[0055] Combine the following Figure 1-Figure 9 A pull-out multi-section concave plate harvester provided in the present application is described in detail.
[0056] In this embodiment, a pull-out multi-section concave plate harvester is provided; the pull-out multi-section concave plate harvester comprises a concave plate component and a frame component.
[0057] Specifically, a plurality of concave plate members are provided, and the plurality of concave plate members are arranged in sequence along the first direction 3, and adjacent concave plate members are detachably connected by connecting members; Figure 1 As shown, the structure of four concave plate members is shown, and the four concave plate members are respectively a first concave plate member 1, a second concave plate member 26, a third concave plate member 27 and a fourth concave plate member 28. The first concave plate member 1, the second concave plate member 26, the third concave plate member 27 and the fourth concave plate member 28 are arranged in sequence along a first direction 3 to form a large concave plate member, wherein the first direction 3 refers to the extension direction of the frame member. Figure 4 Shown in.
[0058] Specifically, adjacent concave plate components are detachably connected by connecting components, that is, two adjacent concave plate components can be detached.
[0059] Specifically, the frame member is provided with an installation space 5, and the concave plate member is slidably arranged in the installation space 5, so that the concave plate member can be detachable from the frame member.
[0060] In the actual installation process, the following methods can be adopted: (1) the first concave plate member 1 is set on the frame member in a sliding manner; (2) the second concave plate member 26 is set on the frame member in a sliding manner, and the first concave plate member 1 and the second concave plate member 26 are connected together by a connecting member at the connection point; (3) the installation method of the third concave plate member 27 and the fourth concave plate member 28 is the same as the first concave plate member 1 and the second concave plate member 26, and will not be explained.
[0061] Assuming that the third concave plate member 27 is blocked, it is only necessary to release the connection between the fourth concave plate member 28 and the third concave plate member 27 and the connection between the third concave plate member 27 and the second concave plate member 26, and slide the third concave plate member 27 from the frame member to replace it with a new one. There is no need to perform any operation on the first concave plate member 1. The entire operation is simple and easy to disassemble.
[0062] In addition, when it is necessary to clean a certain concave plate component, the operating steps are the same as described above and will not be repeated; in addition, compared with the structure in the prior art that fixes the concave plate component to the frame component in a fixed manner, the concave plate component in the present application is detachably connected to the frame component, which is convenient for replacing the concave plate component; compared with the prior art that the concave plate component is an integral part and can slide down from the frame component, the concave plate component in the present application is a split structure, and there is no need to take all the concave plate components out of the frame component, so disassembly, cleaning and maintenance are more targeted, saving time and effort, and simple to operate.
[0063] In this embodiment, combined Figure 2 As shown, the recessed plate component includes a connecting plate 6 , ribs 7 and a slide rail 8 .
[0064] Specifically, two connecting plates 6 are provided, and the two connecting plates 6 are arranged at intervals along the second direction 9 so that a connecting space 10 is formed between the two connecting plates 6; the second direction 9 here refers to the width direction of the frame, the second direction 9 is perpendicular to the first direction 3, and the connecting plates 6 extend along the first direction 3.
[0065] Specifically, the ribs 7 are arc-shaped and a plurality of ribs 7 are provided, and the plurality of ribs 7 are arranged in the connecting space 10 at intervals along the first direction 3; in addition, the two ends of the ribs 7 are respectively welded to the two connecting plates 6; further, gaps are formed between the plurality of ribs 7, and the gaps can be used to screen melon seeds.
[0066] Specifically, the slide rail 8 is connected to a side of the connecting plate 6 away from the connecting space 10 and extends along the first direction 3 , that is, the slide rail 8 is arranged at the ends of the two connecting plates 6 away from each other.
[0067] In summary, the concave plate component has a slide rail 8 extending along the first direction 3, and the concave plate component can slide on the frame component through the sliding cooperation between the slide rail 8 and the slide groove 20 (the specific structure of the slide groove 20 is described below).
[0068] In this embodiment, combined Figure 2 As shown, the slide rail 8 is a hollow structure, and the connecting component is arranged in the slide rail 8; the connecting component includes a fixing plate and a connecting pin 12.
[0069] Specifically, fixing plates are respectively provided at both ends of the slide rail 8 along the length direction thereof, and adjacent fixing plates of adjacent concave plate members are connected by connecting pins 12 .
[0070] Furthermore, the connection method of the connecting member is elaborated in detail by taking the first concave plate member 1 and the second concave plate member 26 as examples; three fixing plates are arranged on the first concave plate member 1 and the second concave plate member 26, namely the first fixing plate 11, the second fixing plate 13 and the third fixing plate 14, wherein the first fixing plate 11 and the second fixing plate 13 on the first concave plate member 1 (there is a gap between the first fixing plate 11 and the second fixing plate 13) are arranged at the end of the first concave plate member 1 away from the second concave plate member 26, the third fixing plate 14 is arranged at the end of the first concave plate member 1 close to the second concave plate member 26, the first fixing plate 11 and the second fixing plate 13 on the second concave plate member 26 are arranged at the end of the second concave plate member 26 close to the first concave plate member 1, and the third fixing plate 14 is arranged at the end of the second concave plate member 26 away from the first concave plate member 1.
[0071] Furthermore, a pin hole is formed on the third fixing plate 14 , and the pin hole is coaxial with the connecting pin 12 .
[0072] Furthermore, one end of the connecting pin 12 is fixed to the second fixing plate 13 and passes through the first fixing plate 11 .
