Description

Technical Field

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

[0002] A seeder is a planting machine that uses crop seeds as the object of sowing. Seeders used for a certain type or type of crop are often named after the crop type, such as grain strip seeder, corn hill seeder, cotton seeder, and pasture spreader.

[0003] A novel multifunctional agricultural machinery seeder (publication number CN220123415U) is disclosed in an existing patent. This seeder includes a hopper, a housing, and a seeding disc. The seeding disc is rotatably mounted within the housing, and its circumference has multiple receiving slots for holding crop seeds. Because the outer circumferential surface of the seeding disc fits into the inner wall of the housing, a fixed quantity of seeds can be loaded into the receiving slots. During sowing, crop seeds are added to the hopper, and the seeding disc is rotated. The seeds fall into the receiving slots on the seeding disc through the outlet at the bottom of the hopper under gravity. The seed-filled receiving slots rotate with the seeding disc to the discharge port at the bottom of the housing, where the seeds fall out, thus performing a quantitative sowing operation.

[0004] While existing seeders have improved sowing efficiency, some problems exist during use. First, the existing design of the gap between the seed tray and the housing, while ensuring a quantitative load of conventional seeds, has poor compatibility with irregularly shaped seeds. Particularly with slender rice seeds that taper at both ends, flat angelica seeds, and small-diameter crop seeds, seeds easily become stuck in the gap between the seed tray and the housing during rotation, causing damage, affecting germination rate, and in severe cases, potentially causing the sowing mechanism to jam and stop. Second, different seeds require different amounts of seed per hole, and existing seeders cannot adjust the seed quantity, limiting the types of seeds they can sow. Utility Model Content

[0005] To address the aforementioned deficiencies, the technical problem to be solved by this invention is to provide an agricultural seeder that can quantitatively sow seeds and avoid damage to the seeds during the sowing process.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An agricultural seeder, comprising:

[0008] Frame;

[0009] The storage compartment is a circular compartment with a circumferential slide rail on its inner side. The storage compartment is rotatably mounted on a frame and has a first mounting opening along the axial direction.

[0010] A measuring spoon, wherein the measuring spoon is disposed in a slide, and several measuring spoons are provided along the length of the slide;

[0011] The material guide channel is fixedly connected to the frame. The outlet of the material guide channel is located outside the storage chamber. The inlet of the material guide channel passes through the first installation port and extends into the storage chamber. The inlet corresponds to the movement path of the measuring spoon. When the measuring spoon rotates with the storage chamber to above the inlet, the seeds located in the measuring spoon can be poured into the inlet.

[0012] By employing the above method, crop seeds are placed in a chute inside the storage chamber. Under the influence of gravity, the seeds tend to move towards the lowest point of the chute. During sowing, the storage chamber is rotated, and a measuring spoon scoops up the seeds. After the measuring spoon brings the seeds to above the feed inlet of the guide channel, the seeds slide out of the measuring spoon under the influence of gravity and fall into the guide channel. After entering the guide channel, the seeds fall into the soil through the discharge outlet, thus achieving quantitative sowing. As the storage chamber continues to rotate, the seeds move towards the lowest point of the chute under the influence of gravity, allowing the measuring spoon to carry the seeds out of the chute. Each time the measuring spoon scoops seeds, excess seeds fall off as the storage chamber rotates. The measuring spoon accurately dispenses the correct number of seeds each time, meeting the needs of quantitative sowing. This ensures sowing quality and effectiveness, and improves crop uniformity and yield. Furthermore, during the sowing process, the seeds are scooped out using a measuring spoon and fall into the feed channel under gravity. During this process, the seeds are not subjected to scraping or squeezing pressure from the movement of the seeder, which effectively avoids damage to the seeds, ensures the integrity of the seeds, and thus guarantees the germination rate.

[0013] Preferably, the storage chamber includes a first chamber and a second chamber, both of which are cylindrical basin-shaped. The first and second chambers are fastened together to form the storage chamber, and the first chamber has the first mounting opening. Because both the first and second chambers are cylindrical basin-shaped, the seeds in the storage chamber tend to gather towards the lowest point of the slide, making it easier to use a measuring spoon to scoop out the last bit of seeds from the storage chamber.

