One end of each support frame is provided with a blanking inclined plane, and the other end of each support frame is connected with an inclined feeding trough. A number of first "V"-shaped grooves are formed at the upper end of each support frame, which are distributed at intervals from the blanking inclined plane to the feeding trough direction. A conveying frame is arranged between the two support frames. A number of second "V"-shaped grooves corresponding to the first "V"-shaped grooves one by one are formed at the upper end of the conveying frame. Driving rods are respectively hinged at both ends of the conveying frame. The two driving rods are arranged in parallel. The other ends of the two driving rods are hinged to the frame, and the middle parts of the two driving rods are connected by a hinged connecting rod. One of the rotating rods is driven by a driving mechanism to rotate on the frame.

[0006] Preferably, the driving mechanism includes a first motor. A first synchronous pulley is arranged on the output shaft of the first motor. The rotating rod is rotatably installed on the frame through a rotating shaft. The rotating shaft is rotatably installed on the frame and is fixedly connected with the rotating rod. A second synchronous pulley is fixedly installed on the rotating shaft. The first synchronous pulley and the second synchronous pulley are connected by a belt drive.

[0007] Preferably, the distance between the two support frames can be adjusted by a distance adjusting mechanism.

[0008] Preferably, the distance adjusting mechanism includes two moving blocks. The two moving blocks are located between the two support frames and at both ends of the support frames. A connecting rod is respectively hinged on both sides of each moving block. The other ends of the connecting rods on both sides of the moving block are respectively hinged to the two support frames. A double-threaded screw rod is arranged through the two moving blocks. The double-threaded screw rod is rotatably installed on the frame and is driven to rotate by a second motor.

[0009] In a preferred technical solution, the lower ends of the two support frames are installed on the slide rail, the slide rail is fixedly connected to the machine frame, and the length direction of the slide rail is parallel to the connection direction of the two support frames.

[0016] An intermittent conveying mechanism for circular steel pipes, comprising a frame. Two support frames 1 are arranged at intervals on the frame. One end of the support frame 1 is provided with a feeding inclined plane 3, and the other end of the support frame 1 is connected with an inclined feeding trough 4. A number of first "V"-shaped grooves 2 are arranged at intervals in the upper end of the support frame 1 in the direction from the feeding inclined plane 3 to the feeding trough 4. A conveying frame 5 is arranged between the two support frames 1. A number of second "V"-shaped grooves 6 corresponding to the first "V"-shaped grooves 2 one by one are arranged at the upper end of the conveying frame 5. One end of the conveying frame 5 is respectively hinged with a driving rod 7. The two driving rods 7 are arranged in parallel. The other ends of the two driving rods 7 are hinged with the frame, and the middle parts of the two driving rods 7 are connected by a hinged connecting rod. The two driving rods 7, the conveying frame 5 and the connecting rod are arranged in a parallelogram shape. One of the rotating rods is driven by a driving mechanism to rotate on the frame.

[0017] Place the circular steel pipes in the feeding trough 4. The circular steel pipes slide down along the feeding trough 4 and fall into the first "V"-shaped grooves 2 on the support frame 1. The conveying frame 5 rotates vertically around the frame through the driving rod 7. When the conveying frame 5 rotates upwards, the second "V"-shaped grooves 6 on the conveying frame 5 lift up the circular steel pipes on the support frame 1, and move the circular steel pipes forward as the conveying frame 5 rotates forward. When the conveying frame 5 rotates downwards, the circular steel pipes are placed in the previous first "V"-shaped grooves 2 on the support frame 1, so that the circular steel pipes are moved forward by one grid. Through the continuous rotation of the support frame 1, a number of circular steel pipes are separated one by one and conveyed downwards until the circular steel pipes are placed on the feeding inclined plane 3. Through the utility model, a number of circular steel pipes can be separated one by one and conveyed forward intermittently.

[0018] Further, the driving mechanism comprises a first motor 9. A first synchronous pulley is arranged on the output shaft of the first motor 9. The rotating rod is installed on the frame through a rotating shaft and rotates. The rotating shaft is rotatably installed on the frame. The rotating shaft is fixedly connected with the rotating rod. A second synchronous pulley is fixedly installed on the rotating shaft. The first synchronous pulley and the second synchronous pulley are connected by a belt 8.

[0019] The first motor 9 drives the first synchronous pulley to rotate, thereby driving the second synchronous pulley to rotate through the belt 8, and then driving the rotating shaft to rotate.

[0020] Further, the distance between the two support frames 1 can be adjusted by a distance adjusting mechanism.

[0021] Adjusting the distance between the two support frames 1 is convenient for conveying circular steel pipes of different lengths.

[0022] Further, the distance adjusting mechanism includes two moving blocks 11. The two moving blocks 11 are located between the two support frames 1 and at both ends of the support frame 1. One connecting rod 12 is hinged on each side of the moving block 11. The other ends of the connecting rods 12 on both sides of the moving block 11 are respectively hinged to the two support frames 1. A double-threaded screw rod 13 is arranged between the two moving blocks 11. The double-threaded screw rod 13 is rotatably installed on the frame and driven to rotate by a second motor.

[0023] The second motor drives the double-threaded screw rod 13 to rotate, so that the two moving blocks 11 move on the double-threaded screw rod 13, driving the connecting rods 12 to rotate, thereby adjusting the two support frames 1 to move towards or away from each other.

[0024] Further, the lower ends of the two support frames 1 are installed on the slide rail 10. The slide rail 10 is fixedly connected to the frame. The length direction of the slide rail 10 is parallel to the connection direction of the two support frames 1.
