Abstract
The utility model discloses a spiral straw crushing device, which belongs to the technical field of agricultural machinery. The spiral straw crushing device is characterized by consisting of a frame and two groups of rotary knife rolls, wherein the frame consists of two side plates and a cross beam; the two groups of rotary knife rolls are arranged on the frame; the rotary knife rolls consist of knife rests and spiral blades and are provided with drive shafts which are fixed on the side plates through bearing blocks; chain wheels are arranged at one ends of the drive shafts; the power is transmitted to the rotary knife rolls through the chain wheels for pushing the rotary knife rolls to rotate; two fixed blades are fixed on the cross beam; and the two groups of spiral knives have opposite rotating directions. The utility model has the beneficial effects that the moving blades of the spiral straw crushing device and the fixed blades form the inclined shearing during the rotation so as to save the power. In addition, when the two groups of rotating knife rolls rotate, maize straws are centralized towards the middle by using a push force towards the middle and are convenient to collect.
Description
Technical field
The utility model belongs to agricultural machinery technological field.
Background technology
At present, used straw millstone on the known maize harvesting machine, a kind of is flail knife formula shredder bar, another kind of formula pressure-bearing type rotating knife chip cutting knife.Such straw millstone consumption of power is big, the crushed stalk weak effect.
Summary of the invention
The purpose of this utility model is: a kind of spirality straw millstone is provided, it is installed on the maize harvesting machine, can reduce moving knife consumption, improve the crushed stalk effect.
The technical solution of the utility model is: the framework that the spirality straw millstone is made up of two side plates and crossbeam and be installed in that two groups of rotation rotors on the framework form.The rotation rotor is made up of knife rest and helical blade.On the rotation rotor power transmission shaft is installed, power transmission shaft is fixed on the side plate with bearing block, and an end of power transmission shaft is equipped with sprocket wheel, by sprocket wheel power is sent to the rotation rotor, and the rotation rotor is rotated.On crossbeam, fix two ledger-plates, utilize the shearing of screw blade and ledger-plate, maize straw is pulverized.The rotation direction of two groups of circular knifes is opposite, when the rotation rotor rotates, produces the thrust to the centre, and after two row maize straws were pulverized during operation, the directed throwing sent in the middle of two ridges.Maize harvesting machine can be according to its operation line number, and at configuration one group or array spirality straw millstone, per two row dispose one group of spirality straw millstone.
The beneficial effects of the utility model are: the knife section of the spirality straw millstone that provides forms inclined cutting with ledger-plate when rotated, saves power.In addition, two groups are rotated rotors when rotated, and the thrust of oriented centre makes the maize straw of chopping concentrate to the centre, is convenient to collect.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, side plate, the 2nd, bearing block, the 3rd, knife rest, the 4th, helical blade, the 5th, power transmission shaft, the 6th, bolt, the 7th, bearing block, the 8th, sprocket wheel, the 9th, ledger-plate, the 10th, crossbeam.
In Fig. 1, bearing block 2 is installed on the side plate 1.Helical blade 4 usefulness bolts 6 are fixed on the knife rest 3, form the rotation rotor.By power transmission shaft 5 and bearing block 2 two groups of rotation rotors are fixed on the side plate 1.Sprocket wheel 8 is fixed on an end of power transmission shaft 5.
In Fig. 2, ledger-plate 9 is fixed on the crossbeam 10, and the two ends of crossbeam 10 and side plate 1 welding form framework.
This spirality straw millstone can be configured on the maize harvesting machines such as 2 row, 4 row, 6 row as required.
