Example (b):

referring to the embodiment shown in fig. 1-2, the jaw crusher feed inlet protection device includes a protection device 2 disposed at one side of a feed inlet of a jaw crusher body 1 close to a static jaw plate, the protection device 2 is disposed at the feed inlet above the jaw crusher body 1 and close to one side of the static jaw plate, the protection device 2 is used for protecting a plate above the static jaw plate, the protection device 2 includes a wear-resistant guard plate 21 disposed above the jaw crusher body 1, the wear-resistant guard plate 21 is a heat-treated steel plate, but a wear-resistant layer is further disposed above the wear-resistant guard plate to increase strength and wear resistance of the wear-resistant guard plate, the wear-resistant guard plate 21 is inclined, a lower end of the wear-resistant guard plate 21 is close to the feed inlet of the jaw crusher body 1, the inclined wear-resistant guard plate 21 enables a material falling above the wear-resistant guard plate to slide to the feed inlet of the jaw crusher, a bracket 25 is fixedly disposed on the jaw crusher body 1, and the guard plate 21 is connected with the bracket 25 through a bolt 22, the wear-resistant guard plate 21 connected by the bolts 22 can achieve the purpose of convenient replacement.

Wear-resisting backplate 21 below is equipped with buffer gear, buffer gear locates powerful spring 23 on bolt 22 including the cover, and powerful spring 23 is located between wear-resisting backplate 21 and the support 25, can dismantle on the support 25 and be connected with spring steel plate 24, and spring steel plate 24 is located between support 25 and the wear-resisting backplate 21, spring steel plate 24 is several words form, and spring steel plate 24 evenly distributed is on support 25, powerful spring 23 and spring steel plate 24's existence, can be when strikeing the effort and act on it, can make it take place elastic deformation in order to offset or reduce this impact effort, reach the purpose of protection the device and wear-resisting backplate 21.
