Description

Seed supply device of rotary drum type seeder

A technical field

A seed supply device of a rotary drum type seeder belongs to agricultural machinery, in particular to a seed supply device on seeding machinery.

Second, background Art

The rotary drum formula seeder on the existing market has spherical shell disseminator, tubaeform shell disseminator, the storehouse rotates intertillage plant seeding and fertilizing machine, flying saucer shape shell disseminator, the tubular seed metering ware, side storehouse formula disseminator etc. (see fig. 1), they during operation, the dress mouth of disseminator and the storage seed position of disseminator are all rotatory along with the casing, when adding the seed, the machine must stop, and because the casing volume is little, the seed of dress is few, it is frequent to add the seed, lead to work efficiency low, in addition, the seeding in-process, the seed volume in the casing is the reducing gradually, it also can change thereupon to play kind of speed, thereby influence the seeding precision.

Third, the invention

A device capable of stably supplying seeds to a rotary-drum seeder is designed to overcome the defects. The specific structure of the seeder is as follows:

a seed supply device of a rotary drum type seeder comprises a seed supply box (1) (see figure 2) and a throttle box (2), wherein the throttle box is a hollow shell and is provided with a rotating shaft mounting hole (3) and a seed outlet (4), the seed supply box is arranged on a rack and fixedly connected with the throttle box, a seed channel is arranged between the seed supply box and the throttle box, the seed channel is communicated with the throttle box, the throttle box extends into the shell (5) from the tail part of the rotary drum type seeder and is hinged with the shell and a rotating shaft (6), a proper gap is arranged between the tail part of the shell and the throttle box, the gap can ensure that the shell and the throttle box can rotate mutually and can not leak seeds, the seed outlet is positioned below the rotating shaft and is inclined towards the rotating direction of the shell and is suspended above the bottom of the shell (see figures 3, 5 and 6), and the rotating shaft is fixedly connected with.

Operation of the seed supply device (see fig. 4, 5, 6):

1. seeds are filled before sowing: the seeds (7) are loaded into the seed supply box, the seeds flow into the throttling box through the channel and then fall into the shell through the seed outlet, and when the seed surface in the shell rises to submerge the seed outlet, the seeds are prevented from flowing out, and the seed supply stops.

2. Sowing is started: the shell is driven by the rotating shaft to rotate slowly in the clockwise direction according to the arrow direction, seeds in the shell are driven by the shell wall to rotate leftwards and upwards, when the surface of the seeds reaches a certain height and is in a state of being high at the left and low at the right, the seeds do not move upwards along the shell wall under the action of gravity, but slide along the shell wall and stay in place, the seed outlet is inclined leftwards, the seed outlet is still submerged by the seeds, and the seeds in the shell still block the seeds in the throttling box and cannot flow out due to the fact that the seeds are static relative to the seed outlet.

3. The seed amount process in the throttle case automatic control casing: along with the rotation of casing, the seed broadcasts to the ground in, and the seed in the casing reduces gradually, and the resistance to the seed outlet reduces, and the seed in the throttling case flows out in the casing thereupon, and the speed of broadcasting the seed in the ground is faster, and the seed in the casing just reduces faster, and the seed outlet exposes more, and the seed in the throttling case flows out also faster, otherwise flows out slower, and this has just guaranteed that there is stable seed volume in the casing.

4.

The seed outlet is inclined towards the rotation direction of the shell, the inclined angle cannot be too small to incline towards the opposite direction, otherwise, the shell is full of seeds, the seeder cannot work normally, and the seeds can leak from a gap between the throttling box and the shell wall or be clamped in the gap to block the seeder. The reason is that if the seed outlet is not inclined but faces to the right lower side, when the seeder works normally, the seeds in the shell are in a state of being high at the left side and low at the right side, the seeds just below the seed outlet are few and can not submerge the seed outlet, or the pressure on the seeds of the seed outlet is small, the resistance is small, the seeds in the throttling box can flow out quickly, the amount of the seeds in the shell is increased quickly, experiments and theories prove that when the amount of the seeds in the shell exceeds 1/3 of the volume of the shell, the shell rotates, the seeds can not slide on the inner wall of the shell and rotate along with the shell, the seeds below the seed outlet are carried away by the shell like staying on a conveying belt, and the seeds in the throttling box continuously flow out to the position below the seed outlet. The seeds are increased within the housing until the entire housing is filled.

5. If the seed outlet is too high above the bottom of the housing, the initial amount of seed in the housing (the amount of seed when loaded) will exceed 1/3 of the housing volume, and as can be seen, the housing will also be filled with seeds.

Detailed description of the preferred embodiments

A seed supply device of a rotary drum type seeder comprises a seed supply box (1) (see figure 2) and a throttle box (2), wherein the throttle box is a hollow shell, a rotating shaft mounting hole (3) is formed in the throttle box, a seed outlet (4) is formed in the seed supply box, the seed supply box is mounted on a rack and fixedly connected with the throttle box, seed channels which are communicated with each other are formed between the throttle box and the throttle box, the throttle box extends into the shell (5) from the tail of the rotary drum type seeder and is hinged with the shell and a rotating shaft (6), a gap of 1 mm is formed between the tail of the shell and the throttle box, the seed outlet is positioned below the rotating shaft, inclines 30 degrees towards the rotating direction of the shell and is suspended above the bottom of the shell (see figures 3, 5 and 6), the distance between the seed supply box and the shell wall is 10.
