[0002] A seeder is a planting machine that uses crop seeds as the sowing object. According to its structure, it can generally be divided into roller seeders, pneumatic seeders, and air-suction seeders. An air-suction seeder is an agricultural machine that uses vacuum suction to control seed transportation and sowing. An air-suction seeder generally includes a seed box, a seed suction tray, a vacuum system, and a seed release mechanism. The seed box is used to store seeds to be sown. The seed suction tray is one of the core components of the air-suction seeder. It is usually a rotating disk or wheel with multiple small holes. When the seed suction tray rotates, vacuum suction will absorb the seeds through these small holes. The vacuum system includes a vacuum pump or fan, and a pipe connected to the seed suction tray to generate the necessary vacuum suction. The seed release mechanism is responsible for releasing the seeds from the seed suction tray to the sowing port at the right time.

[0036] A seeder is a planting machine that uses crop seeds as the sowing object. According to its structure, it can generally be divided into roller seeders, pneumatic seeders, and air-suction seeders. An air-suction seeder is an agricultural machine that uses vacuum suction to control seed transportation and sowing. An air-suction seeder generally includes a seed box, a seed suction tray, a vacuum system, and a seed release mechanism. The seed box is used to store seeds to be sown. The seed suction tray is one of the core components of the air-suction seeder. It is usually a rotating disk or wheel with multiple small holes. When the seed suction tray rotates, vacuum suction will absorb the seeds through these small holes. The vacuum system includes a vacuum pump or fan, and a pipe connected to the seed suction tray to generate the necessary vacuum suction. The seed release mechanism is responsible for releasing the seeds from the seed suction tray to the sowing port at the right time.

[0037] The air-suction seeder generally adjusts the spacing between seeds by adjusting the rotation speed of the seed suction disk, that is, by adjusting the rotation speed of the seed suction disk, the number of seeds delivered per unit time is controlled, thereby affecting the distance between seeds.

[0038] However, the method of adjusting the distance between seeds by adjusting the rotation speed of the seed suction plate can only roughly adjust the distance between seeds, and cannot meet the demand for more accurate adjustment of the distance between seeds.

[0039] In order to solve the above technical problems, the embodiments of the present disclosure provide a supporting contour structure, a seed suction tray, a seeder and a seeder, which can more accurately adjust the distance between seeds.

[0040] Example 1

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, a supporting contour structure includes a bearing part 1, a tray 2 and an adjustable spacing buckle 3, the inner wall of the bearing part 1 encloses a accommodating space, one side of the bearing part 1 is provided with an opening, and the accommodating space is connected to the opening; a plurality of trays 2 are provided, and the plurality of trays 2 are arranged in parallel and spaced apart in the accommodating space, the plurality of trays 2 are slidably connected to the inner wall of the bearing part 1, and a vacuum adsorption hole is provided in the tray 2; a plurality of adjustable spacing buckles 3 are provided, and the adjustable spacing buckles 3 include a first connecting part 31, a second connecting part 32 and a locking mechanism 33, the first connecting part 31 and the second connecting part 32 are respectively connected to two adjacent trays 2, the first connecting part 31 and the second connecting part 32 are slidably connected, a locking mechanism 33 is provided at the connection between the first connecting part 31 and the second connecting part 32, and the distance between the ends of the first connecting part 31 and the second connecting part 32 is adjustable.

[0042] The bearing part 1 is the basic component of the entire supporting contour structure. It provides support for other components and forms a closed or semi-closed space to accommodate the tray 2 and other items. The bearing part 1 can be circular, rectangular or square. The rectangular or square structure is easy to manufacture and can effectively utilize the space when placing multiple parallel and spaced trays 2. The rectangular or square design also makes it easy for the bearing part 1 to be used in conjunction with other equipment or storage units. The inner wall of the bearing part 1 encloses a storage space for placing the tray 2 and other items. The inner wall can be upright and smooth, or it can be designed in different shapes. An opening is provided on one side of the bearing part 1 to facilitate the entry and exit of the tray 2 and the placement of items. The size and position of the opening can be designed according to actual needs. Specifically, it can be a larger top opening to facilitate the seeds to fall into the tray 2. The storage space is an area enclosed by the inner wall of the bearing part 1, which is used to place multiple parallel and spaced trays 2. The size of the storage space determines how many trays 2 can be accommodated and the size of the tray 2. More specifically, the material of the bearing part 1 can be metal or plastic, for example, it can be 7075 aluminum alloy.

