Description

Technical Field

[0001] This utility model relates to the field of grader technology, specifically to a grader with automatic width adjustment. Background Technology

[0002] Agricultural graders are used for leveling farmland. They typically consist of a bucket and a curved beam. The curved beam is connected to the tractor and pulls the bucket to move. When the bucket contacts the surface of the farmland, it moves the raised soil to the concave position, thus leveling the land to facilitate the cultivation of crops. It can also be used to clear snow, push loose materials, and maintain dirt roads and gravel roads.

[0003] Traditional graders, due to their fixed bucket width and lack of flexibility in their side structures, struggle to precisely meet the width requirements of different projects and complex terrain conditions. This results in low operating efficiency and inconsistent work quality, failing to fully meet the trends of high-efficiency and precision operations in modern engineering construction and agricultural production. Therefore, there is an urgent need to design a grader with automatically adjustable bucket width to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a grader with automatic width adjustment to address the aforementioned shortcomings in the prior art.

Two telescopic beam sleeves are provided on the back of the main bucket, and telescopic buckets are provided on both sides of the front surface of the main bucket. Two telescopic beams are welded to the back of the telescopic bucket, and the telescopic beams are inserted into the telescopic beam sleeves.

[0007] A connecting seat is provided at one end of the back of the telescopic bucket, and a telescopic hydraulic cylinder is rotatably connected to the connecting seat. A mounting seat is provided on one side of the connecting seat.

[0008] The telescopic bucket is provided with a folding bucket at one end, and a connector is provided at one end of the folding bucket. The connector is connected to the telescopic bucket. A second mounting base is provided at one end of the folding bucket, and a folding hydraulic cylinder is connected between the second mounting base and the second mounting base.

[0009] In a preferred embodiment of this utility model, one end of each of the two support columns is welded to the surface of the main bucket, and the other end of each column is provided with an installation slot. A second connecting seat is provided on one outer wall of the support column, and the second connecting seat is connected to the first connecting seat through the rotating shafts at both ends of the telescopic cylinder.

[0010] In a preferred embodiment of this utility model, the mounting slot is connected to a wheel assembly mechanism, the wheel assembly mechanism includes a connecting frame connected to the mounting slot, wheels are provided on both sides of the connecting frame, an adjusting cylinder is connected to the upper surface of the connecting frame, and the other end of the adjusting cylinder is connected to the frame.

[0011] In a preferred embodiment of this utility model, an adjusting cylinder two is connected between the frame and the top of the main bucket, and the angle of the main bucket can be adjusted by the adjusting cylinder two.

[0012] In a preferred embodiment of this utility model, the back of the main bucket is provided with a number of reinforcing ribs, which are located between two telescopic beam sleeves.

[0013] In a preferred embodiment of this utility model, the support column is provided with two secondary support beams, one end of which is fixed to the surface of the telescopic beam sleeve.

[0015] In the above technical solution, the automatic width-adjusting grader provided by this utility model has the following advantages:

[0016] (1) By setting up a telescopic bucket, the telescopic beam is slidably inserted into the telescopic sleeve beam to provide good support for the telescopic bucket. By pushing the telescopic cylinder, the telescopic bucket can move to both sides. At the same time, the telescopic cylinder and the telescopic bucket are at a certain angle, which can provide a certain support for the telescopic bucket. Under the action of the telescopic cylinder, the working area formed between the main bucket and the telescopic bucket can be adjusted. It can work in different width areas, which solves the problem that the existing grader has a relatively simple structure, the blade length is not adjustable, and the working area is limited, resulting in low working efficiency.

[0017] (2) By setting up a folding bucket, the width of the bucket can be changed by adjusting the angle between the folding bucket and the main bucket. At the same time, it can also increase the collection of soil and then fill the depression area without having to shovel soil multiple times for filling, thus improving work efficiency.
