Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to an automated agricultural machinery seeder. Background Technology

[0002] China, a vast country and a major agricultural nation, has long been committed to developing agricultural machinery and improving its mechanization level. In plains areas, large-scale automated planting machinery has been widely adopted, significantly improving agricultural efficiency. However, in some mountainous and hilly areas, due to inconvenient roads, uneven terrain, and small-scale planting, large-scale automated planting machinery is difficult to operate, and these areas still mainly rely on semi-automated or manual sowing. A title and abstract search of the China Patent Database using the search term "automatic agricultural sowing" yielded several relevant patents.

[0003] For example, patent CN221768705U proposes an agricultural automatic feeding seeding device, including a battery frame. A suspension assembly is provided on the top right side of the battery frame. The suspension assembly includes a vertical plate. A movable plate is embedded in the side of the vertical plate through a through groove. Two clamping plates are symmetrically embedded in the movable plate through guide grooves. A feeding assembly is suspended inside the two clamping plates. The feeding assembly includes a hopper. A loosening assembly is suspended and installed inside the hopper. The loosening assembly includes a suspension plate that is connected and fixed to the vertical plate. A drive motor is installed at the top of the suspension plate. The output end of the drive motor passes through the suspension plate and is connected to a main gear. A secondary gear is meshed with the left side of the main gear through teeth. The secondary gear is fixed on the surface of the connecting shaft. A loosening vane is connected to the outer side of the bottom end of the connecting shaft. The top end of the connecting shaft is rotatably connected to the suspension plate.

[0004] For example, patent CN221653151U proposes an automatic corn planting device for agricultural use, including a planting box. A feeding frame is fixedly connected to the bottom of the planting box. The feeding frame has a through-hole that is connected to the planting box. A stirring rod is rotatably connected inside the planting box and passes through the planting box. Multiple stirring blades are fixedly connected to the outer wall of the stirring rod. A rotating rod is rotatably connected inside the feeding frame and passes through the feeding frame. A conveying cylinder is fixedly connected to the outer wall of the rotating rod. Multiple planting grooves are opened on the outer wall of the conveying cylinder. Multiple blocking blocks are provided around the periphery of the conveying cylinder and are fixedly connected to the feeding port. A first transmission block is fixedly connected to both ends of the stirring rod. A second transmission block is fixedly connected to both ends of the rotating rod. A track is driven through the outer wall between the first and second transmission blocks.

[0005] Both of the aforementioned automatic seeding devices are suitable for mountainous and hilly areas where large-scale automated planting machinery cannot easily access the fields. They can automatically dispose of seeds, thus improving agricultural planting efficiency in these areas to some extent. However, agricultural planting involves more than just seed placement; it also requires digging furrows in the land and covering the seeds with soil. In these areas, furrow digging before sowing is typically done manually using hoes or hand-pulled plows, and covering the seeds with soil after placement is also done manually. The existing patented technologies mentioned above cannot achieve the entire process of furrow digging, seed placement, and soil covering in one step. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model proposes an automated agricultural machinery seeder to solve the problem mentioned in the background art that existing automatic seeding devices cannot achieve land furrowing, seed placement, and soil covering in one step in some mountainous and hilly areas where large-scale automated planting machinery is difficult to operate.

[0007] This utility model is achieved through the following technical solution: An automated agricultural seeder includes a frame, an automatic feeding mechanism, and a plowhead mounted on the frame. The plowhead is located at the bottom of the frame, and first baffles are provided on both the front and rear sides of the plowhead. The tops of the first baffles are fixed to the frame, and a channel for guiding soil is formed between the plowhead and the two first baffles. The automatic feeding mechanism is used to automatically feed seeds into the furrows opened by the plowhead. When the plowhead opens the furrows, the two first baffles can collect the soil turned over by the plowhead. The automatic feeding mechanism follows the plowhead to feed the seeds into the furrows. Soil is turned over from the top of the plowhead and falls into the furrows opened by the plowhead to cover the seeds in the furrows.

