Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a header assembly and a combine harvester. Background Technology
[0002] As the core equipment of modern agricultural mechanization, the combine harvester's core function is to achieve efficient harvesting of crops by integrating harvesting, threshing, and cleaning processes. Different crops have different morphological characteristics and harvesting process requirements, so combine harvesters need to be equipped with dedicated headers to adapt to different crops. Therefore, during the harvest season, users need to frequently change different headers to harvest different crops.
[0003] Currently, the header of a combine harvester is generally installed by bolt fastening or pin positioning. This method requires aligning, inserting, and pre-tightening multiple mounting holes (bolt holes or pin holes) one by one. This is not only cumbersome, but also prone to problems during installation. Sometimes, due to improper positioning of the mounting holes, machining errors of parts, or deformation of structural components at the connection of the mounting holes, it is necessary to use pry bars, hammers, or other auxiliary means to forcibly insert or remove the bolts or pins, making disassembly and assembly quite laborious. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies, this utility model provides a header assembly and a combine harvester, aiming to solve the technical problem of cumbersome disassembly and assembly of the header on the combine harvester.
[0005] To achieve the above objectives, this utility model provides a header assembly, which includes a header mounting bracket and a first locking component. The header mounting bracket has an insertion cavity for inserting a first connecting portion of the harvester body. The first locking component is movably disposed within the insertion cavity and can move into and out of the insertion installation path. The insertion installation path is the installation movement path when the first connecting portion is inserted into the insertion cavity. The first locking component is used to limit and abut the inserted first connecting portion in the rear direction, locking the first connecting portion within the insertion cavity.
[0006] In this embodiment, the first locking assembly includes an adjusting shaft and a locking block. The adjusting shaft is rotatably mounted in the insertion cavity and offset from the insertion installation path. The locking block is disposed on the adjusting shaft and is used to abut or avoid the back side of the first connecting part. The locking block can be moved in or out of the insertion installation path by rotating the adjusting shaft.
[0007] In this embodiment, the cutter mounting bracket includes a first mounting seat with a insertion cavity. The first mounting seat includes a mounting stop disposed in the insertion cavity. The mounting stop and the locking block are spaced apart in the insertion direction. The mounting stop is located on the insertion installation path of the first mounting seat entering and exiting the insertion cavity and is used to limit and hold the first connecting part at the front side in the insertion direction.
[0008] In this embodiment, the first locking component further includes an anti-rotation locking member, which is used to lock the adjusting shaft to prevent rotation.
[0009] In this embodiment, the header mounting bracket further includes a second mounting seat, which is arranged vertically and vertically spaced from the first mounting seat. The header assembly also includes a second locking component, which is used to connect and lock the second mounting seat to the second connecting part of the harvester body.
[0010] To achieve the above objectives, the present invention also provides a combine harvester, wherein the combine harvester includes a harvester body and a header assembly as described above. The harvester body is provided with a first connecting part, which is inserted into the insertion cavity of the header assembly. The peripheral wall of the insertion cavity and a first locking component jointly limit the first connecting part to lock it in the insertion cavity.
[0011] In this embodiment, the cutter mounting bracket includes a mounting stop disposed in the insertion cavity. The first connecting part is provided with a locking block for inserting into the insertion cavity and engaging with the mounting stop for limiting and supporting. The locking block is provided with a locking groove on the back side in the insertion direction for engaging with the first locking component.
[0012] In this embodiment, the locking block includes a bottom wall and a side wall. The bottom wall limits the bottom of the hook stop in the insertion direction, and the side wall abuts the side of the hook stop and is located between the hook stop and the first locking component. The locking groove is provided on the side of the side wall facing away from the hook stop.
[0013] In this embodiment, the harvester body also includes a vertically arranged lifting drive component, and a first connecting part is disposed on the lifting movable end of the lifting drive component. The lifting drive component is used to adjust the height of the first connecting part.
