Description

Technical Field

[0001] This utility model relates to the field of harvesting machinery technology, specifically to a crop harvesting machine and its divider. Background Technology

[0002] The corn ear picker is one of the important harvesting machines in modern agricultural production. Its main function is to separate and collect corn ears from the plant. The divider, as a key component of the corn ear picker, is responsible for separating the corn plants and providing a working channel for the ear picking device.

[0003] Currently, the width of the divider is fixed. With the diversification of corn planting patterns, such as wide and narrow row planting and planting with different row spacing, higher requirements are placed on the adaptability of corn harvesters. The traditional fixed-width divider can no longer meet the needs of different planting patterns. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that existing fixed-width dividers cannot meet the dividing requirements of crops (such as corn) under different planting patterns, and to provide a crop harvesting machine and its divider. The divider has an adjustment component that can adjust the width of the divider to make it suitable for use with crops (such as corn) under different planting patterns.

[0005] To achieve the above objectives, this utility model provides a divider, including a front body, a connecting body, a fixing part, and an adjusting component. The front body is connected to the connecting body, the connecting body is disposed on the adjusting component, the adjusting component is rotatably connected to the fixing part and can be fixed in different predetermined positions, and the adjusting component is used to drive the front body and the connecting body to rotate relative to the fixing part.

[0006] Preferably, the adjustment assembly includes a bracket and a connecting positioning member that are connected to each other. The connecting body is fixedly connected to the bracket, and the bracket is rotatably connected to the fixing part. The connecting positioning member has multiple connecting positions, which are arranged in an arc shape. The connecting positioning member is fixedly connected to the fixing part at different predetermined positions through the multiple connecting positions.

[0007] Preferably, the adjustment assembly further includes a connecting frame, the bracket is connected to the connecting body via the connecting frame, and at least two connecting surfaces connected to the connecting body are formed on the connecting frame.

[0008] Preferably, the adjustment assembly further includes an adapter component, which is fixedly connected to the bracket and rotatably connected to the fixing part.

[0009] Preferably, the adapter component includes an adapter rod and an adapter plate. The adapter rod is fixed parallel to the bracket, and the adapter plate is disposed at the end of the adapter rod and rotatably connected to the fixing part.

[0010] Preferably, multiple adapter plates are provided, with at least two adapter plates disposed on opposite sides of the adapter connecting rod and rotatably connected to opposite sides of the fixed part.

[0011] Preferably, the end of the connector opposite to the front body is slidably fitted to the fixing part and / or forms a rotational gap with the fixing part, so that the connector can rotate relative to the fixing part.

[0012] Preferably, the adjustment assembly further includes a first locking component, and the connection position includes a plurality of connection holes, the different connection holes being adjustablely connected to the fixing holes on the fixing part through the first locking component.

[0013] Preferably, the connecting positioning component includes multiple arc-shaped connecting positioning plates, with at least two connecting positioning plates disposed on opposite sides of the fixing part, and the connecting holes of the two connecting positioning plates being coaxially arranged in a one-to-one correspondence.

[0014] The second aspect of this utility model provides a crop harvesting machine, including the above-mentioned divider.

[0015] The above technical solution describes a crop harvesting machine that includes a pair of dividers on the left and right sides, and an intermediate divider between them. Width refers to the distance between the front bodies of the two dividers. When width adjustment is needed, for one divider, the adjusting component rotates the connecting body relative to the fixed part in a direction away from the other divider. The connecting body also rotates the front body relative to the fixed part in the same direction, increasing the distance between the front bodies of the two dividers, thus increasing the width. Similarly, the adjusting component rotates the connecting body and the front body relative to the fixed part in a direction closer to the other divider, decreasing the distance between the front bodies of the two dividers, thus decreasing the width. By operating the adjusting component according to different width requirements, the divider can be adapted to crops with different planting patterns, improving its adaptability.

Detailed Implementation

[0033] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower parts of the corresponding drawings. "Inner" and "outer" refer to the inner and outer contours of the corresponding parts.

[0034] Please refer to Figures 1 to 15 The present invention provides a divider, including a front body 10, a connecting body 20, a fixing part 30 and an adjusting component 40. The front body 10 is connected to the connecting body 20, the connecting body 20 is disposed on the adjusting component 40, the adjusting component 40 is rotatably connected to the fixing part 30 and can be fixed in different predetermined positions, and the adjusting component 40 is used to drive the front body 10 and the connecting body 20 to rotate relative to the fixing part 30.

