Abstract
The invention relates to a grass mowing plate for mowing lawns, bushes and the like and aims to overcome the defects that existing grass mowing plates are low in lawn mowing efficiency and difficult to mow plants such as the bushes. The grass mowing plate comprises an upper plate, a lower plate and blades, wherein the upper plate and the lower plate are mounted together, and a cavity is formed between the upper plate and the lower plate, a plurality of blade openings are formed in the lateral side of the lower plate, an edge is disposed on side of each blade, the blades are movably mounted in the cavity formed by the upper plate and the lower plate and correspond to the blade openings in the lower plate, and power drives the blades to extend out of the blade openings and rotate fast to perform mowing. When grass mowing plate is not used, the blades retract into the grass mowing plate, and cut caused by accidental touch is avoided. Compared with the existing grass mowing plates, the grass mowing plate is efficient in mowing of the lawns, the bushes and the like, and safe and convenient to operate.
Description
Technical field
The present invention relates to gardens fixture fields, particularly a kind of dish of beating the grass pruned for lawn, shrub etc.
Background technology
Dish of beating the grass is the key fitment of the gardens pruning instruments such as mower, is usually used in turf-mown.Existing dish of beating the grass is that the shearing force utilizing the rope of high-speed rotation or chain to produce is pruned lawn, and pruning efficiency is not high; Pruning for the small-sized woody plant of brambles, shrub etc. is very required great effort, and the loss in pruning process of rope or chain is very large.
Summary of the invention
The object of the invention is not high for the existing efficiency that cuts the grass on a lawn of beating the grass existing for dish, not easily to the weak point that shrub etc. plant is pruned, provide a kind of and synchronously all effectively dish of beating the grass pruned to lawn, shrub etc.
The present invention completes in the following way: one is beaten the grass dish, and this dish of beating the grass comprises dish, lower wall and blade, and upper dish and lower wall are fitted together, and middlely forms cavity; The side of lower wall is provided with several knife-edges; Blade side is provided with blade, blade be contained in that dish and lower wall formed movably cavity in, corresponding with the knife-edge on lower wall, drive bottom knife to stretch out and fast rotational from knife-edge at power, carry out pruning work; When dish of beating the grass does not work, blade is retracted in beats the grass in dish, avoids surprisingly touching the incised wound caused.
Beat the grass in dish described, the top of described blade is provided with locating hole, and the medial surface of upper dish is provided with the locating dowel coordinated with locating hole, and locating hole is sleeved in locating dowel, is provided with spring between locating hole and locating dowel, and blade can shrink under the restoring force effect of spring; Be provided with stopper slot below locating hole on blade, the medial surface of lower wall is provided with the limited post coordinated with stopper slot, and limited post is stuck in stopper slot.
Beat the grass in dish described, the blade on described blade is tooth-shape structure, and several profile of tooth blades become arc line shaped to be arranged on the side of blade.
Beat the grass in dish described, the outer surface of described upper dish is provided with guide vane one, and the outer surface of lower wall is provided with guide vane two, after upper dish and lower wall cover, guide vane one and guide vane two towards identical.
Beat the grass in dish described, described lower wall is provided with bottom, and bottom covers in the center of lower wall for dust-proof.
Beat the grass in dish described, in described blade, be provided with mold insert.
Beat the grass in dish described, described blade has two to six.
Beat the grass in dish described, described blade is provided with two to six blades.
Beat the grass in dish described, described upper dish and lower wall are circle.
When adopting the present invention to carry out gardens pruning work, blade screws out from knife-edge, fast rotary under power drives then do not change any bit tool and just can carry out synchronously pruning to lawn, brambles and shrub; The surface of upper dish and lower wall is provided with wind guide strip, upper dish is when beating the grass dish work, High Rotation Speed produces whirlwind, the buoyancy that this rotation produces makes the things such as the branch of pruning grass float on height certain above dish of beating the grass, and the branch floated grass waits thing to spread towards periphery by the angle of upper dish wind guide strip to a certain extent, be convenient to prune motion flexibly; The buoyancy that lower disc spins the produces dish that makes to beat the grass floats on the top certain altitudes such as lawn and saves lawn sprouting from damage, directly can not get to soil and damage lawn root system; When dish of beating the grass does not work, blade is collapsible beating the grass in dish, effectively avoids surprisingly touching the incised wound caused; It is convenient to change after the blade abrasion of beating the grass in dish.
Use the present invention carry out lawn, brambles and shrub pruning, there is good dynamic balancing, can greatly reduce windage and centrifugal action, easy to operate, prune efficiency high.
The present invention, compared with existing dish of beating the grass, adopts built-in metal blade, and pruning efficiency is high; Encounter the hard object such as stone, wall foot or curb during work, avoid powerful recoil to ensure the feature of easy-to-operate because blade has the pruned length of retractility.