[0014] In this embodiment, the header mounting bracket is provided with a first pin hole, which is spaced vertically from the insertion cavity. The harvester body is provided with a second connecting part, which is provided with a second pin hole for engaging with the pin of the first pin hole. At least one of the first pin hole and the second pin hole is a waist-shaped hole, and the waist length direction of the waist-shaped hole is parallel to the vertical direction.
[0015] In this embodiment, at least two insertion cavities are formed on the header mounting frame. The at least two insertion cavities are arranged at intervals along the lateral direction of the header mounting frame. The number of lifting drive components on the harvester body is at least two. The at least two lifting drive components are arranged one-to-one with the at least two insertion cavities that are arranged at intervals along the lateral direction. Each lifting drive component has a first connecting part on its lifting movable end.
[0016] Through the above technical solution, the header assembly provided by this utility model embodiment has the following beneficial effects:
[0017] In this embodiment, the header assembly only needs to control the first locking component to move into and out of the insertion and installation path to achieve locking and unlocking between the header mounting bracket and the harvester body. During the locking and unlocking process of the header mounting bracket, there is no need for shaft hole alignment and positioning, bolt insertion and removal, etc., which greatly reduces the disassembly and assembly steps. In addition, the locking method of the header assembly in this embodiment has low requirements for the positional accuracy of the first locking component. Even if the first locking component has large part machining errors or large deformation of the structural parts near the first locking component, as long as the first connecting part is inserted into the insertion cavity, the first locking component can move to the back side of the first connecting part to achieve locking of the first connecting part. The frequency of need for auxiliary tools such as pry bars and hammers during disassembly and assembly is low, making disassembly and assembly more labor-saving.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0028] The cutting platform assembly of this utility model is described below with reference to the accompanying drawings.
[0029] This utility model provides a header assembly, such as Figure 1 , Figure 2 and Figure 4 As shown, the cutter assembly in this embodiment includes a cutter body, a cutter mounting bracket 1, and a first locking component 2.
[0030] The header body is fixedly connected to the header mounting bracket 1, which is used to hang on the harvester body 3 of the combine harvester. The header mounting bracket 1 has an insertion cavity 11a for the first connecting part 31 of the harvester body 3 to be inserted.
[0031] The first locking component 2 is movably disposed within the insertion cavity 11a and can move in and out of the insertion installation path. The insertion installation path is the installation movement path when the first connecting part 31 is inserted into the insertion cavity 11a. The first locking component 2 is used to limit and abut the inserted first connecting part 31 in the rear direction to lock the first connecting part 31 within the insertion cavity 11a.
[0032] Locking the first connecting part 31 in the insertion cavity 11a means that the first connecting part 31 cannot be disengaged from the insertion cavity 11a due to the combined action of the first locking component 2 and the peripheral wall of the insertion cavity 11a.
[0033] In this embodiment, when the header assembly is attached, the first connecting part 31 of the harvester body 3 is first aligned with the insertion cavity 11a of the header attachment frame 1 along the insertion direction. Then, the harvester body 3 or the header assembly is moved along the insertion direction so that the first connecting part 31 is inserted into the insertion cavity 11a. After the first connecting part 31 is inserted into the insertion cavity 11a, the first locking component 2 is moved into the insertion installation path, so that the first locking component 2 limits and abuts against the back side of the first connecting part 31 in the insertion direction, thereby locking and fixing the first connecting part 31 in the insertion cavity 11a.
[0034] Similarly, when the cutting platform assembly needs to be removed, simply move the first locking component 2 out of the insertion mounting path, and then move the first connecting part 31 out in the opposite direction of the insertion direction.
