[0021] The self-propelled wheeled chassis includes four traveling wheels 2 and a driving motor; each traveling wheel 2 is matched with an independently controlled driving motor. The self-propelled wheeled chassis is fixedly mounted on both sides of the device frame 1. The self-propelled wheeled chassis is used to drive the planting vehicle forward, backward, and turn, so as to ensure that the torque on the wheel is sufficient to have sufficient operating power in the soil. The overall chassis is a four-wheel drive device. The left and right longitudinally arranged tires of the self-propelled wheeled chassis can achieve a U-turn on the spot by outputting power of the same speed but different directions, and can achieve differential turning by outputting power of different speeds but the same direction.

[0022] The device frame 1 is arranged on a self-propelled wheeled chassis; the device frame 1 is formed by splicing fixed riveted blocks and aluminum profiles, and the fixed riveted blocks are connected in pairs to ensure the stability and firmness of the device frame 1.

[0023] The rotary tillage breaking unit is arranged at the upper center of the device frame 1, and includes a bottom mounting base A5, a driving motor 3, a transmission gear unit, a screw rod 6, a slide block 7, a drill motor 8 and an auger rod 9;

[0024] Among them, the active motor 3 is installed on the device frame 1 through the mounting seat A5, and the active motor 3 is provided with a driving gear 4; the transmission gear unit includes a short shaft, and a driven gear A11 and a driven gear B12 fixed on the short shaft and the lower end; the screw 6 is installed on the device frame 1 through the mounting seat B10, and a slider 7 with an internal thread is provided on the screw 6, and a driven gear C13 is fixed on the upper end of the screw 6; the slider 7 is fixed with a drill motor 8, and the output shaft of the drill motor 8 is fixed with Auger rod 9; when the active motor 3 drives the active gear 4 to rotate, the active gear 4 drives the driven gear B12 to rotate, the driven gear B12 drives the driven gear A11 on the short shaft to rotate, and the driven gear A11 drives the upper driven gear C13 coaxial with the screw 6 to rotate, thereby driving the screw 6 to rotate and drive the drill motor 8 on the slider 7 to rise or fall; when the auger rod 9 on the output shaft of the drill motor 8 descends and is inserted into a certain depth underground, the drill motor 8 controls the auger rod 9 to rotate and break the ground.

[0025] The sowing unit is arranged behind the rotary tillage and soil breaking unit on the frame, and includes a seed bin 14, a conveyor belt 15 and a seed drop guide slide 16. The bottom end position of the seed drop guide slide 16 is adapted to the position of the auger rod 9, so that the seeds fall into the grooves drilled by the auger rod 9 in front.

[0026] The seed conveyor belt 15 and the seed bin 14 are designed as an integrated mechanism, including a motor, a gear shaft, a chain, a conveyor belt 15, a seed bin 14, and a seed guide slide 16. The motor is installed on the device frame 1, and the seed bin 14 is penetrated by the conveyor belt 15 in front and back, and the left and right sides are formed into a slope around the conveyor belt 15, which is convenient for the seeds to slide onto the conveyor belt 15. The seed guide slide 16 is fixed on the device frame 1, and the installation width is smaller than the width of the conveyor belt 15, and baffles 17 are provided on both sides of the guide slide 16 to ensure that some high-speed moving seeds are restrained to prevent flying seeds. The length of the slide body extends to the gully completed by the rotary tillage breaking unit and the furrowing mechanism, which is convenient for guiding the seeds directly into the soft soil.

[0027] The soil covering and seed pressing unit is arranged at the rear of the sowing unit, and includes a soil pressing wheel 18 and a group of soil covering plates 19. The soil pressing wheel 18 is fixed on a connecting shaft, and connecting seats are arranged at both ends of the connecting shaft. A spring 21 is fixed on the upper end of the connecting seat, and the other end of the spring 21 is fixed on the frame; the soil pressing wheel 18 will be connected to the gear mechanism through an optical shaft. This structure is a driven device and does not include an active part, and the spring 21 makes the soil pressing wheel 18 fit the ground in real time.

[0028] The soil covering plates 19 are located at both sides of the rear of the soil pressing wheel 18, and the two soil covering plates 19 are arranged in a V-shape with an inward inclination, so as to cover the soil drilled out by the rotary tillage breaking unit toward the middle.

[0029] As an improvement of the scheme, an auxiliary furrow opener 20 is also included, which is arranged on the slider 7 and is located behind the auger rod 9; the auxiliary furrow opener 20 is an inverted trapezoidal shovel-shaped setting. The furrow opener 20 will rise and fall with the drill bit to widen the furrow drilled by the auger rod 9, so that the seeds can fall into the furrow accurately.

[0030] As an improvement to the solution, a connecting belt 22 is provided between the mounting seat A5 and the mounting seat B10 to enhance the stability of the two as a whole.

[0031] The utility model controls the operation of each motor through a controller.

[0032] Scatter the bean seeds to be planted in the sowing unit, press the travel switch that controls the precision seeder, and the Robot Pro controller will initialize the motor of the entire precision seeder and give the four independent motors of the self-propelled wheeled chassis an initial speed. The speed can be manually adjusted according to the speed of the conveyor belt 15 in the sowing unit. The four-wheel drive speed of the precision seeder can achieve the sowing spacing of different beans and crops in different terrains. On the Robot Pro software of the controller, the speed of the drill motor 8 is set to 8, and the speed of the active motor 3 is set to 8. At the beginning, the motor rotates forward, and together with the rotary tillage breaking unit and the auxiliary ditching mechanism, it moves downward until the auger rod 9 and the auxiliary ditching mechanism touch the ground and penetrate 3-5 cm into the ground. At this time, the speed of the four independent motors of the self-propelled wheeled chassis is set to 6. When the precision seeder starts to move as a whole, the Robot Pro controller will set the speed of the independent motor controlling the transmission belt in the sowing unit to 3. At this time, the seeds to be sown will be transported by the conveyor belt 15 through the seed drop guide slide 16, and slide into the soft soil and gullies treated by the auger rod 9 and the auxiliary ditching mechanism, waiting for the soil pressing wheel 18 of the soil covering and seed pressing unit to press the seeds into the soil, and the soil covering plate 19 will push the soil around the seeds into the gully where the seeds are located to bury them. After the whole work is completed, Robot Pro will first set the speed of the four independent motors of the independent motor controlling the seed conveyor belt 15 and the seed bin 14 and the self-propelled wheeled chassis to 0. After stopping the seeding and advancing links, the controller will simultaneously give the drill motor 8 and the active motor 3 reverse electrical signals to facilitate the spiral drill rod 9 to be rotated out of the deep soil, and the rotary tillage and soil breaking unit will rise to the preset position, and the drill motor 8 and the active motor 3 will be set to stop electrical signals at the same time.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
