Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a lateral conveying device and harvester for harvesting reed crops. Background Technology

[0002] Reeds are a tall crop that grows in wetlands and have significant ecological, economic, and cultural value. However, due to their harsh growing environment, manual harvesting is not only labor-intensive but also inefficient.

[0003] Many existing harvesting equipment are modified from harvesters used for low-stalk crops such as wheat and rice. Most are only capable of cutting and bundling reeds, requiring manual collection and bundling after the harvester cuts the roots. This makes them unsuitable for reeds with thicker and longer stalks, leading to high machine failure rates and significant reed harvesting losses. Currently, most reed harvesting equipment in China uses single-layer cutting and conveying devices. However, reed stalks are relatively tall, and single-layer conveying devices easily cause uneven stress, and lodging is common during maturity, making it difficult for single-layer cutting and conveying devices to effectively cut the reeds, resulting in missed harvests. Summary of the Invention

[0004] To address the aforementioned technical problems, one objective of this invention is to provide a lateral conveying device for harvesting reeds. This device employs an upper, middle, and lower three-layer lateral conveying mechanism, each equipped with a lever or teeth. By collecting data on the height of the lateral conveying mechanism, the cutter, and the reeds, the height of the lateral conveying mechanism can be automatically adjusted. This enables neat and orderly lateral conveying of the reeds, improving the harvester's conveying efficiency. Furthermore, this device is applicable to the harvesting of other tall crops.

[0059] A reed harvester includes the aforementioned reed harvesting lateral conveying device.

[0060] Compared with the prior art, the beneficial effects of the present invention are:

[0061] According to one aspect of the present invention, a three-layer transverse conveying mechanism is adopted, with fingers or teeth on each of the three layers. This can address the uneven force caused by the height of the reeds and the fact that they often fall over during the maturity period, making it easier to convey the reeds and facilitating effective cutting.

[0062] According to one aspect of the present invention, a cutter height sensor and a height sensor are used to collect the height of the cutter and the lateral conveying mechanism. Based on the height of the reeds collected manually, the height of the lateral conveying mechanism can be adjusted automatically to ensure that the center of gravity is stressed when the reeds are being conveyed, and to avoid the reed stems breaking due to uneven stress in the middle. This can achieve neat and orderly lateral conveying of reed crops and improve the conveying efficiency of the harvester.

[0063] According to one aspect of the present invention, a reed-separating ring is added to the outer ring of the conveyor chains of the upper and middle transverse conveyor mechanisms. The function of the reed-separating ring is to prevent reed stalks from entering the conveyor chain and causing structural jamming and conveying failure. In addition, the reed-separating ring can also provide support for the teeth on the conveyor chain, preventing them from bending and deforming downwards during the conveying of reeds.

[0064] According to one aspect of the present invention, a tight thread is added to the outer diameter of the conveying roller to increase the friction between the roller and the belt. When the upper, middle and lower three-layer conveying mechanisms convey the stalks to the vicinity of the roller, the high-friction belt can play an auxiliary conveying role.

[0065] Note that the description of these effects does not preclude the existence of other effects. One aspect of the invention does not necessarily have all the aforementioned effects. Effects other than those described above can be readily observed and extracted from the description, drawings, claims, etc. Attached Figure Description

To ensure that the pushing range of the upper transverse conveyor mechanism 102-4 and the middle transverse conveyor mechanism 102-5 is consistent with the cutting width of the harvester's header (if they are inconsistent, the harvester can only harvest from one side), the short-side conveyor chain 102-7 and the harvester cab must be arranged on the same side.

The lower support column 102-28 is welded to the lower support frame 102-27 and is bolted to the support arm 102-29, which can be bolted to the harvester frame to support the lower support frame 102-27.

[0122] According to this embodiment, preferably, during operation, the guide fingers 102-26 move along the conveyor belt's trajectory, thereby guiding the stem roots from both sides towards the center. Simultaneously, the lower guide fingers 102-26 are installed at a lower position to support the fallen reed stems. The number of guide fingers 102-26 should completely cover the reed stems to be harvested, ensuring that every cut reed stem is collected, clamped, and conveyed by the lower guide fingers without any omissions.

[0136] V g This represents the vertical velocity component of the cut reed stalk.

[0137] According to this embodiment, preferably, the teeth 102-15 of the upper transverse conveying mechanism 102-4 and the middle transverse conveying mechanism 102-5 are bolted to the inner chain plate 102-14 of the conveying chain for collecting, clamping, and conveying reed crop stalks. During operation, the teeth 102-15 move along the trajectory of the conveying chain 102-13, thereby pushing the top and middle stalks on the reed dividing ring 102-18 from both sides towards the center. The number of teeth 102-15 should cover all the reed crop stalks to be harvested, ensuring that every reed stalk is collected, clamped, and conveyed by the teeth 102-15 without any omissions. The number q of the teeth satisfies the following condition:

[0138] q=vtlρ

[0139] Where: q represents the number of teeth 102-5;

[0140] v represents the forward speed of the harvester;

[0141] t represents a single harvest cycle;

[0142] l indicates the cutting width of the harvester's header;

[0143] ρ represents the growth density of the reeds to be harvested.

[0144] like Figure 6 As shown, the reed crop harvesting lateral conveying device also includes a cutter height sensor 103-1; the cutter height sensor 103-1 is connected to the control unit;

[0145] The lidar 104 is used to detect the height of the reeds before cutting and transmit it to the control unit, which calculates the average height h of the reeds.

[0146] The cutter height sensor 103-1 is used to detect the height h1 of the cutter 103 and transmit the data to the control unit;

[0147] like Figure 7 As shown, the control unit is based on the average height h of the reeds. avg Calculate the actual harvested reed length h2 = h based on the cutter height h1. avg The value -h1 can be used to determine the actual height of the harvested reeds and their current center of gravity. Based on the detection information from height sensor 102-1 and displacement sensor 102-3, the deviation between the height sensor 102-1 of the interlayer transverse conveyor device and the current center of gravity of the harvested reeds is calculated. The extension / retraction of the hydraulic cylinder group 102-17 of the transverse conveyor device is adjusted according to this deviation, so that the current height of the interlayer transverse conveyor mechanism 102-5 is aligned with the current center of gravity of the reeds, which is also the actual length. Then make the call.

[0148] According to this embodiment, preferably, the average height of the reeds can be measured by conventional field sampling methods, including the five-point sampling method, the diagonal sampling method, etc. After selecting the reeds, the average height h of the sampled reeds is calculated by manually cutting them. avg .

[0149] This invention employs a three-layer transverse conveying mechanism (upper, middle, and lower), each equipped with a guide finger or tooth. This addresses the uneven stress caused by the height of the reeds and the tendency for them to lodging during maturity, making the reeds easier to transport and effectively cut. Simultaneously, a cutter height sensor and a height sensor collect data on the height of the reeds, the cutter, and the transverse conveying mechanism. The height of the transverse conveying mechanism can be automatically adjusted to ensure proper center of gravity during reed transport, preventing uneven stress on the reed stems and breakage. This allows for neat and orderly transverse transport of the reeds, improving the harvester's conveying efficiency.
