Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a seat installation mechanism and a tractor with the same. Background Art

[0002] Most of the traditional tractors use seats without shock-absorbing structures. When installing the seats, a bracket is generally used to match the lower front end of the seat with the lifter below, and then the assembly is completed. At the same time, the rear end of the seat is directly assembled with the matching screw holes on the lifter through bolts passing through it.

[0003] However, with the development of agricultural machinery, new tractors generally use seats with shock absorbers (seat assemblies), and the lower end of the seat is generally provided with a shock absorber (surrounded by rubber). Therefore, the conventional seat installation method cannot be used when installing the seat, or the conventional seat installation method is difficult to use, and the lifter or seat needs to be modified.

[0004] Based on this, it is necessary to develop an installation mechanism that facilitates the rapid assembly of seats in new models. Utility Model Content

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the upper mounting plate is assembled with the lower end of the seat assembly by means of a first bolt penetrating the upper mounting plate from bottom to top.

[0010] Furthermore, a first weight-reducing hole is provided on the upper mounting plate.

[0011] Furthermore, the lower mounting plate is assembled with the upper end of the lifter by means of a second bolt penetrating the lower mounting plate from top to bottom.

[0012] Furthermore, a second weight-reducing hole is provided on the lower mounting plate.

[0013] Furthermore, the above-mentioned mounting portion includes two fixing plates with U-shaped longitudinal sections, and the two fixing plates are fixed at intervals on both sides of the lower end of the above-mentioned upper mounting plate. The lower end of the above-mentioned fixing plate is fitted with the upper part of the above-mentioned lower mounting plate, and is connected and assembled by multiple third bolts passing through the two.

[0014] Furthermore, bolt assembly and disassembly holes are respectively provided on the upper mounting plate at locations corresponding to the third bolts.

[0015] Furthermore, a vertically arranged reinforcing rib plate is fixed in the middle of the upper mounting plate, and the lower end of the reinforcing rib plate abuts against the upper end of the lower mounting plate.

[0016] Furthermore, the upper mounting plate, the lower mounting plate and the fixing plate are all sheet metal parts, and the fixing plate is fixed to the upper mounting plate by welding.

[0025] 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 and are not used to limit the scope of the present invention.

[0026] Example 1

[0027] like Figure 1 As shown, the seat mounting mechanism of this embodiment includes an upper mounting plate 1 and a lower mounting plate 2 which are respectively horizontally arranged, the lower mounting plate 2 is mounted on the upper end of the lifter, and the upper mounting plate 1 is mounted on the lower end of the seat assembly, a mounting portion is protruding from the lower end of the upper mounting plate 1, and the mounting portion is assembled and connected to the lower mounting plate 2, and the upper mounting plate 1 and the lower mounting plate 2 define the installation height of the seat.

[0028] The installation process is as follows:

[0029] First, assemble the upper mounting plate 1 with the seat assembly, and then assemble the lower mounting plate 2 with the upper end of the riser, and then move the seat assembly and the upper mounting plate 1 to the upper end of the lower mounting plate 2, and assemble the upper mounting plate 1 with the lower mounting plate 2, wherein the shape of the upper mounting plate 1 is adapted to the lower end of the seat assembly, and a convenient method for quick assembly with the seat assembly (such as bolt connection, etc.) is used to achieve quick connection, and the shape of the lower mounting plate 2 is adapted to the upper end of the riser assembly, and a convenient method for quick assembly with the riser (such as bolt connection, etc.) is used to achieve quick connection, and then the upper mounting plate 1 is stacked on the lower mounting plate 2 and a conventional plate connection method (screw connection or welding, etc.) is used for quick assembly. Since the seat assembly is a standardized product and the riser is also a standardized product, in order to ensure the height of the seat assembly after assembly, a mounting part is provided at the lower end of the upper mounting plate 1, and the overall height of the mounting part ensures the additional adjustment height of the seat assembly. Specifically, the mounting part can match the size according to actual needs to ensure that the distance between the bottom of the seat assembly and the upper end of the riser meets the set value after installation.

[0030] In this embodiment, the mounting portion is pre-installed on the lower end of the upper mounting plate 1, and then the upper mounting plate 1 and the lower end of the seat assembly are assembled.

[0031] As a preferred embodiment, the upper mounting plate 1 is assembled with the lower end of the seat assembly by means of a first bolt 12 penetrating the upper mounting plate 1 from bottom to top.

