Abstract
The utility model discloses a double-row seed opener of an arc-shaped spring single disk, which comprises a vertically-arranged arc-shaped spring, seed conveying tubes symmetrically arranged on the left side and the right side of the arc-shaped spring, a pair of concave disks, a pair of protective plates and a pair of connection shafts. The lower end of the arc-shaped spring is fixedly connected with the connection shafts, the other ends of the connection shafts are fixedly connected with the concave disks through bearings and are matched with the concave disks in rotating mode, the seed conveying tubes are arranged behind the connection shafts and fixedly connected onto the connection shafts, and gaps are reserved between the inner sides of the concave disks and the seed conveying tubes. The protective plates are arranged under the connection shafts and extend backwards to the back side of the seed conveying tubes from a tangency point of the inner lateral surfaces of the concave disks and the forward direction, and the protective plates are fixedly connected with the seed conveying tubes. When a large amount of straw exists on the ground surface after rotary tillage, the double-row seed opener has good passing performance, can effectively control ditching depth and achieves the effect of even seeding depth, and the seed opener is light in weight and low in manufacture cost. The double-row seed opener of the arc-shaped spring single disk can be installed on a machine frame of a strip-sowing seeder and is used for ditching seeding of crops including millet, wheat and the like.
Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of seed-furrow opener, specifically a kind of semielliptic spring table roller divided boot.
Background technology
At present the seed opener kind is more, comprising: arrow spade type, boot-foot type, double-disk, face table roller formula etc. directly.Though all there are some shortcoming and defect in every kind of each tool advantage of plough.What domestic market employing now was more is double disk opener, and its basic structure is formed close, and the degree of depth is distinguished to some extent but connected mode and control are ditched.Though adopt the plough of linkage can effectively control the trench digging degree of depth, the structure more complicated, weight is big, cost is high.Though adopt the fixing plough of straight-bar spring that weight saving, cost are reduced, unsteady effect of plough and controlling depth are not too desirable.
Present stage is domestic except no-tillage seeding is adopted in some areas, and most areas particularly are located in the area of two seasons of Plain plantation, all is behind the results preceding crop; Straw chopping and returning is planted wheat behind the whole ground again; Though soil property is softer, there is a large amount of stalks on the face of land, causes the through performance of most ploughs bad; Seed level differs greatly, and causes the sowing effect not ideal.
The utility model content
The technical problem that the utility model will solve; Provide a kind of semielliptic spring table roller divided boot; Exist under a large amount of stalk situation on the face of land after the rotary tillage; Have good through performance, can effectively control the trench digging degree of depth, reach the seed level effect of uniform, and the weight of plough own is light, manufacturing cost is lower.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of semielliptic spring table roller divided boot comprises the semielliptic spring of vertical setting, and each is a pair of also to comprise grain tube, concave disk, backplate, the connecting axle that is symmetricly set in the semielliptic spring left and right sides;
The lower end and the connecting axle of semielliptic spring connect firmly, and the other end of connecting axle connects firmly and is rotatably assorted through bearing and concave disk;
Grain tube is located at the connecting axle rear and is fixed on the connecting axle through link arm, leaves the gap with the inboard of concave disk;
Backplate is positioned at the below of connecting axle, extends back from the point of contact of concave disk medial surface and direction of advance, and the rear of grain tube is located in its rear end; Backplate and grain tube connect firmly.
As a kind of qualification of the utility model, connecting axle is horizontally disposed with and the angle β of it and the projection of semielliptic spring on horizontal plane is an acute angle; Correspondingly, be the distribution of Eight characters shape between two concave disks.
As further qualification, 80 °≤β < 90 °.
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art, the technological progress that is obtained is: utilize the elasticity of semielliptic spring itself, when sower is worked; Make plough when soil property and face of land situation change; Semielliptic spring is adjusted stressing conditions at any time under stressed condition of different, it is even to reach seed level; Replace two disk trench diggings with the concave disk trench digging that is fixed on the connecting axle two ends,, reduced advance resistance greatly, improved the trafficability characteristic of plough except effectively cutting off or push down the stalk weeds; Two concave disks are fixed on the semielliptic spring through connecting axle, have simplified syndeton greatly, have reduced manufacturing cost; Directly send into seed in kind of the ditch with grain tube and backplate, avoided seed to be sprinkling upon on stalk and the ground surface soil effectively.The utlity model has simple in structure, assembling and characteristics easy to operate, with low cost, to power require relatively lowly, operating efficiency is high, has saved manpower and materials.
The utility model can be assemblied on the seeder depositing seed frame, is used for water furrow plantings such as millet, wheat.
To combine Figure of description and specific embodiment that the utility model is done further explain below.
Description of drawings
Fig. 1 is the vertical view of the embodiment of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1-semielliptic spring, 2-grain tube, 3-concave disk, 4-backplate, 5-connecting axle, 6-bearing box, 7-link arm.
Embodiment
Embodiment
Fig. 1 and shown in Figure 2 be a kind of semielliptic spring table roller divided boot, comprise the semielliptic spring 1 of vertical setting, each is a pair of also to comprise the grain tube 2 that is symmetrically set in semielliptic spring 1 left and right sides respectively, concave disk 3, backplate 4, connecting axle 5.
Semielliptic spring 1 is smooth L template shape, the spring steel material, and the lower end of semielliptic spring 1 connects firmly connecting axle 5.
Connecting axle 5 is horizontally disposed with, and it and the angle β of semielliptic spring 1 between the projection on the horizontal plane be acute angle, 80 °≤β < 90 °.
The other end of connecting axle 5 connects firmly and is rotatably assorted through bearing and concave disk 3 in the center of concave disk 3 (to connecting axle direction depression).Correspondingly, two 3 of concave disks are the distribution of Eight characters shape, are the on-line operation member of trench digging action.
Bearing is located in the bearing box 6.
Retaining soil when backplate 4 is used to ditch, with guarantee the seed that from grain tube, falls down fall into ditched in.Backplate 4 is positioned at the below of connecting axle 5, extends back from the point of contact of concave disk 3 medial surfaces and direction of advance, its rear end is located at the rear that arrives grain tube 2.Backplate 4 connects firmly with grain tube 2.
Present embodiment fixedly is assemblied in the top of semielliptic spring 1 on the sower frame in use, can be used for the water furrow planting of crops such as millet, wheat by its drive.
