In this case, the front loading needs to be repeatedly installed and debugged during the installation process, which is bound to be cumbersome.

[0004] Based on this, it is necessary to develop a column structure that can realize rapid installation of front loading tools. Utility Model Content

[0023] 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.

[0024] Example: Figure 1 and 2As shown, the column structure of this embodiment that can realize the rapid installation of the front loading tool includes two columns 1 and two groups of connecting components 2. The two columns 1 have the same structure and are symmetrically distributed on both sides of the bracket 3. The lower ends of the two columns 1 are symmetrically equipped with a group of connecting components 2. The lower ends of the columns 1 are detachably connected to the corresponding sides of the bracket 3 through the connecting components 2. The upper ends of the columns 1 and the upper edges of the front sides are respectively provided with positioning notches 11 adapted to the front loading. The upper ends of the columns 1 are penetrated by locking holes 12 on the left and right sides for locking with the front loading.

[0025] During the installation process, two columns 1 are symmetrically assembled on the left and right sides of the bracket 3 of the tractor through two sets of connecting components 2. When installing the front loader, the connecting seat at one end of the front loader's boom is sleeved outside the column 1, and the rotating shaft of the connecting seat at one end of the boom is nested in the positioning notch 11 at the upper end of the column 1. The rotating shaft connected to the connecting seat at one end of the hydraulic cylinder on the front loader is nested in the positioning notch 11 at the upper front section of the column 1. The positioning of the front loader is achieved through these two positioning notches 11, and then the locking piece that penetrates the locking hole 12 and the corresponding through hole on the connecting seat at one end of the boom is locked with the connecting seat. In this way, the front loader can be positioned and assembled relatively quickly.

[0026] It should be noted that: in this embodiment, since the structures of the two columns 1 are the same, the columns 1 can be assembled without distinction between left and right, and the production of the columns 1 can save half of the mold cost. The two sets of connecting components 2 are also of the same structure, and one side can be installed on the other side by flipping 180 degrees. At the same time, multiple fixing points are set on the connecting component 2, which can provide fixed positions for other structures, thereby realizing the compactness of the small tractor and maximizing space utilization.

[0027] As a preferred implementation, the positioning notches 11 are all semicircular notches.

[0028] In the above embodiment, the shape of the positioning notch 11 is consistent with the shape of the nested rotating shaft, and the two are well matched to achieve relative rotation and precise nesting positioning.

[0029] As a preferred embodiment, the locking hole 12 is provided with a locking pin adapted for front loading.

[0030] In the above embodiment, after the connection seat at one end of the front loading arm is positioned with the column 1, the locking pin is operated to pass through the locking hole 12 and the through hole on the connection seat, and then the two ends of the locking pin are provided with limit members for limiting. Specifically, a locking cap is provided at one end of the locking pin, and the other end of the locking pin can be a screw, which is locked by screwing a locking nut.

[0031] In this embodiment, the pillar 1 is a plate-shaped member, and specifically, a high-strength sheet metal member made by die-casting can be used.

[0032] As a preferred embodiment, the inner side of the positioning notch 11 is integrally formed with a first arc-shaped lining 111 extending toward the left and right ends thereof.

[0033] In the above-mentioned implementation manner, the design of the first lining 111 can reduce the wear between the rotating shaft and the positioning notch 11 , and ensure that the rotating shaft and the first lining 111 have good relative rotation performance.

[0034] As a preferred embodiment, a second inner liner 121 having a cylindrical shape and extending toward the left and right ends thereof is coaxially disposed in the locking hole 12 .

[0035] In the above embodiment, the design of the second liner 121 can reduce the wear between the two after the locking pin is assembled.

[0036] In this embodiment, a reinforcement structure 13 is provided on the column 1. The reinforcement structure 13 can be a recess or a protrusion provided on the side of the column 1.

[0037] As a preferred embodiment, the connecting assembly 2 includes a first connecting seat 21 and a second connecting seat 22, one end of the first connecting seat 21 is detachably connected to the lower end of the column 1 by a high-strength bolt, and the other end of the first connecting seat 21 is respectively provided with a plate-shaped connecting portion 211 extending toward its front and rear ends, one of the connecting portions 211 is connected to the side end of the gearbox housing 31 (in a conventional tractor, one end of the bracket 3 in the front and rear direction is close to the end of the gearbox housing 31) by a high-strength bolt, and the other connecting portion 211 is connected to one end of the second connecting seat 22 by a high-strength bolt, and the other end of the second connecting seat 22 is attached to the side end of the bracket 3 and connected to the bracket 3 by a high-strength bolt.

[0038] In the above embodiment, since the gearbox housing 31 is provided at one end of the bracket 3 of the tractor, and the left and right sides of the gearbox housing 31 protrude from the two sides of the main body of the bracket 3, that is, there is a lateral distance between the side end of the gearbox housing 31 and the side end of the bracket 3, and the column 1 is generally installed at the joint between the bracket 3 and the gearbox housing 31, the lateral distance causes the column 1 to be unable to be directly installed, so the column 1 needs to be transferred to the bracket 3 through the connecting assembly 2. At the same time, considering the existence of the lateral distance, the connecting assembly 2 includes two parts, one of which is a first connecting seat 21 connected to the lower end of the column 1, a connecting portion 211 of the first connecting seat 21 is directly attached to the corresponding part of the side end of the gearbox housing 31, and is connected by high-strength bolts running through the two, and there is a large installation gap between the other connecting portion 211 and the side end of the bracket 3, and a second connecting seat 22 is arranged in the installation gap to realize the connection of the other connecting portion 211 with the side end of the bracket 3. Then, the column 1 is stably assembled with the bracket 3 and the gearbox housing 31 as a whole.

[0039] In this embodiment, a pipe-through passage is provided in the second connecting seat 22, which passes through the second connecting seat 22. The pipe-through passage is used to pass the hydraulic pipeline, so that the corresponding hydraulic pipeline wiring in the tractor is more compact and regular.

[0040] As a preferred embodiment, one end of the first connecting seat 21 is provided with a positioning groove running through it from top to bottom, and the lower end of the column 1 is provided with a positioning block 14 adapted to the positioning groove, and the positioning block 14 is embedded in the positioning groove and connected by a high-strength bolt running through the two.

[0041] In the above implementation scheme, the design of the positioning groove and the positioning block 14 can realize the positioning and assembly of the lower end of the column 1 and one end of the first connecting seat 21, ensuring that the columns 1 on both sides can be symmetrically assembled on both sides of the bracket 3, further simplifying the assembly difficulty of the column 1.
