[0054] The beneficial effect of adopting the above-mentioned further technical solution is that when it is necessary to disassemble the small concave plate, the concave plate fixing mechanism 3 can be disassembled. 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, each of the plurality of concave plates 2 has a mounting hole 4 on one side, and each of the plurality of concave plates 2 is connected to the concave plate fixing mechanism 3 through the mounting hole 4.

[0056] The beneficial effect of adopting the above-mentioned further technical solution is that the small concave plate is positioned in the correct position through the mounting hole.

[0057] likeFigures 1 to 17 As shown in the figure, further, a plurality of positioning pins 5 are installed on the recessed plate frame 1, and the other sides of the plurality of recessed plates 2 are respectively connected with the plurality of positioning pins 5.

[0058] The beneficial effect of the above further technical solution is that the positioning pins on the recessed plate frame can position the small recesses.

[0059] As shown in the figure, Figures 1 to 17 Further, the other sides of the plurality of recessed plates 2 are respectively provided with positioning holes 6 matched with the positioning pins 5, and the other sides of the plurality of recessed plates 2 are respectively connected with the plurality of positioning pins 5 through the positioning holes 6.

[0060] The beneficial effect of the above further technical solution is that the positioning holes cooperate with the positioning pins on the recessed plate frame, and the positioning pins on the recessed plate frame can position the small recesses.

[0061] As shown in the figure, Figures 1 to 17 Further, a plurality of first support plates 7 for limiting the recessed plates left and right are installed on the recessed plate frame 1, and the recessed plates 2 are slidingly installed between adjacent two first support plates 7.

[0062] The beneficial effect of the above further technical solution is that the first support plates are provided to facilitate the left and right limiting of each recessed plate, prevent the recessed plates from shaking left and right, and facilitate the alignment of the positioning pins and the positioning holes.

[0063] As shown in the figure, Figures 1 to 17 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 recessed plates 2 are slidingly installed between adjacent two first support plates 7 through the guide rail 8.

[0064] The beneficial effect of the above further technical solution is that the guide rail can help the small recessed plates move to the correct working position, facilitating the installation and disassembly of the recessed plates.

[0065] Among them, a plurality of second support plates 13 can be installed on the recessed plates 2, the second support plates 13 are provided with support plate sliding surfaces 14, and the support plate sliding surfaces 14 are slidingly connected with the guide rails 8.

[0066] The guide rail 8 can be arranged in parallel with the first support plate 7, and the guide rail 8 is connected with the first support plate 7.

[0067] Specifically, the inner side of the first support plate 7 at both ends of the concave plate frame 1 is respectively provided with a guide rail 8.

When the concave plate slides along the guide rail 8, because the height of the first support plate 7 is higher than the height of the guide rail 8, the two adjacent first support plates 7 limit the left and right sides of the concave plate, prevent the concave plate from shaking left and right, and 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 the like. The guide rail can help the small concave plate (concave plate 2) to move to the correct working position. The concave plate fixing mechanism can include a mounting seat and a bolt. The mounting seat is connected with the mounting hole through the bolt. The concave plate fixing mechanism can be disassembled by disassembling the bolt of the concave plate fixing mechanism.

[0069] The concave plate structure provided by the embodiment of the utility model can be quickly disassembled, and the concave plate is convenient to disassemble. When different grid size concave plates are replaced, it is more convenient and fast. When the concave plate is replaced, only the small concave plate (concave plate) needs to be disassembled and replaced, and the work can be completed.

[0070] The small concave plate (concave plate 2) is moved to the correct position by the sliding of the support plate sliding surface 14 on the guide rail. The positioning hole is matched with the positioning pin on the concave plate frame, reaches the specified position, and the small concave plate (concave plate 2) is positioned in the correct position through the mounting hole and other related structures.

[0071] If the small concave plate (concave plate 2) needs to be put back to the concave plate frame, the small concave plate (concave plate 2) is put on the guide rail of the concave plate frame, the small concave plate (concave plate 2) is 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 pin 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 bear a certain force. The concave plate, the concave plate frame, the guide rail and the first support plate are all arc-shaped.

[0072] As shown in FIG. 1, Figures 20 to 22 In addition, the utility model also provides a kind of concave plate assembly of quick disassembly of harvesting machinery, including: fixed concave plate assembly 9 and movable concave plate assembly 10, fixed concave plate assembly 9 and movable concave plate assembly 10 are all equipped with the quick disassembly of harvesting machinery of any one described in the kind of concave plate structure, fixed concave plate assembly 9 and movable concave plate assembly 10 are hinged.

[0073] The beneficial effects of adopting the technical solution of this utility model are: the harvesting machinery can quickly disassemble the concave plate structure, which consists of a concave plate frame and multiple concave plates. It is quicker and more convenient to replace concave plates of different grid sizes. When replacing concave plates, only a small piece of concave plate needs to be disassembled and replaced to complete the work. The operation is simple and convenient.

[0074] like Figures 20 to 22 As shown, both the fixed concave plate assembly 9 and the movable concave plate assembly 10 are equipped with multiple hinge points 11, and the hinge points of the fixed concave plate assembly 9 and the hinge points of the movable concave plate assembly 10 are hinged by pins 12.

[0075] The beneficial effect of adopting the above-mentioned further technical solution is that the concave plate assembly consists of a fixed concave plate assembly and a movable concave plate assembly, which are connected together by a pin.

[0076] Preferably, a conical feed plate 15 is installed on the movable concave plate assembly 10. The conical feed 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 tapered feed plate 15 is provided at the short section. After the tapered feed 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 (a quick-release concave plate assembly for harvesting machinery) consists of a fixed concave plate assembly and a movable concave plate assembly, connected together by pins and movable pins. The hinge point can be a sleeve structure.

[0079] like Figures 9 to 19 As shown, since this embodiment of the invention requires adjusting the gap between the movable concave plates by changing the position of the movable concave plate (movable concave plate assembly), thereby changing the threshing capacity of the harvesting machinery, the change in the position of the movable concave plate will cause poor flow and blockage when the material enters the movable concave plate. Therefore, a conical feed plate 15 is provided. The conical feed plate 15 can be installed on the concave plate frame of the movable concave plate assembly.

[0080] The front end of the movable concave frame (concave frame) is equipped with a conical feed plate 15, which can guide the material and eliminate the phenomenon of blockage caused by poor material flow.

[0082] 2. The small concave plate (concave plate 2) slides on the slide rail (guide rail 8) through the sliding surface 14 of the support plate, 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 the fixed position.

[0083] 3. After the small concave plate (concave plate 2) is moved to the correct installation position, one end 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. The front end of the movable concave plate frame (concave plate frame) is provided with a tapered feeding plate 15, which can guide the material and eliminate the phenomenon of blockage caused by poor material flow.

[0085] When replacing concave plates of different grid sizes, it is more convenient to only disassemble and replace the small concave plate (concave plate 2) to complete the work, which is simple and convenient to operate.

[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 installing the concave plate on the fixed concave plate assembly 9, the concave plate is pushed into the fixed concave plate assembly 9 from the position adjacent to the pin shaft 12 of the fixed concave plate assembly 9. When installing the concave plate on the movable concave plate assembly 10, the concave plate is pushed into the movable concave plate assembly 10 from the position away from the pin shaft 12 of the movable concave plate assembly 10.

[0087] In addition, the utility model also provides a kind of harvesting machinery, including the quick detachable concave plate assembly of any one of the above described harvesting machinery.

[0088] The beneficial effects of the technical scheme of the utility model are: the quick detachable concave plate structure of harvesting machinery includes concave plate frame and multiple concave plates, which is more convenient when replacing concave plates of different grid sizes, and only needs to disassemble and replace small concave plates to complete the work, which is simple and convenient to operate.
