Description

Technical Field

[0001] The invention relates to the technical field of planting machinery, and in particular to a grooved roller type precision stem seed metering device. Background Art

[0002] King bamboo grass is a perennial upright clump of grass, also known as grain bamboo grass, king grass, royal bamboo, giant elephant grass, sugarcane grass, with strong tillering ability, a single plant can tiller 80 to 90 plants per year, can be called the emperor of grass. Because of its long leaves and high stems, and the shape of the stems is like a small spotted bamboo, it is named King bamboo grass. King bamboo grass is a hybrid of elephant grass and American foxtail grass, and is a new type of high-efficiency economic crop. It can be planted in most parts of the country, especially in the barren mountains and river basins in the middle and upper reaches of the Yangtze River. The specific requirements are more than 1000 hours of sunshine, 200 to 1500m above sea level, an annual average temperature of more than 15℃, an annual rainfall of more than 1000mm, an annual frost-free period of about 250 days, sufficient water during the seedling period, and deep and fertile sandy soil or loam. It has strong drought resistance and weak waterlogging resistance. It can withstand low temperatures and slight frost, but not freezing. It responds quickly to soil fertility, and cow dung is the best fertilizer. King bamboo grass mainly reproduces asexually, and can reproduce with buds as long as there are nodes with buds. The main uses of King bamboo grass include animal fodder, control of malignant weeds, environmental protection, soil and water conservation, building materials, frame materials, fungus materials, beverages, fuel, pulp materials, etc.

[0003] King bamboo grass is an asexually propagated herb, and is mainly planted by short-stem cuttings. In the planting and production process of King bamboo grass, orderly seeding and sowing is the most critical and basic production link. Due to the large difference in diameter between individual nodes of King bamboo grass, the nodes have a certain curvature, and the planting agronomy requires that 1 to 2 nodes be retained in each node, and each node should have an axillary bud. Axillary buds cause the unique plant physical characteristics of King bamboo grass nodes with different axial diameters. When using existing seeders to seed King bamboo grass, it is easy to cause the seeder to get stuck, blocked, and unable to effectively fill the seeds during the seeding process, which in turn causes problems such as missed sowing, repeated sowing, low germination rate, and poor growth of buds in the sowing process of King bamboo grass, which seriously hinders the research and development of mechanized planting technology and equipment for King bamboo grass and its large-scale promotion and application.

[0044] The seed protection component 4 is arranged in the seed box to protect the seed material and reduce the damage to the axillary buds caused by rolling of the seed material during the seeding process. Figure 8 As shown, the seed protection assembly 4 is composed of a seed protection belt 4.1, a seed protection roller 4.2, a seed protection bracket 4.3 and a pin shaft 4.4. The seed protection bracket 4.3 is provided with an axle pin hole 4.31. The seed protection roller 4.2 is rotatably installed in the axle pin hole 4.31 through the pin shaft 4.4. The seed protection belt 4.1 is installed on the seed protection roller 4.2, so that the seed protection belt 4.1 can rotate around the seed protection bracket 4.3. In this embodiment, the number of seed protection rollers 4.2 is 4. Figure 2As shown, the seed protection belt 4.1 is arranged on one side of the seeding wheel 7 in the vertical direction and is closely attached to the outer peripheral wall of the seeding wheel 7 and can rotate synchronously with the seeding wheel 7. The seed protection belt 4.1 is made of elastic material, so that it can be closely attached to the outer peripheral wall of the seeding wheel 7 without damaging the objects to be planted. In this embodiment, the upper end of the seed protection belt 4.1 is arranged close to the seed cleaning brush 3.2, and the lower end is arranged close to the flip plate 5.3, so that when the objects to be planted rotate from the upper end to the lower end with the seeding wheel 7, the protection of the seed protection belt 4.1 can reduce the rolling of the objects to be planted during the seeding process, thereby reducing the damage to the axillary buds of the objects to be planted.

