Abstract

The invention discloses a cutting head which is used for cutting lawn and comprises a spool, a winding clamp and cutting wires. The winding clamp is accommodated in the spool, the cutting wires are wound on the winding clamp, the spool is provided with a transparent window, and the cutting wires can be observed via the transparent window. The cutting head has the advantage that residual volumes of the cutting wires can be observed by an operator via the transparent window.

Description

Cutting head

Technical field

The present invention relates to a kind of cutting head.

Background technology

Traditional cutting head comprises a line cup.Form a cutting chamber of holding cutter sweep in the line cup.Being wound around one or more line of cut on cutter sweep can be used for cutting the grass on a lawn.Line of cut is constantly wearing and tearing in cutting process.After the line of cut wearing and tearing, need feeding to maintain certain-length for work.Line of cut finally can run out, so the user need to change line of cut.But, because line of cut is wrapped in cutting head inside, except taking whole cutting head apart, the user does not also have other ways to check that the interior roll bobbin that stores line of cut is to determine the residual volume of line of cut at present.

Therefore, on the basis that prior art has been carried out concentrating on studies, the inventor provides a kind of facility to check the cutting head of line of cut residual volume.

Summary of the invention

The purpose of the invention is: provide a kind of facility to check the cutting head of line of cut residual volume.

For achieving the above object, the invention provides a kind of cutting head, for cutting lawns, comprise the line cup, be contained in the winding clamp in the line cup and be around in the line of cut on winding clamp, the line cup is provided with for observing the transparency window of line of cut.

Compared with prior art, the present invention at least has following beneficial effect:

The operator can observe by transparency window the residual volume of line of cut.

The accompanying drawing explanation

Fig. 1 is the schematic diagram of cutting head of the present invention.

Fig. 2 is the decomposing schematic representation of Fig. 1.

Fig. 3 is the schematic diagram of the line of cut in cutting head of the present invention.

Embodiment

As depicted in figs. 1 and 2, a kind of cutting head 100, can be installed to cutting tool lawn is pruned.Cutting tool comprises mower, mower or trimmer.

Cutting head 100 comprises line cup 1, is contained in winding clamp 2 and line of cut 3 in line cup 1.

Line cup 1 comprises cup 11 and end cap 12.Cup 11 is driven by a motor rotation.General and shaft mechanical motor of cup 11 is fixed together.The inner cutting chamber of holding winding clamp 2 that forms of cup 11.End cap 12 snaps together for preventing that winding clamp 2 from coming off with cup 11.Line cup 1 is provided with the wire hole passed for line of cut 3.

Winding clamp 2 is contained in cutting chamber.Winding clamp 2 comprises the roll in the middle of being arranged at and is positioned at the edge at roll two ends.Winding clamp 2 line cup 1 rotation relatively.

Refer to Fig. 1 to Fig. 3, line of cut 3 is for cutting lawns.Line of cut 3 is wound in the space surrounded between roll and edge.Line of cut 3 one ends are fixed in winding clamp 2, and the other end is free state from extending in wire hole.During relative line cup 1 rotation of winding clamp 2, line of cut 3 carries out feeding.

Line of cut 3 is provided with the mark of the length that indicates line of cut 3.Line of cut 3 comprises mark zone and unmarked district, and mark is positioned at mark zone.

Mark can be sequence number, also can make actual numeral.When the mark that exposes wire hole surpasses certain limit, mean that the residual volume of line of cut 3 is less than limiting value.The operator should change line of cut 3 in time, to prevent line of cut 3 deficiencies, can not act on.

In order to highlight mark, mark zone is different from the color in unmarked district.Perhaps, mark zone is different from the diameter in unmarked district.Perhaps, mark zone is different from the shape in unmarked district.

Further, for the ease of observing mark, cup 11 is provided with transparency window 10.It is clearer that the operator can observe the residual volume of line of cut 3 like this.More excellent, transparency window 10 is set to have the convex lens of optical amplifier mark function.

Further, for the operating efficiency of line of cut 3 is provided, windage while reducing line of cut 3 rotation, line of cut 3 is provided with spiral type groove 31.Noise when this spiral type groove 31 can reduce line of cut 3 rotation simultaneously.The pitch W of spiral type groove 31 equals the interval that arranges of mark.Like this can find out a series of mark according to the shape of spiral type groove 31.

Claims

1. a cutting head, for cutting lawns, comprise the line cup, be contained in the winding clamp in the line cup and be around in the line of cut on winding clamp, and it is characterized in that: described line cup is provided with for observing the transparency window of line of cut.

2. cutting head according to claim 1, it is characterized in that: described transparency window is convex lens.
