Description

Technical Field

[0001] This invention relates to the field of rice harvesting technology, and in particular to a vibrating conveyor for a rice harvester. Background Technology

[0002] A rice harvester is an agricultural machine specifically designed for harvesting rice. It can efficiently complete harvesting, threshing, and cleaning operations, significantly improving rice harvesting efficiency and reducing manual labor intensity. During the harvesting stage, the rice plants are cut by the header (equipped with a cutter or reel), and the divider guides the rice clumps into the harvester to prevent lodged rice from being missed. The cut rice is then transported to the threshing unit via a feed conveyor belt. While the rice is being harvested, weeds are also being harvested simultaneously. At this time, the seeds of these weeds (barnyard grass, barnyard grass) will follow into the threshing unit, resulting in a large number of weed seeds in the harvested rice, which will affect the subsequent rice processing. Furthermore, harvesters with screening functions will sieve the weed seeds and discharge them back into the field. Without processing the weed seeds, a large number of weeds will grow in the rice fields the following year, affecting rice planting and yield. Based on this, a vibrating conveyor device for a rice harvester is proposed. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that in the prior art, when weeds (barnyard grass) are harvested, their seeds are carried into the threshing device, resulting in a large number of weed seeds in the harvested rice, which affects the subsequent rice processing. Furthermore, harvesters with screening functions will screen the weed seeds and discharge them back into the field. Without treating the weed seeds, a large number of weeds will grow in the rice field the following year, affecting rice planting and yield. Therefore, a vibrating conveyor device for rice harvesters is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vibrating conveyor for a rice harvester includes a weed treatment mechanism and a cutting mechanism installed between two sets of feed conveyor belts of the rice harvester. The weed treatment mechanism includes a grass seed collection cylinder installed on the harvester frame. A vertical drive motor is installed inside the grass seed collection cylinder. The output end of the vertical drive motor is connected to a drive vertical shaft. The drive vertical shaft is connected to a pressing collection plate through multiple brackets. A serrated scraping plate is installed above the pressing collection plate. The serrated scraping plate is composed of multiple serrated combination plates. The serrated combination plates are connected to the drive vertical shaft through a traction connector. A support sleeve is fixedly installed on the grass seed collection cylinder and sleeved on the drive vertical shaft. A scraping and collecting device is installed on the side wall of the support sleeve located at the pressing collection plate. A magnetic repulsion component for controlling the upward movement of the serrated combination plates is installed on the top of the support sleeve.

[0006] The cutting mechanism includes a support end plate mounted on the harvester frame, a transverse bearing plate fixedly connected to the support end plate, and cutting discs for cutting weeds provided at both ends of the transverse bearing plate. A drive assembly for driving the cutting discs to rotate is provided on the support end plate.

[0007] As a preferred embodiment, the traction connector includes a suspension disc fixedly connected to the outer wall of the drive vertical shaft, an inner ring body fixedly connected to the inner wall of the serrated combination disc, the inner wall of the inner ring body being connected to the outer wall of the drive vertical shaft through a flexible connecting layer, and a telescopic folding rod connected to the upper surface of the inner ring body through a spherical connector, the top of the telescopic folding rod being rotatably connected to the suspension disc through a rotating shaft.

[0008] As a preferred embodiment, a traction turntable is fixedly connected to the outer wall of the drive vertical shaft, and the traction turntable is connected to the inner wall of the sawtooth combination disc through a traction hook spring.

[0009] As a preferred embodiment, the scraping and collecting device includes a connecting shaft rotatably mounted on the side wall of the support sleeve. One end of the connecting shaft is fixedly connected to a helical gear, and the other end is fixedly connected to a scraping cylinder. The outer wall of the scraping cylinder is provided with a scraping blade, and the outer wall of the driving vertical shaft is fixedly connected to a helical gear disk that meshes with multiple helical gears.

[0010] As a preferred embodiment, the magnetic repulsion assembly includes a sector-shaped magnetic repulsion base fixedly connected to the top of the support sleeve, and a fixed magnetic repulsion ring fixedly connected to the inner side wall of the sawtooth combination disk, wherein the fixed magnetic repulsion ring and the sector-shaped magnetic repulsion base are magnetically repelled.

[0011] As a preferred embodiment, a cutting shaft is fixedly connected to one end of the cutting disc. The cutting shaft at one end extends outward through the transverse support plate, and the cutting shaft at the other end is connected to the transverse support plate through a rotatably connected support transverse shaft.

