[0023] The following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] As Figures 1-4 shown, the intelligent seeder provided by the present utility model has a crawler traveling chassis 1, a sowing operation component 2, and a navigation control component 3. For the crawler traveling chassis 1, a group of traveling motors 11 drive the left and right crawler traveling wheels 12 to move respectively. The left and right crawler traveling wheels 12 are fixedly connected through the chassis frame 13. The traveling motors 11 are respectively located in the slots of the chassis frame 13. The whole machine battery 14 is in the middle of the traveling motors 11. On one side directly above the traveling motor is the whole machine control box, and on the other side is the navigation control box, which are covered by the machine hood.

[0025] The front and rear ends of the seeding installation frame 21 are axially connected with a number of press wheels 22. A seeding motor 24 is fixedly connected to the front end of the rear press wheel 22. One side is axially connected with a coding wheel on the encoder through a mounting bracket. The coding wheel 25 is in contact with any one of the press wheels 22. When the press wheel 22 rotates, it drives the coding wheel 25 to rotate. The rotation speed of the press wheel 22 is determined by the encoder and fed back to the whole machine control box to control the rotation speed of the seeding motor 24. A number of seeders 23 are axially connected to the middle of the installation frame 21 through three shafts. The seeder 23 includes a U-shaped mounting plate 231. The middle of the U-shaped mounting plate 231 is axially connected with a seeding groove wheel in the seed box 232 through an A gear 233. The A gear 233 and a B gear 234 outside the U-shaped mounting plate 231 form a pair of gear pairs. A boat-shaped bracket 235 is provided on the lower side of the U-shaped mounting plate 231. A soil scraping plate 236 is fixedly connected to the front end of the boat-shaped bracket 235. A number of seeders 23 are connected to the seeding installation frame 21 through the front and rear shaft holes of the U-shaped mounting plate 231 and the keyway holes of the B gear 233 and the three shafts. During operation, the row spacing can be adjusted by adjusting the number and distance of the seeders. An A sprocket 26 is fixedly connected to the middle of the same shaft as the B gear 234. The shaft of the seeding motor 24 is connected with a B sprocket 27, and a chain drive is formed through a chain. The seeding motor 24 drives the seeding groove wheel to rotate through the chain drive. A circle of tapered round holes is provided on the circumference of the seeding groove wheel. Seeds enter the tapered round holes of the seeding groove wheel and fall to the ground after the circumferential movement of the seeding groove wheel, realizing seeding. The tapered round holes on the seeding groove wheel have various specifications, and seeding of various granular seeds is realized by replacing the seeding groove wheel. The soil scraping plate 236 located on the seeder 23 scrapes the soil for covering after seeding, and the rear press wheel compresses the soil.

[0026] On the left and right of the front of the seeding installation frame 21, there are A connecting arms 28. The A connecting arms 28 are connected to the fixed rods 16 on both sides of the upper part of the chassis frame 13. On the left and right of the rear of the seeding installation frame 21, there are B connecting arms 29. The middle of the B connecting arms 29 is axially movably connected to the fixed rod 16 on the chassis frame 13, and the upper end is fixedly connected to the electric push rod 15. The other end of the electric push rod 15 is fixed to the fixed rod 16 on the chassis frame. The A connecting arm 28, the A connecting arm 28, the fixed rod 16 and the electric push rod 15 form a four-bar linkage mechanism. The height adjustment of the seeding operation component 2 relative to the crawler walking chassis 1 is realized by the lifting of the electric push rod 15.

[0027] The whole machine is provided with a navigation control component 3. The navigation control component 3 includes a navigation receiver 31 fixed at the front end of the whole machine, a navigation touch screen 32 in the middle of the rear end, and a navigation control box located in the groove of the chassis frame 13. By setting parameters on the navigation touch screen, the whole machine can perform automatic driving operations.

[0028] The whole machine has two operating modes. One is manual operation. Parameters are set through the control panel combined with the navigation touch screen 32 to start the whole machine. If the machine is running in the furrow, adjust the seeding operating mechanism with the electric push rod until it is appropriate (the pressing wheel touches the ground), put the seeds into the seeder, and carry out seeding operations. During operation, the seeding groove wheel in the seeder 23 can be adjusted according to the diameter of the seeds to be sown.

[0029] The other is automatic navigation operation. When the machine moves to the operation field, first connect the navigation signal; then set points A and B on the navigation touch screen. Move the whole machine to the starting point of field operation first and set point A, then move the whole machine to one end of the operation field and set point B. Set the transfer row spacing on the navigation touch screen and click start on the navigation touch screen, and the whole machine starts to operate. During the operation process, the staff can stop the machine operation at any time through the navigation touch screen or the control panel.
