The invention discloses an electromagnetic drive type pressure roller. The electromagnetic drive type pressure roller comprises a roller body with the interior of a columnar hollow structure. An annular magnetic field is generated through the coil for guiding in directional current, the annular magnetic field forces iron balls located in the annular structure of the annular magnetic field to generate annular motion, and due to the fact that the annular flow generated by the iron balls is attached to the inner wall of an iron drum, the annular motion of the iron balls can generate pressure towards the outer wall of the iron drum; the pressure mainly comes from centrifugal force generated by high-speed running of iron balls, due to rotation of a roller and the high-strength centrifugal force, the roller can continuously generate downward pressure amplification, the amplification can increase the compaction work of the roller on a road surface or raw materials, due to the fact that the device utilizes the electromagnetic principle, the controllability of the rotating speed is high. Moreover, the iron balls rotate freely, so that the energy conversion rate is high, and the effect is relatively obvious.
本发明公开了一种电磁驱动式压力滚筒，包括内部为柱状中空结构的滚筒。本发明利用导入定向电流的线圈，产生环形磁场，该环形磁场迫使位于其环形结构内部的铁球产生环形运动，由于铁球产生的环形流动是附着在铁桶内壁，铁球的环形运动会产生向铁桶外壁的压力，该压力主要来源于铁球高速运转产生的离心力，由于滚筒自身旋转，再加上高强度的离心力，能够使得滚筒不断产生向下的压力增幅，该增幅能够增加滚筒对路面或者原材料的压实工作，由于该装置利用电磁原理，所以其旋转速度可控性强，并且，由于铁球为自由旋转运动，所以对于能量的转化率高，效果比较明显。
