[0003] After searching, the Chinese patent with publication number CN207124965U discloses an electric walking garden trimmer, a turntable is installed on one side of the front end of the self-propelled electric vehicle chassis, a replaceable trimmer head is installed at the front end of the cantilever assembly, and the tail of the cantilever assembly is installed on the turntable, and the self-propelled electric vehicle chassis includes a chassis frame. The beneficial effects of the utility model are: safe and reasonable structure, convenient use, energy saving, environmental protection, solving the labor intensity of manual back gasoline engine and manual trimming, and can accurately control the neatness of trimming, greatly improving work efficiency, and one person can operate more than 20 times more than ordinary trimming.

[0004] Although the above solution can solve the labor intensity of manual back-type gasoline engine and manual pruning, and can accurately control the neatness of pruning, it is difficult to conveniently replace the pruning blade of the pruning machine in the above patent. After long-term use of the pruning blade, the pruning blade itself will be damaged. Therefore, we provide a walking garden pruning machine to solve the above problems. Utility Model Content

[0026] The utility model embodiment provides a walking type garden trimmer.

[0027] See also Figure 2, including a pruning support frame 1 and a positioning and installation module 2, a first linkage roller 11 is fixedly arranged on the top of the positioning and installation module 2, the outer circumference of the first linkage roller 11 is transmission-connected to one end of a first transport crawler 12, and the other end of the first transport crawler 12 is transmission-connected to the outer circumference of a second linkage roller 13. The purpose of setting the first transport crawler 12 is to enable the first linkage roller 11 and the second linkage roller 13 to rotate at a rate of 1:2, thereby achieving a linkage effect, and driving the positioning and installation module 2 to rotate with the rotation of the first linkage roller 11.

[0028] See also Figure 2 The top of the second linkage roller 13 is fixedly connected to the bottom of the third linkage roller 14, the outer circumferential surface of the third linkage roller 14 is transmission-connected to one end of the second transport crawler 15, and the other end of the second transport crawler 15 is transmission-connected to the outer circumferential surface of the fourth linkage roller 16. The purpose of setting the second transport crawler 15 is to enable the third linkage roller 14 and the fourth linkage roller 16 to rotate at a rate of 1:2, and to keep the rotation speed of the third linkage roller 14 and the second linkage roller 13 consistent.

[0029] See also Figure 2 The top of the fourth linkage roller 16 is fixedly connected to the output shaft of the unidirectional DC motor 17, and the bottom of the unidirectional DC motor 17 is fixedly connected to the top of the positioning support plate 18. The unidirectional DC motor 17 is a prior art and will not be described in detail. The setting of the unidirectional DC motor 17 can provide sufficient power support for the movement of subsequent components.

[0030] See also Figure 1 The top of the positioning support plate 18 is fixedly connected to one end of the one-way electric control cylinder 20, and the bottom of the one-way electric control cylinder 20 is fixedly connected to the top of the pruning support frame 1. The one-way electric control cylinder 20 is a prior art and will not be described in detail. The setting of the one-way electric control cylinder 20 can provide a supporting linkage effect for adjusting the height of the pruned green plants.

[0031] See also Figure 1 , Figure 2 and Figure 5 A one-way roller 21 is fixedly arranged at the bottom of the trimming support frame 1, and a linkage bearing 22 is rotatably arranged inside the positioning support plate 18. The bottom of the linkage bearing 22 is fixedly connected to one end of a driving linkage plate 19, and the other end of the driving linkage plate 19 is rotatably arranged between the positioning and mounting module 2 and the first linkage roller 11. The purpose of setting the linkage bearing 22 is to control the rotation trajectory of the positioning and mounting module 2 by driving the linkage plate 19, and to make the positioning and mounting module 2 rotate with the linkage bearing 22 as the origin.

[0032] See also Figure 2The outer circumferential surface of the linkage bearing 22 is fixedly provided with the third linkage roller 14 and the second linkage roller 13. When the third linkage roller 14 and the second linkage roller 13 rotate, the linkage bearing 22 can rotate in place under the restriction of the positioning support plate 18.

[0033] See also Figure 3 and Figure 4 A second tough spring 9 is fixedly arranged inside the positioning installation module 2, and one end of the second tough spring 9 is fixedly connected to the positioning steel ball 10. The positioning steel ball 10 contacts the outer circumferential surface of the positioning linkage disk 4. The second tough spring 9 and the positioning steel ball 10 are tightly matched, and the elasticity of the second tough spring 9 itself is utilized to enable the positioning steel ball 10 to freely expand and contract. At the same time, through the contact with the positioning linkage disk 4, the stabilizing effect of the positioning linkage disk 4 is enhanced.

[0034] See also Figure 2 and Figure 3 The positioning and mounting module 2 is provided with a control groove 3, a positioning linkage disk 4 is inserted into the interior of the positioning and mounting module 2, and a positioning limiting column 5 is fixedly provided on the outer circumferential surface of the positioning linkage disk 4. The tight fit between the control groove 3 and the positioning limiting column 5 can effectively limit the positioning linkage disk 4 and ensure that the positioning linkage disk 4 rotates with the rotation of the positioning and mounting module 2.

[0035] See also Figure 2 and Figure 3 A pruning blade 6 is fixedly arranged at the bottom of the positioning linkage disk 4. The pruning blade 6 can be effectively rotated to perform top pruning on the green plants in the garden, thereby ensuring that the green plants in the garden maintain a uniform height. The top of the positioning linkage disk 4 contacts the bottom of the rubber barrier pad 8. A first tough spring 7 is fixedly arranged on the top of the rubber barrier pad 8. One end of the first tough spring 7 is fixedly connected to one side of the inner wall of the positioning installation module 2. The purpose of setting the first tough spring 7 is to utilize the elasticity of the first tough spring 7 itself to effectively promote the movement of the positioning linkage disk 4, thereby moving the positioning limit column 5 to the specified position in the control groove 3.

[0036] Working principle: the trimmer is mounted on both sides of the green plants, the one-way electric control cylinder 20 is started to work, the positioning support plate 18 is pushed to move, so as to adjust the trimming height of the green plants by the trimming blade 6, the one-way DC motor 17 is started to work, the second transport crawler 15 on the fourth linkage roller 16 is rotated, and the second linkage roller 13 under the third linkage roller 14 is driven to rotate, so that the second linkage roller 13 drives the first transport crawler 12 to move, and the positioning installation module 2 under the first linkage roller 11 is moved, and at the same time, the movement of the third linkage roller 14 and the second linkage roller 13 will also cause the linkage bearing 22 to rotate in the positioning support plate 18, so as to achieve the desired effect. The driving linkage plate 19 pushes the first linkage roller 11 to move, changing the position of the positioning and installation module 2, so that the pruning blade 6 can effectively prune the garden plants. When the pruning blade 6 needs to be replaced, the pruning blade 6 is pushed by external force to make the positioning linkage disk 4 slide in the positioning and installation module 2, so that the positioning limiting column 5 on the positioning linkage disk 4 rotates in the control groove 3, and the positioning linkage disk 4 is rotated again by external force, so that the positioning limiting column 5 translates in the control groove 3, and then, under the elastic characteristics of the first toughness spring 7 itself, the positioning linkage disk 4 is pushed out of the positioning and installation module 2, so that the effect of convenient replacement of the pruning blade 6 can be achieved.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
