Technical Field
[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seeder chassis capable of screening crops for sowing. Background Art
[0002] A seeder is a planting machine that sows crop seeds. It is used for a certain type of crop and is often named after the crop type, such as grain drills, corn hole seeders, cotton seeders, forage spreaders, etc. With the continuous development of science and technology, farmers use more mechanized sowing equipment.
[0003] However, during sowing, some existing seeder chassis have damaged seeds or small-particle seeds with low yield rate. The implantation of low-yield seeds is likely to affect the yield and quality of crops in the later stage. While the agricultural machinery is working forward, the sowing machine behind it is very likely to be blocked inside the seeder due to damaged seeds. In this way, the agricultural machinery is still moving forward but the seeds are not sown, thus affecting the harvest of crops. Utility Model Content

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] A seeder chassis capable of screening crops for sowing, such as Figure 1-4As shown, it includes a seeding box 1, fixed plates 13 are fixedly installed at both ends of the seeding box 1, and a roller screen drum 10 is movably installed on one side of the fixed plate 13, a seeder 14 is fixedly installed on one end of the fixed plate 13, and an implantation tube 18 is fixedly installed on one end of the seeder 14, a long-axis spiral plate 17 is fixedly installed on the inner side of the roller screen drum 10, and a second pulley 6 is fixedly installed on one end of the long-axis spiral plate 17, a turntable 15 is fixedly installed on one end of the long-axis spiral plate 17, and a placement hole 16 is opened on the side of the turntable 15, and the air compressor 4 is driven by the motor 3, so that the first pulley 5 rotates through the belt transmission second pulley 6, thereby rotating the roller screen drum 10 and screening the seeds. At the same time, the seeds move toward the end of the seeder 14 under the action of the long-axis spiral plate 17. At this time, the motor 3 drives the fan 8 to rotate at a high speed, so that one side of the turntable 15 inside the seeder 14 generates an adsorption pressure, and the seeds in the seeder 14 are adsorbed on the placement holes 16 on the side of the turntable 15.
[0027] See also Figure 2 A motor 3 is fixedly installed at one end of the seeding box 1, and an air compressor 4 is movably installed at the output end of the motor 3. A fan 8 is movably installed at one end inside the air compressor 4. By installing the fan 8, the fan 8 rotates at a high speed under the drive of the motor 3, so that an adsorption pressure is generated on one side of the turntable 15 inside the seeder 14, and the seeds in the seeder 14 are adsorbed on the placement holes 16 on the side of the turntable 15, which is convenient for picking up and placing the seeds.
[0028] See also Figure 1 A first pulley 5 is fixedly mounted at one end of the fan 8, and the first pulley 5 is connected to the second pulley 6 by a belt. The second pulley 6 is provided in three groups, and the three groups of second pulleys 6 are connected by belts. The transmission power is connected by the belt to provide power for each structure of the device, making the device structure more perfect.
[0029] See also Figure 3 The seeding box 1 is fixedly installed with a funnel groove 11, and a discharge port 12 is opened at one end of the funnel groove 11. By installing the funnel groove 11, the screened seeds are subjected to the action of gravity and the limitation of the inclined sliding surface of the funnel groove 11, and can be better concentrated and discharged from the discharge port 12, which is convenient for collecting the screened aggregate particles.
[0030] See also Figure 1 A seed placing groove 2 is fixedly installed at one end of the sowing box 1, and a material box 7 is fixedly installed at one end of the funnel groove 11. By installing the material box 7, the unqualified seeds screened out are uniformly discharged into the material box 7 from the discharge port 12 for collection, which is convenient for the staff to use, improves work efficiency, and reduces the work intensity of the staff to a certain extent.
[0031] See also Figure 4A pipe 9 is fixedly installed at one end of the air compressor 4, and a through hole is opened on the surface of the roller screen drum 10. By installing the pipe 9, the adsorption pressure generated by the air compressor 4 is evenly distributed to each group of seeders 14 in the device, making the device structure more perfect.
[0032] The working principle of the utility model is as follows: when in use, according to the specifications of sowing seeds, a suitable roller screen drum 10 is installed, and then the motor 3 is started to pour the seeds into the seed placement groove 2. At this time, the seeds will enter the roller screen drum 10 from the seed placement groove 2, and the air compressor 4 is driven by the motor 3 to make the first pulley 5 rotate through the belt transmission second pulley 6, so that the roller screen drum 10 rotates and the seeds are screened. At the same time, the seeds move toward the end of the seeder 14 under the action of the long-axis spiral plate 17. At this time, the motor 3 drives the fan 8 to rotate at a high speed, so that the one side of the turntable 15 inside the seeder 14 generates an adsorption pressure, and the seeds in the seeder 14 are adsorbed on the placement holes 16 on the side of the turntable 15, and rotate synchronously with the roller screen drum 10. The qualified seeds adsorbed on the placement holes 16 are transmitted to the sowing machine behind them through the implantation tube 18. The broken seeds and the seeds with low small particle yield after screening fall on the surface of the funnel groove 11 under the action of gravity, and will be uniformly discharged into the material box 7 from the discharge port 12 for collection.