[0043] The tray 2 is a structure for carrying and fixing seeds. Specifically, the tray 2 can be rectangular or square, so that the space in the bearing part 1 can be effectively utilized. According to actual needs, the shape of the tray 2 can also be other geometric shapes, such as round or oval, to accommodate seeds of different shapes. In order to improve the adsorption effect and durability, the surface of the tray 2 may be specially treated, such as coating or polishing, to ensure that the surface is flat and defect-free. The material of the tray 2 needs to be selected from a material that will not cause damage to the seeds and has a certain degree of durability. More specifically, the material of the tray 2 can be selected from plastics and metals. For example. It can be polycarbonate, POM (polyoxymethylene), etc.

[0044] Specifically, a groove can be provided in the center of the tray 2, and the shape of the groove can be adapted to the shape of the seed. For example, if the seed is round or approximately round, the groove can be designed to be round; if the seed is flat or irregular in shape, a flat or irregular groove shape needs to be designed to match. The size of the groove should be slightly larger than the actual size of the seed to ensure that the seed can be easily placed and remain stable, but not too large to cause the seed to shake in the groove. The depth of the groove can cover more than half of the seed, so that the seed can be effectively fixed to prevent it from falling off due to vibration during transportation.

[0045] Specifically, the vacuum adsorption hole is a small hole provided on the tray 2 in the supporting contour structure, which is used to connect the vacuum system to adsorb and fix the items placed on the tray 2. This design can ensure that the items remain stable during transportation or processing, reducing the risk of movement or falling. When the vacuum system is started, the air near the adsorption hole is evacuated to form a negative pressure area. The items placed on the tray 2 will be pressed against the surface of the tray 2 by the atmospheric pressure, thereby being fixed in place. When the vacuum system is turned off, the atmospheric pressure balance is restored, and the items can be easily removed from the tray 2. The vacuum adsorption holes need to be evenly distributed on the surface of the tray 2 to ensure that the items are subjected to uniform pressure. More specifically, the vacuum adsorption holes can be set around the groove or at the bottom of the groove to ensure that the seeds are firmly adsorbed. More specifically, the vacuum adsorption holes are connected to the vacuum generator through a pipe or a hose.

[0046] The adjustable spacing buckle 3 is a component in the supporting contour structure used to adjust the distance between adjacent trays 2. In the unadjusted state, the adjustable spacing buckle 3 fixes two adjacent trays 2 at a preset distance. When adjusting, the user can loosen the locking mechanism 33 and then change the distance between them by pushing or pulling the first connection part 31 and the second connection part 32. After adjusting to the desired distance, re-lock the locking mechanism 33 to fix the position. Once the desired distance is reached, the locking mechanism 33 can ensure that the position of the first connection part 31 and the second connection part 32 will not change due to external forces.