[0014] Preferably, the second compartment has a second mounting port corresponding to the first mounting port. Since the second compartment has a second mounting port corresponding to the first mounting port, the second compartment can be manufactured using the same mold used to manufacture the first compartment, thus reducing manufacturing costs.

[0015] Preferably, the first chamber has several first grooves along its upper circumferential direction, each corresponding to a measuring spoon; the second chamber has second grooves along its upper circumferential direction, each corresponding to a first groove. When the first and second chambers are fastened together, the first grooves and their corresponding second grooves assemble to form a mounting hole. A snap fastener is detachably connected to the mounting hole, and the measuring spoon is detachably connected to the snap fastener. The mounting hole facilitates the installation of the snap fastener, thus facilitating the installation of the measuring spoon. By replacing the measuring spoon with different sizes, the amount of seeds dispensed can be adjusted to meet the sowing requirements of different seeds.

[0016] Preferably, a slot is provided on one side of the buckle, and one end of the measuring spoon is engaged in the slot. The slot facilitates the connection between the measuring spoon and the buckle.

[0017] Preferably, the measuring spoon is sheet-shaped, and its length direction is inclined relative to the radial line of the circular container. Because the measuring spoon is sheet-shaped and its length direction is inclined relative to the radial line of the circular container, it can better scoop the seeds upwards, making it less likely for the seeds to fall off during feeding into the feed channel.

[0018] Preferably, the buckle has protrusions on opposite sides, and recesses in both the first and second grooves. Each recess corresponds to one of the protrusions, and the protrusion engages with its corresponding recess. After the buckle is inserted into the mounting hole, the protrusion engages with its corresponding recess, thus securing the buckle in the mounting hole. This enhances the buckle's stability and facilitates its installation and removal.

[0019] Preferably, a transmission wheel body is fixedly connected to the outer side of the second compartment. The transmission wheel body is coaxially arranged with the second compartment, and a rotating shaft is fixedly connected to the transmission wheel body. The rotating shaft is rotatably mounted on the frame, and a power source is provided on the frame. The output end of the power source is connected to the transmission wheel body. The second compartment is rotatably mounted on the frame via the transmission wheel body and the rotating shaft, allowing the storage compartment to rotate on the frame. The overall structure is simple and practical. The power source can drive the transmission body to rotate at a preset speed, thereby driving the storage compartment to rotate, which facilitates sowing.

[0020] Preferably, the transmission wheel body includes a first transmission wheel, a second transmission wheel, and a third transmission wheel connected to each other, with the diameters of the first, second, and third transmission wheels increasing sequentially. The power source is connected to one of the first, second, or third transmission wheels, which has a different diameter, allowing for gear adjustment and control of the rotation speed of the storage bin, thereby adjusting the sowing speed.

[0021] Preferably, the material guiding channel includes a material guiding trough and a material guiding cylinder connected together. The upper end of the material guiding trough extends into the first mounting port, and the width of the material guiding trough gradually increases from the lower end to the upper end. The lower end of the material guiding trough is connected to the material guiding cylinder, which is fixedly connected to the frame. The wider upper end of the material guiding trough ensures that the seeds in the measuring spoon can fall into the material guiding trough when passing over it.

[0022] In summary, the agricultural seeder provided by this utility model has at least the following beneficial effects:

[0023] 1. It can adapt to most seeds, regardless of their shape, avoiding damage to the seeds and effectively ensuring their integrity, thereby guaranteeing the germination rate.

[0024] 2. It enables precision sowing, ensuring sowing quality and effectiveness, and helps improve crop uniformity and yield.

[0025] 3. The overall structure is simple and the maintenance cost is low. Attached image description:

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-9 The present invention will be further described in detail below with reference to specific embodiments.

