DETAILED DESCRIPTION
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] Example:
[0023] Reference Figure 1 - Figure 4 The utility model discloses a desktop stone crusher, comprising a casing 1, a discharge port 2 is provided at the bottom of the casing 1, a feed port 3 is provided on one side of the upper end of the casing 1, and a slide plate 4 is provided on the inner wall of the casing 1 near the feed port 3, a stone crushing rotor 5 is provided inside the casing 1, and the inclination direction of the slide plate 4 is toward the direction of the stone crushing rotor 5, a protective baffle 6 is provided at the position of the feed port 3 inside the casing 1, and an arc baffle 7 is provided on the bottom side of the slide plate 4, and a linkage mechanism 8 is provided on the outer wall of the casing 1.
[0024] In this embodiment, when stones are put into the device from the feed port 3, the stones slide downward along the direction of the slide plate 4 and lift up the protective baffle 6. When the protective baffle 6 is lifted up, the arc baffle 7 is raised by the linkage mechanism 8, so that the arc baffle 7 blocks the position where the stones are lifted up, avoiding the effect of stones being discharged through the gaps in the protective baffle 6, and effectively preventing the stones from splashing into the device and causing harm to workers. After the stones enter, the protective baffle 6 flips downward under the action of gravity. At this time, the arc baffle 7 follows the protective baffle 6 to fall downward, resetting the arc baffle 7 and causing the stones to continue to move downward in the direction of the slide plate 4, and the stones are crushed by the stone crushing rotor 5.
[0025] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the protective baffle 6 includes a fixed shaft 61 and a metal plate 62. The fixed shaft 61 is located above the inside of the feed port 3 and is rotatably connected to the inner wall of the casing 1. The bottom of the fixed shaft 61 is connected to the metal plate 62, and both sides of the metal plate 62 are in contact with the inner wall of the casing 1.
[0026] In this embodiment, when the device is in use, since the fixed shaft 61 is rotatably connected to the casing 1, and the metal plate 62 is connected to the fixed shaft 61, when the metal plate 62 is not subjected to thrust, it will be perpendicular to the horizontal plane under the action of gravity. When no stones enter the device, the metal plate 62 will block the feed port 3 to prevent stones from flying out and injuring workers.
[0027] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the arc-shaped baffle 7 includes a metal rod 71, and the metal rod 71 is rotatably connected to the rotating shaft of the stone crushing rotor 5. A sliding baffle 72 is provided at one end of the metal rod 71 away from the rotating shaft.
[0028] In this embodiment, the metal rod 71 is used to install the sliding baffle 72, and the metal rod 71 is rotated to guide the sliding baffle 72, so that the sliding baffle 72 rises along the rotation direction of the crushing rotor 5, thereby preventing the crushing rotor 5 from knocking stones away, thereby preventing the stones from flying out along the slide plate 4.
[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the linkage mechanism 8 includes a first connecting shaft 81 and a second connecting shaft 82 , the first connecting shaft 81 is fixedly connected to the fixed shaft 61 , the second connecting shaft 82 is rotationally connected to the rotating shaft, and is fixedly connected to the metal rod 71 .
[0030] In this embodiment, the first connecting shaft 81 and the second connecting shaft 82 are provided to extend the rotation axes of the fixed shaft 61 and the metal rod 71 , and the rotation axes of the fixed shaft 61 and the metal rod 71 are extended to the outside of the housing 1 .
[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a bending connecting rod 83 is fixedly installed on the circumferential side of the first connecting shaft 81 , and a guiding connecting rod 84 is fixedly installed on the circumferential side of the second connecting shaft 82 .
[0032] In this embodiment, through the setting of the bending connecting rod 83, when the metal plate 62 is pushed by the stone and rotates, the bending connecting rod 83 fixed to the fixed shaft 61 by the first connecting shaft 81 pushes the guide connecting rod 84 to move upward, so that when the protective baffle 6 is pushed to rotate upward, the arc baffle 7 also moves upward synchronously, thereby achieving the effect of preventing the stone from popping out.
[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, one end of the bending link 83 away from the first connecting shaft 81 is rotatably connected to a slider 85 , a sliding guide rail 86 is provided on one side of the guide link 84 , and the slider 85 is inserted into the interior of the sliding guide rail 86 .
[0034] In this embodiment, by inserting the slider 85 into the sliding guide rail 86, the guide link 84 and the bending link 83 are always in contact with each other, so as to facilitate the mutual linkage of the protective baffle 6 and the arc baffle 7, and prevent the protective baffle 6 and the arc baffle 7 from being misaligned, resulting in the stone being unable to contact the crushing rotor 5.
[0035] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
