[0059] The separation chamber of a traditional harvester includes a frame, a front support plate and a rear support plate. Along the length direction of the frame, the front support plate and the rear support plate are respectively connected to both ends of the frame. Two concave plate sieve installation areas extending along the length direction and arranged side by side along the width direction are formed inside the frame. The concave plate sieve installation areas are used to install and fix the fixed concave plate and the movable concave plate. There is a support structure between the two concave plate sieve installation areas for installing and fixing the fixed concave plate and the movable concave plate. Along the length direction of the frame, the front part of the concave plate sieve installation area is the threshing section, which is used to install the movable concave plate for threshing operations; the rear part of the concave plate sieve installation area is the separation section, which is used to install the fixed concave plate for separation operations.

[0060] However, the support structure of the separation chamber of traditional harvesters is generally fixedly connected to the frame, front support plate, and rear support plate by welding or other means. When it is necessary to replace the concave sieve, it is necessary to enter the interior of the separation chamber for disassembly and assembly, which is inconvenient and time-consuming. Based on this, this embodiment proposes an installation mechanism (hereinafter referred to as the installation mechanism) for facilitating the disassembly and assembly of the concave sieve and a separation chamber including this installation mechanism. By setting this installation mechanism, the convenience of disassembling and assembling the concave sieve can be improved to a certain extent.

[0061] The following will further describe in detail the installation mechanism for facilitating the disassembly and assembly of the concave sieve in this embodiment and the separation chamber including this installation mechanism through specific embodiments and in combination with the attached Figures 1 to 13 drawings.

[0062] The installation mechanism 1 of this embodiment is a support structure with a new structural design, which is located between two concave sieve installation areas for installing and fixing the concave plate 5 and the movable concave plate 6.

[0063] As Figure 1 shown in and in combination with Figure 2 and Figure 3 the drawings, the installation mechanism 1 includes a beam assembly 11, a mounting plate 12, and a concave plate connection assembly 13. The length direction of the beam assembly 11 is the length direction of the separation chamber. The mounting plate 12 is connected to both ends of the beam assembly 11 in the length direction. The mounting plate 12 is provided with mounting holes, and the mounting plate 12 is detachably connected to the support plate of the separation chamber through the mounting holes in cooperation with fasteners. The concave plate connection assembly 13 is connected to the beam assembly 11, and the concave plate connection assembly 13 includes a plurality of connecting members for connecting the concave plates of the separation chamber, thereby realizing the connection between the concave plates and the beam assembly 11. That is, a mounting plate 12 is provided at each end of the beam assembly 11 in the long end direction. One mounting plate 12 is detachably connected to the front support plate 3 through the mounting holes in cooperation with fasteners, and the other mounting plate 12 is detachably connected to the rear support plate 4 through the mounting holes in cooperation with fasteners, thereby realizing the disassembly and assembly of the beam assembly 11 and the separation chamber frame 2 and the support plate, and further realizing the overall disassembly and assembly of the concave plate, the concave plate connection assembly 13, and the beam assembly 11 relative to the separation chamber frame 2 and the support plate. Especially when the fasteners extend outside the separation chamber, the beam assembly 11, the concave plate, and the concave plate connection assembly 13 can be disassembled outside the separation chamber, and the disassembly is more convenient and time-saving.

[0064] Specifically, the beam assembly 11 includes an upper cross beam 111, a lower cross beam 112, and a connecting plate 113.

[0065] As Figure 1 shown in and in combination with Figure 2 and Figure 4As shown, the upper crossbeam 111 and the lower crossbeam 112 both extend along the length direction of the frame 2 of the separation chamber, and the two are arranged in parallel at an interval. The upper crossbeam 111 is located above the lower crossbeam 112. The connecting plate 113 is connected between the upper crossbeam 111 and the lower crossbeam 112. A plurality of connection hole positions are respectively formed on the upper crossbeam 111 and the lower crossbeam 112. The upper end of the connecting plate 113 can be connected to the connection hole position of the upper crossbeam 111 through fasteners such as bolts 15, and the lower end of the connecting plate 113 can be connected to the connection hole position of the lower crossbeam 112 through fasteners such as bolts 15. The connecting plate 113 can increase the overall strength of the mounting mechanism 1. And, preferably, the plate surface of the connecting plate 113 is arc-shaped, and the number of the connecting plates 113 is two. The two connecting plates 113 are arranged back to back with each other and respectively extend to both sides in the length direction of the beam assembly 11. The arc-shaped connecting plate 113 can serve as a part of the side wall of the concave sieve installation area, and together with the concave sieve, it forms the corresponding separation section 7 and threshing section 8. The connecting plate 113 can play a role in preventing grain splashing.

