Abstract

The utility model belongs to an electric lawn cutting implement, which is characterized in that a cutter blade is driven by a direct current motor using a storage battery as energy resource to cut and level lawns by high speed rotation, and the included angle between the bottom plane of the cutter blade and the horizontal plane is 6 DEG to 9 DEG. The utility model has the advantages of power consumption saving, high efficiency, simple structure, convenient operation, low noise, light vibration, no environmental pollution and small possibility of failure.

Description

Electric lawn cutting implement

The utility model belongs to a kind of lawn and cuts smooth equipment, particularly a kind of electric lawn cutting planisher.

In order to beautify the environment, prevent air pollution, in avenue both sides, residential area, park, stadium, hospital, sanatorium, office, factory, school etc. locate mostly to be covered with the lawn.Because the lawn is in continuous growth, will become uneven through original smooth lawn after a while.Therefore, need repair, make the lawn, give beautiful enjoyment as the smooth softness of carpet through cutting planisher in special-purpose lawn commonly used.Existing lawn cutting planisher mainly is that power drives a blade high speed rotating and cuts smooth lawn with the gasoline engine, and the lawn cutting planisher that greening tools factory in Shanghai produces just belongs to this kind equipment.Be characterized in that power is big, efficient is high, but consumes energy is many, and the gas after the steam turbine oil burning is serious to atmospheric pollution.In addition, its noise is big, vibration is big, thereby also influences the effect on smooth lawn.Particularly the noise that sends of gasoline engine is not suitable for mutually with the environment utmost point that school, hospital, sanatorium etc. locate.This equipment operation, inconvenient maintenance, the rate of breakdown height cuts the cost height on smooth lawn.The also useful alternating current generator of lawn cutting planisher that uses at present is characterized in that noise is low, it is light, pollution-free to vibrate as power, and power consumption is many, the scope of application is little, operation is inconvenient and uneasy congruent shortcoming but still exist.

The purpose of this utility model is that the deficiencies in the prior art provide a kind of saving energy, noise is little, vibration is light in order to overcome, the blade cut angle is reasonable, cuts smooth lawn electric lawn cutting planisher effective, easy for operation.

The purpose of this utility model is finished as follows: is that blade high speed rotating on horizontal plane that the direct current generator of the energy drives one or two page of one cuts smooth lawn by one with a group storage battery, the angle of every page of blade bottom face and horizontal plane is 6 °～9 °, the end limit of two pages of blades also is processed into end limit cutting edge and is smoothly linked to each other with the side cutting edge, by regulating the blade height-regulating mechanism, the lawn can be cut the smooth required height that becomes.

The utility model compared with prior art has many advantages and good effect:

1, saves the energy.Owing to selected rational blade cut angle, and used efficient accumulator to be the energy, the used cost in the utility model finishing unit are lawn is that powered device saves 13/14 than with the gasoline engine, than with the alternating current generator being powered device saving 3/5.

2, free from environmental pollution, noise is little, vibration is light, the utilization scope is wide.

3, rate of breakdown is low, and is easy to maintenance.

4, compact conformation, volume are little, in light weight, easy for operation, and it is effective to cut smooth lawn, the efficient height.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the schematic diagram of blade inclination angle time cutting blade of grass less than 5 °;

Fig. 4 is the schematic diagram of blade inclination angle time cutting blade of grass greater than 10 °;

Fig. 5 is the schematic diagram of the utility model blade cuts blade of grass.

With reference to Fig. 1, Fig. 2, being equipped with one on the frame (2) is the direct current generator (5) of the energy with two efficient accumulatoies (7), the power transmission shaft (4) of direct current generator (5) perpendicular to horizontal plane and with the axis normal of the blade that is contained in its lower end (3).Blade (3) is two pages of one, and the axis of two pages of blades (3) is on same straight line, and the centre has a hole can be sleeved on the power transmission shaft (4), and the bottom face of two pages of blades (3) and the angle of horizontal plane are 6 °～9 °.Two of blade (3) end limits also are processed into cutting edge and are called end limit cutting edge (10) and smoothly link to each other with side cutting edge (11), and two cutting edge angle degree are identical.

The angle of choose reasonable blade (3) bottom face and horizontal plane is most important, when this angle during less than 5 °, as shown in Figure 3, the effect of the blade of high speed rotating (3) absorption blade of grass (14) obviously weakens, blade of grass (14) is to be cut disconnectedly under the state that becomes 35 °～40 ° of angles with horizontal plane, thereby cutting effect is poor, efficient is low.The bottom face of its blade of prior art (3) and the angle of horizontal plane are generally all greater than 10 °, as shown in Figure 4, at this moment, blade of grass (14) be adsorbed to become by the blade of high speed rotating (3) with horizontal plane angle be cut under 50 °～55 ° the state disconnected, cutting effect is relatively good like this, still because blade (3) thus the inclination angle is excessive to have caused that rotational resistance is excessive and causes the vibration of machine obviously to aggravate, energy resource consumption is increased, also influenced the smooth effect on lawn.Blade (3) bottom face and horizontal plane angle that the utility model is selected are 6 °～9 °, as shown in Figure 5, like this blade of grass (14) be when being adsorbed to become with the horizontal plane angle left and right sides at 45, be cut by the blade of high speed rotating (3) disconnected, at this moment, blade (3) rotational resistance is less, machine vibration is light, energy resource consumption obviously reduces, and smooth lawn is effective, efficient is high.

During use, earlier that accumulator (7) is charged, be pushed into then on the lawn that will repair, press the motor switch (13) that pushes away on the handle (9), blade (3) just under the drive of direct current generator (5) high speed rotating cut smooth lawn.The promotion machine advances, and the blade of grass under being cut (14) is just dished out the grass outlet (12) on keeping off grass cover (6).Because machine is constantly being pushed ahead, therefore, the end limit cutting edge (10) of blade (3) also can cut blade of grass (14), under the situation that does not increase blade (3) and machine dimensions, has improved the efficient of cutting smooth lawn like this.Adjust blade and heighten handle (8), four wheels (1) and the relative position of frame (2) are changed, thereby blade (3) is raise with frame (2) or reduce, so that cut the smooth lawn that goes out various desired heights.

Claims

1, a kind of by cutter drives mechanism, blade (3), wheel (1), blade height-regulating mechanism (8), retaining grass cover (6), push away handle (9) and wait the lawn of forming to cut planisher, it is characterized in that cutting smooth lawn with accumulator (7) for blade (3) high speed rotating on horizontal plane that the direct current generator of the energy (5) drives one or two page of one by one, blade (3) bottom face and horizontal plane angle are 6 °～9 °.

2, according to the described electric lawn cutting of claim 1 planisher, it is characterized in that the two ends of blade (3) are processed to hold limit cutting edge (10) smoothly to link to each other with side cutting edge (11).
