Description

Technical Field

[0001] The utility model belongs to the technical field of crushing devices, in particular to a crushing device with a protective structure. Background Art

[0002] Phosphate rock is a phosphorus-containing ore, mostly found in sedimentary rocks, but also in metamorphic rocks and igneous rocks. Except for some individual cases, the phosphorus in the mineral always exists in the form of orthophosphate. The main mineral of phosphorus is apatite. Phosphorus is an important chemical raw material and an essential element for the growth of crops. Industrial phosphorus must be extracted from phosphate rock in large quantities for the manufacture of yellow phosphorus, red phosphorus, phosphoric acid, phosphate fertilizers, and phosphates. In the mining of phosphate rock, the mined phosphate rock is crushed to facilitate its transportation.

[0003] A Chinese patent discloses a crushing device for phosphate rock processing (CN218393843U), comprising a feed mechanism and a receiving mechanism. A buffer mechanism for reducing impact is provided in the inner middle portion of the feed mechanism. The receiving mechanism for receiving material is provided in the lower middle portion of the buffer mechanism, and a receiving mechanism for discharging material is provided below the receiving mechanism. A stabilizing mechanism for stabilizing the material is installed in the outer middle portion of the feed mechanism. Compared with existing devices, this crushing device for phosphate rock processing uses a feed frame and a first motor to drive a conveyor belt and a limit plate to rotate, thereby lifting material at the bottom to the feed port and working box for processing. This reduces the labor of workers loading materials during operation and is conducive to improving processing efficiency. The limit plate can prevent material from falling when it is lifted upward. The third motor can use the rotating shaft to drive the receiving plate to flip, thereby closing it during the bottom material transfer process. Most of the current crushing devices do not have a protective mechanism, so gravel will splash during the crushing of phosphate rock. The gravel can easily cause certain dangers during the splashing process, thereby reducing the safety of the crushing device. For this purpose, a crushing device with a protective structure is provided. Utility Model Content

The phosphate rock is crushed under the action of the first crushing roller 7 and the second crushing roller 8. When the first crushing roller 7 rotates, it will drive the positioning rod 12 to rotate. At this time, the positioning rod 12 will drive the rotating disc 69 to rotate. As the rotating disc 69 rotates, the connecting rod 68 drives the piston plate 66 to move up and down in the piston box 61 through the mounting clip 67. Water is sucked into the piston box 61 through the water inlet pipe 65, and then is transported into the spray pipe 64 through the water outlet pipe 62, and then sprayed around the machine body 1.
