Abstract

The utility model relates to a chopping device. The chopping device solves the problem that the prior branch chopping device only can chop the timber, but cannot convey the chopped timber to a great height or a great distance by using the wind power generated by the knife roller. The chopping device comprises an axle (1), at least two spoke plates (2), a plurality of knife clips (3), a plurality of cutting knives (4), a plurality of cutting knife base plates (5), a shell (6), a dead knife (8) and an electric motor (9), wherein the number of the knife clips (3), the cutting knives (4) and the cutting knife base plates (5) is consistent, the axle (1) penetrates through the centers of the at least two spoke plates (2) and is fixedly connected with the at least two spoke plates (2), and a plurality of fan blades (7) are fixedly installed between every two spoke plates (2). The utility model can convey the chopped timer to the great height or the great distance without being matched with an air blower or a screw-propeller, thereby the cost is reduced, the structure is simplified, and the utility model is fully suitable for the traveling operation.

Description

The branch shredding mechanism

Technical field

The utility model relates to a kind of branch shredding mechanism.

Background technology

The rotor of existing branch shredding mechanism is the cylindrical of sealing, this rotor can only shred timber and the timber of chopping can not be transported to eminence or distant place, if the timber of chopping is transported to eminence or distant place, needs to be equipped with in addition fan blower, thereby be not suitable for the energy forest combined harvester.

The utility model content

The utility model purpose provides a kind of branch shredding mechanism, can only shred timber and can not utilize the wind-force of rotor self generation that the timber that shreds is transported to eminence or problem at a distance to solve existing branch shredding mechanism.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: shredding mechanism of the present utility model is made up of axle, two disc, several hold(ing)-down clips, several cutting knifes, several cutting knife seat boards, housing, bed plate, several fan propeller and motors at least, and the quantity correspondence of described hold(ing)-down clip, cutting knife and cutting knife seat board is identical; Described every disc is positioned at housing, described axle passes the centre bore of every disc and affixed with every disc successively, the two ends of described axle are contained on the housing, have several uniform right angle gap on the periphery of described every disc, right angle gap on described adjacent two disc is corresponding one by one to be provided with, be fixed with uniform cutting knife seat board on the long one to one right angle face at least two disc, be fixed with a cutting knife on each cutting knife seat board, be fixed with a hold(ing)-down clip on each cutting knife, bed plate is packed in the bottom in the housing, have feeding mouth and discharging opening on the described housing, the output shaft of motor is rotationally connected with axle, is fixed with several fan propeller between per two disc.

The beneficial effects of the utility model are: shredding mechanism is provided with fan propeller, when tool roller axis drives cutting knife rotation chopping timber, also drive the fan propeller rotation and produce wind-force, fan blower or spiral propeller be need not be equipped with and just eminence or distant place the timber of chopping can be delivered to, thereby reduced cost, simplified the structure, be applicable to the propelled type operation fully, be particularly useful for the branch shredding mechanism of energy forest.