[0008] Furthermore, the seeder also includes two casters mounted on the frame at intervals, which are used to help stabilize the frame to prevent it from tipping over and to help the frame move on the ground so that the plow head can open furrows in a predetermined direction.

[0009] Furthermore, the seeder also includes a handle for manual traction. One end of the handle is fixedly mounted on the frame. Farmers pull the handle to move the whole machine. Farmers walk in front, and the plow opens furrows behind them. An automatic feeding mechanism puts seeds into the newly opened furrows, and the soil falls into the furrows after passing over the top of the plow to form a covering soil.

[0010] Furthermore, the automatic feeding mechanism mainly consists of a hopper, a feeding wheel, a feeding pipe, a second baffle, a motor, and a battery. The hopper is fixedly installed on the top of the frame, with a funnel-shaped bottom and a feeding port. The feeding wheel is rotatably mounted on the frame and located below the hopper. A motor for driving the feeding wheel is installed on the frame. The outer wall of the feeding wheel has multiple grooves for accommodating seeds. When one of the grooves rotates to below the feeding port, the seeds in the hopper fall into the groove. The feeding pipe is installed on the frame, with its top extending below the feeding wheel to collect the seeds falling from the grooves, and its bottom extending to the back of the plow. The feeding pipe throws the seeds into the groove. A second baffle is provided on one side of the feeding wheel to prevent the seeds in the grooves from falling out during the transfer between the feeding port and the top of the feeding pipe. The battery is installed on the frame to power the motor.

[0011] Furthermore, the back side of the plow is inclined, and the bottom of the feed pipe extends in a curved shape to below the inclined back side of the plow. After the plow makes a trench, before the soil turns over the top of the plow and falls into the trench, the feed pipe puts the seeds into the trench to ensure the success rate of seed covering.

[0012] Furthermore, a feeding hopper is fixedly installed at the top of the feeding pipe. The feeding hopper is funnel-shaped and is used to receive and transfer seeds between the feeding wheel and the feeding pipe, ensuring that the seeds can smoothly enter the feeding pipe.

[0013] Furthermore, a second crossbeam plate is provided between the two casters. The second crossbeam plate has a U-shaped structure, with its two ends welded to the top of the wheel frames of the two casters respectively. Two screw rods spaced apart front to back are welded to the top surface of the second crossbeam plate. A third crossbeam plate is welded to the frame, and two sleeves spaced apart front to back are welded to the third crossbeam plate. The two sleeves are respectively fitted onto the two screw rods, and the upper and lower ends of the sleeves on each screw rod are threaded with nuts. The two nuts can fix the screw rods on the sleeves to prevent the screw rods from moving up and down, thereby fixing the installation position of the second crossbeam plate on the frame. The above structure makes the installation height of the two casters on the frame adjustable. By turning the nuts to adjust the installation height of the second crossbeam plate on the frame, the height of the two casters can be adjusted simultaneously.

[0014] Furthermore, the handle is an adjustable telescopic rod structure consisting of an outer tube and an inner rod, which can adapt the length of the handle to the height of the farmer, making it more labor-saving.

[0015] Furthermore, the top of the hopper is equipped with a flip-open and closable cover. When the cover is closed, it can prevent the seeds in the hopper from falling out, especially when the hopper is tilted, it can prevent the seeds from being poured out.

[0016] As can be seen from the above technical solution, the automated agricultural machinery seeder provided by this utility model has the following beneficial effects: This seeder can be used for sowing operations in mountainous and hilly areas where large automated planting machinery cannot access the site. It can use a plow to open furrows and an automatic feeding mechanism to automatically place seeds in the furrows. When the plow opens the furrows, two first baffles can collect the soil turned over by the plow. The automatic feeding mechanism follows the plow and puts the seeds into the furrows. The soil is turned over from the top of the plow and falls into the furrows opened by the plow to cover the seeds in the furrows. The land opening, seeding and soil covering are completed in one step, realizing automated sowing operations. Compared with the traditional operation method in the above-mentioned areas, which involves manually opening furrows, manually placing seeds and finally workers covering the soil, this seeder completes land opening, seeding and soil covering in one step, which can improve sowing efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0024] An automated agricultural machinery seeder, such as Figures 1 to 3 As shown, it mainly consists of a frame 1, an automatic feeding mechanism 2, casters 3, a plow head 4, a first baffle 5, a handle 6, a first crossbeam plate 7, a second crossbeam plate 8, a third crossbeam plate 9, a sleeve 10, and a screw 11.

