A rice harvester capable of self-adapting cutting width

Abstract

This utility model provides a rice harvester with adaptively adjustable cutting width, belonging to the field of agricultural machinery. It includes a machine body, with an adjustment component fixedly installed on one side of the machine body. During use, the adjustment component allows for support from a support frame on one side of the machine body. A hydraulic rod on the support frame can raise and lower the material winding frame, adapting the adjustment device to the height of the rice. A first motor at the bottom of the lifting frames on both sides of the material winding frame drives a threaded rod to rotate, causing the lifting block to move up and down along the threaded rod, adjusting the height of the rotating column and the surrounding cutting buckets, thus controlling the cutting depth of the cutting blades. The rotating column can adjust the angle of the cutting buckets. Support plates on the fixed columns on both sides of the material winding frame, in conjunction with the adjustment rod, work together with the cutting buckets to flexibly adjust the cutting width. When the rice is densely planted, the cutting width is reduced to avoid straw clogging; when the planting is sparse, the cutting width is expanded, achieving adaptive adjustment of the cutting width.

Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and more specifically, to a rice harvester with an adaptively adjustable cutting width. Background Technology

[0002] The development of rice harvesters is closely linked to the process of agricultural mechanization. As early as the last century, rice harvesting in my country mainly relied on human and animal power, which was inefficient. With the development of the times, mechanized rice harvesters have emerged. From initially imitating foreign models to independent research and development, their performance has been continuously improved. Today, rice harvesters have functions such as automatic navigation and automatic crop identification, which greatly improves the efficiency of operation. However, in the complex and ever-changing rice planting environment, existing harvesters still have limitations in terms of cutting width adjustment, making it difficult to flexibly and accurately adapt and adjust according to the actual situation, which limits the further improvement of harvesting efficiency and quality.

[0003] A search revealed Chinese patent CN109089525A, which discloses "an automatic rice harvester, comprising a rice-picking device, a harvesting device, a chassis, a frame, a threshing device, a separating device, a unloading device, and a storage bin. The rice-picking device includes rice-picking rollers, two roller support arms, and a pressing belt. The harvesting device includes three cutters mounted at the front end of the chassis and a first drive device fixedly mounted on the top of the chassis. The threshing device includes a first roller, a second roller, and threshing plates in the shape of two adjacent arcs. The separating device includes a first separating screen, a second separating screen, a second drive device, and a swinging device. The unloading device includes a third drive device, a fourth drive device, and screen plates in the shape of two adjacent arcs. This automatic rice harvester can automatically complete the rice harvesting process, effectively improving production efficiency and reducing the loss rate after rice hulling, and is very convenient to operate." However, it still has the following drawbacks:

[0004] (1) In actual use, the device does not have a design to adjust the harvesting width. The rice planting row spacing varies in different fields. The fixed width cannot be adapted to planting scenarios with different widths. When encountering fields with narrow row spacing, it is easy to miss or repeat the harvesting. When facing fields with wide row spacing, the device performance cannot be fully utilized, resulting in a limited harvesting area per harvest, which increases the working time and fuel consumption.

[0005] (2) In actual use, the device lacks a rapid material winding and cutting design. Rice straw is soft and easily tangles together. The lack of a rapid material winding mechanism makes it impossible to efficiently gather the straw. The single cutting structure has low cutting efficiency. During the peak rice ripening period, it is difficult to quickly complete large-area harvesting and may miss the best harvesting time. Therefore, a rice harvester with adaptive adjustable cutting width is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in current devices that lack adjustable harvesting width, resulting in limited single-harvest area, increased operating time and fuel consumption. Furthermore, the lack of a rapid material winding and cutting mechanism prevents efficient straw gathering, hindering large-area harvesting and causing missed harvesting opportunities. This invention provides a rice harvester with adaptively adjustable cutting width to solve the problems mentioned in the background section.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a rice harvester with adaptive adjustable cutting width, comprising a machine body, an adjustment component for adjusting the cutting width fixedly installed on one side of the machine body, and a material winding component for winding the material fixedly installed on one side of the machine body;

[0009] The adjustment assembly includes a support frame fixedly installed on one side of the machine body. A hydraulic rod is fixedly installed on one side of the support frame. A coil frame is fixedly installed at the bottom of the hydraulic rod. Lifting frames are fixedly installed on both sides of the coil frame. A first motor is fixedly installed at the bottom of the lifting frame. A threaded rod is fixedly installed at the output end of the first motor. Lifting blocks are threadedly installed on the periphery of the threaded rod. A rotating column is rotatably installed between the two lifting blocks. A cutting bucket is fixedly installed on the periphery of the rotating column. A cutting blade is fixedly installed on one side of the cutting bucket. Fixed columns are fixedly installed on both sides of the coil frame. Support plates are fixedly installed on the periphery of the fixed columns. An adjustment rod is fixedly installed on one side of the support plate. An adjustment plate is fixedly installed on the side of the adjustment rod away from the support plate.

