Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a grain lifting system and a harvester. Background Art

[0002] As the feed volume of harvesters continues to increase, harvesters are continuously developing towards larger sizes, and grain tanks are also increasing their capacity by adding grain tank covers. However, in the current grain elevator structure of harvesters, the grain elevator's grain lifting barrel and the grain lifting gear box that are adapted to the grain tank cover structure mostly use an open connection. When the grain tank cover is closed, the grain lifting barrel is disconnected from the grain lifting gear box, and the grain lifting barrel cannot discharge the material transported by the grain elevator. Continuing to harvest will cause the grain elevator to become blocked, making it impossible to close the cover and harvest the grain. In some special plots, such as when there are high-voltage transmission lines in the plot, the grain tank cover needs to be closed during the harvest process to avoid interference with the transmission lines, but closing the cover prevents continued operation.

[0003] Therefore, it is urgent to provide a grain lifting system and a harvester to solve the problems in the prior art to a certain extent. Utility Model Content

[0034] like Figure 1 As shown, the utility model provides a grain lifting system for a harvester, comprising a lifting mechanism 1, a transmission mechanism, a grain lifting barrel assembly 2 and a linkage mechanism 16; the feeding end of the lifting mechanism 1 is located outside the material box 5 of the harvester, and the discharging end is located inside the material box 5 and is connected to one end of the transmission mechanism, the grain lifting barrel assembly 2 is rotatably connected to the other end of the transmission mechanism, one end of the linkage mechanism 16 is connected to the flip cover of the material box 5, and the other end is connected to the outer wall of the grain lifting barrel assembly 2.

[0035] Compared with the existing technology, the grain lifting system provided by the utility model has the following advantages:

[0036] The grain lifting system provided by the present invention enables the discharge end of the lifting mechanism 1 to be located in the material box 5 and connected to one end of the transfer mechanism, while the other end of the transfer mechanism is connected to the grain lifting cylinder assembly 2, so that the material transported by the lifting mechanism 1 can be transferred to the grain lifting cylinder assembly 2 and discharged into the material box 5 through the discharge port of the grain lifting cylinder assembly 2, thereby realizing the transportation of the material.

[0037] In some special plots, when the cover of the material box 5 needs to be closed, since a linkage mechanism 16 is connected between the grain lifting barrel assembly 2 and the cover in this application, and the grain lifting barrel assembly 2 is rotationally connected to the transmission mechanism, when the cover rotates from the open state to the closed state, it can drive the linkage mechanism 16 to move, thereby pushing the grain lifting barrel assembly 2 to rotate relative to the transmission mechanism, causing the grain lifting barrel assembly 2 to deflect, and then there will be no interference between the discharge port of the grain lifting barrel assembly 2 and the cover, and the material transported by the lifting mechanism 1 can continue to be discharged from the discharge port. Therefore, the grain lifting system provided by this application can not only complete the grain feeding function in the open cover state, but also continue to operate in the closed cover state, so that the overall harvester can be better adapted to different plots and avoid the problem of difficult operation in height-restricted plots.

[0038] It should be noted here that the linkage mechanism 16 in the present application can adopt a foldable transmission connecting rod, and one end is rotatably connected to the flip cover, and the other end is rotatably connected to the grain lifting cylinder assembly 2. When the flip cover is opened or closed, the foldable connecting rod can apply a push or pull force to the grain lifting cylinder assembly 2, thereby realizing the rotation of the grain lifting cylinder assembly 2 relative to the transmission mechanism.

[0039] Alternatively, as Figure 1As shown, the material box 5 in the present application includes a box body 501 and a flip cover, the flip cover includes a first cover body 502, a second cover body 503, a third cover body 504 and a fourth cover body 505; the box body 501 is a rectangular structure, the first cover body 502 and the second cover body 503 are relatively arranged on two parallel sides of the box body 501, the third cover body 504 and the fourth cover body 505 are relatively arranged on the other two parallel sides of the box body 501, and the first cover body 502, the second cover body 503, the third cover body 504 and the fourth cover body 505 are all rotatably connected to the box body 501 to close or open the opening of the box body 501.

[0040] The first cover 502 and the second cover 503 in the present application mainly cover the opening of the box body 501, that is, the sum of the areas of the first cover 502 and the second cover 503 is the same as the opening area of ​​the material box 5, so that the opening of the material box 5 can be closed, and the main function of the third cover 504 and the fourth cover 505 is to be connected between the first cover 502 and the second cover 503. When the first cover 502, the second cover 503, the third cover 504 and the fourth cover 505 are all opened, the volume of the overall material box 5 can be increased and the carrying capacity can be improved.