[0025] The frame 1, as Figures 1 to 3 As shown, it is a U-shaped frame structure made of stainless steel, with the left and right sides connected. It serves as the mounting base for the automatic feeding mechanism 2, casters 3 and plow 4.

[0026] The plowshare 4 is made of alloy steel or ferromanganese and is a conventional agricultural implement, such as... Figures 1 to 3 As shown, the plow head 4 has first baffles 5 welded to both the front and rear sides. The tops of the two first baffles 5 are welded or bolted to the bottom of the frame 1. The cutting edge of the plow head 4 is set to the left, and its back side is inclined. The back side of the plow head 4 refers to the side opposite to its forward direction. When the plow head 4 moves forward, it opens a groove on its back side. A channel for guiding soil is formed between the plow head 4 and the two first baffles 5.

[0027] The caster 3, such as Figures 1 to 3 As shown, it has two casters 3, which are installed on the frame 1 and are distributed at intervals in front and behind, and are located on the right side of the frame 1, that is, the back side of the plow head 4 or the rear side of the plow head 4 in the forward direction. The two casters 3 are used to help stabilize the frame 1 to avoid tipping over, and to help the frame 1 move on the ground so that the plow head 4 can open furrows in a predetermined direction. Specifically, the casters are rubber wheels commonly used on existing micro tillers.

[0028] The handle 6, as Figure 1 As shown, one end of the machine is fixedly installed on the frame 1, and the other end is welded with a handle perpendicular to it. The handle and the inner rod 6.2 form a T-shaped structure, which makes it easy for farmers to hold the handle and drag the handle 6. Farmers drag the handle 6 to move the whole machine. Farmers walk in front, and the plow 4 opens furrows behind them. The automatic feeding mechanism 2 puts seeds into the newly opened furrows. The soil falls into the furrows after passing over the top of the plow 4 to form a covering soil.