[0035] A crop harvesting machine includes a pair of dividers on the left and right sides, and an intermediate divider between them. Width refers to the distance between the front bodies of the left and right dividers. When the width needs to be increased, for one divider, the adjusting component 40 is operated, causing it to rotate relative to the fixed part 30 in a direction away from the other divider. This causes the connecting body 20 to rotate relative to the fixed part 30 in the same direction, and the connecting body 20 causes the front body 10 to rotate relative to the fixed part 30 in the same direction, increasing the distance between the front bodies 10 of the two dividers. Similarly, when the width needs to be decreased, for one divider, the adjusting component 40 is operated, causing it to rotate relative to the fixed part 30 in a direction closer to the other divider. This sequentially causes the connecting body 20 and the front body 10 to rotate in the same direction, thus reducing the width. Different widths can be achieved by operating the adjusting component 40 for different crop planting patterns, increasing the applicability of the divider.

[0036] Since the connecting body 20 and the fixing part 30 bracket can rotate relative to each other, there is no need to lock the connecting body 20 and the fixing part 30. It is only necessary to operate the adjusting component 40 to lock the adjusting component 40 to the fixing part 30 at different adjustment positions. When adjusting, it is only necessary to remove the first locking part 46 (described in detail later) to allow the adjusting component 40 to rotate relative to the fixing part 30, which is convenient and quick to operate.

[0037] Specifically, such as Figures 2 to 9 as well as Figure 15 As shown, the precursor 10 includes a body 12 connected to the connector 20 and a head 11 that forms an angle with the body 12. The end of the body 12 away from the head 11 is fixedly connected to the connector 20 by bolts and nuts. The extension direction of the body 12 and the extension direction of the head 11 form an obtuse angle. In a pair of dividers, the head 11 of the precursor 10 forms an angle with the body 12 in the direction away from the other divider.

[0038] Reference Figure 1 , Figure 3 , Figure 4 as well as Figures 10 to 14 The adjustment component 40 includes a bracket 41 and a connecting positioning member 42 that are connected to each other. The connecting body 20 is fixedly connected to the bracket 41, and the bracket 41 is rotatably connected to the fixing part 30. The connecting positioning member 42 is provided with multiple connecting positions, which are arranged in an arc shape. The connecting positioning member 42 is fixedly connected to the fixing part 30 at different predetermined positions through the multiple connecting positions.

[0039] When the width of the divider needs to be adjusted, the corresponding connecting part of the connecting positioning member 42 is fixedly connected to the corresponding position relative to the fixed part 30 to achieve the change of width. The arc of the connecting part is the arc of the adjustment component 40 relative to the fixed part 30.

[0040] like Figure 13 and Figure 14 As shown, when this divider is applied to crop harvesting machinery (such as a corn ear picker), the support 41 is a tension sprocket support, which can be telescopic. Specifically, it includes an outer tube 411 and an inner rod 412 that slides into the outer tube 411. The end of the inner rod 412 away from the outer tube 411 is formed as a telescopic end, and the end of the outer tube 411 away from the telescopic end of the inner rod 412 is formed as a fixed end. The telescopic end of the bracket 41 is rotatably connected to a tension sprocket 47. The connection node between the adapter plate 432 (described later) and the fixed part 30 is also rotatably connected to a reeling sprocket 49. Both the tension sprocket 47 and the reeling sprocket 49 are used to mesh with the chain in the crop harvesting machinery to realize the crop harvesting operation. The adjustment component 40 also includes a tension spring 48. One end of the tension spring 48 is fixed to the inner rod 412 by a plate, and the other end is fixed to the outer tube 411 by a plate. It is also used to realize the crop harvesting operation. The tension sprocket 47, the reeling sprocket 49 and the tension spring 48 can be components in existing corn ear pickers and are not the focus of this application. They will not be described in detail here.

[0041] Reference Figures 10 to 14 The adjustment assembly 40 also includes a connecting frame 45, and the bracket 41 is connected to the connecting body 20 through the connecting frame 45. At least two connecting surfaces 451 connected to the connecting body 20 are formed on the connecting frame 45.

[0042] Specifically, the connecting frame 45 includes a "V" shaped plate and two connecting plates extending perpendicular to both sides of the "V" shaped plate. The "V" shaped plate is used to adapt to the shape of the main part 21 of the connecting body 20. The connecting surface 451 is formed on the side of the two connecting plates away from the "V" shaped plate. The connecting surface 451 is in contact with the inner cavity wall formed by the main part 21 of the connecting body 20 and is connected by bolts and nuts. The two connecting plates form two connecting surfaces 451, which increases the contact area between the connecting frame 45 and the main part 21, thereby increasing the connection stability between the two.