[0047] Specifically, the first connection part 31 and the second connection part 32 are important components of the adjustable spacing buckle 3, which are responsible for connecting adjacent trays 2 and allowing the distance between the trays 2 to be adjusted. More specifically, the first connection part 31 and the second connection part 32 can be fixedly connected to the tray 2, or can be detachably connected to the tray 2. More specifically, the first connection part 31 and the second connection part 32 can be bolted to the tray 2; more specifically, one end of the first connection part 31 or the second connection part 32 is connected to the tray 2 by bolts, and the bolts pass through the holes on the tray 2 and cooperate with the threaded holes or nuts on the first connection part 31. The first connection part 31 and the second connection part 32 can be bolted to the tray 2 or connected to the tray 2 by buckles. For example, one end of the first connection part 31 or the second connection part 32 is designed with a buckle or a hook, which can be directly snapped into the corresponding notch on the tray 2. The slider 5 can also be fixedly connected to the side wall of the tray 2, and the buckle or hook is snapped into the side wall of the slider 5 to complete the snap connection. The first connection part 31 and the second connection part 32 can also be connected to the tray 2 by a pin or a hinge. As long as the first connection part 31 and the second connection part 32 can be connected to the tray 2, the specific connection structure between the first connection part 31 and the second connection part 32 and the tray 2 is not limited.

[0048] The connection between the first connection part 31 and the second connection part 32 is a key part in the design of the adjustable spacing buckle 3, which allows the user to adjust the distance between the trays 2. Specifically, the first connection part 31 and the second connection part 32 can be connected by a slide rail 4 and a slider 5. For example, a slide rail 4 can be set on the first connection part 31, and a plurality of positioning holes or grooves can be set on the slide rail 4; a slider 5 matching the slide rail 4 of the first connection part 31 is set on the second connection part 32, and a pin or a protrusion is set on the slider 5, which can be inserted into the positioning hole or groove of the slide rail 4. The second connection part 32 is moved along the slide rail 4 by sliding until the pin or protrusion is inserted into a suitable positioning hole or groove. A locking mechanism 33 (such as a knob, a screw, etc.) is used to lock the position of the pin or protrusion to prevent accidental movement during use. The first connection part 31 and the second connection part 32 can also be threadedly connected. For example, a threaded hole can be set on the first connection part 31, and an adjustment rod with an external thread can be set on the second connection part 32, which can be screwed into the threaded hole of the first connection part 31. The distance between the first connection part 31 and the second connection part 32 is adjusted by rotating the adjustment rod. The adjusted distance is locked by the adjustment rod itself or by an additional locking mechanism 33 (such as a locking nut). The first connection part 31 and the second connection part 32 can also be connected by a gear rack; for example, a gear can be provided on the first connection part 31, and a rack meshing with the gear can be provided on the second connection part 32, and the rack can slide along the straight line direction of the first connection part 31. The rack is driven to slide by rotating the gear, thereby adjusting the distance. The position of the rack is locked by a locking mechanism 33 (such as a spring clip or a knob). The first connection part 31 and the second connection part 32 can also be connected in a telescopic manner; specifically, a telescopic tubular structure can be provided on the first connection part 31, and a sleeve matching the tubular structure of the first connection part 31 can be provided on the second connection part 32, and the sleeve can slide along the tubular structure. The distance is adjusted by stretching or compressing the tubular structure between the first connection part 31 and the second connection part 32. The position of the tubular structure is locked by a locking mechanism 33 (such as a button or a knob). As long as the positions of the ends between the first connection portion 31 and the second connection portion 32 are adjustable, the specific structures of the first connection portion 31 and the second connection portion 32 are not limited.

[0049] The first connection part 31 and the second connection part 32 are respectively connected to two adjacent trays 2. For example, every two trays 2 are connected by the first connection part 31 and the second connection part 32. Figure 1As shown, not only the two trays 2 on both sides are connected by the first connection part 31 and the second connection part 32, but also the two trays 2 in the middle are connected by the first connection part 31 and the second connection part 32 of another adjustable spacing buckle 3. That is, the four trays 2 are connected by three adjustable spacing buckles 3 to achieve adjustable distance between every two trays 2. The first connection part 31 and the second connection part 32 are respectively connected to two adjacent trays 2. Figure 1 As shown, only two trays 2 on both sides are connected by the first connection part 31 and the second connection part 32, and the driving end of the driving member 6 is connected to any one of the two adjacent trays 2 connected by the first connection part 31 and the second connection part 32, and the two driving members 6 drive the trays 2 to move, so as to adjust the distance between the two trays 2 that are not connected by the adjustable spacing buckle 3. For example, Figure 1 The distance between the two middle trays 2.

