Technical Field

[0001] This utility model relates to the field of engineering machinery cab technology, specifically to a movable windshield for an excavator loader cab. Background Technology

[0002] Excavator loaders are multi-functional engineering machines widely used in mining, tunneling, municipal engineering, and construction. They combine excavation and loading functions. The windshield, as the main transparent structural component in front of the cab, not only serves to protect against wind, dust, water, and impact, but also directly affects the driver's forward visibility.

[0003] However, fixed windshields cannot be adjusted in position according to actual operational needs, and fixed windshields limit the driver's operational flexibility, affecting work efficiency and safety. At the same time, excavators and loaders often face strong vibrations and impacts during operation, especially when working on uneven ground or complex terrain, which can easily damage the glass due to vibrations and impacts, increasing maintenance costs and potentially affecting the sealing of the cab.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a movable windshield for the cab of an excavator loader to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A movable windshield for a backhoe loader cab includes a windshield frame, movable components on both sides of the windshield frame, multiple movable rollers on both sides of the windshield frame, movable rails on the surfaces of the movable rollers, multiple limiting seats on the sides of the movable rails, limiting blocks engaged inside the limiting seats, one side of the limiting blocks connected to the side of the windshield frame, and a buffer component on the windshield frame.

[0007] Furthermore, in order to better cushion the windshield of the excavator loader cab, the cushioning assembly includes a sealing block on one side of the windshield frame, a fixed windshield frame connected to one end of the moving slide rail, a sealing seat on top of the fixed windshield frame, the two sides of the sealing seat contacting the sides of the moving slide rail, multiple shock absorbers inside the sealing seat, a buffer plate at one end of the shock absorber, and one side of the buffer plate and the inside of the sealing seat contacting one side of the sealing block.

[0008] Furthermore, in order to better move the windshield, the windshield is installed inside the windshield fixing frame and the windshield frame, and multiple handles are provided on one side of the windshield frame.

[0009] Furthermore, in order to better protect the windshield, multiple buffer pads are in contact with one side of the windshield, and a baffle is set on one side of the buffer pads. Multiple fixing screws are connected to the baffle, and one end of the fixing screws is connected to the windshield fixing frame and one side of the windshield frame.

[0010] Furthermore, in order to better restrict the windshield frame, a limiting groove is provided on the limiting seat, and a limiting block is set inside the limiting groove. One side of the limiting block is connected to a limiting rod through a bearing, and one end of the limiting rod is connected to the limiting seat.

[0011] Furthermore, in order to better seal the moving parts of the windshield frame, multiple mounting screws are connected to the sliding rail. One end of each mounting screw is connected to a sealing gasket, and one side of the sealing gasket contacts the side of the sliding rail.

[0012] The beneficial effects of this utility model are as follows: (1) The movable component installed in the windshield frame can be flexibly adjusted according to actual work needs, making it easy to quickly move the windshield according to the vision requirements, thereby obtaining a better field of vision angle and avoiding the obstruction of vision caused by fixed glass. This enables the excavator loader to complete the work tasks more efficiently under complex working conditions, improving the overall work efficiency and safety. The buffer component installed in the windshield frame can not only effectively absorb and buffer the impact of the outside world, but also enhance the buffer performance, improve the sealing of the cab, avoid scratches or damage caused by direct contact, extend the service life of the glass, and reduce maintenance costs.

[0013] (2) The buffer pads and baffles installed on the windshield can effectively absorb and disperse these vibration energies, reduce the direct impact of vibration on the windshield, and avoid glass fatigue damage caused by frequent vibration. The limiting blocks and limiting rods installed on the limiting seat ensure the stability and reliability of the windshield during movement, effectively limit the movement range of the glass, prevent the glass from falling off or shifting during movement, and ensure the safety of the cab.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: like Figures 1-3 , Figure 5 As shown, a movable windshield for a backhoe loader cab according to an embodiment of the present invention includes a windshield frame 1, with movable components 2 on both sides of the windshield frame 1. The movable components 2 include two movable rollers 201 on both sides of the windshield frame 1, with movable slide rails 202 in contact with the surfaces of the movable rollers 201. Five mounting screws 11 are connected to the movable slide rails 202, with a sealing gasket 12 connected to one end of each mounting screw 11. One side of the sealing gasket 12 contacts the backhoe loader cab (not shown in the figure) during actual use. The backhoe loader cab is connected to one end of the mounting screws 11, and one side of the sealing gasket 12 contacts the side of the movable slide rail 202. The side of the movable slide rail 202 is provided with two limit seats 203. The limit seats 203 are provided with limit grooves. The limit grooves are provided with limit blocks 9. One side of the limit block 9 is connected to a limit rod 10 through a bearing. One end of the limit rod 10 is connected to the limit seat 203. The limit seat 203 is fitted with a limit block 204. One side of the limit block 204 is connected to the side of the windshield frame 1.