[0066] As Figure 4 shown, the upper crossbeam 111 can adopt a rectangular steel pipe 1111, and a welding sleeve 1112 is welded inside it to enhance the strength of the upper crossbeam 111 and prevent the upper crossbeam 111 from deforming when being firmly connected through fasteners such as bolts 15. The mounting plate 12 can be connected to the end of the upper crossbeam 111 through fasteners, or can be connected to the end of the lower crossbeam 112 through fasteners, or can be connected to the ends of both the upper crossbeam 111 and the lower crossbeam 112 through fasteners.

[0067] As Figures 5 to 7 shown, the lower crossbeam 112 includes a concave sieve hanging beam 1121, a nut positioning plate 1123 and a mounting bracket 1122. A plurality of connection hole positions are formed on the concave sieve hanging beam 1121 at intervals along the length direction to connect the above-mentioned connecting plate 113, etc. The mounting brackets 1122 are connected to both ends in the length direction of the concave sieve hanging beam 1121. Connection hole positions are formed on the mounting brackets 1122, and the concave sieve hanging beam 1121 is connected to the frame 2 of the separation chamber through the mounting brackets 1122. The nut positioning plate 1123 is arranged inside the concave sieve hanging beam 1121, and the concave sieve connection assembly 13 is located outside the concave sieve hanging beam 1121 ( Figure 6 and Figure 7 under the concave sieve hanging beam 1121 as shown). Corresponding connection holes are formed on the concave sieve hanging beam 1121 and the nut positioning plate 1123, and fasteners connect the nut positioning plate 1123, the concave sieve hanging beam 1121 and the concave sieve connection assembly 13 through the connection holes.

[0068] As Figure 5 、 Figures 7 to 11As shown, the concave plate connection assembly 13 includes a plurality of first connectors 131 and a plurality of second connectors 132. The first connectors 131 are used to connect and fix the concave plate 5, and the second connectors 132 are used to connect the movable concave plate 6. The specific structures of the first connectors 131 and the second connectors 132 and their connection structures with the corresponding concave plates will be specifically introduced below.

[0069] As Figure 5 and Figure 8 shown, a plurality of first connectors 131 are arranged at intervals along the length direction of the concave plate suspension beam 1121 in the separation section 7 of the separation chamber. Each first connector 131 includes a first beam connection portion 1311 and a first concave plate connection portion 1312; the first beam connection portion 1311 has a groove-like structure and extends along the length direction of the concave plate suspension beam 1121. The depth and width of the first beam connection portion 1311 are adapted to the depth and width of the concave plate suspension beam 1121. The concave plate suspension beam 1121 passes through the first beam connection portions 1311 of the plurality of first connectors 131, and a cooperation structure similar to a track is formed between the first beam connection portion 1311 and the concave plate suspension beam 1121, which is more convenient for the installation and positioning between the two. In addition, positioning holes 133 are formed in both the concave plate suspension beam 1121 and the first beam connection portion 1311, and the first connector 131 and the concave plate suspension beam 1121 are connected by fasteners and the positioning holes 133.

[0070] The first concave plate connection portion 1312 is connected to both sides of the first beam connection portion 1311, and the first concave plate connection portion 1312 is a symmetric structure with respect to the first beam connection portion 1311, that is, the first concave plate connection portions 1312 are connected to both sides of the first beam connection portion 1311. The first concave plate connection portions 1312 on both sides face the separation sections 7 on both sides of the installation mechanism 1 respectively, and the first concave plate connection portion 1312 can be detachably connected to the fixed concave plate 5 of the corresponding separation section 7 through fasteners. Specifically, the first concave plate connection portion 1312 can be connected to the fixed concave plate 5 on the corresponding side through fasteners such as bolts 15, so as to realize the detachable connection between the fixed concave plate 5 and the installation mechanism 1. One end of the fixed concave plate 5 is connected to the first concave plate connection portion 1312 of the first connector 131, and the other end of the fixed concave plate 5 can be connected to the frame 2 of the separation chamber, so as to realize the assembly of the fixed concave plate 5.

[0071] The first connector 131 can be an integrally formed structure, that is, the first beam connection portion 1311 and the first concave plate connection portions 1312 on both sides are an integral structure, so as to improve the strength of the first connector 131.

