Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0023] Reference Figure 1 - Figure 5The ear seat reinforcement part inside the arm body includes a large arm wall panel 1, and a stabilizing shaft 2 is fixedly connected inside the large arm wall panel 1. A reinforcement mechanism is provided at the bottom of the large arm wall panel 1, and the reinforcement mechanism includes a No. 1 reinforcement component and a No. 2 reinforcement component. The No. 1 reinforcement component and the No. 2 reinforcement component are used in conjunction with each other. The No. 1 reinforcement component includes an ear seat body 301, and the ear seat body 301 is arranged on one side of the bottom of the large arm wall panel 1. The ear seat body 301 is rotatably connected to a rotating shaft 302 inside the ear seat body 301, and the rotating shaft 302 is fixedly connected to the large arm wall panel 1. A reinforcement groove 303 is provided on one side of the top of the ear seat body 301, and a threaded rod 304 is rotatably connected inside the reinforcement groove 303. Two groups of threaded grooves are symmetrically provided on the outer side of the threaded rod 304, and the two adjacent threaded grooves are oppositely arranged. The outer side of the threaded rod 304 is threadedly connected to a No. 1 nut 305 and a No. 2 nut 306, and the No. 1 nut 305 and the No. 2 nut 306 are used in conjunction with each other. The second reinforcement component includes a mounting plate 4, which is fixedly connected to the bottom of the ear seat body 301, and a clamping plate 5 is equidistantly and symmetrically fixedly connected to the top of the mounting plate 4, and the clamping plate 5 is fixedly connected to the ear seat body 301, and a diagonal support plate 6 is fixedly connected to one side of the top of the mounting plate 4, and the bottom of the diagonal support plate 6 is fixedly connected to the top of the mounting plate 4.
[0024] In the above technical solution, it is considered that the connection between the arm of the excavator and the excavator body needs to be connected with an ear seat, but the connection of the above technology lacks a reinforcement mechanism for the ear seat. In actual use, the connection between the ear seat and the arm is prone to cracking, which affects the service life of the entire excavator nose. In order to solve this problem, the specific operations are as follows:
[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the threaded rod 304 is rotated, and the rotation of the threaded rod 304 drives the No. 1 nut 305 and the No. 2 nut 306 to move away from each other until the No. 1 nut 305 and the No. 2 nut 306 enter the interior of the mounting groove 7, until the No. 1 nut 305 and the No. 2 nut 306 form a support for the ear seat body 301. The clamping plate 5 is provided to support the bottom of the ear seat body 301. The clamping plate 5, the No. 1 nut 305 and the No. 2 nut 306 cooperate with each other through the reinforcement mechanism, and can form an effective support for the ear seat body 301. The inclined support plate 6 can provide auxiliary support for the ear seat body 301, making the ear seat body 301 more stable and preventing cracking, thereby extending the service life of the excavator arm body, and having a simple structure and strong practicality.
[0026] Reference Figure 1 - Figure 5In a preferred embodiment, the top of the ear seat body 301 is equidistantly provided with mounting grooves 7, which are pentagonal, and the sizes of the mounting grooves 7, the No. 1 nut 305 and the No. 2 nut 306 are the same. A rubber pad 8 is fixedly connected inside the mounting groove 7. A connecting shaft 9 is rotatably connected inside the big arm wall panel 1, and the connecting shaft 9 is used to connect the output end of the external cylinder. A connecting groove 10 is symmetrically provided on the outside of the connecting shaft 9, and a baffle 11 is symmetrically fixedly connected on the outside of the connecting shaft 9. Through the provided mounting groove 7, the No. 1 nut 305 and the No. 2 nut 306 can be limited to prevent the No. 1 nut 305 and the No. 2 nut 306 from rotating during the rotation of the threaded rod 304. Through the provided rubber pad 8, the friction between the No. 1 nut 305 and the No. 2 nut 306 and the ear seat body 301 can be reduced. Through the provided connecting shaft 9, the big arm wall panel 1 is conveniently connected to the external power device.
[0027] Working principle: In actual use, the staff connects the cylinder to the connecting shaft 9, and then rotates the threaded rod 304. The rotation of the threaded rod 304 drives the No. 1 nut 305 and the No. 2 nut 306 to move away from each other until the No. 1 nut 305 and the No. 2 nut 306 enter the interior of the installation groove 7, until the No. 1 nut 305 and the No. 2 nut 306 form a support for the ear seat body 301. The bottom of the ear seat body 301 can be supported by the provided splint 5. The splint 5, the No. 1 nut 305 and the No. 2 nut 306 cooperate with each other to form a support for the ear seat body 301.
