Description

Anti-drop type saw bit of mowing

Technical Field

The utility model relates to a grass cutting device field specifically is an anti-drop type saw bit of mowing.

Background

The mowing saw blade is generally used for being assembled on a mower to perform mowing, various operations such as miscellaneous trees, shrubs and the like, and is a common tool in the aspects of gardens and greening.

And at present use more saw bit of mowing usually for seting up the sawtooth on the saw bit, the work is carried out on the lawn mower in the installation of direct fit mounting hole, only can carry out ordinary weeding work, in some unexpected circumstances take place, for example when the hidden stone in the weeds or carelessly touch some relatively harder barriers when weeding beside the building, if joint strength is not good or tool bit material quality is not good, very easily cause serious damage to the saw bit, the tool bit drops even to cause the injury to peripheral people or animal.

Disclosure of Invention

An object of the utility model is to provide an anti-drop type saw bit of mowing, structural design is reasonable, increases the fixed effect of tool bit, avoids leading to the tool bit to drop because of the accident and influences the installation effect of saw bit base member even, increases the security.

The utility model provides a following technical scheme: the utility model provides an anti-drop type saw bit of mowing, includes saw bit base member, mounting hole and L type blade, the periphery of saw bit base member evenly is equipped with the sawtooth in proper order, L type slot has been seted up on the surface of sawtooth, L type blade all sets up the L type slot internal weld on the sawtooth, the center department at the saw bit base member is seted up to the mounting hole.

Preferably, the surface of the saw blade matrix is uniformly provided with reserved holes.

Preferably, the preformed holes are at least provided with five groups and are sequentially and uniformly arranged according to the pore size.

Preferably, the L-shaped blade is capable of engaging with an L-shaped slot provided on the saw tooth.

Preferably, the L-shaped blade rotates from a counter-clockwise direction during operation.

Preferably, the diameter of the saw blade body is 254 ~ 256mm, and the edge thickness is 1.9 ~ 2.1.1 mm.

The utility model discloses a technological effect and advantage:

1. the utility model discloses with the tool bit outside independent of the sawtooth, use the welded mode to combine it, make during operation, when the saw bit accident touched the hard thing, the tool bit was pressed in advance and is bounced open, avoided the sawtooth to collide directly, thereby influenced the installation stability of saw bit, improved the security;

2. the L-shaped cutter head is embedded into the side face of the saw blade base body and firmly welded on the base body, when the L-shaped cutter head is stressed, the tail end of the L-shaped cutter head can be clamped with the slot on the saw teeth, and the stability of the cutter head is further improved by matching with the welding effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides an anti-drop type mowing saw blade as shown in figures 1-3, which comprises a saw blade base body 1, a mounting hole 2 and an L-shaped blade 5, wherein sawteeth 3 are evenly arranged on the periphery of the saw blade base body 1 in sequence, L-shaped slots 31 are arranged on the surfaces of the sawteeth 3, the L-shaped blade 5 is arranged in the L-shaped slots 31 on the sawteeth 3 for welding, in particular, the L-shaped blade 5 can be clamped with the L-shaped slots 31 on the sawteeth 3 so as to carry out subsequent welding work, meanwhile, the L-shaped blade 5 can be more stable under the structural influence without influencing the connecting effect due to common collision, and the L-shaped blade 5 can rotate in the counter-clockwise direction during working, so that the tail end of the L-shaped blade 5 can fully hook the L-shaped slots 31 when the L-shaped blade 5 is pressed, and the connecting relation of the L-shaped blade 5 is more stable by matching with the welding relation, place the tool bit and drop, the center department that saw bit base member 1 was seted up in mounting hole 2 is concrete, preformed hole 4 has evenly been seted up on the surface of saw bit base member 1, alleviates the weight of saw bit base member 1, and the saw bit during operation can avoid excessively being infected with raise dust and plant residue rhizome simultaneously to make the effect of mowing receive the influence, just preformed hole 4 is equipped with five groups at least, and according to aperture size align to grid in proper order, has further improved dust removal effect, is convenient for subsequent cleaning work when avoiding the grass bits to be infected with.

Specifically, the diameter of the saw blade base body 1 is 254 ~ 256mm, the blade thickness is 1.9 ~ 2.1.1 mm, the specification can be guaranteed to be suitable for most cutting machines, and large-scale production is facilitated.

The working principle is that the saw blade base body 1 is assembled on the cutting machine through the mounting hole 2, the machine is started to enable the saw blade base body 1 to rotate, the tail end of the L-shaped blade 5 has a hooking effect in the period, the grandma hooks the saw teeth 3, and the L-shaped blade 5 is stably connected to the saw blade base body 1 under the welding effect, so that the effect of placing a cutter head to fall off is achieved; when the saw bit accident touched hard thing in the work, was suppressed in advance by L type blade 5 and is opened by the bullet, avoided 3 direct collisions of sawtooth to influence the installation stability of saw bit base member 1, improved the safe effect, and L type blade 5 also can increase the cutting efficiency to weeds with the cooperation of sawtooth 3.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
