Abstract
The utility model discloses a kind of blade mechanisms for air-cushion type grass mower, comprise: cutterhead, blade, side's strength screw bolt and nut, described blade is located on cutterhead by square strength bolt, the top of the described nut side of being threaded onto strength bolt, a kind of blade mechanisms for air-cushion type grass mower described in the utility model, by blade and cutterhead being separated the method for assembling, even if realization blade is stamped hard protrusion and is also unlikely to break case, thus operator is played a very good protection, also extend grass mower service life simultaneously, and then better meet consumer demand, described cutterhead adopts the cutterhead of the compacting shape made through compression process sheet metal, and its light weight, hardness are strong, the use of handled easily person, described blade adopts the blade of specific alloy steel making, can ensure that it has enough toughness in use procedure, and then further increase the quality of blade mechanisms, safety is improved greatly.
Description
Technical field
The utility model relates to a kind of blade mechanisms, specifically a kind of blade mechanisms for air-cushion type grass mower.
Background technology
Along with socioeconomic fast development, people are not only more and more higher to the requirement of quality of life, and the requirement for environmental quality is also more and more higher, and each city is all improving constantly the area of greening, and every a slice greenery patches all can irregularly be pruned it.
On market, the blade mechanisms of existing grass mower is as figure, it is mainly by tool rest, adjusting ring, blade, axle head cover and coupling band are screwed in together rigidly by fastening bolt, its case is mostly engineering plastics material, the screw-down torque of bolt is very large, the blade of High Rotation Speed is when running into protruding barrier, because of the blade cuts of High Rotation Speed rubble out, the casing of engineering plastics material may be punched, and then personal injury is caused to operator, and case is once damage, air-cushion type grass mower can be directly caused again to work, thus the large blade mechanisms of existing grass mower can not meet the demand of client.
Utility model content
Utility model object: the purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of blade mechanisms for air-cushion type grass mower.
Technical scheme: in order to realize above object, a kind of blade mechanisms for air-cushion type grass mower described in the utility model, comprise: cutterhead, blade, square strength screw bolt and nut, described blade is located on cutterhead by square strength bolt, the top of the described nut side of being threaded onto strength bolt, described cutterhead is provided with square hole.A kind of blade mechanisms for air-cushion type grass mower described in the utility model; by the method that blade and cutterhead separately assemble; effectively prevent from stamping hard protrusion because of blade to break case and cause unnecessary injury to operator; operator is played a very good protection; also extend grass mower service life simultaneously, and then better meet consumer demand.
Cutterhead described in the utility model adopts the cutterhead of the compacting shape made through compression process sheet metal, effectively overcomes aluminium panels and not easily purchases and the shortcoming that hardboard is low, cost is high, and its light weight, hardness are strong, the use of more convenient operator.
Blade described in the utility model adopts the blade of specific alloy steel making, and its knife number be located on cutterhead is more than or equal to two panels, and the blade of specific alloy steel making can ensure that it has enough toughness in use procedure.
Square hole size on the square strength size of side's strength bolt described in the utility model and cutterhead matches, and can be good at blade to be installed on cutterhead, improves its stability.
Nut described in the utility model adopts the nylon locking nut with flange face, and can better be fixed in cutterhead by blade, the stability that blade is connected with cutterhead and safety be improved.
Beneficial effect: the blade mechanisms for air-cushion type grass mower described in the utility model, has the following advantages:
1, a kind of blade mechanisms for air-cushion type grass mower described in the utility model; by blade and cutterhead being separated the method for assembling; even if realization blade is stamped hard protrusion and is also unlikely to break case; thus operator is played a very good protection; also extend grass mower service life simultaneously, and then better meet consumer demand.
2, the cutterhead described in the utility model adopts the cutterhead of the compacting shape made through compression process sheet metal, and its light weight, hardness are strong, the use of handled easily person; Described blade adopts the blade of specific alloy steel making, can ensure that it has enough toughness in use procedure, and then further increase the quality of blade mechanisms, safety is improved greatly.
