Technical Field

[0001] The utility model relates to the technical field of loaders, in particular to a loader windshield with a protection device. Background Technique

[0002] In road construction, especially in the construction of high-grade highways, loaders are used for operations such as filling and excavation of subgrade projects, aggregate collection and loading in asphalt mixture and cement concrete yards. In addition, it can also perform operations such as pushing soil, leveling the ground and towing other machinery. Due to the advantages of fast operation speed, high efficiency, good mobility and light operation of loaders, they have become one of the main types of machines in earthwork construction in engineering.

[0003] The working environment of loaders is often filled with gravel and other flying objects, which often hit the windshield when the machine is operating. However, some models try to solve this problem by adding some additional equipment, such as the utility model with the patent publication number CN216545673U. It is provided with a device that can prevent scratches. When small stones or other small objects hit the windshield, this device can prevent scratches on the windshield to a certain extent, thus protecting the integrity of the windshield. However, when a larger object impacts the windshield at high speed, even with the anti-scratch device, the windshield may still be damaged or even broken. And it may cause harm to the driver.

One end of the spring is fixed on one side of the glass frame, and the other end is in contact with a number of vertical grids. A number of horizontal grids are cross-arranged on the vertical grids. And both ends of the number of horizontal grids are inserted into the chute. On the side of the horizontal grid close to the glass frame, there is PVC transparent plastic between a number of fixing blocks. On the side of the four corners of the PVC transparent plastic close to the glass frame, a number of adjusting parts are provided. At the four corners of the glass frame, a number of mounting posts are fixed. A fixing hole is opened in the mounting post. A fixing bolt is connected in the fixing hole by thread. The fixing bolt fixes a fixing ring on the side of the mounting post away from the glass frame. The horizontal grid and the vertical grid are used in combination. The impact force generated by the stone hitting the grid is offset by the spring arranged at both ends of it. And the PVC transparent plastic arranged is used to resist the scratches on the glass caused by the stone.

[0006] Preferably, a groove with a certain depth is clamped at the intersection of the horizontal grille and the vertical grille, and the horizontal grille and the vertical grille are inserted crosswise together, which is convenient for separately replacing the grille damaged by impact.

[0021] Please refer to Figures 1-5, the present utility model provides a technical solution: a loader windshield with a protection device, including a glass frame 1. On one side of the glass frame 1, a number of fixing blocks 2 are arranged in a circular pattern. There is a certain distance between the number of fixing blocks 2 to form a chute 3. A number of sleeves 12 are fixed on the glass frame 1 within the chute 3. A slide bar 13 is provided within the sleeve 12. A spring 14 is sleeved outside the slide bar 13 and the sleeve 12. One end of the spring 14 is fixed on one side of the glass frame 1, and the other end abuts against a number of vertical grilles 7. A number of horizontal grilles 8 are cross - arranged on the vertical grilles 7. And both ends of the number of horizontal grilles 8 are inserted into the chute 3. On one side of the horizontal grille 8 close to the glass frame 1, a PVC transparent plastic 10 is provided between the number of fixing blocks 2. On one side of the four corners of the PVC transparent plastic 10 close to the glass frame 1, a number of adjusting parts 11 are provided. At the four corners of the glass frame 1, a number of mounting posts 5 are fixed. A fixing hole 9 is opened within the mounting post 5. A fixing bolt 4 is threadedly connected within the fixing hole 9. The fixing bolt 4 fixes a fixing ring 6 on the side of the mounting post 5 away from the glass frame 1. The horizontal grille 8 and the vertical grille 7 are used in cooperation. The impact force generated by a stone hitting the grille is offset by the spring 14 provided at both ends thereof. And the PVC transparent plastic 10 provided is further used to resist scratches on the glass caused by the stone.

[0022] Further, at the intersection of the horizontal grille 8 and the vertical grille 7, a groove with a certain depth is provided for each. The horizontal grille 8 and the vertical grille 7 are cross - inserted together, which is convenient for separately replacing the grille damaged by impact.

[0023] Further, the sleeve 12 is fixed on the side of the glass frame 1 close to the fixing block 2. The slide bar 13 is fixed at both ends of the number of horizontal grilles 8 and vertical grilles 7. The slide bar 13 is inserted into the interior of the sleeve 12. The slide bar 13 cooperates with the sleeve 12 to limit the displacement of the spring 14, enabling it to only stretch and contract, and preventing the spring 14 from tilting.

[0024] Further, the fixing ring 6 is in the shape of a square ring, which is convenient for limiting the grille in cooperation with the fixing block 2.

[0025] Further, the horizontal grille 8 and the vertical grille 7 are made of aluminum alloy, which not only has high strength but also is light in weight.

[0026] Working principle: The core of the utility model is to equip a protective device to improve the safety performance of the glass. The structure mainly includes a frame and multiple components fixed on the frame. A row of fixed blocks 2 arranged in a ring are arranged on one side of the frame, and a certain interval is maintained between them to form a slide groove 3. In the slide groove 3, several sleeves 12 are fixed on the frame, and a sliding rod 13 that can slide inside the sleeve 12 is inserted inside the sleeve 12, and a spring 14 is sleeved on the outside. One end of these springs 14 is fixed to the frame, and the other end is in contact with the two ends of several vertical grilles and transverse grilles 8. On these vertical grilles 7, transverse grilles 8 are arranged alternately, and their two ends are embedded in the slide groove 3. PVC transparent plastic 10 is arranged on the side of the grille close to the frame to increase the anti-scratch function. Near the four corners of the PVC transparent plastic 10, there are elements for adjustment to fine-tune the PVC transparent plastic 10. The four corners of the frame are equipped with mounting columns 5, in which 9 fixing holes are opened, and the fixing bolts 4 are connected by threads. These bolts anchor the fixing ring 6 to the side of the mounting column 5 away from the glass, preventing the grille from being separated from the slide slot 3, and ensuring the stability of the structure. When the protective device is in operation, the horizontal and vertical grilles 7 work together to absorb and alleviate the impact force generated by the impact of external objects such as flying stones by using the springs 14 at both ends. At the same time, the presence of the PVC transparent plastic 10 effectively prevents smaller objects from directly contacting the glass surface, reducing the possibility of the glass being scratched. The protective device of the loader windshield improves the damage resistance and service life of the glass through several designed structures, ensuring the clarity of vision and safety during the operation of the loader. At the intersection of the horizontal and vertical grilles 7, a groove with an appropriate depth is designed to achieve cross-connection between the two. Not only does it ensure the stability of the grille system, but also when a single grille is damaged due to external force impact, it can be replaced without affecting the integrity of the overall structure. The sleeve 12 is fixed to the side of the glass frame 1 close to the fixed block 2, providing necessary support for the stability of the system. In addition, slide bars 13 are fixed at both ends of the plurality of horizontal and vertical grids 7, and these slide bars 13 are inserted into the sleeve 12 to form a set of interaction structures. This structure limits the range of motion of the spring 14 through the cooperation between the sleeve 12 and the slide bars 13, so that the spring 14 can only perform telescopic motion along the axial direction, thereby effectively avoiding the problem of the spring 14 tilting under the action of force, and ensuring the normal operation and service life of the entire system.
