Abstract

The invention discloses a combined cutting tool of a mower. The combined cutting tool is characterized that a grass mower clamping rope device is added on a mower cutter; straight strip-shaped trimmer lines for shaping and forming are installed in a fixing and positioning manner; and a rigid cutting and flexible sticking manner is adopted to safely expand the working range of a conventional grass mower or grass mower cutter, and to ensure the safety of an operator of the mower. The combined cutting tool changes the situation that an existing push-type mower cutter can not work effectively at edges and corners of a work site, and a shoulder carrying mower or other approaches is required to carry out a secondary processing to finish working; and the combined cutting tool further solves the problem that although the working area of the shoulder carrying mower is in front of the operator, due to hand-held operations, the shoulder carrying mower is lack of balance, and the working area of a cutter is without safety guarantee due to the omission of a protective cover.

Description

A kind of mower gang tool

Technical field

The present invention relates to the garden instrument technical field, particularly a kind of mower gang tool.

Background technology

Existing mower, mainly contain two kinds of backpack and implementation formulas: the cutter of carrying out the formula mower generally all is mounted in the middle part of forward and backward two groups of bearing wheeds, when practical operation, because the factor of safety, cutter is all in protective cover, safety with the safeguard work personnel, and the undesirable condition that occurs to be existing implementation formula mower cutter can't carry out comprehensively effectively work to edge and the corner of work-yard, must carry out the secondary secondary process with modes such as shoulder carrying mowers, just can finish; Though the workspace of shoulder carrying mower is at operator's front end, owing to be hand-held working, lack of balance, the cutter workspace does not have safety guarantee owing to lack protective cover yet.

People-oriented advocating, and do not have any operation of safety guarantee paces of all can not keeping pace with the times today of harmonious society, and workman's working environment must obtain paying attention to perfect.

To the apparatus of garden instrument, handling safety and energy-conservation on, high-tech requirement renewal, that have more security performance has all been proposed.

Summary of the invention

The present invention realizes mechanically actuated better and the effective workspace of safety extension to implement providing a kind of mower gang tool.

In order to achieve the above object, the embodiment of the invention provides a kind of mower gang tool, it is characterized in that product increases mower card rope device at the mower cutter, with the vertical bar shape of fixing, the mode adapted typing of location, the solid shape rope of beating the grass, adding mode that flexibility impacts with rigidity cutting comes security extension have the working range of mower, mower cutter and guarantee mower operator's safety.

Compare with existing mower, mower cutting-tool engineering, the embodiment of the invention has following advantage and is:

1, the mower security performance increases, and it is convenient that the rope of beating the grass is changed.

2, utilize the centrifugal force of mower cutter air exercise straw rope to broaden the scope of work.

3, increase operating efficiency.

4, save artificial and the energy.

Embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, introduce a kind of mower gang tool of the embodiment of the invention in detail.

Cutter (4) at a kind of mower gang tool has knife-edge part on the cutter (6) (10), the two ends of cutter (4) respectively beat the grass the rope fixed part (2) (8), fixedly connected with power transmission shaft by being connected and fixed hole (5) cutter (4).

Beating the grass respectively has mower card rope spare (3) (9) corresponding guiding power-assisted firmware (13) on rope fixed part (2) (8).Mower card rope spare (3) (9) is gone up in the secondary cavity (12) I and II cavity cover (15), has the rope of beating the grass with auto-lock function to change hole (22) in the outside of I and II cavity cover (15); All the time the rope guide hole (18) of beating the grass that connects is arranged in the inboard of I and II cavity cover (15).

Front end at I and II cavity cover (15) respectively has by nip (25); One-level clamping key body (21) is respectively arranged in I and II cavity cover (15).

Press by nip (25), I and II cavity cover (15) is moved forward, inboard one-level clamping key body (21) compressing one-level cavity inner spring (20) acts on secondary clamping key body (17), secondary cavity inner spring (16) is oppressed, secondary clamping key body rope hole (19) crosswise fixed card power disappears, and secondary clamping key body rope hole (19) connects the effective aperture and enlarges.

Rope replacing hole (22) loses the auto-lock function to secondary clamping key body rope hole (19) because I and II cavity cover (15) when moving forward, is beaten the grass, and beating the grass rope is changed hole (22) and connected with secondary clamping key body rope hole (19).The rope (1) (7) of beating the grass is gone up power-assisted fixed guide hole (14) and is in place by beat the grass rope replacing hole (22), secondary clamping key body rope hole (19), the rope guide hole (18) of beating the grass, the rope guide shaft fixing unit (13) of beating the grass

Disappear when pressing nip (25) upward pressure, secondary cavity (12) interior secondary cavity inner spring (16) elastic force effect and mobile secondary clamping key body (17), the straw rope of fighting each other (1) (7) produces crosswise fixed card power because the perforation effective aperture reduces in secondary clamping key body rope hole (19).Hole (22) changed by the rope of beating the grass because the opposition of one-level cavity inner spring (20) is sealed self-locking to secondary clamping key body rope hole (19), to guarantee the fixing of rope (1) (7) of beating the grass.

The rope guide shaft fixing unit (13) of beating the grass is gone up the guiding assurance that power-assisted fixed guide hole (14) is air exercise straw rope (1) (7), and the broadening formation in the outside, power-assisted fixed guide hole (14) has increased the reliability and stability when beating the grass rope (1) (7) work.

Beating the grass respectively has three to be connected and fixed hole (11) on rope fixed part (2) (8), is connected and fixed three that hole (11) and cutter (4) go up in the rope fixed part join domain (23) (24) of beating the grass at two ends and is connected and fixed the hole coupling, and fix.

Describe by above embodiment, those skilled in the art can be well understood to process of the present invention, and still, the present invention is not limited thereto, any those skilled in the art can think variation all should implement protection scope of the present invention.
