Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural power machinery technology, and in particular to an intelligent harvester with a modular design. Background Technology

[0002] Intelligent agricultural power machinery refers to a general term for agricultural operation equipment that integrates core technologies such as intelligent control and sensing, can realize automated and precise operation of agricultural production operations, can adapt to the needs of different field scenarios, and help improve production efficiency.

[0003] Harvesters are a widely used and typical category of intelligent agricultural power machinery systems. Their core advantage stems from the integrated design of the entire crop harvesting process. This breaks the fragmented process of traditional manual harvesting or decentralized mechanical operations. By integrating and linking key operational links such as harvesting, conveying, and preliminary processing, the problem of disconnect between different processes is avoided. This fundamentally reduces the time loss and connection costs during process switching, thereby promoting a systematic improvement in agricultural production efficiency.

[0004] In related technologies, such as Chinese patent CN114175913B, a combine harvester is disclosed, which includes a threshing header device, a lifting bridge device, a threshing and separating device, a cleaning device, a stalk diameter chopping device, a grain collecting device, a grain gathering device, and a drive device. The threshing header device includes a threshing reel and a header mechanism, which is located between the threshing reel and the lifting bridge device to receive the straw cut by the header mechanism and transport the straw to the threshing and separating device.

[0005] However, when the above-mentioned combine harvesters are actually used in the field, the fixed angle of the reel teeth cannot adapt to the differences in crop growth characteristics, which affects the efficiency of operation. At the same time, the rigid teeth are prone to causing large grain loss when in contact with crops, which affects the harvest. While the elastic teeth can reduce grain loss, frequent deformation leads to a shorter service life and requires frequent replacement. Summary of the Invention

[0006] Therefore, it is necessary to provide a modularly designed intelligent harvester to address the problems of low operating efficiency and poor reliability of the pick teeth in current harvesters.

[0007] The above objectives are achieved through the following technical solutions: A modularly designed intelligent harvester includes a harvester body with a header. A reel is installed within the header, comprising two central spokes arranged opposite each other and capable of rotating synchronously around their own axes. Multiple support rods are circumferentially arranged between the two central spokes, each capable of rotating synchronously with and relative to the central spokes around its own axis. Each support rod has multiple teeth, spaced apart along its extension direction and all being rigid structures. An eccentric spoke is rotatably mounted on the outer side of each central spoke, and multiple connecting rods are rotatably mounted on each eccentric spoke, arranged circumferentially. A central rod is fixedly sleeved onto each connecting rod. The components are rotatably mounted on the support rods; a first gear is rotatably mounted in the middle of each intermediate rod; each first gear has a first arc groove and a second arc groove, the support rod is slidably inserted into the first arc groove, and the connecting rod is slidably inserted into the second arc groove; a second gear is fixedly mounted on each first gear; a third gear is fixedly mounted on each support rod, and the third gear meshes with the second gear; an adjusting disc is eccentrically mounted between each central disc and an eccentric disc, the adjusting disc can rotate around its own axis, and is connected to the cutting table through a locking element, the locking element being used to lock the adjusting disc on the cutting table; each adjusting disc has multiple arc-shaped racks, the multiple arc-shaped racks are arranged circumferentially, and each meshes with a first gear, the arc-shaped racks can elastically slide along the circumference of the adjusting disc.

[0008] Furthermore, the locking element is a fixing pin, which is detachably connected between the adjusting plate and the cutting table.

[0009] Furthermore, a first elastic ring is inserted into the first arc groove. The first elastic ring has a wave structure, and the support rod is movably inserted into the first elastic ring.

[0010] Furthermore, the first elastic ring and the first gear are connected in a detachable manner.

[0011] Furthermore, a second elastic ring is inserted into the second arc groove. The second elastic ring has a wave structure, and the connecting rod is movably inserted into the second elastic ring.

[0012] Furthermore, the second elastic ring and the first gear are connected in a detachable manner.

[0013] Furthermore, each arc-shaped rack is connected to the first gear via two elastic elements.

[0014] Furthermore, a feeding auger is installed inside the header. The feeding auger is located behind the reel and can rotate around its own axis. The modularly designed smart harvester also includes a drive assembly, which is configured to provide the driving force for the rotation of the feeding auger.

