Technical Field
[0001] The utility model relates to the technical field of pruning equipment, in particular to a lawn mower capable of pruning dead corners of lawns under trees. Background Art
[0002] Mowing the lawn at the appropriate time can inhibit its reproductive growth, promote tillering of the lawn, facilitate the elongation of creeping branches, improve the texture of the lawn, increase the density of the lawn, and inhibit the invasion of weeds. The lawn should be mowed based on the principle of obtaining a flat and neat lawn surface, while meeting the needs of lawn use for different purposes.
[0003] However, some lawns are planted with trees on both sides, which will hinder people's movement and the normal operation of the lawn mower, resulting in the lawn under the trees not being mowed, affecting the overall mowing effect of the lawn. Therefore, a lawn mower that can mow the dead corners of the lawn under the trees is proposed to solve the above problem. Utility Model Content
[0004] Based on the technical problem that existing lawn mowers cannot trim the lawn under trees, the utility model proposes a lawn mower which can trim the dead corners of the lawn under trees.

[0008] Through the above technical solution, by installing a dual-output shaft motor, the transmission shaft is driven to rotate, so that the pulley group fixedly mounted thereto is operated, driving the mowing spindle to rotate.

[0009] Preferably, the outer surface of the transmission shaft is fixedly mounted to the upper surface of the support plate via a bearing seat, and the outer surface of the transmission shaft is provided with first transmission wheels along a linear array.
[0010] Through the above technical solution, the transmission shaft and the support plate are fixedly installed by the bearing seat, so that the transmission shaft is fixed without affecting the rotation.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Reference Figure 1-Figure 3 A lawn mower that can trim the blind spots of lawns under trees includes a body 1. A support plate 2 is fixedly installed laterally on the upper surface of the mowing head of the body 1. A dual-output shaft drive source is fixedly installed on the upper surface of the support plate 2. The dual-output shaft drive source drives the mowing tool 3 in the body 1 to rotate through a pulley group 21.
[0028] In order to drive the transmission shaft 23 to rotate, the dual-output shaft drive source includes a dual-output shaft motor 22, and one end of the output shaft of the dual-output shaft motor 22 is fixedly installed with a transmission shaft 23 through a coupling. One end of the transmission shaft 23 is fixedly installed with the outer surface of the pulley group 21 through a coupling, and the outer surface of the pulley group 21 is fixedly installed with a mowing main shaft 24 through a coupling. The outer surface of the mowing main shaft 24 is rotatably connected to the outer surface of the body 1 through a bearing, and the outer surface of the mowing main shaft 24 is fixedly connected to the outer surface of the mowing tool 3 through a coupling. By installing the dual-output shaft motor 22, the transmission shaft 23 is driven to rotate, so that the pulley group 21 fixedly installed thereto is operated, thereby driving the mowing main shaft 24 to rotate. Through the rotational connection between the mowing main shaft 24 and the body 1, the mowing main shaft 24 will drive the mowing tool 3 fixedly installed thereto to rotate, which is used to mow the lawn.
[0029] In order to ensure that the transmission shaft 23 is fixed without affecting the rotation, the outer surface of the transmission shaft 23 is fixedly installed on the upper surface of the support plate 2 through a bearing seat. The outer surface of the transmission shaft 23 is distributed with first transmission wheels 25 along a linear array. The transmission shaft 23 is installed with the support plate 2 through the bearing seat, so that the transmission shaft 23 is fixed without affecting the rotation. By arranging multiple first transmission wheels 25 on the outer surface of the transmission shaft 23, the rotation of the transmission shaft 23 can drive the multiple first transmission wheels 25 to rotate, thereby driving the multiple auxiliary mowing blades 4 to rotate at the same time, and the mowing tool 3 and the auxiliary mowing blade 4 operate synchronously, thereby increasing the mowing range of the lawn mower.
[0030] In order to trim the lawn under the tree, an auxiliary trimming mechanism is provided on the upper front surface of the support plate 2 in a linear array along the length direction of the support plate 2. The auxiliary trimming mechanism includes an auxiliary trimming blade 4. The dual output shaft drive source drives the auxiliary trimming blade 4 through a gear set to trim the lawn under the tree.
[0031] The auxiliary mowing mechanism also includes a clamping plate 41, which is arranged on the upper surface of the support plate 2 along a linear array. A hole 42 is opened on the outer surface of the clamping plate 41, and a second transmission wheel 43 is slidably inserted at one end of the hole 42 through a bearing. The second transmission wheel 43 is meshed with the first transmission wheel 25, and the number of gears of the first transmission wheel 25 is greater than the number of gears of the second transmission wheel 43, thereby driving the auxiliary mowing blade 4 to rotate faster, thereby improving the mowing efficiency of the lawn under the tree. The clamping plate 41 is arranged on the upper surface of the support plate 2, so that the second transmission wheel 43 can be fixed on the support plate 2, and one end of the hole 42 is slidably inserted into the second transmission wheel 43 through the bearing. When the lawn mower does not need to trim the lawn under the tree, the auxiliary mowing blade 4 is stopped from rotating by pushing the second transmission wheel 43 to the other end of the hole 42. The first transmission wheel 25 is meshed with the second transmission wheel 43, so that the first transmission wheel 25 rotates while driving the second transmission wheel 43 to rotate, thereby rotating the auxiliary mowing blade 4.
