In view of this, in order to solve the above-mentioned problems, the impact plate 2 and the positioning hook 3 are added on this basis.

[0026] Further:

[0027] As Figure 1 - Figure 5 As shown in the figure:

[0028] In combination with the above content: further comprising an impact plate 2, a positioning hook 3, a pull block 4, a tension plate 5, a sliding rod 6, a spring 7, a positioning block 8, a moving protective net 9, a guide rod 10, a positioning protective net 11, a protective net groove 12 and a connecting hole 13 arranged on one side of the driver's cabin 1;

[0029] The surface of the cockpit 1 is slidingly connected with the positioning hook 3 fixedly installed with the impact plate 2, one end of the positioning hook 3 is slidingly connected with the pulling block 4 fixedly connected with the pulling plate 5, and the other side surface of the pulling plate 5 is further fixedly connected with one end of the sliding rod 6, the surface of the sliding rod 6 is further sleeved with the spring 7, both ends of the spring 7 are respectively fixedly connected with the pulling plate 5 and the surface of the cockpit 1, the sliding rod 6 further penetrates through the cockpit 1 and is slidingly connected with the cockpit 1, the sliding rod 6 is further fixedly connected with the positioning block 8, the positioning block 8 is abuttingly connected with the inner surface of the cockpit 1, one side of the positioning block 8 is further fixedly installed with the moving protective net 9, the surface of the positioning block 8 is further slidingly connected with the guide rod 10 fixedly installed on the inner surface of the cockpit 1, the other end of the guide rod 10 is fixedly connected on the surface of the positioning protective net 11, and the positioning protective net 11 is fixedly installed on the surface of the cockpit 1, the inner side top of the cockpit 1 is further provided with the protective net slot 12 slidingly connected with the moving protective net 9 and the connecting hole 13 slidingly connected with the guide rod 10.

[0030] In the embodiment, when the cockpit 1 is impacted during operation, the impact plate 2 will also be impacted to a certain extent, at this time, the impact plate 2 will exert momentum on the positioning hook 3, at this time, the positioning hook 3 will slide between the cockpit 1 and the pulling block 4 and be separated from the pulling block 4, at this time, the spring 7 in the stretched state will exert upward thrust on the pulling block 4 and the sliding rod 6 through the pulling plate 5, the sliding rod 6 will push the positioning block 8 and the moving protective net 9 to slide along the guide rod 10 and pop in the direction of the protective net slot 12 and the connecting hole 13, at the same time, the moving protective net 9 and the positioning protective net 11 are no longer overlapped, and the two will shield the front windshield, and avoid the impact object from entering the inside of the cockpit 1 to affect the staff.

[0031] Further, in the embodiment:

[0032] In an optional embodiment, the impact plate 2 is arranged in front of the cockpit 1, and the distance between the impact plate 2 and the cockpit 1 is greater than the length of the end of the positioning hook 3.

[0033] In the embodiment, the impact plate 2 arranged in front of the cockpit 1 can be preferentially impacted by external force, thereby separating the positioning hook 3 from the pulling block 4.

[0034] Further, in the embodiment:

[0035] In an optional embodiment, the end of the positioning hook 3 is in the shape of “J”, and the surface of the pulling block 4 is provided with a through hole matched with the positioning hook 3.

[0036] In the embodiment, the end of the positioning hook 3 in the shape of “J” can be smoothly separated from the pulling block 4 after being impacted by the momentum of the impact plate 2, thereby driving the moving protective net 9 to rise under the stretching of the spring 7.

[0037] Further more:

[0038] In an alternative embodiment, the tension plate 5, the slide bar 6 and the spring 7 are equidistantly arranged on the inner surface of the cockpit 1.

[0039] In this embodiment, the tension plate 5, the slide bar 6 and the spring 7 equidistantly arranged inside the cockpit 1 can make the upward movement of the mobile protective screen 9 more stable, and provide certain guarantee for the protection work.

[0040] Further more:

[0041] In an alternative embodiment, the mobile protective screen 9 and the positioning protective screen 11 are of the same shape, and the height of the mobile protective screen 9 and the positioning protective screen 11 accounts for one half of the front windshield of the cockpit 1.

[0042] In this embodiment, when the mobile protective screen 9 is not lifted, the overlapped mobile protective screen 9 and the positioning protective screen 11 can provide an effective view for the operator, and after the mobile protective screen 9 is lifted, the mobile protective screen 9 and the positioning protective screen 11 can block the windshield, so as to avoid secondary injury to the operator after the windshield is broken by impact, and also avoid the impact object entering the cockpit 1.

[0043] Further more:

[0044] In an alternative embodiment, the surface of the positioning protective screen 11 is provided with a through hole matched with the guide rod 10.

[0045] In this embodiment, the through hole provided on the surface of the positioning protective screen 11 can make the guide rod 10 and the mobile protective screen 9 stably lift, so as to effectively shield the front windshield by the mobile protective screen 9, and avoid the injury to the operator from the outside.

[0046] The working principle and use process of the utility model: when the cockpit 1 is impacted during operation, the impact plate 2 will also be impacted, at this time, the impact plate 2 will apply momentum to the positioning hook 3, at this time, the positioning hook 3 will slide between the cockpit 1 and the pull block 4 and be separated from the pull block 4, at this time, the spring 7 in the stretched state will generate upward thrust on the pull block 4 and the slide bar 6 through the tension plate 5, and the slide bar 6 will push the positioning block 8 and the mobile protective screen 9 to slide along the guide rod 10 and pop towards the direction of the protective screen groove 12 and the connecting hole 13, at the same time, the mobile protective screen 9 and the positioning protective screen 11 are no longer overlapped, and the two will shield the front windshield, and avoid the impact object entering the inside of the cockpit 1 to affect the operator.

[0047] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
