[0003] At present, the patent with the patent number "CN205502111U" discloses a tunnel excavating loader with a static pressure closed cab, which comprises a machine body and a cab installed on the machine body. The cab is a closed cab, which comprises a closed main frame. The front of the main frame is provided with a falling object protection structure. The side edges of the front and side of the main frame are provided with left and right rearview mirrors. It has the advantages of good moisture-proof effect, comfortable working environment, small harm to the operator's body, high safety, etc.

[0004] In addition, the patent with the patent number "CN215759290U" discloses a falling object prevention cab, which solves the defects of poor falling object prevention ability of the ceiling of the loader in the tunnel and mine and the lack of anti-rollover and rolling function. It mainly comprises a ceiling and a stand. The ceiling is an arch structure. The ceiling is connected with the stand through a ceiling frame. The support frame is provided with an anti-toppling rear frame.

[0005] In summary, in view of the defects of the above-mentioned comparative documents and in combination with the existing mature technology, the following defects exist:

[0006] 1. The dipper arm of the loader is the main structure for mounting the dipper on the loader. It is an arm that can move up and down and tilt. It plays a role in carrying and controlling the dipper during loading and unloading of materials. When the dipper arm is used to scoop up materials, the scooped materials may fall off. At this time, the materials may hit the front glass of the cab. If the materials are large or heavy, the glass may be broken or damaged, which may cause harm to the driver.

[0007] 2. During the loading process of the driver using the dipper arm, a large amount of dust will adhere to the front glass of the cab.

[0048] The complete working principle of the above embodiment is as follows:

[0049] Firstly, the operator drives the hydraulic rod to drive the loading arm 13 to lift the material and rotate, at this time, the side of the loading arm 13 away from the support plate 14 rises, so that the side of the loading arm 13 close to the support plate 14 descends, at this time, the loading arm 13 drives the driving gear 204 to rotate, the driving gear 204 drives the meshing connected driven gear 203 to rotate, the driven gear 203 drives the rotating roller 201 to rotate counterclockwise, at this time, the rotating roller 201 rotates to wind the connecting line 202, so that the connecting line 202 is pulled, when the connecting line 202 is pulled by the rotating roller 201, the end of the connecting line 202 away from the rotating roller 201 will pull the sliding block 209, so that the sliding block 209 is pulled upward by the rotating roller 201, at this time, the sliding block 209 compresses the reset spring 208 in the inside of the sliding groove 206 while sliding upward, and when the sliding block 209 moves, it will drive the fixed guide rail 211 to move upward, when the guide rail 211 moves, the limiting plate 212 in the inside of the guide rail 211 always slides on the inner wall of the sliding groove 206 under the action of the elastic force of the pressure spring 213, so that the sliding block 209 always keeps moving slowly and stably, when the sliding block 209 moves, it will also drive the fixed clamping plate 214 to move upward, the clamping plate 214 moves upward to the top of the front side of the support plate 14, at this time, the end of the loading arm 13 away from the support plate 14 also scoops up the material to move to a higher place, at this time, if the material falls, it will be blocked by the clamping plate 214, avoiding the material scooped up by the loading arm 13 from falling directly on the front end of the support plate 14, thereby avoiding the front glass of the support plate 14 from being broken by the material, reducing the economic loss, and the protection glass can keep clean and transparent, ensuring that the driver has a clear view, the driver can better observe the work area, the road and the obstacles, improve the safety and operation efficiency, and ensure the safety of the driver.

[0050] Further, when the card plate 214 moves upward, the fixed hollow plate 31 is driven to move, and the hollow plate 31 drives the sliding rod 34 connected to the inside to move. Since the front end of the glass of the support plate 14 is usually arc-shaped, the buffer spring 33 is in a compressed state at this time, so that when the sliding rod 34 moves upward with the hollow plate 31, the sliding rod 34 in the compressed state slides to the outside of the hollow plate 31 under the action of the elastic force of the buffer spring 33, and the end of the sliding rod 34 away from the hollow plate 31 moves to the direction close to the front end glass of the support plate 14. When the sliding rod 34 moves, the telescopic rod two 35 is driven to move, and the connecting block 38 rotationally connected to the telescopic rod two 35 is driven to move, so that the connecting block 38 moves to the direction close to the front end glass of the support plate 14, and the connecting block 38 is always attached to the surface of the glass. At this time, the cloth on the surface of the connecting block 38 can wipe the front end glass of the support plate 14, so that the front glass does not attach dust, and the driver can obtain a clearer view, more accurately observe the work area and the surrounding environment, improve the accuracy and safety of operation, and the glass keeps clean, so that the driver does not need to clean the glass to restore the view, can focus more on the operation of the loader and complete the task, improve the work efficiency, the dust does not adhere to the glass, the driver can better see the obstacles and pedestrians in front, reduce the risk of accidents, and the connecting block 38 wipes the front glass while preventing the falling of materials by the card plate 214, without adding additional driving equipment, simplifying the operation and installation process, reducing the cost and the complexity of maintenance, and reducing the time and workload of the driver for cleaning the glass, improving the work efficiency, and further reducing the frequency of manual cleaning of the glass, saving the cleaning cost.
