Abstract

The utility model relates to a unit disc type opener for a seeder, comprising a pull frame. A ditching disc is installed at the lower end of the pull frame. Two conduits are installed on a bear base of the disc. The front conduit is a fertilizer guiding pipe. An opener and a protection plate are connected with the lower end of the fertilizer guiding pipe. The back conduit is a seed guiding pipe. The outer diameter of a circular pipe at the lower end of the seed guiding pipe is sheathed with an anti-clogging cylindrical ditching share. A disc covering shovel is arranged at a certain included angle with the longitudinal centerline of the pull frame. The disc covering shovel can be adjusted in three-dimensional directions. The utility model has the advantages of uniform seeding, a favorable soil penetrating performance and tight seed covering. The utility model can raise the quality of seeding and the yield of crops. The unit disc type opener for a seeder can be used for sandy soil and clay soil. Combined use is available for he unit disc type opener for a seeder, with multiple units parallelly connected.

Description

Sower unit disc type plough

The utility model relates to agricultural tool, a kind of specifically agricultural seeding machine unit disc type plough.

Sower is agriculture widely used agricultural tool, traditional sower, and its kind, a fertile shared conduit, its soil covering implement is a roller, the shortcoming that this facility exist is:

1. kind, fertile mixing mutually when entering soil make seed rotten even rotten easily, influence the growth of crops.

2. kind, fertilizer bury shallow.

3. the depth of burying is irregular.

4. only be applicable to sandy soil, can not be suitable for clay soil.

In order to promote agricultural development, improve agricultural production efficiency and farm output, be necessary to develop the better agricultural seeding machine tool of effect.

The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of unit disc type plough of the agricultural seeding machine that has improved is provided, to plant, fertile conduit branch is arranged, replace the roller covering device with the disc type covering device, reach the raising seeding quality, sow evenly, the depth is even, the earthing performance is good, the purpose that seed viability is high.

The purpose of this utility model is achieved in that

A kind of sower unit disc type plough, its structure comprises tries to stop people from fighting each other, and there is hinged cover the upper end of trying to stop people from fighting each other, the affixed bearing block in lower end of trying to stop people from fighting each other, one trench digging disk is housed in the rotating shaft of this bearing block, and this trench digging disk plane forms an angle with the longitudinal centre line of trying to stop people from fighting each other, and its structure also comprises:

Two conduits, it respectively is hollow circular-tube, vertical ground, at interval suitable distance, parallel trench digging disk is provided with, be fixed on the bearing block of trying to stop people from fighting each other, its forward conduit is a fertilizer guiding tube, the lower end of this fertilizer guiding tube is connected with groove sealing device, this groove sealing device is two poles that bending is backward arranged, at interval suitably apart from the rear side that is fixed in the fertilizer guiding tube cylindrical, this outside, fertilizer guiding tube lower end also is connected with protective plate, this protective plate covers in fertilizer guiding tube outlet and groove sealing device from the side, the front end bending of protective plate is to close trench digging disk card, it is a grain conductor by rear tube, the lower end of this grain conductor is shaped on the imploded arcs limit makes its cross section be hollow heart-shaped opening, be set with anti-blocking tubular ditching plow on the external diameter of this lower end pipe, the matrix of this tubular ditching plow is a circle cover, this circle cover epimere has the opening of suitable height, these opening both sides respectively are connected with clamping plate, be shaped on the screw through hole on the clamping plate, clamp these clamping plate and the tubular ditching plow is fixed on the grain conductor the suitable tangential both sides opening backward that highly is shaped on of the hypomere of described circle cover with bolt and nut;

One covering device, for the disk on sword limit is arranged, its rotating shaft is contained in the bearing block of column lower end, with the longitudinal centre line of the trying to stop people from fighting each other setting that forms an angle, this column is contained in the anchor hub of pillar, becomes height-adjustable connection with dog screw, and this pillar is fixed on the sliding sleeve that is sleeved on the spring pressure beam with the U-shaped screw, but unclamp the extension elongation of U-shaped screw adjustable fixing, this cover slides over the position of pressing on the beam and can regulate with dog screw;

The lower surface of described fertilizer guiding tube groove sealing device, the lower surface of protective plate, the lower surface of the anti-blocking tubular ditching plow of described grain conductor, the lower edge of described covering device disk are all corresponding with the ground level that the trench digging disk is gone into behind the ground.

The utility model has following actively useful effect

1, sows evenly.

2, penetration performance is good, depth unanimity during big seeding quantity.

3, adopt that the DLC structure makes kind, nutriment in a fertilizer is opened and broadcasted sowing, avoided the rotten of seed to rot, guaranteed the survival rate of seed.

4, replace the roller covering device with the disk covering device, and this disk covering device can do the adjustment of three-dimensional, dependable performance, blinding is tight.

5, the grain conductor lower end is provided with anti-blocking tubular ditching plow, can flat bottom of trench.

6, can be applicable to the sowing of sand and clay soil.

But 7 multiple-units also connect the associating use, are used for the tractor-drawn operation.

Now in conjunction with the accompanying drawings with preferred embodiment:
