DETAILED DESCRIPTION
[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention but not to limit the scope of the present invention.
[0049] like Figures 1 to 17 As shown, an embodiment of the present invention provides a quickly detachable concave plate structure of a harvesting machine, comprising: a concave plate frame 1 and a plurality of concave plates 2, wherein the plurality of concave plates 2 are slidably mounted on the concave plate frame 1.
[0050] The beneficial effect of adopting the technical solution of the present invention is that the harvesting machinery can quickly disassemble the concave plate structure including the concave plate frame and multiple concave plates, which is faster and more convenient when replacing concave plates of different grid sizes. When replacing the concave plates, only small concave plates need to be disassembled and replaced to complete the task, and the operation is simple and convenient.
[0051] For easy disassembly, the harvesting machinery can quickly disassemble the concave plate structure can be composed of a concave plate frame and multiple small concave plates, when the small concave plate (concave plate) needs to be disassembled, the concave plate fixing mechanism is removed, at this time the concave plate (concave plate) is in an active state, and the small concave plate (concave plate) can be pulled out.
[0052] Figure 6 In the figure, the circular structure above the concave plate 2 can be the outer circle of the threshing drum.
[0053] like Figures 1 to 17 As shown, further, a concave plate fixing mechanism 3 is installed on the concave plate frame 1, and one side of the plurality of concave plates 2 is connected to the concave plate fixing mechanism 3.
[0054] The beneficial effect of adopting the above further technical solution is that when it is necessary to remove the small concave plate, the concave plate fixing mechanism 3 is removed. At this time, the concave plate is in an active state, and the small concave plate can be pulled out.
[0055] like Figures 1 to 17 As shown, further, one side of the plurality of concave plates 2 is respectively provided with a mounting hole 4 , and one side of the plurality of concave plates 2 is respectively connected to the concave plate fixing mechanism 3 through the mounting hole 4 .
[0056] The beneficial effect of adopting the above further technical solution is that the small concave plate is positioned at the correct position through the mounting hole.
[0057] like Figures 1 to 17 As shown, further, a plurality of positioning pins 5 are installed on the concave plate frame 1, and the other sides of the plurality of concave plates 2 are respectively connected to the plurality of positioning pins 5.
[0058] The beneficial effect of adopting the above further technical solution is that the positioning pins on the concave plate frame can position the small concave.
[0059] like Figures 1 to 17 As shown, further, the other sides of the plurality of concave plates 2 are respectively provided with positioning holes 6 adapted to the positioning pins 5 , and the other sides of the plurality of concave plates 2 are respectively connected to the plurality of positioning pins 5 through the positioning holes 6 .
[0060] The beneficial effect of adopting the above further technical solution is that the positioning hole cooperates with the positioning pin on the concave plate frame, and the positioning pin on the concave plate frame can position the small concave.
[0061] like Figures 1 to 17 As shown, further, a plurality of first support plates 7 for limiting the left and right positions of the concave plate are installed on the concave plate frame 1 , and the concave plate 2 is slidably installed between two adjacent first support plates 7 .
[0062] The beneficial effect of adopting the above further technical solution is that the provision of the first support plate facilitates the left and right positioning of each concave plate, prevents the concave plate from shaking left and right, and facilitates the alignment of the positioning pin and the positioning hole.
[0063] like Figures 1 to 17 As shown, further, a guide rail 8 is installed on the first support plate 7 , the height of the first support plate 7 is higher than the height of the guide rail 8 , and the concave plate 2 is slidably installed between two adjacent first support plates 7 through the guide rail 8 .
[0064] The beneficial effect of adopting the above further technical solution is that the guide rail can help the small concave plate move to the correct working position, which is convenient for installing and disassembling the concave plate.
[0065] A plurality of second support plates 13 may be mounted on the concave plate 2 . The second support plates 13 are provided with support plate sliding surfaces 14 . The support plate sliding surfaces 14 are slidably connected to the guide rails 8 .
[0066] The guide rail 8 may be arranged parallel to the first support plate 7 , and the guide rail 8 is connected to the first support plate 7 .
[0067] Specifically, a guide rail 8 is installed on the inner side of the first support plate 7 located at both ends of the concave plate frame 1. Guide rails 8 are installed on both sides of the first support plate 7 located in the middle of the concave plate frame 1. The first support plate 7 and the guide rail 8 are both arc-shaped plate structures, and the height of the first support plate 7 is higher than the height of the guide rail 8. When the concave plate slides along the guide rail 8, since the height of the first support plate 7 is higher than the height of the guide rail 8, two adjacent first support plates 7 limit the left and right sides of the concave plate to prevent the concave plate from shaking left and right, so as to facilitate the alignment of the positioning pin and the positioning hole.
[0068] The concave plate frame can be composed of a small concave plate fixing mechanism (concave plate fixing mechanism), a guide rail, a first support plate and other structures, and the guide rail can help the small concave plate (concave plate 2) move to the correct working position. Among them, the concave plate fixing mechanism can include: a mounting seat and a bolt, the mounting seat is connected to the mounting hole through the bolt, and the concave plate fixing mechanism is disassembled by removing the bolts of the concave plate fixing mechanism.
[0069] An embodiment of the present invention provides a harvesting machine with a quickly detachable concave plate structure, which can be an easily detachable concave plate, making it faster and more convenient to replace concave plates of different grid sizes. When replacing the concave plate, only a small concave plate (concave plate) needs to be disassembled and replaced to complete the task.
[0070] By sliding the support plate sliding surface 14 on the guide rail, the small concave plate (concave plate 2) moves to the correct position, the positioning hole cooperates with the positioning pin on the concave plate frame to reach the specified position, and the small concave plate (concave plate 2) is positioned in the correct position through the installation hole and other related structures.
[0071] If the small concave plate (concave plate 2) needs to be put back into the concave plate frame, the small concave plate (concave plate 2) is placed on the guide rail of the concave plate frame, and the small concave plate (concave plate 2) can be pushed to the correct working position, and then the small concave plate (concave plate 2) is fixed by the concave plate fixing mechanism. The positioning pins on the concave plate frame can position the small concave plate (concave plate 2). Due to the geometric relationship between the concave plate frame and the small concave plate (concave plate 2), the concave plate frame can also play a certain positioning role and withstand a certain force. Among them, the concave plate, the concave plate frame, the guide rail and the first support plate are all arc-shaped.
[0072] like Figure 20 to Figure 22 As shown, in addition, the present invention also provides a quickly detachable concave plate assembly of a harvesting machinery, including: a fixed concave plate assembly 9 and a movable concave plate assembly 10, wherein the fixed concave plate assembly 9 and the movable concave plate assembly 10 are both installed with a quickly detachable concave plate structure of a harvesting machinery as described in any one of the above items, and the fixed concave plate assembly 9 is hinged to the movable concave plate assembly 10.
[0073] The beneficial effect of adopting the technical solution of the present invention is that the harvesting machinery can quickly disassemble the concave plate structure including the concave plate frame and multiple concave plates, which is faster and more convenient when replacing concave plates of different grid sizes. When replacing the concave plates, only small concave plates need to be disassembled and replaced to complete the task, and the operation is simple and convenient.
[0074] like Figure 20 to Figure 22 As shown, further, a plurality of hinge points 11 are installed on both the fixed concave plate assembly 9 and the movable concave plate assembly 10 , and the hinge points of the fixed concave plate assembly 9 and the movable concave plate assembly 10 are hinged via a pin 12 .
[0075] The beneficial effect of adopting the above further technical solution is that the concave plate assembly is composed of a fixed concave plate assembly and a movable concave plate assembly, which are connected together by a pin in the middle.
[0076] Preferably, a conical feeding plate 15 is installed on the movable concave plate assembly 10. The conical feeding plate can guide the material and eliminate the phenomenon of blockage caused by poor material flow.
[0077] Furthermore, the front end of the movable concave plate assembly 10 is shorter than that of the fixed concave plate assembly 9, and the conical feeding plate 15 is arranged at the short position. After the conical feeding plate 15 is added, the movable concave plate assembly 10 is basically the same length as the fixed concave plate assembly 9.
[0078] The concave plate assembly (harvester quick-detachable concave plate assembly) is composed of a fixed concave plate assembly and a movable concave plate assembly, which are connected together by a pin shaft and a movable pin, etc. Among them, the hinge point can be a sleeve structure.
[0079] like Figures 9 to 19 As shown, since the embodiment of the present invention needs to adjust the concave plate gap by changing the position of the movable concave plate (movable concave plate assembly) to change the threshing capacity of the harvesting machine, the change in the position of the movable concave plate will cause the material to flow poorly when entering the movable concave plate, causing blockage, so a conical feeding plate 15 is provided. The conical feeding plate 15 can be installed on the concave plate frame of the movable concave plate assembly.
[0080] The front end of the movable concave plate frame (concave plate frame) is provided with a conical feeding plate 15, which can guide the material and eliminate the phenomenon of blockage caused by poor material flow.
[0081] 1. The concave plate (the concave plate structure that can be quickly disassembled by the harvesting machinery) is composed of a concave plate frame and a plurality of small concave plates (concave plates 2).
[0082] 2. The small concave plate (concave plate 2) slides on the slide rail (guide rail 8) through the support plate sliding surface 14 and can slide to the correct working position. The slide rail (guide rail 8) assists the small concave plate (concave plate 2) to slide to a fixed position.
[0083] 3. After the small concave plate (concave plate 2) is moved to the correct installation position, one end thereof is fixed by the concave plate fixing mechanism, and the other end is positioned by the geometric relationship of the concave plate frame and the positioning pin.
[0084] 4. A conical feeding plate 15 is arranged at the front end of the movable concave plate frame (concave plate frame), which can guide the material and eliminate the phenomenon of blockage caused by poor material flow.
[0085] It is quicker and more convenient to replace concave plates of different grid sizes. When replacing the concave plates, it is only necessary to dismantle and replace a small concave plate (concave plate 2) to complete the work. The operation is simple and convenient.
[0086] It should be noted that the positioning pin of the fixed concave plate assembly 9 is arranged away from the pin shaft 12, and the positioning pin of the movable concave plate assembly 10 is arranged adjacent to the pin shaft 12. When the concave plate is installed on the fixed concave plate assembly 9, the concave plate is pushed into the fixed concave plate assembly 9 from the position of the fixed concave plate assembly 9 adjacent to the pin shaft 12. When the concave plate is installed on the movable concave plate assembly 10, the concave plate is pushed into the movable concave plate assembly 10 from the position of the movable concave plate assembly 10 away from the pin shaft 12.
[0087] In addition, the present invention also provides a harvesting machine, comprising a harvesting machine quick-detachable concave plate assembly as described in any one of the above.
[0088] The beneficial effect of adopting the technical solution of the present invention is that the harvesting machinery can quickly disassemble the concave plate structure including the concave plate frame and multiple concave plates, which is faster and more convenient when replacing concave plates of different grid sizes. When replacing the concave plates, only small concave plates need to be disassembled and replaced to complete the task, and the operation is simple and convenient.
[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