[0041] Preferably, in the present application, the first cover body 502, the second cover body 503, the material box 5 also includes a driving member and a connecting rod assembly, the connecting rod assembly includes a driving rod 6, a first linkage member 10, a second linkage member 11, a first transmission rod 7, a second transmission rod 8, a third transmission rod 9, a third linkage member 12, a fourth linkage member 13, a fifth linkage member 14 and a sixth linkage member 15; the driving end of the driving member is connected to the driving rod 6 to drive the driving rod 6 to rotate, one end of the first linkage member 10, the second linkage member 11 and the third linkage member 12 are all fixedly connected to the driving rod 6, the other end of the first linkage member 10 is fixedly connected to the first transmission rod 7, and the other end of the second linkage member 11 is fixedly connected to the The second transmission rod 8 is fixedly connected, and the other end of the third linkage member 12 is connected to the fourth cover body 505; the linkage mechanism 16 includes two parts, the first end of the first part is fixedly connected to the first transmission rod 7, and the second end is connected to the first cover body 502, the first end of the second part is rotatably connected to the first cover body 502, and the second end is rotatably connected to the grain lifting barrel assembly 2; one end of the fourth linkage member 13 is fixedly connected to the first transmission rod 7, and the other end is fixedly connected to the third transmission rod 9, one end of the fifth linkage member 14 is fixedly connected to the third transmission rod 9, and the other end is connected to the third cover body 504; one end of the sixth linkage member 15 is fixedly connected to the second transmission rod 8, and the other end is connected to the second cover body 503.

[0042] The driving component in this application can adopt a driving device such as a motor to directly drive the driving rod 6 to rotate, or it can adopt a telescopic structure with a small size and larger output force such as a cylinder or an oil cylinder. When a cylinder or an oil cylinder is used, a connecting plate needs to be further added between the output end of the driving component and one end of the driving rod 6. When the driving component is extended, it can drive one end of the connecting plate to move, thereby realizing the rotation of the driving rod 6.

[0043] Accordingly, if Figure 1 As shown, one end of the first linkage member 10, the second linkage member 11 and the third linkage member 12 in the present application are all fixedly connected to the drive rod 6, and the structures of the first linkage member 10, the second linkage member 11 and the fourth linkage member 13 in the present application are the same, and the structures of the third linkage member 12, the fifth linkage member 14 and the sixth linkage member 15 are the same.

[0044] Preferably, if Figure 1 As shown, the first linkage member 10 and the second linkage member 11 in the present application both include a first connecting seat 1001, a first push rod 1003 and a second connecting seat 1002, and the fourth linkage member 13 includes a third connecting seat 1301, a second push rod 1303 and a fourth connecting seat 1302; one end of the first connecting seat 1001 is fixedly connected to the driving rod 6, one end of the first push rod 1003 is fixedly connected to the first connecting seat 1001, and the other end is fixedly connected to one end of the second connecting seat 1002, and the other end of the second connecting seat 1002 is fixedly connected to the first transmission rod 7; one end of the third connecting seat 1301 is fixedly connected to the first transmission rod 7, one end of the second push rod 1303 is fixedly connected to one end of the third connecting seat 1301, and the other end is fixedly connected to one end of the fourth connecting seat 1302, and the other end of the fourth connecting seat 1302 is fixedly connected to the third transmission rod 9.

[0045] When the driving rod 6 rotates, the first connecting seat 1001 rotates along with the driving rod 6, thereby driving the first push rod 1003 connected to the first connecting seat 1001 to push downward or pull upward the second connecting seat 1002. Since the second connecting seat 1002 in this application is fixedly connected to the first transmission rod 7, the change of rotation direction and the transmission of power can be achieved through the first connecting seat 1001, the second connecting seat 1002 and the first push rod 1003.

[0046] When the first transmission rod 7 rotates, the third connecting seat 1301 connected to the first transmission rod 7 rotates synchronously, thereby driving the fourth connecting seat 1302 to rotate through the second push rod 1303. Since the fourth connecting seat 1302 in this application is fixedly connected to the third transmission rod 9, the change of rotation direction and the transmission of power can be achieved through the third connecting seat 1301, the fourth connecting seat 1302 and the second push rod 1303.

[0047] Correspondingly, since the second linkage member 11 in the present application has the same structure as the first linkage member 10 , it can synchronously drive the second transmission rod 8 to rotate.

[0048] It can be understood that since the driving rod 6, the first transmission rod 7, the second transmission rod 8 and the third transmission rod 9 are respectively connected to the third linkage member 12, the linkage mechanism 16, the fifth linkage member 14 and the sixth linkage member 15, and the linkage mechanism 16 in this application has the same parts as the third linkage member 12, the fifth linkage member 14 and the sixth linkage member 15, therefore, when the driving rod 6, the first transmission rod 7, the second transmission rod 8 and the third transmission rod 9 rotate synchronously, they can drive the third linkage member 12, the linkage mechanism 16, the fifth linkage member 14 and the sixth linkage member 15 to drive the first cover 502, the second cover 503, the third cover 504 and the fourth cover 505 to rotate relative to the box body 501, thereby realizing the opening or closing of the box body 501.

