Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a walking electric mower for repairing landscaping lawn comprises a frame 1, a driving mechanism 2 is fixedly mounted at the top end of the frame 1, a walking wheel set 3 is arranged outside the frame 1, a set of mounting plates 4 are respectively arranged at two sides of the bottom end of the frame 1, a fixing support 6 is fixedly mounted at the bottom end of the mounting plates 4 through an elastic sleeve 5, an output shaft of the driving mechanism 2 is in transmission connection with a transmission shaft i 7 through a coupler, the other end of the transmission shaft i 7 is in transmission connection with a transmission shaft ii 9 through a universal coupling joint 8, the bottom end of the transmission shaft ii 9 penetrates through and extends to the bottom of a fixing support 6 and is fixedly mounted with a transmission disc 10, three sets of cutting lines 11 are pinned at the outer surface of the transmission disc 10, a clamping sleeve 12 is pinned at the other end of the cutting lines 11, a support ring i 13 is fixedly mounted at the bottom, the cutting ferrule 12 passes through the clearance between support ring I13 and support ring II 14 and with support ring I13 fixed connection, and the surface of support ring I13 is connected through friction drive between friction ring 15 and the driven frizing 16, and driven frizing 16 is located the middle part of two sets of fixed bolster 6 inner chambers.

The elastic sleeve 5 is arranged, so that a certain amount of expansion difference can be kept between the fixed support 6 and the components on the fixed support and the rack 1, the influence of the impact on the cutting line 11 can be effectively relieved when the rack 1 is inclined due to depression of a lawn, the height position of the fixed support 6 can be adjusted by adjusting the expansion amount of the elastic sleeve 5, the cutting amount of the electric cutting machine on the lawn can be controlled, and meanwhile, the elastic sleeve 5 is matched with the universal coupling joint 8, so that good transmission performance can be kept even if the fixed support 6 and the output shaft of the driving mechanism 2 are inclined.

The arrangement of the cutting line 11 can utilize the impact force generated during high-speed rotation to cut and trim the lawn, and meanwhile, the arrangement of the support ring I13 and the friction ring 15 is matched, so that the driven scraping disc 16 can be driven to rotate along with the reduction of speed, and hard sundries such as small stones on the walking path of the electric cutting machine can be moved to the positions on the two sides of the electric cutting machine without violent impact collision between the electric cutting machine and the cutting line 11 rotating at high speed.

In this technical scheme, the both sides of 6 bottoms of fixed bolster are established to the arc structure, and highly be less than driven frizing 16 thickness between the upper and lower both sides of its inner chamber.

Wherein, to the setting of fixed bolster 6, when frame 1 took place to incline because of the pothole in lawn, can be timely support the installation part on and drive plate 10, make it can not take place to contact with the soil on the lawn because of the slope of frame 1, and then can form effective protection to the root on lawn, can not cause the impaired phenomenon of necrosis of turf root when utilizing this electric mower to cut the lawn, stability and reliability are higher.

In this technical scheme, the surface of driven frizing 16 is equipped with the chip removal spout the same with the cutting line 11 cutting direction, and what driven frizing 16 adopted is that elastic rubber material makes forms.

When the driven scraping disc 16 rotates along with the transmission disc 10 and the cutting line 11 under the action of the support ring II 14, hard impurities such as small stones on the lawn can be effectively pushed to the cutting edge of the cutting line 11, so that the hard impurities do not collide with the cutting line 11 rotating at a high speed, and the service life of the cutting line 11 is effectively prolonged.

In this technical scheme, the bottom of fixed bolster 6 remains the top position of walking the wheelset 3 bottom all the time.

Wherein, to the setting of position relation between fixed bolster 6 and the group 3 of walking to ensure that this electric mower can be nimble walk on the lawn, reduced simultaneously this electric mower effectively when cutting the trimming lawn the extrusion friction damage that the bottom of fixed bolster 6 caused the turf root on it to the lawn.

The use method and the working principle of the embodiment are as follows:

firstly, the fixing support 6 is adjusted to the height required by the lawn to be cut and trimmed through the elastic sleeve 5, then the driving mechanism 2 is started and the electric mower is pushed to the green lawn, meanwhile, the driving disc 10 is driven to rotate at high speed along with the driving mechanism 2 under the driving action of the driving shaft I7, the universal coupling 8 and the driving shaft II 9, the supporting ring I13 is driven to rotate along with the driving mechanism under the mutual pulling action of the three groups of cutting lines 11, the driven scraping disc 16 is driven to rotate at a reduced speed under the driving action of the friction ring 15, then when the electric mower is moved, the driven scraping disc 16 is firstly contacted with the lawn to be cut and trimmed, so that hard sundries such as small stones and the like on the moving path of the electric mower are firstly discharged to the edge position, and the hard sundries cannot be collided with the cutting lines 11 rotating at high speed, thereby effectively prolonging the service life of the cutting line 11;

when the electric mower excessively inclines due to potholes in the lawn, one end of the fixed support 6 is firstly contacted with the ground of the lawn to support the rotating part on the fixed support, and meanwhile, the elastic sleeves 5 in the corresponding direction are further compressed, so that the rotating part in the inner cavity of the fixed support 6 is prevented from being contacted with the soil of the lawn due to excessive inclination, and further the root of the lawn is prevented from being damaged.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