[0010] As a preferred technical solution of this utility model, the coil assembly includes a protective shell fixedly installed on one side of the coil frame, a second motor fixedly installed on one side of the protective shell, a coil column fixedly installed at the output end of the second motor, a plurality of coil sheets fixedly installed around the coil column, a coil plate fixedly installed between two coil sheets, and a plurality of coil hooks fixedly installed on one side of the coil plate.

[0011] As a preferred technical solution of this utility model, a waterproof frame is fixedly installed on the side of the machine body near the support frame, a waterproof plate is fixedly installed on the top of the waterproof frame, and several drainage plates are fixedly installed on the top of the waterproof plate.

[0012] As a preferred technical solution of this utility model, an adjusting pad is fixedly installed on the side of the adjusting plate away from the adjusting rod. The adjusting pad is made of rubber, and several weft grooves are fixedly installed on the side of the adjusting pad away from the adjusting plate.

[0013] As a preferred technical solution of this utility model, a plurality of grass cutting boards are fixedly installed on the periphery of the roll column, and a grass cutting blade is fixedly installed between two of the grass cutting boards.

[0014] As a preferred embodiment of this invention, two lights are fixedly installed on one side of the support frame, and a warning light is fixedly installed on the side of the machine body away from the support frame.

[0015] As a preferred technical solution of this utility model, a plurality of partition plates are fixedly installed on the top of the cutting bucket, and a side blade is fixedly installed on the top of the partition plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Through the set adjustment components, during use, the support frame on one side of the machine body provides stable support for the adjustment structure. The hydraulic rod on the support frame can drive the entire winding frame to rise and fall, initially adjusting the height compatibility between the cutting device and the rice plants. The first motor at the bottom of the lifting frame on both sides of the winding frame drives the threaded rod to rotate, causing the lifting block to move up and down along the threaded rod, thereby adjusting the height of the rotating column and the surrounding cutting bucket, and precisely controlling the cutting depth of the cutting blade. At the same time, the rotating column can drive the cutting bucket to rotate and finely adjust the angle, ensuring that the cutting blade maintains the optimal cutting angle with the rice straw. In addition, the support plate on the fixed column on both sides of the winding frame, together with the adjustment rod, can push the adjustment plate to move laterally. The adjustment plate and the cutting bucket work together to flexibly adjust the cutting width by changing the extension length of the adjustment plate. When the rice is densely planted, the cutting width is narrowed to avoid straw congestion; when the planting is sparse, the cutting width is widened to improve harvesting efficiency, realizing adaptive adjustment of the cutting width.

