Description

Technical Field

[0001] The utility model relates to the technical field of quick-disassembly of grass removal wheels, in particular to a grass removal wheel assembly structure and a harvester. Background Art

[0002] The main job of the grass discharge wheel of the combine harvester is to discharge the straw after threshing the grain. On the surface, the load on the grass discharge wheel is not large, but under different working conditions, its load will increase dramatically. For example, due to the small clearance between the grass discharge port and the concave plate and the grass discharge wheel, when discharging wet and complete straw, the grass discharge wheel will bear a large load. At the same time, the relevant load-bearing components on the grass discharge wheel are limited by the manufacturing process, and there are uncontrollable process defects, which are easy to be damaged under the working condition of excessive load.

[0003] The installation method of the grass wheel is mainly to open the bearing seat installation holes on the left and right side walls of the machine body (the side walls are the side installation plates), and the grass wheel is installed directly on the two side walls (using the two side walls to clamp it in the middle and fix it), and then fastened with bolts. Figure 1 shown.

[0004] Due to the structure of the grass wheel and its installation method, the whole machine cannot be disassembled for repair after damage, and disassembly and assembly are difficult, resulting in a long maintenance time. Specifically, since the grass wheel is clamped in the middle by the two side walls during installation, there are two ways to maintain it later: First, the main part of the grass wheel needs to be disassembled, taken out one by one, and then put back one by one; second, the grass wheel is taken out by removing the side wall (side mounting plate) of the whole vehicle. This is extremely complicated both from the perspective of the whole machine installation and from the perspective of later maintenance. Especially in later maintenance, it brings a lot of workload to users, delays the time of grain harvesting, leads to low returns, and cannot meet the needs of users. Utility Model Content

[0038] Example 1

[0039] In the prior art, due to the structure of the grass wheel 3 and its installation method, the grass wheel 3 cannot be disassembled as a whole for repair on the whole machine after it is damaged, and disassembly and assembly are difficult, resulting in a long repair time. From the perspective of installation and design, the grass wheel 3 is installed as a separate assembly, which is the most ideal state, but it is not actually possible. Instead, the grass wheel assembly is often disassembled and then assembled together with other assemblies on the harvester, which are restricted to each other and have a large number of secondary assembly problems, affecting the overall installation efficiency.

[0040] This application is aimed at this and the problems raised in the background technology, and designs a grass wheel assembly structure for use in a harvester, referring to Figure 2-Figure 4, which includes two side mounting plates 401 and a grass removal wheel assembly mounted on the two side mounting plates 401, wherein the two side mounting plates 401 do not belong to the grass removal wheel assembly, and therefore, the grass removal wheel assembly belongs to a separate assembly structure. In fact, the two side mounting plates 401 are arranged parallel to each other on the harvester body and are used to install the grass removal wheel assembly. For the convenience of distinction, the two side mounting plates 401 are respectively a first side mounting plate 1 and a second side mounting plate 2; the first side mounting plate 1 is provided with a first bearing seat mounting hole 101, and the second side mounting plate 2 is provided with a disassembly hole 201.

[0041] The grass removal wheel assembly includes a grass removal wheel 3 and a mounting seat 4, the grass removal wheel 3 includes a grass removal wheel shaft and a grass removal wheel body mounted on the grass removal wheel shaft, a first bearing seat 5 and a second bearing seat 6 are respectively arranged on the grass removal wheel shaft and on both sides of the grass removal wheel body, and the grass removal wheel shaft is simultaneously assembled in the bearing of the first bearing seat 5 and the bearing of the second bearing seat 6.

[0042] The mounting seat 4 is provided with a second bearing seat mounting hole 405 , and the second bearing seat 6 is mounted in the second bearing seat mounting hole 405 ; the mounting seat 4 is rotatably connected to the grass removal wheel 3 via the second bearing seat 6 .

[0043] The grass removal wheel 3 is inserted into the disassembly hole 201, and the first bearing seat 5 is installed in the bearing seat installation hole, and the installation seat 4 is detachably installed on the outer side of the second side installation plate 2. The size of the disassembly hole 201 is larger than the maximum outer diameter of the grass removal wheel 3, so the grass removal wheel 3 can pass through the disassembly hole 201.

[0044] In this embodiment, the disassembly hole 201 is designed to be a circular hole, and after the mounting seat 4 is connected to the second side mounting plate 2, it is necessary to ensure that the central axis of the second bearing seat mounting hole 405, the central axis of the disassembly hole 201 and the central axis of the first bearing seat mounting hole 101 are in the same straight line (collinear), thereby improving and ensuring the assembly accuracy and ensuring the smooth operation of the grass removal wheel 3 on the harvester.

[0045] In this embodiment, the mounting seat 4 includes a mounting plate 401, and the mounting plate 401 is provided with the disassembly hole 201; the mounting plate 401 and the second side mounting plate 2 are detachably connected in the following ways:

[0046] The first type: the mounting plate 401 is movably connected to the second side mounting plate 2 through a snap-fit ​​structure; for example, the snap-fit ​​structure adopts a snap-fit ​​structure, and the mounting plate 401 is movably connected to the second side mounting plate 2 through a plurality of snap-fit ​​structures; when the mounting seat 4 needs to be installed on the outside of the second side mounting plate 2, a plurality of snap-fit ​​structures are used to snap-fit ​​with the second side mounting portion. Alternatively, the snap-fit ​​structure includes a clamp and a slot, and the clamp structure can be designed in multiple groups, with a plurality of clamps provided on the mounting plate 401 and a plurality of slots provided on the second side mounting plate 2. When the mounting seat 4 needs to be installed on the outside of the second side mounting plate 2, the plurality of clamps on the mounting plate 401 are correspondingly snap-fitted into the plurality of slots on the second side mounting plate 2 to achieve the snap-fit.

