The impact roller consists of a tractor and a compaction device, which are connected through a buffer frame connecting component.

The mbd. type impact roller tractor tractor is divided into front and rear frames, and the middle is connected by a steering winch as the rotation center of the hydraulic cylinder steering mechanism. The front frame houses components such as the engine, hydraulic transmission, front axle, and cab.

The compaction device is mainly composed of compaction wheel assembly, frame, connecting rod frame, traveling wheel, connector, anti-rotation device and hydraulic cylinder. The buffer mechanism composed of connecting rod, limit rubber block and buffer hydraulic cylinder is to prevent and reduce the impact of the impact wheel on the frame. The impact compaction wheel is a working part, which is two non-cylindrical rollers composed of several curves. They are distributed on both sides of the frame and are connected by a wheel shaft in the middle. The rollers are welded with thick steel plates. The lifting mechanism and traveling mechanism composed of lifting cylinder, anti-rotation device, connecting rod frame, traveling wheels, etc. are mainly used for short-distance transfer and replacement of construction sites. When the lifting hydraulic cylinder is extended, the two impact wheels leave the ground. At this time, the entire mass is borne by the four traveling wheels, and the site transfer is realized under the drag of the tractor. The purpose of the anti-rotation device is to prevent the impact wheel from rotating freely during short transfers on the construction site.

The compaction device and the tractor are connected through a connecting device. The connecting device consists of a traction wrench, a cross joint, a pin, a traction shaft, a flange and a buffer rubber sleeve, which can buffer The impact wheel impacts the tractor and changes its stress state during the towing process, ensuring three degrees of rotational freedom between the tractor and the compaction device. When the tractor drags the compactor wheel to roll forward, the height of the compactor wheel's center of gravity from the ground alternately changes up and down, and the potential energy and kinetic energy generated are concentrated and rolled forward and downward, forming a huge shock wave that continuously passes through the polygonal arc wheel. Impact the ground evenly to make the soil evenly dense.