[0072] As Figure 5 and Figure 9As shown, a plurality of second connecting members 132 are arranged at intervals along the length direction of the concave plate hanging beam 1121 in the threshing section 8 of the separation chamber. Each second connecting member 132 includes a second beam connecting portion 1321 and a second concave plate connecting portion 1322. Positioning holes 133 are formed in both the concave plate hanging beam 1121 and the second beam connecting portion 1321. The second connecting member 132 is connected to the concave plate hanging beam 1121 through fasteners and the positioning holes 133. For example Figure 9 as shown in, two positioning holes 133 are formed in each second beam connecting portion 1321; the second concave plate connecting portion 1322 is connected to both sides of the second beam connecting portion 1321, that is, the second concave plate connecting portions 1322 are respectively connected to both sides of the second beam connecting portion 1321, and the second concave plate connecting portion 1322 is a symmetric structure relative to the second beam connecting portion 1321. The second concave plate connecting portions 1322 on both sides respectively face the threshing sections on both sides of the mounting mechanism 1. The movable concave plate 6 can be hung on the second concave plate connecting portions 1322 through the support frame 14.

[0073] Such as Figure 11 And Figure 12 And in combination with Figure 9As shown in the figure, the support frame 14 includes a frame body 141, a mounting column 142 and a limiting block 143; the frame body 141 is an arc-shaped frame structure, which is adapted to the movable concave plate 6 so that the movable concave plate 6 can be assembled on the frame body 141; the mounting column 142 is connected to one end of the frame body 141 and is parallel to the arc surface formed by the frame body 141. The movable concave plate 6 is hung on the hanging groove 1323 through the mounting column 142. The width and depth of the hanging groove 1323 are adapted to the size of the mounting column 142 so that the mounting column 142 can be stably hung on the hanging groove 1323. A reinforcing rod 145 is also connected inside the frame body 141 to enhance the structural strength of the support frame 14. Two limiting card slots 1431 are formed on the limiting block 143. In the state where the movable concave plates 6 on both sides are respectively assembled with the two support frames 14, the mounting columns 142 of the two support frames 14 on both sides are respectively and correspondingly clamped with the two limiting card slots 1431 to prevent the movable concave plate 6 from rotating or falling downward. It should be noted that on both sides of the installation mechanism 1, a frame body 141 is respectively provided, each frame body 141 is correspondingly connected to a mounting column 142, a limiting block 143 is arranged between the two frame bodies 141, and the two limiting card slots 1431 on the limiting block 143 are respectively clamped with the mounting columns 142 on both sides. The limiting block 143 plays a limiting role on the frame bodies 141 and the mounting columns 142 on both sides, that is, the two mounting columns 142 are jointly connected to a limiting block 143. In addition, a plurality of limiting blocks 143 can also be provided, and each limiting block 143 is respectively connected to the mounting columns 142 on both sides. To better prevent the support frame 14 from moving axially along the mounting column 142 and other situations, a positioning ring 144 is also provided on the side of the limiting block 143 to limit the position of the limiting block 143 in the axial direction of the mounting column 142 to improve the structural stability of the movable concave plate 6 during operation.

[0074] Regarding the assembly structure between the movable concave plate 6 and the support frame 14, a connection position 16 is formed at the end of the frame body 141 away from the mounting column 142, and one end of the movable concave plate 6 is connected to the frame body 141 through a fastener and the connection position 16; a clamping position, such as a card slot structure, is formed at the other end of the movable concave plate 6, and it is connected to the mounting column 142 through the clamping position, thereby realizing the assembly of the movable concave plate 6 on the corresponding support frame 14.

[0075] It should be noted that the fasteners mentioned in this embodiment can all be and are preferably bolt structures, so as to achieve the effect that the overall structure is convenient for disassembly and assembly.

[0076] The mounting mechanism of this embodiment is connected to the support plate of the separation chamber through outer bolts, which facilitates the disassembly of the mounting mechanism and the main body of the separation chamber outside the separation chamber. When replacing the fixed concave plate, it is only necessary to disassemble the outer bolts and the first connecting member for connecting the fixed concave plate from the lower cross beam to achieve the replacement of the fixed concave plate. When disassembling the movable concave plate, disassemble the second connecting member for connecting the movable concave plate from the lower cross beam, and then disassemble the connecting bolts of the movable concave plate and the support frame, which reduces the time consumed for replacing the concave plate screen and improves the operation efficiency.
