[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0034] like Figure 1-Figure 12 As shown, a seedling pruning device for municipal greening includes a fixed rod 1 and a reciprocating rod 2 attached to the upper surface of the fixed rod 1, one side of the fixed rod 1 is fixedly connected to a fixed cutting knife 11, and the side of the reciprocating rod 2 close to the fixed cutting knife 11 is fixedly connected to a movable cutting knife 21, and the movable cutting knife 21 and the fixed cutting knife 11 reciprocate and staggered shearing movement to cut off the branches and vines entering the cutting area; the lower end of the fixed rod 1 is provided with a shifting rod 3, and the shifting rod 3 is rotated during the process of the movable cutting knife 21 reciprocatingly pruning the branches to the cutting area in front of the movable cutting knife 21 for cutting, and the front end of the shifting rod 3 can extend to the front end of the movable cutting knife 21 when it is extended forward, so that the branches in front of the cutting direction are gathered to the cutting knife area.

[0035] Specifically, a rotating block 4 is rotatably connected to the bottom of the fixed rod 1, and a guide block 5 is fixedly connected to the bottom of the rotating block 4. A guide groove 51 is opened in the guide block 5, and the strip rod 3 is inserted in the guide groove 51 and slides along the guide groove 51, and the rotating block 4 rotates unidirectionally under the drive of the one-way driving mechanism 6; a turntable 31 is rotatably connected to the middle position of the bottom of the strip rod 3, and the end of the fixed rod 1 is fixedly connected to a support 12, and the lower end of the support 12 is fixedly connected to a support plate 13 extending to the bottom of the strip rod 3, and a tension spring 14 is provided on the support plate 13, one end of the tension spring 14 is fixedly connected to the support plate 13 and the fixing point of the tension spring 14 and the support plate 13 is located on the side of the fixed rod 1 close to the fixed cutting knife 11, and the other end of the tension spring 14 is fixedly connected to the turntable 31, and the tension spring 14 pulls the strip rod 3 in the cutting direction through the spring tension. When the reciprocating rod 2 drives the moving cutting knife 21 to reciprocate and trim the branches through the reciprocating motion, the bar lever 3 is driven by the one-way driving mechanism 6, and the end of the bar lever 3 away from the guide block 5 rotates toward the inside of the moving cutting knife 21, and the branches close to the wall are pushed between the cutting knives so that the branches are cut. During the rotation of the bar lever 3, the tension spring 14 is stretched. After the toggle rod rotates 180°, the tension spring 14 is stretched to the longest, and the connecting line of the two ends of the tension spring 14 is parallel to the guide groove 51 on the guide block 5, so that the bar lever 3 slides and extends along the guide groove 51 in the cutting forward direction, and then the end of the bar lever 3 is attached to the wall and extends along the cutting forward direction. Under the action of the one-way driving mechanism 6, the bar lever 3 circulates inward to push the branches close to the wall toward the cutting knife position, and the bar lever 3 will not rotate along the wall in the cutting back direction.

[0036] Specifically, the one-way driving mechanism 6 includes a rack 61 fixedly connected to the inside of the reciprocating rod 2 and a gear 62 rotatably connected to the fixed rod 1.

[0038] Specifically, the lower end of the guide groove 51 is provided with an escape notch 52 for escaping the tension spring 14. Thus, when the bar lever 3 rotates to the side away from the movable cutting knife 21, the tension spring 14 can be reset and contracted through the escape notch 52 when the bar lever 3 is pulled by the tension spring 14 in the cutting forward direction.

[0039] Specifically, the end of the fixed rod 1 near the strip lever 3 is rotatably connected with a roller 15, and the roller 15 is in contact with the wall and rolls along the wall when in use. The roller 15 contacts the wall, so that the trimming device moves forward in the cutting direction.

[0040] Specifically, the outer side of the lever 3 is rotatably connected to a guide wheel 33, and the guide wheel 33 is used to abut against the wall so that the lever 3 and the wall can be rolled to avoid damage to the wall caused by the lever 3 during movement.

[0041] Preferably, when the line connecting the two ends of the lever 3 and the tension spring 14 is parallel, the end of the lever 3 facing the fixed cutting knife 11 is tilted outwardly, so that the end of the lever 3 extends to the outside of the fixed cutting knife 11 and fits against the wall, and the branches between the outside of the fixed cutting knife 11 and the wall are pulled to the inside of the fixed cutting knife 11 for cutting.

[0042] In the present invention, the fixed rod 1 is fixedly connected to a mounting plate 7 at one end away from the shifting rod 3. A chassis 71 fixedly connected to the fixed plate is sleeved on the outer side of the mounting plate 7. A driving motor 72 is arranged in the chassis 71.

A strip hole 23 perpendicular to the reciprocating rod 2 is opened on the driving block 22. The driving pin 74 is inserted in the strip hole 23. The driving motor 72 drives the lower rotating plate 73 to rotate, driving the driving pin 74 to rotate eccentrically, thereby driving the reciprocating rod 2 to reciprocate.

[0043] Specifically, a slide groove 24 is provided at the bottom of the reciprocating rod 2, and the slide groove 24 is arranged along the length direction of the reciprocating rod 2. A guide rail 16 is fixedly connected to the fixed rod 1, and the guide rail 16 is located in the slide groove 24 to limit the reciprocating rod 2, so that the reciprocating rod 2 slides along the guide rail 16.

[0044] The present invention provides a municipal greening seedling pruning device. When in use, the end of the fixed rod 1 close to the bar rod 3 is close to the wall to prune the top branches of the seedlings, and the driving motor 72 drives the rotating plate 73 to rotate, and the rotating plate 73 drives the driving pin 74 to rotate eccentrically, thereby driving the reciprocating rod 2 to reciprocate along the guide rail 16; the reciprocating rod 2 drives the moving cutting knife 21 to reciprocate and prune the branches through the reciprocating motion, and at the same time, the reciprocating rod 2 drives the rack 61 to reciprocate, and the rack 61 drives the rotating shaft 63 to rotate unidirectionally through the ratchet transmission, and the unidirectional rotation of the rotating shaft 63 drives the rotating block 4 and the guide block 5 fixedly connected to the rotating shaft 63 to rotate, and the rotation of the guide block 5 drives the guide The push bar in the groove 51 rotates unidirectionally, and the push bar rod 3 rotates from the outside to the inside, so that the branches close to the wall are gathered inwardly by the push bar rod 3, so that the branches close to the wall are pushed to the middle of the cutting knife and cut, thereby completing the pruning of the branches close to the wall; in the process of rotating inwardly, the push bar rod 3 is pulled by the tension spring 14, so that after rotating 180°, the push bar rod 3 is automatically pulled by the tension spring 14 and rebounds along the guide groove 51 on the guide block 5 and extends out from the other end of the guide groove 51, so that the falling action of the push bar rod 3 is automatically completed, so that the push bar rod 3 continuously rotates 180° in a cycle to gather the branches in the pruning forward direction inward for pruning.
