Description

Technical Field

[0001] This application belongs to the field of seeder technology, specifically a wheat seeder. Background Technology

[0002] Wheat planters, as agricultural machinery specifically designed for sowing wheat, generally consist of a frame, seed box, fertilizer box, seed metering device, fertilizer metering device, furrow opener, soil covering device, and compaction wheel. They are usually connected to a tractor via a three-point suspension. During operation, the tractor drives the seed metering device and fertilizer metering device to sow seeds and fertilizer into the soil at a certain rate, row spacing, and depth, and completes the processes of soil covering and compaction, thereby improving sowing quality and operational efficiency.

[0003] For example, utility model patent CN223142472U discloses a wheat disc seeder, which includes a feeding box and a feeding assembly disposed on the outer side of the end of the feeding box. The feeding assembly includes a feeding wheel, a feeding trough, and a connecting shaft. The feeding wheel on the inner side of the end of the feeding box rotates through rollers, allowing the seed material to smoothly enter the feeding trough. Subsequently, the rotation of the feeding wheel spreads the seed material into the soil. This method simplifies the sowing process, improves sowing efficiency, and saves a lot of time and costs. The design of the feeding wheel ensures that the seed material is evenly distributed in the feeding trough, thereby achieving uniform seed distribution during sowing, which is beneficial to the uniform growth of wheat.

[0004] However, it was discovered during actual use that the device drives the feeding wheel to rotate via a connecting shaft, causing the seed material in the feeding trough to be scattered into the soil. However, there is a structural gap between the feeding wheel and the feeding box of the device, which causes the seed material to enter the feeding box through the rectangular through-slot and be discharged directly. When the seed material is located between the feeding wheel and the feeding box, it will also affect the overall movement. At the same time, the seed material inside the feeding wheel is prone to overflow during rotation, which will affect the normal sowing effect. Therefore, a wheat seeder is provided.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] refer to Figures 1-4As shown, a wheat seeder includes a main support 1. A connecting bracket 19 is hinged to the outer surface of the main support 1 near its center. A pin hole 20 is provided on the top surface of the connecting bracket 19 away from the main support 1. Bearing seats 2 are fixedly installed at the left and right ends of the main support 1, and a rotating shaft 3 is fixedly installed through the middle of the bearing seats 2. Moving wheels 15 are fixedly installed at the left and right ends of the rotating shaft 3, and multiple triangular plates 16 are installed in a circumferential array on the outer surface of the moving wheels 15. The main support 1 provides stable support for the overall structure. The connecting bracket 19 and the pin hole 20 allow personnel to insert pins into the pin hole 20, facilitating connection with power equipment such as tractors and ensuring stable movement of the equipment. The bearing seats 2 ensure flexible rotation of the rotating shaft 3 and reduce friction loss. The moving wheels 15, in conjunction with the triangular plates 16, enhance the equipment's grip in the field, preventing slippage, and maintaining stable movement, especially in soft or muddy soil, ensuring uniform sowing.

[0017] refer to Figures 1-4 As shown, two circular shells 4 are fixedly installed on the outer surface of the main support 1. A rotating plate 5 is fixedly installed inside the circular shell 4 on the outer surface of the rotating shaft 3. A feeding pipe 6 is fixedly installed on the outer surface of the circular shell 4 near the top. A hopper 21 is fixedly installed at the top of the feeding pipe 6. A transparent glass is fixedly installed on the side of the hopper 21. The rotating shaft 3 can drive the rotating plate 5 to rotate synchronously, which can push the seeds in the shell evenly. The hopper 21 can increase the seed storage capacity and reduce the frequency of feeding. The transparent glass makes it easy to observe the remaining seed level, which is convenient for timely replenishment and avoids missed sowing due to seed shortage, thus improving the continuity of operation.

[0018] refer to Figures 1-4 As shown, a conveying shell 7 is fixedly installed on the inner wall of the circular shell 4. One end of the conveying shell 7 extends into the interior of the feed pipe 6. An arc-shaped discharge pipe 8 connected to the conveying shell 7 is fixedly installed on the outer surface of the circular shell 4. A discharge hole is opened on the outer surface of the arc-shaped discharge pipe 8 away from the circular shell 4. A furrowing head 22 is fixedly installed on the end of the arc-shaped discharge pipe 8 away from the circular shell 4. The conveying shell 7 facilitates the connection between the feed pipe 6 and the arc-shaped discharge pipe 8 to form a seed conveying channel, ensuring the directional flow of seeds. The arc-shaped design of the arc-shaped discharge pipe 8 reduces the resistance of seed falling and avoids blockage. The furrowing head 22 allows furrows to be opened in the soil before sowing, so that the seeds fall directly into the furrows, ensuring consistent sowing depth, improving seed germination rate, and reducing seed loss due to exposure on the ground.

