ДИСК ТРИММЕРА

Полезная модель относится к механическим выбрасывателям, оснащенным диском, в частности к режущим устройствам с несколькими режущими ножами. Диск триммера выполнен в виде цельного основания, выполненного в виде четырех лепестковой крестовины. На концах каждого из лепестков выполнено соединительное отверстие. В последнем установлен, с возможностью углового перемещения, режущий элемент, выполненный в виде ножа. При вращении диска триммера в бензокосе (электрокосе), режущие ножи под действием центробежных сил принимают рабочее положение. При ударе режущего ножа диска триммера о препятствие, нож складывается в крестовину основания, не допуская поломки всего диска триммера, и исключает поломки вала или повреждения редуктора бензокосы (электрокосы). Диск триммера не требует заточки режущих ножей и не имеет изнашиваемых деталей. В случае поломки режущего ножа, заявленный диск триммер легко ремонтируется заменой ножа в полевых условиях.
