Description

Technical Field

[0001] This utility model relates to the field of harvester technology, and in particular to a grain-picking tooth chain structure, a corn ear-picking header, and a corn harvester. Background Technology

[0002] The reeling tooth is one of the key components of a harvester for harvesting crops. It is usually installed on the reeling chain. During the operation of the equipment, the reeling tooth comes into contact with the crop and pushes the crop toward the cutter, so that the crop can be effectively cut and transported to its processing device.

[0003] For example, Chinese Patent No. CN220422499U discloses a novel grain conveying mechanism, a header, and a corn harvester. The grain conveying mechanism includes multiple conveying units that are evenly spaced and arranged side by side. Each conveying unit includes two grain chain assemblies that are distributed opposite each other and can rotate towards each other. Multiple teeth are evenly spaced on each of the two grain chain assemblies along their own rotation direction. The size of the teeth on the two grain chain assemblies that are close to each other in two adjacent conveying units is not the same.

[0004] The aforementioned crop conveying mechanism transports crops through the counter-rotating cooperation of two adjacent conveying units. Simultaneously, the lengths of the multiple teeth on the two cooperating conveying units are inconsistent to improve stalk feeding. However, just as the teeth on the same conveying chain assembly in the aforementioned mechanism are all at the same height, existing conveying chains have teeth of uniform height. When harvesting corn plants using this type of tooth chain structure, the relatively fragile corn stalks after maturity experience a higher rate of stalk breakage during transport. Furthermore, the ears of corn suffer kernel damage due to the impact of the teeth at the same height, leading to a decrease in overall harvesting efficiency and quality. Utility Model Content

[0005] This utility model provides a reeling tooth chain structure, a corn ear-picking header, and a corn harvester, which can improve the technical problems of existing reeling tooth chain structures that are prone to stalk breakage, poor feeding, and ear and kernel damage during corn harvesting, resulting in reduced harvesting efficiency and quality.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a reeling tooth chain structure, including a reeling chain, a plurality of first reeling teeth and a plurality of second reeling teeth. Each of the first reeling teeth and each of the second reeling teeth is fixedly connected to the reeling chain and located on the same side of the reeling chain. The height of the first reeling teeth is greater than the height of the second reeling teeth. Each of the first reeling teeth and each of the second reeling teeth is distributed at intervals. Two adjacent first reeling teeth form an arrangement space, and each of the second reeling teeth is distributed in each arrangement space.

[0007] The beneficial effects of this utility model are as follows: During the harvesting process, the first and second harvesting teeth form a combined guiding function. The relatively long first harvesting teeth can ensure the transmission efficiency of the harvesting tooth chain, while the relatively short second harvesting teeth can reduce the frequency of impacting corn kernels and the rate of stalk breakage. This allows for better contact between the harvesting teeth and the crop, improving the adaptability of the equipment. This improves the technical problem that existing harvesting tooth chain structures are prone to stalk breakage, poor feeding, and damage to ears and kernels during corn harvesting, leading to reduced harvesting efficiency and quality.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, each of the aforementioned arrangement spaces is equipped with a second reel tooth.

[0010] Furthermore, at least two second reeling teeth are arranged at intervals in each of the arrangement spaces, and the number of second reeling teeth in each arrangement space is equal.

[0011] Furthermore, each of the arrangement spaces is provided with at least one second reeling tooth, and the number of second reeling teeth in at least one arrangement space is not equal to the number of second reeling teeth in at least some of the other arrangement spaces.

[0012] Furthermore, a first spacing is formed between the first reeling tooth and the adjacent second reeling tooth, and a second spacing is formed between two adjacent second reeling teeth, wherein the first spacing is equal to the second spacing.

[0013] Furthermore, each of the second reeling teeth includes two opposing tooth plates and a connecting plate whose two ends are respectively fixedly connected to the two tooth plates, and the two ends of the two tooth plates are rotatably connected to the links of the reeling chain.

[0014] Furthermore, the number of the second reeling teeth in each of the aforementioned arrangement spaces does not exceed three.

[0015] This utility model also provides a corn ear-picking cutter, including two of the aforementioned reaping tooth chain structures, the two reaping chains being spaced apart and forming a conveying space between them, with each of the first reaping teeth and each of the second reaping teeth facing the conveying space.

[0016] Furthermore, the first and second reeling teeth on the two reeling chains are alternately distributed.

[0017] This utility model also provides a corn harvester, including the aforementioned corn ear-picking and cutting platform. Attached Figure Description

[0018] Figure 1 This is a first partial structural diagram of the reeling tooth chain structure of this utility model; Figure 2 This is a second partial structural diagram of the reeling tooth chain structure of this utility model; Figure 3 for Figure 2 A partial structural diagram; Figure 4 This is a top view of the corn ear-picking and cutting platform of this utility model.