[0073] In the actual installation process: first, the first concave plate member 1 is slid to the frame member in a sliding manner, and then the second concave plate member 26 is slid toward the first concave plate member 1 in a sliding manner. When the second concave plate member 26 is close to the first concave plate member 1, the connecting pin 12 on the first fixing plate 11 and the second fixing plate 13 on the second concave plate structure is just inserted into the pin hole on the third fixing plate 14 on the first concave plate member 1, thereby realizing the fixed connection between the first concave plate member 1 and the second concave plate member 26.
[0074] In the actual disassembly structure: the second concave plate member 26 is directly pulled and pulled toward and away from the first concave plate member 1. During the pulling and pulling process, the second fixing plate 13 on the second concave plate member 26 and the connecting pin 12 on the first fixing plate 11 will be pulled out from the pin hole of the third fixing plate 14 on the first concave plate member 1, so that the second concave plate member 26 can be slid off the frame member.
[0075] Preferably, the connecting pin 12 is a cylindrical pin or a prismatic pin. When the connecting pin 12 is a cylindrical pin, the pin hole is a round hole. When the connecting pin 12 is a prismatic pin, the pin hole is a prismatic hole.
[0076] In summary, the structural mode of multiple concave plate components, when connected by connecting components, is convenient and simple in the entire process of installation and disassembly. That is to say, when a concave plate component needs to be cleaned, repaired or inspected, the disassembly and installation of the concave plate component can be achieved directly by this pulling and pulling method.
[0077] In this embodiment, a frame structure is provided, wherein the frame member includes a frame crossbeam.
[0078] Specifically, a plurality of frame cross beams are provided, and the plurality of frame cross beams are arranged at intervals along the second direction 9 , so that an installation space 5 is formed between adjacent frames.
[0079] Specifically, adjacent frames are provided with slide grooves 20 extending along the first direction 3 toward opposite sides, and the slide rails 8 can move in the slide grooves 20 so that the concave plate components can be removed from the frame cross beams.
[0080] It is worth noting that: at this time, the adjacent frame beams are arranged at intervals and are not arranged closely.
[0081] In this embodiment, combined Figure 4 As shown, another frame structure is provided, and the frame components include frame beams; there are four frame beams, namely a first frame beam 16, a second frame beam 17, a third frame beam 18 and a fourth frame beam 19, the first frame beam 16 and the second frame beam 17 are arranged at intervals to form an installation space 5, the second frame beam 17 and the third frame beam 18 are connected and not arranged at intervals, and the third frame beam 18 and the fourth frame beam 19 are arranged at intervals to form an installation space 5.
[0082] Specifically, the first frame crossbeam 16 and the second frame crossbeam 17 are provided with a slide groove 20 extending along the first direction 3 on the side walls facing the opposite sides, and the third frame crossbeam 18 and the fourth frame crossbeam 19 are provided with a slide groove 20 extending along the first direction 3 on the side walls facing the opposite sides; the slide rail 8 can move in the slide groove 20 so that the concave plate component can be removed from the frame.
[0083] More specifically, the frame member further includes a limiting plate 21 and a connecting frame 22 ; wherein the limiting plate 21 and the connecting frame 22 are respectively disposed at two ends of the installation space 5 along the first direction 3 and are located below the slide slot 20 .
[0084] Further, Figure 4 The placement of the installation space 5 is based on the paper, the end of the installation space 5 facing the outside of the paper is the sealing end, and the end of the installation space 5 facing the inside of the paper is the inlet and outlet end (when installing or removing the concave plate component, the upper or lower concave plate component is installed through the inlet and outlet ends), then combined with Figure 6 As shown, the connecting frame 22 is arranged at the inlet and outlet ends, and the two ends of the connecting frame 22 are respectively connected to adjacent frames and are located below the slide rail 8; in this way, the connecting frame 22 can act as a limiter. When the pull-out multi-section concave plate harvester is working, since the concave plate component is slidably arranged on the frame, the connecting frame 22 can be used to prevent the concave plate component from sliding off the frame.
[0085] Furthermore, the limiting plate 21 is arranged at the sealing end, and both ends of the limiting plate 21 are respectively connected to adjacent frames and are located below the slide rail 8; such an arrangement prevents the concave plate component from sliding out of the frame from the sealing end.
[0086] In this embodiment, combined Figure 7 As shown, the frame member further includes a spacer 15 .
[0087] Specifically, the cushion block 15 is disposed at one end of the slide slot 20 along the first direction 3 and away from the connecting frame 22 , that is, the cushion block 15 is disposed at the sealing end and located on the slide slot 20 .
[0088] Furthermore, a pin hole coaxial with the connecting pin 12 is formed on the cushion block 15 .
[0089] During the installation of the first concave plate component 1, the first concave plate component 1 first slides from the inlet and outlet ends to the frame in a sliding manner (the slide rail 8 cooperates with the slide groove 20) until the connecting pins 12 on the first fixing plate 11 and the second fixing plate 13 on the first concave plate component 1 are inserted into the pin shaft holes of the cushion block 15, thereby fixing the first concave plate component 1 on the frame.
[0090] In this embodiment, combined Figure 5 As shown, the frame member also includes a locking member.
[0091] Specifically, the locking member is disposed in the slide groove 20 and abuts against one end of the slide rail 8 close to the connecting frame 22 , so that the recessed plate member is restricted in the installation space 5 .
[0092] Furthermore, taking four concave plate components as an example, the locking component is arranged in the slide groove 20 and abuts against one end of the slide rail 8 of the fourth concave plate component 28 close to the connecting frame 22, that is, the four concave plate components can be limited in the installation space 5 to prevent the four concave plate components from moving in the installation space 5.
[0093] Furthermore, the locking member 25 passes through one end of the slide rail 8 close to the connecting frame 22 to fix the slide rail 8 to the frame crossbeam.
[0094] Preferably, the locking member 25 is a bolt.
[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application 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 application.
