Abstract
The invention discloses a shear type self-sucking pump. The shear type self-sucking pump comprises a pump body, a pump cover, a middle body, a motor, an impeller and a material guide mechanism. A work cavity is arranged in the pump body. The pump is provided with a feed inlet, a discharge outlet and an installation opening which communicate with the work cavity. Fixed blades are arranged in a runner of the feed inlet. The pump cover is located at the installation opening and fixed between the pump body and the middle body through the middle body. The motor is connected to the side, far away from the pump cover, of the middle body. An output shaft of the motor extends into the work cavity. The impeller is located in the work cavity and installed on the output shaft. One end of the material guide mechanism extends into the work cavity from the feed inlet and is in transmission connection with the output shaft. The material guide mechanism comprises a transmission shaft, a material guide wheel and movable blades. The movable blades are located in the runner of the feed inlet. In addition, in the rotation process of the output shaft, the movable blades and the fixed blades are mutually matched to shear materials at the feed inlet. According to the shear type self-sucking pump, the phenomenon that fibers wind around the output shaft or the impeller can be effectively avoided, and accordingly discharge of the materials is smoother.
