Description

Peanut seeder

Technical Field

The invention belongs to the field of agricultural equipment, and particularly relates to a peanut seeder.

Background

Peanuts are main cash crops in China, the planting area is increased year by year due to good planting benefit, the current planting area reaches about 7000 mu, and in the peanut planting process, the workload of the seeding and harvesting links is large, so that the peanuts are the mechanized difficult problem to be solved most urgently. The mechanical sowing is basically realized by the peanut sowing in China, but the problems of poor sowing effect, low efficiency and the like exist, and the main reason for the problems is that the core part of the sowing machine has a plurality of technical problems.

The disseminator is the key core part of seeder, has directly decided the seeding quality, and current peanut disseminator mainly is outer sheave formula disseminator and bucket wheel formula disseminator, under certain speed, the peanut seed relies on self weight, in entering the disseminator main part through advancing the seeding box from the seeding case, because the entering amount is big, in a large amount of seeds are gushed into the seeding cavity together, causes the seed to block up, takes place the seed easily to block up and arrange and can not come out, simultaneously, the inside structure of current disseminator bumps bad peanut seed easily and causes the high phenomenon of breakage rate, can not satisfy peasant's requirement to peanut seeding.

By the design, two discharging particles, single discharging particles or no discharging particles of the seeding screen can be controlled through the adjusting plate, and the seeding screen is suitable for different conditions.

Further, two channel cavities which obliquely downwards reach the pipe orifice are arranged in the seed guide pipe, and each channel cavity is opposite to the particle passing through hole which rotates through the seed outlet. By the design, seeds are conveniently and smoothly discharged from the seed guide tube.

Further, the shell is made of transparent plastic. So designed, the internal condition is convenient to observe, and the problem is discharged in time.

Compared with the prior art, the invention has the beneficial effects that: peanut seeds depend on the weight of the peanut seeds, the peanut seeds enter the main body of the seeder from the seeding box through the seeding box, a large amount of the peanut seeds flow into the seeding cavity together, so that the peanut seeds are jammed, the seeding shaft is utilized to rotate the seeding screen to disturb the peanut seeds, the problem of seed jam is solved, and meanwhile, the transparent shell can observe the internal condition at any time to prevent the jam; the peanut seeds are matched with the seed blocking plate in a sowing sieve, so that the red skin of the peanut seeds is damaged; the seeding quantity can be controlled by adjusting the adjusting plate; the seed guide tube enables the implantation position of seeds to be uniform. The invention has simple structure and convenient maintenance and use.
