Description

Technical Field

[0001] The utility model relates to the technical field of rotor conveying shaft structures, and particularly relates to a rotor feeder facilitating blade replacement. Background Art

[0002] Rotor feeders are often used in industrial production. They have the function of uniformly conveying materials, and can convey a wide variety of materials, including cement, coal blocks, barley, etc. This also results in relatively large wear on the rotor conveying shafts of rotor feeders, and the wear conditions of the blades on the rotor conveying shafts vary. Most of the existing conveying shafts of rotor feeders are integrally designed. When individual blades are severely worn and cannot be used, only the method of replacing the entire conveying shaft can be chosen to replace the blades. The limitation of updating the blades of the conveying shaft is relatively large, which causes unnecessary waste and increases the production cost of enterprises. Content of the Utility Model

[0003] Aiming at the defect that the limitation of updating the blades of the conveying shaft of the existing rotor feeder is large, resulting in waste and increasing the production cost of enterprises, the utility model provides a rotor feeder facilitating blade replacement, which can singly replace the blades of the conveying shaft of the rotor feeder, with relatively small limitations, and saves the production cost for enterprises.

[0004] The utility model provides the following technical solutions:

[0005] It includes a feed bin, and bearing mouths are symmetrically arranged on both sides of the feed bin. It is characterized in that: near the bearing mouths, a rotor conveying shaft with replaceable blades is arranged inside the feed bin.

[0006] It is further characterized in that:

[0007] Blade slots are evenly opened on the rotor conveying shaft, and the rotor blades are inserted into the blade slots and closely fit with the rotor conveying shaft. A main bearing is arranged outside the grooved end of the rotor conveying shaft, and a number of blade stoppers are evenly distributed on the main bearing. The main bearing is inserted into the blade slots of the rotor conveying shaft through the blade stoppers and is threadedly connected with the rotor conveying shaft. The blade stoppers have the function of fixing the rotor blades. A connecting bearing is arranged outside the other end of the rotor conveying shaft, and the rotor conveying shaft is threadedly connected with the connecting bearing through bolts;

[0008] A motor bearing is arranged inside the bearing mouth on the left side of the feed bin. The motor bearing is threadedly connected with the main bearing through bolts. A fixed bearing seat is arranged near the bearing mouth on the right side of the feed bin. The fixed bearing of the fixed bearing seat is inserted into the bearing mouth and is connected with the connecting bearing through bolts;

[0009] The end of the extending motor shaft of the rotor motor is fixedly connected with the motor bearing, and the rotor motor is arranged on the left side of the feed bin.

[0010] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0011] By providing blade slots on the rotor conveying shaft, the rotor blades can be inserted and installed. In the case of different degrees of blade wear, only the blades that can no longer be used need to be replaced, which is very convenient, saves the consumption of the conveying shaft, and is conducive to reducing the production cost of the enterprise.

[0012] Blade stoppers are provided on the main bearing to ensure the stability of the rotor blades during rotation. It has a fixing effect on the rotor blades. On the other hand, the main bearing has connectability. By connecting the main bearing to the motor bearing, the rotation of the rotor motor drives the stable rotation of the rotor conveying shaft.

[0013] The connecting bearing enables the other end of the rotor conveying shaft to be stably connected to the fixed bearing seat, allowing the rotor conveying shaft to rotate stably and evenly inside the feed bin, which is beneficial to the production of the enterprise.