[0032] In order to trim the lawn under the tree, a rotating rod 44 is fixedly installed at one end of the second transmission wheel 43 through a coupling. One end of the rotating rod 44 is fixedly installed to the outer surface of the auxiliary trimming blade 4 through a coupling. The second transmission wheel 43 and the rotating rod 44 are fixedly installed through the coupling. The second transmission wheel 43 drives the rotating rod 44 to rotate, so that the auxiliary trimming blade 4 fixedly installed with the rotating rod 44 rotates, thereby trimming the lawn under the tree.
[0033] In order not to affect the auxiliary mowing blade 4 in trimming the lawn under the tree, the length of the rotating rod 44 exceeds the length of the mowing head on the machine body 1, and the distance between adjacent clamping plates 41 is greater than the length of adjacent auxiliary mowing blades 4 when they are rotated to the horizontal direction. By making the length of the rotating rod 44 exceed the length of the mowing head on the machine body 1, the auxiliary mowing blade 4 can better trim the lawn under the tree. By making the distance between adjacent clamping plates 41 greater than the length of adjacent auxiliary mowing blades 4 when they are rotated to the horizontal direction, mutual interference between the auxiliary mowing blades 4 can be avoided, which will affect the mowing of the lawn under the tree by the auxiliary mowing blade 4.
[0034] By setting up a secondary mowing mechanism, the lawn under the tree is mowed, and the dual-output shaft motor 22 is started to drive the transmission shaft 23 to rotate. The multiple first transmission wheels 25 on the outer surface of the transmission shaft 23 will drive the second transmission wheel 43 engaged with it to rotate. The second transmission wheel 43 is fixedly installed with the rotating rod 44, and the second transmission wheel 43 will drive the rotating rod 44 to rotate, so that the secondary mowing blade 4 fixedly installed therewith rotates, thereby mowing the lawn under the tree. The rotation of the transmission shaft 23 will also drive the pulley group 21 fixedly installed therewith to operate synchronously, thereby driving the mowing tool 3 to rotate by driving the mowing main shaft 24 to rotate. The mowing tool 3 and the secondary mowing blade 4 achieve the effect of synchronous operation through the dual-output shaft motor 22, which increases the mowing range of the lawn mower while ensuring the integrity of the mowing of the entire lawn, solving the technical problem that the existing lawn mower cannot mow the lawn under the tree.
[0035] In order to enable the lawn mower to be operated horizontally, the outer surface of the body 1 is rotatably connected to a rotating wheel 5 through a bearing, and the outer surface of the axle on the rotating wheel 5 is rotatably connected to a U-shaped frame 51 through a bearing. The outer surface of the U-shaped frame 51 is fixedly installed with one end of the mowing main shaft 24 through a universal joint. The rotating wheel 5 is rotatably connected to the body 1, so that the rotating wheel 5 can rotate 360° to achieve the horizontal movement of the lawn mower. The U-shaped frame 51 is rotatably connected to the axle of the rotating wheel 5, and the U-shaped frame 51 is fixedly installed with the mowing main shaft 24 through the universal wheel, so that the rotating wheel 5 will not drive the body 1 to rotate while rotating.
[0036] By providing the rotating wheel 5, the lawn mower can be operated horizontally. The rotating wheel 5 is connected to the body 1 so that the rotating wheel 5 can rotate 360 degrees to achieve the horizontal movement of the lawn mower. The rotating wheel 5 is rotatably connected to the U-shaped frame 51 on the axle. The U-shaped frame 51 is fixed to the mowing spindle 24 through the universal wheel, so that the rotating wheel 5 will not drive the body 1 to rotate when rotating. With the support of the 360-degree rotatable wheel 5, the lawn mower can achieve simple mowing of the lawn under the tree.
[0037] Working principle: Start the dual-output shaft motor 22, drive the transmission shaft 23 to rotate, and make the pulley group 21 fixedly mounted thereto run, driving the mowing main shaft 24 to rotate. The mowing main shaft 24 will drive the pruning tool 3 fixedly mounted thereto to rotate. The rotation of the transmission shaft 23 will synchronously drive the first transmission wheel 25 fixedly mounted thereto to rotate, thereby driving the second transmission wheel 43 engaged therewith to rotate. One end of the second transmission wheel 43 is fixedly mounted with a rotating rod 44 through a coupling, so that the second transmission wheel 43 will drive the auxiliary pruning blade 4 to rotate by driving the rotating rod 44 to rotate, thereby achieving the effect of synchronous rotation of the pruning tool 3 and the auxiliary pruning blade 4, and mowing the lawn.
[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
