Abstract

The utility model relates to a rotary cultivator rotation-type lawnmower, and relates to an accessory device on a rotary cultivator, which aims at solving the problems of the prior rotary cultivator that the grass is easy to be wound on the plough coulter shaft to influence the normal work of the rotary cultivator. The utility model provides a rotary cultivator rotation-type lawnmower, which comprises a fixed sawtooth and two bearing seats, which are axially fixed on a plough coulter shaft of the rotary cultivator, wherein the bearing seat is provided with a rotating shaft, and a shell is provided with a shell gear, and the rotating shaft is provided with a rotating shaft gear, and the rotating shaft gear is engaged with the shell gear; the rotating shaft is provided with a rotation sawtooth; when the plough coulter shaft rotates, the rotation sawtooth can be contacted with the fixed sawtooth to cut the grass which is wound on the fixed sawtooth. The rotation-type rotary cultivator lawnmower has simple structure and remarkable grass cutting effect.

Description

The rotatable grass cutter of a kind of rotovator

Technical field

The utility model belongs to the rotovator mechanical field, the auxiliary equipment on particularly a kind of rotovator.

Background technology

Rotovator is when farming, rotation along with coulter shaft, weeds between the field also can be gone up rotovator by volume and be wrapped on the coulter shaft, when the weeds of twining can have a strong impact on rotovator work more for a long time, cause coulter shaft to be twined consequences such as dead stall, existing some rotovator also is equipped with mowing-apparatus, but its mowing effect is undesirable, can not be effectively with the weeds excision that is wrapped on the coulter shaft.

The utility model content

Twine grass easily for solving on the existing rotovator coulter shaft, influence the problem of rotovator operate as normal, the utility model provides, and its embodiment is as follows:

This grass cutter comprises the fixedly sawtooth that is fixedly mounted on vertically on the rotovator coulter shaft, and the coulter shaft upper edge on stationary saw flank limit is axially installed with two bearing blocks, and rotating shaft is installed on the bearing block;

The casing gear coaxial with coulter shaft arranged on the casing at coulter shaft inner termination place, and there is shaft gear at rotating shaft inner termination place, and shaft gear is meshed with the casing gear;

The rotation sawtooth is installed in the rotating shaft, and the weeds that the rotation sawtooth can touch with the stationary saw toe joint and will be wrapped in when coulter shaft is rotated on fixing sawtooth are cut off.

The course of work of the rotatable grass cutter of this rotovator is as follows:

In cultivating procedure, along with the rotation of rotovator coulter shaft, weeds often turn to along coulter shaft and promptly radially are wrapped on the coulter shaft, also promptly radially are coated on fixedly on the sawtooth; On the other hand, in rotovator coulter shaft rotary course, because shaft gear is installed on the casing gear and with the casing gear and is meshed, shaft gear not only revolves round the sun with coulter shaft, himself also carries out rotation under the reaction of casing gear, cut off when the rotation sawtooth turns to the weeds shearing that can will be wrapped in when touching with the stationary saw toe joint on fixing sawtooth like this.

This straight formula rotovator grass cutter is simple in structure, and the mowing effect is remarkable.

As preferred version of the present utility model, fixedly the sawtooth tiltable is fixed on the coulter shaft.

Fig. 2 is the vertical view of the rotatable grass cutter of a kind of rotovator of the utility model.

Embodiment

The rotatable grass cutter of a kind of rotovator as shown in Figure 1 comprises the fixedly sawtooth 3 that tilts to be fixedly mounted on vertically on rotovator 2 coulter shaft 1, and fixedly coulter shaft 1 upper edge of sawtooth 3 sides is axially installed with two bearing blocks 9, and rotating shaft 6 is installed on the bearing block 9;

The casing gear 7 coaxial with coulter shaft 1 arranged on the casing 8 at coulter shaft 1 inner termination place, and there is shaft gear 5 at rotating shaft 6 inner termination places, and shaft gear 5 is meshed with casing gear 7;

Rotation sawtooth 4 is installed in the rotating shaft 6, and rotation sawtooth 4 can be cut off with the weeds that fixing sawtooth 3 contacts and will be wrapped on fixing sawtooth 3 when coulter shaft 1 is rotated.