[0015] Furthermore, the drive assembly includes a drive motor mounted on the cutting table; a first transmission wheel is fixedly sleeved on the motor shaft of the drive motor; a second transmission wheel is fixedly sleeved on the feeding auger; and a first transmission component is connected between the first transmission wheel and the second transmission wheel.

[0017] The beneficial effects of this invention are: This invention relates to a modularly designed intelligent harvester. By setting up a first gear, a second gear, a third gear, an adjusting disc, a locking component, and an arc-shaped rack, and utilizing the transmission relationship between these structures, the orientation of the pick teeth can be adjusted according to the differences in crop growth characteristics, thereby improving applicability. At the same time, by setting the pick teeth as a rigid structure and utilizing the characteristic that the arc-shaped rack can elastically slide along the circumference of the adjusting disc, elastic buffering of the rigid pick teeth can be achieved, which helps to improve the reliability of the pick teeth in use.

[0018] Furthermore, by setting a first elastic ring, when the support rod slides along the first arc groove, the elastic deformation of the first elastic ring is used to strengthen the elastic buffering of the rigid teeth, thereby further improving the reliability of the teeth.

[0019] Furthermore, by setting the first elastic ring and the first gear to be detachably connected, the first elastic ring can be easily replaced.

[0020] Furthermore, by setting a second elastic ring, when the connecting rod slides along the second arc groove, the elastic deformation of the second elastic ring is used to strengthen the elastic buffering of the rigid shift teeth, thereby further improving the reliability of the shift teeth.

[0021] Furthermore, by setting the second elastic ring and the first gear to be detachably connected, the second elastic ring can be easily replaced. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] The following reference Figures 1 to 10 This invention describes a modularly designed intelligent harvester, which is particularly suitable for harvesting crops.

[0028] Specifically, the modularly designed intelligent harvester includes a harvester body 1, a header 2 on the front side of the harvester body 1, and a bucket-shaped structure with open top and front side walls. Inside the header 2 are a cutter 3, a reel 4, and a feeding auger 5. The cutter 3 is located at the bottom of the header 2 and is configured to cut crops from the root. It can be configured to include multiple blades 301, which are arranged horizontally in the left-right direction. The multiple blades 301 are arranged in pairs, and the two blades 301 in the same pair can move synchronously in a direction that approaches or moves away from each other to cut the root of the crop. The feeding auger 5 is located behind the cutter 3 and extends horizontally in the left-right direction. It can rotate around its own axis and is configured to transport the cut crops into the harvester body 1.

[0029] To facilitate the driving force for the rotation of the feeding auger 5, the modularly designed intelligent harvester also includes a drive assembly 6, which includes a drive motor 601 mounted on the header 2. A first transmission wheel 602 is fixedly sleeved on the motor shaft of the drive motor 601. A second transmission wheel 603 is fixedly sleeved on the feeding auger 5. A first transmission component is connected between the first transmission wheel 602 and the second transmission wheel 603. When both the first transmission wheel 602 and the second transmission wheel 603 are pulleys, the first transmission component is a first transmission belt 604. When both the first transmission wheel 602 and the second transmission wheel 603 are sprockets, the first transmission component is a first transmission chain.

[0030] The reel 4 is located above the cutter 3 and includes a reel shaft 401. The reel shaft 401 is horizontally positioned and extends in the left-right direction, and can rotate around its own axis. Both ends of the reel shaft 401 are fixedly sleeved with central spokes 402. Under the constraint of the reel shaft 401, the two central spokes 402 are arranged horizontally at intervals in the left-right direction and are positioned opposite each other. They can synchronously follow the reel shaft 401 to rotate around its own axis. The shape of the central spokes 402 is an N-pointed star, and the center coincides with the axis of the reel shaft 401. Taking N equal to five as an example, the shape of the central spokes 402 is a pentagram.

