The rotational motion of the vibration motor 2 is transmitted to the above three groups of vibration shafts and their eccentric blocks through three controllable clutches D1, D2 and D3 in three paths. In the first route, the first transmission shaft 4 transmits the rotational motion to the second transmission shaft 6 through the transmission part 5, and then transmits the rotational motion to the first group of excitation shafts 8 and 10 and above through the controllable clutch D2 and the transmission part 7 The first group of eccentric blocks 9 and 11, the first group of excitation shafts 8 and 10 transmit the rotational motion to the second group of excitation shafts 18 and 15 and the second group of eccentric blocks 19 and 16.

working principle:

As shown in Figure 1, when the clutch D1 is on and the clutches D2 and D3 are off, the vibration motor 2 drives the eccentric block 21 to rotate through the clutch D1, so that the compaction wheel produces non-directional vibration compaction Effect, positive and negative two different rotation directions, resulting in two different excitation force amplitudes;

When the clutch D1 is in the disconnected state, the clutch D2 is in the connected state, and the clutch D3 is in the disconnected state, the excitation motor 2 drives two sets of eccentric blocks 9 and 11, 19 and 16 through the clutch D2 for the same rotation speed, same direction and eccentricity. Rotation with a phase difference of 180° from the vector, the excitation force generated by the two sets of eccentric blocks forms an exciting force couple moment in the rotation plane, so that the compaction wheel produces an oscillating compaction effect. If the positive rotation of each set of eccentric blocks produces Large-scale excitation force, reverse rotation produces a small-amplitude excitation force, and the rotation of the excitation motor in different directions causes the compaction wheel to produce two types of pure oscillation compaction with different amplitudes;

When the clutch D1 is in the on state, the clutch D2 is in the on state, and the clutch D3 is in the off state, the vibration motor 2 simultaneously drives three sets of eccentric blocks 21, 9 and 11, and 19 and 16 to rotate through the clutches D1 and D2, thereby Make the compaction wheel produce vibration and vibration mixed compaction, the rotation direction of eccentric block 21 is the same as the rotation direction of eccentric block 9 and 11 and 19 and 16, if the drive motor rotates in the forward direction, it will drive the three sets of eccentric blocks to move forward Rotation, the generated excitation force and the excitation force couple make the compaction wheel produce a large-value oscillation and a large-value vibration mixed compaction effect, if the drive motor rotates in the opposite direction, the excitation force and force couple generated by the reverse rotation of the three sets of eccentric blocks Make the compacting wheel produce small-amplitude oscillation and small-amplitude vibration mixed compaction;

When the clutch D1 is on, the clutch D2 is off, and the clutch D3 is on, the excitation motor 2 simultaneously drives three sets of eccentric blocks 21, 9 and 11, and 19 and 16 to rotate through the clutches D1 and D3, and the eccentric The direction of rotation of the block 21 is opposite to that of the other two sets of eccentric masses 9 and 11 , 19 and 16 . If the excitation motor rotates in the forward direction, it will drive the eccentric block 21 to rotate in the forward direction, and the eccentric blocks 9 and 11, 19 and 16 will rotate in the reverse direction. Large-scale vibration and small-amplitude vibration are combined for compaction; if the vibration motor 2 rotates in the reverse direction, the vibration motor 2 drives the eccentric block 21 to rotate in the reverse direction, and the eccentric blocks 9 and 11, 19 and 16 rotate in the forward direction. Rotation, the exciting force and force couple generated by the rotation of the three sets of eccentric blocks make the compacting wheel produce a mixed compaction effect of small-amplitude vibration and large-amplitude oscillation. Therefore, by controlling the on or off state of the clutches D1, D2, and D3, eight different vibration, oscillation, and mixed action functions of the compaction wheel can be realized.
