FIG. 1 is a schematic structural diagram of a cutter head structure of a mower according to an embodiment of the utility model;
FIG. 2 is an exploded view of the cutter head structure of the mower in accordance with the embodiment of the present invention;
fig. 3 is a side view of the cutter head structure of the mower according to the embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-3, the present invention provides a cutter head structure of a lawn mower, which includes: the cutter head 10, the cutter 11, the first protection plate 21, the second protection plate 22, the connecting seat 31 and the supporting seat 32.
The plurality of cutters 11 are arranged at intervals along the circumferential direction of the cutter disc 10, the cutters 11 are fixedly connected to the cutter disc 10 through screws, a first connecting hole 41 is formed in the cutter disc 10, and the connecting seat 31 is fixed to the bottom of the cutter disc 10 through the screws connected to the first connecting hole 41.
The second guard plate 22 is located between blade disc 10 and the first guard plate 21, and the external diameter of second guard plate 22 is less than the external diameter of first guard plate 21, and the external diameter of blade disc 10 is the same with the external diameter of first guard plate 21, realizes the protection to blade disc 10 bottom jointly through first guard plate 21 and the second guard plate 22 that set up in blade disc 10 below, prevents effectively that rock sand grain from causing the damage to the bottom surface of blade disc 10 or cutter 11 junction.
Set up fixed orifices 23 on the first guard plate 21, set up second connecting hole 42 on connecting seat 31 and the supporting seat 32 respectively, supporting seat 32 is located between second guard plate 22 and the first guard plate 21, and the screw is worn to establish through fixed orifices 23 and is worn to locate respectively and link to each other at the second connecting hole 42 of supporting seat 32 with connecting seat 31, realizes the centre gripping to second guard plate 22 by supporting seat 32 and connecting seat 31.
