Technical Field

[0001] The utility model relates to the technical field of auxiliary mobile crushing and mixing machines, in particular to a mobile auxiliary structure of a coal crushing and mixing machine. Background Art

[0002] When the coal crushing mixer is moving, a mobile auxiliary structure is needed to help the mixer move. The mobile auxiliary structure is usually a mobile base composed of wheels or tracks, which can easily move the mixer to different locations or workplaces when needed.

[0003] For example, publication number CN218365638U discloses a small concrete mixer with an auxiliary mobile structure, which includes a mixer body, a support platform, rollers and support legs, and a support platform is arranged below the mixer body.

[0004] However, in the prior art, when the mobile base moves on an uneven ground, the moving range is limited by the terrain. When encountering an uneven ground or a ground with obstacles, the mobility will be affected to varying degrees, thereby affecting the flexibility and applicability of the equipment.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a mobile auxiliary structure of a coal crushing mixer, including a bottom frame 1, the bottom of the bottom frame 1 is rotatably connected to a support assembly 2, the support assembly 2 includes a connecting block 21, the bottom of the connecting block 21 is fixedly connected to a support rod 22, both sides of the support rod 22 are rotatably connected to a first connecting rod 23, one end of the first connecting rod 23 is rotatably connected to a vertical rod 24, the bottom of the vertical rod 24 is rotatably connected to a support roller 25, the top of the connecting block 21 is fixedly connected to a positioning platform 26, the top of the positioning platform 26 is rotatably connected to the bottom of the bottom frame 1, an electric cylinder 27 is provided on one side of the vertical rod 24, both sides of the support rod 22 are rotatably connected to a second connecting rod 211, the second connecting rod 211 is located below the first connecting rod 23, the vertical rod 24 is rotatably connected to the second connecting rod 211, and a positioning rod 28 is fixedly installed inside the second connecting rod 211.

[0026] The specific settings and functions of this embodiment are described in detail below. The support assembly 2 is rotatably installed at the four corners of the bottom frame 1 to support the entire bottom frame 1. The bottom frame 1 is used to carry the pulverizer. When transporting the pulverizer, the machine is moved to the bottom frame 1, and then the bottom frame 1 is directly pushed. The support roller 25 in the support assembly 2 rotates to achieve the purpose of moving the pulverizer. Two support rods 22 are provided at the bottom of the connecting block 21 in the support assembly 2 to determine the position of the support roller 25. The connecting block 21 is rotatably connected to the bottom frame 1 through the positioning platform 26, which is convenient for adjusting the moving direction.

[0027] The support roller 25 is rotatably mounted on the vertical rod 24, and the vertical rod 24 is connected to the support rod 22 through the first connecting rod 23. The support rod 22 is mounted at the bottom of the connecting block 21. After moving to the target area, the support roller 25 is turned away to one side of the support rod 22 so that the bottom of the support rod 22 can contact the ground, thereby achieving the effect of fixing the bottom frame 1. When turning away from the support roller 25, the height of the support roller 25 will change to adapt to the uneven ground. The first connecting rod 23 and the second connecting rod 211 will rotate at the same time. The first connecting rod 23 is parallel to the second connecting rod 211. During the rotation process, it can ensure that the vertical rod 24 is always in a vertical state.

[0028] The electric cylinder 27 is used to push the vertical rod 24 to move. At the same time, the first connecting rod 23 and the second connecting rod 211 are rotatably connected to the support rod 22, which will determine the moving direction of the vertical rod 24. The extension and retraction of the screw rod in the electric cylinder 27 can also change the height of the bottom frame 1 to prevent the bottom frame 1 from contacting obstacles.

[0029] Embodiment 2

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a limit plate 210 is fixedly installed at the intersection of the support rod 22 and the positioning platform 26, one end of the electric cylinder 27 is rotatably connected to the limit plate 210, one end of the lead screw of the electric cylinder 27 is rotatably connected to the positioning rod 28, a blocking plate 29 is fixedly installed inside the first connecting rod 23 and inside the second connecting rod 211, a positioning frame 3 is fixedly installed on the lower surface of the bottom frame 1, a limit ring 4 is fixedly connected between the positioning frame 3 and the bottom frame 1, the positioning platform 26 is rotatably connected to the limit ring 4, and a battery module 5 is fixedly installed on the lower surface of the bottom frame 1.

[0031] The effect achieved by the entire embodiment is that the limit plate 210 can determine the position of one end of the electric cylinder 27, and the positioning rod 28 determines the position of one end of the screw rod of the electric cylinder 27. When the screw rod in the electric cylinder 27 extends, it will push the support roller 25 to move toward one side of the support rod 22, so that the support roller 25 moves obliquely upward to reduce the height of the bottom frame 1. When the screw rod in the electric cylinder 27 is retracted, it will push the support roller 25 to move toward the support rod 22, so that the support roller 25 moves downward to raise the height of the bottom frame 1.

[0032] The positioning frame 3 is used to determine the position of the support assembly 2. The positioning platform 26 is rotatably connected to the limit ring 4 to determine the rotation center of the support assembly 2 to avoid the position of the center of gravity from being offset. The battery module 5 is mainly used to supply energy to the electric cylinder 27.

[0033] The use method and working principle of the device: When transporting the pulverizer, move the machine to the bottom frame 1, and then directly push the bottom frame 1 to achieve the purpose of moving the pulverizer. During the movement, the positioning platform 26 can rotate in the limit ring 4, which is convenient for adjusting the moving direction;

[0034] The support roller 25 in the support assembly 2 can reduce the overall resistance. When encountering an uneven ground, the height of the vertical rod 24 is adjusted by the electric cylinder 27. When the ground is convex, the screw rod in the electric cylinder 27 is controlled to extend to push the support roller 25 to move toward one side of the support rod 22. In this process, the first connecting rod 23 and the second connecting rod 211 will rotate at the same time, which can ensure that the vertical rod 24 is always in a vertical state.

[0035] When the ground is sunken, the lead screw in the electric cylinder 27 is controlled to be retracted, thereby driving the support roller 25 to move toward the support rod 22. The extension and retraction of the lead screw can also change the height of the bottom frame 1. After moving to the target area, the support roller 25 is turned away to one side of the support rod 22, so that the bottom of the support rod 22 can contact the ground, thereby fixing the bottom frame 1.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