[0045] like Fig. 9 As shown, the seeding box 5 is composed of a seeding box positioning plate 5.1, a seeding box rear support plate 5.2, a flip plate 5.3, a seeding box right support plate 5.4, a seeding box front support plate 5.5 and a seeding box left support plate 5.6. The seeding box positioning plate 5.1 is installed on the upper part of each support plate, and the seeding box positioning plate 5.1 is provided with a bolt hole 5.12 for connecting with the seeding box 1, and the seeding box positioning plate 5.1 is also provided with a bearing seat mounting hole 5.11 for mounting the transmission mechanism 8. The flip plate 5.3 is arranged at the bottom opening of the seed box 5, and its function is to flip the objects to be planted, such as king grass, from a horizontal state to a vertical state, and is fixedly installed on the rear support plate 5.2 of the seed box. In this embodiment, the flip plate 5.3 is fixedly installed on the rear support plate 5.2 of the seed box, and the length and width of the flip plate 5.3 are both smaller than the opening at the bottom of the seed box 5, that is, the flip plate 5.3 can only partially block the bottom opening of the seed box 5, so that the objects to be planted in the seed box 5 can be discharged from the unblocked bottom opening of the seed box 5 and fall into the seed guide groove 6; in order to flip the objects to be planted from a horizontal state to a vertical state, the width of the flip plate 5.3 should be at least less than half of the length of the seed groove 7.3, or less than the objects to be planted. The turning plate 5.3 is one-half of the length, so that when the objects to be planted in the seeding groove 7.3 rotate to the opening at the bottom of the seeding box 5 with the seeding wheel 7, the turning plate 5.3 can partially block the opening at the bottom of the seeding box 5, so that one end of the objects to be planted is supported by the turning plate 5.3 and the other end is suspended. Since the length of the suspended end of the objects to be planted is greater than the length of the supporting end, the suspended end falls downward due to the action of gravity, and the objects to be planted are flipped from the horizontal direction to the vertical direction and fall into the seed guide groove 6; in this embodiment, the width of the turning plate 5.3 gradually decreases from the end close to the seed protection component 4 to the end away from the seed protection component 4, and the width of the turning plate 5.3 at the smallest point is less than the width of the bottom opening of the turning plate 5.3, and is less than one-half of the length of the seeding groove 7.3.

[0046] The seed guide 6 is installed below the seed box 5 to guide the seed nodes of the king grass discharged from the seed box 5 into the already opened planting ditch to complete the planting of the king grass. Fig.10As shown, the seed guide trough 6 includes a seed guide straight plate 6.1, a seed guide front support plate 6.2 and a seed guide inclined plate 6.3 connected in sequence, the upper ends of the seed guide straight plate 6.1, the seed guide front support plate 6.2 and the seed guide inclined plate 6.3 are all connected to the seed box 5, and the width of the opening of the seed guide trough 6 gradually decreases from top to bottom.

[0047] The method of using the seeding device in this embodiment is: place the object to be planted, such as the seed node of King bamboo grass, horizontally into the seeding box 1, and input power by rotating the power input shaft 8.2, so that the seeding wheel 7 can rotate along with the power input shaft 8.2. At the same time, through the transmission action of the transmission mechanism 8, the seed cleaning brush 3.2 can also rotate synchronously with the brush transmission shaft 3.1, and the seeding wheel 7 and the seed cleaning brush 3.2 start to work. As the seeding wheel 7 rotates, the objects to be planted in the seeding box 1 are pushed into the seeding groove 7.3 by their own gravity and the wavy outer wall of the seeding wheel 7. The excess disordered objects to be planted are cleaned by the seed cleaning brush 3.2 and enter the seeding groove 7.3 in an orderly manner again; the objects to be planted in the seeding groove 7.3 rotate synchronously with the seeding wheel 7, and at the same time, the seed protection belt 4.1 also rotates synchronously with the seeding wheel 7 under the push of the seeding wheel 7, and is always in close contact with the outer peripheral wall of the seeding wheel 7, so that in the process of the objects to be planted rotating from the upper end of the seeding wheel 7 to the lower end and entering the seeding box 5, the seed protection belt 4.1 is The protective effect reduces the rolling of the objects to be planted in the seeding groove 7.3, thereby reducing the damage to the objects to be planted; the objects to be planted that enter the seeding box 5 fall off from the seeding groove 7.3 under the action of gravity and fall on the flip plate 5.3. One end of the object to be planted is supported by the flip plate 5.3 and the other end is suspended. Since the length of the suspended end of the object to be planted is greater than the length of the supporting end, the suspended end falls downward under the action of gravity, causing the object to be planted to flip from a horizontal state to a vertical state and fall into the seed guide groove 6. The vertical state of the king bamboo grass seed node leaves the king bamboo grass seeding device through the seed guide groove 6, thereby realizing the orderly planting of the king bamboo grass.
