[0040] Please refer to Figures 1-6 , this embodiment provides a pulling chain 200, the pulling chain 200 includes a main chain body 210 and at least one attached plate outer link 100;

[0041] The attachment plate outer link 100 is connected to the main chain body 210; the attachment plate outer link 100 includes an attachment plate body 110 and a plucking head 120; the attachment plate body 110 includes a first outer attachment plate 111 and a second outer attachment plate 112 arranged in parallel and spaced apart, and the first outer attachment plate 111 and the second outer attachment plate 112 are both used to connect to the inner link 220 of the main chain body 210; the plucking head 120 includes a first side surface 121 and a second side surface 122 opposite to each other, the first side surface 121 is connected to the first outer attachment plate 111, and the second side surface 122 is connected to the second outer attachment plate 112; wherein the first side surface 121 and the second side surface 122 both extend in a direction away from the attachment plate body 110, and along the extension direction, the distance between the first side surface 121 and the second side surface 122 gradually decreases.

[0042] Please refer to Figures 1-6 The working principle of the pulling chain 200 using the attached plate outer link 100 is:

[0043] The pulling chain 200 is applied to the pulling chain 200 of a corn harvester. When the corn harvester is in operation, the corn divider of the corn harvester guides the stalks into the pulling chain, and the pulling chain pushes the corn plants entering the machine backwards so that they enter the working area of ​​the ear picking rollers, so that the picked ears fall into the conveyor.

[0044] During this process, since the outer link 100 of the attachment plate is connected to the main chain body 210, after being connected to the inner link 220 of the main chain body 210, it forms an integrated pulling chain 200 with the main chain body 210, and thus, during the movement of the pulling chain 200, the pulling head 120 can move with the movement of the pulling chain 200 and can deliver corn plants to the working area of ​​the ear picking roller;

[0045] To achieve the above-mentioned purpose, the attachment plate outer link 100 includes an attachment plate body 110 and a pulling head 120. The attachment plate body 110 includes a first outer attachment plate 111 and a second outer attachment plate 112 spaced apart and arranged in parallel. The spaced apart first outer attachment plate 111 and second outer attachment plate 112 facilitate connection with the inner link 220 of the main chain body 210.

[0046] The plowing head 120 includes a first side surface 121 and a second side surface 122 opposite to each other. The first side surface 121 is connected to the first outer attachment plate 111, and the second side surface 122 is connected to the second outer attachment plate 112. Both the first side surface 121 and the second side surface 122 extend away from the attachment plate body 110, and the distance between the first side surface 121 and the second side surface 122 gradually decreases along the direction of their extension. This arrangement causes the distance between the first side surface 121 and the second side surface 122 of the plowing head 120 to change along the direction of their extension. That is, the width of the plowing head 120 at the end away from the attachment plate body 110 is smaller than the width of the end connected to the attachment plate body 110. This arrangement is intended to enable the plowing head 120 to better complete the task of plowing corn plants and, in the process, to improve the stability of the corn plant's plowing. This, in turn, can improve the operational stability of the plowing chain 200, thereby improving the efficiency and quality of corn harvesting.

[0047] In addition, compared to the arrangement in which the width of the plucking head 120 remains constant along its extension direction, that is, the width of the plucking head 120 is consistent with the width of the attachment plate body, the arrangement of the plucking head 120 of the attachment plate outer link 100 can better plucking corn plants. This is because the aforementioned arrangement makes the width of the plucking head 120 at the end in contact with the corn plant smaller than the width at other locations, thereby improving the plucking stability.

[0048] It should also be noted that this arrangement not only improves its operational stability and feeding quality, but also helps to reduce the weight of the reed chain.

[0049] In summary, when the attached plate outer link 100 is applied to the pulling chain 200, the operational stability and reliability of the pulling chain 200 can be improved, and the harvesting efficiency and harvesting quality of the corn harvester can be improved.

[0050] It should be noted that the attachment plate body 110 and the plowing head 120 in this embodiment are made in an integral manner, but in other embodiments of the present invention, the attachment plate body 110 and the plowing head 120 can also be made separately and connected by welding or other means.

[0051] Further, please refer to Figures 1-6 In this embodiment, when configuring the main chain body 210 of the weeding chain 200, the main chain body 210 includes a plurality of inner chain links 220 and a plurality of outer chain links 230; the outer chain links 230 are connected to the inner chain links 220, and the attached plate outer chain links 100 are connected to the inner chain links 220. There is at least one inner chain link 220 distributed between adjacent outer chain links 230 and attached plate outer chain links 100, and the attached plate outer chain links 100, the plurality of outer chain links 230 and the plurality of attached plate outer chains are connected end to end to form a ring.

