Abstract
Description
Technical Field
[0001] The invention relates to the technical field of air-suction disc seeding, in particular to an air-suction disc seeding device with a material screening mechanism. Background Art
[0002] The pneumatic seeder is a seeder that achieves precision sowing by sucking seeds under negative pressure. Compared with mechanical seeders, its technical performance has great advantages. Precision sowing can achieve single-grain sowing, reduce seed usage, reduce seed costs, and improve sowing precision. After actual field testing, the qualified rate of sowing plant spacing can reach 87%-94%, and the missed sowing rate and reseeding rate are significantly reduced. Generally, the reseeding rate is 8%-12%, and the missed sowing rate is 6%-9%. High-speed sowing can be achieved. However, when the pneumatic seeder is working, the matching tractor not only has to drive the entire seeder to move, but also has to drive the fan to rotate at high speed, which will consume a certain amount of extra fuel.
[0003] Disc seeders are divided into horizontal disc seeders and inclined disc seeders. For horizontal disc seeders, the hole shape on the seed disc is determined by the seed shape, size and required number of grains per hole, and is arranged at a certain spacing. The spacing between plants (holes) is related to the rotation speed and number of holes of the seed disc. Seeders are equipped with seed discs with various slot hole sizes, which can be selected according to the crops, seed size, sowing amount and plant (hole) spacing. This seeder is mainly used for precision sowing of seeds such as corn, sorghum and soybean. The operating speed is generally not more than 6km / h, otherwise the seeding quality will deteriorate significantly. The inclined disc seeder is characterized in that seeding is completed through two processes: filling and discharging. That is, the seeds enter the seed disc through the filling disc and then are discharged into the seed furrow. The seeding height of this seeder is relatively low, which is conducive to improving the uniformity of plant spacing. The inclined configuration of the seeder improves the side of the filling disc hole The air-suction disc seeder has good filling capacity and natural seed clearing capacity, and the damage rate is low. According to the size of the seeds of the crops to be sown, there are a variety of seed filling discs and seed discharge discs for selection. The plant spacing can also be changed by adjusting the transmission ratio. The seed discharger is mainly used for point (hole) sowing of corn, soybeans, beets, vegetables, peanuts and other seeds. The operating speed is relatively low, generally not exceeding 6km / h, and its seed discharge performance is good. The air-suction disc seeder is already a mainstream type of existing sowing equipment, but the existing air-suction disc seeder does not have the screening function when in use, resulting in that only one type of crop seed can be sown during sowing. The seeds can be replaced only after the sowing is completed, and other seeds cannot be flexibly added and sown at the same time as needed. The flexibility is poor and it is not convenient to use. Therefore, an air-suction disc seeder with a screening mechanism is proposed to solve the above problems. Summary of the invention

[0020] The screening mechanism 9 includes a fixed plate 901, a fixed plate 901 is fixedly installed on the left side wall of the connecting box 8, a servo motor 902 is threadedly connected to the inner bottom wall of the fixed plate 901, an output shaft of the servo motor 902 is fixedly connected to a rotating shaft 903, a driving gear 904 is fixedly installed on the outer surface of the rotating shaft 903, a support plate 905 is fixedly installed on the left side wall of the connecting box 8, a mounting cylinder 906 is fixedly installed on the bottom of the unloading box 7, a rotating seat 907 is fixedly installed on the bottom of the mounting cylinder 906, a rotating rod 908 is arranged inside the rotating seat 907, a rotating gear 909 is fixedly installed on the outer surface of the rotating rod 908, a fixed gear ring 910 is arranged inside the rotating seat 907, an adjusting screen cylinder 911 is fixedly installed inside the fixed gear ring 910, a driven gear 912 is fixedly installed on the outer surface of the adjusting screen cylinder 911, and a unloading screen cylinder 913 is arranged inside the adjusting screen cylinder 911. Example
[0021] Through the setting of the disc seeder 1, the equipment can be provided with installation and fixation, the suction cup 3 can be driven to rotate through the driving roller 2, and through the setting of the sowing component 4, the sucked seeds can be sown and discharged in coordination with the rotation of the suction cup 3, and the seeds can be further discharged through the sowing tube 5. The setting of the suction pipe 6 can be connected to the fan, and the suction cup 3 can generate negative pressure through the drive of the fan to absorb the seeds. The setting of the discharge box 7 can directly pour the seeds into it to add materials to the equipment. Example
[0022] By setting the fixed plate 901 and the support plate 905, support and fixation can be provided for the servo motor 902 and the rotating shaft 903. At the same time, the setting of the driving gear 904 can drive the driven gear 912 to rotate at the same time through the meshing relationship, and further drive the adjusting screen drum 911 to rotate at the same time. By setting the rotating rod 908, the rotating gear 909 and the fixed gear ring 910, the adjusting screen drum 911 can rotate normally inside the rotating seat 907. The setting of the mounting cylinder 906 can connect and fix the rotating seat 907 and the discharge box 7.
[0023] When implementing, follow these steps: 1) First, start the fan to make it run, extract the air inside the disc seeder 1 through the suction pipe 6, and make the suction cup 3 generate negative pressure to absorb the seeds, and further cooperate with the sowing component 4 to transport the seeds to the inside of the sowing tube 5; 2) Then the seeds are directly poured into the inside of the feeding box 7. A part of the seeds passing through the feeding box 7 will be screened by the feeding screen cylinder 913, enter the inside of the connecting box 8, and further enter the inside of the sowing tube 5, completing the sowing and feeding; 3) Then the unscreened seeds will directly enter the disc seeder 1 through the feeding box 7, and after being directly sucked by the negative pressure of the suction cup 3, they will enter the sowing tube 5 to complete the sowing and feeding; 4) Finally, when the sieve hole needs to be adjusted, the servo motor 902 is started to make it start rotating, which further drives the rotating shaft 903 to rotate, thereby rotating the driving gear 904, and then drives the driven gear 912 to rotate, and finally the adjusting sieve cylinder 911 follows the rotation. The setting of the rotating rod 908, the rotating gear 909 and the fixed gear ring 910 can provide rotation support for the adjusting sieve cylinder 911 to ensure that it can rotate normally. Finally, the purpose of adjusting the filter aperture is achieved by adjusting the sieve hole misalignment of the sieve cylinder 911 and the unloading sieve cylinder 913.
[0024] In summary, the air-suction disc seeding device with a screening mechanism has the function of screening and sowing through the setting of the screening mechanism 9, and can realize screening and sowing without stopping the machine, further increasing the flexibility of the equipment and effectively improving the sowing efficiency of the equipment. The existing equipment does not have the screening function. When sowing, only one type of seeds can be sown. When sowing is completed, another type of seeds can be replaced for sowing. Two different types of seeds cannot be sown at the same time. The flexibility of use is poor and it is inconvenient to use. The setting of the screening mechanism 9 effectively solves this problem. Through the screening function, the diameters of two different types of seeds are compared and screened, so that the two types of seeds can be quickly replaced for sowing, or sown at the same time. At the same time, screening and adjustment can be performed according to seeds of different sizes, further improving the function of the equipment. Compared with the existing equipment, the use effect is more outstanding and more practical.
