AI Technical Summary
The northern grassland areas have drought and rainy rain, frequent wind and sand, which leads to degradation and desertification of grasslands. Natural grasslands rely on natural growth for a long time. The proportion of land productivity, grass survival rate and high-quality grasslands are low, which affects the efficiency of grasslands. The existing technology is difficult to effectively solve the problems of grasslands being blown away by the wind and soil erosion after sowing.
A desert grass-rooting grass pit planter is developed. By rolling on the grass, forming trenches and digging small grass pits in the middle of the trenches, seeds are sown into the grass pit during sowing, and rainwater is accumulated in the grass pit and wind-blown seeds are intercepted to create favorable conditions for grass seeds to grow.
Effectively prevent grass seeds from being blown away by the wind and accumulate rainwater, improve the success rate of grass seed growth, improve the productivity and benefits of grasslands, and alleviate the threat of grassland degradation and desertification.

Abstract
Description
Technical Field
[0001] The utility model relates to a seeder, in particular to a desert grassland rolling grass pit seeder. Background Art
[0002] The northern grasslands are dry, with few surface rivers and no conditions for grassland irrigation. In particular, in late May, when it is the time to sow grass, there are more winds and less rain, and rainwater easily forms runoff, causing soil erosion, which is not conducive to plant growth. Due to overgrazing, the grass becomes sparse and short, with a height of 2-10cm, a coverage of 30%, and a grass yield of 546.8kg / hm2. 2 . Drought, little rain, frequent sandstorms, strong evaporation, and an average annual precipitation of less than 300 mm, coupled with overgrazing, indiscriminate reclamation and digging, have caused grassland degradation, desertification, and a decrease in vegetation coverage. On the one hand, natural grasslands are overwhelmed, exacerbating the threat of grassland degradation and desertification; on the other hand, since natural grasslands have long relied on natural growth, land productivity, grass survival rate, and the proportion of high-quality grass are all low, which directly affects the benefits of natural grasslands. Although a lot of labor and material resources are invested every year to reseed and improve grasslands, the effect is minimal.
[0003] How to store limited rainwater and prevent the sown grass seeds from being blown away by the wind? After years of observation and research, it is found that the uneven surface can not only store rainwater, but also intercept some seeds to prevent them from being blown away by the wind. When the rainy season comes, these seeds will gradually germinate, take root and grow. Therefore, it is necessary to develop a machine that first rolls a groove on the grass, digs a small grass pit in the middle, and then sows seeds in the pit. Utility Model Content
[0004] The utility model aims to provide a desert grassland rolling grass pit seeder, which can roll the grassland into grooves before sowing, dig a small grass pit in the middle, and then sow forage grass seeds in the grass pit, so that the seeds are close to the dark and moist pit bottom under the surface to prevent the wind from blowing the seeds away.
[0005] The purpose of the desert grassland rolling grass pit seeding machine is achieved by the following structure: the seeding machine structure includes a wheel shaft, a load-bearing bracket, a suspension frame, a rolling wheel mechanism, a support frame, and a column support frame. The load-bearing bracket is welded above the wheel shaft through the column support frame, and its function is to bear the weight and counterweight so as to change the pressure of the rolling wheel on the grass.
[0006] The rolling wheel mechanism is mounted on the wheel shaft through the wheel hub and the wheel hub fixing bolts, and the distance on the wheel shaft can be changed to change the sowing row spacing according to the requirements of agricultural technology and farming;
[0007] The rolling wheel mechanism comprises a rolling wheel, an outer edge of the rolling wheel, pit digging teeth, a grass seed limiting baffle, and a grass seed adding hopper.
[0008] The rolling wheel disc and the outer edge of the rolling wheel disc are welded to each other, and a hollow chamber is formed inside to form a grass seed box for containing grass seeds.
[0009] The digging teeth are triangular in shape and are evenly welded on the outer edge of the rolling wheel in radial distribution. Their function is to dig small grass pits with equal distances on the grass. The convex surface of the digging teeth faces the forward direction. The advantage is that when the digging teeth are unearthed, they compact the pit wall. A discharge port is processed on the outer edge of the rolling wheel corresponding to the concave part of the digging teeth, and a fastening bolt is vertically welded next to the discharge port.
[0010] The grass seed limit baffle is installed on the fastening bolt through a fastening nut. Different sized holes are processed at the four corners of the grass seed limit baffle, and its function is to change the positions of different holes and discharge ports according to grass seeds of different sizes and specifications when sowing grass seeds, so as to limit the sowing amount of grass seeds.
[0011] When the rolling wheel is in operation, grooves of different depths can be pressed on the ground according to the load-bearing weight of the load-bearing bracket, and then the digging teeth dig small grass pits in the middle of the grooves. The advantage is that the grass seeds sown in the grass pits can be shielded from wind and rainwater can be accumulated.
[0012] The grass seed adding hopper is installed on one side of the rolling wheel through a pin shaft and can swing left and right around the pin shaft. Its function is to fill grass seeds into the grass seed box inside the rolling wheel. When adding grass seeds, the grass seed adding hopper is pulled out, and when sowing, the grass seed adding hopper is pushed in around the pin shaft to prevent the grass seeds from leaking out.
[0013] The characteristics of this desert grassland rolling grass pit seeder are that when the rolling wheel rolls on the grass, under the pressure of the machine weight and the counterweight, an indentation is pressed on the ground, and a small grass pit is dug at the bottom of the middle, which can prevent the grass seeds in the pit from being blown away by the wind and accumulate rainwater to create favorable conditions for the growth of grass seeds, effectively solving the problem of water shortage for grass seed growth on desert grasslands. This seeder has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