[0029] The automatic feeding mechanism 2, such as Figures 1 to 3As shown, it is installed on the frame 1 and is used to automatically feed seeds into the furrows opened by the plow head 4; specifically, the automatic feeding mechanism 2 mainly consists of a hopper 2.1, a feeding wheel 2.2, a feeding hopper 2.3, a feeding pipe 2.4, a second baffle 2.5, a cover plate 2.6, a motor 2.7, a battery 2.8, and a rotating shaft 2.9; The hopper 2.1 is fixedly installed on the top of the frame 1. Specifically, the top plate of the frame 1 has a through hole for the lower part of the hopper 2.1 to pass through. The outer side wall of the hopper 2.1 is welded with a flange, which is bolted to the top plate of the frame 1 for easy disassembly and assembly. The bottom of the hopper 2.1 is funnel-shaped and has a discharge port. The feeding wheel 2.2 is rotatably mounted on the frame 1 and located below the hopper 2.1. The frame 1 is equipped with a motor 2.7 for driving the feeding wheel 2.2 to rotate. Specifically, a rotating shaft 2.9 is provided between the front and rear side walls of the frame 1. The feeding wheel 2.2 is fixed on the rotating shaft 2.9. One end of the rotating shaft 2.9 is connected to the power output end of the motor 2.7, and the other end is rotatably connected to the side wall of the frame 1 through a bearing. The motor 2.7 is a stepper motor or servo motor with a reducer. It is a conventional product with various mature product models. It can be conventionally selected and installed according to its product manual. The seeder also includes a switch for controlling the start and stop of the motor 2.7, which is installed on the handle at the end of the handle 6, making it convenient for farmers to operate the start and stop of the motor 2.7. The outer wall of the feeding wheel 2.2 is provided with multiple grooves 2.2.1 for accommodating seeds. When the feeding wheel 2.2 rotates, each groove 2.2.1 on its outer wall rotates to the bottom discharge port of the hopper 2.1. When one of the grooves 2.2.1 rotates to the discharge port, it connects with the discharge port, and the seeds in the hopper 2.1 fall into the groove 2.2.1. After the groove 2.2.1 containing the seeds continues to rotate, the outer wall of the feeding wheel 2.2 seals the discharge port at the bottom of the hopper 2.1 to prevent the seeds from leaking out, until the next groove 2.2.1 rotates to the discharge port and connects with it. The feeding pipe 2.4 is installed on the frame 1. Specifically, the bottom plate of the frame 1 has a through hole through which the feeding pipe 2.4 can pass. The top of the feeding pipe 2.4 is welded with a feeding hopper 2.3. The feeding hopper 2.3 is funnel-shaped, and its top opening size is larger than the size of the groove 2.2.1, ensuring that when the groove 2.2.1 passes over the feeding hopper 2.3, the seeds inside can fall smoothly into the feeding hopper 2.3, and then fall from the feeding hopper 2.3 into the feeding pipe 2.4. The bottom of the feeding pipe 2.4 extends in a curved shape to the underside of the inclined back side of the plow head 4. After the plow head 4 makes a trench, before the soil turns over the top of the plow head 4 and falls into the trench, the feeding pipe 2.4 puts the seeds into the trench, ensuring the success rate of seed covering with soil. The second baffle 2.5 has an arc-shaped plate structure and is located on the right side of the feeding wheel 2.2. Its front and rear ends are welded to the front and rear side walls of the frame 1, respectively. It is coaxial with the feeding wheel 2.2. The outer side wall of the feeding wheel 2.2 is in close contact with the inner side wall of the second baffle 2.5. The feeding wheel 2.2 rotates clockwise under the drive of the motor 2.7. After the seeds are filled into the groove 2.2.1, it rotates along the inner side of the second baffle 2.5. The second baffle 2.5 can block the seeds and prevent them from falling out until the groove 2.2.1 containing the seeds rotates into the receiving range of the feeding hopper 2.3. The battery 2.8 is installed at the bottom of the frame 1 and is used to power the motor 2.7. It is a rechargeable battery 2.8, which is a conventional product and the model can be selected conventionally. The top of the hopper 2.1 is equipped with a flip-open and closable cover plate 2.6. Closing the cover plate 2.6 can prevent the seeds in the hopper 2.1 from falling out, especially when the hopper 2.1 is tilted, it can prevent the seeds from being poured out. Specifically, one end of the cover plate 2.6 is hinged to one side of the top of the hopper 2.1, and the other end is detachably connected to the other side of the top of the hopper 2.1 by a spring latch. The spring latch is a known product with an elastic locking function, which can prevent the cover plate 2.6 from opening automatically.

[0030] To adjust the furrowing depth of the plowshare 4, the mounting height of the two casters 3 on the frame 1 is adjustable; specifically, as shown... Figures 1 to 3 As shown, a second crossbeam plate 8 is provided between the two casters 3. The second crossbeam plate 8 has a U-shaped structure, and its two ends are respectively welded to the top of the wheel frame of the two casters 3. Two screws 11 spaced apart are welded to the top surface of the second crossbeam plate 8. A third crossbeam plate 9 is welded on the frame 1. Two sleeves 10 spaced apart are welded to the third crossbeam plate 9. The two sleeves 10 are respectively fitted onto the two screws 11, and the upper and lower ends of the sleeves 10 on each screw 11 are threaded with nuts. The two nuts can fix the screws 11 onto the sleeves 10 to prevent the screws 11 from moving up and down. This can fix the installation position of the second crossbeam plate 8 on the frame 1. The above structure makes the installation height of the two casters 3 on the frame 1 adjustable. By adjusting the installation height of the second crossbeam plate 8 on the frame 1, the height of the two casters 3 can be adjusted synchronously.