[0038] Example 1

[0039] Please see Figure 1-6 This embodiment provides an agricultural seeder, comprising: a frame 1, a storage bin 2, measuring spoons 4, and a material guide channel 5. The storage bin 2 is circular, with a circumferentially arranged slide rail on its inner side. The storage bin 2 is rotatably mounted on the frame 1. The slide rail is coaxial with the storage bin 2. A first mounting opening 3 is axially located on the right side of the storage bin 2. Several measuring spoons 4 are arranged within the slide rail, evenly distributed along its length. The specific number of measuring spoons 4 can be selected based on actual needs. With one measuring spoon 4, one rotation of the storage bin 2 results in one feeding; with two measuring spoons 4, two rotations result in two feedings, and so on. In this embodiment, eight measuring spoons 4 are preferably provided. The material guide channel 5 is fixedly connected to the frame 1, with its inlet located on the left and its outlet on the right, the inlet facing upwards. The discharge port of the material guide channel 5 is located outside the storage chamber 2, and the inlet of the material guide channel 5 passes through the first mounting port 3 and extends into the storage chamber 2. The inlet corresponds to the movement path of the measuring spoon 4. When the measuring spoon 4 rotates with the storage chamber 2 to above the inlet, the seeds located in the measuring spoon 4 can be poured into the inlet.

[0040] Please see Figure 2To facilitate manufacturing and assembly, the storage compartment 2 further includes a first compartment 201 and a second compartment 202, both of which are cylindrical basin-shaped. The first compartment 201 and the second compartment 202 are fastened together to form the storage compartment 2. The first compartment 201 is located to the right of the second compartment 202, and the two compartments are symmetrically arranged, having the same shape and size. A first mounting opening 3 is provided on the first compartment 201, and a second mounting opening 203 corresponding to the first mounting opening 3 is provided on the second compartment 202. After the first compartment 201 and the second compartment 202 are assembled, the inner wall of the area from the joint of the first compartment 201 and the second compartment 202 to the first mounting opening 3 and the second mounting opening 203 forms the aforementioned slide. The middle of the slide is the lowest point, and the cross-section of the slide is U-shaped. Both the first compartment 201 and the second compartment 202 have flanges 206 at their outer circumferential edges. When the first compartment 201 and the second compartment 202 are assembled together, the flanges 206 between the first compartment 201 and the second compartment 202 are connected together by bolts. The first compartment 201 and the second compartment 202 are symmetrically arranged and can be manufactured using the same mold. Both the first compartment 201 and the second compartment 202 are made of plastic.

[0041] Please continue reading. Figure 2 To facilitate the installation and removal of the measuring spoon 4, the first compartment 201 has several first grooves 204 corresponding to the measuring spoon 4 along its upper circumferential direction, and the second compartment 202 has second grooves 205 corresponding to the first grooves 204 along its upper circumferential direction. When the first compartment 201 and the second compartment 202 are fastened together, the first grooves 204 and the corresponding second grooves 205 fit together to form a mounting hole. A buckle 6 is detachably connected inside the mounting hole, and the measuring spoon 4 is detachably connected to the buckle 6. Specifically, the first groove 204 is located on the left side of the flange 206 of the first compartment 201, and the second groove 205 is located on the right side of the flange 206 of the second compartment 202.

[0042] Please see Figure 5 The right side of the clip 6 has a slot 7, into which the measuring spoon 4 is secured. The clip 6 is preferably made of plastic. In practical use, different sized measuring spoons 4 can be used to accommodate different seeds and sowing quantities. If the number of measuring spoons 4 needs to be reduced, several clips 6 can be removed, thus reducing the number of sowing cycles per rotation of the storage chamber 2 and adjusting the sowing spacing. The clip 6 can specifically employ a hollow structure to reduce material usage and manufacturing costs.

[0043] Please continue reading. Figure 5 and Figure 6The measuring spoon 4 is plate-shaped, and its length is inclined relative to the radial line of the circular container. Specifically, the measuring spoon 4 is made of rectangular iron sheet. The middle section of the measuring spoon 4 is engaged in the slot 7, one end of the measuring spoon 4 extends out of the inner wall of the storage container 2, and the other end of the measuring spoon 4 extends out of the outer wall of the storage container 2. In other embodiments, the measuring spoon 4 can also be U-shaped, V-shaped, or other shapes with a concave center, as long as the measuring spoon 4 can scoop up crop seeds during the rotation of the storage container 2.