[0035] In summary, in this embodiment, the header assembly only needs to control the first locking component 2 to move into and out of the insertion and installation path to achieve locking and unlocking between the header mounting bracket 1 and the harvester body 3. During the locking and unlocking process of the header mounting bracket 1, there is no need to perform steps such as shaft hole alignment and positioning, bolt insertion and removal, which greatly reduces the disassembly and assembly steps. In addition, the locking method of the header assembly in this embodiment has low requirements for the positional accuracy of the first locking component 2. Even if the first locking component 2 has large part machining errors or large deformation of the structural parts near the first locking component 2, as long as the first connecting part 31 is inserted into the insertion cavity 11a, the first locking component 2 can move to the back side of the first connecting part 31 to achieve locking of the first connecting part 31. The disassembly and assembly process requires less frequency of auxiliary tools such as pry bars and hammers, making disassembly and assembly more labor-saving.
[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the cutter head bracket 1 includes a bracket body composed of several crossbeams, longitudinal beams, and reinforcing beams, and a first bracket seat 11 disposed on the bracket body. An insertion cavity 11a is formed on the first bracket seat 11 and is jointly enclosed by the first bracket seat 11 and the bracket body. To limit the insertion depth of the first connecting part 31 within the insertion cavity 11a, the first bracket seat 11 may include a bracket stop 111. The bracket stop 111 is disposed within the insertion cavity 11a and located on the insertion path of the first bracket seat 11 entering and exiting the insertion cavity 11a. When the first connecting part 31 is inserted into the insertion cavity 11a to a set depth, the bracket stop 111 abuts against the front side of the first connecting part 31 in the insertion direction. Through the cooperation of the first locking component 2 and the bracket stop 111, the degree of freedom of the first connecting part 31 in the insertion direction can be limited.
[0037] In this embodiment, the first locking component 2 can have many structural forms, such as Figure 2 , Figure 3 and Figure 4 As shown, the first locking assembly 2 may include an adjusting shaft 21 and a locking block 22. The adjusting shaft 21 is rotatably mounted in the insertion cavity 11a and offset from the insertion path. The locking block 22 is disposed on the adjusting shaft 21. By rotating the adjusting shaft 21, the locking block 22 can move in or out of the insertion path to abut or avoid the back side of the first connecting part. With the above configuration, simply rotating the adjusting shaft 21 to the corresponding angle can lock or unlock the header mounting bracket 1 on the harvester body 3.
[0038] Alternatively, the first locking assembly 2 may also include a telescopic cylinder and a locking block 22, which can be extended and retracted in a direction perpendicular to the insertion direction by means of a telescopic rod, thus driving the locking block 22 to move into or out of the insertion installation path.
[0039] Alternatively, the first locking component 2 may include a swing rod and a locking block 22. By driving the swing rod to rotate in a direction perpendicular to the insertion direction, the locking block 22 can also be driven to move into or out of the insertion installation path.
[0040] like Figure 4 As shown, in this embodiment, when the locking block 22 moves into the insertion path, it is necessary to ensure that the locking block 22 and the hook stop 111 are spaced apart in the insertion direction. This ensures that the hook stop 111 abuts against the front side of the first connecting part in the insertion direction, and the locking block abuts against the back side of the first connecting part in the insertion direction.
[0041] like Figure 3 and Figure 4 As shown, in this embodiment, the first locking component 2 may further include a rotation-stopping locking member 23, which is used to lock the adjusting shaft 21 to prevent rotation.
[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the anti-rotation locking component can be a locking plate fixedly installed on the adjusting shaft 21. When the adjusting shaft 21 rotates to a preset angle, the locking plate can be connected to the first mounting base 11 by using the anti-rotation locking pin 25 or the anti-rotation locking bolt, thereby locking the adjusting shaft 21. Of course, the anti-rotation locking component 23 can also be a limiting block provided on the adjusting shaft 21. When the adjusting shaft 21 rotates to a set angle, the limiting block contacts the limiting structure on the first mounting base 11, thereby preventing the adjusting shaft 21 from rotating.
[0043] It is understood that the anti-rotation locking element 23 can be configured to lock the adjusting shaft 21 at multiple or a single position. In other words, the aforementioned preset angle can be one or multiple.
[0044] like Figure 3As shown, in this embodiment, the first locking component 2 may also include a handle 24, which allows the operator to easily drive the adjusting shaft 21 to rotate.