[0019] The attached diagram lists the components represented by each number as follows: 1. Rice-reeling chain; 2. First rice-reeling tooth; 3. Second rice-reeling tooth. Detailed Implementation

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] Example 1 like Figures 1-3 This utility model provides a reeling tooth chain structure, including a reeling chain 1, a plurality of first reeling teeth 2 and a plurality of second reeling teeth 3. Each first reeling tooth 2 and each second reeling tooth 3 is fixedly connected to the reeling chain 1 and located on the same side of the reeling chain 1. The height of the first reeling tooth 2 is greater than the height of the second reeling tooth 3. Each first reeling tooth 2 and each second reeling tooth 3 are distributed at intervals. Two adjacent first reeling teeth 2 form an arrangement space, and each second reeling tooth 3 is distributed in each arrangement space.

[0022] When in use, the reeling chain 1 operates, driving each first reeling tooth 2 and each second reeling tooth 3 to move simultaneously, thereby guiding the crops. In the specific guiding process, the crops can enter each arrangement space and enter the space between two adjacent second reeling teeth 3, or between the first reeling teeth 2 and the second reeling teeth 3, thus achieving the reeling.

[0023] During the harvesting process, the first and second reeling teeth 2 and 3 work together to guide the harvesting process. The relatively longer first reeling teeth 2 ensure the transmission efficiency of the reeling tooth chain, while the relatively shorter second reeling teeth 3 reduce the frequency of impact on corn kernels and the rate of stalk breakage. This allows for better contact between the reeling teeth and the crop, improving the adaptability of the equipment. This addresses the technical problem of existing reeling tooth chain structures being prone to stalk breakage and ear and kernel damage during corn harvesting, which leads to reduced harvesting efficiency and quality.

[0024] Each of the second reeling teeth 3 includes two opposing tooth plates 31 and a connecting plate 32 whose two ends are respectively fixedly connected to the two tooth plates 31. Both ends of the two tooth plates 31 are rotatably connected to the links of the reeling chain 1.

[0025] A first spacing a is formed between the first reaping tooth 2 and the adjacent second reaping tooth 3, and a second spacing b is formed between two adjacent second reaping teeth 3. The first spacing a is equal to the second spacing b.

[0026] The distance between adjacent reeling teeth is equal, so that each first reeling tooth 2 and each second reeling tooth 3 can effectively reel the crop.

[0027] In addition, it should be noted that the fixed connection structure between the first reeling tooth 2 and the second reeling tooth 3 and the reeling chain 1 is a connection method known to those skilled in the art, therefore, this utility model will not describe it in detail here.

[0028] The height difference between the first reeling tooth 2 and the second reeling tooth 3 is greater than 35mm and less than 40mm. Specifically, the height difference can be 35mm, 36mm, 37mm, 38mm, 39mm, or 40mm, etc. This ensures that each of the first reeling teeth 2 can effectively reel the crop, while reducing the frequency of impact on corn kernels and the rate of stalk breakage through the shorter second reeling teeth 3.

[0029] In this embodiment, the number of second reeling teeth 3 in each arrangement space shall not exceed three, in order to prevent the distance between two adjacent first reeling teeth 2 from being too long, which would reduce the reeling effect of the two adjacent first reeling teeth 2 on the crop. In this embodiment, the number of second reeling teeth 3 in the arrangement space can be one, two or three.

[0030] like Figure 1 As one of the parallel schemes in this embodiment, a second reeling tooth 3 is arranged in each arrangement space, that is, the second reeling tooth 3 is located in the middle of the two first reeling teeth 2 to ensure reeling efficiency.

[0031] like Figure 2 and Figure 3 As a second parallel scheme in this embodiment, at least two second reeling teeth 3 are arranged at intervals in each arrangement space, and the number of second reeling teeth 3 in each arrangement space is equal. In this second scheme, the number of two second reeling teeth 3 in each arrangement space can specifically be two, three, four, or five, etc. As a third parallel scheme of this embodiment, at least one second reeling tooth 3 is arranged in each arrangement space, and the number of second reeling teeth 3 in at least one arrangement space is not equal to the number of second reeling teeth 3 in at least some of the other arrangement spaces.

[0032] Specifically, as an example, the number of second reaping teeth 3 in each arrangement space is different. The number of second reaping teeth 3 in one arrangement space can be one, the number of second reaping teeth 3 in adjacent arrangement spaces can be two, and the number of second reaping teeth 3 in other arrangement spaces can be three.

[0033] As a second example, the number of second reaping teeth 3 in each arrangement space can be arranged in a manner of 2, 3, 2, 3, 2... or a similar manner.

[0034] Example 2 like Figure 4 Embodiment 2 of this utility model provides a corn ear-picking cutting platform, including two hoe chain structures as described in Embodiment 1. The two hoe chains 1 are spaced apart and form a conveying space between them. Each first hoe tooth 2 and each second hoe tooth 3 faces the conveying space.

[0035] During the operation, the two reeling chains 1 operate simultaneously. Under the combined action of the first reeling teeth 2 and the second reeling teeth 3 on the two reeling chains 1, the work is continuously guided and transported in the conveying space.

[0036] In this system, the first reeling teeth 2 and the second reeling teeth 3 on the two reeling chains 1 are alternately distributed. This reduces the large "vacuum zones" without reeling teeth that occur between the two reeling chains 1 due to the intervals between the reeling teeth, ensuring that the crop is transported efficiently by the action of each reeling tooth.

[0037] Example 3 This embodiment three provides a corn harvester, including the corn ear picking and cutting platform described in embodiment two.
