Abstract
Description
Technical Field
[0001] This utility model relates to the field of pruning device technology, specifically to a transverse translational pruning assembly and a pruning machine. Background Technology
[0002] Reciprocating blade trimmers are commonly used in garden pruning, and are often available in handheld and push-type models. If a handle is installed on the housing of the trimming component, it becomes a handheld trimmer, which can be carried by hand to perform garden pruning operations such as weeding and brush cutting. In common handheld trimmers, the blades are usually connected to the housing at the end. This configuration is not suitable for docking with a handcart after the handle is removed. The trimming components in handheld trimmers are not interchangeable with those in push-type trimmers, and improvements are needed. Utility Model Content
[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:
[0004] This application discloses a transverse translational trimming assembly, including a housing and a drive mechanism, an eccentric transmission mechanism, and a reciprocating trimming blade disposed on the housing. The drive mechanism drives the corresponding blade in the reciprocating trimming blade to move through the eccentric transmission mechanism. The reciprocating trimming blade is arranged transversely relative to the housing. The middle of the side of the reciprocating trimming blade is connected to the housing, and its corresponding blade is connected to the eccentric transmission mechanism.
[0005] The placement direction of the reciprocating trimmer blades and the docking position between the side and the middle of the machine housing and the eccentric transmission mechanism are limited. When in use, a handle can be installed on the machine housing to push the grass out in advance by hand. The machine housing can also be combined with a handcart to push the grass out in advance, making the usage more versatile. It can be used in both hand-held trimmers and handcart trimmers.
[0006] Furthermore, a notch is provided on the front of the housing, and the middle of the side of the reciprocating trimming tool is connected to the housing wall of the notch. The middle of the side of the corresponding blade in the reciprocating trimming tool is connected to the output end of the eccentric transmission mechanism of the notch. The notch is added to better connect the reciprocating trimming tool and facilitate assembly.
[0007] Furthermore, the top of the housing is provided with mounting holes for external connection, and the bottom of the housing is provided with multiple protrusions at intervals for support, such as connecting to handles or handcarts through connection holes, to facilitate connection, increase wear resistance, and facilitate the use of handcarts.
[0008] Furthermore, the length extension direction of the protrusion is perpendicular to the length direction of the reciprocating trimming tool, and the axial direction of the mounting hole is parallel to the length direction of the reciprocating trimming tool.
[0009] Furthermore, the reciprocating trimming tool includes a fixed plate 1 and a fixed plate 2 connected at intervals, and a blade 1 and a blade 2. The blade 1 and blade 2 are stacked between the fixed plates 1 and 2 in the longitudinal direction and slide in cooperation with the fixed plates 1 and 2 in the length direction. The upper fixed plate 1 is connected to the machine housing, and the blade 1 and blade 2 are connected to the eccentric transmission mechanism at the middle of the side.
[0010] Furthermore, the blades one and two have serrations on both sides of their bodies, and a notch two for connection is provided in the middle of the side of the blades one and two. The notch two has a connecting end that protrudes inward and outward, and a connecting groove is provided at the connecting end. The output end of the eccentric transmission mechanism is inserted into the connecting groove for fixation. The notch two is added to reserve space for the reciprocating movement of the blade one, so as to avoid the influence of the machine housing. The blade is fixed to the eccentric transmission mechanism through the connecting groove for easy disassembly and replacement, which facilitates subsequent maintenance operations.
[0011] Furthermore, it also includes fasteners, which connect the first and second fixing plates at intervals and pass through the waist holes formed along the length of the first and second blades. Some fasteners are connected to the housing. The fasteners facilitate the connection between the two fixing plates. The fasteners pass through the waist holes to avoid affecting the reciprocating motion of the blades. Common fasteners include bolts.
[0012] Furthermore, the eccentric transmission mechanism includes a gear transmission mechanism, a connecting plate, and a drive block. The gear transmission mechanism is connected to the drive mechanism, and two drive blocks are eccentrically connected to the output end of the gear transmission mechanism and are distributed vertically along the longitudinal direction. The connecting plates are stacked vertically, and the corresponding drive blocks are located in the grooves of the corresponding connecting plates. The end of the connecting plate has a protruding locking block that engages with the connecting groove of the corresponding blade to connect them. Under the transmission of the gear transmission mechanism, the drive mechanism drives the drive block to rotate eccentrically, and the drive block drives the connecting plate to swing left and right synchronously, causing the blade connected to the connecting plate to reciprocate. By swinging the connecting plate, the corresponding blade is driven to reciprocate. The saw teeth of the two blades cut weeds and other materials in the reciprocating cross motion.
[0013] Furthermore, the connecting groove includes a cavity recessed on the top or bottom surface of the connecting end. An inlet communicating with the outside is formed on the peripheral wall of the cavity. The width of the inlet is less than the length of the cavity. The locking block includes a connector and a connected protrusion. The length of the protrusion is greater than the width of the inlet. After the locking block mates with the connecting groove, the protrusion is embedded in the cavity and the connector extends out from the inlet. During installation, the locking block can be directly inserted into the connecting groove. The protrusion helps to restrict detachment, making installation and disassembly more convenient.
