[0015] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0017] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0018] Combine Figure 1-3 As shown, the agricultural seeder includes a frame 1, and a pair of front and rear running wheels are rotatably provided on both sides of the frame 1. Figure 1 The front running wheel is marked as 2.1 and the rear running wheel is marked as 2.2. A pair of liftable furrow openers 3 are provided on the rear side of the vehicle frame 1. The vehicle frame 1 is provided with a carrier plate 4, on which a pair of seeding boxes 5 are provided. A circular opening 6 is provided on the carrier plate 4 in the seeding boxes 5. A seeder is provided in the seeding boxes 5. The seeder includes a seeding tray 7 rotatably mounted on the carrier plate 4. An umbrella-shaped drop-out seat 8 is provided above the seeding tray 7 and a rotating frame 9 is provided below the seeding tray 7. A C-shaped seat 10 is provided between the inner wall of the seeding box 5 and the drop-out seat 8. A sowing interval is formed between the bottom of the C-shaped seat 10 and the seeding tray 7. A circle of sowing holes 11 is provided on the seeding tray 7 between the drop-out seat 8 and the seeding box 7. A drop-out port is provided on the carrier plate 4 in the sowing interval. The drop-out port is connected to a seed guide tube 12. The bottom of the seed guide tube 12 is inserted into the furrow opener 3 on the same side. The vehicle frame 1 is also provided with a rotating mechanism for driving the rotating frame 9 to rotate.

[0019] With the development of agricultural mechanization, traditional manual sowing methods can no longer meet the needs of modern agriculture for efficiency, precision, and labor saving. As a small, lightweight, and flexible agricultural machinery, the seeder has been widely used in agricultural production due to its advantages such as simple operation, high efficiency, and low cost.

[0020] When using this agricultural seeder for sowing, first pour the seeds into the two sowing boxes. The staff must first adjust the two furrow openers downward to contact the ground, and then move the frame forward. During the forward movement of the frame, the furrow opener digs a sowing furrow. At the same time, the seeder discharges the seeds in the sowing box to the discharge port in a quantitative manner. The seeds pass through the seed guide tube and the furrow opener in turn and are finally sown in the sowing furrow, thereby achieving the purpose of sowing.

[0021] In this structure, a stopper 13 is formed at one end of the C-shaped seat 10, and the stopper 13 contacts the seeding plate 7. The seeding plate is provided with an umbrella-shaped drop-out seat, which contacts the C-shaped seat. The C-shaped seat divides the seeding plate into a seeding area and a feeding area, wherein the area between the bottom of the C-shaped seat 10 and the seeding plate 7 is the seeding area. Figure 2-3The rotating mechanism drives the rotating frame to rotate in the opposite direction, and the seeding tray rotates synchronously during this process. When the seeding holes on the seeding tray rotate to the feeding area, the seeds in the seeding box fill the seeding holes in this area. They first pass through the block and then enter the seeding area. When the seeding holes on the seeding tray rotate above the drop opening, the seeds inside fall into the seed guide tube and then through the furrow opener into the seeding furrow.

[0022] In the above process, when the seeding disc rotates in the reverse direction, the block will smooth the seeds in the corresponding seeding hole when it passes through the block, so that the number of seeds in all seeding holes after passing the block is roughly the same. Under the action of the block, the overall seeding quality can be effectively improved.

[0023] In addition, during the entire sowing process, the dropper rotates along with the sowing tray, which can prevent the seeds from piling up in the sowing box and allow the seeds in the sowing box to move toward the feeding area.

[0024] As a preferred structure, Figure 2 , the bottom of the rotating frame 9 passes through a circular opening 6 and is provided with a driven bevel gear 14, and a rotating sprocket 15 is provided on the shaft of the same pair of walking wheels, and a chain 16 is sleeved between the rotating sprockets 15, and a driven gear 17 is provided on the shaft of the front walking wheel 2.1, and a driving pulley 18 is provided on the shaft of the rear walking wheel 2.2. The rotating mechanism includes a driving bevel gear 19 rotatably mounted on the frame 1 and meshing with the driven bevel gear 14, a driven pulley 20 is provided on the shaft of the driving bevel gear 19, and a belt 21 is sleeved between the driven pulley 20 and the driving pulley 18, and the frame 1 is also provided with a driving mechanism for driving the driven gear 17 to rotate.

[0025] During the sowing process, a rotating mechanism is used to drive the seeder to rotate to complete the sowing. First, the driving mechanism is used to drive the driven gear to rotate, and the front travel wheel moves forward. Under the linkage of the chain, all the travel wheels move forward. During this process, the active pulley rotates, and the driven pulley rotates under the action of the belt, and the active bevel gear rotates synchronously. At the same time, the driven bevel gear meshed with the active bevel gear rotates, that is, the rotating frame starts to rotate, and the sowing disc rotates accordingly. First, the sowing holes in the feeding area on the sowing disc are filled with seeds. During the rotation of the sowing disc, the sowing holes filled with seeds first pass through the block, and then enter the sowing area until they rotate to the drop port. The seeds inside fall into the seed guide tube and pass through the furrow opener to fall into the sowing furrow.

[0026] In this structure, the driving mechanism includes a rotating shaft 36 rotatably mounted on the frame 1, and a driving gear 23 and a rotating gear 24 are provided on the rotating shaft 36. The driving gear 23 is meshed with the driven gear 17. A driving motor 25 is provided on the frame 1, and a driving gear 26 is provided on the driving shaft of the driving motor 25. The driving gear 26 is meshed with the rotating gear 24.

[0027] In this structure, the two front running wheels are independently provided and driven by corresponding drive mechanisms. This allows the planter to turn according to the actual road conditions while traveling by controlling the working mode of the two drive mechanisms, thereby improving the planter's flexibility.

[0028] When the drive mechanism drives the driven gears to rotate, such as when the seeder moves forward, both gears simultaneously drive the corresponding drive gears, causing the rotating gears to rotate synchronously. Driven by the driving gear, the driven gears also rotate together, thereby completing sowing. During sowing, the two front wheels move forward. Therefore, when using this agricultural seeder for sowing, the operator only needs to hold onto the handrails on the frame.

[0029] Further as a preferred structure, Figure 1-2 A lifting plate 27 is slidingly provided on the frame 1, and the trench opener 3 is provided on the lifting plate 27. A pair of connecting rods 28 and a pair of lifting rods 29 are rotatably provided on the frame 1 and the lifting plate 27 respectively. An intermediate rod 30 is rotatably provided on the lifting rod 29. The connecting rod 28 is rotatably connected to the intermediate rod 30. A screw sleeve 31 is rotatably provided on the intermediate rod 30. A screw rod 32 is inserted into the two screw sleeves 31. Two threaded sections in opposite directions are formed on the screw 32, and a shaking handle 33 is also provided on the screw.

[0030] Before sowing, workers need to lower the furrow opener to ensure contact with the ground. Specifically, they simply turn the crank handle, which causes the screw to rotate. As the screw rotates, the two screw sleeves move outward in opposite directions along the length of the screw. As the two screw sleeves move outward, the connecting rod and lifting rod on the same side also rotate outward. During this process, the lifting plate moves downward a short distance, causing the two furrow openers to move downward.

[0031] In this embodiment, a hollow connecting post 34 is located above the furrow opener. A hollow drop post 35 is located on the vehicle frame 1 and directly above the connecting post. The bottom of the drop post 35 is inserted into the top of the connecting post 34. The bottom end of the seed guide tube 12 is a hose, which is inserted into the top of the drop post 35. This ensures that the vertical movement of the furrow opener will not affect the seed guide tube.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
