Description

Mowing saw blade with straw rolling prevention mechanism

Technical Field

The utility model relates to a mowing apparatus field specifically is a saw bit of mowing with prevent rolling up grass mechanism.

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.

At present, the more mowing saw blades are usually provided with sawteeth on the saw blades, the mowing saw blades are directly matched with mounting holes to be mounted on a mower to work, only weeding work can be carried out, and when some longer plant roots and stems are treated, plants are extremely easy to be rolled into a machine shaft, so that the service life and the operation efficiency of the machine are influenced.

Disclosure of Invention

An object of the utility model is to provide a have and prevent roll up grass mechanism saw bit of mowing, can prevent effectively that disconnected grass from being drawn into the machine to improve the operating efficiency, prolong machine life.

The utility model provides a following technical scheme: the utility model provides a saw bit of mowing with prevent rolling up grass mechanism, includes saw bit main part and mounting hole, the sawtooth has evenly been seted up in proper order to the periphery of saw bit main part, the center in saw bit main part is seted up in the mounting hole, the sword groove has evenly been seted up in proper order in the saw bit main part, be equipped with the blade in the saw bit main part of sword groove one end.

Preferably, the surface of the saw blade main body is provided with a reserved hole.

Preferably, the blade is directly stamped from a portion of the saw blade body.

Preferably, open slots are formed in the saw blade main bodies at two ends of the bottom of the blade.

Preferably, one side of the blade is a cutting edge and is clockwise.

Preferably, the number of blades is at least four.

Preferably, the blade has a projection angle of 20 ° ~ 30 °.

The utility model discloses a technological effect and advantage:

1. The utility model effectively cuts the plant when the blade formed by punching the saw blade works, avoids the plant rootstock and grass cutting from being drawn into the machine, prolongs the service life of the machine when doing annual national operation efficiency;

2. The blades are arranged at a certain angle on the saw blade, so that the saw blade and the blades form two cutting surfaces when in work, air flow is formed between the two cutting surfaces, dust and broken grass are blown out of the saw blade, the cutting efficiency is improved, and the phenomenon that the saw blade is infected with excessive grass scraps and then influences the cutting efficiency is avoided.

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 a saw bit of mowing with prevent rolling up grass mechanism as shown in fig. 1-3, including saw bit main part 1 and mounting hole 6, saw bit main part 1's periphery has evenly seted up sawtooth 2 in proper order, mounting hole 6 sets up in the center of saw bit main part 1, knife groove 5 has evenly seted up in proper order on the saw bit main part 1, be equipped with blade 4 on the saw bit main part 1 of knife groove 5 one end, preformed hole 3 has been seted up on the surface of saw bit main part 1, alleviates the weight of saw bit main part 1, can avoid excessively being infected with raise dust and plant residue simultaneously during the work to make the effect of mowing receive the influence, blade 4 is formed for the direct punching press of a part of saw bit main part 1, is convenient for produce, and connects the steadiness and has ensured, set up open slot 7 on the bottom both ends saw bit main part 1 of blade 4, can reduce the area of being connected of blade 4 and saw bit main part 1, gives blade 4 a reserved space when the cutting, is convenient for blocking tendril etc. in 7 with this increase cutting efficiency, one side of blade 4 is cutting edge 41 and is the setting up each other, increase the cutting efficiency, the cutting blade 4 can be carried out the most by the cutting blade 2 and the cutting edge, and the most convenient for the cutting edge is carried out the most, and can be carried out the cutting effect of the cutting edge, two cutting edge 2, and can be carried out the cutting edge, and can be carried out the most convenient to form the cutting edge, and can be convenient for the root and the root system, two cutting edge, the cutting edge of the cutting effect of the cutting edge.

The working principle is that the saw blade main body 1 is arranged on the cutting machine to work by utilizing the mounting hole 6, and when the machine is started, the four upturned blades 4 can rotate along with the saw blade main body 1 and are used for cutting some longer plants such as grass, rootstalks and the like which are easy to be drawn into the machine; meanwhile, the rotating surface of the upturned blade 4 can be staggered with the rotating surface of the saw blade main body 1, so that stronger air flow is formed, the grass-cutting is blown away through the air flow, the grass-cutting is prevented from being involved in and options are prevented in two directions, the working efficiency is improved, and the service life of the machine is prolonged.

When this saw bit of production, blade 4 forms for direct punching press on the saw bit main part 1, and the connection stability of the production of being convenient for and blade 4 also ensures to some extent, and blade main part 1 can dock each other through sword groove 5 and blade 4 on other saw bit main parts 1 simultaneously and pile up, is convenient for place in order to transport work.

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.