[0019] refer to Figures 1-4As shown, a baffle 9 is provided inside one end of the conveying housing 7. A connecting rod 10 is fixedly installed on the bottom surface of the baffle 9. The bottom end of the connecting rod 10 extends into the interior of the circular housing 4. A U-shaped frame 11 is fixedly installed at the bottom end of the connecting rod 10. A roller 12 is rotatably connected inside the U-shaped frame 11. A spring 13 is provided on the outer surface of the connecting rod 10 above the U-shaped frame 11. The top end of the spring 13 is fixed to the inner wall of the conveying housing 7. Multiple arc-shaped protrusions 14 are fixedly installed on the outer surface of the rotating plate 5. When the rotating plate 5 rotates, the arc-shaped protrusions 14 intermittently push up the roller 12, which drives the baffle 9 to move upward through the connecting rod 10, opening the channel of the conveying housing 7 so that the seeds can pass through smoothly. When the arc-shaped protrusions 14 leave the roller 12, the spring 13 returns to its original position, driving the baffle 9 to move downward and close the channel, realizing intermittent seeding, accurately controlling the seeding amount and row spacing, avoiding seed waste. The elasticity of the spring 13 ensures that the baffle 9 returns to its original position reliably, ensuring a stable seeding rhythm and improving seeding uniformity.

[0020] refer to Figures 1-4 As shown, an L-shaped bracket 17 is fixedly installed on one side of the feed pipe 6, and soil covering plates 18 are fixedly installed on the left and right sides of the L-shaped bracket 17 respectively. The L-shaped bracket 17 can stably support the soil covering plates 18. The soil covering plates 18 can push the soil after sowing back into the furrow to cover the seeds, which can retain moisture and heat, which is conducive to seed germination. At the same time, it can prevent birds from pecking at the seeds and improve the seed survival rate. The arc-shaped discharge pipe 8 is divided into two sections, and the two sections of the arc-shaped discharge pipe 8 are connected by a flexible hose, such as a stainless steel flexible hose. An adjustment mechanism connected to the arc-shaped discharge pipe 8 is installed on one side of the L-shaped bracket 17. The adjustment mechanism can drive the arc-shaped discharge pipe 8 to adjust, so that the arc-shaped discharge pipe 8 can contact the soil for furrow sowing during sowing and can be reset when not sowing, thus facilitating the overall movement.

[0021] The implementation principle of a wheat seeder embodiment of this application is as follows: When the wheat seeder is working, the operator can first connect to the power equipment through the connecting bracket 19. The power will drive the rotating shaft 3 to rotate. At this time, the set movable wheels 15 can drive the seeder forward. The triangular plates 16 on the movable wheels enhance the grip to ensure stable movement. When the seeder moves, the furrow opening head 22 can open furrows, and the seeds enter the interior of the feed pipe 6 from the hopper 21. When the rotating shaft 3 rotates, it can synchronously drive the rotating plate 5 to rotate. The arc-shaped protrusions 14 on the rotating plate 5 intermittently push up the rollers 12, which are connected to the rotating shaft 3. Rod 10 moves baffle 9 upward to open the channel of conveying housing 7. Seeds enter the arc-shaped discharge pipe 8 through the conveying housing 7 and fall into the soil through the discharge hole, realizing the wheat sowing operation. When the arc-shaped protrusion 14 rotates past the roller 12, the spring 13 resets and drives baffle 9 to close the channel, completing one intermittent sowing, realizing precise control of sowing amount and row spacing, effectively avoiding the problem of seed overflow or uneven discharge. At the same time, the soil covering plate 18 on the L-shaped bracket 17 covers the seeds with soil as the equipment moves forward. In this way, the integrated operation of furrowing, sowing and soil covering can be realized, and the wheat sowing process can be completed efficiently and evenly.