[0019] Example 2: like Figure 1 , Figure 2 , Figure 4 As shown, a movable windshield for a loader cab according to an embodiment of the present invention includes a buffer assembly 3 on the windshield frame 1. The buffer assembly 3 includes a sealing block 301 on one side of the windshield frame 1, a movable slide rail 202 connected to a windshield fixing frame 302 at one end, a windshield 4 inside the windshield fixing frame 302 and the windshield frame 1, two handles 5 on one side of the windshield frame 1, four buffer pads 6 in contact with one side of the windshield 4, a baffle 7 on one side of the buffer pads 6, four fixing screws 8 connected to the baffle 7, and one end of the fixing screws 8 connected to the windshield fixing frame 302 and one side of the windshield frame 1. A sealing seat 303 is provided above the windshield fixing frame 302. The two sides of the sealing seat 303 are in contact with the sides of the sliding rail 202. Four shock absorbers 304 are provided inside the sealing seat 303. A buffer plate 305 is provided at one end of the shock absorber 304. One side of the buffer plate 305 and the inside of the sealing seat 303 are in contact with one side of the sealing block 301. The components 305 (buffer plate), 304 (shock absorber), 303 (sealing seat), 12 (sealing gasket), 8 (fixing screw), 6 (buffer pad), 5 (handle), 301 (sealing block), 202 (moving slide rail), and 201 (moving roller) are existing technologies and will not be described in detail in actual use. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0020] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0021] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to move the windshield, the driver can rotate the limiting rod 10, which can release the limiting block 9 set on the limiting rod 10 from the limiting block 204. Then, when the driver pulls the handle 5, the windshield frame 1 moves as a whole, driving the windshield 4 to move synchronously, realizing the adjustment of the field of vision or the opening of the cleaning window. Then, the windshield frame 1 slides smoothly along the sliding rail 202 through the moving rollers 201 set on both sides, so that the entire windshield 4 can be moved as needed. The rolling cooperation between the moving rollers 201 and the sliding rail 202 reduces frictional resistance and ensures easy and smooth operation. When the windshield frame 1 slides to a fixed position, the limiting block 204 is embedded in the limiting seat 203, which can constrain the windshield frame 1. At the same time, the limiting groove on the limiting seat 203 is provided with a limiting block 9. The limiting block 9 is connected to the limiting rod 10 through a bearing. The limiting rod 10 is fixed on the limiting seat 203, forming a rotatable but non-detachable limiting structure, thereby ensuring the degree of freedom of sliding while preventing the windshield frame 1 from accidentally leaving the track. When the equipment operates and generates vibration or impact, the sealing block 301 set in the windshield frame 1 moves with the windshield frame 1 and contacts the buffer plate 305. After the buffer plate 305 is subjected to force, it compresses the shock absorber 304. The shock absorber 304 completes energy absorption and release inside the sealing seat 303, effectively mitigating the vibration transmitted to the windshield 4. At the same time, the buffer pad 6 attached to the inner side of the windshield 4 is pressed between the windshield fixing frame 302 and the windshield frame 1 through the baffle 7 and the fixing screw 8, forming multi-point buffer support, further improving the vibration resistance. The movable slide rail 202 is fixed to the cab structure by mounting screws 11. The end of the mounting screw 11 is connected to a sealing gasket 12. The sealing gasket 12 is in close contact with the side of the movable slide rail 202 to prevent external dust and rainwater from entering the sliding area. The windshield fixing frame 302 is connected to the end of the movable slide rail 202, and a sealing seat 303 is set on it. The two sides of the sealing seat 303 are in contact with the side of the movable slide rail 202, and together with the sealing block 301, they form a closed buffer cavity to ensure the stable operation of the internal shock absorption structure.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
