In order more to be expressly understood above-mentioned purpose of the present invention, feature and advantage, the present invention is further described in detail below in conjunction with the accompanying drawing and the specific embodiment.Need to prove that under the situation of not conflicting, the application's embodiment and the characteristic among the embodiment can make up each other.
A lot of details have been set forth in the following description so that make much of the present invention; But; The present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention does not receive the restriction of following disclosed specific embodiment.
Fig. 1 is the perspective view according to the adjustable vibrating device of the amplitude of the embodiment of the invention; Fig. 2 is the fractionation sketch map according to the amplitude modulation apparatus of the embodiment of the invention; Fig. 3 is the view of amplitude modulation apparatus when clockwise rotating according to the embodiment of the invention; Fig. 4 is the view of amplitude modulation apparatus when rotating counterclockwise among Fig. 3.
Extremely shown in Figure 4 like Fig. 1, the vibrating device that amplitude provided by the invention is adjustable, comprising eccentric shaft 1 and be installed in also can be with the amplitude modulation apparatus 2 of eccentric shaft 1 rotation on the eccentric shaft 1; Amplitude modulation apparatus 2 comprises housing 21, and be installed in the housing 21, the block 22 along housing 21 circumferential arrangement, movable eccentric block 23 and have the elastic body 24 of pretightning force; Block 22 is fixed in the housing 21, and movable eccentric block 23 is installed in the housing 21 movably, and elastic body 24 is installed between block 22 and the movable eccentric block 23; The eccentric part of movable eccentric block 23 is positioned at eccentric phase the same side of eccentric shaft 1.
Through the above embodiments of the present invention, because of the off-centre of the eccentric part of movable eccentric block 23 and eccentric shaft 1 in the same side, guarantee that eccentric shaft 1 turns clockwise or the eccentric throw when not changeing is maximum; It is maximum that amplitude also reaches, and along with rotating counterclockwise of eccentric shaft 1, movable eccentric block 23 begins to rotate; Amplitude slowly diminishes, and has realized the multistage adjusting of vibrating device amplitude, and it is simple in structure; Cost is low; And need not increase extra amplitude adjustment power, and vibrating device of the present invention is applied on the road roller, can adapt to various roadbed situation.
The operating principle of the vibrating device that this amplitude is adjustable, like Fig. 3 and shown in Figure 4:
Like Fig. 3, when the clockwise low speed rotation of eccentric shaft 1, movable eccentric block 23 is close to block 22, and this moment, the amplitude of amplitude modulation apparatus 2 was maximum, thereby the amplitude of whole vibrating device is maximum.