[0031] To accommodate farmers of different heights, the handle 6 is an adjustable telescopic rod structure; specifically, as shown... Figure 1 and Figure 2As shown, the handle 6 includes an outer tube 6.1 and an inner rod 6.2. A first crossbeam plate 7 is welded onto the frame 1. A hole plate for mounting bolts is welded to the middle of the first crossbeam plate 7. One end of the outer tube 6.1 is fixedly connected to the hole plate on the first crossbeam plate 7 by bolts. The tilt angle of the outer tube 6.1 can be adjusted by loosening the bolts. After adjustment, the bolts are retightened. One end of the inner rod 6.2 is threaded onto the other end of the outer tube 6.1. A pin 6.4 is threaded onto the outer wall of the other end of the outer tube 6.1. Multiple openings are spaced along the length of the inner rod 6.2. Each pin hole 6.3 has a locking pin 6.4. Tightening the pin 6.4 allows it to be inserted into one of the pin holes 6.3, locking the length of the overlapping section between the inner rod 6.2 and the outer tube 6.1. Unscrewing the pin 6.4 allows adjustment of the overlapping section length between the inner rod 6.2 and the outer tube 6.1. Inserting the pin 6.4 into the other pin hole 6.3 allows adjustment of the overall length of the handle 6. The other end of the inner rod 6.2 is welded with a handle perpendicular to it. The handle and the inner rod 6.2 form a T-shape, making it easy for farmers to hold the handle and drag the handle 6. The handle 6 with the above-mentioned telescopic rod structure is a conventional structure and is widely used in existing hand-pulled plows.

[0032] The working principle of the seeder in this embodiment is as follows: When this seeder is used for sowing in mountainous and hilly areas where large automated planting machinery cannot easily access the site, the seeder opens the cover 2.6 to pour the seeds into the hopper 2.1, then closes the cover 2.6. The farmer inserts the plow 4 into the ground, holds the handle 6 on the side away from the frame 1 with both hands, and drags the entire machine across the land to be sown. At the same time, the motor 2.7 is started by the switch on the handle, causing the motor 2.7 to drive the feed wheel 2.2 to rotate. When one of the grooves 2.2.1 on the outer wall of the feed wheel 2.2 rotates to the bottom of the hopper 2.1 and connects with it, the seeds in the hopper 2.1 fall into the groove 2.2.1 under gravity. The seed-filled groove 2.2.1 rotates clockwise along the inner side of the second baffle 2.5. Continue rotating until the seed-filled groove 2.2.1 rotates above the feed hopper 2.3. Without the obstruction of the second baffle 2.5, the seeds fall into the feed hopper 2.3 and then into the feed pipe 2.4. As the machine moves, the plow head 4 creates a trench in the ground. The seeds fall directly into the trench just created on the back side of the plow head 4 through the bottom of the feed pipe 2.4. As the plow head 4 continues to move, the soil between the plow head 4 and the two first baffles 5 is turned over from the top of the plow head 4 and falls into the trench on the back side of the plow head 4, thus covering the seeds in the trench. This seeder can complete trenching, seed placement, and soil covering in one step, making it suitable for automatic seed placement sowing operations in mountainous and hilly areas where large automated planting machinery cannot easily access the site.

[0033] This embodiment is based on the human-powered dragging and pulling of the whole machine to realize the agricultural sowing operation of digging ditches, placing seeds and covering soil in one step. In addition, existing micro-tillers powered by diesel or gasoline engines have been gradually developed and applied. After the handle 6 of the seeder of this application is removed, its frame 1 can be welded to the body of an existing micro-tiller, and the power of the existing micro-tiller can be used to drive the seeder, thereby saving manpower.
