Description

Technical Field

[0001] The utility model belongs to the technical field of conveyors, in particular to a novel screw conveyor. Background Art

[0002] A screw conveyor uses a power source to rotate a spiral mandrel. The principle of the spiral propels the mandrel forward or backward as it rotates is used to move materials along with it, enabling long-distance mechanical conveying of materials. Screw conveyors offer advantages such as a simple mechanical structure, low cost, reliable and stable operation, low noise, low maintenance costs, and the ability to extend conveying distances.

[0003] When workers use a screw conveyor to transport coal, the screw conveyor is prone to blockage. At this time, the conveyor needs to be stopped and manually unblocked, which reduces the conveying efficiency of the conveyor. Moreover, when the screw conveyor is blocked, the motor is still operating normally, which will cause damage to the motor and shorten the service life of the motor. Utility Model Content

[0004] The purpose of this utility model is to provide a novel screw conveyor in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A new type of screw conveyor includes a support frame and a conveying cylinder arranged on the support frame. A feed port arranged on one side of the conveying cylinder is connected to a spiral component placed in the conveying cylinder. The spiral component includes a central shaft and spiral blades arranged on the central shaft. A universal shaft fixed at one end below the central shaft is located in the conveying cylinder. A driving motor is fixed on the outside of the lower end of the conveying cylinder. The rotating shaft of the driving motor passes through the bottom wall of the conveying cylinder and is fixedly connected to the universal shaft. One end of the spiral component extends out of the discharge port at the upper end of the conveying cylinder.

[0007] Preferably, the feed port is located on a side away from the discharge port of the conveying cylinder.

[0008] Preferably, the support frame includes a base plate, a plurality of support rods fixed to the upper end of the base plate are fixedly connected to the conveying cylinder, and a plurality of universal wheels are fixed to the lower end of the base plate.

[0009] The beneficial effect is that: the utility model does not require a supporting component to be set at the discharge port of the conveying cylinder, and a universal joint is set in the conveying cylinder. The combination of the two can avoid blockage inside the conveying cylinder. When blockage occurs in the conveying cylinder, the spiral component can still rotate and discharge materials. The spiral component can rotate at different angles in the conveying cylinder, and the whole is in a free state, which is more flexible when used. It avoids blockage inside the conveying cylinder to a certain extent, improves the conveying efficiency, and avoids damage to the drive motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is a further explanation of the technical solution of the present invention with reference to the accompanying drawings:

[0015] like Figure 1 As shown, a new type of screw conveyor includes a support frame, which includes a base plate 1. Two support rods 11 are fixed to the upper end of the base plate 1. The two support rods 11 are of different heights and are fixedly connected to the conveying cylinder 2. Four universal wheels are fixed to the lower end of the base plate 1.

[0016] A feed port 21 is provided on one side of the conveying cylinder 2. The feed port 21 is located on the side away from the discharge port of the conveying cylinder 2. The feed port 21 is connected to the internal cavity of the conveying cylinder 2. A spiral component is placed inside the conveying cylinder 2. The spiral component includes a central shaft 5 and a spiral blade 51 fixed on the central shaft 5. A universal shaft 3 is fixed to one end below the central shaft 5. The universal shaft 3 is located in the conveying cylinder 2. A drive motor 4 is fixed to the outside of the lower end of the conveying cylinder 2. The rotating shaft of the drive motor 4 passes through the bottom wall of the conveying cylinder 2 and is fixedly connected to the universal shaft 3. One end of the spiral component extends out of the discharge port at the upper end of the conveying cylinder 2.

[0017] Working principle: When in use, the staff places the coal blocks into the conveying barrel 2 through the feed port 21, and then the staff starts the drive motor 4. The drive motor 4 drives the universal shaft 3 to rotate, and the universal shaft 3 drives the central shaft 5 to rotate. At this time, the spiral blades 51 drive the coal blocks to be transported. When the conveying barrel 2 is blocked, the universal shaft 3 will drive the central shaft 5 to deflect and rotate. The overall spiral component is in a relatively free state in the conveying barrel 2, which can effectively avoid blockage during coal transportation.

[0018] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