[0045] In this embodiment, in order to lock the first connecting portion 31 within the insertion cavity 11a, the first mounting base 11 may further include a plurality of cavity sidewalls for surrounding the insertion cavity 11a. For example... Figure 3 and Figure 4 As shown, when the insertion direction is longitudinal or vertical, the first mounting base 11 may also include a first cavity sidewall 112 and a second cavity sidewall 113 arranged laterally. The first cavity sidewall 112 and the second cavity sidewall 113 can restrict the degree of freedom of the first connecting part 31 in the lateral direction.
[0046] To achieve the above objectives, this utility model also provides a combine harvester, wherein the combine harvester includes a harvester body 3 and a header assembly as described above. The harvester body 3 is provided with a first connecting part 31. When the header assembly is installed and locked on the harvester body 3, the first connecting part 31 is inserted into the insertion cavity 11a of the header assembly. The peripheral wall of the insertion cavity 11a and the first locking component 2 jointly limit the first connecting part to be locked in the insertion cavity 11a.
[0047] After the first connecting part 31 is inserted into the insertion cavity 11a, the first locking component 2 is simply moved into the insertion installation path, so that the first locking component 2 and the hook stop 111 limit and hold the first connecting part 31 on both sides in the insertion direction. By the joint limitation of the peripheral wall of the insertion cavity 11a, the hook stop 111, and the first locking component 2, the first connecting part 31 can be locked and fixed in the insertion cavity 11a. When the header assembly needs to be unlocked, the first locking component 2 is simply moved out of the insertion installation path. In this embodiment, the combine harvester is simple and labor-saving to lock or unlock the header assembly, and disassembly and assembly are quick.
[0048] like Figure 4 and Figure 5 As shown, in this embodiment, the first connecting part 31 is provided with a locking block 311 for insertion into the insertion cavity 11a and for limiting and abutting against the hook stop 111. The locking block 311 has a locking groove 311c on its back side in the insertion direction for engaging with the first locking component 2. When the first connecting part 31 is inserted into the insertion cavity 11a, the locking block 311 abuts against the hook stop 111 on its front side in the insertion direction. By moving the first locking component 2 into the locking groove 311c on the back side, the locking groove 311c can limit the first connecting part 31 in the insertion direction and also limit the first connecting part 31 in the groove width direction.
[0049] like Figure 4 and Figure 5As shown, in this embodiment, the locking groove 311c is a stepped groove, meaning that the bottom wall of the locking groove has several steps. When the first locking component 2 moves within the locking groove 311c, it first engages with the first step, then the second, and then the third. In adjacent steps, the depth of the upper step is greater than the depth of the lower step; that is, the second step is less than the depth of the first step, and the third step is less than the depth of the second step. By engaging with different numbers of steps within the locking groove 311c, the tightness of the locking of the locking block 311 by the first locking component 2 can be adjusted.
[0050] In addition, the side wall of the step adjacent to the next step in each step is preferably an inclined side wall with a certain angle. When the first locking component 2 moves to the next step, the inclined side wall can guide the movement of the first locking component 2. At the same time, the inclined side wall can also facilitate the stepless adjustment of the locking gap. That is, for any locking gap, the first locking component 2 can be used in conjunction with the appropriate inclined side wall to achieve a firm locking of the locking block 311.
[0051] like Figure 4 and Figure 5 As shown, in this embodiment, the locking block 311 has a bottom wall 311a and a side wall 311b on its front side in the insertion direction. When the first connecting part extends into the insertion cavity, the bottom wall 311a will limit and abut against the bottom of the hook stop 111 in the insertion direction, and the side wall 311b will abut against the side of the hook stop 111. The side wall 311b is located between the first locking assembly 2 and the hook stop 111. The locking groove 311c is provided on the side of the side wall 311b facing away from the hook stop 111.
