For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] The embodiments of the present application will be described in detail below.

[0041] Referring to Figs. 1-3 The present application provides a crusher, which comprises a rotating roller 1, a bearing seat 2, a support 3, a protection device and the like.

[0042] The rotating roller 1 has crushing teeth, and is connected with the bearing seat 2 through bearings. The rotating roller 1 is driven by a driving motor.

[0043] The bearing seat 2 is movably mounted on the support 3.

[0044] The protection device comprises a connecting assembly 4, a state detection assembly 5 and a reset assembly 6.

[0045] The connecting assembly 4 is used to connect the support 3 and the bearing seat 2, and will be physically deformed, such as breaking or stretching, after being subjected to a predetermined size and direction of force (such as axial tension, radial shear force), so that the bearing seat 2 is movable, thereby changing the position of the rotating roller 1, and avoiding that a large volume of unbreakable hard objects are stuck or damage the working pair of crushing teeth.

[0046] The state detection assembly 5 is arranged on the moving path of the bearing seat 2, and is used to detect the position change of the bearing seat 2, or detect the physical deformation of the connecting assembly 4. In addition, the state detection assembly 5 is associated with the driving motor, and when the state detection assembly 5 detects the position change of the bearing seat 2 or the rotating roller 1, or detects the physical deformation such as breaking or stretching of the connecting assembly 4, the driving motor stops working, and the problem can be manually processed before restarting.

[0047] The reset assembly 6 and the connecting assembly 4 are arranged on the opposite sides of the bearing seat 2, and are used to reset the bearing seat 2 after removing the large volume of unbreakable hard objects.

[0048] Through the arrangement of the protection device, when a large volume of unbreakable hard objects are encountered, the working pair of the rotating roller 1 and the bearing seat 2 can move a distance under the reaction force of the hard objects, and at the same time, the state detection assembly 5 is used for detection, so as to facilitate troubleshooting according to the detection result.

[0049] The specific embodiments of the present application will be described below. Example 1

[0050] See Figs. 1-3 The bearing housing 2 is movably mounted on the bracket 3 in the following manner: the bracket 3 is bolted to the guide rail 31, and the bottom of the bearing housing 2 is slidably connected to the guide rail 31. When the crushing tooth encounters a large, unbreakable hard object, the bearing housing 2 is pushed back and moves along the guide rail 31.

[0051] In this embodiment, guide rails 31 are provided above and below the bearing housing 2 to enable the bearing housing 2 to move left and right more effectively. Example 2

[0052] See Figs. 1-3 In this embodiment, the connecting component 4 will break after being subjected to a predetermined radial shear force. Specifically, the connecting component 4 includes a pull ring 41, a connecting ring 42, and a breaking pin 43.

[0053] One end of the pull ring 41 has a laterally extending pull rod 411, which passes through the bracket 3 and is threadedly connected to a nut 412. For example... Fig. 1 As shown, the nut 412 prevents the pull rod 411 from moving to the left and disengaging from the bracket 3.

[0054] The connecting ring 42 is disposed on the bearing housing 2, and the pull ring 41 and the connecting ring 42 can be coaxial.

[0055] The break pin 43 passes through the pull ring 41 and the connecting ring 42, connecting the two together.

[0056] The reset assembly 6 includes a support base 61, a pivot pin 62, and a disc spring 63.

[0057] The support base 61 is fastened to the bracket 3 by bolts.

[0058] The shaft pin 62 and the break pin 43 are located on opposite sides of the bearing housing 2; one end of the shaft pin 62 is threaded to the bearing housing 2, and the other end is laterally slidably connected to the support seat 61.

[0059] A disc spring 63 is sleeved on the shaft pin 62 to keep the bearing seat 2 away from the support seat 61.

[0060] The working principle of the connecting component 4 and the reset component 6 is that when encountering a large, unbreakable hard object, the breaking pin 43 will break after being subjected to a predetermined radial shear force, and the bearing seat 2 can move to the left; after the hard object is removed, the bearing seat 2 can move to the right and reset under the reset force of the disc spring 63.

[0061] It should be noted that the disc spring 63 is a type of elastic element, but other elastic elements can also be used.

[0062] In order to quickly return to the initial position under the action of the disc spring 63 after the bearing seat 2 moves left, the bracket 3 is threadedly connected with a limiting piece 32, and when the pull ring 41 and the connecting ring 42 are coaxial, the left end of the limiting piece 32 can be in contact with the right side of the bearing seat 2. Embodiment 3

[0063] Referring to Figs. 1-3 In the embodiment, the state detection assembly 5 comprises a position sensing switch for detecting whether the bearing seat 2 is at a specified position, the bearing seat 2 can pass through the specified position when moving, and the output end of the position sensing switch is electrically connected with the control end of the driving motor. In this way, when the crushing teeth encounter a large hard unbreakable object, the bearing seat 2 is pulled to break the connecting assembly 4 after passing through the specified position, triggering the position sensing switch, and the position sensing switch feeds back the detection data to the control cabinet matched with the crusher, and the control cabinet makes the driving motor stop working in time to protect the driving motor and the crushing teeth. Embodiment 4

[0064] Referring to Figs. 1-3 In the embodiment, the position sensing switch is electrically connected with an alarm (not shown in the figure), and timely warning is realized in the sound and light mode.

[0065] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, for the person skilled in the art, the utility model can have various changes and changes, in the case of no conflict, the embodiments of the application and the features in the embodiments can be combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