[0014] The second aspect of this application discloses a trimming machine, including the trimming components described above.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model improves the placement direction of the reciprocating trimmer blade and the docking position with the machine housing and eccentric transmission mechanism, making it versatile in use and applicable to handheld trimmers and trolley trimmers. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] Example 1
[0031] In this example, the transverse translational trimming assembly includes a housing 1 and a drive mechanism 2, an eccentric transmission mechanism 4, and a reciprocating trimming blade 3 mounted on the housing 1. Figure 1 , Figure 2 , Figure 6 As shown, in this example, the drive mechanism 2 is like a drive motor, which is fixed at the top of the housing 1. The output end of the drive mechanism 2 extends into the cavity through a formed hole at the top of the housing 1. The eccentric transmission mechanism 4 is located in the cavity of the housing 1. The eccentric transmission mechanism 4 is connected to the output end of the drive mechanism 2. The output end of the eccentric transmission mechanism 4 is connected to the corresponding blade in the reciprocating trimming tool 3 on the front of the housing 1, so that the drive mechanism drives the corresponding blade in the reciprocating trimming tool to move through the eccentric transmission mechanism.
[0032] In this example, as Figure 1 As shown, the reciprocating trimmer 3 is horizontally positioned relative to the housing 1. The middle of the side of the reciprocating trimmer 3 is connected to the housing 1, and its corresponding blade is connected to the eccentric transmission mechanism 4. In use, a handle can be attached to the housing to form a handheld trimmer; the handle can be held to push it forward for weeding. Alternatively, the housing can be attached to a handcart to form a push-type trimmer; the handcart can be started and pushed forward for weeding, offering diverse usage options. To facilitate the attachment of handles, etc., in this example, mounting holes 100 for external connections are formed on the top of the housing 1. Figure 2 , Figure 9 As shown, the mounting hole 100 extends laterally relative to the housing 1, allowing for the connection of handles and trolleys. When connecting a trolley, to reduce wear on the housing, in this example, multiple protrusions 101 for support are formed at intervals at the bottom of the housing 1. The protrusions are elongated, and preferably, the length of the protrusions extends perpendicular to the length direction of the reciprocating trimming tool, while the axial direction of the mounting hole is parallel to the length direction of the reciprocating trimming tool.
[0033] For ease of connection, such as Figure 2As shown, in this example, a recessed notch 102 is formed at the lower front of the housing 1, and the middle of the side of the reciprocating trimming tool 3 is connected to the housing wall of the housing 1 at the notch 102. Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, in this example, the reciprocating trimmer 3 includes a fixed plate 31 and a fixed plate 32 connected at intervals, and blades 34 and 33. The fixed plates 31 and 32 are connected longitudinally at intervals by fasteners 35, such as common bolts and matching nuts. Blades 34 and 33 have serrations 40 formed on both sides of the body. Multiple slotted holes 39 are formed at intervals along the length direction at the middle of the top surface of the blades 34 and 33. The slotted holes extend along the length direction of the blades. Blades 34 and 33 are stacked longitudinally and installed in the space between the fixed plates 31 and 32. Blades 34 and 33 slide with the fixed plates 31 and 32 along the length direction. Specifically, the bolts in the fasteners pass through the slotted holes of the lower fixed plate 31 and the corresponding blade and connect to the upper fixed plate 32. The slotted holes allow blades 34 and 33 to slide relative to the fixed plates 31 and 32. The connection between the reciprocating trimmer 3 and the notch 102 is as follows: Figure 1 As shown, the bolt in the middle fastener 35 extends into the hole in the housing wall above the notch 1 and is fixed with a bolt.
[0034] To facilitate the connection between the blade and the eccentric drive mechanism, such as Figure 3 , Figure 5 , Figure 9 As shown, in this example, blade 1 34 and blade 2 33 are recessed at the middle of the side to form a notch 2 36 for connection. The blade body inside the notch 2 36 is protruding at the side to form a connecting end 37, which is like a common plate. The connecting end 37 is formed longitudinally with a connecting groove 38. The output end of the eccentric transmission mechanism 4 extends from the notch 1 102 and is inserted into the connecting groove 38 to be fixed as one unit.
[0035] like Figure 6 , Figure 7 , Figure 8As shown, in this example, the eccentric transmission mechanism 4 includes a gear transmission mechanism, a connecting plate 44, and a drive block 46. The gear transmission mechanism includes a first gear 41, a second gear 42, and a third gear 43 that mesh with each other. The first gear 41 is fixed to the output end of the drive mechanism 2. The first gear 41 meshes with the upper gear ring of the second gear 42 below the drive mechanism. The third gear 43 meshes with the lower gear ring of the second gear 42. The drive block 46 is fixed longitudinally on the gear shaft of the third gear 43. The drive block 46 is eccentrically connected to the gear shaft. The two connecting plates 44 are stacked on top of each other and both connecting plates 44 have grooves formed on them. For example, the upper drive block 46 is in the groove of the upper connecting plate 44, and the lower drive block 46 is in the groove of the lower connecting plate 44. The third gear rotates and drives the connecting plate to swing left and right through the drive block, so that the end of the connecting plate is inserted into the connecting groove, thereby synchronously driving the corresponding blade to reciprocate left and right. The saw teeth of the two blades cut weeds and other materials in the reciprocating cross motion.
[0036] To facilitate snap-fitting, in this example, the connecting groove 38 includes a recessed cavity 381 formed on the top or bottom surface of the connecting end. For example, in this example, a through hole is formed longitudinally at the connecting end, with the through hole serving as the cavity 381. An inlet 382, communicating with the outside, is formed at the peripheral wall of the cavity 381 relative to the blade body. The width of the inlet 382 is less than the length of the cavity 381. A latching block 45 protrudes outward at the end of the connecting plate 44. The latching block 45 includes a connector 452 and a connected protrusion 451, both generally T-shaped. The length of the protrusion 451 is greater than the width of the inlet 382. Figure 9 As shown, when the locking block 45 is engaged in the connecting groove 38, the protrusion 451 is embedded in the groove cavity 381 and the connector 452 extends out from the inlet 382. The protrusion helps to restrict disengagement. The detachable assembly configuration facilitates subsequent replacement of blades, etc.
[0037] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
