[0025] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] As Figure 1 、 Figure 4 shown, in this embodiment, a front guard plate of a slurry pump is proposed, which mainly includes a main board body 1. A buffer structure 2 is provided inside the main board body 1. The buffer structure 2 includes a first buffer layer 21, a reinforcement layer 22, and a second buffer layer 23. Elastic materials are filled in both the first buffer layer 21 and the second buffer layer 23. The elastic material in this embodiment is preferably an elastic material with a long service life such as fluororubber to fully ensure the service life of this embodiment; with the elasticity of the elastic material, when solid particles impact this embodiment and transfer the impact force to the first buffer layer 21 or the second buffer layer 23, the elastic material will be quickly deformed under the action of the impact force. In this elastic deformation process, the impact force on the transmission of other components or structures can be effectively reduced, thus playing a role in vibration damping and impact resistance; moreover, during the elastic deformation process, the external impact force will be dispersed to other surfaces or interiors as the elastic material deforms, and by expanding the action range of the force, the local force on this embodiment can be reduced; at the same time, the elastic material has good resilience and can quickly return to its original state after deformation, so as to ensure that the first buffer layer 21 and the second buffer layer 23 in this embodiment can be impacted multiple times without losing their buffer effect and ensure the service life of this embodiment.

[0028] Moreover, through the mutual cooperation of the first buffer layer 21 and the second buffer layer 23 in this embodiment, the effect of multiple protections is achieved, so that when this embodiment is subjected to impacts, the impact force can be buffered layer by layer, providing more comprehensive protection for this embodiment.

[0029] The strengthening layer 22 is located between the first buffer layer 21 and the second buffer layer 23. Through the combination of the three, the impact force is reduced by the buffer layer, and the strengthening layer 22 provides additional support for the first buffer layer 21 or the second buffer layer 23, providing sufficient toughness and strength for the main board body 1, thereby ensuring that the first buffer layer 21 or the second buffer layer 23 can be more stable and durable when subjected to long-term impact or vibration.

[0030] An auxiliary frame 3 is provided outside the main body 1, and a protective lining 4 and a connecting plate 5 are provided on the auxiliary frame 3. The protective lining 4 is fixedly connected to one end of the auxiliary frame 3 close to the first buffer layer 21, that is, the direct contact between the main body 1 and the medium such as solid particles is reduced by the protective lining 4, so as to prevent the main body 1 from being damaged by the impact of solid particles from occurring at the root, thereby extending the service life of this embodiment; the connecting plate 5 is fixedly connected to one end of the auxiliary frame 3 close to the second buffer layer 23. The existence of the connecting plate 5 itself is to balance the force of the auxiliary frame 3 as a whole on the main body 1, so as to facilitate the main body 1 to follow the slurry pump to work and ensure the stability of the operation of this embodiment. However, since the existence of the connecting plate 5 is likely to block the connecting hole of the main body 1 itself, the connecting hole design on the main body 1 can be cancelled, and the connecting hole can be designed at the corresponding position of the connecting plate 5 instead, which not only further improves the stability of the overall structure of the main body 1, but also facilitates the installation of this embodiment in the slurry pump, killing two birds with one stone.

[0031] Meanwhile, a wear-resistant coating 7 is provided on the protective lining 4 to reduce the damage caused by friction, wear, corrosion and the like caused by contact between the protective lining 4 and the material, thereby extending the service life of the protective lining 4.

[0032] like Figures 4 to 5 As shown, the reinforcement layer 22 in this embodiment includes a plurality of reinforcement bodies 221, and both ends of each reinforcement body 221 are respectively fixedly connected to the first buffer layer 21 and the second buffer layer 23, and each reinforcement body 221 is a triangular structure, that is, with the help of the good stability and rigidity of the triangle, it can effectively resist the impact force from the outside, so that the reinforcement layer 22 is not easy to be deformed and damaged when subjected to force, and the overall structure is more stable, which fully guarantees the strength of the overall structure of the reinforcement layer 22.

[0033] Furthermore, the projection surfaces of adjacent reinforcing bodies 221 on the vertical horizontal plane are staggered with each other, making full use of the internal space of the reinforcing layer 22, so that there are as many triangular structures as possible in the reinforcing layer 22 to ensure space utilization; and due to the staggered design of each reinforcing body 221, the force transmitted to the reinforcing layer 22 can be effectively dispersed, avoiding stress concentration in the reinforcing layer 22 under the action of external force, and fully ensuring the seismic resistance of the overall structure of the reinforcing layer 22.

[0034] The total height of the first buffer layer 21 and the second buffer layer 23 is less than the height of the reinforcement layer 22. That is, the reinforcement layer 22 occupies a relatively large proportion in the buffer structure 2. Compared with the situation where the reinforcement layer 22 occupies a small proportion, the overall stiffness and strength of the buffer structure 2 have been significantly improved, thereby enhancing the anti-extrusion and anti-impact performance of the entire main board body 1, making it more stable and reliable when bearing external forces.

[0035] Meanwhile, a number of support columns 6 are provided in the second buffer layer 23. Both ends of each support column 6 are fixedly connected to one end of the second buffer layer 23 close to the reinforcement layer 22 and one end of the second buffer layer 23 far from the reinforcement layer 22 respectively. The existence of each support column 6 enables the first buffer layer 21 and the reinforcement layer 22 to not only rely on the elastic forces of the outer shell of the main board body 1 and the second buffer layer 23 to maintain the stability of the overall structure, but also enables the first buffer layer 21 and the reinforcement layer 22 to obtain more direct and effective support points, avoiding the second buffer layer 23 and the reinforcement layer 22 from sagging and deforming downward during long-term operation, and ensuring the stability and reliability of the overall structure of this embodiment.

[0036] Embodiment 2

[0037] As Figures 2 to 3 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that: the support column 6 includes an upper column body 61, a lower column body 62, and an elastic member 63. Both the upper column body 61 and the lower column body 62 are annular structures. The upper column body 61 and the lower column body 62 are slidably connected and coaxially arranged. When the support column 6 is stressed, it can move by virtue of the force, thereby converting the impact energy into moving potential energy to achieve the purpose of absorbing the impact energy, thus avoiding the second buffer layer 23 and the reinforcement layer 22 from sagging and deforming downward. The elastic member 63 is located at the central position of the upper column body 61 and the lower column body 62. When the upper column body 61 moves, the elastic member 63 will also be stressed and deformed. Furthermore, through the deformation and recovery of the elastic member 63, the force that drives the second buffer layer 23 and the reinforcement layer to sag and deform is absorbed and dispersed, preventing the support column 6 from being broken under stress, ensuring the overall strength of the support column 6, and there should be a certain distance between the elastic material filling the second buffer layer 23 and the support column 6 to avoid the upper column body 61 squeezing the elastic material during movement, resulting in jamming of the upper column body 61.

[0038] The elastic member 63 in this embodiment is preferably an elastic element such as a compression spring with good anti-fatigue performance to ensure the service life of this embodiment.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
