Specific implementation mode
As shown in Fig. 1~Fig. 6, a kind of simple rope pulley device, by rope sheave ontology 1（Including upper end 2, embedded nut 3, prevent
Protect boss 6, cylinder 7, central through hole 9, rope stretching through-hole 8, rope stretching through-hole small end 8-1, rope stretching through-hole big end 8-2, the first center
Line 10, the second center line 11）, rope-locking block 4（Including wire rope handling through-hole 4-1）It is formed with tightrope 5.
Central through hole 9 is located on 1 central axis of rope sheave ontology, and it is logical that 1 upper end embedded nut 3 of rope sheave ontology is inlaid in center
At hole 9, embedded nut 3 is connected with the grass-mowing machine transmission shaft end of thread.The lower end of rope sheave ontology 1, which is equipped with, prevents tightrope 5 from contacting
The protection boss 6 on ground.
Two wire rope handling through-hole 4-1 are arranged in " eight " font in rope-locking block 4, and rope-locking block 4 is inlaid in the cylinder of rope sheave ontology 1
On 7 walls, two wire rope handling through-hole 4-1 center line intersection points tend to 7 center of cylinder, and two rope stretching through-holes 8 are arranged symmetrically in the first center line
10 both ends；Tightrope both ends are each passed through after two wire rope handling through-hole 4-1 after central through hole 9, two rope stretching through-holes 8 described in stretching respectively
Outside cylinder 7；The rope stretching through-hole 8 is flat " horn mouth " type, and it is open from inside to outside by cylinder 7 to be open, i.e. tightrope is from rope stretching
Through-hole small end 8-1 enters, and is stretched out from rope stretching through-hole big end 8-2, and all channels that tightrope passes through are round and smooth structure.
Specific work process：Engine is started, power passes to rope pulley device and tightrope rotation is driven to carry out operation of beating the grass；By
It is arranged in " eight " font in two wire rope handling through-holes in rope-locking block, tightrope is securely locked in rope-locking block, since rope stretching through-hole is flat " loudspeaker
Mouth " type, tightrope have certain activity space, are unlikely to be broken off, meanwhile, all channels that tightrope passes through are round and smooth knot
Structure ensure that tightrope service life.
Advantageous effect is：Compared with traditional rope sheave, the rope sheave is simple in structure, changes rope conveniently, price is low, due in rope-locking block
The two ingenious arrangements of wire rope handling through-hole, tightrope is securely locked in rope-locking block, simultaneously because the wearability of rope-locking block material, ensure that rope
The use reliability of wheel construction is round and smooth knot since rope stretching through-hole is all channels that flat " horn mouth " type and tightrope pass through
Structure ensure that tightrope service life.