[0012] As a preferred embodiment, the drive assembly includes a dual drive motor mounted on a support end plate, with drive worm gears fixedly connected to both ends of the dual drive motors, and a worm gear disk meshing with the drive worm gears fixedly connected to the outer side wall of the end of the cutting shaft.

[0013] As a preferred embodiment, the bottom of the sawtooth combination disc is provided with a sawtooth blade, and the upper surface of the pressing collection disc is provided with a wear-resistant fiber layer.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention uses the cooperation of a serrated scraping disc and a downward collecting disc to precisely bite and separate the weed seed parts, avoiding the problem of weed seeds being mixed into rice or returned to the field during traditional harvesting. The scraping cylinder uses a rotating scraping blade to collect the weed seeds into a detachable weed seed collecting cylinder, realizing automated collection. The weed seeds are collected in a centralized manner through the weed seed collecting cylinder, avoiding the weed seeds being discharged back into the field after sieving, significantly reducing the risk of weed growth in the field the following year, and ensuring a clean rice planting environment.

[0016] 2. This invention employs a control method combining a "magnetic repulsion assembly (fan-shaped magnetic repulsion base and fixed magnetic repulsion ring)" and a "traction hook spring." At a specific location (when encountering grass seeds), the device uses magnetic repulsion to move the sawtooth assembly disk upwards, "opening" it. After the grass seeds enter, the spring pull automatically presses down, "engaging" them. This achieves automatic capture and fixation of the grass seeds in motion. An independent cutting mechanism cuts the engaged grass seeds from the weeds. Simultaneously, a rotating scraping cylinder, driven synchronously by a vertical shaft, continuously scrapes the trapped grass seeds into a collection cylinder, achieving automatic cleaning of the collection surface, preventing blockages, and ensuring continuous operation.

[0017] 3. The cutting mechanism designed in this invention uses a dual-drive motor to drive the cutting disc, which quickly cuts the connection between the roots and seeds of weeds, enabling simultaneous harvesting, threshing, and seed processing, reducing process interruptions. Furthermore, the designed vibrating conveyor is integrated between the feed conveyor belts, requiring no major modifications to the harvester structure and making it easy to promote and use.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Example, refer to Figures 1 to 6A vibrating conveying device for a rice harvester includes a weed handling mechanism and a cutting mechanism installed between two sets of feeding conveyor belts of the rice harvester. Under the action of the harvester's header, the rice and weeds are cut together, and the rice is divided into clusters and introduced into the harvester through a divider. Under the action of the feeding conveyor belt, the rice and weeds are conveyed forward together. The weed handling mechanism includes a grass seed collection cylinder 1 installed on the harvester frame. The grass seed collection cylinder 1 can be detachable or externally connected to a discharge pipe. A vertical drive motor 2 is installed inside the grass seed collection cylinder 1. The output end of the vertical drive motor 2 is connected to a drive vertical shaft 24. The drive vertical shaft 24 is connected to a downward collection plate 3 through multiple brackets. The upper surface of the downward collection plate 3 is provided with a wear-resistant fiber layer 23, and a serrated scraping disc is provided above the downward collection plate 3.

[0029] The serrated scraping disc is composed of multiple serrated combination discs 4. The bottom of the serrated combination disc 4 is provided with serrated blades, which can bite the roots and stems of weeds. The serrated combination disc 4 is connected to the drive vertical shaft 24 through a traction connector. Further, the traction connector includes a suspension disc 9 fixedly connected to the outer wall of the drive vertical shaft 24. An inner ring body 10 is fixedly connected to the inner wall of the serrated combination disc 4. The inner wall of the inner ring body 10 is connected to the outer wall of the drive vertical shaft 24 through a flexible connecting layer 11. A telescopic folding rod 13 is connected to the upper surface of the inner ring body 10 through a ball connector 12. The top of the telescopic folding rod 13 is rotatably connected to the suspension disc 9 through a rotating shaft.

[0030] It should be noted that the magnetic repulsion component causes the sawtooth combination disk 4 to move up and down. The telescopic folding rod 13 ensures effective support and combination connection of the sawtooth combination disk 4.

[0031] A traction turntable 25 is fixedly connected to the outer wall of the drive vertical shaft 24. The traction turntable 25 is connected to the inner wall of the sawtooth combination plate 4 through the traction hook spring 26. The traction hook spring 26 exerts a downward traction force on the sawtooth combination plate 4 at all times.

[0032] The advantage of the above structure is that the seed part of the weed will be located at one end of the feeding conveyor belt. When it touches the pressure collection plate 3 during the conveying process, the saw tooth combination plate 4 driven by the vertical drive motor 2 is in an upward opening state under the action of the fixed magnetic repulsion ring 18 and the fan-shaped magnetic repulsion seat 17. The seed part of the weed is exactly in the middle of the pressure collection plate 3 and the saw tooth combination plate 4, and will be bitten by the saw tooth combination plate 4 during the conveying process.

