Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery and equipment, and in particular to a grass seed reseeding device for optimizing species in degraded pastures and a use method thereof. Background Art

[0002] Grassland degradation refers to the decline of grassland vegetation, which is mainly manifested in the reduction of high-quality forage species, the deterioration of the quality of various forage species, and the decrease in grass yield per unit area. Grassland degradation is a type of land degradation and one of the main manifestations of land desertification. At present, most of the restoration of degraded grasslands adopts near-natural restoration methods such as enclosure, grazing ban, grazing rest, rotational grazing, or artificial restoration methods such as shallow plowing, reseeding, fertilization, rodent control, and insect pest control. Among them, reseeding mainly involves applying fertilizers and sowing forage seeds to the grassland. At present, there is no equipment for reseeding and restoration of degraded grasslands, resulting in low efficiency of reseeding and restoration. In addition, due to the insufficient sowing depth of current sowing equipment, the grass seeds are easily blown away by wind and sand, resulting in poor restoration effect. There is no water replenishment and covering with soil, resulting in a low germination rate of grass seeds.

[0003] Therefore, we have made improvements on this and proposed a grass seed reseeding device and a method for using it for optimizing species in degraded grasslands. Summary of the invention

[0006] As a further solution of the present invention, the chassis includes a steel frame, planting grooves are opened on both sides of the steel frame, and a mounting groove is opened in the middle of the steel frame.

[0007] As a further solution of the present invention, the crawler walking mechanism includes a crawler, a wheel is connected to the middle of the crawler, a first gear is installed on the inner end of the wheel, and the first gear is movably connected to the chassis, and a toothed belt is arranged on the inner side of the crawler.

[0008] As a further solution of the present invention, the punching mechanism includes a roller, a plurality of spikes are evenly arranged on the circumferential surface of the roller, both ends of the roller are rotatably connected to a buffer frame, the upper end of the buffer frame is sleeved on the side of the frame, and the buffer frame is fixedly connected to the frame with a buffer damper.

[0009] As a further solution of the present invention, the switch mechanism includes a fixed frame, which is fixedly connected to the bottom surface of the chassis, and the upper end surface of the fixed frame is slidably connected with a baffle, which is installed on the bottom surface of the sowing turntable, and an electric push rod is connected between the baffle and the fixed frame.

[0010] As a further scheme of the present invention, the sowing mechanism includes two symmetrical grass seed boxes, the upper ends of the two grass seed boxes are simultaneously connected to a feed pipe, the feed pipe is communicated with a storage tank, the bottom end of the grass seed box is rotatably connected to a sowing turntable, a dividing rack is installed inside the sowing turntable, the upper end of the dividing rack is fixed to the grass seed box, a sowing turntable is installed on the outer side of the sowing turntable, and the sowing turntable is engaged with a toothed belt.

[0011] As a further solution of the present invention, a C-shaped guide bar is fixedly connected to the upper end surface of the chassis, and the bottom surface of the guide bar is slidably connected to the upper surface of the transmission component.

[0012] As a further solution of the present invention, the transmission assembly includes two symmetrical conveyor belts, and a drive box is installed for rotation inside the two conveyor belts. A drive shaft is installed at the front end of the drive box, and a third gear is installed at the top end of the drive shaft, and the third gear is meshed with the first gear.

[0013] A method for using a grass seed reseeding device for optimizing species in degraded grasslands, using the above-mentioned grass seed reseeding device for optimizing species in degraded grasslands, comprising the following steps:

[0014] S1. When the device moves on the grassland, the third gear meshes with the first gear, so that the crawler and the conveyor belt maintain synchronous transmission. The bucket installed at the front end of the chassis strips the surface soil of the grassland and sends the stripped soil to the conveyor assembly, which is then transported to the rear end of the device. At the same time, as the chassis moves, the punching mechanism installed at the front end of the bottom of the chassis rolls over the land stripped of soil, and uses the spike cone to poke uniform shallow pits in the soil. After waiting for the sowing mechanism to spread the grass seeds, the soil is evenly divided into several portions and re-covered on the surface of the grassland to cover the soil after the grass seeds are re-sown;

[0015] S2. Fill the storage tank with grass seeds that need to be re-seeded, and the grass seeds fall into the two grass seed boxes through the feed pipe. The device moves at a uniform speed along the path that needs to be re-seeded in the grassland. During the walking process, the crawler track and the wheels are mechanically driven by the motor, so that the toothed belt on the inner side of the crawler track is engaged with the second gear, driving the second gear to rotate. At this time, the baffle is retracted to the inner side of the fixed frame to expose the bottom of the sowing turntable. The second gear drives the sowing turntable to rotate with the movement of the crawler walking mechanism. During the rotation, the grass seeds in the grass seed box are thrown out, evenly dispersed on the grassland surface, and enter the holes punched by the spikes on the grassland to complete the sowing of the grass seeds.

[0016] The present invention provides a grass seed reseeding device for optimizing species in degraded grasslands and a method for using the same, and the beneficial effects are:

[0017] 1. A conveying assembly is installed at the upper end of the chassis, and a bucket is installed at the front end of the chassis. The third gear is meshed with the first gear. The conveyor belt is driven synchronously when the crawler is moving. The bucket strips the surface soil of the grassland and sends the stripped soil to the conveying assembly. The soil is transported to the rear end of the device through the conveying assembly for covering the grass seeds after reseeding, so that the grass seeds can be covered in time after sowing. At the same time, a spike is used to poke uniform shallow pits on the surface of the soil with the surface stripped, so that the grass seeds fall into the shallow pits to prevent the grass seeds from being blown away by the wind and resulting in poor grass seed reseeding effect.

[0018] 2. By installing the sowing mechanism in the middle of the chassis, the sowing turntable is rotatably installed at the bottom of the grass seed box, and the second gear on the outer side of the sowing turntable is meshed with the toothed belt, so that the crawler drives the second gear and the sowing turntable to rotate when walking. When the bottom of the sowing turntable is raised to a certain height from the ground, the second gear and the sowing turntable rotate to throw out the grass seeds in the grass seed box, evenly scatter them on the grass ground, and enter the holes punched by the spikes on the grass to complete the sowing of the grass seeds.

[0019] 3. By installing a dividing rack inside the grass seed box, the bottom surface of the dividing rack is tangent to the sowing turntable, so that the sowing turntable can evenly disperse the grass seeds inside the grass seed box and prevent grass seeds from being blocked when the sowing turntable rotates.
