Description

Lawn mower

This creation refers to an improvement in the structural composition of a lawn mower, especially in the field of lawn mowers with improved cover for cutting elements.

According to the conventional hand-held shoulder mower, a power source (generally a power motor) is arranged above the grip bar, and the lower end of the grip bar is provided with a knife seat, and the knife seat is pivotally connected to the cutting component (such as a blade and a tendon) Rope, cutter head, etc.), the power source transmits power to the cutting element, causing it to rotate to achieve the purpose of removing weeds. To achieve body balance and labor saving, a grip handle can be set at a specific position of the grip bar and/or Shoulder straps. However, when mowing is carried out, it is still necessary to hold the force, and the operation is controlled by different directions such as left and right or front and rear. Therefore, under long-term use, the body is relatively tired, so the industry has a labor-saving hand-held mowing. The machine appears, this can be as in the patent case No. M469735, M497431 and other patents in China, which mainly provide support frame and frame body on both sides of the knife seat and the cutting component, and use the support frame and the frame body when mowing is implemented. Glide to the ground, and achieve the goal of labor-saving mowing.

According to the above, since the support frame and the frame body are all open-type frames, when the mowing is carried out, the support frame and the frame body have almost no blocking function for stones, gravel, hard objects and the like on the ground, so that Cutting elements are often touched and the stones, gravel, and hard objects fly out. It is extremely dangerous. In addition, the weeds after cutting will also be scattered everywhere or stacked. The upper part of the knife seat and the cutting element increases the danger and difficulty of the operator, so it is necessary to improve it.

In view of the above-mentioned lack of the learners, the creator first thought of standing in the position of the operator. Under the premise of labor saving, the mower can eliminate stones and weeds from scattering and avoiding accumulation in the knife seat. Above the cutting element, we can break through the defects of the existing one and eliminate the lack of it. Therefore, the creator has improved this goal and created the original creation through continuous conceiving.

Therefore, the technical structure adopted by the present invention means that the lawn mower includes at least one grip bar, a power source, a knife seat, a cutting component and a cover, wherein the power source is connected to one end of the grip bar. The knife seat is connected to the lower end of the holding rod, and the knife seat is pivotally connected to the cutting element, and the power source is coupled to the cutting element to enable the cutting element to rotate. In addition, the cover is coupled to the knife seat and can shield the cutting element The main improvement is that the cover is composed of a plurality of warp struts, and a hole is formed in the center of the upper end of the cover to provide a seat piercing set, and the hole has a hole ring at the periphery thereof, and the ring ring is The blade holder is assembled, and the periphery of the warp struts is each a curved arc segment, and the bottom ends of the curved arc segments each extend inwardly by an inner extending portion, and the inner extending portion extends below the cutting element. According to this, the weeds can be cut off from the warp strut into the underside of the cover, and the surrounding stones can be blocked by the curved section of the warp strut to avoid damage to the cutting elements, and The inner extension of the line strut can be touched to achieve the goal of labor-saving operation.

Secondly, the cover is fixed at least one weft ring rod laterally above the curved section of the warp strut, so that the cut weeds can be moved from the weft loop pile to the side to avoid accumulation in the seat , above the cutting element.

Furthermore, the cover is fixed with a bottom ring at the end of the inner extension of the warp struts to enhance the structural strength.

Moreover, the inner extension of the warp strut is horizontal. In addition, the grip bar is provided with a grip handle.

Therefore, the main purpose of the present invention is that the cover is disposed as a mesh cover and shielded above the blade holder and the cutting element, so that the stone can be blocked on the outside of the cover to avoid damage to the cutting element and the weed can be covered by the cover. The cover's warp struts enter and are cut off, and the cover has a weft ring rod, so that the cut weeds are moved to the side by the weft loop pile stack to avoid accumulation on the knife seat and the cutting element.俾 to exclude the lack of existing ones.

The second picture is a three-dimensional exploded view of the creation.

The third picture is a side view of the planar combination of the creation.

The fourth picture is a reference diagram of the implementation state of the present creation.

Referring to the first figure, the "mower" of the present invention mainly comprises a gripping rod 1, a power source 2, a holder 3, a cutting element 4 and a cover 5. among them:

The grip bar 1 is a rod body which is provided with a grip handle 11.

The power source 2 can be a power motor that is connected to the upper end of the grip bar 1 .

The seat 3 is connected to the bottom end of the grip bar 1.

The cutting element 4 is pivotally connected to the bottom end of the seat 3 and receives power from the power source 2 to be swung. The cutting element 4 can be a blade, a tendon rope, a cutter head, etc.

The cover 5, see the second and third figures, is mainly fixed by a plurality of warp struts 51 to form a net cover, wherein the cover 5 has a hole 52 at the center of the upper end and a hole ring at the periphery of the hole 52. The hole 52 is provided with a seat 3, and the ring 53 is configured to be screwed to the seat 3, and the periphery of the warp rod 51 is a curved section 511, and the curved section 511 is The bottom ends each extend an inwardly extending section 512, and the inwardly extending section 512 extends below the cutting element 4, and the inwardly extending section 512 can be horizontal. Moreover, the cover 5 is laterally fixed with at least one weft ring rod 54 above the curved section 511 of the warp support 51 (in the figure, only one weft ring rod is taken as an example), and further, the cover 5 is in the warp. A bottom ring 55 is secured to the end of the inner extension 512 of the strut 51 to provide structural strength at the inner extension 512.

When implemented in a configuration, as shown in the fourth figure, the operator holds the grip handle 11 of the grip bar 1 and makes the inner extension 512 of the cover 5 contact the ground, after which the power source 2 is activated to cause the cutting element 4 slewing, and swinging operation in different directions, such as left and right or front and rear, so that the labor-saving mowing operation can be performed, and when implemented, the weed 6 can be accessed from between the warp struts 51 and under the cover 5 The cutting element 4 is cut, and the surrounding stone 7 is blocked by the curved section 511 of the warp strut 51, and the cutting element 4 can be prevented from being damaged, and then the cut weed 6 is wefted by the weft ring 54 The stack is moved to the side to avoid accumulation on the holder 3, above the cutting element 4.

According to the above configuration and implementation description, it can be confirmed that the present invention can completely exclude the cutting member 4 from touching the stone 7 after the structural improvement of the cover 5, and the existing person in which the weed 6 is deposited on the seat 3 and the cutting member 4 after cutting. Lack of Use, progress, and enhance the competitiveness of the market.

In summary, when we know that the novel structure created in this case has industrial utilization, novelty and progress, it is in line with the new patent requirements. However, the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, the equal changes and modifications made by the patent application scope of this creation are covered by the scope of the creation patent.