[0044] Please continue reading. Figure 5 and Figure 6 To facilitate the installation and removal of the buckle 6, protrusions 8 are provided on opposite sides of the buckle 6, and recesses are provided in the first groove 204 and the second groove 205. The two recesses correspond one-to-one with the two protrusions 8, and the protrusions 8 are inserted into the corresponding recesses.

[0045] Please continue reading. Figure 3 To facilitate adjustment of the rotational speed of storage compartment 2, a transmission wheel body 9 is fixedly connected to the left side of the second compartment 202. The transmission wheel body 9 is coaxially arranged with the second compartment 202 and is fixedly connected to a rotating shaft. The rotating shaft is rotatably mounted on the frame 1, which is equipped with a power source. The output end of the power source is connected to the transmission wheel body 9. The power source can be a motor or other drive mechanism capable of driving the transmission wheel body 9 to rotate. The output end of the motor is connected to the transmission wheel body 9 via a belt 15. The transmission wheel body 9 is bolted to the second compartment 202. The transmission wheel body 9 is made of plastic and closes the second mounting port 203 on the second compartment 202. Specifically, the transmission wheel body 9 includes a first transmission wheel 901, a second transmission wheel 902, and a third transmission wheel 903 connected sequentially from left to right, with the diameters of the first transmission wheel 901, the second transmission wheel 902, and the third transmission wheel 903 increasing sequentially. In use, by connecting belt 15 to the first drive wheel 901, the second drive wheel 902, or the third drive wheel 903, the rotation speed of the storage chamber 2 can be easily adjusted, thereby adjusting the spacing between seed holes during sowing. In specific use, a motor or drive mechanism can be used as the power source, or the storage chamber 2 can be manually rotated to perform sowing operations.

[0046] Please continue reading. Figure 2The material guiding channel 5 includes a connecting material guiding trough 501 and a material guiding cylinder 502. The material guiding trough 501 is inclined to the upper left, and its upper end extends into the first mounting port 3. The width of the material guiding trough 501 gradually increases from the lower end to the upper end. The lower end of the material guiding trough 501 is connected to the material guiding cylinder 502, which is fixedly connected to the frame 1. To facilitate seed sowing, a material guiding pipe 10 is connected to the outlet of the material guiding channel 5. The seed is precisely guided through the material guiding pipe 10, thereby achieving the effect of precise sowing. Specifically, the material guiding pipe 10 can be a telescopic guide tube. During use, the lower end of the material guiding pipe 10 is kept at a distance of 5cm-10cm from the ground to prevent soil from sticking to the lower end of the material guiding pipe 10 during rain, which would affect the seed falling effect.

[0047] By adopting the above scheme, during use, crop seeds are placed in the slide inside the storage bin 2. Under the influence of gravity, the seeds tend to move towards the lowest point of the slide. During sowing, the storage bin 2 is rotated, and the measuring spoon 4 scoops up the seeds. At this time, the measuring spoon 4 tilts upwards, bringing the seeds to above the inlet of the guide channel 5. Then, the measuring spoon 4 tilts downwards, and under the influence of gravity, the seeds in the measuring spoon 4 slide down from above and fall into the guide channel 5. After entering the guide channel 5, the seeds fall into the soil through the outlet of the guide channel 5, thus achieving the effect of quantitative sowing. As the storage bin 2 continues to rotate, the seeds move towards the lowest point of the slide under the influence of gravity, allowing the measuring spoon 4 to carry the seeds out of the slide and return them to the lowest point of the slide. Each time the measuring spoon 4 scoops seeds, excess seeds will fall off as the measuring spoon 4 rotates with the storage bin 2. The measuring spoon 4 accurately dispenses the correct number of seeds each time, meeting the needs of quantitative sowing. This ensures sowing quality and effectiveness, improving crop uniformity and yield. Furthermore, during sowing, seeds are dispensed via a measuring spoon 4 and fall into the feed channel 5 under gravity. This process prevents small, flaky, and irregularly shaped seeds from being scraped or compressed by the seeder's movement, effectively avoiding seed damage and ensuring seed integrity, thus guaranteeing a high germination rate. In use, the entire device can be mounted on a carrier, which propels it forward. The spacing between sowing holes can be controlled by adjusting the carrier's speed. For example, it can be towed to a rotary tiller, which then drives the entire device for sowing.

