Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural equipment, and in particular relates to an intelligent centrifugal seeder. Background Art

[0002] Intercropping wheat and legumes is a core model of modern agriculture: the nitrogen fixation of legume roots provides natural nitrogen fertilizer for wheat, reducing the need for chemical fertilizers. At the same time, the staggered growth structure of tall legumes and short wheat improves the photosynthetic efficiency of the colony. Although intercropping has these advantages, completely mixing wheat and legumes will cause great inconvenience during the subsequent harvesting process, so regular planting is necessary. At the same time, traditional mechanical seeders only support single seed sowing and cannot achieve dual-crop strip distribution. Furthermore, there are synchronous strip seeders in the existing technology. Although they can complete dual-crop sowing in a single pass, they rely on pneumatic adsorption, have poor adaptability to heavy bean seeds, high energy consumption, and complex structure and high cost. Centrifugal sowing can effectively avoid the above problems by utilizing the different gravity of different seeds to throw the seeds to different distances. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide an intelligent centrifugal seeder that can regularly plant beans and wheat between crops, ensure planting effects, and facilitate harvesting.

[0004] An intelligent centrifugal seeder includes a fixed sleeve, which is rotatably connected to a feeding tube, a vertical rod connected to the lower side of the feeding tube, a frustum connected to the vertical rod, a rotating tube fixedly connected to the lower side of the frustum, an inner centrifugal chassis fixedly connected to the inner centrifugal chassis, an outer centrifugal chassis fixedly connected to the middle centrifugal chassis, a plurality of side plates fixedly connected to the rotating tube, and an extension plate connected to each side plate.

[0005] A cylindrical rod is fixedly connected to each of the extension plates. A collar is rotatably connected to the adding tube. A plurality of toggle slot rods are fixedly connected to the collar. The plurality of toggle slot rods are respectively sleeved on the plurality of cylindrical rods.

[0006] Each of the extension plates is provided with an oblique guide groove.

[0007] An auxiliary plate is fixedly connected to each of the extension plates.

[0008] The beneficial effects of this equipment are: Wheat seeds and bean seeds can be planted in the same field, and the interaction between plants can be used to improve the planting effect. Under the premise of reducing the use of fertilizers, wheat seeds and bean seeds can still be regularly distributed in the same field, forming multiple overall planting distributions consisting of wheat on the left, beans in the middle, and wheat on the right, which brings convenience to subsequent harvesting.

DETAILED DESCRIPTION

[0011] An intelligent centrifugal seeder includes a fixed sleeve 101, to which an addition tube 102 is rotatably connected. The lower side of the addition tube 102 is connected to a vertical rod, to which a frustum 302 is connected. The lower side of the frustum 302 is fixedly connected to a rotating tube 301, the lower side of the rotating tube 301 is fixedly connected to an inner centrifugal chassis 401, the inner centrifugal chassis 401 is fixedly connected to a middle centrifugal chassis 402, the middle centrifugal chassis 402 is fixedly connected to an outer centrifugal chassis 403, and a plurality of side plates 501 are fixedly connected to the rotating tube 301, each side plate 501 is connected to an extension plate 502.

[0012] The fixing sleeve 101 is connected to a vehicle capable of carrying the fixing sleeve 101 by screwing bolts into the fixing sleeve 101, and the vehicle is connected to other agricultural machinery capable of turning and burying the soil to provide a suitable environment for subsequent sowing. Such machinery has been widely used in reality and will not be described in detail here. The wheat seeds are gradually added into the adding tube 102 by using a container with its own power source and the opening can be opened intermittently. The adding tube 102 can guide the wheat seeds so that the wheat seeds gradually fall onto the cone 302, and then the wheat seeds will fall between the multiple side plates 501 along the cone 302. The cone 302 pre-distributes the seeds to avoid congestion caused by concentrated falling. During this process, the adding tube 102 is operated to rotate continuously on the fixed sleeve 101, so that the adding tube 102 drives the vertical rod, and the vertical rod drives the cone 302, so that the cone 302, the rotating tube 301, the side plate 501, the extension plate 502, the inner centrifugal chassis 401, the middle centrifugal chassis 402 and the outer centrifugal chassis 403 are continuously rotating. After the wheat seeds fall between the multiple side plates 501, the continuous rotation of the rotating tube 301 will gradually subject the wheat seeds to centrifugal force. At this time, due to the light weight and small inertia of the wheat seeds themselves, the centrifugal force will be stronger, so that the seeds can slide along the multiple side plates 501. After sliding to the farthest distance of the multiple extension plates 502, they can be gradually guided by the multiple extension plates 502 and finally gradually fall from the slot space between the middle centrifugal chassis 402 and the outer centrifugal chassis 403. As a result, the wheat seeds can be planted in an area farther away from the center of the adding tube 102 during centrifugal sowing. When it is necessary to plant bean crops, the carrier is moved again along the previously traveled path. At this time, bean seeds are gradually added to the addition tube 102. Then, the above rotation process is repeated to perform the centrifugal sowing operation. During the centrifugal sowing operation, due to the heavy weight and large inertia of the bean seeds themselves, the centrifugal effect is weak. At the same time, due to the obstruction of multiple inclined extension plates 502, the bean seeds cannot slide a long distance, and the bean seeds fall along the slot space between the middle centrifugal chassis 402 and the inner centrifugal chassis 401. As a result, the bean seeds can be planted in an area close to the center of the addition tube 102 during centrifugal sowing. The extension plates 502 restrict the sliding range of the seeds to ensure that the heavy bean seeds will not overflow due to inertia. Wheat seeds and bean seeds can be planted in the same field, and then the interaction between plants can be used to improve the planting effect. Under the premise of reducing the use of fertilizers, wheat seeds and bean seeds can still be regularly distributed in the same field, forming multiple overall planting distributions formed by wheat on the left, beans in the middle, and wheat on the right, which brings convenience to subsequent harvesting. The nitrogen fixation of beans provides nitrogen for wheat, reducing the use of chemical fertilizers. The tall beans and short wheat grow in staggered layers, which improves the photosynthetic efficiency of the group. At the same time, due to centrifugal sowing, there will be a part of the middle bean belt reserved space in the middle of the beans on the lower side of the inner centrifugal chassis 401. This space can be laid with a drip irrigation belt to realize water and fertilizer integration, that is, while ensuring the natural interaction effect between plants, it can also facilitate subsequent harvesting operations.