[0043] Reference Figure 13 and Figure 14 The adjustment assembly 40 also includes an adapter 43, which is fixedly connected to the bracket 41 and rotatably connected to the fixing part 30.

[0044] In one embodiment, the rotating component 43 is rotatably connected to the fixed part 30 by means that the adapter plate 432 of the adapter 43 is hinged to the fixed part 30.

[0045] In another embodiment, the rotatable connection between the rotating component 43 and the fixed part 30 is achieved through the second locking component 44, the first locking hole 4321, and the second locking hole. Specifically, the adjusting assembly 40 further includes the second locking component 44, the adapter 43 has the first locking hole 4321, the fixed part 30 has the second locking hole coaxial with the first locking hole 4321, and the second locking component 44 has threads for threaded connection to the first locking hole 4321 and the second locking hole, so that the adapter 43 can be rotated relative to the fixed part 30 by loosening and fixed relative to the fixed part 30 by tightening. The adapter 43 is used to rotatably connect the outer sleeve 411 of the bracket 41 to the fixed part 30. When the width needs to be adjusted, the second locking component 44 is loosened, so that the adapter 43 rotates relative to the fixed part 30 about the axis of the first locking hole 4321 and the second locking hole. After the width is adjusted to the correct position, the second locking component 44 is tightened, and the adapter 43 is fixed relative to the fixed part 30. During the width adjustment process, only the first locking component 46 (described in detail later) needs to be disassembled and the second locking component 44 needs to be loosened and tightened. The second locking component 44 does not need to be disassembled, and no other component disassembly or assembly is required, making the adjustment quicker and simpler. It also requires no complex tools or specialized knowledge from the operator, resulting in low operational requirements. The second locking component 44 can be a combination of a bolt and a nut.

[0046] Continue to refer to Figure 13 and Figure 14 The adapter component 43 includes an adapter rod 431 and an adapter plate 432. The adapter rod 431 is fixed parallel to the bracket 41, and the adapter plate 432 is disposed at the end of the adapter rod 431. A first locking hole 4321 is formed on the adapter plate 432.

[0047] In order to give the bracket 41 a sufficient range of extension, the length of the outer tube 411 is set to be relatively short. This would result in the outer tube 411 being too short to connect to the fixing part 30. Therefore, an adapter 43 is provided to connect the outer tube 411 to the fixing part 30. The length of the adapter 43 is greater than the length of the outer tube 411.

[0048] Specifically, the adapter rod 431 is fixedly connected to the outer sleeve 411, the adapter plate 432 is connected to the end of the adapter rod 431, and there is an angle between the extension direction of the adapter plate 432 and the extension direction of the adapter rod 431 to adapt to the relative positional relationship between the fixing part 30 and the adapter rod 431, that is, to connect the adapter rod 431 to the fixing part 30 through the adapter plate 432.

[0049] Reference Figure 3 , Figure 10 , Figure 13 and Figure 14 Multiple adapter plates 432 are provided, with at least two adapter plates 432 provided on opposite sides of the adapter connecting rod 431 and connected to opposite sides of the fixing part 30 through first locking holes 4321, and the first locking holes 4321 on the two adapter plates 432 are coaxial.

[0050] Specifically, such as Figure 13 and Figure 14 As shown, the fixing part 30 includes three parallel side beams 31, an inclined beam 32 and a straight beam 33 connected to the side beams 31. The three side beams 31 form a right-angled triangular prism. Multiple straight beams 33 are provided, and two side beams 31 corresponding to each right-angle side are connected by multiple parallel straight beams 33. One inclined beam 32 is provided, which is connected between two of the side beams 31. A connecting positioning member 42 is connected to the inclined beam 32. Fixing holes are formed on the fixing part 30 on the inclined beam 32 for cooperating with connecting holes 421 on the connecting positioning member 42. An adapter plate 432 is connected to the end of another side beam 31, and the two adapter plates 432 are located on opposite sides of the end of the side beam 31. A second locking hole is formed on the side beam 31. The two adapter plates 432 are connected to the side beam 31 through a second locking member 44. The provision of the two adapter plates 432 can increase the stability of the connection between the adapter member 43 and the fixing part 30. Since both the adapter rod 431 and the side beam 31 are hollow tubes, it is not convenient to achieve a rotatable connection between them. Therefore, an adapter plate 432 is provided to achieve the connection with the side beam 31.

