Raw material crushing device for soil remediation agent

The invention discloses a raw material crushing device for a soil remediation agent, and particularly relates to the field of soil remediation agents. The raw material crushing device comprises a processing table, a crushing barrel is arranged on one side of the upper surface of the processing table, an automatic feeding assembly is fixedly installed on the side wall of the crushing barrel, the upper surface of the crushing barrel communicates with a feeding pipe, and the center of the lower surface of the crushing barrel communicates with a discharging pipe. Through the arrangement of the first limiting sliding groove, the hydraulic rod and the first limiting plate, when the filter screen is blocked, the hydraulic rod is started to work, then the hydraulic rod drives the first limiting plate to move from top to bottom, and the filter screen is connected with the input end of the hydraulic rod through the first limiting plate, so that the filter screen is not blocked; the first limiting plate moves to drive t
