Turning to the upper flange connecting seat to be fixed on the lower surface of front chassis, lower flange is fixed on the upper surface of rear chassis; During installation, upper flange is enclosed within lower flange, and anti-wear sleeve has been clipped in the middle wear-resisting effect. Turn to connection seat and arc guide rail mechanism to coordinate, make to turn to more steadily round and smooth. Described arc guide rail mechanism is made up of the arc guide groove 21 on rear chassis and the clamping device being fixed on front chassis, described arc guide groove is one section of angle is the arc groove of 45 ��, it is distributed along rear chassis front-rear center line lateral symmetry, arc groove width is 9mm, the center of circle of arc groove with turn to that to be connected seat concentric, the radius of arc groove is clamping device center and turns to the distance being connected between seat center. Clamping device stepped up from above sheet 22, under step up sheet 23, fastener shaft 24 and ball 25 and form, ball divide two groups, front and back be separately mounted to step up sheet and under step up between sheet both sides; Often group ball divides two rows; Upper step up sheet and under step up sheet mills out hemisphere groove, ball diameter is 8mm, and the half of ball is stuck in hemisphere groove, and the chassis at arc groove edge clamped by two rows ball. Fastener shaft passes through in arc guide groove, utilizes arc guide groove to guide clamping device to circle. By arc guide rail mechanism with turn to connection seat to be capable of turning to, and the problem that chassis, two pieces, front and back is trembleed up and down can be solved in middle interconnecting piece position.
Described running gear is mainly made up of parts such as two drive motors, four wheels, bearing block and main shafts. Two front-wheels are fixed on front chassis by bearing block, are driven by two drive motors respectively, and the kind of drive is chain drive. Two trailing wheels are fixed on rear chassis, for driven pulley.
Described seeding apparatus is made up of kind of case 3, seeds discharging box 16, planetary reduction gear motor 18, seed metering guide tube 14, plough 13, land wheel 15 and plough elevating mechanism. Seed-box is supported on the top of front chassis latter half by line slideway 4 and column 19. Seed-box two bottom sides respectively has a square hole, and below square hole, correspondence installs two feed mechanism for seeds respectively, and seed metering guide tube is vertically mounted on the lower section of two feed mechanism for seeds by elevating mechanism. What the seed inlet of seed metering guide tube faced feed mechanism for seed goes out kind of a mouth, and seed out, just falls in seed metering guide tube from feed mechanism for seed. Seed metering guide tube is adjustable up and down under the effect of elevating mechanism, realizes the adjustment of tilling depth on the one hand; On the other hand, during not farming, seed metering guide tube just rises to highest point and conveniently walks. Planetary reduction gear motor 18 is driven by feed shaft and regulates the seed wheel of feed mechanism for seed and rotates, to realize precision drilling.
Described seed metering guide tube 14 is made by the square tube of a 30*40, pipe range 130mm, is vertically installed at the lower section of feed mechanism for seed by elevating mechanism, and it is the angle of 15 degree that seed metering guide tube bottom goes out one end of kind of mouth and ground, angle is towards rear, to prevent soil plug seed metering guide tube from causing broadcast leakage. Plough 13 is welded on seed metering guide tube bottom, and the bottom of plough is concordant with the bottom of seed metering guide tube.
Described plough elevating mechanism includes reducing motor 10, elevator 11, line slideway 4, guide rail slide block 5 and copying spring 6. Elevator, line slideway are vertically fixed on front chassis. Slide block is mobilizable to be arranged in line slideway; Slide block one end is connected with seed metering guide tube 14 by connector so that seed metering guide tube can be followed slide block 5 and be moved up and down. The slide block other end is connected by connector with elevator; Plough is welded on seed metering guide tube end, moves along with the movement of seed metering guide tube. Being driven elevator operating by reducing motor, elevator drives seed metering guide tube and plough to move up and down by some connecting elements, realizes the adjustment of tilling depth with this. The up and down motion of seed metering guide tube is played guiding function by line slideway and the slide block matched with line slideway.
The present invention being connected with electric control gear according to prior art, electric control gear includes control system, converter, photoelectric encoder etc.; Control system can adopt single-chip microcomputer etc.; Electric control gear adopts prior art all can realize; Lifting motor, planetary reduction gear motor, drive motor, converter, photoelectric encoder etc. are connected with controlling system. It is first turned on main power to power to all automatically controlled original papers, controls lifting motor 10 by control system and operate, according to the tilling depth that agronomy specifies, make plough drop to suitable position. By controlling converter, regulate the rotating speed of drive motor 7, control the gait of march of seed-sowing machine with this. After drive motor runs well, being arranged on the photoelectric encoder on main shaft will get up the rotary speed information collection of tire and be returned to control system. According to speed of drilling, control the rotating speed that current driving speed lower planet decelerating step motor should keep, and control the operating of planetary reduction gear motor with this rotating speed. Planetary reduction gear motor drives feed shaft to rotate by Chain conveyer, and then controls the rotation of seed wheel. Seed enters feed mechanism for seed from seed-box, drops in seed metering guide tube by the drive of seed wheel, is led in the soil holding ditch successfully by seed metering guide tube under gravity. Gait of march, tilling depth, the amount of broadcasting etc. can be changed in operation at any time according to practical situation.
Above are only the specific embodiment of the present invention, the various changes made when without departing from the spirit and scope of the present invention and modification, all equivalent technical schemes fall within scope of the invention.
