Description

The corn drill seed tray

Technical field:

The utility model relates to the seed tray of the seeder of sower, particularly corn, peanut, soybean, cotton planter.

Background technology:

Present corn (peanut, soybean, cotton) sower, its seeder part exists the even phenomenon of uneven sowing, even causes broadcast leakage owing to design reasons.Both cause the waste of certain seed, and increased workload as filling the gaps with seedlings, pick seedling for again peasant's operation, expended man-hour; Simultaneously, the inhomogeneous growth to crop of sowing is also unfavorable, even causes the underproduction of crop.

Summary of the invention:

The purpose of this utility model is to provide a kind of corn drill seed tray, and it is simple in structure, gets and plants accurately, can avoid the generation of broadcast leakage phenomenon, realizes precision drilling.

The purpose of this utility model realizes by following scheme: the corn drill seed tray, comprise rolling disc, fixed disk and seed-taking device, be characterized in: fixed disk is fixed on the frame, and rolling disc is connected by bearing and axle with fixed disk, and seed-taking device is fixed in and rotates on the web wall.

Seed-taking device of the present utility model by get kind of a box, port, bridge plate, get kind of a wing, box is along constituting.Rotate on the web wall and have mouth, with get kind of a box size and match, box rotates on the web wall along being fixed in by rivet or screw, fixed disk is by the bearing fixing central shaft, rolling disc is fixed on the central shaft, the front lower place of fixed disk is provided with baffle plate, and baffle plate cooperates with rotation web wall, and fixed disk is provided with seed inlet.

The utlity model has following advantage: 1, simple in structure.Its simple for production, long service life; 2, the smart amount of sowing.Owing to get the adjustable of kind of the wing, can realize precision drilling; 3, avoid broadcast leakage.Seed-taking device is reasonable in design, the broadcast leakage phenomenon can not occur.4, applicability is wide.Applicable to sowings such as corn, peanut, soybean, cottons.

Description of drawings:

Fig. 1 is the utility model seed-taking device structural representation; Fig. 2 rotates schematic diagram on the web wall for the utility model seed-taking device is installed on; Fig. 3 is the utility model structural representation.

Embodiment:

Below in conjunction with embodiment utility model is further described:

Embodiment 1: as shown in Figure 1 and Figure 2, seed-taking device by get kind of a box (1-1), port (1-2), bridge plate (1-3), get kind of a wing (1-4), box constitutes along (1-5), get kind of a box front portion and open a port, be used for forwarding from inside to outside seed, the bottom of port (upwards being as the criterion to get kind of a box opening) has a bridge plate, bridge plate to be " J " type, is provided with two at the bridge plate leading section and gets kind of a wing, this moment get kind of a box, port, bridge plate all occupy rolling disc and fixed disk between medium position, get kind of a wing and open to both sides; Get kind of the wing and also can only establish one, get kind of a box, port, bridge plate, get the side that kind of the wing all leans against rolling disc or fixed disk this moment; Getting kind of the wing is long and narrow iron plate, gets kind of a wing angle and can select; As adopt two to get kind of a wing, and the little kind of then getting of angle is many, and angle is greatly then got to plant and is lacked, and can select the 60-160 degree generally speaking.Increase the seed amount of broadcasting as need, then dwindle the angle of getting kind of the wing, available hand shrinks two fins; Reduce the seed amount of broadcasting as need, then enlarge the angle of getting kind of the wing, available hand opens two fins.Kind of a wing is got in adjusting, can realize precision drilling, as the corn of the 1-2 grain that can broadcast.

As shown in Figure 3, seed tray is made up of seed-taking device (1), fixed disk (2), rolling disc (3), and fixed disk, rolling disc are discoid, the related rotation web of rolling disc wall (3-1) (see figure 1), and like this, fixed disk and rolling disc fasten and form disc cassette; Seed-taking device is several, and generally can select 6-12, the best be 8-10, in the practical application, can according to the diameter of the needs selection rolling discs (fixed disk) of broadcasting distance and seed-taking device how much; Rotate the web wall and be provided with some openings with the seed-taking device respective amount, opening with get kind of a box size and match, box rotates on the web wall along being fixed in by rivet or screw (4), like this, gets the inboard that kind of the wing is close to rotation web wall; Fixed disk can be fixed on the frame, also can be fixed on the plough leg (seeder leg) (6) by fixed head (5) as shown in Figure 3, fixed disk has central shaft (7) by bearing fixing, the rolling disc center fixation together rotates rolling disc (rotating the web wall) and seed-taking device on central shaft under the effect of central shaft; Be provided with baffle plate (2-1) in the front lower place of fixed disk, baffle length is slightly larger than rotates 1/4 of web wall, and baffle plate cooperates with rotation web wall, can prevent that seed from falling in advance.

Be provided with seed inlet (2-2) on fixed disk, seed inlet is generally positioned at the position of fixed disk lower middle, and seed inlet leads to seed-box by flexible pipe, and like this, seed can enter seed inlet by flexible pipe by seed-box, and then enters in the seed tray.

Plough pin (8) is fixed on the plough leg by screw, plough bottom bands of trouser legs rear plate (8-1), and like this, seed can be seeded in the clamping plate, thereby prevents that effectively seed from disperseing following sowing time.

Drive mechanism of the present utility model is as follows: an end of land axle is provided with sprocket wheel A, sprocket wheel A by chain drive be located on the frame and with the sprocket wheel B of sprocket wheel A homonymy, sprocket wheel B is located on the power transmission shaft, power transmission shaft is fixed on the frame, the other end of power transmission shaft is provided with sprocket wheel C, sprocket wheel C is by the sprocket wheel D of chain drive homonymy, and sprocket wheel D is fixed on the central shaft.

At seeding time, the rotation of land wheel forms power, the final rotation that drives central shaft, central shaft drives rolling disc (rotating the web wall) and seed-taking device rotates, be in the getting kind of the wing and will begin to get kind of seed-taking device of below, when its rotation is risen, seed will be brought into from inside to outside by port and be got kind of a box; Along with the continuation rotation of rolling disc, seed-taking device begins to descend, and this moment, seed can not fall under the protection of baffle plate; When going to the below,, finish sowing owing to do not have stopping of baffle plate, seed to fall smoothly.Because some seed-taking devices are uniformly distributed on the limit wall of rolling disc,, then can realize continuously getting and plant and sowing like this along with the rotation of rolling disc.

Kind of a box is got in adjustment, can realize the sowing to crops such as corn, peanut, soybean, cottons.
