Description

Technical Field

[0001] The utility model belongs to the technical field of pipe pile production, and more specifically, particularly relates to a material conveying device for pipe pile production. Background Art

[0002] When producing pipe piles, it is necessary to first place the steel cage in the steel mold, then transport the cement concrete into the steel mold through the feeding device, then put the two halves of the steel mold together, and then place the steel mold on the rotating shaft. The centrifugal force generated by the rotation of the steel mold makes the cement concrete in the mold adhere to the inner wall of the mold and combine with the steel cage to form the pipe pile.

[0003] For example, CN220561822U discloses a material conveying device for concrete pipe pile production, comprising a base and an auxiliary unloading structure, wherein support frames are fixedly connected to the left and right sides of the top of the base, a driving motor is fixedly connected to the top of the supporting frame, the output end of the driving motor is directed toward the side of the middle of the base, a front stirring shaft is fixedly connected to the output end of the driving motor, and a conveying box is rotatably connected to the left and right sides of the stirring shaft, and the auxiliary unloading structure is installed on the top of the base and the bottom of the conveying box; the auxiliary unloading structure comprises a servo motor, and the output end of the servo motor is directed toward the upper part; the material conveying device for concrete pipe pile production has an auxiliary unloading structure installed on the upper part of the base of the conveying device, and the auxiliary unloading structure can assist the discharge pipe at the bottom of the conveying box to speed up the discharge after the conveying device conveys the material to the destination, thereby enhancing the practicality of the conveying device and other advantages.

[0004] Based on the above, when cement concrete is added to the steel mold, it is easy for the cement concrete to collide with the steel cage, causing some stones to burst everywhere. In order to avoid material waste, baffles need to be installed on both sides of the discharge port. The existing baffles are plate-shaped. When the discharge port moves down, the baffles will block both sides of the width direction of the steel cage, but a small amount of stones will still burst out on both sides of the length direction of the steel cage, resulting in poor protection of the baffle, affecting the use effect of the conveying device.