[0013] A cylindrical rod 503 is fixedly connected to each of the extension plates 502 . A collar 201 is rotatably connected to the adding tube 102 . A plurality of toggle slot rods 202 are fixedly connected to the collar 201 . The plurality of toggle slot rods 202 are respectively sleeved on the plurality of cylindrical rods 503 .

[0014] During wheat sowing, the collar 201 can be rotated on the adding tube 102 according to the type of wheat seeds or the degree of weight increase caused by the moisture of the wheat seeds themselves, so that the collar 201 drives the multiple toggle slot rods 202 to rotate, and then the multiple toggle slot rods 202 to toggle the multiple extension plates 502 on the multiple side plates 501 to rotate, so that the inclination angles of the multiple extension plates 502 change, thereby increasing or reducing the guiding resistance encountered by the wheat seeds during centrifugal sowing, and then selecting a suitable force between low resistance to ensure smooth sliding of the seeds and high resistance to reduce seed collision energy and reduce wheat breakage rate, which brings convenience to actual sowing; During the sowing of bean seeds, the angle between the multiple extension plates 502 and the side plates 501 can be gradually reduced by rotating the operating ring 201 on the adding tube 102 until the multiple extension plates 502 are interlocked with each other, thereby preventing the bean seeds from entering the slot space between the middle centrifugal chassis 402 and the inner centrifugal chassis 401, further ensuring the subsequent regular area sowing effect.

[0015] Each of the extension plates 502 is provided with an oblique guide groove 504 .

[0016] When the wheat seeds are centrifuged onto the extension plate 502, as the wheat seeds continue to move forward, they will be gradually guided by the oblique guide groove 504. The farthest distance that the wheat seeds can move under the guidance of the oblique guide groove 504 is the farthest and lowest position of the extension plate 502. The wheat seeds will then fall out from this position, thereby ensuring that the wheat seeds will not be centrifuged too far or thrown at too high an angle, further ensuring the subsequent regular area sowing effect. The collision process between the seeds and the oblique guide groove 504 consumes part of the kinetic energy and reduces the bounce height. The oblique guide groove 504 can reduce the seed ejection angle and prevent the seeds from flying out of the predetermined sowing belt. That is, the oblique guide groove ensures that the wheat seeds strictly fall between the median centrifugal chassis 402 and the outer centrifugal chassis 403, reducing the lateral error of the landing point, ensuring that the wheat can form a stable bandwidth with the inner circle of the bean sowing, and meeting the passage requirements of the combine harvester's belt-splitting operation.

[0017] An auxiliary plate 505 is fixedly connected to each of the extension plates 502 .

[0018] The auxiliary plate 505 can block the farthest and lowest position of the extension plate 502, so that the wheat seeds can be blocked by the auxiliary plate 505 after reaching this position, and thus fall smoothly from the position, further avoiding the situation where the wheat seeds are too far away from the centrifugal force, and ensuring a neat and regular sowing effect.

[0019] The rotating tube 301 is hollow and has a plurality of through holes.

[0020] A hose for passing air is connected to the underside of the inner centrifugal chassis 401 and inserted into the rotating tube 301. During centrifugal operation, air is passed through the hose into the rotating tube 301. The air is then ejected from the multiple through holes, thereby blowing away beans that are too large or too heavy to be moved smoothly by centrifugal force alone. This allows the beans to fall smoothly through the slot space between the inner centrifugal chassis 401 and the middle centrifugal chassis 402, ensuring normal sowing operations. At the same time, intermittent high-pressure airflow can be used to impact seed clumps, further reducing clogging rates. At the same time, when there are many steep slopes, the density of the through holes on the lower side of the rotating tube 301 is increased to offset the seed accumulation caused by the gravity component.

