[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0022] like Figure 1-Figure 5 As shown, a protective device of an embodiment of the utility model comprises a first protective member 1, a second protective member 2 and a driving member 3. The second protective member 2 is mounted on the first protective member 1 and can slide in the up and down direction relative to the first protective member 1. The second protective member 2 has a first position 41 and a second position 42. When the second protective member 2 is located at the first position 41, at least part of the second protective member 2 and at least part of the first protective member 1 are in an overlapping state. When the second protective member 2 is located at the second position 42, the second protective member 2 and the first protective member 1 are in an unfolded state.

[0023] The driving member 3 is connected to the second protection member 2 to drive the second protection member 2 to move between the first position 41 and the second position 42. Specifically, the driving member 3 is an electric hydraulic push rod.

[0024] A protective device of an embodiment of the utility model, during the operation of the crusher, the first protective member 1 and the second protective member 2 are in a stacked state to save space. During the maintenance of the crusher, the first protective member 1 is driven by the driving member 3 to move from the first position 41 to the second position 42, so that the first protective member 1 and the second protective member 2 are in an unfolded state, so as to produce obvious physical isolation between the maintenance personnel and the crushing drum of the crusher to ensure the life safety of the maintenance personnel. The utility model is simple to operate and easy to use, and has a simple structure, saves costs and is highly practical.

[0025] In some embodiments, a slide 11 is provided on the first guard member 1, and the slide 11 extends in the up and down directions. A first slider 21 is provided on the second guard member 2, and the first slider 21 is slidably installed in the slide 11 and is not easily detached from the slide 11, so that the second guard member 2 can move on the first guard member 1 along the extension direction of the slide 11, thereby realizing the overlapping and unfolding of the second guard member 2 and the first guard member 1. Moreover, the matching method of the second guard member 2 and the first guard member 1 is simple and easy to operate.

[0026] In some embodiments, there are two slideways 11, which are arranged at intervals along a first direction on the first protection member 1, and the first direction is orthogonal to the up-down direction. There are two first sliders 21, which are arranged at intervals on the second protection member 2, and the two first sliders 21 correspond to the two slideways 11 one by one.

[0027] Specifically, there are two slideways 11 and two first sliders 21, and the two first sliders 21 correspond one to one with the two slideways 11, which improves the fit between the second guard 2 and the first guard 1, makes the second guard 2 and the first guard 1 more firmly connected, and also makes the second guard 2 more stable when moving in the up and down directions relative to the first guard 1.

[0028] In some embodiments, the slide 11 is formed on one side surface of the first guard 1, and the slide 11 is formed by being recessed from one side surface of the first guard 1 toward the other side surface of the first guard 1. The one side surface of the first guard 1 and the other side surface of the first guard 1 are arranged relative to each other, so that the upper and lower ends of the slide 11 are in a closed state, so that the first slider 21 is not easy to detach from the two ends of the slide 11 when moving on the slide 11. Moreover, the recessed formation of the slide 11 also reduces the gap between the second guard 2 and the first guard 1, thereby improving the fit between the second guard 2 and the first guard 1.

[0029] In some embodiments, the first sliding block 21 is located at the upper end of the second protective member 2 .

[0030] Specifically, when the first slider 21 is located at the upper end of the slideway 11 , the second guard 2 and the first guard 1 are in a stacked state, and when the first slider 21 is located at the lower end of the slideway 11 , the second guard 2 and the first guard 1 are in an unfolded state.

[0031] In some embodiments, a protective device further includes a slide rail 5 extending in the up-down direction. A second slider 12 is provided on the first protective member 1 . The second slider 12 is slidably installed in the slide rail 5 and is not easily detached from the slide rail 5 .

[0032] Specifically, the driving member 3 drives the second guard member 2 to move downward relative to the first guard member 1, so that the first slider 21 is located at the lower end of the slideway 11. At this time, the driving member 3 continues to drive the second guard member 2 to move downward, which will drive the first guard member 1 to move downward along the extension direction of the slide rail 5, so that the protective device is in an expanded state, isolating the maintenance personnel from the crushing drum of the crusher, and ensuring the life safety of the maintenance personnel.

[0033] Specifically, the driving member 3 drives the second guard member 2 to move upward relative to the first guard member 1, so that the first slider 21 is located at the upper end of the slideway 11. At this time, the driving member 3 continues to drive the second guard member 2 to move upward, which will drive the first guard member 1 to move upward along the extension direction of the slide rail 5, so that the protective device is in a stacked state, which not only saves placement space, but also does not affect the normal use of the crusher.

[0034] Specifically, the upper and lower ends of the slide rail 5 are in a closed state, so that when the first protective member 1 slides in the slide rail 5 through the second slider 12, it is not easy to detach from the two ends of the slide rail 5, so that the first protective member 1 is firmly installed on the slide rail 5, and the matching method is simple and the operation is convenient.

[0035] In some embodiments, there are two slide rails 5, and the two slide rails 5 are arranged at intervals along a first direction, the first direction is orthogonal to the up and down direction, the first protective member 1 is arranged between the two slide rails 5, and there are two second sliders 12, and the two second sliders 12 are arranged at intervals along the first direction on the first protective member 1, and the two second sliders 12 correspond one-to-one to the two slide rails 5.

[0036] Specifically, there are two slide rails 5 and two second sliders 12 , and the two second sliders 12 correspond to the two slide rails 5 one by one, which improves the fit between the first guard 1 and the slide rail 5 and makes the first guard 1 more stable when moving on the slide rail 5 .

[0037] In some embodiments, the driving member 3 is connected to the lower end of the second protective member 2, so that when the second protective member 2 and the first protective member 1 are in a stacked state, the overall size of the protective device is as small as possible to save space.
