Description

A kind of anti-seizing mechanism of weeding

Technical field

The utility model is related to weeding machine technical field, the anti-seizing mechanism of weeding of specifically a kind of weeder.

Background technology

Now with the development of automatic technology, weeding work is replaced traditional craft by the weeder automated Weeding works, and the weeder of automation usually carries out grass cutting action by the cutterhead rotation in driven by engine shaft, but except In the process of grass, the weeds cut off can rotate with the rotation of work cutterhead, and weeds are easy to be wound into shaft due to rotating, It as weeds the more twine the more more, the more twines the more solid, the resistance of shaft, or even the parts of damage weeder can be increased, influence weeding The normal weeding of machine works.

Invention content

Technical problem to be solved in the utility model is：There is provided it is a kind of effectively weeds can be avoided to wind, reduce resistance, carry The anti-seizing mechanism of weeding of high working efficiency.

Technical solution used by the utility model is：A kind of anti-seizing mechanism of weeding, including gearbox, shaft and knife are provided Disk, the shaft are set as two, and by gearbox driving rotation on gearbox, shaft is mutually parallel two shafts, described Cutterhead is set to one end of shaft, and anti-tangle sheath is equipped between the cutterhead and gearbox, and anti-tangle sheath is socketed in the outer of shaft It encloses；The anti-tangle sheath includes jacket and inner sleeve, and one end of housing is detachably connected on gearbox, the other end of housing and Cutterhead is equipped with gap, and the inner sleeve is actively socketed between housing and shaft, and the lower end of inner sleeve and cutterhead offset.

It refers to putting on outside equipped with connecting flange that one end of the housing, which is detachably connected on gearbox, and housing passes through connection Flange and connection bolt are connected with gearbox.

After using the above structure, the anti-seizing mechanism of the utility model weeding between gearbox and cutterhead by being arranged anti-tangle shield Set, anti-tangle sheath includes jacket and inner sleeve, and inner sleeve is actively socketed between housing and shaft, and the lower end of inner sleeve and cutterhead offset, Anti-tangle sheath can prevent weeds to be wound into shaft, when countershaft is adjusted, inner sleeve can with cutterhead rising or under It drops and rises or falls, and keep the contact with cutterhead, ensure that cutter shaft is not exposed and so that weeds is entered countershaft and is wound, Not only ensured that the rotation of cutterhead and shaft was unaffected, but can achieve the purpose that it is antiwind, reduce resistance, avoid causing in gearbox Parts damage, working efficiency can be greatly improved.

Specific implementation mode

The utility model is described in detail below in conjunction with drawings and examples.

As shown in Figure 1, Figure 2, Figure 3 shows, the utility model weeding mechanism, including gearbox 1, shaft 2 and cutterhead 4, shaft 2 are set It it is two, two shafts 2 are rotated by the driving of gearbox 1 on gearbox 1, and are mutually parallel, and the both ends of two shafts 2 extend Go out gearbox 1, one end and driving mechanism（It is not drawn into figure）Connection, one end are arranged cutterhead 4, are equipped between cutterhead 4 and gearbox 1 Anti-tangle sheath 3, anti-tangle sheath 3 are socketed in the periphery of shaft 2；Anti-tangle sheath 3 includes housing 31 and inner sleeve 32, one end of housing 31 It is detachably connected on gearbox 1, the other end and cutterhead 4 of housing 31 are equipped with gap, and inner sleeve 32 is actively socketed on 31 He of housing Between shaft 2, the lower end of inner sleeve 32 and cutterhead 4 offset.

The utility model in the specific implementation, between having between inner sleeve 32 and shaft 2 and between inner sleeve 32 and housing 31 Gap, i.e. inner sleeve 32 be rotatable between housing 31 and shaft 2, sliding, when the position of cutterhead 4 needs adjustment, inner sleeve 32 with The carry out activity up and down of shaft 2 offsets under gravity with cutterhead 4, between capable of preventing between housing 31 and cutterhead 4 Gap enters weeds, that is, can guarantee the normal rotation of shaft 2, can also achieve the purpose that the application.

It refers to that housing 31 is equipped with connecting flange that one end of the utility model housing 31, which is detachably connected on gearbox 1, Housing is connected by connecting flange and connection bolt and gearbox 1.

By the way that anti-tangle sheath 3 is arranged between gearbox 1 and cutterhead 4, anti-tangle sheath 3 can for the utility model weeding mechanism Weeds are prevented to be wound into shaft 2, when countershaft 2 is adjusted, inner sleeve 32 can prevent 4 gap location of housing 31 and cutterhead Weeds enter and countershaft 2 is wound, and have not only ensured that the rotation of cutterhead 4 and shaft 2 is unaffected, but also can reach antiwind mesh , resistance is reduced, the damage for causing the parts in gearbox 1 is avoided, working efficiency can be greatly improved.