[0052] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, taking the insertion direction as vertical as an example, the hanging stop 111 and the first locking component 2 are vertically spaced. Since the first locking component 2 needs to avoid the insertion installation path, the first locking component 2 can be set behind the hanging stop 111 in the longitudinal direction. The locking block 311 includes a bottom wall 311a and a side wall 311b. When the locking block 311 is inserted into the insertion cavity 11a, the bottom wall 311a will limit the bottom of the hanging stop 111, and the side wall 311b will limit the side of the hanging stop 111. The abutment position of the first locking component 2 is set on the side of the side wall 311b facing away from the hanging stop 111. Only one locking block 311 is needed to limit the first connecting part 31 in the vertical and longitudinal directions.
[0053] It should be noted that the vertical, horizontal, and up / down directions are all mutually perpendicular.
[0054] like Figure 4 As shown, in this embodiment, the harvester body 3 also includes a vertically arranged lifting drive component 32. A first connecting part 31 is disposed on the lifting movable end of the lifting drive component 32, and the lifting drive component 32 is used to adjust the height of the first connecting part. By setting the lifting drive component 32, it is convenient for the first connecting part 31 on the harvester body 3 to be plugged into and cooperate with header assemblies of different heights, solving the problem of inconsistent hanging node heights of different models of header assemblies and increasing assembly compatibility.
[0055] like Figure 1 As shown, in this embodiment, the main body of the mounting frame is provided with at least two first mounting seats 11, which are arranged laterally at intervals. Each first mounting seat 11 has an insertion cavity. The number of first connecting parts 31 and lifting drive members 32 on the harvester body 3 is at least two, and preferably, each of the at least two lifting drive members 32 corresponds to one of the at least two laterally spaced first mounting seats 11. Through multiple first mounting seats 11, the header mounting frame 1 can form a multi-point mounting pattern in the lateral direction, thereby increasing the stability of the header mounting frame 1. Furthermore, through the coordinated adjustment of multiple lifting drive members 32 in the lateral direction, the lateral horizontal posture of the first mounting seats 11 and the overall working height of the header assembly can be adjusted, allowing the header assembly to adapt to different terrains.
[0056] In this embodiment, the lifting drive component 32 can be a hydraulic cylinder, an electric cylinder, or the like.
[0057] like Figure 1 and Figure 4 As shown, in this embodiment, the header mounting bracket 1 further includes a second mounting seat 12, which is vertically spaced from the first mounting seat 11. The header assembly also includes a second locking component 4, which is used to connect and lock the second mounting seat 12 to the second connecting part 33 of the harvester body 3. Through the cooperation of the second mounting seat 12 and the first mounting seat 11, a pattern of vertical and horizontal mounting can be formed on the header mounting bracket 1.
[0058] The second locking component 4 can be a pin, bolt, etc. Taking a pin connection as an example, such as... Figure 1 and Figure 4 As shown, the second mounting base 12 is a shaft hole seat and the second mounting base 12 is provided with a first pin hole. The second connecting part 33 is provided with a second pin hole 33a for cooperating with the first pin hole pin. The first pin hole and the second pin hole 33a are connected by a pin to realize the connection and locking between the second mounting base 12 and the second connecting part 33 of the harvester body 3.
[0059] like Figure 4As shown, in this embodiment, in order to avoid the connection restriction of the second mounting bracket 12 affecting the adjustment function of the horizontal posture of the cutting table assembly, at least one of the first pin hole and the second pin hole 33a can be set as a waist-shaped hole, and the waist length direction of the waist-shaped hole needs to be parallel to the vertical direction.
[0060] In summary, the combine harvester in this embodiment optimizes the connection and locking method between the harvester body 3 and the header assembly. Instead of the existing pins or bolts, the first locking component 2 abuts against the back of the first connecting part, solving the problems of difficult header connection and cumbersome, laborious installation. Furthermore, by setting a lifting drive component 32 between the first connecting part and the harvester body, the problem of inconsistent connection point heights for different header assembly models is solved. The cooperation of multiple lifting drive components 32 also allows for adjustment of the header assembly's lateral horizontal posture, thus adapting to terrains with varying slopes.