[0051] In some embodiments, the end of the connector 20 facing away from the front body 10 is slidably fitted with the fixing part 30 and / or forms a rotational gap with the fixing part 30, so that the connector 20 can rotate relative to the fixing part 30.

[0052] Since the connecting body 20 is connected to the fixing part 30 via the adjusting component 40, the connecting body 20 and the fixing part 30 may not be connected, and a rotational clearance may be formed between them to provide sufficient space for the rotation of the connecting body 20 relative to the fixing part 30. Alternatively, the inner wall of the connecting body 20 may slide against the outer wall of the fixing part 30.

[0053] In specific embodiments of this application, such as Figure 5 and Figure 9 As shown, the connector 20 includes a main part 21, a "V"-shaped reinforcing plate 22 fixed inside the main part 21, a fixing plate 23 fixed to the bottom of the main part 21 (facing the fixing part 30) by bolts and nuts, and a baffle 24 fixed to the bottom side of the main part 21 by the fixing plate 23. Figure 9 As shown, the main part 21 is formed as a cover structure with open top, bottom and sides. The shape of the reinforcing plate 22 is adapted to the shape inside the main part 21. The reinforcing plate 22 is used to increase the strength of the connecting body 20 and prevent the main part 21 from deforming. A rotation gap is formed between the side of the main part 21 with the baffle 24 and the fixing part 30. The side without the baffle 24 is located inside the cavity of the fixing part 30 (inside the right-angled triangular prism formed by the three side beams 31 of the fixing part 30, which will be described later) and can slide relative to the inner wall of the cavity of the fixing part 30 (the inner wall of the side beams 31). The baffle 24 is formed as a silicone soft plate to block the rotation gap and prevent impurities from entering the cover formed by the main part 21 during operation, thereby preventing impurities from entering the operating parts of crop harvesting machinery, such as the header of a corn harvester.

[0054] Reference Figure 1 , Figure 3 , Figure 4 as well as Figures 10 to 13 The adjustment component 40 also includes a first locking component 46, and the connection position includes multiple connection holes. Different connection holes 421 can be adjusted to be connected to the fixing holes on the fixing part 30 through the first locking component 46.

[0055] Multiple connecting holes 421 are spaced apart along the extending direction of the connecting positioning member 42. When the width needs to be adjusted, the first locking member 46 is removed from the connecting positioning member 42, and the second locking member 44 is loosened at the same time. The adjusting assembly 40 is rotated with the axis of the first locking hole 4321 of the adapter 43 as the pivot until the appropriate connecting hole 421 on the connecting positioning member 42 is coaxial with the fixing hole of the fixing part 30. Then the first locking member 46 is installed on the connecting hole 421 of the connecting positioning member 42 and the fixing hole of the fixing part 30 to fix the connecting positioning member 42 and the fixing part 30 relative to each other. At the same time, the second locking member 44 is tightened to strengthen the connection between the adjusting assembly 40 and the fixing part 30, ensuring the structural strength and stability of the divider during use.

[0056] The number of connecting holes 421 can be determined according to actual needs, for example, it can be three. The connecting holes 421 are preferably evenly spaced on the connecting positioning member 42. The smaller the distance between adjacent connecting holes 421, the higher the adjustment accuracy of the width. The first locking member 46 can be a combination of bolts and nuts.

[0057] Continue to refer to Figure 1 , Figure 3 , Figure 4 as well as Figures 10 to 13 The connecting positioning member 42 is formed into multiple arc-shaped connecting positioning plates, with at least two connecting positioning plates arranged on opposite sides of the fixing part 30, and the connecting holes 421 on the two connecting positioning plates are arranged one-to-one.

[0058] Multiple connecting holes 421 spaced apart along the arc-shaped extension direction of the connecting positioning plates form connecting positions. Two connecting positioning plates are fixedly connected to the fixing part 30 by a first locking member 46. The two connecting positioning plates can increase the connection stability between the adjusting assembly 40 and the fixing part 30. The extension direction of the connecting positioning plates is the rotation direction of the adjusting assembly 40 relative to the fixing part 30 when adjusting the width.

[0059] The second aspect of this utility model provides a crop harvesting machine, including the above-mentioned divider.

[0060] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto.