[0021] The central centrifugal chassis 402 is provided with a conical surface portion 404 , which gradually decreases from the outside to the inside.

[0022] The setting of the connecting threaded hole 405 allows the operation of the adding tube 102 to be stopped periodically during centrifugal sowing of beans. At this time, the bean seeds that are centrifuged too far and fall on the middle centrifugal chassis 402 will continue to slide along the conical surface portion 404 to the slot space between the inner centrifugal chassis 401 and the middle centrifugal chassis 402, thereby smoothly entering the predetermined sowing space for sowing, further ensuring the smooth progress of the sowing operation.

[0023] The central centrifugal chassis 402 is provided with a plurality of connecting threaded holes 405 .

[0024] When sowing wheat seeds, a cover plate can be connected to the lower side of the central centrifugal chassis 402 by screwing bolts into multiple connecting threaded holes 405, and then the cover plate is used to block the slot space between the inner centrifugal chassis 401 and the central centrifugal chassis 402, thereby ensuring that subsequent wheat seeds can smoothly pass through the slot space between the inner centrifugal chassis 401 and the central centrifugal chassis 402, providing stable protection for subsequent regular area sowing operations.

[0025] It also includes a connecting ring 701 fixedly connected to the upper side of multiple side plates 501, multiple longitudinal rods 702 are fixedly connected to the connecting ring 701, a moving frame 601 is slidably connected between the multiple longitudinal rods 702, a baffle 602 is fixedly connected to the moving frame 601, a cross bar 603 is fixedly connected between two longitudinal rods 702 located on the rear side among the multiple longitudinal rods 702, an L-shaped rod 606 is fixedly connected to the moving frame 601, a compression spring is fixedly connected between the L-shaped rod 606 and the cross bar 603, the frustum 302 is slidably connected to the vertical rod, and a tension spring is fixedly connected between the frustum 302 and the vertical rod.

[0026] Under normal circumstances, the compression spring makes the baffle 602 rest against the adding tube 102. During the sowing period, if a large amount of seeds are accumulated on the inner centrifugal chassis 401, the middle centrifugal chassis 402 and the outer centrifugal chassis 403, the cone 302 will slide downward on the vertical rod against the elastic force of the tension spring. When the cone 302 continues to move downward until the baffle 602 is offset from the adding tube 102, the maximum amount of seeds that can be stored on the inner centrifugal chassis 401 is reached. At this time, the movable frame 601 will be subjected to the elastic force of the compression spring to slide the baffle 602 to block the lower side of the adding tube 102, thereby stopping the seed adding operation of the adding tube 102, while the adding tube 102 continues to rotate, so that the seeds stored on the inner centrifugal chassis 401 can be quickly thrown out without subsequent addition, thereby clearing out the excessively accumulated seeds and ensuring the stable operation of the equipment. Furthermore, a displacement sensor can be connected to a longitudinal rod 702, and the moving end of the displacement sensor can be fixed to the moving frame 601. When the moving end of the displacement sensor moves, the displacement sensor can receive a sliding signal from the moving frame 601, and then transmit the signal to the front device, thereby synchronously stopping the addition of seeds into the adding tube 102 to avoid seed overflow.

[0027] The device further comprises a T-shaped rod 604 fixedly connected to the crossbar 603 , a rectangular plate 605 being slidably connected to the T-shaped rod 604 , and an electric push rod being fixedly connected to the T-shaped rod 604 and capable of pushing the rectangular plate 605 to slide.

[0028] When seed addition is stopped for a period of time, the rectangular plate 605 slides on the T-bar 604, and then the rectangular plate 605 pushes the movable frame 601 to overcome the compression spring and return to the left. When the baffle 602 is completely offset from the addition tube 102, the tension spring will pull the cone 302 to return upward, thereby performing subsequent sowing operations.

[0029] It also includes a connecting piece 104 fixedly connected to the addition pipe 102, and a mating gear 106 is connected to the connecting piece 104. The mating gear 106 can rotate around a virtual axis. A mating gear ring 105 and a driving gear ring 103 are fixedly connected to the addition pipe 102, and the mating gear 106 is engaged with the mating gear ring 105. A motor A capable of driving the mating gear 106 to rotate is fixedly connected to the connecting piece 104, and a motor B is fixedly connected to the fixed sleeve 101. A driving gear is fixedly connected to the output shaft of the motor B, and the driving gear is engaged with the driving gear ring 103.

[0030] By starting motor B, the driving gear drives the driving gear ring 103 to rotate, and then the adding tube 102 rotates to complete the subsequent centrifugal seeding operation. When the inclination angle of multiple extension plates 502 needs to be adjusted, the motor A is rotated, and the motor A is used to drive the matching gear 106 to rotate, so that the matching gear 106 drives the matching gear ring 105 to rotate, and then the ring 201 is rotated to complete the subsequent rotation effect of the multiple extension plates 502.
