Description

Technical Field

[0001] The present invention relates to the technical field of grass seed sowing machinery, and particularly to a grass seed mixed sowing device for artificial grassland planting. Background Art

[0002] Grass seed mixed sowing is a sowing technique that mixes two or more grass seeds in a certain proportion and sows them. The aim is to combine the advantages of different grass seeds to create a more stable and adaptable grassland. By selecting grass seeds with complementary characteristics, the tolerance, aesthetics, and stress resistance of the grassland are improved, enabling it to maintain a good state under different environmental conditions.

[0003] Publication No.: CN217486927U discloses a grass seed mixed sowing machine for artificial grassland establishment. The lower end of the threaded rod passes through the bearing of the lower movable groove and is fixedly provided with a first driven bevel gear. The rear end of the crank passes through the bearing on the front side wall of the distribution plate and is fixedly provided with a first driving bevel gear. A regulating plate is fixedly provided at the rear side of the nut, and a slider is fixedly provided at the rear side of the regulating plate. The mixed sowing ratio of each grass seed can be adjusted as needed, and the sowing is uniform, avoiding waste of grass seeds, and the practicability is stronger.

[0004] In the related art, at present, the grass seed supplementary sowing of grasslands is mainly divided into two methods: broadcasting and drilling. When the existing grass seed broadcasting equipment is working, some equipment directly broadcasts the grass seeds. However, the grass seeds are light in weight, and under the influence of wind, the dispersion effect of the grass seeds is poor. If the grass seeds are mixed with fine sand and then supplemented and sown through the broadcasting equipment, when the equipment is working, the fine sand will accumulate downward through the gaps between the seeds, causing stratification between the fine sand and the grass seeds, resulting in poor uniformity of the grass seeds after sowing.

[0005] Therefore, it is necessary to provide a grass seed mixed sowing device for artificial grassland planting to solve the above technical problems. Summary of the Invention

[0062] In this embodiment, different from the existing grass - seed sowing equipment, in this case, the grass seeds are fed by the rotation of the screw conveyor rod 23, and during the rotation process, the mixing rod 22 drives the mixing of the grass seeds in the seed box 21. The fine sand is fed by the rotation of the rotating shaft 32. The fine sand and grass seeds will fall on the hybrid impeller 43 through the inclined plane of the mixing box 41, and then the hybrid impeller 43 mixes the fine sand and grass seeds. The mixed grass seeds directly fall on the top of the sowing tray 35 through the discharge pipe 44, and the sowing tray 35 sows the mixed grass seeds. Compared with the existing grass - seed sowing equipment, there is no need to mix the grass seeds and fine sand in advance, reducing the workload of workers. Moreover, when the grass seeds are sown, there will be no layering phenomenon between the fine sand and grass seeds, thus improving the uniformity of the sown grass seeds. And, after the grass seeds and fine sand are mixed, the volume of the grass seeds increases, improving the dispersion effect of the grass seeds.

By loosening the connecting bolt 91, the use height of the connecting frame 92 and the grass raking member 93 can be adjusted, improving the flexibility of the device during operation.

[0081] Please refer to again Figures 1 to 16, the working principle of the grass seed mixed sowing equipment for artificial grassland planting provided by the present invention is as follows:

[0082] Step S1, connect the traction machine through two connecting seats 8, then put two or more kinds of grass seeds into the seed box 21, the traction machine drives the equipment to move forward, and two moving wheels 103 drive the drive shaft 102 to rotate when walking. The rotation of the drive shaft 102 drives the bottom sprocket 104 to rotate, and the rotation of the bottom sprocket 104 drives the top sprocket 104 to rotate through the chain 105. The rotation of the top sprocket 104 drives the two screw conveyors 23 to rotate, and the grass seeds are conveyed inward through the rotation of the screw conveyors 23 and then fall on the inclined surface in the mixing box 41. The rotation of the screw conveyors 23 will drive the bottom transmission wheel 24 to rotate, and the bottom transmission wheel 24 drives the top transmission wheel 24 to rotate through the transmission belt 25. The rotation of the top transmission wheel 24 drives the mixing rod 22 to rotate, so as to mix the seeds in the seed box 21;

[0083] Step S2, start the sowing motor 37, the rotation of the sowing motor 37 drives the rotating shaft 32 to rotate, and the rotation of the rotating shaft 32 further drives the arch-breaking frame 33 and the spiral blade 34 to rotate. Through the rotation of the arch-breaking frame 33, the fine sand in the storage hopper 31 is prevented from arching, and the fine sand in the storage hopper 31 is fed through the rotation of the spiral blade 34. The falling fine sand also falls on the inclined surface in the mixing box 41;

[0084] Start the mixing motor 45, the rotation of the mixing motor 45 drives the mixing shaft 42 to rotate, and the rotation of the mixing shaft 42 drives the mixing impeller 43 to rotate at the same time, so as to mix the fine sand and the grass seeds. The mixed grass seeds will fall on the right front side of the sowing disc 35 through the discharge pipe 44. When the rotating shaft 32 rotates, it will drive the bottom sowing disc 35 to rotate at the same time, and the mixed grass seeds are sown through the rotation of the sowing disc 35;

[0085] Step S3, start the water pump 59, and the water pump 59 pumps the water in the water tank 58 into the spray pipe 55 and sprays the water to the ground where the grass seeds have been sown through the nozzle 57. Start the hydraulic rod 54, and the extension of the hydraulic rod 54 drives the connecting plate 53 and the two gear plates 52 to move backward. The backward movement of the gear plates 52 drives the two gears 56 to rotate, and the rotation of the two gears 56 drives the spray pipe 55 to rotate. Through the reciprocating telescoping of the hydraulic rod 54, the nozzle 57 swings back and forth to spray;

[0086] Step S4: When the hydraulic rod 54 retracts forward to reset, the hydraulic rod 54 drives the connecting plate 53 and the two gear plates 52 to move forward. The two gear plates 52 then drive the two sliding plates 66 to move forward, causing the two rotating wheels 65 to drive the two knocking rods 62 and the knocking blocks 63 to move upward respectively, and causing the spring 64 to contract. By moving the two knocking blocks 63 upward, the bottom of the mixing box 41 is knocked to prevent the grass seeds and fine sand from failing to slide down.

[0087] Step S5: When the equipment moves forward, the grass raking member 93 rakes the withered grass on the ground forward to prevent the grass seeds from being sown on the surface of the withered grass, thereby increasing the contact rate between the grass seeds and the ground. With the arrangement of the dialing plate 14, the grass can be patted to prevent the grass seeds from falling on the grass. With the arrangement of the pressing wheel 16, the grass seeds are pressed into the soil to increase the contact area between the grass seeds and the soil, facilitating the smooth germination and growth of the grass seeds.

[0088] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