[0031] To facilitate the provision of driving force for the rotation of the central spoke 402, a third transmission wheel 7 is fixedly sleeved on the reel shaft 401; a second transmission component is connected between the second transmission wheel 603 and the third transmission wheel 7. When the second transmission wheel 603 is a pulley, the third transmission wheel 7 is a pulley, and the second transmission component is a second transmission belt 8; when the second transmission wheel 603 is a sprocket, the third transmission wheel 7 is a sprocket, and the second transmission component is a second transmission chain.

[0032] Multiple support rods 403 are arranged circumferentially between the two central spokes 402. The support rods 403 are parallel to the reel shaft 401. When the shape of the central spoke 402 is a pentagram, there are five support rods 403, which are located at the five corners of the central spoke 402 and pass through the two central spokes 402 at both ends. This allows the support rods 403 to rotate synchronously with the central spoke 402 and rotate relative to the central spoke 402 around their own axis. Each support rod 403 has multiple teeth 404 at its bottom. The teeth 404 on the same support rod 403 are arranged at equal intervals along the extension direction of the support rod 403. The teeth 404 are L-shaped rod structures with an obtuse angle between the two rod-shaped parts of the teeth 404 and are set backward. The teeth 404 are rigid structures.

[0033] Each central disc 402 has an eccentric disc 405 eccentrically mounted on its outer side. The two eccentric discs 405 are arranged horizontally at intervals in the left-right direction and can rotate around their own axis. The base shape of the eccentric disc 405 is N-shaped. Taking N equals five as an example, the base shape of the eccentric disc 405 is a pentagram, and the outer periphery is provided with a regular pentagonal frame. Each eccentric disc 405 has multiple connecting rods 406 rotatably mounted on it. The connecting rods 406 and the support rods 403 are arranged in parallel. When the base shape of the eccentric disc 405 is a pentagram, there are five connecting rods 406, and the five connecting rods 406 are located at the five corners of the eccentric disc 405, arranged circumferentially. The inner end of each connecting rod 406 is fixedly sleeved with an intermediate rod 407. The intermediate rod 407 and the connecting rod 406 are arranged perpendicularly and are simultaneously fixedly sleeved on the support rod 403.

[0034] Taking the first transmission component as the first transmission belt 604 and the second transmission component as the second transmission belt 8 as an example. During operation, the drive motor 601 is first started, which drives the first transmission wheel 602 to rotate. When the first transmission wheel 602 rotates, it synchronously drives the second transmission wheel 603 to rotate via the first transmission belt 604. When the second transmission wheel 603 rotates, it synchronously drives the feeding auger 5 to rotate and, on the other hand, it synchronously drives the third transmission wheel 7 to rotate via the second transmission belt 8. When the third transmission wheel 7 rotates, it synchronously drives the central spoke 402 to rotate via the reel shaft 401. When the central spoke 402 rotates, it synchronously drives the support rod 403 to revolve around the reel shaft 401. When the support rod 403 rotates, it synchronously drives the eccentric spoke 405 to rotate via the intermediate rod 407 and connecting rod 406, and, on the other hand, it synchronously drives the pick teeth 404 to revolve around the reel shaft 401. Under the action of the intermediate rod 407, connecting rod 406 and eccentric spoke 405, the pick teeth 404 always face one direction. At the same time, the cutter 3 is started.

[0035] Then, the harvester body 1 is set to move along a predetermined route in the field. The crops are first moved towards the header 2 by the toothed teeth 404, and then cut off from the root by the cutter 3. Then, as the toothed teeth 404 move to the feeding auger 5, the crops are transported into the harvester body 1 by the feeding auger 5 to achieve harvesting.

[0036] While the above process can harvest crops, for crops with tall stalks, heavy ears that droop easily, the fixed-angle teeth 404 may not be able to effectively lift the drooping ears, resulting in the ears being positioned too low during cutting, and some grains may be accidentally cut or missed in the field. For crops with short stalks and upright growth, the fixed-angle teeth 404 may be too high in contact with the crops, failing to fully adhere to the crop stalks, resulting in poor crop gathering and affecting the gripping and transfer efficiency of the feeding auger 5, thereby reducing the overall operating efficiency.

