Problems solved by technology
The present invention can greatly extend the trouble-free working time of the resonance crusher, however, the crusher also has the following disadvantages: when the resonance crusher is in use, the connection between the beam of the crusher and the hammer head is simply through a large number of bolts Locking connection, the locking and fixing method is relatively single, the fixing effect is general, and due to the large number of fixing bolts used, it is necessary to repeat the steps of removing and installing bolts many times when replacing the hammer head, resulting in the replacement of the hammer head. work becomes time consuming

Embodiment
[0043] Example: Please refer to Figure 1 to Figure 9 :
[0044] The present invention proposes a cement pavement resonant stone crusher, comprising: a car body 6, a bearing seat 1 is fixedly installed on the loading platform in the middle of the car body 6; a resonant girder 2 is installed on the bearing seat 1 through a bearing; The rear end is provided with a vibration exciter 3; the front end of the resonant beam 2 is set with a sleeve 4; the bottom of the sleeve 4 is fixedly installed with a connector 5; the bottom of the connector 5 is fixed with a resonant hammer 501, through 3 Work to make the resonant girder 2 start to vibrate, so that the resonant girder 2 drives the resonant hammer head 501 to resonate, so that the resonant hammer head 501 crushes the road surface.
[0045] Furthermore, according to an embodiment of the present invention, as Figure 6 and Figure 7As shown, the internal front end of the resonance beam 2 is provided with a main groove 201, and the...

The invention provides a cement pavement resonance stone crusher, and relates to the technical field of road construction preparation, the cement pavement resonance stone crusher comprises a vehicle body, a middle loading platform of the vehicle body is fixedly provided with a bearing seat; a vibration exciter is arranged at the rear end of the resonance girder; the front end of the resonance girder is sleeved with a sleeving and fixing piece. A connecting body is fixedly mounted at the bottom of the sleeving and fixing piece; and a resonance hammer head is fixedly mounted at the bottom end of the connecting body. The sleeve fixing piece is provided with a plurality of different clamping fixing mechanisms, a plurality of clamping protection mechanisms are formed through the multiple clamping fixing mechanisms, the firmness degree between the sleeve fixing piece and the resonance girder is enhanced, and the stability between the resonance hammer head and the resonance girder is extremely high; the problems that an existing connecting mode of a girder and a hammer head of the stone crusher is simply locked and connected through a large number of bolts, the locking and fixing mode is single, and due to the fact that the number of used fixing bolts is large, the steps of dismounting and mounting the bolts need to be repeated for multiple times when the hammer head is replaced are solved.
Description
technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a cement pavement resonance stone crusher. Background technique [0002] The road resonance crusher is used for crushing old cement pavement. The principle of the resonance crusher is that the exciter generates eccentric force. After amplitude modulation and frequency modulation through the resonant beam, the beam resonates and drives the crushing hammer to generate high-frequency and low-amplitude vibration. , so that the vibration frequency of the hammer reaches or approaches the natural frequency of the concrete panel. Resonance crushers are divided into two categories, namely offset beam crushers and center beam crushers. [0003] For example, the patent application number CN202011425072.2 discloses a resonant crusher. The exciting beam is connected to the vehicle body through a supporting shaft, a flexible supporting bushing is provided between the suppor...
