Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a crop divider of a harvester and a harvester cutting platform. Background Art

[0002] In the existing harvesting process, due to the main crops grown and the terrain, different types of harvester straw dividers need to be adapted to meet the crop harvesting and usage habits in different regions. For example, the Northeast and Northwest regions prefer to use longer straw dividers, while the Central Plains region is accustomed to using short straw dividers to harvest crops. When harvesting fallen crops, the long straw divider can obviously better lift the crop stalks and feed them into the harvesting table, but the short straw divider does not have this advantage. However, the efficiency of the short straw divider's straw chain in feeding crops directly into the harvesting table is better than that of the long straw divider. Therefore, according to the growth conditions of the crops, the straw divider of the harvester needs to be adjusted during operation to improve operating efficiency.

[0003] The harvester dividers provided in the prior art are independently designed and installed with long and short dividers. For different harvesting scenarios, the dividers need to be disassembled and replaced by operators, but the replacement steps are often complicated. Therefore, during the operation, only the official dividers configured at the factory are used. In special operation scenarios, the operation efficiency of the harvester is greatly reduced.

[0004] Therefore, it is necessary to provide a straw divider for a harvester that can quickly adjust the length of the straw divider to meet the harvesting and use needs of different regions and different usage scenarios. Utility Model Content

Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0035] See also Figures 1 to 5 As shown, the utility model provides a straw divider for a harvester, with the direction in which the harvester is moving as the front, comprising a middle straw divider shell 10, the middle straw divider shell 10 cover is arranged above the straw chain to feed crops to the rear; a first straw divider 20, the first straw divider 20 is connected to the front end of the middle straw divider shell 10, and is used to divide crops; a second straw divider 30, the second straw divider 30 is arranged above the first straw divider 10, and the second straw divider 30 can be axially located in the direction of the left and right sides above the end of the first straw divider 20, and a cover that can rotate up and down is arranged above the first straw divider 20, thereby controlling the first straw divider 20 to work independently or the second straw divider 30 to work independently.

[0036] During the operation of the harvester, in order to realize the rapid switching of the crop divider, a second crop divider 30 is provided above the first crop divider 20. By rotating and disassembling the second crop divider 30, the use requirements of the harvester in different scenarios can be met. Figure 1 As shown, the front end of the middle crop divider housing 10 is connected to the first crop divider 20. Above the end of the first crop divider 20, the second crop divider 30 rotates up and down with the left and right sides of the first crop divider 20 as the axis, and the length of the second crop divider 30 is always longer than the first crop divider 20. When the second crop divider 30 rotates to the top of the first crop divider 20, the harvester is in a state of transfer. For example, if the harvester is driven from one harvesting field to another, the second crop divider 30 needs to be lifted. Because the length of the second crop divider 30 in the horizontal direction is longer than that of the first crop divider 20, in order to facilitate transfer, the second crop divider 30 is often rotated to the top of the first crop divider 20 to improve the transfer safety. When harvesting general crops, the first crop divider 20 or the second crop divider 30 is selected for harvesting operations according to the usage habits and crop types in different regions. A harvester equipped with two types of crop dividers has strong adaptability and more targeted harvesting operations.

[0037] Preferably, the first crop divider 20 includes a first crop divider body 21 and a first crop divider tip 22, and the first crop divider tip 22 is connected to the front end of the first crop divider body 21; the second crop divider 30 includes a second crop divider body 31 and a second crop divider tip 32, and the second crop divider tip 32 is connected to the front end of the second crop divider body 31. In order to facilitate the process of harvesting, the crops are pushed to the rear of the harvester, the first crop divider 20 includes the first crop divider body 21 and the first crop divider tip 22, and the harvester's crop-pushing chain is located below the first crop divider body 21. The crops are divided by the first crop divider tip 22, and the crop-pushing chain arranged below the first crop divider body 21 pushes the crops to the rear of the harvester for further operation. Since the first crop divider body 21 covers the crop chain, the crop blade of the crop chain has a larger contact surface with the crop, and since the second crop divider body 30 is longer than the first crop divider body 21, the contact range between the harvester crop chain and the crop is reduced. Therefore, the first crop divider 20 can be used to quickly move the crops to the rear of the harvester. Similarly, the harvester second crop divider 30 includes a second crop divider body 31 and a second crop divider tip 32. Compared with the first crop divider 20, the second crop divider body 31 is longer and the second crop divider tip 32 is more upturned. This configuration is to better lift the crops. When harvesting fallen crops, the second crop divider 30 is used for harvesting, which is more efficient.

[0038] Preferably, the first crop divider body 21 includes a rear cover wall 212 and a first crop divider cover plate 211, wherein the rear cover wall 212 is connected to the middle crop divider housing 10, and the first crop divider cover plate 211 is connected to the rear cover wall 212; the first crop divider tip 22 is connected to the first crop divider cover plate 211. The first crop divider tip 22 is fixed to the first crop divider cover plate 211, and usually the first crop divider cover plate 211 and the first crop divider tip 22 are fixed with screws.

