Description

Technical Field

[0001] The utility model relates to the technical field of blade support, in particular to an inclined support device for a bulldozer blade. Background Art

[0002] A bulldozer is an engineering vehicle with a large metal blade installed in front of it. When in use, the blade is put down to shovel and push mud, sand and stones forward. The position and angle of the blade can be adjusted, and the bulldozer can complete the work of digging, transporting and unloading soil alone. The bulldozer has the characteristics of flexible operation, convenient rotation, small required working surface, and fast driving speed. The blade oblique support structure of a traditional engineering machinery bulldozer is in the form of a screw plus a sleeve. The angle between the blade and the ground plane is adjusted by an adjusting screw of the oblique support. The currently known bulldozer oblique support adjusting screw is a rectangular thread connection with a large thread pitch, a difficult manufacturing process, time-consuming, and high cost. In addition, the rectangular thread here has a short life and is easy to damage, and it is difficult to replace the oblique support, which will affect the normal working efficiency.

[0003] Currently, hydraulic adjustment is used in the market to adjust the blade body. Traditional hydraulic adjustment generally uses two hydraulic telescopic rods, which increases the cost of the entire support part. Therefore, how to solve this problem needs to be considered. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a bulldozer blade oblique support device. When in use, the device only uses a hydraulic telescopic rod to adjust the angle of the blade body. The cooperation of the guide plate and the guide groove can make the adjustment more stable.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A bulldozer blade oblique support device comprises a bucket body and a connecting frame, wherein two rectangular bars are symmetrically fixedly connected to the left side of the connecting frame, and two second U-shaped frames are symmetrically fixedly connected to the right side of the bucket body, and the left sides of the two rectangular bars are rotatably connected to the two second U-shaped frames respectively; a rotating mechanism, wherein the rotating mechanism comprises two second connecting rods symmetrically fixedly connected to the right side of the bucket body, and the right sides of the two second connecting rods are commonly fixedly connected to the first connecting rod, and the first U-shaped frame is installed on the upper end of the connecting frame, and a collar is penetrated on the first connecting rod, and a hydraulic telescopic rod is arranged above the connecting frame, and the telescopic end of the hydraulic telescopic rod is fixedly connected to the collar.

[0007] Preferably, the right end of the hydraulic telescopic rod is rotatably connected to the first U-shaped frame.

[0008] Preferably, the first connecting rod is rotatably connected to the collar via a bearing.

[0009] Preferably, two transverse plates are symmetrically fixedly connected to the right side of the bucket body, and two guide plates are symmetrically fixedly connected to the upper end of the connecting frame.

[0010] Preferably, guide grooves are provided through the two transverse plates, and each guide plate passes through a corresponding guide groove and is slidably connected to the corresponding guide groove.

[0011] Preferably, the inner wall surfaces on the left and right sides of each guide groove are arc-shaped surfaces.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The angle of the bucket body can be adjusted through a hydraulic telescopic rod. This method can effectively reduce the actual cost of the support part, and the controllable range of the adjustment angle is large. In addition, the setting of the guide plate can ensure the stability of the bucket body during rotation, and at the same time improves the overall stability of the support part. Compared with the existing technology, the stability of the support device part is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A bulldozer blade oblique support device comprises a bucket body 2 and a connecting frame 1, wherein the connecting frame 1 is mounted on the front side of the bulldozer, two rectangular bars 3 are symmetrically fixedly connected to the left side of the connecting frame 1, and two second U-shaped frames 10 are symmetrically fixedly connected to the right side of the bucket body 2, and the left sides of the two rectangular bars 3 are rotatably connected to the two second U-shaped frames 10 respectively;

[0020] Among them, it also includes a rotating mechanism, which includes two second connecting rods 12 symmetrically fixedly connected to the right side of the bucket body 2, and the right sides of the two second connecting rods 12 are commonly fixedly connected with the first connecting rod 4, and the upper end of the connecting frame 1 is installed with a first U-shaped frame 9, and the first connecting rod 4 is penetrated with a collar 8. The first connecting rod 4 is rotatably connected with the collar 8 through a bearing. The bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The use of bearings can ensure the support of the rotating connection. A hydraulic telescopic rod 5 is arranged above the connecting frame 1, and the telescopic end of the hydraulic telescopic rod 5 is fixedly connected to the collar 8, and the right end of the hydraulic telescopic rod 5 is rotatably connected to the first U-shaped frame 9, so that when the hydraulic telescopic rod 5 is contracted, the angle of the bucket body 2 can be adjusted;

[0021] Among them, two cross plates 6 are symmetrically fixedly connected to the right side of the bucket body 2, and two guide plates 7 are symmetrically fixedly connected to the upper end of the connecting frame 1. The guide plates 7 are arc-shaped plates. Guide grooves 11 are penetrated on the two cross plates 6. Each guide plate 7 penetrates the corresponding guide groove 11 and is slidably connected to the corresponding guide groove 11. The inner wall surfaces on the left and right sides of each guide groove 11 are arc-shaped surfaces.

[0022] In the utility model, when the angle of the bucket body 2 needs to be adjusted during use, it is only necessary to retract the hydraulic telescopic rod 5. When the hydraulic telescopic rod 5 is retracted, the bucket body 2 will rotate with the rotation connection of the second U-shaped frame 10 as the axis, and finally the angle adjustment of the bucket body 2 is achieved. In addition, the setting of the guide plate 7 can ensure the stability of the bucket body 2 when it rotates.

[0023] The entire adjustment process only requires one hydraulic telescopic rod 5 , without the need to use multiple hydraulic telescopic rods 5 , thereby reducing the cost of the entire device, and by using the guide plate 7 , the stability of the entire rotation is improved.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
