Detailed Description

The present utility model will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1 and 2, the utility model provides a hydraulic hammer mill trolley connecting and fixing structure, which comprises a hammer mill trolley 1, wherein the hammer mill trolley 1 is used as a working carrier of a hydraulic hammer mill, the hydraulic hammer mill is fixed on the hammer mill trolley 1, a stepped hole 2 is arranged on a vehicle body bottom plate 11 of the hammer mill trolley 1, the large diameter end of the stepped hole 2 faces to the upper end surface of the vehicle body bottom plate 11, a connecting block 3 is arranged in the stepped hole 2, and the connecting block 3 is in a stepped shaft matched with the stepped hole 2. Through the structural arrangement of the stepped hole 2 and the stepped shaft, the position movement of the connecting piece in the working process can be reduced, and the loosening probability of the connecting block 3 is reduced. Preferably, the depth of the large diameter end of the stepped hole 2 is 1/3 of the depth of the vehicle body bottom plate 11. The strength of the connecting block 3 in the large-diameter end is ensured, and the anti-loosening effect is improved. The lower end of the connecting block 3 extends out of the stepped hole 2 towards the direction of the hydraulic striking machine, and a threaded hole 31 used for being connected with the hydraulic striking machine is arranged in the lower end of the connecting block 3 and used for fixing the hydraulic striking machine on the striking machine trolley 1.