[0050] Through the above technical solution, the supporting contour structure provided by the present invention supports seeds through the tray 2, and is respectively connected to every two adjacent trays 2 through the first connection part 31 and the second connection part 32 of the adjustable spacing buckle 3, and the first connection part 31 and the second connection part 32 are movably connected, so that the distance between the ends of the first connection part 31 and the second connection part 32 can be adjusted and the adjusted position is locked by the locking mechanism 33, thereby adjusting the distance between every two adjacent trays 2, thereby meeting the demand for more precise adjustment of the distance between seeds.

[0051] In some embodiments, the first connecting portion 31 is formed by connecting the first connecting rod 311, the first curved rod 312 and the second connecting rod 313 in sequence; the second connecting portion 32 is formed by connecting the third connecting rod 321, the second curved rod 322 and the fourth connecting rod 323 in sequence; the bending directions of the first curved rod 312 and the second curved rod 322 are opposite, the ends of the first connecting rod 311 and the third connecting rod 321 are connected and on the same straight line, and the ends of the second connecting rod 313 and the fourth connecting rod 323 are spaced apart by a set distance. The first connecting rod 311, the first curved rod 312 and the second connecting rod 313 can be split structures or formed by bending a single rod; similarly, the third connecting rod 321, the second curved rod 322 and the fourth connecting rod 323 can be split structures or formed by bending a single rod. When in use, a tray 2 or a slider 5 connected to a tray 2 can enter the adjustable spacing buckle 3 from the gap between the ends of the second connecting rod 313 and the fourth connecting rod 323 and be clamped at the first curved rod 312, and then the adjustable spacing buckle 3 is rotated around the slider 5 or the first tray 2, and enters another tray 2 or the slider 5 connected to the tray 2 at the gap, thereby realizing the detachable connection between the adjustable spacing buckle 3 and the slider 5 or the first tray 2 and the slider 5 and the second tray 2, and facilitating the replacement of the buckle. The first curved rod 312 and the second curved rod 322 are clamped on the tray 2 or the slider 5 connected to the tray 2 to improve the stability of the connection.

[0052] In some embodiments, the end of the second link 313 is disposed on a side of the fourth link 323 close to the third link 321, and the second link 313 and the fourth link 323 partially overlap in the projection direction of the first link 311. Figure 2 As shown, the end of the second connecting rod 313 is arranged directly below the fourth connecting rod 323. When in use, the tray 2 or the slider 5 connected to the tray 2 can enter the adjustable spacing buckle 3 from the gap between the end of the second connecting rod 313 and the fourth connecting rod 323. The end of the second connecting rod 313 is arranged on the side of the fourth connecting rod 323 away from the third connecting rod 321, and the second connecting rod 313 and the fourth connecting rod 323 partially overlap in the projection direction of the first connecting rod 311, so that the tray 2 can be prevented from coming out of the gap when in use, and the stability of the connection is ensured.

[0053] In some embodiments, the first connecting rod 311 is inserted into the third connecting rod 321, and an adjusting bolt is provided at the connection between the first connecting rod 311 and the third connecting rod 321, and the adjusting bolt abuts against the first connecting rod 311; a scale 34 is provided at the connection between the first connecting rod 311 and the third connecting rod 321, and the scale 34 extends along the plugging direction of the first connecting rod 311 and the third connecting rod 321. Specifically, a long strip through hole can be provided on the outer side of the connection between the third connecting rod 321 and the first connecting rod 311, and the adjusting bolt is provided in the through hole, and a scale 34 line is provided at the top of the through hole, and the scale 34 line is aligned with the end of the first connecting rod 311 to accurately adjust the insertion depth of the first connecting rod 311 in the third connecting rod 321, thereby adjusting the distance between the trays 2. After adjusting to the desired distance, the position of the first connecting rod 311 in the third connecting rod 321 is locked by tightening the adjusting bolt to ensure that the distance between the trays 2 remains unchanged during use.

