Description

Technical Field

[0001] This utility model relates to the field of loading boom technology, specifically a high-strength loading boom. Background Technology

[0002] The working device of a loader includes a boom, attachments, a bucket-turning mechanism, and boom cylinders. Attachments are installed at the front end of the boom, and the rear end of the boom is connected to the front frame. The two ends of the boom cylinder are connected to the front frame and the boom, respectively, for raising and lowering the boom. Currently, the boom plate is a single piece; once the loader is manufactured, its length is fixed, and the loader's unloading height is also fixed, making further adjustment impossible. If the user needs to increase the unloading height, a loader equipped with a longer boom must be used. Therefore, those skilled in the art have provided a high-strength loader boom to solve the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength loading boom to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-strength loading boom includes two boom bodies arranged in parallel, with a main connecting frame fixed between the two boom bodies. A hinge shaft is sleeved on the front side of each of the two boom bodies, and an extension arm is rotatably connected to the surface of the hinge shaft. An adjustment mechanism is provided between the boom body and the extension arm.

[0006] As a further embodiment of this utility model: the adjustment mechanism includes a front connecting frame, which is fixed between the two extension arms and located at the rear end of the extension arms. A hydraulic cylinder is hinged to the surface of the main connecting frame, and the driving end of the hydraulic cylinder is hinged to the surface of the front connecting frame.

[0007] As a further improvement of this utility model: the front end of the extension arm is provided with a front connection hole, and the rear end of the boom body is provided with a rear mounting hole.

[0008] As a further improvement of this utility model, a weight reduction hole is provided through the surface of the boom body.

[0009] As a further improvement of this utility model, the upper surface of the main connecting frame is fixedly provided with an upper mounting hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By setting up an extension arm and hinged it to the front end of the boom body, the direction of the extension arm can be controlled by a hydraulic cylinder, which can increase the unloading height of the loader and also adjust the unloading angle. There is no need to equip a separate long boom, which makes it convenient for the loader to operate. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of a high-strength loading boom.

[0013] In the diagram: 1. Boom body; 2. Extension arm; 3. Hinge shaft; 4. Main connecting frame; 5. Rear mounting hole; 6. Hydraulic cylinder; 7. Front connecting frame; 8. Front connecting hole; 9. Weight reduction hole; 10. Upper mounting hole. Detailed Implementation

[0014] Please see Figure 1 In this embodiment of the utility model, a high-strength loading boom includes a boom body 1, two boom bodies 1 are arranged in parallel, and a main connecting frame 4 is fixedly connected between the two boom bodies 1. A hinge shaft 3 is sleeved on the front side of each of the two boom bodies 1, and an extension arm 2 is rotatably connected to the surface of the hinge shaft 3. An adjustment mechanism is provided between the boom body 1 and the extension arm 2.

[0015] Preferably, the adjustment mechanism includes a front connecting frame 7, which is fixed between the two extension arms 2 and located at the rear end of the extension arms 2. A hydraulic cylinder 6 is hinged to the surface of the main connecting frame 4, and the drive end of the hydraulic cylinder 6 is hinged to the surface of the front connecting frame 7.

[0016] Preferably, the front end of the extension arm 2 is provided with a front connection hole 8, and the rear end of the boom body 1 is provided with a rear mounting hole 5.

[0017] Preferably, a weight-reducing hole 9 is provided through the surface of the boom body 1 to reduce part of the boom's weight.

[0018] Preferably, the upper surface of the main connecting frame 4 is fixed with an upper mounting hole 10.

[0019] The working principle of this utility model is as follows: When using the loader boom, the boom can be installed to the front end of the loader from the rear mounting hole 5 and the upper mounting hole 10, and then the bulldozer blade and other equipment can be installed to the front connecting hole 8. When lifting and unloading are required, the front end of the boom body 1 can be raised. Furthermore, since the boom body 1 and the extension arm 2 are hinged, the direction of the extension arm 2 can be controlled by the hydraulic cylinder 6, thereby adjusting the unloading height angle of the loader and facilitating the operation.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