[0037] Meanwhile, to reduce grain loss caused by rigid collisions when the 404 pick teeth come into contact with crops, some designs use elastic materials for the 404 pick teeth. Elastic 404 pick teeth can deform to some extent when in contact with crops, buffering the impact and reducing the impact on the grains, thus reducing grain loss and ensuring a good harvest. However, the inherent characteristics of elastic materials mean they are prone to fatigue during frequent deformation. In field operations, the 404 pick teeth continuously contact a large amount of crops and repeatedly deform. After long-term operation, the molecular structure of the elastic material gradually deteriorates, leading to a decrease in the elastic recovery ability and strength of the 404 pick teeth, resulting in cracking, breakage, and other damage, significantly shortening their service life. This means that harvesters using flexible 404 teeth need to stop frequently to replace the 404 teeth, which not only increases equipment maintenance costs but also extends working time due to the increased number of downtimes, thus affecting overall work efficiency. If rigid 404 teeth are used in pursuit of a longer service life, the impact force cannot be buffered, resulting in a significant increase in grain loss, which is also difficult to balance the needs of work performance and equipment durability.

[0038] Based on this, in the modularly designed intelligent harvester provided in this embodiment of the invention, the support rod 403 and the intermediate rod 407 are rotatably connected; and a first gear 408 is rotatably provided on the inner side of the middle part of each intermediate rod 407, the axis of the first gear 408 extending horizontally in the left-right direction; a first arc groove 4081 is provided on the inner side wall of each first gear 408, the first arc groove 4081 and the first gear 408 are coaxially arranged, and a second arc groove 4082 is provided on the outer side wall of each first gear 408. The first gear 408 is coaxially arranged and opposite to the first arc groove 4081; the support rod 403 passes through the first sliding groove 4111 and is slidably inserted into the first arc groove 4081; the support rod 403 is slidably inserted into the second arc groove 4082; a second gear 409 is coaxially and fixedly arranged on the inner side wall of each first gear 408; a third gear 410 is fixedly sleeved on each support rod 403, the third gear 410 meshes with the second gear 409, and the third gear 410 is located between the first gear 408 and the central spoke 402.

[0039] An adjusting disc 411 is eccentrically positioned between each central disc 402 and eccentric disc 405. The two adjusting discs 411 are horizontally spaced in the left-right direction. Each adjusting disc 411 can rotate around its own axis and is connected to the cutting table 2 via a locking element. The locking element is used to lock the adjusting disc 411 onto the cutting table 2. The locking element can be a fixing pin 412, which extends horizontally in the left-right direction and is simultaneously inserted into both the cutting table 2 and the adjusting disc 411, facilitating the locking of the adjusting disc 411 onto the cutting table 2 and restricting its rotation. Five arc-shaped racks 413 are provided on the peripheral sidewall of each adjusting disc 411. The arc-shaped racks 413 are coaxially arranged with the adjusting disc 411, and are evenly distributed circumferentially, each meshing with a first gear 408. Five... Five slide grooves 4111 are evenly arranged circumferentially. The slide grooves 4111 are arc-shaped and coaxially arranged with the adjusting disk 411. The cross-sectional shape of the slide grooves 4111 can be set as an inverted T-shape. Each arc-shaped rack 413 has a slider 4131 on its inner sidewall. The cross-sectional shape of the slider 4131 can be set as an inverted T-shape and inserted into the slide groove 4111. Under the constraint of the T-shaped structure, the slider 4131 can slide along the slide groove 4111 without disengaging from the slide groove 4111. Two elastic elements are inserted in each slide groove 4111. The elastic elements can be springs 414. The springs 414 extend circumferentially along the adjusting disk 411 and are respectively connected between the slider 4131 and the end of the slide groove 4111. Under the action of the springs 414, the arc-shaped rack 413 can slide elastically along the circumferential direction of the adjusting disk 411.

[0040] Initially, the fixing pin 412 is inserted into both the cutting table 2 and the adjusting plate 411, at which time the adjusting plate 411 cannot rotate; the slider 4131 is located in the middle of the slide groove 4111.

