Description

Technical Field

[0001] The utility model relates to the technical field of anti-splashing of crushers, in particular to an anti-splashing force-dissipating device for ore feeding of a jaw crusher. Background Art

[0002] Jaw crusher is a kind of crushing equipment, which mainly consists of two jaw plates, the movable jaw and the fixed jaw, to form a crushing chamber, simulating the movement of the two jaws of animals to complete the material crushing operation. This type of crusher can be divided into PE series and PEX series. PE series jaw crusher is suitable for coarse crushing or primary crushing because of its large feed particle size. The PEX series is more suitable for fine crushing or secondary crushing; the working principle of the jaw crusher is that the movable jaw plate makes periodic reciprocating motion on the fixed jaw plate, sometimes approaching and sometimes leaving. When approaching, the material is squeezed, split, and impacted between the two jaw plates and crushed; when leaving, the crushed material is discharged from the discharge port by gravity. The discharge port of this crusher has a wide adjustment range to meet the requirements of different users.

[0003] After searching, it was found that the Chinese patent publication number CN216172569U disclosed a "splash-proof jaw crusher", which includes an outer box body, a crushing assembly is arranged inside the outer box body, and a power assembly connected to the crushing assembly is arranged on the outer wall of the outer box body;

[0004] The importance of inlet splash protection in the crushing process cannot be ignored. If it cannot effectively dissipate force, it will bring a series of safety hazards and environmental problems. First, the material may splash out of the inlet at high speed, directly threatening the safety of the operator. The splashing material may cause injury to the operator and may even cause more serious safety accidents. Secondly, the splashing material may also cause impact on other parts of the crusher, accelerate equipment wear, shorten the service life of the equipment, and may increase the maintenance cost of the equipment. In addition, the splashing of materials may also cause dust pollution, pose a threat to the health of the operator, and may have long-term effects on the environment. If the material contains harmful substances, this pollution will be more serious. Therefore, the inlet splash protection device plays a vital role in the crushing process, and it must be ensured that it can effectively dissipate force to ensure the safety of the operator, the normal operation of the equipment, and the health of the environment.