[0052] Therefore, when the attached plate outer chain link 100 is applied to the straw pulling chain 200, it can be connected in series in the structure of the main chain body 210, that is, the outer chain link 230, the inner chain link 220 and the attached plate outer chain link 100 can be arranged in a staggered order along the extension direction of the straw pulling chain 200. Specifically, since the outer chain link 230 is connected to the inner chain link 220, and the attached plate outer chain link 100 is connected to the inner chain link 220, the attached plate outer chain link 100, multiple outer chain links 230 and multiple attached plate outer chains can be connected end to end to form a ring, that is, on the basis of forming a complete chain, the inner chain link 220, the outer chain link 230, the inner chain link 220 and the attached plate outer chain link 100 are arranged in sequence along the extension direction of the straw pulling chain 200, so as to form a complete connection in this way, and there is an inner chain link 220 distributed between the outer chain link 230 and the attached plate outer chain link 100.

[0053] It should be noted that the inner links 220 and the outer links 230 of the main chain body 210 may adopt structures of the prior art.

[0054] Further, please refer to Figures 1-6 In this embodiment, when configuring the plowing head 120, the first side surface 121 can be flush with the first outer plate 111, and the second side surface 122 can be inclined toward the first side surface 121; or, the first side surface 121 can be flush with the first outer plate 111, and the second side surface 122 can be bent and extended toward the first side surface 121.

[0055] Both of the above-mentioned methods can make the distance between the first side surface 121 and the second side surface 122 gradually decrease along the extension direction of the plowing head 120 .

[0056] In order to connect the first outer attachment plate 111 and the second outer attachment plate 112, the attachment plate outer link 100 further includes two pins 130. The first outer attachment plate 111 and the second outer attachment plate 112 are each provided with a first connecting hole 113 and a second connecting hole 114 at intervals.

[0057] The first connecting hole 113 on the first outer attachment plate 111 corresponds to the first connecting hole 113 on the second outer attachment plate 112 and is interference-fitted with both ends of the same pin 130 ;

[0058] The second connection hole 114 on the first outer attachment plate 111 corresponds to the second connection hole 114 on the second outer attachment plate 112 , and are interference-fitted with both ends of the same pin shaft 130 , respectively.

[0059] When configuring the two pins 130, they can be spaced apart along the extension direction of the pulling chain 200. This allows the attachment plate body 110 to be connected to the two external inner chain links 220 based on the connection between the two pins 130 and the first outer attachment plate 111 and the second outer attachment plate 112. It should be noted that when connecting the attachment plate body 110 to the external inner chain links 220, the connection method can be the same as the connection method between the outer chain links 230 and the inner chain links 220, that is, the pins 130 can be inserted into the sleeves of the inner chain links 220. The specific connection principle will not be repeated here.

[0060] Further, please refer to Figures 1-6 In this embodiment, during the configuration of the attachment plate body 110, to reduce friction between the pin 130 of the attachment plate body 110 and external structures or materials, thereby preventing wear of the pin 130 and potentially causing operational malfunction or failure of the pulling chain 200, the first and second outer attachment plates 111 and 112 are each provided with a boss 115 projecting outward. The protruding length of the boss 115 is greater than or equal to the length of the pin 130 projecting from the first and second outer attachment plates 111 and 112. Consequently, during operation of the pulling chain 200, the boss 115 prevents materials or structures on either side of the chain 200 from contacting the pin 130, thereby reducing wear of the pin 130 and extending the service life of the pulling chain 200.

[0061] Based on the above structure, please refer to Figures 1-6 To prevent stress concentration and potential failure at the connection between the plowing head 120 and the attachment plate body 110, a first transition arc 116 is provided at the edge of the interface between the first side surface 121 and the first outer attachment plate 111, and a second transition arc 117 is provided at the edge of the interface between the second side surface 122 and the second outer attachment plate 112. This arrangement improves the operational stability and reliability of the attachment plate outer link 100.

[0062] Based on the above-mentioned outer link 100 and the weeding chain 200, please refer to Figures 1-6 This embodiment also provides a corn harvester, which includes the above-mentioned pulling chain 200.

[0063] By adopting the above-mentioned attached plate outer link 100 and the straw chain 200, the corn harvester can improve the operational stability and reliability of the corn harvester, and improve the harvesting efficiency and harvesting quality of the corn harvester.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
