Rolling type seeder

Abstract

The invention discloses a rolling type seeder. According to the rolling type seeder, a main shaft is provided with a seed disc, a cam shaft and a first separation disc, a second separation disc is arranged on the cam shaft, the portion between the seed disc and the second separation disc is provided with a seed chamber, the portion between the second separation disc and the first separation disc is provided with a cam chamber, a cam fixedly connected to the cam shaft is arranged in the cam chamber, a plurality of arc-shaped main groove bodies are uniformly distributed along the circumference of the cam chamber, the space in each main groove body is provided with a cam bin, the cam bins and the cam chamber form a complete closed space, a seeding module is arranged at a seeding opening of each main groove body, a seed spoon is arranged on the outer wall of each main groove body, the seed spoons are opposite to seed inlets of the seeding modules, a rotatable seed clamp is arranged on thegroove wall of each main groove body, a check ring is arranged on the periphery of the seed chamber, a metal belt with a horizontal convex edge is arranged in the check ring, a seed ring sleeves the outer side of the check ring, the seed spoons are located in the seed ring, the seed ring is divided into a plurality of seed discharging channels by partition plates on the back sides of the seed spoons, and seed shooting holes in the check ring are sequentially opposite to the seed discharging channels correspondingly. The seeder with the structure has the advantages that the row spacing can be conveniently adjusted, seeds with different sizes can be sown, and the seeding precision is high.

Description

technical field [0001] The invention relates to a seeder, and in particular provides a rolling seeder. Background technique [0002] Different crops have different requirements for plant spacing. When adjusting the plant spacing of existing rolling seeders, it is mainly reflected in the number of sowing duck bills installed in the sowing modules around the rolling seeder. The more the number of sowing duck bills, the closer the plant spacing Nearly, the number of sowing duckbills is small, and the distance between plants is farther. Due to the limitation of its overall assembly structure, when adjusting the number of duckbills, it is necessary to disassemble and adjust the roller parts on the entire main shaft, which is very inconvenient to adjust; and because of different The size of the seeds of crops is different, and the seed clips in the existing rolling seeders cannot be used in different sizes, especially when sowing small seeds.

[0002] Different crops have different requirements for plant spacing. When adjusting the plant spacing of existing rolling seeders, it is mainly reflected in the number of sowing duck bills installed in the sowing modules around the rolling seeder. The more the number of sowing duck bills, the closer the plant spacing Nearly, the number of sowing duckbills is small, and the distance between plants is farther. Due to the limitation of its overall assembly structure, when adjusting the number of duckbills, it is necessary to disassemble and adjust the roller parts on the entire main shaft, which is very inconvenient to adjust; and because of different The size of the seeds of crops is different, and the seed clips in the existing rolling seeders cannot be used in different sizes, especially when sowing small seeds. Since the rolling seeders are mostly plastic parts, when the seed clips hold the seeds and rub against the plastic parts At the same time, the static electricity generated by the plastic parts will absorb the light and small particles of seeds, and the seeds cannot be sent into the seed lowering channel well; When two or more seeds are sown, not only the seeds are wasted, but also many seedlings are caused in one pit, which affects the production quality of the crops. It is necessary to use additional labor to pick up the excess seeds, which is a waste of manpower

[0003] And the existing rolling seeder also has the following defects: 1) In order to keep one pit for one kind, one more seed pit is set on the seed clip, but due to the stacking and stacking of seeds in the seed box, the seed clip will not be able to hold the seed when it is clamped once. If the seeds are not held, it will lead to empty sowing, but if multiple seed pits are set, it will lead to multi-sowing. This kind of empty sowing rate due to the structural defects of the rolling seeder is high, and it also requires additional manual control. Replanting empty seed pits is also a waste of manpower

2) The components in the rolling seeder are running internally, and the operator of the rolling seeder cannot directly see the state of the internal seeds, and needs to observe the seed pits one by one, and the work efficiency is low

3) When the existing rolling seeder rolls forward, the seed clip is driven by the lever to rotate and reset by the tension spring, the lever is limited by the limit block, and the cam fixedly connected with the main shaft pushes the lever to overcome the tension of the tension spring to drive The seed clip is opened to hold the seeds. Under this structure, when the rolling seeder is turned upside down, the cam reversely pushes the lever from the direction of the limit block, which will cause the lever to break and cause damage to the rolling seeder.
