Abstract

The utility model discloses a spiral combination rotary efficient cutter, comprising a plurality of rotary cutting tools, wherein each cutting tool is composed of a cutting body and a cutting head (3) and an axle hole (10) is opened in the center of the cutting body and a plurality of cutting head rotary arms (7) are mounted on the cutting body and an arc cutting head (3) is mounted on each rotary arm; the rotary cutting tools are staggered with each other by a given angle and mounted on the axle; pressure disks are mounted on the two ends of the rotary cutting tools. The spiral combination rotary efficient cutter has features of large pressure intensity of the spiral cutting tool on the material, saved labor, low energy consumption and high efficiency of the whole device, increased efficiency by 2-3 times compared with the similar products, enlarged cutting same-diameter angle of the cutting tool, easy and efficient material breakage, being free from vegetative state effect, stable operation, safety, reliability, splicing of the rotary arm and the cutting head, easy and simple disassembly and assembly, long service life and wide application range.

Description

Spiral combined rotary high-efficient cutter

Technical field the utility model relates to the chopping processing unit (plant) of a kind of herbaceous plant, rubber, plastics, is a kind of spiral combined rotary high-efficient cutter specifically.

The existing herbaceous plant of background technology, rubber, the machinery of plastics class cutting is many to be finished with blade cut or hammering, machinery from grass cultivation processing, existing hay cutter chaffcutter be the sizable blade that is complementary with the feeding mouth width, be fixed on the knife rest of rotor, drum-type is arranged, side cut and hammering type are several, though drum-type and the acting of side cut have certain shear angle when shearing, but when thicker or boundling material passes through, the advantage of shear angle performance is limited, the boundling material produces then consumes big energy with joint efforts, need high-power driving could guarantee its acting requirement, the very big pressure of high-power generation acts on the material, loosen fast again after cutting, its active force and reaction force recur, and make axle produce anisosthenic power variation, form strong body and tremble, Here it is existing hay cutter can not the high-speed and high-efficiency running the very crux, its power is big more, and danger coefficient is high more, and the life-span is short more.Another significant drawbacks of prior art be all cutter all by bolted owing to there is not anti-loosening safeguard, cause great hidden danger to safety in production, injury accident happens occasionally thus.

In addition, existing cutting machine is influenced by vegetative state, and the influence as the different conditions such as dried, wet, soft, tough of stalk influences its efficient, and the cutter of exploitation low power consuming, high efficiency and security of operation is that problem to be solved is held in current market.

The summary of the invention the purpose of this utility model is to provide a kind of spiral combined rotary high-efficient cutter, and it has drawn back cutting of cutlery and has cut with the footpath angle, easily and effectively crack material, energy-efficient, reduce production costs, improve security performance, applied range.

The technical solution of the utility model is as follows:

This device is made up of the multi-disc rotary cutter, and every cutter is made of cutter hub and cutter head, and the center of cutter hub has axis hole, adorns a plurality of cutter head spiral arms on the cutter hub, and each spiral arm is installed an arc cutter head; Every rotary cutter given angle that staggers is contained on the axle; There is platen at the two ends of multi-disc rotary cutter.

2-6 cutter head spiral arm of dress on each cutter hub.

Uniform lightening hole on the above-mentioned cutter hub.

On the above-mentioned spiral arm lightening hole is arranged, spiral arm outer end and cutter head junction are thick.

Above-mentioned cutter head and spiral arm are pegged graft.

Above-mentioned cutter head and spiral arm are that side is hung.

The utility model advantage is: 1, shear history of this device is identical by a plurality of shapes, narrower blade is applied on the axle with the footpath, the every given angle that staggers, the knife edge are with the footpath helical arrangement, and its angle of shear can surpass 120 degree on one group of cutter, under the drive of axle, during rotational shear, the blade of narrow cutter cooperates shearing with the footpath successively with stationary knife, equates to whole moment from beginning, compared with prior art active force and reaction force are corresponding reduces, and has guaranteed stability, the security of operation.Efficient increases substantially simultaneously, raises the efficiency 2-3 doubly than similar machines.2, not need each and every one that screw is set fastening for how many blades of this device, only frictionally positioning and directing rotation of axle and blade during transmission, cutter was obstructed when exceeding its torsion when spout was strayed into other harder objuct product, and axle then slides and dallies, guarantee that cutter hub was not subjected to large impact, safety is guaranteed.3, this device has drawn back the same footpath of the shearing angle of cutlery, cracks material easily and effectively, not influenced by vegetative state.4, spiral arm and cutter head are pegged graft, and easy disassembling is easy, long service life.5, applied range is contained in the hay cutter and can replaces blade, raises the efficiency, and optimizes the crudy of forage grass.

Description of drawings Fig. 1 is the utility model monolithic cutter structure schematic diagram;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is side hanging cutter head structure figure;

Fig. 4 is that the B of Fig. 3 is to view;

Fig. 5 is the arm structure schematic diagram of side hanging.

The utility model is described in further detail below in conjunction with accompanying drawing for the specific embodiment.

By Fig. 1--2 can see, this device is made up of the multi-disc rotary cutter, and every cutter is made of cutter hub and cutter head 3, and the center of cutter hub has axis hole 10, uniform 3 lightening holes 9 on the cutter hub, adorn 3 cutter head spiral arms 7 on the cutter hub, lightening hole 8 is arranged on each spiral arm, spiral arm outer end and cutter head junction 5 are thicker, arc cutter head 3 is used to peg graft, the 4th, plug, the cutter head outer rim has cutter eyebrow 2,1st, point of a knife; Every rotary cutter given angle that staggers is contained on the axle.The 6th, the loss of weight boundary, the spiral arm internal diameter is thin to be to be convenient to compress cutter head after satisfying the combination of many group cutters, with anti-loosening.The sheet of cutter is several fixed according to needs, and cutter eyebrow 2 can be decided the angle that staggers of every cutter; Promptly descend the outer top of a slice cutter cutter head last slice cutter eyebrow, there is platen at multi-disc rotary cutter two ends, all rotary cutters are compressed install on the axle.

Can see by Fig. 3-5 another connected mode of cutter head and spiral arm the cutter head side being suspended on the spiral arm 7 that the projection 12 of cutter head is embedded in the hole 13 of spiral arm, and the spiral arm head also is embedded in the groove 11 of cutter head.This connected mode is fit to small type.