[0039] Preferably, the first crop divider cover plate 211 includes a connecting groove 2111, which is arranged at the connection between the rear cover wall 212 and the first crop divider cover plate 211; the second crop divider body 31 includes a connecting portion 313, which is embedded in the connecting groove 2111 to achieve the connection between the first crop divider body 21 and the second crop divider body 31. The connecting groove 2111 is arranged at the connection between the rear cover wall 212 of the first crop divider 20 and the first crop divider cover plate 211 to connect the second crop divider 30, and the connecting groove 2111 is arranged on the first crop divider cover plate 211. Specifically, the connecting portion 313 is arranged on the second crop divider body 31 to facilitate the connection between the second crop divider 30 and the first crop divider 20, and the connecting portion 313 of the second crop divider 30 is fixed by bolts by being embedded in the connecting groove 2111.

[0040] The second crop divider body 31 includes a second crop divider cover plate 311 and side walls 312 disposed at both ends of the second crop divider cover plate 311; the second crop divider body 31 includes a support beam 314 disposed on the back of the second crop divider body 31, and the support beam 314 is connected to the first crop divider body 21. It should be noted that the side walls 312 disposed at both ends of the second crop divider cover plate 311 are not connected to the first crop divider 20. At the same time, the support beam 314 is connected to the first crop divider body 21, and the support beam 314 disposed on the second crop divider 30 plays a supporting role for the second crop divider body 31, so that the second crop divider 30 is more robust during the crop pulling process.

[0041] The support beam 314 includes a support bolt 3141 , and the support bolt 3141 abuts against the front end of the first crop divider cover plate 211 to achieve the connection between the first crop divider body 21 and the second crop divider body 31 .

[0042] When the second crop divider 30 is covered above the first crop divider 20, the first crop divider tip 22 is removed. In the process of using the second crop divider 30, in order to prevent the second crop divider 30 from rotating and tilting up, the second crop divider 30 is often fixed to the first crop divider body 21, which is specifically achieved by setting a support beam 314 on the back of the second crop divider cover 311, and the support beam 314 is fixed to the front end of the first crop divider cover 211. A support bolt 3141 is set on the support beam 314, and the first crop divider body 21 is fixed between the end of the second crop divider 30 and the support beam 3141 by adjusting the tightness of the support bolt 3141. At the same time, the second crop divider 30 also supports the second crop divider body 31 during the use of the first crop divider 20. In the process of using the second crop divider 30, that is, when the second crop divider 30 is covered above the first crop divider body 21, the first crop divider tip 22 is removed.

[0043] When it is necessary to switch between different crop dividers to harvest crops, for the use of the first crop divider 20, the bolts used for fixing the connecting portion 313 and the connecting groove 2111 are removed, and the first crop divider tip 22 is installed; for the use of the second crop divider 30, the first crop divider tip 22 is removed, and the second crop divider 30 is connected to the first crop divider 20. Arranging two crop dividers of different specifications on the same harvester header can adapt to various harvesting scenarios and has a wider range of applications.

[0044] Preferably, the first crop divider 20 includes a baffle 23, which is connected to the rear cover wall 212 and is disposed on both sides of the rear cover wall 212. In order to smoothly feed the crops during the crop pulling process, the baffle 23 is connected and fixed to the rear cover wall 212 via a pressing sheet 231. Specifically, to reduce the damage to the crops, the baffle 23 is made of rubber.

[0045] Preferably, the first crop divider 20 includes a mounting seat 24, the edges of which are connected to the first crop divider cover plate 211 and the rear cover wall 212; the mounting seat 24 is connected to the front end of the middle crop divider housing 10. Specifically, the mounting seat 24 supports the first crop divider body 21, and the sides of the mounting seat 24 are respectively connected to the first crop divider cover plate 211 and the first crop divider rear cover wall 212. At the same time, the connecting portion 313 of the second crop divider 30 also passes through the connecting groove 2111 on the first crop divider 20 and is fixed to the mounting seat 24 by bolts. In order to make the first crop divider 20 and the middle crop divider housing 10 more firmly connected, the mounting seat 24 is fixed to the base 11 at the bottom of the middle crop divider housing 10 by a fixing hook 241.

[0046] The embodiment also provides a harvester header, which is equipped with the above-mentioned harvester straw divider and has the advantages of wide range of use, strong adaptability and high harvesting efficiency.

[0047] By mounting two types of straw dividers on the harvester at the same time, it is possible to quickly adjust from one straw divider to another when facing different harvesting areas and different crops. For example, when dealing with fallen crops, it is possible to quickly switch to the second straw divider 30. The operation is simple and can improve the operating efficiency of the harvester.

[0048] It will be apparent to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention covers modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