[0018] 2. With the set-up material winding assembly, during use, the second motor inside the protective shell on one side of the material winding frame drives the material winding column to rotate, and the surrounding material winding sheets rotate synchronously with the material winding column, gathering the rice straw cut by the cutting blades towards the center; the material winding plates between the material winding sheets and the surrounding material winding hooks further enhance the winding capacity, firmly hooking the straw and conveying it upwards, preventing the straw from falling or piling up in the cutting area, ensuring that the cut straw can quickly enter the subsequent processing stage, reducing material loss in the harvesting process, and improving the overall harvesting efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 and Figure 2As shown, this embodiment proposes a rice harvester with adaptive adjustable cutting width, including a machine body 1, an adjustment component 2 for adjusting the cutting width is fixedly installed on one side of the machine body 1, and a material winding component 3 for winding material is fixedly installed on one side of the machine body 1.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment assembly 2 includes a support frame 201 fixedly installed on one side of the machine body 1. A hydraulic rod 202 is fixedly installed on one side of the support frame 201. A coil rack 203 is fixedly installed at the bottom of the hydraulic rod 202. Lifting frames 204 are fixedly installed on both sides of the coil rack 203. A first motor 205 is fixedly installed at the bottom of the lifting frame 204. A threaded rod 206 is fixedly installed at the output end of the first motor 205. Lifting blocks 207 are threadedly installed on the periphery of the threaded rod 206. Between the two lifting blocks 207... A rotating column 208 is rotatably mounted, and a cutting bucket 209 is fixedly mounted around the rotating column 208. A cutting blade 210 is fixedly mounted on one side of the cutting bucket 209. Fixed columns 211 are fixedly mounted on both sides of the coil rack 203, and support plates 212 are fixedly mounted around the fixed columns 211. An adjusting rod 213 is fixedly mounted on one side of the support plate 212, and an adjusting plate 214 is fixedly mounted on the side of the adjusting rod 213 away from the support plate 212. In use, the support frame 201 on one side of the machine body 1 is an adjustable structure. Providing stable support, the hydraulic rod 202 on the support frame 201 can drive the entire coil frame 203 to rise and fall, initially adjusting the height compatibility between the cutting device and the rice plant. The first motor 205 at the bottom of the lifting frames 204 on both sides of the coil frame 203 drives the threaded rod 206 to rotate, causing the lifting block 207 to move up and down along the threaded rod 206, thereby adjusting the height of the rotating column 208 and the surrounding cutting bucket 209, and precisely controlling the cutting depth of the cutting blade 210; at the same time, the rotating column 208 can drive the cutting bucket 209 to rotate. The angle is finely adjusted to ensure that the cutting blade 210 maintains the optimal cutting angle with the rice straw. In addition, the support plate 212 on the fixed columns 211 on both sides of the roll frame 203, together with the adjusting rod 213, can push the adjusting plate 214 to move laterally. The adjusting plate 214 works in conjunction with the cutting bucket 209 to flexibly adjust the cutting width by changing the extension length of the adjusting plate 214. When the rice is densely planted, the cutting width is narrowed to avoid straw congestion; when the planting is sparse, the cutting width is widened to improve harvesting efficiency, thus achieving adaptive adjustment of the cutting width.

[0031] like Figure 3 and Figure 5As shown, the coil assembly 3 includes a protective shell 301 fixedly installed on one side of the coil rack 203. A second motor 302 is fixedly installed on one side of the protective shell 301. A coil post 303 is fixedly installed at the output end of the second motor 302. Several coil sheets 304 are fixedly installed around the coil post 303. A coil plate 305 is fixedly installed between two coil sheets 304. Several coil hooks 306 are fixedly installed on one side of the coil plate 305. In use, the coil hooks inside the protective shell 301 on one side of the coil rack 203 are... The second motor 302 drives the winding column 303 to rotate, and the surrounding winding sheets 304 rotate synchronously with the winding column 303, gathering the rice straw cut by the cutting blade 210 towards the center; the winding plates 305 between the winding sheets 304 and the surrounding winding hooks 306 further enhance the winding capacity, firmly hooking the straw and conveying it upward, preventing the straw from falling or piling up in the cutting area, ensuring that the cut straw can quickly enter the subsequent processing stage, reducing material loss in the harvesting process, and improving the overall harvesting efficiency.

[0032] like Figure 3 and Figure 4 As shown, a waterproof frame 4 is fixedly installed on the side of the machine body 1 near the support frame 201. A waterproof plate 5 is fixedly installed on the top of the waterproof frame 4. Several drainage plates 6 are fixedly installed on the top of the waterproof plate 5. In use, the waterproof frame 4 on the side of the machine body 1 near the support frame 201 supports the waterproof plate 5, which can block rainwater and dew in rainy days or environments with heavy dew, preventing rainwater from seeping into the motor and transmission structure, and preventing parts from rusting or short-circuiting. The drainage plates 6 on the top of the waterproof plate 5 can quickly drain accumulated water, reduce the retention of rainwater on the surface of the waterproof plate 5, further improve the waterproof effect, and ensure the stable operation of the harvester in humid environments.

