[0002] When the crusher is crushing sand and gravel, a small amount of debris will burst out from the feed port. In order to avoid the damage to the workers caused by the debris, it is necessary to set a shield plate at the feed port to block the bursting debris. The existing shield plate needs to be manually pulled outwards when in use, and then the position of the shield plate is fixed by bolts. After the feeding is completed, the bolts are removed to reset the shield plate to block the feed port.

[0003] For example, CN218013031 U discloses an anti-splashing crusher, which belongs to the technical field of crushers; an anti-splashing crusher comprises: a crusher case, a feed bin for feeding and a shielding mechanism, the shielding mechanism comprises two shielding plates which are symmetrically arranged and located on both sides of the interior of the crusher case, the shielding plates are slidably connected to the crusher case, and pulling parts are provided on the tops of both sides of the crusher case, the pulling parts comprise two sliding rods which horizontally penetrate the crusher case and extend into the interior thereof and are fixedly connected to the shielding plates, the sliding rods are slidably connected to the crusher case, a pulling plate is fixedly connected to one end of the sliding rods away from the shielding plates, a slot is penetrated through the top of the crusher case, and the feed bin is fixedly connected to the top of the crusher case; by arranging the shielding mechanism and the protective plate, it is possible to effectively prevent sand and gravel aggregates from splashing out from the slot or the feed bin when being crushed in the crusher case, thereby effectively preventing workers from being injured by the splashing sand and gravel debris.

[0004] Based on the above, the existing crusher needs to be stopped first to add sand and gravel into the crusher, and then the position of the baffle plate can be adjusted before the crusher can be started, which wastes a lot of time, affects the crushing efficiency of sand and gravel, and affects the working efficiency of the crusher. In addition, the baffle plate needs to be manually adjusted every time material is added, which results in a heavy labor burden on the staff and poor use effect. Utility Model Content