[0032] In the above embodiment, a first through hole (indicated by a in the figure) adapted to the first bolt 12 is opened on the upper mounting plate 1. The position of the first through hole ensures that it is adapted to the screw hole at the lower end of the seat assembly (matching hole). Then the first bolt 12 passes through the upper mounting plate 1 from bottom to top and is threadedly connected to the screw hole. The assembly is very quick and convenient.

[0033] As a preferred embodiment, Figure 3 As shown, the upper mounting plate 1 is provided with a first weight-reducing hole 13 .

[0034] In the above embodiment, the design of the first weight-reducing hole 13 reduces weight, saves consumables, and reduces costs.

[0035] As a preferred embodiment, the lower mounting plate 2 is assembled with the upper end of the lifter by means of a second bolt 21 penetrating the lower mounting plate 2 from top to bottom.

[0036] In the above embodiment, a second through hole adapted to the second bolt 21 is opened on the lower mounting plate 2, and the position of the second through hole is adapted to the screw hole at the upper end of the lifter (matching hole), and then the second bolt 21 is passed through the lower mounting plate 2 from top to bottom, and then threadedly connected to the screw hole at the upper end of the lifter, and the assembly is very quick and convenient.

[0037] As a preferred embodiment, a second weight-reducing hole is provided on the lower mounting plate 2 .

[0038] In the above implementation scheme, the design of the second weight-reducing hole reduces weight, saves consumables, and reduces costs.

[0039] As a preferred embodiment, Figure 1 , 4 As shown, the above-mentioned mounting portion includes two fixing plates 111 with a U-shaped longitudinal section. The two fixing plates 111 are fixed at intervals on both sides of the lower end of the above-mentioned upper mounting plate 1. The lower end of the above-mentioned fixing plate 111 is fitted with the upper part of the above-mentioned lower mounting plate 2, and is connected and assembled by a plurality of third bolts 112 passing through the two.

[0040] In the above implementation scheme, the mounting portion adopts two straight-shaped fixing plates 111 with a U-shaped longitudinal section. The two fixing plates 111 are parallelly and spaced apart on both sides of the lower end of the upper mounting plate 1. A third through hole adapted to the third bolt 112 is opened at a matching position on the bottom wall of the fixing plate 111 and the lower mounting plate 2. After the third bolt 112 passes through the third through hole from top to bottom, it can be locked by a nut.

[0041] In this embodiment, the upper mounting plate 1 is a T-shaped plate, and its two sides are exposed on both sides of the lower end of the seat assembly. The lower mounting plate 2 is a square plate, and its two sides are also exposed or suspended on both sides of the upper end of the lifter to facilitate the assembly of the third bolt 112.

[0042] As a preferred embodiment, bolt assembly and disassembly holes 14 are respectively opened at positions on the upper mounting plate 1 corresponding to the third bolts 112 .

[0043] In the above implementation scheme, the design of the bolt disassembly hole 14 allows the third bolt 112 to be lowered through the bolt disassembly hole 14 during assembly, pass through the third through hole, and then be locked with the nut, thereby avoiding the problem of entering the fixing plate 111 from the side and being unable to be effectively installed due to limited space. At the same time, when removing the third bolt 112, a tool can be inserted through the bolt disassembly hole 14, and the third bolt 112 can be taken out from the bolt disassembly hole 14 after removal.

[0044] As a preferred embodiment, Figure 2 As shown, a vertically arranged reinforcing rib plate 15 is fixed in the middle of the upper mounting plate 1 , and the lower end of the reinforcing rib plate 15 abuts against the upper end of the lower mounting plate 2 .

[0045] In the above embodiment, since the middle area between the upper mounting plate 1 and the lower mounting plate 2 is a cavity, a reinforcing rib plate 15 is provided at the cavity for support, thereby preventing the upper mounting plate 1 from bending and deforming during use of the seat, and effectively improving the overall structural strength.

[0046] In this embodiment, the first weight-reducing holes 13 and the second weight-reducing holes are respectively distributed in the area between the two fixing plates 111 .

[0047] As a preferred embodiment, the upper mounting plate 1 , the lower mounting plate 2 and the fixing plate 111 are all sheet metal parts, and the fixing plate 111 is fixed to the upper mounting plate 1 by welding.

[0048] In the above implementation scheme, the upper mounting plate 1 and the lower mounting plate 2 are both made of commonly used sheet metal parts, and the fixing plate 111 is made of bent sheet metal parts or channel steel, which is fixed to the lower end of the upper mounting plate 1 by welding, which is convenient to obtain materials and easy to assemble.
