Abstract

The utility model relates to a straw chopper for cutting fibered fine stuff in the agriculture. The plain-cutter straw chopper in the prior technology adopts two synchromesh gears to make the blade and the V-shaped groove on the roller mesh and chop materials, and the complete engagement of a blade and a V-shaped groove and the phenomenon of chopping materials incompletely can be ensured. The utility model, straw chopper, adopts a plurality of cutters distributed uniformly on a main shaft and the blades on the same cylindrical surface are contacted with surface of adjacent rollers. The knife roller and straw eating wheel bring the materials which are fed in from the inlet opening to the place between the two rollers while rotating to chop the materials and then throw materials out of a discharge door.

Description

Cut up with a hay cutter careless device

Technical field

The utility model relates to the hand hay cutter grass device that worker, agriculture cut staple fines hay cutter tool use.

Background technology

The technical scheme that existing Patent document number is 00213706.2 record is a kind of roller cutter hay cutter, by a pair of driving shaft and the driven axle that rotates synchronously with the control of number of teeth gear.The rotor that is made of several radial distribution cuttves is arranged on the driving shaft; The roller rotor that the v-depression that holds the rotor blade is housed on the driven axle interacts with roller, and the stalk that drive feeds from import etc. cut off its extruding.The problem that exists as can be seen from the roller cutter hay cutter of said structure is, materials such as stalk cut off not thorough, can not adjust after the cutting blade abrasion, and complex structure

Summary of the invention

The problem that the utility model exists at prior art.Its objective is a kind of manufacturing simple in structure, easy is provided, should has extensively, hand hay cutter grass device that fracture is effective.

To achieve these goals, the hand hay cutter of the technical solution of the utility model grass device comprises casing, and casing is provided with charging aperture and discharging opening.Driving shaft and servo axis are housed in the casing.One end of driving shaft stretches out outside the casing.Be equipped with fixed number on the driving shaft uniform cutting knife, cutoff edge is leant on rotor on the face to an external circle.Be equipped with the cylindric smooth roll that joins with rotor on the servo axis.

Rotor is by radially adjustable cutting knife, is positioned on the knife rest by bolt to constitute.

Smooth roll is to be made of bent the first day of the lunar month material or the rubber layer of becoming one of table.

During application, the overhanging end of driving shaft receives power rotates rotor, and the fibre materials such as stalk that feed from charging aperture are brought into, and are cut off under the interaction on cutting knife blade and smooth roll surface, dish out from discharging opening.

Hand hay cutter grass device from the above mentioned owing to adopted the interactional version on the blade of the rotor on the driving shaft and the smooth roll surface on the servo axis, replaces pasturing taking turns with rotor and has simplified mechanism.Therefore having realized promptly having simplified mechanism has guaranteed the cut effect of material again.

Description of drawings

Fig. 1 shows the structural representation of the hand hay cutter grass device of present embodiment;

Fig. 2 shows the A-A cutaway view of the hand hay cutter grass installation drawing 1 of present embodiment.

Embodiment

Hand hay cutter grass device in the present embodiment comprises casing 1, and casing 1 is provided with charging aperture 2 and discharging opening 3.Driving shaft 4 and servo axis 5 are housed in the casing 1.One end of driving shaft 4 stretches out outside the casing.Be used to install the member of accepting power.The rotor 7 that the knife rest 10 of cutting knife 9 is made of bolt 11 location 5 is housed at driving shaft 5.Servo axis 5 is equipped with by circle to be leant on body and becomes the first day of the lunar month material of one or the smooth roll 6 that rubber layer 8 constitutes.The surface engagement of cutting knife 9 blades and smooth roll 6.The double wheel that pastures of rotor interacts the material cut-out of feeding with smooth roll.
