation area smoothly. On the other hand, under complex terrain conditions, these equipment are difficult to play their due roles. For example, in areas such as steep slopes and narrow valleys, mechanical sowing equipment may not be able to work properly due to terrain restrictions. In addition, the existing mechanical sowing equipment is not precise enough in controlling the sowing density. Different mine ecological restoration areas have different requirements for the sowing density of grass seeds, and these equipment often cannot be flexibly adjusted according to the actual situation, which makes it difficult to optimize the growth environment of grass seeds, thus affecting the overall effect of mine ecological restoration.
[0005] Therefore, there is an urgent need for a better grass seed sowing device for mine ecological restoration on the market. Content of the Utility Model

[0037] Combined with the accompanying drawings, a grass seed sowing device for mine ecological restoration includes a quadcopter drone body 1; a grass seed sowing mechanism 2 is fixedly provided on the lower side of the quadcopter drone body 1.
[0038] The grass seed sowing mechanism 2 includes a grass seed sowing box body 3. The projection of the upper part of the grass seed sowing box body 3 in the top view direction is rectangular. The two sides of the lower part of the grass seed sowing box body 3 contract inward. The lower part of the grass seed sowing box body 3 is a guiding and feeding chute body 4. The guiding and feeding chute body 4 is inclined. The distance between the guiding and feeding chute body 4 and the upper part of the grass seed sowing box body 3 linearly increases from the rear part to the front part of the guiding and feeding chute body 4.
[0039] A speed reduction motor 5 is fixedly arranged at the rear side of the guiding and feeding chute body 4. An electromagnetic feeding valve 6 is fixedly arranged at the front side of the guiding and feeding chute body 4. The output shaft of the speed reduction motor 5 extends into the guiding and feeding chute body 4. A spiral auger blade 7 is fixedly arranged at the end of the output shaft of the speed reduction motor 5. The spiral auger blade 7 extends towards the direction where the electromagnetic feeding valve 6 is located.

[0041] A storage battery 10 is fixedly arranged at the rear part of the grass seed sowing mechanism 2. A controller 11 is fixedly arranged on the storage battery 10. The controller 11 is electrically connected to the storage battery 10. The controller 11 is electrically connected to the electromagnetic feeding valve 6. The controller 11 is electrically connected to the speed reduction motor 5.
[0042] Support legs 12 are fixedly arranged at the four corners of the lower part of the grass seed sowing box body 3.
[0043] Usage method:
[0044] Grass seed loading:
[0045] Unload the grass seed sowing mechanism 2 from the lower side of the quadcopter drone body 1 and place it on a stable ground to ensure that the support legs 12 stably support the grass seed sowing mechanism 2.
[0046] Open the cover body 9 at the end of the feed pipe body 8 and slowly pour the prepared grass seeds into the grass seed sowing box body 3. Note not to pour in too many grass seeds at one time to avoid clogging.
[0047] After the grass seed loading is completed, cover the cover body 9 to prevent the grass seeds from spilling during transportation and flight.
[0048] Installation and flight:
[0049] Install the grass seed sowing mechanism 2 filled with grass seeds on the lower side of the quadcopter drone body 1 to ensure firm installation.
[0050] Control the takeoff of the quadcopter drone body 1 and fly it to the airspace of the designated mine ecological restoration area. During the flight, pay attention to maintaining the stability and safety of the flight and avoid colliding with obstacles.
[0051] Seeding:
[0052] When the quadcopter drone body 1 flies over the designated area, send a command through the controller 11 to open the electromagnetic blanking valve 6. At this time, the grass seeds begin to flow towards the guiding blanking trough 4 under the action of gravity.
[0053] At the same time, the controller 11 starts the reduction motor 5, and the output shaft of the reduction motor 5 drives the spiral auger blade 7 to rotate. The rotation of the spiral auger blade 7 can, on the one hand, prevent the grass seeds from clogging and ensure the stability of the blanking; on the other hand, it can evenly push the grass seeds towards the electromagnetic blanking valve 6 to ensure the continuity of the blanking.
[0054] Since the lower part of both sides of the grass seed sowing box 3 contracts inward, the distance between the guiding blanking trough 4 and the upper part of the grass seed sowing box 3 linearly increases from the rear part to the front part of the guiding blanking trough 4. This design can ensure that the grass seeds will not accumulate in the grass seed sowing box 3, enabling the grass seeds to smoothly flow towards the electromagnetic blanking valve 6 for seeding.
[0055] End and maintenance:
[0056] After completing the grass seed sowing task, control the quadcopter drone body 1 to return to the landing site.

Check whether each component is damaged or worn, and replace it in a timely manner if necessary. Clean the remaining grass seeds in the grass seed sowing box 3 and the guiding blanking trough 4 to keep the equipment clean for the next use.
[0058] Precisely control the seeding amount:
[0059] The controller 11 in the device can precisely regulate the opening and closing of the electromagnetic blanking valve 6 and the rotation speed of the reduction motor 5. This enables the grass seed blanking amount to be precisely controlled, and can flexibly adjust the seeding density according to different mine ecological restoration areas and grass seed types, thereby effectively improving the survival rate and growth quality of the grass seeds.
[0060] Ensure stable and uniform blanking:
[0061] The setting of the spiral auger blade 7 plays an important role, which ensures the stability and continuity of the blanking. This enables the grass seeds to be evenly sown in the designated area, avoiding the situation of grass seed accumulation or uneven distribution, and laying a foundation for the good growth of the grass seeds.
[0062] Unique design to prevent accumulation:
[0063] The two sides of the lower part of the grass seed sowing box body 3 contract inward, and the distance between the guiding blanking chute body 4 and the upper part of the grass seed sowing box body 3 increases linearly from the rear to the front. This unique design can effectively prevent the accumulation of grass seeds, ensure the smooth flow of grass seeds to the electromagnetic blanking valve 6, and thus ensure the normal operation of the sowing device.
[0064] Efficient and convenient operation:
[0065] By using the quadrotor UAV body 1 to carry the grass seed sowing mechanism 2, it can quickly reach difficult-to-access areas such as mines for grass seed sowing operations. This greatly improves work efficiency and saves a large amount of time and labor costs compared with the traditional manual sowing method. Moreover, when adding materials to the grass seed sowing box body 3, the grass seed sowing mechanism 2 can be easily removed from the lower side of the quadrotor UAV body 1 and fed through the feed pipe body 8, and the operation is very simple and convenient.