[0049] It should be noted here that the linkage mechanism 16 in the present application has the same parts as the third linkage member 12, the fifth linkage member 14 and the sixth linkage member 15, that is, the third linkage member 12, the linkage mechanism 16, the fifth linkage member 14 and the sixth linkage member 15 in the present application all include a first link 1201 and a second link 1202, the first link 1201 and the second link 1202 are rotatably connected to form a folding structure, one end of the second link 1202 is connected to the corresponding cover body, and the first link 1201 is connected to the corresponding drive rod 6 and the transmission rod, so that the four cover bodies can be opened or closed.

[0050] In addition to the first connecting rod 1201 and the second connecting rod 1202, the linkage mechanism 16 in the present application also includes a pushing rod 1601. When the first connecting rod 1201 and the second connecting rod 1202 are folded, the first cover body 502 can be closed, so that the movement of the first cover body 502 drives the pushing rod 1601 to move, thereby achieving the purpose of pushing the grain lifting barrel assembly 2 to rotate, that is, when the first cover body 502 is opened, the pushing rod 1601 can pull the grain lifting barrel assembly 2 to rotate to a vertical state relative to the adapter assembly 4, and when the first cover body 502 is closed, the pushing rod 1601 can push the grain lifting barrel assembly 2 to rotate to an inclined state relative to the adapter assembly 4, so that the discharge port is offset to avoid the flip cover, thereby achieving continuous grain discharge in the closed state.

[0051] Alternatively, as Figure 2 Combine Figure 3 As shown, the transmission mechanism includes a horizontal conveying component 3 and a transfer component 4. One end of the horizontal conveying component 3 is connected to the discharge end of the lifting mechanism 1, and the other end is connected to one end of the transfer component 4. The grain lifting barrel component 2 is rotatably connected to the other end of the transfer component 4.

[0052] The horizontal conveying component 3 in the present application is arranged in the horizontal direction and is connected between the lifting mechanism 1 and the adapter component 4. The horizontal conveying component 3 in the present application includes a first cylinder 301 and a first conveying member 302. One end of the first cylinder 301 is connected to the discharge end of the lifting mechanism 1, and the other end is connected to one end of the adapter component 4. The first conveying member 302 is located in the first cylinder 301, and conveys the material input by the lifting mechanism 1 to the adapter component 4.

[0053] The first conveying member 302 in the present application is a spiral auger, which realizes the forward transportation of materials in the first cylinder 301 through the auger.

[0054] Accordingly, if Figure 2 Combine Figure 3 As shown, the grain lifting cylinder assembly 2 in the present application includes a second cylinder 201 and a second conveying component 202. One end of the second cylinder 201 is connected to one end of the adapter assembly 4, and the other end of the second cylinder 201 is a discharge port. The second conveying component 202 is located in the second cylinder 201, and conveys the material passing through the adapter assembly 4 to the discharge port of the second cylinder 201 and discharges it into the material box 5.

[0055] The second cylinder 201 in the present application extends in the vertical direction, and the second conveying member 202 also adopts a spiral auger, which realizes the forward transportation of the material in the second cylinder 201 through the spiral auger.

[0056] Alternatively, as Figure 2 Combine Figure 3 As shown, the adapter assembly 4 in the present application includes a third cylinder 401, a first bevel gear 402 and a second bevel gear 403. One end of the third cylinder 401 is rotatably connected to the end of the first cylinder 301 away from the lifting mechanism 1, and the other end is connected to the end of the second cylinder 201 away from the discharge port. The first bevel gear 402 and the second bevel gear 403 are located in the third cylinder 401, and the first bevel gear 402 is connected to the first conveying member 302, and the second bevel gear 403 is connected to the second conveying member 202.

[0057] Since the first cylinder 301 in the present application extends in the horizontal direction and the second cylinder 201 extends in the vertical direction when the cover is opened, the third cylinder 401 and the first bevel gear 402 and the second bevel gear 403 arranged in the third cylinder 401 can realize the reversing conveying of the material and the synchronous rotation of the second conveying member 202.

[0058] Preferably, if Figure 2 Combine Figure 3As shown, the axis of the first cylinder body 301 in the application extends along the horizontal direction, the axis of the second cylinder body 201 extends along the vertical direction, and the third cylinder body 401 is a bent pipe structure.

[0059] In addition, the utility model provides a harvester, including the above-mentioned grain lifting system and bin 5.

[0060] The harvester with the grain lifting system provided by the application can continue to work in the closed cover state even in the high-limited land, thereby having higher adaptability and ensuring the smoothness and efficiency of the harvesting operation.

[0061] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