[0033] A support sleeve 5 is fixedly installed on the grass seed collection cylinder 1 and sleeved on the drive vertical shaft 24. A scraping collection device is provided on the side wall of the support sleeve 5 located at the lower collection plate 3. Further, the scraping collection device includes a connecting shaft 15 rotatably installed on the side wall of the support sleeve 5. One end of the connecting shaft 15 is fixedly connected to a helical gear, and the other end is fixedly connected to a scraping cylinder 14. A scraping blade is provided on the outer wall of the scraping cylinder 14. A helical gear disk 16 that meshes with multiple helical gears is fixedly connected to the outer wall of the drive vertical shaft 24. It can drive multiple helical gears to rotate at the same time. The rotation of the scraping cylinder 14 can scrape grass seeds into the grass seed collection cylinder 1 below.

[0034] The top of the support sleeve 5 is provided with a magnetic repulsion component for controlling the upward movement of the sawtooth combination disk 4. The magnetic repulsion component includes a sector-shaped magnetic repulsion seat 17 fixedly connected to the top of the support sleeve 5. A fixed magnetic repulsion ring 18 is fixedly connected to the inner wall of the sawtooth combination disk 4. The fixed magnetic repulsion ring 18 and the sector-shaped magnetic repulsion seat 17 are magnetically repelled. Under the action of the fixed magnetic repulsion ring 18 and the sector-shaped magnetic repulsion seat 17, the sawtooth combination disk 4 is in an upward opening state. In other positions, the sawtooth combination disk 4 is in a downward engaging state.

[0035] The cutting mechanism includes a support end plate 6 installed on the harvester frame, a transverse bearing plate 7 fixedly connected to the support end plate 6, and a cutting disc 8 for cutting weeds at both ends of the transverse bearing plate 7. A drive assembly for driving the cutting disc 8 to rotate is provided on the support end plate 6.

[0036] Furthermore, a cutting shaft 19 is fixedly connected to one end of the cutting disc 8. The cutting shaft 19 at one end extends outward through the transverse support plate 7, and the cutting shaft 19 at the other end is connected to the transverse support plate 7 through a rotatably connected support transverse shaft 20. The drive assembly includes a dual drive motor 21 set on the support end plate 6. Both ends of the dual drive motor 21 are fixedly connected to drive worm gears, and a worm gear disk 22 that meshes with the drive worm gear is fixedly connected to the outer wall of the end of the cutting shaft 19.

[0037] In use, this invention cuts rice and weeds together under the action of the harvester's header. The rice is then divided into clumps and fed into the harvester by a divider. The rice and weeds are then conveyed forward together by the feed conveyor belt. Since the weeds are taller than the rice, their roots, stems, and leaves are at the feed conveyor belt, while the harvested seeds are located at both ends of the belt (the width of the feed conveyor belt is designed to be exactly the same as the length of the cut rice). The weed seeds are located at one end of the feed conveyor belt. When they touch the lower collection plate 3 during transport, they are activated by the vertical drive motor. The sawtooth combination disc 4 driven by the machine 2 is in an upward opening state under the action of the fixed magnetic repulsion ring 18 and the fan-shaped magnetic repulsion seat 17. The weed seed part is exactly in the middle of the downward collection disc 3 and the sawtooth combination disc 4. When the fixed magnetic repulsion ring 18 on the sawtooth combination disc 4 moves away from the fan-shaped magnetic repulsion seat 17, it will automatically press down under the action of the traction hook spring 26. During the downward movement, the sawtooth combination disc 4 with sawtooth blades bites the weed seed part between the sawtooth combination disc 4 and the downward collection disc 3. During the forward conveying process, the cutting disc 8 cuts the weeds from the middle part and the weed seed part.

[0038] The roots and stems of weeds are processed along with the rice harvester, while weed seeds enter the pressing collection disc 3. Under the action of the continuously rotating scraping cylinder 14, they are collected into the seed collection cylinder 1 below, achieving centralized collection. This facilitates the centralized destruction of weed seeds and effectively prevents them from being released back into the field, thus avoiding impacting the planting and yield of the next season's rice. This measure cuts off the natural dispersal cycle of weeds in the field through seeds, effectively reducing the amount of weeds in the field the following year, lowering the amount of herbicides used and the cost of manual weeding, which is conducive to protecting the farmland ecological environment and achieving sustainable and high-yield rice cultivation.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
