The differential transmission gear box 3 has a first transmission shaft 15 and a second transmission shaft 16 in a box 17, and the first transmission shaft 15 and the second transmission shaft 16 are respectively supported on bearings at corresponding positions of the box 17. An idle gear is fixedly connected to each of the first transmission shaft 15 and the second transmission shaft 16, the left central gear 11 is fixedly connected to the input shaft 10, one part of the first idle gear 13 on the first transmission shaft 15 is meshed with the left central gear 11, the other part of the first idle gear 13 on the first transmission shaft 15 is meshed with one part of the second idle gear 14 on the second transmission shaft 16, the other part of the second idle gear 14 is meshed with the right central gear 12, the second idle gear 14 and the left central gear 11 are axially arranged in a staggered mode without interference, the number of teeth of each gear is set to meet the rotating speed of the second excitation transmission gear 42 and the rotating speed of the third excitation transmission gear 43, the right central gear 12 and the output gear 24 are fixedly connected into a whole and supported on the input shaft 10 and the box body 17 through bearings. The left end of the input shaft 10 is supported on the left end of the box body 17 of the differential transmission gear box 3 through a bearing, the right end of the input shaft 10 is supported on the cylinder 20 through a bearing, and the left end of the differential transmission gear box 3 is directly supported on a central bearing at the left end of the cylinder 20 or supported on a central bearing at the left end of the cylinder 20 through the input shaft 10. The differential drive gearbox 3 is connected to a motor 9 fixed to a frame 21 via an adjusting shaft 8.
The working principle is as follows: suppose the rotation axis O of the first and second excitation shafts 1, 2 1 -O 1 、O 2 -O 2 The plane of (a) is referred to as the P-P plane and the plane passing through the center line O-O of the vibratory wheel 22 and perpendicular to the P-P plane is referred to as the Q-Q plane. When the first group of combined eccentric blocks 18 produce an exciting force vector
The excitation force vector generated by the eccentric mass 19 in combination with the second set
(wherein
) When the eccentric blocks are symmetrically distributed relative to a Q-Q plane, the resultant force direction of the excitation forces generated by the two groups of eccentric blocks is always vertical to the plane P-P (as shown in figures 2 and 4), and the excitation resultant force direction is vertical to the compacted ground, namely the vibration wheel 22 performs vertical directional vibration; when the initial phase angle of the eccentricity vector of the first group of combined eccentric blocks 18 is unchanged and the initial phase angle of the eccentricity vector of the second group of combined eccentric blocks 19 is changed by an angle beta, the resultant force direction of the exciting forces generated by the two groups of eccentric blocks forms an included angle beta/2 with a Q-Q plane, the vibrating wheel 22 performs hybrid vibration, and the magnitudes of the vertical vibration component and the horizontal vibration component depend on the angle beta/2. When β/2=90 °, the vibrating wheel 22 vibrates in an oscillating manner, and the vertical vibration component thereof is zero.
The transmission process is that an excitation vibration force source 7 drives an excitation transmission shaft 5 to rotate through a coupling 6, a first excitation transmission gear 41 on the excitation transmission shaft 5 drives a second excitation transmission gear 42 on an excitation shaft 1 to rotate, so as to drive a first group of combined eccentric blocks 18 on the excitation shaft 1 to rotate, meanwhile, the excitation transmission shaft 5 drives an input shaft 10 to rotate through a coupling 23, a left central gear 11 fixed on the input shaft 10 sequentially drives a first intermediate wheel 13, a second intermediate wheel 14 and a right central gear 12 to rotate, the right central gear 12 drives a coaxially fixed output gear 24 to rotate, and the output gear 24 drives a third excitation transmission gear 43 fixed on the excitation shaft 2 to rotate, so as to drive a second group of combined eccentric blocks 19 on the excitation shaft 2 to rotate. Due to the transition of the differential gear, the first and second sets of combined eccentric masses 18, 19 rotate in opposite directions and at equal rotational speeds.
When the vibration mode is adjusted, the motor 9 or the swing hydraulic cylinder drives the differential transmission gearbox 3 to integrally rotate through the adjusting shaft 8, because the left central gear 11 of the differential transmission gearbox 3 is fixedly connected with the input shaft 10, and if the input shaft 10, the coupling 23 and the excitation transmission shaft 5 are relatively fixed, the first intermediate wheel 13 (namely the planet wheel) performs planetary rotation around the left central gear 11, and sequentially drives the second intermediate wheel 14, the right central gear 12, the output gear 24, the third excitation transmission gear 43, the excitation shaft 2 and the second group combined eccentric block 19 to rotate, so that the second group combined eccentric block 19 on the excitation shaft 2 obtains additional rotation. According to the transmission ratio principle of epicyclic gear train, if the box 17 (note: equivalent to tie bar) of the differential transmission gear box 3 is rotated by beta/2 angle, the additional rotation angle of the second group of combined eccentric blocks 19 is beta angle, even if the initial phase angle of the eccentricity vector of the second group of combined eccentric blocks 19 is changed by beta angle (as shown in FIG. 4), and if the first group of combined eccentric blocks 18 is not moved at this time, the resultant force of exciting forces generated by the two eccentric blocks is assumed
The direction changes by an angle beta/2. Therefore, the motor 9 or the swing hydraulic cylinder can drive the second group of combined eccentric blocks 19 to additionally rotate through the adjusting shaft 8, the differential transmission gear box 3, the output gear 24, the third excitation transmission gear 43 and the excitation shaft 2 until the initial phase angle of the eccentricity vector of the second group of combined eccentric blocks 19 rotates by a preset angle, a preset vibration mode is obtained, and excitation is carried out in the vibration mode.The adjustment of the vibration mode can be achieved by continuously adjusting the rotation angle of the differential drive gearbox 3 at any condition during operation, i.e. in the excited state or in the non-excited state, so that the initial phase angle of the eccentricity vectors of the second set of combined eccentric masses 19 is rotated through a predetermined angle. The adjustment variation range of the vertical vibration component and the oscillation component of each vibration mode is 0-A (note: A is the maximum vertical amplitude), and the specific size depends on the included angle between the direction of the excitation resultant force and the Q-Q plane.
