Description
Technical field
The utility model belongs to agricultural machinery device field, more particularly to a kind of straw chopping and returning machine pulverizing chamber.
Background technology
Agricultural crop straw refers in agricultural production process, root under being remained after harvest wheat, corn and other crops,
Stem, leaf the like waste.With the increase year by year of the cultivated area and yield of crop, effectively handle a large amount of agricultural crop straws and seem
It is particularly urgent.Mechanized Straw returning to the field technology can preferably handle a large amount of stalks in field, reduce the air that crop straw burning is caused
Pollution, the stalk of returning to the field can also be effectively increased the soil organism, and improved soil structure lifts soil fertility, promotes microorganism to live
Property and plant growth.Straw chopping and returning machine as core in Mechanized Straw returning to the field technology equipment, its performance it is fine or not right
The implementation of whole technology plays vital effect.Straw chopping and returning machine is general by pulverizing chamber, running gear, power train
The compositions such as system, crushing rotor, during equipment operation, crushing knife rotates at a high speed, by the method impact cutting crop material cut without support,
And stalk is sucked in casing in the presence of the negative pressure at feeding mouth, stalk by multiple impact cutting, the comprehensive function such as tear, rub
After be ground into section or threadiness, the stalk finally shredded is dished out by air-flow from pulverizing chamber scatters earth's surface.Stalk is thin after crushing
Broken degree and the uniformity in ground mulching, directly affect the seeding quality, seed of follow-up tillage free or reducing seeder germination and
Growth, and then influence the yield of crop.Pulverizing chamber is the critical component of straw chopping and returning machine, crushes the situation pair of indoor air flow
The crushing quality of stalk, shed breadth, speed and the uniformity and all have a major impact.Existing straw chopping and returning machine pulverizing chamber
Housing is typically all to be made up of several sections of bending plates, and crushing Indoor Flow Field is not good, and the stalk after crushing is different in size and sheds inequality
It is even.
The content of the invention
The purpose of this utility model is typically all by several sections of foldings for the housing of existing straw chopping and returning machine pulverizing chamber
Bent plate is constituted, and crushing Indoor Flow Field is not good, and the stalk after crushing is different in size and sheds a kind of uneven stalk of deficiency proposition
Crushing and returning to field machine pulverizing chamber, it is characterised in that the straw chopping and returning machine pulverizing chamber includes procapsid 1, left plate 2, right side
Plate 3 and back casing 4, are provided with crushing rotor 5 between left plate 2 and right plate 3.
It is described on right plate 3, crush rotor 5 be mounted below baffle plate 6, baffle plate 6 is fixed by 4 bolts.
The back casing 4 is made up of inclined-plane 41 and horizontal plane 42, and the right and left between inclined-plane 41 and horizontal plane 42 is each
It is welded with 2 reinforcements 7.
The procapsid 1 is made up of upper plane 11, curved surface 12, lower plane 13 and vertical folding surface 14, in lower plane 13
The right and left is respectively welded with two suspension plates 8；The plane equation of the curved surface 12 is R=281 × eθ, wherein 0≤θ≤120/
359；A suspension ear 9 is respectively welded with the right and left of upper plane 11.
The beneficial effects of the utility model are that pulverizing chamber procapsid of the present utility model is designed to spiral case curved surface, and increase is crushed
Fluid inside flow velocity, heightens stalk and crushes quality and deployment uniformity, pulverizing chamber right flank has the baffle plate installed by bolt, made
Crush rotor installation and removal convenient.