[0054] In some embodiments, a slide rail 4 is provided on the inner wall of the bearing portion 1, a slider 5 is provided on the side wall of the tray 2, the slider 5 is slidably connected to the slide rail 4, and the first connection portion 31 and the second connection portion 32 are connected to the slider 5. On the one hand, the slide rail 4 and the slider 5 are provided to improve the stability of the sliding connection. On the other hand, the slider 5 can also facilitate the connection with the first connection portion 31 and the second connection portion 32 of the adjustable spacing buckle 3. Specifically, the slider 5 can be square-shaped or cylindrical, and the cylindrical shape can better connect with the first curved rod 312 and the second curved rod 322. More specifically, the slider 5 can be a connecting sliding bolt.

[0055] In some embodiments, the driving member 6 , a driving end of the driving member 6 is connected to any one of two adjacent trays 2 connected to the first connecting portion 31 and the second connecting portion 32 .

[0056] like Figure 1 As shown, when only two trays 2 on both sides are connected by the first connection part 31 and the second connection part 32, the distance between adjacent trays 2 that are not connected by the adjustable spacing buckle 3 can be adjusted by the driving member 6. Specifically, the distance between the trays 2 that are not connected by the adjustable spacing buckle 3 and the distance between the trays 2 connected by the adjustable spacing buckle 3 can be made the same by the cylinder driving member 6 to achieve equal spacing planting. When planting seeds of different varieties or seeds with non-equal spacing, the distance between adjacent trays 2 that are not connected by the adjustable spacing buckle 3 can be adjusted online by the driving member 6 to meet the planting requirements of different seeds.

[0057] In some embodiments, the driving member 6 is a bidirectional slide cylinder. Specifically, the bidirectional slide cylinder can be a cylinder with a one-way stroke of 50 mm and open and closed at both ends. Compared with the electric cylinder, the bidirectional slide cylinder usually has a more compact structure, which helps to save space. Compared with the method of directly using multiple electric cylinders to drive each tray 2, the driving method of using the bidirectional slide cylinder and the adjustable spacing buckle 3 can save half of the driving member 6, save costs and optimize the structural space.

[0058] A support column is provided on one side of the bearing part 1, and one end of the support column is detachably connected to the base 8. The base 8 is used to connect the adapter plate of the automatic seeding machine, and can be positioned through multiple holes, and can also be provided with a variety of bolt holes to be bolted to the support column. More specifically, the material of the base 8 can be selected from SUS304 stainless steel. The support column mainly plays a supporting role, and has threads at both ends, which are respectively bolted to the bearing part 1 and the base 8.

[0059] Example 2

[0060] A seed suction tray comprises the supporting contour structure as described in Embodiment 1. The supporting contour structure is installed on the outer circumference of the seed suction tray and can rotate with the rotation of the seed suction tray, thereby achieving sowing.

[0061] Through the above technical solution, the supporting contour structure provided by the present invention supports seeds through the tray 2, and is respectively connected to every two adjacent trays 2 through the first connection part 31 and the second connection part 32 of the adjustable spacing buckle 3, and the first connection part 31 and the second connection part 32 are movably connected, so that the distance between the ends of the first connection part 31 and the second connection part 32 can be adjusted and the adjusted position is locked by the locking mechanism 33, thereby adjusting the distance between every two adjacent trays 2, thereby meeting the demand for more precise adjustment of the distance between seeds.

[0062] Example 3

[0063] A seeder includes the seed suction tray as described in Example 2. The seeder may also include a seed box, a vacuum system, and a seed release mechanism. The seed box is connected to the seed suction tray and is used to store seeds to be sown. The vacuum system includes a vacuum pump or a fan, and a pipe connected to the vacuum adsorption hole in the seed suction tray to generate the necessary vacuum suction force.