[0047] The second type: the mounting plate 401 is suspended on the second side mounting plate 2. For example, a hook is provided on the mounting plate 401, and a suspension groove is provided on the second side mounting plate 2. One hook and one suspension groove form a group, and multiple groups can be provided on the mounting plate 401 and the second side mounting plate 2 at the same time. When the mounting seat 4 needs to be installed on the outer side of the second side mounting plate 2, the hook on the mounting plate 401 is correspondingly hung in the suspension groove on the mounting plate 401 to realize the hanging of the mounting plate 401 on the second side mounting plate 2.

[0048] The third type: the mounting plate 401 is connected to the second side mounting plate 2 by bolts, and a plurality of groups of bolt holes 403 are correspondingly arranged on the mounting plate 401 and the second side mounting plate 2, and a bolt assembly can be installed in each group of bolt holes 403 to bolt the two together and fix them.

[0049] In this embodiment, the mounting plate 401 and the second side mounting plate 2 are detachably connected by a third method, and in order to better facilitate the bolt connection therebetween, the mounting seat 4 also includes a connecting plate 402, which can be arranged on the side of the mounting plate 401, and a plurality of connecting plates 402 can be arranged, and the length of each connecting plate 402 can be different and can be designed according to actual conditions, and a plurality of bolt holes 403 are provided on each connecting plate 402, and bolt assemblies can be installed in the bolt holes 403. Preferably, the connecting plate 402 is perpendicular to the mounting plate 401, and the connecting plates 402 are respectively arranged on three adjacent sides of the mounting plate 401 (such as Figure 3As shown). The connecting plate 402 and the mounting plate 401 are integrally formed, or the connecting plate 402 and the mounting plate 401 are welded and fixed. Preferably, the connecting plate 402 and the mounting plate 401 are integrally formed, and the mounting plate 401 can be made of sheet metal. The three sides of the mounting plate 401 are respectively reserved with folded edges. The connecting plate 402 can be formed by simply bending the folded edges outward by 90° (outward, i.e., in the direction away from the main body of the grass removal wheel). A number of reinforcing plate ribs can also be provided between the upper and lower connecting plates 402 to improve the overall structural strength of the mounting seat 4.

[0050] The grass removal wheel assembly also includes a power input wheel 7, which is arranged on one end of the grass removal wheel shaft close to the mounting seat 4. The power input wheel 7 can be a pulley, a gear or a sprocket, and can be driven by the harvester's engine through belt drive, gear drive or chain drive.

[0051] A plurality of positioning holes 404 are respectively provided on the mounting plate 401 and the second side mounting plate 2. The positioning holes 404 on the mounting plate 401 correspond to the positioning holes 404 on the second side mounting plate 2 and are jointly provided with positioning pins to facilitate the positioning installation between the mounting seat 4 and the second side mounting plate 2, thereby improving the assembly accuracy of the grass removal wheel assembly and the two side mounting plates 401.

[0052] In this embodiment, three positioning holes 404 are provided on the mounting plate 401, which are respectively provided at the triangular positions of the mounting plate 401 (such as Figure 3 ), and three positioning holes 404 are correspondingly arranged on the second side mounting plate 2.

[0053] The present application improves the assembly structure of the grass removal wheel and changes its assembly method, so that the grass removal wheel assembly can be quickly disassembled and assembled on the two side mounting plates 401. Specifically, when assembling the grass removal wheel assembly, the grass removal wheel 3 is passed through the disassembly hole 201 of the second side mounting plate 2, and then the first bearing seat 5 is installed in the first bearing seat mounting hole 101 of the first side mounting plate 1, and then the mounting seat 4 is installed on the outside of the second side mounting plate 2 to complete the assembly of the grass removal wheel assembly; conversely, when the grass removal wheel assembly needs to be disassembled for maintenance, it is only necessary to disassemble the first bearing seat 5 and the mounting seat 4, and then pull the grass removal wheel assembly out of the disassembly hole 201. Through this structural design, when the grass removal wheel 3 is damaged, it can be removed without dismantling the two side walls (i.e. In the case of two side mounting plates 401), there is no need to disassemble the parts of the groove wheel assembly one by one. The grass removal wheel assembly can be quickly disassembled and maintained from the side of the second side mounting plate 2. This improves the maintenance efficiency and allows users to devote more time to operations, thereby reducing the user's workload during later maintenance, increasing profits, meeting user needs, and at the same time greatly improving the competitiveness of the company's products. Secondly, the mutual restriction problem between the grass removal wheel 3 and other assemblies on the harvester is solved, multiple secondary assemblies are avoided, assembly efficiency is improved, and the burden on staff is reduced.

[0054] Example 2

[0056] Example 3

[0057] A harvester comprises a machine body and the grass removal wheel assembly structure. The grass removal wheel assembly structure is mounted on the machine body via two side mounting plates 401.

[0058] The beneficial effects of the technical solution of the utility model are:

[0059] This solution solves the problem of installation and later maintenance convenience of the grass wheel 3. Maintenance angle: During later maintenance, the grass wheel 3 can be disassembled as a whole from one side of the second side mounting plate 2, which greatly improves the maintenance efficiency and saves maintenance time, so that more time can be invested in the operation, thus improving the operation efficiency of the whole machine, improving the performance of the product, and increasing user benefits. At the same time, the competitiveness of the company's products will be greatly improved. The installation angle solves the mutual restriction problem between the grass wheel 3 and other assemblies on the harvester, avoids multiple secondary assemblies, improves assembly efficiency, and reduces the burden on staff.