[0033] like Figure 4 As shown, an adjusting pad 7 is fixedly installed on the side of the adjusting plate 214 away from the adjusting rod 213. The adjusting pad 7 is made of rubber. Several dividing grooves 8 are fixedly installed on the side of the adjusting pad 7 away from the adjusting plate 214. When in use, the rubber adjusting pad 7 on the side of the adjusting plate 214 away from the adjusting rod 213 can play a buffering role when in contact with rice straw, avoiding rigid collision damage to the straw or the adjusting plate 214. The dividing grooves 8 on the periphery of the adjusting pad 7 can evenly separate the dense rice straw, preventing the straw from getting tangled on the adjusting plate 214. At the same time, it helps to adjust the direction of the straw, ensuring that the straw can accurately enter the cutting range of the cutting bucket 209, improving the accuracy of the cutting width adjustment and the harvesting quality.

[0034] like Figure 4As shown, several cutting boards 9 are fixedly installed around the periphery of the rolling column 303, and a cutting blade 10 is fixedly installed between two cutting boards 9. When in use, the cutting boards 9 around the rolling column 303 rotate with the rolling column 303 and cooperate with the cutting blade 10 between the cutting boards 9 to perform preliminary shredding of rice straw during the rolling process, shortening the subsequent straw crushing or recycling process; the cutting blade 10 can cut longer straw into smaller segments, which is convenient for subsequent transportation and can also reduce the straw volume, saving storage or transportation space.

[0035] like Figure 2 and Figure 4 As shown, two lights 11 are fixedly installed on one side of the support frame 201, and a warning light 12 is fixedly installed on the side of the machine body 1 away from the support frame 201. When in use, the two lights 11 on one side of the support frame 201 will light up in the early morning, evening or cloudy weather when the light is insufficient, providing sufficient lighting for the cutting area, making it convenient for operators to observe the growth status of rice and the cutting position, and avoiding cutting deviation due to poor visibility; the warning light 12 on the other side of the machine body 1 will flash when the harvester is in operation, reminding the surrounding personnel to pay attention to the position of the equipment, preventing collision accidents and improving the safety of operation.

[0036] like Figure 3 As shown, several partition plates 13 are fixedly installed on the top of the cutting hopper 209, and side blades 14 are fixedly installed on the top of the partition plates 13. In use, the partition plates 13 on the top of the cutting hopper 209 can separate the rice straw entering the cutting hopper 209 at certain intervals to prevent the straw from tangling together in the cutting hopper 209 and ensure that each straw can be cut evenly by the cutting blades 210. The side blades 14 on the top of the partition plates 13 can assist in cutting the straw near the edge of the cutting hopper 209 that are difficult for the cutting blades 210 to reach, reducing missed cutting and improving the integrity of harvesting.

[0037] Specifically, when using this adaptively adjustable rice harvester: the support frame 201 on one side of the machine body 1 provides stable support for the adjustment structure. The hydraulic rod 202 on the support frame 201 can drive the entire winding frame 203 to rise and fall, initially adjusting the height compatibility between the cutting device and the rice plant. The first motor 205 at the bottom of the lifting frames 204 on both sides of the winding frame 203 drives the threaded rod 206 to rotate, causing the lifting block 207 to move up and down along the threaded rod 206, thereby adjusting the height of the rotating column 208 and the surrounding cutting bucket 209, and precisely controlling the cutting depth of the cutting blade 210. Simultaneously, the rotating column 208 can drive the cutting bucket 209 to rotate and finely adjust the angle, ensuring that the cutting blade 210 maintains the optimal cutting angle with the rice straw. Furthermore, the support plates 212 on the fixed columns 211 on both sides of the roll frame 203, in conjunction with the adjusting rod 213, can push the adjusting plate 214 to move laterally. The adjusting plate 214 and the cutting bucket 209 work together to flexibly adjust the cutting width by changing the extension length of the adjusting plate 214. When rice is densely planted, the cutting width is reduced to avoid straw congestion; when planting is sparse, the cutting width is expanded to improve harvesting efficiency, achieving adaptive adjustment of the cutting width (e.g., ...). Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown), the second motor 302 inside the protective shell 301 on one side of the coiling frame 203 drives the coiling column 303 to rotate. The coiling sheets 304 on the periphery rotate synchronously with the coiling column 303, gathering the rice straw cut by the cutting blade 210 towards the center. The coiling plates 305 between the coiling sheets 304 and the coiling hooks 306 on the periphery further enhance the coiling capacity, firmly hooking the straw and conveying it upwards, preventing the straw from falling or accumulating in the cutting area, ensuring that the cut straw can quickly enter the subsequent processing stage, reducing material loss in the harvesting process, and improving the overall harvesting efficiency (such as...). Figure 3 and Figure 5 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
