[0002] In the production process of plastic hoses, the first step is to pour the raw materials into the hopper of the extruder. The opening of the hopper is relatively high above, so a plastic hose raw material loader is required to feed the material into the hopper. The application number "CN202120851114.2" proposes a plastic tube raw material feeding device with convenient feeding. The cover device is provided with a push-type storage container. When the raw materials in the storage container are used up, the extraction pipe can be lifted up, the storage container can be pushed out, and then the storage container can be filled with raw materials, and then the storage container can be pushed back under the extraction pipe. In use, it was found that the spiral blades of the spiral extraction machine used in the device would stir the raw materials, causing the raw material powder to fly and the dust to be large. In addition, the lifting mechanism of the extraction pipe is not limited, and the lifting efficiency of the extraction pipe is low. Utility Model Content