[0048] Example 2

[0049] Please see Figure 7 and Figure 8Unlike the previous embodiment, in this embodiment, an axle is rotatably mounted on the frame, a wheel 13 is fixedly connected to the axle, and a pulley body 16 is fixedly connected to the axle. The pulley body 16 includes three pulleys, all of the same diameter and coaxially arranged, all fixedly connected to the axle. Each of the three pulleys corresponds to a first transmission wheel 901, a second transmission wheel 902, and a third transmission wheel 903. The pulley body 16 is connected to the transmission wheel body 9 via a belt 15. Specifically, one of the first transmission wheel 901, the second transmission wheel 902, or the third transmission wheel 903 may be connected to its corresponding pulley via a belt 15. The axle can be driven to rotate by a motor or other power mechanism. A height-adjustable trenching plowshare 12 is provided below the frame 1. Specifically, a telescopic rod is fixed to the frame 1, and the trenching plowshare 12 is fixedly connected to the lower end of the telescopic rod. The telescopic rod includes a fixed rod, a sleeve, a sliding rod, and an adjusting bolt. The fixed rod is fixedly connected to the lower side of the frame 1, the sleeve is fixedly connected to the fixed rod, the sliding rod passes through the sleeve, and the adjusting bolt is threaded onto the sleeve. One end of the adjusting bolt extends into the inside of the sleeve and abuts against the sliding rod, thereby fixing the sliding rod. The furrowing plow 12 is fixedly connected to the lower end of the sliding rod. By adjusting the length of the telescopic rod, the depth of the furrow opened by the furrowing plow is adjusted, thus adjusting the sowing depth. In use, the wheels 13 move forward along the sowing direction. The projection of the furrowing plow 12 on the horizontal plane is located in front of the discharge port of the discharge channel. By opening furrows on the cultivated land with the furrowing plow 12, the seeds in the storage bin 2 can be directly sown in the furrows, thus facilitating furrowing and sowing. To maintain the stability of the frame 1, two supports 11 are fixedly connected to the right end of the frame 1. The projections of the two supports 11 on the horizontal plane form a figure-eight shape. The support 11 includes a bent section 1101 and a horizontal section 1102. The horizontal section 1102 is the right section of the support 11, and it is at the same horizontal height as the lowest point of the wheel 13. The horizontal section 1102 can be columnar or plate-shaped. When sowing in paddy fields, the plate-shaped horizontal section 1102 can increase the support area, thereby providing better support for the overall equipment.

[0050] Example 3

[0051] Please see Figure 9Unlike the scheme in Embodiment 2, in this embodiment, a vehicle head 14 is hinged to the left end of the frame 1. The vehicle head 14 drives the frame 1 forward and facilitates turning. The vehicle head 14 includes a frame, a power mechanism, and two front wheels, which are rotatably mounted under the frame. A rotating shaft is rotatably connected to the frame 1, and wheels 13 are fixedly connected to both ends of the rotating shaft. Pulley bodies 16 are fixedly connected to both ends of the rotating shaft. Two storage compartments 2 are rotatably mounted on the frame, and the two storage compartments 2 correspond one-to-one with the two pulley bodies 16. The pulley bodies 16 are connected to the corresponding transmission wheel bodies 9 on the storage compartment 2 via belts 15. Since the overall structure can be stably supported on the ground, no support 11 is required on the frame 1.

[0052] In other embodiments, to achieve simultaneous sowing of multiple rows, multiple storage bins 2 can be installed on the frame. In use, a drive mechanism such as a motor drives multiple storage bins 2 to rotate simultaneously for synchronous sowing.