[0041] During the adjustment of the orientation of the reel 404, the drive motor 601 is first started. The drive motor 601 drives the first transmission wheel 602 to rotate. When the first transmission wheel 602 rotates, it synchronously drives the second transmission wheel 603 to rotate via the first transmission belt 604. When the second transmission wheel 603 rotates, it synchronously drives the third transmission wheel 7 to rotate via the second transmission belt 8. When the third transmission wheel 7 rotates, it synchronously drives the central spoke 402 to rotate via the reel shaft 401. When the central spoke 402 rotates, it synchronously drives the support rod 403 to revolve around the reel shaft 401. When the support rod 403 rotates, it synchronously drives the first gear 408 to rotate around the reel shaft 401. Since the adjusting disc 411 is stationary, the first gear 404 rotates... 8. The synchronous engagement between the arc-shaped rack 413 and the adjusting disc 411 causes the arc-shaped rack 413 to slide relative to the adjusting disc 411 along the slide groove 4111, compressing one side of the spring 414 and stretching the other side. When the spring 414 reaches its limit, the arc-shaped rack 413 remains stationary. The first gear 408 rotates through meshing with the arc-shaped rack 413, driving the second gear 409 to rotate. The second gear 409, through meshing with the third gear 410, drives the support rod 403 to rotate. The support rod 403 drives the prying teeth 404 to rotate around the support rod 403, thus allowing the orientation of the prying teeth 404 to be adjusted according to the different growth characteristics of crops, improving applicability. When the first gear 408 rotates, the support rod 403 simultaneously slides along the first arc groove 4081, and the connecting rod 406 simultaneously slides along the second arc groove 4082, avoiding interference.

[0042] When the tooth 404 is facing the set direction, the drive motor 601 is turned off, and then the fixing pin 412 is pulled out. The compressed spring 414 and the stretched spring 414 are released, which drives the adjusting plate 411 to rotate until the slider 4131 is located in the middle of the slide groove 4111, thus achieving reset.

[0043] Then, the drive motor 601 is restarted, which drives the reel 4 and the feeding auger 5 to move, and simultaneously starts the cutter 3. Then, the harvester body 1 is set to move along a predetermined route in the field. When the crop comes into contact with the reel tooth 404, the reel tooth 404 drives the support rod 403 to rotate under the obstruction of the crop. The support rod 403 drives the third gear 410 to rotate. The third gear 410 drives the first gear 408 to rotate through the meshing between the third gear 410 and the second gear 409. The first gear 408 drives the slider 4131 to slide along the slide groove 4111 through the meshing between the first gear 408 and the arc rack 413. Simultaneously, one side of the spring 414 is compressed and the other side of the spring 414 is stretched, thereby achieving elastic buffering of the rigid reel tooth 404, reducing grain loss, and utilizing the rigidity of the reel tooth 404 to improve its service life, thereby improving the reliability of the reel tooth 404.

[0044] In a further embodiment, to further enhance the elastic buffering of the rigid pry bar 404, a first elastic ring 415 can be inserted into the first arc groove 4081. The first elastic ring 415 has a wave structure, and the support rod 403 is movably inserted into the first elastic ring 415.

[0045] Thus, during use, when crops come into contact with the prying teeth 404, the rotation of the first gear 408 will cause the support rod 403 to slide along the first arc groove 4081, and simultaneously cause the first elastic ring 415 to undergo elastic deformation, thereby further strengthening the elastic buffering of the rigid prying teeth 404.

[0046] In a further embodiment, to facilitate the replacement of the first elastic ring 415, the first elastic ring 415 and the first gear 408 are detachably connected by a pin.

[0047] In other embodiments, to further enhance the elastic buffering of the rigid pry bar 404, a second elastic ring 416 may be inserted into the second arc groove 4082. The second elastic ring 416 has a wave structure, and the connecting rod 406 is movably inserted into the second elastic ring 416.

[0048] Thus, during use, when the crop comes into contact with the prying tooth 404, the rotation of the first gear 408 will cause the connecting rod 406 to slide along the second arc groove 4082, and simultaneously cause the second elastic ring 416 to undergo elastic deformation, thereby further strengthening the elastic buffering of the rigid prying tooth 404.

[0049] In a further embodiment, to facilitate the replacement of the second elastic ring 416, the second elastic ring 416 and the first gear 408 are detachably connected by a pin.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
